Embodiment Construction
[0013] Hereinafter, an embodiment of an opening and closing device for an original pressing plate according to the present invention will be described in detail with reference to the accompanying drawings.
[0014] attached figure 1 Among them, the symbol P is the original pressing plate, which is installed on the device main body M of the copier through the opening and closing device H, and the above-mentioned opening and closing device H is mainly composed of the following components: the installation member 1 installed on the above-mentioned device main body M The supporting arm 3 pivotally arranged on the mounting member 1 through the hinge shaft 2 is rotatably arranged;
[0015] In the above-mentioned support arm 3, the first slider 6 and the second slider 7 are slidably accommodated along its long direction, and a compression coil spring 8 is inserted between the first slider 6 and the second slider 7 at the same time. In the example, the compression coil spring 8 is a...

The invention relates to a closing-opening device of a manuscript pressure strip in copycat, electrograph, scanner or all-in-one machine which is composed of components as follows: an installing component installed in the copycat; a supporting component that is pivoted on the installing component and supports the manuscript pressure strip; a first sliding component and a second sliding component that is sliding contained in the supporting component; a compression helix spring that can insert into the sliding components and endow elastic to direction of the manuscript pressure strip, the compression helix spring has have characteristics that a fluid buffer is set in the compression helix spring, and the buffer is composed of components as follows: a cylinder that installs and fixes a base end on the first sliding component; a cylinder rod sliding installed on the cylinder; and a contact system that is integrated set with the cylinder rod and the front end contacts with the second sliding component; a first fluid chamber formed on one side of the cylinder rod; a second fluid chamber formed on another side of the cylinder rod; a fluid adjusting needle valve that adjusts fluid rate between the first fluid chamber and the second fluid chamber with the cylinder rod moving.
Description
technical field [0001] The present invention relates to an opening and closing device of an original pressing plate in a copying machine, a facsimile machine, a scanner, or these compound machines. Background technique [0002] In the past, the opening and closing device of the original pressing plate is composed of the following components: an installation member installed on the main body of the copier or the like; 1st and 2nd sliders slidably housed inside; inserted into these sliders, at the same time imparting elasticity to the compression coil spring in the direction of opening the above-mentioned original pressing plate, and a fluid buffer is provided between the above-mentioned mounting member and the supporting member The device, so that the supporting member can only be started under a certain closing angle. [0003] However, if Figure 4 As shown in (A), the absorption energy of the above-mentioned fluid buffer is fixed, so it is necessary to prepare buffers with...
