When the designated amount of bills B is sent out on the stage 43, the motor M is activated. When the motor M is started, the stage slide mechanism 430 and the shutter opening / closing mechanism 440 connected to the motor M through the driving force transmission mechanism 450 are started. Here, the rotation directions of the gear 452 of the driving force transmission mechanism 450, the gear 431 of the stage slide mechanism 430, and the gear 441 of the shutter opening / closing mechanism 440 are the directions indicated by the arrows in the drawing.

  When the stage slide mechanism 430 and the shutter opening / closing mechanism 440 are started, the gear 431 of the stage slide mechanism 430 and the gear 441 of the shutter opening / closing mechanism 440 start to rotate simultaneously. In this case, the protrusion 432 of the gear 431 of the stage slide mechanism 430 is located at the connecting point between the other guide groove 43C2 and the temporary holding guide groove 43C3 in the guide groove 43C provided on the back surface of the stage 43, and is temporarily held in the guide groove 43C3. Rotate along. Therefore, the stage 43 is stopped during the period in which the protrusion 432 rotates along the temporary holding guide groove 43C3. On the other hand, when the gear 441 of the shutter opening / closing mechanism 440 starts rotating, the cam 442 starts rotating, and the engagement state of the shutter 44 with the cam protrusion 44C gradually becomes shallower (the cam 442 escapes from the cam protrusion 44C). ). When the rear end of the cam 442 passes through the cam projection 44C and the cam 442 is detached from the cam projection 44C, the shutter 44 rotates downward, retreats from the banknote outlet 42 and opens the banknote outlet 42 (FIG. 7 (b)).

  As shown in FIG. 7B, at the stage (process) in which the shutter 44 is retracted from the banknote outlet 42, it was rotated along the temporary holding guide groove 43C3 in the guide groove 43C provided on the back surface of the stage 43. The projection 432 of the stage slide mechanism 430 reaches the one guide groove 43C1 via a coupling point between the temporary holding guide groove 43C3 and the one guide groove 43C1. When the protrusion 432 reaches one guide groove 43C1, the protrusion 432 contacts the groove edge of the one guide groove 43C1 and slides along the groove edge. Thereby, the stage 43 starts sliding movement toward the front (the banknote outlet 42), and the banknotes B accumulated on the stage 43 are gradually exposed from the banknote outlet 42. As described above, the temporary holding guide groove 43C3 in the guide groove 43C is also provided when the shutter opening / closing mechanism 440 is connected to the motor M via the stage slide mechanism 430 and the shutter opening / closing mechanism 440 and the stage slide mechanism 430 are simultaneously started. A function is provided for sliding the stage 43 after the slide movement of the stage 43 is temporarily stopped and the shutter 44 is retracted from the bill payout exit 42. The effect of this function will be described later. Then, when the gear 431 of the stage slide mechanism 430 is half-rotated, the driving of the motor M is temporarily stopped, and the process enters a step of waiting for the banknote B to be taken out with a part of the banknote B exposed from the banknote outlet 42 ( (See (c) of FIG. 7). In this step, the projection 432 in the stage slide mechanism 430 is located at the coupling point between the temporary holding guide groove 43C3 and the other guide groove 43C2 from the one guide groove 43C1 via the temporary holding guide groove 43C3, while the shutter opening / closing mechanism 440. Since the cam 442 is separated from the cam projection 44C of the shutter 44, the shutter 44 is maintained in a state of being retracted from the bill payout outlet 42. In this state, by setting the front edge of the stage 43 to be located behind the rotation trajectory of the shutter 44, the shutter 44 and the stage 43 are prevented from colliding and being damaged due to an unexpected situation. can do.

  A sensor (not shown) that detects the presence or absence of the bill B is disposed at the bill payout outlet 42. When the removal of the bill B is detected based on the signal of this sensor, the motor is detected when the removal of the bill B is detected. M is restarted. When the motor M is restarted, the projection 432 of the gear 431 of the stage slide mechanism 430 comes into contact with the groove edge of the other guide groove 43C3 and slides along the groove edge (see FIG. 7D). Slid rearwardly and return to the original position, while the cam 442 of the shutter opening / closing mechanism 440 approaches the cam protrusion 44C of the shutter 44 and the cam 442 reaches the position of the cam protrusion 44C when the cam 442 reaches the position of the cam protrusion 44C. The tapered tip end of 442 sinks below the cam projection 44C, whereby the cam projection 44C rides on the slope of the cam 442 and advances the shutter 44 to the bill payout outlet 42. When the tapered tip end of the cam 442 of the shutter opening / closing mechanism 440 enters below the cam projection 44C, the thickness of the portion of the cam projection 44C that contacts the tip of the cam 442 gradually increases from the back surface of the shutter main body 44A toward the rear. Since it is formed in a circular arc shape, the point of contact between the two is substantially point contact, and the tip of the cam 442 can smoothly enter under the cam projection 44C. Then, when the cam projection 44C of the shutter 44 rides on the flat surface from the slope of the cam 442, the shutter 44 completely closes the banknote outlet 42, and then the gear 431 of the stage slide mechanism 430 and the gear 441 of the shutter opening / closing mechanism 440 When the motor M is stopped at the stage of half rotation (generally one rotation), the stage 43 and the shutter 44 return to the standby state shown in FIG.

  As described above, in the temporary holding guide groove 43C3 in the guide groove 43C provided on the back surface of the stage 43, the shutter opening / closing mechanism 440 is connected to the motor M via the stage slide mechanism 430, and the shutter opening / closing mechanism 440 and the stage are connected. Even when the slide mechanism 430 is started at the same time, the slide movement of the stage 43 is temporarily held and the stage 43 is slid and moved after the shutter 44 is retracted from the bill payout opening 42. That is, even when the shutter opening / closing mechanism 440 and the stage slide mechanism 430 are simultaneously started, the stage 43 temporarily holds the slide movement, and the slide movement distance after the shutter 44 is retracted from the bill payout opening 42, so that the slide movement distance of the stage 43. Can be shortened. When the shutter opening / closing mechanism 440 and the stage slide mechanism 430 are simultaneously started, the stage 43 is slid after the shutter 44 is retracted from the banknote payout opening 42 itself by increasing the slide movement distance of the stage 43. It is something that can be done. However, when the slide movement distance of the stage 43 is increased, the bill processing apparatus is inevitably increased in size. In this respect, the temporary holding guide groove 43C3 in the guide groove 43C of the present invention is a stage during the period until the shutter 44 is retracted from the bill payout opening 42 even when the shutter opening / closing mechanism 440 and the stage slide mechanism 430 are simultaneously started. Since the stage 43 is slid and moved after the shutter 44 is retracted from the banknote outlet 42, the slide movement distance of the stage 43 can be shortened, contributing to the downsizing of the banknote processing apparatus. To do. Further, since the slide movement distance of the stage 43 can be shortened, the distance between the stage 43 and the shutter 44 can be shortened, and the shutter 44 is used as a stopper for aligning the tips of the bills B fed to the stage 43. It can also be used, and the bill B can be stably exposed to the bill B outlet.

  Further, in the standby state of the banknote handling apparatus, the cam protrusion 44C of the shutter 44 engages with the cam 442 of the shutter opening / closing mechanism 440 and rides on the cam 442, so that an external force that pushes down the shutter 44 is applied. However, the shutter 44 does not rotate downward, and it is possible to reliably prevent an unauthorized attempt to open the banknote payout opening 42.

  Further, when the shutter 44 is moved upward from the state in which the banknote outlet 42 is opened to the banknote outlet 42 and rotates upward so as to close the banknote outlet 42 (state (d) in FIG. 7), When an external force that prevents the shutter 44 from rotating upward is applied, the motor M is idled by the idling means. That is, in the shutter 44 retracted from the banknote payout opening 42, the tip of the cam 442 of the shutter opening / closing mechanism 440 sinks below the cam projection 44C provided on the shutter 44, and the cam projection 44C of the shutter 44 is formed in a tapered shape of the cam 442. When it rides on the slope, it starts to rotate upward so as to advance to the banknote outlet 42. In this manner, when the cam projection 44C of the shutter 44 rides on the tapered slope of the cam 442 and the shutter 44 rotates upward, an external force that prevents the shutter 44 from rotating upward is applied. The rotation of the cam 442 is prevented. The cam 442 is provided integrally with the gear 441 of the shutter opening / closing mechanism 440. Since the shutter opening / closing mechanism 440 is connected to the motor M via the stage slide mechanism 430 and the driving force transmission mechanism 450, the driving force transmission mechanism 450 is provided. A load of a predetermined value or more is applied. In this case, the driving force transmission mechanism 450 that transmits the driving force of the motor M to the stage slide mechanism 430 includes a worm gear 451 that is fixed to the output shaft of the motor M, and a gear 452 that is a spur gear that meshes with the worm gear 451. A motor-side pulley 453 (see FIG. 5B) that is positioned on the lower surface side of the gear 452 and is fixed to the shaft of the gear 452, and a stage that is fixed to the shaft of the gear 431 in the stage slide mechanism 430. A cross-section in which a slide mechanism side pulley 454 and a round belt 455 wound around the motor side pulley 453 and the stage slide mechanism side pulley 454 are in contact with a part of the periphery of the round belt 455. Since it is formed in a V shape (see FIG. 6), it is less than a predetermined value between the round belt 455 and the motor pulley 453. The motor M slippage is generated between both when the took the load to idling. Therefore, the shutter 44 is prevented from entering the banknote payout opening 42, such as when a finger is caught in the process of closing the banknote payout opening 42, or when an obstacle is pinched in the shutter 44. Even when a large external force is applied and a load of a predetermined value or more is applied between the round belt 455 and the motor-side pulley 453, the motor M can rotate and is not damaged. During the period when the motor M is idling, the gear 431 of the stage slide mechanism 430 and the gear 441 of the shutter opening / closing mechanism 440 are held at the stop positions, so that the external force applied to the shutter 44 is removed. Resumes rotation at the same time. Therefore, the synchronized state of the stage slide mechanism 430 and the shutter opening / closing mechanism 440 can be maintained even if the motor M idles.

  Here, when an external force that prevents the shutter 44 from entering the banknote payout exit 42 is applied and a load of a predetermined value or more is applied between the round belt 455 and the motor-side pulley 453 (that is, the motor M is When idling), after stopping the motor M once, it is preferable to reverse the motor M for a certain period of time and to return to the normal forward operation. By reversing the motor M in this manner for a certain period of time, when a finger is caught in the shutter 44, the finger can be pulled out without difficulty and the finger can be protected, and an obstacle is caught in the shutter 44. If it is, the obstacle can be dropped to return to normal operation. In the reverse rotation operation of the motor M, when the motor M runs idle, an overcurrent is generated in the motor. For example, an overcurrent detection means is inserted in the power supply circuit to the motor M, and the detection from the overcurrent detection means is performed. Can be done based on output.

As described above, according to the banknote handling apparatus according to the embodiment of the present invention, the banknote handling apparatus that pays out the banknote B fed out from the banknote storage to the banknote payout outlet 42, and the fed out banknotes B are stacked. A stage 43 placed in front of the stage 43 and a shutter 44 that opens and closes the banknote payout opening. The shutter 44 opens the banknote payout opening and then slides the stage 43 toward the banknote payout opening. In the banknote processing apparatus that moves and pays out the banknote B, a stage slide mechanism 430 that slides the stage 43, a shutter opening / closing mechanism 440 that opens and closes the shutter 44, and a drive that transmits the driving force of the motor M to the stage slide mechanism 430. A force transmission mechanism 450, and the stage slide mechanism 430 is moved forward through the driving force transmission mechanism 450. The shutter opening / closing mechanism 440 is connected to the motor M through the stage slide mechanism 430, and rotates the motor M when a load greater than a predetermined value is applied to the driving force transmission mechanism 450. The stage slide mechanism 430 is provided with a projection 432 provided on the gear 431 provided on the back surface of the stage 43 and a back surface of the stage 43, and the projection 432 is loosely fitted and the stage 43 The guide groove 43C extends in a direction orthogonal to the sliding direction, and the guide groove 43C is configured such that one guide groove 43C1 on the rotation direction side of the protrusion 432 is located on the front side of the other guide groove 43C2. A guide groove between the one guide groove 43C1 and the other guide groove 43C2 having a step in the sliding direction of the stage 43. 3 is coupled with the escrow guide 43C3 along the rotation locus of the projection 432, by the projection 432 is located at the point of attachment of the other guide groove 43C2 and escrow guide groove 43C3 in the standby state of the stage 43, the stage 43 and the shutter 44 can be driven by a common motor M, so that the cost can be reduced as compared with the case where dedicated driving sources are provided for the stage 43 and the shutter 44, respectively. Further, when the shutter 44 is stopped when the bill 44 is closed by the shutter 44 and the load is applied to the driving force transmission mechanism 450 by a predetermined value or more, the motor M is idled by the idling means. The motor M can be prevented from being overloaded, and the shutter 43 and the stage 44 are maintained at the stop position when the motor M idles, and the shutter 44 is stopped when the pinched fingers are pulled out. When released, the stage slide mechanism 430 and the shutter opening / closing mechanism 440 resume operation simultaneously, so that the operations of the shutter 44 and the stage 43 can be resumed synchronously from the stop position.

  In the above-described embodiment, the groove of the motor-side pulley 453 constituting the driving force transmission mechanism 450 is formed in a V-shaped cross section that contacts a part of the peripheral edge of the round belt 455, and the motor M is loaded with a load greater than a predetermined value. The motor M is configured to run idle when applied, but the groove of the stage slide mechanism side pulley 454 around which the round belt 455 is wound may be formed in a V-shaped cross section. The groove may be formed in a V-shaped cross section, and is not limited to the embodiment.
