Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cleaning device, and more particularly to a cleaning device that is particularly useful for cleaning optical system members such as static elimination lamps used in copying machines and the like.

(Prior Art and Problems) An image forming apparatus such as a copying machine is provided with a discharging lamp for discharging the photoconductor and various other optical system members.

This type of optical system member needs to be cleaned because it is contaminated with toner powder or the like when used.

Since such an optical system member is incorporated in the main body of the apparatus such as a copying machine, it is not easy to clean it, and it is the current situation that it is performed by a service person or the like.

Therefore, the present invention aims to provide a cleaning device capable of cleaning such an optical system member and the like very easily and allowing the user to carry out cleaning by himself / herself without relying on a serviceman or the like. Subject.

According to the present invention, there is provided a cleaning device rotatably provided at an end of a photoconductor unit that is slidable relative to an object to be cleaned that is fixed inside the machine. The apparatus has a rotating shaft and a holding mechanism for holding itself upright, and a cleaning surface is formed only on one surface with respect to a relative sliding movement direction.
Provided is a cleaning device, which is provided such that the cleaning surface and the cleaning target are brought into contact with each other so that the cleaning is possible only when the photosensitive unit slides in one direction with respect to the cleaning target. It

(Embodiment) The present invention will be described in detail below with reference to specific examples shown in the accompanying drawings.

The following example shows a case in which the cleaning device of the present invention is applied to the cleaning of the discharge lamp of a copying machine.

In FIG. 1 showing a cleaning device of the present invention, this device comprises a main body 2 which is rotatably supported on a predetermined base portion 1 at an end portion of a photoconductor unit.

In this cleaning device of the present invention, a cleaning material 3 such as felt and brush is provided on one surface side of the main body 2, and the cleaning material 3 is rubbed against a predetermined cleaning object to perform cleaning. .

The present invention is characterized in that the main body 2 constituting the cleaning device is provided so that the main body 2 can be held upright.

Such self-holding can be performed very easily by providing an appropriate torsion spring 6 on the rotary shaft 5 as shown in FIG. 1, for example. Alternatively, a proper weight 7 may be provided on the lower portion of the main body 2 so that the center of gravity is located below.

FIG. 3 shows a case in which such a cleaning device is applied to cleaning the static elimination lamp of a copying machine.

That is, the static elimination lamp 11 is fixed in position on the main body 10 of the copying machine, and the photoconductor unit 12 including a photoconductor drum or the like is slidably provided so that it can be pulled out from the front surface portion 10a of the main body 10. ing.

Further, in general, it is desirable that the charge eliminating lamp 11 is provided at a position close to the photoconductor drum. A passage or a housing groove 15 for the protruding portion of the static elimination lamp 11 is provided therein.

Cleaning device of the present invention (designated as a whole by 20)
When the photoconductor unit 12 is accommodated in the accommodation space 13 of the copying machine main body 10, the photoconductor unit 12 is provided at the innermost position of the passage or the accommodation groove 15.

Therefore, when the photoconductor unit 12 is housed, the charge removal lamp 11, which is a cleaning target, is cleaned.

This cleaning mechanism will be described with reference to FIG.

That is, when the photoconductor unit 12 is housed in the main body 10 of the copying machine, the cleaning device 20 contacts the static elimination lamp 11 and rotates, and the photoconductor 12 enters inside with the cleaning surface in contact with the static elimination lamp 11. (State A in the figure).

It will be easily understood that the discharging lamp 11 is cleaned at this time.

On the other hand, when the photoconductor 12 is completely housed, the cleaning device 20 is in the upright state at the innermost side (state B in the drawing).

Further, in the cleaning device of the present invention, since the cleaning member is provided only on one surface side of the main body, when the photoconductor unit 12 is pulled out, as shown by C in the figure, the non-cleaning surface 20a of the cleaning device 20 is shown. Is the static elimination lamp 11
To be in contact with.

Therefore, since the dirty surface after cleaning does not come into contact with the static elimination lamp 11 that is the object to be cleaned, there is no possibility of the static elimination lamp 11 being re-contaminated.

The case where the cleaning device of the present invention is applied to the cleaning of the static elimination lamp of the copying machine has been described above as an example. However, in addition to the static elimination lamp, it is of course possible to apply cleaning of other optical system lenses such as self-hook lenses. The cleaning device of the present invention can be effectively used when a member that slides relative to an object to be cleaned is used outside the field of copying machines and the like.

(Advantageous Effects) According to the present invention, it is possible to effectively perform a part such as a static elimination lamp used in a copying machine, which is difficult to clean, without fear of recontamination, which is extremely useful for free maintenance.
