Description

Description: TECHNICAL FIELD The present invention relates to a display control device.

[Conventional technology]

In the data input of an office computer or a personal computer, qualitative items such as a customer's name, address, and product name are often input. For example, a case where a personal computer or the like is used for inventory management, customer management, or the like. In such a case, it is inefficient to input data one by one with a keyboard.

For this reason, a multi-item input device capable of inputting selection data (items) such as a name, an address, and a product name with a single key touch has been devised. In such an input device, for example, a transparent touch switch is provided on the front surface of a display for displaying input items, and each touch area of the touch switch is configured to correspond one-to-one to an item displayed on a display screen. I have. Then, when the user selects a desired item and touches the selected item, the touch operation is detected, and processing is performed based on the content of the selection data corresponding to the touch area.

[Problems to be solved by the invention]

In the conventional selection data input device, the display area of the items displayed on the display screen is fixed to one screen. For example, when displaying 64 items of selection data, one page is divided into 8 × 8 areas. Each item is assigned to it.
For this reason, the display range of the character string for displaying the selected data is extremely narrow, and it is necessary to display simplified item information. For example, as shown in FIG. 5, when the multi-item display area 6 can display only two characters, even if “AB Shokai” or “AB Shoji” is the full spelling of the selected data, as shown by arrows 7 and 8 Must be abbreviated as "A meeting" and "A thing" respectively. For this reason, the shortened display of the selected data may be similar, and it takes time for the operator to determine the key to be operated, and there is also a risk of erroneous operation.

As described above, when a plurality of items (instruction targets) that can be selected and input by arbitrary instruction selection are displayed, the contents may not be well understood only by the information displayed at the position of the item.

An object of the present invention is to make it possible to display information different from information originally displayed at a display position of a pointing target, as necessary, for a plurality of pointing targets displayed on a display screen. is there.

[Means for solving the problem]

The present invention is a display control device for displaying a plurality of arbitrarily selectable and inputtable targets on a display screen, wherein, for each of the above-mentioned targets, first display information on each of the targets, Information storage means for storing second display information to be temporarily displayed with respect to each of the pointing targets; and displaying the plurality of pointing targets on the display screen, at a display position of each of the pointing targets. First display control means for selecting and displaying the first display information from among the pieces of display information stored corresponding to the individual pointing targets; and displaying the first display information at the display position of each pointing target. When a display position of a desired pointing target is designated on the respective display screens being displayed, the second display information stored corresponding to the pointing target of the designated display position is read, and the reading is performed. The second display information issued Second display control means for displaying the designated target in the display screen for displaying each of the designated targets in association with the display position of the designated designated object; In the state where the second display information is displayed in association with the display position of the designated target in the display screen displaying

And designation means 3 for designating an arbitrary instruction target, and display control means 4 for displaying data stored corresponding to the instruction target by the designation.

〔Example〕

Hereinafter, an embodiment will be described with reference to FIGS. 2 to 4.

FIG. 2 is a system block diagram of a selection data input device according to one embodiment. The multi-item keyboard 9 includes a touch panel in which a transparent touch switch 10 is overlapped on the entire screen of a display unit 10 ′ composed of a liquid crystal display element or the like, a HELP key 11 for instructing a display item to be full-spelled, and its full spelling A HELP release key 12 for releasing the display instruction is provided. The display unit 10 ', the item is a n selection data K ₁ ~K _n is displayed. Transparent electrodes (not shown) are formed in a matrix in a one-to-one correspondence directly above the display position of the selected data on the display unit 10 ', and a finger or the like is pressed at the displayed item position (item key Ti). When touching (touch operation),
The item can be selected. However, the position of the item key Ti is positionally the same as the item Ki (i = 1, 2,..., N) on the display unit 10 'as described above.

The multi-item keyboard 9 is connected to a CPU (central processing unit) 14 via a key data control unit 13. Item key T
When a touch operation is performed on i, a key operation signal is output to the key data control unit 13, and the key data control unit 13 outputs
Is created, and this data is
Output to Also, HELP key 11 or HELP release key 12
Is operated in the same manner as described above.
13 is the corresponding code (HELP on code or HE
LP off code) to the CPU 14.

In addition to the above, the CPU 14 includes a display control unit 15, a display data control unit 16, a display memory 17, a shortened display data buffer 18, an HE
LP key register 19 and full spelling display data buffer
20 are connected. Although not shown, the CPU 14 has a read-only memory (ROM) and a random access memory (RAM).
An access memory is connected, and performs processing described later according to a program stored in the ROM.

When the HELP on-code is input from the key data control unit 13, the CPU 14 outputs a control signal to the HELP key register 19, and sets a flag described later in detail in the HELP key register 19. Further, when the HELP off code is input, the CPU 14 outputs a control signal to the HELP key register 19 and turns off the set flag.

Further, when the item code is input, the CPU 14 outputs a control signal to the display data control unit 16 and notifies the display data control unit 16 that the item key Ti has been operated.

When a control signal notifying the input of the item code is input from the CPU 14, the display data control unit 16 sets the flag to HE.
When it is not set in the LP key register 19, control is performed to read the item data corresponding to the item code input to the CPU 14 from the short display data buffer 18, and when the flag is set in the HELP key register 19, the above item data is read. Control to read from the full spelling display data buffer 20 is performed.

The abbreviated display data buffer 18 stores abbreviated data (data obtained by simplifying the full spelling of the selected data) of the selected data for one screen displayed on the display unit 10 'in advance. The full spell display data buffer 20 stores the full spell item data of each selection data for one screen displayed on the display unit 10 '.

The display memory 17 has a memory area corresponding to the data displayed on the display unit 10 'of the multi-item keyboard 9 in a one-to-one correspondence, and stores shortened data or full spell data of the selected data displayed on the display unit 10'. . That is, the HELP key register
When the flag is not set in 19, the shortened data is written from the shortened display data buffer 18 under the control of the display data control unit 16 described above, and when the flag is set in the HELP key register 19, the display data described above is Under the control of the control unit 16, the full spell display data is written from the full spell display data buffer 20.

The display control unit 15 is configured to read shortened or full spelling data of the item data stored in the display memory 17 based on a display instruction signal of display data output from the CPU 14, and output the read data to the display unit 10 '. is there.

Next, the operation of the selected data input device of the embodiment configured as described above will be described with reference to the flowchart of FIG.

It is assumed that the flag of the HELP key register 19 is reset at the initial stage, and that the display unit 10 'displays the shortened data of the selected data. Display unit 10 'at this time
FIG. 4 (a) shows a part of the display state of FIG. In addition, the abbreviated display A association shown in FIG. 3A is an AB business if fully spelled, and the A business is an AB business.

First, the touch switch 10 or HE of the multi-item keyboard 9
When the operation key input of the LP key 11 and the HELP release key 12 is performed (step (hereinafter referred to as S) 1), the CPU 14 determines the operated key based on the code data converted by the key data control unit 13. . That is, HELP on code or HE
It is determined whether it is an LP off code or an item code (S2). Here, since the abbreviated display of the initial selection data is being performed, it is assumed here that the HELP key 11 has been operated in order to perform the display with full spelling. in this case
The CPU 14 outputs a control signal to the HELP key register 19 to input the HELP on-code to the CUP 14, and outputs the control signal to the HELP key register 19.
Is set to the flag (S3).

Next, similarly, the key input to the multi-item keyboard 9 is determined. For example, if the item key Ti is operated next, the CPU 14
Determines from the item code output from the key data control unit 13 that the operation is the operation of the item key Ti, and determines whether the flag is set in the HELP key register 19 (S2 → S
Four). At this time, since the above-described flag is set in the HELP key register 19, the display data control unit 16 reads out the item data corresponding to the item key code from the full spelling display data buffer 20 and stores it in the memory area of the display memory 17. I do. Further, the CPU 14 outputs a display instruction signal to the display control unit 15, reads out the item data stored in the display memory 17, and displays the item data on the display unit 10 'of the multi-item keyboard 9.
To display the item data (S5). For example, if the item data selected by the key operation at this time is "A company" in FIG. 4A, the full spelling of "A company", "AB company", is enlarged and displayed on the display unit 10 '. . FIG. 6B shows this display state. As described above, the item to be selected is displayed on the multi-item keyboard 9 (display unit 10 ') in full spell and the display area is enlarged, so that the operator can surely confirm that the selected item is correct. .

Next, when the HELP release key 12 is operated, the above processing (S2)
In CPU, the CPU 14 learns that the HELP release key 12 has been operated by inputting the HELP off code, and
And outputs a control signal to reset the flag of the HELP key register 19 (S6). By resetting this flag, the display data control unit 16 reads the shortened data to be displayed in the enlarged display area from the shortened display data buffer 18 and stores it in the display memory 17, and the display memory is controlled by the display control unit 15 to control the display memory. The display data stored in 17 is read out, and the display on the display unit 10 'is returned to the original simplified display of the item data (S7).

In this state, the display control unit 15 displays the reduced display data stored in the display memory 17, so that the display state is as shown in FIG. 4A (S2 → S4 → S8).

As described above, when the item key Ti is operated, the item Ki is displayed in full spelling, and the item data of the item Ki which has been displayed in a simplified form is displayed in full spelling.
The user can easily check the item data, and can quickly and accurately select and input a desired item. Also,
When the enlarged display is not necessary, the original simplified display can be immediately returned by operating the HELP release key 12.

Further, in the above embodiment, the item key is a touch switch, but is not limited to a touch panel, and is not limited to a touch panel. Alternatively, it is also possible to press a key on the keyboard and select an item displayed on the screen.

〔The invention's effect〕

According to the present invention, when a plurality of pointing targets that can be arbitrarily selected and input are displayed on the display screen, the first pointing targets stored in the respective display positions of the plurality of pointing targets corresponding to the respective pointing targets are stored.
By displaying the display information and designating a desired pointing target among the plurality of displayed pointing targets, the second display information stored corresponding to the pointing target is displayed for each of the pointing targets. Since the display is temporarily made to correspond to the designated display position of the designated target on the display screen, the first display information relating to the designated target is displayed at each display position of the plurality of designated targets. On the screen, even if the information may be insufficient with only the first display information displayed at the display position of each pointing target, by specifying the desired pointing target on the display screen, The second display information, which is other display information than the first display information originally displayed with respect to the pointing target, can be immediately confirmed, and the pointing target is selected by the operator. Whether it is desired referent should be, and the contents of the first display information about the referent,
The contents of the second display information that can be temporarily displayed with respect to the pointing target can be immediately confirmed by looking at the display screen displaying the plurality of pointing targets.

A state in which the second display information is temporarily displayed in the display screen displaying the first display information at the display position of each of the pointing targets, in association with the display position of the designated pointing target; Then, when the designation for the designated target is subsequently released, the display of the second display information temporarily displayed in association with the display position of the designated designated target is released. Therefore, when the second display information other than the first display information relating to the designated instruction target becomes unnecessary, the original display screen in which the first display information is displayed on each instruction target by canceling the designation. Can be returned to the display state.
