CAMERA APPARATUS FOR USE WITH AN ENDOSCOPE

摘要

A camera apparatus can be mounted on an endoscope to enable a picture to be taken of the interior of a coeliac cavity. The apparatus comprises a detecting device which detects whether the apparatus is or is not mounted on an endoscope. When the apparatus is mounted, the detecting device operates to supply power to an electrical circuit of the apparatus which requires energization only during a photographing operation, which power may be drawn from either an internal battery or an external power supply, thus minimizing the power dissipation of the internal battery.
