Abstract
The utility model discloses an infrared electronic pointer, which comprises a handle. A telescopic rod with an LED (Light-Emitting Diode) nib and a power supply device supplying power for the LED nib are arranged in the top of the handle, wherein the power supply device is a button battery. A battery chamber is arranged in the front end, which replaces the design that two dry batteries are arranged in the rear end in a present pointer; and power is supplied by the button battery instead of the dry batteries in the present pointer; thus, the length of the pointer is greatly reduced in structure.
Description
Technical field
The utility model relates to a kind of instrument for education sector, particularly relates to a kind of infrared exoelectron teacher's pointer.
Background technology
At present, the electronic whiteboard of many type of skills all uses electronic pen or electronic teacher pointer as writing implement, opto-electronic image processing formula electronic whiteboard for example, adopt electronic pen or teacher's pointer as writing implement, in general, the length of electronic pen is shorter, be fit to writing of small-size screen, inconvenience is write at giant-screen, and electronic teacher pointer is more suitable for being used in and punctuates on the large scale screen and indicate, electronic teacher pointer comprises, expansion link 6, and the end of this expansion link 6 is provided with handle 8, the top of this expansion link 6 is provided with LED nib 5, carry two joint dry cells 9 in the described handle 8, be provided with power switch 7 at this handle 8, but because electronic teacher pointer is oversize, even if electronic teacher pointer shortens to minimum, length is also more than 30cm, and the optimum length of lettering pen is within 15cm, and therefore existing electronic teacher pointer can't present the writing effect the same with electronic pen.
In view of the defective that above-mentioned existing electronic pen or electronic teacher pointer exist, the design people, actively research and innovation in addition in the hope of founding a kind of infrared exoelectron teacher's pointer of new structure, makes it have more practicality.
The utility model content
Fundamental purpose of the present utility model is, overcome the defective that existing electronic pen or electronic teacher pointer exist, and a kind of infrared exoelectron teacher's pointer of new structure is provided, technical matters to be solved is to make its volume little, thereby more practical, and has value on the industry.
The purpose of this utility model and solve its technical matters and realize by the following technical solutions.Infrared exoelectron teacher's pointer according to the utility model proposes comprises handle, and the top of this handle is provided with the expansion link of LED nib and the supply unit of power supply to the LED nib is provided.
Aforesaid infrared exoelectron teacher's pointer, wherein, described supply unit is button cell.
By technique scheme, the utility model infrared exoelectron teacher's pointer has following advantages at least:
Place the design that supply unit replaces the two joint dry cells of placing existing teacher's pointer rear end with front end, and the mode of button cell power supply replaces the dry cell power supply mode of existing teacher's pointer, greatly reduced the length of teacher's pointer from structure.
In sum, the infrared exoelectron teacher's pointer of the utility model special construction, it has above-mentioned many advantages and practical value, thereby more is suitable for practicality.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, and preferred embodiment of the present utility model also cooperates accompanying drawing to be described in detail as follows.
Description of drawings
Fig. 1 is the structural representation of traditional infrared exoelectron teacher's pointer.
Fig. 2 is the structural representation of infrared exoelectron teacher's pointer described in the utility model.
Embodiment
Be to reach technological means and the effect that predetermined utility model purpose is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, embodiment of the present utility model be described in detail as follows.
As shown in Figure 1, the infrared exoelectron teacher's pointer, comprise handle 3, the top of this handle 3 is provided with the expansion link 4 of LED nib 1 and the supply unit 2 of power supply to the LED nib is provided, supply unit 2 is button cell, the battery compartment that front end is placed replaces the battery compartment design of placing existing teacher's pointer rear end, the dry cell power supply mode that replaces existing teacher's pointer with the mode of button cell power supply, greatly reduced the length of teacher's pointer from structure, when infrared exoelectron teacher's pointer of the present utility model is retracted to shortest length, the infrared exoelectron teacher's pointer can be used as the electronics light pen, the user can directly carry out character calligraph at the projection screen that electronic white board equipment is arranged, the mark of punctuating, when projection screen was larger, the user can manually elongate expansion link 4, is then holding the infrared exoelectron teacher's pointer, click screen with LED nib 1 again, just can realize punctuating marks and the function of character calligraph.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
