Herein, the film substrate 2 of the structure of the foregoing description is with film substrate 15 differences of present embodiment: form to such an extent that grow on this aspect than slit 3a, 3a at a pair of slit 16a, the 16a of the strip that is provided with on first insulated substrate 16, also be in addition: the middle body at the electric conductor 10 of the second insulated substrate 17 is not provided with on resist layer 13 these aspects, also be in addition: be provided with on fixed contact 11 these aspects that a plurality of (being two in the present embodiment) be formed in the push switch that switch substrate 18 forms, thereby formed different structures respectively.
Promptly, in the present embodiment, when pushing the 7b of touch portion of touch pad 7, make the size of the pressing body 14a of the holding components 14 of configuration below first insulated substrate 16 form strip, make it be positioned on the position that the effective input area with the resistive element 9 that is provided with at first insulated substrate 16 and the second insulated substrate 17 and electric conductor 10 coincides, described first insulated substrate 16 and the second insulated substrate 17 are configured in the below with respect to this touch pad 7, the size of the length direction of this strip forms, with the roughly the same length dimension of size of the length direction of the strip of the 7b of touch portion of described touch pad 7.In other words, the size of the length direction of the pressing body 14a of holding components 14 is set at more than the length dimension of effective input area, makes to cover this effective input area.
And, by downside at the described pressing body 14a that is configured to this strip, the push switch of a plurality of (being two in the present embodiment) is set, even when the optional position of the 7b of touch portion that pushes touch pad 7, this pressing force makes any one action of a plurality of push switch that is configured in the below by pressing body 14a.And, at this moment, as shown in Figure 8, the fixed contact 11 that forms in switch substrate 18 connect in parallel mutually each center contact 11a each other with each perimeter contact 11b each other, as long as any one unlatching just can detect output.
Promptly, as the action of present embodiment,, push at any part by making its move left and right with the 7b of this touch portion of touches such as finger, make thus corresponding to the electric conductor 10 of pushing the position to contact, based on the conductive pattern 10a that derives from the electric conductor 10 of this pressing position with resistive element 9; And the resistance value between the conductive pattern 9c, the 9d that derive from electrode part 9a, the 9b of the both sides of resistive element 9 detects the magnitude of voltage that is output, and similarly carries out setting or selection with the corresponding output valve of pressing position.
Afterwards, under the situation of determining this setting and chosen content, needn't left or move right makes the finger on the touch pad 7 move to central authorities, continues further to push the 7b of touch portion of touch pad 7 downwards.
That is, if push the 7b of touch portion of touch pad 7, then by below the configuration first and second insulated substrate 16,17, the pressing body 14a that is configured holding components 14 thereunder is pressed.
