Problems solved by technology

Since the adjusting screw protrudes from the spring sleeve, it is easy to rotate the adjusting screw and adjust the position of the spring seat. The spring seat rotates, and with this rotation, the end of the compression spring moves, thereby distorting the compression spring, as a result, the spring force of the compression spring cannot be adjusted to the desired spring force, that is, the torque cannot be adjusted correctly

Abstract

A original manuscript pressing plate opening and closing device is composed of an installation component, a support element, a pair of sliders, a compression spring as well as a spring controlling means, wherein, the installation component is installed at side of the main body; the supporting member can be rotatably installed on the installation components for supporting the original manuscript pressure plate; the pair of sliders can be slidably provided between the supporting member and the installation component; the compression spring is accommodated in the pair of sliders, respectively press the pair of sliders to the supporting member and the installation component, and applies a force to rotate the original manuscript pressure plate toward an opening direction; the spring controlling means is arranged at least one slider side of the pair of sliders, and adjust the spring of the compression spring.

Description

technical field [0001] The present invention relates to a document presser opening and closing device suitable for use in office equipment having a document presser, such as copiers, printing machines, facsimile machines, and scanners, and the office equipment with the document presser. Background technique [0002] On the equipment main body of office equipment such as copiers, printing machines, facsimile machines, scanners, etc., the original press plate is installed on the upper surface rear of the equipment main body in an openable and closable manner via the original press plate opening and closing device. the upper surface of the platen glass. The original platen opening and closing device is a hinge mechanism, which supports the original platen so that the original platen can rotate around the hinge shaft, so that the original platen can be closely attached to the platen glass on the upper surface of the main body of the equipment, and the platen glass can be expose...
