Abstract

PURPOSE:To obtain good cleaning performance over a long time by disposing plural cleaning surfaces on a cleaning member for cleaning a mirror surface and providing a means for replacing the cleaning surface by a new one. CONSTITUTION:A device is provided with a slide scanner 11 which is guided by a mirror 16 so as to be capable of moving back and forth in the longitudinal direction of the mirror 16 and a cleaning roller 12 as a cleaning member which is formed in the shape of a roller, and the cleaning roller 12 is pressed against the mirror 16 with a prescribed pressure so as to form nip DELTAl. As to the rotational amount of the cleaning roller 12, the nip quantity DELTAl is set so that the cleaning surface may be perfectly replaced by a new member by the cleaning roller 12 before transfer is performed again on the dirty mirror surface. And the mirror cleaning member can be replaced by a new surface little by little by the action of cleaning the mirror 16. Thus, the good cleaning performance can be always obtained over a long time.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a mirror cleaning device for cleaning a mirror surface of a copying machine, fax machine, printer, etc. by reciprocating the mirror in the longitudinal direction.

(Prior Art) Conventionally, as a device that reciprocates in the longitudinal direction and cleans the surface of a mirror, a device as shown in FIGS. 5 and 6 is known. It consists of a slide scanner 1 that is guided by a mirror 6 and can reciprocate in the longitudinal direction of the mirror 6, a cleaning member cleaning pad 2 held by the slide scanner 1, a motor 3, a pulley 5, and a wire 4 for driving the slide scanner 1. The cleaning pad 2 is pressed against the mirror surface with a constant pressure by the slide scanner 1 and the slide shoe 7. Normally (except when cleaning the mirror), a HP sensor (not shown) etc. is located outside the effective use surface of the mirror 6. is detected and waiting. The mirror 6 is cleaned by a mirror cleaning signal that is periodically sent after counting a certain number of copies or a certain number of copies. When a mirror cleaning signal is generated, the active motor 3 is turned on, and the slide scanner unit and cleaning pad 2 move back and forth while cleaning the mirror 6 (of course, they move forward with one cleaning signal and move backward with the next signal). ).

(Problem to be solved by the invention) Since the above conventional technology has only a single cleaning surface (clinip pad), the cleaning surface becomes dirty due to multiple cleaning operations, reducing the cleaning performance of the mirror. . On the other hand, as the mirror surface becomes more sophisticated and requires a leaner surface, dirt from the cleaning pad may be retransferred onto the mirror.

For this reason, in the prior art, it was difficult to select the material for the cleaning bat. In other words, a material is required that has sufficient cleaning performance and has a sufficient lifespan without causing stain retransfer. For this reason, commercialization is currently being hindered.

(Structure and operation of the invention) The present invention aims to solve the above problems, and provides that a cleaning member for cleaning a mirror surface has a plurality of cleaning surfaces, and has means for replacing the cleaning surfaces with new cleaning surfaces. It is characterized by

Hereinafter, a detailed explanation will be given based on an embodiment of the present invention shown in FIGS. 1 to 4. A slide scanner 11 that is guided by a mirror 16 and can reciprocate in the longitudinal direction of the mirror 6
A cleaning roller 12, which is a cleaning member formed in a roller shape, and an actuator 19 are provided.Furthermore, at the tip of the actuator 19, a one-way clutch 21 is connected to a worm gear 22 when the actuator 19 operates in the direction of the arrow in the figure.
It is installed so that it can be driven. Further, normally, the actuator 19 is stopped at the position shown in FIGS. 3 and 4 by the return spring 23 (because the one-way clutch is in the free direction).

The slide scanner 11 reciprocates the mirror 16 in the longitudinal direction by the drive wire 14 in response to the mirror cleaning signal.

This is the same as the conventional example.

The cleaning roller 12 is pressed against the mirror 16 with a constant pressure by the slide shoe 17 and the slide scanner 11 to form a nip Δp. By moving the slide scanner 11, the mirror 1 is
Clean the surface of step 6.

When the slide scanner 11 moves to the right in the figure and reaches one end of the mirror, the actuator 19 hits the mirror holding bracket (not shown), and the actuator 19 moves to the third end.
It can be rotated as shown by the arrow in the figure. actuator 1
Since a one-way clutch 21 is attached to the rotating shaft 9 so as to be locked when rotated in the direction of the arrow, the rotational force is transmitted to the worm gear 22 and causes the worm wheel 20 to rotate slightly. A cleaning roller 12 is attached to the tip of the worm wheel 20, and the cleaning roller 12 is attached to the tip of the worm wheel 20.
The nip portion configured as 6 is slightly rotated to bring a new cleaning surface to the nip position. The amount of rotation of the cleaning roller 12 is set so that the nip amount Δρ is completely replaced with a new member before the cleaning roller 12 starts retransferring dirt.

The cleaning roller 12 is driven by a worm gear 22
and a worm wheel 20, the cleaning roller 12 is prevented from rotating in the opposite direction due to pressure during cleaning. When the slide scanner 11 moves backward, the actuator 19 separates from the mirror holding bracket. At this time, since the one-way clutch 21 is in one direction, the worm gear 22 does not rotate, and only the actuator 19 is returned to the stopper 24 position by the return spring 23. In this manner, the cleaning member of the mirror 16 is gradually replaced with a new surface by the cleaning operation of the mirror 16, so that consistently good leaning performance can be obtained over a long period of time.

(Effects) According to the present invention, the cleaning member for cleaning the mirror surface has a plurality of cleaning surfaces and has a means for replacing the cleaning surfaces with new cleaning surfaces, so that the cleaning surface for cleaning the mirror is always replaced with the new cleaning surface. Since it can be replaced and cleaned, good cleaning performance can be obtained over a long period of time.
