Embodiment Construction

[0038] specific implementation

[0039] Embodiments of the present invention will be described below with reference to the drawings. Figure 25 Indicates the plan view of tray 1, Figure 26shows its side view. The paper feeding tray 1 is equipped with a box body 10 , a paper loading plate 20 , a side guide 30 , an end guide 40 , a paper separation claw 50 , a deceleration roller 60 , and a box body plug-in handle 70 . The box body 10 is a box-shaped casing of the paper feeding tray 1, which is composed of a bottom plate and surrounding side wall panels, and is an open box body above. The paper loading plate 20 is a flat tray placed on the bottom plate of the case 10 , has an ascending gradient in the traveling direction of the paper, and has a lifting function for lifting and lowering according to the amount of paper. The side guides 30 limit both sides of the paper in the paper feed tray 1, keep the paper in the middle of the width direction for g...

Abstract

All the constituent members of a tray 1, for example, a side guide 30, a paper separating claw 50, a tray body 10, a drawing handle member 70, a member for regulating an end guide 40, and a holding member for holding a retard roll 60 each have a snap-fit structure. Therefore, the assembling and disassembling of the tray can be easily performed. The tray is formed only from members that enable all the steps of processes of assembling and disassembling the tray to be performed from the same direction without changing the orientation of the tray.

Description

technical field [0001] The present invention relates to a structure of a paper feed tray used in image forming apparatuses such as printers, copiers, facsimile machines, and composite devices thereof. Background technique [0002] The paper feed tray of the image forming apparatus is composed of a box body, a paper loading plate provided on the bottom of the box body to load the paper used, a side guide to limit the side of the paper, an end guide to determine the position of the end of the paper, and each It is composed of structural components such as a paper separation claw, a deceleration roller, and a handle for disassembling and disassembling the box. For a paper feed tray that can hold more than 250 sheets (1 / 2 pack), it is necessary to ensure sufficient rigidity of the paper feed tray itself. Furthermore, even when the paper conveying speed is high, it is necessary to maintain the paper conveying performance and to assemble each structu...
