Abstract

PURPOSE:To easily perform the selection of a key code or the change of a display label by switching the display label which is displayed at a display part provided at the neighborhood of a key switch according to the selection of the key code. CONSTITUTION:When either of three kinds of keys at a change-over switch part 1 is selected, a switching signal corresponding to the key is fetched in a switch control part 2. The control part 2 outputs a code switch signal 3 to a function code generation circuit 4 to switch the code of a function key 24 to a selected key group, and outputs a display switch signal 5 to a liquid crystal circuit 6 to change a display which represents the function of the key 24 to a selected display group respectively. The circuit 4 sets the selected key code group, and when the key 24 is depressed, it outputs the key code to the control part based on a key signal from a key switch part 10. The circuit 6 displays the display group indicated with the signal 5 out of the display group set at a liquid crystal display set part 8 on a liquid crystal display part 7.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a data entry device, and more particularly to a data entry device that can easily change the key code and display label of a key switch.

[Conventional technology]

Conventionally, in this type of data entry device, when a specific key switch has a plurality of key codes, the display label corresponding to the selected key code is switched by converting a note using a motor drive. Alternatively, all selectable key codes were written on the key switch itself or on the display label, and the key codes were converted by pressing the shift key.

[Problem that the invention seeks to solve]

The conventional data entry device described above changes the key code and display label of the key switch using mechanical means or by operating the shift key, so: ■ The types of changes that can be made are limited; ■ The failure rate is low. It has disadvantages such as high reliability, low reliability, large external dimensions, and complicated operation.

In view of the above-mentioned points, an object of the present invention is to provide a data entry device that allows easy selection of key codes and change of display labels.

[Means for solving problems]

The data entry device of the present invention includes a display section provided near a key switch, a display setting means for setting a plurality of display groups to be displayed on the display section, and a key switch for selecting 2,000 key code groups. a control means for switching the display group displayed on the display section to any one of the plurality of display groups set by the display setting means in response to switching of the switching means; has.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of a data entry device according to an embodiment of the present invention. The data entry device of this embodiment is
A changeover switch section 1 consisting of a changeover switch 21 (see Figure 2) for changing over a key code and a display label;
A switching control section 2 receives the switching signal outputted from the changeover switch section 1 and outputs a code switching signal 3 and a display switching signal 5 for instructing to change the key code and display label; A function key code generation circuit 4 that changes the generated key code, a liquid crystal display control circuit 6 that changes the liquid crystal display based on the display switching signal 5, and a liquid crystal display board 22 (second display panel) that displays based on the display signal from the liquid crystal display control circuit 6. 2), a liquid crystal display setting section 8 that can freely set the display contents on the liquid crystal display section 7, a normal key code generation circuit 9, and a normal key 23.
(see FIG. 2) and a key switch section 10 consisting of a function key 24 (see FIG. 2).

FIG. 3 shows an example of setting in the liquid crystal display setting section 8 of a display label displayed on the liquid crystal display board 22 by switching three types of function keys FNCI to FNC3 provided on the changeover switch 21.

Next, the operation of the data entry device of this embodiment configured as described above will be explained.

The changeover switch section 1 has FNCl, FNC2 and FN.
There are three types of keys C3, and when any one of them is selected, a switching signal of a value corresponding to the selected key is taken into the switching control section 2. The switching control unit 2 outputs a code switching signal 3 to the function key code generation circuit 4 in order to change the codes of the 22 function keys 24 to the selected key code group, and also displays a display indicating the function of the function key 24. A display switching signal 5 is output to the liquid crystal display control circuit 6 in order to change to the selected display group.

The function key code generation circuit 4 sets the key code group selected by the code switching signal 3, and when the function key 24 is pressed, the key switch unit 10
A key code is sent to the control unit based on a key signal input from the controller. Further, the normal key code generation circuit 9 sends a key code to the control unit based on a key signal input from the key switch unit 10 when the normal key 23 is pressed.

The liquid crystal display control circuit 6 controls the liquid crystal display section 7 to display the display group instructed by the display switching signal 5 from behind the three types of display groups set in the preliminary liquid crystal display setting section 8. The liquid crystal display section 7 displays any one of the three types of display groups set by the liquid crystal display setting section 8 based on the display signal from the liquid crystal display control circuit 6.

Ru.

Figure 4 (al and (bl) function keys FNC
Examples of the display on the liquid crystal display board 22 when FNC1 and FNC2 are selected are shown. When FNCl is selected, as shown in FIG. 3, preset display groups are displayed as "screen", "defect correction", "evaluation", and so on. When FNC2 is selected, preset display groups are displayed as "3 screens", "actual results", 'planned', etc., as shown in FIG.

〔Effect of the invention〕

As explained above, the present invention automatically changes the key code and display of the key switch by switching the display label displayed on the display unit provided near the key switch in accordance with the selection of the key code of the key switch. It has the effect of changing the label.
