Description

この関係を利用することにより、図４（ａ）の矢印に示すように、静電モータ１０の駆動方向を逆転させる場合、印加する電圧の位相を逆進させればよい。静電モータ１０の駆動変位ｘを時間ｔの複雑な関数ｘ＝ｆ（ｔ）とする場合であっても前記関係式は成立し、例えば駆動変位ｘと時間ｔとの関係を図３（ａ）に示した周期関数とする場合、３相電圧は図４（ｂ）に示すような位相変化となるよう制御される。
【００１６】
次に、このような構成からなる本実施の形態の作用について説明する。印加装置１４は、予め設定された往復駆動変位ｘに基づいて制御された３相電圧を接続回路１３を介して固定子１１の３相帯状電極１１ａ、１１ｂ、１１ｃおよび振動子１２の３相帯状電極１２ａ、１２ｂ、１２ｃに印加する。振動子１２は、印加される電圧に従って固定子１１に対してｘ変位する。このため、振動子１２に固着された振動搬送路５は振動子１２の往復変位に伴って往復変位する、すなわち振動する。この場合、時間と駆動変位との関係が往復で非対称であれば、振動搬送路５上に搬送物Ｐを載せると当該振動によって搬送物Ｐが搬送される。
【００１７】
以上のように本実施の形態によれば、静電モータ１０の振動子１２と振動搬送路５とを固着することにより、振動搬送路５の振動方向を振動搬送路５の方向（面方向）に容易に合わせることができ、振動搬送路５上の搬送物Ｐが跳ね上がって搬送物Ｐが破損するという問題が回避される。また、静電モータ１０の駆動力は電極１１ａ、１１ｂ、１１ｃ、１２ａ、１２ｂ、１２ｃの面積に比例するため、駆動力の大きい静電モータ１０であっても小型、薄型で軽量であるため、装置全体も小型で軽量である。
【００１８】
本実施の形態は特に、紙、カード、ディスク等のシート状物体の搬送において利点を有する。これらの搬送装置としては、図１２に示すようにローラ１０５と通常のモータ１０６とベルト１０７によるカードＣの搬送装置が知られているが、本発明による振動式搬送装置１を利用してカードＣを搬送することにより装置の著しい小型・薄型化を図ることができる。例えば、プリンタ、コピー機、カードリーダ、ディスクドライブ等の装置において、本発明による振動式搬送装置１を用いると、図１３および図１４に示すように各装置は著しく小型・薄型化され得る。さらに本発明による振動式搬送装置１は、粉体や各種の搬送物Ｐの搬送においても同様に利点を有する。
【００１９】
ところで搬送物Ｐの搬送は、搬送物Ｐと振動搬送路５との相互作用、具体的には摩擦力や静電気による静電吸引力に依存する。従って例えば搬送物Ｐの摩擦係数の相違を利用することによって、本発明による振動式搬送装置１を分離機構や分級機構として利用することも可能である。この場合、時間と振動子１２の駆動変位との関係を、例えば図３（ｂ）のように制御する。
【００２０】
次に、図５を用いて、本発明による振動式搬送装置の他の実施の形態について説明する。図５に示すように本実施の形態においては、静電モータ１０の振動子１２の電極（スキューされた帯状電極）１２ｄ、１２ｅ、１２ｆを、Ｖ字形状にスキューされている点が異なるのみであり、その他の構成は図１乃至図４に示す実施の形態と略同様である。
【００２１】
図５において、図１乃至図４に示す実施の形態と同一部分には同一符号を付して詳細な説明は省略する。
【００２２】
図５に示す実施の形態において、振動子１２の電極１２ｄ、１２ｅ、１２ｆがスキューされていることにより、〔数１〕に示した振動子１２の駆動変位と印加電圧の位相との対応関係がより精度良く現れるため、より安定に振動子１２の駆動を制御することができる。従って、図１乃至図４に示した実施の形態による効果に加えて、静電モータ１０の駆動変位の制御性が大幅に向上する（電気学会論文誌Ｄ、１１７巻３号、平成９年、ｐｐ．３７３―３７８参照）。
【００２３】
次に、図６を用いて、本発明による振動式搬送装置の更に他の実施の形態について説明する。図６に示すように本実施の形態においては、静電モータ２０は、内部に互いに平行かつ周期的に配置された１相帯状電極２１ａを有する面状の固定子２１と、内部に２相帯状電極２２ａ、２２ｂを有する面状の振動子２２とを備えている。振動子２２の２相帯状電極２２ａ、２２ｂは、振動子２２を中央で２分した領域に分かれて設けられている。また２相帯状電極２２ａ、２２ｂを構成する各電極２２ａ、２２ｂは、振動子２２の両側の領域においてそれぞれ平行かつ周期的に配置され、各電極２２ａ、２２ｂのみをみると、１相帯状電極と同様の構造となっている。またいずれの２相帯状電極２２ａ、２２ｂも、対応する固定子２１の１相帯状電極２１ａに対して外側にずれた位置に対向して配置されている。さらに静電モータ２０は、接続回路２３と、３相電圧を発生させて接続回路２３を介して固定子２１の１相帯状電極２１ａおよび振動子２２の２相帯状電極２２ａ、２２ｂに印加する印加装置２４とを有するが、その他の構成は図１乃至図４に示す実施の形態と略同様である。
【００２４】
図６に示す静電モータ２０を有する実施の形態の作用について以下に説明する。図６に示す実施の形態によれば、印加装置２４によって各帯状電極２１ａ、２２ａ、２２ｂに通常の３相交流電圧（３相正弦波電圧）が印加され、この３相交流電圧によって振動子２２が振動する。このため、静電モータ２０の駆動制御のための電圧の設定および印加がより容易となり、静電モータ２０の駆動回路が簡略化できる。
【００２５】
次に、図７を用いて、本発明による振動式搬送装置の更に他の実施の形態について説明する。図７に示すように本実施の形態においては、静電モータ３０は、内部に互いに平行かつ周期的に配置された２相帯状電極３１ａ、３１ｂを有する平面状の固定子３１と、内部に互いに平行かつ周期的に配置された１相帯状電極３２ａを有する平面状の振動子３２とを備えている。このうち振動子３２の１相帯状電極３２ａは、対応する固定子３１の２相帯状電極３１ａ、３１ｂの中間位置に対向して配置されている。さらに静電モータ３０は、接続回路３３と、３相電圧を発生させて接続回路３３を介して各帯状電極３１ａ、３１ｂ、３２ａに印加する印加装置３４とを有するが、その他の構成は図１乃至図４に示す実施の形態と同様である。
【００２６】
図７に示す実施の形態によれば、図６に示す実施の形態の場合と同様、印加装置３４によって各電極３１ａ、３１ｂ、３２ａに通常の３相交流電圧（３相正弦波電圧）が印加され、このことによって振動子３２が振動する。このため、静電モータ３０の駆動制御のための電圧の設定および印加がより容易となり、静電モータ３０の駆動回路が簡略化できる。
【００２７】
次に、図８を用いて、本発明による振動式搬送装置の更に他の実施の形態について説明する。図８に示すように本実施の形態においては、静電モータ４０は、内部に互いに平行かつ周期的に配置された１相帯状電極４１ａを有する平面状の固定子４１と、内部に互いに平行かつ周期的に配置された１相帯状電極４２ａを有する平面状の振動子４２とを備えている。
【００２８】
図８において、固定子４１の１相帯状電極４１ａと振動子４２の１相帯状電極４２ａとは互いに対向する位置であって、帯状電極４１ａ、４２ａが延びる方向と直交する方向（図８の左右方向）にずれて配置されている。また固定子４１と振動子４２との間には、弾性体４５が設けられている。さらに静電モータ４０は、接続回路４３と、電圧を発生させて接続回路４３を介して固定子４１の１相帯状電極４１ａおよび振動子４２の１相帯状電極４２ａに印加する印加装置４４とを有するが、その他の構成は図１乃至図４に示す実施の形態と同様である。
【００２９】
図８において、印可装置４４によって帯状電極４１ａおよび帯状電極４２ａのうちの一方に通常の交流電圧（正弦波電圧）が印加され、帯状電極４１ａおよび帯状電極４２ａのうちの他方に電圧ゼロが印加される（接地される）と、固定子４１と振動子４２とが互いに変位するが、この変位は弾性体４５の復元力によって復元し、このようにして振動子４２が振動する。図８に示す実施の形態によれば、印加装置４４によって帯状電極４１ａと帯状電極４２ａとに通常の交流電圧（正弦波電圧）と接地電圧とを印加することによって振動子４２を振動させることができるため、静電モータ４０の駆動制御のための電圧の設定および印加がより容易となり、静電モータ４０の駆動回路が簡略化できる。
【００３０】
図９は、本発明による振動式搬送装置の更に他の実施の形態を示す構成図である。本実施の形態では、静電モータ５０が帯状電極５１ａ、５１ｂ、５１ｃを有する固定子５１と、帯状電極５２ａ、５２ｂ、５２ｃを有する振動子５２とを備え、振動子５２がそのまま延長されてその延長部が振動搬送路５５を形成している点が異なるのみであり、その他の構成は図１乃至図４に示す実施の形態と略同様である。
【００３１】
図９に示す実施の形態によれば、静電モータ５０の振動子５２の延長部が振動搬送路５５を形成するとともに、振動子５２の振動方向と振動搬送路５５の配置方向が一致するため、制御性が向上するとともに装置全体の一層の小型化を図ることができる。
【００３２】
図１０は、本発明による振動式搬送装置の他の実施の形態を示す構成図である。本実施の形態では、静電モータ６０が帯状電極６１ａ、６１ｂ、６１ｃを有する固定子６１と、帯状電極６２ａ、６２ｂ、６２ｃを有する振動子６２とを備え、振動子６２の電極６２ａ、６２ｂ、６２ｃの上部に電界を遮蔽する遮蔽板６６が一直線状（平板状）に一体に設けられている点が異なるのみであり、その他の構成は図９に示す実施の形態と略同様である。図１０において遮蔽板６８は、通常の電極板で構成されている。また図１０において振動子６２の延長部は振動搬送路６５を形成している。
【００３３】
図１０に示す実施の形態によれば、静電モータ６０の固定子６１の帯状電極６１ａ、６１ｂ、６１ｃおよび振動子６２の帯状電極６２ａ、６２ｂ、６２ｃへの電圧の印加に伴って発生する電界の搬送物Ｐへの影響を回避することが可能である。搬送物Ｐの誘電率や導電率によっては、静電モータ６０の電極６１ａ、６１ｂ、６１ｃ、６２ａ、６２ｂ、６２ｃへの電圧の印加の影響から搬送物Ｐおよび振動式搬送装置が予想外の挙動を示す恐れがあるため、この効果は極めて重要である。
【００３４】
図１１は、本発明による振動式搬送装置の更に他の実施の形態を示す構成図である。本実施の形態では、静電モータ７０が帯状電極７１ａ、７１ｂ、７１ｃを有する固定子７１と、帯状電極７２ａ、７２ｂ、７２ｃを有する振動子７２とを備え、振動子７２内の帯状電極７２ａ、７２ｂ、７２ｃの上部に遮蔽板７６が一直線上に設けられ、さらに遮蔽板７６の上部に静電吸引用電極７７が一体に設けられている点が異なるのみであり、その他の構成は図９に示す実施の形態と略同様である。図１１に示す静電吸引用電極７７は、平行かつ周期的な２相帯状吸引用電極７７ａとして構成され（図１２（ａ）参照）、接続回路７８を介して静電吸引用電源７９に接続されている。なお図１２（ｂ）に示すように、静電吸引用電極７７を平面状吸引用電極７７ｂとして構成してもよい。また図１１において、振動子７２の延長部は振動搬送路７５を形成している。
【００３５】
図１１に示す実施の形態によれば、図１０に示す実施の形態による効果に加えて、静電吸引用電極７７に適当な電圧を印加して振動搬送路７５と搬送物Ｐとの間の静電吸引力を調整することによって、搬送物Ｐの搬送効率をより向上させることが可能である。さらには、図１３に示す態様により本実施の形態による振動式搬送装置１を利用する場合、積み重ねられた複数枚の用紙（一般に導電性を有する）のうち最上段の１枚のみに静電吸引力を働かせて用紙を分離することも可能である。
【００３６】
本実施の形態においては、静電吸引用電極７７へ周期的変化をさせて電圧を印加してもよく、一定の電圧を印加し続けるだけでもよい。この場合静電吸引用電極７７と遮蔽板７６とを一体化することも可能である。尚、静電吸引用電極７７は、振動子７２の電極７２ａ、７２ｂ、７２ｃに対応する領域のみに設ける必要はなく、さらに延長して搬送路７５の全長にわたって設けても良い。
【００３７】
尚、以上に示した実施の形態は、静電モータ１０、２０、３０、４０、５０、６０、７０がいずれも直線往復駆動するものであるが、静電モータ１０、２０、３０、４０、５０、６０、７０を構成する固定子１１、２１、３１、４１、５１、６１、７１および振動子１２、２２、３２、４２、５２、６２、７２は前述したようにフレキシブルフィルム状に構成できるため、図１５に示すように、静電モータ１０、２０、３０、４０、５０、６０、７０を例えば円弧状等の湾曲した構造とすることが可能である。この場合、静電モータ１０、２０、３０、４０、５０、６０、７０の往復駆動方向も円弧状等となるため、静電モータ１０、２０、３０、４０、５０、６０、７０の駆動方向に沿って円弧状に湾曲した振動搬送路５、５５、６５、７５を形成することができる。
【００３８】
また、静電モータ１０、２０、３０、４０、５０、６０、７０および振動搬送路５、５５、６５、７５の断面形状についても、平面でなくＵ字状等の湾曲形状に構成することも可能である。さらに発展して、図１６に示すように、静電モータ１０、２０、３０、４０、５０、６０、７０の固定子１１、２１、３１、４１、５１、６１、７１と振動子１２、２２、３２、４２、５２、６２、７２とを直径の異なる円筒状に構成することもできる。この場合、固定子１１、２１、３１、４１、５１、６１、７１および振動子１２、２２、３２、４２、５２、６２、７２の各電極１１ａ、１１ｂ、１１ｃ、１２ａ、１２ｂ、１２ｃ、１２ｄ、１２ｅ、１２ｆ、２１ａ、２２ａ、２２ｂ、３１ａ、３１ｂ、３２ａ、４１ａ、４２ａ、５１ａ、５１ｂ、５１ｃ、５２ａ、５２ｂ、５２ｃ、６１ａ、６１ｂ、６１ｃ、６２ａ、６２ｂ、６２ｃ、７１ａ、７１ｂ、７１ｃ、７２ａ、７２ｂ、７２ｃは、らせん状に構成され得る。なお、図１６において振動搬送路５、５５、６５、７５はＵ字状であるが、振動搬送路５、５５、６５、７５を円筒状とすることも可能である。
【００３９】
さらに静電モータが回転往復駆動する場合の実施の形態について、図１７に示す。図１７は、本発明による振動式搬送装置の更に他の実施の形態を示す構成図である。本実施の形態では、円形静電モータ８０が放射状帯状電極８１ａ、８１ｂ、８１ｃを有する円形固定子８１と、放射状帯状電極８２ａ、８２ｂ、８２ｃを有する円形振動子８２とを備え、振動子８２がそのまま振動搬送路８５を形成している点が異なるのみであり、その他の構成は図１乃至図４に示す実施の形態と略同様である。
【００４０】
図１７に示す実施の形態によれば、円形静電モータ８０はその中心からの距離に応じて駆動変位が異なるため、特に分離、分級、の用途への利用が期待される。
【００４１】
さらに２以上の駆動方向を有する実施の形態について、図１８に示す。図１８は、本発明による振動式搬送装置の更に他の実施の形態を示す構成図である。本実施の形態では、方形静電モータ９０が帯状電極９１ａ、９１ｂ、９１ｃによる第１電極群Ｆと、第１電極群Ｆの電極と直交する帯状電極９１ｄ、９１ｅ、９１ｆによる第２電極群Ｓとを有する固定子９１と、固定子９１の各電極９１ａ〜９１ｆに対応する帯状電極９２ａ〜９２ｆを有する振動子９２とを備え、振動子９２がそのまま振動搬送路９５および振動搬送路９５’を形成している点が異なるのみであり、その他の構成は図１乃至図４に示す実施の形態と略同様である。
【００４２】
図１８に示す実施の形態によれば、静電モータ９０は第１電極群Ｆと第２電極群Ｓとによる２方向の駆動が可能であるので、これらを交互に駆動することにより、振動搬送路９５と振動煩労路９５’とを任意に選択することができる。さらには、振動子９２上の任意の位置に搬送物Ｐを搬送することも可能である。
【００４３】
【発明の効果】
以上のように本発明によれば、装置全体が極めて薄型で、小型かつ軽量であるため、従来装置と比較して取り扱いおよび設置が容易である。
【００４４】
また本発明は、薄型かつ軽量であるため、プリンタ、コピー機、カードリーダ、ディスクドライブ等の装置においてシート状物体の搬送に利用することにより、各装置の著しい小型化を可能にする。
【００４５】
さらに本発明は、粉体や各種の搬送物の搬送においても同様の利点を有する。また本発明は、搬送物と振動搬送路との摩擦係数の相違を利用することによって、分級機構として利用することも可能である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vibration-type transfer device that places an object on a vibrating vibration surface and conveys or separates the object on the vibration surface by utilizing the interaction between the vibration surface and the object.
[0002]
[Prior art]
As shown in FIG. 19, the conventional vibration-type transfer device includes a vibrating device 100 that excites vibration, and a vibrating body 101 that is connected to the vibrating device 100 and that applies vibration and friction to the conveyed object P. ing. The vibration device 100 includes a displacement generating mechanism such as an electromagnetic solenoid or a piezoelectric element, and a leaf spring.
[0003]
[Problems to be solved by the invention]
2. Description of the Related Art A conventional vibration-type transfer device is used, for example, in a component supply line of an assembly plant, and is called a “vibration part feeder”. In principle, any object can be transported, but in practice, its use is limited to the supply of parts and the supply of powder and the like in a factory. This is considered to be because the conventional vibration-type transfer device has an electromagnetic solenoid or the like, and is large and heavy and difficult to handle.
[0004]
Further, it is difficult for the conventional vibration-type transfer device to configure the vibration direction and the surface direction of the vibrating body 101 in the same direction, and in practice, the vibration direction has a certain angle with respect to the surface of the vibrating body 101. ing. For this reason, in the conventional vibratory transfer apparatus, when the vibration frequency or the vibration amplitude is increased in order to improve the transfer speed, the transfer object P during transfer may jump on the vibrating body 101, and the transfer object may be damaged. There is a problem that the vibration of the vibrating body 101 is disturbed or noise is generated.
[0005]
The present invention has been made in view of such a point, and is smaller, thinner and lighter than the conventional configuration, and can easily arbitrarily determine the relationship between the vibration direction and the plane direction of the vibrating body. It is an object of the present invention to provide a vibrating transfer device that can be configured.
[0006]
[Means for Solving the Problems]
The present invention includes a vibration device, and a vibration conveyance path mechanically connected to the vibration device and forming a conveyance path, wherein the vibration device has an electrostatic motor that reciprocates. And a vibration-type transfer device.
[0007]
According to the present invention, since the vibration device has an electrostatic motor and is small, thin, and lightweight, it is possible to reduce the size and weight of the entire vibration type transport device. In addition, since the surface direction of the vibration conveyance path and the driving direction of the electrostatic motor can be arbitrarily adjusted, for example, by providing the vibration conveyance path in the driving direction of the electrostatic motor, the vibration conveyance path is moved in the direction of the vibration conveyance path. It can be easily vibrated along.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram showing one embodiment of a vibration type transport device according to the present invention. As shown in FIG. 1, the vibration-type transfer device 1 is a vibration device including an electrostatic motor 10 that linearly reciprocates, and is arranged in parallel with the driving direction of the electrostatic motor 10. And a vibrating conveyance path 5 which is connected to form a conveyance path.
[0009]
As shown in FIG. 2A, the electrostatic motor 10 includes a flat stator 11 having three-phase strip electrodes 11a, 11b, and 11c arranged in parallel and periodically with each other. It consists of a planar vibrator 12 having three-phase strip electrodes 12a, 12b, 12c arranged parallel and periodically to each other inside. In this case, the three-phase strip electrodes 11a, 11b, and 11c of the stator 11 and the three-phase strip electrodes 12a, 12b, and 12c of the vibrator 12 are arranged to face each other. In addition, the stator 11 is fixed on the base B, while the above-described vibration conveyance path 5 is fixed on the upper surface of the vibrator 12.

The electrostatic motor 10 is manufactured using a printed circuit board technique or the like, and is thin as a whole, and preferably has a thickness of 1 mm or less. In particular, the stator 11 and the vibrator 12 constituting the electrostatic motor 10 are manufactured by using an FPC (Flexible Print Circuit) substrate technology, and each of the stator 11 and the vibrator 12 is formed into a flexible film shape, so that the overall structure is made thinner. Is possible. In addition, a liquid having a high insulating property can be interposed between the stator 11 and the vibrator 12 in order to reduce friction and maintain the insulating property, but it is usually unnecessary.
[0011]
As shown in FIG. 2B, the electrostatic motor 10 further has a connection circuit 13, which generates a three-phase voltage to connect the stator 11 via the connection circuit 13. An application device 14 for applying to the three-phase strip electrodes 11a, 11b, 11c and the three-phase strip electrodes 12a, 12b, 12c of the vibrator 12 is connected. The connection circuit 13 includes, among the three-phase strip electrodes 11 a, 11 b, and 11 c of the stator 11 and the three-phase strip electrodes 12 a, 12 b, and 12 c of the vibrator 12, an electrode of the stator 11 located at an arbitrarily determined reference position; In the present embodiment, a voltage of the same phase is applied by the application device 14 to the electrode 11b and the electrode of the vibrator 12 facing the electrode 11b, that is, the electrode 12b of the vibrator 12 located at the reference position. At the same time, the same phase voltage is applied to the electrode 11a of the stator 11 located on one side with respect to the reference position and the electrode 12c of the vibrator 12 located on the other side with respect to the reference position. The same phase voltage is applied to the electrode 11c of the stator 11 located on the other side and the electrode 12a of the vibrator 12 located on one side with respect to the reference position.
[0012]
2 (a) and 2 (b), when the electrostatic motor 10 is driven continuously and linearly, the application device 14 may be a three-phase AC power supply, but when the electrostatic motor 10 is driven back and forth as in the present invention. Controls the application device 14 as described below.
[0013]
That is, in the present invention, the application device 14 controls the electrostatic motor 10 to reciprocate, and vibrates the vibrating conveyance path 5 with the reciprocation to control the conveyed object P to be effectively conveyed. In order to convey the article P, it is necessary that the reciprocating drive control is asymmetric. Particularly, for effective conveyance of the article P, for example, as shown in FIGS. 3A and 3B. Thus, it is desirable that the control be such that the relationship between the time and the driving displacement of the vibrator 12 is substantially saw-toothed. The three-phase voltage of the application device 14 for controlling the driving displacement of the vibrator 12 in this manner is determined as follows.
[0014]
The inventor of the present application proposes that, based on the fact that a normal three-phase AC voltage is applied to the continuous linearly driven electrostatic motor 10, the drive displacement of the vibrator 12 and the phase of the applied voltage are roughly as follows. It was found that there was a relationship. This correspondence is shown below.
[0015]
(Equation 1)

By utilizing this relationship, when the driving direction of the electrostatic motor 10 is reversed as shown by the arrow in FIG. 4A, the phase of the applied voltage may be reversed. Even when the driving displacement x of the electrostatic motor 10 is a complicated function x = f (t) of the time t, the above relational expression holds. For example, the relationship between the driving displacement x and the time t is shown in FIG. 4), the three-phase voltage is controlled so as to have a phase change as shown in FIG.
[0016]
Next, the operation of the present embodiment having such a configuration will be described. The application device 14 applies a three-phase voltage controlled based on a preset reciprocating drive displacement x via the connection circuit 13 to the three-phase band electrodes 11a, 11b, 11c of the stator 11 and the three-phase band of the vibrator 12. It is applied to the electrodes 12a, 12b, 12c. The vibrator 12 performs x displacement with respect to the stator 11 according to the applied voltage. Therefore, the vibration conveyance path 5 fixed to the vibrator 12 reciprocates, that is, vibrates with the reciprocation of the vibrator 12. In this case, if the relationship between the time and the drive displacement is asymmetric in the reciprocation, when the transported object P is placed on the vibration transport path 5, the transported object P is transported by the vibration.
[0017]
As described above, according to the present embodiment, the vibrator 12 of the electrostatic motor 10 and the vibration transport path 5 are fixed to each other, so that the vibration direction of the vibration transport path 5 is changed to the direction of the vibration transport path 5 (plane direction). Therefore, the problem that the transported object P on the vibration transport path 5 jumps up and the transported object P is damaged can be avoided. Further, since the driving force of the electrostatic motor 10 is proportional to the area of the electrodes 11a, 11b, 11c, 12a, 12b, 12c, even the electrostatic motor 10 having a large driving force is small, thin and lightweight. The entire device is also small and lightweight.
[0018]
The present embodiment is particularly advantageous in conveying sheet-like objects such as paper, cards, and disks. As these transporting devices, as shown in FIG. 12, a transporting device for a card C using rollers 105, a normal motor 106 and a belt 107 is known. By transporting the device, the device can be significantly reduced in size and thickness. For example, when the vibration-type transport device 1 according to the present invention is used in a device such as a printer, a copier, a card reader, and a disk drive, each device can be significantly reduced in size and thickness as shown in FIGS. Further, the vibrating transfer device 1 according to the present invention has the same advantage in the transfer of powder and various kinds of transferred objects P.
[0019]
Incidentally, the transport of the transported object P depends on the interaction between the transported object P and the vibration transport path 5, specifically, the frictional force and the electrostatic attraction force due to the static electricity. Therefore, for example, by utilizing the difference in the coefficient of friction of the transported object P, the vibration type transport apparatus 1 according to the present invention can be used as a separation mechanism or a classification mechanism. In this case, the relationship between the time and the driving displacement of the vibrator 12 is controlled, for example, as shown in FIG.
[0020]
Next, another embodiment of the vibration type transport apparatus according to the present invention will be described with reference to FIG. As shown in FIG. 5, in the present embodiment, the only difference is that the electrodes (skewed strip electrodes) 12d, 12e, and 12f of the vibrator 12 of the electrostatic motor 10 are skewed in a V-shape. The other configuration is substantially the same as the embodiment shown in FIGS.
[0021]
In FIG. 5, the same parts as those of the embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof will be omitted.
[0022]
In the embodiment shown in FIG. 5, since the electrodes 12d, 12e, and 12f of the vibrator 12 are skewed, the correspondence between the driving displacement of the vibrator 12 and the phase of the applied voltage shown in [Equation 1] is reduced. Since it appears more accurately, the driving of the vibrator 12 can be more stably controlled. Accordingly, in addition to the effects of the embodiment shown in FIGS. 1 to 4, the controllability of the drive displacement of the electrostatic motor 10 is greatly improved (Transactions of the Institute of Electrical Engineers of Japan, Vol. 117, No. 3, 1997, pp. 373-378).

Each of the two-phase strip electrodes 22a and 22b is arranged to face a position shifted outward with respect to the corresponding one-phase strip electrode 21a of the stator 21. Further, the electrostatic motor 20 generates a connection circuit 23 and an application for generating a three-phase voltage and applying the three-phase voltage to the one-phase band electrode 21 a of the stator 21 and the two-phase band electrodes 22 a and 22 b of the vibrator 22 via the connection circuit 23.
