Abstract
The invention discloses a portable video display bench for teaching. The bench comprises a base with a backlight plate. A control bench with a built-in rechargeable power supply is disposed on the base. A desk light neck which can be twisted and bent is fixed on the control bench. A machine head is fixed with the desk light neck through a support. A CCD lens is arranged on an end of the machine head. Light supplement lamps with desk light necks are arranged on two sides of the control bench. The bench uses the desk light necks to replace complex mechanical structures for stretching and retracting, so that the bench is simpler than other similar products in structure. Besides, the bench is provided with the built-in rechargeable power supply, so that no long connection line is needed during teaching, and thereby usage in teaching is greatly facilitated.
Description
Technical field
The invention belongs to teaching equipment technical field, particularly relate to a kind of video showing platform.
Background technology
Scanner in the market presses the difference of photo-electric conversion element, is generally CCDChargeCoupledDevice, photoelectricity coupling inductor scanner.Light signal on CCD, is converted to electric signal imaging by lens focus by it, and the latter is close to the scanning that contact is carried out on scanning contribution surface.Ccd scanner, by direct exposure in lens focus to CCD, can carry out material object scanning very easily.In scanner, sensor devices CCD is a kind of technology of comparative maturity, and its cost is lower, and image quality is but more and more higher, and some even can compare favourably with the photomultiplier that uses in rotating drum image scanner, has high cost performance.Adopt the requirement of CCD to ambient temperature of silicon single crystal technology lower, the scope of adaptation is wider.Along with the development of technology, commercially also there is a kind of video presenter at present, video presenter is also known as article showing platform, when it is connected on projector and televisor, just data, teaching materials, material object, lantern slide etc. clearly can be displayed, be one of indispensable teaching equipment of multi-media classroom.The video showing platform that one Daepori is logical comprises three parts: camera, light source and table top, also have a series of interface at the show stand back side, and some show stands towards high-end market also comprise the annexes such as infrared remote controller, computer picture capture adapter, LCD monitor.Video showing platform can be applied in each course teaching: literal arts class can various resources material, and the various books space of a whole page is used in teaching, and be directly placed in show stand table top, by the application of light, the adjustment of enlarging function, just can clearly show; Chemistry, physics subject directly can carry out some experiments on show stand, allow each student's clear view; Biological, medical science subject can observe enlarged image in kind by the adapted (microscope is first-class) of show stand camera lens.Support the use with output, input equipments such as multimedia projector, large screen back projection TV, general television set, LCD monitor, video recorder, VCD, DVD player, microphones, video showing platform has purposes widely in information technology teaching again.Teacher only just conveniently need can carry out document display by dragging with hand up and down about document.But existing video showing platform inconvenient operation, the horizontal strut part of drive head unit is easily sagging or upwarp, and structure is still comparatively complicated.
Summary of the invention
In view of the above-mentioned problems in the prior art, fundamental purpose of the present invention is to address the deficiencies of the prior art, and provides a kind of Portable video display stand for imparting knowledge to students, and its structure is simple, easy to use, and has better imaging effect.
The technical solution used in the present invention is as follows:
A kind of Portable video display stand for imparting knowledge to students, comprise the base with backlight, base is provided with the control desk being built-in with rechargable power supplies, and control desk is fixed with can the desk lamp neck of torsional bending, desk lamp neck is fixed with head by support, and the end of head is provided with CCD camera lens; The both sides of control desk are also provided with the light compensating lamp with desk lamp neck.
Further, control desk is provided with front panel, and front panel is provided with power button and at least one function key.
Further, under using state, the CCD camera lens of head end is towards backlight.
Further, the weight of base is greater than the weight sum of head and light compensating lamp.
Further, the bottommost of base is provided with for anti-skidding non-slipping block.
In sum, compared with prior art, the invention has the beneficial effects as follows:
Present invention employs desk lamp neck, instead of complicated physical construction with desk lamp neck and reach flexible object, make the present invention more simple compared to other like product structures; The employing of CCD camera lens, also makes the present invention be provided with better imaging effect; And the also built-in rechargable power supplies of the present invention, when imparting knowledge to students, just need not connect very long line, this is very easy to the use of teaching.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is the structural representation of inside of the present invention.
Embodiment
All features disclosed in this instructions, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
As shown in Figure 1: a kind of Portable video display stand for imparting knowledge to students of the present embodiment, comprise the base 1 with backlight 2, base 1 is provided with the control desk 3 being built-in with rechargable power supplies, control desk 3 is provided with front panel and rear panel, front panel is provided with power button 10 with at least one function key 11(for control operation, work as CCD camera lens 6), the both sides of front panel are also provided with USB interface 9; Rear panel is also provided with the power interface for charging; Control desk 3 is fixed with can the desk lamp neck 4 of torsional bending, and desk lamp neck 4 is fixed with head 5 by support 8, and under using state, the CCD camera lens 6 of head 5 end is parallel with backlight 2 towards backlight 2, CCD camera lens 6; The end of head 5 is provided with CCD camera lens 6; The both sides of control desk 3 are also provided with the light compensating lamp 7 with desk lamp neck 4, and what adopt in the present embodiment is LED light supplement lamp, and it has optical efficiency high-low voltage, volume is little, the life-span is long, fast response time, shock resistance strong, the characteristics such as energy-saving and environmental protection; Can more firmly place to make this device, in base 1, add counterweight iron block in the present embodiment, make the weight of base 1 be greater than the weight sum of head 5 and light compensating lamp 7, simultaneously, be provided with for anti-skidding non-slipping block at the bottommost of base 1 again, this non-slipping block adopts the rubber blanket with fold.
CCD camera lens 6: compared to CMOS camera lens, its imaging effect is better; CCD it use a kind of semiconductor material of ISO to make, light can be transformed into electric charge, digital signal is converted to by analog to digital converter chip, digital signal is preserved by the flash memory of camera internal or built-in hard disk card after overcompression, thus easily data can be transferred to computing machine, and by means of the process means of computing machine, revise image with imagination as required.CCD is made up of, usually in units of mega pixel many photosensitive units.When CCD surface be subject to light irradiate time, electric charge can be reflected on assembly by each photosensitive unit, and the signal that all photosensitive units produce is added together, and just constitutes a complete picture.
As can be seen from such scheme, present invention employs desk lamp neck, instead of complicated physical construction with desk lamp neck and reach flexible object, make the present invention more simple compared to other like product structures; And the also built-in rechargable power supplies of the present invention, when imparting knowledge to students, just need not connect very long line, this is very easy to the use of teaching.
