Only one plate is shown, and 10 is its holding plate.
This holding plate 10 sandwiches each display plate 3 from both sides thereof, and pivotally supports the side end portions near the rotating shafts 2 on both sides, so that each display plate 3 is rotatable. These display boards 3, 3, . . . are arranged in pairs as shown in the figure at the identification information display position to display one piece of identification information. That is, when a picture is used as identification information, for example, the upper half and lower half of the picture are drawn on the front and back sides of each display board 3, and the rotation axis 2 of each display board 3 is drawn.
The image rotates around the rotating shaft 2 and sequentially reaches the upper half display position and the lower half display position, thereby sequentially displaying the upper half and the lower half of the picture. Reference numeral 11 denotes a stopper piece, which engages with the upper end of the display board 3 when the display board 3 is in the upper half display position to prevent it from falling toward the lower half display position. It is something.

The identification information detector 4 has a pattern detection board 12 and a pattern detection sensor 13. The pattern detection board 12 is provided with a detection hole (not shown) corresponding to a special pattern among, for example, 10 types of patterns, and when that special pattern is stopped and displayed, this stop display is Sensor 1 has a detection hole that corresponds to a special pattern.
This sensor 13 is arranged to be detected by 3. That is, the type of picture is detected using the time when the plurality of display boards 3, 3, . . . are at the identification display position.

The motor 6 is equipped with a speed reduction mechanism, and a pinion gear 15 is fixed to its rotational output shaft 14.

The control circuit 7 is composed of an electric circuit, and controls not only the operation and stop of the motor 6, but also the operation and stop of a solenoid device of the display fixing means 9, which will be described later, and a winning device (not shown).

The power transmission means 8 includes gears 16 to 18 and a rotating shaft 1.
9 to 21, transmission plate 22, driven wheel 23, and spring spring 2
It is composed of 4. Gears 16 and 17 are fixed to a rotating shaft 19, and gear 16 is connected to gear 15.
It meshes with. The rotation shaft 20 is disposed coaxially with the rotation shaft 2 of the leaf-type display 1, and the gear 1
8 is fixed to this rotating support shaft 20 and meshes with the gear 17. The transmission plate 22 is also fixed to this rotation support shaft 20, and the power of the motor 6 is transmitted from the rotation output shaft 14, the pinion gear 15 to the gear 16,
Rotating shaft 19, gear 17, gear 18, rotating shaft 2
0 and is transmitted to the transmission plate 22. Rotating shaft 21
is provided between the rotary shaft 20 and the rotary shaft 2 of the leaf-type display 1, which is integral with the rotary shaft 2 and cannot rotate relative to it, and is rotatable relative to the rotary shaft 20 with respect to each other. The driven vehicle 23 is fixed to this rotating shaft 21 and rotates integrally with the rotating shaft 2 of the leaf-type display 1. The resilient spring 24 is interposed between the transmission plate 22 and the driven vehicle 23, and is in elastic contact with both vehicles 22,23. The rotation of the transmission plate 22 is transmitted to the driven wheel 23 by the contact friction of the elastic spring 24, so that the rotation shaft 2 of the leaf-type display 1 rotates in the direction of arrow A.

The display fixing means 9 is composed of a ratchet mechanism consisting of the driven wheel 23 and a lever 25, which constitute a part of the power transmission means 8, and a solenoid device 26. The driven vehicle 23 is configured as a ratchet wheel, and 27, 27, ... are its pawls, and these pawls 27, 27, ... are formed at 10 locations on the circumference of the driven vehicle 23 at equal intervals. has been done. The lever 25 has an intermediate portion rotatably supported by a rotary support shaft 19, and a driven vehicle 2 at one end.
The solenoid device 26 has a pawl 28 that can be engaged with the pawl 27 of No. 3, and the other end is pivotally attached to the tip of a plunger 29 of the solenoid device 26. 30 is a solenoid device 26
This is a solenoid. A ring 31 is fitted to the plunger 29, and a resilient spring 32 is connected to the plunger 29 between the ring 31 and the solenoid 30.
9 is fitted and installed, and this elastic spring 3
2 biases the plunger 29 in the direction of protruding from the solenoid 30. When the solenoid 30 is energized and the plunger 29 is sucked by the solenoid 30, the lever 25 moves in the direction of arrow B.
The claw 27 of the driven vehicle 23 and the claw 28 of the lever 25 are disengaged from each other, and when the solenoid 30 is de-energized, these claws 27 and 28 are engaged.

According to the device 5 configured as described above, for example, when a pachinko ball enters a specific winning hole, the motor 6 is activated, the solenoid device 26 is activated, the engagement between the pawls 27 and 28 is released, and the rotation shaft 2 is rotationally driven, and the leaf-type display 1 displays a variable pattern.

Next, when a variable display stop command is issued by the player's operation or by a timer or the like, first, the operation of the solenoid device 26 is stopped and the pawls 27 and 28 are engaged to prevent rotation of the rotating shaft 2. The rotary shaft 2 is positioned in its rotational direction so that the two display plates 3, 3 are at the upper half display position and the lower half display position, respectively, and the operation of the motor 6 is stopped. Incidentally, even if the rotating shaft 2 is stopped before the motor 6 is stopped in this way, there is no problem because the friction is transmitted by the elastic spring 24.

At this time, when the display stops at a special symbol, the winning device is activated, making it easier for the pachinko balls to win, increasing the winning probability.

(Problems to be Solved by the Invention) However, since it is necessary to position the two display boards 3, 3 relative to the identification information display position, a ratchet mechanism is used, and this ratchet mechanism is used before stopping the motor 6. Since the rotation of the rotating shaft 2 is forcibly stopped by engaging the claws 27 and 28, the rotational angle position of the rotating shaft 2 may be displayed as stopped due to backlash and impact. There is a risk that a picture different from the intended picture may be stopped and displayed, and in this case, the displayed content and the detected content by the identification information detector 4 will be different, resulting in a problem of lack of reliability. There is.

In addition, since the power transmission of the motor 6 is based on frictional conduction using the elastic spring 24, there is a possibility that slipping may occur between the transmission plate 22, the driven wheel 23, and the elastic spring 24, which also reduces reliability. It has the problem of lacking sexiness.

The present invention has been made in view of the problems of the prior art, and an object thereof is to provide a leaf-type display drive device for a pachinko machine that improves reliability. It is in.

(Means for solving problems) Therefore, the present invention has the following configuration.

That is, there is a winning device that operates to increase the probability of winning a prize, and a plurality of display boards that circulate around the rotating shaft by rotating a rotating shaft, and display a plurality of pieces of identification information variably on the plurality of display boards. and an identification information detector that detects the types of the plurality of identification information using the positions of each of the plurality of display boards, and stopping the variable display of the leaf-type display. A pachinko machine that operates the prize winning device based on the detection contents of the identification information detector at the time, the pachinko machine includes a motor, a motor control means for controlling the operation and stop of the motor, and a rotation output shaft of the motor. comprising a power transmission means connected to the rotating shaft to transmit power of the motor to the rotating shaft, and a display fixing means for preventing rotation of the rotating shaft and fixing the display of the leaf-type display; The motor control means includes a stop timing detector that detects the stop timing of the motor in relation to the position of each of the plurality of display boards, and the power transmission means identifies each of the plurality of display boards. An intermittent feed gear is provided that intermittently feeds the rotary shaft so as to sequentially stop at the information display position, and the intermittent feed gear rotates integrally with the original vehicle that continuously receives power from the motor and the rotary shaft. The display fixing means is composed of a master vehicle-side rotary body that rotates integrally with the master vehicle of the intermittent feed gear, and a slave vehicle-side rotary body that rotates integrally with the slave vehicle of the intermittent feed gear. and that the master vehicle-side rotating body is slidable relative to the driven vehicle-side rotating body, and that the subordinate vehicle-side rotating body is not slidable relative to the master vehicle-side rotating body. This is a leaf-type display drive device for pachinko machines.

(Operation of the Invention) According to the present invention, which has such a configuration, if the stop timing of the motor is set so that each display board is positioned at its identification information display position by the stop timing detector, the motor can be stopped. It is also possible to stop the operation of the leaf-type display. In addition, even if inertia is applied when the motor stops, since the rotating shaft is driven by the intermittent feed gear, there is a margin for the interruption in the feed, so the inertia causes the rotation to continue. There is no need for the shaft to rotate excessively and shift the position of the display board. Further, since the driven vehicle-side rotating body cannot slide relative to the original vehicle-side rotating body, after the display board is positioned, it is fixed at that position without play.

On the other hand, since the operation of the leaf-type display can be stopped by stopping the motor, there is no need to stop the rotary shaft of the leaf-type display before stopping the operation of the motor. It is not necessary to provide a degree of freedom in the sense of allowing relative rotation to the leaf display, and the rotation output shaft of the motor and the rotation shaft of the leaf-type display can be strongly connected.

Even if a pachinko ball wins not only in the second special winning hole 57 but also in the third special winning hole 58, 58, the right to make the leaf-type display 70 perform a variable display occurs. In addition, if the picture that is stopped and displayed indicates a miss, the hit detection sensor 79 and the right generation detection sensor 80 are activated.
Nothing is detected, the guide vanes 64, 64 remain closed, and the variable display on the leaf type display 70 is not performed, so nothing happens.

In the right generation state, when a pachinko ball wins in the first special winning hole 45, the guide wings 64, 64 open and the pachinko ball wins in either the second or third special winning hole 57, 58, 58, a leaf type Display device 70
makes a variable display and then stops, and if the picture that is stopped and displayed at this time represents a win, the guide vane 64 operates to indicate a win, while the picture that is stopped and displayed represents the occurrence of a right. If the right has been exercised less than eight times at this point, the right is extinguished, and if the picture that is stopped and displayed indicates a loss, the right has been exercised once. Only the facts remain, and as above, nothing happens.

100 is a motor with a speed reduction mechanism, 101 is a motor control means, 102 is a power transmission means, and 103 is a display fixing means. These motor 100, motor control means 101, power transmission means 102, and display fixing means 103 are leaf type. The motor 100 constitutes a display drive device, and the operation and stop of the motor 100 are controlled by a motor control means 101.
The rotation output shaft 104 of 00 and the rotation shaft 71 of the leaf-type display 70 are connected by a power transmission means 102 so that the power of the motor 100 is transmitted to the rotation shaft 71, and the power of the motor 100 is transmitted to the rotation shaft 71. As a result, rotation of the rotating shaft 71 is prevented, and the display on the leaf-type display 70 is fixed.

The motor control means 101 is composed of a control circuit 84 and a stop timing detector 106. The control circuit 84 includes a timer circuit and a random number oscillation circuit, and has a function of randomly determining the driving time of the motor 100 within a predetermined range based on the outputs of the timer circuit and the random number oscillation circuit. The stop timing detector 106 detects the stop timing of the motor 100 in relation to the position of each display board 72, and its detection signal is input to the control circuit 84, which controls the control circuit 84. Therefore, the motor 100 is de-energized and stopped when the detection signal is output after the drive time has elapsed, and each display board 72
If the stop timing is determined by the stop timing detector 106 so that the symbol is positioned at the picture display position (the upper half display position or the lower half display position), the leaf type display 70 will stop when the motor 100 stops operating. It is now possible to stop the operation.

The power transmission means 102 is composed of rotating shafts 107 and 108, gears 109 and 110, and an intermittent feed gear 111. The rotating shaft 107 is connected to the case portion 50

4, the master wheel 113 is fixed to the rotating shaft 107 and receives the power of the motor 100 continuously, and the follower wheel 114 is fixed to the rotating shaft 108 and is connected to the rotating shaft of the leaf type display 70. 71, and the rotating shaft 71 is intermittently fed by the master wheel 113 and the follower wheel 114 so that each display board 72 sequentially stops at each picture display position. . Here, when the motor 100 is stopped, the inertia force may have an adverse effect on the positioning of each display board 72.
Since there is a margin for the interruption of feeding between the leaf type display 70 and the follower vehicle 114, the rotation shaft 71 of the leaf-type display 70 should be rotated extra due to the above-mentioned inertial force and positioned at the original picture display position. two display boards 72,
This prevents the position of 72 from being shifted and other patterns being displayed.

The original vehicle 113 has six feed levers 115, 11.
5,... at equal intervals in the rotational direction, and the driven vehicle 114 has U-shaped notches 116, 11 at 10 locations around its circumference.
6,... at equal intervals in the rotational direction, and each feed lever 115 has its tip end inserted into each notch 116 by rotation, and the end of each feed lever 115 enters the front end of each notch 116 in the rotational direction. The driven vehicle 114 is rotated by a predetermined angle while engaged with the inner wall of the driven vehicle 114, and then the driven vehicle 114 is disengaged and escapes, and sequentially circulates to the notch 116.
Each display board 72 is fed by a predetermined pitch. The follower vehicle 114 is configured such that when the engagement between the inner wall of the cutout portion 116 and the feed lever 115 of the original vehicle 113 is released, the two display plates 72, 72 stop at the upper half display position and the lower half display position, respectively. The phase is adjusted to

The display fixing means 103 is composed of a rotating body 117 on the original car side and a rotating body 118 on the driven car side. The rotating body 117 on the original car side is fixed to the rotating shaft 107 and rotates integrally with the original car 113 of the intermittent feed gear 111. The driven vehicle side rotating body 118 is fixed to the rotating shaft 108 and rotates together with the driven vehicle 114 of the intermittent feed gear 111. Original vehicle side rotating body 117
is configured such that its circumferential surface is slidable relative to the circumferential surface of the driven vehicle side rotating body 118, and the driven vehicle side rotating body 118
, whose circumferential surface cannot slide with respect to the circumferential surface of the original vehicle side rotating body 117, and these original vehicle side rotating bodies 1
The circumferential surfaces of the rotating body 17 and the driven vehicle side rotating body 118 are engaged with each other, so that after each display board 72 is positioned at the picture display position, it is fixed at that position without play. That is, slide portions 119 are formed at six locations on the circumferential portion of the original vehicle side rotary body 117, and each slide portion 119 has a circular arc surface 120 that is convex with respect to the circumferential surface of the driven vehicle side rotary body 118. have. A cutout portion 121 is formed between the slide portions 119 on the circumferential portion of the original vehicle side rotating body 117. The peripheral part of the driven vehicle side rotating body 118 is composed of ten slidable parts 122, and each slidable part 122 is connected to the sliding part 1.
Concave arc surface 12 that fits the arc surface 120 of No. 19
It has 3. Arc surface 12 of slide portion 119
0 and the circular arc surface 123 of the slidable portion 122 are in sliding contact, and the circular arc surface 120 is in sliding contact with the circular arc surface 123 of the slidable portion 122.
Since it is convex with respect to the arcuate surface 123, it is absolutely possible to slide on the arcuate surface 123, and the arcuate surface 123
Since it forms a concave shape with respect to the circular arc surface 120, it is absolutely impossible to slide on the circular arc surface 120, and only the master wheel 113 of the intermittent feed gear 111 rotates, the slave wheel 114 does not rotate, and the slave wheel side rotates. When the body 118 is not rotating, the arc surface 120 is the arc surface 123.
By sliding the upper part, the original vehicle side rotating body 117
is configured to rotate, and when the slave vehicle 114 is rotated by the master vehicle 113 of the intermittent feed gear 111, the slave vehicle side rotating body 118 rotates together with the slave vehicle 114, and the intermittent feed gear 111 rotates. After the gear 111 stops and the two display plates 72, 72 are positioned, the arc surface 123 becomes the arc surface 120.
Since the driven vehicle-side rotating body 118 cannot be rotated, the rotating shaft 71 of the leaf-type display 70 cannot be rotated, and the two display boards 72, 72 can be moved to their positions without play. This is something that is becoming fixed. Follower vehicle side rotating body 11
8 is designed such that when it is rotated, the apex of the circular arc surface 123 and the circular arc surface 123 enters into the notch 121 of the original vehicle side rotating body 117, and when the slave vehicle side rotating body 118 rotates. , and the original vehicle side rotating body 117 are prevented from interfering with each other. That is, the circular arc surface 12 of the original vehicle side rotating body 117
0 and the arcuate surface 123 of the driven vehicle side rotary body 118 are formed to have the same length, so that they do not protrude from each other at each end when each display board 72 is in its picture display position, and The above-mentioned apex portion is positioned above the notch portion 121 by this rotation.

The stop timing detector 106 of the motor control means 101 is composed of a timing detection plate 124 and a timing detection sensor 125. The timing detection plate 124 is fixed to the rotating shaft 107 and integrated with the original vehicle 113 of the intermittent feed gear 111. It is designed to rotate. This timing detection plate 124
As shown in FIG. 5, six timing detection holes 126, 126, . The timing detection holes 126 are arranged so as to detect each timing detection hole 126 when the timing is reached. This timing detection sensor 12
5 is fixed to a sensor mounting board 127 that is integrated into the case part 50, and the detection signal of this timing detection sensor 125 is input to a control circuit 84. This control circuit 84 determines the presence or absence of this detection signal. It is determined whether or not it is time to stop the motor 100.
Although it is possible to detect the stop timing using a rotary encoder or the like, it is expensive and the configuration of the control circuit 84 becomes complicated. .

(Effects of the Invention) As is clear from what has been described above, the present invention provides the following effects.

Since the stop timing detector detects the stop timing of the motor and stops the motor, the stop timing detector determines the stop timing of the motor so that each display board is positioned at its identification information display position. Ba,
Since the variable display of the leaf-type display can be stopped by stopping the motor, there is no impact when the motor is stopped, and the display board can be accurately positioned.

Since the rotary shaft of the leaf-type display is driven by an intermittent feed gear so that each display board arrives at the identification information display position in sequence, there is a period of time when the display board stops and its feeding is interrupted. Even if inertia is applied when the motor is stopped, the rotation axis of the leaf-type display will not rotate excessively due to the inertia and the position of the display board will not shift.From this point of view, the display board should be Can be positioned accurately.

Since the driven vehicle-side rotating body cannot slide with respect to the original vehicle-side rotating body, after the display board is positioned, it can be fixed at that position without play.

Since the variable display of the leaf-type display can be stopped by stopping the motor, there is no need to stop the rotary shaft of the leaf-type display before stopping the motor operation, so this rotary shaft can be used as the motor's power source. On the other hand, it is not necessary to provide the rotating shaft with a degree of freedom in the sense of allowing relative rotation, and the connection between the rotating output shaft of the motor and the rotating shaft of the leaf-type display can be strengthened. Thus, power transmission is ensured.

The present invention, which has many effects as described above, has extremely high operation reliability in general, and can ensure a comfortable gaming experience without giving players a sense of distrust, making it highly practical.
