Embodiment

[0044] According to the accompanying drawings, first as figure 1 As shown, on the main body D of the copier A of the present invention, a cover C equipped with an automatic document feeding device c is mounted openable and closable by a pair of cover opening and closing devices B, B'. In the pair of cover opening and closing devices B, B' described above, due to the load applied when the cover opening and closing device B on the left side of the figure performs the opening and closing operation on the heavy mechanism part side of the automatic document feeder c Very big, so in its elastic member (12), adopt the double helical spring mode of two helical springs side by side. On the other hand, since the load on the cover body opening and closing device B' on the right side of the figure is relatively small, although not shown, its elastic member (12) adopts a single coil spring mode composed of a coil spring or uses a torsion spring (torsion spring). However, the structure a...

Abstract

The present invention provides a cover opening and closing device and various machines that can open the cover in the open state without providing a large dead space between the device main body and the back side wall. It has: a mounting member installed on the device main body side The supporting member is rotatably pivotally connected to the mounting member through the first connecting member; the lifting member is pivotally connected to the free end side of the supporting member through the second connecting member, so that it can rotate in the opposite direction to the supporting member; The moving member is arranged at a position that rotates as the lifting member rotates around the second connecting member; and the elastic member is elastically arranged between the actuating member and the supporting member, so that the lifting member is pushed in a direction overlapping with the supporting member, At the same time, the support member is pushed towards the opening direction of the cover; the cover opening and closing device has a bracket member, which pivotally connects the two side plates erected from the installation base installed on the cover side to the free sides of the two side plates of the support member. end side so that it can rotate in a different direction than the lifting member.

Description

technical field [0001] The present invention relates to a cover opening and closing device preferably used for opening and closing the cover of furniture such as a document press board of an office machine such as a copier or a printing machine, or a cabinet, and various devices using the cover opening and closing device. Background technique [0002] Traditionally, especially as a cover opening and closing device for an original press plate opening and closing device used in office machines such as copiers, for example, the cover opening and closing device described in Japanese Patent Application Laid-Open No. 2013-97363 is known. It includes the following members: a mounting member having a mounting base installed on the side of the device main body and two side panels erected from the mounting base; a supporting member having a back panel and two side panels folded from the back panel, and the The two side plates are rotatably pivotally connected to the two side plates of...
