Abstract

PURPOSE:To prevent a contamination caused by dropping of a toner, by providing a cylinder for rotating in a cartridge case together with a toner cartridge, in a gap between the toner cartridge and the cartridge case. CONSTITUTION:When installing a toner cartridge 1, a toner replenishing port 2 provided on the toner cartridge 1 is turned upward, engaged to a hollow part of a cylinder 4 in a cartridge case 3, guided horizontally, rotated by 180 deg., the toner replenishing port 2 is turned downward and a toner is replenished. When replacing the toner cartridge 1, the replenishing port 2 is positioned at the upper part of the cartridge case 3,and only the toner cartridge 1 is drawn out by leaving the cylinder 4. The toner dropped from the replenishing port 2 invades a hollow- gap part of the toner cartridge 1 and the cylinder 4, but does not invade in the hollow-gap part of the cylinder 4 and the toner cartridge 1, and the toner does not drop.

As shown in ←), first, the toner cartridge 1 is guided horizontally by engaging the hollow part of the cylinder 4 in the cartridge case 3 with the toner supply port 2 provided in the toner cartridge 1 facing upward. However, in case of misfortune, insert the toner cartridge 1 all the way and rotate it 1800 times as shown in FIG. At this time, the cylinder 4 is connected to the protrusion 1 provided at the supply port 2 of the toner cartridge 1.
0g and 10b engage with both ends of the slit 5 of the cylinder 4, and rotate as the toner cartridge l rotates. When the supply port 2 of the toner cartridge 1 rotates 180 degrees and comes directly below as shown in FIG. 2(A), it hits the end of the slit 8 provided in the cartridge case 3, stopping its rotation. Next, when replacing the toner cartridge 1, turn the toner installed in the cylinder 4 in the cartridge case 3 180 degrees in the opposite direction from when the toner cartridge 1 that has consumed the toner was installed. Position the supply port 2 at the top of the cartridge case 3 as shown in (b). After that, remove the cartridge case 3 from the cylinder 4.
Pull out toner cartridge 1, leaving only toner cartridge 1, and install new toner cartridge 1 according to the installation procedure described above.
Attach the cartridge case 3 to the cartridge case 3. At this time, the toner spilled from the supply port 2 enters the gap between the toner cartridge 1 and the cylinder 4, but the toner does not enter the gap between the cylinder 4 and the toner cartridge 1. Therefore, toner will not spill.
