FIGS. 7, 8 and 9 show a glass door locking device 70.
It is a figure for demonstrating the structure of. In particular, FIG. 7 is a side schematic diagram showing a state where the glass door 14 is opened, and FIG. 8 is a side schematic diagram showing the glass door 14 in a closed state.
The figure is an exploded perspective view of a glass door locking device 70 as a glass door locking device.

Referring to FIG. 7 to FIG. 9, a glass door locking device 70
Is held on the fixed edge frame 72 attached to the inner side surface of the front frame 12 and on the inner surface side of the fixed frame edge frame 72, that is, on the glass door 14 side so as to slide vertically with respect to the fixed edge frame 72. The actuating lever 74, the actuating lever 26 mounted so as to project orthogonally to the actuating lever 74 in the longitudinal direction and to project backward, and the glass door
14 includes engaging pieces 76a and 76b fixed to the base 14 (see especially FIG. 9). More specifically, the actuating lever 74 is an elongated plate-like member that extends vertically, and its upper and lower ends are
Engaging hooks 78a and 78b are formed, respectively, and
On the upper side of each engagement hook 78a, 78b, there is a push-out edge 80a inclined upward and forward with respect to the length direction of the operating lever 74.
And 80b are formed. Further, engaging long holes 82a and 82b are formed in the upper portion and the lower portion of the operating lever 74, respectively, which are slightly angled with respect to the length direction of the operating lever 74. Further, the operation lever 26 is attached to a substantially central portion in the length direction of the operation lever 74 in a state of protruding rearward of the operation lever 74. The operating lever 74 is slidably attached to the fixed edge frame 72 fixed to the front frame 12. This installation is done by fixing pin 84a of fixed edge frame 72.
And 84b are engaged with engaging long holes 82a, 82b of the operating lever 74. Further, the fixed edge frame 72 and the operating lever 74 are connected by a return spring 86, and the operating lever 74 is always applied with an upward force on the fixed edge frame 72.

Therefore, in a normal state, in other words, in a state where the operating lever 26 is not operated, the operating lever 74 is in a state of being pulled upward with respect to the fixed edge frame 72 as shown in FIG. Then, when the glass door 14 is closed, the engaging hooks 78a and 78b of the operating lever 74 are engaged with the engaging pieces 76a and 76b provided on the glass door 14, respectively.

Therefore, the glass door 14 is unlocked and is smoothly and surely opened by the action of the pushing edges 80a and 80b. In this manner, when the glass door 14 is unlocked, even if the deceleration motor 40, which will be described later, rotates in the reverse direction and returns to the normal position, the glass door 14 is already in the open state, and thus is re-locked. And the unlocked state is maintained.

FIG. 10 is a perspective view collectively showing both the front frame locking device 50 and the glass door locking device 70 described above in order to show the positional relationship between them.

Next, the front frame locking device 50 and the glass door locking device 70
An unlocking device for operating the will be described.

FIG. 11 is an exploded perspective view of the unlocking device used in the embodiment of the present invention.

With reference to FIG. 11, the unlocking device includes a reduction motor 40 and an unlocking actuating member 28 slid by the reduction motor 40.
The reduction motor 40 is fixed to the inner bottom surface of the outer frame 16 by a motor mounting plate 44. On the other hand, the unlocking actuating member 28 is slidably attached to the inner wall of the outer frame 16 by the fixing pins 30 and 32, the fixing fittings 90 and 91, and the attaching screws 92 and 93. The reduction motor 40 and the unlocking actuating member 28 are connected by a connecting link 38 and a crank 94. More specifically, the connecting pin 96 formed at the lower end of the unlocking operation member 28 is inserted into a small hole formed at one end of the connecting link 38 to prevent the connecting pin 96 from falling off. Also, the link
A crank pin 98 of a crank 94 is inserted into a small hole formed at the other end of 38 to prevent the crank pin 98 from falling off. Further, the crank shaft 102 of the crank 94 is connected to the output shaft 100 of the reduction motor 40. As a result, the rotational movement of the reduction motor 40 is converted into reciprocating movement by the crank 94 and the connecting link 38. Therefore, the unlocking operation member 28 can slide up and down.

A magnet 106 is embedded in the crank arm 104 of the crank 94 on the side facing the reduction motor 40. Further, three Hall ICs 108, 110 and 112 are arranged on the surface of the reduction motor 40 facing the crank arm 104. hole
The ICs 108, 110, and 112 are arranged at positions facing the magnet 106 when the crank 94 is rotated and the crank arm 104 is positioned right next to, right above, and right below. The Hall ICs 108, 110 and 112 are adapted to be able to detect when the crank 94 rotates and the magnet 106 comes to a position facing the Hall ICs.

FIG. 12 is a perspective view showing the internal structure of the reduction motor 40 in order to explain the structure thereof. As shown in FIG. 12, in the reduction motor 40, the rotational force of the motor body 114 is such that the motor gear 116, the driven gears 118 and 120, and the transmission gear 1
It is decelerated by 22 and transmitted to the output shaft 100.

FIG. 13 is a side view showing a stop position of the unlocking device in a normal state, in other words, a state in which the front frame 12 and the glass door 14 are closed. As shown in FIG. 13, in a normal state, the crank arm 104 of the crank 94 is in a horizontal position. In this state, the magnet 106 moves the deceleration motor 40
It is controlled by being detected by the Hall IC 108 provided in the. When the crank 94 is in this state, the unlocking actuating member 28 is in the state shown in FIG. That is, the engagement piece formed by bending the upper end of the unlocking operation member 28.
34 does not engage the operating lever 26 of the glass door locking device 70,
Also, the rotating roller mounted below the unlocking actuating member 28.
36 is positioned in a state in which the engaging hook 22b is not pushed up (a state in which the engaging hook 22b is slightly abutted or separated). The engagement piece 34 may be in contact with the actuating lever 26, and the point is that the engagement variation 34 does not push down the actuating lever 26. Therefore, when the unlocking actuating member 28 is stopped in the state shown in FIG. 13, neither the operating lever 26 nor the engaging hook 22b is operated, and the front frame locking device 50 and the glass door locking device 70 are locked. Will never be unlocked.

Next, when the front frame open signal is given to the deceleration motor 40,
The deceleration motor 40 rotates clockwise in FIG. 14 to bring the crank arm 104 into a vertical state at the top as shown. That is, the reduction motor 40 starts rotating from the state of FIG. 13, and the rotation of the reduction motor 40 is stopped when the magnet 106 in the crank arm 104 and the Hall IC 110 face each other.
The crank arm 104 stops in a vertical position above. Therefore, the unlocking operation member 28 is slid upward by the crank 94 and the connecting link 38 to stop. In this state, the unlocking operation member 28 is in the position shown in FIG. 15 as a whole.

With reference to FIG. 15, when the unlocking actuating member 28 slides upward, the rotating roller 36 that abuts below the engaging hook 22b is
The engaging hook 22 is moved while being pushed up. Therefore, the engagement hook 22b, which is connected to the engagement hook 22 and the engagement hook 22b by the connection plate 66, is disconnected from the stopper pieces 24b and 24a.

Further, the engaging hook 22b has a contact side with the rotating roller 36,
It is angled upward to the rear, approximately 45 ° to the horizontal. Therefore, when the rotation roller 36 pushes up the engagement hook 22b, the engagement hook 22b and the stopper piece 24b are disengaged, and then the rotation roller 36 is pushed up to push the engagement hook 22b forward. Therefore, the front frame 12 to which the engaging hooks 22b are fixed is also pushed forward, and the front frame 12 is automatically and smoothly opened. In this way, when the front frame 12 is unlocked, the reduction motor
Even if 40 is reversed and returned to the normal position, the front frame 12 is already in the open state, so that it is not re-locked and the unlocked state is maintained.

16 and 17 are side views showing the state of the unlocking device when the glass door 14 is opened. In particular, Fig. 16 shows the reduction motor
FIG. 17 is an enlarged view of 40 parts, and FIG. 17 is a side view of the entire unlocking device.

As shown in FIG. 16, when the glass door 14 is opened, the reduction motor 40 rotates counterclockwise in FIG. 16, and the crank arm 104 is in the vertical direction downward. And the magnet 106
And the Hall IC 112 face each other, the deceleration motor 40 stops. Therefore, the unlocking operation member 28 is slid downward. When the unlocking operation member 28 slides downward, as shown in FIG. 17, the engagement piece 34 at the upper end of the unlocking operation member 28 pushes down the operation lever 26. Therefore, as described with reference to FIGS. 7 and 8, the operation of the operating lever 26 unlocks the glass door 14 from the state shown in FIG. 8 to the state shown in FIG. 7, and the glass door 14 is opened. To be done. The deceleration motor 40 constitutes a motor that is activated based on an unlocking signal generated by an unlocking signal generating means described later. The unlocking actuating member 28, the connecting link 38, the crank 94, the actuating lever 26, and the rotating roller 36 impart the driving force of the motor to the front frame locking device or the glass door locking device as the unlocking operating force. The motor driving force applying means is configured. First
FIG. 18 is a rear partial view of the pachinko gaming machine 10 drawn to facilitate understanding of the positional relationship of the unlocking device described above.

Next, a control circuit for controlling the rotation of the reduction motor 40 and controlling the position of the crank 94 (crank arm 104) at each position will be described with reference to FIGS. 13, 14, and 16.

FIG. 19 is a block diagram showing an example of a control circuit of the reduction motor 40. The control operation of the unlocking device will be described mainly with reference to FIG. 13, FIG. 14, FIG. 16 and FIG.

When the opening signal KO of the front frame 12 is given to the pachinko gaming machine 10 (see FIG. 1), the opening signal KO is OR gate.
Flip-flop 126 is set via 124. Then, the set output excites the clockwise motor relay 128,
The deceleration motor 40 rotates to the right. Therefore, the unlocking device
It moves from the state shown in Fig. 13 to the state shown in Fig. 14. When the unlocking device is in the state shown in FIG. 14, the Hall IC 110 derives a high level pulse by detecting the magnet 106. This high-level pulse is given as a reset signal of the flip-flop 126 via the OR gate 130. Therefore, the set output of the flip-flop 126 disappears, and the right-turn motor relay 128
Is demagnetized, and the rotation (right rotation) of the reduction motor 40 is stopped. At the same time, the high level pulse from Hall IC 110
It is applied to the flip-flop 134 via the OR gate 132 to set the flip-flop 134. Therefore, the set output excites the counterclockwise rotation motor relay 136, and the deceleration motor 40 starts left rotation. When the crank arm 104 reaches the horizontal direction shown in FIG. 13 by the left rotation of the deceleration motor 40, the magnet 106 is detected by the Hall IC 108. Therefore, the high level pulse is derived from the Hall IC 108. And the high level pulse is OR gate 13
It is given to the flip-flop 134 via 8 as a reset signal. Therefore, the counterclockwise motor relay 136 is demagnetized, and the rotation of the deceleration motor 40 is stopped. That is, the unlocking device is operated from the normal state shown in FIG. 13 to the front frame 12 shown in FIG.
Then, the operation is stopped by returning to the normal state shown in FIG.

Next, when the opening signal GO of the glass door 14 is given to the pachinko gaming machine 10, the signal GO sets the flip-flop 134 via the OR gate 132. Therefore, the left output motor relay 136 is excited by the set output of the flip-flop 134, and the deceleration motor 40 starts left rotation. Then, when the crank arm 104 reaches the lower vertical position shown in FIG. 16, the Hall IC 112 detects the magnet 106. Therefore, high-level pulse is derived from Hall IC 112,
It is applied to the flip-flop 134 via the OR gate 138 to reset the flip-flop 134. Therefore, the counterclockwise motor relay 136 is demagnetized and the leftward rotation of the deceleration motor 40 is stopped, and at the same time, the high level pulse applied through the OR gate 124 sets the flip-flop 126 and excites the clockwise motor relay 128. To do. Therefore,
The deceleration motor 40 starts rotating to the right. Then, when the crank arm 104 reaches the normal position shown in FIG. 13, the hole I
Flip-flop 12 by high level pulse from C108
6 is reset and the right-turn motor relay 128 is demagnetized. That is, the glass door 14 given to the pachinko gaming machine 10.
The unlock signal from the state shown in Fig. 13 to the
It moves to the state of FIG. 16 to open the glass door 14, and then returns to the normal state of FIG. 13 and stops.

The opening signal of the front frame 12 or the glass door 14 given to the pachinko gaming machine 10 may be configured such that an electric signal is output in response to a normal cylinder lock operation, or Alternatively, an output signal from the key unit or the key as disclosed in the patent application filed by the applicant of the present application on Aug. 27, 1985 may be used. The cylinder lock, the key unit or the key constitutes a predetermined unlocking signal generating means.

FIG. 20 is a configuration block diagram of a control circuit in the case where control of one embodiment of the present invention is performed using a microcomputer. Referring to FIG. 20, a microcomputer 140
Is given a front frame opening signal KO and a glass door opening signal GO. Further, detection pulses from the Hall ICs 108, 110 and 112 are also given. The microcomputer 140 derives an output based on these input signals and controls the rotation of the reduction motor 40 via the interface 142. Further, in this embodiment, the front frame 12 and the glass door are
Each frame opening signal is given to confirm that 14 has been opened surely.

FIG. 21 is a flow chart for explaining the operation of the control circuit shown in FIG.

The control operation by the microcomputer will be described with reference to FIGS. 13, 14, 16, 20, and 21.

In step S1, the microcomputer 140 determines whether or not a pulse of the front frame opening signal KO or the glass door opening signal GO is given, and if either pulse is given, it is given. It is determined whether or not the pulse is the front frame opening pulse KO (step S2).

When the pulse is the front frame opening pulse KO, the first timer in the microcomputer 140 is set (step S
3). The first timer measures, for example, a time T of about 80% of the time required for the deceleration motor 40 to change the crank arm 104 from the state shown in FIG. 13 to the state shown in FIG. As described later, this prevents the crank arm 104 from being rotated excessively and also reduces the speed of the deceleration motor during reverse rotation.
This is to reduce the load on 40.

After the timer is set, the microcomputer 140 rotates the deceleration motor 40 to the right (step S4) and continues until the timer measures a predetermined time T (steps S5 and S4). And
When the timer reaches "T", the microcomputer 140
While gradually braking the deceleration motor 40,
It is determined whether or not there is an output from the IC110 (step S7).
That is, it is determined that the crank arm 104 is in the state shown in FIG. Then, when there is an output pulse from the Hall IC 110, the deceleration motor 40 is rotated in the reverse direction, that is, counterclockwise (step S8). Then, the deceleration motor 40 is rotated until the Hall IC 108 outputs. When there is an output from the Hall IC 108, in other words, when the crank arm 104 returns to the position shown in Fig. 13, it is determined whether or not a frame opening detection switch (not shown) is turned on when the front frame 12 is opened. Yes (step S10). If the front frame 12 is not completely opened, steps S3 to S10 described above are repeated.

When the front frame 12 is opened, the deceleration motor 40 is stopped (step S10), and the control operation ends.

The opening operation of the glass door 14 is also performed in substantially the same manner as the opening operation of the front frame 12, as shown in steps S12 to S19. That is, the timer is set (step S12), the motor is rotated counterclockwise (step S13), and it is determined whether or not the timer has counted "T" (step S14). When it is determined, the brake is applied (step S15). ), Hall IC1
It is determined whether or not there is 12 output (step S16), and if there is, the deceleration motor 40 is rotated to the right (step S17), and the deceleration motor 40 is rotated until there is an output from the central Hall IC 108 (step S18). ), It is determined whether or not the opening detection switch of the glass door 14 is turned on (step S19). The control circuit or microcomputer 140 shown in FIG. 19 constitutes a motor control means for stopping and controlling the motor after the front frame or the glass door is unlocked and the unlocked state is maintained. Has been done.

In the above description of the embodiment, the pachinko gaming machine 10 has been described as an example, but the present invention is not limited to the pachinko gaming machine, and other ball game machines such as coin gaming machines and smart boat gaming machines can be used. It is instructed that the same can be applied to the lock device.

[Effects of the Invention] As described above, according to the present invention, the front frame locking device or the glass door locking device is selectively unlocked by the driving force of the motor and thus unlocked. It becomes unnecessary to perform the unlocking operation by a relatively large manual operation force for locking. Moreover, when the lock device for the front frame or the lock device for the glass door is unlocked, the motor is stopped while the unlocked state is maintained. The inconvenience that the frame and the glass door cannot be opened can be prevented, and power can be saved by stopping the motor.
