DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a touch input device suitable for a portable telephone, particularly a telephone such as a wristwatch-type PHS.

[0002]

[Prior art]

(1) Japanese Patent Application Laid-Open No. Hei 8-68871 describes a watch-type telephone which dials with a crown. In the gazette, the crown is rotated and the hand on the display panel is turned to select a number on the display panel, and the selected number is confirmed by pressing the crown, and this is set to all numbers of the telephone number. There has been disclosed a technique of calling a telephone of the other party by doing it.

(2) JP-A-5-209974 describes a tablet-type display device having a transparent tablet switch on a display screen. In this publication, a dial of an analog clock is displayed on the display screen, and the time can be input to the display device by touching the dial corresponding to the time to be input. A technique is disclosed in which time can be easily and accurately input without depending on the character recognition accuracy.

[0004]

With respect to the prior art (1), since the crown is so small in size, it is more difficult than necessary to turn the crown accurately with a finger. Since it is a method of moving the hand on the display panel and selecting the number on the display panel as the number of the telephone number while rotating the crown that takes time and effort for finger operation, for example, on the display panel When selecting a number farther from the currently selected number, or when using a telephone number with a large number of digits to be entered, it takes time and effort and is not a comfortable operation. .

[0005] Therefore, in the present invention, instead of the operation of moving the hands on the display panel by the crown, any display information such as numerals generally arranged on the display panel is selected and the arbitrary display information is selected. Display information that is far from the position of the display information can be easily and quickly selected, so that even if there are many display information to be selected, it can be performed easily and comfortably without time and effort. Is one of the issues to be solved.

With respect to the prior art (2), the pen touch operation on the dial is a relatively time-consuming and cumbersome operation as is well known, but such a troublesome operation is performed by a telephone number having a large number of digits. The operation of the numeral of [1] greatly lacks convenience for the user. In this way, pen touch can accurately select the intended number, while
The operability is inconvenient. Therefore, it is conceivable to select the numbers on the dial with finger touch instead of pen touch, but if the arrangement interval of the numbers on the dial is less than the size of the finger, the intended number is just touched. In addition, there is a high possibility that other numbers are touched, that is, there is a high possibility of erroneous operation. Therefore, the accuracy of selection is inferior to pen touch.

Therefore, in the present invention, while a pen touch operation is possible, a finger touch operation is also possible, and even if a finger touch operation is performed, the possibility of erroneous operation is eliminated or greatly reduced. Another problem to be solved is to ensure accurate operability by operation.

[0008]

According to the present invention, there is provided a display panel on which a plurality of display information can be arranged and displayed in a predetermined arrangement form, and a display panel on which the display information on the display panel can be visually recognized. The above-mentioned problem is solved by a tablet which is arranged and has a plurality of selection areas corresponding to the respective display information, and an erroneous operation prevention means for preventing an erroneous operation on a selection area adjacent to the selection area to be operated. doing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a touch input device according to an embodiment of the present invention will be described in detail with reference to FIGS. The touch input device according to the present embodiment is a wristwatch type mobile phone, particularly a PHS (Personal Handyphone Sy).
Stem) will be described, but the present invention is not limited to this. FIGS. 1 to 3 do not show the overall configuration of the PHS, and only show the main parts of the touch input device according to the present embodiment incorporated in the PHS. FIG. 4 is a circuit block diagram of the PHS.

First, referring to FIG. 1, the touch input device according to the present embodiment includes a display panel 1, a tablet 2, a display 3, and an erroneous operation prevention mechanism 4. The erroneous operation prevention mechanism 4 is not shown in FIG. 1 for clarity of illustration, and is constituted by a convex portion on the tablet 2 as specifically shown in FIG. Therefore, the symbols are referred to as the malfunction prevention mechanism 4 and the protrusions 4.

The display panel 1 is formed in a circular shape. In this circular area, numbers 0 to 9 and symbols # and * are arranged in the same manner as the arrangement of the time display numerals of the analog clock. ing. These numbers and symbols are displayed information (but
The display information is not marked on the display panel 1 for obviousness. ). This number corresponds to the input number of the telephone number, and the symbols # and * are symbols frequently used in PHS operations, and thus the details are omitted. Of course, symbols other than these symbols may be used depending on the function of the PHS. In addition, the number of display of the numeral and the symbol is 12, but it is needless to say that the number may be more or less.

The indicator 3 is provided in the central area of the display panel 1.
Is arranged. The display 3 is arranged in the central area of the display panel 3, but may be arranged at another position. The display information may be graphics, characters, or other display information in addition to the numbers and symbols.

As shown in FIG. 2, the tablet 2 has selection areas 2a, 2b,... Which sense and respond to touch input in correspondence with the numbers and symbols on the display panel 1, respectively. The areas between the selected areas 2a, 2b,... Are non-selected areas 2a ′, 2b ′,. Each of these selection areas 2a, 2b,... Is an area corresponding to the display information of each of the numerals and symbols. In this case, the arrangement form of the display information is matched to the arrangement form of the time display numerals of the analog timepiece in the present embodiment in order to facilitate the understanding of the description, but is not limited to this. , Zigzag, or any other arrangement form, but it is necessary that a non-selection area exists between each selection area.

The tablet 2 is arranged on the display panel 1. The tablet 2 is made of any material, as long as the display information on the display panel 1 is visible, but is preferably made of a translucent material, and most preferably made of a transparent material. The tablet 2 may be colored. The tablet 2 has a rectangular shape larger than the display panel 1, but is not limited to the rectangular shape. Because the size of tablet 2 is larger than that of display panel 1,
It can be used for displaying other display information in the space where the shape is left. The tablet 2 can output coordinate data of the touch position when the tablet 2 is externally touched with a pen or a finger. Since the basic configuration of the tablet 1 and the operation and action of the touch operation are well known, further description is omitted.

The display 3 displays display information on the display panel 1 corresponding to the coordinate position touch-input via the tablet 2. The display 3 displays the selected latest display information with the cursor 5 to make the touch operation more convenient. Display 3
Is not separately provided from the display panel 1, but is obtained by dividing and using a selected area in the liquid crystal display device, and is referred to as a display here for convenience. Of course, the display 3 is connected to the display panel 1
Alternatively, it may be configured separately.

The erroneous operation prevention mechanism 4 prevents erroneous operation on a selection area adjacent to the selection area to be operated on the tablet 2 and, as shown in FIG. And a non-selection area (area insensitive to a touch operation) 2a ', which is a position between the selection area 2b and the adjacent selection area 2b. 2b 'is a non-selection area between the selection area 2b and the selection area adjacent thereto. Therefore, in the case of touching the pen, the selection area 2a or the selection area 2b is accurately operated, and the selection area 2a and the selection area 2b are not operated at the same time. Even if the touch input is performed on the selection area 2a, the selection area 2a is
b may be touch-input. in this case,
Since the erroneous operation prevention mechanism in the present embodiment is configured by the convex portion 4, when the selection area 1a is a correct touch input, the belly 6b of the finger 6 is pressed by the convex portion 4, so that the belly 6b is selected. Touch input of the area 2b is prevented. Therefore, in the case of the present embodiment, an erroneous operation can be reliably and easily prevented even with a touch input by a finger.

Although the malfunction prevention mechanism of the present embodiment is constituted by the projections 4 on the tablet 2, the invention is not limited to this. For example, the periphery of the tablet 2, for example, a sheet having irregularities thereon (Not shown) may be arranged, and a sheet (not shown) having a relatively large thickness which is substantially equal to the height of the convex portion 4 is arranged, and the sheet corresponds to the selected area. The opening may be provided only at the portion where the projection is formed, and the unopened sheet portion may be capable of exhibiting the same function as that of the convex portion. Any of such structures can constitute an effective malfunction prevention mechanism. In addition,
As a specific preventive action, for example, when the user of the PHS selects a digit of a telephone number for a dial operation with a finger, the convex portion guides the user accurately and easily to the target dialed digit display information. The finger is in contact with the correct selection area, but the finger pad is convex and does not touch the adjacent selection area. In addition, when the recognition of the selection of a number is performed when the finger is separated from the tablet, the user checks the feel of the convex portion with the finger while confirming the target selected area accurately. , And release the finger after recognizing that the finger has reached the next target selection area, so that erroneous input can be reliably prevented.

As described above, according to the present embodiment, there is no operation of moving the hands on the display panel surface by the crown for dial operation, and the display information such as numbers arranged on the display panel is not included. It is possible to easily and quickly select any display information even if the display information is located far from the position of the arbitrary display information, and it takes time and effort even if the number of display information to be selected increases. It can be done easily and comfortably without the need. In addition, pen touch operation is possible and finger touch operation is also possible at the same time. In addition, when finger touch operation is performed, the possibility of erroneous operation is prevented by the malfunction prevention mechanism, so even finger touch is as accurate as pen touch operation Operability can be secured.
