2. Description of the Related Art Conventionally, as a touch panel type input device, for example, there is one disclosed in Japanese Patent Laid-Open No. 61-228916, which has a display for displaying characters and figures and a front face of the display. It is provided with a transparent touch panel that is arranged and detects the coordinates of the pressed portion, a screen switching keyboard that performs operations such as switching the display contents of the display device, and a function keyboard that includes a group of function keys.

In such a touch panel type input device, even if the touch panel is pressed during the input operation, the touch panel itself does not give a click feeling, and therefore the operator recognizes whether or not the input has been made. It's hard to do. Therefore, in the conventional touch panel type input device, when the input item displayed on the display is pressed, the display color of the pressed item is reversed so that the operator can recognize the input. There is.

In a normal touch panel type input device, a plurality of input items are displayed, and an operator selects and presses a specific item from among the input items. In order to make it easier for the operator to select an item, similar items are displayed in the same color and are color-coded from other types of items.

[0005]

However, in the above-mentioned conventional touch panel type input device, when the reversed color of the pressed input item and the display color of another type of input item adjacent thereto are the same color, the pressed color is depressed. There is a problem that it is difficult to distinguish input items from other types of adjacent items, and it is rather difficult to recognize the input.

[0006]

In order to solve the above problems, the present invention provides a display for displaying a data input item screen,
In a touch panel type input device having a touch panel provided on the front surface of the display for detecting coordinates of a pressed portion, and having a function of changing a display color of a pressed input item,
A storage means for storing the display color of the input item is provided, the display color corresponding to the input item pressed when the input item is pressed is read from the storage means, and the display color before the pressing is read. It is characterized by changing to.

[0007]

According to the present invention having the above structure, when the operator presses the touch panel, the display color corresponding to the pressed input item is read from the storage means. The display color to be read is preset to a color different from the display color of the input item adjacent to the pressed input item. By displaying the pressed input item in the read display color, A press reverse color different from the display color of the input item can be obtained.

Embodiments of the present invention will be described below with reference to the drawings. Note that elements common to the drawings are given the same reference numerals. FIG. 1 is a block diagram showing a touch panel input device of an embodiment according to the present invention, and FIG. 2 is an external perspective view of the touch panel input device of the embodiment.

In FIG. 2, the touch panel type input device is a display 1 for displaying characters, figures, etc., a transparent touch panel 2 arranged on the front surface of the display 1 for detecting the coordinates of a pressed portion, and a display of the display 1. It is composed of a screen switching keyboard 3 for performing operations such as switching of contents, and a function keyboard 4 having a function key group, so that data can be input while looking at the display screen of the display 1 from the touch panel 2. .

In FIG. 1, the display 1 has a display data storage means 6 selected by the display data selection means 9 from the first to Nth display data storage means 10-1 to 10-N.
It is driven by the display drive means 5 on the basis of the above data. Further, the selection data of the display data selecting means 9 is the screen switching key detecting means 7 and the display screen number. It is given through the generation means 8. When the screen switching keyboard 3 is pressed, the screen switching key detecting means 7, the display screen No. It is processed by the generation means 8 and the display data selection means 9, and the display screen No. It is stored in the storage means 14 and output to the input data generation means 13.

On the other hand, the operation signal of the function keyboard 4 is output to the sending data output means 15 via the function key detecting means 16 and the key code generating means 17, and further from the sending data output means 15 to a higher-level device (not shown). Sent to.

The touch on the touch panel 2 is detected by the touch panel data detecting means 11 and converted into coordinate data by the input coordinate generating means 12. Then, the input data generation means 13 generates data in which the display screen data from the display screen storage means 14 is added to this coordinate data, and the data is sent to the transmission data output means 15.

A pressed color definition data storage means 18 is connected to the input data generation means 13, and the input data generation means 1 is connected.
3 from the pressed color definition data storage means 18 to the coordinate data and the display screen No. Data is sent. The pressed color definition data storage unit 18 stores pressed color definition data for each screen in advance, and the sent coordinate data and the display screen number. Based on the data, the corresponding pressed color definition data is read out and sent to the display drive means 5.

Next, the operation of this embodiment will be described with reference to FIG. FIG. 3 is an explanatory diagram showing a display screen for explaining the operation of the embodiment. In the figure, a plurality of input items (station name here) 20 are displayed on the display screen 1 a of the display 1. These input items 20 are color-coded into five areas A, B, C, D, and E according to the degree of similarity. That is, the display color of area A = "0", the display color of area B = "15", the display color of area C = "7", the area D
Display color = “1” and display color of area E = “2”. The color-coded display in this way makes it easier for the operator to select an input item.

The pressed color definition data storage means 18 stores pressed reverse colors corresponding to the screen currently displayed. For example, "3" is defined as this press reverse color.

Now, if the item in area A is pressed, the coordinate data of the pressed position and the display screen number. The data is sent to the pressed color definition data storage means 18 via the input data generation means 13, and "3" as the pressed reverse color is read from the pressed color definition data storage means 18 based on these data. This data "3" is sent to the display driving means 5, and the display driving means 5 inverts the display color of the area A based on this data. As a result, the items in area A are displayed in a color that is not found in other areas of this display screen 1a.

In the above example, the pressed reverse color of the item in area A is defined as a color that is not used for any item on the display screen. Area B is different from the adjacent item, so area B
It may be defined in a color other than the display color of the item. However, by defining the pressed reverse color as a color that is not used by any item on the display screen, the pressed reverse color can be used regardless of which item is pressed.
That is, one press reverse color may be defined for one screen.

The pressed color definition data storage means 18 stores the data of the pressed reverse color defined for each screen. The defined pressed reverse color is the display of the item adjacent to the reversed color of the pressed item. It is not always necessary to define a different color for each screen, as it may be different from the color.

[0019]

As described in detail above, according to the present invention, the storage means for storing the display color of the input item is provided, and when the input item is pressed, the display color corresponding to the pressed input item is displayed. Since the display color before reading and the display color before pressing is changed to the read display color from the storage means, it is possible to prevent the reverse color when the input item is pressed from becoming the same color as the adjacent item, The operator can surely recognize the pressing of the item.
