Abstract

The utility model relates to a video exhibit console with a writing style, in particular to a video object exhibit console which is capable of being convenient to be written on, belonging to education teaching equipment. The utility model is characterized in that the video object exhibit console and writing papers are combined to be a whole by the scientific and reasonable means, resolving the shortcoming that the conventional video object exhibit console is not good for writing operation, thereby users can conveniently write on the video exhibit console, and the utility model is capable of rightly projecting writing contents on the console onto the screen by a projector.

Description

The Writing type video frequency show stand

Technical field

The utility model relates to a kind of Writing type video frequency show stand, especially a kind of video material object display platform of writing that can be convenient thereon.Belong to the education and instruction equipment.

Background technology

Existing video material object display platform all has optical zoom and manual gathering waits camera function.Can show the article on it under normal conditions, and show, the material object of taking in is looked like to be projected on the screen, then writing paper is placed on its table top in the time of writing and write by projector.And this several problems are arranged thereon when writing:

1, to get suitable paper and put thereon, and put positive writing paper according to projector's imaging situation.And the frequent wind-engaging of paper and inevitably touching when writing makes its displacement, deviation position, thus drop shadow effect is write in influence.

2, the size of projection image all need be focused and adjust to each use, and image too greatly then partial content can not show, and is too little then not attractive in appearance and clear.

3, change when operation after every paper has been write, the discontinuous of the interruption of process and content occur.

Summary of the invention

The purpose of this utility model is to provide a kind of video material object display platform of conveniently writing, particularly during teachers ' teaching as long as just can finish writing on the blackboard on this Writing type video frequency show stand writes, the dust atmosphere in the disengaging conventional teaching.

The utility model adopts the way that writing paper is set on existing video material object display platform to realize.Have built-in and two kinds of assembled schemes of external.

Built-in scheme: the utility model is provided with the groove of two installation reels on Writing type video frequency show stand table top, it is protruding to be provided with the corresponding plug-in card that reel is installed in the groove, reel can easily loading, unloading on it, writing paper is wrapped on the two winding drum in advance, writing paper between the reel is flat assists on table top as writing the page, groove is provided with protective cover, lid is equal with table top, lid one side leaves suitable space as exit slot, the protruding axle of plug-in card is gone up and is connected the copper plate that part exposes, thereby drive the reel rotation by copper plate coil paper is moved on table top.

The external scheme: the utility model is provided with two dowel holes on Writing type video frequency show stand table top, reel and writing paper are installed in the external independently rectangular box, the relevant position is provided with two latches on the rectangular box, during use, the rectangular box location is positioned on the video display table top, latch is aimed at corresponding pin-and-hole to be plugged, rectangular box just can be positioned on the default position of show stand, time spent not, rectangular box is mentioned latch and just can easily be taken off from table top, and rectangular box is provided with the rotation that copper plate can be realized paper.

Writing paper is on Writing type video frequency is showed table top, and can the left and right sides rotatable also can be rotatable distribution up and down, and coil paper can be that disposable paper (make by common paper, use up and change coil paper), also can be nonexpondable paper (as plastics goods paper, write, can repeatedly use after clear the wiping) with watercolor pencil.The control copper plate can be the automatically controlled manual mode that also can adopt.And this Writing type material object display platform can be placed on and uses on the common platform, or uses on the special-purpose table, frame, also can be installed on the different shelfs and be used in combination (as being designed to an integral body use with multimedia equipment such as computer).

Fig. 7,8,9 is the outboard profile at three specific function angles of Fig. 6.

Number in the figure is followed successively by:

control copper plate

1,2, plug-in card is protruding 4,5,6,7,

groove

8,9, coil paper 3, reel 10,11.12 for being installed in this Writing type material object display platform on the table of equipment, and 13 is table of equipment.

Embodiment

Referring to Fig. 2, on the Writing type video frequency show stand, establish

groove

8,9, and in

groove

8,9, be provided for the plug-in card protruding 4,5,6,7 of dead block.

Get the rectangular paper 3 of suitable size as Fig. 3, two ends are separately fixed on the

reel

10,11, and Xiang Yiduan spools standby.With 10,11 two ends of the reel among Fig. 3 respectively correspondence be installed on the plug-in card protruding 4,5,6,7, cover recess cover, by changeing the rectangular paper 3 of

copper plate

1,2 tensions, launching flat paper of assisting on video material object display platform table top between reel is exactly to offer the paper that the user writes usefulness.When the user need be skipped, as long as select to rotate the

copper plate

1 or 2 that exposes according to direction, just can drive

reel

10,11 and rotate, realize the moving of rectangular paper 3 on the plate face, make the paper roll of writing go into the reel of an end and the plain pape do not write rolls out from the reel of the other end along the direction that requires.

Fig. 4,5 is an external, and set-up mode is the same, is that groove is set up to box in addition, exactly device shown in Figure 3 is installed in the device of Fig. 5, becomes independently rectangular box, as the device of Fig. 4.In order to locate, open two pin holes on the Writing type video frequency material object display platform table top, offer the latch of two correspondences as correct position on the rectangular box of Fig. 4, two pin holes on the latch aligning video material object display platform table top of Fig. 4 rectangular box are positioned on the video material object display platform, the user just can write easily, also can take off from platform easily in the time of need not writing.
