Abstract

An operation state detection device comprises data communication devices and a detection device. The data communication devices are respectively attached to an operator, and a person or an object as an operation target. The data communication devices mutually perform data communication when the operator contacts the person or the object and thereby a path is formed through the operator, and the person or the object. The detection device detects the data communication performed between the data communication devices.

Claims

1. A communication apparatus comprising:

a transmitting electrode;

a reference electrode;

a voltage application circuit that applies a voltage for contact communication to an object including a living body between the transmission electrode and the reference electrode; and

a bypass circuit that connects the voltage application circuit in parallel with the transmission electrode and the reference electrode.

2. The communication apparatus as set forth in claim 1 wherein

one of a circuit that connects the transmission electrode and the reference electrode via the voltage application circuit or the bypass circuit selectively becomes active.

3. A communication apparatus comprising:

a receiving electrode;

a reference electrode;

a voltage detection circuit that detects a voltage for contact communication applied to an object including a living body between the receiving electrode and the reference electrode; and

a bypass circuit that connects the voltage detection circuit in parallel with the receiving electrode and the reference electrode.

4. The communication apparatus as set forth in claim 3 wherein

one of a circuit that connects the receiving electrode and the reference electrode via the voltage detection circuit or the bypass circuit selectively becomes active.
