Abstract

PURPOSE:To replenish a toner in a short time to a toner box without contaminating a hand and the circumference of the toner box by providing a toner vessel which closes one end opening part of a cylindrical body filled with the toner by a cap, and closes the other end opening part by a piston cap, and a push rod for pushing the piston cap. CONSTITUTION:When replenishing a toner into a toner box 3, a cap 7 of a toner replenishing port 6 is removed, a cap 14 of a toner vessel 10 is removed, also a seal tape 19 is peeled off, a small diameter opening part 13 of the toner vessel 10 is connected to the toner replenishing port 6 through a sealing material 22 as shown in the figure 3, a push rod 11 is connected to a piston cap 15 and the piston cap 15 is pushed in along a cylindrical body 12 by the push rod 11, and a toner 17 in the cylindrical body 12 is pushed out into the toner box 3 from the toner replenishing port 6 and replenished. When the toner 17 is supplied enough into the toner box 3, the toner vessel 10 is removed and the toner replenishing port 6 is closed by the cap 7.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a toner replenishment aid used when replenishing toner to a developing device installed in a copying machine.

Conventional technology The toner in the toner container is placed in the toner box of the developing device.
The toner is replenished by taking advantage of the fact that it falls due to gravity.

However, when replenishing in this way, if the toner container is an open type, the toner will scatter around the supply port of the toner box, making the operator's hands dirty. Due to the poor fluidity of the toner, it takes time to replenish the toner, and the toner container has to be vibrated, which is troublesome.

OBJECT OF THE INVENTION It is an object of the invention to reliably replenish toner into a toner box in a short time without staining hands or the area around the toner box.

Constituent Structure of the Invention The present invention includes a toner container in which one end opening of a cylindrical body filled with toner is closed with a cap and the other end opening is closed with a piston camp, and a push persimmon for pushing the piston cap,
By removing the camp* and b and pushing and moving the piston cap with a push rod, pressure is applied to the toner and the toner is forcibly pushed out through the opening at one end.

FIG. 1 on the undercurrent side is a schematic cross-sectional view of the developing device, in which a developing roll 2 is provided within the developing housing 1. As shown in FIG.

A toner box 3 is provided above the developer housing 1, and the toner 4 in the toner box 3 can be dropped and supplied into the developer housing 1 by rotating a supply roll 5.

A toner supply port 6 is formed in the upper part of the toner box 3, and is closed with a cap 7.

FIG. 2 is a sectional view of the toner supply aid.

The toner container 10 includes a toner container 10 and a pusher 11.
The small-diameter opening 13 of the cylinder 12 is held and closed by the cap 14, and the large-diameter opening (6) is closed by a piston camp 15 that can freely slide along the inside of the cylinder 12, and the toner is stored inside. 17 is filled, and a locking portion 1δ of the push rod 11 is formed on the piston cap 15.

19 is a sealing tape that covers the piston cap 15 with a layer of 12 Ktad.

The push rod 11 is composed of a rod 20 that fits and locks into the locking portion 18, and a handle 21.

Therefore, to replenish toner into the toner box 3, remove the cap 7 of the toner replenishment port 6, and then remove the cap 7 from the toner container 1.
At the same time as removing the camp 14 of 0, peel off the 7-rupee 119 and open the small diameter opening 1 of the toner container 10 as shown in FIG.
3 is connected to the toner supply port 6 via the sealing material 22, and the push rod 11 is connected to the piston cap 15.
1, the piston cap I5 is pushed in along the cylinder 12, and the toner 17 in the cylinder 12 is pushed out and replenished into the toner box 3 (through the toner supply port 6).

When the toner 17 is sufficiently supplied into the toner box 3, the toner container 10 is removed and the toner supply port 6 is filled with toner.
is closed with a cap 7.

In this way, the piston cap 15 applies pressure to the toner 17 in the toner container 10 to forcibly push it out and replenish it into the toner box 3, so it can be replenished reliably in a short period of time, and the surroundings of the toner box 3 and the operator I never get my hands dirty.

Effects of the Invention Toner can be reliably replenished into a toner box in a short time, and toner can be replenished without staining the area around the toner box or the operator's hands.
