Benefits of technology

[0006]This application relates to a sheet storage cassette including a mark that indicates a maximum storage capacity level of the sheet storage cassette so that an operator of an image forming apparatus can confirm (e.g., determine or refer to) the maximum storage capacity easily.

Problems solved by technology

During use of the printer, if all stored sheets are supplied into the image forming apparatus, an operator of the image forming apparatus supplies a deficiency of sheets.

first embodiment

[0021]FIG. 2 is an explanatory view illustrating a composition of a printer 100 according to a first embodiment. The printer 100 can serve as an image forming apparatus, by creating an image on a sheet P (e.g., of paper or other material suitable for receiving an image) with an electro-photographic technique, based on image data received from an external computer. The printer 100 can include an image forming unit 1, a sheet supplying unit 2, a sheet storage cassette 3, a transfer roller 4, a fusing unit 5, an ejecting unit 6, and a sheet stacker member 7.

[0022]The image forming unit 1 can include an image drum cartridge 8 and an optical unit 12. The sheet supplying unit 2 can include a pick-up roller 15 and a sheet supplying roller 16, and can separate and supply individual sheets P stored in the sheet storage cassette 3 to an image forming unit 1. Also, a carrying roller 28 and a carrying roller 29 can be arranged downstream of the sheet supplying unit 2 in a sheet carrying directi...

second embodiment

[0038]Next, a composition of the sheet storage cassette 3 of a second embodiment will be described. Elements identical to those of the first embodiment will be designated by the same reference numbers, and results based on inclusion of the identical elements will be incorporated herein by reference. FIG. 8 is an enlarged view illustrating an area around a left restriction guide 38 according to the second embodiment. FIG. 9 is an explanatory view illustrating a cross section of the sheet storage cassette 3 along a plane I-I in FIG. 8 according to the second embodiment.

[0039]A planar part 45 that extends along the width direction of the sheet P can be arranged on an upper side of the left restriction guide 38. Also, as shown in FIG. 11 that will be described later, the planar part 45 can be arranged on an upper side of a right restriction guide 39. The planar parts 45 can be formed horizontally on the left and right restriction guides 38 and 39 so as to collectively form a single memb...

Abstract

A sheet storage cassette can include a sheet supporting board and a restriction guide. The sheet supporting board can support at least one sheet thereon. The restriction guide can be arranged on the sheet supporting board and include a sheet holding surface that is substantially perpendicular to the sheet support board. The restriction guide can further include a mark indicated part at an upper side thereof, where the mark indicated part can extend at least partly along a plane that intersects a plane of the holding surface and can indicate a maximum storage capacity level of the sheet storage cassette.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 U.S.C. ยง119 from Japanese Patent Application NO. P 2011-125237, filed on Jun. 3, 2011, the disclosure of which is incorporated herein by reference.BACKGROUND[0002]1. Technical Field[0003]This application relates to a sheet storage cassette and an image forming apparatus that includes the sheet cassette.[0004]2. Description of the Related Art[0005]An image forming apparatus, such as an electro-photographic printer, a fax machine, and a copying machine, includes a sheet storage cassette that stores sheets. A sheet supplying unit of the printer separates and supplies individual sheets stored in the sheet cassette into an image forming unit. Then a process of an image forming onto the sheet is executed in the image forming unit. During use of the printer, if all stored sheets are supplied into the image forming apparatus, an operator of the image forming apparatus supplies a deficiency of sheets. Also,...
