Abstract

PURPOSE:To constitute a titled device so that the dust which has adhered to a cleaning body side once does not adhere on the upper face of a focusing optical transmission body array again by one time cleaning, by constituting so that the cleaning body contacts to the side face of the array in case of it moves from one end of the side face of the array to the other end, and it is detached from the side face of the array in case of it moves reversely. CONSTITUTION:A cleaner 5 is brought to the position of 1 by fitting and inserting a moving body into guide rails 2, 2' (the moving side of a small plate material 4 is set to the side where a special rail T exists). When the moving body moves, the cleaner 5 gets on an elastic body 6, is shifted onto the special rail T, and slides along it (shown by 2). In that case, the upper face of the cleaner 5 contacts to the lower face of a focusing optical transmission body array and excecutes cleaning. When the cleaner 5 goes over the special rail T, it drops and comes to the position of 4, namely, a position going along a rail 2c. In this way, the cleaner is shifted through the position 5 detached from the focusing optical transmission body array, and reaches a plate groove H (shown by 6).

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an improvement in a cleaning device for cleaning a convergent light transmitter array for exposing an original image on a document table on a copying machine body onto a photoreceptor surface. .

<Prior Art> A focusing light transmitting element array (Selfoc lens) has the advantage of shortening the light exposure length, and is used in many copying machines.

However, once the above-mentioned convergent optical transmitter array is removed from the unit to which it is fixed for cleaning, it is necessary to set it at the correct location when setting it again.
A copying machine equipped with such an array has the drawback of requiring a highly accurate positioning mechanism for adjustment.

In order to solve the above-mentioned problems, the applicant of the present application proposed a cleaning device J for a convergent light transmission array of a copying machine (Utility Application No. 56
-88510), "In a convergent light transmitter array for image-wise exposing the original image on the document table on the main body of a copying machine onto the photoreceptor surface, the upper surface of the convergent light transmitter array can be cleaned on the document table. A guide body is exposed when the kite is moved to a position and is provided parallel to the focusing light transmitting body array, and a cleaning member is fixed to the tip of the guide body that moves along the kite rest. A cleaning device for a convergent light transmitter array of a copying machine, comprising: a cleaner inserted between a document table and a convergent light transmitter array, the cleaning body being in contact with an upper surface of the convergent light transmitter array. disclosed.

However, in the above-mentioned cleaning device for a convergent light transmission array of a copying machine, when the cleaning body moves on the top surface of the array, the cleaning body moves from one end of the top surface of the array to the other end. The same surface of the cleaning body and the top surface of the array are always in contact with each other in the direction of movement of the cleaning body from the other end of the top surface of the array to the one end, so that once cleaned, the dust attached to the cleaning body side can be removed. will touch the top surface of the array again.

<Object of the Invention> Therefore, in the present invention, a cleaning device for a convergent light transmitting body array of a copying machine is improved. When the cleaning body comes into contact with the side surface of the array, and conversely moves from the other end to one end of the side surface of the convergent light transmitting body array, it is separated from the side surface of the array, and only in one direction of movement. The object of the present invention is to enable the cleaning body to slide on the side surface of the convergent light transmission body array to perform desired cleaning.

<Example> Hereinafter, the present invention will be described in detail with reference to the drawings.

In FIG. 1, 1il- is a convergent light transmitting array, which is fixed to a frame that mounts various mechanisms of the main body of the copying machine. The convergent optical transmitter array 1 is provided with two opposing idle rails 2.2'. On the other hand, what guide rail 2 is the convergent light transmitting body array I?
a seating part 2a seated on one side with a large area; and a seating part 2a extending from the seating part 2a, the tip of which is directly below the converging light transmitting body array 1 in a direction perpendicular to the light passing direction of the converging light transmitting body array 1. Extension body 2e having a rail 2c protruding to a nearby area
Release from. In addition, the guide rail lj on the other side includes a seating portion 2b seated on the other side of the area of the convergent light transmitting body array 10, and a seating portion 2b extending from the seat s2b with its tip extending in the light passing direction of the convergent light transmitting body array l. It consists of an extension body 2f having a rail 2d projecting vertically to a region immediately below the convergent light transmitting body array I. The rails 2c and 2dn are arranged in parallel positions.

A special rail T is provided in the middle of the extension body 2e of the guide rail 2 and runs parallel to the rail 2c of the guide rail 2.

The movable body that moves along the rails 2c and 2d of the guide rail 2 is as shown in FIG. There is. The rails 2c, 2d are in the grooves 3a, 3b.
K is pushed through, and the rectangular plate 3 moves along the guide rail 2.

A small plate 4 hinged to the rectangular plate 3 is provided at the rear of the rectangular plate 3, and the plane of the small plate 4 can be made at an arbitrary angle with respect to the plane of the rectangular plate 3 with one edge as an axis. It is movable.

A groove (which cannot be seen because it is hidden in the groove) is formed on the movable side edge of the small plate material 4 of the eye. A cleaner (cleaning member) 5 is fixedly mounted on the small plate 4 and has a planar uppermost portion, which is protruded at an angle with respect to the plane of the small plate 4. The position is changed by the rotation of the small plate side 4, but if the small plate 4 is on the same plane as the rectangular plate 3, as shown in FIG. 3(a),
The cleaner 5 is in a state separated from the convergent light transmitting body array I, and when the small plate 4 is at a predetermined angle with respect to the plane of the rectangular plate 3 as shown in FIG. 3(b), the cleaner 5 is in a state where it is adhered to the convergent light transmitting body array 1.

The position of this small plate 4 (that is, the position shown in FIG. 3 α or the position shown in FIG. 3B) is controlled by the special rail T of the guide rail 2 described above. This will be explained using FIG. 4. When the rectangular plate 3 of the movable body moves from one end of the side surface of the convergent light transmission array 1 to the other end, the small plate 4 is lifted along the special rail T to the position shown in FIG. 3(b). , the cleaner 5 contacts the convergent light transmitter array 1. At that time, the small plate material 4
In order to first place the object on the special rail T, an elastic body (made of P, E, T) 6 is attached to the special rail T.

On the other hand, when the rectangular plate 3 of the movable body moves from the other end to the one end of the side surface of the convergent light transmitting array (2), the small plate 4 separates from the special rail T and falls due to its own weight, and the cleaner 5 is separated from the convergent light transmitting body array 1.

Next, the cleaning operation of the convergent light transmitter array cleaning device of this embodiment will be described with a focus on the position of the cleaner 5.

gS5 is a side view of the guide rail 2, and as described above, the elastic body 6 is attached to one end of the special rail T formed in the middle of the guide rail 2. The inclination angle of this elastic body 6 is 15 degrees downward from the special rail T. Also, one end of the rail 2c of the guide rail 2 (the end with the elastic body 6) is located upward (special rail T side).
It is bent to form a bent body H. This bent body Hl″
i The small plate material 4, which has fallen due to its own weight, is re-raised as shown in Fig. 3(b).
The inclination angle is 15°.

Fig. 6 shows the moving position of the cleaner 5 in Fig. 5 above, and the following is the arrangement of the cleaner 5 in Fig.
0 Now, first, the movable body is fitted into the guide rails 2, 2' (when fitting, the movable side of the small plate 4 is connected to the special rail T). ) and bring the cleaner 5 above to position ■. The position marked with ■ will be called one end, and the opposite side will be called the other end. As the moving body moves from one end to the other, the cleaner 5 rides on the elastic body 6,
It moves onto the special rail T and slides along the special rail T (indicated by ■).

At this time, the upper surface of the cleaner 5 comes into contact with the lower surface of the convergent light transmitting element array, and the cleaner 5 slides on the lower surface to perform cleaning.

Then, when the cleaner 5 reaches the other end end position (3) of the special rail T and crosses the special rail T, the cleaner 5 falls to the position (2), that is, the position along the rail 2c. In this way, the cleaner 5 moves from the position (2) away from the convergent light transmitting body array and reaches the plate groove H (
■It is. ) Thereafter, cleaning of the side surface of the convergent light transmitting body array using the cleaner 5 is repeated a predetermined number of times in the same manner.

Therefore, when the cleaner 5 moves from the other end to the other end, it does not come into contact with the array, so that the deposits that were cleaned and removed, such as toner, come back into contact when moving from one end to the other end as described above. No adhesion to the array.

In the above embodiment, the cleaner cleans the surface facing the photoreceptor of the convergent light transmitter array, but the present invention is not limited thereto. It is also possible to have a configuration in which the facing surface is cleaned.

Effects> As described above, according to the present invention, there is provided a cleaning device for a convergent light transmitter array for imagewise exposing an original image on a document table of a copying machine main body onto a photoreceptor surface. When the cleaning body that cleans the side surface of the array moves from one end of the side surface to the other end, it comes into contact with the side surface, and conversely, when it moves from the other end of the side surface to one end, it separates from the side surface. Therefore, dirt such as toner attached during movement in one direction does not re-adhere to the convergent light transmitting body array when moving in the other direction.
The surface cleaning effect of the convergent light transmission body array can be ensured.
