PURPOSE: To prevent any adverse influence such as noise or the like upon a device by continuously loading reset signals when loading/unloading a package to the device.

CONSTITUTION: This device is equipped with the circuit of a package 1 and the two kinds of long and short pins 21 and 22 for linking the package 1 to a mother board, and the pin 21 is linked to a ground on the mother board and used as the input of a reset circuit 3 in the package 1. Therefore, when loading/unloading the package 1, the pin 21 is linked and the pin 22 is not linked. According to this condition, a reset signal 23 can be made. Thus, while loading/unloading the package, the reset signal is continuously loaded and electric disturbance such as noise or the like is not exerted upon the device.
