The left-right distance between the lower ends of both operation portions 86 is slightly smaller than the left-right distance between the inner surfaces of both locking pieces 35.

  Next, the basic operation of the banknote identification device described above will be described mainly with reference to FIG.

  When the rear chute 50 is in the closed position, the banknote transport unit 40 is in a state where the front and rear are sandwiched between the front chute 30 and the rear chute 50, and the upper curved portion 31 and the curved portion 51 of the rear chute 50 are Due to the presence, an inverted U-shaped banknote passage BP (see FIG. 3) is formed around the banknote transport unit 40. The front lower end of the banknote passage BP communicates with the rear end of the banknote insertion slot 61 via the curved portion 62 of the mask 60.

  When a banknote (not shown) such as a 1000-yen bill is inserted into the banknote insertion slot 61 of the mask 60 and the leading end reaches the detection area of the banknote insertion detection sensor 34, the both endless belts 43 of the banknote transport unit 40 are shown in FIG. The bill rotates in the clockwise direction, and the rotation causes the bill to be drawn into the inverted U-shaped bill passage BP and sent to the detection area of the bill recognition sensors 44 and 53 along the bill passage BP.

  The banknotes sent to the detection areas of the banknote identification sensors 44 and 53 are genuinely identified in the detection areas. If the banknotes are false, or both endless belts 43 of the banknote transport unit 40 cannot be identified in FIG. The bill is rotated clockwise, and the bill is returned to the bill insertion slot 61 from the inverted U-shaped bill passage BP.

  On the other hand, as a result of authenticity identification, in the case of a true banknote, a signal relating to insertion of a true banknote is output through a control circuit (not shown), and both endless belts 43 of the banknote transport unit 40 are rotated counterclockwise in FIG. The bill is fed to the rear side of the bill storage plate 21 of the base box 20 by the rotation. And the banknote storage plate 21 presses the cassette plate 72 of the banknote storage cassette 70 backward against the spring biasing force via the banknote, and the both edges in the width direction of the banknote ride over both rails 71 of the banknote storage cassette 70. After moving backwards, it returns to the front. By the operation of the banknote storage plate 21, the true banknote is stored so as to be sandwiched between the cassette plate 72 and the rails 71 of the banknote storage cassette 70.

  Next, the opening operation of the rear chute 50 in the above-described banknote recognition apparatus will be described mainly with reference to FIGS.

  The rear chute 50 is rotatably inserted into the left and right shaft support holes 23 of the base box 20 with the shaft portions 55 existing on the left and right sides of the lower rear side so that the rear chute 50 can be opened and closed by a rotating operation with the shaft support point as a fulcrum. Since it is attached to the base box 20, the rear chute 50 may be rattled due to the dimensional tolerance of the shaft portion 55 and the shaft support hole 23. Further, since plastic is generally used for the rear chute 50 in order to reduce cost and weight, the above-described rattling is likely to be noticeable due to the expansion and contraction due to the temperature change of the usage environment.

  However, as shown in FIG. 6, the rear chute 50 in the closed position is locked by inserting the pins 57 on the left and right sides into the locking holes 35 b of the locking pieces 35 on the left and right sides of the front chute 30. Since the position is held in the state, even when the back chute 50 before the blockage is rattled as described above, the rear chute 50 after the blockage is securely held at the proper closed position, and is in the closed position. There is no backlash or a position shift due to the backlash on a certain rear chute 50. In other words, the back chute 50 in the closed position can be reliably suppressed from causing a backlash that may hinder bill conveyance or the like, or a positional shift due to the backlash, and the bill can be accurately conveyed and the bill recognition sensor 44 can be used. , 53 can be accurately identified.

  When the rear chute 50 in the closed position is opened when checking or repairing the banknote transport unit 40, as shown in FIGS. 7 and 8, the pressing portion 81 of the locking release lever 80 is moved downward with a fingertip or the like. The two rod-like parts 85 and the two operation parts 86 are moved downward by pressing. Since the left and right intervals between the lower ends of both operation portions 86 of the unlocking lever 80 are slightly smaller than the left and right intervals between the inner surfaces of both engagement pieces 35, each of the operation portions 86 is brought into contact with each other by the downward movement caused by the pressing. A force that pushes them outward from the inclined surface 86a acts on the locking pieces 35, and the locking pieces 35 are elastically deformed outward so that the locking holes 35b come out of the pins 57 at the same time. Is released. Therefore, if the rear chute 50 is rotated rearward with the pivot point as a fulcrum in the unlocked state, the rear chute 50 is opened to expose the banknote transport unit 40 as shown in FIG. It is possible to perform the desired inspection or repair accurately by removing the banknote transport unit 40 from the front chute 30 as necessary.

  6 and 7 show the contact points of the respective locking pieces 35 with which the inclined surfaces 86a of the respective operation portions 86 are in contact with each other at an acute angle. As shown in FIG. If the inclined surface 35c or roundness (not shown) is formed on the inner surface, the operation when elastically deforming each locking piece 35 outward by the inclined surface 86a of each operation portion 86 can be performed more smoothly. It is also possible to reduce wear and damage at the mutual contact points.

  Next, the closing operation of the rear chute 50 in the above-described banknote recognition apparatus will be described mainly with reference to FIG.

  When the rear chute 50 after being opened is returned to the closed position, as shown in FIG. 11, the rear chute 50 may be rotated forward with the pivot point as a fulcrum. Each locking piece 35 can be deformed to the left and right by elasticity, and an inclined surface 35a is provided on the inner side of each rear end. Therefore, when the rear chute 50 is rotated forward with the pivot point as a fulcrum. The tip of each pin 57 comes into contact with the inclined surface 35a of each locking piece 35, and a force that pushes each locking piece 35 outward by the mutual contact acts to elastically deform each locking piece 35 outward. When the rear chute 50 reaches the closing position, as shown in FIG. 4, the pins 57 are inserted again into the locking holes 35 b of the locking pieces 35 and locked to properly close the rear chute 50. Held in position.

  In FIG. 11, the contact portion of each pin 57 with which the inclined surface 35 a of each locking piece 35 contacts is shown at an acute angle, but if the contact portion of each pin 57 is rounded (not shown), The operation at the time of elastically deforming each locking piece 35 outward by each pin 57 can be performed more smoothly, and the wear and damage of the mutual contact portion can also be reduced.

  Thus, according to the banknote identification device described above, the pins 57 on the left and right sides of the rear chute 50 are inserted and locked in the locking holes 35b of the locking pieces 35 on the left and right sides of the front chute 30, respectively. Since the rear chute 50 is held at the closed position, the rear chute 50 after being closed is securely held at the proper closed position even when the rear chute 50 before the blockage is rattled. The back chute 50 at the position does not play back and no position shift due to the backlash occurs. In other words, the back chute 50 in the closed position can be reliably suppressed from causing a backlash that may hinder bill conveyance or the like, or a positional shift due to the backlash, and the bill can be accurately conveyed and the bill recognition sensor 44 can be used. , 53 can be accurately identified.

  Further, according to the above-described banknote identification device, the locking holes 35b of the locking pieces 35 are moved rearward by elastically deforming the locking pieces 35 on both the left and right sides of the front chute 30 by operating the locking release lever 80. Since the locking can be released by simultaneously extracting from the left and right pins 57 of the side chute 50, the rear chute 50 can be opened with a simple operation.

  Furthermore, according to the banknote identification device described above, the one having the operation portions 86 on both the left and right sides for elastically deforming the locking pieces 35 on both the left and right sides of the front chute 30 outward simultaneously is used as the locking release lever 80. Since the operation portion 86 is provided with an inclined surface 86a suitable for pushing the locking pieces 35 outward, the locking releasing operation by the locking releasing lever 80 can be accurately performed.

  Furthermore, according to the banknote identification device described above, the inclined surfaces 35a that can come into contact with the tips of the pins 57 on the left and right sides of the rear chute 50 are provided inside the rear ends of the locking pieces 35 on the left and right sides of the front chute 30. Therefore, the tip of each pin 57 of the rear chute 50 is brought into contact with the inclined surface 35a of each locking piece 35 by simply returning the rear chute 50 after opening to the closed position. Each of the locking pieces 35 is elastically deformed to the outside, and when the rear chute 50 reaches the closed position, each pin 57 can be reinserted into the locking hole 35b of each locking piece 35 and locked. Similarly, the rear chute 50 can be reliably held at an appropriate closed position.

  In the banknote identification device described above, each pin 57 of the rear chute 50 is inserted and locked into the locking hole 35b of each locking piece 35 of the front chute 30, but the locking hole 35b is connected to the pin 57. Is replaced with a non-through hole or groove that can be locked, or the pin 57 is replaced with a locking protrusion of another shape having a shape that can be locked into the locking hole 35b or the non-through hole or groove. However, it is possible to perform the same locking and unlocking as described above.

  Further, in the above-described banknote recognition device, each locking piece 35 of the front chute 30 is provided with the inclined surface 35a that can come into mutual contact with each pin 57 when the rear chute 50 is closed. Even if the inclined surface is eliminated and an alternative inclined surface is provided on each pin 57, the same effect as described above can be obtained.

  Furthermore, in the banknote identification device described above, the locking piece 35 is provided on the front chute 30 and the pin 57 (locking protrusion) is provided on the rear chute 50, but the pin 57 (locking protrusion) is provided on the front chute 30. Even if the locking piece 35 is provided on the rear chute 50, it is possible to obtain the same effect as described above.

  Furthermore, in the banknote identification device described above, each operation portion 86 of the lock release lever 80 is provided with an inclined surface 86a so that when the lock is released, each lock piece 35 is pushed outward by the inclined surface 86a. However, even if the inclined surface 86a is eliminated from each operation part 86 and an alternative inclined surface is provided on each locking piece 35, the same effect as described above can be obtained.
