Description

The present invention relates to a gaming machine having a configuration in which the accuracy of the firing motion of the gaming ball can be stably maintained and adverse effects on the computer circuit can be avoided.

A ball game machine such as a pachinko machine is equipped with a symbol start port provided on the game board, a symbol display unit for displaying a series of symbol variation modes by a plurality of display symbols, and a large winning opening for opening and closing the opening / closing plate. It is composed of. Then, when the detection switch provided at the symbol start port detects the passage of the game ball, the winning state is set, and after the game ball is paid out as the prize ball, the displayed symbol is changed for a predetermined time on the symbol display unit. After that, when the symbol is stopped in a predetermined mode such as 7, 7, 7, a big hit state is reached, and the big winning opening is repeatedly opened to generate a game state advantageous to the player.

Whether or not to generate a big hit game state is determined by a big hit lottery executed on the condition that a game ball wins a prize at the symbol start opening, and the above symbol fluctuation operation is based on this lottery result. It has become. For example, when the lottery result is in the winning state, an effect operation called a reach action or the like is executed for about 20 seconds, and then special symbols are arranged.

By the way, in this type of game machine, the above lottery process is not executed unless the game ball wins a prize at the symbol start port. Therefore, the player moves to the target position by appropriately changing the rotation position of the firing handle. Is firing a game ball. Specifically, a game ball guided to a launch position corresponding to the operation of the ball feed solenoid is launched by a striking mallet that operates in response to the launch solenoid (Patent Documents 1 and 2).

For example, in the configuration of Cited Document 2, the acceptance operation of accepting the game ball to be followed by the game ball at the launch position to the standby position and the movement of the game ball at the standby position while blocking the movement of the subsequent game ball are performed. The outflow operation is switched based on the energization of the ball feed solenoid. Further, in Cited Document 1, a solenoid ON operation (FIG. 11 (a)) in which only the most advanced game ball is moved to the launch position while the subsequent movement of the game ball is blocked, and the movement of the most advanced game ball are described. The solenoid OFF operation (FIG. 11B) that allows the subsequent movement of the game ball while preventing the movement of the game ball is disclosed.

As mentioned above, the accuracy of the launching motion of the gaming ball is extremely important for this type of gaming machine, and a one-to-one relationship is essential between the rotation position of the launching handle and the striking strength of the striking mallet on the gaming ball. Therefore, the arrival position of the game ball must not vary.

However, since various movable accessories are arranged in recent game machines and a flashy lamp effect is also executed, the potentials of the power supply line and the ground line may fluctuate to some extent.

Then, if the firing solenoid is operated while the potentials of the power supply line and the ground line fluctuate, the correct firing rate cannot be maintained. Further, if the energized state of the ball feed solenoid fluctuates greatly, accurate firing operation cannot be guaranteed. On the other hand, it is also necessary to prevent the noise of the power supply line accompanied by the ON / OFF operation of various solenoids from adversely affecting other computer circuits.

The present invention has been made in view of the above problems, and provides a gaming machine having a configuration capable of stably maintaining the accuracy of the launching motion of a gaming ball and avoiding an adverse effect on a computer circuit. With the goal.

FIG. 3 is a block diagram showing the overall circuit configuration of the pachinko machine GM that realizes each of the above operations, and shows a game machine that is connected to the hall computer HC and the ball lending machine LEN and operates by receiving AC24V. There is. Various game information INFs and abnormality information are transmitted to the hall computer HC, and various information is transmitted and received between the ball lending machine LEN and the game machine GM during the ball lending operation.

As shown in FIG. 3, this game machine GM is mainly responsible for the game control operation and the power supply board 20 that receives AC24V and outputs three types of DC voltages (5V, 12V, 35V) to two systems. A display device based on the main control board 21, an effect control board 22 that executes a lamp effect and a sound effect based on the control command CMD received from the main control board 21, and a control command CMD'received from the effect control board 22. It is mainly composed of an image control board 23 for driving a DS and a payout control board 24 for controlling a payout motor Mo to pay out a game ball based on a control command SYO received from the main control board 21.

The control command CMD output from the main control board 21 is first transmitted to the effect control board 22, and the control command CMD'output from the effect control board 22 is the image interface board 37 together with the 1-bit length strobe signal STB. Is transmitted to the image control board 23 via the above. On the other hand, the control command SYO for the prize ball output from the main control board 21 is transmitted to the payout control board 24 via the main board relay board 34.

The control command CMD and the control command CMD'are 16-bit length parallel data, and are transmitted in parallel from the main control board 21 to the image control board 23 in two steps every 8 bits. Therefore, the command transmission line from the main control board 21 to the image control board 23 has a total length of 9 bits including the strobe signal STB.

On the other hand, the control command CMD'transmitted from the effect control board 22 to the image control board 23 is collectively transmitted in parallel with a 16-bit length. Therefore, the command transmission line from the effect control board 22 to the image control board 23 has a total length of 17 bits including the strobe signal STB', but even if a large number of control commands are continuously transmitted and received, the processing can be performed quickly. There is an advantage that can be finished.

In addition, all or a part of the effect control unit 22, the image control unit 23, and the payout control unit 24 are sub control units.

<Power supply board 20 as a component>
First, in this embodiment, the circuit configuration of the power supply board 20 is simplified to realize the componentization of the power supply board that does not require public inspection. Specifically, the power supply board 20 receives three types of DC voltages (35V, 12V, 5V), a rectifier circuit that rectifies AC24V, a power factor improvement circuit that receives the output of the rectifier circuit, and a power factor improvement circuit that receives the output of the power factor improvement circuit. ) Is a step-down DC / DC converter, and the power reset signal RST indicating power on / off and the power failure signal ABN are not output.

Corresponding to this configuration, in this embodiment, the power supply reset signals RST (RST1 to RST3) are respectively based on the DC voltage distributed to the payout control board 24, the main control board 21, and the effect control board 22. Will be generated. Specifically, first, as shown in FIG. 4, the payout control board 24 and the main control board 21 are each DC based on two types of DC voltages (12V, 5V) distributed from the power supply board 20. In the determination circuits JG1 and JG2, the power supply reset signals RST1 and RST2 are generated to reset the power supply of the internal circuit.

Similarly, the effect control board 22 and the image control board 23 also generate a power supply reset signal RST3 based on the two types of DC voltages (12V, 5V) distributed, and inside the effect control board 22 and the image control board 23. The circuit is power reset.

Further, the DC determination circuit JG1 of the payout control board 24 generates a power interruption signal ABN based on the AC voltage AC24V distributed to the payout control board 24, and generates a power interruption signal ABN, and the one-chip microcomputer MCOM4 and the one-chip of the main control board 21. It is transmitted to the microcomputer MCOM1.

As described above, in the embodiment, since the power supply reset signal RST and the power failure signal ABN that affect the game control operation are not output from the power supply board 20, there is virtually no risk of misuse or modification of the power supply board 20, and it is publicly available. Confirmation inspection at a target institution is not required.

<Backup power supply board 27>
Further, in this embodiment, the backup power supply board 27 in which the electric double layer capacitor Cbc is arranged is provided separately from the power supply board 20 and the payout control board 24, and the payout control board 24 receives the DC voltage from the power supply board 20. VBB (5V) is supplied to the backup power supply board 27 through the power supply line VBB to charge the electric double layer capacitor Cbc (see FIG. 4). After the power failure, the charging voltage VBB of the electric double layer capacitor Cbk functions as the backup power supply VBB of the one-chip microcomputers MCOM4 and MCOM1 mounted on the payout control board 24 and the main control board 21, and each one-chip microcomputer has a charge voltage VBB. The stored contents of the built-in RAM are reliably maintained.

<Power distribution path from the power supply board>
Next, the distribution path of the DC voltage generated by the power supply board 20 and the like will be organized. FIG. 5 shows the internal configuration of the power supply board 20 in which the power factor improving circuit is omitted and only the portion related to the payout control unit 24 is shown. The power supply board 20 is further provided with three sets of power supply circuits similar to those shown in the drawing, and the three types of DC voltages 35, 12V, and 5V generated by the three sets of power supply circuits (not shown) are connected to the connector C2. Power is distributed to the effect control board 22 via the power supply relay board 35. Then, two types of DC voltages (12V, 5V) are distributed to the image control board 23 via the effect control board 22 and the image interface board 37.

On the other hand, the DC determination circuit JG1 has been described above with respect to the power supply board 20, and has generated the power supply reset signal RST1 based on the DC voltage (12V, 5V) and cut off the AC power supply (AC24V). Detects and generates a power failure signal ABN.

In this embodiment, the drive signals Φ1 to Φ4 for rotationally driving the payout motor Mo are generated by the one-chip microcomputer MCOM4 and transmitted to the motor driver DR whose power supply voltage is a DC voltage of 12 V. On the other hand, the launch solenoid SLe and the ball feed solenoid SLf are not based on the control of the one-chip microcomputer MCOM4, but based on the fixed set values to the lead terminals of the launch control circuit element SH and the output signal of the launch intensity volume VR. The energization time, energization timing, energization cycle, and the like are controlled by the launch control circuit element SH.

However, in order for the launch control circuit element SH to start the launch control operation, (1) the ball lending machine LEN is normally connected, and (2) the launch permission signal SHOOT is received from the main control unit 21. Is the operation start condition. Further, when (3) the player releases the firing handle 10 or (4) the player instructs to stop firing, the firing control circuit element SH naturally stops the firing operation (operation). Stop condition).

In relation to the above-mentioned operation start condition, the launch control circuit element SH is connected to the ball lending machine LEN via the ball lending relay unit LK1 and the relay board LK2, and the connection state with the ball lending machine LEN is changed. It is designed to receive the indicated energization signal POUT. Further, the launch control circuit element SH is circuit-connected so as to receive a launch permission signal SHOOT from the one-chip microcomputer MCOM1 of the main control unit 21.

By the way, this emission control circuit element SH is composed of a single element of SIP (Single Inline Package) type in which a large number of electronic elements related to emission control are built (FIG. 6). However, the present invention is not particularly limited, and a single element of DIP (Dual Inline Package) type may be used.

In any case, the circuit components of the payout control board 24 that realizes the above configuration are not the surface mount type, but are all unified to the through-hole mount type, and all the circuit components are direct or IC sockets. The lead terminals of each circuit component are inserted from the front surface of the substrate and soldered from the back surface side. Therefore, by adopting the flow soldering method or the like, the soldering work can be completed quickly. Further, since there is no circuit component on the back surface side of the payout control board 24, not only the payout control unit 24 can be made thinner, but also the inspection process at the inspection organization can be speeded up.

Further, solid earth surfaces are formed on the substrate surface and the substrate back surface of the payout control substrate 24, respectively. Here, the solid ground surface is a circuit board surface in which all parts excluding the signal pattern connecting the components and the power supply pattern for supplying the power supply voltage are ground surfaces, and low impedance is realized. At the same time, the noise resistance is improved.

Further, the board surface of the payout control board 24 and the solid ground surface on the back surface of the board are divided into a first ground surface A_GND and a second ground surface D_GND by an isolation line, respectively, and flow through the two ground surfaces A_GND and D_GND. Measures are taken to prevent the return current from being mixed. This point is as described above, and only the return current of the solenoid drive voltage (DC voltage 35V) flows through the first ground surface A_GND.

In addition, (1) all circuit components are unified to the through-hole mounting type, and they are inserted from the front surface of the board and soldered from the back surface side, (2) there are no circuit components on the back surface of the board, and ( 3) The fact that the solid ground surface is divided into the first ground surface A_GND and the second ground surface D_GND by the isolation line is the same not only for the payout control board 24 but also for the main control board 21.

Based on the above, the payout control board 24 will be described. As shown in FIG. 4, a DC voltage of 35 V and a DC voltage of 5 V are supplied to the launch control circuit element SH as two types of power supply voltages.

Here, the DC voltage 5V supplied to the launch control circuit element SH is distinguished from the one-chip microcomputers MCOM1 and MCOM4 and the power supply voltage 5V of the logic circuits related thereto, and is stabilized by lowering the DC voltage 12V. It is generated by the power circuit REG. Therefore, it is possible to prevent the logical operation of the launch control circuit element SH from adversely affecting the one-chip microcomputer of the main control unit 21 and the payout control unit 24 and other circuit elements via the power supply line having a power supply voltage of 5 V. Will be done.

Corresponding to the above configuration of the payout control board 24, the signal relay board 25 transfers the drive signals Φ1 to Φ4 received from the motor driver DR to the payout motor Mo and rotationally drives the payout motor Mo (FIG. 3). ). Further, the signal relay board 25 receives detection signals from various detection sensors and transfers them to the one-chip microcomputer MCOM4 of the payout control board 24.

The detection signal received by the signal relay board 25 is not particularly limited, but in this embodiment, the door frame opening signal indicating that the glass door 6 and the front frame 3 have been opened, and the game ball are clogged and cannot be paid out. A ball jam detection signal indicating that there is no game ball to be paid out, a supply shortage detection signal indicating that there is no game ball to be paid out, and a counting switch detection signal indicating that the game ball has been paid out are included.

Next, the launch relay board 26 supplies a drive signal received from the launch control circuit element SH to the ball feed solenoid SLf, and realizes a launch control operation together with the launch solenoid SLe. Further, on the launch relay board 26, regarding the launch handle 10 operated by the player, a launch stop switch STOP for instructing the launch stop of the game ball, a touch sensor TCH indicating that the player is touching the launch handle 10, and a touch sensor TCH indicating that the player is touching the launch handle 10. , The signal from the firing intensity volume VR indicating the rotation position of the firing handle 10 is received, and each received signal is transferred to the one-chip microcomputer MCOM4 of the payout control board 24.

FIG. 6 illustrates the solid ground surface of the payout control board 24, and schematically shows the upper left corner portion on the surface side of the payout control board 24. As described above, the solid earth surfaces formed on the front and back surfaces of the payout control board 24 are separated by an isolation line and divided into a first ground surface A_GND and a second ground surface D_GND shown by shading in FIG. ing. The solid line that determines the boundary between the shaded area and the other blank area is the isolation line. Although FIG. 6 shows the front surface side of the payout control board 24, the area corresponding to the shaded portion on the front surface side is also the first ground surface A_GND on the back surface side.

In FIG. 6, the first connector CN1 that receives three types of DC voltages (35V, 12V, 5V) from the power supply board and the second connector CN2 that drives the ball feed solenoid SLf and receives various signals for launch control. A third connector CN3 for driving the firing solenoid SLe, a firing control circuit element SH, a stabilized power supply circuit REG, and the like are described. The connection point to the first ground surface A_GND and the connection point to the second ground surface D_GND are represented by different earth symbols for convenience.

Here, the ground terminal GND of the second connector CN2 is connected to the second ground surface D_GND, and all the other connector terminals are connected to the lead terminals of the emission control circuit element SH via the signal pattern of the circuit board. Has been done. The lead terminals of the emission control circuit element SH are connected to the first power supply terminals T1 and T2 to which the DC voltage 35V is distributed, the second power supply terminals T9 to which the DC voltage 5V is distributed, and the first ground surface A_GND. There is a first ground terminal T7 and a second grant terminal T14 connected to the second ground surface D_GND. As shown in the figure, 5V output by the regulated power supply circuit REG is distributed to the second power supply terminal T9.

Further, as shown in FIG. 6, an electrolytic capacitor C1 is arranged between the power supply line having a DC voltage of 35 V and the first ground surface A_GND. Then, this DC voltage 35V is directly supplied to the first power supply terminals T1 and T2 of the emission control circuit element SH, and is also supplied to the lead terminal T3 of the emission control circuit element SH via the current limiting resistor RS. (See FIG. 8). Further, the signal from the touch sensor TCH is transmitted to the lead terminal T8 of the emission control circuit element SH and is connected to the first ground surface A_GND via the surge absorber SA (see FIG. 8).

The surge absorber SA is an element that normally maintains a high resistance value and hardly allows current to flow, but changes to a low resistance when it receives a surge voltage (abnormal voltage). Then, when a player charged with high static electricity touches the firing handle 10, the surge voltage is absorbed from the touch sensor TCH via the surge absorber SA to the first ground surface A_GND, so that the firing control circuit element Destruction and deterioration of SH are prevented. Since the surge current due to the charged static electricity does not flow into the second ground surface D_GND, there is no risk of the computer circuit malfunctioning.

The upper left corner portion on the front surface side of the payout control board 24 has the above circuit configuration. Then, as can be confirmed by the shaded portion in FIG. 6, the isolation line is formed so as to divide the first connector CN1, the second connector CN2, and the launch control circuit element SH into two, respectively. That is, in the first connector CN1, the first power supply terminal to which the DC voltage 35V is distributed and the corresponding grant terminal are located above the first ground surface A_GND, and the remaining terminals are the second ground surface D_GND. It is located at the top of.

Further, in the second connector CN2, only the drive terminal pair that transmits the drive signal to the ball feed solenoid SLf is located above the first ground surface A_GND, and the remaining terminals are located above the second ground surface D_GND. .. The third connector CN2 is located above the first ground surface A_GND.

On the other hand, the launch control circuit element SH is a first drive terminal pair T5, T6 that outputs a drive signal to the launch solenoid SLe, a drive terminal pair T3, T4 that outputs a drive signal to the ball feed solenoid SLf, and a first DC voltage of 35 V. The power supply terminals T1 and T2 and the ground terminal T7 connected to the first ground surface A_GND are located above the first ground surface A_GND, and the remaining terminals are located above the second ground surface D_GND. ..

Therefore, even if the launch control circuit element SH, the first to third connectors CN2, and other circuit components are mounted through holes, the ground wiring can be appropriately completed. In addition, the power supply pattern and signal pattern corresponding to the first ground surface A_GND are not complicated.

Next, FIG. 7A is a block diagram showing an internal configuration of the launch control circuit element SH. As shown in the figure, the launch control circuit element SH has a built-in AND circuit that receives the energization signal POUT, the logically inverted launch permission signal SHOOT, the logically inverted stop switch signal STOP, and the touch sensor signal TCH. ing.

Further, the emission control circuit element SH outputs a current corresponding to the voltage level of the signal passing through the negative feedback amplifier AMP, the energization cutoff unit CUT that cuts off or passes the output of the negative feedback amplifier AMP, and the energization cutoff unit CUT. The current amplification transistor Tr2 is built-in. The negative feedback amplifier AMP operates by receiving the output of the emission intensity signal VR and the current detection resistor Rr, and the current amplification transistor Tr2 is configured to output the current corresponding to the emission intensity signal VR.

The launch control circuit element SH includes an oscillator OSC, a frequency divider DV that divides the output of the oscillator OSC so that the frequency matches the firing operation of the game ball, and a clock pulse CK output by the frequency divider DV. It has a built-in octadecimal counter CT that counts. FIG. 9 shows the relationship between the clock pulse CK, the CE clock (denoted as CE bar) which is an inverted signal thereof, and the outputs Q0 to Q7 of the counter CT. As shown in the figure, the outputs Q0 to Q7 of the counter CT change according to the cumulative number of CE clocks after the clear signal CLR changes to inactive (L).

Although not limited in any way, in the case of the embodiment, the cycle of the CE bar signal is set to about 75 mS, and the duty ratio is set to 50%. Therefore, the period of the outputs Q0 to Q7 of the octadecimal counter is about 8 × 75 = 600 mS. Further, as shown in FIG. 10, the firing cycle and the ball feeding cycle are also about 600 mS, and about 100 game balls can be launched per minute.

The outputs Q0 to Q7 of the counter CT are supplied to the energization cutoff unit CUT, the energization control transistor Tr1 and the energization control switch SW via an appropriate logic circuit. The energization control transistor Tr1 receives the Q1 * CE bar signal and operates ON, and outputs DC 35V to the ball feed solenoid SLf. Further, the energization control switch SW receives the Q1 + Q2 signal and operates ON to receive the feedback current from the ball feed solenoid SLf. In the above operation, the "*" symbol means a logical product, the "+" symbol means a logical sum, and the following description is the same.

On the other hand, the energization cutoff unit CUT operates by receiving the Q2 * CE bar signal, passes the output of the negative feedback amplifier AMP only at the timing when the Q2 * CE bar signal is H level, and cuts off the energization at other timings. By turning on the CUT, the output of the negative feedback amplifier AMP is short-circuited to the second ground surface D_GND.

Further, when the connection with the ball lending machine LEN is established, the energization signal becomes POUT = H, if the main control unit 21 permits firing, the firing permission signal becomes SHOOT = H, and if the stop switch is not operated, the stop switch signal is displayed. STOP = H, and when the player touches the firing handle 10, the touch sensor signal is configured to be TCH = L.

Therefore, when evaluated at each logic level of the lead terminals T12, T13, T10, and T9 of the launch control circuit element SH, when POUT = H, SHOOT = L, STOP = L, and TCH = L are established, the ball feed solenoid SLf is set. The firing operation by the firing solenoid SLe is permitted.

Next, FIG. 7B illustrates the internal configuration of the touch sensor. When the player holds the firing handle 10, the sense transistor Qs is in the ON state, and the touch sensor signal TCH = L. It becomes. Then, when evaluated at the logic level of the signal supply source, the output of the AND circuit is H under the conditions of energization signal POUT = H, emission permission signal SHOOT = H, stop switch signal STOP = H, and touch sensor signal TCH = L. The level is reached, the frequency dividing operation of the frequency divider DV is permitted, and the game ball is intermittently launched in a legal predetermined cycle (about 600 mS in the embodiment) determined by the frequency of the output signal.

On the other hand, if any of the above conditions is not satisfied, the game ball will not be fired. The firing operation of the game ball is realized by intermittently energizing the firing solenoid SLe, but the firing intensity corresponds to the energizing current of the firing solenoid SLe defined based on the value of the firing intensity volume VR. Be controlled. Further, the ball feed solenoid SLf is energized in accordance with the firing cycle, and the firing ball is set at a predetermined firing position.

FIG. 8 is a circuit diagram showing an output unit of the launch control circuit element SH that realizes the above operation, and FIG. 10 is a time chart illustrating the operation of the launch control circuit element SH.

As shown in the figure, the output unit of the launch control circuit element SH is mainly composed of an energization control transistor Tr1 that supplies a drive current to the ball feed solenoid SLf and a current amplification transistor Tr2 that supplies a drive current to the launch solenoid SLe. ing. Further, the launch control circuit element SH has a damper that absorbs the counter electromotive force generated at the timing Ti2 of FIG. 10 in which the drive current of the ball feed solenoid SLf suddenly decreases and the timing Ti3 of FIG. 10 in which the drive current of the launch solenoid SLe is interrupted. The diodes D1 and D2 are built-in.

First, the energization control transistor Tr1 will be described. As shown in FIG. 8, the energization control transistor Tr1 operates ON / OFF based on the ON / OFF operation of the control transistor Tr3 that receives the Q1 * CE bar signal. Here, the Q1 * CE bar signal is as shown in FIG. 10 (f), becomes the H level only during the period of timing Ti1 to Ti2, and maintains the L level at other timings.

Therefore, the control transistor Tr3 operates ON only during the period of timing Ti1 to Ti2, and a current flows in the path of the power supply voltage 35V → resistor R4 → resistor R3 → second ground. As a result, the energization control transistor Tr1 composed of the P-channel MOS operates ON based on the voltage across the bias resistor R4.

On the other hand, the energization control switch SW receives the Q1 + Q2 signals shown in FIG. 10 (e) and operates ON / OFF, and is in the ON operation state during the periods of timings Ti1 to Ti3. Therefore, the ON current flowing from the source terminal S of the energization control transistor Tr1 in the ON operation state to the drain terminal D flows into the ground terminal of the energization control switch SW via the ball feed solenoid SLf.

Then, the ball feed solenoid (electromagnetic solenoid) SLf operates to operate the electromagnet, and a part of the ball feed member (not shown) is attracted to the electromagnet, so that the head position of the series of game balls is reached. Is accepted in the standby position (see FIG. 10 (i)). Note that FIG. 10 (i) illustrates the potential V1 of the lead terminal T4 of the emission control circuit element SH, which is zero at this timing Ti1. Further, in the acceptance timing Ti1, the game ball in the standby position is moved to the launch position at the launch position located on the downstream side of the standby position when the preceding ball feed solenoid SLf is turned off.

By the way, as shown in FIG. 8, the emitter terminal of the control transistor Tr3 is connected to the second ground surface D_GND, and the ground terminal of the energization control switch SW is connected to the first ground surface A_GND. Here, the first ground surface A_GND and the second ground surface D_GND are electrically separated by the payout control board 24, but the potentials of the two ground surfaces A_GND and D_GND are the COM terminals of the power supply board 20 (FIG. Since it is standardized in 5), the above operation is not hindered.

The operation of the timing Ti1 to Ti2 has been described above, but after the timing Ti2, the Q1 * CE bar signal becomes the L level (see FIG. 10 (f)), and the current of the resistor R4 is interrupted, so that the control transistor Tr3 becomes , OFF state. However, the energization control switch SW that receives the Q1 + Q2 signal and operates ON / OFF maintains the ON state during the timings Ti1 to Ti3. Further, in the case of this embodiment, the current limiting resistor RS is arranged between the terminals T1 and T2 of the emission control circuit element SH.

Therefore, between the timings Ti2 and Ti3, the drive current continues to flow in the path of the power supply voltage 35V → current limiting resistor RS → ball feed solenoid SLf → energization control switch SW → first ground. However, this drive current has a suppression level limited by, for example, a current limiting resistor RS of about 270Ω.

The current value of this suppression level is appropriately set, but since a part of the ball feed member is already attracted to the electromagnet by the ON operation of the ball feed solenoid SLf at the timings Ti1 to Ti2, this suction state is set. The current that can be maintained is sufficient. That is, a certain amount of suction torque (starting torque) is required to suck the ball feed member in the separated state, but not so much torque is required to maintain the suction state, and driving at an appropriate suppression level. Current is enough.

Specifically, in this embodiment, the starting torque section of Ti1 to Ti2 carries a starting torque current of, for example, about 490 mA, whereas the holding torque period of Ti2 to Ti3 is a holding current of about 100 mA. Designed to flow. According to the study of the present inventor, the holding current should be at least less than 1/2 of the starting torque current, preferably 1/3 or less, and more preferably 1 / 4.5 to 1 /. We have confirmed that it should be 5.5. In addition, in this specification, a symbol "~" includes both ends of a numerical range.

In any case, in this embodiment, after the suction operation is realized by the starting torque current, the drive current is suppressed, so that wasteful power consumption can be avoided and wasteful heat generation can be prevented, and the ball feed solenoid SLf It is possible to prevent thermal damage and deterioration. Further, in this embodiment in which the operation timings of the ball feed solenoid SLf (Ti1 to Ti3) and the operation timings of the launch solenoid SLe partially overlap, a large current does not flow through the ball feed solenoid SLf at the launch timing, so that the power supply is supplied. The voltage drop of the line is suppressed, and the drive voltage supplied to the firing solenoid SLe ensures that the design value is maintained.

More specifically, in relation to each of the above effects, first, in this embodiment, the current effective value is set by providing a starting torque section having a current value of 490 mA and a holding torque period having a current value of 100 mA. The power consumption is reduced by suppressing it to about 141 mA. It has also been confirmed that the starting torque section should be 35 mS to 55 mS in the measured value affected by the inductance of the ball feed solenoid SLf in order to suppress power consumption and ensure the ball feed operation. The section ratio between the starting torque section and the holding torque period is preferably in the range of 1: 1.5 to 1: 3.5 in the measured value affected by the inductance of the ball feed solenoid SLf, and the inductance is ignored. As shown in FIG. 10, it is preferable that the design value is 1: 3.

A large counter electromotive force is generated at the timing Ti2 in FIG. 10 in which the drive current of the ball feed solenoid SLf suddenly decreases (to 1 / 4.9 in the embodiment), and this counter electromotive force is applied to the damper diode D1. Since it is absorbed, there is no possibility that the energization control transistor Tr1 will be damaged.

By the way, when the damper diode D1 is not provided, the potential of the source terminal S of the energization control transistor Tr1 is + 35V at the timing Ti2, whereas the energization control switch SW is ON at the drain terminal D. Since a large reverse voltage in the negative direction is applied, an excessive voltage may be applied between the source terminal S and the drain terminal D (between SD) of the energization control transistor Tr1. This point is the same for the damper diode D2 in the sense that it absorbs the excessive voltage between the SDs of the current amplification transistor Tr2.

Subsequently, the operation of the current amplification transistor Tr2 will be described. At the bottom of FIG. 8, the energization cutoff section CUT that allows / prohibits the passage of the current control signal SG corresponding to the emission intensity volume VR, and the preposition that linearly operates in response to the current control signal SG that has passed through the energization cutoff section CUT. The transistor Tr4 and the current amplification transistor Tr2 that supplies the current corresponding to the linear operation of the front transistor Tr4 to the firing solenoid SLe are described.

The energization cutoff unit CUT operates in response to the Q2 * CE bar signal shown in FIG. 10 (d), operates ON when the Q2 * CE bar signal is normally at the L level, and short-circuits the input signal SG to ground. By making it, the transmission of the current control signal SG is prohibited. On the other hand, when the Q2 * CE bar signal changes to the H level, the energization cutoff unit CUT transitions from the ON state to the OFF state, and the short circuit of the current control signal SG to the ground is released, so that the current control signal at a significant level is released. SG is transmitted to the front transistor Tr4.

Here, the level of the current control signal SG corresponds to the emission intensity volume VR, and the current corresponding to the current control signal SG corresponds to the DC voltage 35V → bias resistance R8 → collector resistance R7 → front transistor Tr4 → second. It flows along the ground route. Then, a voltage across the bias resistor R8 is applied between the source terminal S and the gate terminal G of the current amplification transistor Tr2 composed of the P-channel MOS, so that a predetermined level of drive current is applied from the drain terminal D of the current amplification transistor Tr2. Will be output.

This drive current flows in the path of the power supply voltage 35V → the current amplification transistor Tr2 → the firing solenoid SLe → the current detection resistor Rr → the first ground. Note that FIG. 10H illustrates the potential V2 (= Vr) of the lead terminal T6 of the emission control circuit element SH, and the voltage Vr across the current detection resistor Rr is fed back to the negative feedback amplifier AMP. As a result, the drive current is maintained at a predetermined level corresponding to the emission intensity signal VR.

Then, the firing solenoid SLe functions in response to this drive current, so that the game ball at the firing position is hit with a predetermined firing torque and fired. In this way, the firing torque is defined by the level of the drive current supplied to the firing solenoid SLe, but in this embodiment, (1) by exclusively generating a power supply voltage of 35V for driving the solenoid, other Distinguish from the power supply voltage of 12V and 5V, (2) lower the impedance of the power supply line and ground line from the power supply board 20 to the payout control board 24, and (3) isolate the first ground surface A_GND from the second ground surface D_GND. In addition, (4) since the drive current of the ball feed solenoid SLf is suppressed prior to the launch timing, the drive current to the launch solenoid SLe does not fluctuate.

For example, if the potential difference between the power supply line with a power supply voltage of 35 V and its ground line fluctuates, the feedback path cannot immediately follow the fluctuation of the potential difference, no matter how negative feedback control is performed (predetermined response). (Time is required), the drive current of the firing solenoid SLe may not be constant, and the arrival position of the game ball may not be constant.

Further, in this embodiment, the drive current of the ball feed solenoid SLf is suppressed prior to the launch timing, but if this measure is not taken, the power supply line corresponding to the drive current to the ball feed solenoid SLf or Accurate firing operation may not be maintained due to the ground line voltage drop. That is, since the drive current of the ball feed solenoid SLf is not controlled by a constant current, the drive current changes in response to heat generation of the circuit element and the ball feed solenoid SLf, and the power supply line has a power supply voltage of 35 V. , The potential difference from the ground line may promote wobbling.

Although the examples in which accurate firing operation can be realized have been described in detail above, the specific description contents are not particularly limited to the present invention and can be appropriately changed. For example, in the above embodiment, the driving current is supplied to the firing solenoid SLf (Ti1 to Ti3) to move the game ball to the standby position, and then the driving current of the firing solenoid SLf is stopped to obtain the standby position. The game ball was moved to the launch position, but there is no limitation.

That is, as shown in FIG. 11, a drive current is supplied to the ball feed solenoid SLf to move only the game ball at the head position to the launch position (period (a)), and then the drive current to the ball feed solenoid SLf. In the state where is stopped (period (b)), the movement of the game ball may be stopped.

In FIG. 11, the firing solenoid SLe is turned on while the drive current to the ball feed solenoid SLf is stopped, but the method is not limited and the ball is the same as in FIGS. 10 (h) and 10 (i). The firing solenoid SLe may be activated at the end when the feed solenoid SLf is energized.

By the way, in the above embodiment, the bullet game machine that actually pays out the game ball to the player has been described, but the management game machine (so-called enclosed game machine) that does not involve the prize ball operation to the player can also be used. The present invention is suitably applicable. In the enclosed game machine, the actual prize ball operation is avoided by storing the game value corresponding to the prize ball to the player in the IC card or the like (adding the game value).
