When described in detail with reference to the accompanying drawings an embodiment of the present invention.

1 is a schematic block diagram of the present invention.

To connect the power supply 10 to the switch device 20 for selecting one of the ROM 2 32 having a program which can be used as a general computer and the ROM 1 31 which can be used as a specific program only. Consists of.

The power supply of the power supply device 10 is connected to other devices by the switch device 20. The switch device 20 is composed of a triac, a thyristor-diode.bridge, or a relay circuit as well as a mechanical switch. It may be used in connection with the control. The switch device 20 is configured to selectively connect one of the (1) or (2).

If the switch 2 is connected, the power supply is connected to the ROM 2 32 with a built-in program for use as a general computer, and automatically includes a timer 50 including a free operation timer having a plurality of channels. Processor 40, floating point and number processor FPU 60, interrupt controller 70, RAM 110, serial interface SIO 120, hard disk controller HDC 101 and hard disk drive HDD 102, present Real time clock RTC (130) displaying the elapsed time of the DMA, DMAC 150, which is a DMA controller to transfer data at high speed without intervening the main processor, expansion port (170) connected to the LED, keyboard controller KBC ( 160), keyboard KB (161), floppy disk drive controller FDC (91), floppy disk drive FDD (92), parallel interface PIO (141), parallel interface and connected to a separate processor and periodic device, printer driver and The printer head having the head 142, and the like VGAC (81), the monitor screen or LCD (82) for controlling the VGA is connected to the power-supply is operating.

If the switch 1 is connected, the ROM 1 (31) with the built-in program for use as a specific program dedicated computer automatically generates the timer 50, the main processor 40, the FPU 60, and the interrupt controller 70. ), RAM 110, SIO 120, HDC 101 and HDD 102, RTC 130, DMAC 150, LED PORT 170, KBC 160, KB 161, FDC ( 91), the FDD 92, the PIO 141, the printer 142, the VGAC 81, the monitor screen or the LCD 82, and the like are connected and operated.

In this way, the connection with the ROM 2 (32) or the connection with the ROM 1 (31) determines whether it operates as a general computer executing a general program or as a specific program dedicated device.

If switch 1 and switch 2 are selectively changed, spikes are likely to occur when connecting and disconnecting the switch, which may lead to damage to the ROM or malfunction of the main processor. In order to prevent this, a ceramic capacitor having good high frequency characteristics is provided with a capacitor (3) and a capacitor (4).

In addition, when the switch device 20 is connected to the ROM 2 (32) by connecting the switch (2) to operate a computer that performs a general program, pressing the function key 2 (162) in the interrupt generator 2 (190) main processor (40) An interrupt is generated, and the ROM 1 31 and the main processor 40 are connected by the switching circuit 179 by the main processor 40 to load a specific program-specific BIOS. For example, when the function key 2 162 is pressed again, the ROM 1 31 and the main processor 40 are blocked by the switching circuit 179 by the main processor 40 to block a specific program-specific BIOS. The switching circuit 179 may be replaced by a trigger device and a GTO thyristor drive circuit, a relay device, or a drive circuit and a timer off relay circuit.

In addition, when the switch device 20 connects the switch 1 and the ROM 1 31 and the power supply device 10 are connected to each other, the switch device 20 operates as a computer for executing a specific program. Interrupt occurs at the main processor 40 at 1191, the ROM 2 32 and the main processor 40 are connected by the switching circuit 179 by the main processor 40 to call a general program-specific BIOS. It is.

For example, when the function key 1 163 is pressed again, the ROM 1 31 and the main processor 40 are blocked by the switching circuit 179 by the main processor 40 to block the general program-only BIOS. The switching circuit 179 may be replaced by a trigger device and a GTO thyristor drive circuit, a relay device, or a drive circuit and a timer off relay circuit.

In addition, a DVD driver 201 and a DVD ROM 202 may be provided to receive a large amount of download by using communication or to transmit stored contents in a large capacity on a communication. It can be provided.

The microphone 205, the speaker 206, and the camera 207 can be connected to each other for communication or recording.

2 is an embodiment in which two trigger devices 181 and 183 and two GTO thyristors 180 and 182 are used as the switching circuit 179. When the switch device 20 is connected to the ROM 1 (31) by connecting the switch 1 and operates as a computer to execute a specific program and presses the function key 2 (162), the interrupt generator 2 (190) in the main processor 40 A low interrupt occurs, and a trigger occurs in the trigger device 2 (181) by the main processor 40 to conduct current to the GTO thyristor 2 (180). When the GTO thyristor 2 180 is turned on, the ROM 2 32 and the main processor 40 are connected to the general program dedicated BIOS. For example, when the function key 2 162 is pressed again, a reverse current is generated in the trigger device 2 181 by the main processor 40, and the current of the GTO thyristor 2 180 is turned off. When the GTO thyristor 2 180 is turned off, the ROM 2 32 and the main processor 40 are blocked to block the general program-only BIOS. The trigger device and the GTO thyristor may be replaced by a drive circuit and a relay device, or a drive circuit and a timer off relay circuit.

In addition, when the switch device 20 connects the switch 2 and the ROM 2 32 and the power supply device 10 are connected to each other, the switch device 20 operates as a computer that executes a general program. At this time, when the function key 1 163 is pressed, the interrupt generator 1 An interrupt is generated from the main processor 40 at 191, and a trigger is generated at the trigger device 1 183 by the main processor 40 to conduct current to the GTO thyristor 1 182. When the GTO thyristor 1 182 is turned on, the ROM 1 31 and the main processor 40 are connected to load a specific program-specific BIOS. For example, when the function key 1 163 is pressed again, a reverse current is generated in the trigger device 1 183 by the main processor 40 to turn off the current of the GTO thyristor 1 182. When the GTO thyristor 1 182 is off, the ROM 1 31 and the main processor 40 are blocked to block a specific program-specific BIOS. Here again, the trigger circuit and the GTO thyristor may be replaced by the driving circuit and the relay device, or the driving circuit and the timer off relay circuit.
