Abstract

PURPOSE:To improve the input efficiency by showing an address in which a data corresponding to a data displayed on a depressed position has been stored, by a pointer cable corresponding to the depressed position. CONSTITUTION:When (x) and (y) coordinate positions of an LCD panel 3 are depressed, in which part of an application area 40, a generated data is stored is known from a value of a corresponding position of a generated data point cable 8 corresponding thereto, and a character-string is fetched until a delimiter comes therefrom. It is executed in order that the generated data length becomes unlimited, and by one key input, plural character-strings can be generated. If the inputted character-string (generated data) is a code for showing the end of a screen, a display of the next screen and a key cable are set, and if not so, the inputted character-string is delivered as an input data to an application program. In this way, in accordance with necessity, a size of a key can be changed and the input effect can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hand-held data collection device.

[Prior art] In the conventional hand-held data collection device,
Since the display section and the key input section were considered as separate devices, both the display section and the key input section were limited in terms of area.

[Problems to be solved by the invention] The display area is small and the number of characters that can be displayed is small;
Or, because the area of the manual key part is small and all the necessary keys must be assigned,
Each key becomes very small. For these reasons, input efficiency is poor.

The present invention aims to address these problems and provide a device for increasing input efficiency.

SUMMARY OF THE INVENTION The present invention incorporates an apparatus that combines physically and conceptually different devices, such as a key human part and an LCD display part, and can perform both tasks in the same physical area.

With this, when performing input, the user touches the LCD panel with his or her finger while referring to the LCD display, and performs the input. Therefore, a single flow is created in which input is visually prompted and completed by finger touch, increasing input efficiency.

Furthermore, the positions of keys set on the LCD, codes generated, etc. can be freely set using software.

(Operation) In the present invention, the pointer table corresponding to the pressed position indicates the address where data corresponding to the data displayed on the pressed position is stored.

[Example] The details of the present invention will be explained below based on examples.

FIG. 1 is a block diagram of a hand-held data collection device of the present invention. Reference numeral 1 in the figure is a central processing unit that controls the entire system. In the figure, VRAM2, LCD panel 3, touch panel I/F4, LCD controller 5
The LCD panel unit 2C is configured to display characters and detect touch input. Reference numerals 6, 7, and 8 in the figure are the screen display control unit, touch input recognition unit, and touch panel generation data point table, respectively.
A CD panel control section 30 is configured. Reference numerals 9 and 10 in the figure indicate LCD panel display data and key generation data, both of which are stored in the user application area 40.

The operation of the LCD panel control section 30 will be explained below. L.C.
When the (x, y) coordinate position of the D panel 3 is pressed, the location in the application area 40 where the data to be generated is stored is determined from the value of the corresponding position in the generation data point table 8, and the data is stored there. Kara de IJ
Character strings are extracted until the end of the character string is reached (see Figure 2).This is to limit the length of generated data, making it possible to generate multiple character strings using one key manually. If the captured character string (generated data) is a code indicating the end of the screen (can be set arbitrarily by software), display the next screen and set the key table; otherwise, the captured character string is Pass it to the application program as input data. These processes are continued until a code indicating termination (can be set arbitrarily by software) is input.

Screen switching is done using the LC in the application program.
It is determined by the contents of the D display data (first row number 9) and is automatically controlled until the screen data ends.
There is no need to control switching for each screen using an application program.

Also, the number of keyboards that can be set on one screen is, for example, φ
Since it can be set freely within the range of ~7φ, multiple detection points can be combined and set as one key. Therefore, the size of the keys can be changed as needed, making it possible to increase the input effect.

For example, consider a case where the touch panel generation point table of FIG. 18 is set by an application program so that the point tables of detection points a1 to a6 are equal as shown in FIG. 3. No matter which of the six detection points a1 to a6 is pressed, the generated data captured by the touch input recognition unit 7 in Figure 1 points to the middle position of the generated data point table 8 in Figure 1. , the same data will be imported from among the key human power generation data shown in FIG. 10. This results in the detection points a1 to a6 being treated as one detection point.

[Effects of the Invention] As explained above, according to the present invention, in a device in which an LCD display device and a key manual device are combined, keys can be freely set on the same LCD by referring to characters displayed on the LCD. Input can be performed by touching the human power area. Therefore, data input can be performed smoothly, and its effectiveness is particularly demonstrated in miniaturized data collection devices.

Further, since the value of the address in the generated character string point table 8 is adjusted so that a plurality of areas indicate the same address, the size of the key can be made variable as necessary.
