Embodiment
For making purpose of the present invention, structure, feature and function thereof there are further understanding, hereby cooperate embodiment to be described in detail as follows.
Referring to figs. 1 through shown in Figure 5, the first technical scheme of the present invention provides a kind of projection pen 100, is used at the enterprising line operate of projection screen (not shown in FIG.), and this projection pen 100 comprises protecgulum 1, resettlement section 2, switch portion 3 and housing 4.This protecgulum 1 is flexibly connected mutually with this housing 4, can produce between the two to relatively move, and this resettlement section 2 and this switch portion 3 are positioned at this housing 4.Wherein projection screen can be custom-designed touch-screen, also can be the curtain that is used with projector or glass wall etc.; The operation of projection pen 100 on projection screen can be to click, and also can be to write etc.
Above-mentioned this resettlement section 2 and this switch portion 3 are fixed in the inboard of this housing 4.This resettlement section 3 directly can be fixed in this housing 4, also this switch portion 3 directly can be fixed on this housing 4 inboards.
In addition, for effectively pressing of the contact 310 that guarantees this guide rail 13 and this switch portion 3, when the design original state, the stroke that this guide rail 13 moves to this contact 310 equals the length L identical (as shown in Figure 3) of this shift space.
In addition, this projection pen 100 also is provided with push-button unit, this push-button unit comprises button 60, keypad 61, button circuit board 62, this button 60 is fixed on this keypad 61, this keypad 61 is electrically connected mutually with this button circuit board 62, and this keypad 61 and this button circuit board 62 are positioned at this housing 4; This button 60 is positioned at the accommodation hole (not shown in FIG.) of this housing 4 to be located, and this button comprises acknowledgement key, light key etc., for the user.
The battery 8 that this projection pen 100 also further is provided with main circuit board 7 and is connected with this main circuit board 7, this battery 8 are used for to 7 power supplies of this main circuit board; This main circuit board 7 and this battery 8 are positioned at this housing 4 inside, and this main circuit board 7 fixes with this housing 4.In addition, the switch 31 of this main circuit 7 and this button circuit board 62 and this switch portion 3 is electrically connected.
The below will be described further the principle of work of projection pen 100 of the present invention.When this projection pen 100 during at the enterprising line operate of this projection screen, this nib 10 is subject to the pressure that projection screen transmits, and this pressure passed to this guide rail 13, the direction of backward this switch portion 3 of these guide rail 13 pressurizeds moves until contact the contact 310 of switch 31 of this switch portion 3 so that this switch 31 is in conducting state, thereby the connection conducting of this switch 31 that makes and this main circuit board 7 can be carried out the function of projection pen; And in the process that this guide rail 13 moves, this guide rail 13 is that the gathering sill 22 along this resettlement section 2 moves, so that the contact 310 of this guide rail 13 and this switch portion 3 can both contact, thereby guarantees the conducting of the switch 31 of this switch portion 3.Even if so so that nib 12 and this projection screen tilt, also can so that the contact 310 of this guide rail 13 and this switch portion 3 contacts, guarantee that the operation of projection pen 100 is smooth.When this projection pen 100 broke away from this projection screen, this guide rail 13 separated with the contact 310 of this switch portion 3, and this switch portion is in off-state, and this moment, this guide rail 13 still moved along the gathering sill 22 of this resettlement section 2, was returned to initial position.
The second technical scheme of the present invention also provides a kind of projection interaction systems, and this projection interaction systems comprises projector and projection pen.This projection pen is used at the enterprising line operate of projection screen, produces signal and this signal is passed to this projector, know for the existing technical staff at the interaction theory of this this projector and this projection pen, and or not the emphasis that the present invention describes, do not repeat them here.The structure that is this projection pen that the present invention pays attention to describing is the projection pen described in the first technical scheme, does not repeat them here.
The present invention is described by above-mentioned related embodiment, yet above-described embodiment is only for implementing example of the present invention.Must be pointed out that the embodiment that has disclosed does not limit the scope of the invention.On the contrary, the change of doing without departing from the spirit and scope of the present invention and retouching all belong to scope of patent protection of the present invention.
