An actuator 35 has a switchover drive mechanism 46 which drives a switchover drive part 44 to shift in a right/left direction to switchover between a first transmission mode and a second transmission mode. Since the actuator 35 has only one rotation angle of θ on an input shaft 41 by means of an input shaft drive part 43, the rotation angle of the output shaft 42 is switched in two ways, i.e. an angle α and an angle β in the same time required for rotating the same.SELECTED DRAWING: Figure 7

Description

  The present invention relates to an actuator and a medium transaction apparatus, and is suitable for application to, for example, an automatic teller machine (ATM) that performs a desired transaction via a paper-like medium such as a banknote.

  Conventionally, as automatic teller machines used in financial institutions, etc., those that allow customers to deposit cash such as banknotes and coins and withdraw cash to customers according to the contents of transactions with customers are widely spread doing.

As an automatic teller machine, for example, a deposit / withdrawal unit that exchanges banknotes with customers, a transport unit that transports banknotes along a transport path, and a discrimination unit that discriminates the denomination, authenticity, etc. of banknotes Some have a temporary storage section that temporarily stores banknotes, a banknote storage that stores reusable banknotes for each denomination, and a reject storage that stores banknotes that should not be reused.
Is widely spread.

  The transport unit is provided with a switching unit that switches a plurality of transport paths in accordance with the banknote transport destination. For example, the switching unit includes a blade that guides banknotes between two selected transport paths and an actuator that rotates the blade while arranging the ends of the plurality of transport paths close to each other. It has become. This actuator can switch the banknote conveyance path, for example, by rotating a blade by a rotary solenoid.

  Moreover, in a switching part, a banknote may be conveyed along a 3 or more conveyance path by rotating a braid | blade so that it may become 3 or more angles. However, a simple solenoid can only turn the blade at two angles. Therefore, in the switching unit, the blade is rotated in two ways by the first solenoid, and the blade and the first solenoid are collectively rotated by the second solenoid, resulting in three or more blades as a result. A device that is rotated to an angle has been proposed (see, for example, Patent Document 1).

  On the other hand, in an automatic teller machine, since it is desirable to complete a deposit transaction and a withdrawal transaction in a short time, banknotes are continuously conveyed at a high speed in a conveyance unit. Along with this, the switching unit needs to switch the blades at high speed according to the banknote transport destination.

However, in the above-described actuator of the switching unit, for example, the rotation by the first solenoid having a small rotation angle can be performed in a short time, while the rotation by the second solenoid having a large rotation angle requires a long time. There is a case. For this reason, the automatic teller machine has a problem that it takes time to switch the conveyance path in the switching unit, and as a result, the deposit transaction and the withdrawal transaction may not be completed in a short time.

  The present invention has been made in consideration of the above points, and intends to propose an actuator and a medium transaction apparatus that can be rotated in a short time regardless of the size of the angle.

  In order to solve such a problem, in the actuator of the present invention, an input shaft that rotates around a predetermined input center line, and the input shaft rotates from one to the other at two rotation angles in a predetermined rotation time. A rotation unit that rotates, an output shaft that rotates around an output center line parallel to the input center line, and transmits rotation of the input shaft to the output shaft, as well as rotation angle of the input shaft and rotation of the output shaft A switching transmission unit that switches a plurality of reduction ratios, which are ratios to angles, is provided.

  Moreover, in the medium transaction apparatus of this invention, it is a medium transaction apparatus which trades a medium between users, Comprising: The conveyance guide which guides a medium along a predetermined | prescribed conveyance path, and three or more conveyance paths cross | intersect. A blade that guides the medium in the direction in which the medium should travel, an input shaft that rotates about a predetermined input center line, and an input shaft from one to the other at two rotation angles in a predetermined rotation time. By rotating around a rotating part that rotates, and an output center line parallel to the input center line, the output shaft that rotates the blade, and the rotation of the input shaft are transmitted to the output shaft, and the input shaft And a switching transmission portion for switching a plurality of reduction ratios, which is a ratio of the rotation angle of the output shaft to the rotation angle of the output shaft.

  In the present invention, since the switching transmission unit switches the reduction ratio to a plurality and transmits the rotation from the input shaft to the output shaft, the rotation unit simply rotates the input shaft in a predetermined rotation time. The output shaft can be rotated to different rotation angles while maintaining the time.

  Thus, the banknote depositing / dispensing machine 10 switches the banknote transport path among the first transport section 21, the temporary storage section 15, and the second transport section 22 by the temporary storage switching section 20 of the transport section 13. Yes.

[1-2. Configuration of temporary hold switching unit]
Next, the configuration of the temporary hold switching unit 20 will be described. As shown in the schematic left side view of FIG. 4, the temporary holding switching unit 20 includes a plurality of conveyance guides 31, a plurality of rollers 32, a rotation shaft 33, a plurality of blades 34, and an actuator 35. It is configured.

  The conveyance guide 31 forms three conveyance paths that are continuous with the conveyance guides of the first conveyance unit 21 (FIG. 3), the temporary storage unit 15 (FIG. 2), and the second conveyance unit 22 (FIG. 3). The banknotes are guided along this transport path. In each roller 32, a plurality of short columnar members whose center axes are directed in the left-right direction are arranged at locations separated from each other in the left-right direction. The rollers 32 are arranged on both sides of each conveyance path, and are in contact with the other roller 32 opposed across the conveyance path in the conveyance path. The roller 32 rotates when a driving force is transmitted from a motor (not shown). When a bill is sandwiched between the roller 32 and the other roller 32, the roller 32 transmits the driving force to the bill and follows the conveyance path. Can be advanced.

  The rotation shaft 33 is formed in an elongated cylindrical shape with the central axis directed in the left-right direction, and is rotatably supported by a bearing (not shown). As shown in a schematic plan view in FIG. 5, the blade 34 is a thin plate in the left-right direction, and is formed in an isosceles triangle or wedge shape having a relatively narrow apex angle when viewed from the left-right direction (FIG. 3). ). The blades 34 are sequentially passed through the rotation shaft 33 with their directions aligned, and are spaced apart from each other in the left-right direction. Hereinafter, the direction in which the apex angle of the blade 34 with respect to the rotation shaft 33 faces is regarded as the direction of the blade 34.

  Incidentally, in the temporary hold switching unit 20, the positions in the left and right directions are adjusted so that the rollers 32 and the blades 34 do not interfere with each other. In addition, slits and holes are appropriately formed in the conveyance guide 31 so as not to interfere with the blade 34 and the roller 32. The actuator 35 has an output shaft connected to the rotation shaft 33, and rotates the output shaft and the rotation shaft 33 based on the control of the bill control unit 11 (details will be described later).

  Here, the conveyance direction of the banknotes in the temporary hold switching unit 20 depends on the configuration of the conveyance guide 31 and the blade 34, and as shown in FIG. 6, there are six conveyance paths W1, W2, and W3 according to the direction of the blade 34. , W4, W5 and W6. However, the actual temporary hold switching unit 20 can rotate the blade 34 only in some of the six directions shown in FIG.

[1-3. Actuator configuration]
The actuator 35 is roughly divided into an input shaft 41, an output shaft 42, a perspective view shown in FIG. 7, and a plan view shown in FIGS. 8A and 8B and FIGS. 9A and 9B. The input shaft rotating unit 43, the switching moving unit 44, the output transmitting unit 45, and the switching driving unit 46 are configured. These components are incorporated in a housing 40 (FIG. 5) configured in a hollow box shape. For convenience of explanation, the switching movement unit 44, the output transmission unit 45, and the switching drive unit 46 are also collectively referred to as a switching transmission unit 47 below. 8A and 8B and FIGS. 9A and 9B show a left side view and a front view side by side, respectively.

  The input shaft 41 is formed in a cylindrical shape centered on a virtual input center line 41C along the left-right direction, and can be rotated around the input center line 41C by the housing 40 (FIG. 5). So that it is supported. Further, the input shaft 41 has a flat portion 41 </ b> A formed by cutting the vicinity of the upper end in the range of about half on the left side. For convenience of explanation, the rotation angle about the input center line 41C described above is regarded as the rotation angle of the input shaft 41 below.

  Similarly to the input shaft 41, the output shaft 42 is formed in a columnar shape centered on a virtual output center line 42C along the left-right direction. This output center line is also formed by the housing 40 (FIG. 5). It is supported so that it can rotate around 42C. For convenience of explanation, hereinafter, an angle when the output center line 42C is rotated as a center is regarded as a rotation angle of the output shaft 42. Further, the output shaft 42 is connected to the rotating shaft 33 described above by projecting the vicinity of the left end from the hole formed in the housing 40 to the outside of the housing 40 (FIG. 5).

  The input shaft rotating unit 43 includes a so-called rotary solenoid including the electromagnetic coil 51, the iron core 52, the armature plate 53, and the permanent magnets 54 and 55. The electromagnetic coil 51 is wound with an electric wire so as to circulate around a virtual central axis along the left-right direction, and connects the input shaft 41 and the output shaft 42 in the vertical direction to the inner wall of the housing 40. It is fixed so that it lies on a virtual straight line. The electromagnetic coil 51 generates an N-pole or S-pole magnetic force on the left side surface of the electric wire after a polarity is set to the electric wire and a current is supplied thereto. The iron core 52 is made of iron, which is a magnetic material, and is inserted through the center of the electromagnetic coil 51.

  The amateur plate 53 is thin in the left-right direction and is formed in a bell-shaped plate shape when viewed from the left-right direction. The armature plate 53 is fixed to the input shaft 41 by inserting the input shaft 41 through a hole formed in the vicinity of the upper end. Further, permanent magnets 54 and 55 are embedded in the right surface of the amateur plate 53 at two locations separated in the front-rear direction. The permanent magnet 54 is formed in a thin rectangular parallelepiped shape in the left-right direction, and the right side surface is an S pole. On the other hand, the permanent magnet 55 is formed in a rectangular parallelepiped shape similar to the permanent magnet 54, and the right side surface is an N pole.

  With this configuration, the input shaft rotating unit 43 generates N-pole magnetic force on the left side surface when, for example, current is supplied to the electromagnetic coil 51 with a predetermined polarity. As a result, the electromagnetic coil 51 repels the permanent magnet 55 having the N-pole on the right side and pulls the permanent magnet 54 having the S-pole on the right side to rotate the input shaft 41 and the armature plate 53 together.

  Eventually, the input shaft rotating unit 43 stops the input shaft 41 at an angle at which the permanent magnet 54 is closest to the electromagnetic coil 51, as shown in FIG. Hereinafter, this state is referred to as a first input state. Incidentally, when the supply of current to the electromagnetic coil 51 is interrupted, the input shaft rotating unit 43 can maintain the first input state as it is because an attractive force acts between the permanent magnet 54 and the iron core 52.

  Further, the input shaft rotating unit 43 generates an S-pole magnetic force on the left side surface when a current is supplied to the electromagnetic coil 51 with the opposite polarity. As a result, the electromagnetic coil 51 repels the permanent magnet 54 having the right side surface as the S pole, while attracting the permanent magnet 55 having the right side surface as the N pole, and rotates the input shaft 41 and the armature plate 53 together.

  Eventually, the input shaft rotating unit 43 stops the input shaft 41 at an angle at which the permanent magnet 55 is closest to the electromagnetic coil 51, as shown in FIG. 8B. Hereinafter, this state is referred to as a second input state. Incidentally, when the supply of current to the electromagnetic coil 51 is interrupted, the input shaft rotating unit 43 can maintain the second input state as it is because an attractive force acts between the permanent magnet 55 and the iron core 52 this time.

  The switching moving unit 44 includes an insertion unit 61, an input transmission arm unit 62, a first transmission projection 63, and a second transmission projection 64. The insertion portion 61 is formed in a cylindrical shape with the central axis directed in the left-right direction, and the outer diameter is slightly larger than the outer diameter of the input shaft 41. The insertion portion 61 is provided with a through hole 61H penetrating in the left-right direction. The through hole 61H has a round hole shape that is slightly larger than the outer diameter of the input shaft 41, and a flat planar portion 61HA is formed at a location corresponding to the planar portion 41A.

  For this reason, the insertion portion 61 can move in the left-right direction along the input shaft 41 when the through hole 61H is inserted on the left side of the input shaft 41. Here, the insertion part 61 is restricted from rotating or rotating around the input center line 41C due to interference between the flat part 61HA and the flat part 41A, and therefore can only move in the left-right direction with respect to the input shaft 41. Become. In other words, the insertion portion 61 is rotated together with the input shaft 41 by the input shaft rotating portion 43.

  The input transmission arm portion 62 is formed in a rectangular parallelepiped shape or a thin plate shape that is thin in the left-right direction and long in the up-down direction, and its upper end is fixed to the lower surface of the insertion portion 61. For this reason, the input transmission arm portion 62 moves in the left-right direction together with the insertion portion 61 with respect to the input shaft 41 and rotates together with the input shaft 41.

  The first transmission protrusion 63 is formed in a small cylindrical shape with the central axis directed in the left-right direction, and is erected on the right side surface of the input transmission arm portion 62 toward the right direction. Similar to the first transmission protrusion 63, the second transmission protrusion 64 is formed in a small cylindrical shape with the central axis directed in the left-right direction, and is erected on the left side surface of the input transmission arm 62 toward the left direction. ing. That is, the first transmission protrusion 63 and the second transmission protrusion 64 have shapes that protrude in the right direction and the left direction from the periphery on the right side surface and the left side surface of the input transmission arm portion 62, respectively.

  Further, the distance from the central axis of the input shaft 41 to the second transmission protrusion 64 is different from the distance from the central axis of the input shaft 41 to the first transmission protrusion 63. Incidentally, the second transmission protrusion 64 is provided in the same radial direction as the first transmission protrusion 63 with the input center line 41C of the input shaft 41 as a reference.

  The output transmission unit 45 includes a first output transmission body 71 and a second output transmission body 72. Like the input transmission arm portion 62, the first output transmission body 71 is formed in a thin and long rectangular parallelepiped shape or a thin plate shape in the left-right direction, and one end in the longitudinal direction is fixed to the output shaft 42. A first transmission hole 71 </ b> H is formed in the vicinity of the outer end, which is the end of the first output transmission body 71 opposite to the output shaft 42. The first transmission hole 71H penetrates the first output transmission body 71 in the left-right direction, and is a long hole along the radial direction centered on the output center line 42C.

  Similarly to the first output transmission body 71, the second output transmission body 72 is formed in a thin and long rectangular parallelepiped shape or a thin plate shape in the left-right direction, and one end in the longitudinal direction with respect to the output shaft 42 is the first output transmission body 71. It is fixed at a location slightly away from the left side. The second output transmission body 72 is fixed to the output shaft 42 on the left side of the first output transmission body 71, and the longitudinal direction of the second output transmission body 72 is different from that of the first output transmission body 71 with respect to the output center line 42C. Directed in the radial direction. In the vicinity of the outer end of the second output transmission body 72, a second transmission hole 72H is formed. Similarly to the first transmission hole 71H, the second transmission hole 72H penetrates the second output transmission body 72 in the left-right direction, and is a long hole along the radial direction centering on the output center line 42C.

  Incidentally, as shown in FIG. 8A and FIG. 9A, the first output transmission body 71 and the second output transmission body 72 are input transmission arm portions when the input shaft 41 is in the first input state. The mounting angle with respect to the output shaft 42 is adjusted so that the positions of the first transmission hole 71H and the second transmission hole 72H are aligned with the first transmission protrusion 63 and the second transmission protrusion 64 of 62, respectively.

  The switching drive unit 46 as a transmission ratio switching unit includes an electromagnetic coil 81, an iron core 82, a permanent magnet 83, and a spring 84. As with the electromagnetic coil 51 of the input shaft rotating unit 43, the electromagnetic coil 81 is wound with an electric wire so as to circulate around a virtual central axis along the left-right direction, and the casing 40 (FIG. 5). It is fixed to the inner wall. Similar to the iron core 52, the iron core 82 is made of iron, which is a magnetic material, and is inserted through the center of the electromagnetic coil 81. The permanent magnet 83 is fixed to the left side surface of the input transmission arm unit 62 of the switching moving unit 44, and a predetermined magnetic pole (for example, N pole) is directed to the left side.

  The spring 84 is a coil spring, the inner diameter thereof is larger than the outer diameter of the input shaft 41, and is wound spirally with the central axis directed in the left-right direction. The spring 84 is inserted into the input shaft 41 in a compressed state from the natural length, the left end thereof is brought into contact with the inner surface of the housing 40, and the right end thereof is the left side surface of the insertion portion 61 of the switching moving unit 44. It is made to contact.

  With this configuration, for example, when the current is supplied to the electromagnetic coil 81 with a predetermined polarity, the switching drive unit 46 generates an N-pole magnetic force on the right side surface. At this time, as shown in FIG. 8A, the switching moving portion 44 is pushed rightward by a permanent magnet 83 fixed to the input transmission arm portion 62 and facing the N pole on the left side. Here, the switching moving portion 44 inserts the first transmission protrusion 63 into the first transmission hole 71H of the first output transmission body 71 when the output shaft 42 has a predetermined rotation angle. Incidentally, even if the current supply to the electromagnetic coil 81 is interrupted in this state, the switching drive unit 46 can maintain the state in which the switching moving unit 44 is pressed to the right side by the restoring force of the spring 84.

  Accordingly, when the input shaft 41 is rotated by the input shaft rotating portion 43, the actuator 35 transmits the force from the first transmission protrusion 63 of the input transmission arm portion 62 to the first transmission hole 71 </ b> H of the first output transmission body 71. By transmitting to the output shaft 42, the output shaft 42 can be rotated as shown in FIG. That is, the actuator 35 forms a so-called link mechanism by the input transmission arm portion 62 and the first output transmission body 71. Hereinafter, the state in which the first transmission protrusion 63 is inserted through the first transmission hole 71H in this way is also referred to as a first transmission state.

  In addition, for example, when the current is supplied to the electromagnetic coil 81 with the opposite polarity to the above, the switching drive unit 46 generates the S pole magnetic force on the right side surface. At this time, as shown in FIG. 9A, the switching moving portion 44 is attracted to the left by a permanent magnet 83 fixed to the input transmission arm portion 62 and facing the N pole on the left side. Here, the switching moving portion 44 inserts the second transmission protrusion 64 into the second transmission hole 72H of the second output transmission body 72 when the output shaft 42 has a predetermined rotation angle. Incidentally, even if the current supply to the electromagnetic coil 81 is interrupted in this state, the switching drive unit 46 can keep the switching moving unit 44 pulled to the left side because the permanent magnet 83 is continuously pulled by the iron core 82.

  Thereby, when the input shaft 41 is rotated by the input shaft rotating portion 43, the actuator 35 transmits the force from the second transmission protrusion 64 of the input transmission arm portion 62 to the second transmission hole 72 </ b> H of the second output transmission body 72. As shown in FIG. 9B, the output shaft 42 can be rotated. That is, in this case, the actuator 35 forms a link mechanism by the input transmission arm portion 62 and the second output transmission body 72. Hereinafter, the state in which the second transmission protrusion 64 is inserted through the second transmission hole 72H is also referred to as a second transmission state.

  In this way, the actuator 35 moves the switching moving unit 44 in the left-right direction along the input shaft 41 by the switching drive unit 46, thereby causing the first transmission state (FIG. 8A) or the second transmission state (FIG. 9 ( After switching to A)), a force for rotating the input shaft 41 by the input shaft rotating portion 43 is transmitted to the output shaft 42 and rotated.

[1-4. Output shaft rotation angle and switching]
Next, the rotation angle of the output shaft 42 in the actuator 35 and switching thereof will be described with reference to FIGS. 10 (A) and 10 (B) and FIGS. 11 (A) and 11 (B). 10A and 10B show the input shaft 41, the input transmission arm 62, the first transmission protrusion 63, the first output transmission body 71, and the output shaft 42 in FIGS. 8A and 8B. It is the extracted left view. 11A and 11B extract the input shaft 41, the input transmission arm 62, the second transmission protrusion 64, the second output transmission body 72, and the output shaft 42 in FIGS. 9A and 9B. FIG.

  As described above, the input shaft 41 of the actuator 35 is rotated by the input shaft rotating unit 43 (FIG. 7). Due to its structure, the input shaft rotating unit 43 rotates the input shaft 41 and the armature plate 53 only in the first input state (FIG. 8A) or the second input state (FIG. 8B). Can not be rotated to other angles.

  Here, as shown in FIG. 10A, an imaginary straight line 35X connecting the centers of the input shaft 41 and the output shaft 42 is defined, and the input center line 41C of the input shaft 41 and the first transmission protrusion 63 are defined. A virtual straight line 63X along the input transmission arm 62 connecting the centers, and a virtual straight line 71X along the first output transmission body 71 connecting the output center line 42C of the output shaft 42 and the center of the first transmission protrusion 63. Define In this case, the center of the first transmission protrusion 63 can be regarded as a transmission point for transmitting force from the input transmission arm 62 to the first output transmission body 71. Furthermore, the ratio of the length of the straight line 63X and the straight line 71X is K: L.

  In addition, a virtual straight line obtained by extending the straight line 35X downward is defined as a reference line 35B, and the first input state (FIG. 10 (A) in the virtual straight line directed outward from the center of the output shaft 42 is defined. ) And FIG. 11A), an arrow pointing in a direction overlapping with the reference line 35B is defined as a virtual arrow 42X, and the state of the output shaft 42 at this time is also referred to as an initial output state. To do. The virtual arrow 42X rotates with the output shaft 42. For this reason, the angle formed by the virtual arrow 42X with respect to the reference line 35B represents the rotation angle of the output shaft 42 from the initial output state.

  In the first transmission state in which the first transmission protrusion 63 is inserted through the first transmission hole 71H, the actuator 35 moves the input shaft 41 from the first input state to the second input state by the input shaft rotating portion 43 (FIG. 7). By rotating, the output shaft 42 is rotated, and the state shown in FIG. 10B corresponding to FIG. Here, when the rotation angle of the input shaft 41 is an angle θ and the rotation angle of the output shaft 42 is an angle α, the angle α can be expressed as follows by using the ratio K: L and the angle θ described above ( 1) It can be expressed as:

  α = (K / L) θ (1)

  Here, the coefficient (K / L) is a reduction ratio when the rotation is transmitted from the input shaft 41 to the output shaft 42 via the switching transmission unit 47 (the switching moving unit 44, the output transmission unit 45, and the switching driving unit 46). Is a value representing.

  Next, as shown in FIG. 11A, in addition to the straight line 35X, an imaginary straight line 64X along the input transmission arm portion 62 connecting the input center line 41C of the input shaft 41 and the center of the second transmission projection 64. And an imaginary straight line 72X along the second output transmission body 72 connecting the output center line 42C of the output shaft 42 and the center of the second transmission projection 64 is defined. Also in this case, the center of the second transmission protrusion 64 can be regarded as a transmission point for transmitting force from the input transmission arm portion 62 to the second output transmission body 72. Furthermore, the ratio of the length of the straight line 64X and the straight line 72X is M: N.

  In the second transmission state in which the second transmission protrusion 64 is inserted through the second transmission hole 72H, the actuator 35 causes the input shaft 41 to move from the first input state to the second input state by the input shaft rotating portion 43 (FIG. 7). By rotating, the output shaft 42 is rotated, and the state shown in FIG. 11B corresponding to FIG. Here, when the rotation angle of the input shaft 41 is an angle θ and the rotation angle of the output shaft 42 is an angle β, the angle β can be expressed as follows by using the ratio M: N and the angle θ described above ( 2) It can be expressed as:

  β = (M / N) θ (2)

  8 to 11, in the actuator 35, the straight line 64X is longer than the straight line 63X, and the straight line 72X is shorter than the straight line 71X. For this reason, in the actuator 35, the value (M / N) is larger than the value (K / L) representing each reduction ratio. That is, in the actuator 35, the angle β is larger than the angle α.

  In other words, the actuator 35 has a reduction ratio when the rotation is transmitted from the input shaft 41 to the output shaft 42 via the switching transmission unit 47 (the switching movement unit 44, the output transmission unit 45, and the switching driving unit 46). It can be switched to (K / L) or (M / N).

  Further, when the rotation angle of the output shaft 42 in the actuator 35 is arranged according to the angle of the input shaft 41 (first input state or second input state) and the position (right side or left side) of the switching moving unit 44, FIG. It can be expressed as a state transition diagram. In the drawing, bold rectangles represent individual states, and the values in them represent the rotation angle of the output shaft 42. Incidentally, the value “0” means that the output shaft 42 is in the initial output state (FIG. 10A, etc.).

  Thus, as can be seen from FIG. 12, the actuator 35 has the switching drive unit 46 in spite of the fact that the rotation angle of the input shaft 41 by the input shaft rotation unit 43 (FIG. 7) is one angle θ. By switching to the first transmission state (FIG. 8) or the second transmission state (FIG. 9), the rotation angle of the output shaft 42 can be switched to the angle α (FIG. 10) or the angle β (FIG. 11).

[1-5. Operation and effect]
In the above configuration, the banknote depositing / dispensing machine 10 of the automatic teller machine 1 according to the first embodiment is switched by the switching drive unit 46 in the actuator 35 that constitutes the temporary holding switching unit 20 of the transport unit 13. Is moved to the first transmission state (FIG. 8) or the second transmission state (FIG. 9) having different reduction ratios. As a result, the actuator 35 changes the rotation angle of the output shaft 42 to the angle α and the angle even though the rotation angle of the input shaft 41 by the input shaft rotation unit 43 (FIG. 7) is only one angle θ. It is possible to switch between two types of β.

  At this time, since the rotation angle of the input shaft 41 is one angle θ, the actuator 35 has the input shaft rotation portion 43 regardless of the rotation angle of the output shaft 42, either the angle α or the angle β. The time required for rotation of the input shaft 41 is constant. As a result, the actuator 35, for example, rotates the blade 34 between the sixth angle (FIG. 6F) and the fifth angle (FIG. 6E), and the sixth angle and the third angle (FIG. 6). 6 (C)), the rotation can be completed in an equivalent time.

  In other words, in the actuator 35, the rotation means of the input shaft 41 is a single input shaft rotation portion 43, and the rotation angle is fixed at the angle θ. Even if the force transmission path to the shaft 42 is switched in the switching transmission unit 47 and the rotation angle of the output shaft 42 is switched, the time required for the rotation can be maintained substantially constant.

  According to the above configuration, the banknote depositing / dispensing machine 10 of the automatic teller machine 1 according to the first embodiment causes the switching drive unit 46 to move the switching moving unit 44 in the left-right direction in the actuator 35 to perform the first transmission. Switch to the state (FIG. 8) or the second transmission state (FIG. 9). At this time, since the rotation angle of the input shaft 41 by the input shaft rotation unit 43 is one angle θ, the actuator 35 is able to switch the rotation angle of the output shaft 42 between two angles α and β. The time required for the rotation can be kept equal.

[2. Second Embodiment]
The automatic teller machine 101 (FIG. 1) by 2nd Embodiment has the banknote depositing / withdrawing machine 110 replaced with the banknote depositing / withdrawing machine 10 compared with the automatic teller machine 1 by 1st Embodiment. However, the other points are configured in the same manner. The banknote depositing / dispensing machine 110 (FIG. 2) is different from the banknote depositing / dispensing machine 10 in that it includes a transport unit 113 instead of the transport unit 13, but is configured in the same manner for other points.

  The transport unit 113 (FIG. 3) is different from the transport unit 13 in that it has a temporary hold switching unit 120 instead of the temporary hold switch unit 20, but is configured similarly in other points. The temporary hold switching unit 120 (FIGS. 4 and 5) differs from the temporary hold switching unit 20 in that it includes an actuator 135 that replaces the actuator 35, but is configured similarly in other respects.

  As shown in FIGS. 13 and 14 corresponding to FIGS. 8 and 9, the actuator 135 includes a switching movement unit 144 and an output transmission unit 145 instead of the switching movement unit 44 and the output transmission unit 45, as compared with the actuator 35. Although it differs in the point which has, it is comprised similarly about another point. In FIG. 12 and FIG. 13, the switching drive unit 46 is omitted.

  The switching moving part 144 includes an insertion part 61 similar to the switching moving part 44, a first input transmission body 163 and a second input transmission body in place of the input transmission arm part 62, the first transmission protrusion 63, and the second transmission protrusion 64. 164. Although the first input transmission body 163 is formed in a thin plate shape in the left-right direction, unlike the input transmission arm portion 62 (FIG. 7 and the like), the first input transmission body 163 is formed in a sector shape centered on the central axis of the input shaft 41. Yes. A tooth mold 163G is formed on the arc portion of the first input transmission body 163. That is, the first input transmission body 163 has a shape in which a part of a gear having a tooth shape formed on the peripheral side portion of the disk is cut out in a fan shape. For convenience of illustration, in FIG. 13 and the like, the tooth mold 163G and the like are simplified and represented as simple arcs.

  Similarly to the first input transmission body 163, the second input transmission body 164 is formed in a sector shape centered on the central axis of the input shaft 41, and is disposed adjacent to the right side of the first input transmission body 163. ing. However, the second input transmission body 164 has a fan-shaped radius smaller than that of the first input transmission body 163. A tooth mold 164G is also formed in the arc portion of the second input transmission body 164.

  The output transmission unit 145 includes a first output transmission body 171 and a second output transmission body 172 instead of the first output transmission body 71 and the second output transmission body 72. The 1st output transmission body 171 is attached to the output shaft 42, and is formed in the fan-shaped plate shape which reversed the 1st input transmission body 163 up and down. Further, a tooth mold 171G is formed on the arc portion of the first output transmission body 171 as in the case of the first input transmission body 163.

  The radius of the fan-shaped portion of the first output transmission body 171 is calculated from the length of a virtual straight line 35X (FIG. 10 and the like) connecting the input center line 41C of the input shaft 41 and the output center line 42C of the output shaft 42. This corresponds to the length obtained by subtracting the radius of the fan-shaped portion of the input transmission body 163. For this reason, as shown in FIG. 13A, the first output transmission body 171 is provided in the first input transmission body 163 of the switching moving portion 144 when the switching moving portion 144 is moved to the left side. The tooth mold 163G and the tooth mold 171G of the first output transmission body 171 can be engaged with each other.

  Thereby, when the input shaft 41 is rotated by the input shaft rotating portion 43, the actuator 135 transmits the force from the tooth mold 163G of the first input transmission body 163 to the tooth mold 171G of the first output transmission body 171. As a result, the output shaft 42 can be rotated to the state shown in FIG. Hereinafter, the state in which the tooth mold 163G of the first input transmission body 163 is meshed with the tooth mold 171G of the first output transmission body 171 is also referred to as a first transmission state in this embodiment.

  Further, the ratio between the radius of the sector portion in the first input transmission body 163 and the radius of the sector portion in the first output transmission body 171 is the ratio of the lengths of the straight line 63X and the straight line 71X in the first embodiment (see FIG. 10: (A)), K: L. Therefore, in the actuator 135, as in the first embodiment, the relationship between the angle θ, which is the rotation angle of the input shaft 41, and the angle α, which is the rotation angle of the output shaft 42, is the expression (1) described above. Can be represented by

  The second output transmission body 172 is attached to the left side of the first output transmission body 171 with respect to the output shaft 42, and is formed in a fan-like plate shape like the first output transmission body 171. Yes. In addition, a tooth mold 172G is formed in the arc portion of the second output transmission body 172, similarly to the first output transmission body 171.

  The radius of the fan-shaped portion in the second output transmission body 172 corresponds to the length obtained by subtracting the radius of the fan-shaped portion in the second input transmission body 164 from the length of the virtual straight line 35X. Therefore, as shown in FIG. 14A, the second output transmission body 172 is provided in the second input transmission body 164 of the switching movement section 144 when the switching movement section 144 is moved to the right side. The tooth mold 164G and the tooth mold 172G of the second output transmission body 172 can be engaged with each other.

  Thus, when the input shaft 41 is rotated by the input shaft rotating portion 43, the actuator 135 transmits the force from the tooth mold 164G of the second input transmission body 164 to the tooth mold 172G of the second output transmission body 172. As a result, the output shaft 42 can be rotated to the state shown in FIG. Hereinafter, the state in which the tooth mold 164G of the second input transmission body 164 is meshed with the tooth mold 172G of the second output transmission body 172 is also referred to as a second transmission state in this embodiment.

  Further, the ratio between the radius of the sector portion in the second input transmission body 164 and the radius of the sector portion in the second output transmission body 172 is the ratio of the lengths of the straight line 64X and the straight line 72X in the first embodiment (see FIG. 11 (A)), M: N. Therefore, in the actuator 135, as in the first embodiment, the relationship between the angle θ, which is the rotation angle of the input shaft 41, and the angle β, which is the rotation angle of the output shaft 42, is expressed by the equation (2) described above. Can be represented by

  In the above configuration, the actuator 135 in the banknote depositing / dispensing machine 110 of the automatic teller machine 101 according to the second embodiment causes the switching drive unit 46 to move the switching moving unit 44 in the left-right direction, thereby reducing the mutual reduction ratio. Are switched to the first transmission state (FIG. 13) or the second transmission state (FIG. 14). As a result, the actuator 135 has the output shaft 42 in spite of the fact that the rotation angle of the input shaft 41 by the input shaft rotation unit 43 (FIG. 7) is only one angle θ, as in the first embodiment. Can be switched between two angles α and β.

  At this time, similarly to the first embodiment, the actuator 135 can maintain the time required for the rotation substantially constant even if the rotation angle of the output shaft 42 is switched to the angle α or the angle β.

  According to the above configuration, the banknote depositing / dispensing machine 110 of the automatic teller machine 101 according to the second embodiment causes the switching driving unit 46 to move the switching moving unit 44 in the left-right direction in the actuator 135 to perform the first transmission. Switch to the state (FIG. 13) or the second transmission state (FIG. 14). At this time, since the actuator 135 rotates the input shaft 41 by the input shaft rotating unit 43 at one angle θ, the actuator 135 can switch the rotation angle of the output shaft 42 between two angles α and β. The time required for the rotation can be kept equal.

[3. Third Embodiment]
Compared with the automatic teller machine 1 according to the first embodiment, the automatic teller machine 201 according to the third embodiment has a banknote depositing and dispensing machine 210 that replaces the banknote depositing and dispensing machine 10. However, the other points are configured in the same manner. The banknote depositing / dispensing machine 210 (FIG. 2) is different from the banknote depositing / dispensing machine 10 in that it includes a transport unit 213 that replaces the transport unit 13, but is configured similarly in other respects.

  The transport unit 213 (FIG. 3) is different from the transport unit 13 in that it includes a temporary hold switching unit 220 instead of the temporary hold switch unit 20, but is configured in the same manner for other points. The temporary hold switching unit 220 (FIGS. 4 and 5) is different from the temporary hold switching unit 20 in that it has an actuator 235 that replaces the actuator 35, but is configured in the same manner for other points.

  As shown in FIG. 15 corresponding to FIG. 7, the actuator 235 is different from the actuator 35 in that it has an output transmission unit 245 instead of the output transmission unit 45, but is configured similarly in other points. ing. Hereinafter, the switching moving unit 44, the output transmission unit 245, and the switching driving unit 46 are collectively referred to as a switching transmission unit 247. The output transmission unit 245 is different from the output transmission unit 45 in that a third output transmission body 273 is added, but the first output transmission body 71 and the second output transmission body 72 are similarly configured. Has been.

  Like the first output transmission body 71, the third output transmission body 273 is formed in a thin and long rectangular parallelepiped shape or a thin plate shape in the left-right direction, and in the state adjacent to the left side of the first output transmission body 71, the output shaft One end in the longitudinal direction is fixed to 42. A third transmission hole 273H similar to the first transmission hole 71H is formed in the vicinity of the outer end of the third output transmission body 273. The third output transmission body 273 has its longitudinal direction oriented in a radial direction different from any of the first output transmission body 71 and the second output transmission body 72 with respect to the output center line 42C.

  With this configuration, when the input shaft 41 is in the first input state, the output shaft 42 is in the initial output state, and the switching driving unit 46 moves the switching moving unit 44 to the right by the configuration, the actuator 235 Similarly to the embodiment, the first transmission protrusion 63 is inserted into the first transmission hole 71H of the first output transmission body 71 (FIG. 8). Therefore, the actuator 235 can rotate the output shaft 42 by the angle α when the input shaft 41 is rotated from the first input state to the second input state by the input shaft rotating portion 43 (FIG. 10). .

  Further, as shown in FIG. 16 corresponding to FIG. 9, the actuator 235 has the input shaft 41 in the first input state, the output shaft 42 in the initial output state, and the switching drive unit 46 moves the switching moving unit 44 to the left. When the second transmission protrusion 64 is inserted into the second transmission hole 72H of the second output transmission body 72, the second transmission state is achieved as in the first embodiment. Therefore, the actuator 235 rotates the output shaft 42 by an angle β when the input shaft 41 is rotated from the first input state to the second input state by the input shaft rotating portion 43 as shown in FIG. Can be made.

  Here, as shown in FIG. 16B, the actuator 235 performs the first transmission when the input shaft 41 is in the second input state and the output shaft 42 is rotated by an angle β from the initial output state. The mounting angle of the third output transmission body 273 with respect to the output shaft 42 is adjusted so that the protrusion 63 and the third transmission hole 273H are in positions corresponding to each other.

  Therefore, when the input shaft 41 is in the second input state and the output shaft 42 is rotated by an angle β from the initial output state, the actuator 235 moves the switching moving portion 44 to the right by the switching drive portion 46. By doing so, as shown in FIG. 17A, the first transmission protrusion 63 can be inserted into the third transmission hole 273H of the third output transmission body 273.

  Thereby, when the input shaft 41 is rotated from the second input state to the first input state by the input shaft rotating portion 43, the actuator 235 transmits the force from the first transmission protrusion 63 of the input transmission arm portion 62 to the third. By transmitting to the 3rd transmission hole 73H of the output transmission body 73, the output shaft 42 is rotated and it will be in the state shown in FIG.17 (B). Hereinafter, the state in which the first transmission protrusion 63 is inserted through the third transmission hole 273H in this way is also referred to as a third transmission state.

  Here, as shown in FIG. 18A corresponding to FIG. 10A and FIG. 11A, in addition to the virtual straight line 35X and the straight line 63X, the output center line 42C of the output shaft 42 and the first An imaginary straight line 273X along the third output transmission body 273 that connects the centers of the transmission protrusions 63 is defined. Furthermore, the ratio of the length of the straight line 63X and the straight line 273X is Q: R.

  In this third transmission state, the actuator 235 corresponds to FIG. 18A by rotating the input shaft 41 from the second input state to the first input state by the input shaft rotating unit 43 (FIG. 7). The state shown in FIG. Here, when the rotation angle of the input shaft 41 is an angle θ and the rotation angle of the output shaft 42 is an angle γ, this angle γ can be expressed as follows by using the ratio Q: R and the angle θ described above ( 3) It can be expressed as:

  γ = (Q / R) θ (3)

  That is, the actuator 235 has a reduction ratio when transmitting rotation from the input shaft 41 to the output shaft 42 via the switching transmission unit 247 (the switching movement unit 44, the output transmission unit 245, and the switching driving unit 46). L), (M / N) or (Q / R).

  Further, in the state shown in FIGS. 17B and 18B, the output shaft 42 rotates by an angle β from the initial output state (FIG. 11A) and further rotates by an angle γ in the opposite direction. doing. That is, the rotation angle of the output shaft 42 from the reference line 35B at this time is an angle (β−γ).

  Furthermore, when the rotation angle of the output shaft 42 in the actuator 235 is arranged according to the angle of the input shaft 41 (first input state or second input state) and the position (right side or left side) of the switching moving unit 44, FIG. And corresponding state transition diagram of FIG.

  Thus, in addition to switching to the first transmission state (FIG. 8) or the second transmission state (FIG. 16) in the first input state, the actuator 235 has the second transmission state or the third transmission state in the second input state. By switching to (FIG. 17), the rotation angle of the output shaft 42 can be switched to the angle α, the angle β, or the angle γ.

  In the above configuration, the actuator 235 in the banknote depositing / dispensing machine 210 of the automatic teller machine 201 according to the third embodiment rotates the input shaft 41 and moves the switching moving unit 44 in the left-right direction, thereby moving each other. The first transmission state (FIG. 8), the second transmission state (FIG. 16), or the third transmission state (FIG. 17) are switched. As a result, the actuator 235 sets the rotation angle of the output shaft 42 to the angle α, although the rotation angle of the input shaft 41 by the input shaft rotation unit 43 (FIG. 7) is only one angle θ. It is possible to switch between three ways, β and angle γ.

  At this time, the actuator 235 maintains the time required for the rotation almost constant as in the first embodiment, regardless of whether the rotation angle of the output shaft 42 is switched to the angle α, the angle β, or the angle γ. it can.

  In particular, the actuator 235 moves the first transmission protrusion 63 inserted through the first transmission hole 71H of the first output transmission body 71 in the first transmission state into the third output transmission body 273 in the third transmission state (FIG. 17). It was made to pass through the third transmission hole 273H. For this reason, the actuator 235 switches the switching movement unit 44 to two positions such as the left side or the right side by the switching drive unit 46 and combines the rotation angle of the input shaft 41 to provide three force transmission paths. Can be switched. That is, the configuration of the actuator 235 can be simplified as compared with the case where the switching driving unit 46 switches the switching moving unit 44 to three positions.

  According to the above configuration, the banknote depositing and dispensing machine 210 of the automatic teller machine 201 according to the third embodiment rotates the input shaft 41 by the input shaft rotating unit 43 and the switching drive unit 46 in the actuator 235. As a result, the switching moving unit 44 is moved in the left-right direction to switch to the first transmission state (FIG. 8), the second transmission state (FIG. 16) or the third transmission state (FIG. 17). At this time, in the actuator 235, since the rotation angle of the input shaft 41 by the input shaft rotation unit 43 is one angle θ, the rotation angle of the output shaft 42 is changed to three angles α, β, and γ. While switching, all the time required for the rotation can be kept equal.
