A sound control device 49 or the like for controlling the output is provided.

  FIG. 3A is a diagram illustrating a circuit configuration of the launch control device 43. The firing control device 43 includes a rectifier circuit 51, a smoothing capacitor C1, a solenoid driving transistor 52, a solenoid (a solenoid equivalent circuit is shown in the figure) 53, a back electromotive force clamping diode D, a current A detection resistor R1, a drive timing sequence circuit 54, a synchronization transistor 55, a solenoid current adjustment DC power source 56, a waveform generation circuit 57, a voltage comparator 58, and a transistor drive circuit 59 are provided. Yes.

  The rectifier circuit 51 performs full-wave rectification on the AC voltage supplied from the AC power supply AC and outputs a DC voltage. The smoothing capacitor C1 smoothes the DC voltage output from the rectifier circuit 51. This smoothed DC voltage is defined as a power supply voltage E.

  The solenoid drive transistor 52 repeats the on / off operation based on the constant current target value set in the solenoid drive signal supplied to the base electrode by the transistor drive circuit 59, and the solenoid drive current corresponding to the on / off operation is solenoided. It flows in the equivalent circuit 53.

  The solenoid equivalent circuit 53 is an equivalent circuit of the solenoid in the above-described launching unit, and includes an equivalent inductance L and an equivalent series resistance R. The solenoid equivalent circuit 53 repeats the excitation / non-excitation operation according to the solenoid drive current that the solenoid driving transistor 52 flows, and adjusts the rotation operation cycle and the striking force of the above-described firing by the excitation / non-excitation operation.

  That is, in proportion to the solenoid drive current that the solenoid drive transistor 52 passes through the solenoid equivalent circuit 53, the number of times the above-mentioned launch? 31 strikes the game ball within a predetermined time (for example, 1 minute), and the hit given to the game ball Power is determined. The pachinko machine 1 is assumed to fire 100 game balls per minute, and a drive timing sequence circuit, which will be described later, so that the pulse repetition frequency set in the solenoid drive signal oscillates under this condition. 54 is configured.

  The back electromotive force clamping diode D is connected in parallel to the solenoid equivalent circuit 53 and absorbs the back electromotive force generated during excitation by the solenoid equivalent circuit 53. The current detection resistor R1 detects a solenoid current flowing through the solenoid equivalent circuit 53, and outputs a current detection signal corresponding to the detected current to the inverting input terminal (−) of the voltage comparator 58.

  The drive timing sequence circuit 54 receives the fact that the handle switch of the operation handle 21 is turned on, generates a pulse signal having a predetermined repetition frequency for determining the number of times of firing within the predetermined time, and outputs the pulse signal. This is supplied to the base electrode of the synchronization transistor 55.

  The DC power source 56 for adjusting the solenoid current generates a target DC voltage for adjusting the solenoid current to a predetermined target current value according to the resistance value r of the variable resistor that changes according to the operation of the operation handle 21 described above. To the synchronization transistor 53.

  The synchronization transistor 55 repeats an on / off operation in response to a pulse signal supplied to the base electrode by the drive timing sequence circuit 54, and a constant current target of the solenoid current (in accordance with a target DC voltage generated by the solenoid current adjusting DC power source 56) A synchronization signal in which an upper limit and a lower limit are set is generated and output to the waveform generation circuit 57.

  The waveform generation circuit 57 includes an integration circuit including a waveform generation resistor R2 and a waveform generation capacitor C2, and a discharge resistor R3. The waveform generation circuit 57 generates a solenoid constant current control target pattern waveform from the synchronization signal output from the synchronization transistor 53 and outputs it to the non-inverting input terminal (+) of the voltage comparison circuit 58. The waveform generation circuit 58 discharges the electric charge charged in the waveform generation capacitor C2 after the waveform generation by the discharging resistor R3.

  The voltage comparator 58 comprises an operational amplifier, compares the current detection signal output from the current detection resistor R1 with the solenoid constant current control target pattern waveform output from the waveform generation circuit 58, and determines the solenoid drive current based on the comparison result. A solenoid constant current control signal for controlling the signal is generated and output to the transistor drive circuit 59.

  Based on the solenoid constant current control signal output from the voltage comparison circuit 55, the transistor drive circuit 59 generates a solenoid drive signal for making the solenoid current constant, and supplies it to the base electrode of the solenoid drive transistor 52.

  Next, the operation of the first embodiment will be described.

  The solenoid current adjustment operation of the firing control device 43 shown in FIG. 3A will be described with reference to FIGS. 4A shows an example of the transition of the solenoid current during constant current control and an example of the transition of the solenoid current i when there is no control, and FIG. 4B shows an example of a pulse signal during the output ON period of the drive timing sequence circuit 54. Indicates. 5A shows a transition example of the solenoid current during the constant current control when the power supply voltage is high, and FIG. 5B shows an example of the pulse signal in the output ON period of the drive timing sequence circuit 54. FIG. 6A shows an example of transition of the solenoid current during constant current control when the power supply voltage is low, and FIG. 6B shows an example of a pulse signal during the output ON period of the drive timing sequence circuit 54. 4A to 6A, the vertical axis represents the solenoid current I [A], and the horizontal axis represents the time t [s].

  In FIG. 4A, the solid line shows the transition of the solenoid current during the constant current control according to the present embodiment, and the broken line shows the solenoid current transition i during the non-control.

  When the player operates the operation handle 21, the handle switch is turned on, and the drive timing sequence circuit 54 starts oscillating a pulse signal. In this case, the drive timing sequence circuit 54 outputs an on signal to the base electrode of the synchronization transistor 55 during the on period of the drive timing sequence circuit 54 shown in FIG. 4B, and outputs an off signal during the other periods. The cycle in which the game ball is repeatedly fired is determined by the repetition frequency of the on signal and the off signal. As a result of comparison by the operational amplifier 58, a pulse signal having a predetermined repetition frequency as shown in FIG. The amount of power for driving the solenoid equalization circuit 53 is determined by the pulse repetition frequency of this pulse signal.

  Further, the resistance value r of the variable resistor is changed by the operation of the operation handle 21 at this time, and the saturation value of the solenoid driving signal followed by the solenoid driving current flowing in the solenoid equivalent circuit 53 is determined by this resistance value r, The hitting power against? 31 game balls is determined.

  Like the transition of the solenoid current during the constant current control indicated by the solid line in FIG. 4A, the rise time t of each pulse set by the solenoid drive signal is for waveform generation that constitutes the integration circuit in the waveform generation circuit 57. It is determined by the time constant τ = r2 · c2 between the resistance value r2 of the resistor R2 and the capacitance c2 of the waveform generating capacitor C2, and the saturation current is determined by the resistance value r of the variable resistor. Therefore, since the time constant τ = r 2 · c 2 is constant, a constant curve can be obtained at each pulse of the solenoid drive signal, and the solenoid drive current flowing in the solenoid equivalent circuit 53 following this solenoid drive signal. Will be determined.

  That is, when the constant current control according to the present embodiment is not performed as in the current transition i during no control indicated by the broken line in FIG. 4A, the power supply voltage E supplied by the rectifier circuit 51 and the smoothing capacitor C1. Under the influence of fluctuations (at the time of high power supply voltage, standard power supply voltage, and low power supply voltage), the curves from the rise of the solenoid drive current to saturation become different, the solenoid drive current fluctuates, and the launch? 31 The striking force that the ball gives to the game ball is not constant.

  On the other hand, as described above, the firing control device 43 of the present embodiment determines the striking force applied to the game ball based on the resistance value r of the variable resistor obtained by the player's handle operation, and the solenoid drive signal The rise time t of each pulse set by the above is a time constant τ = r 2 · c 2, and all the pulses are constant, so that a solenoid driving current corresponding to the resistance value r can always flow, and a constant striking force can be obtained. It can be given to a game ball and does not fluctuate as in the case of no control described above.

  On the other hand, the solenoid current flowing through the solenoid equivalent circuit 53 is detected by the current detection resistor R1 and input to the inverting input terminal (−) of the voltage comparator 58 as a current detection signal. Further, a target DC voltage for adjusting the solenoid current is generated by the DC power source 56 for adjusting the solenoid current according to the resistance value r of the variable resistor. The synchronization transistor 55 and the waveform generation circuit 57 generate a solenoid constant current control target pattern waveform including a constant current target (upper limit value and lower limit value) as indicated by a solid line in FIG. Input to the non-inverting input terminal (+) of the voltage comparator 58.

  The voltage comparator 53 compares the voltage levels of the current detection signal input to the inverting input terminal (−) and the solenoid constant current control target pattern waveform input to the non-inverting input terminal (+), and the current detection signal is a solenoid. When it is larger than the constant current control target pattern waveform, a “Hi” signal is output, and when the current detection signal is smaller than the solenoid constant current control target pattern waveform, a “Low” signal is output.

  That is, when the detected current at the inverting input terminal (−) of the voltage comparator 53 is smaller than the solenoid constant current control target pattern waveform input to the non-inverting input terminal (+), the inverting input terminal (−) “Low”, the non-inverting input terminal (+) becomes “Hi”, and a solenoid constant current control signal for increasing the solenoid drive current of the solenoid drive transistor 52 is output to the transistor drive circuit 59. The transistor drive circuit 59 outputs a “Hi” signal to the base electrode of the solenoid drive transistor 52 in response to the input of the solenoid constant current control signal that increases the solenoid drive current, and the solenoid drive current that flows to the solenoid equivalent circuit 53 is output. increase. As a result, the detection current flowing through the current detection resistor R1 also increases.

  When the detection current flowing through the current detection resistor R1 also becomes large, the detected current at the inverting input terminal (−) of the voltage comparator 53 is the solenoid constant current control target pattern waveform that is input to the non-inverting input terminal (+). The inverting input terminal (−) becomes “Hi”, the non-inverting input terminal (+) becomes “Low”, and a solenoid constant current control signal for reducing the solenoid driving current of the solenoid driving transistor 52 is supplied to the transistor driving circuit 59. Output to. The transistor drive circuit 59 outputs a “Low” signal to the base electrode of the solenoid drive transistor 52 in response to the input of the solenoid constant current control signal that decreases the solenoid drive current, and generates a solenoid drive current that flows to the solenoid equivalent circuit 53. Decrease. As a result, the detection current flowing through the current detection resistor R1 also decreases. In this way, the firing control device 43 executes feedback control so that the solenoid current detected by the current detection resistor R1 follows the solenoid constant current control target pattern waveform.

  Therefore, the solenoid current (at the time of the standard power supply voltage) at the time of the constant current control indicated by the solid line in FIG. 4A is the same as that of the firing control device 43 when the power supply voltage E is the standard power supply voltage. This is the result of feedback control to follow the current control target pattern waveform. The constant current target (upper limit) and the constant current target (lower limit) indicated by the alternate long and short dash line in the change of the solenoid current are a waveform generation circuit corresponding to the pulse period (on time and off time) of the pulse signal shown in FIG. This is a constant current target value including the solenoid constant current control target pattern waveform generated in 57.

  Further, the solenoid current (at the time of high power supply voltage) at the time of constant current control indicated by a solid line in FIG. 5 (a) indicates that when the power supply voltage E is higher than the standard power supply voltage, the above-described launch control device 43 is a solenoid. This is the result of feedback control so that the current follows the solenoid constant current control target pattern waveform. The solenoid current (at the time of low power supply voltage) at the time of constant current control indicated by the solid line in FIG. 6 (a) indicates that the above-described launch control device 43 generates the solenoid current when the power supply voltage E is lower than the standard power supply voltage. This is a result of feedback control so as to follow the solenoid constant current control target pattern waveform.

  As described above, even when the power supply voltage E is a high power supply voltage or a low power supply voltage, each solenoid constant current control target pattern waveform follows the pulse width of the pulse signal and changes similarly exponentially. It will be a thing. In each solenoid constant current control target pattern waveform, even if the pulse width of the pulse signal fluctuates at high power supply voltage or low power supply voltage, the target solenoid current value is constant for each pulse. As a result, the constant current target value determined by the resistance value r of the variable resistor that is changed by the steering operation is constant without being affected by the fluctuation of the power supply voltage E, and a constant solenoid driving current is always supplied to the solenoid. The game ball can be launched with a constant hitting force.

  When the player stops operating the operation handle 21 and the handle switch is turned off, the drive timing sequence circuit 54 stops the oscillation of the pulse signal, the base electrode of the synchronization transistor 55 is also turned off, and the solenoid drive transistor 52 is also turned off. Thus, the detected current is also 0, and the launching device 44 is in a non-operating state. If the voltage comparator 58 shown in FIG. 3 (a) is not strictly configured as the modified example of the voltage comparator 58 shown in FIG. 3 (b), an upper limit value and a lower limit value are set as constant current targets. However, when the solenoid current exceeds the constant current target, an off signal is output to the transistor drive circuit 59, and when the solenoid current is lower than the constant current target, the on signal is output in a very short cycle. In this modified example, the output of the voltage comparator 58 and the input to the non-inverting input terminal (+) are connected to hysteresis so that when the solenoid current reaches the constant current target, the constant current target is lowered and below the lowered constant current target. This can be realized by setting the resistance values of the resistors R4 and R5 so that the constant current target is increased. Further, the output of the voltage comparator 58 is increased by a pull-up voltage via the resistor R6. With such a configuration, the solenoid current can be controlled to vary between the upper limit value and the lower limit value of the constant current target.

  (Embodiment 2)

  FIG. 7 is a diagram illustrating a circuit configuration of the launch control device 70 according to the second embodiment. In this launch control device 70, the same reference numerals are given to the same components as those in launch control device 43 shown in FIG. The front side configuration and the back side configuration of the pachinko machine 1 according to the second embodiment are the same as those shown in FIGS. 1 and 2 of the first embodiment, and therefore illustration and description of the configuration are omitted. .

  7 includes a rectifier circuit 51, a smoothing capacitor C1, a solenoid driving transistor 52, a solenoid equivalent circuit 53, a back electromotive force clamping diode D and a zener diode ZD, and a current detection resistor. R1, drive timing sequence circuit 54, solenoid current adjustment DC power supply 56, voltage comparator 58, transistor drive circuit 59, and current waveform integration circuit 71.

  The drive timing sequence circuit 54 determines the maximum drive period of the solenoid equivalent circuit 53 in response to the fact that the handle switch of the operation handle 21 is turned on and the resistance value r of the variable resistor determined by the operation position. The setting (see FIGS. 8C and 8F) is output to the transistor drive circuit 59.

  The current waveform integration circuit 71 includes a waveform generation resistor R2, a waveform generation capacitor C2, and an operational amplifier OP. The current waveform integration circuit 71 generates a current detection signal corresponding to the solenoid current output from the current detection resistor R1 as a time constant τ composed of the resistance value r2 of the waveform generation resistor R2 and the capacitance c2 of the waveform generation capacitor C2. = R2 · c2 is integrated, and the integrated waveform is output to the inverting input terminal (−) of the voltage comparator 58.

  The voltage comparator 58 compares the integration waveform output from the current waveform integration circuit 71 with the solenoid current adjustment DC voltage output from the solenoid current adjustment DC power source 56, and determines the solenoid constant that controls the solenoid drive current based on the comparison result. A current control signal is generated and output to the transistor drive circuit 59.

  The transistor drive circuit 59 generates a solenoid drive signal based on the drive period setting signal output from the drive timing sequence circuit 54 and the solenoid constant current control signal output from the voltage comparator 58 and supplies the solenoid drive signal to the solenoid drive transistor 52. To do.

  Next, the operation of the second embodiment will be described.

  The solenoid current adjustment operation of the firing control device 70 shown in FIG. 7 will be described with reference to FIG. 8A is a diagram showing a relationship between a detected current transition curve and a detected current integrated value at a high power supply voltage, FIG. 8B is a diagram showing an output ON period of the transistor drive circuit 59, and FIG. 8C is a drive timing. The figure which shows the output on period of the sequence circuit 54, (d) is a figure which shows the relationship between the detection current transition curve at the time of a low power supply voltage, and a detection current integral value, (e) is a figure which shows the output on period of the transistor drive circuit 59 (F) is a figure which shows the output ON period of the drive timing sequence circuit 54. FIG. In FIGS. 4A and 4D, the left vertical axis is the integrated value [A · S] of the detected current value, the right vertical axis is the detected current value [A], and the horizontal axis is the time t [s]. It is.

  In FIG. 8A, a thick solid line indicates an integrated value of a detected current value at a high power supply voltage by constant current control according to the present embodiment, and a thin solid line indicates a detected current transition curve at a high power supply voltage. Further, the broken line shows the transition of the current value when the current is passed through the solenoid even after the output of the transistor drive circuit 59 is turned off.

  When the player operates the operation handle 21, the handle switch is turned on, and the drive timing sequence circuit 54 starts solenoid driving.

  Further, the resistance value r of the variable resistor is changed by the operation of the operation handle 21 at this time, and the target value of the solenoid driving signal followed by the solenoid driving current flowing through the solenoid equivalent circuit 53 is determined by this resistance value r, The hitting power against? 31 game balls is determined.

  FIGS. 8A to 8C show respective waveforms when the power supply voltage E supplied by the rectifier circuit 51 and the smoothing capacitor C1 is higher than the standard power supply voltage. FIGS. Each waveform when the power supply voltage E is lower than the standard power supply voltage is shown. As shown in FIGS. 5B and 5E, the output ON period of the transistor drive circuit 59 varies even when the resistance value r is constant and the target value is constant. This is because the drive timing sequence circuit 54 is affected by fluctuations in the voltage value of the power supply voltage E. Due to the fluctuation of the output ON period of the transistor drive circuit 59, the rising time t1 until the target value is reached as shown in the integrated values of FIGS. It will be different from time to time.

  However, the DC voltage value for adjusting the solenoid current generated by the DC power supply 56 for adjusting the solenoid current according to the resistance value r of the variable resistor is not affected by the fluctuation of the power supply voltage E, and FIGS. As shown in (2), the target value does not vary and is constant when the power supply voltage is high and when the power supply voltage is low. For this reason, the voltage comparator 58 compares the integrated value of the detected current value input to the inverting input terminal (−) with a constant target value when the power supply voltage is high and when the power supply voltage is low. That is, the voltage comparator 58 outputs a “Hi” signal as the solenoid constant current control signal when the integral value is smaller than the target value, and the solenoid constant current control when the integral value is larger than the target value. A “Low” signal is output as a signal.

  By the constant current control of the voltage comparator 58, the solenoid drive current is caused to flow through the solenoid equivalent circuit 53 during the period of time t1 until each integrated value shown in FIGS. 8A and 8D reaches the target value. The transistor drive circuit 59 is controlled. As a result, in each of the integral values shown in FIGS. 8A and 8D, the hatching area corresponding to the solenoid drive current amount flowing during the time t1 until the target value is reached is at the time of the high power supply voltage and the low power supply voltage. It becomes constant over time.

  Therefore, even when the power supply voltage E fluctuates and the output on period of the transistor driving circuit 59 fluctuates, the target value of the solenoid driving current is set constant by the resistance value r of the variable resistor obtained by the player's handle operation. Therefore, the solenoid driving current flowing through the solenoid can be controlled to be constant, and the game ball can be launched with a constant striking force by the launch? 31.

  8A to 8F are diagrams showing waveforms for a period in which a game ball is fired once. The firing control device 70 repeatedly executes similar constant current control corresponding to the waveforms shown in these drawings so that the launch? 31 sequentially fires the game balls with a constant striking force.

  When the player stops the operation of the operation handle 21 and the handle switch is turned off, the drive timing sequence circuit 54 stops outputting the drive period setting signal, the solenoid driving transistor 52 is also turned off, and the detection current becomes 0, The launcher 44 is in a non-operating state.

  In the gaming machine of the present invention (for example, the pachinko machine 1), a solenoid for changing the firing state of the launching means for launching the game ball into the game area (for example, the launch? 31 equipped with the kite 32) from the standby state to the launch state; A current value control circuit (for example, a launch control device 43) that controls the change pattern of the current value that flows when the solenoid is operated to be a specific change pattern. Even in this case, a stable striking force may be obtained.

  In the gaming machine of the present invention (for example, the pachinko machine 1), the current value control circuit includes a current detection means (for example, a current detection resistor R1) for detecting a solenoid current value flowing through the solenoid, and a player. Based on the target current value setting means (for example, the DC power supply 56 for solenoid current adjustment) that sets the target current value according to the firing intensity adjustment operation by the target current value set by the target current value setting means, the A waveform generation means (for example, waveform generation circuit 57) for generating a target change pattern waveform of the solenoid current value is compared with a detected current value detected by the current detection means and a target change pattern waveform generated by the waveform generation means. And a current value comparison means (for example, a voltage comparator 58) for controlling the current value change pattern to be the target change pattern based on the comparison result. Therefore, the constant current target value determined by the resistance value of the variable resistor that is changed by the player's launch intensity adjustment operation is constant without being affected by fluctuations in the power supply voltage, and is always constant with respect to the solenoid. In some cases, a game ball can be launched with a constant hitting force.

  In the gaming machine of the present invention (for example, the pachinko machine 1), the current value control circuit is a pulse oscillating unit that oscillates a pulse signal having a predetermined period for setting a firing period of the game ball in accordance with the launch intensity adjusting operation ( For example, a drive timing sequence circuit 54) and synchronization signal generation means (for example, a synchronization transistor 55) for generating a synchronization signal in which the target current value is set based on a pulse signal oscillated by the pulse oscillation means. In addition, since the waveform generation means generates the target change pattern waveform based on the synchronization signal generated by the synchronization signal generation means, even when the power supply voltage varies and the solenoid drive period varies, When the target value of solenoid drive current can be set constant by the resistance value of the variable resistor obtained by the player's launch intensity adjustment operation A.

  In the gaming machine of the present invention (for example, the pachinko machine 1), the current value control circuit integrates the detected current value detected by the current detecting means with a predetermined time constant and outputs an integrated value (detected current integrating means ( For example, the current waveform integration circuit 71) compares the target current value set by the target current value setting means with the integral value output by the detection current integration means, and the current value is calculated based on the comparison result.

  In addition to the configuration where the launching means is provided with a spear at the tip of the launching, two rotating bodies that rotate while sandwiching the game ball are driven to rotate by a solenoid, and the game ball is released by a solenoid drive or It can also be applied to throwing-type launching means. Further, while the drive timing sequence circuit 54 outputs an on signal, the circuit configuration of the solenoid or solenoid equivalent circuit 53 and the diode D is switched by a relay or the like while the transistor drive circuit 59 outputs an off signal. Then, the electromotive force of the coil constituting the solenoid is stored in a capacitor (for example, capacitor C1), and when the transistor drive circuit 59 is switched to output an ON signal, the above relay is switched to return to the original circuit configuration, The power stored in the capacitor may be allowed to flow to the solenoid. By doing so, there is a case where it is possible to save useless power such that the back electromotive force of the coil constituting the solenoid is simply changed into heat and to promote effective use of the power.
