Abstract

PURPOSE:To easily designate a reading area and to prevent positional aberration from occurring by providing an area designation part which represents the reading area of an original at a fixing part by which an original is fixed at an original cover, and closing the original cover after fixing the original face up. CONSTITUTION:An original fixing body 2 formed inside the original cover 1 mounted at a main body 14 in such a way that it can be opened/closed freely, for example, by impregnating an adhesive in urethane or sponge is provided, and the original 6 is fixed face up. A scale 3 is provided in the periphery of the original fixing body 2, and the length in directions of (x) and (y) of the original 6 are set as xa, xb and ya, yb, and input by a control panel 5 is performed. Thereby, the designation of the reading area can be easily performed, and the positional aberration of the original can be prevented from occurring.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document reading device used in facsimiles, computers, and the like.

[Summary of the Invention] The present invention eliminates the troublesome act of measuring the area to be read using a scale or the like in advance when specifying an area of a document to read in a document reading device, and fixes the document to a document cover. By providing a document fixing section and an area specifying section indicating the reading area of the document fixed to the document fixing section, it is possible to accurately read only a desired area extremely easily and without error.

[Prior Art] In the conventional art, a document is placed with its reading surface in close contact with a document table glass.

For this reason, it is difficult to scan the desired area after placing the original on the original table glass, and it is necessary to determine the reading area in advance using a scale or the like.

[Problem to be solved by the invention 1 In the method of specifying the reading area as described above.

It is necessary to measure the desired area in advance using a scale or the like, which is troublesome. Further, since the reading surface of the document is placed in close contact with the document table glass after measurement, problems such as misalignment and misplacement of the document occur.

[Means for Solving the Problems 1] In order to solve the above-mentioned problems, in the present invention, instead of the conventional method of measuring with a scale, etc., a document fixing section for fixing the document to the document cover, and the document fixing section are provided. An area designation section is provided to indicate a fixed reading area of the document.

[Function] According to the above configuration, since the document can be fixed face up to the document fixing section of the document cover, the area can be easily specified by the area specifying section.

[Example 1 Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a perspective view of a document reading device according to an embodiment of the present invention. In FIG. 1, the document fixing section corresponds to the document fixing body 2, and the area specifying section corresponds to the scale 3.

The document fixing member 2 may be any adhesive and elastic material that can fix the document.For example, it may be made of urethane or sponge impregnated with adhesive. The scale 3 is a known scale for measuring length. The document cover 1 may be of any known type as long as it serves as a weight for blocking light and holding down the document 6.

Figure 2 is a plan view of Figure 1, and using Figure 2,
The operation of the document reading device shown in the figure will be explained.

Place the document fixing body 2 so that the side of the document 6 that you want to read is visible.
According to scale 3, Xl, Xt+ + 3/
a t 3'b is determined and input into the document reading device using the operation panel 5. This makes it possible to read only the desired area.

FIG. 3 is a perspective view of a document reading device according to an embodiment of the present invention.6 In FIG. 3, the document fixing portions correspond to document stops 8a and 8bf, and the area specifying portion corresponds to a scale 7. Document holders 8a and 8b are for fixing the document.
For example, it is a known device made of a magnet or paper clips, and is integrated with the scale 7. Scale 7 is a known one.

Figure 4 is a plan view of Figure 3, and using Figure 4,
The operation of the document reading device shown in the figure will be explained.

Place the original 10 on the original cover 1 so that the side you want to read is visible, fix the original 10 with the original fasteners 8a and 8b, read the desired area with the scale 7, and turn the original reading device on the operation panel 5. to use human power. This makes it possible to read only the desired area. The escape hole 9 prevents the scale 7 from colliding with the document table 14.

FIG. 5 is a perspective view of a document reading device according to an embodiment of the present invention. In FIG. 5, the document fixing section corresponds to an electrostatic adsorbent 11 that uses static electricity to attract the document, and the area specifying section corresponds to an automatic winding sheet 12. For example, the electrostatic adsorption member 11 is a known electrostatic adsorption device consisting of a high voltage generating circuit and an electrode, an electret material, or the like. The automatic winding sheet 12 may be a transparent sheet with an automatic winding mechanism (the sheet is scaled in a grid pattern).

FIG. 6 is a plan view of FIG. 5, and FIG. 7 is a plan view of the document cover 1.
It is an enlarged view of. The operation of the document reading device shown in FIG. 5 will be explained using FIGS. 6 and 7.

Place the original 15 on the electrostatic adsorption member 11 so that the side to be read is visible. Next, as shown in FIG. The coordinates of the desired area are obtained and input into the document reading device using the operation panel 5. This makes it possible to read only the desired area.

[Effect of the invention J As described above, according to the present invention, the original can be fixed face up on the original cover, so there is no need to measure the desired area with a scale or the like in advance, and once the original is fixed, it is not necessary to move it until the reading is completed. Since there is no such thing, problems such as misalignment and misplacement can be solved.
