Optical carriage of scanner and method of the same
View Patent ↗An optical carriage of scanner has a mirror assembly and a device assembly, the mirror assembly has a mirror mount, some mirror holder, and some supporters, and the device assembly has a chassis. In this invention, the mirror assembly and the device assembly are mechanically connected after separately formation. Further, to ensure correct shape of these mirror holders and these supporters, they could be formed by metal punch, plastic ejection, or plastic process.
1. A mirror carriage, comprising:
at least one set of supporters contacting a mirror at three or more points; and
at least one mirror holder comprising at least a first and a second terminal, wherein the first terminal contacts a first surface of the mirror and the second terminal contacts a second surface of the mirror, and wherein the mirror holder is configured to cooperate with the at least one set of supporters to fix the mirror in place.
2. The mirror carriage of claim 1 , further comprising three groups, wherein each group includes two sets of supporters and two sets of mirror holders.
3. The mirror carriage of claim 2 , further comprising three mirrors arranged in an associated group of two sets of supporters and two sets of mirror holders.
4. The mirror carriage of claim 3 , wherein the three mirrors are arranged in an associated group of two sets of supporters and two sets of mirror holders to form an optical path between the three mirrors.
5. The mirror carriage of claim 1 , wherein the width of a gap between the supporter and the mirror holder is substantially equal to the thickness of the mirror.
6. The mirror carriage of claim 1 , wherein the mirror holders comprise elastic material.
7. The mirror carriage of claim 1 , wherein the at least one set of supporters contact at least a third surface and a fourth surface of the mirror.
8. A scanner, comprising:
a chassis; and
an optical assembly positioned in the chassis, wherein the optical assembly includes:
at least one supporter configured to contact a mirror at three or more points; and
at least one mirror holder comprising at least a first and a second terminal, wherein the first terminal is configured to contact a first surface of a mirror and the second terminal is configured to contact a second surface of the mirror, and wherein the mirror holder and the supporter are configured to fix the mirror to the optical assembly.
9. The scanner of claim 8 , wherein the at least one supporter and at least one mirror holder comprise a mirror assembly.
10. The scanner of claim 8 , further comprising three groups, wherein each group includes two sets of supporters and two sets of mirror holders.
11. The scanner of claim 10 , further comprising three mirrors arranged on the mirror assembly, wherein one or more of the three mirrors is arranged in an associated group of two sets of supporters and two sets of mirror holders.
12. The scanner of claim 11 , wherein the three mirrors are arranged on the mirror assembly to form an optical path between the three mirrors.
13. The scanner of claim 8 , further comprising an electronic element positioned in the chassis.
14. The scanner of claim 8 , wherein the width of a gap between the mirror holder and the mirror mount is substantially equal to the thickness of a mirror supported by the mirror holder.
15. The scanner of claim 8 , wherein the mirror holders comprise elastic material.
16. The scanner of claim 8 , wherein the at least one set of supporters contact at least a third surface and a fourth surface of the mirror.
17. An apparatus, comprising:
means for contacting a mirror at three or more points; and
means for supporting the mirror with at least a first and a second terminal, wherein the first terminal is configured to contact a first surface of the mirror and the second terminal is configured to contact a second surface of the mirror, and wherein the means for contacting and the means for supporting are configured to fix the mirror in place.
18. The apparatus of claim 17 , further comprising
means for positioning at least one mirror on the at least one mirror holder.
19. The apparatus of claim 17 , further comprising
means for forming three groups, wherein each group includes two sets of supporters and two sets of mirror holders.
20. The apparatus of claim 17 , further comprising
means for positioning the optical assembly in a scanner chassis.
21. The apparatus of claim 17 , further comprising
means for positioning an electronic element in the scanner chassis.
22. The apparatus of claim 17 , wherein the at least one set of supporters contact at least a third surface and a fourth surface of the mirror.
