Abstract
The utility model discloses a multi-function image production instrument, comprising a video circuit, an audio circuit, a lighting circuit, and a power circuit. The utility model is characterized in that the multi-function image production instrument is also provided with a machine base, a foldable machine frame installed on the machine base, a lift mechanism which is installed on the machine frame and is provided with a camera, and an illumination lamp installed on the machine frame. A panel of the machine base is a rear projection screen, and the machine base is provided with a selective switch, an input and output interface for audio and vide. The utility model has the advantages of convenient portability and convenient use, and the utility model with multiple uses can be used for teaching, lecture, and business.
Description
The utility model relates to a kind of projection display equipment, is a kind of multi-functional video display instrument specifically.
Existing slide projector, the reflection type projection instrument can only carry out imaging to slide, function singleness, and be subjected to the external environment influence of light very big, and can only be used for darker occasion, image quality is also relatively poor.
The purpose of this utility model is to provide a kind of being easy to carry, multi-purpose video display instrument such as easy to use, teaching, lecture, commercial affairs.
To achieve these goals, the utility model adopts following technical scheme: a kind of multi-functional video display instrument, comprise video circuit, voicefrequency circuit, lighting circuit and power circuit, it is characterized in that: it also has a support, and is installed in the frame, that can amount on this support and is installed in the elevating mechanism and that video camera is housed on this frame and is installed in illuminating lamp on this frame, this support panel is a rear projection screen, and is provided with selector switch and audio frequency, video input, output interface on this support.
Good effect of the present utility model is: use any shading measure that do not need daytime in the classroom; Figure, manuscript can all show, but also local display is easy to adjust, give top priority to what is the most important, and effect is remarkable; Photographic negative can directly be turned into image, the convenient saving; Display image in kind is true to nature, has the effect of advertisement.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the structural representation of a preferred embodiment of the utility model;
Fig. 2 is a schematic diagram after the amounting to of a preferred embodiment of the utility model;
Fig. 3 is the video circuit schematic diagram of a preferred embodiment of the utility model.
Seeing also Fig. 1, Fig. 2 and shown in Figure 3, is preferred embodiment of the utility model.The utility model is installed in the frame 2, that can amount on this support by a support 1, and is installed in the illuminating lamp 5 that the elevating mechanism 4 and that video camera 3 is housed on this frame is installed on this frame and forms.The support panel is a rear projection screen 6, and on this support, be provided with functional select switch 7 and video, audio frequency input/output interface 8, be provided with video circuit 9, voicefrequency circuit (not shown), lighting circuit (not shown), power circuit (not shown) in this support.Above-mentioned elevating mechanism is mainly used to regulate image pickup scope, and lifting knob 10 on the frame and fixed knob 11 realize by being located at.The above-mentioned functional select switch control erect image illumination and the exchange function of back lighting and positive negative-appearing image.The utility model adopts the high frequency fluorescent lamp lighting to reduce the interference to television image.The utility model video circuit working condition is achieved in that camera system CCD obtains signal of video signal, and behind this signal of video signal input video control circuit 9, the inverting circuit 91 of leading up to obtains energizing signal and delivers to signal switching circuit 92 with original signal; Another road obtains synchronizing signal through synchronizing separator circuit LM1881 and is added on signal of video signal and the commutation circuit through clamp circuit 93, after selection circuit 7 control backs from output interface 8 outputting video signals, supply the television set display image.This video circuit operating voltage is direct current 9V.
Frame of the present utility model can be rotated around axle 12, as shown in Figure 2, is convenient for carrying after closing.Support one side is provided with a handle 13.
