Abstract

PURPOSE:To prevent foreign matters from entering a toner tank externally by providing the toner tank with a shutter and a lever which regulates the behavior of the shutter. CONSTITUTION:Title mechanism is provided with the lever 7 which possesses a rotating shaft in the sliding direction of the toner shutter 6, and a spring 8 which is bridged between the toner tank 4 and the lever 7. In condition where a toner cartridge 3 is not installed on a toner tank shutter 6, the part A of the lever 7 enters any notch of the toner tank shutter 6; therefore the toner tank shutter 6 can not be moved. On the other hand, when the toner cartridge 3 is installed on the toner tank shutter 6, the part P of a cartridge case 1 pushes the part B of the lever 7; therefore the part A of the lever 7 slips off any notch of the toner tank shutter 6, and the toner tank shutter 6 can be moved. As a result, foreign matters can be prevented from entering a toner tank externally.

A toner tank 4 that stores the necessary toner,
A toner tank cover 5 installed at the top of the toner tank 4 and having an opening, a toner shutter 6 that slides over the toner tank cover 5 to open and close the opening of the toner tank cover 5, and a toner shutter 6 that extends in the sliding direction of the toner shutter 6. A lever 7 having a rotating shaft, a toner tank 4 and a lever 7
and a spring 8 suspended between.

。When the toner cartridge 3 is installed on the toner tank shutter 6, the portion P of the cartridge case 1 pushes the portion B of the lever 7, as shown in FIG.
The portion A of is removed from a part of the notch of the toner tank shutter 6, and the toner tank shutter 6 can now be moved. The operator operates the toner tank shutter 6.
is moved in the direction of arrow Y, and an interlocking mechanism (not shown) interlocks the toner tank shutter 6 and cartridge shutter 2, thereby replenishing the toner tank 4 with the toner in the cartridge case 1. When finished, the operator moves the toner shutter 6 in the opposite direction of the arrow Y, returns the toner tank shutter 6 to its original position, and removes the toner cartridge 3. When the toner cartridge 3 is removed, the part A of the lever 7 is moved again. Because it enters a part of the notch in the toner tank shutter 6,
The toner tank shutter 6 cannot be moved.
