JP-A-8-235327

  Since the gaming machine inter-table machines are arranged in a narrow space between the gaming machines, there is no room for installation space. Therefore, it is desirable to make the card reader / writer incorporated in such a device with limited installation space as small and compact as possible. If an automatic card transport mechanism such as a feed roller pair and a drive motor is provided, it is difficult to reduce the size and size. Therefore, it is desirable to use a manual insertion type card reader / writer that omits the automatic card transport mechanism and inserts a card by manual operation.

  In a manual insertion type card reader / writer, when an unlocking mechanism such as an electromagnetic solenoid breaks down or power supply is stopped, the inserted IC card cannot be ejected. In addition, if the inserted IC card has a large warp, the IC card is clogged inside, and the IC card may not be ejected only by the spring force. Accordingly, it is desirable that the card insertion / ejection mechanism is mounted also in the manual insertion type card reader / writer.

  Here, the card forced ejection mechanism described in the above-mentioned Patent Document 1 is suitable for an automatic insertion type IC card reader / writer equipped with a drive motor, and this is used as it is as a manual insertion type IC card. Cannot be used as a reader / writer. That is, in the case of the manual insertion type, a lock mechanism is provided for locking the inserted IC card in the insertion position, and the IC card cannot be ejected only by pushing out the IC card jammed inside. It is necessary to release the lock by the mechanism.

  In view of this, it is conceivable that the IC card locked state by the lock mechanism can be released by attaching the card removal member so as to be interlocked with the lock mechanism and operating the card removal member. However, in the case of such a card forced ejection mechanism, in a normal IC card insertion / ejection operation, the card ejection member that is a component of the card forced ejection mechanism operates unnecessarily in conjunction with the lock mechanism. End up.

  The card taking-out member is exposed to the outside from the case of the IC card reader / writer so that it can be operated manually. If this is operated unnecessarily, there is a risk that foreign matters such as dust will enter the case. When foreign matter that has entered the case is clogged with the lock mechanism, the spindle of the card removal member, etc., the drive load on these members increases, for example, the load on the electromagnetic solenoid for unlocking to release the lock mechanism increases. There is also a risk of disturbing the unlocking operation. Even if such a problem does not occur, an unnecessary load is always applied to the electromagnetic solenoid by the card take-out member interlocked with the lock mechanism.

  SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a card configured such that an operation lever operated when forcibly ejecting an IC card jammed therein does not operate during normal card insertion / ejection operation. It is to propose a manual insertion type IC card reader / writer equipped with a forced ejection mechanism.

  In order to solve the above problems, a card reader / writer according to the present invention includes a card insertion slot, a card holder that is pushed together with the card type storage medium when the card type storage medium is pushed from the card insertion slot, and the card holder. When a predetermined amount is pushed in, a holder lock lever that engages with the card holder and locks the card holder in its pushed-in position, and an unlocking direction in which the engagement of the holder lock lever with the card holder is released An unlocking member for moving the card holder, a card ejecting biasing member for pushing the card holder released from engagement with the holder lock lever toward the card insertion slot, and the inserted card-type memory A card forced ejection mechanism for forcibly ejecting the medium.

  The card forced ejection mechanism according to the present invention includes an operation lever operable from the first position toward the second position, a holding biasing member holding the operation lever at the first position, and the operation The movement of the lever is transmitted as a force that moves the holder lock lever in the unlocking direction, and the movement of the operation lever after unlocking the holder lock lever is transmitted as a force that pushes the card holder toward the card insertion slot. And a link mechanism.

  Further, in the forced card ejection mechanism of the present invention, when the operation lever is in the first position, the engaging portion of the link mechanism with the holder lock lever is out of the movement range of the holder lock lever. And the engaging portion of the link mechanism with the card holder is located outside the moving range of the card holder.

  In the card reader / writer of the present invention, the operation lever of the card forced ejection mechanism is in a state of being disconnected from the lock lever and the card holder, and normally the operation lever does not move even if the lock lever and the card holder move. Absent. When the operation lever is operated from the first position to the second position, the link mechanism for transmitting the movement of the operation lever is engaged with the holder lock lever and the card holder, and the holder lock lever is forcibly moved. The card holder is unlocked, and then the card holder is forced out toward the card insertion slot.

  Therefore, the operation lever and link mechanism of the card forced ejection mechanism do not operate during normal card insertion / ejection operations. It is possible to avoid problems such as foreign matters such as dust entering due to these parts operating unnecessarily. In addition, since the operation lever and the link mechanism are separated from the holder lock lever, the load of these parts does not act on the unlocking member such as an electromagnetic solenoid connected to the holder lock lever. It is possible to prevent an unnecessary load from acting on the member.

  Here, in the card reader / writer of the present invention, the link mechanism includes a first engagement portion and a second engagement portion formed on the operation lever, and the operation that moves from the first position toward the second position. A first engaged portion formed on the holder lock lever, and the card holder is inserted into the card so as to engage the first engagement portion of the lever and move the holder lock lever in the unlocking direction. A holder push-out member for pushing out toward the mouth and the second engagement portion of the operation lever that moves toward the second position after the holder lock lever is in the unlocked state, It can be set as the structure provided with the 2nd to-be-engaged part formed in the said holder pushing member so that pushing operation | movement of a card holder may be started.

  In this case, the first engaged portion of the holder lock lever is provided with a first engaged surface and a second engaged surface, and the first engaging portion of the operation lever is After the unlocked state is formed by engaging the first engaged surface and moving the holder lock lever in the unlocking direction, the first engaging portion is moved to the second engaged surface. It is desirable to engage and hold the holder lock lever in that position. In this way, the holder lock lever can be held in the unlocked state, and the holder lock lever can be prevented from moving more than necessary. When the holder lock member moves more than necessary, it is necessary to secure a space for it, which is disadvantageous in terms of downsizing and freedom of layout.

  An electromagnetic solenoid can be used as the unlocking member, and the holder lock lever may be urged in a direction to engage the card holder by the spring force of the return spring of the electromagnetic solenoid.

  In the card reader / writer of the present invention, the operation lever and the link mechanism of the card forced ejection mechanism are separated from the lock lever and the card holder. Normally, even if the lock lever and the card holder move, The link mechanism does not work. Therefore, according to the present invention, since members such as the operation lever of the card forced ejection mechanism do not operate during normal operation, it is possible to avoid problems such as intrusion of foreign matter caused by the unnecessary operation of these members. Further, it is possible to avoid the load of the operation lever and the link mechanism from acting on a lock releasing member such as an electromagnetic solenoid.

  An IC card reader / writer according to an embodiment of the present invention will be described below with reference to the drawings. Of course, the present invention can be similarly applied to a card reader / writer for handling a card-type storage medium such as a magnetic card other than an IC card.

  1 and 2 are diagrams showing the internal structure of an IC card reader / writer, FIG. 1 (a) is a schematic configuration diagram showing a state before an IC card is inserted, and FIG. FIG. 2 is a partial perspective view showing a part of the discharging mechanism, and FIG. 2 is a schematic configuration diagram showing a state after the IC card is inserted and pushed into the inside.

  Referring to these drawings, the IC card reader / writer 1 includes a flat, substantially rectangular case 2 in which each component is assembled. A card insertion slot 4 is formed in the front end surface 3 of the case 2. The front end surface portion where the card insertion slot 4 is formed has a concave central portion in the vertical direction so that the IC card 100 can be easily inserted and removed.

  Inside the case 2, a card holder 5 capable of receiving the IC card 100 inserted from the card insertion slot 4 is disposed. The card holder 5 is attached to the case 2 so as to be slidable in the front-rear direction in the case 2 from a card receiving position 5A on the front end side to a card pushing position 5B on the rear end side. A tension coil spring 6 extending horizontally in the front-rear direction is bridged between the card holder 5 and the case 2. When the IC card 100 is inserted from the card insertion slot 4, the card holder 5 can be pushed backward while the tension coil spring 6 is extended.

  A holder lock mechanism 7 for locking the card holder 5 to the card push-in position 5B is incorporated behind the card holder 5. The holder lock mechanism 7 includes a holder lock lever 9 that can pivot in the vertical direction about the support shaft 8 and an electromagnetic solenoid 10 that pivots the holder lock lever 9 up and down. An arm portion 9a on the front side of the support shaft 8 in the holder lock lever 9 extends forward along the side surface of the card holder 5, and a lever side engaging claw protruding downward and rearward on the lower end surface portion thereof. 9b is formed. On the side surface of the card holder 5, a holder side engagement claw 5 a is formed so that the lever side engagement claw 9 b can be engaged from the front side. The holder side engaging claw 5a is defined by a horizontal upper end surface 5b and an inclined front end surface 5c extending downward and rearward from the front end edge of the upper end surface 5b.

  Before the IC card 100 is inserted, the lever side engaging claw 9b of the holder lock lever 9 is pressed against the upper end surface 5b of the holder side engaging claw 5a by the return spring force of the electromagnetic solenoid 10 from above. 9A (state shown in FIG. 1). When the card holder 5 is pushed rearward, the lever side engaging claw 9b of the holder lock lever 9 is disengaged from the upper end surface 5b to the front side, and is engaged with the holder side engaging claw 5a from the front, and the card holder 5 is moved forward. Is in the locked state 9B in which the movement is blocked (the state shown in FIG. 2). When the electromagnetic solenoid 10 is excited, the holder lock lever 9 pivots upward and the locked state is released. As a result, the card holder 5 returns to the card receiving position 5A on the front end side by the spring force of the tension coil spring 6 (card discharge urging member).

  At the lower end portion of the front end surface 3 where the card insertion slot 4 is formed, a pull-out prevention shutter 11 is arranged. The pull-out prevention shutter 11 is for preventing the inserted IC card 100 from being accidentally pulled out. The pull-out prevention shutter 11 can turn in a case width direction (a direction perpendicular to the drawing) about a vertical shaft 11 a that is rotatably supported by the case 2. Further, the rear portion of the pull-out prevention shutter 11 with respect to the vertical shaft 11a is connected to an extension portion 5d extending forward from the front lower end portion of the card holder 5 via a cam mechanism (not shown). In a state where the card holder 5 is at the card receiving position 5 </ b> A, the front portion 11 b of the pull-out prevention shutter 11 with respect to the vertical shaft 11 a is retracted from the card insertion opening 4. When the card holder 5 is pushed down to the card push-in position 5B, the portion 11b protrudes into the card insertion slot 4 to block the card insertion slot 4, and the IC card 100 can be prevented from being pulled out.

  A card stopper 12 is disposed in the vicinity of the upper end side of the card insertion slot 4 inside the case 2. The card stopper 12 is attached to the case 2 so as to be pivotable in the vertical direction, and is biased downward by a torsion spring 13. A lower end surface portion of the card stopper 12 serves as a card pressing surface 12 a that can contact the upper end surface of the inserted IC card 100. The inserted IC card 100 is pressed by the card stopper 12 and is maintained in the state of being held by the card holder 5 without any play, and is pushed into the inside in this state.

  Note that the tip end portion 12b of the card stopper 12 pushed up by the inserted IC card 100 enters the detection position of the photosensor 14 disposed on the upper side thereof. The photo sensor 14 detects that the IC card 100 has been inserted. The holder lock lever 9 is formed with a detection piece 9c extending downward from the lower position of the support shaft 8. When the holder lock lever 9 is moved to the locked state 9B, the detection piece 9c is disengaged from the detection position of the photosensor 15 disposed below the support shaft 8, and thus the holder lock lever 9 is moved to the locked state 9B. That is, it is detected that the card holder 5 is pushed into the card pushing position 5B and locked there.

(Card forced ejection mechanism)
Here, when the inserted IC card 100 has a deformation such as a large warp, the inserted IC card 100 may be clogged inside. In this state, even if the holder lock mechanism 7 is released, the IC card 100 and the card holder 5 holding the IC card 100 are received by the card insertion slot 4 side only by the spring force of the tension coil spring 6. It may not be possible to return to position 5A. In addition, when the electromagnetic solenoid 10 of the holder lock mechanism 7 fails and does not operate, even when power supply to the electromagnetic solenoid 10 is stopped and the electromagnetic solenoid 10 is not driven, the IC card 100 can be released without being unlocked. In some cases, the held card holder 5 cannot be returned to the card receiving position 5A.

  In such a case, the IC card reader / writer 1 of this example includes a card forced ejection mechanism 20 for forcibly returning the card holder 5 to the card receiving position 5A and taking out the IC card 100. The card forced ejection mechanism 20 of this example is incorporated in a part above the rear end inside the case 2, and unlocking is performed to unlock the card holder 5 by the holder lock lever 9 when the operation lever 21 is operated. The operation and the holder pushing-out operation for pushing the unlocked card holder 5 forward are continuously performed.

  FIG. 3 is a schematic configuration diagram showing a state after the card holder 5 is unlocked by the card forced ejection mechanism 20. FIG. 4 is a schematic configuration diagram showing a state in which the card holder 5 after the lock is released by the card forced ejection mechanism 20 is pushed forward. The configuration and operation of the card forced ejection mechanism 20 will be described mainly with reference to FIGS. 1 (b), 3 and 4.

  The operation lever 21 of the card forced ejection mechanism 20 is disposed at a position above the rear end portion inside the case 2, and includes a first position 21A (see FIGS. 1 and 2) on the front side and a second position 21B on the rear side. It is attached to the case 2 so that it can slide between (refer FIG. 4). The operating lever 21 is always held at the first position 21A on the front side by a tension coil spring 22 (holding biasing member) spanned between here and the portion of the case 2 on the front side. . On the upper half portion of one side surface 21a of the operation lever 21, a finger hook portion 23 is formed which is composed of a plurality of uneven portions extending in the vertical direction. The finger hook 23 is exposed to the outside from the case 2, and the operator can place his / her finger on the finger hook 23 and slide the operation lever 21 to the second position 21 </ b> B hitting the rear end of the case. .

  The card forced ejection mechanism 20 transmits the movement of the operation lever 21 from the first position 21A to the second position 21B as a force that moves the holder lock lever 9 in the unlocking direction, and after the unlocking of the holder lock lever 9 is performed. A link mechanism that transmits the movement of the operation lever 21 as a force for pushing the card holder 5 toward the card insertion slot 4 is provided. The link mechanism of this example is configured as follows.

  First, a rectangular engagement protrusion 24 (first engagement portion) protrudes laterally from the lower half portion of one side surface 21a of the operation lever 21. Behind the engagement protrusion 24 is located the upper end portion 9d of the rear arm on the rear side of the support shaft 8 in the holder lock lever 9 in the unlocked state 9A (see FIG. 1). When the operation lever 21 is slid backward by a predetermined amount, the engaging protrusion 24 comes into contact with the front end surface portion 9e (first engaged surface) of the upper end portion 9d (first engaged portion). After the engagement protrusion 24 hits the front end surface portion 9e, the holder lock lever 9 is pushed rearward as the operation lever 21 is slid rearward, and pivots in the unlocking direction about the support shaft 8. Then, the lock of the card holder 5 is released.

  The engaging protrusion 24 rides on the upper end surface portion 9f (first engaged surface) after the upper end portion 9d of the holder lock lever 9 is pushed backward to shift to the unlocked state. FIG. 3 shows this state. Thereafter, it moves rearward along the upper end surface portion 9f. Therefore, the holder lock lever 9 is held in the unlocking posture 9C.

  Next, a holder push-out plate 25 is disposed at a portion of the operation lever 21 opposite to the side surface 21a. The holder push-out plate 25 is attached to the case 2 so as to be pivotable in the front-rear direction about the support shaft 26. A guide hole 25 a (second engaged portion) that is long in the front-rear direction is formed in a portion of the holder push-out plate 25 that is above the support shaft 26. An engagement pin 27 (second engagement portion) protrudes from the same position as the engagement protrusion 24 on the side surface of the operation lever 21 facing the guide hole 25a and is slidably inserted into the guide hole 25a. It is. On the other hand, an engagement arm 25 b that protrudes forward and downward is formed at a portion of the holder push-out plate 25 that is lower than the support shaft 26.

  Here, in a state where the operation lever 21 is in the first position 21 </ b> A on the front side, the engagement pin 27 hits the edge on the front end side in the guide hole 25 a of the holder push-out plate 25. Further, the lower engaging arm 25b of the holder push-out plate 25 is at a position where the tip can be brought into contact with the rear end surface 5e of the card holder 5 located at the card pushing position 5B. After the operation lever 21 is slid rearward and the engaging pin 27 hits the edge on the rear end side of the guide hole 25a of the holder push-out plate 25, the holder push-out plate 25 is interlocked with the slide of the operation lever 21. Is pushed rearward about the support shaft 26.

  In this example, as shown in FIG. 3, when the engaging protrusion 24 of the operation lever 21 rides on the upper end surface portion 9f of the holder lock lever 9, the engaging pin 27 is placed on the edge on the rear end side of the guide hole 25a. It is set to hit. Thereafter, in conjunction with the slide of the operation lever 21, the lower engaging arm 25b of the holder push-out plate 25 is pushed forward. As a result, the card holder 5 located at the card pushing position 5B is pushed forward by the engaging arm 25b. FIG. 4 shows this state. In this state, the end portion on the card insertion slot 4 side of the IC card 100 held by the card holder 5 protrudes from the card insertion slot 4 by a predetermined amount. Thus, the operator can hold the part with a finger and pull it out.

  As described above, the IC card reader / writer 1 of this example is equipped with the card forced ejection mechanism 20, and when the IC card 100 is clogged inside, the electromagnetic solenoid 10 breaks down and the card holder 5 is unlocked. In the case where the operation cannot be performed, the IC card 100 can be forcibly ejected by operating the operation lever 21 by hand.

  The operation lever 21 of the card forced ejection mechanism 20 can slide in the front-rear direction, but is normally held at the first position 21A on the front side by the tension coil spring 22. In this state, the engagement portion (engagement arm 25 b) with the card holder 5 in the link mechanism of the card forced ejection mechanism 20 is at a position outside the movement range of the card holder 5. That is, it is located on the rear side of the rear end face 5e of the card holder 5 located at the card pushing position 5B. Therefore, even if the card holder 5 moves with the insertion / removal of the IC card 100, the holder pushing plate 25 is not moved by the card holder 5, and the operation lever 21 is not moved.

  Further, the engagement protrusion 24 of the operation lever 21 that functions as an engagement portion with the holder lock lever 9 in the link mechanism is also at a position outside the movement range of the holder lock lever 9. Therefore, even if the holder lock lever 9 turns with the movement of the card holder 5, the upper end 9 d on the rear side does not hit the engagement protrusion 24 of the operation lever 21, so that the operation lever 21 may move. Absent.

  As described above, the operation lever 21 and the holder push-out plate 25 which are components of the card forced ejection mechanism 20 do not move when the normal IC card 100 is inserted and removed, and are separated from the card holder 5, and the holder lock mechanism. 7 are also separated from the holder lock lever 9 and the electromagnetic solenoid 10 which are the components of FIG. As a result, the operation lever 21 operates unnecessarily, and foreign matters such as dust enter the inside through the opening of the case 2 that exposes the operation lever 21 to the outside. The adverse effect of adhering to the portion of the support shaft 8 of the lever 9 etc. and hindering these smooth operations can be avoided. Further, it is possible to avoid the adverse effects such as the load of the operation lever 21 and the holder push-out plate 25 acting on the electromagnetic solenoid 10 to increase the driving load.

  In this example, as shown in FIGS. 3 and 4, after the holder lock lever 9 is in the unlocking posture 9C, the holder lock lever 9 is held in that state without further turning. Since the movement range of the holder lock lever 9 is suppressed and the space for the movement is reduced, the card reader / writer 1 is advantageous in terms of downsizing and layout flexibility.
