Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information communication apparatus of a type using an optical unit integrally accommodating an optical system for optically reading a document on a conveying path.

[0002]

2. Description of the Related Art Conventionally, in order to simplify the assembly and adjustment of an optical system provided in an information communication apparatus for reading an image, a light source, a mirror, an imaging lens, a photoelectric conversion element, etc., which compose the optical system, are previously stored in a case. An optical unit that is stored and unitized is used. This optical unit was fixed to the bottom surface of the housing by screwing at a plurality of locations (usually four locations). Further, the reading guide arranged above the optical unit so as to guide the document passing on the reading line of the optical unit is attached to a member attached to the bottom surface of the housing.

[0003]

However, since the bottom surface of the device of the housing is usually distorted, if a plurality of optical units are fixed to the bottom surface of the device by screwing, the optical unit is also fixed. There is a problem that distortion occurs, which requires adjustment when mounting the optical unit, which makes work difficult. In addition, as a procedure for assembling this optical unit, it may be necessary to first fix the optical unit to the bottom of the device and then connect the optical unit and other members with a harness, but there is a work space inside the device. Since the number is small, it is extremely difficult to connect the fixed optical unit and another member with a harness, and at that time, there is a problem that the position of the previously adjusted optical unit may be misaligned.

Further, accuracy is required for the distance between the reading line of the optical unit and the reading guide, but in the past, this accuracy was calculated as the positional accuracy between the bottom surface of the device and the optical unit, and the bottom surface of the device and the reading guide. However, it was difficult to maintain the accuracy of the assembly.

The present invention has been made in view of the above-mentioned problems, and does not cause distortion in the optical unit when mounting the optical unit, and therefore, adjustment at the time of mounting is unnecessary and assembly work is extremely difficult. An object is to provide an information communication device that can be easily performed.

Another object of the present invention is to provide an information communication device which is easy to assemble and which can accurately assemble the interval between the reading line and the reading guide of the optical unit.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention has a side surface of an optical unit so that the optical unit can rotate about an axis parallel to a reading line of the optical unit. In order to hold the optical unit rotatably by a support shaft member attached to a side plate attached to the bottom surface of the device and to prevent the optical unit from rotating, one location apart from the rotation axis of the optical unit is provided in the housing. It is provided with a structure in which it is restrained by a supporting member.

Here, it is preferable that the side surface of the reading guide disposed above the reading line of the optical unit is held by a second support shaft member attached to the side plate. In this case, it is preferable that the support shaft member that holds the optical unit and the support shaft member that holds the reading guide are formed as members having an integral structure. Further, it is preferable that the reading guide is rotatably held by the second support member.

Further, the side surface of the optical unit and the side surface of the reading guide may be rotatably held by a common support shaft member attached to the side plate.

[0010]

According to the present invention, since the optical unit is rotatably held by the support shaft member and only one position apart from the rotation axis is constrained by the support member so as not to rotate due to the above-described structure. , The optical unit is not subjected to excessive force as in the case of screwing multiple points, and therefore, when the optical unit is installed in the device, the optical unit is not distorted, so that adjustment work is unnecessary and assembly is possible. Will be easier. Further, by holding the optical unit on the side plate via the support shaft member, the reading line can be accurately positioned at a predetermined position with respect to the side plate. At this time, if the support shaft member rotatably holds the vicinity of the reading line of the optical unit, there is a slight error in the restraint position by the support member that prevents the optical unit from rotating, and the mounting angle of the optical unit Even if some error occurs, the error in the position of the reading line is small, so that the position of the reading line can be accurately positioned.

If the reading guide arranged above the reading line of the optical unit is held by the second support shaft member attached to the side plate, both the optical unit and the reading guide are based on the side plate. It is positioned so that the spacing between the reading line of the optical unit and the reading guide can be accurately assembled.

Further, if the support shaft member for holding the optical unit and the support shaft member for holding the reading guide are made as a member having an integral structure, the distance between the reading line of the optical unit and the reading guide becomes smaller. It depends on the processing accuracy, and the accuracy of the distance between the reading line and the reading guide can be further improved.

Further, when the reading guide is rotatably held by the support shaft member, the support shaft member serves as a rotation fulcrum when the reading guide is opened / closed for jam removal or the like, and the number of parts is increased accordingly. Can be reduced.

Further, when the side surface of the optical unit and the side surface of the reading guide are held by a common support shaft member attached to the side plate, the accuracy of the distance between the reading line of the optical unit and the reading guide is further improved. It is possible and the mounting work becomes easy.
