Embodiment 1

[0051] Embodiment one. Figure 1 to Figure 7 It is a diagram showing an example of an office machine using the document presser opening and closing device according to the first embodiment of the present invention and an office machine using the document presser opening and closing device. The original pressing plate opening and closing device 1 of the present invention is a kind of hinge device, and the original pressing plate 3 is installed on the top of the device body 2 of office machines such as photocopiers, printing machines, facsimile machines, scanning machines.

[0052] The document press plate opening and closing device 1 of the present invention, as shown in the figure, includes: a mounting member 4 installed on the device body 2; The side plates 42, 42; and the lifting member 6 are installed on the original pressing plate 3 in a state of being rotatably connected to the two side plates 52, 52 of the support member 5 via the second hinge shaft 12; During normal us...

Embodiment 2

[0077] Embodiment two. Figure 8 It shows the second embodiment of the document presser device of the present invention. The difference between the document pressing plate opening and closing device 1A of the second embodiment and the document pressing plate device 1 of the first embodiment is that the anti-pinch anti-hand portion 73 of the anti-pinch mechanism 7 of the second embodiment includes not only the first connecting portion 73e , including the shape adjustment connecting portion 73g. Since the other constituent elements are the same as those of the first embodiment, they are given the same symbols as those in the first embodiment, and their descriptions are omitted.

[0078] The connection part 73g for shape adjustment, instead of a part of the first connection part 73e, or the second connection part 74 or the third connection part 75, is used to connect the plate part 73a and the first mounting part 71 or the second mounting part 72, and the second mounting part 72...

Embodiment 3

[0079] Embodiment three. Figure 9 to Figure 15 It shows the third embodiment of the opening and closing device of the original pressing plate of the present invention. The difference between the original pressing plate opening and closing device 1B of the third embodiment and the original pressing plate devices 1 and 1A of the first and second embodiments is that the hand clamping mechanism 8 of the original pressing plate opening and closing device 1B of the third embodiment , the bamboo curtain-like anti-pinch hand part of embodiment one or two is constituted with a plate-like plate member 85. Since the configuration other than the plate member 85 and the swing support portion 81 of the hand-pinch prevention mechanism 8 is the same as that of the first and second embodiments, the same reference numerals are assigned and description thereof will be omitted. In addition, the support member 5 omits the mounting piece 53 shown in the first and second embodiments.

Abstract

Provided are a manuscript pressing plate opening and closing device and an office machine including the same, which can prevent fingers from being caught in the space between a lifting member and a supporting member and being injured. The manuscript pressing plate opening and closing device 1 includes: a mounting member 4, which is installed on the device body 2 side of the office machine having amanuscript pressing plate 3; a supporting member 5, which is rotatably pivotally supported on the mounting member 4 via a first hinge shaft 11; and a lifting member 6, which overlaps the supporting member 5, is pivotally supported on the free end side of the supporting member 5 via a second hinge shaft 12 in a direction opposite to the supporting member 5, and is installed on the manuscript pressing plate 3, wherein in order to block the space formed between the lifting member 6 and the supporting member 5 when the lifting member 6 rotates in the opposite direction to the supporting member 5,an anti-pinching mechanism 7 is arranged between the lifting member 6 and the supporting member 5 or the mounting member 4 or the first hinge shaft 11.

Description

technical field [0001] The invention relates to an original pressing board opening and closing device contained in office machines such as photocopiers, composite machines, printing machines, facsimile machines, and scanning machines, and an office machine including the original pressing board opening and closing device. Background technique [0002] For the device body of office machines such as photocopiers, printing machines, facsimile machines, and scanners, the original pressing plate is rotatably installed on the upper rear portion of the device body via the original pressing plate opening and closing device. The original pressing plate opening and closing device is a hinge mechanism, which pivotally supports the original pressing plate around the hinge shaft, so that the original pressing plate can be in close contact with the upper contact glass surface of the device body, and at the same time make the contact glass can be exposed. When placing the original on the c...
