[Detailed Description of the Invention] [Industrial Field of Application] The present invention involves playing one game with a specified number of balls, and when the specified game conditions are met, a specified number of prize balls are ejected into a ball tray. This invention relates to an automatic supply device for a specified number of balls in a pachinko-type combination game machine.

[Prior Art] The present applicant provided an inclined passageway that communicates with a ball receiving tray placed on the front side of a game machine body and reaches in front of the firing position, and struck 46 balls into the inclined passageway by driving a solenoid. In Japanese Patent Application No. 5714572θ, we proposed an automatic supply device for a specified number of balls, which feeds balls one by one to a firing position and counts the number of balls sent out.

[Problems to be Solved by the Invention] However, in this device, the detection of the hit balls lined up in the inclined path and the click 1- of the hit balls sent to the firing position are performed by separate switches. Therefore, not only is the structure complicated and the entire device large, but also the cost is high.

[Means for Solving the Problems] The feature of the automatic supply device for a specified number of balls in the pachinko-type combination game machine according to the present invention is that a ball detection sensor is provided at the bottom of the inclined passage corresponding to the supply port.

The ball detecting sensor is configured to detect the presence or absence of a hit ball in the inclined passage, and to count the operation of sending the ball to the shooting position by the feeding mechanism and the number of balls sent to the shooting position. .

3. A ball-striking handle 12 and a start switch button 13 are provided, and the tip of a ball-striking rod 14 fixed to the shaft of the ball-striking handle 12 faces the firing position W4. In the game section surrounded by the guide 1 knob 6 of the game board 3, a predetermined number of 46 rows of passing checkers 15 are arranged at the bottom, and a display section 16 corresponding to each passing checker 15 is arranged in the center part. Ru. Said each passing chutka 15

The switches 17 are connected to display lamps (not shown) of each display section 16, and are connected to the electronic control section 18.
When the signal from the switch 17 establishes a combination preset by the electronic control unit 18, a score corresponding to the combination is assigned and stored in the memory circuit, and the score is The score is digitally displayed on the score display 19 on the game board 3. 20 is a firing ball detection switch 33 attached to the game board 3'' located above the firing rail 5;
The ball that is being hit backwards on the guide rail 6 is placed in the lower ball receiving tray 11.
A return ball detection switch 34 is provided in the foul ball passage leading to the ball.

On the other hand, there is a ball tank 21 above the back surface of the game board 3, and the prize balls in the ball tank 21 are sent to a prize ball discharge device 23 via a tank rail 22. The prize ball discharging device 23 includes a swingable case body 24 that accommodates a predetermined number of prize balls;
It consists of a solenoid 25 pivotally connected to the case body 24, and when the star 1 to switch buttons 13 are pressed after one game, the score display 19 is activated by a signal from the electronic control section 18.
The solenoid 25 is activated a number of times corresponding to the number of points displayed.
is driven to discharge a predetermined number of prize balls to the upper ball receiving tray 10 via the prize ball discharge gutter 26.

Reference numeral 27 designates a box-shaped mounting plate for the device of the present invention located on the inner surface of the front plate 7 and attached to the front part of the launch rail 5, and has an inlet port communicating with the opening 9. 28
A downwardly inclined inclined passage 1829 is formed through which the balls flow down in a line, and a supply port 30 corresponding to the firing position 4 of the firing rail 5 is provided at the end of the inclined passage 29. A ball detection sensor 32 is installed opposite to the bottom surface 31 at a side position of the supply port 30 at the end of the inclined passage 29. Furthermore, a feeding mechanism is provided at the end of the inclined passage 29 to feed the balls from the supply port 30 to the firing position 4. The feeding mechanism includes a ball feeding solenoid 35 fixed to the mounting plate 27 at a position below the inclined passage 19, and a ball feeding solenoid 35 fixed to the mounting plate 27 near the supply port 30.
a lever piece 37 whose upper end is swingably supported by a shaft 36;
It consists of Ball feed solenoid 35 is plunger 3
The tip of the plunger 8 is made to face the bottom surface 31 of the inclined passage 29 from the side, and under normal conditions, the tip does not protrude into the inclined passage 29 by a spring 39 wound around the plunger 38 as shown by the solid line in FIG. In the normal state, the lever piece 37 has a lower end protrusion 40 facing the side of the supply port 30 as shown by the solid line in FIG.
is biased by a spring 41 so as to close and prevent the ball from being sent out.

The ball detection sensor 32 is, for example, a high frequency oscillation type proximity switch, and is composed of an oscillation circuit, a Schmitt circuit, and an amplifier circuit. An oscillation coil is used as a detection element, and when the ball is placed on the bottom surface 31''2 of the inclined passageway 29, the oscillation energy is absorbed by the ball due to electromagnetic induction phenomenon, causing a change in the voltage of the oscillation circuit, resulting in this novel change. Amplify and send out the output. The output signal is then sent to the ball feed solenoid 35 and the counter circuit via the electronic control section 18.

The ball detection sensor 32 may be a magnetic proximity switch or the like.

The balls put into the ball receiving tray 10 enter the inlet 28 from the opening 9 and flow down the inclined passage 29 in a single line, and are prevented from being sent to the supply port 3o by the lever piece 37 as shown by the solid line in FIG. line up in a continuous state. The ball B riding on the bottom surface 31 of the inclined passage 29 is detected by the ball detection sensor 32, and the ball feeding solenoid 35 is energized by the detection signal. As the ball feed solenoid 35 is energized, its plunger 38 projects into the inclined passage 29 against the bias of the spring 39, and pushes the ball B with its tip as shown by the chain line in FIG. It is sent out from the supply port 30 to the firing position 4 while being rotated against the bias of. As a result of this sending out of the balls B, there are no more balls on the bottom surface 31 of the inclined passage 29, and at the same time the electric signal of the ball detection sensor 32 changes, and by detecting this change, the number of balls sent out is counted.

That is, this electric signal is sent to the counter circuit, and '1
One by one is subtracted from the set numerical value (for example, 16) of the specified number of one game. When the plunger 38 retreats as the ball feed solenoid 35 is demagnetized and the next ball B1 rides on the bottom surface 31 of the inclined passage 29, it is detected again by the ball detection sensor 32 and is sent to the firing position 4 in the same manner as described above. This device sends out the balls and counts the number of balls, and by repeating the above operations, the balls are sent out sequentially to the firing position 4, and at the same time, the number of man-hours for sending out the balls is counted. Then, when the set value of the counter circuit becomes zero, the drive circuit for the ball feed solenoid 35 is opened by a signal from the electronic control section 18, and ball sending to the supply 1] 30 is stopped.

[Effects of the Invention] As is clear from the above description, according to the present invention, the balls in the ball receiving tray are continuously flowed down to the supply port corresponding to the firing position through the inclined passage, and the ball detection device is installed on the bottom of the inclined passage. A sensor is provided, and the ball detection sensor detects the presence or absence of a hit 1ξ to send the ball to the firing position and calculate the number of man-hours for the ball to be sent out. Compared to the previous model, which required two sensors, the structure is simpler and more compact, and the cost can be reduced.
