In the figure, reference numeral 1 denotes a ball counting machine with a returning function. The ball counting machine with a returning function 1 receives a counter body 2 and a ball 3 which is provided above the counter body 2 and receives a ball 3 temporarily. A hopper 4 that can stay, and a counting unit 5 that is continuously provided below the hopper 4 and that allows the balls 3 to pass through one by one,
The detection unit 6 for detecting each ball 3 passing through the counting unit 5, and the total quantity of the balls 3 passing through the counting unit 5 are calculated and displayed based on the signal of the detection unit 6, and the surplus balls are calculated and displayed and returned. The display unit 7 for instructing, the surplus ball return port 8 located above the counter body 2, and the surplus number of balls 3 are transported to the surplus ball return port 8 based on the return command of the display unit 7 described above. It is composed of a transporting device 9 for driving.

The main body 2 of the counter has a substantially rectangular parallelepiped shape, has an L-shape when viewed from the side, and has a display panel 10 which constitutes a part of the display section 7 at the upper part, and the other part is open. The hopper 4 is attached. A power switch 11 and a power cord (not shown) are attached to the back of the counter body 2, and a chute (not shown) for receiving the counted balls 3 is provided under the power switch 11, and a pipe is provided in this chute. Etc. are connected to transfer the ball 3 to a predetermined place.

The hopper 4 is in the shape of a quadrangular pyramid, the side plates 4a have a gentle slope, the bottom is opened to form a ball discharge port 12, and the received balls 3 are collected in the ball discharge port 12. Let it fall. The capacity of the hopper 4 is set to, for example, a capacity equal to or larger than one capacity, which is the maximum capacity of the balls 3 put out by the customer on the pachinko machine.

The counting unit 5 is provided on the left side in FIG. 3 with a partition plate 13 located at the end of the ball discharge port 12 of the hopper 4 as a boundary. As shown in FIG. 4, the counting unit 5 is formed from a base end (partition plate 13) side to a front end side in a slanted manner to serve as a side wall and a long side wall bar 14 and a bottom wall to serve as a short side wall. The bottom wall bars 15 are alternately arranged, and the side wall bars 14 and 14 and the bottom wall bar 15 successively form the passages 16 through which one ball 3 can pass. The height direction of these passages 16 gradually narrows from the base end side toward the tip end side, and only one ball 3 can pass in the vicinity of the tip end outlet 17. Top plate to guide this
18 is stretched on the top end of the upper surface of the side wall bar 14.

The detection unit 6 is provided with a sensor 19 having a light emitting surface and a light receiving surface located at the tip outlet 17 of each passage 16 of the counting unit 5, and the light emitted from the ball 3 coming out from the tip outlet 17 Every time the light of the sensor 19 is interrupted, it is taken out as a pulse signal and the pulse signal is transmitted to the display unit 7. This detection means is not limited to an optical sensor, but may be another means, for example, a magnetic sensor.

Then, the pulse signals transmitted for each passage 16 are added on the display unit 7, and the number of additions for each passage 16 is added to calculate the total number of balls 3. The total amount of balls 3 after this calculation is immediately displayed on the display panel 10, which is a component of the display unit 7.

When the total number of balls 3 is divided by a fixed number of balls and displayed, if the number cannot be completely divided into a decimal point, the number of balls corresponding to the decimal point is left over. It is displayed as a ball, and the transportation device 9 is instructed to return it.

As shown in FIGS. 5 and 6, the carrying device 9 is provided with a crosspiece 21 for accommodating only one ball 3 on the endless belt 20, and the endless belt 20 is rotated by a driving unit 22 in an inclined state. While counting the balls 3 from the chute (container) 23 that receives a part of the balls 3 that have passed through the counting unit 5 and the detection unit 6 to the surplus ball return port 8 by the metal detection sensor (counting sensor) 24, only the surplus number It is to be transported.

That is, the carrying device 9 is an endless belt.
20 is stretched around pulleys 25 and 26 axially supported at both ends of the frame, and further, of these, a drive unit (drive motor) 22 directly connected to the pulley 26 moves the endless belt 20 on a rail 27. When the endless belt 20 is reversed at the position of 26, the ball 3 housed between the crosspieces 21 and 21 is released, and the metal detection sensor 24 detects a substance that interrupts the magnetic field as a pulse signal, and the pulse signal is displayed on the display unit 7. The number of balls is counted on the display unit 7 in response to this, and when the number of balls as instructed has passed, the display unit 7 issues a stop signal to the drive unit 22,
The rotation of the pulley 26 is immediately stopped.
The surplus balls are discharged to the outside from the surplus ball return port 8 in the upper part of the counter body 2.

Reference numeral 28 in FIG. 1 is a printer for printing out the number of balls.

Next, a ball counting machine 1 with a return function having the above-mentioned configuration
The operating state of will be described. First, the power switch 11 of the ball counting machine with a return function 1 is turned on and other acceptance conditions are confirmed. If there is no problem, the acceptance preparation is completed.
Next, the balls 3 are put into the hopper 4 from a container containing the balls 3 discharged from a game machine such as a pachinko machine. Since the capacity of the hopper 4 is sufficiently larger than the capacity of the ball 3 for one pack in the container, the ball 3 does not overflow from the hopper 4, and the side plate 4a having a gentle slope allows the ball 3 to be located at the center. It gathers at the discharge port 12, falls from this ball discharge port 12 and falls to the counting unit 5. The balls 3 dropped on the counting unit 5 are regulated by the side wall bar 14 and enter each passage 16. At this time, two balls 3 are deeply overlapped on the base end side of each passage 16, but the balls 3 are formed by the inclination of the bottom wall bar 15- and the top plate 18 that gradually narrows the height dimension of the passage 16. Each passage 16 is arranged. The balls 3 arranged in each passage 16 are discharged one by one into the tank from the tip outlet 17. Therefore, the light emitted from the light emitting surface of the optical sensor 19 of the detecting unit 6 is blocked by the balls 3 one by one and does not reach the light receiving surface. The signal is transmitted to the display unit 7.

In the display unit 7, the pulse signals transmitted for each passage 16 are added and the addition numbers of the passages 16 are sequentially added together to calculate the total amount of balls 3, and the result is displayed on the display panel 10. .

The number of balls displayed on the display panel 10 is a fixed number, for example, in the case of a pachinko machine, 3 balls per prize.
When the number is 100, the number of balls displayed on the display panel 10 is 12
If 53, then 1253 will be divided by 100, resulting in 12
There are 53 pieces and surplus balls, which are displayed on the display panel 10. When the button for the surplus ball returning section is turned on, the drive section 22 of the carrier device 9 rotates, the balls 3 on the chute 23 are accommodated between the crosspieces 21 and 21 on the endless belt 20, and the rail 27
Move up and pull the pulley toward the ball return port 8 at the top
At the position of 26, the ball 3 is removed from the endless belt 20, the magnetic field of the metal detection sensor 24 is blocked, this is taken out as a pulse signal, and this pulse signal is transmitted to the display unit 7. The display unit 7 receives the pulse signal and counts the number of balls 3, and as soon as the number of balls becomes 53, a stop signal is transmitted from the display unit 7 to the drive unit 22 and the rotation thereof is stopped.

Therefore, a person can receive the surplus balls from the surplus ball return port 8 on the upper portion of the counter body 2,
Since the ball return port 8 does not project from the front side and is not hit by a person, the ball returning port 8 is on the upper side, so that even a tall person can easily receive the extra balls.
