JP-A-2004-295868 (FIGS. 10 to 17, paragraph numbers 0051 to 0103)

When the number of stored banknotes is increased in the first prior art, it has been found that there is a problem that the mobile body is not held at the banknote receiving position when the state in which banknotes are not received becomes long, and banknotes cannot be stored.
As a result of intensive studies, the present inventors have elucidated the following causes.
The banknote in the holding part is pressed against the moving body and held by pressing means that is elastically biased.
The pressing force by the pressing means must increase along with the increase in the number of stored bills.
The reason for this is that banknotes are bent due to use and the apparent thickness increases due to wrinkles or the like, so that the holding portion, and thus the entire apparatus, is enlarged unless a pressing force is applied to extend them.
The movable body in the prior art is held at the bill receiving position using the electric motor and the resistance of the speed reducer as a rotation driving device and the short brake of the electric motor.
When the number of stored bills increases, the pressing force of the pressing means is inevitably increased, and as a result, the pressing force against the moving body also increases.
The increase in the pressing force exceeds the braking force by the motor, the reduction resistance of the speed reducer and the short brake, and the moving body is moved little by little.

  In order to solve this, it is conceivable to add an electric or mechanical brake or a stopper for preventing the movement of the moving body, but it cannot be easily adopted because it increases the cost and enlarges the apparatus.

A first object of the present invention is to provide a bill moving body driving device in a bill storage device in which a bill moving body is not moved by a pressing force by a pressing means.
The second object of the present invention is to provide a bill moving body drive device in a bill storage device in which the bill moving body is not moved by the pressing force of the pressing means without causing an increase in cost and size.

In order to achieve the above object, the present invention has the following configuration.
That is, the invention described in claim 1 is detachable from the bill accepting device, and is disposed in the bill storage box for stacking and storing bills in the bill holding portion, and in the bill storage box, and is in the receiving position and the storing position. A moving body that moves the banknotes that have been moved and moved to the banknote holding unit, a rotary drive device that is disposed in the banknote receiving device, and a crankpin that is built in the banknote storage box and that rotates in response to the rotational motion of the rotary drive device A connecting rod for operatively connecting the crank pin and the moving body), and the moving body is moved to the receiving position and the storing position of the banknotes by the rotational movement of the crankpin. In the drive device, at a position where the connecting rod slightly passes through a bottom dead center located on a straight line passing through the rotation center of the crank pin. In the banknote storage apparatus , a stopper for locking the crank pin directly or indirectly is provided, and the receiving position is a position where the crank pin is locked by the stopper and the moving body is stopped . It is a banknote moving body drive device.

In a preferred embodiment of the present invention, the crank pin has a stopper for locking the crank pin directly or indirectly near top dead center.

In the first preferred embodiment of the present invention, the moving body that receives the banknote is moved from the rotation driving unit of the banknote receiving apparatus via the driving apparatus.
Specifically, when the moving body moves toward the banknote receiving position by rotation in one direction of the rotation driving unit, and the receiving position is detected by the receiving position detection device, the rotation driving unit is stopped by the control device, It is held in the receiving position.
When the received banknote is moved to the holding unit, the rotation driving unit is rotated in the opposite direction to the above, and the moving body is moved to a storing position in a direction away from the holding unit via the driving device.

When the moving body reaches the storage position, it is detected by the storage position detection device, and the rotation of the rotation drive unit is stopped.
Thereafter, the rotation drive unit rotates in the opposite direction to the above, and the moving body moves toward the receiving position and is held at the receiving position.
Therefore, the moving body moves to the storage position of the banknote and returns to the receiving position by forward and reverse rotation of the rotation driving unit, and thus is not driven against the spring force, and power consumption is reduced.

The crankpin is stopped by a stopper at a position slightly past the bottom dead center.
As a result, even if the crank pin tries to rotate normally by the pressing force of the pressing means, it is locked by the stopper and cannot rotate.
Since the crank pin has passed the bottom dead center, no reverse torque is generated in the crank pin by the pressing force of the pressing means, and as a result, it does not rotate.
As described above, the moving body is held at the receiving position without being moved by the pressing force of the pressing means.

In a preferred embodiment of the invention , the crankpin is locked to a stopper near its top dead center and stopped.
In other words, the crank pin is locked by the stopper at the storage position of the moving body to prevent overrun.
Thereby, the trouble by a banknote contacting a moving body again can be prevented.

  A banknote storage box that is detachable from the banknote receiving device and that stores and stacks banknotes in the holding section, and is arranged in the banknote storage box, and moves to the receiving position and the storing position to move the received banknotes to the holding section. A movable body composed of a pair of channel-type receiving bodies arranged facing each other at an interval of, a rotational driving device arranged in the banknote receiving device and rotatable, incorporated in the banknote storage box, and a rotational motion of the rotary driving device Banknote storage including a crankpin that rotates in response to the rotation, and a connecting rod that operatively connects the crankpin and the moving body, wherein the moving body is moved to a banknote receiving position and a storing position by rotation of the crankpin. In the moving body drive device of the apparatus, the crank pin and the moving body are operatively connected by a connecting rod, and the The cup is stopped by a stopper directly or indirectly at a position slightly passing through a bottom dead center located on a straight line passing through the center of rotation, and the moving body is set to be positioned at a bill receiving position. It is a banknote moving body drive device in the banknote storage apparatus which performs.

As shown in FIG. 1, in the banknote receiving apparatus 100, a banknote identification apparatus 102 is disposed at the upper front portion, and a banknote storage box 106 is inserted into a safe mounting body 104 below the banknote identification apparatus 102 and locked by a lock apparatus 107.
The banknote receiving apparatus 100 is built in a vending machine, a money changer, or the like, and is disposed outside a device in which only the banknote guide 108 of the banknote recognition apparatus 102 is built.

The banknote identification device 102 will be described with reference to FIGS.
The bill recognition device 102 has a function of identifying the authenticity and denomination of the bill BN inserted into the bill insertion slot 112, sending the genuine bill to the bill storage box 106, and returning the false bill to the bill insertion slot 112.
The bill recognition device 102 obtains the characteristics of the bill BN optically or the like, which conveys the bill BN inserted into the horizontally long bill insertion slot 112 along the bill guide 108 toward the outlet 114 or the bill insertion slot 112. A bill feature acquisition device 118 is included.
The conveying device 116 is driven in the pull-in direction or the discharge direction by the first electric motor 120 that is selectively forwardly or reversely rotated.
The banknote BN inserted into the banknote insertion slot 112 is detected by a sensor (not shown), and the transport device 116 is driven in the pull-in direction.
As a result, the banknote BN is transferred through the banknote passage 122 and passes through the banknote feature detection device 118.
The authenticity and denomination are determined based on the banknote characteristics acquired by the banknote characteristic detection device 118. In the case of a genuine banknote, it is pulled in as it is and stored in the banknote storage box 106. In the case of a false banknote, the first electric motor 120 Due to the reverse rotation, the transport device 116 is reversely fed and ejected from the bill insertion slot 112.

Next, the safe mounting body 104 will be described with reference to FIGS.
The safe mounting body 104 has a function of detachably holding the banknote storage box 106 and attaching the banknote identification device 102 to a predetermined position.
The safe mounting body 104 is a rectangular casing having a horizontal mounting hole 124 in the center.
The bill recognition device 102 and the bill guide body 126 are fixed to the upper surface of the safe mounting body 104, and the bill BN is curved by the bill guide body 126 between the outlet 114 of the bill recognition device 102 and the receiving port 164 of the bill storage box 106. Guided while drawing.

Next, the banknote storage box 106 will be described with reference to FIGS.
The banknote storage box 106 has a function of accepting a banknote BN determined to be authentic by the banknote recognition apparatus 102 and holding it in a stacked state.
As shown in FIGS. 1 and 2, the bill storage box 106 is configured by covering a box-shaped sheet metal frame 128 with a box-shaped cover 129 as a whole.

Next, the structure of the frame 128 will be described with reference to FIGS.
4 is a view seen from the right side, the left and right in the description are opposite to the left and right in FIG.
The left side wall 130 and the right side wall 131 are erected from both end portions of the plate-like base 132 (FIGS. 4 and 5 are suspended in the longitudinal direction for convenience, but when used, as shown in FIG. Laid down).
A left top plate 134 and a right top plate 136 extend in parallel with the base 132 from the left side wall 130 and the right side wall 131, and a space 138 is formed between the tips.

Into the space 138 surrounded by the base 132, the left side wall 130, the right side wall 131, the left top plate 134, and the right top plate 136, the drawing device 140 for drawing the bills inside, and the drawn bill BN is moved to the holding unit 142 A pressing device 146 for holding the banknote BN is disposed on the moving body 144 and the holding unit 142 for the purpose.
Further, a right driving device 148R and a left driving device 148L for moving the moving body 144 are arranged in the thin right driving device space 147R and left driving device space 147L between the frame 128 and the cover 129.

Next, the cover 129 will be described with reference to FIGS.
The cover 129 is made of sheet metal and has a box shape as a whole, and the above-described frame 128, the drawing-in device 140, and the driving device 148 are closely inserted into the internal space.

Next, the retractor 140 will be described with reference to FIGS.
The drawing-in device 140 has a function of drawing the banknote BN delivered from the banknote guide 126 into the banknote storage box 106.
In the space 138, one end of a rectangular plate-like supporter 150 is fixed to the left top plate 134 and the right top plate 136.
The other end portion of the supporter 150 extends toward the holding portion 142, and the retracting device 140 is attached to the end portion.

The drawing-in device 140 includes a pulley device 152 and a transport body 154.
The pulley device 152 includes a shaft 156 rotatably supported by the supporter 150 and a toothed pulley 158 fixed to an end portion thereof.
However, the toothed pulley 158 can be changed to a normal grooved pulley or the like.
A plurality of the pulley devices 152 are arranged along the length of the supporter 150, in this embodiment, five units.

The transport body 154 is wound around the pulleys 158 at both ends, and the intermediate pulley 158 restricts the movement of the transport body 154 so that the transport body 154 keeps contact with the banknote BN.
Therefore, when the banknote BN can be reliably conveyed, only the pulley devices 152 at both ends can be provided, and the intermediate pulley device 152 can be omitted.
The pulley device 152 at one end is located at a slit-shaped receiving port 164 located on the side wall 162 of the banknote storage box 106 as shown in FIG. 3, and the shaft 166 to which the pulley 158 is fixed as shown in FIG. Extends to the right drive device space 147R, and a driven gear 168 is fixed to the end thereof.

As shown in FIG. 2, this driven gear 168 is drivingly connected via a transmission mechanism 172 to a driving gear 170 driven by the first driving electric motor 120 of the transport device 116 of the banknote recognition device 102.
In this embodiment, the carrier 154 is a toothed belt, but can be changed to a ring-shaped belt made of a flexible material such as a flat belt or a rope.

In other words, the transport body 154 only needs to have a function of transporting in one direction by frictional contact with the banknote BN.
The contact portion of the transport body 154 with the banknote BN is a transport section 173 (see FIG. 7).
A roller 174 is disposed so as to elastically contact the carrier 154 wound around the pulley device 152 at the end portion on the receiving port 164 side.

Accordingly, the true banknote BN determined by the banknote recognition apparatus 102 is sent to the receiving port 164, sandwiched between the transport body 154 and the roller 174, and sent in the transport direction of the transport unit 173.
The transport unit 173 in contact with the banknote BN is on the loose side when driven.
In other words, the true banknote BN is drawn into the banknote storage box 106 and conveyed in the traveling direction of the conveyance unit 173 by frictional contact with the conveyance unit 173.

The drawing-in device 140 is preferably disposed on both sides of the supporter 150 as in the embodiment.
This is because the frictional force with the banknote BN is increased and the frictional force is applied to the banknote BN in a plane, so that the banknote BN can be translated.
However, the drawing-in device 140 can be disposed only on one side of the supporter 150 by increasing the width of the transport unit 173 or the like.
The drawing-in device 140 has a function of drawing the true banknote BN determined by the banknote identification device 102 into the banknote storage box 106.
Therefore, the drawing-in device 140 can be changed to another device having the same function.

Next, the moving body 144 will be described with reference to FIGS.
The moving body 144 has a function of moving the banknote BN drawn into the banknote storage box 106 by the drawing-in device 140 to the holding unit 142.
The moving body 144 includes a channel-shaped right moving body 178 and a left moving body 180 that are located on the sides of the retracting device 140.
Since the right moving body 178 and the left moving body 180 have the same structure and are arranged in the space 138 symmetrically with respect to the drawing-in device 140, the right moving body 178 will be described as a representative.
The right moving body 178 is formed in a lateral T-shape by a slider portion 182 and a first holding portion 184 that is positioned at an end portion of the slider portion 182 and extends in a direction orthogonal to the slider portion 182.

The first holding part 184 is bent at a right angle with respect to the slider part 182, and is substantially parallel to the base 132, in other words, the drawn banknote BN.
A plate-like second holding portion 186 formed of a resin with a predetermined interval is fixed to the slider portion 182 to the right of the first holding portion 184 (downward in FIG. 7).
A left holding portion 192 having a predetermined width and height (see FIG. 7) surrounded by three sides by the lower surface 183 of the first holding portion 184, the upper surface 185 of the second holding portion 186, and the side surface 187 of the slider portion 182 is configured. ing.
The thickness of the left holding part 192 is preferably as thin as possible within a range in which the banknote BN can move smoothly in order to reduce the size of the banknote storage box 106.

The left holding portion 192 can be integrally formed into an F shape together with the slider portion 182 using resin.
The second holding unit 186 is formed to have a predetermined thickness so as not to contact the banknote BN held in the holding unit 142 when the banknote BN is curved by the drawing device 140.
The receiving port 164 side of the second holding unit 186 has a slope 190 so as to guide the banknote BN to the left holding unit 192 (see FIG. 4).
Similarly, a right holding portion 188 is formed in the right moving body 178.

The slider portion 182 is disposed so as to be movable in the longitudinal direction in the groove 196 of the resin guide portion 194 fixed to the inner surface of the right side wall 131 (in FIG. 6, it can be moved in the left-right direction).
Further, as shown in FIG. 2, guide pins 198A and 198B projecting outward from the left end and right end of the slider portion 182 are slidably inserted into the long holes 200A and 200B formed in the right side wall 131, respectively. (The same applies to the left side wall 130 side).
Therefore, the right moving body 178 and the left moving body 180 can reciprocate integrally and linearly while being guided by the long holes 200A and 200B.

As shown in FIG. 3, when the banknote receiving device 100 is in a standby state, the left holding unit 192 and the right holding unit 188 are set to be positioned on the extension of the receiving port 164.
Therefore, the left holding unit 192 and the right holding unit 188 are positioned on a virtual plane 193 extending after the receiving port 164 in the standby state, in other words, the receiving state of the banknote BN (see FIG. 3), and are conveyed by the drawing device 140. The end of the bill BN to be moved is movable.
As apparent from FIG. 3, since the virtual plane 193 is substantially vertical in this embodiment, when the banknote BN moves in the virtual plane 193, there is an effect that it is pulled down by gravity.

When a sensor (not shown) detects that the rear end portion of the drawn banknote BN has passed the roller 174, the first electric motor 120 is stopped, and conveyance of the banknote BN by the drawing device 140 is stopped.
As a result, the banknote BN is temporarily held with its left and right ends positioned at the left holding part 192 and the right holding part 188, respectively.
Therefore, the virtual plane 193 is also a temporary storage unit 195 for the banknote BN.
Further, the right moving body 178 and the left moving body 180 are movable in the direction orthogonal to the virtual plane 193.

  That is, the moving body 144 moves along the supporter 150 so that the end of the banknote BN is positioned closer to the banknote presser 204 than the left back surface 206 and the right back surface 208 of the second holding unit 186. It is possible to move to the storage position RP that has moved to the side (above the position shown in FIG. 12).

Next, the pressing device 146 will be described with reference to FIG.
The pressing device 146 includes a banknote presser 204 that comes into contact with the banknote BN, and a biasing body 210 that biases the banknote presser 204 toward the left back surface 206 and the right back surface 208 of the second holding unit 186.
The bill presser 204 has a plate shape and is movably disposed between the left and right slider portions 182.

The biasing body 210 is a spring 212 having one end fixed to the base 132 and the other end fixed to the bill presser 204.
The urging force of the urging body 210 decreases the stacking thickness of the banknotes BN in order to increase the amount of banknotes BN retained, and holds the banknotes BN retained in the retaining section 142 so as not to buckle. When both ends of the banknote BN sandwiched between the banknotes BN are moved by the moving body 144, the banknote BN is set to be held between the drawing-in device 140 and the banknote BN held.

Therefore, the urging body 210 can be changed to another device having the same function.
In this embodiment, the urging body 210 has two cones with a cone-shaped spring 212 in parallel and a flat plate-shaped stabilizer 211 interposed therebetween.
This is because, when the number of stored sheets is increased, the stroke of the bill presser 204 is increased, so that using two parallel cone-shaped springs causes buckling, and the bill BN cannot be held.
In addition, when two springs of the same size are arranged in parallel, there is an advantage that the parts can be manufactured at low cost by sharing the parts.

The holding unit 142 is a space sandwiched between the left back surface 206, the right back surface 208, the transport unit 173, and the bill presser 204.
Therefore, when the banknote BN is not held, the banknote presser 204 contacts the left back surface 206 and the right back surface 208.

Next, the structure of the driving device 148 will be described with reference to FIGS.
The driving device 148 includes a left driving device 148L and a right driving device 148R attached to the left side wall 130 and the right side wall 131, respectively.
Since the left driving device 148L and the right driving device 148R have the same structure, the right driving device 148R will be described as a representative.
The same reference numerals are assigned to the same parts of the left driving device 148L.

A crank gear 230 is rotatably attached to a fixed shaft 228 protruding from the right side wall 131 to the right drive unit space 147R.
One end of a connecting rod 234 as a link 233 is rotatably attached to a crank pin 232 protruding from the side surface of the crank gear 230, and the other end of the connecting rod 234 is rotatably attached to a pin 235 protruding from the slider portion 182.
As a result, the right holding part 192 and the left holding part 188 are connected to the receiving port 164 near the bottom dead center of the crank pin 232 (a state where the crank pin 232 is positioned on the line L1 in FIG. 6) due to the rotation of the crank gear 230. It is located in the banknote receiving position SP opposite to.

In this case, the crank pin 232 at a position slightly overspeed than a line L1 connecting the rotation center of the pin 235 and the crank gear 230, the protrusion 23 1 projecting from the crank gear 230 is engaged by the first stopper 236 Yes.
In other words, the crank pin 232 is stopped after slightly overrunning the bottom dead center which is a dead point.

The first stopper 236 includes a buffer 240 made of an elastic resin fixed to an L-shaped bracket 238 fixed to the right side wall 131.
With this configuration, when the crank pin 232 receives a leftward force in FIG. 6 via the connecting rod 234, counterclockwise torque acts on the crank gear 230, but the protrusion 231 prevents rotation by the first stopper 236. Is done.
In other words, since only the counterclockwise torque is generated as described above, even if the moving body 144 receives the moving force from the banknote holder 204 to the left in FIG. 6 via the banknote BN, no clockwise torque is generated. Keep it still.

Furthermore, in the present embodiment, a holding device 237 for the crank gear 230, in other words, the crank pin 232 is provided.
Holding device 237 has a function of holding the crank pin 232 to a dead point near, specifically has a function to continue the state where the projection 23 1 is in contact with the first stopper 236.
The holding device 237 is a leaf spring 239 having one end fixed to the bracket 238.
Formed in a crank shape by a pressing portion 241 inclined to the first stopper 236 side at the tip of the leaf spring 239 and subsequently a driven portion 243 inclined in the direction away from the first stopper 236, in other words, in the direction opposite to the pressing portion 241. Has been.
When the crank gear 230 is rotated counterclockwise from the position of FIG. 10, the projection 23 1 After passing over the driven part 243 is bent leaf spring 239 by pushing the driven part 243, the pressing by the spring force of the leaf spring 239 The first stopper 236 is locked while receiving a biasing force from the portion 241 toward the first stopper 236.
Thus, if the crank gear 230 does not receive the rotational force from the gear 248, the projection 23 1 is pressed so as to continue the contact with the first stopper 23 6 by the leaf spring 239.

In addition, when an encoder (not shown) is connected to the crank gear 230 and the crank pin 232 is accurately stopped at the bottom dead center (the crank pin 232 is located on the line L1), the crank gear 230 is similarly rotated. Torque can not be generated.
However, in the phase where the bottom dead center is slightly over-rotated as in the embodiment, the crank pin 232 can be prevented from rotating with a simple configuration by being locked by the first stopper 236, and the apparatus can be configured at low cost. There are advantages.

Further, when the crank pin 232 stops near the bottom dead center, the torque to the crank pin 232 generated by the bill presser 204 is extremely small. Therefore, the rotation resistance of the second electric motor 254 and the speed reducer or the second electric motor 254 is short-circuited. Can not exceed the static force combined with the brake.
In other words, when the crank pin 232 is located near the bottom dead center, the position of the moving body 144 is not changed by the external force.

When the crank pin 23 2 is located at the top dead center serving dead point (state shown in FIG. 11), positioned in the bill storage position RP most distant from carrier 154.
At this time, the connecting rod 234 is locked by the second stopper 242 fixed to the right side wall 131.
The second stopper 242 includes a buffer body 246 made of an elastic resin fixed to an L-shaped bracket 244 fixed to the right side wall 131.
As a result, the crank pin 232 is prevented from rotating beyond the top dead center by the second stopper 242.

The crank gear 230 meshes with the gear 248 disposed in the right drive device space 147R.
The gear 248 is fixed to the end portion of the rotating shaft 250 that is rotatably attached to the frame 128, and the gear 252 fixed to the other end portion is engaged with the crank gear 230 of the left driving device 148L.
Safe attachment body 104 rotary drive device 25 1 which is fixed to the upper surface, for example a toothed belt wound between the second electric motor 254 gear 2 58 fixed to the output shaft 256 of the speed reducer (see FIG. 2) The rotating shaft 264 rotatably held by the safe mounting body 104 is rotated via 260 and the timing pulley 262.

Gears 266 and 268 are fixed to both ends of the rotating shaft 264 and are drivingly connected to the gears 248 and 252 respectively.
In other words, when the bill storage box 106 is mounted in the mounting hole 124, the gear 248 and the gear 266 and the gear 252 and the gear 268 are set to mesh with each other.
Accordingly, when the gear 266 is rotated clockwise, the crank gear 230 is rotated clockwise in FIG. 2 to move the movable body 144 in the bill storage direction (left direction in FIGS. 2 and 6) and to the storage position RP. Move.
When the gear 266 rotates counterclockwise, the crank gear 230 is rotated counterclockwise in FIG. 2, and the moving body 144 is moved to the receiving position SP.

  The driving device 148 has a function of reciprocating the moving body 144 in the direction orthogonal to the virtual plane 193, in other words, the plane of the banknote BN.

A handle 270 for transporting the bill storage box 106 is attached to the outer surface of the top plate 269 adjacent to the top plates 134 and 136 of the cover 129.
Further, as shown in FIG. 2, one end of the side wall 272 opposite to the side wall 162 of the banknote storage box 106 is attached so as to be pivotable with respect to the shaft 274 fixed to the frame 128, and the banknote held in the holding section 142 In order to take out the BN, the lock 276 can be opened and closed by unlocking it.

Next, the receiving position detection device 280 of the moving body 144 will be described with reference to FIG.
The receiving position detection device 280 includes a receiving position light projecting / receiving unit (not shown) and a receiving position detection piece 284.
The receiving position light projecting / receiving unit is mounted in the safe mounting body 104, and the receiving position detecting piece 284 is disposed in the left driving device space 147L.
The reception position light projecting / receiving unit outputs a detection signal when the projection light is blocked by the reception position detection piece 284, and outputs a non-detection signal when the projection light is received.

A portal-shaped receiving light guide 286 is fixed to the back surface of the side wall 162 of the banknote storage box 106 with a bracket (not shown) relative to the receiving position light projecting / receiving unit.
The light receiving surface 288 and the light projecting surface 290 of the receiving light guide 286 are slightly recessed with respect to the surface of the side wall 162.

The receiving position detection piece 284 is one end portion of a lever 314 that is attached to a shaft 292 fixed to the left side wall 130 so as to be pivotable.
The receiving position detection piece 284 is retracted from the detection area (not shown) of the receiving light guide 286 by the spring 298 hooked between the other end of the lever 294 and the locking piece 296 protruding from the left side wall 130. It is energized.

The other end of the lever 294 is located on the movement path of the guide pin 198C. When the moving body 144 is located at the receiving position SP, the lever 294 is moved by the guide pin 198C, and the receiving position detection piece 284 is detected by the receiving light guide 286. Located in the area to block light.
Thereby, since the receiving position light projecting / receiving unit does not receive the projection light, it is determined that the moving body 144 is at the receiving position SP.

When the moving body 144 moves toward the storage position RP, the lever 284 is pivoted counterclockwise in FIG. 5 by the spring 298 and protrudes from the right side wall 131 at a predetermined position where the lever 284 has left the detection area of the receiving light guide 286. Stopped by the stopper 299.
Detecting that the moving body 144 has moved to the receiving position SP, stops the rotation of the second electric motor 254, and hence the drive gear 266, and holds the moving body 144 at the receiving position SP.

Next, the storage position detection device 300 will be described with reference to FIGS.
The storage position detection device 300 includes a storage light projecting / receiving unit (not shown), a storage light guide 302, and a storage detection piece 304.
The storage light projecting / receiving unit has a light projecting unit and a light receiving unit, similarly to the receiving light projecting / receiving unit.
A storage light guide 302 is fixed to the back surface of the frame 128 by a bracket (not shown) relative to the storage light projecting / receiving unit.

The storage light guide 302 is formed in a gate shape, has a storage detection area 306, and is bent into an angle shape.
The storage light receiving surface 308 and the storage light projecting surface 310 are substantially flush with the side wall 162.
The storage detection piece 304 is one end of a lever 314 attached to a shaft 312 protruding from the left side wall 130 to the right drive device space 147R so as to be pivotable.

The lever 314 is urged so that the storage detection piece 304 is retracted from the detection area 306 of the storage light guide 302 by a spring 318 hooked between the locking piece 316 protruding from the left side wall 131.
When the moving body 144 is in the storage position RP, the other end of the lever 314 is rotated clockwise in FIG. 2 by the guide pin 198A, and the storage detection piece 304 is positioned in the detection area 306 to block the light.

Therefore, when no light is received on the storage light receiving surface 308 of the storage light guide 302, it is determined that the moving body 144 is in the storage position RP.
When it is determined that the moving body 144 is at the storage position RP, the second electric motor 254, and thus the drive gear 266, is stopped counterclockwise and then rotated counterclockwise.
Accordingly, the moving body 144 moves from the storage position RP toward the receiving position SP.
When the moving body 144 is in the receiving position SP, the lever 314 is locked by the stopper 314 protruding from the left side wall 130, and the storage detection piece 304 is held at a position away from the detection area 306.

  The light guide 320 for detecting the bill storage box, the light projecting surface 322 and the light receiving surface 324 of the bill position detecting device, and the light projecting surface 326 and the light receiving surface 328 of the full detecting device for detecting the full position of the bill presser 204 are also the side walls 162. It is arranged so as to be slightly recessed.

Next, the control device 330 will be described with reference to FIG.
The control device 330 controls the second electric motor 254 to perform normal rotation or reverse rotation and the first electric motor 120 to perform normal rotation or reverse rotation based on the storage signal P, the detection signals from the receiving position detection device 280 and the storage position detection device 300. .
Specifically, the control device 330 is constituted by a microprocessor or the like.
The control device 330 is controlled based on the flowchart shown in FIG.

Next, the operation of the present embodiment will be described with reference to the flowchart of FIG. 9 and FIGS.
In the standby state, the moving body 144 is held at the reception position SP, the reception position detection piece 284 is located in the detection area of the reception light guide 286, and the storage detection piece 304 is out of the detection area 306.
After the bill storage box 106 is stored in a predetermined position of the mounting hole 124 and locked by the lock device 107, a power switch (not shown) of the bill receiving device 100 is turned on.

The built-in control device 330 rotates the second electric motor 254 in the reverse direction (counterclockwise in FIG. 2) in step S1, and proceeds to step S2.
When the receiving position detection device 280 outputs a detection signal, the process proceeds to step S3, the second electric motor 254 is stopped, and then the process proceeds to step S4 to enter a standby state.
In other words, the gear 266 is rotated counterclockwise in FIG. 2, and the crank gear 230 is rotated counterclockwise via the gear 248.
Further in other words, the projection 23 1 is engaged with the first stopper 236, the crank pin 232 is positioned near the bottom dead center.
Further, since the protrusions 23 1 by the pressing portion 241 of the leaf spring 239 is pressed against the first stopper 236, the projection 23 1 is also power is turned off in the second electric motor 254 in contact with the first stopper 236 continue.
As a result, the slider portion 182 and thus the moving body 144 is moved to the right in FIG. 3 via the pin 235 and moved to the receiving position SP.

When the moving body 144 is positioned at the receiving position SP, the lever 294 is pivoted clockwise by the guide pin 198C, and the standby state shown in FIGS.
As a result, the reception position detection piece 284 advances into the detection area of the reception light guide 286 and blocks the projection light, so that the reception position detection device 280 outputs a detection signal.
In the standby state, the left holding unit 192 and the right holding unit 188 of the right moving body 178 and the left moving body 180 are located directly below the receiving port 164 as shown in FIG.

When a banknote BN is inserted into the banknote insertion slot 112 along the banknote guide 108, the banknote BN is detected by a sensor (not shown), and the first electric motor 120 is rotated.
The rotation of the first electric motor 120 activates the transport device 116 of the bill identification device 102 and rotates the driven gear 168 via the transmission mechanism 172 and the drive gear 170.
As a result, the shaft 166 is rotated, and the drawing-in device 140 starts an operation of drawing the banknote BN into the temporary storage unit 195.
The banknote BN determined to be authentic by the banknote recognition apparatus 102 is sent to the receiving port 164, and the leading end is sandwiched between the transport body 154 and the roller 174.

  As a result, the banknote BN is fed to the temporary storage unit 195 by the transport body 154 and the roller 174 and is drawn into the temporary storage unit 195 by frictional contact with the transporting unit 173, so that the banknote BN travels without jamming. .

  The proceeding banknote BN has its left end positioned at the left holding part 192 and moves while being guided by the lower surface 183 of the first holding part 184, the upper surface 185 of the second holding part 186, and the side surface 187 of the slider part 182.

At this time, since the left end portion of the banknote BN is surrounded on three sides, it does not enter the gap between the other parts.
On the other hand, the right end portion of the banknote BN advances through the right holding portion 188 of the right moving body 178.
When the width varies depending on the denomination, the right end portion of the narrow banknote is guided by the lower surface 183 of the first holding unit 184 and the upper surface 185 of the second holding unit 186 of the right holding unit 188.

In this case, since the bill lengths located on the left and right of the drawing-in device 140 are different and the contact areas of the first holding unit 184 and the second holding unit 186 are different, the bill BN receives rotational force on the surface.
However, since the left end portion of the banknote BN is guided by the side surface 187 of the slider 182, the banknote BN does not move obliquely with respect to the traveling direction.
Immediately after the rear end of the banknote BN passes through the roller 174, it is detected by a banknote position detection device (not shown), and the rotation of the first electric motor 120 is stopped.
As a result, the accepted banknote BN is temporarily held in the temporary holding unit 195.

If the storage signal of the banknote BN is determined in step S4, the process proceeds to step S5.
In step S5, the second electric motor 254 is rotated forward and the process proceeds to step S6.
Since the gear 266 is rotated clockwise by the positive rotation of the second electric motor 254, the crank gear 230 is rotated clockwise in FIG.
As a result, the slider portion 182 is moved to the left in FIG. 6 via the pin 235 (see FIG. 10).
In other words, the crankpin 232 moves from the vicinity of the bottom dead center shown in FIG. 6 toward the top dead center.

The slider 182, the guide pins 198A, 198B are long holes 200A, 200B, the pin 235 is guided along the long hole 43 3, it moves in a direction perpendicular to the escrow unit 195.
In other words, the right moving body 178 and the left moving body 180 move together and pass along the side of the retractor 140, and then move along the supporter 150.
In this process, the central portion of the banknote BN is sandwiched between the drawing device 140 and the banknote holder 204 and held with a predetermined force (see FIG. 12).

Further, after the holding, the right moving body 178 and the left moving body 180 move toward the left top plate 134 and the right top plate 136, so that the left and right ends of the banknote BN are relative to the right moving body 178 and the left moving body 180. Moving.
In this process, the right end of the banknote BN having a short length is disengaged from the right holding portion 188 of the right moving body 178.

Since the right moving body 178 and the left moving body 180 move to the storage position RP near the left top plate 134 and the right top plate 136 at the top dead center of the crank pin 232, the left end portion of the banknote BN is also left of the left moving body 178. It comes off the holding part 192.
In the case of the widest banknote BN, the left and right ends thereof are detached from the right moving body 178 or the left moving body 180 almost simultaneously.
By deviating from the right moving body 178 and the left moving body 180, the banknote BN moves to the holding unit 142.

When the movable body 144 reaches the storage position RP, the lever 314 is pivoted clockwise as shown in FIG. 11 by the guide pin 198A, and the storage detection piece 304 moves to the storage detection area 306 of the storage light guide 302. To block the projected light.
Thereby, the storage position detection apparatus 300 outputs a detection signal.
After determining the detection signal in step S6, the process proceeds to step S7.

In step S7, the second electric motor 254 is stopped, and the process proceeds to step S8.
At this time, if the crank gear 230 is excessively rotated for some reason, the connecting rod 234 is stopped by the second stopper 242 so that it does not excessively rotate near the top dead center.

In step S8, the second electric motor 254 is reversed and the process proceeds to step S9.
The reverse rotation of the second electric motor 254 causes the gear 266 to rotate counterclockwise in FIG.
Thereby, the crank gear 230 is rotated counterclockwise in FIG. 2, and is rotated to the receiving position SP which is the bottom dead center of the crank pin 232 shown in FIG.
By the rotation of the crank gear 230, the moving body 144 is moved from the storage position RP to the receiving position SP shown in FIG.
Accordingly, the banknote BN moved to the holding unit 142 is held between the left back surface 206 and the right back surface 208 and the banknote presser 204 and is held.
Since the guide pin 198C pushes the lever 294 and rotates it clockwise in FIG. 5, the reception position detection piece 284 advances to the detection area of the reception light guide 286 and blocks the projection light.
By this interruption, the receiving position detection device 280 outputs a detection signal.

In step S9, the receiving position detection device 280 determines the detection signal, and then proceeds to step S10.
In step S10, the second electric motor 254 is stopped, so that the moving body 144 holds the receiving position SP.
In the receiving position SP, the projection 23 1 is locked by the first stopper 236 as described above, and, since the position near the bottom dead center of the crank pin 232, does not crank pin 232 is rotated by an external force.
Thereby, the moving body 144 holds the receiving position SP.

In addition, in order to help understanding in this specification, although it demonstrated using upper and lower, right and left in drawing, this invention is not limited by these words,
The receiving position detection device and the storage position detection device can be substituted by detecting the position of another moving body such as a crank gear.
Further, in the present embodiment, the first stopper 236 and the second stopper 242 are not essential constituent requirements.
