SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides an image reading apparatus in which another apparatus can be installed on the upper surface of the main body of the image reading apparatus.

[0010]

An image reading apparatus of the present invention comprises an apparatus main body incorporating the image reading unit and a document placing tray which is put in and taken out from a storage opening provided on a side surface of the main body. The tray is characterized in that the bottom plate has a transparent drawer structure, and the image reading means reads the image of the original document facing the bottom plate of the tray.

[0011]

According to the image reading apparatus of the present invention, the image reading apparatus main body is constructed such that the original is faced to the bottom plate of the original placing tray which is put in and taken out from the storage opening provided on the side surface of the main body, and the image of the original is read. Since the movable part is excluded from the upper surface of the above, another device can be installed on the upper surface of the image reading apparatus main body. Further, since the document cover is configured to press the document from above, an image of a thick document can be read.

FIG. 1 is an external view of an embodiment of the image reading apparatus of the present invention. FIG. 2 is a sectional view taken along the line AA of the device of the present invention in FIG. FIG. 3 is a sectional view taken along line BB of the device of the present invention in FIG.

In FIG. 1, reference numeral 1 is an image reading apparatus main body. Reference numeral 2 denotes a document placing tray, which is put in and taken out from a storage opening provided on the side surface of the image reading apparatus main body 1. Reference numeral 3 denotes an original cover made of deformable rubber, one end of which is fixed and the other end of which is a hook hole 31 on the original cover.
2 is fixed by being fitted into the hooking column 30 of FIG. 2 so that the document 4 facing the bottom surface of the document placing tray 2 does not move. Reference numeral 5 denotes a reading glass, which is a transparent member that constitutes the bottom surface of the document placing tray 2.
Light source 6, mirror 7, reading lens 8, solid-state image sensor 9
The image of the original 4 is read by the normal image reading means configured as follows. The operation of the embodiment of the image reading apparatus of the present invention will be described below with reference to FIG.

As shown in FIG. 1, the document placing tray 2 is pulled out from the image reading apparatus main body 1 in the direction of the arrow b, the document cover 3 is turned over, and the document is placed on the document placing tray 2.
Then, the original cover 3 is lowered again, and the hook hole 31 is hooked on the hook column 30 shown in FIG. At this time, when the original is placed at a more accurate position, the original is placed in the same manner with the original placing tray 2 removed from the image reading apparatus main body 1 and then attached again to the image reading apparatus main body 1. When the document loading tray 2 is inserted into the image reading apparatus main body 1, the document loading tray 2 is fed in the direction of arrow a by a drive system (not shown).

As described above, in the image reading apparatus of the present invention, the original is made to face the bottom plate of the original placing tray 2 which is taken in and out from the storage opening provided on the side surface of the image reading apparatus main body 1, and the image of the original is displayed. As a reading configuration, since the movable portion is excluded from the upper surface of the image reading apparatus body 1, the telephone can be installed on the upper surface of the image reading apparatus body 1. Other than that, a device related to the image reading device, such as a monitor device for monitoring the read image, can be installed without taking up a space. Further, since the document cover 3 presses the document 4 from above, it is possible to read an image of a thick document such as a book.

The specific operation mechanism of the present invention will be described below with reference to FIGS. 2 and 3.

2 and 3 show each roller and the document placing tray 2.
It shows the relationship of.

In FIG. 2, the capstan rollers 16 and 1 are shown.
7 is pressed against the original placing tray 2 by a pressing plate spring 18. By doing this, roller 11 and roller 1
An appropriate frictional force is generated between the document placing tray 2 and the document placing tray 2, and the document placing tray 2 can be moved satisfactorily. Simultaneously with the movement of the document placing tray 2, the light source 6 is turned on to irradiate the document surface through the reading glass 5, the reflected light is guided to the reading lens 8 by the mirror 7, and photoelectrically converted by the solid-state image sensor 9 to generate an image signal. Is taken out as.

In FIG. 3, the roller 12 is rotated by a motor (not shown) via the timing belt 13 and the pulley 14. A friction member 1 is provided on the bottom of the document placing tray 2.
5 is attached, where it is in contact with the roller 12.
Therefore, the rotation of the roller 12 moves the document placing tray 2 in the direction of arrow a in FIG. 1 by the frictional force. The same applies to the roller 11.

FIG. 4 is a sectional view taken along the line AA of the apparatus of the present invention in FIG. 1, showing the case of reading a thick original such as a book.

In FIG. 4, after a thick book is placed on the original placing tray 2, the original cover 3 is attached to the support column 30 as shown in FIG. 4, and the book is pressed against the reading glass 5. This makes it possible to read. The original cover 3 may be deformable, and the material is not limited to rubber.

[0022]

According to the image reading apparatus of the present invention, a document is faced to the bottom plate of the document placing tray which is put in and taken out from the storage opening provided on the side surface of the main body, and the image of the document is read. Since the movable part is eliminated from the upper surface of the apparatus main body, another device can be installed on the upper surface of the image reading apparatus main body. Therefore, a device related to the image reading device such as a monitor device for monitoring the read image can be installed without taking up a space. Further, since the document cover is configured to press the document from above, it is possible to read an image of a thick document and also an image of a book or the like.
