ABSTRACT:
A camera has a finger detecting device for indirectly detecting that a finger rests on an electronic flash and so forth due to unsuitable holding of the camera. The finger detecting device comprises a conductive member and an auxiliary electrode. The conductive member is disposed near the electronic flash and bared to outside of the camera. The auxiliary electrode is connected to the conductive member and disposed in the camera. A detecting electrode faces the auxiliary electrode via an insulating member. The finger is detected on the basis of change of capacity applied to the detecting electrode. Sensitivity of the finger detecting device is improved by changing the size of the auxiliary electrode without enlarging the conductive member. Accordingly, although the bared portion of the conductive member is small, the finger detecting device has a detecting performance which is similar to that of conventional one.
