Description

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

[Related Art] In data input of an office computer or a personal computer used as a terminal device such as a seat reservation system or a terminal device such as an inventory management system, a train name, an airline name, a customer name or a product name may be used. There are many routine tasks for inputting fixed items, and it is very inefficient to input characters one by one using ordinary keyboard operations. For this purpose, a multi-item input device has been devised which can input items such as a name and a product name by one key operation (touch operation).

The conventional multi-item input device generally includes an LCD (Liquid Crystal Display) that displays a plurality of items in page units, and a touch panel closely mounted on the display device. By pressing (touching) the upper part on which the item is displayed with a finger or the like, the desired item is input.
Usually, as a usage of the multi-item input device, such a page including a plurality of items has a plurality of pages,
For example, what is used for airline seat reservation is that each page is a page with the name of the airline that operates the U.S. route,
It is divided by airline, such as the page of the name of the airline that operates the European route. In addition, POS (Pint of Sales: point of sale information management) in department stores
In the case of the input device of the terminal device in the system, pages are divided for each product classification, such as a product page for children and a product page for women.

The multi-item input device is generally designed to have versatility for each type of business, and often uses different items (products) for each customer (user). Therefore, not all items in one page are necessarily used.

[Problems to be Solved by the Invention] In other words, since the design is made with a certain degree of versatility, there is a case where an item area that does not need to be input is generated in each page at the user site. In this case, if an unnecessary item is displayed unconditionally, an artificial mistake that an unnecessary item is input easily occurs. To address this,
Processing for determining whether the item input is correct or not is required.
This process is performed every time an item is entered.
And the software processing by the host computer, etc., the load on the host computer etc. increases,
Various problems such as a decrease in system throughput and a slow response to item input have occurred.

This is because when displaying items on each page, unnecessary items are also displayed unconditionally, so it is difficult for the operator to determine that the items are unnecessary, and it is easy for an operator to input errors. Is thought to be the cause.

An object of the present invention is to display only a selected instruction target item when displaying an instruction target item so that useless selection instruction can be prevented beforehand.

Means for Solving the Problems According to the present invention, a storage means for storing a plurality of instruction target items, and arbitrarily selecting an instruction target item to be displayed from the plurality of instruction target items stored in the storage means Selecting means for displaying, and when displaying the plurality of instruction target items, display control means for displaying the instruction target items selected by the selection means and hiding the instruction target items not selected by the selection means And executing a process corresponding to the instruction target item in response to an instruction to select the instruction target item among the plurality of instruction target items selected by the selection means. With respect to an instruction target item that is not selected by the selection means among the items, the instruction to select the instruction target item is invalidated, and a selection instruction to the plurality of instruction target items again is made. And selection control means for controlling to permit

Embodiment An embodiment will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a block diagram showing a system configuration of one embodiment. In the figure, a multi-item input device enclosed by a dashed line is a CPU 11, a key data control device 12, a display memory 13, a display control device 14 connected to the CPU 11, and the key data control device 12 and the display control device. Consists of a multi-item keyboard 16 connected to 14.

The CPU 11 includes a key register 11a and a ROM (not shown), and controls the entire system and transmits and receives data to and from a host computer according to a program stored in the ROM.

The multi-item keyboard 16 includes a display unit 16a including a liquid crystal display (LCD) or the like, and a transparent touch panel 16b attached to the display unit 16a in close contact with the display unit 16a. Display 16a
Contains 64 item data Dij (i = 1 to
8, j = 1 to 8) are displayed. Also, the touch panel 16b
Is composed of a transparent electrode (item key Kij) corresponding to the item data Dij displayed on the display unit 16a on a one-to-one basis. When an arbitrary item key Kij is pressed (touch operation), a display item corresponding to the item key Kij can be selected (input).

The display memory 13 is a RAM (random access memory) that stores item data displayed on the display unit 16a for each page.
Is written under the control of.

The display control device 14 reads the page item display data from the display memory 13 based on the control signal applied from the CPU 11, and displays the items on the display unit 16a in page units.

The key data control device 12 performs a key operation on the item key Ki based on a key operation signal output from the multi-item keyboard 16 and corresponding to the item key Kij on which the touch operation has been performed.
A key code corresponding to j is created, and the created key code is output to the CPU 11.

The host computer 20 is a personal computer,
It is composed of an office computer, etc., and has a keyboard, a CRT display, and the like. This is a feature of the present embodiment. The operator can specify an unnecessary item among the items in the page displayed on the display unit 16a of the multi-item keyboard 16 via the keyboard. . When an unnecessary item is input as described above, the host computer 20 enters a key code corresponding to the unnecessary item,
The data is output to the CPU 11 of the multi-item input device 10 via an interface (not shown). When the key code of the unnecessary item is input from the host computer 20, the CPU 11 stores the key code in a built-in key code register. When an arbitrary item key Kij is touch-operated and a key code corresponding to the touched item key Kij is transmitted from the key data control device 12, the CPU 11 stores the unnecessary key stored in the key register 11a. All key codes corresponding to the items are read, and it is determined whether or not there is a key code of an item for which the key code output from the key data control device 12 is unnecessary.

If it is determined that the key code is for an unnecessary item, it is determined that an input error has been made, and the key code corresponding to the input unnecessary item is not transmitted to the host computer 20. On the other hand, if the key code does not match any of the key codes stored in the key register 11a, the key code is determined to be a valid item key code, and the input key code is transmitted to the host computer 20.

Next, the operation of the embodiment configured as described above will be described with reference to FIG. 2 and FIG.

2A and 2B are diagrams for explaining the operation of the present embodiment.

In the present embodiment, the display unit 16 of the multi-item keyboard 16
When displaying items in page units on a, display memory 13
If all the items of the page stored in the page 16 are valid, the item 1 is displayed on the display unit 16a as shown in FIG.
-1, item 1-2,... Item 3-1, item 3-2,.
... Item 8-1,... Display all valid 64 items including item 8-8. On the other hand, in the page, for example, item 3-3 to item 3-8, item 4-3 to item 4-
8, item 5-3 to item 5-8, item 6-3 to item 6
8, item 7-3 to item 7-8, and item 8-3 to item 8
If -8 is an invalid input item, those items are not displayed as shown in FIG. 2 (b) (in the figure, the rectangular area 21 surrounded by oblique lines is not displayed. Area). It should be noted that the display example shown in FIG. 2B is merely an example, and the display form may be changed according to the unnecessary items.

As described above, for an item whose input is invalid, the item name is not displayed in advance, so that an input error by the operator can be prevented beforehand. Also,
If the user accidentally touches an invalid item key for which no item is displayed, the key code corresponding to the invalid item is output from the touch keyboard 16 to the CPU 11, but the CPU 11 outputs the key code from the multi-item keyboard 16. Is entered, it is checked whether it matches the key codes of all unnecessary items specified by the operator stored in the key register 11a. , Does not output the key code. That is, only key codes of valid items are output to the host computer 20 side. Therefore, the host computer 20 does not need to perform the process of determining whether the received key code is an invalid key code, and can perform the process corresponding to the input key code at a higher speed.

Next, a process for item display and item input for operation of the multi-item keyboard 16 performed by the CPU 11 and the display control device 14 will be described with reference to the flowchart of FIG.

First, when the CPU 11 receives a key code corresponding to an item that does not need to be input on a predetermined page transmitted from the host computer 20 or from an application in response to an operator's keyboard operation or the like (S1), The key code corresponding to
Stored in 11a (S2). Then, the display control device 14 is notified of the items that do not need to be input. Display control device 14
Sets the input unnecessary items in a register (not shown) in the apparatus. The display control device 14 has a CP
When a command for displaying a predetermined page is input from U11, the first display item of the page is read from the display memory 13 (S3). It is determined whether or not the first display item is an item that matches the entry-unnecessary item of the page stored in the register for all the entry-unnecessary items (S4).

If the items do not match, the display item is determined to be an input target item, and the item is displayed at a corresponding position on the display section 16a of the multi-item keyboard 16.
In this case, since this is the first display item, it is displayed at the position of item 1-1 corresponding to the item key K11 shown in FIG. 2A (S5).

On the other hand, if it is determined in step S4 that the item does not need to be input, the display item is not displayed on the display unit 16a of the multi-item keyboard 16.

Subsequent to the above processing S5, it is determined whether or not display processing has been performed for all display items on the page (S6).

Then, if there is an item that has not been displayed on the page, the next display item is read out from the display memory 13 (S7), and the display item is also read in the same manner as the first display item described above. It is determined whether the item does not require input (S4). In this way, for all the items of the page stored in the display memory 13, the processing
Steps S4 to S7 are performed, and only the items that are valid for input are displayed on the display unit 16.
Displayed in a.

For this reason, for example, in FIG.
As shown by, items that do not require input are not displayed. Then, since only the items for which the input is valid are displayed on the display unit 16a, it is possible to prevent the user from accidentally inputting an item that does not need to be input.

As described above, when the display control device 14 has finished displaying the items of one page, the CPU 11 causes the multi-item keyboard 16
Of the item key by a touch operation on the touch panel 16b. Then, when the user performs an input operation by touch operation on an arbitrary item key, the input operation is detected by the touch panel 16b,
A key code corresponding to the input item key that has been input is output to the CPU 11 via the key data control device 12.

The CPU 11 inputs the key code output from the key data control device 12 (S8), and compares the input key code with the key codes of all input unnecessary items stored in the key register 11a. (S9) It is determined whether or not the input key code matches the key code of any of the unnecessary input items (S10).

If the key codes do not match the key codes of all the input unnecessary items, the key code corresponding to the item key input by the touch operation on the touch panel 16a is transmitted to the host computer 20.

On the other hand, in the above process S10, if the input key code matches the key code of any of the unnecessary items stored in the key register 11a, it is determined that the unnecessary item key has been operated by mistake. Then, the process returns to the process S8 again, and waits for input of an item key from the multi-item keyboard 16.

In this way, even if an invalid item key (an item key that does not require input) is touched on the multi-item keyboard 16,
The key code corresponding to the invalid item is not transmitted to the host computer 20, and the key code corresponding to the valid item is transmitted to the host computer 20 only when a valid item key is operated. Therefore, the host computer 20 does not need to perform a process of determining whether or not the transmitted key code is an incorrect item input, and can quickly perform a process corresponding to the received key code. Further, since items that do not need to be input are not displayed, the probability that the user erroneously inputs items that do not need to be input is extremely reduced. Further, the user can easily confirm the input items and can quickly and accurately select and input a desired item. Also, even if a key input operation is performed by mistake on an item key that does not need to be input, the input operation error is not determined by the host computer as in the conventional case, but by the CPU 11 in the multi-item input device 10. Time until the next item can be entered,
It is faster than before, and the man-machine interface is significantly improved.

In the above-described embodiment, the item key is a touch panel. However, the present invention is not limited to the touch panel, and a display device in which display items are displayed in page units and a one-to-one correspondence between items displayed in the display device are provided. The present invention can be easily applied to a keyboard multi-item input device provided with a push-down key corresponding to.

[Effects of the Invention] According to the present invention, when displaying a plurality of instruction target items, a selected instruction target item is displayed, an unselected instruction target item is hidden, and the selected instruction target item is hidden. In the selection instruction for, the process corresponding to the instruction target item is immediately executed, and for the non-selected instruction target item, the selection instruction of the instruction target item is invalidated and the selection instruction for the plurality of instruction target items is permitted again. Since control is performed as much as possible, not only can the user directly grasp the target item that can be selected from among the plurality of target item items but also if the operator erroneously selects and specifies an unselected target item. The selection instruction itself is invalidated, and the selection instruction can be performed again as if the selection instruction itself did not exist. When selecting and instructing a desired instruction target item from among various displayed instruction target items, pay special attention so that an instruction item that is not selected is incorrectly selected and instructed. It is not particularly necessary to pay special attention, such as paying for, and it is only necessary to select and instruct the selected target item again, and the selected target item and the non-selected target item are mixed. The selection instruction operation on the displayed display can be performed satisfactorily.
