초록 ▼

A toner residual amount detecting mechanism comprises a stirring device and a photosensor. The photosensor has a protrusion, and rotates together with a stirring shaft while the protrusion contacts with a pin planted on the stirring shaft. The stirring device rotates by its gravity when it reaches a top dead point thereof. The stirring device also includes a magnetic rotor attracted by a permanent magnet in a sensor lever to thereby turn the sensor lever about the fulcrum of the sensor lever to a predetermined position. The sensor lever is stopped by a stopper when the stirring device reaches the bottom dead point thereof. The photosensor cannot detect light when the sensor lever is positioned at the bottom dead point since the light is intercepted by the sensor lever but can detect the light when the sensor lever reaches the predetermined position. The mechanism can inform an operator of a toner supply time since the photosensor operates depending on the resistance of toner against the stirring device.

대표청구항 ▼

In a toner residual amount detecting mechanism suitable for a developing device, wherein a photosensor detects the rotation of a rotor which rotates together with a stirring shaft in a hopper to indicate a toner supply time, said mechanism comprising: a pin which is planted in the stirring shaft; a rotor having a first end retained rotatably by the stirring shaft, a second end extending adjacent to the wall of the hopper and being formed with a magnetic material, the first end having a protrusion which is contacted with the side surface of the pin; a sensor lever disposed outside the hopper and having one end on which a permanent magnet is provided and turning adjacent to the locus of the magnetic material, the sensor lever turning on or off a photosensor at a bottom dead point thereof; and a stopper for stopping the sensor lever which turns together with the rotor to a second position where it turns on or off the photosensor.
