を示す。 1 to 4 are diagrams showing a handy image reader device according to an embodiment of this invention.
The figure shows a side sectional view, FIG. 2 shows a top view, FIG. 3 shows a front view, and FIG. 4 shows a state in use. 5 and 6 are views showing a conventional example, with FIG. 5 being a perspective view and FIG. 6 being a side view. In the figure, 1 is a document surface, 2 is a housing, 3 is an optical dustproof glass, 5 is a CCD image sensor, 7 is a running roller, 10 is a small double-shaft motor, 11 is a speed reducer, and 12 is an encoder disk. In addition, in the figures, the same reference numerals indicate the same or equivalent parts.

Claims

[Scope of utility model registration request]

In a handy image reader device that contacts the document surface and moves in the sub-scanning direction to read information such as characters or pictures on the document surface with an image sensor section, the movement in the sub-scanning direction is made to be at a constant speed. A traveling roller is rotated on one shaft of a small double-shaft motor via a reducer, and an encoder disk with equally spaced scales is attached to one shaft and rotated, and the rotational output pulses of the encoder disk are photoelectrically converted. When taken out from the container, the width L1 of the running roller is approximately equal to the effective reading width L2 of the image reading contact CCD image sensor.
or a handy image reader device characterized by having dimensions larger than that.
