Description

  The present invention relates to a key, and more particularly, to a key that makes it possible to provide a cylinder lock key that is low in cost, highly convenient for a user, and high in safety.

  Cylinder locks are used in gaming machines in game halls, so-called pachinko parlors in pachinko parlors, to prevent unauthorized operation by a third party. On the other hand, in order to allow game machines to easily manage gaming machines, one gaming field requires that one key can lock or unlock the cylinder lock provided in each gaming machine. Is done.

  If the key of the cylinder lock is lost, or a wrong key is created, or if there is a risk of unauthorized unlocking, the cylinder lock must be replaced with something that can be locked or unlocked with another key. There wasn't. In this case, if a large number of new cylinder locks that can be locked or unlocked with one key are prepared, a large amount of cost is required. Also, it took time and effort to replace the cylinder lock.

  Therefore, for example, when a gaming machine is newly purchased, it is necessary that the cylinder lock provided in the gaming machine can be locked or unlocked (unlocked) with an already used key. Since an old plate-shaped key cannot be used to unlock a new lock, a cylinder lock that can be switched from an old lock to a new lock with high safety has also been proposed (see, for example, Patent Document 1).

Furthermore, a small and inexpensive cylinder lock that can change the key code, and a safe and small cylinder lock has also been proposed (see, for example, Patent Document 2). This makes it possible to increase the key code without changing the size (length) of the cylinder lock.

  By the way, the cylinder lock cannot be unlocked unless the right and left surfaces of the key insertion portion are correctly inserted when the key is inserted. In particular, when key codes are set on both the left and right sides of the key insertion part, it is important for the user to recognize whether the left and right sides of the key insertion part are correctly inserted.

  However, if the key used in Patent Document 1 is used, it is possible to prevent the right and left surfaces of the key insertion portion from being erroneously inserted in reverse, but this key has a complicated cross-sectional shape and is a machine tool. In some cases, for example, the key manufacturing cost may be high.

  Moreover, in the cylinder lock used in Patent Document 2, a reversible key that can unlock the cylinder lock even if the left and right surfaces of the key insertion portion are inserted in reverse can be used. The lock requires an opening / closing plate spring for urging a plurality of opening / closing plates to be attached to predetermined positions inside the inner peripheral cylinder, and the structure becomes complicated.

  The present invention has been made in view of such a situation, and is intended to provide a cylinder lock key that is low in cost, highly convenient for the user, and high in safety.

  The key according to the present invention is a key used for unlocking or locking the cylinder lock, and is provided on each of the left and right surfaces of the insertion portion inserted into the key hole of the cylinder lock with respect to the key insertion direction. A groove having a corresponding shape is formed, and at the distal end of the insertion portion, one of the upper and lower ends in the vertical direction perpendicular to the key insertion direction has a tapered shape, and the other is an edge. .

  In the key of the present invention, a groove having a shape corresponding to the key code is formed on each of the left and right surfaces of the insertion portion inserted into the keyhole of the cylinder lock with respect to the key insertion direction. 1, one of the upper and lower end portions in the vertical direction perpendicular to the key insertion direction has a tapered shape, and the other is an edge.

  Accordingly, it is possible to prevent erroneous insertion of the respective surfaces of the key insertion portion with respect to the key insertion direction.

  The cylinder lock has a locking member provided so as to be movable in the vertical direction perpendicular to the key insertion direction inside the key hole, and the key hole is inserted into the key hole due to the tapered shape of the tip part. The locking member is moved to a position where the locking member does not lock with the tip, and the locking member locks the tip with the edge of the tip to prevent the insertion portion from being inserted into the keyhole. Can do.

  A plurality of plates are moved in the vertical direction perpendicular to the insertion direction of the key according to the shape of the groove provided on both surfaces of the insertion portion, and each of the plates is moved according to the shape of the groove corresponding to the preset key code. When moved in the first direction, the cylinder lock can be unlocked by moving in the left-right direction with respect to the key insertion direction of the sidebar that has locked the rotation of the cylinder.

  The plate and the side bar may be provided at positions that are line-symmetric at the center of the keyhole.

  Therefore, the number of key codes that can be set can be increased even with a small cylinder lock.

  According to the present invention, it is possible to provide a key for a cylinder lock that is low in cost, highly convenient for a user, and high in safety.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 and 2 show an example of the appearance of a cylinder lock 100 to which the present invention is applied. FIG. 1 is a perspective view of the external appearance of the cylinder lock 100 on the front end side. FIG. 2 is a perspective view of the appearance of the rear end side of the cylinder lock 100.

  Inside the outer peripheral cylinder 101 of the cylinder lock 100, an inner peripheral cylinder 103 that rotates together with the key when a regular key is inserted is provided. In a state where the inner peripheral cylinder 103 is disposed inside the outer peripheral cylinder 101, a key hole 103a provided in the inner peripheral cylinder 103 into which a key insertion portion is inserted is exposed from the outer peripheral cylinder 101 to the outside. That is, the outer cylinder 101 is provided so as to cover the outer periphery of the inner cylinder 103 (like a cover).

  Further, a notch 101h-1 and a notch 101h-2 are provided on the front end face of the outer cylinder 101. When the key insertion portion is not located at the position corresponding to the notch 101h-1 or the notch 101h-2 of the outer cylinder, the key insertion portion cannot be inserted or removed.

  When unlocking the cylinder lock 100, a key insertion portion is inserted into the key hole 103a and rotated 90 ° clockwise, for example. In the cylinder lock 100, when resetting the key code as described later, a key insertion portion is inserted into the key hole 103a and rotated, for example, 135 ° counterclockwise.

  A switch case 102 is provided at the rear of the outer cylinder 101. The outer cylinder 101 and the switch case 102 are fixed to each other by a pin 105-1 and a pin 105-2 on the opposite side of the pin 105-1. ing. When the cylinder lock 100 is unlocked, the switch case 102 has a switch 114 that generates an electrical signal indicating that the cylinder lock 100 has been unlocked, and a connector of the switch 114 that is exposed at the rear of the switch case 102. 114a is connected to a predetermined part such as a power supply unit of a gaming machine, for example, and supplies an electrical signal indicating that the cylinder lock 100 is unlocked to the power supply unit or the like.

  FIG. 3 is a perspective view showing the configuration of the cylinder lock 100. As shown in the figure, the inner peripheral cylinder 103 is configured to be inserted inside the outer peripheral cylinder 101, and is configured to be rotatable inside the outer peripheral cylinder 101. Further, the inner peripheral cylinder 103 has a concave portion in a shape that fits with the convex portion 111a of the ratchet disc 111 at the rear portion (on the side opposite to the keyhole 103a in the drawing), and the ratchet disc 111 is rotated with its own rotation. Rotate.

  The switch cylinder 113 is configured to be inserted into the switch case 102 and is configured to be rotatable within the switch case 102. The switch cylinder 113 is configured to engage with the ratchet disk 111, and when the inner peripheral cylinder 103 is rotated, the switch cylinder 113 is also rotated together with the ratchet disk 111. Further, the switch cylinder 113 is urged toward the switch 114 by the spring 112 in a state of being inserted into the switch case 102.

  The rear surface of the switch cylinder 113 (on the switch 114 side) is provided with a convex portion at a predetermined position. When the switch cylinder is rotated by a predetermined angle, the convex portion on the rear surface of the switch cylinder 113 is By abutting the convex portion 114 b of the switch 114, the convex portion 114 b of the switch 114 is pressed and an electrical signal is output from the connector 114 a of the switch 114.

  Further, although not shown here, the shape of the rear portion of the inner peripheral cylinder 103 is configured to regulate the rotation of the inner peripheral cylinder 103 in correspondence with the shape of the front end portion of the switch case 102. For example, when the inner peripheral cylinder 103 is rotated 90 ° clockwise (clockwise) from the state where the cylinder lock 100 is locked, the convex portion provided at the rear part of the inner peripheral cylinder 103 is formed at the front end of the switch case 102. The inner cylinder 103 is prevented from rotating further in the right direction by abutting against the provided convex portion.

  In order to reduce the size of the cylinder lock 100, it is necessary to sufficiently reduce the convex portion 114b of the switch 114. For example, an error (backlash) in the key insertion direction occurs in the size or shape of the switch cylinder 113 or the like. In this case, the convex portion on the rear surface of the switch cylinder 113 does not properly contact the convex portion 114b of the switch 114, and an electrical signal is output from the connector 114a even though the cylinder lock 100 is unlocked. There is concern that it will disappear. In the cylinder lock 100 of the present invention, the switch cylinder 113 is urged toward the switch 114 by the spring 112 in a state of being inserted into the switch case 102. Even if there is a backlash, the convex portion on the rear surface of the switch cylinder 113 can be brought into contact with the convex portion 114b of the switch 114 accurately.

  The switch case 102 is configured such that a front circumferential end portion 102c abuts against the inner peripheral cylinder 103 and an outer surface thereof abuts against an inner surface of the outer peripheral cylinder 101. Is configured to be attached. Further, the hole 102f provided on the circumferential end portion 102c in front of the switch case 102 is located behind the side bar 151-1 (on the switch case 102 side) as will be described later when the cylinder lock 100 is reset. The end of this is a hole to be inserted.

  The switch 114 is fixed to the switch case 102 by inserting the pin 115-1 and the pin 115-2 into the hole 114c and the hole 114d, respectively, in a state of being inserted into the switch case 102. Yes. The switch case 102 is configured to have a circular shape on the front side but has a rectangular surface on the rear side. Therefore, the switch 114 can be reliably and easily configured by the pins 115-1 and 115-2. Can be fixed.

  Further, as shown in the figure, the inner peripheral cylinder 103 includes open / close plates 131-1 to 131-4, tumbler plates 133-1 to 133-4, open / close plates 131-21 to 131-24, and tumbler. Plates 133-21 to 133-24 are attached.

  Each of the opening / closing plates 131-1 to 131-4 operates so as to enable the rotation of the inner peripheral cylinder 103 or to suppress the rotation depending on its position with respect to the inner peripheral cylinder 103. The open / close plates 131-1 to 131-4 are engaged with the tumbler plates 133-1 to 133-4 through the engagement holes, respectively.

  For example, an engagement hole 131-1a constituted by three holes is provided in the upper part of the opening / closing plate 131-1 in the figure, and an engagement hole also constituted by three holes in the lower part of the figure. 131-1b is provided. On the other hand, the tumbler plate 133-1 is provided with any one of an engagement pin 133-1b having a diameter that engages with any one of the engagement holes 131-1a and an engagement hole 131-1b. An engagement pin 133-1c having a diameter to be engaged is provided.

  Accordingly, the engagement pin 133-1b and the engagement pin 133-1c are engaged with any one of the engagement hole 131-1a and the engagement hole 131-1b, respectively, and thereby The tumbler plate 133-1 is engaged. Then, when the opening / closing plate 131-1 and the tumbler plate 133-1 are engaged, the positions of the opening / closing plate 131-1 and the tumbler plate 133-1 in the vertical direction in the figure are determined. Here, the vertical direction is a direction orthogonal to the direction in which the key is inserted in the inner cylinder 103, and is indicated by three engagement holes 131-1a or 131-1b in the opening / closing plate 131-1. The direction in which the holes are arranged.

  In this example, the engagement hole 131-1a and the engagement hole 131-1b are each composed of three holes, so that the position of the open / close plate 131-1 and the tumbler plate 133-1 in the vertical direction in the drawing is 3 One of the streets.

  The open / close plate 131-1 can be moved in the vertical direction in the figure, but is attached to the inner cylinder 103 so as not to move in the key insertion direction. On the other hand, the tumbler plate 133-1 is movable in the vertical direction in the drawing in accordance with the movement of the opening / closing plate 131-1, while being attached to the inner peripheral cylinder 103, and the movement of the side bar 151-1. Along with this, it is also possible to move in the key insertion direction. Therefore, by moving the side bar 151-1 in the key insertion direction, the engagement pin 133-1b and the engagement pin 133-1c described above, and the engagement hole 131-1a and the engagement hole 131-1b are connected. The engagement, that is, the engagement between the opening / closing plate 131-1 and the tumbler plate 133-1 can be released or re-engaged.

Although the engagement between the opening / closing plate 131-1 and the tumbler plate 133-1 has been described here, the other opening / closing plates and the tumbler plate are engaged in the same manner as in the case of the opening / closing plate 131-1 and the tumbler plate 133-1. In the cylinder lock 100, the key code is determined by determining the positions of the opening / closing plate and the tumbler plate in the vertical direction in the drawing. That is, 81 (= 3 ⁴ ) key codes can be set by engaging the open / close plates 131-1 to 131-4 and the tumbler plates 133-1 to 133-4, respectively.

  Each of the opening / closing plates 131-21 to 131-24 and the tumbler plates 133-21 to 133-24 has the same configuration as the opening / closing plates 131-1 to 131-4 and the tumbler plates 133-1 to 133-4. The opening and closing plates 131-1 to 131-4 and the tumbler plates 133-1 to 133-4 are attached so as to face each other around the key hole 103a of the inner peripheral cylinder 103.

  That is, the open / close plates 131-21 to 131-24 and the tumbler plates 133-21 to 133-24 are respectively connected to the open / close plates 131-1 to 131-4 and the tumbler plates 133-1 to 133-4 and the keyhole 103a. Are provided at positions that are line-symmetrical at the center position. That is, the open / close plates and the tumbler plates on both the left and right sides of the keyhole 103 a of the inner peripheral cylinder 103 are attached to positions that are symmetric with respect to the vertical line segment passing through the rotation axis of the inner peripheral cylinder 103.

Therefore, in the cylinder lock 100, the open / close plates 131-1 to 131-4 and the tumbler plates 133-1 to 133-4 are engaged, respectively, and the open / close plates 131-21 to 131-24 and the tumbler plates 133-21 to By respectively engaging 133-24, 6561 (= 3 ⁸ ) key codes can be set.

  In the key for unlocking or locking the cylinder lock 100, the projections of the opening / closing plates 131-1 to 131-4 and the projections of the opening / closing plates 131-21 to 131-24 are provided on both sides of the insertion portion inserted into the keyhole 103a. A groove into which the part is inserted is provided. The vertical positions of the open / close plates 131-1 to 131-4 and the open / close plates 131-21 to 131-24 are determined according to the shape of the groove of the key insertion portion.

  As described above, in the key for unlocking or locking the cylinder lock 100, the respective shapes of the grooves provided on both surfaces of the key insertion portion are key codes.

  For example, if the open / close plate and tumbler plate are arranged in a line in the depth direction of the cylinder lock, it is necessary to add the open / close plate and the tumbler plate to the depth of the cylinder lock when increasing the key code. As a result, the length of the cylinder lock in the depth direction is further increased. However, in the cylinder lock 100 of the present invention, the opening / closing plates 131-21 to 131-24 and the tumbler plates 133-21 to 133-24 Each is attached to a position that is line-symmetric with respect to the central positions of the opening / closing plates 131-1 to 131-4 and the tumbler plates 133-1 to 133-4 and the keyhole 103 a, so that the size (length) of the cylinder lock can be increased. It is possible to increase the key code without changing it.

  The side bar 151-1 is pressed against the inner surface of the outer cylinder 101 by the side bar spring 152-1 and the side bar spring 152-2. The side bar 151-1 or 151-2 is engaged with a recess provided on the inner surface of the outer cylinder 101 or is disengaged, thereby restricting the rotation of the inner cylinder 103 with respect to the outer cylinder 101.

  The side bar 151-1 is configured to be movable in a direction orthogonal to the key insertion direction along a side bar hole (not shown) provided in the inner cylinder 103. In a state where the cylinder lock 100 can be unlocked, a part of the side bar 151-1 is a recess 133-1 a to 133-4 a of the tumbler plates 133-1 to 133-4 (only 133-1 a is shown here). The side bar 151-1 moves in a direction orthogonal to the key insertion direction and inward of the cylinder lock 100 (a direction approaching the rotation axis of the inner cylinder 103). As a result, the fitting between the recess provided on the inner surface of the outer cylinder 101 and the side bar 151-1 is released, and the inner cylinder 103 can rotate.

  On the other hand, in the state where the cylinder lock 100 is locked, the side bar 151-1 abuts on the side surface of the tumbler plates 133-1 to 133-4 other than the recesses 133-1a to 133-4a. The bar 151-1 is a direction perpendicular to the key insertion direction and cannot move inward of the cylinder lock 100, and as a result, the recess provided on the inner surface of the outer cylinder 101 and the side bar 151-1 The fitting is not released, and the inner cylinder 103 cannot be rotated.

  Note that the side bar 151-1 is normally in a direction orthogonal to the key insertion direction by the side bar spring 152-1 and the side bar spring 152-2, and the outer direction of the cylinder lock 100. That is, it is biased in the direction of fitting with a recess provided in the inner surface of the outer cylinder 101.

  The side bar 151-1 is structured to be movable in the key insertion direction along a side bar hole provided in the inner peripheral cylinder 103. In a state where the key code of the cylinder lock 100 is reset, the side bar 151-1 moves in the key insertion direction and moves behind the cylinder lock 100 (on the switch case 102 side). As a result, as the side bar 151-1 moves, the tumbler plates 133-1 to 133-4 also move in the key insertion direction, and the open / close plates 131-1 to 131-4 and the tumbler plates 133-1 to 133-3. The key code is reset by releasing the engagement with 4 respectively.

  As described above, when the side bar 151-1 moves in a direction orthogonal to the key insertion direction, the positions of the tumbler plates 133-1 to 133-4 are not changed. In addition, when the side bar 151-1 moves in the key insertion direction, the tumbler plates 133-1 to 133-4 move in the key insertion direction in accordance with the movement of the side bar 151-1. Yes. Each of the tumbler plates 133-1 to 133-4 is configured to fit into a tumbler plate hole (not shown) provided in the side bar 151-1, for example, with the movement of the side bar 151-1. Thus, it can also be moved in the key insertion direction.

  On the other hand, each of the opening / closing plates 131-1 to 131-4 is configured to fit into an opening / closing plate hole (not shown) provided in the inner cylinder 103 and cannot move in the key insertion direction. It is configured as follows.

  Therefore, when the side bar 151-1 is in the key insertion direction and moves rearward of the cylinder lock 100 (on the switch case 102 side), the tumbler plates 133-1 to 133 are moved along with the movement of the side bar 151-1. -4 also moves in the key insertion direction, and the engagement between the open / close plates 131-1 to 131-4 and the tumbler plates 133-1 to 133-4 is released.

  Further, the side bar 151-1 is normally biased to the rear side of the cylinder lock 100 (on the switch case 102 side) by the side bar spring 152-3 in the key insertion direction. It moves in the key insertion direction according to the shape of the front and back sides of 101 and the shape of the front end surface of the switch case 102.

  Here, the operation of the side bar 151-1 has been described, but the same operation is performed for the side bar 151-2. However, in the case of the side bar 151-2, the moving direction when the key code of the cylinder lock 100 is reset is different from the case of the side bar 151-1. That is, the side bar 151-2 is normally biased forward of the cylinder lock 100 in the key insertion direction by the side bar spring 152-13, and the key code of the cylinder lock 100 is reset. , The side bar 151-1 moves in the key insertion direction and forward of the cylinder lock 100. As a result, the opening / closing plates 131-21 to 131-24 and the tumbler plates 133-21 to 133-24 The key code is reset by releasing the engagement.

  The insertion pin 175 is inserted into the hole 103 b of the inner peripheral cylinder 103. The insertion pin 175 is biased downward in the figure by the spring 172 in a state where the inner cylinder 103 is inserted into the outer cylinder 101, and the end 175a of the insertion pin 175 is inserted into the key hole 103a in the inner cylinder. It is made to protrude.

  As described above, each shape of the groove provided on both surfaces of the key insertion portion is a key code. As will be described later, the insertion pin 175 prevents the left and right surfaces of the key insertion portion from being inserted by mistake. In other words, if the key is inserted with the left and right surfaces of the key insertion portion reversed, a part of the tip of the key insertion portion comes into contact with the insertion pin 175 so that the key cannot be inserted. Yes.

  In the cylinder lock 100 of the present invention, the opening / closing plates 131-21 to 131-24 and the tumbler plates 133-21 to 133-24 are respectively connected to the opening / closing plates 131-1 to 131-4 and the tumbler plates 133-1 to 133-1. 133-4 and the key hole 103a are attached at positions that are symmetrical with respect to the center of the key hole 103a, so that a groove for identifying the key code is provided on both sides of the key insertion portion. Of course, the shapes of the left and right grooves of the insertion portion are different from each other. When such a key is inserted into the cylinder lock 100, it is determined in advance whether the surface of the insertion portion is directed to the left or right with respect to the longitudinal direction of the key hole 103a (key insertion direction). If this direction is mistakenly inserted, the cylinder lock 100 cannot be unlocked or reset.

  In the cylinder lock 100 of the present invention, the insertion pin 175 prevents the key insertion portion from being inserted in the wrong direction with respect to the key insertion direction of each surface.

  Further, the end 175a abuts on the upper end surface in the drawing of the key insertion portion inserted into the key hole 103a, so that the key insertion portion is inserted into the key hole 103a and stabilized.

  Since the key insertion portion is inserted into the keyhole 103a, it is necessary to be configured to be slightly smaller than the keyhole 103a. For this reason, in a state where the key insertion portion is inserted into the key hole 103a, the insertion portion may slightly move in the vertical direction in the figure. In this case, along with the movement of the key insertion part in the vertical direction in the figure. The opening / closing plate also moves in the vertical direction. As a result, the vertical position in the figure of the tumbler plate engaged with the opening / closing plate is shifted from the position of the side bar, and the cylinder lock cannot be unlocked.

  In the cylinder lock 100 of the present invention, the end 175a of the insertion pin 175 urged downward in the figure by the spring 172 contacts the upper end face in the figure of the key insertion part, and the key insertion part is illustrated. Since the urging is performed in the middle-down direction, it is possible to prevent the key insertion portion from moving slightly in the vertical direction in the figure. In addition, since the spring 172 is inserted into the hole 103b and then locked so as not to protrude from the hole 103b, the spring 172 is also endless even when the inner cylinder 103 is rotating. The portion 175a comes into contact with the upper end surface of the key insertion portion in the figure and continues to urge the key insertion portion.

  In order to prevent the key insertion portion from moving finely in the vertical direction in the figure, for example, each of the opening and closing plates may be biased by a spring or the like. It is necessary to attach to the peripheral cylinder, which increases the number of parts. Further, if each of the opening and closing plates is biased by a spring or the like, the convex portion of the opening and closing plate that comes into contact with the key insertion portion may be worn, and the durability of the cylinder lock will be reduced.

  In the cylinder lock 100 of the present invention, a spring or the like for urging each of the opening and closing plates is not necessary, so that the number of parts can be reduced and durability can be maintained.

  Further, the end portion 175a of the insertion pin 175 abuts on the upper end surface of the key insertion portion in the figure and urges the key insertion portion in the downward direction in the drawing, so that it can be slightly moved in the vertical direction in the drawing. In addition, it is also possible to prevent the key from moving slightly in the key insertion direction. This is because the lower end surface of the key insertion portion urged downward in the drawing comes into contact with the lower surface of the key hole 103a of the inner peripheral cylinder, thereby causing friction.

  FIG. 4A is a diagram showing the outer appearance of the outer cylinder 101, and FIG. 4B is a diagram of the outer cylinder shown in FIG. 4A as seen from another angle. FIGS. 4c and 4d are diagrams illustrating the configuration of the front and back surfaces of the outer cylinder 101. For the sake of clarity, the cylindrical portions of the outer cylinder 101 of FIGS. 4a and 4b are virtually removed, respectively. It is said that. As shown in FIG. 4c and FIG. 4d, the front and back surfaces of the outer peripheral cylinder 101 have different shapes depending on their positions, and when the side bar 151-2 moves as the inner peripheral cylinder rotates, A hole 101f is provided at a position where the front (outer cylinder 101 side) end of the side bar 151-2 contacts.

  With the key insertion portion inserted in the key hole 103a, the inner cylinder 103 is rotated counterclockwise by a predetermined angle (for example, 135 °), and the rear end portion of the side bar 151-1 (on the switch case 102 side) 3) is moved to the same position as the hole 102f in FIG. 3, the rear end portion of the side bar 151-1 is inserted into the hole 102f, and the side bar 151-1 is in the key insertion direction and the cylinder lock Move backwards.

  At this time, when the front end of the side bar 151-2 (end on the outer cylinder 101 side) has moved to the same position as the hole 101f in FIG. 4c or 4d, the front end of the side bar 151-2 has the hole 101f. The side bar 151-2 is moved in the key insertion direction and forward of the cylinder lock.

  As the sidebar 151-1 and the sidebar 151-2 move in the key insertion direction, the tumbler plates 133-1 to 133-4 and the tumbler plates 133-21 to 133-24 also move in the key insertion direction. Thus, the open / close plates engaged with the respective tumbler plates are not brought into contact with the tumbler plates, and the engagement between the tumbler plate and the open / close plate is released. As a result, the key code is reset in the cylinder lock 100.

  When the reset is completed and a new key is inserted and the inner cylinder 103 is rotated clockwise, the engagement pin of each tumbler plate that has been disengaged and the engagement hole of each open / close plate are released. Re-engage at a position corresponding to the key code of the new key. As a result, a new key code can be set for the cylinder lock 100.

  In the reset, the inner cylinder 103 is rotated counterclockwise by a predetermined angle while the key insertion portion is inserted into the key hole 103a, and the key insertion portion corresponds to the notch 101h-2 of the outer cylinder. This can be done only when it has been moved to a position. This is because if the key insertion portion is not located at the position corresponding to the notch 101h-2 of the outer cylinder, the key insertion portion cannot be inserted or removed.

  Further, as shown in FIGS. 4a to 4d, the inner surface of the outer peripheral cylinder 101 is provided with recesses 101d-1 to 101d-3 that fit with the side bars 151-1 or 151-2, respectively. It is configured in a groove shape.

  When the regular key is not inserted into the cylinder lock 100, the side bar 151-1 is fitted with the recess 101d-1 of the outer cylinder 101, and the side bar 151-2 is the recess of the outer cylinder 101. 101d-2 is fitted so that the inner cylinder 103 cannot be rotated.

  When a regular key is inserted into the cylinder lock 100, as described above, a part of the side bar 151-1 is fitted into the recesses 133-1a to 133-4a of the tumbler plates 133-1 to 133-4. Accordingly, the side bar 151-1 is movable in the direction perpendicular to the key insertion direction and inside the cylinder lock 100 (in the direction approaching the rotation axis of the inner cylinder 103), and the side bar 151-2. Similarly, it is possible to move inward of the cylinder lock 100 (in a direction approaching the rotation axis of the inner peripheral cylinder 103). As a result, the fitting between the recess 101d-1 provided on the inner surface of the outer cylinder 101 and the side bar 151-1 is released, and the fitting between the recess 101d-2 and the side bar 151-2 is released. The inner cylinder 103 can be rotated.

  Further, when a regular key is inserted into the cylinder lock 100 and rotated 90 ° clockwise, the cylinder lock 100 is unlocked. At this time, the side bar 151-2 is attached to the inner surface of the outer cylinder 101. It fits with the recessed part 101d-3 provided in this. Thereby, when the cylinder lock 100 is unlocked, a click feeling transmitted to the user's hand through the key is obtained. Further, the positions of the inner cylinder and the key can be stabilized in the unlocked state, and the output state of the electric signal when the cylinder lock 100 is unlocked can be stably maintained.

  Next, a mechanism for unlocking the cylinder lock 100 will be described. FIG. 5 is a view showing the external appearance of the cylinder lock 100 in a state where the key is not inserted (that is, in a locked state), and FIG. 6 is a cross-sectional view of the cylinder lock 100 in the plane A of FIG.

  7 is an enlarged view of a portion surrounded by a circle A in FIG. 6, and FIG. 8 is an enlarged view of a portion surrounded by a circle B in FIG. As shown in FIG. 7, the tumbler plate 133-21 and the open / close plate 131-21 have the engagement pins 133-21b (or the engagement pins 133-21c) as described above, and the engagement holes 131-21a (or By engaging with the engagement holes 131-21b), they are in contact with each other. Further, as shown in FIG. 8, the tumbler plate 133-1 and the opening / closing plate 131-1 have the engagement pin 133-1b (or the engagement pin 133-1c) as described above. (Or engagement holes 131-1b) are brought into contact with each other by engaging.

  FIG. 9 is a front view of the cylinder lock 100 in a state where the key is not inserted (ie, locked), and FIG. 10 shows the cylinder lock 100 in the state of FIG. 9 at a predetermined depth position. It is sectional drawing of the state cut | disconnected.

  As shown in FIG. 9, the end 175a of the insertion pin 175 protrudes into the key hole 103a in the inner peripheral cylinder.

  As shown in FIG. 10, in a state where no key is inserted, the open / close plate 131-1 or 131-21 is positioned on the lower side in the figure.

  In this state, the tumbler plate 133-1 or 133-21 whose position is determined in accordance with the vertical position of the opening / closing plate 131-1 or the opening / closing plate 131-21 is also located on the lower side. The concave portion 133-1a does not coincide with the convex portion 151-1a of the side bar 151-1 in the vertical direction in the figure, and the concave portion 133-21a of the tumbler plate 133-21 is not the side bar 151-2. The convex portion 151-2a and the vertical position in the figure do not match.

  Although not shown in the drawing, the convex portion 151-1a on the left side of the side bar 151-1 is actually the same as the convex portion 151-2a on the right side of the side bar 151-2 in the drawing. It is made up of.

  Further, in this state, the side bar 151-1 is fitted with the recess 101 d-1 provided on the inner surface of the outer peripheral cylinder 101, and the side bar 151-2 is provided on the inner surface of the outer peripheral cylinder 101. The inner cylinder 103 cannot be rotated.

  As shown in FIG. 11, when a key 190 (a regular key that can unlock the cylinder lock 100) is inserted into the cylinder lock 100, the state of each part inside the cylinder lock 100 is the same as the state shown in FIG. It changes as shown in FIG.

  When the left and right surfaces of the key insertion portion are correctly inserted in the insertion of the insertion portion of the key 190 into the key hole 103a of the cylinder lock 100, the insertion pin 175 may be When the key is inserted with the left and right surfaces of the key insertion part reversed, the tip of the key insertion part is partially inserted into the insertion pin 175. So that the key cannot be inserted. A detailed configuration of the key 190 will be described later.

  FIG. 12 is a cross-sectional view of the cylinder lock 100 at the same position in the depth direction as FIG. 10, and is a cross-sectional view when the key 190 is inserted into the cylinder lock 100.

  In the same figure, the protrusions 131-1e or 131-21e of the opening / closing plate are inserted into the grooves provided on both surfaces of the insertion portion 191 of the key 190. As a result, the tumbler plate 133-1 or 133-21 moves in the vertical direction in the drawing together with the open / close plate 131-1 or 131-21. In this case, compared with the state shown in FIG. 10, the tumbler plate 133-1 or 133-21 is moved upward, and as a result, the recess 133-1a of the tumbler plate 133-1 is moved to the side bar 151. -1 convex portion 151-1a and the vertical position in the drawing coincide with each other, and the concave portion 133-21a of the tumbler plate 133-21 is the same as the convex portion 151-2a of the side bar 151-2 in the vertical direction in the drawing. The position matches.

  Although only the tumbler plate 133-1 and the tumbler plate 133-21 have been described here, the tumbler plates 133-2 to 133-4 or the tumbler plates 133-22 to 133-3 are inserted when a proper key is inserted. 24, the concave portions 133-2a to 133-4a or the concave portions 133-22a to 133-24a are formed on the upper and lower sides of the convex portion 151-1a of the side bar 151-1 or the convex portion 151-2a of the side bar 151-2. The direction positions will match. That is, since the key code of the regular key matches the key code set in the cylinder lock 100, the positions of the concave portions of all the tumbler plates are moved so as to match the positions of the convex portions of the side bars.

  In this state, the side bar 151-1 is fitted to the concave parts 133-1a to 133-4a of the tumbler plates 133-1 to 133-4 by fitting the convex parts 151-1a of the side bar 151-1. It is possible to move in the direction orthogonal to the key insertion direction and inward of the cylinder lock 100 (left side in the figure). Further, by inserting the convex portion 151-2a of the side bar 151-2 into the concave portions 133-21a to 133-24a of the tumbler plates 133-21 to 133-24, the side bar 151-2 is inserted in the key insertion direction. It is possible to move the cylinder lock 100 in the inner direction (right side in the figure).

  When the key 190 is rotated clockwise as shown in FIG. 13 from the state shown in FIG. 11, the state of each part inside the cylinder lock 100 is as shown in FIG. 14 from the state shown in FIG. To change.

  14 is a cross-sectional view of the cylinder lock 100 at the same predetermined depth direction position as FIG. 12 (or FIG. 10), and is a cross-sectional view when the key 190 is rotated. When the regular key is inserted, as described above, the positions of the concave portions of all the tumbler plates are moved so as to coincide with the positions of the convex portions of the side bars, so that the side bars 151-1 and the side bars 151- 2 is urged toward the inner side of the cylinder lock 100, the side bar 151-1 and the side bar 151-2 move in the direction perpendicular to the key insertion direction and toward the inner side of the cylinder lock 100. The fitting between the recess 101d-1 and the recess 101d-2 provided on the inner surface of the cylinder 101 is released, and the inner cylinder 103 can be rotated.

  That is, when the key 190 is rotated, the inner cylinder 103 is also rotated accordingly. At this time, the side bar 151-1 and the side bar 151 are formed along the shape of the recess 101 d-1 or 101 d-2. -2 is urged toward the inside of the cylinder lock 100. As a result, the inner cylinder 103 is rotated as shown in FIG.

  When the key 190 is further rotated clockwise as shown in FIG. 15 from the state shown in FIG. 13, the state of each part inside the cylinder lock 100 is shown in FIG. 16 from the state shown in FIG. To change. In FIG. 15, the key 190 is rotated 90 degrees clockwise from the state shown in FIG. That is, in the state of FIG. 15, the cylinder lock 100 is unlocked and an electrical signal is output from the connector 114a.

  FIG. 16 is a cross-sectional view of the cylinder lock 100 at the same predetermined depth direction position as FIG. 14, and is a cross-sectional view when the key 190 is rotated 90 ° clockwise. In the same figure, the side bar 151-1 moves in the direction perpendicular to the key insertion direction and inward of the cylinder lock 100 as in the case of FIG. 14. 14, unlike the case of FIG. 14, the cylinder lock 100 is not moved inward, but is fitted to the recess 101 d-3 on the inner surface of the outer cylinder 101.

  That is, the side bar 151-2 is fitted with a recess provided on the inner surface of the outer cylinder 101 in a direction orthogonal to the key insertion direction by the side bar spring 152-11 and the side bar spring 152-12. Since the inner cylinder 103 (key 190) is rotated 90 ° clockwise, it is moved to a position corresponding to the recess 101d-3 provided on the inner surface of the outer cylinder 101. When this occurs, the side bar 151-2 moves in a direction perpendicular to the key insertion direction and engages with the recess provided on the inner surface of the outer cylinder 101, and engages with the recess 101d-3. Thus, the fitting between the side bar 151-2 and the recess 101d-3, which is performed when the cylinder lock 100 is unlocked, is transmitted to the user's hand as a click feeling through the key. Further, the positions of the inner peripheral cylinder 103 and the key 190 can be stabilized in the unlocked state, and the output state of the electrical signal when the cylinder lock 100 is unlocked can be stably maintained.

  In the state where the regular key 190 is inserted, as described above, the positions of the concave portions of all the tumbler plates are moved so as to coincide with the positions of the convex portions of the side bars. If it is urged inward of the cylinder lock 100, it moves in the direction perpendicular to the key insertion direction and inward of the cylinder lock 100. Therefore, the recess 101d-3 provided on the inner surface of the outer cylinder 101 The mating with is released. Therefore, if the key 190 is rotated counterclockwise from the state shown in FIG. 15 or FIG. 16, the inner cylinder 103 is rotated and the cylinder lock 100 can be locked again.

  In FIG. 16, a recess (groove) may be provided at a position facing the recess 101 d-3 and in contact with the side bar 151-1.

  When the cylinder lock 100 is unlocked, the concave portion (the concave portion 101d-3) provided at the position in contact with the side bar on the inner surface of the outer cylinder 101 is provided to obtain a click feeling as described above. For example, unlike the concave portion 101d-1 and the concave portion 101d-2, it is not provided for restricting the rotation of the inner peripheral cylinder 103, so that the sidebar 151-1 is unlocked. Alternatively, it may be sufficient to be provided at a position corresponding to one of the side bars 151-2.

  As described above, in the cylinder lock 100 of the present invention, in order to obtain a click feeling, the click feeling can be obtained by utilizing the shape of the side bar and the outer cylinder without particularly increasing the number of parts. In addition, when the cylinder lock is unlocked, the unlocked state can be maintained.

  Next, the structure of the key that can unlock the cylinder lock 100 will be described.

  FIG. 17 is a perspective view showing a configuration of a key 190 to which the present invention is applied. As shown in the figure, a groove corresponding to the key code is provided in the insertion portion 191 of the key 190 which is a portion to be inserted into the key hole 103a. This groove is configured to be sandwiched between the surface 191a and the surface 191b.

  A part (convex part) of each of the opening / closing plates 131-1 to 131-4 or the opening / closing plates 131-21 to 131-24 described above is inserted into the groove of the insertion portion 191. The vertical position of the opening / closing plate is determined.

  Further, the groove of the insertion portion 191 is configured so that the width in the vertical direction (vertical direction) in the figure is wide at the distal end portion of the insertion portion 191, and when the insertion portion 191 is inserted into the keyhole 103a, for example, The protrusion 131-21e of the opening / closing plate 131-21 is inserted so as to be inserted into the groove. This groove has a wide width in the vertical direction in the drawing at the distal end of the insertion portion 191, but the vertical width in the drawing is almost equal to the width of the convex portion of the opening / closing plate in the other portions. Thus, the convex portion 131-21e contacts the surface 191a or the surface 191b of this groove and moves in the vertical direction, so that the vertical position of the opening / closing plate 131-21 changes. When the key 190 is completely inserted into the cylinder lock 100, the vertical position of the convex portion 131-21e is determined at a predetermined position of the groove, and the opening / closing plate 131-21 is attached to the key 190. It will be moved to the position corresponding to the key code.

  As described above, the cylinder lock 100 is not provided with a spring or the like for urging each of the opening and closing plates, and the opening and closing plates are orthogonal to the key insertion direction while being attached to the inner peripheral cylinder 103. It is configured to be movable in a direction (for example, the vertical direction in FIG. 12). Therefore, when the opening / closing plate moves upward, the convex portion of the opening / closing plate comes into contact with the surface 191b and is pushed up, and when the opening / closing plate moves downward, the convex portion of the opening / closing plate comes into contact with the surface 191a. Will be pushed down.

  Although the open / close plate is not urged by the spring, it can be said that it is urged downward by gravity.Therefore, when moving the open / close plate downward, it is not necessary to push it down. However, in order to surely move to the position corresponding to the key code, it is also necessary to press down the surface 191a.

  As described above, when a spring or the like for energizing each of the opening and closing plates is not provided, a surface (for example, a surface) that pushes the convex portion of the opening and closing plate upward when the shape corresponding to the key code is configured in the insertion portion 191. 191b) and a groove including a surface (for example, surface 191b) that pushes down the convex portion of the opening / closing plate downward needs to be appropriately formed. Further, when forming the shape corresponding to the key code in the insertion portion 191, if a groove including a surface that pushes the convex portion of the opening and closing plate upward and a surface that pushes the convex portion of the opening and closing plate downward is appropriately formed, for example, Even when foreign matter (dust or the like) adheres to the mounting portion of the opening / closing plate and the opening / closing plate does not move smoothly, the opening / closing plate can be reliably moved to the position corresponding to the key code.

In addition, the groove | channel corresponding to the key code of the insertion part 191 is provided also in the position on the opposite side to the position shown by FIG. The open / close plates 131-1 through 131-4 and the tumbler plates 133-1 through 133-4 are engaged, and the open / close plates 131-21 through 131-24 and the tumbler plates 133-21 through 133-24 are respectively engaged. Accordingly, in order to be able to set 6561 key codes (= 3 ⁸ ), naturally, it is necessary to provide grooves corresponding to the key codes on the left and right sides of the insertion portion 191.

  As described above, the key 190 of the present invention is a groove including a surface that pushes the convex portion of the opening / closing plate upward and a surface that pushes the convex portion of the opening / closing plate downward on the left and right sides of the insertion portion 191. Since the groove corresponding to the key code is provided, the number of key codes that can be set can be increased sufficiently, and the unlocking, locking, or resetting operation of the cylinder lock 100 is reliably performed. It is possible. Further, in the cylinder lock 100 that is unlocked by the key 190, a spring or the like that urges each of the opening and closing plates is unnecessary, so that the number of parts can be reduced and durability can be maintained. It becomes possible.

  In addition, the key 190 is provided with a recess 193 at a position where it comes into contact with the insertion pin 175 when the key 190 is completely inserted into the cylinder lock 100. Further, a notch 192 is provided at the rear end portion of the insertion portion 191 of the key 190, and when the key 190 is inserted into the cylinder lock 100 and rotated, the notch 192 holds the front end portion of the outer cylinder 101. It is designed to be rotated.

  Since the insertion portion 191 has grooves corresponding to the key codes on both the left and right sides, the central portion sandwiched between the grooves is configured to be thinner (less in thickness) than the other portions. The shape of the tip portion 194 of the central portion sandwiched between the grooves is such that the insertion pin 175 is pushed upward when the left and right surfaces of the insertion portion 191 are correctly inserted. When the key is inserted with the left and right surfaces of the insertion portion 191 reversed, the insertion portion 191 is in contact with and locked.

  18 and 19 are side views of the key 190, respectively. 18 is a diagram showing a left side surface when the key 190 is viewed from the distal end 194 side of the insertion portion 191 in FIG. 17. FIG. 19 is a diagram showing the key 190 in FIG. It is a figure which shows the right side when it sees from the front-end | tip part 194 side.

  As shown in FIG. 18, the groove corresponding to the key code provided on the left side surface of the insertion portion 191 of the key 190 is configured to be sandwiched between the surface 191c and the surface 191d. The key 190 is completely inserted into the cylinder lock 100 with the respective convex portions of the opening / closing plate 131-1 to the opening / closing plate 131-4 inserted in the groove configured to be sandwiched between the surface 191c and the surface 191d. When this is done, the positions of the concave portions of the tumbler plates 133-1 to 133-4 coincide with the positions of the convex portions 151-1a of the sidebar 151-1.

  As shown in FIG. 19, the groove corresponding to the key code provided on the right side surface of the insertion portion 191 of the key 190 is configured to be sandwiched between the surface 191a and the surface 191b. The shape of the groove corresponding to the key code provided on the right side surface of the insertion portion 191 of the key 190 is the shape of the groove corresponding to the key code provided on the left side surface of the insertion portion 191 of the key 190. It is configured to be different.

  The key 190 is completely inserted into the cylinder lock 100 with the respective convex portions of the opening / closing plate 131-21 to the opening / closing plate 131-24 inserted in the groove configured to be sandwiched between the surface 191a and the surface 191b. When this is done, the positions of the concave portions of the tumbler plates 133-21 to 133-24 coincide with the positions of the convex portions 151-2a of the sidebar 151-2.

  That is, when the key 190 is inserted into the cylinder lock 100 with the upward direction in the drawings in FIGS. 17 to 19 facing upward in the drawing in FIG. 1, the cylinder lock 100 can be unlocked by the key 190. This means that the left and right surfaces of the insertion part are correctly inserted.

  In FIG. 18 or FIG. 19, the tip end 194 of the insertion portion 191 has a rounded shape at the upper end in the drawing, and the lower end in the drawing is orthogonal to the key insertion direction. In the drawing, the shape has a straight line in the vertical direction. That is, the upper end portion of the distal end portion 194 of the insertion portion 191 is tapered to push up the insertion pin 175 upward, and the lower end portion of the distal end portion 194 of the insertion portion 191 is It is an edge for preventing the insertion of the key 190 by contacting the insertion pin 175.

  FIG. 20 is an enlarged view of a portion indicated by a circle in FIG. As shown in the figure, the upper end 194a of the tip 194 in the drawing is rounded, and the insertion pin 175 is moved upward while contacting the end 175a of the insertion pin 175. It has a tapered shape for pushing up. Also, the lower end 194b of the tip 194 in the figure has a shape having a straight line in the vertical direction in the figure orthogonal to the key insertion direction, and the left and right surfaces of the key insertion part are inserted in the opposite direction. Even if it abuts against the end 175 a of the insertion pin 175, the insertion pin 175 cannot be pushed upward, and as a result, the tip 194 is locked by the insertion pin 175. That is, the lower end 194b of the tip 194 in the figure is an edge for preventing the key 190 from being inserted.

  Further description will be given with reference to FIGS.

  22 is a cross-sectional view of the cylinder lock 100 in the plane B of FIG. In the figure, the tip 194 of the insertion portion 191 of the key 190 is inserted into the cylinder lock 100. In the case of FIG. 22, it is assumed that the left and right surfaces of the insertion portion 191 of the key 190 are correctly inserted.

  The end 175a of the insertion pin 175 is attached so as to be urged downward in the figure by the spring 172 so as to protrude into the key hole 103a in the inner cylinder, so that the insertion part 191 is inserted into the key hole 103a. The end portion 175a comes into contact with the distal end portion 194 of the insertion portion 191. However, as shown in FIG. 22, the upper end 194a of the tip 194 in the figure is tapered, so that the insertion pin 191 is inserted in the right direction in the figure, so that the insertion pin The insertion pin 175 is pushed upward while being in contact with the end portion 175a of the 175. As a result, the insertion portion 191 of the key 190 can be inserted further rightward from the state shown in FIG.

  When the key 190 is completely inserted into the cylinder lock 100, the end 175a of the insertion pin 175 comes into contact with the recess 193, and the key 190 is stabilized. That is, the end 175a of the insertion pin 175 biased by the spring 172 biases the insertion portion 191 in the downward direction in the drawing, and the fine movement of the key 190 in the vertical or horizontal direction in the drawing is suppressed.

  FIG. 23 is also a cross-sectional view of the cylinder lock 100 in the plane B of FIG. Also in this figure, the tip 194 of the insertion part 191 of the key 190 is inserted into the cylinder lock 100 as in the case of FIG. However, in the case of FIG. 23, unlike the case of FIG. 22, it is assumed that the left and right surfaces of the insertion portion 191 of the key 190 are inserted in reverse.

  In the case of FIG. 23, since the end portion 194b on the upper side of the tip portion 194 in the drawing (the lower side in the drawings in FIGS. 17 to 19) is an edge, After contact, the insertion pin 175 cannot be pushed upward. As a result, the insertion portion 191 of the key 190 cannot be inserted further rightward from the state shown in FIG.

  In the key 190 of the present invention, in order to sufficiently increase the number of key codes that can be set in the cylinder lock 100, grooves of different shapes are provided on the left and right sides of the insertion portion 191. Therefore, when the key 190 is inserted into the cylinder lock 100, if the right and left directions of the insertion portion 191 with respect to the key insertion direction are wrong, the cylinder lock 100 cannot be unlocked even with the regular key 190. For this reason, when the right and left direction with respect to the insertion direction of the key of the insertion part 191 is wrong, it is important to make a user aware of that.

  According to the present invention, when the left and right surfaces of the insertion portion 191 of the key 190 are correctly inserted, the key 190 can be completely inserted into the cylinder lock 100, and the left and right sides of the insertion portion 191 of the key 190 can be The key 190 can be prevented from being completely inserted into the cylinder lock 100 when the surface is inserted in reverse. Therefore, if the right and left direction of the insertion unit 191 with respect to the key insertion direction is incorrect, the user can be made aware of this.

  Even if the insertion pin 175 is broken and the key 190 is further inserted in the right direction from the state shown in FIG. 23, the position of the notch 192 is not appropriate. It cannot be inserted into 100 and rotated.

  Although the example in which the insertion pin 175 is provided on the upper side in FIG. 9 has been described above, the insertion pin 175 may be provided on the lower side in FIG.

  Further, the function of the insertion pin 175 is not limited to that realized by the pin. For example, a plate-like member can be used instead of the insertion pin 175.

  By the way, the cylinder lock 100 shown in FIG. 1 is adapted to be attached to, for example, a panel constituting a power supply unit of a slot game machine, and in a state where the cylinder lock 100 is attached to the panel of the power supply unit, A part of the front side (the side where the keyhole 103a is exposed) of the outer cylinder 101 is exposed to the outside of the power supply unit, and the other part is located inside the power supply unit.

  A predetermined electrical signal is supplied by soldering a harness or the like to the connector 114a of the switch 114 of the cylinder lock 100 and connecting the harness to the substrate of the power supply unit.

  However, there is an increasing need to attach the cylinder lock directly to a substrate such as a power supply unit.

  24 and 25 show an example of the appearance of a cylinder lock 200 to which the present invention is applied and which can be directly attached to a substrate. FIG. 24 is a perspective view of the external appearance of the cylinder lock 200 on the front end side. FIG. 25 is an external perspective view of the rear end portion side of the cylinder lock 200.

  The cylinder lock 200 is a cylinder lock that is unlocked, locked, or reset in the same manner as the cylinder lock 100, and is unlocked, locked, or reset using a key that is configured in the same manner as the key 190 in FIG. ing. That is, as with the cylinder lock 100, the cylinder lock 200 can be completely inserted into the cylinder lock 200 when the left and right surfaces of the insertion portion 191 of the key 190 are correctly inserted, Further, when the left and right surfaces of the insertion portion 191 of the key 190 are inserted in reverse, the key 190 cannot be completely inserted into the cylinder lock 200.

  Similarly to the cylinder lock 100, the cylinder lock 200 is provided with an inner peripheral cylinder 203 that rotates together with the key when a regular key is inserted inside the outer peripheral cylinder 201. In a state where the inner peripheral cylinder 203 is disposed inside the outer peripheral cylinder 201, the key hole 203a provided in the inner peripheral cylinder 203 into which the key insertion portion is inserted is exposed from the outer peripheral cylinder 201 to the outside. That is, the outer cylinder 201 is provided so as to cover the outer periphery of the inner cylinder 203 (like a cover).

  Unlike the case of the outer peripheral cylinder 101 of FIG. 1 or FIG. 2, the front end side of the outer peripheral cylinder 201 of FIG. 24 and FIG. 25 is not a so-called umbrella shape, but is configured as a pure cylinder. The other outer cylinder 201 has the same shape as that of the outer cylinder 101 of FIG. 1 or FIG.

  When unlocking the cylinder lock 200, a key insertion portion is inserted into the key hole 203a and rotated 90 ° clockwise, for example. Further, when resetting the key code in the cylinder lock 200, a key insertion portion is inserted into the key hole 203a and rotated, for example, 135 ° counterclockwise.

When the cylinder lock 200 is unlocked, the switch case 202 is internally provided with a switch 214 that generates an electrical signal indicating that the cylinder lock 200 has been unlocked, and a connector of the switch 214 that is exposed at the rear of the switch case 202. For example, 214a is soldered to a board such as a power supply unit of a gaming machine, and an electric signal indicating that the cylinder lock 200 is unlocked is supplied to the board.

  The connector 114a of the switch 114 shown in FIG. 2 is different from the connector 214a of the switch 214 shown in FIG. This is because the connector 114a is attached with a harness or the like, whereas the connector 214a is directly soldered to the substrate.

  Unlike the cylinder lock 100, the cylinder lock 200 is provided with a bracket 206. The bracket 206 is for stabilizing the cylinder lock 200 to which the connector 214a is attached by soldering to the board. The bracket 206 is fixedly attached to the switch case 202 by a bent portion 206a-1 and a bent portion 206a-2 (only the bent portion 206a-1 is shown in FIG. 25).

  That is, when the cylinder lock 200 is attached to the substrate, the end portions 206b-1 to 206b-4 and the end portion 206c (FIG. 25) of the bracket 206 are soldered to the substrate together with the connector 214a. Yes. By doing in this way, the cylinder lock 200 attached to the board | substrate can be stabilized more.
