Abstract

PURPOSE:To dispense with an auxiliary roller, to prevent the contamination of a picture and to achieve miniaturization by inserting a reading unit having a depth smaller than the diameter of a main roller between the upper and lower runs of an annular thin plate and making the thin plates transparent to read the image on the surface of the thin plate from the rear of said plate. CONSTITUTION:Each of main rollers 1 has a predetermined diameter and both rollers are arranged in parallel. A transparent thin plate 2 is composed of a thin transparent flat plate and formed as an annular strip having the outside half circumferences of a circle formed by two main rollers 1 and the almost parallel surfaces connecting both main rollers 1. The flat surface formed by the length and width of the transparent thin plate 2 present between two main rollers 1 becomes the surface of the white or black plate of a copy plate and a back surface plate 3 is arranged so as to be in close contact with the rear of the transparent thin plate 2 opposed to said flat surface. A reading unit 4 is inserted between two opposed main rollers 1 and held between the upper and lower runs of the transparent thin plates 2 forming both front and rear surfaces of the copy plate. A light source 41 irradiates the transparent thin plate 2 with light from the rear thereof and the reflected light from the rear of the image on the front surface of the thin plate 2 is reflected by a reflecting mirror 4 and condensed by a condensing lens 43 to convert light data to charge data by a photoelectric converting unit 44.

The two main rollers 1 are arranged side by side on the inner surface of the outer frame 95 with their rotating axes parallel to each other. The auxiliary roller 91 is located near each of the two main rollers 1, and is located near each of the two main rollers 1.
Tension is applied to the thin plate 92 tightly wound around the outer frame 95 to form a flat surface, and the gap between the outer frame 95 and the thin plate 92 is increased.

That is, when the strip-shaped thin plate 92 wraps around the two rollers 1 to form an annular shape and moves by 10 rotations of the main roller,
The diameter of the main roller l is large in order to increase the rotational force for movement and to reduce bending of the thin plate. The auxiliary roller 91 reduces the annular hollow portion of the thin plate 92 between the main rollers 1 and reduces the depth of the outer frame 95 by the length of the arrow P.

The back plate 93 is in contact with the back surface of the thin plate 92 exposed at the front of the copy board, and forms a flat surface that serves as an underlay when drawing calligraphy by pressing with a pen from the surface of the thin plate 92. The optical unit 94 scans the surface of the thin plate 920 on which the calligraphy is drawn while irradiating it from a light source, collects the reflected light, converts the intensity of the light into the intensity of the charge, and outputs it as electronic information.

As mentioned above, in order to read the image on the surface of the thin plate, conventional copy boards are configured so that an optical unit is disposed on the outside (front side) of the annular thin plate in a gap between the outer frame of the copy board and the opposite surface. Therefore, if there is no auxiliary roller, the depth of the copy board will be the diameter of the main roller plus the depth of the optical unit, and when the auxiliary roller is used, it will come into direct contact with the calligraphy on the surface of the thin board, staining the image, and in the worst case. There was a problem that there was a big risk of it disappearing.

The transparent thin plate moves in a direction perpendicular to the rotation axis of the main roller as the main roller rotates. The back plate is in close contact with the back surface of the plane formed by the transparent thin plate between the two main rollers, and when the transparent thin plate is pressed from the surface of the transparent thin plate, it prevents the transparent thin plate from warping due to this pressing force, and also prevents the surface of the transparent thin plate in contact with the transparent thin plate from warping. Each part has a flat plate shape with a predetermined single color. The image reading unit scans and reads the screen from the back side of the annular transparent thin plate, converts it into electronic information, and outputs it.
