Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus, a cash dispenser, an electronic organizer, a calculator, and the like, which displays a graphic such as a button indicating a pressed position on a display surface and uses a touch panel attached to the display surface. The present invention relates to an input device with an erroneous input detection function and a erroneous input detection method for an input device, which are preferably applied to a device that receives an input from an operator.

[0002]

2. Description of the Related Art Conventionally, a display surface and a touch panel are provided,
An input device has been developed that allows a predetermined input to be performed by an operator's finger touching a touch panel while looking at a display surface.

In such an input device, a button (for example, a button), a character, and a graphic such as a picture (hereinafter, also simply referred to as a graphic) are displayed on a display surface. Is displayed to urge the operator to press the touch panel.

[0004] Here, an effective input area is defined in an area of the touch panel corresponding to an operation button displayed on the display surface, and when the operator presses the input effective area on the touch panel, the pressed position is determined. Is detected, and it is determined that the button corresponding to the position is pressed.

On the other hand, in such an input device, the operator often presses an area other than the normal input area, resulting in an erroneous input (input error).

That is, in the case of a touch panel, since a long stroke like a keyboard cannot be obtained, the operator cannot obtain a sense of whether or not the touch has been sufficiently pressed. There are cases.

In such a case, the contact area between the operator's finger and the display surface is unstable because it changes depending on the pressing force of the operator, and a position deviating from the intended button is pressed. Therefore, the operator presses an area other than the normal input area.

For this reason, in the prior art, when the operator presses an area other than the normal input area, for example, a sound indicating a warning is generated to notify the operator of the input error.

However, in this configuration, the operator can recognize that an input error has been made, but cannot know which position on the touch panel has been pressed and the input error has been made. There is a danger of

In order to solve such a problem, in a conventional input device, for example, as in an "input device" disclosed in Japanese Patent Application Laid-Open No. 5-88814, which position is pressed when an input error is detected. There has been proposed a device provided with a control means for displaying whether the operation has been performed.

The "input device" disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 5-88814 will be described below with reference to FIG. FIGS. 5A and 5B are plan views of a display surface of an information retrieval device using a conventional input device.

In FIG. 5, reference numeral 100 denotes a display device of the information search device; 200, a display surface of the display device 100;
0 is a touch panel provided along the display surface 200, 4
00 is an operator's finger.

On the display surface 200, a screen for searching for data is displayed. On the left side of the display surface 200, five lines of data classification names 500 are displayed, and a button figure 600 corresponding thereto is displayed on the display surface 200. Are displayed vertically on the right side of.

As shown in FIG. 5A, a button graphic 700 corresponding to the end is displayed at the lower center of the screen. The operator presses one of the button figures 600 and 700 with the finger 400. Touch panel 300 detects a touch due to this pressing, and an input is performed.

Then, as shown in FIG. 5B,
When the operator erroneously presses the area other than the button graphics 600 and 700 with the finger 400, the touch panel 300 detects the position pressed with the finger 400, and the information search device determines that there is an input error and generates a warning sound. The finger 4
When the operator releases 00 from the touch panel 300, the marker figure 800 is displayed on the display surface 200 at the position where the operator erroneously pressed the marker figure 800 for a predetermined time.

Therefore, according to the above-mentioned prior art, the operator can immediately determine that an erroneous input has been made by a warning sound, and the input position where the operator has made an erroneous input is indicated by the marker figure 80.
0 can be recognized.

[0017]

However, in the above-mentioned prior art, although it is possible to confirm the pressed position which the operator has erroneously input, it is difficult to determine where the correct input area to be pressed next by the operator is. There is a problem that it is difficult to recognize.

That is, as described above, a button figure for performing an operation is displayed on the display surface, but the input effective area on the touch panel may be set smaller than the button figure.

For example, when the interval between adjacent button figures becomes narrow and there is a possibility that the next button figure may be erroneously pressed, as in the case of arranging button figures on the entire screen of the display surface on which an operation is to be performed, It is necessary to set the input effective area on the touch panel smaller than this button figure.

As described above, when the input effective area on the touch panel is set smaller than the button figure, if the operator makes an input error with the input device having the conventional configuration,
The pressed position is "inside the display area of the button and out of the valid input area", which causes confusion.

Here, a description will be given of a display when an operator makes an input error with a conventional input device when the input effective area on the touch panel is set smaller than the button figure with reference to FIG. . FIG. 6 shows a display screen when an operator makes an input error in the conventional input device.

As shown in FIG. 6, when the operator makes an input error with the input device having the conventional configuration and the pressed position is "in the display area of the button and out of the valid input area", A marker 210 is displayed inside the button graphic.

Therefore, the conventional technique has a problem that, in the case as shown in FIG. 6, it cannot be transmitted to the operator which position should be pressed to avoid an input error.

The present invention has been made in view of the above circumstances, and provides an erroneous input detection function excellent in operability capable of presenting a correct input effective area to an operator who has pressed an erroneous position and preventing an incorrect input again. It is an object of the present invention to provide an input device with a tag and a method for detecting an erroneous input of the input device.
