Abstract
An infrared-ray electronic whiteboard writing pen is characterized in that: the infrared-ray electronic whiteboard writing pen simultaneously supports a hand-press button switch and pen head point press button switch; the infrared-ray electronic whiteboard writing pen is suitable for use on any projection surface; an AAA 1.5V battery is used for supplying power; the pen head of the writing pen is composed of a plugging-replaceable infrared transmitting tube and a plugging-replaceable infrared transmitting tube protecting sleeve; the protecting sleeve can be transparent or non-transparent; a circular hole is provided at the tail part of a pen shaft; and the circular hole is plugged by a protective plug.
Description
Affiliated technical field
The utility model relates to a kind of employing can send the lettering pen that the electronic whiteboard of infrared light supply is used.
Background technology
At present, known infrared-type all needs to adopt the infrared ray lettering pen to complete computer operating function and writing function without the screen electronic whiteboard.Distinguishing according to the action type of power switch has two classes, i.e. " the infrared pen of hand push type " and " the infrared pen of knock type ".
Pin power switch when the infrared pen of hand push type need to or be write at operating computer, decontrol when not required power switch.The shortcoming of this " hand push type pen " is that whole writing process need to carry out pressing and unclamping of switch frequently, if coordinate the bad bad word of just writing, the user needs certain training and training use procedure, has increased the complicacy of using, and advantage is to use on the projection screen that suspends.
The infrared pen of knock type does not need to remove push switch with hand, and switch is directly installed on pen head part, presses nib and just can begin to write when writing, and lifts nib and has just completed and write, and it is duplicate that whole use procedure is used common with us.It is simple that this " knock type pen " has use, the advantage such as easy and simple to handle, but shortcoming is because need to be nib by being pressed in projection surface, therefore need the strength of some touch switch to act on projection surface, if projection surface is the projection screen that suspends, any small strength all can cause waving of curtain, causes the difficulty of writing, and therefore this mode is not suitable for using on the projection screen that suspends.
Summary of the invention
The utility model combines the function of hand push type and two kinds of lettering pens of knock type, namely supports simultaneously touch the button switch and nib of hand to press pushbutton switch, is adapted at using in any projection surface.
But but the infrared transmitting tube protective sleeve that the infrared transmitting tube that the lettering pen nib is changed by plug and plug are changed form, protective sleeve can be transparent, can be also opaque.
At shaft of a writing brush afterbody, a circular hole is arranged, this circular hole is thrust by a protection and clogs.
The utility model adopts No. 7 1.5V dry cells of a joint as power supply.
Technical scheme
The utility model adopts two microswitches to control the switch of infrared emission tube.The method that pen head part adopts spring to add microswitch realizes " knock type " operation.The triggering strength of microswitch is very light, and only less than 15 grams, the actual triggering strength of nib is controlled by spring.
" hand push type " of pen operates and realized by a hand switch button, and this hand switch button connects with parallel way with the microswitch of being connected, and any one switch all can be controlled the switch of infrared emission tube like this.
The utility model adopts No. 7 1.5V dry cells of a joint as power supply, does not need to increase resistance.
Beneficial effect
The beneficial effects of the utility model are can use the utility model and write on any soft or hard writing surface.
Description of drawings

Fig. 2 is sectional view of the present utility model
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof, use of the present utility model is described further:
In Fig. 1,1, the nib of lettering pen, 2, the hand switch button.During use, directly press the power supply that nib 1 or finger presses button 2 can be connected lettering pen.
In Fig. 2,1, written protective sleeve, 2, infrared transmitting tube, 3, spring, 4, nib presses microswitch, 5, the fixing circular hole of wiring board, 6, battery case, 7, binding post, 8, extension rod jack protection plug.Nib protective sleeve 1 is enclosed within infrared transmitting tube 2 outsides; protection infrared transmitting tube 2 is not worn; power valve 2 directly is inserted into above the binding post 7 of nib the inside when installing, and at spring 3 of binding post 7 outsides installations, spring 3 is used for adjusting the dynamics size that nib is pressed triggering.Binding post 7 is arranged on by wire on the both positive and negative polarity wiring pad of wiring board to obtain powered battery.Nib is against above microswitch 4, when writing, presses nib 1, and nib compresses microswitch 4 toward shaft of a writing brush the inside extruding, turn-on power, and infrared emission tube 2 is luminous.When unclamping written 1, spring handle nib 1 ejects, microswitch 4 also simultaneously automatic loosening cut-off switch power supply, infrared emission tube 2 is not luminous.Battery is arranged on battery case 6 the insides, and circuit board is by the fixing definite position of circular hole 5.At shaft of a writing brush afterbody, a circular hole is arranged, can insert a retractable pointer that is used for extending lettering pen, circular hole without the time clogged by a protection plug 8.
