Traditional electronic teacher pointer can be realized the effect of laser designation, such as patent No. ZL03251003.9, discloses a kind of electronic teacher pointer, can realize the laser tracking; Other can be regulated the volume, brightness etc. of multimedia presentation system by manual overvide in explanation, such as ZL200420014950.1.Above-mentioned teacher's pointer is used to refer to the explanation position and regulates the brightness of explanation content or the operations such as volume of sounding.

But all there are some defectives in these electronic teacher pointers of tradition, show as following deficiency:

1. function singleness is relatively simple for structure, although can use, the defective of function is not enough to finish various functions.

2. can only realize deixis, to the explanation content carry out other operations, the speaker must operate by computer, and the speaker is limited in around the computer, if go to exchange with everybody in the auditoria just very inconvenient.

3. operating process is loaded down with trivial details, the separate device switching manipulation, complex redundancy.

4. in the face of new multimedia operations the time, be not enough to finish various types of operations, such as the page turning of PPT, displaying video animation etc.

In order to overcome the deficiencies in the prior art, resolve the problem of prior art, remedy the existing in the market deficiency of existing product.

The utility model provides a kind of pulley control electronic teacher pointer, comprise a plurality of signal buttons and the function selecting key that arrange on main body and the main body, wherein, the signal controlling key is arranged on the upper area of main body, function selecting key is arranged on the central region of main body, lower area in main body is provided with frequency key and power key, be provided with signal projector and signal receiver on the top of main body, body interior is provided with main control module, circuit module, to frequency module and power module, between to frequency key and power key, be provided with chute, be provided with roller in the chute, described roller is connected with main control module.

Preferably, above-mentioned signal controlling key comprises and AV signal switch key, master control key are set, receive key and emission key.

Preferably, the above-mentioned functions options button comprises multifunction key, directionkeys and acknowledgement key.

Preferably, above-mentioned main control module is connected with circuit module, described frequency module is connected by circuit module with power module be connected with main control module.

Preferably, be provided with the signal condition pilot lamp between above-mentioned AV signal switch key and the reception key.

Preferably, be disposed with connection state pilot lamp and power state pilot lamp under the above-mentioned signal condition pilot lamp.

Preferably, also be provided with the first online indication LED and the second online indication LED in the aforementioned body, the described first online indication LED be connected online indication LED and be connected with main control module by circuit module respectively.

The pulley control electronic teacher pointer that the utility model provides is compared with traditional electronic teacher pointer, by being arranged on the roller between frequency key and the power key, the user can with operations such as roller carry out that the page turning of screen, the amplification of picture are dwindled, be similar to mouse to the pulley operation of computer.
