Abstract

The invention provides a device for opening and closing a manuscript pressing plate. The device is capable of correctly adjusting the front-rear position of the manuscript pressing plate and allows a decrease in the number of elements so as to form a simple structure. In the invention, the manuscript pressing plate is assembled and can be opened and closed via the device relative to the body of the office machine. One of the means for adjusting the front-rear position of the manuscript pressing plate allows the adjustment of the assembling position between the manuscript pressing plate and the device in the front-rear direction. The means for adjusting the front-rear position of the manuscript pressing plate is directly arranged on a structural element of the device for assembling the manuscript pressing plate.

Description

technical field [0001] The present invention relates to an original pressing plate opening and closing device in which an original pressing plate used in office machines such as copiers, printing machines, facsimile machines, and scanners can be opened and closed relative to a device body of the office machine, and an original pressing plate opening and closing device having such an original pressing plate. Closed device office machines. Background technique [0002] On the device body of office machines such as copiers, printing machines, facsimile machines, and scanners, the original pressing plate covering the upper surface of the contact glass of the device body can be opened and closed by a pair of original pressing plate opening and closing devices. The rear portion of the upper surface of the body. [0003] The original press plate opening and closing device is a hinge mechanism, which makes the original press plate rotatable on the hinge axis rotation direction, and...
