た。 Conventionally, in reading optical systems, the light receiving element is placed at the mechanical center,
Adjustment is required to match the reading line. In other words, adjustments are made in the X direction to align the light receiving element to the mechanical center, adjustments in the Y and θ directions to align the light receiving element to the center and parallel to the reading line, and adjustments for example to maximize the output of the light receiving element. This includes adjusting the image lens in the Z direction. Here, in order to make each of the above adjustments to the reading optical system,
For example, adjustments were made by placing an adjustment check pattern document at a reading position provided in the document travel path. Conventionally, the check pattern original for adjustment was
It is simply placed at the normal document reading position.
Therefore, the adjustment check pattern original is
When placed at a position shifted from the Y and θ directions,
The disadvantage was that the reading optical system could be misadjusted.

にその一例を示す如く縦じま模様等である。 Therefore, in order to perform the above-mentioned adjustment, an adjustment check pattern is placed at a reading position corresponding to the opening 6 of the document travel path. The above-mentioned check pattern is printed on an adjustment jig 10, and the adjustment jig is provided opposite to the above-mentioned opening 6 in a detachable manner. For the adjustment jig, attach the jig itself to the document guide 1.
Rubber magnets 1 on both ends to hold the
1 is fixed, and a guide pin 12 is provided so that the check pattern coincides with the reading line. In this adjustment jig 10, the document guide 1 is formed of a magnetic member, and a guide hole 13 is bored on the reading line a in correspondence with the guide pin 12. The above-mentioned check pattern is a vertical striped pattern, an example of which is shown in FIG.

In this state, if the guide pin 12 of the adjustment jig 10 is inserted into the guide hole 13 of the document guide 1, the adjustment jig 10 will be moved by the magnetic force of the rubber magnet 11 as shown in FIG.
It is magnetically attracted and held by the document guide. At this time,
By the action of the guide pin 12 and the guide hole 13, the check pattern can be easily arranged parallel to the reading line. Adjustment jig 10
If it is arranged corresponding to the opening 6, adjustments in the X, Y, θ and Z directions can be made, and the read signal can be confirmed using, for example, a synchroscope. After completing the above adjustment, move the adjustment jig 10 to the document guide 1.
All you have to do is remove it and close the back panel 4.

類の調整を可能にすることができる。 Here, since the adjustment jig 10 is held on the document guide 1 by the rubber magnet 11, it can be easily held by magnetic force even when the reading position is not horizontal, and can be applied to any reading position. or,
Although a rubber magnet is used as a means for attaching and detaching with one touch, the present invention is not limited to this, and any similar holding means may be used. Further, the positions of the guide holes 13 of the document guide 1 are shifted from the reading line a, and are provided above and below, respectively.
By printing two types of check patterns corresponding to each guide hole, two types of adjustment can be made with one adjustment jig 10.
