Embodiment Construction

[0037] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] FIG. 1 shows an image forming apparatus (printer) 100 to which an opening and closing unit opening and closing mechanism according to an embodiment of the present invention is applied. As shown in the figure, an image forming apparatus 100 is provided with a photoreceptor 101 as an image carrier. A charging device 111, an exposure unit 112, a developing device (developing roller) 113, a transfer device (transfer bias roller) 102, a cleaning device (cleaning blade) 115, and a discharge lamp (not shown) are disposed around the photoreceptor 101. ). The charging device 111 applies a voltage through a charging roller or the like to charge the photoreceptor 101 to charge the surface of the photoreceptor 101; , forming an electrostatic latent image on the surface of the photoreceptor 101; the above-mentioned developing device 113 supplies the toner to...

Abstract

A door open / close switch mechanism, which turns on and off predetermined power of an image forming apparatus in conjunction with an open / close operation of an open / close portion of the image forming apparatus, includes an operating member, a switch and an on / off member. The operating member moves in a first direction when a first open / close portion of the image forming apparatus is opened / closed while the operating member moves in a second direction when a second open / close portion of the image forming apparatus is opened / closed. The switch is provided to turn on and off the predetermined power of the image forming apparatus. The on / off member is integrally provided with the operating member and turns the switch on only when the on / off member moves to a predetermined position after moved in both the first and second directions.

Description

technical field [0001] The present invention relates to an opening / closing unit opening and closing mechanism of image forming apparatuses such as copiers and printers. Background technique [0002] Generally, in image forming apparatuses such as copiers, printers, and facsimiles, several opening and closing parts, such as doors, are sometimes provided on the main body of the apparatus in order to replace toner containers or deal with paper jams. In such an image forming apparatus, the image forming operation must be performed only when all the opening and closing parts are in the closed state. In addition, it is necessary to provide an opening and closing detection device for the opening and closing parts so that even if only one opening and closing part is in the open state, the image forming operation cannot be performed. An image forming operation is performed. [0003] In addition, in general, image forming apparatuses are often equipped with vario...
