[0002]

2. Description of the Related Art By providing a liquid crystal display section on an operation panel section of a copying machine or the like, a high quality display and a compact panel section can be obtained. Therefore, it has been adopted in many models in recent years. However, due to the limit of the amount of light of the liquid crystal, external light,
For example, the recognizability of the display unit may be impaired by the light of a fluorescent lamp in the room.

[Problems to be Solved by the Invention]

As a means for preventing this, for example, there is a method of adjusting the angle of the entire operation panel section as in the technique disclosed in Japanese Utility Model Laid-Open No. 2-75649. However, according to this method, a complicated adjusting mechanism is required, the size of the apparatus is increased, the cost is increased, and it may be difficult to set the optimum angle.

In view of such conventional problems, the present invention has been made.
It is an object of the present invention to provide an operation panel of a copying machine that realizes light shielding with a simple structure and can obtain excellent operability.

[0005]

According to a first aspect of the present invention, an operation panel for a copying machine according to claim 1 is an operation panel for a copying machine having a liquid crystal display portion protruding above the main body of the apparatus.
A light blocking member for blocking light from above is provided around the liquid crystal display unit.

The operation panel of the copying machine according to claim 2 is
The arrangement angle of the light shielding member is variable.

The operation panel of the copying machine according to claim 3 is
It is characterized in that the light shielding member is detachable from the operation panel main body.

The operation panel of the copying machine according to claim 4 is
It is characterized in that the light shielding member also serves as a protective member for protecting the liquid crystal display section when not in use.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the outer appearance of a copying machine using an embodiment of an operation panel of a copying machine according to the present invention. In the figure, reference numeral 1 is a main body of the apparatus, 2 is a paper feed tray section for stacking transfer sheets and conveying the inside of the main body 1 of the apparatus, and 3 is an ADF section for automatically conveying a copy document. Also, 4
Is an operation panel section, which has a structure protruding above the apparatus main body 1 to improve operability.

FIG. 2 is an enlarged perspective view showing the structure of the operation panel section 4. In the figure, reference numeral 5 denotes a hard key, which is provided with a start key, a ten key, a mode clear key, etc., and is used at the time of setting various modes such as the number of copies and at the start of copying. A liquid crystal display unit 6 has a structure in which a touch panel is provided on the surface of the liquid crystal. The liquid crystal display unit 6 has various detailed mode settings other than those set by the hard key 5,
It is used for various displays such as device abnormality display and device usage guidance display. Reference numeral 7 denotes a light shielding member, which is installed near the upper portion of the liquid crystal display unit 6 and prevents external light such as indoor fluorescent light from being reflected on the surface of the liquid crystal display unit 6 and impairing display quality.

FIG. 3 is a side view showing a second embodiment of the operation panel of the copying machine according to the present invention. In the operation panel unit 4 of the present embodiment, a light shielding member 7 is attached to the main body of the operation panel unit 4 via a hinge 8. If a free stop hinge is used for the hinge 8, the angle of the light shielding member 7 can be set arbitrarily. A fixing screw or the like for fixing the light shielding member 7 after setting the angle may be provided.

FIG. 4 is a partial sectional side view showing a third embodiment of the operation panel of the copying machine according to the present invention. The light-shielding member 7 of the present embodiment is provided with a mounting claw 9, and the mounting claw 9 is inserted and held in the mounting hole 10 provided in the operation panel section 4. With this configuration, the light shielding member 7 can be easily attached to and detached from the operation panel unit 4, and can be removed when unnecessary.

FIG. 5 is a side view showing a fourth embodiment of the operation panel of the copying machine according to the present invention. The light shielding member 7 of the present embodiment can be rotated by a hinge 8 to a position that covers the front surface of the operation panel unit 4. Further, the size is set so that the entire surface of the liquid crystal display unit 6 can be covered during this rotation. As a result, the light shielding member 7 can also serve as a protection member that protects the surface of the liquid crystal display unit 6 when not installed.

[0014]

As described above, the operation panel of the copying machine according to the present invention is provided with the light shielding member for preventing the external light from being reflected on the surface of the liquid crystal display portion and impairing the visibility of the display. Therefore, there is an effect that the original high-quality display quality of the liquid crystal display unit can always be obtained.

In the operation panel of the copying machine according to the second aspect, since the installation angle of the light shielding member can be arbitrarily set, it is possible to select the optimum position according to the use environment condition, and the effect according to the first aspect. There is also an effect that you can always get.

In the operation panel of the copying machine according to the third aspect of the present invention, since the light shielding member is detachable, in addition to the common effects described above, the operation panel can be made compact when it is used under unnecessary conditions. This has the effect that the operability is not impaired.

In the operation panel of the copying machine according to the fourth aspect, the light-shielding member also serves as a protective member for the surface of the liquid crystal display section when not in use. There is an effect that deterioration of the surface due to dirt can be prevented and high-quality display can be maintained.
