By the way, in the conventional coin returning device 3, since the returning lever 32 is used for the returning operation, it is necessary to secure a large area in front of the outer door 1 as an installation space and an operating space for the returning lever 32. I have to. Further, since the turning direction of the return lever 32 is set on the assumption of a right-handed person, there is a drawback that it is difficult for a left-handed person to operate.

An object of the present invention is to provide a coin returning device for a vending machine which requires a very small area on the front surface of the outer door required for installing the coin returning device and which can be easily returned regardless of right handedness or left handedness. To do.

[0006]

In order to achieve the above object, according to the present invention, a coin temporarily held in a coin mech by an operation on the front surface of the outer door is provided on the front surface of the outer door. In a coin returning device of a vending machine for sending to a return opening, a coin returning push button is provided on the front surface of the outer door, and as a first means, a substantially L-shaped bent portion is pivotally supported so as to be rotatable. At the same time, the end of one leg comes into contact with the machine-side end of the coin-return push button, and the other end comes into contact with the coin-return rejector that vertically slides on the upper surface of the coin mech. A transmission lever is provided, and a spring for urging the push button in the direction of pushing back the push button is provided. As a second means, a guide pin protruding to the left and right is provided at the rear end of the push button, and a spring for urging the push button in the direction to push back the push button is provided. The lower end surface is located above the rejector of the coin mech when completed, and the left and right side plates are provided with a slide transmission body having a guide groove that runs backward obliquely upward and on which the guide pin slides.

[0007]

The return operation is of the push button type, so that it suffices that there is only a small installation space for the push button on the front surface of the outer door 1, and the push operation can be easily performed regardless of right-handed or left-handed.

[0008]

1 and 2 show an embodiment of the first means of the present invention, in which parts common or identical to those in FIG. 6 are designated by the same reference numerals. 1 and 2, the coin returning device 3 includes a coin returning push button 4 on the front surface of the outer door 1. The push button 4 is supported by a guide 42 formed integrally with the decorative frame 41 and screwed to the outer door 1. Guide 42
A spring 43 provided between the spring and the spring urges the push-back direction, and the split pin 44 regulates the push-back position. Reference numeral 5 is a transmission lever formed in a substantially L shape, and is a mounting member of the outer door 1 which is rotatable by a support shaft 53 through a bearing 51a formed by bending both edges of one leg 51 at a position near the bent portion. Supported by 13. The upper end of the leg 51 abuts on the inboard end of the push button 4, and the tip of the other leg 52 abuts or approaches the upper surface of the rejector 21 of the coin mech 2. Reference numeral 54 is a spring that is provided between the leg 51 and the mounting member 13 and biases the transmission lever 5 in the direction of arrow A.

In the above-mentioned structure, only a space for installing the push button 5 is required on the front surface of the outer door 1, and a very small space is sufficient as compared with the conventional one. When the coin is returned, the push button 4 is pushed so that the transmission lever 5 rotates in the direction opposite to the arrow A and pushes the rejector 21.
By the operation of the rejector 21, coins of a predetermined amount are sent from the coin mech 2 to the coin return port, and the customer can receive a refund of the coins. Since the above-mentioned return operation is performed only by pushing the push button 4 with a finger, it can be easily operated without distinction between a right-handed person and a left-handed person. When the customer releases his / her finger from the push button 4, the push button 4 and the transmission lever 5 move to the spring 43 and the spring 54, respectively.
