Abstract
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.
Claims7
A camera apparatus adapted to be mounted on an endoscope, said apparatus comprising:
- a first electrical circuit located in said camera which must be energized both during a photographing operation and when no photographing operation is in progress;
- a second electrical circuit located in said camera which must be energized during said photographing operation;
- a battery located in said camera for energizing at least said first electrical circuit;
- a connection terminal located on said camera and adapted to be connected to an external power supply associated with the endoscope when said camera is connected to the endoscope;
- and
- detecting means for detecting whether said camera apparatus if mounted on an endoscope, said detecting means connecting said connection terminal to said second electrical circuit during said photographing operation when said camera apparatus is mounted on the endoscope.
