Electronic filing devices for displaying on a display device or for printing by a printing device are known and used in various fields. Here, the units and devices such as the input device, the optical disc device, the display device, and the printing device described above are connected to the central processing unit (microcomputer) as external devices. In a normal electronic file device, initialization diagnosis processing is performed after the power is turned on.

However, in the initialization process of each unit / device in the initialization flow, the I / F (interface) of the unit / device has been conventionally used.
Regardless of whether the central processing unit is connected or not, the power is supplied to the selected target unit / device to perform the initialization process first, and during the initialization process, it is determined whether the I / F is connected or not connected. I / F of the unit / device
If is not connected, an error message is displayed or an error sound is sent to notify, and the process proceeds to the initialization processing of the next unit / apparatus, and the initialization is sequentially performed. That is, the initialization process is sequentially performed for units and devices that may not be connected. Therefore, not only the initialization time may become very long, but there is also a drawback that the power consumption accompanying the power supply increases because the target units / devices are sequentially initialized.
