Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an operation panel such as a facsimile machine having a liquid crystal display as a display means.

[0002]

[Prior Art]

 OA equipment such as a facsimile machine is provided with a liquid crystal display as a display means on an operation panel, and various functions can be obtained by combining the function display on the liquid crystal display and the switching operation of operation keys provided on the panel. In many cases, optional functions are selected and executed. FIG. 3 shows a liquid crystal display 2 provided on the operation panel 1 of the facsimile apparatus, and operation keys (3a) arranged around the liquid crystal display 2 and corresponding to the display functions (2a to 2c) of the liquid crystal display 2 to switch each display function. ~ 3c) is shown. According to this example, at the time of transmission, the transmission mode 2a, the stamp 2b, and the original light and shade 2c are displayed on the liquid crystal display 2 as optional functions, and the corresponding operation keys 3a, 3b and / or 3c are switched by a switching operation. , The above three functions are individually switched or adjusted.

[0003]

[Problems to be solved by the device]

 However, in the operation panel 1 of this type, the operation keys (3a to 3c) corresponding to the display are additionally installed on the panel 1 in correspondence with the display functions (2a to 2c) of the liquid crystal display 2, and therefore the illustration is shown. There is a problem that many operation keys are densely arranged around the liquid crystal display 2 together with various other operation keys that are not operated. That is, if there are many operation keys, the appearance of the panel becomes complicated, and it takes time to select the keys and the risk of erroneous operation is amplified.

In order to solve the technical problem, the present invention stores the operation keys for switching the display function of the liquid crystal display in the panel at all times and exposes the operation keys on the panel only when necessary. We propose a hidden button type operation panel.

[0005]

[Means for Solving the Problems]

 In the operation panel based on the present invention, a hidden lid is attached near the liquid crystal display so as to cover the operation keys arranged on the panel and can be opened and closed, and an operation key for switching the display function of the liquid crystal display is provided on the back of the hidden lid. I am trying to provide it.

[0006]

[Action]

 In this way, when the cover is closed, the display-friendly operation keys that are rarely operated are covered by the cover together with the operation keys arranged on the panel, and apparently removed from the top of the panel. To be done. Further, when the hidden lid is opened, the operation keys on the panel covered with the hidden lid and the operation keys corresponding to the display provided on the back surface of the hidden lid are exposed at the same time.

[0007]

【Example】

 1 and 2 show an embodiment of the present invention in comparison with the conventional example of FIG.

In the figure, 1 is an operation panel, 2 is a liquid crystal display (liquid crystal panel) provided on the panel 1, and (3a to 3c) are arranged at positions corresponding to the display functions (2a to 2c) of the liquid crystal display 2. The operation keys (3a to 3c) corresponding to these displays are displayed on the back surface of the hidden lid 7 which is openably and closably mounted on the panel 1 at the lower part of the liquid crystal display 2. It is provided in.

That is, in the lower portion of the liquid crystal display 2, a slightly recessed key storage portion 4 in which operation keys (hidden buttons) 5 and 6 are arranged is formed at the bottom portion, and the upper end portion of the key storage portion 4 is formed. Hidden lids 7 are attached to both sides of the lid by hinges 8 and 8 so as to be openable and closable in the vertical direction. Operation keys (3a to 3c) corresponding to the display are provided.

When the cover 7 is closed, the cover 7 covers the operation keys 5 and 6 in the key storage portion 4 and is fitted substantially flush with the panel surface. On the other hand, when the cover 7 is open, the hinges 8 and 8 are provided. The display operation keys (3a to 3c) provided on the upper portion of the rear surface are rotated about 180 degrees and fall on the panel 1, and the display function (2a to 2c) of the liquid crystal display 2 is respectively provided in that state. ) And the adjacent position.

The operation keys 5 and 6 covered with the hidden lid 7 do not necessarily have to be related to the items displayed on the display 2, but are similar to the operation keys (3a to 3c) and have a relatively low frequency of operation. It is convenient to install the one. In addition, wiring lines connected to the operation keys (3a to 3c) on the hidden lid 7 side are electrically connected to the hinges 8 and 8 at their axial centers. Further, the hidden lid 7 is provided with an opening / closing handle (projection or recess) not shown.

With the above-described configuration, when the cover 7 is closed, as shown in FIG. 2, the operation keys (3a to 3c) corresponding to the display that are operated less frequently are arranged in the key storage unit 4. It is covered with the hidden lid 7 together with the operation keys 5 and 6 that are being operated, and apparently it is removed from above the panel 1. Therefore, in this state, the appearance of the peripheral portion of the liquid crystal display 2 is neatly organized, and the risk of erroneous operation and the convenience of key selection on the operation panel 1 is improved.

Further, when the hidden lid 7 is opened, as shown in FIG. 1, the operation keys 5 and 6 in the key storage portion 4 covered with the hidden lid 7 and the back surface of the hidden lid 7 are provided. The operation keys (3a to 3c) are exposed at the same time. At this time, in the case of the illustrated example, the operation keys (3a to 3c) corresponding to the display can be brought close to the positions directly below the display functions (2a to 2c) of the corresponding liquid crystal display 2.

When the hidden lid 7 is opened, the operation keys 5 and 6 in the key storage 4 and the operation keys (3 a to 3 c) provided on the back surface of the hidden lid 7 both appear on the panel 1. , Both of them can be operated. That is, by using the hidden lid 7, the key layout area on the panel 1 can be substantially doubled. Therefore, the use of the hidden lid 7 can be an effective means for high-density arrangement of operation keys. Then, in the embodiment, if it has such a purpose, the operation keys (3a to 3c) corresponding to the display are removed from the portion between the liquid crystal display 2 and the key storage portion 4, or the hidden lid. It is also possible to add operation keys to the surface of 7.

Regarding the display function (2a to 2c) of the liquid crystal display 2 shown in the embodiment and the arrangement relationship of the hidden lid 7 and the operation keys (3a to 3c) corresponding to the display, of course, there is one. It is only an example.

[0016]

[Effect of the device]

 As described above, in the operation panel of the present invention, a hidden cover is attached near the liquid crystal display to cover the operation keys arranged on the panel so that the cover can be opened and closed. Since it is provided, the hidden lid can be opened to easily switch the operation keys when necessary, while the hidden lid is always closed and the operation keys are stored in the panel, so that the surroundings of the LCD The operation keys are blindfolded to make the appearance simple and improve the convenience of key selection on the operation panel and the risk of erroneous operation.
