  FIG. 1 shows a payout mechanism 302 of a sphere (here, a pachinko sphere) 300 according to the present embodiment and a control block diagram thereof.

  The payout mechanism unit 302 includes a winning detection switch 308 that individually detects a pachinko ball 300 that has won a plurality of winning holes 306 in a pachinko gaming machine 304 (see FIG. 2). These winning detection switches 308 are connected to the winning ball calculation unit 312 of the winning ball control device 310. In the winning ball calculation unit 312, the number of payouts for each winning detection switch 308 is determined. For example, 10 payouts are awarded for a given winning opening 306, 15 payouts are awarded for another winning entry 306, and so on.

  The winning ball calculation unit 312 is connected to the winning ball payout remaining number counting unit 314 and sends the calculation result to the winning ball payout remaining number counting unit 314. The winning ball payout remaining number counting unit 314 adds the number of balls sent and stores the added value in the memory 316.

  The prize ball payout remaining number counting section 314 is connected to a prize ball payout instructing section 318. When the prize ball payout remaining number count value (that is, the remaining payout number) is other than 0, this prize ball payout instruction A payout request is made to the section 318.

  Based on this pulse signal, the prize ball payout instructing unit 318 sends a payout signal (H or L binary signal) to the prize ball solenoid controller 322 that controls the prize ball solenoid 320 constituting a part of the payout mechanism 302. It is supposed to be sent out. The high level (H) signal is a payout signal, and the low level (L) signal is a payout stop signal.

  In the prize ball solenoid controller 322, the prize ball solenoid 320 is excited when the signal input to the prize ball solenoid controller 322 is at a high level, and the prize ball solenoid 320 is not energized when the signal is at a low level. Control.

  The prize ball solenoid 320 is disposed in the vicinity of a cylindrical payout ball guide path 324. The upper part (not shown) of the payout ball guide path 324 is provided with a hopper portion of the pachinko ball 300, and the lower part (not shown) is opened toward the player's tray.

  A slit-like through hole 326 is provided on the side surface (circumferential surface) on which the prize ball solenoid 320 is disposed.

  The prize ball solenoid 320 includes a rod 320A that contracts when excited.

  The stopper member 330 has a substantially triangular shape, and a circular hole 332 is provided in the vicinity of the apex 330 </ b> A and is inserted into the shaft 334. As a result, the stopper member 330 can rotate around the shaft 334. Further, the other vertex (the vertex at the right end of the base shown in FIG. 1) 330B corresponds to the slit-like through hole 326 of the payout ball guide path 324, and this vertex is obtained by rotation about the shaft 334. The vicinity of 330B appears and disappears in the through hole 326.

  Furthermore, a circular hole 336 is also provided in the vicinity of another vertex (vertical leftmost vertex shown in FIG. 1) 330C, and a shaft 338 attached to the tip of the rod 320A of the prize ball solenoid 320 is pivotally supported. . One end of a tension coil spring 340 is attached to the shaft 338, and the other end is fixed to a base plate (not shown).

  As a result, the rod 320 </ b> A is extended by the biasing force of the tension coil spring 340 while the prize ball solenoid 320 is not excited.

  The stopper member 330 rotates about the shaft 334 according to the expansion and contraction of the rod 320A. Therefore, when the prize ball solenoid 320 is not excited, the stopper member 330 is counteracted in FIG. Rotating clockwise, the vicinity of the apex 330B enters the slit-like through-hole 326 and closes the discharge passage.

  On the other hand, in the excited state of the prize ball solenoid 320, the rod 320A is drawn by the magnetic force, whereby the stopper member 330 rotates in the clockwise direction in FIG. 1, and the vicinity of the apex 330B comes out of the through hole 326 and passes through the payout passage. Open.

  Wherein immediately below the through hole 326, ring-shaped payout completion ball detection switch 342 so as to surround the dispensing ball guideway 324 is provided.

  In the payout completion ball detection switch 342, it passes through the stopper member 330 is a sensor for detecting the pachinko ball reliably reach the original player. Detection signals by the payout completion ball detection switch 342 is adapted to be sent to prize balls paid out balls registration unit 344 of the winning balls controller 310. The winning ball payout ball registration unit 344 sends a pulse signal each time the paid ball detection switch 342 detects that the pachinko ball 300 has been paid out to the prize ball payout remaining number counting unit 314. . The prize ball payout remaining number counting unit 314 subtracts the remaining number by one from one pulse sent from the prize ball payout ball registration unit 344. The subtraction method is not limited to the pulse signal count (addition count, subtraction count), and various other known methods may be used as long as the dispensed ball is reliably subtracted.

  As a result, the winning ball payout remaining number counting unit 314 adds the remaining number every time a winning is made, and subtracts the remaining number every time the paying is made. Can be paid out in numbers.

  Here, in the present embodiment, a backup unit 346 that holds a voltage equivalent to the operating power supply voltage supplied as a whole of the prize ball control device 310 is connected to the prize ball payout remaining number counting unit 314. The backup unit 346 has a charging function capable of storing electric charge in a normal state. When a power interruption occurs, the backup unit 346 stores the prize ball payout remaining number counting unit 314 in the memory with the power supply voltage from the backup unit 346. The recorded payout remaining number can be stored and held. That is, after the power is restored, the operation is performed from the state immediately before the power is turned off, and the player is prevented from suffering a disadvantage due to the elimination of the payout remaining due to the power being turned off.

  In the present embodiment, the energization of the prize ball solenoid 320 is stopped first during a period from the start of voltage drop immediately after the power is turned off until the prize ball control device 310 can be operated, and after a predetermined time has elapsed, A delay time for stopping the operation of the prize ball control device 310 is provided. This is to maintain the accuracy of the payout remaining number, and to detect the pachinko ball 300 to be finally paid out by the operation of the stopper member 330.

  The operation of this embodiment will be described below.

  The winning detection switch 308 detects a winning ball when a pachinko ball 300 launched from a launching device (not shown) wins a winning opening 306, and the winning ball calculation unit 312 sets in advance a corresponding to the winning detection switch 308. Converted to the number of paid-out balls, a signal corresponding to the number of paid-out balls is sent to the prize ball payout remaining number counting unit 314.

  The prize ball payout remaining number counting unit 314 always stores the payout remaining number in the memory 316, reads the remaining number, adds the payout ball number, and stores it.

  When there is a remaining number of payout balls stored in the winning ball payout remaining number counting unit 314 (that is, other than 0), a payout instruction signal (high) is sent from the prize ball paying instructing unit 318 to the prize ball solenoid controller 322. Level signal) is transmitted. In response to the high level signal, the prize ball solenoid controller 322 brings the prize ball solenoid 320 into an excited state.

  When the prize ball solenoid 320 is excited, the rod 320A is drawn, and the stopper member 330 rotates about the shaft 334 in the clockwise direction in FIG. With this rotation, the vicinity of the apex 330B of the stopper member 330 is retracted from the through-hole 326 of the payout ball guide path 324 and the passage is opened, so that the pachinko ball 300 flows to the player's tray. Basically, the pachinko ball 300 is continuously dispensed while the high-level instruction signal is being output, but the stopper member 330 is retracted while the high-level instruction signal is being continuously output. Then, pachinko balls are paid out continuously.

  The pachinko ball 300 that has passed through the closed portion by the stopper member 330 is detected by the winning ball paid-out ball detection switch 342, and the signal is sent to the winning ball payout registration unit 344.

  The prize ball payout registration unit 344 sends a pulse signal each time the pachinko ball 300 is paid out to the prize ball payout remaining number counting unit 314. In prize balls paid out remaining number counting unit 314 subtracts the number of remaining one for one pulse of the signal sent from the prize balls paid out balls registration unit 344.

  As a result of this subtraction, when there is no payout remaining number stored in the prize ball payout remaining number counting unit 314 (that is, 0), the instruction signal becomes low level, and the prize ball solenoid controller 322 de-energizes the prize ball solenoid 320. State. Therefore, the rod 320A is extended by the urging force of the tension coil spring 340, and the stopper member 330 rotates about the shaft 334 in the counterclockwise direction in FIG.

  As a result, the vertex 330B enters the through hole 326, closes the payout ball guide path 324, and stops the pachinko ball 300 from flowing out.

  By repeating the above, each time the prize to the winning port 306, it is possible to pay out pachinko ball 300 to the player at the proper payout.

  If a sudden power interruption such as a power outage (hereinafter simply referred to as a power outage) occurs during the normal game, the power supply does not spread to each part and the operation of the prize ball solenoid 320 stops (de-energized state) Then, the operation of the prize ball control device 310 is also stopped. For this reason, the remaining payout amount that has been stored will also be erased, which is disadvantageous to the player.

  Therefore, in the present embodiment, backup power is supplied from the backup unit 346 to the winning ball payout remaining number counting unit 314 in order to maintain the necessary minimum voltage and eliminate the disadvantage of the player. The details of the processing at the time of power failure will be described below with reference to the flowchart of FIG.

  First, in step S600, the power to the prize ball solenoid 320 is turned off first. This is equivalent to the instruction signal being at a low level, the prize ball solenoid 320 is in a non-excited state, and the payout ball guide path 324 is closed by the stopper member 330. Note that this closed state is held by the biasing force of the tension coil spring 340. Thereby, the prize ball payout is stopped.

  Next, in steps S602, 604, and 606, detection of the payout ball is continued for a predetermined time. This is to accurately detect the pachinko ball 300 to be paid out last, based on the relationship between the operation of the prize ball solenoid 320 and the position of the pachinko ball 300 to be paid out, and even after the energization of the prize ball solenoid 320 is cut off. The above-described accurate detection can be performed by operating the winning ball paid-off ball detection switch 342 and the winning ball control device 310 normally.

  If it is determined in step S606 that the predetermined time has elapsed, the process proceeds to step S608, and the final payout remaining number is stored in the memory. Since the memory is always secured by the backup power source from the backup unit 346, the payout remaining number storage data can be securely stored.

  After storing the payout remaining number, the process waits for reset. In other words, the above control is performed while the voltage drop immediately after a power failure is maintained while the prize ball control device 310 or the like maintains an operable voltage, and the voltage naturally decreases with time. Then, finally, the power supply voltage becomes zero. However, as described above, only the remaining payout number can be held for a sufficient time by the backup power source.

  After the power is restored, a reset is applied, and the prize ball control device 310 starts up in the same manner as when the power is turned on normally. That is, since it is not known when a power failure occurs, a reset is applied to reliably start the main program of the prize ball control device 310. As a result, the program is prevented from running out of control, and the prize ball control device 310 is reliably restored.

  After the return, the process starts from reading out the remaining payout stored in the winning ball payout remaining counting section 314. If there is a remaining, it is executed immediately after the power is restored to win before the power failure and payout. Pachinko balls 300 that have not been played can be paid out to the player accurately. In addition, even if the player starts playing and wins after the power is restored, since it is added to the stored remaining payout number, the system according to the present embodiment also gives the player a problem caused by a power failure. I will never give it to a pachinko parlor.

  In this embodiment, the prize ball solenoid 320 is used as a part of the payout mechanism 302. However, as a mechanism for operating the stopper member 330, other driving sources such as a stepping motor and an electromagnetic clutch may be applied. Good. In any case, any structure may be used as long as the payout ball guide path 324 is closed in a power-off state.

  PDWN as a power-off detection signal is input to the NMI terminal of the IC 138. This NMI is a non-maskable external interrupt terminal provided in the CPU 140. When the signal at this terminal becomes active, the CPU 140 executes an NMI interrupt process stored in the ROM 144. An INT terminal can also be applied to this NMI. That, INT is a maskable external interrupt pin, this pin is active CPU140 executes the INT interrupt process is stored in the ROM 144.

  Here, NMI with high urgency of processing is applied, and when a power failure occurs, this is detected and has a role of notifying the IC 138 of the payout control board 16 of the occurrence of the power failure. By receiving this notification, the IC 138 executes NMI interrupt processing (predetermined power-off processing).

  Also, VBACKUP as a backup power source is connected to the RAM 142 of the IC 138. This VBACKUP has a role of supplying backup power to the RAM 142 of the IC 138. The voltage of the backup power supply is such that the data stored in the RAM 142 can be stored and maintained for a predetermined time (about 4.5V) and capacity. Has been.

  Further, the communication line 120 from the prepaid card unit 36 is input to the IC 138 via the input / output port 122.

  The IC 138 is further connected with three input ports 160, 162, and 164 and three output ports 166, 168, and 170.

  The first input port 160 is connected to an input buffer 84 to which a command sent from the output buffer 78 of the main control board 14 is input.

  A photocoupler 188 having the same configuration as that of the photodiode 88 is connected to the second input port 162 (configuration description is omitted). The photocoupler 188 is connected to the power branch line 90A from the main control board 14 and the signal branch line 90B from the prize ball paid-out ball detection switch 86C, which are branched by the prize ball relay board 90, and the prize ball is paid out. A signal from the finished ball detection switch 86 is inputted.

The third input port 164 is connected to a signal line 180A from a lending ball detection switch 180 provided in the lending / dispensing device 178 so that a predetermined signal is inputted. The lending ball detection switch 180 operates with a power supply voltage of DC12V-B (see the power supply line 180B and the ground line 180C).
The first output port 166 is connected via an output driver 182 to an operation signal line 86G of a prize ball solenoid 86E provided in the prize ball payout device 86. The power line 86F of the prize ball solenoid 86E receives a power supply voltage of DC12V-A from the payout control board 16. The prize ball solenoid 86E discharges pachinko balls by excitation and has a role of opening and closing a stopper member that stops the flow of pachinko balls by non-excitation (see the embodiment), and the first output port The opening / closing of the stopper member is controlled in accordance with a signal from 166.

  The second output port 168 is connected to the lending solenoid 192 provided in the lending dispensing device 178 via output drivers 184. The rental solenoid 192 operates with a power supply voltage of DC12V-A. The lending solenoid 192 is configured to be equivalent to the prize ball solenoid 86E in order to lend the number of balls according to money (including prepaid cards), and discharges pachinko balls by excitation and flows of pachinko balls by non-excitation. The stopper member opens and closes the stopper member, and the opening and closing of the stopper member is controlled in accordance with a signal from the second output port 168.

The third output port 170 is connected to the launch control board 24 via the output buffer 194, and permits and prohibits signals relating to launch (operation of the device for launching the pachinko ball (launch solenoid 34)) are dispensed control boards. 16 is sent out. The launch control board 24 is supplied with a predetermined power supply voltage from the relay board 26.
(Configuration of power supply board)
As shown in FIG. 5, the casing (not shown) of the power supply board 12 has terminals 204A and 204B to which power lines 202A and 202B are connected from a power plug 200 to which a commercial power supply AC24V (50/60 Hz) is input. A terminal 204C for grounding the casing of the power supply board 12 is provided. The commercial power supply is normally 100 V / 50 Hz or 100 V / 60 Hz, but is stepped down to 24 V by a transformer or the like provided on the island side (not shown). A surge absorber 205 is connected to the terminal 204C. The surge absorber 205 is for discharging the electric charges of the ground to the frame ground when the ground level of the power supply substrate 12 becomes somewhat larger than the frame ground. Thereby, frequent fluctuations in the ground level can be suppressed, and noise resistance against static electricity and the like can be improved.

  The terminals 204A and 204B are connected to the terminals 204D and 204E by connection lines 206 and 207, and the prepaid card unit 36 is connected to the terminals 204D and 204E. A fuse 208 is interposed on the connection line 206 side.

  The power supply lines 202A and 202B connected to the terminals 204A and 204B are respectively connected to the full-wave rectifier circuit 210 (the overcurrent protection circuit 209 is interposed in the power supply line 202A).

Overcurrent protection circuit 209 is provided for the purpose of protecting the power supply board 12 from the overcurrent.

  The full-wave rectifier circuit 210 is configured by a bridge circuit including four diodes, and an AC power source is converted to a DC power source. Therefore, the output of the full wave rectifier circuit 210 is the power line 212 and the ground line 214.

  The power supply line 212 is divided, and one is connected to a terminal 204F (DC24VRMS) via an overcurrent protection circuit 218. The purpose of this overcurrent protection circuit 218 is to protect the lamp control board 22, the launch control board 24, or the electronic components from overcurrent.

  The other of the power supply line 212 is connected to a DC12V-A regulator 222, a DC12V-B regulator 223, a DC5V regulator 224, and a first power-off detection circuit 226 via a smoothing circuit 220 composed of a diode and an electrolytic capacitor. Are input to the second power-off detection circuit 227, respectively. The DC12V-A regulator 222, the DC12V-B regulator 223, and the DC5V regulator 224 each include an overcurrent protection circuit.

  The output terminal of the DC12V-A regulator 222 is connected to the terminal 204G (DC12V-A), the output terminal of the DC12V-B regulator 223 is connected to the terminal 204H (DC12V-B), and the output terminal of the DC5V regulator 224 is the terminal 204I. (DC5V) is connected.

  The first power-off detection circuit 226 is a circuit that outputs a low level signal when the input voltage drops to a predetermined value V1, and is input to the DC12V-A regulator 222 as an output stop signal.

  The second power-off detection circuit 227 is a circuit that outputs a low level signal when the input voltage drops to a predetermined value V2 (V2 <V1), and is connected to the terminal 204J (PDWN). Further, the output line of the second power interruption detection circuit 227 is branched and connected to the input side of the delay circuit 229. The output side of the delay circuit 229 is input to the DC5V regulator 224 as an output stop signal.

  The DC5V regulator 224 is branched at the output end, and is connected to one end of an electric double layer capacitor 230 applied as a backup power source via a Schottky diode 228. An electrolytic capacitor may be used instead of the electric double layer capacitor 230 as long as it functions as a power storage capacitor.

  The Schottky diode 228 is provided in order to supply current from the DC5V power supply to the electric double layer capacitor 230 when the 5V power supply recovers, and to prevent the current from flowing back from the electric double layer capacitor 230 to the DC5V terminal when the 5V power supply is cut off. It is.

  The other end of the electric double layer capacitor 230 is grounded. One end side of the electric double layer capacitor 230, that is, the plus side is connected to the terminal 204K (VBACKUP). Note that the terminal 204L (GND) is grounded.

  Further, a discharge resistor 232 is connected to the terminal 204K and grounded. This is provided to discharge the electric charge stored in the electric double layer capacitor 230. In other words, since the holding current of the RAM 142 is generally small and the variation is large, it is difficult to calculate the backup time. Therefore, by setting the discharge resistor 232 so that the large discharge current negligible holding current of RAM 142, to facilitate the calculation of the backup time. As indicated by a two-dot chain line in FIG. 5, a circuit in which a discharge resistor 234 and a switch 236 are connected in series is arranged in parallel with the discharge resistor 232, and the switch 236 is turned on when it is desired to forcibly cancel the backup. However, the discharge resistor 234 may discharge quickly. In addition, since the discharge resistor 234 is used for the purpose of forcibly releasing the backup, it is necessary to set the resistance value so that the discharge current value becomes large. Note that the discharge may be performed only by the switch 236 without using the discharge resistor 234.

  The DC12V-A regulator 222 generates stabilized DC12V from the direct current power input from the smoothing circuit 220. This output power supply is used as a power supply for high-power electronic components that generally consume a large amount of power other than switches such as prize ball solenoids.

  Further, the DC12V-A regulator 222, the output stop signal from the first power supply interruption detecting circuit 226, forcibly output is adapted to be stopped.

  This is for maintaining the other power supply systems (DC12V-B and DC5V) for a long time by immediately stopping the output of the power supply system with large power consumption when the power is cut off. As a result, the smoothing circuit 220 can be made small in size.

  In addition, the power supply used as the prize ball solenoid power supply is stopped immediately when the power is cut off, so that the power supply of the prize ball paid-off ball detection switch 86C (DC12V-B) and the control board power supply from the stop of the driving of the prize ball solenoid 86E. The performance required for the maintenance time of the compensation voltage of (DC5V) can be relaxed, and an inexpensive configuration of the power supply substrate 12 becomes possible.

  The DC12V-B regulator 223 is used as a dedicated power source for a switch such as a prize ball paid-off ball detection switch 86C, and is used exclusively for low-power electric components with relatively low power consumption.

  Next, the DC5V regulator 224 is used as a control power source for the ICs 38, 138, etc., and is also used for charging the electric double layer capacitor 230 for storing a backup power source.

The DC5V regulator 224 is adapted to receive an output stop signal from the delay circuit 2 2 9 As described above, when the second power supply interruption detecting circuit 227 detects a power failure, after a predetermined time delay The output is forcibly stopped. The predetermined time is a time required for backup processing such as storage of the payout remaining number in the main control board 14 and the payout control board 16. As a result, it is possible to maintain the time during which the DC12V-B can operate and to perform detection processing by the accurate paid-out ball detection switch 86C.

  In the power supply control circuit having the above-described configuration, when a power failure occurs, first, a voltage drop is detected by the second power-off detection circuit 227 and notified to the main control board 14 and the payout control board 16. Since the power supply voltage at this time is a state in which each control board is operable, each control board executes a predetermined power-off process.

  In the present embodiment, the power-off process is performed for the state immediately before the power failure after the power failure is restored. At this time, since there is information that must be stored, the information is stored in the RAM 142 of the IC 138. Since this RAM 142 can maintain the storage state by the power supply voltage (about 4.5 V) supplied from the electric double layer capacitor 230 during the power failure, the RAM 142 can retain the information until after the power failure is restored. .

  The operation of the first embodiment will be described below with reference to the flowcharts of FIGS.

  First, main control will be described with reference to the flowchart of FIG.

  In step S100, it is determined whether the start of the program is due to power-on (or power recovery) or a periodic reset signal. This determination is made based on the presence or absence of specific data written once in the power-on monitoring area of the RAM 42 when the power is turned on.

  If there is specific data, it is determined that the program is started by a periodic reset signal, and the process proceeds to step S101. If there is no specific data, it is determined that the program is started when the power is turned on, and the process proceeds to step S123 to perform initialization processing. This step S123 is a routine that is processed only once at power-up, writes certain data into the power-on monitoring area after executing RAM42 initialization. As a result, when the program is started after the next time, it is determined that the program is started by the periodic reset signal in step S100, and the process proceeds to step S101. In addition, after the process of step S123, it waits for a periodic reset signal.

  In step S101, general game processing is performed. In step S102 to step S104, which is shifted from step S101, a winning ball number command transmission process by winning balls and an addition process to the remaining winning ball counter are performed. The present embodiment is characterized in that the configuration is such that a prize ball number command is transmitted to the payout control board 16 regardless of whether or not a prize ball can be paid out. This is because the payout ball is backed up by the payout control board 16, so that it is possible to accurately store and retain the remaining number of prize balls even in the event of an unexpected power failure or the like.

  First, in step S102, it is determined whether or not there is a winning ball (pachinko ball that has won a winning opening). If there is no winning ball, the process proceeds to step S105, and if there is a winning ball, step S103. Then, a prize ball number command which is an instruction of the number of prize balls for the winning ball is transmitted to the payout control board.

  Thereafter, the process proceeds to step S104, and the prize ball payout number of the prize ball payout number command transmitted is added to a prize ball payout remaining number counter provided in the RAM. This prize ball payout remaining counter indicates the number of prize balls to be paid out from now on, and whether or not the number of prize balls instructed by sending the prize ball payout number command has been paid out correctly by the payout control board 16. This is used to confirm an error with respect to the prize ball payout result.

  Next, in steps S105 to S108, it is determined whether or not a prize ball can be paid out, and a control for transmitting a prize ball permission command or a prize ball prohibition command, which is the determination result, to the payout control board 16 is performed. .

  First, in step S105, it is determined whether or not the status of whether or not the prize ball can be paid out has changed. This step S105 is for transmitting the command only at the state change point. This determination as to whether or not the prize ball can be paid out is made by the prepared ball detection switch 86A and the overflow switch 86B. Determines that the prize ball cannot be paid out.

  If the status of enabling / disabling of the winning ball has not changed, the process proceeds to step S109. If the status has changed, the process proceeds to step S106, and the determination in step S105 indicates that the winning ball can be paid out. Judge whether there is. If the prize ball can be paid out, the process proceeds to step S107, a prize ball payout permission command is transmitted, and the process proceeds to step S109. If the prize ball cannot be paid out, the process proceeds to step S108, a prize ball payout prohibiting command is transmitted, and the process proceeds to step S109.

In the process of step S109 and step S118~ step S122, a step of confirmation of the back Kua-up process in the dispensing control board 16 (payout based on the prize balls paid out remaining number), First, in step S109, the backup process is completed Is determined based on the presence or absence of the specific code of the backup process end flag in the RAM 42. If there is a specific code, it is determined that the backup has been completed, and the process proceeds to step S110 to perform an error check process for the winning ball payout result. .

  If there is no specific code, it is determined that the backup has not ended, and the process proceeds to step S118 to confirm the backup end.

  In step S118, it is confirmed whether or not the prize ball is permitted. If the prize ball is not authorized, the process waits for a periodic reset signal. This is because if the prize ball is not permitted, the prize ball is not paid out, so that it is not possible to confirm the end of the backup process.

  In the case of the winning ball permission state, the process proceeds to step S119, and it is determined whether or not the signal state of the winning ball paid-out ball detection switch 86C has not changed for 3 seconds or more. If there is a change in the signal state of the winning ball paid-out ball detection switch 86C, it is determined that backup processing is in progress (the remaining number of winning balls is being paid out), and a periodic reset is awaited. If there is no change in the signal of the winning ball paid-out ball detection switch 86C for 3 seconds or more, the process proceeds to step S120, and it is determined whether or not 3 seconds or more have passed since the prize ball paying ball number command was transmitted last. If 3 seconds or more have not elapsed, the system waits for a periodic reset signal. If 3 seconds or more have elapsed, it is determined that the backup processing has ended, and the process proceeds to step S121.

  In step S121, the winning ball payout remaining number counter is cleared, and in step S122, a specific code is written in the backup end flag of the RAM 42 in order to store the completion of the backup processing.

  This is because the backup completion confirmation method in step S119 and step S120 is because the winning ball remaining value that the main control board 14 is backed up cannot be grasped by backing up the winning ball on the payout control board.

  The process in step S120 is a step provided to perform the launch and the general game process without waiting for the end of the backup process in order not to give the player unpleasant feeling, and is shown in FIG. As described above, when the backup processing end determination is performed only in step S119 and the winning ball payout remaining number counter is cleared, a negative count corresponding to the number of winning ball payouts based on the signal state of the winning ball payout ball detection switch 86C is performed. The purpose is to prevent problems.

  Next, in the processing from step S110 to step S117, error confirmation processing is performed for the prize ball payout result.

  In step S110, a prize ball payout ball is detected. If a prize ball payout ball is detected, the process proceeds to step S111. If no prize ball payout ball is detected, the process proceeds to step S115. In step S111, the prize ball payout remaining number counter value is subtracted, and in step S112, a prize ball excess error check is made as to whether or not the prize ball has been paid out excessively.

  If the winning ball payout remaining counter value exceeds -50, it is determined that there is a winning ball excess error, and the process proceeds to step S113 to transmit a winning ball prohibition command. Thereafter, in step S114, the player or the pachinko parlor is notified by an indication or voice that there is an error with respect to the result of paying out the prize ball.

  On the other hand, if the prize ball payout remaining number counter value does not exceed -50 in step S112, the process waits for a periodic reset signal.

  A series of processing from step S115 to step S117 is processing for confirming a prize ball failure error that prize balls for the number of prize balls designated by the prize ball payout number command are not paid out.

  First, in step S115, it is confirmed whether or not the prize ball is permitted. If the prize ball is not authorized, the process waits for a periodic reset. This is because when the prize ball is not permitted, no prize ball is paid out, so that a prize ball failure error is not determined.

  If the winning ball is permitted, the process proceeds to step S116, and the remaining winning ball counter value is checked. When the counter value is 50 or less, the process waits for a periodic reset, and when it exceeds 50, the process proceeds to step S117.

  In step S117, it is determined whether or not the signal state of the winning ball paid-out ball detection switch 86C has not changed for 3 seconds or more.

  If there is a change in the signal state of the winning ball paid-out ball detection switch 86C, it is determined that there is no winning ball failure error, and a periodic reset signal is waited for.

  If there is no change in the prize ball paid out ball detection switch signal for 3 seconds or more, it is determined as a prize ball failure error, and in the same manner as the prize ball excess error, the process proceeds to step S113 and a prize ball prohibition command is transmitted. A player or a pachinko parlor is informed by an indication or voice that there has been an error in the result of paying out a prize ball.

  In step S112 and step S116, the range of the prize ball payout remaining number counter value is given because the prize ball error frequently occurs due to the count error between the main control board 14 and the payout control board 16 due to noise or the like. This is to prevent it.

  Next, payout control will be described with reference to the flowchart of FIG.

The payout control is configured by main loop processing and timer interruption without using a system activated by a periodically generated reset signal.
(Main processing)
In step S200, an initialization process is performed that is performed only once when power is turned on (or when power is restored). In this initialization process, a return process of the remaining number of winning balls as backup data is performed. Further, the prize ball permission state flag is cleared, and the prize ball is prohibited when the power is turned on. By this process, the prize ball payout is stopped until a prize ball permission command is received from the main control board 14. In addition, timer interrupt settings, INT interrupt permission, etc. are performed. After this process, the process shifts to an infinite loop and waits for the start of the timer interrupt process and the INT interrupt process.
(Timer interrupt processing)
In steps S300 to S307, the command received from the main control board 14 is decoded by the INT process and the process associated therewith is performed.

  First, in step S300, it is determined whether or not a command has been received from the main control board 14. If a command is received, the process proceeds to step S301. If no command is received, the process proceeds to step S308.

  In step S301, a command decoding process is performed. In step S302, it is determined whether or not the command is a winning ball permission command. If it is a winning ball permission command, the process proceeds to step S303, and the winning ball permission state flag in the RAM 142 is set. If it is not a winning ball permission command, the process proceeds to step S304.

  In step S304, it is determined whether or not the received command is a prize ball prohibition command. If the command is a prize ball prohibition command, the process proceeds to step S305 to clear the prize ball permission state flag in the RAM 142. If the command is not a prize ball prohibition command, the process proceeds to step S306.

  In step S306, it is determined whether or not the received command is a prize ball number command. If it is a prize ball number command, the process proceeds to step S307, and the received prize ball number is added to the prize ball payout remaining number counter value. If it is not a prize ball number command, the process proceeds to step S308 without processing as an invalid command. .

  Next, in Step S308 to Step S314, the remaining number of prize balls is paid out.

  First, in step S308, it is determined whether or not the winning ball is permitted. This determination is made based on whether or not the winning ball permission state flag of the RAM 142 is set. If it is set, it is determined that the winning ball is permitted, and if it is not set, it is determined that the winning ball is prohibited.

  If it is determined that the winning ball is permitted, the process proceeds to step S309. If it is determined that the winning ball is prohibited, the process proceeds to step S314, and the driving of the winning ball solenoid 86E is stopped (de-energized) and then returned from the timer interruption. .

  On the other hand, in step S309, it is confirmed whether or not the prize ball payout remaining counter value is zero. If it is zero, it is determined that there is no need to pay out, and the process proceeds to step S314 to drive the prize ball solenoid 86E. After stopping, the process returns from the timer interrupt in step S316.

  If the winning ball remaining number counter value is not zero, the process goes to step S310 to perform payout, and the winning ball solenoid 86E is driven (excited). After the prize ball solenoid 86E is driven, it is confirmed in step S311 whether or not a prize ball payout ball is detected. If it is detected, the process proceeds to step S312 and the prize ball payout remaining number counter value is subtracted, and then to step S313. Transition.

  On the other hand, if no winning ball paid-out ball is detected, the process proceeds to step S315. In step S313, it is confirmed whether or not the prize ball payout remaining number counter value is zero. If it is zero, it is determined that the prize ball payout for the number of prize balls received from the main control board 14 is completed, and step S314 is executed. , The driving of the prize ball solenoid 86E is stopped, and then the process returns from the timer interruption.

  If the prize ball payout remaining counter value is not zero in step S313, it is determined that the prize ball payout for the number of prize balls received from the main control board 14 has not ended, and the timer allocation is performed while the prize ball solenoid 86E is driven. Return from the beginning.

  In step S315, an error state in which no winning ball payout ball is detected despite the driving of the winning ball solenoid 86E is confirmed. Specifically, it is determined whether or not the signal state of the winning ball paid-out ball detection switch 86C has not changed more than tERROR (here, 5 seconds). If there is no change for 5 seconds or more, it is determined that the prize-ball-paid-off ball detection switch 86C is a fatal error, and the process proceeds to step S314. In step S314, the driving of the prize ball solenoid 86E is stopped to return from the timer interrupt.

  On the other hand, if no change in the signal state of the winning ball paid-out ball detection switch 86C is less than 5 seconds, it is determined that there is no fatal error, and the timer interruption is resumed while the winning ball solenoid 86E is being driven.

This step S315 is added because the main control board 14 cannot grasp the detailed operation state of the payout control board 16 (driving state of the prize ball solenoid 86E), and in the payout control board 16 after the power is restored. This is an effective process for the purpose of interpolating a problem that an error cannot be confirmed for a prize ball payout result during backup processing.
(INT interrupt)
This INT interrupt is activated when a command is transmitted from the main control board 14, and receives a command from the main control board 14 in step S400. After receiving the command, return from INT interrupt.
(NMI interrupt)
This interruption is a power-off process that is started when a power-off occurs and the signal from the second power-off detection circuit 227 becomes active (detects a power-off state). In step 500, a specified time for detecting a winning ball paid out to be paid out after the power is turned off is set in the backup timer. The specified time is a value that can detect all the balls that have been paid out through the prize ball paid-off ball detection switch 86C after the prize ball solenoid 86E is in a non-excited state due to power-off and has stopped paying out the prize balls. To.

  Next, the process proceeds to S501, where it is confirmed whether or not a winning ball paid out ball is detected. If not, the process proceeds to S503. On the other hand, when a winning ball paid-out ball is detected, the process proceeds to step S502, the prize ball paying-out calculation count value is subtracted, and then the process proceeds to step S503.

In step S503, the backup timer is subtracted, and the process proceeds to step S504 to check whether the backup timer is zero. In this case the backup timer is zero, prize balls paid out remaining required to pay out the prize balls paid out number of remaining unpaid coin min after transition to the power returned to S505 it is determined that the specified time described above has elapsed In order to protect the number 142A (prize ball backup data), the RAM 142 is subjected to a write prohibition process and waits for a reset. Note that it is also possible to protect the winning ball backup data by prohibiting access to the RAM 142 only by the reset waiting process.

  On the other hand, if the backup timer is not zero in S504, it is determined that the specified time has not elapsed, the process proceeds to S501, and the same processing is repeated until the backup timer becomes zero.

  As shown in the first embodiment, a command from the main control board 14 is received by an interrupt (INT) with a configuration in which the control of the payout control board 16 is a loop system without using the periodic reset system. As shown in FIG. 9, a plurality of commands can be transmitted to the payout control board 16 in one process between periodic reset signals in the main control board system 14.

  In addition, the power-off detection signal from the second power-off detection circuit 227 is input to the NMI that is an unmaskable interrupt terminal because the processing for generating the power-off requires urgency.

  Next, based on the timing chart of FIG.

  When the power interruption occurs (see arrow A in FIG. 10), the voltage of the power supply (DC12V-A) applied to the prize ball solenoid 86E becomes equal to or lower than the suction holding voltage of the prize ball solenoid 86E, that is, the non-excited state. The prize ball payout stops (see arrow B in FIG. 10).

  When the payout of the last payout is detected after the stop of the payout of the prize ball at the timing of the arrow B (refer to the arrow C in FIG. 10 after the time t1 from the arrow B here), Subtract from a number. In order to enable this processing, the power supply (DC12V-B) of the winning ball paid-out ball detection switch 86C and the operating power supply (DC5V) of the payout control board 16 are set to have their respective operation guarantee voltages longer than the time t1 (t3). ) Maintained (t1 <t3). Note that the time t3 may be determined in advance by experiments or the like, and determined by considering safety.

Next, when the second power supply interruption detecting circuit 227 of the power supply board 12 detects the power-off and outputs the power-off signal (see arrow D in FIG. 10). This power-off signal is input to the NMI terminal of the IC 138 of the payout control board 16 via the terminal 204J. When the IC 138 detects a power-off by this input, the power-off process is executed with the highest priority.

  In other words, the number of remaining prize balls stored in the RAM 142 is stored in the memory for protection. After that, the control program waits for reset by an infinite loop. Thereby, it is possible to prevent the data from being destroyed or the program from running away. The reset is applied when the operating power supply (DC5V) of the payout control board 16 becomes equal to or lower than a predetermined value, thereby stopping the operation of the control system (see arrow E in FIG. 10).

  Thereafter, the switch power supply (DC12V-B) is also cut off (see arrow F in FIG. 10), and the device function is completely stopped.

  When the power supply is restored after a while (see arrow G in FIG. 10), the respective power supplies start up, but the reset release of the main control board 14 and the payout control board 16 is performed by the action of the DC5V power supply monitoring reset circuit 50, 150. All power sources used in the control board (including the power failure detection signal in the case of the payout control board 16 using the power failure detection signal) are restored after returning to the normal state (after the arrow H in FIG. Here, see arrow I in FIG. 10).

  Here, in the above timing chart, when the power supply for high power (DC12V-A) is cut off and the prize ball solenoid 86E is in a non-excited state (see arrow B in FIG. 10), the prize ball has been paid out. One of the requirements is that the power supply of the winning ball paid-off ball detection switch 86C maintains the operation guarantee voltage of the switch for the maximum time (t1) required for detection (t1 <t3). Separately, when the power supply for high power (DC12V-A) is cut off and the prize ball solenoid 86E is in a non-excited state (see arrow B in FIG. 10), the longest time required for detecting a prize ball paid out ball (t1) As described above, it is also an important requirement that the operation of the dispensing control board 16 is possible (t1 <t2).

  According to the above timing chart, since the guaranteed voltage of the switch, that is, the low power supply (DC12V-B) is maintained for a time longer than DC5V, the main control board 14 and the payout control board 16 have the 5V power supply monitoring reset circuit. Until it is reset by 50, 150, it becomes possible to perform accurate switch input including the detection of winning and paying balls.

  As described above, in this embodiment, even when an unexpected power interruption such as a power failure occurs, the remaining payout can be accurately stored. After the power is restored, the remaining payout is based on the stored payout. Therefore, the game can be continued without causing any disadvantage to both the player and the pachikon store.

  Further, in this embodiment, in addition to achieving the final object, the following effects can be obtained.

(1) Separate connection of prize ball paid-out ball detection switch signal to main control board and payout control board Signals from prize ball paid-out ball detection switch 86C are independently input to main control board 14 and payout control board 16 Therefore, the main control board 14 can confirm whether or not the number of balls instructed to the payout control board 16 by the prize ball payout number command has been paid out correctly. By this confirmation processing, it is possible to check that the prize ball payout number command to the payout control board 16 has been illegally modified.

  That is, the main control board 14 uses the signal from the prize ball paid-out ball detection switch 86C for appropriate confirmation, and the payout control board 16 uses the prize ball paid-in solenoid detection switch 86C to drive the prize ball solenoid. It is possible to establish a division of labor that is used to control the stop timing.

(2) Performance of power supply of prize ball paid-out ball detection switch 86C As a backup system of the present embodiment, the minimum required performance required for the power supply of the switch detecting the prize ball paid-out ball is to stop driving the prize ball solenoid 86E. Therefore, the operation guarantee voltage of the switch is held for at least the longest time required for detecting the winning ball payout ball. As a result, it is possible to store and retain the exact number of winning balls paid out when the power is turned off.

  The power supply of the award ball paid-off ball detection switch of this embodiment is DC12V, and since a power consumption current such as a prize ball solenoid 86E is connected to the DC12V power supply, the holding time after the power supply is cut is shortened. The last prize ball payout ball may not be detected. Therefore, a switch-dedicated power supply (DC12V-B) different from the 12V power supply (DC12V-A) that consumes a lot of power is configured to have a longer holding time so that the winning ball to be paid out last can be accurately detected. did.

  Also, if the power supply of the winning detection switch 56 is cut off when the main control board 14 is operating normally, even if the winning detection switch 56 has no winning ball, a signal indicating that there is a winning ball is erroneously output, and there is a winning. May be judged.

  Therefore, if a power source dedicated to this switch is used as the power source of the winning detection switch 56, an accurate winning ball can be detected.

  The power source for switching, that is, the power source for low power (DC12V-B) may be provided on the main control board 14 or the payout control board 16. Can be used as a common power source.

(3) Performance related to operation maintenance time of main control board and payout control board As a backup system of the present embodiment, the main control board 14 and the payout control board 16 detect at least a prize ball paid out ball from the stop of the prize ball solenoid drive. It is required to operate normally as much as possible for the longest time required for. As a result, it is possible to store and retain the exact number of winning balls paid out when the power is turned off.
(Second embodiment)
11 and 12 show a second embodiment of the present invention. Since the basic configuration is the same as that of the first embodiment, the description of this configuration will be omitted with the same reference numerals, and only the characteristic configuration of the second embodiment will be described.

  The feature of the second embodiment is that, in the first embodiment, the prize ball payout is stopped by the natural return (non-excitation) by turning off the power for the prize ball solenoid 86E when the power interruption occurs. In the second embodiment, the power-off notice signal (PWDN1) for detecting the power-off is provided at a time earlier than the power-off detection signal (PWDN2), and the driving of the prize ball solenoid 86E is stopped by this PDWN1 signal. .

  Note that the stop of driving of the prize ball solenoid 86E by the power-off notice signal can be detected by the CPU 140 (stop configuration) in which the drive is stopped (software configuration), or can be stopped directly by this signal (hard configuration). is there.

  By adopting the configuration of the second embodiment, the prize ball payout stop is promptly performed at a predictable time without depending on the power supply falling characteristic of the prize ball solenoid 86E (time varies depending on current consumption). Is possible.

  In the second embodiment, a circuit for generating a power-off notice signal (first power-off detection circuit 226) is provided on the power supply board 12. However, a configuration in which the circuit is provided on the payout control board 16 is also possible.

However, the configuration provided in the power supply board 12 has an advantage that it can be used as a common circuit across models.
(Third embodiment)
FIG. 13 shows another embodiment of a timing chart when power is turned off and when power is restored.

  The feature of the third embodiment is a configuration for performing all processing required when the power is turned off based on the power-off detection signal (prohibition of paying out a winning ball → detecting a winning ball to be paid out last → saving protection of winning ball backup data). It is in the point.

With this configuration, it is possible to delete (pass) the recovery process due to momentary power interruption (power interruption for a time that is short enough that the power interruption detection signal does not become active). It is possible to facilitate the inspection. (Fourth embodiment)
FIG. 14 shows another embodiment of the CPU resetting method.

The feature of the fourth embodiment is that the reset is performed within the guaranteed operation voltage of the CPU 140. A power-off detection signal is input to the NMI of the CPU 140, and a signal is sent to the power-off detection signal via a delay circuit. A reset signal is sent to the CPU 140. The performance required for the delay circuit 229 is the following two points.
(1) The falling delay time tRON is less than the time when the DC5V power supply satisfies the operation guarantee voltage of the CPU 140 from the activation of the power-off signal, and more than the time necessary for the NMI processing.
(2) The cutoff delay time tROFF is equal to or longer than the time required for resetting the CPU 140 as the control system when the power is turned on.

  With the above configuration, it is possible to reliably perform reset within the operation guarantee voltage of the CPU 140.

  The delay circuit may be provided on the power supply substrate 12.

  Other functions and effects of the present embodiment (including the first to fourth embodiments) are as follows.

  Since the electric double layer capacitor 230 for backup is charged via the Schottky diode 228 from the DC5V power generated by the power supply board 12, the forward voltage drop of the Schottky diode 228 is small, and an appropriate voltage is set. A backup power source can be generated. Further, since the electric double layer capacitor 230 is used, a circuit for a backup power source can be created with a simple configuration.

  Further, the power supply board 12 is provided with a first power-off detection circuit 226 and a second power-off detection circuit 227, which can notify each control board by a power-off detection signal before the ICs 38 and 138 are completely down. Therefore, it is possible to reliably execute the predetermined power-off process.

  In the present embodiment, an integrated circuit of the CPU 40 (CPU 140), the ROM 44 (ROM 144), and the RAM 42 (RAM 142) is applied as the IC 38 (IC 138), which is optimal for noise resistance. , Each may be a separate body.

  Further, the power-off detection signal may be input to the payout control board 16 by NMI (non-maskable interrupt), polling from a general input port, or INT (interrupt).

  Furthermore, in this embodiment, the payout ball backup function is provided to the payout control board 16, but there is no problem if the main control board 14 is provided with the prize ball backup function. This is because the output signal of the prize ball payout detection switch is input to both the main control board 14 and the payout control board 16.

In this embodiment, the power supply voltage to the launch control board 24 is supplied via the relay board 26. However, the power supply voltage may be further supplied via the relay board 26 via the payout control board 16. . In the case of this configuration, it is possible to integrate the launch control signal transmitted from the payout control board 16 to the launch control board 24 and the connector wiring for supplying the power supply voltage, so that the workability of connector insertion and removal can be improved. it can.
(Fifth embodiment)
FIG. 15 shows a power supply board 12A according to the fifth embodiment. In FIG. 15, only the main part is described. Note that the full-wave rectifier circuit, the smoothing circuit, and the DC5V regulator in FIGS. 5 and 11 are not characteristic parts in the fifth embodiment, and are shown as block diagrams.

  The power supply board 12A is provided with a power plug 200 for connecting to a pachinko store island side power outlet in order to be supplied with power. The power plug 200 is connected through a terminal 204 for inputting power to the power supply board 12A to a full-wave rectifier circuit 210 that is grounded in order to convert AC power into DC power. A grounded smoothing circuit 220 is connected to the full-wave rectifier circuit 210 in order to remove the pulse component of the DC power supplied from the full-wave rectifier circuit 210. A grounded DC 5V regulator 500 is connected to the smoothing circuit 220 in order to stabilize the power supply voltage supplied from the smoothing circuit 220 to 5V. Note that the DC5V regulator 500 is not limited to DC5V, and a plurality of DC5V regulators 500 may be provided so as to generate a necessary voltage value. A grounded terminal 204 is connected to the DC5V regulator 500 in order to supply the output from the DC5V regulator 500 to the outside from the power supply board 12A. The anode side of the Schottky diode 228 is branched from the DC5V regulator 500 and the terminal 204, and the cathode side of the Schottky diode 228 is connected to the grounded electric double layer capacitor 230. A power supply line for supplying power is further branchedly connected to the power failure time detecting means 502 from the middle of the branch line connected to the anode side of the Schottky diode 228 from between the DC5V regulator 500 and the terminal 204. The power supply line may be branched from between the Schottky diode 228 and the electric double layer capacitor 230. A signal line is connected to the interruption means 504 from the power failure time detection means 502. A branch line is connected to the blocking means 504 in order to supply power from between the cathode side of the Schottky diode 228 and the electric double layer capacitor 230. Further, the blocking means 504 is connected to the terminal 204.

  FIG. 16 shows a configuration example of the power failure time detection unit 502 and the cutoff unit 504.

  As shown in FIG. 16, the power line of the power failure time detection means 502 is branched from between the terminal 204 and the Schottky diode 228, and the power failure time detection means 502 side of the branch line is the anode side of the Schottky diode 510. Connected with. On the other hand, a grounded electric double layer capacitor 512 is connected to the cathode side of the Schottky diode 510, and a timer IC 514 (for example, μPD5555 manufactured by NEC) is connected between the cathode side of the Schottky diode 510 and the electric double layer capacitor 512. For example, the branch line is connected to the power supply terminal of the timer IC 514. In addition, a grounded capacitor 516 is connected to the discharge terminal of the timer IC 514, and a resistor 518 is provided between the timer IC 514 and the capacitor 516, and between the cathode side of the Schottky diode 510 and the electric double layer capacitor 512. In order to supply power to the timer IC 514, the branch line is further branched and connected to the branch line. Further, a branch line is connected to the trigger terminal of the timer IC 514 from the anode side of the Schottky diode 510 of the power supply line of the power failure time detection means 502, and a cutoff means 504 is connected to the output terminal of the timer IC 514. . In addition, the GND terminal of the timer IC is grounded.

  The output terminal of the timer IC 514 is connected to the base side of the NPN transistor 522 via the resistor 520. The emitter side of the NPN transistor 522 is grounded. In addition, a resistor 524 is connected between the emitter side and the base side of the NPN transistor 522 so that the NPN transistor 522 performs a stable operation. The collector side of the NPN transistor 522 is connected to the base side of the PNP transistor 528 via the resistor 526. A branch line from between the Schottky diode 228 and the electric double layer capacitor 230 is connected to the emitter side of the PNP transistor 528 as a backup power supply line. In order for the PNP transistor 528 to operate stably, a resistor 530 is connected between the emitter side and the base side of the PNP transistor 528. In order to output the backup power supply, the collector side of the PNP transistor 528 is connected to the terminal 204.

  The operation of the fifth embodiment will be described below.

  While power is supplied from the island-side power supply to the power supply board 12A, the electric double layer capacitor 512 is charged from the DC5V regulator 500 through the Schottky diode 510.

  When a power failure occurs (see FIG. 17), the electric charge stored in the electric double layer capacitor 512 flows as a current to the branch line between the Schottky diode 510 and the electric double layer capacitor 512 by the Schottky diode 510. Is the power supply for the timer IC 514. At the same time, the timer IC 514 starts timing by using the branch line connected to the timer IC 514 from the anode side of the Schottky diode 510 as a trigger when DC5V is cut off.

  Since the theoretical expression of the output pulse width (delay time) of the timer IC 514 is proportional to the product of the resistance value of the resistor 518 and the capacitance value of the capacitor 516, the resistance value of the resistor 518 and the capacitance value of the capacitor 516 are By setting, the backup time t4 by the timer IC 514 is specified. It may be possible to change the setting of the backup time t4 from the outside by using a variable type in which either the resistance value of the resistor 518 or the electric capacitance value of the capacitor 516 can be changed.

  Based on the backup time t4 set in this way, the timer IC 514 outputs an H level signal until a specified time (backup time t4) elapses from the occurrence of a power failure, and an L level signal after the specified time (backup time t4) elapses. Is output to the blocking means 504 (see the signal in FIG. 17B).

  When an H level signal is input from the timer IC 514 to the base side of the NPN transistor 522 via the resistor 520, the NPN transistor 522 is turned ON, and the collector of the NPN transistor 522 is connected from the base side of the PNP transistor 528 via the resistor 526. Current flows to the side.

  At this time, the PNP transistor 528 is turned ON, and the electric charge stored in the electric double layer capacitor 230 passes through a branch line connected between the electric double layer capacitor 230 and the Schottky diode 228 to the emitter side of the PNP transistor 528. It flows to the emitter side of the PNP transistor 528.

  The voltage drops at a point A that is equipotential to the electric double layer capacitor 230 (see the signal in FIG. 17A), and also drops at a point C on the collector side of the PNP transistor 528 (see the signal in FIG. 17C).

  A current flows from the point C to the terminal 204 and becomes a backup power supply current.

  When an L level signal is input from the timer IC 514 to the base side of the NPN transistor 522 via the resistor 520, the NPN transistor 522 is turned OFF, and the collector of the NPN transistor 522 is connected from the base side of the PNP transistor 528 via the resistor 526. No current flows to the side.

  At this time, the PNP transistor 528 is turned OFF, and the charge stored in the electric double layer capacitor 230 is connected to the branch line connected between the electric double layer capacitor 230 and the Schottky diode 228 to the emitter side of the PNP transistor 528. The PNP transistor 528 does not flow to the emitter side.

  The voltage drops at a point A that is equipotential to the electric double layer capacitor 230 (see the signal in FIG. 17A), and also drops at a point C on the collector side of the PNP transistor 528 (see the signal in FIG. 17C).

  The current stops flowing from the point C to the terminal 204, and the backup power supply current is cut off.

The circuit is designed so that the discharge curve of the backup power source (see the signal in FIG. 17A) can maintain the voltage that can be stored in the RAM until the specified time has elapsed. (Sixth embodiment)
Next, a sixth embodiment will be described. The power supply board according to the sixth embodiment is the same as the power supply board 12A according to the fifth embodiment shown in FIG. 15 described above. .

  As shown in FIG. 18, in the sixth embodiment, the configurations of the power failure time detecting means 502 and the blocking means 504 according to the fifth embodiment shown in FIG. 16 are different (details will be described later).

  FIG. 18 shows the configuration of the power failure time detection means 502 and the interruption means 504 according to the sixth embodiment.

  A grounded discharge resistor 540 is connected in the middle of the power supply line branched from the Schottky diode 228 and the grounded electric double layer capacitor 230 to the cutoff means 504.

  The power failure time detection means 502 is branched from the terminal 204 and the Schottky diode 228 and is connected to the anode side of the Schottky diode 510. The cathode side of the Schottky diode 510 is connected to a grounded electric double layer capacitor 512. A power supply line to the comparator 542 is branched and connected between the cathode side of the Schottky diode 510 and the grounded electric double layer capacitor 512. A resistor 544 connected in series to a grounded resistor 546 is connected in the middle of a branch line connected between the Schottky diode 510 and the electric double layer capacitor 512 to the comparator 542. A non-inverting input terminal of the comparator 542 is branchedly connected between the resistor 544 and the resistor 546. On the other hand, the inverting input terminal of the comparator 542 is connected in the middle of the backup power supply line from between the Schottky diode 228 and the electric double layer capacitor 230 to the cutoff means 504. As a signal from the power failure time detection means 502, the output terminal from the comparator 542 is connected to the base side of the PNP transistor 528 inside the interruption means 504 via a resistor 526. A backup power supply line is branched from the Schottky diode 228 and the electric double layer capacitor 230 to the emitter side of the PNP diode 528. In order to output the backup power supply, the collector side of the PNP transistor 528 is connected to the terminal 204.

  The operation of the sixth embodiment will be described below.

  When a power failure occurs, the charge stored in the electric double layer capacitor 512 flows as a current through a power supply line that is branched and connected between the Schottky diode 510 and the electric double layer capacitor 512 to the comparator 542.

  At the same time, a voltage is applied to the non-inverting input terminal of the comparator 542 through the resistor 544 further branched from the branch line.

  At this time, the voltage applied to the non-inverting input terminal of the comparator 542 has little variation in voltage value.

  On the other hand, the electric charge stored in the electric double layer capacitor 230 flows as a current through a power line connected to the cutoff means 504 from between the Schottky diode 228 and the electric double layer capacitor 230, and the like. The voltage at the point A of the potential decreases (see the signal in FIG. 19A).

  The inverting input terminal of the comparator 542 is connected to the inverting input terminal of the comparator 542 from the middle of the branching line connected to the cutoff means 504 from between the Schottky diode 228 and the electric double layer capacitor 230. A voltage is applied.

  The comparator 542 compares the voltage value applied to the non-inverting input terminal with the voltage value input to the inverting input terminal, and outputs a voltage signal corresponding to the magnitude relationship to the cutoff means 504 (FIG. 19B). ) Signal reference).

  That is, the specified voltage value set by the electric double layer capacitor 512 and the resistors 544 and 546 is compared with the voltage value of the electric double layer capacitor 230 by the comparator 542, and the comparison result is output to the cutoff means 504.

  When the backup power supply voltage value is greater than the specified voltage value, the output of the comparator 542 is shorted to GND.

  On the other hand, the base current of the PNP transistor 528 flows to the comparator 542 via the resistor 526, and the PNP transistor 528 is turned on. For this reason, the electric charge stored in the electric double layer capacitor 230 becomes a current, passes through the branch line connected to the cutoff means 504 from between the Schottky diode 228 and the electric double layer capacitor 230, to the emitter side of the PNP transistor 528. Flowing.

  A current flows from the collector side of the PNP transistor 528 to the terminal 204 to serve as a backup power source. (See signal in FIG. 19C).

  When the backup power supply voltage value is smaller than the specified voltage value, the output of the comparator 542 is open to GND.

  An output signal is not output from the comparator 542 to the base side of the PNP transistor 528 via the resistor 526. As a result, the base current of the PNP transistor 528 does not flow, so the PNP transistor 528 is turned off.

  For this reason, the electric charge stored in the electric double layer capacitor 230 does not flow as a backup power supply current from the collector side of the PNP transistor 528, and the backup power supply is cut off (see the signal in FIG. 19C).

  That is, when the backup power supply voltage value reaches less than the specified voltage value Vth, the voltage at the point C decreases, and power supply from the electric double layer capacitor 230 to the outside of the power supply device is interrupted.

  Here, the specified voltage value Vth is set so as to be the specified time (backup time) t5 (see FIG. 19).

  At this time, excessive electric charge of the electric double layer capacitor 230 is discharged through the grounded resistor 540.

  The specified voltage value Vth is set by the resistors 544 and 546, and is set to be equal to or higher than the voltage that can be stored in the RAM connected to the outside of the power supply device, and the positive terminal voltage of the electric double layer capacitor 512 is The variation is sufficiently small as compared with the discharge curve of the positive terminal voltage of the electric double layer capacitor 230. Alternatively, a reference voltage that does not fluctuate with a three-terminal regulator may be created as shown in FIG.

  While the fifth embodiment directly measures the time from the occurrence of a power failure, the sixth embodiment monitors that the voltage value of the electric double layer capacitor 230 is less than the specified voltage value. In this method, when the voltage value of the electric double layer capacitor 230 becomes less than the specified voltage value, the power supply from the electric double layer capacitor 230 to the outside of the power supply device is cut off. The variation parameter of the holdable voltage value can be ignored, and the variation in the backup time can be reduced as compared with the conventional method.

  By adopting this method, there is an advantage that the configuration scale of the power failure time detection means 502 and the interruption means 504 can be reduced as compared with the fifth embodiment.
