Problems solved by technology

However, in the hinge described in Patent Document 1, when the support member is opened and closed, the actuating cam portion will apply pressure to the pressure-receiving cam portion, so that the pressing force on the slider will be biased toward the compression screw arranged on the side of the original table. On the spring, it affects the sliding action of the slider, making the slider unable to move smoothly

Embodiment Construction

[0018] Regarding the hinge of the present invention and a photocopier which is one example of office machines using the hinge, the embodiments thereof will be described below with reference to the drawings.

[0019] Such as figure 1 As shown, symbol 1 represents a photocopier which is one example of office machines. According to the drawings, the photocopier 1 includes a device body 2 and a document pressing plate 3 , and the document pressing plate 3 is assembled on the device body 2 through a hinge 10 so as to be openable and closable. The hinge 10 of the present invention is used to connect the original pressing plate 3 to the device body 2 of the photocopier 1 and enable the original pressing plate 3 to be opened and closed. The assembly hole 2b on the 2 side; the support member 7 is assembled to the assembly member 5 via the hinge shaft 6 so as to be rotatable, and supports the original pressing plate 3 . The hinge 10 of the photocopier 1 usually has a pair of left and ...

Abstract

The invention provides a hinge and an office machine using the same. The hinge comprises an assembly part, a supporting part, an actuating cam part, a sliding part and a compression coil spring. The assembly part is arranged on the device body side and is provided with a long box part in the front-back direction; the supporting piece is assembled on the assembling piece through a hinge shaft, can rotate and is assembled with the manuscript pressing plate; the actuating cam part is arranged on the side, facing the assembly part, of the supporting part; the sliding part is in contact with the actuating cam part, is assembled in the box part of the assembly part and can slide, and a pressed cam part is arranged on one side, deviating from the manuscript device table, of the sliding part; more than three compression coil springs are arranged between the sliding part and the inner bottom of the assembly part in an elastic mode.

Description

technical field [0001] The invention relates to a hinge, which is especially suitable for office machines such as small photocopiers, and connects the original pressing plate of such office machines to the device body in an openable and closable manner. Background technique [0002] Known office machines used in offices, such as: photocopiers, compound machines, facsimile machines, scanners, printing machines and other machines, most of them are provided with a manuscript placement table with exposure glass on the device body, and cover the manuscript placement table with There are original pressing plates that can be opened and closed with each other. The original pressing plate makes the original placed on the original placing table close to the original placing table, so as to prevent external light from passing through the exposure glass from affecting the imaging system in the device body. In order to make the original pressing plate assembled on the device body so tha...
