Abstract

The utility model relates to a multi-purpose laser teaching pen solving the problem that a traditional teaching pen can not be used for teaching on a blackboard. One end of a pen body (2) is provided with a pen point (1) which is connected with a pen refill (3), the other end of the pen body (2) is provided with a laser emission head (10) which is connected with a component (9) on a circuit board (8), a spring (4) is arranged in the pen body (2) and is connected with the pen refill (3), and a battery (5) and the circuit board (8) are connected with a first switch (6) and a second switch (7).

Description

The multi-purpose laser teaching pen

Technical field:

The utility model is relevant with teaching appliance, and especially to correct pen relevant with laser indication and teaching.

Background technology:

Now, teacher for the content that writes on the blackboard, in the time will emphasizing that emphasis will be put, remains by going on the dais when teaching, and hand is pointed on blackboard.Existing problems have like this:

1, always there are one or both sides to block student's sight line about, make to see clearly and note down with inconvenience.

2, increase teacher's the momentum of walking, just under a strain, more arduous originally.

3, must increase the lime dust soakage near blackboard, health is caused bigger influence.

4, teacher signature and correcting students' papers will have coloured pencil (as redness) in addition, burden and losing easily.

The utility model content:

The purpose of this utility model provides and a kind ofly both can be used for writing and correct students' papers this, can be used for the multi-purpose laser teaching pen of black board teaching again.

The utility model is achieved in that

The utility model multi-purpose laser teaching pen, one end of handwriting 2 has nib 1 to link to each other with pen core 3, the other end has laser beam emitting head 10 to link to each other with components and parts 9 on the circuit board 8, spring 4 and dividing plate 3 welding are arranged in the handwriting 2, dividing plate links to each other with pen core, has battery 5 to link to each other with the 2nd switch 7 with circuit board the 8, the 1st switch 6.

Circuit board 8 has the stroboscopic oscillating circuit, and battery 5 one tunnel outputs are connected with laser beam emitting head through the 1st switch 6, and another road output of battery is connected with laser beam emitting head with the stroboscopic oscillating circuit through the 2nd switch 7.

The capacitance-resistance charge-discharge circuit and the 1st that the stroboscopic oscillating circuit is made up of resistance and electric capacity, 2 transistorized base stages are connected with colelctor electrode, and the 1st, 2 transistorized collector and emitters connect the input of laser beam emitting head.

The utility model is simple in structure, and cost is low holds concurrently, easy to use, and pen core is red (also can be other color) in the handwriting, is convenient to teacher and writes, signs and use when revising operation.Laser head emission on the handwriting can be used in black board teaching, and the especially stroboscopic of the stable irradiation of switch 1 and switch 2 irradiation can be done the differentiation of different levels and emphasis main points.

The laser teaching pen helps teacher teaches, and makes emphasis and guides, and needn't go up the dais, does not block blackboard, absorbs benefits such as dust less; Also help the observation of students record, luminous point flashes also can reduce fatigue, improves the interest etc. of listening to the teacher, conjuncted with lettering pen in addition, and multi-function action is arranged.

Description of drawings:

Fig. 1 is the utility model structure chart.

Fig. 2 is a circuit block diagram of the present utility model.

Fig. 3 is the utility model circuit theory diagrams.

The specific embodiment:

One end of handwriting 2 of the present utility model has nib 1, and the other end has laser beam emitting head 10.Pen core 3, spring 4, battery 5 and circuit board 8 are arranged in the handwriting.Switch 6,7 is arranged on the handwriting.

All components and parts 9 are contained on the miniature printed circuit board, and from Fig. 2 as seen, this laser teaching pen is mainly by being connected in series power supply, switch 1 and switch 2, laser beam emitting head, stroboscopic oscillating circuit composition.

Fig. 3 then is the enforcement circuit of this laser teaching pen.As we can see from the figure, three 1.5V button cells are connected in series, and constitute dc supply.

Power supply is through duplex feeding, and one the tunnel through switch 1, behind the dropping resistor R1, directly lights laser head, launches a branch of ruddiness.Different with luminous tube is, this Shu Hongguang does not disorderly loose, and brightness do not subtract substantially in ten meters scopes, and shines and form the luminous point that diameter is about 3 centimetres on the object, so very suitable replacement gesture instructs emphasis.

Another road of power supply is transported to frequency oscillator through switch 2, this oscillator is through the capacitance-resistance charge-discharge circuit of R3, C2 and R4, C3 formation, cooperate the break-make upset of transistor BGI, BG2, formation is to the intermittent power supply of laser tube, its effect is to produce to flash effect, bright, stop now being made as blanking time 1/4 second, also can change resistance, hold parameter, the adjustment time.

K1, K2 are two not lock-switch, press work, and the disconnection of loosing one's grip is in order to economize on electricity.

Stable irradiation and stroboscopic irradiation had both helped that teacher does gently, emphasis is distinguished, and again with change, flexible way, the innervation of mobilizing students consciousness reduces the sense organ fatigue of long-time formation, and the raising interest etc. of listening to the teacher is so be another design that acquires a special sense.
