Abstract

A sheet loading device according to the present invention includes a sheet tray, a lift plate, a restricting portion, and an auxiliary restricting portion. The sheet tray can hold a plurality of sheets. The lift plate is provided below the sheet of the sheet tray, the sheet is loaded on the upper surface, and one end edge of the sheet is pushed upward. The restricting portion is movable to a plurality of preset fixed positions, and is provided opposite to a side edge of the sheet intersecting with one end edge of the sheet, and restricts the position of the sheet in the sheet width direction. The auxiliary restricting member is provided on one end edge side of the restricting portion in a state protruding toward the side edge of the sheet than the restricting portion. When the number of sheets stored in the sheet tray is the first, the auxiliary restricting member restricts the side edges of the sheets pushed up by the lifting plate with the first pressing force, and when the sheets stored in the sheet tray are When the second number of sheets is greater than the first number, the auxiliary restricting member restricts the side edges of the sheets pushed up by the lifting plate with a second pressing force greater than the first pressing force.

Description

technical field [0001] The present invention relates to a sheet loading device and an image forming apparatus including the sheet loading device. Background technique [0002] A sheet loading device having a sheet loading section capable of loading a plurality of sheets and conveying sheets from the sheet loading section is suitably used in, for example, a copying machine, a printer, a facsimile machine, or a digital multifunction machine equipped with the above functions. image forming device. In the image forming apparatus, sheets are conveyed one by one from the sheet loading device to the image forming unit. Then, in the image forming section, an image is formed on the sheet. [0003] Conventionally, in this type of sheet loading apparatus, a sheet loading portion on which sheets are loaded has a cassette structure that can be drawn out from the main body of the image forming apparatus in order to replenish used sheets. The sheet loader includes a pair of guide member...
