Abstract

(57) [Summary] [Problem] To provide an inexpensive slide type opening / closing mechanism that does not require a reinforcement of strength of a fulcrum part, a damper for absorbing a shock of a fall, etc. by opening / closing the opening / closing mechanism in a vertical to horizontal direction. SOLUTION: The scanner unit 1 is supported by a plurality of supporting portions by a roller or the like that moves the scanner unit 1 in an opening / closing direction B.
And the load of the scanner unit 1 can be distributed to each support unit. As a result, an inexpensive slide-type opening / closing mechanism that increases the strength of the support portion and does not require a shock absorbing component is realized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide type opening / closing mechanism for opening and closing a moving portion and a fixed portion by sliding in an image forming apparatus.

[0002]

2. Description of the Related Art FIG. 4 is a side view of a digital copying machine having a conventional opening / closing mechanism, and FIG. 5 is a side view of the digital copying machine with the conventional opening / closing mechanism opened. In FIGS. 4 and 5, 1 is a scanner unit that optically reads a document, 2 is a printer unit that outputs the read document, 3 is a rotation fulcrum shaft of the opening / closing mechanism, 4 is a damper that absorbs impact, and A is A. It shows an opening / closing direction which is a vertical direction in the upper and lower directions.

In the conventional example having the above-mentioned structure, FIG.
The scanner unit 1 and the printer unit 2 are connected by a rotation fulcrum shaft 3 as shown in FIG.
It rotates in the up-down opening / closing direction A with the fulcrum as a fulcrum. Since the scanner unit 1 and the printer unit 2 are opened / closed about the rotation fulcrum shaft 3, the damper 4 which absorbs a shock from the upper part of the scanner unit rotating in the opening / closing direction A is located near the rotation fulcrum shaft 3. It is provided in.

[0004]

However, since the opening / closing mechanism having such a structure rotates about one rotation fulcrum shaft, the total load of the scanner unit is applied to the rotation fulcrum shafts of the scanner unit and the printer unit. Will join. by this,
There is a problem in that it is necessary to reinforce the strength of the rotation fulcrum shaft, and since it is opened and closed in the vertical direction, a damper or the like that absorbs the impact of a drop is required from the viewpoint of safety, and the cost is high.

The present invention solves the above-mentioned problems of the prior art. Instead of supporting the load of the scanner section at one fulcrum, a plurality of supporting sections are provided to disperse the load, and the opening / closing mechanism is vertically moved in the vertical direction. It is an object of the present invention to provide an inexpensive slide-type opening / closing mechanism that does not require reinforcement of the strength of a support portion, a damper for absorbing a shock of a drop, and the like for lateral slide opening / closing.

[0006]

In order to achieve this object, a slide type opening / closing mechanism according to the present invention is an image provided with means for optically reading information of a document and means for outputting information to a sheet. The forming apparatus is provided with a means for opening and closing the moving portion and the fixed portion by sliding.

Further, it is means for slidingly opening and closing the moving portion and the fixed portion, and includes a roller portion that rotates, a roller shaft portion that pivotally supports the roller portion and is fixed to the fixed portion, and guides the roller portion. And a rail part fixed to the moving part.

Further, it is means for slidingly opening and closing the moving portion and the fixed portion, and includes a roller portion that rotates and moves, a roller shaft portion that supports the roller portion and is fixed to the moving portion, and guides the roller portion. And a rail portion fixed to the fixing portion.

According to the above construction, the sliding portion can be opened and closed while the moving portion is supported by the roller portion, the roller shaft portion and the rail portion.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a side view of a digital copying machine having a slide type opening / closing mechanism according to Embodiment 1 of the present invention. Here, in each of the following drawings, the same reference numerals are given to those having the same action and effect described in FIGS. 4 and 5 of the conventional example. In FIG. 1, reference numeral 1 is a scanner section that is a moving section, 2 is a printer section that is a fixed section, and B is an opening / closing direction in which the horizontal sliding direction is provided.

As shown in FIG. 1, the slide type opening / closing mechanism is realized at low cost by directly supporting the scanner unit 1 with a roller or the like for moving the scanner unit 1 in the opening / closing direction B. Further, since it is possible to support the scanner unit 1 by supporting the scanner unit 1 at a plurality of positions by rollers or the like, it is possible to disperse the load applied to each supporting unit of the scanner unit 1. Therefore, the conventional opening / closing mechanism shown in FIG. It is not necessary to increase the strength of the supporting portion as compared with Also, by using a slide type opening / closing mechanism, the scanner unit 1 from above
There is no need to worry about falling of the shock absorber, and shock absorbing parts such as the damper 4 (see FIG. 5) are not necessary.

As described above, in the digital copying machine having the scanner section 1 and the printer section 2, the horizontal slide type opening / closing mechanism is different from the conventional vertical opening / closing mechanism having the rotation fulcrum shaft 3 as a fulcrum. Strengthening of support part and damper 4
It can be constructed at low cost without the need for parts such as.

Next, FIG. 2A is a front view of a slide type opening / closing mechanism of the digital copying machine according to the second embodiment, and FIG.
