The rechargeable double-key light pen is simple in operation and rich in function, and can be recharged.

Description

A kind of chargeable pair of key light pen

[technical field]

The utility model belongs to a kind of hand input device, specifically is meant the two key light pens that are exclusively used in the infrared-sensing type electronic whiteboard.

[background technology]

Electronic whiteboard is the new high-tech product that has compiled multiple high-tech means research and development such as most advanced and sophisticated electronic technology, software engineering, and it in conjunction with computing machine and projector, can realize with no paper office and teaching through using the different operating principle.

The positioning principle of infrared-sensing type is, launches ultrared blank pen emission infrared ray, and the infrared remote receiver of blank receives the infrared ray that the blank pen sends, and calculates the physical location of this infrared ray on blank then.An infrared blank general utility functions of prior art are more single.

[utility model content]

The utility model technical matters to be solved is to provide a kind of easy to operate, chargeable pair of key light pen of feature richness.

The utility model adopts following technical scheme to solve the problems of the technologies described above:

A kind of chargeable pair of key light pen comprises a housing, and said housing is provided with key behind the preceding key,, a written switch; Be provided with a boost module, a single-chip microcomputer, an infrarede emitting diode, a power module in the said housing; Said single-chip microcomputer is connected with said infrarede emitting diode, said boost module, the preceding key of said pen, said pen back key, said written switch respectively; Said written switch also connects said boost module; Said boost module connects said power module, and said power module also connects a power protection module.

Further, said power module is the 1.5V supplying cell.

Further, said infrarede emitting diode is arranged at the position of said nib.

The advantage of the utility model is:

1. the utility model utilizes power module and boost module that single-chip microcomputer is charged, and single-chip microcomputer produces pulse signal and drives infrarede emitting diode emission IR, and is simple in structure, realizes easily.

2. the utility model can be through a key, pen back key and the multi-functional operation of chip microcontroller before the pen, under the window state: key before: analog mouse left button function, can realize clicking, double-click, drag operation.Pen back key: click a back key, can call the right mouse button function; Double-click pen back key, when not starting IQBoard interactive electronic white board software, this software of automatically starting; Under the cursor state, but key analog mouse left button function before the pen can realize clicking, double-click, drag operation.Pen back key: under any non-paintbrush functional status, click a back key and switch to the paintbrush function; Under any non-paintbrush or blackboard eraser functional status, double-click a back key continuously and switch to the blackboard eraser function; Under the paintbrush functional status, click a back key and switch to the blackboard eraser function; Under the blackboard eraser functional status, click a back key and switch to the paintbrush function.Easy to operate, the feature richness of the utility model.

Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.

Fig. 1 is the utility model system chart.

Fig. 2 is the circuit diagram of boost module in the utility model.

Fig. 3 is the circuit diagram of power protection module in the utility model.

Fig. 4 is the circuit diagram of single-chip microcomputer in the utility model.

[embodiment]

See also Fig. 1, a kind of chargeable pair of key light pen comprises a housing, and said housing is provided with key behind the preceding key,, a written switch; Be provided with a boost module, a single-chip microcomputer, an infrarede emitting diode, a power module in the said housing; Said single-chip microcomputer is connected with said infrarede emitting diode, said boost module, the preceding key of said pen, said pen back key, said written switch respectively; Said written switch also connects said boost module; Said boost module connects said power module, and said power module also connects a power protection module.Said infrarede emitting diode is arranged at the position of said nib.

Two key light pens adopt No. 7 powered battery of common 1.5V output, if directly give circuit supply, very faint of the signal of generation is so adopted boost module to solve this problem.

As shown in Figure 2, be the core circuit of two key light pens.

The utility model charges through electric power source pair of module boost module 1, utilizes the charging process of 2 pairs of power modules of power protection module to carry out charge protection.Boost module 1 adopts the PT1301 DC/DC converter that boosts, theoretical value Vout=(1+R12/R13) * 1.25.We adopt, and (so R12=1.6M is R13=980K) Vout=3.3V.

When written switch 5 is pressed, open boost module 1, it is single-chip microcomputer 3 power supplies that boost module 1 produces highly stable voltage, and the pulse generation module in the single-chip microcomputer 3 produces pulse signal, and pulse signal drives infrarede emitting diode 4 emission IRs.

During keypress function on using two key light pens, nib is pressed before the pen on the electronic pen key 6 or a pen back key 7 and can promptly be realized following respective keys function when touching the plate face:

Under the window state: key 6 before the pen: analog mouse left button function, can realize clicking, double-click, drag operation.Pen back key 7: click a back key, can call the right mouse button function; Double-click pen back key, when not starting IQBoard interactive electronic white board software, this software of automatically starting.

Under window mark pattern, Board pattern, display mode or playback state: key 6 before the pen: under any non-cursor state, click a preceding key 6 and all switch to the selection cursor function; Under any non-cursor state, double-click the preceding key of pen and switch to page expanded function (annotate: this function can only could realize) under the Board pattern.

Under the cursor state, but key 6 analog mouse left button functions before the pen can realize clicking, double-click, drag operation.Pen back key 7: under any non-paintbrush functional status, click a back key and switch to the paintbrush function; Under any non-paintbrush or blackboard eraser functional status, double-click a back key continuously and switch to the blackboard eraser function; Under the paintbrush functional status, click a back key and switch to the blackboard eraser function; Under the blackboard eraser functional status, click a back key and switch to the paintbrush function.
