And a payout slide 7 for pulling out coins M stored and stored in the coin storage cylinder 5 one by one.

The coin dispensing unit 3 includes a disk-shaped motor cam (not shown) that is rotated by a drive motor (not shown), a link 8 that reciprocally slides in the left-right direction in FIG. 1 in conjunction with the motor cam, A change slide 9 provided for each coin storage cylinder 5 and selectively supporting the lower surface of the coin M pulled out from the payout slide 7 and releasing the coin M to control the dispensing and non-dispensing of the coin; a coin selection solenoid 10 for determining the movement whether 9, adjacent to the coin holding cylinder 5 back (right side in the figure in the direction. similarly referred to as "coin yield capacity barrel 5 back" hereinafter), drawn by the payout slide 7 coins A coin confirmation sensor 11 for detecting M is provided.

  The link 8 and the payout slide 7 are connected to each other when the coin accommodating portion 4 is mounted on the housing 2 and are connected to each other by recesses and projections, and the payout slide 7 is linked to the motor cam (not shown) via the link 8. Then, the reciprocating sliding movement is made along the coin base 6 in the horizontal direction of the drawing in FIG.

  The drive motor (not shown) and the payout coin selection solenoid 10 are driven based on a coin payout command or the like from a control device (not shown), respectively, and a coin payout operation and a specific denomination in each coin storage cylinder 5 are provided. Only paying out and controlling.

  As described above, the basic configuration of the coin dispensing device 1 according to the present invention is the same as the configuration of the coin processing device disclosed in Japanese Patent Application No. 2009-162817, but in the present invention, the shape of the change slide 9 is the conventional one. It is very different from the thing.

  As shown in FIGS. 2A, 2B, and 2C, the change slide 9 has a coin placing portion 9a that supports a part of the lower surface of the coin when the coin is pulled out, and a tip of the change slide 9, as shown in FIGS. And an inclined portion 9b formed.

  The coin placement portion 9a is provided in the entire width of the change slide 9, and the upper surface thereof is formed in a horizontal plane, and in a state where the change slide 9 is in the coin payout position, the coin placement portion 9a is in a range that does not hinder the coin fall. It is formed in a size (see FIG. 6B).

  In addition, the inclined portion 9b is provided in the entire width of the change slide 9 similarly to the coin placement portion 9a, and as shown in FIG. 3, the tip of the change slide 9 with respect to the coin base 6 in the standby state. Is formed with substantially the same inclination as the inclined portion 6b of the coin base 6 so that a part of the coin base 6 overlaps in the vertical direction.

  The operation of each part of the change slide 9 when paying out coins will be described in detail later.

With the above structure, in FIG. 4, as a partial overlapping the coin base 6 of the change slide 9 in the vertical direction by a broken line, in the standby state, a coin base 6 change slide 9 is in the lower surface of the coin revenue volume cylinder 5 And an arc-shaped gap between the payout slide 7 and the substantially entire region of the arc.

  In this way, by avoiding a gap as much as possible between the coin base 6 and the change slide 9, as shown in FIG. 5, even when the coin storage cylinder 5 is empty, The coin base 6 is normally stored in the lowermost layer of the coin storage cylinder 5 without being caught between the coin base 6 and the change slide 9.

  As described above, the coin placing portion 9a of the change slide 9 supports a part of the lower surface of the coin when the coin is pulled out by the payout slide 7, and the change slide 9 is in the coin payout position. Is formed so as not to obstruct the falling of the coins, the size of the coin mounting portion 9a does not necessarily have to be such a size as to block all the payout holes 6a (see FIG. 6A etc.), and is drawn out. As long as there is a range that supports the lower surface of a part of the coin, a rectangular plane may be used as shown in FIGS. 2A, 2B, and 2C.

  As shown in FIG. 4, even if the change slide 9 side is linear with respect to the arc shape of the coin base 6, the tip of the falling coin is prevented from advancing by the inclined portion 9 b of the change slide 9. It rotates without being caught by the coin base 6 or the change slide 9 and is normally stored.

  Next, the coin dispensing operation in the coin dispensing apparatus 1 of the present application will be described, and the operation of the change slide 9 of the present invention will be described in more detail.

  The payout coin selection solenoid 10 is driven in response to a command from a control device (not shown), and a motor cam (not shown) is driven so that the payout slide 7 and the change slide 9 are connected to the back side of the coin storage cylinder 5 via the link 8. The coin M in the coin storage cylinder 5 is pulled out by sliding in the direction.

  As shown in FIG. 6A, when the coin M pulled out by the payout slide 7 is moving on the coin base 6, the coin placement portion 9a of the change slide 9 supports a part of the lower surface of the coin M. Therefore, the coin M arrives directly below the coin confirmation sensor 11 and is detected by the coin confirmation sensor 11 while being held in a horizontal posture by the coin base 6 and the coin placement portion 9 a of the change slide 9.

  Then, the payout slide 7 further moves the coin M in the direction of the back side of the coin storage cylinder 5 while maintaining the posture of the coin M horizontally by the coin base 6 and the coin placement portion 9a of the change slide 9.

  As shown in FIG. 6B, when the coin M is completely pulled out by the payout slide 7, the coin M is detached from the coin base 6, starts to fall from the front side of the coin receiving cylinder 5, and the coin confirmation sensor 11 dispenses the coin. Detect.

At this time, the coin mounting portion 9a of the change slide 9, in a range that does not inhibit the fall of the coin M, so as to remain closes the part of the coin revenue capacity barrel 5 back direction of payout hole 6a, reliably coin The falling direction of the coin is regulated so that the coin M starts to fall from the front side of the housing cylinder 5.

  At the same time, the coin M is guided in the dropping direction by the inclined portion 9b formed at the tip of the change slide 9.

  Thereafter, the operation continues, the link 8, the payout slide 7 and the change slide 9 return to the standby position shown in FIG. 1, and the driving of the payout coin selection solenoid 10 and the motor cam (not shown) stops and returns to the standby state. .

  When the coin M is paid out, the payout slide 7 pulls out the coin M and reaches the coin payout position shown in FIG. 6B in order to surely detect the coin M by the coin detection sensor 11 and to drop and pay out the coin M. At this time, a time during which the operation of the payout slide 7 is stopped may be provided.

  When coins are not paid out, the payout coin selection solenoid 10 does not operate and the change slide 9 is maintained at the standby position, while the link 8 and the payout slide are used to pay out coins in other coin cylinders 5. 7 moves in the reverse direction of the coin cylinder 5, the payout slide 7 pulls out the coin M, and the coin confirmation sensor 11 detects the coin M.

  The payout slide 7 further moves the coin M in the direction of the back side of the coin cylinder 5 to the coin payout position shown in FIG. 5B, but the change slide 9 supports the lower surface of the coin M and restricts the falling of the coin M. M is not paid out.

  Thereafter, the link 8, the payout slide 7, and the coin M continue to move in the direction toward the front side of the coin cylinder 5 and return to the standby position shown in FIG.

  As described above, in the coin dispensing device of the present invention, in the standby state, the gap between the coin base and the change slide is made as small as possible, and at the time of coin dispensing, the coin pulled out to the payout slide is coin dispensed. The horizontal posture is maintained until the position is reached.

Thus, the present invention provides a coin drawn from the coin yield capacity cylinder reliably detect composed coin confirmation sensor provided on the back side coin yield capacity barrel, without payout trouble occurrence of the coin falling easily, Coins that can be realized with the same parts configuration as before, without adding new parts, changing the configuration of peripheral parts, or increasing the overall size of the coin processing device, and thus enabling mass production A dispensing device can be provided.
