Embodiment Construction

[0070] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0071] First, the structure will be explained. The following is an example in which the introduction device, paper feeding device, and image forming device of the present invention are applied to a tandem type color laser printer (hereinafter referred to as a printer) in which a plurality of photoreceptors are arranged in parallel.

[0072] Such as figure 1 As shown, the printer 500 includes an image forming unit 200 and a paper supply unit 300 that supplies transfer paper S into the image forming unit 200. The image forming unit 200 includes four image forming units 1 (Y, M, C, Bk) that form images of each color such as yellow (Y), magenta (M), cyan (C), and black (Bk). The imaging unit 1 (Y, M, C, Bk) includes drum-shaped photoreceptors 2 (Y, M, C, Bk), four photoreceptors 2 (Y, M, C, Bk) in the image forming unit 200 In the left and right directions in the figure, they ...

Abstract

The invention provides an attachment assist device, sheet feeder and image forming apparatus, which can accurately determine the location of components and introduce components. An engagement pin (740) and the engagement position 800 of drawing arm 710 on the projection plane of the sheet tray 9C along insertion direction of the sheet feeder (50), the sheet tray (9C) moves from drawing start position in an attachment direction to a drawing completion position, and is disposed inside the area (901) as described above, the drawing force a is generated in the area defined by the points of actionB and C of the two dominant resistive forces b and c in the total resistive force of b,c, d, and e.

Description

Technical field [0001] The present invention relates to an introduction device, a paper feeding device, and an image forming device, and particularly to an introduction device, a paper feeding device and an image forming device including an introduction mechanism for introducing a paper feeding cassette into a main body device. Background technique [0002] An image forming apparatus generally includes a reading section that reads an image of a document placed on a contact glass, an image forming section that forms the image read by the reading section on recording paper, and feeding the recording paper To the paper feed section of the image forming section, the photo-writing device of the image forming section irradiates the surface of the photoreceptor with light to form an electrostatic latent image, and mixes the tone composed of cyan, magenta, yellow, black and other color components. The toner is supplied to the electrostatic latent image formed on the surface of the photor...
