Claims

[Scope of utility model registration request]

A printed wiring board on which electronic circuit components are attached and a plug part formed on the two ends, and a connector that receives signals and power by inserting the plug part of the printed wiring board. In the wiring board device, contact portions having different lengths are provided on the plug portion so that the plug portion contacts the power contact portion, the signal line contact portion, and the detection wire contact portion in this order when the plug portion is inserted, One end is connected to the contact part,
A contact detection circuit is provided whose other end is connected to the input and output buffer circuits on the printed wiring board, and is mounted on the printed wiring board by detecting contact/non-contact with the connector on the printed wiring board. 1. A printed wiring board device, characterized in that the printed wiring board device is configured to be detachable while the device is in operation, by stopping the operation of the electronic circuit and making the output on the connector side high resistance.
