Abstract
A portable real object display instrument, comprising a dc switching power supply, a color CCD camera, a metallic hose and a suitcase. The switching power supply is arranged in the suitcase box whose cover is provided with a hose interface, a video output port, a power supply indicator light and a power switch thereon. One end of the metallic hose is connected with the hose interface of the box cover, the other end is provided with a camera. The utility model has the advantages of low production cost, simple and flexible operation, convenient carrying, the 'universal property' of the lens can completely satisfy the needs of teacher videography from any angle. The utility model is mainly used in teaching, can conveniently and flexibly show words, pictures and experimental process on the screen of the TV and the projector in the form of videography.
Description
Technical field
The utility model relates to a kind of teaching presentation device, a kind of specifically portable demonstration instrument.
Technical background
Requirement along with development of electronic technology and Modern Education Technology, various material object display typhoons gush birth, but long-pending big, the complex structure of existing material object display stage body, the production cost height, cost an arm and a leg, and be awkward, the low-light level difference in response, can not " universal " as head, carry and install equal inconvenience.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of cheap, excellent performance, portable demonstration instrument easy to carry.
The technical scheme that the technical problems to be solved in the utility model adopts is:, a kind of portable material object display instrument, form by dc switching power supply, colored CCD camera, metal hose and suitcase, switching power supply is contained in the suitcase casing, and the casing capping is provided with hose connection, video output, power light and power switch; Metal hose one end is connected with hose connection on the casing capping, and the other end then is equipped with camera.
On the portable casing capping of demonstration instrument LCDs, liquid crystal display brightness regulating switch and liquid crystal display switch are housed also; The decoding deck that matches with LCDs then is housed in the casing.
Principle of work of the present utility model is: the alternating current of 100-240V passes through switching power supply, 12V is provided D.C. regulated power supply for the colored CCD camera, the light of subject reflection enters camera and light signal is changed into electric signal (being vision signal) here by equipment such as televisor, projector, computing machines scenery is reproduced then.
The utility model production cost is low, and is simple to operate, flexible.Easy to carry, " universal property " of camera lens can satisfy the demand of teacher from arbitrarily angled shooting fully.The utility model mainly is to be used for teaching, and it can be illustrated in literal, picture and the experimentation form by shooting on the screen of televisor and projection easily and flexibly.
