Imaging apparatus having print engine that includes MEMS device
View Patent ↗An imaging apparatus includes a controller executing instructions to form a latent image, and a print engine. The print engine includes a laser source, a micro-electromechanical system (MEMS) device, and a module for mounting the MEMS device. The print engine is communicatively coupled to the controller and configured to form the latent image using the laser source and the MEMS device. The module includes a base having a first support and a second support, the second support having a support guide feature; and a bracket attached to the MEMS device. The bracket has a central axis, a first end, and a second end, the second end having a bracket guide feature, the first end being affixed to the first support to form a cantilever arrangement. The support guide feature engages the bracket guide feature to form a sliding joint having a sliding axis substantially parallel to the central axis.
1. A controller executing instructions to form a latent image; a print engine including a laser source, a micro-electromechanical system (MEMS) device, and a module for mounting said MEMS device, said print engine communicatively coupled to said controller and configured to form said latent image using said laser source and said MEMS device in response to said instructions, and said module including: a base having a first support and a second support, said second support having a support guide feature; and a bracket attached to said MEMS device, said bracket having a central axis, a first end, and a second end, said second end having a bracket guide feature, said first end being affixed to said first support of said base to form a cantilever arrangement, said support guide feature engaging said bracket guide feature to form a sliding joint having a sliding axis substantially parallel to said central axis, wherein said sliding joint is configured to restrain said second end of said bracket in a first direction substantially perpendicular to said central axis of said bracket while allowing freedom of movement of said second end of said bracket in a second direction perpendicular to said central axis, said second end of said bracket being spaced apart from said second support of said base in said second direction to thereby cantilever said bracket in said second direction.
2. The imaging apparatus of claim 1 , further comprising a damper interposed between said bracket and said base.
3. The imaging apparatus of claim 2 , wherein said damper is interposed between said second end of said bracket and said second support of said base.
4. The imaging apparatus of claim 2 , wherein said damper damps a vibration of said bracket in said second direction.
5. The imaging apparatus of claim 2 , wherein said damper is an energy absorbing rubber.
6. The imaging apparatus of claim 2 , further comprising a datum pad interposed between said first end of said bracket and said first support of said base, said datum pad positioning said bracket relative to said base in said second direction.
7. The imaging apparatus of claim 6 , further comprising a pin joint coupling said first end of said bracket to said first support of said base, said pin joint positioning said first end of said bracket relative to said base in said first direction and in a third direction orthogonal to said first direction and said second direction.
8. The imaging apparatus of claim 7 , wherein said first direction is a Y-axis direction, said second direction is a Z-axis direction, and said third direction is an X-axis direction, each of said Y-axis direction, said Z-axis direction, and said X-axis direction being mutually orthogonal.
9. The imaging apparatus of claim 7 , wherein said first support of said base includes a pin protruding therefrom, and wherein said first end of said bracket includes a socket receiving said pin, thereby forming said pin joint.
10. The imaging apparatus of claim 7 , wherein said first end of said bracket includes a pin protruding therefrom, and wherein said first support of said base includes a socket receiving said pin, thereby forming said pin joint.
11. The imaging apparatus of claim 7 , wherein said support guide feature is a lug extending from second support of said base, and said bracket guide feature is a slot receiving said lug, thereby forming said sliding joint.
12. The imaging apparatus of claim 11 , wherein said lug is a pin.
13. The imaging apparatus of claim 7 , wherein said bracket guide feature is a lug extending from said second end of said bracket, and said support guide feature is a slot receiving said lug, thereby forming said sliding joint.
14. The imaging apparatus of claim 13 , wherein said lug is a pin.
15. The imaging apparatus of claim 6 , further comprising a fastener passing through said datum pad and securing said first end of said bracket to said first support of said base.
16. The imaging apparatus of claim 1 , wherein said MEMS device is a torsion oscillator.
