The fine adjustment mechanism 240 is provided in association with the opening circle 168. That is, the guide member 241 made of plastic is attached to the opening circle 168.
The gear member 242 faces 41. On the outer periphery of the gear member 242, a gear portion 242a that meshes with the gear portion 182 of the winding member 181 and a meshing surface portion 242b having a radial uneven portion facing the center are formed on the front surface. A metal adjustment member 242d is embedded in the boss portion 242c (see FIG. 11) facing the opening circle 168. The adjusting member 242d is rotated by a screwdriver. In addition, a rotation smoothing member 243 is inserted into the boss portion 242c to reduce the rotational friction between the gear member 242 and the mounting board 161. The adjustment link member 244 faces the gear member 242. Adjustment link member 244
Has a meshing surface portion 244a that engages with the meshing surface portion 242b on the rear surface. Also, the adjusting link member 244
A hexagonal engagement square tube portion 245 is integrally projectingly provided on the front surface of the, and a pressing spring 247 is abutted so as to be inserted into the engagement square tube portion 245. Further, the adjusting link member 244
An engagement protrusion 246 protrudes from the outer periphery of.

The other end of the holding spring 247 is in contact with the fixing member 249 via the contact ring spring 248. The fixing member 249 has its mounting portions 250a and 250b fixed to the mounting substrate 161 with screws. Therefore, the gear member 242, the adjusting link member 244, the pressing spring 247, and the contact ring spring 248 are all fixed members 249. It is in a state of being stored inside. The fixing member 249 has a cylindrical member formed in a stepped shape, and a first engaging groove 251 and a second engaging groove 252 that engage with the engaging protrusion 246 are connected to the stepped portion. It is formed. The first engagement groove 251 is formed long on the horizontal surface of the step portion, and the second engagement groove 252 is formed short on the vertical surface of the step portion. The gear member 242 is connected to the winding member 18 through a notch 249 a formed on the rear end face side of the fixing member 249.
It is adapted to mesh with the first gear portion 182.

A transmission link member 255 is inserted into a connection hole 253 formed on the front end surface of the fixing member 249. At the rear end of the transmission link member 255, an engagement boss portion 255a that engages with the engagement square tube portion 245 protrudes, and at the front end thereof, an interlocking transmission member 75 of the hitting and firing operation device 20 side. Engaging piece 256 that enters and engages with the
Are formed. Then, the transmission link member 255 is
The gear 242 is screwed to the adjusting member 242d of the gear member 242 by a stop washer 257 and a fixing screw 258.
A loosening prevention spring 254 is interposed between the adjustment link member 244 and the stop washer 257.

The fine adjustment mechanism 240 constructed as described above
As shown in FIG. 11, the gear member 242, the adjustment link member 244, and the transmission link member 255 are attached to the boss portion 24.
2c and the engaging boss portion 255a are integrally rotatable about a spindle. Therefore, the transmission link member 25
When 5 rotates by the operation of the hit ball firing operation device 20 side,
By rotating the gear member 242, the rotation is transmitted to the winding member 181, and the strength of the urging force of the coil spring 180 can be adjusted. However, the rotatable range is the first engagement groove 251 where the engagement protrusion 246 can move.
Range. In a normal state, the gear member 2
42 and the adjusting link member 244 are connected to the coil spring 18.
With the urging force of 0, the engagement protrusion 246 is always in contact with the left end (the left end when viewed from the front in FIG. 10) of the first engagement groove 251. By the way, in order to adjust the urging force of the coil spring 180 in the initial state, first, the mounting substrate 16
1 Adjusting member 2 from the rear side with a flat-blade screwdriver
Press 42d. Then, the gear member 242 and the adjustment link member 244 are pressed forward against the urging force of the pressing spring 247. At this time, the engagement protrusion 246 is
52. Then, when the driver is rotated in this state, the adjustment link member 24
Since the rotation of the gear 4 is restricted by the second engagement groove 252, only the gear member 242 is rotated, and the meshing positions of the mutual meshing surface portions 242b and 244a are forcibly changed. At this time, the winding member 181 also rotates following the rotation of the gear member 242, and changes its position. When the desired setting is completed, the pressing by the driver is stopped and the gear member 242 and the adjustment link member 244 are urged again by the pressing spring 247 to return to the original position, whereby the position of the winding member 181 in the initial state is returned. Therefore, the adjustment of the biasing force of the coil spring 180 in the initial state can be finished.

As described above, the hitting ball launching device 160 of the embodiment is integrated on the mounting substrate 161, and the integrated mounting substrate 161 is mounted at a predetermined position from behind the front frame 1. The hit ball launching device 160 can be attached to the pachinko game machine with only a simple operation. Of the above-mentioned mechanisms, the urging mechanism 170 and the fine adjustment mechanism 240 have the operation amount of the operation mechanism 100 transmitted via the transmission mechanism 98 and the ball striking rod, as is clear from the description. A hitting force adjusting mechanism for adjusting the elastic force of 201 is configured.

Hitting Ball Launching Drive Circuit Next, a driving circuit for driving the above-mentioned hitting ball launching device 160 will be described with reference to FIGS. 13 and 14. In this embodiment, the hitting motor 222 is not directly supplied with AC power, but is supplied with power via a touch detection circuit 280 as shown in FIG. The touch detection circuit 280 is for determining whether or not the player is actually playing a game by touching the operation handle, and after adjusting the operation handle, fixing the operation handle with a matchstick or the like, When the player moves away from the gaming machine, the driving of the ball hitting motor 222 is prohibited. In FIG. 13, reference numeral 93 denotes a motor switch that is turned on and off by an operation handle (the rotation operation member 114 of the hit ball firing operation device 20), and 47 is switched by the single push button 43 provided near the operation handle. This is a single-shot switch. Reference numeral 292 is a capacitor for generating a current phase difference.

Next, the configuration and operation of the touch detection circuit 280 will be described with reference to FIG. The touch detection circuit 280 includes an oscillation circuit 281 and a flip-flop 282.
, A transistor circuit 283, and an electromagnetic relay 284. The tentacle detection member 133 is provided so that a player's hand touches the operation handle, and the tentacle detection member 133 includes a flip-flop 282.
Is connected to the input side of. The operation of the touch detection circuit 280 is as follows.

The output voltage of the oscillation circuit 281 is E0, the input voltage to the set terminal S of the flip-flop 282 is VS,
Let us consider the state of each voltage with the input voltage VR to the reset terminal R and the output voltage of the flip-flop 282 as V0. First, the variable resistor 285 is adjusted so that VS> VR. That is, the resistance value RS of the variable resistor 285 is set to be larger than the resistance value RR of the series connection of the resistors 286 and 287.

Here, the NOR gates 288S and 288R forming the flip-flop 282 are, for example, C-MO.
S, and when viewed from the input side of the flip-flop 282, they have capacitances CS and C, respectively.
It can be regarded as R. Therefore, now, the oscillation circuit 28
When the voltage constants from 1 to E0 are applied to the flip-flop 282, τS = RS CS τR = RR CR, where τS and τR are the time constants for charging the capacitance. Here, if CS = CR, then .tau.S> .tau.R (RS> RR). Therefore, considering the time constant, E0, VS, VR
FIG. 14A shows the relationship of FIG. More specifically, when the voltage E0 is applied from the oscillation circuit 281, the reset terminal R of the flip-flop 282 goes high. Subsequently, the set terminal S becomes high level after a delay of a predetermined time (this delay of the predetermined time is caused by a difference in time constant). 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. 14A, VTH represents the threshold level of the input terminal of flip-flop 282.

Next, the case where the hand touches the tentacle detecting member 133 will be considered. At this time, when viewed from the input side of the flip-flop 282, that is, the output terminal side of the oscillation circuit 281,
It can be considered that a capacitor 289 is connected in parallel to the NOR gate 288R at the connection point between the resistors 286 and 287. Therefore, the time constant τR for charging the NOR gate 288R considered as a capacitor is equal to the value of the capacitor 2
It becomes τ R ′ with a delay of charging 89. At this time, if the value of the capacitor 289 is selected so that .tau.R '>. Tau.S, the fall of the voltage waveform of the reset terminal R is later than the VS as shown by the dotted line in FIG.

FIG. 14B is a timing chart showing changes with time of the output voltage E0 output from the oscillation circuit 281, the set terminal voltage VS of the flip-flop 282, the reset terminal voltage VR and the output terminal voltage V0. Mainly referring to FIG. 14B, when the player's hand does not touch the (a) tentacle detecting member 133, (b) the tentacle detecting member 1
In the case where the player's hand is touching 33, the output voltage level of the flip-flop 282 changes in each case, and the transistor circuit 2
How the 83 operates will now be described.

(A) When the player's hand is not touching the tentacle detecting member 133: When the pulse voltage output from the oscillation circuit 281 changes at a constant interval as shown in (A), the flip-flop 282 is set. The voltage of terminal S is (B)
It changes as shown in. That is, the voltage at the set terminal responds to the rise of the pulse voltage E0 with the time constant τS.
Rises, and exceeds the threshold value VTH at time t2. In this way, when the threshold value VTH is exceeded, the flip-flop 2
The set terminal S of 82 becomes high level. The voltage E
In response to the fall of 0, VS falls with the time constant τS.

Similarly, the voltage of the reset terminal S changes as shown in FIG. The voltage VS of the above-mentioned set terminal
The only difference is that the rise and fall time constants τ R are different. Therefore, the voltage of the reset terminal R becomes high level at the time t1. When the voltage VS at the set terminal S and the voltage VR at the reset terminal R change at the timing as described above, the flip-flop 28
The output V0 of No. 2 changes as shown by (D). That is, the output voltage V0 becomes a pulse voltage having an extremely narrow pulse width that rises at time t1 and falls at time t2. When this pulse voltage is applied to the transistor circuit 283, the voltage is absorbed by the CR circuit 291 provided in parallel with the base of the switching transistor 290,
The switching transistor 290 does not turn on. Therefore, no current flows through the electromagnetic relay 284 and the hitting motor 22
2 is inoperable.

(B) When the player's hand touches the tentacle detecting member 133: In this case, as shown in (B '), the voltage change of the set terminal S causes the tentacle detecting member 133 to touch. This is the same as the case where there is not, but the voltage state of the reset terminal R is different. That is, as shown in (C '), the voltage at the reset terminal R rises with the rise of the pulse voltage E0, but its time constant increases to .tau.R' and rises gently. Therefore, the flip-flop 282
First, the set terminal S becomes high level, and then the reset terminal R becomes high level. If the set terminal S and the reset terminal R change in this order, the output level of the flip-flop 282 changes as shown by (D '). That is, the output voltage of the flip-flop 282 is a pulse voltage having a relatively wide pulse width that rises in response to the fall of the set terminal S and falls in response to the rise of the set terminal S. This pulse voltage cannot be absorbed by the CR circuit 291 of the transistor circuit 283, and a voltage is applied to the base of the switching transistor 290 to turn on the switching transistor 290. Therefore, the electromagnetic relay 284 operates and the hit ball motor 22
2 becomes operational.

Although the embodiment has been described by dividing the hitting ball launching operation device 20, the hitting ball launching device 160, and the hitting ball launching drive circuit into a pachinko gaming machine, the player launches a hitting ball. When the rotating operation member 114 of the operating device 20 is rotated, the hitting motor 222 of the hitting ball launching device 160 starts to rotate based on the hitting ball launching drive circuit. Then, the turning motion of the turning operation member 114 is transmitted to the fine adjustment mechanism 240 side of the hit ball firing device 160 via the transmission mechanism 98 housed in the housing space 54 of the mounting board 21, and the urging force of the coil spring 180 is applied. Is adjusted. The firing speed of the hit ball at the firing position 9 of the hit ball firing rail 8 becomes substantially constant in accordance with the adjusted biasing force of the coil spring 180, and the player can hit the hit ball at a target position.

[0071]

As is apparent from the above description, the present invention fixes the operating mechanism for adjusting the hitting force to the mounting board that also serves as the decoration board, and mounts the mounting board on the front surface of the ball game machine. In a hitting ball launching operation device configured to be attached to a frame, a storage space is formed on the back surface of the mounting board, and further, on the back surface of the mounting board, at least in the vicinity of the fixed portion of the operation mechanism, facing backward in the storage space. Since the rising wall stands upright, the mounting board has a reinforcing structure in the vicinity of the operation mechanism fixing part of the mounting board, and the operation board is fixed even when a large load is applied to the operation mechanism by the player. Does not crack or break.
Further, when a reinforcing member for fixing the operation mechanism is provided from the back surface of the mounting board and the reinforcing member is extended to cover the rear surface of the standing wall, the mounting board, the standing wall, and the reinforcing member provide a reinforcing space. Since it is formed, the structure becomes stronger and the mounting substrate can be protected against a larger load.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hitting ball launching operation device in a ball-playing machine such as a pachinko-gaming machine for playing a game of pachinko balls, and more particularly to a structure of an operation handle portion operated by a player. is there.

[0002]

2. Description of the Related Art Conventionally, as a hitting ball launching operation device for a ball game machine, a rear gripping member is fixed to a front frame, and a front gripping member is fixedly connected in front of the rear gripping member through a connecting pillar. It is known that a rotation operation member is rotatably provided at a position where the rear grip member and the front grip member overlap with each other, and an operation piece protruding outward is formed on a peripheral edge of the rotation operation member. There is. [0003]

In the conventional hitting ball launching operation device described above, the rear gripping member and the front gripping member are connected from the base to the tip by a plurality of connecting columns having the same thickness. However, in a hitting ball launching operation device in which the player's entire weight is sometimes added, if the thickness of the connecting pillar connecting the rear gripping member and the front gripping member is too thin, the connecting pillar It may be broken or cracked and the rotation operation member cannot be operated. On the other hand, the fact that the rotation operating member is sandwiched between the front gripping member and the rear gripping member means that the connecting column needs to pass through the inner surface of the rotation operating member. If it is too thick, the ratio of the occupied area of the slit hole for penetrating the connecting column on the inner surface of the rotary operation member increases, the strength of the rotary operation member itself weakens, and the smooth rotary operation of the rotary operation member is performed. There is a drawback that you can not do. The present invention has been made to solve the above-described inconvenience, and an object of the present invention is to strongly connect a rear grip member and a front grip member, and to improve strength and operation of a rotary operation member. An object is to provide a hitting ball launching operation device for a ball-playing game machine, which can improve the game playability.

[0004]

In order to achieve the above-mentioned object, the present invention is connected to a rear grip member which is attached to the front of the front frame and to the front of the rear grip member via a connecting column. A front gripping member, and a pivoting operation member that is located between the rear gripping member and the front gripping member and that adjusts the firing force of the hit ball. While the base portion is formed thick, an arcuate slit is formed on the inner surface of the rotation operation member, and the distal end portion of the connecting column is penetrated through the slit.

[0005]

According to the present invention, the connecting pillar for connecting the front gripping member and the rear gripping member is formed such that the base portion is thicker than the distal end portion, while the arcuate slit is formed on the inner surface of the turning operation member. Since the slit penetrates the tip of the connecting column, the front gripping member can sufficiently withstand the load applied by the player by the thickness of the base, and the thin portion of the tip rotates. Since the operating member is penetrated, it is not necessary to form the occupied area of the slit so much,
The strength of the turning operation member can be increased, and the turning operation of the turning operation member can be smoothly performed.

A hitting force adjusting mechanism for adjusting the elastic force of 201 is configured.

Hitting Ball Launching Drive Circuit Next, a driving circuit for driving the above-mentioned hitting ball launching device 160 will be described with reference to FIGS. 13 and 14. In this embodiment, the hitting motor 222 is not directly supplied with AC power, but is supplied with power via a touch detection circuit 280 as shown in FIG. The touch detection circuit 280 is for determining whether or not the player is actually playing a game by touching the operation handle, and after adjusting the operation handle, fixing the operation handle with a matchstick or the like, When the player moves away from the gaming machine, the driving of the ball hitting motor 222 is prohibited. In FIG. 13, reference numeral 93 denotes a motor switch that is turned on and off by an operation handle (the rotation operation member 114 of the hit ball firing operation device 20), and 47 is switched by the single push button 43 provided near the operation handle. This is a single-shot switch. Reference numeral 292 is a capacitor for generating a current phase difference.

Next, the configuration and operation of the touch detection circuit 280 will be described with reference to FIG. The touch detection circuit 280 includes an oscillation circuit 281 and a flip-flop 282.
, A transistor circuit 283, and an electromagnetic relay 284. The tentacle detection member 133 is provided so that a player's hand touches the operation handle, and the tentacle detection member 133 includes a flip-flop 282.
Is connected to the input side of. The operation of the touch detection circuit 280 is as follows.

The output voltage of the oscillation circuit 281 is E0, the input voltage to the set terminal S of the flip-flop 282 is VS,
Let us consider the state of each voltage with the input voltage VR to the reset terminal R and the output voltage of the flip-flop 282 as V0. First, the variable resistor 285 is adjusted so that VS> VR. That is, the resistance value RS of the variable resistor 285 is set to be larger than the resistance value RR of the series connection of the resistors 286 and 287.

Here, the NOR gates 288S and 288R forming the flip-flop 282 are, for example, C-MO.
S, and when viewed from the input side of the flip-flop 282, they have capacitances CS and C, respectively.
It can be regarded as R. Therefore, now, the oscillation circuit 28
When the voltage constants from 1 to E0 are applied to the flip-flop 282, τS = RS CS τR = RR CR, where τS and τR are the time constants for charging the capacitance. Here, if CS = CR, then .tau.S> .tau.R (RS> RR). Therefore, considering the time constant, E0, VS, VR
FIG. 14A shows the relationship of FIG. More specifically, when the voltage E0 is applied from the oscillation circuit 281, the reset terminal R of the flip-flop 282 goes high. Subsequently, the set terminal S becomes high level after a delay of a predetermined time (this delay of the predetermined time is caused by a difference in time constant). 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. 14A, VTH represents the threshold level of the input terminal of flip-flop 282.

Next, the case where the hand touches the tentacle detecting member 133 will be considered. At this time, when viewed from the input side of the flip-flop 282, that is, the output terminal side of the oscillation circuit 281,
It can be considered that a capacitor 289 is connected in parallel to the NOR gate 288R at the connection point between the resistors 286 and 287. Therefore, the time constant τR for charging the NOR gate 288R considered as a capacitor is equal to the value of the capacitor 2
It becomes τ R ′ with a delay of charging 89. At this time, if the value of the capacitor 289 is selected so that .tau.R '>. Tau.S, the fall of the voltage waveform of the reset terminal R is later than the VS as shown by the dotted line in FIG.

FIG. 14B is a timing chart showing changes with time of the output voltage E0 output from the oscillation circuit 281, the set terminal voltage VS of the flip-flop 282, the reset terminal voltage VR and the output terminal voltage V0. Mainly referring to FIG. 14B, when the player's hand does not touch the (a) tentacle detecting member 133, (b) the tentacle detecting member 1
In the case where the player's hand is touching 33, the output voltage level of the flip-flop 282 changes in each case, and the transistor circuit 2
How the 83 operates will now be described.

(A) When the player's hand is not touching the tentacle detecting member 133: When the pulse voltage output from the oscillation circuit 281 changes at a constant interval as shown in (A), the flip-flop 282 is set. The voltage of terminal S is (B)
It changes as shown in. That is, the voltage at the set terminal responds to the rise of the pulse voltage E0 with the time constant τS.
Rises, and exceeds the threshold value VTH at time t2. In this way, when the threshold value VTH is exceeded, the flip-flop 2
The set terminal S of 82 becomes high level. The voltage E
In response to the fall of 0, VS falls with the time constant τS.

Similarly, the voltage of the reset terminal S changes as shown in FIG. The voltage VS of the above-mentioned set terminal
The only difference is that the rise and fall time constants τ R are different. Therefore, the voltage of the reset terminal R becomes high level at the time t1. When the voltage VS at the set terminal S and the voltage VR at the reset terminal R change at the timing as described above, the flip-flop 28
The output V0 of No. 2 changes as shown by (D). That is, the output voltage V0 becomes a pulse voltage having an extremely narrow pulse width that rises at time t1 and falls at time t2. When this pulse voltage is applied to the transistor circuit 283, the voltage is absorbed by the CR circuit 291 provided in parallel with the base of the switching transistor 290,
The switching transistor 290 does not turn on. Therefore, no current flows through the electromagnetic relay 284 and the hitting motor 22
2 is inoperable.

(B) When the player's hand touches the tentacle detecting member 133: In this case, as shown in (B '), the voltage change of the set terminal S causes the tentacle detecting member 133 to touch. This is the same as the case where there is not, but the voltage state of the reset terminal R is different. That is, as shown in (C '), the voltage at the reset terminal R rises with the rise of the pulse voltage E0, but its time constant increases to .tau.R' and rises gently. Therefore, the flip-flop 282
First, the set terminal S becomes high level, and then the reset terminal R becomes high level. If the set terminal S and the reset terminal R change in this order, the output level of the flip-flop 282 changes as shown by (D '). That is, the output voltage of the flip-flop 282 is a pulse voltage having a relatively wide pulse width that rises in response to the fall of the set terminal S and falls in response to the rise of the set terminal S. This pulse voltage cannot be absorbed by the CR circuit 291 of the transistor circuit 283, and a voltage is applied to the base of the switching transistor 290 to turn on the switching transistor 290. Therefore, the electromagnetic relay 284 operates and the hit ball motor 22
2 becomes operational.

Although the embodiment has been described by dividing the hitting ball launching operation device 20, the hitting ball launching device 160, and the hitting ball launching drive circuit into a pachinko gaming machine, the player launches a hitting ball. When the rotating operation member 114 of the operating device 20 is rotated, the hitting motor 222 of the hitting ball launching device 160 starts to rotate based on the hitting ball launching drive circuit. Then, the turning motion of the turning operation member 114 is transmitted to the fine adjustment mechanism 240 side of the hit ball firing device 160 via the transmission mechanism 98 housed in the housing space 54 of the mounting board 21, and the urging force of the coil spring 180 is applied. Is adjusted. The firing speed of the hit ball at the firing position 9 of the hit ball firing rail 8 becomes substantially constant in accordance with the adjusted biasing force of the coil spring 180, and the player can hit the hit ball at a target position.

[0071]

As is apparent from the above description, in the present invention, the connecting pillar for connecting the front gripping member and the rear gripping member is formed such that the base portion is thicker than the distal end portion, while the turning operation is performed. Since an arcuate slit is formed on the inner surface of the member and the tip of the connecting column is pierced through the slit, the thickness of the base can sufficiently withstand the load applied by the player to the front gripping member. In addition, since the thin portion of the tip portion penetrates the rotation operating member, it is not necessary to form the slit occupying area so much, so that the strength of the rotation operating member can be increased, and the rotation operating member can also be rotated. The rotating operation of the operation member can be smoothly performed.
