Abstract

PURPOSE:To prevent an erroneous processing by constituting the subject terminal so that a prescribed program is actuated only when plural pieces of keys being in a prescribed position relation are operated simultaneously. CONSTITUTION:The subject terminal is provided with a control means which has plural pieces of keys, and actuates a prescribed processing work, when plural pieces of keys being in a prescribed position relation are operated simultaneously among these keys. A utility program is actuated by depressing a prescribed function key in an input key 7. For instance, when it is desired to use it as an electronic calculator, one of segments 12ak - 12fk is depressed. As a result, a CPU 2 executes a program corresponding to its menus 14h - 14l. In this case, the probability that the keys being in a prescribed position relation are operated simultaneously is low. In such a way, it scarcely occurs that accumulated data is erased erroneously.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hand-held electronic computer terminal (hereinafter referred to as a "handy terminal"), and specifically relates to an improvement of the key manual system.

[Prior Art] Computers are usually equipped with utility functions (programs) such as self-diagnosis. The same goes for handheld terminals; by selecting a utility program using the function keys, etc., you can test each part or make initial revisions.

[Problems to be Solved by the Invention] By the way, these utility programs include programs that erase the entire contents of memory or erase file directories. General electronic computers are operated by relatively experienced people, so there is no chance of accidentally erasing data. However, with handheld terminals whose main purpose is to collect information on-site, the users are sales staff, sales personnel, and product ordering personnel. Most of the people are For this reason, it is possible that by pressing a key blindly or carelessly, these programs will be activated and the stored data will be erased.

[Means for Solving the Problems] Therefore, in the present invention, for example, two keys located in a positional relationship such that they can be touched at the same time when the index finger and middle finger are opened moderately, that is, a plurality of keys located in a predetermined positional relationship. The above-mentioned problem is solved by starting the above-mentioned programs only when they are operated at the same time.

[In other words, no matter how much you touch the keys blindly or carelessly, the probability that the keys in the predetermined positional relationship will be operated at the same time as described above is extremely low; This makes it less likely that stored data will be accidentally deleted.

On the other hand, once such positional relationships are taught, there is little risk of them being forgotten, and there is no risk of making maintenance and inspection work cumbersome. [Examples] Hereinafter, details of the present invention will be explained based on illustrated examples. FIG. 1 shows the structure of a handy terminal l. In the figure 2
is the central processing unit that is the control means, and the read-only memory 3
Alternatively, according to a program stored in the random access memory 4, a predetermined process such as a process according to the present invention or an application program is executed. Hereinafter, the central processing *a will be referred to as "cPU", the read-on memory will be referred to as r, ROMJ, and the random access memory rRAMJ. In the following explanation, even when a name is placed in parentheses, the abbreviation will be used hereinafter.

A liquid crystal display (LCD) 5 displays character information or graphic information supplied from the CPU 2.

Reference numeral 6 denotes a transparent touch panel (touch panel) serving as an input means, which is placed over the LCD 5.

Reference numeral 7 denotes an input key, which also serves as an input means, and consists of numerical and various function keys.

8 is a barcode reader that reads barcodes attached to products and supplies them to the CPU 2. 9 is a buzzer that emits an input confirmation sound, an error notification sound, etc.

10 is an input/output board, which connects a host computer (not shown) and C
It is used for exchanging data with PU2.

11 is a calendar clock, which is backed up by a lithium battery (not shown), and generates year, month, date, hour, minute, and second information.

FIG. 2 shows details of the touch panel 6. A total of 36 key segments l2, 6 in the horizontal direction and 6 in the vertical direction, are arranged on this touch panel 6. In the following explanation, when referring to individual keys, the numeral 12 is followed by the horizontal direction. Position codes a-f and vertical direction codes g-α are given.

In this embodiment, the utility program is started by pressing a predetermined function key (not shown) among the input keys 7. CPU2 is the third one on LCD5.
A menu screen l3 as shown in the figure is displayed. Each menu 14 on this menu screen 13 is displayed on each row g-
It is displayed to match Q. Note that when referring to an individual menu, the reference numeral 14 is appended with the reference numeral gQ for each line.

When the menu screen 13 is displayed, for menus 14h to 1412 other than the utility menu 14g, one of the key segments 12ah to 12fl2 in the line gu where the menus are displayed is pressed with a finger.

For example, if you want to use it as a calculator, segment 12ak
- Press any one of 12fk. This allows the CPU
2 executes a program corresponding to the menus 14h to 14Q.

On the other hand, when selecting the utility menu 14g, the key segments 12ag, 1 at both ends of that row g
Touch 2fg with your fingertips at the same time.

As a result, the CPU 12 executes the utility program and displays the next menu screen 15 shown in FIG.

In this embodiment, an initial setting menu 16 and a self-diagnosis menu 17 are displayed on this menu screen 15.

When a fingertip touches one of the key segments 12ah to 12fh corresponding to the initial setting menu 16, a menu screen 18 shown in FIG. 5 is displayed. Segments 12ah to 12fh, 12 a i - 1 of each line corresponding to the menus 19 (calendar settings), 20 (file initialization), and 21 (backlight) shown here
When a fingertip touches any one of 2 f i, 12aj to 12f, j, the CPU 2 executes the program.

On the menu screen 15 in FIG. 4, select any key segment 12ai=1 corresponding to the self-diagnosis menu 17.
When a fingertip touches 2fi, a menu screen 22 shown in FIG. 6 is displayed. There are nine menus included in this self-diagnosis, and by touching the self-diagnosis menu 23 with a fingertip, the menu screen 22 in FIG. 6 and the menu screen 24 in FIG. 7 are displayed alternately. Therefore, each menu 2 displayed on either menu screen 22 or 24
Any key segment 12ah corresponding to 5 to 33
By touching the fingertip to 12f+2, a desired program can be activated.

In this embodiment, the utility menu 14g
When selecting, the key segments that should be touched at the same time are 1
2ag to 12fg, but for example 12bg to 12fg
Alternatively, the fingertip may be brought into contact with the finger at the same time.

[Effects of the Invention] As described above, in the present invention, a predetermined processing task is started when keys in a predetermined positional relationship are operated at the same time.

Therefore, for things that general users should not perform, such as file initialization, erroneous processing can be prevented by performing the above-mentioned predetermined processing operations, and since it is an easy-to-reassemble method, maintenance can also be done in this way. There is no risk that such things will become troublesome.
