About aforementioned and other technology contents, characteristics and effect of the present invention, more than following cooperation reference is graphic, in the detailed description of an embodiment, can clearly appear.The direction term of being mentioned in following examples, for example " on ", D score, " preceding ", " back ", " left side ", " right side " etc., only be direction with reference to annexed drawings.Therefore, the direction term of use is to be used for explanation, but not is used for limiting the present invention.

Fig. 1 is the stereographic map of the projector of one embodiment of the invention.Fig. 2 is the stereographic map that the lid of Fig. 1 exposes opening.Fig. 3 is the stereographic map of the projector of Fig. 2 in another visual angle.Please refer to Fig. 1 to Fig. 3, the projector 100 of present embodiment comprises main casing 110 and light source 120.Main casing 110 has opening 112 and at least one chute 114 (illustrate is two), and chute 114 is positioned on opening 112 inwalls.Light source 120 is disposed in the main casing 110 and by opening 112 and exposes.

Fig. 4 is the lid of Fig. 1 and the stereographic map of sliding part.Please refer to Fig. 2 to Fig. 4, projector 100 more comprises at least one sliding part 130 (illustrate is two) and lid 140, and sliding part 130 is slidedly arranged on the chute 114.Lid 140 is connected in sliding part 130, and wherein sliding part 130 is suitable for sliding between the two ends of chute 114, and makes lid 140 cover opening 112 (as shown in Figure 1) or exposure opening 112 (like Fig. 2 and shown in Figure 3).Configuration mode when user's desire is changed or keeped in repair light source 120, can directly promote lid 140 and make lid 140 expose opening 112 by this, makes the replacing of light source 120 or maintenance comparatively convenient.The main casing 110 of present embodiment and lid 140 common formation one shells are in order to protection projector 100 inner members.

Please refer to Fig. 1 and Fig. 2, in detail, main casing 110 has adjacent end face 110a and side 110b, and opening 112 extends to side 110b from end face 110a.Lid 140 comprises continuous main part 142 and extension 144.When lid 140 covering opening 112 as shown in Figure 1, main part 142 covers the part that openings 112 are positioned at end face 110a, and extension 144 covers the part that openings 112 are positioned at side 110b.When lid 140 exposure openings 112 as shown in Figure 2 and sliding part 130 are positioned at one of chute 114 when terminal, main part 142 is parallel to side 110b, and extension 144 is positioned at a bottom 118 of main casing 110.By this, no matter lid 140 is covering opening 112 as shown in Figure 1 or exposure opening 112 as shown in Figure 2, lid 140 is all the state that fits in main casing 110, puts projector's 100 requisite spaces and can save.

Please refer to Fig. 4, the sliding part 130 of present embodiment for example is screw and comprises head 132 and axial region 134.Axial region 134 is connected in lid 140 and passes chute 114 (being illustrated in Fig. 2 and Fig. 3), and head 132 is connected in axial region 134 and is positioned at chute 114.Fig. 5 is the partial schematic sectional view of sliding part 130 with the chute 114 of Fig. 3.Please refer to Fig. 5, in the present embodiment, can the external diameter of head 132 be designed to width, let head 132 be suitable for being limited in the chute 114, come off from chute 114 so that sliding part 130 is unlikely greater than chute 114.

Please refer to Fig. 3 and Fig. 4, the bottom surface of present embodiment lid 140 has at least one first fixture 140a (illustrating to a plurality of), and main casing 110 has at least one second fixture 116 (illustrating to a plurality of) in opening 112 edges.When lid 140 covered openings 112, the first fixture 140a and second fixture 116 were suitable for producing constructive interference with the fixing position of lid 140, avoid lid 140 to rock because of projector 100 and produce unexpected displacement.In addition, please refer to Fig. 1, the shell 100 of present embodiment more comprises at least one locking part 150 (illustrate is two), when lid 140 covers opening 112, can lid 140 be locked in main casing 110 by locking part 150, with the further fixedly position of lid 140.

Please refer to Fig. 3, in the present embodiment, the terminal 114a of chute 114 extends along the direction away from end face 110a.By this, when sliding part 130 when chute 114 slides into terminal 114a, lid 140 can be driven to be dropped to end face 110a copline and covers opening 112.In other words, before the terminal 114a of sliding part 130 no shows, can have spacing between lid 140 and the main casing 110, hindered when letting the user promote lid 140 to avoid lid 140 to contact with main casing 110.

In sum, in the above embodiment of the present invention, lid is suitable for relative main casing slip and covers or the exposure opening.When user's desire is changed or is keeped in repair light source, can directly promote lid and make lid expose opening, make the replacing of light source or maintenance comparatively convenient.In addition, all keep fitting in the state of main casing in the time of can lid being designed to cover opening or exposing opening, put projector's requisite space with saving.

The above; Be merely the present invention's preferred embodiment; When the scope that can not limit the present invention's enforcement with this, promptly change and modification according to claim of the present invention and the simple equivalent done of invention description generally, all still belong in the scope that patent of the present invention contains.In addition, arbitrary embodiment of the present invention or claim must not reached whole purposes or advantage or the characteristics that the present invention discloses.
