A rope winding pulley 15 is fixedly attached to the rope winding pulley 15. Therefore, by rotating the operating knob 18 and changing the winding amount of the interlocking rope 13 of the rope winding pulley 15, the spring 10 is expanded and contracted, and the elastic force of the ball hitting rod 7 is adjusted. Reference numeral 19 denotes a finger hook member protruding from the outer peripheral surface of the operating knob 18.

Reference numeral 20 denotes a notch 18 which is cut out from the inside of the outer peripheral surface of the operating knob 18 as shown in FIGS. 3 and 4.

When performing a single-shot action or an automatic continuous firing action, the thumb can be operated easily and fatigue can be reduced.

Next, the electric circuit of the electric pachinko machine configured as described above will be explained.

The micro switch 12 for stopping the motor has a normally closed contact 12a, a normally open contact 12b, and a common contact 12c.
and a normally open contact 12 when the operating piece 2a is pressed.
b and the common contact 12c are connected. The normally closed contact 12a of the micro switch 12 is connected to one end of the power supply, and the common contact 12a is connected to one end of the power supply.
2c is connected to the other end of the power supply via a diode 32, a resistor 33, and a capacitor 34 which are connected in series. A resistor 35 is connected to a connection point a between the normally open contact 12b of the microswitch 12, the resistor 33, and the capacitor 34.

The micro switch 22 for driving the motor installed in the operation knob 18 has a normally closed contact 22a, a normally open contact 22b, and a common contact 22c. The contact point 22c is connected to the contact point 22c. The normally closed contact 22a is connected to the common contact 12c of the micro switch 12,
Further, the normally open contact 22b is connected to one end of the power supply. Further, the common contact 22c is connected via the induction motor M to a connection point b leading to the other end of the power supply.

Next, the operation of the electric pachinko machine configured as described above will be explained.

Now, when the electric pachinko machine shown in FIG. 5 performs an automatic continuous firing operation from a stopped state, first rotate the operating knob 18 to adjust the resilient force of the ball hitting rod 7, and then 24 to press and hold the operation switch 20.

As a result, the common contact 22c of the motor drive microswitch 22 is connected from the normally closed contact 22a to the normally open contact 22b. Then, the induction motor M starts and continues to rotate as long as the operation switch 20 is pressed and held, and the drive cam 2,
The batting rod 7 is automatically and continuously fired via the roller 4 and the like.

At this time, the micro switch 12 for stopping the motor
The common contact 12c repeatedly opens and closes with both contacts 12a and 12b by the operating piece 2a every rotation of the drive cam 2, and when the common contact 12c is connected to the contact 12a, the capacitor 34 is charged. Contact 22a of switch 22 and common contact 22c
Since both are open, the drive of the induction motor M is not affected in any way.

When the operation switch 20 is released, the common contact 22c of the micro switch 22 changes to the normally closed contact 22c.
a, the induction motor M is cut off from power via the normally open contact 22b, but the micro switch 12 for stopping the motor is activated when the rotating operating piece 2a releases the push button of the micro switch 12. When the normally closed contact 12a and the common contact 12c are connected, driving power is supplied through the common contact 12c, the normally closed contact 22a, and the common contact 22c, and the induction motor M rotates. During the firing operation of the batting rod 7, a micro switch 12 for stopping the motor is activated at a relative position corresponding to the firing state.
is pressed by the operating piece 2a of the drive cam 2.
At this time, since the common contact 12c is connected to the normally open contact 12b, the power to the induction motor M is completely cut off, and at the same time, the capacitor 34 is connected to the resistor 35.
→ Normally open contact 12b → Common contact 12c → Normally closed contact 2
2a→Discharge occurs via the common contact 22c, and the induction motor M is DC-braked to immediately stop it. As a result, the batting rod 7 is stopped in a resilient state, and the automatic continuous firing operation is completed.

Next, when the player intermittently performs an arbitrary firing operation, he or she directly presses the operation button 20 with his thumb or the like, and then releases it. As a result, the normally open contact 22b and the common contact 22c of the micro switch 22 for driving the motor are momentarily connected, and power is supplied to the induction motor M for a short time to start the induction motor M. At the same time, the drive cam 2 starts rotating, causing the ball batting rod 7 to spring into action, and as the drive cam 2 rotates, the operating piece 2a releases the pressure on the micro switch 12 for stopping the motor. , the normally closed contact 12a and the common contact 12c are connected, and the common contact 12c→normally closed contact 22a→
Induction motor M via common contact 12c
The induction motor M is maintained in an activated state by supplying power to the induction motor M. At the same time, the capacitor 34 starts charging.

Then, the drive cam 2 is rotated once by the rotation of the induction motor M, and the operating protrusion 2a rotates back to the position corresponding to the elastic state of the ball batting rod 7, pushing the micro switch 12 and closing the normally closed position. Contact 12a
Since the normally open contact 12b and the common contact 12c are connected at the same time as the circuit is opened and the driving power of the induction motor M is cut off, the capacitor 34 is discharged in the same manner as described above, and the induction motor M is DC-braked and stopped immediately. By doing so, it is possible to prevent positional deviation due to inertia of the induction motor M, and to accurately stop the ball hitting rod 7 at a predetermined elastic position.

In particular, since the ball-striking rod 7 is stopped at a predetermined rebound position by applying direct current braking to the induction motor M, the machine can be used even when a player repeatedly makes single-shot movements for each pachinko ball. It can be made extremely durable without causing any physical damage. Furthermore, in this embodiment, since the discharge current determined by the capacitance value of the capacitor 34 is used for braking the induction motor M, an excessive current is not applied to the induction motor M to be braked. There is no flow, and there is no risk of overheating or damage to the induction motor M, especially when the intermittent single action of the batting rod is repeated during a pachinko game.

Therefore, the next springing action of the batting rod 7 is started at the same time as the operation button 20 is pressed, resulting in excellent responsiveness. Further, by applying direct current braking, the induction motor M can be immediately stopped, so that the ball hitting rod 7 can be prevented from shifting in its stopping position and can always be stopped at a constant position.

Note that the present invention is not limited to the embodiment described above, and instead of opening and closing the micro switch 12 through the operation button 20, the operation knob 1
8 may be provided with a push button type switch, or
As shown in FIG. 2, a pressure holding roller 24 is disposed on the corresponding side of the finger hook member 19 to press the operation button 20, but the pressure holding roller 24 is located at the operation knob 18 for the easiest operation. It is also possible to arbitrarily change each member without departing from the spirit of the present invention, such as by conveniently changing the positional relationship of the finger hook member 19, the operation button 20, and the pressure holding roller 24.

As described in detail above, an electric pachinko machine is constructed in such a way that the ball hitting rod is activated by the swinging of the operating arm that swings while sliding on the cam surface of the cam driven by the drive motor. , a normally closed contact, a normally open contact having one end connected to a power source, and a common contact having one end connected to the motor, and when actuated by a player, the normally open contact and the common contact are electrically connected. an operation switch circuit that electrically connects the normally closed contact and the common contact when the operation is released; an operating piece that performs a related operation, a normally open contact, a normally closed contact connected to a power supply at one end, and a common contact connected to the normally closed contact of the operating switch circuit, When the batting rod is in a state other than the elastic state, the normally open contact and the common contact are electrically connected via the operating piece, and when the ball batting rod is not in an elastic state, the normally closed contact and the common contact are disconnected from the operating piece. is electrically connected to a stop switch circuit, and is connected to a normally open contact of the stop switch circuit, and applies electric braking to the drive motor when the player releases the operation and the batting rod is in an elastic state. By providing a braking circuit, it is possible to operate the automatic continuous firing operation of the batting rod and the optional intermittent firing operation of the batting rod with a single operating member, depending on the player's selection. , the electric brake forcibly stops the motor and prevents the motor from shifting due to inertia, so even when players repeatedly make single movements for each pachinko ball, the ball can be hit without mechanical failure. It has the effect of being able to accurately stop the rod at a predetermined rebounding position, having excellent durability, and making the next rebounding action of the batting rod extremely responsive. .
