Abstract

A touch key of an operation console includes a circuit board (310) having a light source (312, 314), a light transmitting portion (322) transmitting light, a non-transparent light shielding portion (324) and a semi-transparent operation panel (300) covering upper surfaces of the light transmitting portion and the light shielding portion. The light transmitting portion accommodates the light source. The surfaces of light transmitting portion and light shielding portion in contact with each other are tightly sealed, and the circuit board (310) and the light shielding portion (324) cover the light transmitting portion (322) such that the light is emitted only from the surface in contact with the operation panel (300). Thus, leakage of light from around a figure indicating a touch key can be prevented, and the operation console comes to have a high-class look.

Claims

1. An image forming apparatus comprising:

an operation console, wherein

the operation console includes

a display;

a first touch key displayed in a display area of said display and usable to set a function of said image forming apparatus;

a second touch key including an instruction key usable to instruct display of a basic screen image allowing setting of at least a copy function on said display; and

a third touch key;

said first and second touch keys are capacitance keys;

said third touch key is a mechanical key;

said second and third touch keys are arranged on opposite sides of said first touch key displayed in the display area, with respect to a first direction; and

at least a portion of said third touch key is located outside of an upper longitudinal periphery of the display area of the display in a second direction that is perpendicular to the first direction.

2. The image forming apparatus according to claim 1, wherein

said third touch key is a key that causes transition of said image forming apparatus to a power saving state.

3. The image forming apparatus according to claim 1, wherein said second touch key is located within a width of the display area in the second direction.

4. The image forming apparatus according to claim 1, wherein said operation console further includes a partition that separates said second touch key and said first touch key.

5. The image forming apparatus according to claim 3, wherein

said instruction key is located on an upper side relative to a center of the display area of the display in the second direction.

6. The image forming apparatus according to claim 3, wherein

said second touch key further includes a job status check key that instructs display of job status by said image forming apparatus;

and

said job status check key is located on a lower side relative to a center of the display area of the display in the second direction.

7. The image forming apparatus according to claim 1, wherein said operation console has, on at least a part of an outer circumference of said display area, a color different from the color of a portion adjacent to said third touch key.

8. The image forming apparatus according to claim 1, wherein a portion adjacent to said first touch key, a portion adjacent to said second touch key and a portion adjacent to said third touch key have mutually different colors.

9. The image forming apparatus according to claim 1, wherein said instruction key is a home key to change a screen image displayed on said display to said basic screen image.

10. The image forming apparatus according to claim 1, wherein except for said portion of said third touch key, said third touch key is located inside of the upper longitudinal periphery of the display area of the display in the second direction.
