The semicircular rotation transmission member 39 is fixed to the rear end of the operation rotation shaft 42 by the screw 41 with a washer as described above.
Is formed so that one end of the cable line 83 is locked at one end thereof, and the actuator 91a of the motor switch 91 abuts on the other end. Also, the rotation transmitting member 39
Is fixed by fitting a shaft hole 40 formed in the center of the semicircular shape into a cutout portion 42a of the operation rotation shaft 42, but the shaft hole 40 is operated by cutting the cutout portion 42a. Rotating shaft 4
As a matter of course, it is formed in a shape corresponding to the shape of No. 2, but as described above, the dimension of the shaft hole 40 in the front-rear direction is formed slightly longer than the notch width of the notch 42a. This is because when the rotation transmitting member 39 is fitted into the operation rotation shaft 42 and the screw 41 with washer is screwed into the screw hole, the fastening force of the screw 41 with washer to the rotation transmitting member 39 is strongly applied. is there.

The motor switch 91 provided in connection with the rotation transmitting member 39 functions as a normally open switch, and closes the motor circuit when the rotation transmitting member 39 rotates and the other end and the actuator 91a do not come into contact with each other. The rotation of the hitting motor 162 described later is started. Note that a detailed driving circuit will be described later.

A circular interlocking transmission member 84 is connected to the other end of the cable 83 whose one end is connected to the rotation transmission member 39. The interlocking transmission member 84 is rotatably supported by being fixed to the mounting board 27 with screws.

Are locked in the spring locking holes 86 of the interlocking transmission member 84. For this reason, the interlocking transmission member 84 is always urged to rotate clockwise as viewed from FIG. 3, but a contact projection formed integrally with the interlocking transmission member 84 protrudes from the back surface of the mounting board 27. Abuts on the abutting protruding piece 90 to restrict its clockwise rotation. The interlocking transmission member 84 is formed with a guide groove for guiding the cable line 83 and a locking piece for locking the other end of the cable line 83. A hole 85 is formed. The three engagement holes 85 are formed, and the mounting board 27 and the hitting ball launcher 10 described later are formed.
When the “0” is opposed to the front frame 1, as shown in FIG. 1, the engagement piece 186 of the fine adjustment mechanism 170 provided on the side of the hitting ball firing device 100 is fitted. Thereby, the turning motion of the turning operation member 51 on the hitting ball firing operation device 26 side can be transmitted to the hitting ball firing device 100 side to adjust the elasticity.

The interlocking transmission member 84, the rotation transmission member 39, and the cable 83 constitute a transmission mechanism for transmitting the operation of the operating mechanism 28 to the hitting ball firing device 100, and this transmission mechanism is shown in FIG. So that it is arranged in a storage space 99 formed by the back side of the mounting board 27 and the front frame 1. Note that the storage space 99 communicates with the space formed by the opening 12. The mounting board 27 is provided with positioning projections 89a and 89b at positions corresponding to the positioning holes 14a and 14b of the front frame 1.

When attaching the mounting board 27 constructed as described above to the front frame 1, first, the positioning projections 89a,
89b are fitted into the positioning holes 14a and 14b of the front frame 1 and the fastening screws 36a to 36c are

Then, when the hitting ball firing operation device 26 and the hitting ball firing device 100 are tightened and fixed as described above, the engaging hole 85 and the engaging piece 186 are naturally engaged with each other to fulfill the function of the transmission mechanism. Has become.

Operation Mechanism The operation mechanism 28 includes the rear gripping member 44, the rotary operation member 51, and the middle gripping member 6, which are fixed to the mounting board 27 as described above.
1 and a front gripping member 82. Hereinafter, each of the items will be described separately.

(B) Rear gripping member Next, the rear gripping member 44 will be described with reference to FIGS. The rear gripping member 44 is formed by integrally molding a cylindrical base and a bowl-shaped outer peripheral edge, and the base is fitted at the center thereof with a support column fitted along the outer peripheral shape of the support column 31. The hole 45 is penetrated in the front-back direction. Outside the support column insertion hole 45, a connection line through hole 46 through which a lead wire 50 of an electromagnet 49 described below and a connection line 71 connected to a tentacle detection member 67 described later penetrates is formed. I have.

A mounting groove 47 for accommodating and fixing an electromagnet 49 formed in a semicircular shape is formed on the front surface of the base of the rear gripping member 44. A lead wire 50 is connected to the electromagnet 49, and an electric current is supplied through the lead wire 50 to operate the electromagnet 49, and an iron plate 6 described later is used.
0 is sucked to hold the rotating operation member 51 in that state.

Further, three connecting columns 48a to 48c are protruded inside the outer peripheral edge of the bowl shape. This connecting pillar 4
8a to 48c, the base portion is formed to be slightly thicker than the distal end portion. This is because the distal end portion needs to penetrate the connection column through slits 58a to 58c of the rotating operation member 51. This is because the base portion needs to withstand the load applied by the player via the later-described middle gripping member 61 and the front gripping member 82, and thus it is preferable that the base be formed as thick as possible.

(C) Rotating operation member The rotating operation member 51 has a concave inner peripheral surface 53 having a U-shaped cross section which is open rearward as shown in FIGS. 2 and 2A. As described above, the inner surface 53 of the concave portion has the rear gripping member 4.

Only that portion is wide in the front-back direction, so that the player can easily put his finger. Further, the rotation operation member 51
Is formed at the center of the shaft. Since the shaft insertion hole 55 of the shaft insertion tube portion 54 is adapted to be inserted into the notch 42b of the operation rotation shaft 42, the shape of the operation rotation shaft cut out of the notch 42b. Naturally, it corresponds to the shape of the notch 42, but the length of the shaft insertion hole 55 is set to be substantially the same as the notch width of the notch 42b as shown in FIG. The pivotal operation member 51 is pivotally supported by the relatively long shaft-inserting tube portion 54 because the pivotal operation member 51 is firmly and reliably pivotally supported by the pivotal operation shaft 42. That's why.

On the front side of the rotating operation member 51, concentric outer peripheral protrusions 56 and inner peripheral protrusions 57 are protruded. Connection pillar through slits 58a to 58c through which the connection pillars 48a to 48c penetrate are formed between the outer periphery protrusion 56 and the inner periphery protrusion 57. The connecting column through slits 58a to 58c are arc-shaped long holes, and the turning operation member 51 can turn only within the angular range of the long holes. In addition, the connecting column through slit 58a
Since the holes 58a to 58c are formed at positions sandwiched by the two raised protrusions 56 and 57, their strength is extremely high. Accidents such as destruction or cracking can be prevented.

Further, the inner peripheral protrusion 57 and the shaft fitting insertion tube portion 54
A connection wire penetration slit 59 is formed between the two. Since the connection line penetrating slit 59 is a semicircular long hole, the penetrating connection line 71 is not affected by the turning operation of the turning operation member 51.

2 is provided on the front side of the rotary operation member 51 and on the opposite side of the connection line through slit 59.
As shown in (a), an iron plate 60 is fixed at a position facing the electromagnet 49. Thus, the rotating operation member 5
1 is fixed to the rear gripping member 44, as shown in FIG.
When the electromagnet 49 is energized, the iron plate 60 is attracted, and the turning operation member 51 is fixed at the turning position. The iron plate 60 need not be used as long as it is attracted by the electromagnet 49.

(D) Middle gripping member The middle gripping member 61 is a disc-shaped member,
A relief hole 63 into which the shaft-fitting insertion tube portion 54 is inserted is formed, and a connection line through hole 64 for penetrating the connection line 71 is formed near the relief hole 63. In addition, screw holes 62a to 62c are formed on the rear surface side of the middle gripping member 61, with which the distal ends of the connection columns 48a to 48c abut. Then, a screw is passed through the screw holes 62a to 62c from the front of the middle gripping member 61 to connect the connecting columns 48a to 48c.
The middle gripping member 61 is attached to the rear gripping member 44 by being screwed to 48c.

On the other hand, on the front side of the middle gripping member 61, an engaged portion 6 which engages with an engaging portion 76 of a front gripping member 82 described later.
5 are formed in an appropriate number. Therefore, if the front gripping member 82 having the engaging portion 76 is rotated in a state of being in contact with the middle gripping member 61, the engaging portion 76 and the engaged portion 65 are engaged and the front gripping is performed. The member 82 can be attached to the middle gripping member 61.

A tentacle detecting member 67 is provided on the entire outer periphery of the middle gripping member 61. This tentacle detection member 67

I have. The fastening portions 70a to 70c pass through the screw holes 62a to 62c with the screws, and are connected to the connecting columns 48a to 48c.
c, and is fixed integrally with the middle gripping member 61. At this time,
The connection terminal 72 attached to the end of the connection wire 71 penetrating through the connection wire through hole 64 is simultaneously fixed to one fixing portion 70b with a screw. Thereby, the tentacle detecting member 67
Is sent to a tentacle detection circuit 193 described later via the connection line 71.

Further, a fastening part 66 is formed on the front side of the middle gripping member 61. The fastening portion 66 is formed so as to protrude toward the front gripping member 82, and the fastening hole is directed downward. The description of the fastening portion 66 will be described later in the section of the front gripping member 82.
In the illustrated embodiment, since the tentacle detection member 67 is provided over the entire periphery of the middle gripping member 61, the contact of the player with the operation mechanism 28 is reliably detected.

(E) Front gripping member The front gripping member 82 includes a mounting portion 73 for attaching the front gripping member 82 to the middle gripping member 61, and a gripping portion 74 that can be gripped by a player. And consists of First, the mounting portion 73 will be described.

It can be configured. This drive circuit will be described later in detail.

(I) Fine adjustment mechanism The fine adjustment mechanism 170 is a mechanism for initially setting the urging force of the coil spring 120. The fine adjustment mechanism 170 will be described mainly with reference to FIG. Fine adjustment mechanism 1
70 is provided in relation to the opening circle 107.
That is, a guide member 171 made of plastic is attached to the opening circle 107, and the gear member 172 faces the guide member 171. On the outer periphery of the gear member 172, a gear portion 172a meshing with the gear portion 122 of the winding member 121, and a meshing surface portion 172b having a radially uneven portion facing the center on the front surface are formed. Further, a metal adjustment member 172c is embedded in a boss (not shown) facing the opening circle 107. The adjustment member 172c is rotated by a screwdriver. In addition, a rotation smoothing member 173 is inserted into the boss portion so as to reduce the rotational friction between the gear member 172 and the mounting board 101. The adjustment link member 174 faces the gear member 172.
The adjusting link member 174 is provided on the rear surface thereof with the engagement surface portion 17.
2b. Also,
A hexagonal engaging rectangular tube 175 is integrally provided on the front surface of the adjusting link member 174, and a pressing spring 177 is in contact with the engaging rectangular tube 175 so as to penetrate therethrough. Furthermore,
An engagement projection 176 is provided on the outer periphery of the adjustment link member 174 so as to project therefrom.

The other end of the pressing spring 177 is in contact with the fixing member 179 via the contact ring spring 178. The fixing members 179 have their mounting portions 180a and 180b fixed to the mounting substrate 101 with screws. Therefore, the gear member 172, the adjusting link member 174, the pressing spring 177, and the contact ring spring 178 are all fixed members 179. It is in a state of being stored inside. The fixing member 179 has a cylindrical member formed in a stepped shape, and a first engaging groove 181 and a second engaging groove 182 that engage with the engaging protrusion 176 are connected to the stepped portion. It is formed. First engagement groove 1
Reference numeral 81 denotes a second engagement groove 1 which is formed long on the horizontal surface of the step portion.
82 is formed short on the vertical surface of the step. In addition,
The gear member 172 meshes with the gear portion 122 of the winding member 121 via a notch 179a formed on the rear end face side of the fixing member 179.

A transmission link member 185 is inserted into a connection hole 183 formed in the front end face of the fixing member 179. At the rear end of the transmission link member 185, an engagement boss 185a that engages with the engagement square tube portion 175 is protruded, and at the front end thereof, the interlocking transmission member 84 on the side of the hit ball firing operation device 26 is provided. Engaging piece 186 that enters and engages with the engaging hole 85
Are formed. And the transmission link member 185
It is screwed to the adjusting member 172c of the gear member 172 by a stop washer 187 and a fixing screw 188.
Note that a loosening prevention spring 184 is interposed between the adjustment link member 174 and the stop washer 187.

The fine adjustment mechanism 170 configured as described above
The gear member 172, the adjustment link member 174, and the transmission link member 185 are integrally rotatable about a boss portion and an engagement boss portion 185a as a support shaft. Therefore, when the transmission link member 185 is rotated by the operation of the hit ball firing operation device 26, the gear member 172 is rotated, and the rotating operation is transmitted to the winding member 121, and the strength of the urging force of the coil spring 120 is adjusted. be able to.
However, the rotatable range is the range of the first engagement groove 181 in which the engagement protrusion 176 can move. In a normal state, the gear member 172 and the adjustment link member 174
Are always engaged with the engagement projection 1 by the urging force of the coil spring 120.
76 is in contact with the left end of the first engagement groove 181.

In order to adjust the biasing force of the coil spring 120 in the initial state, first, the mounting board 1
01, the adjusting member 172c is pressed with a flathead screw of a screwdriver. Then, the gear member 172 and the adjustment link member 174 are pressed forward against the urging force of the pressing spring 177. At this time, the engagement protrusion 176 is in a state of engaging with the second engagement groove 182. When the driver rotates in this state, the adjustment link member 1
Since the rotation of 74 is suppressed by the second engagement groove 182, only the gear member 172 is rotated, and the mutual meshing surface portions 172b and 174a are forcibly changed in the meshing position. At this time, the winding member 121 also rotates following the rotation of the gear member 172, and changes its position. When the desired setting is completed, the pressing by the driver is stopped, and the gear member 172 and the adjusting link member 174 are urged again by the pressing spring 177 to return to the original position. Therefore, the adjustment of the urging force in the initial state of the coil spring 120 can be ended.

As described above, since the hitting ball launching apparatus 100 of the embodiment is integrated on the mounting substrate 101, the integrated mounting substrate 101 is mounted at a predetermined position from behind the front frame 1. The hit ball launching device 100 can be attached to the pachinko game machine with only simple operations. Note that among the above-described mechanisms, the urging mechanism 110 and the fine adjustment mechanism 170 are, as apparent from the description,
The amount of operation of the operation mechanism 28 is transmitted via a transmission mechanism, and constitutes a hitting force adjustment mechanism for adjusting the resilience of the hitting rod 141.

(3) Hitting / Launching Driving Circuit Next, a driving circuit for driving the hitting / ballistic launching device 100 will be described with reference to FIGS. 6, 6, 7A and 7B.

In this embodiment, an AC power supply 190 is not directly supplied to the hitting motor 162, but power is supplied via a tentacle detection circuit 193 as shown in FIG. The tentacle detection circuit 193 is for determining whether or not the player is actually playing a game by touching the operation handle 28, and adjusts the operation handle 28 (specifically, the rotation operation member 51). Thereafter, the operation handle 28 is fixed with a match stick or the like, and when the player moves away from the gaming machine, the driving of the ball hitting motor 162 is prohibited.

In FIG. 6, reference numeral 91 denotes a motor switch which is turned on / off by an operation handle (the rotation operation member 51 of the hit ball firing operation mechanism 26), and reference numeral 95 denotes a single-push button 35 provided near the operation handle. It is a one-shot switch that can be switched. 191 is a capacitor for generating a phase difference, and 205 is a tentacle detection circuit 1
It is a drive power supply circuit that supplies power to the 93 flip-flops 195 and the like. The drive power supply circuit 205 is not directly supplied with power from the AC power supply 190, but as shown in FIG.
1 is supplied with electric power.

Therefore, power is not supplied to the tentacle detection circuit 193 in a normal state, and the player turns the motor switch 91 by turning the rotary operation member 51 of the hit ball firing operation mechanism 26. The circuit configuration is such that power is supplied to the drive power supply circuit 205 only once and the tentacle detection circuit 193 becomes operable. For this reason, when the power supply connection line is connected to the connection terminal, no power is supplied to the tentacle detection circuit 193, so that even when an erroneous voltage power supply is inserted, the tentacle detection circuit 193 is not immediately destroyed. Then, it is possible to surely prevent the tentacle detection circuit 193 from being broken by checking whether or not the power supply is a proper voltage power supply before turning on the motor switch 91 which is a drive source switch.

Next, referring to FIG.
The configuration and operation of No. 3 will be described. Tentacle detection circuit 193
Includes an oscillation circuit 194, a flip-flop 195, a transistor circuit 196, and a power supply relay 197.

The operation handle 28 includes the tentacle detection member 67 arranged so that the player's hand can touch the tentacle detection member 67.
Is connected to the input side. The operation of the tentacle detection circuit 193 is as follows.

The output voltage of the oscillation circuit 194 is E 0, the input voltage to the set terminal S of the flip-flop 195 is VS,
Consider the state of each voltage, with the input voltage VR to the reset terminal R and the output voltage of the flip-flop 195 as V0.

First, the value of the variable resistor 198 is set by operating the volume control knob so that VS> VR. That is, the resistance RS of the variable resistor 198 is equal to the resistance R of the series connection of the resistors 199 and 200.
Set to be greater than R.

Here, NOR gates 201S and 201R forming flip-flop 195 are, for example, C-MO
S, and when viewed from the input side of flip-flop 195, they have capacitances CS and Cs, respectively.
Can be caught as R. Therefore, now, the oscillation circuit 19
When the voltages from 4 to E0 are applied to the flip-flop 195, assuming that the time constants for charging the capacitance are τS and τR, respectively, τS = RS CS τR = RR CR. Here, assuming that CS = CR, .tau.S> .tau.R (RS> RR). Therefore, considering the time constant, E0, VS, VR
7A is as shown in FIG.

More specifically, when the voltage E0 is supplied from the oscillation circuit 194, the reset terminal R of the flip-flop 195 goes high. Subsequently, the set terminal S goes high after a predetermined time delay (the delay of the predetermined time is caused by a difference in time constant). Then, when the voltage E0 disappears, the voltage levels of the set terminal S and the reset terminal R fall with a predetermined time constant. In FIG. 7A, VTH represents the threshold level of the input terminal of flip-flop 195.

Next, the case where the hand touches the tentacle detecting member 67 will be considered. At this time, when viewed from the input side of the flip-flop 195, that is, the output terminal side of the oscillation circuit 194,
It can be considered that a capacitor 202 is connected in parallel with the NOR gate 201R at the connection point between the resistors 199 and 200. Therefore, the time constant τR for charging the NOR gate 201R considered as a capacitor is
.Tau.R 'after a delay corresponding to the charging of 02. At this time, if the value of the capacitor 202 is selected so that .tau.R '>. Tau.S, the fall of the voltage waveform of the reset terminal R is later than that of VS as shown by the dotted line in FIG.

FIG. 7B is a timing chart showing changes over time of the output voltage E0 output from the oscillation circuit 194, the set terminal voltage VS of the flip-flop 195, the reset terminal voltage VR, and the output terminal voltage V0. Referring mainly to FIG. 7 (B), a case where the player's hand does not touch (a) the tentacle detecting member 67 and a case where the player's hand touches the (b) tentacle detecting member 67 will be described. The following describes how the output voltage level of the flip-flop 195 changes and how the transistor circuit 196 operates by the change.

(A) When the player's hand is not touching the tentacle detecting member 67: When the pulse voltage output from the oscillation circuit 194 changes at regular intervals as shown in FIG. The voltage at the terminal S changes as shown in FIG. That is, the voltage of the set terminal is
In response to the rise of the pulse voltage E0, the pulse rises with a time constant .tau.s and exceeds the threshold value VTH at time t2. When the threshold value VTH is exceeded, the flip-flop 195
Set terminal S attains a high level. In response to the fall of the voltage E0, VS falls with a time constant .tau.S.

Similarly, the voltage of the reset terminal R changes as shown in FIG. The above-mentioned set terminal voltage VS
The only difference is that the rise and fall time constants .tau.R are different. Therefore, the voltage of the reset terminal R goes high at time t1. When the voltage VS of the set terminal S and the voltage VR of the reset terminal R change at the above timing, the flip-flop 19
5 changes as shown in FIG. That is, the output voltage V0 rises at time t1 and falls at time t2, which is a very narrow pulse voltage. When this pulse voltage is applied to the transistor circuit 196, the voltage is absorbed by the CR circuit 204 provided in parallel with the base of the switching transistor 203,
The switching transistor 203 does not turn on. Therefore, no current flows through the power supply relay 197, and the hitting motor 16
2 is inoperable.

(B) When the player's hand is touching the tentacle detecting member 67: In this case, as shown in (B '), a change in the voltage of the set terminal S is caused by touching the tentacle detecting member 67. This is the same as the case without, but the voltage state of the reset terminal R is different. That is, as shown in (C '), the voltage of the reset terminal R rises with the rise of the pulse voltage E0, but its time constant becomes large as .tau.R', and rises slowly. Therefore, the flip-flop 195 first has its set terminal S at a high level, and then its reset terminal R at a high level. If the set terminal S and the reset terminal R change in such an order, the output level of the flip-flop 195 changes as shown by (D '). That is, the output voltage of the flip-flop 195 rises in response to the fall of the set terminal S,
The pulse voltage has a relatively wide pulse width and falls in response to the rising of the set terminal S. This pulse voltage is
The voltage cannot be absorbed by the CR circuit 204 of the transistor circuit 196, a voltage is applied to the base of the switching transistor 203, and the switching transistor 203 is turned on. Therefore, the power supply relay 197 operates, and the hitting motor 16
2 becomes operational. When the power supply relay 197 is turned on, the operation display lamp 192 is turned on, and the hit ball launching device 10
0 informs that it is operating.

As is clear from the above description, the tentacle detection circuit 193 in the above embodiment is
The hitting motor 162 is driven by detecting that the player has touched the tentacle detecting member 67. In this embodiment, the tentacle detecting circuit 193 further controls the electromagnet 49 as shown in FIG. 8 or FIG. Acts as a condition for activation. First, in FIG. 8, the handle fixing switch 94 and the tentacle detection circuit 1
The output of 93 is input to the AND gate 210, and the output of the AND gate 210 becomes the set signal of the holding circuit 211. The output of the tentacle detection circuit 193 is output from the inverter 2
13 is used as a reset signal for the holding circuit 211. Further, when the holding circuit 211 is set, the driver 212 operates to turn on the electromagnet 49.

In the above-described circuit configuration, the player makes contact with the tentacle detecting member 67 while rotating the rotating operation member 51 included in the operating mechanism 28, and a high-level signal is derived from the tentacle detecting circuit 193. When the handle fixing switch 94 is turned ON in the state where the
The set signal is derived from 0, and the holding circuit 211 is activated. For this reason, the electromagnet 49 is
Is turned on, so that the iron plate 6
0 is attracted by the electromagnet 49, and the rotation operation member 51 is fixed at that position. In addition, as long as the high-level signal is derived from the tentacle detection circuit 193, the inverter 2
13, the low-level signal inverted by the holding circuit 21
Since it is input to 1, the holding circuit 211 is not reset. Therefore, the player operates the rotation operation member 51.
Without holding against the urging force of the coil spring 120, the rotation operation member 51 is held at a desired position simply by touching the tentacle detection member 67, thereby securing a constant firing force. You can play, and you won't get tired by playing for a long time.

On the other hand, when the player stops touching the tentacle detection member 67 and the signal from the tentacle detection circuit 193 is no longer derived, the signal is inverted from a low level signal to a high level signal by the inverter 213 and input to the holding circuit 211. Therefore, the holding circuit 211 is reset and the electromagnet 49 is turned off. Therefore, as long as the player does not hold the rotation operation member 51, the rotation operation member 51 returns to the initial state before the rotation operation, and the fixed state is released. of course,
At this time, the driving operation of the hit ball motor 162 is also stopped by the circuit configuration of FIG.

In the above circuit configuration, when the output signal from the tentacle detection circuit 193 disappears, the electromagnet 49 is immediately turned off.
As shown in (5), the electromagnet 49 may be turned off after a certain period of time after the output signal from the tentacle detection circuit 193 disappears. That is, in FIG. 9, the reset signal is derived to the holding circuit 211 by the timer 216 instead of the inverter 213 in FIG. 8, and the set signal is input to the timer 216 from the falling differentiation circuit 214. The reset signal is input from the rising differentiating circuit 215.

When the high level is derived from the tentacle detecting circuit 193, the rising differentiating circuit 215 is operated, a reset signal is derived to the timer 216, and the timer 216 is kept in a reset state. When the signal from the tentacle detecting circuit 193 is no longer derived, the falling differentiating circuit 214 operates to set the timer 216, and the holding circuit 211 is reset by a time-up signal after a predetermined time. Therefore, in this case,
The electromagnet 49 is configured to be turned off a fixed time after the output signal from the tentacle detection circuit 193 disappears. In this case, if there is an output signal from the tentacle detection circuit 193 again before the time-up signal is derived from the timer 216 after the output signal from the tentacle detection circuit 193 disappears, the rising differentiation circuit 215 Operates to reset the timer 216, so that the electromagnet 49
The N state is maintained, so that the fixed state of the rotating operation member 51 is maintained.

As described above, in any of the circuit configurations shown in FIGS. 8 and 9, the handle fixing switch is provided under the condition that the player comes into contact with the tentacle detection member 67 and the output signal is derived from the tentacle detection circuit 193. When the 94 is pressed, the electromagnet 49 is actuated to fix the turning operation member 51, so that the player does not need to hold the turning operation member 51 against the urging force of the coil spring 120. By simply touching the tentacle detecting member 67, the turning operation member 51 is held at a desired position, whereby a constant firing force can be secured, and the player does not get tired even after a long game. In addition, since the output signal from the tentacle detection circuit 193 is not derived by stopping the player from touching the tentacle detection member 67, the holding circuit 211 that holds the operation of the electromagnet 49 is reset, and thereby, the rotation operation member The fixed state of 51 is released.

Incidentally, in the above embodiment,
Although the rotation operation member 51 is fixed by the electromagnet 49, the rotation operation member 51 may be fixed by a configuration other than the electromagnet 49. For example, the structure shown in FIGS. 10 to 13 may be adopted. To explain this,
First, in FIG. 10, a sector gear 224 is fixed to a rear end of a rotation shaft 223 of an operation handle 221 having a finger hook 222 formed on an outer periphery. Lock teeth 225 are formed on the outer periphery of the sector gear 224, and one end of a cable 226 is connected to the upper end thereof. The other end of the cord 226 is
It is connected to one end of a long urging spring 228 via a pulley 227. The other end of the biasing spring 228 is
9 is urged so that a hammer spring 230 formed at the tip of the hitting rod 229 faces the firing position of the firing rail device 241. A rotating roller 2 is provided at the tip of a lever 231 fixed coaxially with the hitting rod 229.
31a is provided rotatably, and this rotating roller 231a
The driving blade 233 of the hitting motor 232 can be freely engaged and disengaged. That is, when the hitting motor 232 rotates, the driving blade 233 and the rotating roller 231a intermittently engage, and the hitting rod 229 is reciprocally rotated against the urging force of the urging spring 228. By rotating the operation handle 221, the urging force of the urging spring 228 can be changed to adjust the firing force of the hit ball.

In such a launching apparatus, the locking teeth 225 of the sector gear 224 have the handle fixing mechanism 220
Are provided to engage. Handle fixing mechanism 220
A solenoid 238 connected via a connecting shaft 237 at the upper end of the locking and fixing lever 234 having locking teeth 235 meshing with the locking teeth 225.
It is composed of The locking and fixing lever 234 is pivotally supported about a pivot shaft 236 at the lower end thereof, and a plunger 239 of a solenoid 238 is connected to the locking and fixing lever 234 by a connecting shaft 237. In addition, a return spring 240 is provided on the solenoid 238, and the locking teeth 235 are always biased in a direction that does not engage with the locking teeth 225 of the sector gear 224.

Also in the hitting ball launching device configured as described above, the handle fixing switch 94 is operated under the condition that the player comes into contact with the tentacle detecting member 67 and the output signal is derived from the tentacle detecting circuit 193. When the pressing operation is performed, the solenoid 238 is operated and the sector gear 224 is operated.
Is fixed, the player does not need to hold the operation handle 221 against the urging force of the urging spring 228, but simply touches the tentacle detection member 67 to move the operation handle 221 ( By holding the sector gear 224), a constant firing force can be secured, and the player does not get tired even after a long game. Also, by stopping the player from touching the tentacle detection member 67, the tentacle detection circuit 19 is stopped.
Since the output signal from 3 is no longer derived, the holding circuit that holds the operation of the solenoid 238 is reset, whereby the fixed state of the operation handle 221 is released.

Next, in FIG. 11 and FIG.
Is substantially the same as that shown in FIG. 7, but the means for fixing the operation handle 221 is a permanent magnet 24 fixed to a linear stepping motor 242 provided in the operation handle 221.
3 and an iron plate 244 fixed to the operation handle 221. In this case, too, when the handle fixing switch 94 is turned on, the linear stepping motor 242 moves in the direction of the arrow in FIG. 12, so that the iron plate 244 is fixed, and the operation handle 221 is fixed at a predetermined position. When the output signal from the tentacle detection circuit 193 is no longer output, the linear stepping motor 242 rotates in the reverse direction to release the attraction state between the permanent magnet 243 and the iron plate 244, and release the fixed operation handle 221.

Next, FIG. 13 is almost the same as FIGS. 11 and 12, except that the means for fixing the operation handle 221 is fixed to the rear end of the operation handle 221.
The fixed belt 2 is fixed at one end to a fixing portion 247 and at the other end to a linear stepping motor 242.
It differs in that it is configured to be tightened and fixed at 46.
In this case as well, when the handle fixing switch 94 is turned on, the linear stepping motor 242 is
3, the fixing belt 246 tightens and fixes the rotating disk 245, and fixes the operation handle 221 at a predetermined position. Further, since the output signal from the tentacle detection circuit 193 is no longer derived, the linear stepping motor 242 rotates in the reverse direction to release the fastening and fixing of the fixed belt 246 to the rotating plate 245, and the operation handle 22
Release the fixation of 1.

The linear stepping motor 242 shown in FIGS. 12 and 13 has a structure as shown in FIGS. That is, one end of the flat shaft 250 is formed as a cylindrical screw portion 251, and the stopper 252 is fixed at the boundary of the screw portion 251. The shaft 250 is supported at both left and right ends of the casing 253, and a screw receiving portion 254 is formed at a portion corresponding to the screw portion 251. Further, a rotor 255 including a cylindrical permanent magnet 256 formed so as to cover the shaft 250 and iron cores 257a and 257b fixed to front and rear ends of the permanent magnet 256 is provided at the center of the shaft 250. Is supported. Further, since the shaft 250 is slidable in the front-rear direction with respect to the rotor 255,
Each time the shaft 5 rotates, the shaft 250 moves in one of the front and rear directions by the screw portion 251 and the screw receiving portion 254. The iron cores 257a and 257b are provided with a plurality of core teeth protruding from the outer periphery thereof as shown in FIG. 16, but the protruding positions of the front and rear iron cores 257a and 257b are shifted by a half pitch. It is protruding.

A pair of cylindrical stators 258a and 258b corresponding to the iron cores 257a and 257b are fixed to the casing 253 before and after the casing 253, respectively. Stator 25
8a and 258b respectively have a predetermined angle (45 in the figure).
(Degree) The stator teeth 259a to 259h that are directed toward the center at intervals are protruded, and each of the stator teeth 259a to 259h has
The coils 260a and 260b are wound alternately. Thus, by alternately energizing the coils 260a and 260b, the respective stator teeth 259a to 259h become "N".
Pole "or" S pole "
9a to 259h and the pitch between the core teeth of the iron core 257a or 257b causes the rotor 255 to rotate,
Is moved in one direction by the screw part 251 and the screw receiving part 254. Also, by changing the direction of the current flowing through the coils 260a and 260b, the rotor 255
0 moves in the opposite direction.

The structure for fixing the operation handle 221 which is a rotation operation member by a structure other than the electromagnet has been described above with reference to FIGS. 10 to 13, but all the above-described embodiments including the embodiment shown in FIG. In the embodiment, the hitting ball launching device 100 is fixed by fixing the rotation operation member 51 or the operation handle 221 as the firing force adjusting operation means so as not to move. The hitting ball firing device 100 may be fixed by fixing a component that can adjust the firing force. In this case, the component may be provided on either the hitting ball firing operation device 26 side or the hitting ball firing device 100 side, and after fixing, for example, even if the rotating operation member 51 is operated, the firing force is increased. You may comprise so that it may not change. Further, the configurations of the rotation operation member 51 and the operation handle 221 as the firing force adjustment operation means may be different from those of the illustrated embodiment.
In short, any structure can be used as long as the firing force of the hit ball can be adjusted according to the operation amount.

In the above-described embodiment, the firing force fixing means is operated by pressing the handle fixing push button 34. However, a certain period of time (for example, 10 to 20 seconds; time that can be adjusted with a margin to adjust to the desired firing force)
The firing force fixing means may be automatically activated later.

Further, a rotary solenoid, a linear solenoid, or the like may be used instead of the hitting motor 162 as an electric drive source of the hitting ball launching device 100. In this case, the firing force fixing means may be configured to fix the electromagnetic force supplied to the solenoid.

Further, in the above-described embodiment, the tentacle detecting member 67 is provided in the hit ball launching operation device 26, but may be provided separately from the hit ball launching operation device 26. In this case, it is preferable to provide as close as possible. Further, the rotating operation member 51 may be made of a conductive material and may also be used as the tentacle detecting member 67.

Further, a ball detector is provided at the lower end of the ball flow of the hit ball supply tray 4, and the operation of the firing force fixing means is released based on the fact that the ball detector has not detected a ball. May be. In this case, the detection signal from the ball detector may be used as the operating condition of the hit ball firing device and the condition for fixing the firing force. With this configuration, when a game is played in a state where the tentacle detection member is grounded (a state in which the output of the tentacle detection means is derived) and the game is finished as it is, there is no game ball. Nevertheless, it is possible to prevent the hitting ball firing device from continuing to operate and prevent the firing force fixing means from continuing to operate.

Although the entire pachinko game machine including various mechanisms provided on the front frame 1 has been described above, according to the present embodiment, the surplus ball saucer mounting plate 18 is provided so as to project perpendicularly to the lower side thereof. Since the receiving shelf 22 is formed integrally with the mounting plate 18, the rigidity of the surplus sphere receiving plate mounting plate 18 itself can be increased. For example, in the fastening screw insertion holes 19 a to 19 c formed in the mounting plate 18. Even if a crack is generated due to an extremely large stress, when the lower extension of the crack reaches the receiving shelf 22, it does not extend any further.
The surplus ball saucer mounting plate 18 can be prevented from being damaged.
In particular, when the receiving shelf 22 is protruded so as to be in contact with the lower portion of the surplus ball receiving tray 23, the receiving rack 22 receives the vertical load applied to the surplus ball receiving tray 23 and receives the above-mentioned fastening screw insertion holes 19a to 19c. The stress itself generated in the portion can be extremely reduced, and the occurrence of cracks can be suppressed.

[0091]

As is apparent from the above description, in the ball game machine according to the present invention, a receiving shelf projecting perpendicularly to the lower side of the surplus ball tray mounting plate is formed integrally with the mounting plate. Because it was formed, the rigidity of the surplus ball saucer mounting plate itself can be increased,
For example, even if an extremely large stress acts on the fastening screw insertion hole formed in the mounting plate and a crack is generated, when the lower extension of the crack reaches the receiving shelf, it does not extend any more, so that the extra ball Damage to the pan attachment plate can be prevented. Further, in particular, when the receiving shelf is protruded so as to contact the lower part of the surplus ball receiving tray, the vertical load applied to the surplus ball receiving tray is received, and the stress itself generated in the fastening screw insertion hole portion described above is received. Can be made extremely small, and generation of cracks can be suppressed.
