[0001]
[Technical field to which the invention belongs]
The present invention relates to a gaming machine having a power failure detection circuit, and more particularly to improvement of the power supply device.
[0002]
[Prior art]
Game machines such as pachinko machines and pachislot machines are supplied with AC 24V power, and this AC 24V power is rectified to DC with a rectifier circuit composed of bridge diodes, smoothed with a smoothing circuit, and constant voltage The circuit had a power supply device that outputs a constant voltage. If the power output from this power supply device contains a lot of ripple components, there is a possibility that a game control device or the like to which power is supplied from the power supply device may malfunction. Was used to sufficiently remove the ripple component.
[0003]
[Problems to be solved by the invention]
Since the power supply device of the gaming machine uses a large-capacity electrolytic capacitor for the smoothing circuit, a large inrush current flows in the initial stage of charging the electrolytic capacitor when the power is turned on, exceeding the rated current of the rectifier circuit. The diode could be damaged. In order to prevent this inrush current, it has been proposed to prevent the inrush current by inserting an element such as a thermistor or a thyristor into a power supply line between the rectifier circuit and the smoothing circuit.
[0004]
However, the gaming machine retains (backs up) the current gaming state such as a big hit state, a probability variation state, and the number of undischarged balls even when the power is cut off so that the player is not penalized when the power is suddenly cut off. It is configured as follows. This backup outputs a power failure detection signal when the power failure detection circuit (voltage monitoring means) provided in the power supply device detects a drop in the power supply voltage, and controls the operation of the control device (game control device, discharge control device, etc.). Stop and start a backup of the current gaming state. In order to reliably detect this drop in the power supply voltage, the voltage variation after rectification and smoothing must not be large. However, if the thermistor or thyristor described above is used to prevent inrush current, the voltage drop due to current flow is not constant due to variations in the characteristics of these elements, and power failure cannot be detected reliably. there were.

In addition, the current suppressing means has a simple structure, and the reliability can be improved. In addition, an inrush current at power-on can be prevented without affecting the power failure detection accuracy, and the bridge diode is not damaged by an overcurrent.

[0046]
  The power supply device 250 includes a power circuit 251,MonitoringA circuit 253 and a backup power supply circuit 256 are provided.
[0047]
The 24 volt AC power received by the gaming machine 1 via the external terminal 42 from the island facility of the game store is supplied to the power supply device 250. This 24 volt AC power supply is introduced into the power supply circuit 251.
[0048]
The power supply circuit 251 includes a rectifier circuit that converts alternating current into direct current, a constant voltage circuit 264 that reduces fluctuations in output voltage, and smoothing circuits 262 and 265 that eliminate ripple components, and is supplied with 24 V AC supplied to the gaming machine.

The smoothing circuits 262 and 265 are configured to store the power to be supplied to the CPU for a short time even if the power supply voltage supplied to the gaming machine is lowered.
[0049]
MonitoringThe circuit 253 compares a predetermined reference voltage with the output voltage (5 V) of the power supply circuit, and generates an interrupt signal for the CPU as a power failure detection signal when the voltage of the power supply circuit decreases.

[0051]
FIG. 4 is a circuit diagram showing a configuration of a main part of the power supply apparatus 250 according to the embodiment of the present invention.
[0052]
The 24 volt AC power received by the gaming machine 1 via the external terminal 42 from the island facility of the game store is supplied to the input terminal 260 of the power supply device 250. The power supply device 250 includes an electrical game device (variable display device 8, variable winning device 10, ball hitting device 550, discharge unit 600, flow path switching unit 700, etc.), control device (game control device 100, discharge control device 200, A predetermined voltage to be supplied to the decoration control device 300, the display control device 350, the sound control device 400, the launch control device 500, and the like.
[0053]
A 24 volt AC power source supplied from the input terminal is converted (rectified) into 24 volt DC by a bridge diode 261 as a rectifying circuit composed of four rectifying diodes, and is a constant voltage regulator as a constant voltage circuit. H.264a, 264b. Between the bridge diode 261 and the constant voltage regulators 264a and 264b, a smoothing circuit including large-capacitance electrolytic capacitors 262a and 262b is provided, and a DC power supply containing a lot of ripple components output from the bridge diode 261 is provided. Remove ripple components. In addition, the electrolytic capacitors 262a and 262b back up necessary data even if the output voltage from the bridge diode 261 decreases due to a decrease in the supply voltage (AC24V), a failure of the power supply device, or the like. The power supplied to the game control device 100 or the like is stored for a short time. Further, capacitors 263a and 263b for preventing oscillation are connected in parallel with the electrolytic capacitors 262a and 262b.
[0054]
The constant voltage regulators 264a and 264b convert the smoothed 24V power source into a predetermined voltage (12V, 18V, etc.). Electrolytic capacitors 265a and 265b for stabilizing the output are connected to the output side of the constant voltage regulators 264a and 264b. Even if the output voltage of the constant voltage regulators 264a and 264b slightly varies, a stable voltage can be obtained. It is configured to output.
[0055]
  On the other hand, the inputs of the constant voltage regulators 264a and 264b are branched.MonitoringIt is also supplied to the circuit 253. thisMonitoringThe circuit 253 detects a drop in the power supply voltage and transmits a power failure detection signal to the control device 100 and the like to start a backup operation. The rectified power supply voltage divided by the two resistors 271 and 272 is compared with a reference voltage generated inside the voltage monitoring circuit 273 by the voltage monitoring circuit 273, and is lower than a predetermined voltage by the monitoring result. If it is determined that it has become, the internal output transistor is closed. As a result, the output of 5 volts maintained by the pull-up resistor 274 is reduced to zero volts. This output is input to the reset circuit 275, and the reset circuit 275 outputs a power failure detection signal (a pulse signal for a predetermined time (for example, 150 milliseconds)) so that the control device 100 or the like performs power failure processing. This power failure detection signal is sent to each control device via the buffer 276.
[0056]
A current limiting resistor 268 as a current limiting means is connected on the power supply line between the bridge diode 261 and the electrolytic capacitors 262a and 262b. The resistor 268 is short-circuited in parallel with the resistor 268 during operation. A relay 269 is connected as a short-circuit means. That is, the resistor 268 and the relay 269 constitute a current suppressing means, and when the relay 269 is in a normal state (non-operating state) and the contact is open, a current flows through the resistor 268, so that the electrolytic capacitor 262a, The current flowing through 262b decreases. On the other hand, when the relay 269 operates and the contact is short-circuited, no current flows through the resistor 268, so the current is not limited. One end of the operating coil of the relay 269 is connected to the output side of the constant voltage regulator 264a. When the output voltage of the constant voltage regulator 264a exceeds the operating voltage of the relay 269, the relay 269 operates and the current limiting resistor 268 is connected. No current flows and the current limiting resistor 268 does not function.
[0057]
That is, when the power is turned on, the output voltage of the constant voltage regulator 264a is zero volts, so the relay 269 is not operating, and the current limiting resistor 268 is inserted in the power supply line between the bridge diode 261 and the electrolytic capacitors 262a and 262b. It is in. At the same time as the power is turned on, 24V power is output from the bridge diode 261, so charging of the electrolytic capacitors 262a and 262b starts. However, since the current limiting resistor 268 is inserted, the charging of the electrolytic capacitors 262a and 262b is required. Is reduced, and the peak current when the power is turned on is reduced. When the electrolytic capacitors 262a and 262b are charged and the voltage across the capacitors rises, the output voltage of the constant voltage regulators 264a and 264b also rises. The limiting resistor 268 is short-circuited, no current flows through the current limiting resistor 268, the current limiting resistor 268 does not function (non-operating state), no voltage drop occurs, and the output of the bridge diode 261 remains unchanged as the constant voltage regulator 264a. 264b.
[0058]
In this way, when the power is turned on, the current limiting resistor 268 is inserted into the power line, and after the electrolytic capacitors 262a and 262b are sufficiently charged, the current limiting resistor 268 is short-circuited by the relay 269. Inrush current associated with charging of the electrolytic capacitors 262a and 262b at the time can be prevented, and the relay 269 having less variation in the drop voltage than the semiconductor element is used for short-circuiting the current limiting resistor 268. Power failure detection can be ensured. Needless to say, even if a relay is not used for short-circuiting the current limiting resistor 268, an element with little variation in the drop voltage may be used, and a semiconductor element may be used as long as the element has such characteristics with little variation in drop voltage.
[0059]
Moreover, the power supply for operation | movement of the relay 269 as a short circuit means was acquired from the output side of the constant voltage regulator 264a. Therefore, since a constant voltage, which is the output of the constant voltage regulator 264a, is applied to the operation coil of the relay 269, no overvoltage is applied to the relay 269, and the relay 269 is not damaged. Further, since the electrolytic capacitor 265a is connected to the output side of the constant voltage regulator 264a, the output voltage of the constant voltage regulator 264a is delayed from the rise of the input voltage (the electrolytic capacitors 262a and 262b in the previous stage are sufficiently charged, Since it rises (after the subsequent electrolytic capacitor 265a is charged), there is no need to use an expensive delay type relay having a special (complex) structure.
[0060]
The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
