Abstract

A rotating device includes a carrier, a rotating plate, and a driving unit. The rotating plate rotatably connected with a pivot portion of the carrier contains a test liquid. The rotating plate or the driving unit has a stopping portion. When the driving unit drives the rotating plate to rotate so the stopping portion moves to a first position and interferes with the carrier, the driving unit applies driving force to the pivot portion of the carrier along a first rotation direction through the rotating plate. When the carrier rotates along the first rotation direction and the driving unit applies driving force to the rotating plate along a second rotation direction opposite to the first rotation direction, the rotating plate rotates relative to the carrier, the stopping portion moves to a second position and interferes with the carrier, and the driving unit applies driving force to the pivot portion of the carrier along the second rotation direction through the rotating plate.

First claim

What is claimed is:

1. A rotating device, comprising:
a carrier, has at least one pivot portion;
at least one rotating plate rotatably connected with the at least one pivot portion, wherein a rotating center of the earner is different from a rotating center of the at least one rotating plate; and
a driving unit connected with the at least one rotating plate, wherein the at least one rotating plate or the driving unit comprises at least one stopping portion for interfering with the earner, the driving unit comprises a rotating member engaged with the at least one rotating plate, and a radius of the at least one rotating plate is larger than a radius of the rotating member, and
wherein the carrier comprises at least two stopping surfaces, when the at least one stopping portion is at a first position on the carrier, the at least one stopping portion is against one of the at least two stopping surfaces, and when the at least one stopping portion is at a second position on the carrier, the at least one stopping portion is against the other one of the at least two stopping surfaces,
wherein the rotating member rotates along a first rotation direction to cause the at least one stopping portion to move to the first position, and the rotating member rotates along a second rotation direction to cause the at least one stopping portion to move to the second position.

2. The rotating device according to claim 1 , wherein the rotating member comprises a first gear and the at least one rotating plate comprises a second gear, and the first gear is engaged with the second gear.

3. The rotating device according to claim 1 , wherein the driving unit comprises a linking rod with two ends pivotally connected with the rotating member and the at least one rotating plate respectively.

4. The rotating device according to claim 1 , wherein the driving unit comprises a transmission belt, and the transmission belt is connected between the rotating member and the at least one rotating plate.

5. The rotating device according to claim 1 , wherein the driving unit comprises a base, the base is connected with the rotating member.

6. The rotating device according to claim 1 , comprising at least one first magnetic member and at least one first attractable member, wherein the at least one first attractable member is attracted by a magnetic force generated by the at least one first magnetic member, the number of the at least one rotating plate is two, the at least one first magnetic member and the at least one first attractable member are disposed on the two rotating plates respectively, and when the at least one stopping portion is at the first position or the second position, the two rotating plates are positioned by the magnetic force between the at least one first magnetic member and the at least one first attractable member.

7. The rotating device according to claim 1 , comprising at least one first magnetic member and at least one first attractable member, wherein the at least one first attractable member is attracted by a magnetic force generated by the at least one first magnetic member, the at least one first magnetic member and the at least one first attractable member are disposed on the carrier and the at least one rotating plate respectively.

8. The rotating device according to claim 1 , comprising an elastic member, wherein the elastic member is connected between the earner and the at least one rotating plate, and when the at least one stopping portion is at the first position or the second position, an elastic force of the elastic member positions the at least one rotating plate and when the at least one stopping portion is located between the first position and the second position, the elastic force of the elastic member causes the at least one rotating plate to rotate so that the at least one stopping portion moves toward the first position or the second position.

9. The rotating device according to claim 5 , wherein the base comprises a recess for accommodating the carrier.

10. The rotating device according to claim 5 , wherein the at least one stopping portion is located on the base.

11. The rotating device according to claim 9 , wherein the at least one stopping portion is located on a bottom of the recess.

12. The rotating device according to claim 5 , comprising at least one first magnetic member and at least one first attractable member, wherein the at least one first magnetic member and the at least one first attractable member are disposed on the carrier and the base respectively.
