2. Description of the Related Art Conventionally, a coin dispensing machine constructed so that coins can be dispensed from a lower end portion of an upright coin storage cylinder having an inner diameter corresponding to a denomination coin by means of a payout piece movable in a horizontal direction has been proposed. As shown in Japanese Patent No. 5092, a coin shroud is pushed out by a delivery piece that reciprocates by rotating a motor-driven drive link back and forth to push a lowermost coin stored in a coin storage cylinder of each denomination.
It is known to discharge to a container and to discharge it to a pan below it.

[0003]

However, in this type of coin dispensing machine, coins are set and replenished in coin storage cylinders of denominations by hand.
If a different denomination coin smaller in diameter than the denomination coin to be stored is stored by mistake, or even if a coin depositing and dispensing machine is used, a denomination coin according to the coin storage cylinder is securely stored. Is not limited, and even if a different denomination coin having a smaller diameter than the denomination coin actually stored is stored, there is no means for discriminating it as a different denomination coin. When the processing is performed, the mixed coins of different diameters are also dispensed by the dispensing piece, so that an amount different from the designated withdrawal amount is dispensed, and the reliability is impaired. And so on. The present invention has been made in view of the above-described problem, and has as its object to reliably remove small-diameter coins mixed in a coin storage cylinder at the time of ejection.

[0004]

In order to achieve the above object, a first aspect of the present invention is to make it possible to effectively sort out mixed small-sized coins of a small diameter so that they can be reliably removed at the time of discharge. Yes, therefore, in a coin dispensing machine configured to be able to pay out coins by a horizontally movable payout piece from a lower end portion of an upright coin storage cylinder having an inner diameter corresponding to a denomination coin, the lower end side of the coin storage cylinder Between the discharge port and the upper receiving port of the shutter for receiving the coins of the specified denomination,
A width in which a horizontal guide member having a width equivalent to the diameter of the predetermined denomination coin is interposed, and a different denomination coin having a diameter smaller than the predetermined denomination coin can be dropped on the center bottom surface of the guide member. A narrow sorting hole is formed, a coin denomination coin storage portion is provided below the sorting hole, and the feeding piece is configured to be reciprocally driven so that the tip end thereof can move to the end side of the guide member. It is.

According to a second aspect of the present invention, the driving structure of the feeding piece and the inside of the machine are made compact so that the feeding piece can be effectively driven. Therefore, the feeding piece has a rack type meshing with a pinion capable of rotating forward and reverse. It is configured by setting.

In the third invention, coins of different denominations to be sorted can be more effectively and accurately removed from the sorting holes. Therefore, the coins are lightly pressed downward above the sorting holes. That is, a pressing member capable of performing the above-mentioned operation is provided.

[0007]

Therefore, when the coin at the lower end portion of the coin storage cylinder is pushed onto the guide member by the feeding piece movable to the terminal side of the guide member, coins of a predetermined denomination extend along the guide member while straddling the sorting hole. Sliding, it will be pushed out as it is and will be thrown into the shutter, and when a coin of small diameter is pushed out, it will not be able to straddle the sorting hole and will fall into the sorting hole, As a result, coins of a predetermined denomination are paid out to the shutter.

[0008] By forming and forming a rack which meshes with a forward and reverse rotatable pinion on the feed-out piece, the feed-out piece can be smoothly reciprocated by increasing the stroke to the end side of the guide member. Thus, the driving structure of the feeding piece can be reduced in size to have a compact structure, and the inside of the machine can be made compact without requiring a space by rotating the driving link as in the related art.

[0009] A pressing member for lightly pressing the coin downward is provided above the sorting hole, so that when a small-diameter coin of a small diameter to be sorted is looked into the sorting hole, the pressing member is pressed from above. Can be smoothly dropped into the sorting hole by light pressing.
