Description

[Detailed Description of the Invention] The present invention relates to an original paper and photosensitive paper insertion guide for a copying machine, which is provided on a table for inserting original paper and photosensitive paper into a copying machine, and sets the insertion position of the original paper and photosensitive paper. .

Generally, a plate-shaped insertion guide is slidably provided on the table surface of a copying machine. This plate-shaped insertion guide is provided with a protrusion that contacts the edges of the original paper and the photosensitive paper, and sets the original paper and the photosensitive paper at appropriate insertion positions on the table. However, this insertion guide is held still only by the frictional resistance between the back surface of the insertion guide and the surface of the table. Therefore, when inserting the original paper and photosensitive paper, the insertion guide easily moves from position to position and cannot maintain a proper insertion position, which may cause problems in inserting the original paper and photosensitive paper. There is.

In view of the above points, the present invention effectively solves the problems of the prior art, has a simple configuration,
To provide an original paper and photosensitive paper insertion guide for a copying machine which allows the insertion guide to slide easily, securely fixes and holds an appropriately set insertion position, and is easy to operate.

According to the present invention, a board surface is placed on the surface of a table into which the original drawing paper and photosensitive paper are inserted, and a protrusion is provided on the board surface parallel to the direction in which the original drawing paper and photosensitive paper are inserted. an insertion guide for positioning the original drawing paper and photosensitive paper by means of the protrusion; and an insertion guide provided on the back side of the insertion guide for adjusting the insertion direction of the original drawing paper and photosensitive paper while holding the back end surface of the table. an insertion guide holding member that allows the insertion guide to slide in a right angle direction; a rotational shaft rotatably supports the insertion guide on the back surface of the insertion guide; This is achieved by providing a braking arm interposed between an elastic member that presses against the back surface to brake the insertion guide and the insertion guide.

Next, one embodiment of the present invention will be described in detail based on the drawings.

FIG. 1 shows a schematic diagram of a copying machine to which the present invention is applied. In the figure, the copying machine 1 is the copying machine main body 2.
An opening 3 provided on the front side of the printer is equipped with a table 6 that facilitates the insertion of original paper 4 and photosensitive paper 5. This table 6 has a smooth surface and can be smoothly inserted by placing the original paper 4 and the photosensitive paper 5 on top of each other and pushing them out into the opening 3 of the copying machine body 2. Further, a smooth plate surface of an insertion guide 7 is placed on the surface of this table 6, and a protrusion 8 is provided on this plate surface parallel to the insertion direction of the original drawing paper 4 and the photosensitive paper 5. There is. Place the original paper 4 and the photosensitive paper 5 on the table 6 and the insertion guide 7, press the edge 9 of the original paper 4 and the photosensitive paper 5 against the protrusion 8 of the insertion guide 7, and press the edge 9 of the original paper 4 and the photosensitive paper 5 against the protrusion 8. By pushing out the original paper 4 and the photosensitive paper 5 along the
The original paper 4 and the photosensitive paper 5 can always be inserted into the appropriate insertion positions of the opening 3.

Next, FIG. 2 shows a schematic diagram of an embodiment of the present invention. In the figure, parts having the same functions as those in FIG. 1 are given the same reference numerals. An insertion guide holding member 10 and a brake arm 11 are provided on the back surface of the insertion guide 7. The insertion guide holding member 10 is made of a material with excellent self-lubricating properties such as a fluorinated resin material, and is attached to the bent portion 7 on the back surface of the insertion guide 7.
A, and the bent end surface 6A of the table 6
A long groove 7B is provided to clamp the insertion guide 7, and prevents the insertion guide 7 from falling off and playing (play), while allowing smooth movement of the insertion guide 7 during the movement operation.

Further, the brake arm 11 is rotatably supported on the back surface of the insertion guide 7 by a rotation shaft 12. Tip part 1
3 is formed in the shape of a flat plate parallel to the back surface of the table 6, and a braking body with a high friction coefficient, a soft rubber plate 16 in this embodiment, is fixed to the surface corresponding to the back surface of the table 6. An elastic member, in this embodiment a spring 14, is wound around the rotating shaft 12 and interposed between the brake arm 11 and the insertion guide 7, and its spring force presses the soft rubber plate 13 against the back surface of the table 6. , brake the insertion guide 7. By braking the insertion guide 7, the position of the insertion guide 7 is sufficiently maintained even if the edges 9 of the original paper 4 and photosensitive paper 5 butt against the protrusion 8 or an unexpected external force is applied. .

Furthermore, when the handle 15, which is the end of the brake arm 11, is pulled up in the direction of the arrow P, the rotation of the brake arm 11 causes the soft rubber plate 16 to separate from the back surface of the table 6, so that the braking force exerted by the spring 14 disappears. . Therefore, the insertion guide 7 can be moved to any position on the table 6.

As described above, according to the present invention, an insertion guide holding member is provided on the back surface of the insertion guide, and is rotatably supported on the back surface of the insertion guide by a rotation shaft.
By fixing a brake body to the tip and providing a brake arm interposed between the insertion guide and an elastic member that presses the brake body against the back surface of the table and brakes the insertion guide, the structure is simple and the insertion guide It has advantages such as easy sliding movement, reliable fixing and holding of an appropriately set insertion position, and easy operation.
