A detector mechanism for detecting the condition when a waste toner container is full of waste toner. A piston is provided which moves in response to the waste toner pressure in the waste toner container, a shutter is provided in the path of light irradiating the photoreceptor so as to close or open the light path, and a wire is provided which is connected between the piston and the shutter and forces the shutter to move in the direction for closing the light path according to the piston movement when the toner container is full of waste toner.

DETAILED DESCRIPTION The object of the present invention is to provide a waste toner container detector for detecting when the toner container is full and stopping the copying operation comprising a piston which moves in response to the waste toner pressure for easy and accurate detection of a full container, and a shutter provided in the path of a light which irradiates the photoreceptor which shutter closes the light path according to the piston movement thereby preventing an image from being copied when the container is full of waste toner.
The present invention comprises a piston moving in response to the waste toner pressure in the waste toner container, a shutter disposed in the path of light irradiating the photoreceptor so as to open or close the light path, and a wire connected between the piston and the shutter, forcing the shutter to shift in the direction for closing off the light path as the piston moves.
