Abstract
An endoscope provided with a photographing device includes a film feeding wire and a latch. The film feeding wire has its one end secured to the outer end of a film loaded in the photographing device which is disposed in the distal end of the endoscope. The other end of the film feeding wire is provided with a stop which has a larger diameter than the wire. The latch made of elastic material comprises a loop section and a latch section. The loop section is secured to the forward end of an operation wire extending through a sheath and usually has an opening larger than the stop of the film feeding wire. The latch section is connected to the loop section and adapted to hold the film feeding wire. When the film feeding wire is pulled into the latch section from the loop section outside the distal end portion of the endoscope, the film feeding wire is connected to the operation wire. For disconnection from the operation wire, the film feeding wire is pulled back into the loop section from the latch section.
