Here, FIG. 4 shows a coin chute 30 in which a coin input port 33 on the front surface of the second door 3 is connected (cooperated) with a coin recognition device 37 mounted on the back surface of the second door 3 . The coin chute 30 is a component that constitutes a coin guide passage that accepts coins inserted in a horizontal posture from the coin insertion opening 33, slides the coin down from the downwardly inclined slope, and then passes through the coin guide passage. The plumb part converts the orientation to a plumb pose. The coin chute 30 is composed of a lower frame 301 made of resin forming the inside of the coin guide passage, and an upper guide member 302 made of metal plate that closes (encloses) the outside of the coin guide passage. In addition, in Fig. 4 (a), (b), the part indicated by the reference numeral 340 is connected with the rear end of the coin return handle 34, and it is returned in cooperation with the opening part 371 which makes the coin sorting machine of the coin identification device 37 open. Operating parts.

The lower frame 301 is formed with a slit 301a that discharges rainwater that intrudes from the coin inlet 33 into the sliding surface of the aqueduct-shaped coin guide passage, and is formed with a slit 301a that collects the rainwater discharged through the slit 301a and makes it flow to the second floor. The drain channel that the back side of the door 3 emits. This coin chute 30 is fixedly installed on the door frame of the second door 3 by utilizing the screw S1 lower frame 301 so that the entrance part is opposed to the coin input port 33, and the exit part is in the funnel-shaped coin receiving port of the coin recognition device 37. 370 face each other with a predetermined gap. The so-called predetermined gap is to make the coin receiving port 370 not against the coin chute 30 when the coin identification device 37 is installed and removed (the shaft of the lower end side of the coin identification device 37 is used as a fulcrum to rotate the upper end side to install and remove). There is a gap with more or less leeway. The coin chute 30 of this structure is widely known in the prior art. When there is a gap between the exit portion of the coin chute 30 and the funnel-shaped coin receiving port 370 of the coin identification device 37, the coin chute 310 The trajectory of the coin that enters the coin receiving port 370 of the coin identification device 37 is uncertain, so the coin released from the outlet of the coin slide 310 collides with the inner wall of the funnel-shaped coin receiving port 370, and there is a collision with the inner wall of the coin receiving port 370. A situation where a collided and bounced coin flies out of the coin receiving port 370 .

Therefore, a movable cover (movable guard) 310 is additionally attached to the exit portion of the above-mentioned known coin chute 30 . The movable cover 310 is made of a rectangular flat metal plate, and two sliding grooves 311, 311 extending in the vertical direction are formed on the plate surface, and a finger touching portion (finger hooking portion) 312 is formed on the upper end. The upper guide member 302 of the coin chute 30 is fixed with a mounting metal member 303 having a vertical surface 303 a so that the movable cover 310 is vertically slidably attached to the exit portion of the coin chute 30 . On the vertical surface 303a of the mounting metal member 303, tapped holes are formed for screwing the two stepped screws 321, 322. The stepped screws 321 , 322 are screwed to the vertical surface 303 a of the mounting metal member 303 through the slide grooves 311 , 311 of the movable cover 310 . Here, the sliding grooves 311 , 311 of the movable cover 310 are formed to have a width larger than the diameter of the trunk portion of the stepped screws 321 , 322 and smaller than the diameter of the heads of the stepped screws 321 , 322 . Furthermore, the movable cover 310 is formed of a metal plate having a thickness (plate thickness) smaller than the height of the stems of the stepped screws 321 and 322 . Therefore, in the state where the movable cover 310 is mounted on the mounting metal member 303 by the stepped screws 321, 322, the upper edge of the sliding grooves 311, 311 of the movable cover 310 is in contact with the stepped screws 321, 322 due to its own weight. It hangs down to the lowered position, and freely shakes and displaces. In this case, the positions of the slide grooves 311, 311 and the lengths in the up-down direction are determined in such a way that the lower end of the movable cover 310 hanging down to the lowered position extends at least to the upper end of the coin receiving opening 370 of the coin discriminating device 37, In addition, the lower end of the movable cover 310 where the finger touch portion 312 is raised to the raised position by attaching a finger to the finger touch portion 312 is located at least at the lower end of the exit portion of the coin chute 30 .

The movable cover 310 of this structure is installed at the exit portion of the outer side of the coin chute 30 in a manner to be slidable in the vertical direction, and in the normal state of hanging down to the lowered position, the exit portion of the outer side of the coin chute 30 is The gap with the coin acceptance opening 370 of the coin recognition device 37 is closed. As a result, when the coin discharged from the exit portion of the coin chute 310 collides with the movable cover 310, the movable cover 310 is rocked and displaced, thereby absorbing the impact force. Thereby, the coin colliding with the movable cover 310 does not bounce back largely and falls downward, and is collected in the coin receiving opening 370 of the coin identification device 37 . On the other hand, when the coin ejected from the outlet of the coin chute 310 collides with the inner wall of the coin accepting port 370 of the coin identification device 37 on the opposite side of the movable cover 310 and bounces back, the coin will collide with the movable cover 310. The cover 310 collides and the impact force is absorbed and falls downward, and is collected in the coin receiving port 370 of the coin discriminating device 37 . Therefore, only by installing the movable cover 310 in the exit portion of the outer side of the coin chute 30 to slide freely in the vertical direction and to change the position, it is possible to prevent coins from passing through the exit portion of the coin chute 30 and the coin identification device 37. Fly out of the gap between the funnel-shaped coin receiving openings 370 . In addition, when installing and removing the coin identification device 37, it is only necessary to carry out the coin identification device on the basis of attaching the finger to the finger touching part 312 of the lowered movable cover 310 and raising the finger touching part 312 to the upper limit position. 37 can be installed or removed.
