Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an image reading device used in personal computers, word processors, and the like.

Conventional technology The conventional technology will be explained with reference to FIGS. 2 to 5.

Fig. 2 is a perspective view of a conventional image processing device as seen from the top, Fig. 3 is a perspective view of the same as seen from the bottom, Fig. 4 is a perspective view of Fig. 2, and Fig. 5 is a sectional view of the same side. .

According to the figure, 1 is the upper case of the main body, 2 is the lower case of the main body,
3 is a reading sensitivity adjustment knob, and 16 is a cable connected to a word processor or the like. Also, 4 is the main body lower case 2
A roller 6 rotatably supported at both ends of the opening 4 is disposed so as to slightly protrude from the lower surface of the lower case 2 of the main body. Further, a position detecting section is constituted by a disk e having a plurality of equally spaced through holes which rotate in conjunction with the rotation of the roller 5, and an optical sensor 7 disposed at a position sandwiching the through holes of this disk e. There is. A light source 9 is provided near the opening 4, and a reflecting plate 8 is fixed at a position facing the opening 4 at an appropriate angle corresponding to the lens 1o.

A photoelectric conversion element 11 is arranged near the rear focal point of the lens 1o, and this photoelectric conversion element 11 is fixed on a printed wiring board 12.

To explain the operation of the image reading device, the image information on the object to be read 13 is irradiated with the light source 9, and the reflected image information 14 is guided to the lens 10 by the reflection plate 8 and projected onto the photoelectric conversion element 11.

The photoelectric conversion element 11 converts this image information 14 into an electrical signal, which is processed by the printed wiring board 12 and the cable 1
6 to send a signal to a word processor or the like. The above operation is performed by moving the image reading device in the direction indicated by the arrow while rotating the roller 6 to perform desired reading.

Problems to be Solved by the Invention In the above-mentioned conventional technology, a person operates the image reading device using the roller 5, but meandering tends to occur during operation, which may cause distortion in the image. Another problem is that the code 16 comes into contact with the object to be read, making it difficult to perform the reading operation smoothly.

Means for Solving the Problems In order to solve the above problems, the present invention further includes a roller parallel to the roller protruding from the case.

Function: As described above, since a plurality of parallel rollers are provided, meandering is less likely to occur and image reading without distortion is possible, and the movement is smooth.

EXAMPLE Below, an example of the present invention will be explained using a perspective view of the first image processing device seen from the bottom.It should be noted that parts that are the same as those of the prior art are given the same numbers. The case, 2 is a main body lower case, 4 is an opening provided in the main body lower case 2, and is arranged so as to be rotatable with a part protruding from the opening 4. 16 is a cable for sending a signal to the word processor after reading the image;
This is a rear roller that partially protrudes from the lower case 2 of the main body and is rotatable, and is provided parallel to the row 26, similar to the roller shown in FIG.

Effects of the Invention As described above, the present invention has a plurality of parallel rollers protruding from the lower case of the main body, so that meandering is less likely to occur, image reading without distortion is possible, and the image reading device is smooth to operate. This makes it possible to provide the following.

FIG. 4 is a perspective view of FIG. 2, and FIG. 5 is a sectional view of the same side. 1... Main body upper case, 2... Main body lower case, 6°16... Roller.

Claims (1)

[Claims] At least a light source that illuminates the object to be read, a photoelectric conversion element that converts image information reflected by the irradiation into an electrical signal, a case that contains the light source and the photoelectric conversion element, and a part of the case. An image reading device consisting of a plurality of protruding, rotatable rollers that are parallel to each other.
