As shown in Figure 2, an end 118a of butting section 118 has inclined-plane 120.The perforation 130 of housing 102 and outstanding towards second direction D21 from support component 114 is located at slidably along second direction D21 in butting section 118, make the inclined-plane 120 of butting section 118 be resisted against the end 110 of first fine adjustment screw 104, the other end 118b of butting section 118 is then on light pipe 112.Wherein, second direction D21 is in fact perpendicular to first direction D11.
When the rotation of first fine adjustment screw 104 and when first direction D11 moves, the end 110 of first fine adjustment screw 104 promotes the inclined-plane 120 of the butting section 118 of guiding devices 106, makes light pipe 112 move to the tram toward the opposite direction D22 of second direction D21.Thus, the light of deriving from light pipe 112 can project the picture that is possessed of good qualities.
Please refer to Fig. 3, it illustrates the synoptic diagram of the support component of Fig. 2.Support component 114 is a rubber-like bending plate, therefore has adjustable.Support component 114 comprises the first supporting body 114d1, the second supporting body 114d2, the first elastic 114a and the second elastic 114b and has perforate 114c.Support component 114 hang in the hook portion 142 (hook portion 142 is illustrated in Fig. 2) of housing 102 with perforate 114c.The first supporting body 114d1 be connected with the second supporting body 114d2 and the first supporting body 114d1 and the second supporting body 114d2 between angle about 90 the degree.
Folder one acute angle A1 and be resisted against the bottom surface 132 of light pipe 112 between the first elastic 114a and the first supporting body 114d1 is to provide strength toward the opposite direction D12 of first direction D11 to light pipe 112.Say further, please be simultaneously with reference to Fig. 2, when the opposite direction D12 of 116 rotations of second fine adjustment screw and past first direction D11 moved, the first elastic 114a applied elastic force in light pipe 112, made light pipe 112 past D12 in the other direction move to the tram; And when second fine adjustment screw 116 did not rotate and stops at a position, the first elastic 114a and second fine adjustment screw 116 movably seized light pipe 112 in the rest position along first direction D11 on both sides by the arms.
Similarly, among Fig. 3, folder one acute angle A2 and be resisted against the side 134 (side 134 is illustrated in Fig. 2) of light pipe 112 between the second elastic 114b and the second supporting body 114d2 is to provide strength toward second direction D21 to light pipe 112.Say further, please be simultaneously with reference to Fig. 2, when the opposite direction D12 of 104 rotations of first fine adjustment screw and past first direction D11 moves, the second elastic 114b applies elastic force and gives light pipe 112, make light pipe 112 promote butting sections 118 and move, light pipe 112 thereby be movable to the tram toward second direction D21; When first fine adjustment screw 104 did not rotate and stops at a position, the second elastic 114b and first fine adjustment screw 104 movably seized light pipe 112 in the rest position along second direction D21 on both sides by the arms.
In addition, in an embodiment, please refer to Fig. 4, it illustrates the synoptic diagram according to the support component of the ray machine module of another embodiment of the present invention.Support component 214 is the bending framework, and it surrounds three lateral surfaces of light pipe 112 and has perforate 244.Wherein, the other end 118b of butting section 118 can pass perforate 244 on light pipe 112.Because support component 214 is a framework,, avoid light pipe 112 element on every side the position of light pipe 112 to be offset because of touching light pipe 112 so can surround most lateral surface in the light pipe 112.
Please refer to Fig. 5 and Fig. 6, Fig. 5 illustrates the partial perspective view according to the ray machine module of second embodiment of the invention, and Fig. 6 illustrates the side view of the ray machine module that past direction V2 watches among Fig. 5.Continue to use same numeral with the first embodiment something in common among second embodiment, do not repeat them here.Ray machine module 100 differences of the ray machine module 300 of second embodiment and first embodiment are, first fine adjustment screw 304 of ray machine module 300 sees through impeller 346 and promotes butting section 318, makes butting section 318 promote light pipe 112 to change the position of light pipe 112.
In detail, ray machine module 300 comprises housing 302, first fine adjustment screw 304, second fine adjustment screw 116, impeller 346, guiding device 306 and flexible member 354.Impeller 346 is located in the chute 352 of housing 302 slidably and is resisted against first fine adjustment screw 304.Guiding device 306 comprises light pipe 112, support component 114 and butting section 318.Butting section 318 is located at the perforation 130 of housing 302 slidably and is resisted against impeller 346 towards second direction D21.Preferable but non-exclusively, impeller 346 has projection 346a, butting section 318 is resisted against on the projection 346a of impeller 346.
At least one has the inclined-plane in butting section 318 and the impeller 346, and it is that example explains that present embodiment has inclined-plane 320 with butting section 318.When the rotation of first fine adjustment screw 304 and when first direction D11 moves, first fine adjustment screw 304 drives impeller 346 and moves toward first direction D11, so that impeller 346 promotes butting section 318, butting section 318 and then promotion light pipe 112 move to the tram toward the opposite direction D22 of second direction D21.
Flexible member 354 for example is spring (spring), and it connects housing 302 and impeller 346.Flexible member 354 imposes strength and gives impeller 346, makes impeller 346 be resisted against first fine adjustment screw 304.That is, impeller 346 is movably seized on both sides by the arms between first fine adjustment screw 304 and flexible member 354.
In addition, in an embodiment, please refer to Fig. 7, it illustrates first fine adjustment screw of another embodiment of the present invention and the synoptic diagram of impeller.First fine adjustment screw 404 is formed in one with impeller 446.One end 418a of butting section 418 can have inclined-plane, cambered surface or plane, and the butting section 418 of this another embodiment is to be the example explanation to have cambered surface.Impeller 446 has inclined-plane 420, and it is the taper surface.When moving when 404 rotations of first fine adjustment screw and toward first direction D11, the inclined-plane 420 of impeller 446 promotes butting section 418 toward the opposite direction D22 of second direction D21, and the opposite direction D22 that makes butting section 418 promote light pipe 112 past second direction D21 moves to the tram.
The disclosed ray machine module of the above embodiment of the present invention, second fine adjustment screw and first fine adjustment screw be all along the first direction setting, thereby can vacate the space that is positioned at the second direction of guiding device in the ray machine module, to increase projection arrangement volume inside design flexibility.In addition, first fine adjustment screw is arranged in identical side of ray machine module and configuration located adjacent one another with second fine adjustment screw, thus, can once finish operation in the same side of ray machine module to first fine adjustment screw and second fine adjustment screw, do not need the map function direction, can quicken to adjust the speed of light pipe position and save many adjustment times.
The present invention is described by above-mentioned related embodiment, yet the foregoing description is only for implementing example of the present invention.Must be pointed out that the embodiment that has disclosed does not limit the scope of the invention.
