The movement stroke is such that the coin is pulled out by about 2/3 from 07, and the coin is dropped down from the round hole 120 by pulling out the coin by 2/3 from the holding cylinder 102. In this case, when the change slider 118 is not restricted by the stopper pin of the selection device, the upper and lower sliders 116,
The coin moves along with 117 and is dropped from the round hole 120, but when the coin is regulated by the stopper pin, the coin does not move and acts to close the round hole 120 so that the dropping of the coin is prevented. Has become.

On the other hand, the wiper 115 has a base end with the lower cover 1
06 is engaged with a long groove 122, and an intermediate portion is rotatably supported by a pin 123 protruding from the lower surface of the lower slider 117, and is interlocked with the reciprocating movement of the slider body 114. The lower cover 106 is irregularly rotated between a position facing the front-rear direction and a position facing the left-right direction. That is, in this conventional example, of the five holding cylinders 102,
The coins of the four holding cylinders 102 are paid out by the reciprocating movement of the slider body 114, and the coins of the remaining rightmost holding cylinder 102 are once dropped onto the lower cover 106 and then paid out by the rotation of the wiper 115. Be done.

The receiving plate portion 125 into which the coins of the right end holding cylinder 102 are dropped is provided, and the receiving plate portion 125 has a wiper 115.
A guide wall 126 is formed along the rotation trajectory of the.

Next, referring to FIGS. 10 to 12, the change-out operation will be briefly described. The case of paying out coins from the holding cylinder 102 at the right end in the drawing by a change command will be described as an example. First, the motor 110 of the drive device 104 starts rotating, and at the same time, the holding cylinder at the left end of the stopper pins of the selection device. Other stopper pins project except the stopper pin corresponding to. When the rotation of the motor 110 progresses, the top 113 moves the slider body 114 backward from the steady state of FIG. 10, and the wiper 115 is rotated to the lateral position via the slider body 114. With the forward movement of the slider body 114, the slide protrusion 121 of the slider body 114 operates so as to catch the coin at the bottom and pull it out from the slit 107 of the storage cylinder 102 rearward. At this time, due to the action of the stopper pin of the selection device, the change slider 1 corresponding to the right end holding cylinder 102
Only 18 moves with both upper and lower sliders 116 and 117,
The other change slider 118 is left partially flush with the bottom plate of the storage cylinder 102. Therefore, only the coin in the holding cylinder 102 at the right end is opened by the opening 1 of the bottom base 103.
09 is dropped into the receiving plate portion 125 of the lower cover 106 (state of FIG. 11).

As the motor 110 further rotates, the slider body 114 shifts from the forward movement to the backward movement by the action of the top 113, and the holding cylinders 102 other than the rightmost holding cylinder 102 are once pulled out from the slit 107 to the middle. Return the coins to their original position. At the same time, the coin dropped from the holding cylinder 102 at the right end is rotated by the wiper 115,
As it is flipped, it is dropped into the dispensing port 124 (state of FIG. 12). It should be noted that coins dropped from the holding cylinders 102 other than the holding cylinder 102 on the right end are the slider body 1
When 14 moves forward, it is directly dropped into the payout opening 124.

[0011]

In such a conventional coin processing apparatus, the cam mechanism for reciprocating the slider 105 includes a rotating cam projection 121 and a one-character cam groove 1.
Therefore, in the reciprocating operation of the slider 105, the forward movement to the backward movement is continuously performed (see the cam displacement curve B in FIG. 3). Therefore, when the payout speed of coins is increased, the coins to which water or the like adheres are taken in by the slider 105 moving backward with a momentary delay in the timing of falling from the round holes 120 of the slider 105, or the slide protrusions of the slider 105. There is a problem that 121 hits the edge of the coin. In the case of the payout by the wiper 115, the slider 10
The coin dropped from the round hole 120 of 5 is the lower cover 1
When bouncing on the backing plate 125 of 06, the wiper 11
There is a problem that 5 passes under the coin. In such a state, the coin is dispensed incorrectly, the device is damaged, the coin is clogged, and the like, so that the coin dispensing speed is limited.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a coin payout device that can reliably pay out coins even if the payout speed is increased.

[0013]

In order to achieve the above-mentioned object, the invention of claim 1 is such that a holding cylinder for holding coins in a stacked state, and a coin formed in the lower end of the holding cylinder so that the coins inside the holding cylinder are located laterally. An opening capable of being drawn out, a payout opening continuous to the opening, a slide member facing the lower end of the holding cylinder and reciprocating in the radial direction of the holding cylinder, and a reciprocating means for reciprocating the slide member. In the coin payout device configured to move the slide member forward by the reciprocating means, pull out the coin in the holding cylinder through the opening by the slide member, and drop the coin into the payout opening, the reciprocating means is It is characterized by having a temporary stop mechanism for temporarily stopping the movement of the slide member at the time of shifting from the forward movement to the backward movement.

Further, according to the invention of claim 2, a holding cylinder for holding the coins in a stacked state, a coin receiving portion for receiving coins dropped from the holding cylinder, and a payout provided at an extended end of the coin receiving portion. A wiper member facing the mouth and the coin receiving portion and reciprocally movable between a return position and a payout position, a reciprocating means for reciprocating the wiper member, and a holding cylinder inside when the wiper member moves forward. And a dropping means for dropping the coin into the coin receiving part, and the reciprocating means moves the wiper member forward to the payout position and then returns to the return position so that the coin on the coin receiving plate is moved by the wiper member. In the coin payout device that draws in and draws the coins into the payout opening, the reciprocating means has a temporary stop mechanism that temporarily stops the movement of the wiper member at the time of transition from forward movement to backward movement. To.

In these cases, the suspension mechanism is preferably a cam mechanism having a chevron-shaped displacement curve with a flat top.

[0016]

According to the coin payout device of the present invention, when the slide member is moved forward by the reciprocating means, the slide member pulls out the coin in the holding cylinder through the opening and drops it into the payout opening. , Then the slide member is returned,
Return to the original position. In this case, the reciprocating means has a temporary stop mechanism for temporarily stopping the movement of the slider member moving from the forward movement to the backward movement, so that the coin drops into the opening even if the reciprocating speed of the slider member is increased. Sufficient time can be secured.

Further, according to the coin payout device of the second aspect, when the wiper member is moved forward to the payout position by the reciprocating means, the coin in the storage cylinder is dropped onto the coin receiving plate by the dropping means. When the wiper member is inserted and then returned to the return position, the wiper member draws the coin on the coin receiving plate and drops it into the payout opening. In this case, since the reciprocating means has a temporary stop mechanism for temporarily stopping the movement of the wiper member moving from the forward movement to the backward movement, even if the movement of the wiper member is accelerated, it is dropped on the coin receiving plate. It is possible to secure enough time for the bound of coins to settle down.

In these cases, by constructing the temporary stop mechanism by a cam mechanism having a mountain-shaped displacement curve having a flat top, play can be reduced and the slider member or wiper member can be stopped reliably. .

That is, when the motor 41 is driven, both the tops 43, 43 rotate simultaneously, and the slider 12 reciprocates once for each rotation of the tops 43, 43.

The selection device 11 includes five solenoids 51, 51, 51, 51, 51 corresponding to the holding cylinders 7a, 7b.
And five stopper pins 52, 52, 52, 52, 52 that move up and down in the vertical direction by the respective solenoids 51. The tip of each stopper pin 52 penetrates each of the small holes 37 of the bottom base 9 and projects downward from the bottom surface of the bottom base 9 by the excitation and demagnetization of the solenoid 51. When the stopper pin 52 projects,
When the change slider 65 is engaged with the rear end of the change slider 65, which will be described later, to restrict the movement of the change slider 65, and when the change slider 65 is retracted, it acts to release this restriction. That is, based on the change command, the solenoid 51 is selectively excited to immobilize the specific change slider 65 against the movement of the slider 12, thereby preventing the change other than the desired denomination from falling. It has become. .

The slider 12 is composed of a slider body 61 and a wiper (wiper member) 62 that rotates in conjunction with the slider body 61. The slider body 61 has an upper surface of the receiving portion 32 of the bottom base 9 having a step,
The wiper 62 is provided so as to be inserted between the lower surface of the attachment portion 33 and the lower surface of the slider body 61 and the upper surface of the lower cover 13.

A case where a 0-yen coin is paid out will be described as an example.

First, in response to a change command, the motor 41 of the drive unit 10 starts rotating, and at the same time, the other stopper pins of the stopper pin 52 of the selection unit 11 except for the stopper pin 52 corresponding to the preliminary holding cylinder 7b. 52 projects. When the rotation of the motor 41 progresses, the tops 43, 43 move the slider body 61 backward via the reduction gear train 42, and the wiper 62 rotates to the lateral position (discharging position) via the slider body 61. To be done. With the forward movement of the slider body 61, the slide projection 68 of the slider body 61 operates so as to catch the coin at the lowermost position and pull it backward from the slit 22 of each of the holding cylinders 7a and 7b. At this time, the stopper pin 52 of the selection device 11
By this action, only the change slider 65 corresponding to the spare holding cylinder 7b moves backward together with the upper and lower sliders 63 and 64, and the other change sliders 65 are left in a stationary state. As a result, only the coins of the preliminary storage cylinder 7b are dropped from the opening 34 of the bottom base 9 onto the receiving plate portion 83 of the lower cover 13 (see FIGS. 5 and 8).

Further, as the rotation of the motor 41 progresses, the slider body 61 and the wiper 62 are temporarily stopped by the action of the top 43, and then move from the forward movement to the backward movement. When the slider body 61 moves back, the holding cylinders 7 other than the preliminary holding cylinder 7b are
At a, the coin once pulled out halfway (about ⅔ of the coin diameter) from the slit 22 is supported by the change slider 65 and returns to the original position. That is, the coin is moved backward by the slider body 61, but is returned to the original position without being dropped.
On the other hand, the coin dropped from the preliminary storage cylinder 7b is guided to the guide wall 84 by the rotation (returning) of the wiper 62 accompanying the backward movement of the slider body 61, and is flipped to the payout opening 14. Dropped (see Figure 6). The coins dropped from the holding cylinders 7a other than the preliminary holding cylinders 7b are dropped into the payout opening 14 directly or through the inclined portion 82 of the lower cover 13 when the slider body 61 moves forward.

As described above, according to this embodiment, the reciprocating slider body 61 and the wiper 62 interlocking with the slider body 61 are temporarily stopped when the cam mechanism shifts from the forward movement to the backward movement. Because I am
It is possible to secure a time for the coin to separate from the slider body 61 and fall into the payout opening 14 of the lower cover 13 or the receiving plate portion 83. That is, even with coins to which water or the like adheres, it is possible to secure a sufficient time for the coins to fall, and also a sufficient time for the bouncing of coins dropped on the receiving plate portion 83 to converge. Therefore, even if the payout speed is increased, the coins can be paid out with certainty.

Further, since the solenoid 51 is provided so as to correspond to each change slider 65, the responsiveness is improved and a complicated power transmission between the solenoid 51 and the change slider 65 as in the conventional case is performed. There is no need to provide a mechanism, and a simple structure can be used with few failures.

In this embodiment, the coin payout device has been described, but it goes without saying that the present invention can be applied to coin payout devices used for game machines and the like as well as currency exchange machines. Further, although the cam mechanism using the opposite cam is used as the temporary stop mechanism, it is also possible to replace it with another cam mechanism (positive cam) having the displacement curve of FIG. A link mechanism or the like can be used instead of the cam mechanism.

[0042]

As described above, according to the coin payout device of the present invention, the reciprocating slide member or wiper member is
Since it is stopped once when moving from the forward to the backward movement, it is possible to secure enough time for the coin to drop in and the time for the coin to bounce to settle, and the coin to be paid out reliably. . Therefore, the coin payout time can be shortened accordingly.
