従来、携帯型ゲーム機、携帯電話、携帯情報端末(PDA)など、ユーザーが携帯して使用できる携帯情報機器が広く知られている。このような携帯情報機器としては図14、図15に示すようなものがある。   2. Description of the Related Art Conventionally, portable information devices that can be carried and used by users, such as portable game machines, cellular phones, and personal digital assistants (PDAs), are widely known. Examples of such portable information devices include those shown in FIGS.

図14は前記従来の携帯情報機器の一つである携帯電話の外観構成を示す斜視図である(特許文献1参照)。図14において、携帯電話1の前面には文字や数字、記号などが表示される液晶ディスプレイ等の表示部2が設けられている。この表示部2の下部近傍には、表示画面の左右方向のスクロール動作をユーザーの指5で行なうための第1のスクロール操作部3が設けられている。また、この表示部2の左側部近傍には、表示画面の上下方向のスクロール動作をユーザーの指5で行なうための第2のスクロール操作部4が設けられている。ユーザーはこれら第1、第2のスクロール操作部を用いて表示画面を上下方向と左右方向など、二次元方向に操作できるものである。   FIG. 14 is a perspective view showing an external configuration of a mobile phone which is one of the conventional mobile information devices (see Patent Document 1). In FIG. 14, a display unit 2 such as a liquid crystal display on which characters, numbers, symbols, and the like are displayed is provided on the front surface of the mobile phone 1. Near the lower portion of the display unit 2, a first scroll operation unit 3 for performing a horizontal scrolling operation of the display screen with the user's finger 5 is provided. Near the left side of the display unit 2, a second scroll operation unit 4 for performing a vertical scrolling operation of the display screen with the user's finger 5 is provided. The user can operate the display screen in two-dimensional directions such as up and down and left and right using these first and second scroll operation units.

また、図15は従来の他の携帯電話の構成を示す平面図である(特許文献2参照)。図15において、携帯電話11は、矩形からなる薄型筐体の前面に表示画面12が設けられ、4つの側面にはタッチパッド13〜16がそれぞれ形成されている。タッチパッド13〜16は、その長手方向が、表示画面12に平行となるように配置された細長い形状の操作検出手段であり、1又は2以上のタッチパッド13〜16に対し、表示画面12に平行なスライド操作を行うことによって、表示画面12をスクロールしたり、表示画像の回転、表示倍率の変更を行なったりできるものである。   FIG. 15 is a plan view showing the configuration of another conventional mobile phone (see Patent Document 2).

しかしながら、上記従来の携帯電話1においては、第1、第2のスクロール操作部3、4を表示部2の近傍に設けるスペースが必要であるため、携帯電話1の前面に一定の大きさの表示部2を配置しようとすると、携帯電話1の大きさが大きくなってしまう。また、携帯電話1の大きさを変えずに、表示部2をできるだけ大きくしようとすると、第1、第2のスクロール操作部3、4の大きさを小さくせざるを得なくなるため、第1、第2のスクロール操作部3、4の操作性が悪化するという問題点があった。   However, since the conventional mobile phone 1 requires a space in which the first and second scroll operation units 3 and 4 are provided in the vicinity of the display unit 2, a fixed-size display is provided on the front surface of the mobile phone 1. If it is going to arrange | position the part 2, the magnitude | size of the mobile telephone 1 will become large. If the display unit 2 is made as large as possible without changing the size of the mobile phone 1, the first and second scroll operation units 3 and 4 must be reduced in size. There was a problem that the operability of the second scroll operation units 3 and 4 deteriorated.

また、上記従来の他の携帯電話11においては、タッチパッド13〜16は携帯電話11の4つの側面に形成されているため、これらのタッチパッド13〜16によって表示画面12の大きさが制限を受けることがない。しかしながら、これらのタッチパッド13〜16に対し、表示画面12に平行なスライド操作を行うには片手ではきわめて困難であり、両手を使わねばならないという問題点があった。   Further, in the other conventional mobile phone 11, the touch pads 13 to 16 are formed on the four side surfaces of the mobile phone 11, so that the size of the display screen 12 is limited by these touch pads 13 to 16. I do not receive it. However, it is extremely difficult with one hand to perform a slide operation parallel to the display screen 12 on the touch pads 13 to 16, and there is a problem that both hands must be used.

本発明は上記従来の課題を解決するもので、携帯情報機器の筐体にタッチパッド等の入力手段を付加することなく、表示画面のスクロール、拡大、縮小、音量の調整等の多様な制御を片手での簡単な操作で行なうことができる携帯情報機器を提供するものである。   The present invention solves the above-described conventional problems, and performs various controls such as scrolling, enlarging, reducing, and adjusting the volume of the display screen without adding an input means such as a touch pad to the casing of the portable information device.

And a detection element 44 and a drive element 45 disposed at the center and the end on the surface of the second beam-like vibration body 43, respectively. The detection element 44 and the drive element 45 are formed by sequentially laminating a lower electrode, a piezoelectric layer made of PZT or the like, and an upper electrode (not shown). The detection element 44 and the drive element 45 are electrically connected to the printed board 24 by a wiring pattern (not shown).

ここで、前記半導体基板31の底面は、前記筐体22の背面22dに発生する歪が前記第1および第2の振動子32、42に伝達されるようにAu−Au接合等の金属系接合材やエポキシ樹脂等の剛性を有する物質50で接続固定されている。さらに、前記第2の振動子42の第2の梁状の振動体43の長手方向は、前記第1の振動子32の第1の梁状の振動体33の長手方向とは互いに直交するように配置している。   Here, the bottom surface of the semiconductor substrate 31 is a metal-based joint such as an Au—Au joint so that the strain generated on the back surface 22 d of the housing 22 is transmitted to the first and second vibrators 32, 42. It is connected and fixed by a material 50 having rigidity such as a material or an epoxy resin. Further, the longitudinal direction of the second beam-like vibrator 43 of the second vibrator 42 is orthogonal to the longitudinal direction of the first beam-like vibrator 33 of the first vibrator 32. Is arranged.

上記歪検出素子26において、前記プリント基板24から第1の振動子32の駆動素子35に第1の梁状の振動体33の固有振動数faに近接した周波数を持つ交流電圧が印加されると、前記駆動素子35は第1の梁状の振動体33の長手方向に伸縮振動を開始する。この伸縮振動によって第1の梁状の振動体33は自身が持つ固有振動数faで上下に弦振動を開始する。この弦振動は検出素子34によって受信され、この検出素子34から第1の梁状の振動体33の固有振動数faと等しい周波数を持つ交流信号が発生する。この交流信号は前記プリント基板24内で位相調整、増幅されて駆動素子35にフィードバックされる。これにより、第1の梁状の振動体33はその固有振動数faに等しい周波数で上下に弦振動を持続する。同様にして、前記プリント基板24の信号処理により、第2の梁状の振動体43はその固有振動数fbに等しい周波数で上下に弦振動を持続することになる。 In the strain detection element 26, an AC voltage having a frequency close to the natural frequency f a of the printed first beam-like vibrator 33 in the drive element 35 from the substrate 24 first oscillator 32 is applied Then, the drive element 35 starts stretching vibration in the longitudinal direction of the first beam-like vibrating body 33. Due to this stretching vibration, the first beam-like vibrating body 33 starts string vibration up and down at its own natural frequency f a . This string vibration is received by the detection element 34, and an AC signal having a frequency equal to the natural frequency f a of the first beam-like vibrating body 33 is generated from the detection element 34. This AC signal is phase-adjusted and amplified in the printed circuit board 24 and fed back to the drive element 35. Accordingly, the first beam-like vibrator 33 to sustain the string vibrates vertically at a frequency equal to the natural frequency f a. Similarly, the signal processing of the printed circuit board 24, the second beam-like vibrator 43 will be to sustain the string vibrates vertically at a frequency equal to the natural frequency f b.

このように第1の振動子32における第1の梁状の振動体33と、第2の振動子42における第2の梁状の振動体43とが弦振動をしている状態で、前記筐体22の背面22dに前記第1の梁状の振動体33の長手方向に平行な荷重Fが印加されると、前記歪検出素子26は前記第1の梁状の振動体33の長手方向に伸びるとともに、前記筐体22の背面22dのポアソン比に相当する長さだけ前記第2の梁状の振動体43の長手方向に縮む。これにより、前記第1の梁状の振動体33には伸張力が働くため、第1の梁状の振動体33の振動周波数はfaからfa+fa′に上昇するとともに、第2の梁状の振動体43の振動周波数はfbからfb−fb′に低下することになる。したがって、前記第1の梁状の振動体33の振動周波数と、第2の梁状の振動体43の振動周波数との差をとることにより、前記筐体22の背面22dに働く荷重を高感度で測定することができる。また、前記第1の振動子32、第2の振動子42とは同一素材の半導体基板から形成しているため、温度変化に対する振動周波数の変化の方向と変化量は同一となる。これにより、温度変化による振動周波数の変動をキャンセルできるため、前記筐体22の背面22dに働く荷重を正確に測定できるものである。 In this manner, the first beam-like vibrating body 33 in the first vibrator 32 and the second beam-like vibrating body 43 in the second vibrator 42 are in string vibration, and the housing When a load F parallel to the longitudinal direction of the first beam-like vibrating body 33 is applied to the back surface 22 d of the body 22, the strain detection element 26 moves in the longitudinal direction of the first beam-like vibrating body 33. While extending, it contracts in the longitudinal direction of the second beam-like vibrating body 43 by a length corresponding to the Poisson's ratio of the back surface 22d of the housing 22. Accordingly, the order in the first beam-like vibrator 33 acting stretching force, together with the oscillation frequency of the first beam-like vibrator 33 rises to f a + f a 'from f a, the second vibration frequency of the beam-shaped vibrating body 43 will be reduced to f b -f b 'from f b. Therefore, by taking the difference between the vibration frequency of the first beam-like vibrating body 33 and the vibration frequency of the second beam-like vibrating body 43, the load acting on the back surface 22d of the housing 22 is highly sensitive. Can be measured. Further, since the first vibrator 32 and the second vibrator 42 are formed from a semiconductor substrate made of the same material, the direction and amount of change of the vibration frequency with respect to the temperature change are the same. As a result, fluctuations in the vibration frequency due to temperature changes can be canceled, so that the load acting on the back surface 22d of the housing 22 can be accurately measured.

再び、図1(b)において、本発明の実施の形態1における携帯情報機器21の筐体22をたとえば、片手の親指と中指で持ちながら、人差し指で背面22dに圧縮荷重F1を加えると、前記筐体22の背面22dは紙面の上方に撓む。これにより、前記歪検出素子26は前記第1の梁状の振動体33の長手方向に伸びるとともに、前記筐体22の背面22dのポアソン比に相当する長さだけ前記第2の梁状の振動体43の長手方向に縮む。そのため、前記歪検出素子26における前記第1の梁状の振動体33の振動周波数と、第2の梁状の振動体43の振動周波数との差Δはfa−fbから(fa−fb)+(fa′+fb′)に、(fa′+fb′)だけ増加する。一方、本発明の実施の形態における携帯情報機器21の筐体22をたとえば、片手の親指と中指で持ちながら、第1の側面22bと第2の側面22cとに圧縮荷重F2を加えると、前記歪検出素子26は前記第1の梁状の振動体33の長手方向に縮むとともに、前記筐体22の背面22dのポアソン比に相当する長さだけ前記第2の梁状の振動体43の長手方向に伸びる。そのため、前記歪検出素子26における前記第1の梁状の振動体33の振動周波数と、第2の梁状の振動体43の振動周波数との差Δはfa−fbから(fa−fb)−(fa′+fb′)に、(fa′+fb′)だけ減少する。このように、前記歪検出素子26における前記第1の梁状の振動体33と、第2の梁状の振動体43とから発生する電気信号をプリント基板24に搭載した電子回路で処理することにより、前記筐体22に加える圧縮荷重により変化する、これら2つの交流信号の周波数の差Δの増減分に相当する電気信号、たとえば電圧信号を得ることができる。 Again, in FIG. 1 (b), the housing 22 of the portable information apparatus 21 according to the first embodiment of the present invention For example, while holding in one hand the thumb and middle finger, when the back 22d with an index finger applying a compressive load F 1, The rear surface 22d of the housing 22 bends above the paper surface. As a result, the strain detection element 26 extends in the longitudinal direction of the first beam-like vibrating body 33, and the second beam-like vibration has a length corresponding to the Poisson's ratio of the back surface 22d of the housing 22. Shrink in the longitudinal direction of the body 43. Therefore, the difference Δ between the vibration frequency of the first beam-like vibrating body 33 and the vibration frequency of the second beam-like vibrating body 43 in the strain detection element 26 is changed from f a −f b to (f a − f b ) + (f a ′ + f b ′) is increased by (f a ′ + f b ′). On the other hand, when the compressive load F 2 is applied to the first side surface 22b and the second side surface 22c while holding the housing 22 of the portable information device 21 in the embodiment of the present invention with the thumb and middle finger of one hand, The strain detecting element 26 is contracted in the longitudinal direction of the first beam-like vibrating body 33, and the second beam-like vibrating body 43 has a length corresponding to the Poisson's ratio of the back surface 22d of the housing 22. Extends in the longitudinal direction. Therefore, the difference Δ between the vibration frequency of the first beam-like vibrating body 33 and the vibration frequency of the second beam-like vibrating body 43 in the strain detection element 26 is changed from f a −f b to (f a − f b ) − (f a ′ + f b ′) is decreased by (f a ′ + f b ′). In this way, electrical signals generated from the first beam-like vibrating body 33 and the second beam-like vibrating body 43 in the strain detecting element 26 are processed by an electronic circuit mounted on the printed circuit board 24. Thus, it is possible to obtain an electrical signal, for example, a voltage signal, which corresponds to an increase / decrease in the frequency difference Δ between these two AC signals, which changes due to the compressive load applied to the housing 22.

図3は上記の電圧信号の一例を示すもので、図3(a)は本発明の実施の形態1における携帯情報機器21の筐体22に圧縮荷重を加えない、あるいは所定の閾値以下の圧縮荷重しか加えない時に、前記歪検出素子26から発生する電気信号を処理して得られる出力電圧信号を示すもので、出力電圧は発生しない。   FIG. 3 shows an example of the voltage signal described above.

The voltage value of this positive voltage is substantially proportional to the magnitude of the compressive load F 1 applied to the back surface 22 d of the housing 22 of the portable information device 21. Further, FIG. 3C shows the time 0 to t 1 and the time t 2 to t 3 compressed on the first side 22b and the second side 22c of the casing 22 of the portable information device 21 in the embodiment of the present invention. An output voltage signal obtained by processing an electric signal generated from the strain detection element 26 when the load F 2 is applied, and a negative voltage is generated at times 0 to t 1 and t 2 to t 3 . No output voltage is generated after the times t 1 to t 2 and t 3 . The voltage value of the negative voltage is substantially proportional to the magnitude of the compressive load F 2 applied to the back surface 22 d of the housing 22 of the portable information device 21.

(Embodiment 3)
The invention described in claim 2 of the present invention will be described below with reference to the drawings, using Embodiments 3 and 4. 5A is a plan view of portable information device 71 according to Embodiment 3 of the present invention, and FIG. 5B is a cross-sectional view of portable information device 71 taken along the line DD. In the portable information device 71 according to the third embodiment of the present invention, components having the same configurations as those of the portable information device 21 according to the first embodiment of the present invention described above are denoted by the same reference numerals. The description thereof is omitted. 5 (a) and 5 (b), the portable information device 71 in the third embodiment of the present invention is different from the portable information device 21 in the first embodiment of the present invention described above in that two strain detection elements 26a, 26b is disposed in the housing 22 of the portable information device 71 so as to be mechanically coupled to the first side surface 22b. The strain detection elements 26a and 26b are vibrator type strain detection elements formed by finely processing a semiconductor substrate made of silicon or the like, and have the same configuration as that shown in FIG. And a second beam-like vibrator orthogonal to the first beam-like vibrator. Here, the first beam-like vibrator of the strain detection element 26a and the first beam-like vibrator of the strain detection element 26b are arranged on one straight line parallel to the back surface 22d of the housing 22. It is desirable that

図5(a)において、本発明の実施の形態3における携帯情報機器71の筐体22をたとえば、片手の親指と中指、薬指、小指で持ちながら、親指で前記第1の側面22b上で前記歪検出素子26aの背面中央に当る部分に圧縮荷重F3を加えると、前記第1の側面22bは筐体22の中側に撓んで、前記歪検出素子26の第1の梁状の振動体は長手方向に伸びるとともに、この第1の梁状の振動体に対して垂直方向に設けられた第2の梁状の振動体は長手方向に縮む。そのため、第1の梁状の振動体の振動周波数はfaからfa+fa′に上昇するとともに、第2の梁状の振動体の振動周波数はfbからfb−fb′に低下することになる。そのため、前記歪検出素子26aにおける前記第1の梁状の振動体の振動周波数と、第2の梁状の振動体の振動周波数との差Δはfa−fbから(fa−fb)+(fa′+fb′)に、(fa′+fb′)だけ増加する。一方、前記歪検出素子26bは圧縮荷重F3の作用点から離れているために第1、第2の梁状の振動体の振動周波数はほとんど変化しない。そのため、第1の梁状の振動体の振動周波数と、第2の梁状の振動体の振動周波数との差Δ′の変化量はほぼ零に等しくなる。 5A, while holding the housing 22 of the portable information device 71 according to Embodiment 3 of the present invention with, for example, the thumb and middle finger, ring finger, and little finger of one hand, the thumb on the first side surface 22b. When a compressive load F 3 is applied to a portion of the strain detection element 26 a that is in the center of the back surface, the first side surface 22 b bends to the inside of the housing 22, and the first beam-like vibrating body of the strain detection element 26. Extends in the longitudinal direction, and the second beam-like vibrating body provided in a direction perpendicular to the first beam-like vibrating body contracts in the longitudinal direction. Therefore, 'as well as increase the vibration frequency of the second beam-like vibrator f b -f b from f b' oscillation frequency of the first beam-like vibrator f a + f a from f a decrease in Will do. Therefore, the difference Δ between the vibration frequency of the first beam-like vibrating body and the vibration frequency of the second beam-like vibrating body in the strain detection element 26a is changed from f a −f b to (f a −f b ) + (F a ′ + f b ′) is increased by (f a ′ + f b ′). Meanwhile, the strain detection element 26b is first in order away from the point of compression load F 3, the vibration frequency of the second beam-like vibrator is hardly changed. Therefore, the amount of change in the difference Δ ′ between the vibration frequency of the first beam-like vibrating body and the vibration frequency of the second beam-like vibrating body is substantially equal to zero.

次に、前記第1の側面22b上で同一の圧縮荷重F3を加える位置を前記歪検出素子26bの方向に移動させると、前記歪検出素子26aの第1の梁状の振動体の長手方向の伸び量が減少するとともに、第2の梁状の振動体の長手方向の縮み形量が減少する。そのため、前記歪検出素子26aの第1の梁状の振動体の振動周波数と、第2の梁状の振動体の振動周波数との差Δの変化量は前の場合より小さくなる。一方、前記歪検出素子26bと圧縮荷重F3の作用点との距離が縮まるために、前記歪検出素子26bの第1の梁状の振動体の長手方向の伸び量が増加するとともに、第2の梁状の振動体の長手方向の縮み形量も増加する。そのため、前記歪検出素子26bの第1の梁状の振動体の振動周波数と、第2の梁状の振動体の振動周波数との差Δ′の変化量が増加する。 Next, when the position where the same compressive load F 3 is applied on the first side surface 22b is moved in the direction of the strain detection element 26b, the longitudinal direction of the first beam-like vibrating body of the strain detection element 26a The amount of contraction in the longitudinal direction of the second beam-like vibrating body decreases. Therefore, the amount of change in the difference Δ between the vibration frequency of the first beam-like vibrating body of the strain detection element 26a and the vibration frequency of the second beam-like vibrating body is smaller than in the previous case. On the other hand, the distance between the working point of the strain detection element 26b and the compression load F 3 is shortened, with the longitudinal direction of elongation of the first beam-like vibrating body of the strain detection element 26b is increased, the second The amount of contraction in the longitudinal direction of the beam-like vibrating body also increases. Therefore, the amount of change in the difference Δ ′ between the vibration frequency of the first beam-like vibrating body of the strain detecting element 26b and the vibration frequency of the second beam-like vibrating body increases.

前記第1の側面22b上で同一の圧縮荷重F3を加える位置を、前記歪検出素子26aから歪検出素子26bの方向にさらに移動させると、歪検出素子26aの第1の梁状の振動体の振動周波数と、第2の梁状の振動体の振動周波数との差Δの変化量はさらに小さくなるとともに、歪検出素子26bの第1の梁状の振動体の振動周波数と、第2の梁状の振動体の振動周波数との差Δ′の変化量はさらに大きくなる。そして、前記第1の側面22b上で同一の圧縮荷重F3を、前記歪検出素子26bの背面中央に当る位置に加えると、歪検出素子26bの第1の梁状の振動体の振動周波数と、第2の梁状の振動体の振動周波数との差Δ′の変化量は最大となる。一方、前記歪検出素子26aの第1の梁状の振動体の振動周波数と、第2の梁状の振動体の振動周波数との差Δの変化量はほぼ零に等しくなる。 When the position where the same compressive load F 3 is applied on the first side surface 22b is further moved in the direction from the strain detecting element 26a to the strain detecting element 26b, the first beam-like vibrating body of the strain detecting element 26a. The amount of change in the difference Δ between the vibration frequency of the first beam-like vibrator and the vibration frequency of the second beam-like vibrator is further reduced, and the vibration frequency of the first beam-like vibrator of the strain detection element 26b The amount of change in the difference Δ ′ from the vibration frequency of the beam-like vibrating body is further increased. When the same compressive load F 3 is applied to the position of the center of the back surface of the strain detecting element 26b on the first side surface 22b, the vibration frequency of the first beam-like vibrating body of the strain detecting element 26b is obtained. The amount of change in the difference Δ ′ from the vibration frequency of the second beam-like vibrating body is maximized. On the other hand, the amount of change in the difference Δ between the vibration frequency of the first beam-like vibrating body of the strain detection element 26a and the vibration frequency of the second beam-like vibrating body is substantially equal to zero.

本発明の実施の形態3における携帯情報機器は、前記第1の側面22b上に圧縮荷重F3を加えたときに、前記歪検出素子26aの第1の梁状の振動体の振動周波数と、第2の梁状の振動体の振動周波数との差Δの変化量および歪検出素子26bの第1の梁状の振動体の振動周波数と、第2の梁状の振動体の振動周波数との差Δ′の変化量とから圧縮荷重F3が加えられた位置を検出して携帯情報機器71の機能の少なくとも1つを制御するものである。以下、実験結果を示しながら、前記Δ、Δ′から圧縮荷重F3が加えられた位置を検出する方法を説明する。 In the portable information device according to the third embodiment of the present invention, when a compressive load F 3 is applied on the first side surface 22b, the vibration frequency of the first beam-like vibrating body of the strain detecting element 26a, The amount of change in the difference Δ from the vibration frequency of the second beam-shaped vibrating body, the vibration frequency of the first beam-shaped vibrating body of the strain detecting element 26b, and the vibration frequency of the second beam-shaped vibrating body. The position where the compression load F 3 is applied is detected from the change amount of the difference Δ ′, and at least one of the functions of the portable information device 71 is controlled. Hereinafter, a method for detecting the position where the compressive load F 3 is applied from the Δ and Δ ′ will be described with reference to the experimental results.

図6(a)(b)(c)は携帯情報機器71の第1の側面22b上の既知の位置に所定の圧縮荷重F3を加えたときの、前記Δ、Δ′を測定したものである。ここで、第1の梁状の振動体に沿う方向の長さがともに9mmである歪検出素子26a、26bを筐体22内の第1の側面22bに対向する面に中心間距離を20mmとして接着剤にて取付けているが、筐体22内に設けたプリント基板に歪検出素子26a、26bを装着し、これらの歪検出素子26a、26bと前記第1の側面22bとを機械的に接続するようにしてもよい。 FIGS. 6A, 6B, and 6C are obtained by measuring Δ and Δ ′ when a predetermined compressive load F 3 is applied to a known position on the first side surface 22b of the portable information device 71. FIG. is there. Here, the strain detection elements 26a and 26b whose length in the direction along the first beam-shaped vibrating body are both 9 mm are set to a surface facing the first side surface 22b in the housing 22 with a center-to-center distance of 20 mm. Although attached with an adhesive, the strain detection elements 26a and 26b are mounted on a printed circuit board provided in the housing 22, and the strain detection elements 26a and 26b and the first side surface 22b are mechanically connected. You may make it do.

図6(a)は第1の側面22b上で歪検出素子26aの背面中央に当る位置に圧縮荷重F3を50gr間隔で1000grまで加えたときの前記Δ、Δ′の変化を測定したものである。また、図6(b)は第1の側面22b上で2つの歪検出素子26a、26bの中央に当る位置に圧縮荷重F3を50gr間隔で1000grまで加えたときの前記Δ、Δ′の変化を測定したものである。同様にして、図6(c)は第1の側面22b上で歪検出素子26bの背面中央に当る位置に圧縮荷重F3を50gr間隔で1000grまで加えたときの前記Δ、Δ′の変化を測定したものである。これらの測定結果から、前記Δ、Δ′は1000grまでの圧縮荷重F3に対して、ほぼ線形に変化すると判断できる。すなわち、前記Δの初期値からの変化量δΔおよび前記Δ′の初期値からの変化量δΔ′は以下のような数式でモデル化できる。 FIG. 6A shows the change in Δ and Δ ′ measured when a compressive load F 3 is applied to the position corresponding to the center of the back surface of the strain detecting element 26a on the first side face 22b up to 1000 gr at intervals of 50 gr. is there. FIG. 6B shows changes in Δ and Δ ′ when a compressive load F 3 is applied to a position corresponding to the center of the two strain detection elements 26a and 26b on the first side face 22b up to 1000 gr at intervals of 50 gr. Is measured. Similarly, FIG. 6C shows changes in Δ and Δ ′ when a compressive load F 3 is applied up to 1000 gr at intervals of 50 gr on the first side surface 22 b at the position corresponding to the center of the back surface of the strain detecting element 26 b. It is measured. From these measurement results, it can be determined that Δ and Δ ′ change substantially linearly with respect to the compression load F 3 up to 1000 gr. That is, the change amount δΔ from the initial value of Δ and the change amount δΔ ′ from the initial value of Δ ′ can be modeled by the following mathematical formula.

Figure 2013102416

ここで、A(x)、B(x)は圧縮荷重F3が加えられる位置座標xのみの関数である。これらの式から Here, A (x) and B (x) are functions of only the position coordinate x to which the compression load F 3 is applied. From these equations

Figure 2013102416
Figure 2013102416

となる。ここで、C(x)は圧縮荷重F3を加える位置xのみの関数である。 It becomes. Here, C (x) is a function of only the position x to which the compression load F 3 is applied.

このことから、前記Δの初期値からの変化量δΔと、前記Δ′の初期値からの変化量δΔ′との比δΔ/δΔ′と圧縮荷重F3を加える位置との関係を予め測定して、較正図表を作成しておけば、第1の側面22b上に任意の圧縮荷重F3を加えたときのδΔと、δΔ′を測定することで圧縮荷重F3を加えられた位置が検出できることになる。 Therefore, the relationship between the ratio δΔ / δΔ ′ between the change amount δΔ from the initial value of Δ and the change amount δΔ ′ from the initial value of Δ ′ and the position where the compression load F 3 is applied is measured in advance. If a calibration chart is prepared, the position where the compressive load F 3 is applied is detected by measuring δΔ when an arbitrary compressive load F 3 is applied on the first side surface 22b and δΔ ′. It will be possible.

図7(a)は上記の較正図表を示す。この較正線は圧縮荷重F3をパラメータとして、圧縮荷重F3を加える位置xに対するδΔ/δΔ′を測定し、統計処理を行なって決定したものである。ここで、前記第1の側面22b上で前記歪検出素子26aの背面中央に当る部分を原点とし、歪検出素子26bに向かう方向を正にとっている。この較正図表において、xが10mm、すなわち第1の側面22b上で2つの歪検出素子26a、26bの中央に当る位置に近づくと、δΔ/δΔ′が急速に小さくなり分解能が悪くなるという問題点がある。 FIG. 7A shows the calibration chart described above. The calibration line compressive load F 3 as a parameter, to measure the .DELTA..delta / .DELTA..delta 'with respect to the position x applying a compressive load F 3, is obtained by determining by performing statistical processing. In this case, the portion of the first side surface 22b that is in the center of the back surface of the strain detection element 26a is set as the origin, and the direction toward the strain detection element 26b is positive. In this calibration chart, when x is 10 mm, that is, when the position approaches the center of the two strain detection elements 26a and 26b on the first side surface 22b, δΔ / δΔ ′ rapidly decreases and the resolution deteriorates. There is.

図7(b)はこの問題点を解決する方法の一例であり、δΔ/δΔ′が所定の値、たとえば1以下になった場合には、δΔ/δΔ′に代えてδΔ′/δΔをとるようにした較正図表である。この較正図表を用いて、第1の側面22b上に任意の圧縮荷重F3を加えたときのδΔと、δΔ′を測定し、δΔ/δΔ′が1以上であれば左側の軸でδΔ/δΔ′の値に対応する位置xを求め、δΔ/δΔ′が1以下であれば、δΔ′/δΔを計算して右側の軸でδΔ′/δΔに対応する位置xを求めれば圧縮荷重F3を加えられた位置が検出できることになる。 FIG. 7B shows an example of a method for solving this problem. When δΔ / δΔ ′ is a predetermined value, for example, 1 or less, δΔ ′ / δΔ is taken instead of δΔ / δΔ ′. It is a calibration chart made like this. Using this calibration chart, δΔ and δΔ ′ when an arbitrary compressive load F 3 is applied to the first side surface 22b are measured. If δΔ / δΔ ′ is 1 or more, δΔ / The position x corresponding to the value of δΔ ′ is obtained. If δΔ / δΔ ′ is 1 or less, δΔ ′ / δΔ is calculated, and if the position x corresponding to δΔ ′ / δΔ is obtained on the right axis, the compression load F The position to which 3 is added can be detected.

こうして得られた位置情報を用いて、携帯情報機器71の機能を制御してさらに多様な操作入力を行なうことができるものである。なお、3つ以上の歪検出素子を携帯情報機器の筐体の一面に互いに直線状に隣接させ、機械的に結合するように携帯情報機器の筐体内に配置してもよい。これにより、隣接する2つの歪検出素子間を押された位置を検出でき、さらに、多様な操作入力を行なうことができるものである。   By using the position information obtained in this way, the functions of the portable information device 71 can be controlled to perform various operation inputs. Note that three or more strain detection elements may be arranged in the casing of the portable information device so that they are linearly adjacent to each other on one surface of the casing of the portable information device and mechanically coupled. As a result, it is possible to detect the pressed position between two adjacent strain detection elements, and to perform various operation inputs.

In the portable information device 81 according to the fourth embodiment of the present invention, components having the same configurations as those of the portable information device 21 according to the first embodiment of the present invention described above are denoted by the same reference numerals. The description thereof is omitted. 8 (a) and 8 (b), the difference between the portable information device 81 in the fourth embodiment of the present invention and the portable information device 21 in the first embodiment of the present invention is that three strain detection elements 26a, 26b and 26c are arranged in the housing 22 of the portable information device 81 so as to be mechanically coupled to the back surface 22d. Further, these strain detection elements 26a, 26b, 26c are provided at positions corresponding to the apexes of a right triangle. The strain detection elements 26a, 26b, and 26c are vibrator type strain detection elements formed by finely processing a semiconductor substrate made of silicon or the like, and have the same configuration as in FIG. A vibrator and a second beam-like vibrator orthogonal to the first beam-like vibrator are provided.

図8(a)において、本発明の実施の形態4における携帯情報機器81の筐体22をたとえば、片手の親指と中指、薬指、小指で持ちながら、人指し指で前記背面22dに圧縮荷重F4を加えると、各歪検出素子26a、26b、26cの第1の梁状の振動体の振動周波数と、第2の梁状の振動体の振動周波数が変化する。この振動周波数変化量は圧縮荷重F4と圧縮荷重を加える二次元位置座標(x、y)の関数となるが、圧縮荷重F4に対して、ほぼ線形に変化するため、前記歪検出素子26a、26b、26cの第1の梁状の振動体の振動周波数と、第2の梁状の振動体の振動周波数との差Δの変化量を各々δΔ1、δΔ2、δΔ3とすれば、これらは以下のような数式でモデル化できる。 In FIG. 8A, while holding the housing 22 of the portable information device 81 in Embodiment 4 of the present invention with, for example, the thumb, middle finger, ring finger, and little finger of one hand, the compression load F 4 is applied to the back surface 22d with the index finger. In addition, the vibration frequency of the first beam-like vibrating body of each strain detection element 26a, 26b, 26c and the vibration frequency of the second beam-like vibrating body change. This amount of change in vibration frequency is a function of the compression load F 4 and the two-dimensional position coordinate (x, y) to which the compression load is applied, but changes almost linearly with respect to the compression load F 4 . , 26b, 26c, if the change amounts of the difference Δ between the vibration frequency of the first beam-like vibrating body and the vibration frequency of the second beam-like vibrating body are δΔ 1 , δΔ 2 , and δΔ 3 , respectively. These can be modeled by the following mathematical formula.

となる。ここで、C1(x)、C2(x)は圧縮荷重F4を加える二次元位置座標(x、y)のみの関数である。 It becomes. Here, C 1 (x) and C 2 (x) are functions of only two-dimensional position coordinates (x, y) to which the compression load F 4 is applied.

このことから、前記δΔ1とδΔ2との比δΔ1/δΔ2および前記δΔ2とδΔ3との比δΔ2/δΔ3と圧縮荷重F4を加える位置との関係を予め測定して、較正図表を作成しておけば、背面22d上に任意の圧縮荷重F4を加えたときのδΔ1、δΔ2、δΔ3を測定することで圧縮荷重F4を加えられた位置が検出できることになる。こうして得られた位置情報を用いて、携帯情報機器81の機能を制御してさらに多様な操作入力を行なうことができるものである。 Therefore, by previously measured the relationship between the position adding the .DELTA..delta 1 and .DELTA..delta 2 and the ratio δΔ 1 / δΔ 2 and the .DELTA..delta 2 and .DELTA..delta 3 ratio of δΔ 2 / δΔ 3 and the compression load F 4, If a calibration chart is prepared, the position where the compressive load F 4 is applied can be detected by measuring δΔ 1 , δΔ 2 , and δΔ 3 when an arbitrary compressive load F 4 is applied to the back surface 22d. Become. Using the position information obtained in this way, the functions of the portable information device 81 can be controlled to allow further various operation inputs.

なお、3つの歪検出素子を携帯情報機器の筐体の一面に一般的な三角形の頂点に当る位置に置いても同様の効果が得られるものである。また、4つ以上の歪検出素子を携帯情報機器の筐体の一面に一般的な多角形の頂点に当る位置に置くことにより、冗長度を増すことで圧縮荷重F4を加えられた位置がさらに精度よく検出できるものである。 It is to be noted that the same effect can be obtained by placing the three strain detection elements on one surface of the casing of the portable information device at a position corresponding to the vertex of a general triangle. In addition, by placing four or more strain detection elements on one surface of the casing of the portable information device at a position where it hits the apex of a general polygon, the position to which the compression load F 4 is applied is increased by increasing the redundancy. Further, it can be detected with high accuracy.

The description thereof is omitted. 9 (a) and 9 (b), the difference between the portable information device 91 in the fifth embodiment of the present invention and the portable information device 71 in the third embodiment of the present invention is that the strain detection elements 26a and 26b are different. It is mounted on the first main surface 92a of the substrate 92, and the second main surface 92b of the substrate 92 is mechanically connected to the inside of the first side surface 22b of the housing 22 using an adhesive or a screw.
