A medal conveying guide 60 provided on the rear side in the rotational direction pushes the circumference of the medal and conveys it clockwise.

As shown in FIG. 8 and JSQ diagram, in this embodiment, the medal storage hole 59 that stores the medal 43
When the medal a reaches the position of the entrance 63 of the medal guideway 62, the medal 43 stored in the medal storage hole 59a is stored and arranged in the guide pin storage hole 64, as shown in FIG. The medal guide pin 73 is brought into contact with the medal guide pin 73.

That is, the medal guide pin 73 is configured to reciprocate within the medal guide pin storage hole 64 in the diametrical direction of the rotating disc part 52 in conjunction with the rotation of the rotating disc part 52, -1- As described above, this medal guide pin 73 is located at the innermost position of the medal guide pin storage hole 64 when each medal storage hole 59 is not at the position of the medal guideway population 63, and is located at the innermost position of each medal guide pin storage hole 64. Storage hole 59 is for medal guideway people +-
+63 position, it is configured to reach the outermost position.

Therefore, as described above, when the medal storage hole 59a storing the medal 43 reaches the medal taxiway population 63 position, the medal guide pin 73 is moved to the outermost side of the medal kite pin storage hole 64. Therefore, the medal 43 transported by the medal transport guide 60 comes into contact with the medal guide pin 73 marked 1-.

Thereafter, the rotary disk portion 52 further rotates clockwise, so that the front inner side of the medal is regulated by the two-legged medal guide bin 73, and the medal transport guide 6
0, the medal 43 is pushed from the rear inner side.

As a result, as shown in FIG. 9, the medal 43 is pushed by the medal conveying guide 60 with the front inner side of the medal 43 regulated by the medal daite pin 73, and is pushed by the medal guide path forming a medal guide portion. Side wall portion 65
The medal guideway 62 enters the medal guideway 62 while sliding in contact with the medal guideway 62.

Thereafter, the medal 43 is further pushed from behind by the medal conveying guide 60 as the rotary disk portion 52 rotates, so that the front side of the medal 43 comes into contact with the counter roller 61 . Therefore, as shown in FIG. 1O, in this case, the medal 43 is sandwiched between the medal guideway side wall 65 and the counter roller 61! It becomes i.

Then, like a double series, the counter roller 61 is
Inside the oval hole 80, the spring 66 is always biasing the rotating disk portion 52 in the counter-rotational direction. As the medal 43 enters the tip of the medal guide path 62, the counter roller 61 moves slightly upward in the oval hole 80 in FIG. 10 against the +Jtjj force described above.

Thereafter, the medal 43 is further pushed 1 2 toward the tip of the medal guideway 62 by the medal conveyance guide 60, and the contact point E between the medal 43 and the medal guideway side wall 65 and the J2 counter roller 61 are pushed. The medal 43 moves toward the tip of the medal guideway 62 until the length of the line G formed between the contact point F and the medal 43 becomes shorter than the diameter dimension 2 of the medal 43. When the medal 43 enters the medal guideway 62, the elastic force accumulated in the spring 66, which had been biasing the counter roller 61 in the counter-rotation direction of the rotating disk portion 52 by 4=j, acts. However, the counter roller 61 instantaneously moves within the oblong hole 80 in the direction opposite to the rotation of the rotating disk section 52, and attempts to return to its original position.

Therefore, the oblong hole 80 of this counter roller 61
Due to the return operation to the initial state inside, the medal 43 is suddenly pushed toward the tip of the medal guide path 62 by the resilient force of the counter roller 61, and as a result, the medal 43 is ejected. From part 57 to medal payout part 54
It is ejected outward.

Further, in this embodiment, as shown in FIG. 7, the medal 43 enters the medal guideway 62 and the counter roller 6
The distance dimension 1+ between the contact point A of the medal transport guide 60 with the medal 43 and the contact point B of the counter roller 61 with the medal 43 in the initial state in which the medal 43 is in contact with the medal 43 is larger than the diameter dimension of the medal 43. A counter roller 61 is disposed at the shortest position.

Furthermore, in this embodiment, the medal guide section 65 is formed at an acute angle α with respect to the tangent line set at the entrance 63 of the medal guide path 62 of the rotating disk section 52, and It is constituted by a side wall portion 65 that is continuous to the side wall portion 65.

Therefore, in the hopper type medal dispensing device 50 according to the present embodiment, due to various circumstances, the medals 43 may get caught between the medal ejection part 56 and the medal storage hole 59 in each medal storage hole 59, and the rotating disk part 52 stops rotating and it becomes impossible to eject the medals 43, operate the drive section 53 to rotate the rotating disk section 52 forward and counterclockwise in small increments. By reversing the medal, the medal 43 that is an obstacle is removed.

Even in such a case, as described above, the distance between the contact point A of the medal transport guide 60 with the medal 43 and the contact point B of the counter roller 61 with the medal 43 is 1゛υ,
In sentence 1, since the counter roller 61 is disposed at a position where the diameter of the medal 43 is shorter than the diameter Jv, when the rotating disk unit 52 repeats forward and backward rotation in small steps, the medal 43 is not ejected. The medal 43 is ejected outward from the portion 57 by the resilient force described in 1- above of the counter roller 61, or as shown in FIG.
The medal guiding path 6 is again moved by the medal transport guide 60b provided behind the medal storage hole 59b of the first ex-husband.
5, the medals are collected into the medal placement section 56.

Therefore, as in the past, the medal conveyance guide and the counter roller are located on the same line on the medal diameter line, and a so-called tension occurs, making it impossible for the rotating disk section 52 to rotate forward or backward. It is possible to prevent a situation where the medals 43 cannot be rotated and the medals 43 cannot be paid out.

Further, the rotating disk portion 52 used in the hopper-type medal dispensing device 50 according to this embodiment has a predetermined thickness dimension as described in I-, and each medal storage hole 59 has a larger number than the conventional one. Since the configuration is such that a number of medals 43 can be stored, the weight of the plurality of medals 43 loaded on the bottom medal 43 in each medal storage hole 59 is applied. , is placed in a stable posture on the medal placement section 56.

Therefore, as in the conventional hopper-type medal dispensing device, the medals 43 are placed between the medal placing section and the rotating disk section due to the unstable posture of the medals 43.
It is possible to effectively prevent the 1S condition in which the rotating disk portion 52 stops rotating due to the blockage.

5 6 [Effects of the Invention] The hopper-type medal dispensing device according to the present invention has the following configuration, and the drive unit is mounted on the base plate constituting the medal dispensing section of the hopper-type medal dispensing device. A heat radiating section is provided to conduct and radiate the heat generated by the operation.

Therefore, in the hopper-type medal dispensing device according to the present invention, the hopper-type medal dispensing device is located close to each other together with various other components such as a medal selector and a bill validator inside the slot machine, currency exchange, or vending machine. Even when the drive unit is installed in a state where the drive unit is operated, the heat generated by the operation of the drive unit is conducted to the heat dissipation unit extending from the base plate through the base plate to which the drive unit is attached, and is dissipated. Therefore, even if the hopper-type medal dispensing device is operated for a long time and the drive unit generates a large amount of heat, the heat will not be trapped inside the drive unit like in the past, and will be dissipated efficiently. Therefore, there is no fear that the operating efficiency of the drive unit will decrease, and it is possible for ITJ to consistently pay out medals stably even when the drive unit is operated for a long time.
