Description
Technical field
The utility model relates to touch control panel device.
Background technology
For the structure of the touch control panel device for detection of input position, carried out various research in the past, as an example, known have a capacitive touch control panel device.For example, patent documentation 1 and the disclosed touch control panel device of patent documentation 2, have contact panel, this contact panel forms by dielectric layer being set between a pair of substrate, and described a pair of substrate possesses respectively multiple electric conductors of the pattern form with regulation.In addition, as shown in the contact panel exploded perspective view of Figure 10, in contact panel, being formed in each end of the multiple electric conductors on each substrate, the lead-out wiring (draw I go out join Line) that one end connects is formed on the circumference of substrate, and the other end 101,102 of these lead-out wirings is to concentrate the mode of bunchy to be configured in respectively the regulation position of the side edge part 103,104 of each substrate.As shown in the contact panel major part amplification plan view of Figure 11, in the vertical view of contact panel, the other end 101,102 of each lead-out wiring forms in the mode of the lateral margin 105 perpendicular to contact panel, and the lateral margin 105 of this contact panel is to concentrate the mode of bunchy to dispose the lateral margin of the contact panel of the other end 101,102 of each lead-out wiring.This touch control panel device, by the terminal of flexible distributing board is electrically connected with each other end 101,102 of the lead-out wiring configuring in the mode of concentrating bunchy, can be directed to touching signals outside position of touch judgement circuit, detects position of touch.
In this touch control panel device, in order to strengthen the ratio of setting touch region with respect to the whole region of contact panel, it is desirable to make the circumference region of the contact panel that disposes lead-in wire narrow as far as possible (narrow frame).In order to realize described expectation, need to reduce the join domain (overlapping region) of the terminal of flexible distributing board and the other end of each lead-out wiring, also produced necessity of the terminal miniaturization of the flexible distributing board that need to make the side edge part that is configured in contact panel thereupon.In addition, it is desirable to, also make the main part (part of drawing to the side of contact panel of flexible distributing board; Flexible wired main body) (ス リ system) attenuates.
Therefore, in the past, the intubating length inserting to contact panel by the terminal that reduces as far as possible to connect on one end of flexible wired main body is realized the narrow frame of contact panel, also make the width of flexible wired main body become narrow width simultaneously, therefore the terminal 112 that as shown in figure 12, width is formed as connect on one end of flexible wired main body 111 of narrow width forms in the mode that becomes the shape of stretching out to the side of this main body 111.The front-end edge of terminal 112, forms in the mode of lateral margin of side edge part of the contact panel that is parallel to mounting terminal 112.In addition, in the time as shown in figure 13 flexible distributing board 110 being set on contact panel 100, near the part terminal of flexible distributing board 110, form in the teat 113(figure of the outstanding general triangular shaped in the outside of contact panel 100 by the single-point part of irising out of rule), the wire 115 guiding to the extension 112a of terminal 112 is configured in described teat 113.

Patent documentation 1: No. 2003-173238, Japanese Patent Publication communique JP (Fig. 1, Fig. 5)
Patent documentation 2: No. WO2011/111748, International Publication communique
Described touch control panel device uses in the lip-deep mode that contact panel is arranged on to liquid crystal indicator or CRT etc., and now, flexible distributing board is bent and judges and be connected with circuit with position of touch.Follow the bending of flexible distributing board, have at the terminal of flexible distributing board and the connecting portion of contact panel and can produce the power that terminal is peeled off, thereby cause being fixed on the problem that the terminal of the flexible distributing board on lead-out wiring is easily peeled off.Now, be difficult to maintain the stable conducting state of flexible distributing board and lead-out wiring, the detection of position of touch becomes difficulty.
In addition, because near the part terminal of flexible distributing board is formed with the teat of the general triangular shaped outstanding to the outside of contact panel, so shortage compactedness, in addition, also there is following problems: in the time touch control panel device being installed to liquid crystal indicator or CRT etc. surperficial, described teat becomes obstacle, becomes the restriction in product design, and the operability of fitting operation is reduced.
