Abstract
The disclosure provides a moving apparatus for a projector. The projector includes a body, a processing unit and a projection lens. The moving apparatus includes a base having a through-base opening. At least one moving stage movably disposed on a front side surface of the base along a plane and has at least one through-stage opening aligned with the through-base opening. At least one magnetic component disposed on a carrier board, wherein a projection position of the projection lens is positioned by the at least one magnetic board through magnetic attraction. The at least one magnetic component is electrically connected to the processing unit.
Claims19
A moving apparatus, disposed in a projector, wherein the projector comprises a body, a processing unit and a projection lens, and the moving apparatus comprising:
- a base, having a through-base opening;
- at least one moving stage, movably disposed on the base, and having at least one through-stage opening aligned with the through-base opening;
- a carrier board;
- and
- at least one magnetic component, disposed on the carrier board, wherein a projection position of the projection lens is positioned by the at least one magnetic component through magnetic attraction, and the at least one magnetic component is electrically connected to the processing unit, wherein the carrier board has a through-carrier board opening, the through-carrier board opening is aligned with the through-base opening and the at least one through-stage opening, the carrier board is disposed on a rear side surface opposite to a front side surface of the base, and the at least one magnetic component is disposed through the base and abuts against the at least one moving stage, wherein the projection lens is connected to the at least one moving stage and passes through the at least one through-stage opening, the through-base opening and the through-carrier board in sequence and enters the body, the at least one moving stage is controlled by the processing unit.
An adjusting method of a moving apparatus, configured to adjust a projection lens of a projector, wherein the moving apparatus comprises a base, at least one moving stage, a carrier board and at least one magnetic component, wherein the projection lens is connected to the at least one moving stage, the at least one magnetic component is electrically connected to a processing unit of the projector and the at least one moving stage is controlled by the processing unit, the adjusting method comprising:
- driving the processing unit;
- demagnetizing the at least one magnetic component through the processing unit, the at least one magnetic component disposed on the carrier board;
- driving the at least one moving stage to generate movement through the processing unit;
- driving the projection lens to move through the at least one moving stage;
- disabling to drive of the processing unit;
- magnetizing the at least one magnetic component through the processing unit;
- and
- the at least one magnetic component generating magnetic force to position the projection lens, wherein the carrier board has a through-carrier board opening, the through-carrier board opening is aligned with the through-base opening and the at least one through-stage opening, the carrier board is disposed on a rear side surface opposite to a front side surface of the base, and the at least one magnetic component is disposed through the base and abuts against the at least one moving stage, wherein the projection lens is connected to the at least one moving stage and passes through the at least one through-stage opening, the through-base opening and the through-carrier board in sequence and enters a body, the at least one moving stage is controlled by the processing unit.
