It is further preferred that the size and shape in the face of the transparent cabinet vertical with connecting rod and a face of dice are mutual
Matching.The purpose of the preferred embodiment is so that the face of transparent cabinet always downward is just matched with dice under stationary state,
When transparent cabinet is static in this way, the position of dice is always fixed.The advantages of being arranged in this way is that miniature webcam alignment is facilitated to clap
It the position taken the photograph and quickly brings to focus, avoids dice from falling and cannot be introduced into the coverage of miniature webcam in excessively inclined place.
Preferably, the shape of transparent cabinet is positive polygon prism shape.When positive polygon prism is rotated along axis, bottom surface switching frequency is more
It is high so that the rolling of dice is more abundant.
Preferably, the side of miniature webcam is provided with light compensating lamp.Light compensating lamp is for irradiating transparent cabinet so that miniature to take the photograph
As the shooting of head is more clear.
Preferably, terminal box side is provided with the data connector for connecting computer, and data connector passes through data line and throwing
Shadow instrument component connects.It is excessively single in order to avoid the function of equipment, thus be arranged data connector enable projecting apparatus component with
Computer connects, and realizes the function of general projectors.Accordingly even when without probability teaching demonstration, other content can be also carried out
Projection.
Preferably, it demonstrates work department and projecting apparatus component is located at the top of terminal box, circuit is provided in the terminal box
Integral part, circuit integral part are located at the underface of projecting apparatus component.Circuit integral part is used for integrated installation miniature webcam and throwing
The electric elements of shadow instrument component.The advantages of preferred embodiment is compact to design, is conducive to the miniaturization of equipment.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1. the image magnification of the random effect of dice in transparent cabinet is projected, it is thus achieved that easily more in number
Classroom on demonstrated.
2. rotating transparent cabinet by shake handle can be realized demonstration, easy to operate.
3. handle heavier-weight, in this way after stopping shaking rocking bar, handle is naturally drooped due to the effect of gravity, to
Ensure stationary state under, transparent cabinet always with the same face downward.
4. so that the face of transparent cabinet always downward is just matched with dice under stationary state, such transparent cabinet is quiet
When only, the position of dice is always fixed.Facilitate the position of miniature webcam alignment shooting and quickly bring to focus, avoids dice
It falls and cannot be introduced into the coverage of miniature webcam in excessively inclined place.
5. positive polygon prism is rotated along axis, bottom surface switching frequency higher so that the rolling of dice is more abundant.
6. light compensating lamp is for irradiating transparent cabinet so that the shooting of miniature webcam is more clear.
7. the function in order to avoid equipment is excessively single, therefore data connector is set and enables projecting apparatus component and computer
Connection, realizes the function of general projectors.Accordingly even when without probability teaching demonstration, the throwing of other content can be also carried out
Shadow.
8. each part design is compact, be conducive to the miniaturization of equipment.
