Then, the peripheral device c was operated. Therefore, even if the switch of the electric device body a is turned off after the end of the work, the switch g of the peripheral device c is not turned off at the same time, and the power switch g of the peripheral device c is forgotten to be turned off.

Further, while using the hard disk or the like as the electric equipment main body a and the peripheral equipment c connected thereto, the user mistakenly operates the power switch g of the hard disk,
There was a problem that the power of the disk was turned off and the work contents were erased.

It is an object of the present invention to provide a peripheral device switch system which can solve the above problems.

It is characterized by being composed of a diode.

Further, the present invention is characterized in that, in the switch circuit of the above peripheral device, a switch circuit which can be operated by the main body of the electric device is built in the peripheral device.

[0009]

According to the present invention, when a switch of the electric device main body is turned on in the state where the peripheral device such as a hard disk is connected to the electric device main body, the switch circuit of the peripheral device connected to the main body operates, The power supply circuit of the peripheral device is turned on, and the peripheral devices are operated at the same time. On the other hand, when the switch of the main body of the electric device is turned off, the switch circuit of the peripheral device connected to the main body operates to stop the peripheral device at the same time.

In this way, by turning on / off the peripheral devices at the same time by operating the switches on the main body of the electric device, it is possible to prevent the peripheral devices from turning off or forgetting to turn off the power.
