Abstract
A turntable device principally includes a horizontal rotation base and an up-and-down swinging mechanism, which are driven by VCMs. An optical apparatus is placed on supports, which are arranged on the horizontal rotation base, with a horizontal rotation shaft therebetween. The optical apparatus is directed up-and-down and right-and-left by movable pieces connected to movable coils of the VCMs, so as to constitute the turntable device. The optical apparatus is placed on the turntable.
Claims29
A turntable device for changing a direction of an optical apparatus comprising:
- a base;
- a horizontally rotatable table being rotatable right-and-left and disposed on the base;
- supports disposed on the horizontally rotatable table;
- an up-and-down swinging shaft to be connected to the optical apparatus through the supports for supporting the up-and-down swinging shaft;
- horizontally rotating means arranged on the base for rotating the horizontally rotatable table right-and-left so as to rotate the optical apparatus right-and-left;
- and
- up-and-down swinging means arranged on the horizontally rotatable table for swinging the optical apparatus up-and-down about the up-and-down swinging shaft,
- wherein the optical apparatus can be directed up-and-down and right-and-left.
A camera-platform mechanism for changing a direction of an object to be mounted principally comprising:
- a base;
- a gimbal spring, on which the object to be mounted is placed with the base therebetween;
- a VCM having a movable coil;
- and
- an arm connected to the movable coil of the VCM,
- wherein the object to be mounted is directed by pushing a side surface of the object to be mounted with the arm.
A camera platform comprising:
- a rotatable table;
- a holder member slidably disposed on the table;
- a movable base journaled on the table rotatably in a direction different from that of the table;
- a first driving unit for rotating the table in the circumferential direction of the table;
- a second driving unit for sliding the holder member;
- and
- rotation converting means for converting the sliding movement of the holder member into the rotational movement of the movable base,
- wherein a rotation shaft of the movable base is arranged outside the second driving unit.
