Abstract
A portable telephone comprising an external antenna connector portion for connecting it to an external antenna can detect hook conditions by providing a detecting terminal utilizing a shield portion of the external antenna connector portion . In an on-hook condition where the portable telephone is mounted on an on-vehicle adapter , corresponding shield portions and of the external antenna connector portions and provided on both the portable telephone and the on-vehicle adapter come into contact with each other. On the other hand, in an off-hook condition where the portable telephone is disengaged from the on-vehicle adapter or the on-vehicle holder, the corresponding shield portions are out of contact from each other. The hook conditions can be thus detected by detecting the change in the contact between the shield portions.
