有していた。 Conventional toner supply devices having a cartridge insertion section at the top include one in which the back side of the cartridge insertion section is open, as shown in Figure 1, and one in which the back side is sealed, as shown in Figure 2. There is. However, in the former case, when the toner cartridge 2 is inserted from the cartridge insertion slot 1 in the direction of the arrow a, the air inside the cartridge insertion part is pushed out, so that the toner cartridge 2 is
Air is discharged in this direction, and a large amount of toner 3 leaks out from the opening along with the air. Therefore, the area around the back side of the cartridge insertion portion and the inside of the copying machine are contaminated with toner. On the other hand, in the latter case, when the toner cartridge 2 is inserted from the cartridge insertion opening 1 in the direction of arrow a, there is no place for the air inside the cartridge insertion part to escape, so the toner cartridge 2, the guide cartridge 4 and the housing 5 Air is discharged from the gap between the cartridges in the direction of arrow b, and along with the air, a large amount of toner 3 is discharged from the cartridge insertion slot 1.
This has the disadvantage that the toner leaks outside and contaminates the area around the cartridge insertion slot 1 and the inside of the copying machine.

プ等にて、固定する。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the drawings, based on embodiments of toner supply devices for one-component and two-component electronic copying machines using a round toner cartridge system. First, as shown in FIG. 3, the toner supply device of the present invention is provided with a toner storage section 6 at the bottom for supplying toner into a developing device (not shown), and to the toner storage section 6, It has a structure in which a cartridge insertion part 8 for inserting a toner cartridge 7 for replenishing toner is provided at the upper part.
Housing 9 on the back side of the cartridge insertion section 8
In addition, an air outlet 10 is provided, and the air outlet 10 is covered with a filter 11 in order to prevent toner from leaking to the outside when the toner cartridge is inserted. The filter 11 is suitably made of, for example, Everlite Scotto HR-50 (filter manufactured by Bridgestone Tire Co., Ltd.), which has toner resistance, and is fixed with double-sided tape or the like.

得られる。 Further, in this embodiment, the cartridge insertion section 8
Although the air outlet 10 is provided in the housing 9 on the rear side, the air outlet 10 is not limited to this part.
If it is a place where the air inside the cartridge insertion part 8 can be exhausted when the toner cartridge 7 is inserted,
For example, the same effect can be obtained by providing the housing on both side surfaces (not shown) or the guide cartridge 12.

とができる。 In the toner supply device of the present invention, as shown in FIG. 3, when the toner cartridge 7 is inserted from the cartridge insertion port in the direction of the arrow a, the air inside the cartridge insertion portion is pushed out and the air discharge port 1
Although the toner is discharged from the toner through the filter 11, the toner does not leak to the back side due to the action of the filter 11. Moreover, since the air inside the cartridge insertion part is not compressed by the air being discharged, there is no toner leakage from the cartridge insertion opening. Therefore, it is possible to eliminate toner contamination around the conventional device that occurs when the toner cartridge is inserted.
次に、本発明の他の実施例を説明すると、第４

As shown in the figure, a cover plate 13 that opens on the back side of the cartridge insertion part and closes this opening is removably attached with screws 14, etc., and an air exhaust port 15 is provided in this cover plate 13. Air outlet 15
is covered with a filter 16.

ナーを除去できるため、より便利である。 In this embodiment, compared to the previous embodiment, the lid plate 13 is removable, so the filter 16 is not clogged with toner, and the toner does not get stuck between the toner cartridge and the lid plate 13. This is more convenient because the lid plate 13 can be removed and the toner can be easily removed when the toner is trapped and accumulated.

い。 Since the present invention has the above configuration, even when a toner cartridge is inserted from the cartridge insertion port to replenish toner, only the air inside the cartridge insertion portion is discharged from the air exhaust port.
There is no possibility of toner leaking outside. Therefore, it is possible to prevent the conventional problem of contaminating the area around the device with toner every time the cartridge is replaced, and the practical effects of the present invention are extremely large.
