In the above mechanism, whether or not a bill is present between the plate-like members is determined based on a detection signal of a light receiving element attached to the plate-like member. However, in this method, the wiring to the element exists within the range of rotation and movement of the plate-like member, and the wiring member is pulled and disconnected when the plate-like member is rotated and moved. There is a possibility that a failure such as entanglement with the plate-like member may occur.

  In addition, since the rotation angle, movement width, and the like of the plate-like member are restricted by the length of the wiring cord, the amount of bills that can be stacked and pinched is limited, and it is difficult to increase the amount of bills accommodated.

In order to solve the above-described problem, in a medium processing apparatus having a rotary input / output mechanism that takes in the medium by sandwiching and rotating the medium, the light emitting element and the light receiving element that detect the presence of the medium are inserted into the medium processing apparatus. It was made to provide in the said device part out of the range of rotation of a taking-out mechanism.

With the configuration as described above, there is no trouble that the wiring cord is disconnected or the wiring cord is entangled with the plate-like member with the rotation of the plate-like member, and further the rotation angle and movement width of the plate-like member are eliminated. Etc. are not restricted by the length of the wiring cord, so that the amount of bills that can be stacked and pinched can be increased.

  Hereinafter, the arrangement method of a translucent part is demonstrated using the bill press 1 as an example. As shown in FIG. 4, the plane of the bill press 1 is provided with translucent portions T1a to T5a including holes or the like opened so that the light from each of the light emitting elements described above is transmitted. The translucent portion T1 is a point where the optical axes of the light emitting element 10a and the light receiving element 10b intersect with the bill press 1 in a standing state, and is approximately half of the short direction of the bill A, that is, the vertical direction in FIG. It is arranged at the position.

  The translucent portion T2a is approximately half of the short direction of the banknote A, that is, the vertical direction in FIG. 1, at the point where the optical axes of the light emitting element 11a and the light receiving element 11b intersect the standing bill press 1. Arranged in position. The translucent part T3a is a point where the optical axes of the light emitting element 12a and the light receiving element 12b intersect the standing bill press 1, and is arranged on the left side in the longitudinal direction of the bill press 1, and the short side direction is the standing bill A. It is installed in the lower part of the bill press 1 so that the vicinity of the lower end of can be detected. The translucent portion T4a is a point where the optical axes of the light emitting element 13a and the light receiving element 13b intersect the standing bill press 1, and is arranged on the right side in the longitudinal direction of the bill press 1, and the short side is the standing bill A. It is installed in the lower part of the bill press so that the vicinity of the lower end of can be detected. The translucent portion T5a is a point where the optical axes of the light emitting element 14a and the light receiving element 14b intersect the standing bill press 1, and is disposed on the left side in the longitudinal direction of the bill press 1, and the short side direction is a standing bill. It arrange | positions at the lower part of the bill press 1 so that the lower end vicinity of A can be detected.

  The dimension of the arrangement | positioning space | interval of the longitudinal direction of translucent part T1a-T5a is set to the width | variety equivalent to the average width E of the four folded banknote A, or the width | variety below it. Thereby, even if it is a case where the banknote A is inserted in a four-fold state without being opened, it can be detected by any one of the light receiving elements.

  When the rotating part 4 is in the standing state as shown in FIG. 1, the light emitted from the light emitting element 10a passes through the light transmitting parts T1a, T1b and T1c and reaches the light receiving element 10b. Further, light emitted from the light emitting element 11a passes through the light transmitting portions T2a, T2b, and T2c and reaches the light receiving element 11b. Further, light emitted from the light emitting element 12a passes through the light transmitting portions T3a, T3b, and T3c and reaches the light receiving element 12b. In addition, light emitted from the light emitting element 13a passes through the light transmitting portions T4a, T4b, and T4c and reaches the light receiving element 13b. Further, light emitted from the light emitting element 14a passes through the light transmitting portions T5a, T5b, and T5c and reaches the light receiving element 14b. With the structure described above, light can be detected between the light emitting elements 10a to 14a and the light receiving elements 10b to 14b in the rotating unit 4.

  Next, the operation of the present embodiment will be described. At the time of depositing, as shown in FIG. 1, the position of the rotating unit 4 is initialized and the standing position is set with respect to the customer service port 15. Subsequently, when the shutter 16 is opened and the bill A is inserted into the accumulation space, the light emitting elements 10a to 14a emit light under the control of the control unit based on the detection signal of a sensor near the shutter 16 (not shown). The light passes through the light transmitting portions T1a to T5a, T1b to T5b, and T1c to T5c of the bill press 1, the stage 2, and the pool portion 3, and then is detected by the light receiving elements 10b to 14b.

  When the detection signal of any one of the light receiving elements 10b to 14b is detected, that is, when the light receiving element receives light from the light emitting element, an abnormal banknote such as a quadruple banknote is inserted. It is determined that the shutter 16 is kept open, the customer is notified and the banknote is returned. Moreover, when the detection signal of any element among the light receiving elements 10b to 14b is not detected, it is determined that the bill A is inserted in a normal state, and the bill press 1 is moved in the pool part 3 and stage 2 directions. After the banknote A is clamped, the rotation unit 4 is rotated about the rotation axis, and is stopped at the feeding position inclined approximately 90 degrees counterclockwise in FIG.

  As shown in FIG. 5, a part of the feed roller 7 protrudes from the stage 2 and abuts against the bill A in a state where the rotating unit 4 is stopped at the feeding position. When the feed roller 7 is rotated, the bills A are fed one by one in the direction of the feeding roller 5 and taken into the apparatus by the feeding roller 5 and the gate roller 6. When the loading of the bill A is completed, the turning unit 4 is turned approximately 90 degrees clockwise to return to the standing state of FIG. 1 and the bill press 1 is retracted to complete the deposit.

  The operation at the time of withdrawal will be described with reference to FIGS. 6 (a) to 6 (f) and FIG. In response to an instruction from the control unit, the rotating unit 4 rotates from the standing position around the rotation axis, and the rotating unit 4 is directed to the extended position as shown in FIG. After that, the bill press 1 is raised from the initial position close to the stage 2 and the pool section 3 in the direction of the arrow X1 and then in the X2 direction to become a wall that regulates the upper side of the accumulation space of the rotating section 4 To stop. Subsequently, following the stop of the bill press 1, the stage 2 is raised. The stage 2 is at the position P1 in FIG. 7, that is, the initial position almost in contact with the pool portion 3 immediately before ascending. When the stage 2 is lifted from the position of P1, the optical axes of the light emitting elements 12a to 14a and the light receiving elements 12b to 14b are immediately crossed. At this time, first, the light shielding elements 2a and 13b of the light emitting elements 13a and 13b are blocked by the shielding portion 2a of the stage 2. The optical axis is blocked. By further rising, the optical axis between the light emitting elements 12a to 14a and the light receiving elements 12b to 14b is subsequently blocked by the entire plate-like member of the stage 2. It goes without saying that the light emission of the light emitting element or the detection of the light receiving element may be ignored under the control of the control unit.

  In the present invention, the light emission of the light emitting element or the detection of the light receiving element by the control of the control unit is not necessarily essential. However, based on the detected signal, for example, the detection timing of the light receiving element 13b and the detection timing of the light receiving elements 12b and 14b. If the time lag is equal to or greater than a predetermined time set in advance, it is determined that the bill A is not accumulated on the stage 2 that is currently rising, and the presence status of the bill A on the stage 2 is detected. Is possible. The data regarding the presence or absence of the bill A thus obtained can be fed back to various controls such as bill preparation and feeding operation in the apparatus.

  After the stage 2 reaches the position P2 in FIG. 7, it passes between the light receiving element 10a and the light emitting element 10b and between the light receiving element 11a and the light emitting element 11b as shown in FIG. Are simultaneously turned off. A control part determines with the signal from a light receiving element having reached the delivery position of the banknote A, and the stage 2 is stopped. At this time, since the light emitting elements 10a and 11a are disposed in the vicinity of the blade portion 8b, the stage 2 is correctly positioned at a height near the tip of the blade portion 8b.

  Thereafter, as shown in FIG. 6C, the control unit lowers the stage 2 in the arrow Y direction by a preset amount to form a space in which the bills A are stacked. Then, the stacking roller 8 and the gate roller 9 are rotated to feed the bills A one by one on the stage 2. Thereby, the bill A is hit on the rear end portion by the blade portion 8b and falls onto the stage 2 and is accumulated. If the stacking operation of banknotes is repeated by the number of sheets designated by the customer, the height of the stacked banknotes A is gradually increased, and the stacked banknotes A as shown in FIG. And the optical axis between 11b is blocked. As a result, the detection signals of the light receiving elements 10b and 11b are turned off. Upon receiving the OFF signal, the control unit determines that the space for stacking the bills A is insufficient. Subsequently, as shown in FIG. 6E, the stage 2 is lowered by a predetermined amount in the direction of the arrow Z in accordance with an instruction from the control unit to form an accumulation space. By this control, the position of the discharge port of the bill A is always kept at a constant height with respect to the uppermost surface of the stacked bill.

  When the above-described stacking operation is repeated and the banknotes A are stacked until reaching a predetermined maximum capacity as shown in FIG. It is shielded and the detection signal is turned off. The control unit receives the OFF signal, determines that it is the maximum accumulation amount, and ends the accumulation of banknotes. When the bill accumulation is completed, the bill press 1 is lowered onto the stage 2 to press the bill A and descend onto the pool portion 3 to sandwich the bill A, and then the rotating portion 4 is moved forward of the bill depositing / dispensing machine. Rotate to stand. Further, after the bill press 1 is retracted, the shutter 16 is opened so that the customer can receive the bill A from the customer service port 15.

  In the above-described embodiment of the present invention, the light emitting elements 10a to 14a and the light receiving elements 10b to 14b are used to detect the presence of the banknote A in the rotating unit 4. May be controlled so as to be constantly monitored during the transaction of the customer, and abnormal withdrawal of the banknote A may be detected.
