DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backup device installed between a commercially available video game machine and an AC adapter attached to the video game machine to prevent memory erasure due to sudden power stop or the like.

[0002]

2. Description of the Related Art Conventionally, there is a backup device of a type which is inserted between a game machine main body and an AC outlet of a power supply. However, once the power supply is switched to a backup power supply, the backup state is not displayed and the battery is not displayed. The process was performed continuously until the discharge was completed.

[0003]

In the method described in the prior art, the backup battery is continuously operated until the discharge of the battery is completed. At the same time, it is difficult to notice that the power is cut off and the battery is in the backup state. However, the power supply release switch of the backup circuit must be operated.
As mentioned above, improvement of the battery in terms of economy, insufficient display, and lack of functionality is an issue.

[0004]

According to the present invention, a voltage detection circuit and a timer circuit are provided in a device installed between a game machine main body and an AC adapter attached to the game machine. A voltage detection circuit detects the presence or absence of a power supply input, and a circuit that switches to a backup power supply battery intermittently as soon as the input voltage is lost, and a timer circuit that stops the switched battery power supply for a fixed time. . When the timer circuit reaches a certain time, the backup battery power supply is turned off. However, the timer circuit is provided with a push button switch for extending the time so that the time can be extended as necessary. Also, the game machine body, the backup device of the present invention, and the AC adapter have a structure in which electrical connection and physical connection are simultaneously performed so that the game machine body and the attached AC adapter are separated and the device is easily installed therebetween. , And the three are made into one unit.

[0005]

When the power of the game machine is cut off while the game is in progress on the video game machine, the game screen which has been progressing up to that time instantly returns to the initial screen. If you do not want to restart the game that you have been struggling with from the beginning, make sure that the power supply of the game machine is not cut off even momentarily. I have to switch to In the apparatus of the present invention, a method of preventing current from flowing from the dry battery side while the voltage of the AC adapter is alive by always applying a voltage slightly lower than the supply voltage from the AC adapter to the AC adapter power supply line. did. (Refer to the circuit diagram of FIG. 1 for the following explanation.) At the same time, the current from the dry battery is
A switching circuit for separating the AC adapter circuit A from the battery circuit B using a PNP transistor T1 so as not to flow backward to the C adapter circuit A was provided. A
The dry battery power supply circuit for setting the voltage slightly lower than the C adapter voltage is provided with an adjustable three-terminal regulator IC1 that can finely adjust the output voltage. Until that time, the output voltage of IC1 is supplied to the power supply line B connected to the game machine while maintaining the voltage set by the voltage adjustment resistor R4. Next, a timer circuit for backing up for a fixed time and automatically stopping the backup is mainly constituted by IC3, C4 and D3. The line A from the AC adapter is mainly supplied to the CPU and the memory circuit in the game machine.
The line E from the C adapter is a power line mainly for operating the image and audio circuits in the game machine, and C is a common negative line for A and E. Therefore C
Since only the power supply line A supplied to the PU and the memory circuit needs to be backed up, no backup circuit is particularly provided on the line E side. By doing this, A
The function to notify the player of the game that the backup state has been entered is provided by stopping the sound and the image which are operated by the voltage on the line E side of the C adapter at the time of the backup. The power from the line E of the AC adapter is reduced to a constant voltage by the three-terminal regulator IC2 and D4
Is supplied to the power supply of the IC 3. At the same time C by D3
While charging 4, the input terminal of IC3 is kept at a high level, and the output of IC3 is inverted by IC4 and supplied to the base of driver T4 of switching circuit T2 of the battery circuit via R7. When voltage is coming to the E line,
The output of the three-terminal regulator IC2 is C4 through D3.
, The input terminal of IC3 keeps the high level, and at the same time keeps conducting T2, so that the battery B1 is added to the voltage regulating three-terminal regulator IC1. The output voltage of IC1 is changed from AC adapter line A to T1 as described above.
Line B is set slightly lower than the voltage
The battery B1 is not consumed because it does not flow in the direction. T
1 indicates that the voltage of E is applied to the base of T3 as long as the voltage is applied to E, so that the conduction state is maintained and the voltage of A is guided from the AC adapter power supply to the game machine power supply circuit B. Next, when the supply of the voltages of the power supplies A and E from the AC adapter is stopped, T1, which has been in a conductive state by the power supply from E, is turned off, and the output voltage of the IC1 starts to be supplied to the line B game machine power supply circuit. The battery is backed up. At the same time, the output voltage of the IC2 connected to the line E is also stopped, so that the supply of the voltage to the D3 and D4 is stopped and the voltage charged in the C4 also starts to be discharged by the R5. Starts to supply the voltage set slightly lower than the output voltage of IC2, but since only the input voltage of IC3 is not supplied, the discharge of C4 progresses due to R5, and the input voltage of IC3 falls below the threshold voltage. Is stopped, the timer operation is completed and the backup state is stopped. The timer time is set to 1-2 minutes, but if this time is not enough, the timer time can be extended by pressing the time extension push button switch S1,
Use this button if you need extra long-time backup status because the backup status will be kept as long as you hold down the button. Normally, the AC power circuit breaker temporarily works due to overcurrent of the home electric appliance, etc., or the time to return to normal operation, or if the game machine is in another room in another room.
A backup time setting of one to two minutes should be sufficient when the game machine is unplugged and moved to the display. In the embodiment of FIG. 1, since the B1 is a rechargeable battery using a nickel cadmium battery, the power supply circuit E is operated during the operation of the game machine.
To D1, R8, R9 and a circuit for charging display LED2 to charge B1. At the same time from B1 to T
2 is also used as a circuit that constantly compensates for the emitter current of IC2 and the idling current of IC1. This circuit is particularly effective to reduce the outflow current of the dry battery to 0 when a non-rechargeable dry battery is used. Using a relay for T
Even when the circuit is operated at 4, the emitter current of T2 can be omitted, but the idling current of IC1 flows, so this circuit is effective to compensate for this consumption. D5
D6 is a voltage drop for preventing the outflow of B1 other than at the time of backup by setting the voltage from B1 slightly lower than the voltage passing through D4 from IC2. LED1 turns off when the backup state ends. D1 and D4 are backflow prevention diodes. The IC1 has a function of automatically performing current control when the current exceeds the maximum current, but a fuse F1 is also inserted in the B1 circuit to prevent an overheating accident due to a short circuit or the like in the circuit. C
1, C2, C3, C5, C6 are bypass capacitors of the power supply circuit.
