As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 5, a kind of multipurpose projection device that an embodiment of the present invention provides,
It is characterized by comprising projection arrangement 1, reflection unit 2, viewing area 3, touch device 4 and pedestals 5.The projection arrangement 1 and institute
It states touch device 4 to be all mounted on the pedestal 5, the projection arrangement 1 is in the side of the viewing area 3, the touch device 4
In the top of the viewing area 3, the touch device 4 is induction camera, and the induction camera is located at the projection arrangement 1
Top.The reflection unit 2 is located at the top of the pedestal 5, and the reflection unit 2 is from the top of the pedestal 5 to institute
The direction for stating viewing area 3 extends, and the camera lens of the projection arrangement 1 is towards the reflection unit 2.The reflection unit 2, which is located at, to be thrown
Between shadow instrument and the viewing area 3.The bottom of the reflection unit 2 is equipped with plane mirror, the mirror surface of the plane mirror and the base
The bottom surface of seat 5 is parallel, and the light that projector projects is fallen on the viewing area 3 by plane mirror reflection.
As shown in figs. 1-4, the bottom surface Yu the back side of the pedestal 5 are placed side, and the corner at 5 back side of pedestal is equipped with height
Spend adjusting knob 51.There are two types of projection modes for the multipurpose projection device tool of the utility model, the first is desktop projection mode,
Another kind is wall projection mode.When user needs using desktop projection mode, the bottom surface of the pedestal 5 is put towards desktop
It sets, the mirror surface of plane mirror towards desktop, throw on the table by the picture for projecting whole equipment；When user needs to project using wall
When mode, the back side of the pedestal 5 is placed towards desktop, so that the height adjustment knob 51 is in contact with desktop, then pass through rotation
Turn the gradient that the height adjustment knob 51 adjusts the back side of the pedestal 5, the picture for projecting whole equipment is thrown suitable
Place.Since the height adjustment knob 51 belongs to very common mechanical structure, therefore the utility model does not construct progress to it
It repeats.The light that the projection arrangement 1 issues is reflected on perspective plane by this multipurpose projection device by the reflection unit 2,
Ensure that the image projected will not be deformed, not only can be used as common projector and thrown picture on wall, but also can be by picture
Throw on the table so that user can not only watch the content of courses at a distance by multipurpose projection device, but also can closely with
The image interactive of projection improves user's learning efficiency.
As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 5, it is equipped with PC machine and controller in the pedestal 5, the controller is
