Abstract

PURPOSE:To obtain a holding cover which is of low cost, easy to assemble, and scarcely causing breakage of glass plate by attaching a magnetic body to each facing part of the glass plate and the cover main body to pressure the glass plate to a supporting part of the glass plate receiver, so that the surfaces of the same polarity are faced. CONSTITUTION:The original to be read or the recording material is placed on the supporting board 11, and the holding cover 12 is lowered on top to pressure it down, the original or the recording material are pressured and fixed to the supporting board 11 at the glass board 14. At this time, even after the glass plate 14 is made to contact the supporting board 11 and not able to be lowered, a cover main body 12 and the glass plate receiver 15 are further lowered, and since the glass plate 14 is made freely slidable against the glass plate receiver 15 through a sliding guide 18, no problem arises. After that, the glass plate 14 is pressured to a supporting board 11 with specified pressure by the repulsive force between the magnetic bodies 17A and 17B, and the original or the recording material is fixed. Thus the assemblying man-hour can be cut down and since the glass plate can be slided even when slanted, breakage of the glass plate can be reduced.

2. Description of the Related Art Document holders used in general copying machines and the like are used to hold down and fix a document placed on a document table glass, and the document is read through the document table glass. For this reason, the original presser only needs to have the function of holding the original, and a sponge or coil spring is arranged behind the original holding surface so that the document can be evenly pressed by the original holding surface (for example, Publication No. 144733 of 1982, Utility Model Publication No. 1987-144733
(See Publication No. 120749).

On the other hand, image input/output devices for newspaper faxes and automatic typesetting systems use a plate glass to hold down the original or recording material.The plate glass holds down the original or recording material, and the document is read or recorded through the plate glass. Is going. Conventionally, a document or recording material holding device used for this type of application has a support base 1 having a flat support surface 1a for supporting the document or recording material, as shown in FIGS. It is equipped with a presser cover 2 for pressing and fixing a document or a recording material on a support stand 1, and the presser cover 2 is attached to a cover body 3 having a large opening 3a formed therein. It is equipped with a flat glass plate 4. To attach this plate glass 4 to the cover main body 3, a support 5 is erected on the lower surface of the cover main body 3, this support 5 is passed through a hole 4a made in the plate glass 4, and the plate glass 4 is dropped onto the lower end of the support 5. A washer 6 for fixing the plate glass is fixed with screws 7 to prevent the glass from being damaged. Furthermore, in order to compensate for the positional accuracy of the hole 4a formed in the plate glass 4, the hole 4a is
A plate glass holding ring 8 is inserted in a, and the plate glass 4 is movable with respect to the column 5 via this plate glass holding ring 8. Further, a coiled glass plate holding spring 9 is inserted between the plate glass holding ring 8 and the cover main body 3. With this configuration, when the presser cover 2 is open, the plate glass 4 is held by the washer 6, and when the presser cover 2 is closed, the plate glass 4 is pressed against the support base 1 by the glass plate presser spring 9, The upper document or recording material (not shown) can be held down, and the lower document or recording material can be optically scanned for reading, recording, etc. through the plate glass.

A recess is formed.

Problems to be Solved by the Invention However, with this configuration, the plate glass becomes expensive and
There were problems in that assembly required a lot of man-hours and the plate glass could be damaged.

The above problem arises for the following reasons. Firstly, holes must be made in the plate glass for the support to pass through, but when drilling holes in the plate glass, glass powder is generated, and this glass powder can cause scratches on the surface of the plate glass during processing. Reeds, small drops get worse. The accuracy of the hole positioning in the plate glass is still poor, and there is still a large error between the pitch of these holes and the pitch of the pillars that have been drilled into the cover body, which also makes the dripping worse. . For this reason, plate glass has become expensive.

Second, in order to attach the plate glass to the cover body, it is a complicated process of first inserting a spring to hold the plate glass into the column supporting the plate glass, then inserting the plate glass into the column, and then attaching the washer to the column with screws. , which was difficult to work with and took a lot of man-hours.

Thirdly, because holes are made in the glass plate and the support is passed through the holes, if originals or recording materials with partially different heights (thicknesses) are placed on the support stand, the glass plate holding it down will be tilted. In some cases, the pillar supporting the glass plate and the glass plate could fit together, causing the glass plate to break.

The present invention has been made in view of the above-mentioned problems, and provides a presser cover that can be attached to the cover body without making holes in the glass plate, is inexpensive, easy to assemble, and is unlikely to cause damage to the glass plate. An object of the present invention is to provide a document or recording material holding device equipped with six pages.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention eliminates the need to make holes in the plate glass, and instead includes a guide part on the back surface of the cover body to guide the side edge of the plate glass. A plate glass holder is provided having a support part that supports the lower surface of the plate glass, and in order to hold the plate glass with the plate glass holder and press the plate glass against the support part of the plate glass holder, the opposing surface of the plate glass and the cover body is provided. The structure is such that a magnetic body is attached to each of the two so that the surfaces of the same polarity face each other.

According to the above-described structure, the present invention has a plate glass holder attached to the cover body that movably holds the plate glass while regulating it so as not to shift laterally, and the cover body can be placed on a support stand on which a document or recording material is placed. By lowering the recording material, the original or 71\-7 can be held down by the plate glass being pushed by the repulsive force acting between the magnetic materials, and the plate glass that passes through the column and the column can be pressed down as in the conventional method. Holes are no longer required, making it possible to significantly reduce costs, and making removal work much simpler.
Assembly man-hours are reduced. Furthermore, since the glass plate can be slid diagonally, breakage of the glass plate is reduced.
