Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a facsimile machine.

[0002]

[Prior art]

 In the conventional facsimile machine, an outer cover is rotatably provided with respect to the main body of the machine for maintenance or replacement of a recording paper roll.

On the surface of the outer cover, an operation portion is provided so as to be offset toward the front so as to be generally easy to operate. Then, for maintenance or replacement of the recording paper roll, the exterior cover is rotated to open the rear of the apparatus body.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional equipment, it is necessary to reserve an installation space other than the operating section in order to open the rear of the equipment body for maintenance and replacement work, which is a problem in terms of space saving, and it is necessary to perform periodical operations. For maintenance and replacement work to be performed, opening the rear of the main body of the device was inconvenient and complicated.

Therefore, as shown in FIG. 8, the support shaft 4 of the exterior cover 3 is placed on the side opposite to the installation portion of the operation portion 1 so that the device body 2 portion (A portion) on the operation portion 1 side is opened. Although it may be possible to provide it, the exterior cover 3 is provided with the operation unit 1 and a reading mechanism unit (not shown) provided in the lower portion of the operation unit 1, and the position of the center of gravity is far from the spindle 4. Will exist.

When the outer cover 3 is opened and closed, as shown in the explanatory view shown in FIG. 9, the component weight W of the outer cover 3 acts on the support shaft 4 in the direction of gravity as a moment. The balance of power is difficult. In the structure shown in FIG. 8, the position of the center of gravity exists in the portion far from the support shaft 4, so that the moment load is further increased. If the open rotation of the outer cover 3 is heavy, on the contrary, acceleration occurs at the time of the close rotation, which causes a sudden rotation, which is a problem.

An object of the present invention is to provide a facsimile apparatus in which the outer cover can be smoothly opened and closed with respect to the apparatus main body, maintenance and replacement work can be easily performed, and space can be saved.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a facsimile machine in which an outer cover having an eccentric operating portion is rotatably supported by a supporting shaft on a main body of the apparatus. The support shaft is installed on the side opposite to the installation part of the operation part so that the main part of the device is opened, and no load is applied when the outer cover is opened and rotated, and load is applied when the outer cover is closed and rotated. It is characterized in that a load means for adding is provided.

Further, a document tray for receiving a document and a sheet discharge tray for receiving discharged sheets are installed on the operation section side independently of the exterior cover.

[0010]

[Action]

 According to the above means, since the spindle of the exterior cover is provided on the side opposite to the installation portion of the operation unit so that the device main body portion on the operation unit side is opened, the momentum for the spindle is increased. In addition, the load during the opening / closing operation of the outer cover is adjusted by the load means, and the opening / closing operation of the outer cover becomes smooth.

Further, by placing the document tray and the paper discharge tray on the operation section side independently of the exterior cover, the opening / closing operation of the exterior cover and both trays do not work together, so the tray is opened / closed when the exterior cover is opened / closed. It does not get in the way, and you can perform various operations on the operation unit, receiving received paper and originals, maintenance, and replacement work all from one direction.
