Embodiment
Fig. 3,4 are referred to, projection arrangement 100 of the invention includes housing 20.Ray machine (not shown) is arranged in housing 20,
Camera lens 30 is connected to ray machine and is arranged at a side 22 of housing 20.Light projection direction adjusting mechanism 40 is arranged at the side of housing 20
Side 22, light projection direction adjusting mechanism 40 includes lens cap body 42, face mirror 44 and protecgulum 46.Lens cap body 42 is slidably
Ground is arranged at the side 22 of housing 20 and is hollow cuboid, covers camera lens 30, and will by partition wall 421 (referring to Fig. 5)
Inside is divided into the first space 422 and second space 424, corresponds to the first space 422 in the antetheca 425 of lens cap body 42
Position forms opening 426, and protecgulum 46 is slidably disposed in antetheca 425, and can cover opening 426.Face mirror 44 is then arranged at
In two spaces 424, the normal of face mirror 44 is about in 45 degree of angle with the optical axis of camera lens 30.
Fig. 4,5 are referred to, as it was previously stated, lens cap body 42 is slidingly disposed at the side 22 of housing 20 and can be in first
Slided between position and the second place.When lens cap body 42 slides into first position, as shown in figure 4, camera lens 30 is aligned
First space 422, when protecgulum 46 slides and exposes opening 426, light directs out throwing via camera lens 30 through opening 426
Penetrate, for example, project to a screen.When lens cap body 42 slides into the second place, as shown in figure 5, the alignment of camera lens 30 second is empty
Between 424, light is irradiated via camera lens 30, and is reflected by face mirror 44 and be about in 90 degree of direction towards the optical axis with camera lens 30
Projection, therefore compared with the projecting direction of light in Fig. 4, the projecting direction of light changes 90 degree in Fig. 5.In actual application
On, it can be projected to by script towards the light of the front of projection arrangement 100 projection on ceiling or desktop.
Fig. 6 A, 6B represent another embodiment of the projection arrangement of the present invention.In the present embodiment, the structure of lens cap body 42
Make identical with the embodiment of Fig. 3~5.But the lens cap body 42 of the present embodiment is rotationally arranged at housing 20 by pivot 48
Side 22 and the 3rd position and the 4th position can be positioned at.When lens cap body 42 is rotated to three positions, such as Fig. 6 A
Shown, camera lens 30 is directed at the first space 422, and when protecgulum 46 slides and exposes opening 426, light passes through opening via camera lens 30
426 direct out projection, for example, project to screen.When lens cap body 42 is rotated to four positions, as shown in Figure 6B, camera lens
30 alignment second spaces 424, light irradiates via camera lens 30, and by face mirror 44 reflect and towards the optical axis with camera lens 30 about
Projected in 90 degree of directions, therefore compared with the projecting direction of light in Fig. 6 A, the projecting direction of light changes 90 in Fig. 6 B
Degree.
Fig. 7 A, 7B represent another embodiment of the projection arrangement of the present invention.The construction of the lens cap body 42 of the present embodiment
It is different from the various embodiments described above.The lens cap body 42 of the present embodiment is hollow cuboid, is fixed on the side 22 of housing 20,
The first opening 428 and second is respectively equipped with the corresponding position of camera lens 30 on the antetheca 425 and side wall 427 of lens cap body 42
Opening 429.Face mirror 44 is arranged in lens cap body 42, and the optical axis of its normal and camera lens 30 is about in 45 degree of angle, face mirror
44 are movably arranged in lens cap body 42, and can be moved between the 5th position and the 6th position.Mirror 44 exists face to face
During five positions, as shown in Figure 7 A, camera lens 30 be aligned opening 428, light via camera lens 30 through first opening 428 directly to
Outer projection, for example, project to screen.When mirror 44 is moved to six positions face to face, i.e., when face mirror 44 is moved to the front of camera lens 30,
As shown in Figure 7 B, light is irradiated via camera lens 30, and by face mirror 44 reflect and towards the optical axis with camera lens 30 about be in 90 degree
Direction through the second outwards projection of opening 429, therefore compared with the projecting direction of light in Fig. 7 A, the projection of light in Fig. 7 B
Direction changes 90 degree.In order to avoid leakage of light, first can be set at the first opening 428 and the second opening 429 respectively
Protecgulum and the second protecgulum, but in order to clearly show that the position of face mirror 44, eliminated in Fig. 7 A, 7B before the first protecgulum and second
Lid.And the mechanism for moving face mirror 44 is the push rod for being connected to face mirror 44, in a manual fashion moves face mirror 44, have no
It is special to limit.
Fig. 8 represents another embodiment of the projection arrangement of the present invention.In the present embodiment, lens cap body 42 is removably
The side 22 of housing 20 is installed on, face mirror 44 is installed on lens cap body 42.When not installing lens cap body 42, light warp
Projection is directed out by camera lens 30, for example, projected to screen.When lens cap body 42 is installed on before camera lens 30, light is via mirror
First 30 irradiate, and are reflected by face mirror 44 and about projected towards the optical axis with camera lens 30 in 90 degree of direction.
Compared with prior art, face mirror 44, which is used only, in projection arrangement 100 of the invention can change the projecting direction of light,
Carrying the housing of ray machine and camera lens can keep complete, it is not necessary to be divided into two parts, can so avoid the structure of complexity, increase
The reliability and reduction manufacturing cost of adding system.
