Embodiment Construction

[0024] Next, an image forming apparatus according to an embodiment will be described with reference to the drawings.

[0025] figure 1 It is a schematic cross-sectional view showing an example of the overall configuration of the image forming apparatus according to the embodiment. In each of the following figures, unless otherwise specified, the same reference numerals are given to the same or corresponding structures. As a structure corresponding to each other, for example, a structure having a plane-symmetrical shape with respect to an appropriate plane can be mentioned.

[0026] Such as figure 1 As shown, the image forming apparatus 100 of this embodiment includes a control panel 1 , a scanner unit 2 , a printer unit 3 , a sheet supply unit 4 , a transport unit 5 , a manual unit 10 , and a control unit 6 .

[0027] Hereinafter, when referring to the relative position in the image forming apparatus 100 , the X1 direction, X2 direction, Y1 direction, Y2 direction, Z1 direc...

Abstract

Provided is an image forming apparatus capable of reducing an opening around a lifting mechanism when a lifting plate is lifted during manual paper feeding. The image forming apparatus includes a paper tray, an elevating plate, a cam, and a shutter. The paper tray is configured to hold sheets. The elevating plate on the paper tray is arranged to ascend and descend between a descended position and an ascended position higher than the descended position. The cam is movable between a first position and a second position. The shutter includes a shielding portion. The shielding portion is located at a shielding position when the cam moves to the first position. The shielding position is a position that overlaps with a region in a height direction occupied by the cam at the second position. The shielding portion retracts from the shielding position when the cam has moved from the first position to the second position.

Description

technical field [0001] Embodiments of the present invention generally relate to image forming apparatuses. Background technique [0002] The image forming apparatus includes a paper feeding unit such as manual paper feeding. The paper feed unit includes a lift plate that lifts the sheet placed on the paper tray from below to the position of the pickup roller. The lifting plate is sometimes automatically raised and lowered by the lifting mechanism. [0003] Manual paper feeding is arranged outside the image forming apparatus when used. Since the lift mechanism includes a movable part, it is necessary to prevent the user's fingers from entering the opening around the lift mechanism when manual paper feeding is used. [0004] If the size of the paper feeding unit is reduced, the opening around the lift mechanism may become larger when the lift plate is lowered. Contents of the invention [0005] The problem to be solved by the present invention is to provide an image form...
