- FIG. 9B is an input device in the opened state.
- the input device 10 of this modification has a first display element 52 attached to the first detection region 31 a of the film sensor 30 via an adhesive layer 47.
- the second display element 53 is bonded to the second detection region 31 b of the film sensor 30 via the adhesive layer 48. That is, the first display element 52 is provided at a position facing the first front panel 21, and the second display element 53 is provided at a position facing the second front panel 22.
- the first display element 52 or the second display element 53 is not overlapped on the back surface side, so that the opening shown in FIG. In this state, the film sensor 30 is easily bent. Therefore, when the third electrode 36 (not shown in FIG. 9) is formed with the same area as the first electrode 34 and the second electrode 35, the third electrode 36 is interposed between the detected object and the third electrode 36. Since the capacitance formed is reduced, the detection sensitivity in the third detection region 31c is likely to be lowered. Therefore, as shown in FIGS. 4 and 6 to 8, in the third detection region 31c, the area of the third electrode 36 is made larger than the areas of the first electrode 34 and the second electrode 35. The detection sensitivity variation can be effectively suppressed, and variations in detection sensitivity can be reduced.
- FIG. 10 shows an input device of a fifth modification of the present embodiment, and shows a sectional view when folded.
- the input device 10 of the present modification is different in that the first surface panel 21 and the second surface panel 22 face the outside in a folded state.
- a film sensor 30 is bonded to the back side of the first front panel 21 and the back side of the second front panel 22.
- the third detection region 31c of the film sensor 30 is curved so as to protrude toward the input surfaces 10a to 10c.
- the area of the third electrode 36 in the third detection region 31c is made smaller than that of the first electrode 34 or the second electrode 35, so that By reducing the value of the capacitance formed between the detection body and the first detection region 31a, the second detection region 31b, and the third detection region 31c, variations in detection sensitivity can be suppressed.

Abstract
Description
図6は、本実施形態の第1の変形例の入力装置10を示し、フィルムセンサ30の部分拡大平面図を示す。図1~図3に示すように、連結部26の折り畳み開閉軸に平行な方向を第1の方向(Y1-Y2方向)として、第1の方向に交差する方向を第2の方向(X1-X2方向)とする。図6に示すように、フィルムセンサ30を開いた状態の平面視において、第3の検出領域31cには、第2の方向(X1-X2方向)において複数の第3の電極36が配列されており、第2の方向(X1-X2方向)における第3の検出領域31cの中央部に配置された第3の電極36bの面積が、第2の方向における第3の検出領域31cの縁部に配置された第3の電極36a、36cの面積よりも大きい。 (First modification)
FIG. 6 shows the
図7は、本実施形態の第2の変形例の入力装置を示し、フィルムセンサの部分拡大平面図を示す。本変形例において、第1の電極34、第2の電極35及び第3の電極36は、それぞれ個別に引出配線42に接続されている。引出配線42は、各検出領域31a、31b、31cの外側の非検出領域32を引き回されて、外部のIC等の制御部に接続される。よって、第1の電極34、第2の電極35及び第3の電極36は、それぞれ独立して、外部の制御部に並列に接続される。すなわち、複数の第3の電極36は、第1の電極34、第2の電極35と同一の制御部に接続されて信号処理されため、第3の検出領域31cの入力操作に対して、個別に制御部を設けて信号処理を行う必要がない。また、各電極34、35、36は、互いに電気的に干渉することが抑制されるので、入力操作が行われた位置の検出精度を向上させることが可能である。 (Second modification)
FIG. 7 shows an input device of a second modification of the present embodiment, and shows a partially enlarged plan view of the film sensor. In this modification, the
図8は、本実施形態の第3の変形例の入力装置を示し、フィルムセンサの部分拡大平面図を示す。図4、図5、図7に示すフィルムセンサ30は、第1の電極34及び第2の電極35のそれぞれの面積に対して、複数の第3の電極36のそれぞれの面積を大きく形成しているが、これに限定されない。図8に示すように、第3の電極36の個数を多く形成して、すなわち、第3の検出領域31cの面積に対する第3の電極36の合計面積の比率が、第1の検出領域31aの面積に対する第1の電極34の合計面積の比率、または第2の検出領域31bの面積に対する第2の電極35の合計面積の比率よりも大きくなるように、形成されている。このような構成であっても、第3の検出領域31cにおける検出感度を向上させて、入力装置10の検出感度のばらつきを抑制することができる。 (Third Modification)

図10は、本実施形態の第5の変形例の入力装置を示し、折り畳み時の断面図を示す。本変形例の入力装置10においては、折り畳んだ状態で第1の表面パネル21、第2の表面パネル22が外側に面する点で異なっている。そして、第1の表面パネル21の裏面側及び第2の表面パネル22の裏面側にはフィルムセンサ30が貼り合わされている。本変形例の入力装置10を開いた状態としたとき、フィルムセンサ30の第3の検出領域31cは、入力面10a~10c側に向かって凸に湾曲する。 (Fifth modification)
