Abstract

(57) [Abstract] [Purpose] The present invention is intended to prevent light leakage when reading a thick original, improve reading quality, and eliminate the need to remove the original holder 17 when the original holder is not used. It is intended. [Structure] A document holder 17 made of a soft material is used, and the document holder 17 is wound and housed in a winding portion 15 of a reading device main body 11.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an image reading device which reads an image by sandwiching a document between a document table and a document holder.

[0002]

[Prior Art]

 FIG. 3 is a schematic perspective view showing an example of a conventional image reading apparatus (scanner). In the figure, reference numeral 1 denotes a reading device main body, and a document table 2 is provided on the reading device main body 1. Reference numeral 3 denotes a document holder whose one side is rotatably attached to the reading apparatus main body 1 and which holds a document (not shown) on the document table 2. The document holder 3 is made of a hard material such as plastic. Is becoming

In such a conventional image reading apparatus, after placing a document on the document table 2, the document retainer 3 is closed, and the document is sandwiched between the document platform 2 and the document retainer 3, and the image of the document is captured. Read. At this time, the document holder 3 prevents light from entering from the outside.

[0004]

[Problems to be solved by the device]

 In the conventional image reading apparatus configured as described above, since the document retainer 3 is made of a hard material, the document retainer 3 must be completely closed when reading a thick document (for example, the page surface of a book). Therefore, there is a problem that the reading quality is deteriorated due to light leakage. Further, when reading a transparent original, it is necessary to remove the original holder 3 from the reading apparatus main body 1, which is troublesome.

The present invention has been made to solve the above-mentioned problems, and it is possible to prevent light leakage when reading a thick original and improve the reading quality. It is another object of the present invention to provide an image reading device that does not require the trouble of removing the document holder when the document holder is not used.

[0006]

[Means for Solving the Problems]

 The image reading apparatus according to the present invention uses a document retainer made of a soft material, and the document retainer can be wound up and housed in the winding unit of the reader body.

[0007]

[Action]

 In this invention, by using a document holder made of a soft material, light leakage is prevented at the time of reading a thick document, and at the time of reading a transparent document, the document holder is taken up and stored in the take-up unit of the reading apparatus main body.

[0008]

【Example】

 An embodiment of this invention will be described below with reference to the drawings. 1 is a sectional view of an image reading apparatus according to an embodiment of the present invention, and FIG. 2 is a perspective view showing the appearance of the image reading apparatus of FIG. In the figure, reference numeral 11 denotes a reading device main body in which an original table 12 is provided, and inside the reading device main body 11, a reading head 13 and a drive motor 14 thereof are provided. Reference numeral 15 is a take-up unit provided at one end of the reading device main body 11, 16 is a take-up shaft provided in the take-up unit 15, and 17 is a document holder provided on the document table 12. The document holder 17 is made of a soft material such as a rubber sheet. The document holder 17 has a base end fixed to the take-up shaft 16 and is wound around the take-up shaft 16 and stored in the take-up unit 15. Further, a handle 17a is attached to the leading end of the document holder 17.

In the image reading apparatus configured as described above, the document holder 17 is normally locked in a pulled-out state as shown in FIG. 1, and the document holder 17 is lifted and placed on the original table 12. A document is placed, and the document is sandwiched between the document table 12 and the document holder 17 to read the image of the document. When the transparent original is read, a storage button (not shown) is pressed to unlock the take-up shaft 16 and rotate the take-up shaft 16 clockwise. As a result, the document holder 17 is wound around the winding shaft 16 and stored in the winding portion 15, as shown in FIG. From this state, when the document holder 17 is to be used again, it is sufficient to hold the handle 17a and pull out the document holder 17 by a necessary amount.

In such an image reading apparatus, since the document holder 17 is made of a soft material, the document holder 17 is easily deformed along the shape of the document when a thick document is read, which causes light leakage. Is prevented and uniform pressing can be realized. Further, when the original document holder 17 is not needed, the original document holder 17 can be easily stored by simply winding it around the take-up shaft 16, so that switching to transparent original document reading can be easily performed, and the workability is improved.

The material of the document pressing member 17 is not limited to the rubber sheet, and other soft material may be used. Further, the winding mechanism of the document pressing member 17 is not particularly limited, and may be a manual one or an automatic one.

[0012]

[Effect of the device]

 As described above, since the image reading device of the present invention uses the document holder made of a soft material, it is possible to prevent light leakage when reading a thick document and improve the reading quality. Play. In addition, when the original is not pressed, such as when reading transparent originals, the original retainer is retracted and stored in the take-up section of the main body of the reading device. It also has the effect.
