Description

本発明は操作入力装置、例えば、携帯電話機等に組み込まれる薄型の操作入力装置に関する。   The present invention relates to an operation input device, for example, a thin operation input device incorporated in a mobile phone or the like.

従来、携帯電話機等に組み込まれる操作入力装置としては、例えば、いわゆるトラックボール方式操作入力装置がある（特許文献１参照）。このトラックボール方式操作入力装置によれば、操作者の指による一回の回動操作で、例えば、携帯電話機の表示部であるモニター内で一定量のスクロールを行うことができ、あるいは、カーソルを一定量だけ移動できる。このため、１回の回動操作に基づくスクロール量あるいはカーソルの移動量を直感的に予測でき、使い勝手が良く、一般重要者から根強い支持を受けている。
一方、近時、携帯電話機等はより一層の小型化、特に、薄型化が要望されている。 Conventionally, as an operation input device incorporated in a mobile phone or the like, for example, there is a so-called trackball type operation input device (see Patent Document 1). According to this trackball type operation input device, for example, a certain amount of scrolling can be performed in a monitor which is a display unit of a mobile phone, or the cursor can be moved by a single turning operation by an operator's finger. Can move only a certain amount. For this reason, the amount of scrolling or the amount of movement of the cursor based on a single rotation operation can be intuitively predicted, is easy to use, and has received strong support from general important persons.
On the other hand, cellular phones and the like have recently been demanded for further miniaturization, in particular, thinning.

しかしながら、前述のトラックボール方式操作入力装置では、ボール状の操作受け部を必要とするので、ハウジングを所望の薄さまで薄型化しようとすると、ボール状操作受け部の直径を極めて小さくする必要がある。このため、所望の薄型の携帯電話機を得ようとすると、ボール状操作受け部が小さくなりすぎ、回動操作に伴う操作感覚が得にくくなるので、操作入力装置の薄型化に限界があった。   However, since the above-described trackball type operation input device requires a ball-shaped operation receiving portion, it is necessary to make the diameter of the ball-shaped operation receiving portion extremely small in order to reduce the thickness of the housing to a desired thickness. . For this reason, when trying to obtain a desired thin mobile phone, the ball-shaped operation receiving portion becomes too small, and it becomes difficult to obtain an operational feeling associated with the turning operation, so that there is a limit to thinning the operation input device.

本発明に係る操作入力装置の実施形態を図１ないし図９に従って説明する。
第１実施形態に係る操作入力装置は、図１ないし図５に図示するように、携帯電話機に適用した場合である。 An embodiment of an operation input device according to the present invention will be described with reference to FIGS.
The operation input device according to the first embodiment is applied to a mobile phone as shown in FIGS.

本実施形態に係る携帯電話機は、図１および図２に示すように、ハウジング１０と、前記ハウジング１０内に組み込まれたプリント基板２０と、前記ハウジング１０に操作可能に組み付けられた操作体３０とからなる。   As shown in FIGS. 1 and 2, the mobile phone according to the present embodiment includes a housing 10, a printed circuit board 20 incorporated in the housing 10, and an operation body 30 operably assembled to the housing 10. Consists of.

前記ハウジング１０は、表示部１１と、この表示部１１の下方側中央部に設けたすり鉢状凹所１２と、前記すり鉢状凹所１２の両側に配置された第１，第２入力スイッチ１３，１４とで構成され、前記すり鉢状凹所１２の底面に操作孔１５が設けられている。なお、前記すり鉢状凹所１２は円錐台形状だけでなく、例えば、四角錐台形状であってもよい。   The housing 10 includes a display unit 11, a mortar-shaped recess 12 provided at a lower central portion of the display unit 11, and first and second input switches 13 disposed on both sides of the mortar-shaped recess 12. 14 and an operation hole 15 is provided in the bottom surface of the mortar-shaped recess 12. The mortar-shaped recess 12 is not limited to a truncated cone shape, and may be a truncated pyramid shape, for example.

前記プリント基板２０は、図２に示すように、その上面に設けたドームスイッチ２１を覆うように設けたホルダー２２内に弾性支持体２３を介して操作体３０をスライド操作可能に弾性支持している一方、前記ドームスイッチ２１に対向する裏面にホール素子を内蔵するＩＣ２４が実装されている。なお、前記ドームスイッチ２１は必要に応じて設ければよく、必ずしも設ける必要はない。   As shown in FIG. 2, the printed circuit board 20 elastically supports an operating body 30 through an elastic support 23 in a holder 22 provided so as to cover a dome switch 21 provided on the upper surface thereof. On the other hand, an IC 24 incorporating a Hall element is mounted on the back surface facing the dome switch 21. The dome switch 21 may be provided as necessary, and is not necessarily provided.

前記操作体３０は、その上端部に操作受け部３１を有するとともに、前記操作受け部３１の直下に抜け止め用鍔部３２を一体成形してある。さらに、前記操作体３０は、前記鍔部３２の下方側に検出部である永久磁石３３を一体成形してあるとともに、その最下端に操作用突起３４を前記操作受け部３１と同一軸心上に設けてある。
そして、前記操作体３０は、前記ホルダー２２内に自己復帰するように弾性支持され、その上端部に設けた操作受け部３１を前記ハウジング１０の操作孔１５から操作可能に突出させている一方、その下端部に突設した操作用突起３４を前記ドームスイッチ２１に当接させている。このため、前記操作体３０に設けた検出部である永久磁石３３と、プリント基板２０の裏面に実装したＩＣ２４内の変換部であるホール素子とで操作検出ユニット３５が形成されている。 The operating body 30 has an operation receiving portion 31 at an upper end portion thereof, and a retaining collar portion 32 is integrally formed immediately below the operation receiving portion 31. Further, the operating body 30 is integrally formed with a permanent magnet 33 as a detecting portion on the lower side of the flange portion 32, and an operating projection 34 is provided at the lowermost end on the same axis as the operation receiving portion 31. Is provided.
The operating body 30 is elastically supported so as to be self-returned in the holder 22, and an operation receiving portion 31 provided at the upper end thereof protrudes from the operation hole 15 of the housing 10 so as to be operable. An operation protrusion 34 protruding from the lower end of the dome switch 21 is brought into contact with the dome switch 21. Therefore, an operation detection unit 35 is formed by a permanent magnet 33 that is a detection unit provided on the operation body 30 and a Hall element that is a conversion unit in the IC 24 mounted on the back surface of the printed circuit board 20.

したがって、図３に示すブロック図のように、検出部である永久磁石３３の磁力線がＩＣ２４に内蔵されたホール素子に検出され、その操作方向、操作量が操作検出ユニット３５から出力信号として出力され、これを外部機器に設けたマイクロコントローラ（図示せず）が演算処理し、前記表示部１１にスクロール表示あるいはカーソル移動として表示される。   Therefore, as shown in the block diagram of FIG. 3, the magnetic lines of force of the permanent magnet 33 serving as the detection unit are detected by the Hall element built in the IC 24, and the operation direction and operation amount are output from the operation detection unit 35 as output signals. This is processed by a microcontroller (not shown) provided in an external device and displayed on the display unit 11 as scroll display or cursor movement.

本実施形態では、前記操作体３０の上端部に形成した操作受け部３１の頂部は前記ハウジング１０の最外表面から突出していないので、落下等による誤動作を防止できるという利点がある。   In this embodiment, since the top part of the operation receiving part 31 formed in the upper end part of the operation body 30 does not protrude from the outermost surface of the housing 10, there is an advantage that malfunction due to dropping or the like can be prevented.

前記操作受け部３１は断面円弧形の半球形状であり、操作者の指が一回のスライド操作を行った場合に、一回の回動操作を行ったと感じる操作感覚が得られる表面形状となっている。 The operation receiving portion 31 has a hemispherical shape with a circular arc cross section, and when the operator's finger performs a single slide operation , a surface shape that provides an operational feeling that feels that the user has performed a single rotation operation ; It has become.

このため、前記操作受け部３１は、曲率半径が２．５ｍｍから１０．５ｍｍ、特に、３．５ｍｍから１０．５ｍｍが好適である。２．５ｍｍ未満であると、直径で５ｍｍ程度以下の細い突起に触れている感覚になるからであり、１０．５ｍｍを越えると、平坦面に近くなること、及び、突出量を大きくする場合に垂直に近い面が指に触れることになり、回動操作感が失われるからである。   For this reason, the operation receiving portion 31 preferably has a curvature radius of 2.5 mm to 10.5 mm, particularly 3.5 mm to 10.5 mm. If it is less than 2.5 mm, it becomes a sensation of touching a thin protrusion having a diameter of about 5 mm or less. If it exceeds 10.5 mm, it becomes close to a flat surface and the amount of protrusion is increased. This is because the surface close to vertical touches the finger and the feeling of rotation operation is lost.

また、前記操作受け部３１の操作孔１５の開口縁部からの突出量は０．３ｍｍから１．２ｍｍ、特に、０．５ｍｍから１．１ｍｍが好適である。０．３ｍｍ未満であると、触れられる面積が小さくなり、ボールやローラのような曲面と感じにくいからであり、１．２ｍｍを越えると、指に対する引っ掛かりが強くなり、曲面上をスムーズに滑らず、回動操作感を感じにくいからである。   Further, the projection amount of the operation receiving portion 31 from the opening edge portion of the operation hole 15 is preferably 0.3 mm to 1.2 mm, particularly 0.5 mm to 1.1 mm. If it is less than 0.3 mm, the touched area will be small, and it will be difficult to feel a curved surface like a ball or a roller. If it exceeds 1.2 mm, the finger will be caught more strongly and will not slide smoothly on the curved surface. This is because it is difficult to feel the rotational operation.

さらに、前記操作受け部３１のスライド量は１．１ｍｍ以下、特に、０．３ｍｍ以上、１．１ｍｍ以下が好適である。０．３ｍｍ未満であると、組立誤差等による位置決め精度のバラツキにより、誤検出するおそれがあるからであり、１．１ｍｍを越えると、操作者の半数以上がスライド操作していると感じてしまうからである。   Furthermore, the sliding amount of the operation receiving portion 31 is preferably 1.1 mm or less, particularly 0.3 mm or more and 1.1 mm or less. If it is less than 0.3 mm, there is a risk of erroneous detection due to variations in positioning accuracy due to assembly errors or the like, and if it exceeds 1.1 mm, more than half of the operators will feel that they are performing a slide operation. Because.

そして、前記操作受け部３１の表面粗さＲａ（算術平均粗さ）は０．５μｍ以下であれば、適度な摩擦によって好ましい回動操作感が得られる。特に、０．１〜０．２μｍの鏡面に近い状態であれば、回動操作感がより一層、得やすくなる。   And if the surface roughness Ra (arithmetic mean roughness) of the said operation receiving part 31 is 0.5 micrometer or less, a preferable rotational operation feeling will be obtained by moderate friction. In particular, in a state close to a mirror surface of 0.1 to 0.2 μm, it becomes easier to obtain a feeling of turning operation.

前述の構成からなる操作入力装置の操作過程を図４および図５の添付図面について具体的に説明する。
すなわち、図４に示すように、操作者の指４０が操作入力装置の操作受け部３１に対して非接触状態（操作位置（i））から操作受け部３１に接触し、操作を開始すると（操作位置（ii））、前記操作受け部３１がスライド移動して操作孔１５の開口縁部に当接する（操作位置（iii））。ついで、操作者の指４０が操作受け部３１の表面を滑り（操作位置（iv）,(ｖ)）、操作者の指４０が操作受け部３１から離れると、前記操作受け部３１が自己復帰力で元の位置に復帰する（操作位置（vi））。このとき、操作時間が短時間であるとともに、操作者の指４０が操作受け部３１の表面を滑ることにより、操作者の指４０はスライド操作しているにも拘わらず、回動操作していたという操作感覚を感じる。 The operation process of the operation input device having the above-described configuration will be specifically described with reference to FIGS. 4 and 5.
That is, as shown in FIG. 4, when the operator's finger 40 comes into contact with the operation receiving portion 31 from the non-contact state (operation position (i)) with respect to the operation receiving portion 31 of the operation input device and starts the operation ( The operation position (ii)), the operation receiving portion 31 slides and comes into contact with the opening edge of the operation hole 15 (operation position (iii)). Next, when the operator's finger 40 slides on the surface of the operation receiving portion 31 (operation positions (iv), (v)) and the operator's finger 40 moves away from the operation receiving portion 31, the operation receiving portion 31 self-resets. Return to the original position with force (operating position (vi)). At this time, the operation time is short, and the operator's finger 40 slides on the surface of the operation receiving portion 31, so that the operator's finger 40 is rotated while being slid. I feel the operation feeling that was.

前述の操作過程をグラフ図および表示部の変化で説明すると、図５に示すように、操作位置（i）の場合には、永久磁石３３が変位していないので、出力信号が出力されず、スクロール表示の変動、あるいは、カーソル１６の移動も行われない。そして、操作位置（ii）になると、永久磁石３３が変位を開始し、出力信号が出力されて閾値を超えるが、出力信号が所定の数値に達するまでスクロール表示の変動、あるいは、カーソル１６の移動は行われない。さらに、操作者の指４０が操作受け部３１を移動させることにより、操作受け部３１がハウジング１０の操作孔１５の開口縁部に当接する操作位置（iii）まで移動すると、出力信号が最大値に達し、スクロール表示が「ＡＡＡ」から「ＢＢＢ」まで移動し、あるいは、カーソル１６が表示位置（ｉ），(ii)から表示位置（iii）まで移動する。   The above-described operation process will be described with reference to a graph and a change in the display unit. As shown in FIG. 5, in the case of the operation position (i), the permanent magnet 33 is not displaced, so no output signal is output. The scroll display is not changed or the cursor 16 is not moved. When the operation position (ii) is reached, the permanent magnet 33 starts to be displaced, and an output signal is output and exceeds the threshold value. However, the scroll display changes or the cursor 16 moves until the output signal reaches a predetermined value. Is not done. Further, when the operator's finger 40 moves the operation receiving portion 31 and the operation receiving portion 31 moves to the operation position (iii) where it abuts against the opening edge of the operation hole 15 of the housing 10, the output signal becomes the maximum value. The scroll display moves from “AAA” to “BBB”, or the cursor 16 moves from the display position (i), (ii) to the display position (iii).

操作受け部３１が操作孔１５の開口縁部に当接したままの状態で操作者の指４０が操作受け部３１の表面を滑るので、操作受け部３１の操作位置（iv），（ｖ）を維持しつつ、最大出力信号を出力し続ける。このため、スクロール表示が「ＢＢＢ」から「ＣＣＣ」，「ＤＤＤ」まで移動し、あるいは、カーソル１６が表示位置（iii）から表示位置（iv），（ｖ）まで移動する。   Since the operator's finger 40 slides on the surface of the operation receiving portion 31 while the operation receiving portion 31 remains in contact with the opening edge of the operation hole 15, the operation positions (iv) and (v) of the operation receiving portion 31 are maintained. While maintaining the maximum output signal. Therefore, the scroll display moves from “BBB” to “CCC”, “DDD”, or the cursor 16 moves from the display position (iii) to the display positions (iv), (v).

そして、操作位置（vi）で指が操作受け部３１から離れると、操作体３０が自己復帰力で元の位置に復帰し、出力信号が急激に低減し、スクロール表示が「ＤＤＤ」で停止し、あるいは、カーソルが表示位置（vi）で停止する。   When the finger is moved away from the operation receiving portion 31 at the operation position (vi), the operation body 30 returns to the original position by the self-returning force, the output signal rapidly decreases, and the scroll display stops at “DDD”. Or, the cursor stops at the display position (vi).

本実施形態よれば、操作者の指４０は操作受け部３１をスライド操作しているにも拘わらず、操作者の指４０は操作受け部３１を回動操作しているように感じることができる。このため、操作者は、一回のスライド操作で一定量のスクロール移動、あるいは、一定量のカーソル移動を直感的に把握でき、操作しやすいと感じる。   According to the present embodiment, the operator's finger 40 can feel as if the operator's finger 40 is turning the operation receiver 31 even though the operator's finger 40 is slidingly operating the operation receiver 31. . For this reason, the operator can intuitively grasp a certain amount of scroll movement or a certain amount of cursor movement by one slide operation, and feels that the operation is easy.

第２実施形態は、図６に示すように、縦方向の軸心を有する半円柱形状の操作受け部３１を有する操作入力装置である。このため、操作者は前記操作受け部３１を左右にスライド操作させた場合であっても、前記操作受け部３１を左右方向に回動操作しているという操作感覚を感じつつ、直感的に一回の操作量を正確に認識できるという利点がある。   The second embodiment is an operation input device having a semi-cylindrical operation receiving portion 31 having a longitudinal axis as shown in FIG. For this reason, even when the operator slides the operation receiving portion 31 to the left and right, the operator feels the operational feeling that the operation receiving portion 31 is rotated in the left and right direction, and intuitively makes one. There is an advantage that the operation amount can be accurately recognized.

第３実施形態は、図７に示すように、基本的構成は前述の第２実施形態と同様であり、異なる点は操作受け部３１の外周面に沿って所定のピッチで複数本の横溝３６を設けた点である。
本実施形態によれば、横溝３６を設けてあるので、操作受け部３１の操作方向が直感的に分かりやすくなり、左右方向の回動操作をより一層強く感じることができるという利点がある。 As shown in FIG. 7, the basic configuration of the third embodiment is the same as that of the second embodiment described above. The difference is that a plurality of lateral grooves 36 are arranged at a predetermined pitch along the outer peripheral surface of the operation receiving portion 31. This is the point.
According to the present embodiment, since the lateral groove 36 is provided, there is an advantage that the operation direction of the operation receiving portion 31 can be easily understood intuitively and the left / right rotation operation can be felt more strongly.

第４実施形態は、図８に示すように、横方向の軸心を有する半円柱形状の操作受け部３１を有する操作入力装置である。このため、操作者は前記操作受け部３１を上下にスライド移動させているにも拘わらず、前記操作受け部３１を上下方向に回動操作しているという操作感覚を感じつつ、直感的に一回の操作量を正確に認識できるという利点がある。   As shown in FIG. 8, the fourth embodiment is an operation input device having a semi-cylindrical operation receiving portion 31 having a lateral axis. For this reason, the operator feels the operational feeling that the operation receiving portion 31 is rotated up and down despite the fact that the operation receiving portion 31 is slid up and down. There is an advantage that the operation amount can be accurately recognized.

第５実施形態は、図９に示すように、基本的構成は前述の第４実施形態と同様であり、異なる点は操作受け部３１の外周面に沿って所定のピッチで複数本の縦溝３７を設けた点である。
本実施形態によれば、縦溝３７を設けてあるので、操作受け部３１の操作方向が直感的に分かりやすくなり、上下方向の回動操作としてより一層強く感じることができるという利点がある。 As shown in FIG. 9, the fifth embodiment has the same basic configuration as that of the fourth embodiment described above, except that a plurality of vertical grooves are formed at a predetermined pitch along the outer peripheral surface of the operation receiving portion 31. 37 is provided.
According to the present embodiment, since the vertical groove 37 is provided, there is an advantage that the operation direction of the operation receiving portion 31 can be easily understood intuitively and can be felt more strongly as a vertical rotation operation.

図１０に図示するように、指４０でスライド操作したにも拘わらず、回動操作した感じた人数と、操作受け部３１の突出量、曲率半径またはスライド操作量との相関関係を知るべく、２０人の被験者に対して実験を行った。測定結果を図１１および図１２に示す。
なお、図１１において１つの方形ドットは被験者２０人のうち、半数以上が回動操作したと感じた場合を示す。 As shown in FIG. 10, in order to know the correlation between the number of people who felt the rotation operation in spite of the slide operation with the fingers 40 and the protrusion amount, the curvature radius, or the slide operation amount of the operation receiving portion 31, Experiments were performed on 20 subjects. The measurement results are shown in FIGS.
In addition, in FIG. 11, one square dot shows the case where more than half of 20 test subjects felt that the rotation operation was performed.

図１１に図示するように、操作受け部３１が曲率半径２．５ｍｍ〜１０．５ｍｍで、かつ、突出量０．３ｍｍ〜１．２ｍｍであれば、被験者２０人のうち、半数以上が回動操作していると感じることが分かった。   As shown in FIG. 11, when the operation receiving portion 31 has a radius of curvature of 2.5 mm to 10.5 mm and a protrusion amount of 0.3 mm to 1.2 mm, more than half of the 20 subjects rotate. I found that I felt that I was operating.

図１２に図示するように、スライド操作量が１．１ｍｍ以内であれば、被験者の半数以上がスライド操作していると感じないことが判った。なお、スライド操作量が０．３ｍｍ未満であると、操作受け部３１の組立誤差等に基づく位置決め精度のバラツキにより、誤検出する場合があり、０．３ｍｍ以上のスライド操作量は必要である。   As shown in FIG. 12, when the slide operation amount is within 1.1 mm, it has been found that more than half of the subjects do not feel that the slide operation is performed. If the slide operation amount is less than 0.3 mm, erroneous detection may occur due to variations in positioning accuracy based on assembly errors of the operation receiving portion 31, and a slide operation amount of 0.3 mm or more is necessary.

また、スライド操作量が０．３ｍｍないし１．１ｍｍの場合には、操作速度にもよるが１回当たりの操作時間が０．５秒ないし３秒程度であれば、スライド操作と感じないと考えられる。   Also, when the slide operation amount is 0.3 mm to 1.1 mm, although it depends on the operation speed, if the operation time per operation is about 0.5 seconds to 3 seconds, it is considered that the slide operation is not felt. It is done.

本願発明に係る操作入力装置は、携帯電話機に適用する場合に限らず、ポータブルプレーヤー、デジタルカメラ等に適用してもよいことは勿論である。   Of course, the operation input device according to the present invention may be applied not only to a mobile phone but also to a portable player, a digital camera, and the like.
