Problems solved by technology

[0005] However, since the paper feeding cassette provided with the above-mentioned two-color LED needs to provide the two-color LED and a control unit for controlling its driving, there is a problem that the structure and control become complicated.
In addition, when the power of the main body of the device is turned off, there is a problem that the presence or absence of paper cannot be checked from the outside.
[0006] In addition, in the paper feeding tray with a viewing window on the front, if the paper feeding tray and the paper are both white, there is a problem that it is difficult to distinguish whether there is paper or not.

no. 1 approach

[0034] refer to Figure 1 to Figure 6 The image forming apparatus 1 including the sheet feeding cassette 2 according to the first embodiment of the present invention will be described. Such as figure 1 As shown, the image forming apparatus 1 includes an apparatus main body 3 having a substantially hexahedral structure. The front part of the device main body 3 facing the user is provided with a front cover 4 and a sheet feeding cassette 2. The front cover 4 is installed in a manner that can be opened and closed relative to the device main body 3. By opening the front cover 4, it can be manually The paper feeding cassette 2 can be attached to and detached from the main body 3 of the device. The upper part of the apparatus main body 3 is provided with a discharge tray 6 for discharging paper and an operation unit 7 composed of a plurality of buttons and the like.

[0035] The inside of the apparatus main body 3 is provided with an image forming unit, a fixing unit, a paper fee...

Embodiment 1

[0054] A paper feeding cassette 2 that is entirely white is prepared, and paper having a Munsell value brightness difference (less than) 3.5 from that of the bottom portion 11 is pasted in the area R2 of the storage area 10 a. Other configurations of Example 1 are the same as those of the above-mentioned embodiment.

Embodiment 2

[0056] In the region R2 of the storage region 10a, paper having a brightness difference (less than) 3.0 in Munsell value compared with the bottom surface portion 11 is pasted. Other configurations of the second embodiment are the same as those of the first embodiment.

Abstract

The invention provdes a sheet feeding cassette and an image forming apparatus including the same. The sheet feeding cassette includes a storage region, a front portion, and a bottom portion. On the storage region, a sheet is stored. The front portion is disposed on a downstream side with respect to the storage region in a drawing direction. On the bottom portion, the sheet is placed. In the front portion, an opening is formed through which the storage region is visible. Within the storage region, the bottom portion is formed in white or a pale color. At least a part of the visible region in the storage region is formed to be different in lightness by three or more in Munsell value from a light-color part of the bottom portion, the light-color part being formed in white or the pale color.

Description

technical field [0001] The present invention relates to a paper feeding cassette for storing paper used in image forming apparatuses such as digital copiers and laser printers, and an image forming apparatus including the paper feeding cassette. Background technique [0002] Conventionally, a paper feed cassette that stores and stacks a plurality of sheets of sheet-like paper and supplies the paper to an image forming portion of an image forming apparatus main body according to an image forming operation has been widely used. [0003] For example, an image forming apparatus configured such that a window is provided on the front portion of the paper feeding cassette, and a two-color LED is provided in the main body of the device, and the two-color LED can be confirmed from the window of the paper feeding cassette when the paper feeding cassette is installed in the main body of the device is public knowledge. In this image forming apparatus, since the two-color LED emits yell...
