This printed wiring board has first and second control wiring insertion parts (plugs), a power supply wiring insertion part, and a general signal wiring insertion part, and the power supply wiring insertion part has a first control wiring insertion part. It is formed longer than the wiring insertion part and shorter than the second control wiring insertion part and the general signal wiring insertion part. Furthermore, a gate control circuit for controlling opening and closing of the gate connected to each signal line is installed, and this gate control circuit has the first and second control wiring insertion parts connected to corresponding contacts in the connector. These gates are kept in the on state while the shortest first control wiring insert is not connected to the corresponding contact, and these gates are kept in the off state. therefore,
These gates are turned on at the end of the printed wiring board insertion process and turned off at the beginning of the removal process, resulting in
It is possible to prevent unstable signals in a transient state when a wiring board is inserted into or removed from a printed circuit board from being transmitted to other parts of the electronic device.
