[Industrial application fields]
The present invention relates to a ball hitting device for a gaming machine such as a pachinko machine.
[0002]
[Prior art]
In the pachinko machine, as a hitting ball launching device that launches game balls, which are supplied one by one on the firing rail in accordance with the timing of hitting the hit ball from the front supply tray, toward the guide rail of the game board, A launch lever capable of repetitive movement between the start position waiting for the launch and a driving means (e.g., intermittently energizing the launch lever to at least the play position of the game ball with electromagnetic force corresponding to the launch operation) , Rotary solenoids, etc.) are known. Conventionally, a spring member that urges the firing lever to the resilient position, a cam that moves the firing lever to its released position against the urging force of the spring member, and the cam is continuously driven in a certain direction. It is often seen that a motor or the like is provided and the firing lever is biased to the resilient position by bending and releasing the spring member as the cam rotates.
[0003]
[Problems to be solved by the invention]
By the way, in such a conventional example, as a final confirmation at the time of shipment by the manufacturer, adjustment of the hitting point of the launch lever with respect to the game ball on the launch rail, for example, the angle of the tip (tip) facing the bullet position of the launch lever, Or, it is done by adjusting the mounting angle of the whole launch lever, but even at game stores, the hit point of the launch lever changes with time due to the impact of the ball of the game ball, so variation in flight distance and launch direction In order to correct the deviation, it is necessary to periodically adjust the tip angle of the launch lever.
[0004]
In that case, in the conventional type (the spring lever biases the firing lever to the bullet position), the firing lever returns to the bullet position when the motor stops, so a part of the front panel is opened from the front side of the pachinko machine and fired. Easy adjustment of lever tip. However, the electromagnetic type (which biases the launch lever to the bullet position by electromagnetic force) is stopped at the start position where the launch lever waits toward the bullet position, so first move the launch lever to the bullet position. However, since the launch lever is hidden behind the front frame that is out of reach even if a part of the front panel is opened at the starting position, the front lever can be opened and adjusted from the back side. While firing on the front side, you must catch the launch lever instantaneously at the bullet position, and if you release it anyway, it will return to the starting position, so it takes a lot of time for adjustment work There was a problem of requiring labor.
[0005]
The object of the present invention is to effectively solve such problems.
[0006]
[Means for Solving the Problems]
Therefore, resilient positions hammer out the game ball and a possible firing member of the repetitive motion between the start position to wait toward its launch as shown in FIG. 9, the intermittent said firing member to at least the resilient direction by an electromagnetic force game comprising: a firing drive means for biased, a firing operation means for adjusting the electromagnetic force acting on said firing member, and a firing control circuit for controlling the firing drive means based on the operation of the firing operation means in hitting the firing device of the machine, to urge the adjustment request switch that is operated when punch destination adjustment of the firing member is required, the firing member receiving an input of the adjustment request switch the resilient position for a predetermined time There is provided a conversion control means for continuously driving the firing drive means so as to continue, and performing conversion control so that the tip can be adjusted .
[0008]
[Action]
According to this, when it is necessary to adjust the tip of the firing member, if the adjustment request is generated artificially by the adjustment request switch , the firing drive means is configured to continue to bias the firing member to the bullet position for a predetermined time . Is continuously driven so that the tip adjustment is possible , so that it is possible to easily adjust the tip (spot) and the like from the front side during that time . Further, since the launch drive means for launching the game ball is controlled to be converted into a state in which the tip can be adjusted, there is an advantage that only one drive means is required.
[0009]
【Example】
FIG. 1 is a front view of the entire pachinko machine. The front frame 1 has a jackpot indicator lamp 3 above the cover glass 2 of the game board, a pachinko ball supply tray 4 and a tray 5 below the cover glass 2, and a magnetic field. A card reader insertion portion 6 of a card (prepaid card), an operation portion 7 of the ball striking device, and a push button 8 (adjustment request switch) for operation when the tip of the firing lever needs to be adjusted are arranged. .
[0010]
On the cut surface of the outer periphery of the supply tray 4, a card balance indicator 9 that displays the balance frequency (minimum ball lending conversion amount is 1 unit) that the card reader reads from the inserted card, and a ball lending button that promotes the discharge of the lending ball 10, a card return button 11 for instructing the return of the inserted card, and a ball lending effective indicator 12 that is turned on when the lending of the lending ball is valid. The card reader insertion unit 6 is provided with a card confirmation indicator 13 for displaying a normal insertion state of the magnetic card.
[0011]
Then, when the ball lending button 10 is pressed with the magnetic card in the card reader insertion section 6, a predetermined number of lending balls will be described later for each turn-on of the button switch within the card balance range. Through the supply tray 4 or the receiving tray 5. When the card return button 11 is pressed , the inserted card in the card reader is ejected by turning on the button switch so that the magnetic card can be removed from the insertion portion 6.
[0012]
Here, the cover glass 2 of the game board is attached to the front frame 1 through a glass frame 14 so as to be openable and closable, and the front frame 1 is similarly hinged to the machine frame 15. The game board is assembled in the frame of the front frame 1 in an exchangeable manner.
[0013]
A back mechanism board 16 is attached to the back surface of the front frame 1 as shown in FIG. 2, and a discharge processing device 18 that releases pachinko balls from the storage tank 17 as prize balls or rental balls on the back side thereof, and a game board surface. A winning processing device (not shown) that pays out winning balls one by one as a processed ball to the collecting bowl at the rear of the pachinko machine every time the discharging of the winning balls is provided. Further, a hitting ball launching device 20 including a launching lever 19 and a rotary solenoid or the like as a driving means thereof is attached to the lower part of the rear surface of the front frame 1.
[0014]
21 is an accessory control circuit for controlling a command ball discharge command output and a winning ball payout operation in addition to a game board role operation, and 22 is a rental ball discharge command corresponding to a ball lending operation. A card control circuit for subtracting the card balance in the card reader 25 at the end of the discharge, 23 is a discharge control circuit for controlling the discharge process of the pachinko balls based on the winning ball and lending ball discharge commands, and 24 is a ball hitting and will be described later. A launch control circuit that controls conversion drive.
[0015]
As described above, the hitting ball launching device 20 is composed of the operation unit 7 disposed on the front side of the pachinko machine 1, the ball supply mechanism assembled on the back side thereof, the firing lever 19, the rotary solenoid, and the like. 7 includes a fixing knob 27 with a handle 26 on the lower surface of the front frame 1 as shown in FIG. As for the knob 27, the grip part is divided into two in a ring-cut state, and the handle 26 is rotatably held between both parts. The handle 26 is coupled to the rotating shaft in the knob 27 at the center, and forms a deformed finger hook on the outer periphery of the knob 27. A variable resistor (not shown) for adjusting the firing force of the hit ball is attached to the inside of the operation unit 7, and the rotating shaft of the handle 26 is connected to the rotating shaft.
[0016]
When the handle 26 of the fixed knob 27 is turned, the resistance value of the variable resistor changes according to the rotation angle of the handle 26. The variable resistor is connected to the power supply circuit of the rotary solenoid, and adjusts the supply voltage to the rotary solenoid, that is, the hitting force of the hit ball, depending on the turning operation of the handle 26. A touch plate 29 for detecting a grip hand is provided on the surface of the fixed knob 27. Further, a push button 30 (firing stop switch) is added to the side surface of the fixed knob 27 so that the rotary solenoid can be temporarily stopped if necessary even when the handle 26 is held in the operating range. The handle 26 is biased to the initial position by a return spring.
[0017]
Although not shown, the ball supply mechanism is driven by a solenoid, and sends out the game balls from the supply tray 4 on the front surface of the pachinko machine one by one onto the launch rail 31 in accordance with the launch timing of the launch lever 19, and the exposure shown in FIG. It is attached to the back surface of an openable / closable panel (not shown) that covers the part, and the supply tray 4 is arranged on the panel surface.
[0018]
The firing lever 19 is arranged with its distal end (tip) facing the base end of the firing rail 31. As shown in FIGS. 4 and 5, the rotary shaft 37 of the rotary solenoid 36 is provided on one side of the unit substrate 35. It can be attached with nuts. Stoppers 38 and 39 for restricting the rotation stroke of the firing lever 19 are arranged on the unit substrate 35. A stopper 38 for restricting the firing position of the lever 19 is obtained by fitting a square elastic member 41 to the tip of the bracket 40 so that a part thereof protrudes. The screw is fixed at the position, and the position can be adjusted within the range of the long hole 42 when the screw is loosened. The stopper 39 restricts the starting position of the lever 19, and a circular elastic member 43 is mounted on a pin 44 protruding at a predetermined position of the unit substrate 35.
[0019]
The rotary solenoid 36 is fixed to the opposite side of the unit substrate 35 from the firing lever 19. The substrate 35 itself is assembled to the front frame 1 on the back side of the panel 28 of the hitting operation unit 7. The rotary solenoid 36 includes a rotary shaft 37 penetrating the center of the case in the front-rear direction, a link-like rotor (not shown) coupled to an intermediate portion of the rotary shaft 37, and a stator (not shown) surrounding the rotor. ) Etc. By rotating the coil alternately around an even number of iron cores arranged radially at equal intervals on the inner circumference of the case, the rotor also has the same number of permanent magnets corresponding to the iron core as N poles and S on the same circumference. Each is formed by arranging the poles so that they appear alternately.
[0020]
When the direction of current flow to the stator coil is switched via the converter, the magnetic poles of the stator are alternately changed accordingly, so that an attractive force and a repulsive force are applied to each permanent magnet of the rotor. Will be affected. A predetermined phase difference is set in the circumferential direction at the initial position in order to reliably rotate the rotor forward and backward between the stator and the rotor. Further, the stoppers 38 and 39 of the firing lever 19 restrict the rotation angle of the rotor to be smaller than the magnetic pole pitch. Therefore, when the stator is magnetized, the rotor is rotated in the direction in which the phases are overlapped. When the flow direction of the supply current to the stator is alternately switched, the launch lever 19 launches the ball at which the game ball is launched. And reciprocatingly rotate between the starting position waiting for the launch.
[0021]
The flow direction of the supply current to the rotary solenoid 36 is switched at a predetermined timing, and a ball supply mechanism is provided so as to send out the game balls from the supply tray 4 on the front surface of the pachinko machine one by one onto the launch rail 31 at that timing. The firing control circuit 24 (attached to the unit board 35) is driven, and in this example, when the tip of the firing lever 19 needs to be adjusted, when the push button 8 of the front frame 1 is turned on, the firing lever 19 is moved for a predetermined time. A function for controlling the supply current to the rotary solenoid 36 is added so as to stop only at the bullet position.
[0022]
6 and 7 are flowcharts for explaining the operation content of the launch control circuit. The handle 26 for adjusting the striking force is adjusted while the fixing knob 27 of the operation unit 7 is gripped (the touch plate 29 is turned on) on the front side of the pachinko machine. When the launching operation to rotate is performed, on the launching rail 31 via the ball feeding mechanism in accordance with the launching control that switches the supply direction alternately at a predetermined timing with a current value corresponding to the operation angle of the handle 26. The ball feed control is performed to send out the game balls one by one (however, the ball feed is not necessary in a device that mechanically interlocks with the launch lever without relying on the solenoid) (1.09 to 1.11). When the firing operation is canceled, the energization of the rotary solenoid 36 is turned off, so that the firing lever 19 stops at the start position where it waits for launch.
[0023]
When an adjustment request is generated when the push button 8 is turned on, conversion control to an adjustment state in which the firing lever 19 is held in the bullet position is started, and the firing lever 19 is attached in the bullet direction for a predetermined time (for example, 5 seconds). The rotary solenoid 36 is continuously driven with a current in one direction so as to keep on, and the drive of the rotary solenoid 36 is stopped after a predetermined time (1.01 to 1.08). In this case, when the adjustment operation of the launch lever 19 is completed, it is necessary to actually confirm the adjustment state by playing the game ball. However, the conversion is performed so that the confirmation operation can be performed early without waiting for a predetermined time. If a launch operation is performed during the control, a transition is made preferentially to launch control and ball feed control (1.02 → 1.10, 1.11).
[0024]
Further, if the rotary solenoid 36 is continuously energized during the conversion control, the amount of heat generation becomes large. Therefore, as shown in FIG. 8, a predetermined short time from the start of the conversion control (the firing lever 19 is moved from the start position to the bullet position). The energization of the rotary solenoid 36 is continued for an operating time required to move to the position of, for example, 0.5 seconds. After that time, the firing lever 19 returns to the starting position by its own weight based on the intermittent timer. The energization state to the rotary solenoid 36 is intermittently controlled so as to ensure the minimum holding force for suppressing the pressure (2.01 to 2.10). FIG. 7 is a subroutine for explaining the control contents performed in step 1.04 in the main routine of FIG.
[0025]
With such a configuration, when the operation unit 7 of the ball hitting device 20 is normally fired in the normal state of the pachinko machine, the rotary solenoid 36 and the ball supply mechanism are driven synchronously, and the game is started from the supply tray 4 on the front surface of the pachinko machine. While the balls are sent one by one onto the firing rail 31, they are continuously launched toward the game board with a firing force corresponding to the operation angle of the handle 26.
[0026]
In this case, the firing lever 19 is driven by a rotary solenoid 36 that rotates forward and backward in accordance with switching of the flow direction of the supply current, and the firing operation and the return operation are alternately repeated by the driving force. Compared to the case of energizing with electromagnetic force (return operation depends on spring force and dead weight), quick and stable and reliable hitting of the ball is obtained, and there is no switching to the launch operation from the middle of the slow return operation, Effective prevention of unevenness of game balls can be achieved.
[0027]
By the way, the tip of the launch lever 19 changes over time due to the impact of launching the game ball, but when the tip adjustment is necessary, the front panel where the supply tray 4 is located is opened and the push button 8 on the front frame is turned on. Then, the rotary solenoid 36 receives a supply current in one direction and continuously urges the firing lever 19 to the bullet position for a predetermined time as shown in FIG. It can be done easily.
[0028]
That is, it is not necessary to open the front frame 1 and adjust it from the back side as in the past, or to instantaneously catch the firing lever 19 at the bullet position by the firing operation on the front side. The adjustment operation is repeated as necessary while confirming the launching of the game ball at the same time. However, the firing lever 19 can be stopped at the bullet position by a simple operation of the push button 8 each time. The tip adjustment can be processed much more efficiently.
[0029]
In addition, the rotary solenoid 36 is not continuously energized for a predetermined time when adjusting the tip of the firing lever 19, but the energized state is continued only for a short time necessary to move the firing lever 19 from the starting position to the bullet position. At the same time, the energization state is intermittently controlled so as to ensure the minimum holding force with respect to the firing lever 19 based on the intermittent timer after the lapse of time, so that the firing of the rotary solenoid 36 is suppressed to a small amount. It is also possible to extend the stop time of the lever 19 (time setting for conversion control).
[0030]
In this example, if a firing operation is performed during the conversion control for the launch lever 19, priority is given to the control so that the confirmation work can be started without waiting for the end of the conversion control. Cancels the firing operation performed during the control, or if the firing control (including ball feed control) is temporarily stopped by giving priority to the firing operation, it is pressed during the conversion control operation period. Instead of turning on the button 8, the firing lever 19 may be stopped again at the bullet position for the remaining time.
[0031]
In addition, the front frame 1 is provided with a dedicated push button 8 for generating an adjustment request. When the pachinko machine is turned on, an adjustment request is generated each time, or an existing switch is used, for example, a ball hitting operation. The control program may be configured so that an adjustment request is generated when the push button 30 or the handle 26 of the unit is operated in a specific pattern.
[0032]
Note that the conversion control for stopping the firing lever 19 in the adjusted state is not limited to the rotary solenoid type launching device 20, but the firing operation is performed by a plunger type solenoid, and the return operation to the starting position is performed by a spring force or the like. The invention can be widely applied to those depending on its own weight, and in some cases, a dedicated solenoid may be added as a conversion drive means to be controlled separately from these firing drive means.
[0033]
