Benefits of technology

[0011]In view of such consideration, the present invention is advantageous in providing a sheet conveyer and an image forming apparatus, of which manufacturing cost can be lowered, and of which height can be reduced effectively.

Problems solved by technology

In the sheet conveyer with the lateral guides movable along with the lifting plate, however, when the lifting plate is uplifted to the approximate position, the lateral guides are also uplifted, and the lateral guides may interfere with other parts in the sheet conveyer.
Therefore, height of the sheet conveyer may not be reduced effectively.

Embodiment Construction

[0027]Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0028]As shown in FIGS. 1-3, an image forming apparatus 3 employs a sheet conveyer 1 according to the embodiment of the present invention. In the present embodiment, a nearer right-hand side appearing in FIG. 1, on which an opening 89 is formed, is referred to as a front side of the image forming apparatus 3. Then, directions concerning the image forming apparatus 3 will be referred to based on a user's position to ordinarily use the image forming apparatus 3 and in accordance with orientation indicated by arrows shown in FIG. 1. That is, for example, the user's left-hand side, when the user faces the front side with the opening 89 of the image forming apparatus 3, is referred to as a left-side face of the image forming apparatus 3. Further, a front-and-rear direction (depth), a right-and-left (widthwise) direction, and an up-and-down (vertical) direction are defin...

Abstract

A sheet conveyer including a body, a conveyer to convey the sheet into a conveyer path formed in the body, a conveyer-supporting frame to support the conveyer, a first placement unit including a lifting plate movable between a separated position and an approximate position, and a lateral guide arranged on the lifting plate to be movable integrally with the lifting plate and slidably along a widthwise direction and configured to restrict a widthwise position of the sheet placed on the lifting plate and, is provided. The conveyer contacts the sheet placed on the first placement unit, when the lifting plate is in the approximate position, and conveys the contacting sheet into the conveyer path. The conveyer-supporting frame is formed to have an interference-avoidable dented section, in which the side guide on the lifting plate placed in the approximate position enters partly to avoid interference with the conveyer-supporting frame.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority from Japanese Patent Application No. 2012-155143, filed on Jul. 11, 2012, the entire subject matter of which is incorporated herein by reference.BACKGROUND[0002]1. Technical Field[0003]An aspect of the present invention relates to a sheet conveyer and an image forming apparatus.[0004]2. Related Art[0005]A sheet conveyer with a sheet cassette for storing sheets therein, is known. The sheet cassette may include a lifting plate, on which the sheets to be conveyed are stacked. The lifting plate may be movable between a separated position, in which the lifting plate is lowered to be separated from a conveyer device, and an approximate position, in which the lifting plate is uplifted to be closer to the conveyer device.[0006]The sheet conveyer may further have a lateral guides, which are slidably movable along a direction of width of the sheets, on the lifting plate. The lateral guides may fix a widthwise positio...
