Embodiment Construction

[0037] will refer to Figure 1 to Figure 7B A laser printer 1 is explained as an example of the image forming apparatus according to the embodiment.

[0038] Directions in the following description will be based on the perspective of a user using this laser printer 1 . Specifically, in figure 1, the right side of the laser printer 1 will be referred to as "front side (near side)", the left side will be referred to as "rear side (far side)", the far side will be referred to as "right side", and The proximal side will be referred to as the "left side". Further, the "top" and "bottom" of the laser printer 1 correspond to figure 1 in the vertical direction.

[0039] Such as figure 1 As shown, the laser printer 1 includes a main housing 2 and an additional sheet supply device 10 as an extension unit. An additional sheet supply device 10 can be attached to the bottom part of the main housing 2 so that the additional sheet supply device 10 is located below the main housing 2 . ...

Abstract

An image forming apparatus including: a casing; a first sheet tray provided in a bottom portion of the casing; and configured to form An image forming unit for an image; a sheet supply path; a first conveyance path; and a shutter. The sheet supply path is configured to provide communication between the sheet accommodating portion and the image forming unit. The first conveyance path is provided on one of the housing and the first sheet tray, and has one end formed with an opening opened downward and the other end configured to communicate with the sheet supply path. The shutter is movable between a closed position that closes the first transport path and an open position that opens the first transport path.

Description

technical field [0001] The present invention relates to an image forming apparatus and a sheet supply device provided with a downwardly open sheet conveyance path. Background technique [0002] Japanese Patent Application Publication No. 2012-206840 discloses an image forming apparatus provided with a sheet supply tray below which an additional sheet supply device as an extension unit can be attached. The disclosed apparatus is provided with a sheet supply path for conveying sheets contained in the sheet supply tray, and a sheet conveyance path provided in the sheet supply tray. The sheet supply path opens downward to provide communication with the sheet transport path. Sheets accommodated in the additional sheet supply device can be supplied to the sheet supply path through the sheet conveyance path. [0003] According to the disclosed image forming apparatus, when no additional sheet supply device is attached, the sheet supply path is opened. Therefore, noise generated ...
