Abstract

PURPOSE:To improve the efficiency of cleaning work in a shield case by dropping and housing dust scraped up from the inner surface of the case by allowing a cleaning member to slide in the case into a dust receiver provided outside the case. CONSTITUTION:The cleaning member 7 is provided in an insulating block 5 so that it may come in contact with the inner surface of the shield case 2 in order to remove the dust in the case 2 when a charger 1 is separated from the inside of the case 2 to the outside thereof. A large hole 12 through which the cleaning member 7 is allowed to pass almost in a non-contact state and the dust scraped up is dropped into a box when the charger 1 is separated from the case 2 is provided on the side wall 10a of the dust receiver 10 disposed at an aperture part 2a at one end side of the case 2, and a small hole 13 through which the member 7 is drawn is provided on the side wall 10b. After the dust in the case 2 cleaned by the member 7 is dropped and housed in the dust receiver 10 when the insulating block 5 passes through the large hole 12, the toner adhering to the member 7 is drawn and dropped through the small hole 13.

Further, in the present invention, specifically, for example, by providing a dust receiver on one opening side of the shield case, it is possible to collect the dust carried by the cleaning member. At this time, as a dust receiver, a cleaning member is passed in a box-shaped side wall which is in close contact with one opening side of the shield case in a substantially non-contact manner with the side wall. A large hole that can be dropped, and a small hole that allows a dust to adhere to the cleaning member to be squeezed into the box by passing the cleaning member in contact therewith on the side wall facing the above side wall Therefore, the inside of the shield case can be sufficiently cleaned, and specifically, dust can be collected by this, and the cleaning member itself can be cleaned. The large hole provided in the dust receiver has a size that allows the cleaning member to pass therethrough in a non-contact manner. Specifically, it is preferable that the large hole can insert and support the shield case. Also, on the other hand,
The small holes have a size that allows them to come into contact with and pass through the cleaning member, but the degree of contact varies depending on the material of the cleaning member. For example, in the case of felt, the length in which the small hole portion of the dust receiver bites into the felt is set to 1 to 3 mm. The same applies to a brush.

Further, the shield case 2 is placed on the horizontal support plate 8c in a state where the opening portion 2a at one end is inserted into the large hole of the dust receiver described later through the notch portion 8a of the front plate 8. On the other hand, the other end 2b is supported by screwing the hanging plate 2c to the rear plate 9, and on the side of the opening 2a, a box-like dust capable of containing the dust on the inner surface of the shield case 2 is provided. A receiver 10 is provided. That is,
As shown in FIG. 3, the dust receiver 10 is mounted on the mounting portion 11 corresponding to the cutout portion 8 a and fixed to the flange 8 c of the front side plate 8. When the charger 1 is separated from the shield case 2, the cleaning member 7 is passed through the side wall 10a of the dust receiver 10 in a substantially non-contact manner with the side wall 10a, so that the dust collected from the shield case 2 is put into the box. The cleaning member 7 is passed through the side wall 10b facing the side wall 10a and provided with a large hole 12 through which the cleaning member 7 can come in contact, so that dust adhering to the cleaning member 7 can be squeezed into the box. A small hole 13 is provided. Here, as described above, the shield case 2 has the one end 2a inserted into the large hole 12 and in close contact with the dust receiver 10, so that the dust collected by this can be reliably stored in the dust receiver 10. .

As a result, dust can be collected and the cleaning member itself can be cleaned. The large hole provided in the dust receiver has a size that allows the cleaning member to pass therethrough in a non-contact manner. Specifically, it is preferable that the large hole can insert and support the shield case. On the other hand, the small hole has a size that allows the small member to come into contact with and pass through the cleaning member, but the degree of contact varies depending on the material of the cleaning member. For example, in the case of felt, the length in which the small hole portion of the dust receiver bites into the felt is set to 1 to 3 mm. The same applies to a brush.

Further, the shield case 2 is placed on the horizontal support plate 8c in a state where the opening portion 2a at one end is inserted into the large hole of the dust receiver described later through the notch portion 8a of the front plate 8. On the other hand, the other end 2b is supported by screwing the hanging plate 2c to the rear plate 9, and a box-shaped dust capable of accommodating the dust on the inner surface of the shield case 2 on the opening 2a side. A receiver 10 is provided. That is,
As shown in FIG. 3, the dust receiver 10 is mounted on the mounting portion 11 corresponding to the cutout portion 8 a and fixed to the flange 8 c of the front side plate 8. Then, when the charger 1 is separated from the shield case 2, the cleaning member 7 is passed through the side wall 10a of the dust receiver 10 in a substantially non-contact manner with the charger 1 so that the dust collected from the shield case 2 is put into the box. large hole 12 is provided which can be dropped, and the side wall 10b opposite to the side wall 10a is (not crossed) passed in contact with this cleaning member 7, a box dust adhering to the cleaning member 7 thereby There is a small hole 13 that can be squeezed inside. Here, the shield case 2 is, as described above,
The one end 2a is inserted into the large hole 12 and is in close contact with the dust receiver 10, whereby the collected dust can be reliably stored in the dust receiver 10.
