[0002]

2. Description of the Related Art A conventional reading device capable of reading an original by moving an optical reading system has been mainly used in a copying machine, a facsimile device and the like. This reader is CC
Since D is used, the positional relationship of each member such as a mirror and a lens is very rigorously defined, and the surroundings of the housing are generally made of sheet metal.

[0003]

In the above-mentioned reading device, since the reading device made of sheet metal is assembled by sheet metal, it is difficult to assemble it.

That is, when assembling a conventional reader,
Usually, the sheet metal was welded and fixed to each other to form the main body of the device. Then, after the main body of the apparatus was completed, the optical system member, the wire for moving the optical system member, and the like were installed. However, since the housing of the main body of the apparatus is completed, the place where the wire is routed is limited to the inside of the unit, and the work is difficult. Therefore, it is conceivable to connect the wires before forming the device main body, but since the device main body is connected by welding as described above, it has to be performed in a separate step, and as a result, it is necessary to improve the assemblability. Not suitable.

Further, since the optical reading systems are aligned with each other in the reading device, it is necessary to take care not to distort the reading device when the reading device and the apparatus main body are combined. Therefore, the assembling work is made more difficult.

That is, since the reading device for reading an original by moving the conventional optical reading system is a housing made of sheet metal, it is difficult to assemble, and in particular, a wire for moving the optical reading system is used. It has been difficult to install, align the sheet metal forming the housing with each other, and assemble and align the reading device and the main body (for example, a facsimile device).

It is an object of the present invention to realize a reading device and a facsimile device in which a reading optical system moves with good assembling.

[0008]

The present invention uses the following means in order to solve the above-mentioned problems.

A bottom plate provided with a reading optical system, a pair of first side plates provided on the bottom plate and facing each other, and a wire provided on the first side plate for scanning the reading optical system. And a pulley for holding the outer side of the first side plate, and a second side plate that forms a casing together with the first side plate and protects the wire.

Further, it comprises a reading device having an optical reading system such as a reading element and a reflecting mirror, and a fixture for fixing the reading device at three points forming a plane.

[0011]

According to the present invention, the workability is improved because the second side plate is provided after the wire is drawn around the pulley provided on the first side plate according to the above-described structure.

Further, by supporting the reading device at three places, the reading device can be provided in the main body device without distorting the reading device.
