Operation panel having flexible display

Abstract

An operation panel capable of being effectively reduced in size while the operability and the visibility are maintained at the conventional level. The operation panel includes a flexible display, a plurality of operation keys and a storing part for storing the flexible display in a wound state. In a second operation mode of the operation panel, the flexible display may be withdrawn to a second position at which the flexible display covers a second operation key, in order to enlarge a display area of the operation panel.

Claims

1. An operation panel provided with a display area and a key operation area including first and second operation keys, the operation panel having a first operation mode in which both the first and second operation keys are used and a second operation mode in which the second operation key is not used, wherein the operation panel has a flexible display configured to be moved between first and second positions, the flexible display being positioned at the first position in the first operation mode such that the flexible display do not cover the first and second operation keys, and the flexible display being positioned at the second position in the second operation mode such that the flexible display covers the second operation keys.

2. The operation panel as set forth in claim 1, further comprising a means for changing the position of the flexible display corresponding to the position of the second operation key.

3. The operation panel as set forth in claim 1, further comprising a means for disabling the second operation key, covered by the flexible display, in the second operation mode.

4. The operation panel as set forth in claim 1, wherein the key operation area further includes a third operation key positioned between the first and second operation keys and the operation panel further has a third operation mode in which only the first operation key is used, and wherein the flexible display is positioned at a third position between the first and second position, in the third operation mode, such that the flexible display covers the second and third operation keys.

5. The operation panel as set forth in claim 4, further comprising a means for changing the position of the flexible display corresponding to the position of the third operation key.

6. The operation panel as set forth in claim 4, further comprising a means for disabling the third operation key, covered by the flexible display, in the third operation mode.
