Abstract

PURPOSE:To miniaturize the title device by guiding coins in two coin housing cylinders, which are placed in parallel forward and backward, to a paying out part by a sliding plate to move forward and backward. CONSTITUTION:Coins C1 housed in a forward positioned coin housing cylinder 2a are paid out by the first half reciprocating motion of a sliding plate 4, and coins C2 housed in a backward positioned coin housing cylinder 2b are paid out by the second half reciprocating motion of the sliding plate 4 selectively by controlling the forward rotation and the backward rotation of a motor 37 by a control part 10. Namely, for example, when a rotary plate 34 is rotated counterclockwise from the stand-by state of the paying out of the coins, the sliding plate 4 successively shifts to a paying out state, first, one coin C1 housed in the forward positioned coin housing cylinder 2a is paid out, the sliding plate 4 continuously successively shifts from the paying out state and returns to its previous state. Consequently, two coins can be paid out whenever the sliding plate 4 is actuated for one reciprocation within the range of all the strokes by rotating the rotary plate 34 once. Thus, the device can be miniaturized.

Then the coin is on the top of the slide board! ! ! When dispensing coins stored in the coin storage tube from the coin dispensing standby state, the motor rotates in response to a dispensing command signal, the tilting lever tilts back and forth, and the slide plate horizontally moves back and forth. When the slide plate moves forward and its drop-in hole matches the front coin storage cylinder, a coin fits into the drop-in hole of the front coin storage cylinder, and this coin is transferred to the slide plate. When the coin recedes and the drop hole returns to the intermediate position between the two coin storage tubes, it is ejected and guided to the payout section, and then the slide plate moves rearward and the drop hole and rear coin storage tube align. When this happens, one coin in the rear coin storage tube fits into the drop-in hole, and when the slide plate moves forward and the drop-in hole returns to the intermediate position between both coin storage tubes, the coin is transferred to the payout section. guided by.

In addition, in the above, the slide plate (4)
It is also possible to drive and control the motor (37) so that the motor (37) reciprocates over the entire stroke range without distinguishing between the first half and the second half of the reciprocating motion. The coins stored in 2) a and (2) b are alternately dispensed. Like this, the front and rear coin storage tubes (2) a
, (2) As another means for alternately dispensing the coins stored in b, a rotating plate (
This can also be done by rotating 34) in only one direction. That is, for example, when the rotary plate (34) is rotated counterclockwise from the coin dispensing standby state shown in FIG. 1, the slide plate (4) sequentially shifts from the state shown in FIG. 2 to the states shown in FIGS. 3 and 4. Then, one coin C1 stored in the front coin storage tube (2) a is dispensed, and then the slide plate (4)
