Abstract
Disclosed is a driving device, and more particularly, to a lens driving device for transporting a lens of an optical instrument via separate actuation of the lens itself. In the driving device, guide means are connected perpendicularly with the lens for guiding reciprocating movement of the lens. Driving means is arranged coplanar with the lens and fixed by a first end to a periphery of the lens for providing the lens with a transport force which is larger than an interactive force between the lens and the guide means.
Claims60
A driving device for transporting an object, comprising:
- guide means connected with the object for guiding the object;
- and
- driving means attached to the object for providing the object a driving force which is larger than an interactive force between the object and the guide means.
A driving device for transporting a lens of an optical instrument, comprising:
- guide means connected perpendicularly with the lens for guiding reciprocating movement of the lens;
- and
- driving means arranged coplanar with the lens and fixed by a first end to a periphery of the lens for providing the lens with a transport force which is larger than an interactive force between the lens and the guide means.
A driving device for transporting a lens in an optical instrument, comprising:
- guide means connected perpendicularly with the lens for guiding reciprocating movement of the lens;
- and
- driving means having a first end fixed perpendicularly to a face of the lens to provide the lens with a transport force which is larger than an interactive force between the lens and the guide means.
A driving device for transporting a lens of an optical instrument, comprising:
- guide means connected perpendicularly with the lens for guiding reciprocating movement of the lens;
- elastic means for enabling elastic contact between the lens and the guide means to provide the lens and the guide means with an interactive force proportional to an elastic force;
- piezoelectric driving means being coplanar with the lens, having a first end fixed to a periphery of the lens, and powered by a supply voltage to provide the lens with a transport force which is larger than an interactive force between the lens and the guide means;
- a weight of a predetermined mass attached to a second end of the piezoelectric driving means opposite to the first end.
A driving device for transporting a lens of an optical instrument, comprising:
- guide means extended through the lens in a position adjacent to the periphery of the lens for guiding reciprocating movement of the lens;
- elastic means for enabling elastic contact between the lens and the guide means to provide the lens and the guide means with an interactive force proportional to an elastic force;
- piezoelectric driving means having a first end fixed perpendicularly to a face of the lens, and powered by a supply voltage to provide the lens with a transport force which is larger than an interactive force between the lens and the guide means;
- and
- a weight of a predetermined mass attached to a second end of the piezoelectric driving means opposite to the first end.
A driving device for transporting a lens of an optical instrument, comprising:
- an external frame being in contact with a peripheral surface of the lens for guiding reciprocating movement of the lens;
- elastic means for enabling elastic contact between the lens and the external frame to provide the lens and the external frame with an interactive force proportional to an elastic force;
- piezoelectric driving means having a first end fixed perpendicularly to a face of the lens, and powered by a supply voltage to provide the lens with a transport force which is larger than an interactive force between the lens and the guide means;
- and
- a weight of a predetermined mass attached to a second end of the piezoelectric driving means opposite to the first end.
