Abstract
The utility model discloses a structure for preventing handwriting pen from being lost of electronic device. A slot which is used to install the handwriting pen is arranged on the electronic device. A sense switch is arranged in the slot. The sense switch is electrically connected with the control circuit of the electronic device. When the handwriting pen is arranged in the slot, the handwriting pen presses the sense switch to make the sense switch transmit the pressed signal to the control circuit. When the handwriting pen is not arranged in the slot, the sense switch transmits the non pressed signal to the control circuit because the sense switch is not pressed and electronic device is closed or is not used for some time. The sense switch continuously transmits the non pressed signal to the control circuit. The control circuit actuates a sounding circuit which broadcasts the caution sound to remind the user to put the handwriting pen in the slot. So, the reminding of the caution sound prevents the handwriting pen from being lost.
Description
Technical field
The utility model relates to a kind of electronic installation writing pencil and prevents the structure lost, especially be provided with a sense switch in the slot of a kind of this electronic installation of finger, when this electronic installation is shut down or is not used a period of time, and when this sense switch continues to sense this writing pencil and is not installed in this slot, this electronic installation will send caution sound, with the prompting user this writing pencil is put back in this slot, and then prevented the device that this writing pencil is lost.
Background technology
General commercially available portable electronic apparatus (as: personal digital assistant device (PDA)) mostly has touch-screen (Touch Screen), make the user can utilize the writing pencil of this electronic installation, on this screen, import font, drawing, or click option on the software of this electronic installation, so that being used as slide-mouse, uses by this writing pencil.
The manufacturer of general personal digital assistant device; in order to protect its screen better; all adopt special material to make this writing pencil; therefore this screen is limited only can use this writing pencil; import; if use other non-writing pencils to import, will cause the injury (as: surperficial scratch) of this screen.But, because this writing pencil uses frequently, after use finishes, forget the slot of putting back to this writing pencil easily, thereby cause losing the problem that causes no writing pencil to import.So, how to solve the problem that writing pencil is lost easily, and design a kind of structure that prevents that writing pencil from being lost, will be the problem that the electronics industry is demanded urgently making great efforts.
The utility model content
The utility model people is because the problem that aforementioned writing pencil is lost easily, be manufacturing experience and the technology accumulation of being engaged in electronic installation according to it, method at the various solutions of the concentrated research of above-mentioned disappearance, studying through continuous, after experiment and the improvement, finally development and Design goes out a kind of electronic installation writing pencil of the present utility model and prevents the structure lost, this structure is to be provided with one for the slot that writing pencil is installed on this electronic installation, be provided with a sense switch in this slot, the control circuit of this sense switch and this electronic installation is electrically connected, order is when this writing pencil is installed in this slot, this writing pencil will press this sense switch, make this sense switch transmit touched signal to this control circuit, and when this writing pencil is not installed in this slot, this sense switch will be because of not touched, and transmit not touched signal to this control circuit, make this electronic installation be shut down or not be used a period of time, and the not touched signal of this sense switch sustained delivery is during to this control circuit, this control circuit will start a phonation circuit, play caution sound, to remind the user that this writing pencil is put back in this slot, so, by the prompting of this caution sound, reach the purpose that prevents that this writing pencil from being lost.
One of the utility model purpose, be that this electronic installation is provided with a switch between this control circuit and this sense switch, it is conducting state that the user can press this switch, make that this sense switch is an opening, perhaps pressing this switch is off state, making this sense switch is closed condition, and so, the user can use this switch open or close this sense switch.
For ease of to the purpose of this utility model, shape, constructing apparatus feature and effect thereof, do further understanding and understanding, for the embodiment conjunction with figs., be described in detail as follows now:
Description of drawings
Fig. 1 is one of block schematic diagram of the present utility model.
Fig. 2 is two of a block schematic diagram of the present utility model.
Fig. 3 is a circuit box synoptic diagram of the present utility model.
Embodiment
The utility model is that a kind of electronic installation writing pencil prevents the structure lost, see also Fig. 1, shown in 2, be at this electronic installation (as: PDA(Personal Digital Assistant), the mobile phone of tool personal digital assistant ... etc.) (not shown) is provided with one for the slot 12 that writing pencil 11 is installed, be provided with a sense switch 13 in this slot 12, please consult Fig. 2 again, shown in 3, this sense switch 13 is electrically connected with a control circuit 14 of this electronic installation, order is when this writing pencil 11 is installed in this slot 12, this writing pencil 11 will press this sense switch 13, make this sense switch 13 transmit touched signal to this control circuit 14, and when this writing pencil 11 is not installed in this slot 12, this sense switch 13 will be because of not touched, and transmit not touched signal to this control circuit 14.
The composition of the above-mentioned member of mat, see also again shown in Fig. 1,3, when this electronic installation is shut down or is not used a period of time, and this sense switch 13 is not touched, and the not touched signal of sustained delivery is during to this control circuit 14, this control circuit 14 will start a phonation circuit 15, play caution sound, to remind the user this writing pencil 11 is put back in this slot 12, so, by the prompting of this caution sound, reach the effect that prevents that this writing pencil 11 from being lost.
In the utility model, see also shown in Figure 3 again, this electronic installation is provided with a switch 16 between this control circuit 14 and this sense switch 13, the user can press this switch 16 and be conducting state, make this sense switch 13 be opening, perhaps press this switch 16 and be off state, make this sense switch 13 be closed condition, so, the user can open or close this sense switch 13 according to this switch 16 of its demand utilization, when the need prompting is put back to this writing pencil 11 in this slot 12, opens this sense switch 13, not reminding when putting back to this writing pencil 11 in this slot 12, close this sense switch 13.
In addition, see also again shown in Fig. 1,2, this sense switch 13 can be a spherical pushbutton switch, spherical button by this spherical pushbutton switch, when making this writing pencil 11 be installed in this slot 12, press this sense switch 13 easily, and this writing pencil 11 is left this sense switch 13 easily by when extracting in this slot 12.
