Another object of the present invention comprises a plurality of pen cores, shell, coil and circuit board in that a kind of many pen cores pressure sensing type time writer is provided, and wherein said pen core is covered by in the shell; Coil is wrapped on the shell and is connected to circuit board, and circuit board is positioned at the tail end of pen core, and the magnetic penholder of each pen core is constituted by different magnetic materials; Therefore; When the actuating mechanism of pen core made nib expose shell outer through promotion, the magnetic penholder can fall in the magnetic field of coil, makes coil produce the inductance value of equivalence; And different pen cores have different inductance value; Therefore the inductance value of serial connection and the capacitance of circuit board can change the transmission frequency of time writer, and make many pen cores pressure sensing type time writer have the function of different colours.
Description of drawings
Following conjunction with figs. and component symbol are done more detailed explanation to embodiment of the present invention, can implement according to this after studying this instructions carefully so that have the knack of this operator, wherein:
Fig. 1 is the synoptic diagram of many pen cores pressure sensing type time writer of first embodiment of the invention.
Fig. 2 is the synoptic diagram of many pen cores pressure sensing type time writer of second embodiment of the invention.
Embodiment
Consult Fig. 1, the synoptic diagram of many pen cores pressure sensing type time writer of first embodiment of the invention.As shown in Figure 1; Many pen cores pressure sensing type time writer of the present invention comprises a plurality of pen cores (like first pen core 10 and second pen core 20 among the figure), a plurality of sensing element (like first sensing element 31 and second sensing element 32 among the figure), shell 30, coil 40, circuit board 50; Wherein first pen core 10 and second pen core 20 are to be coated in the shell 30; Coil 40 is wrapped on the shell 30 and is connected to circuit board 50, and circuit board 50 is the tail ends that contact first pen core 10 and second pen core 20 respectively with first sensing element 31 and second sensing element 32.
Be noted that; Be convenient explanation characteristic of the present invention; Present embodiment is to be used as exemplary embodiment with two pen cores (that is first pen core 10 and second pen core 20) and two sensing elements (that is first sensing element 31 and second sensing element 32) to do explanation; But be not that therefore in fact, the number of pen core and sensing element can be any positive integer in order to the qualification scope of the invention.
Sensing element can be switch or shell fragment.
First pen core 10 has nib 11, magnetic penholder 13, elastic component 15 and actuating mechanism 17; And second pen core 20 has nib 21, magnetic penholder 23, elastic component 25 and actuating mechanism 27; Wherein nib 11, magnetic penholder 13, elastic component 15 and actuating mechanism 17 are to be combined as a whole, and nib 21, magnetic penholder 23, elastic component 25 and actuating mechanism 27 also are combined as a whole.
When the actuating mechanism 17 of first pen core 10 moves through promotion and toward nib 11 directions; The nib 11 of first pen core 10 can exceed the coating scope of shell 30 and expose; User's many pen cores pressure sensing type time writer of the present invention capable of using is by nib contact number letter stencil (not shown) or let nib be positioned on the position of a certain distance in digiboard top, to carry out writing words or drawing.Elastic component 15 can be coil component spring, cone shaped spring (Conical Coil Spring) or rubber (Rubber); The application of force with 11 pairs of digiboards of buffering nib; Make many pen cores pressure sensing type time writer of the present invention have the pressure-sensitive function; Also can be by the style of writing application of force of nib 11 size, and demonstrate the depth and the thickness of lines.
Because the actuating mechanism that is pushed 17 can break away from first sensing element 31, circuit board 50 to be switching to corresponding capacitance, such as the corresponding electric capacity of a plurality of electric capacity in succession, or changes the area of electric capacity, or changes the cross-pressure of variable capacitance.The mode that is noted that the capacitance of above-mentioned commutation circuit plate 50 is not in order to limiting scope of the present invention, that is the present invention also can use the capacitance of other mode with commutation circuit plate 50.
The inductance value of coil 40 forms with the capacitance of circuit board 50 and is connected in series, and therefore, many pen cores pressure sensing type time writer of the present invention can produce transmission frequency f according to following formula:
f = 1 / ( 2 π LC )
Wherein L is the inductance value of coil and C is the capacitance of circuit board.
So; If promote the actuating mechanism 27 of second pen core 20; Then nib 21 can expose shell 30, and actuating mechanism 27 meeting disengagings second sensing element 32, makes circuit board 50 switch to another corresponding capacitance; To change the transmission frequency f of many pen cores pressure sensing type time writer, reach that single time writer has the different transmission frequencies of emission so that on showing, demonstrate the purpose of different colours.
In addition; Shell 30 can form shell thing 33 in front end area; Shell thing 33 can be plastics or metal constitutes, and wherein two ends of shell thing 33 have first convex 35 and second convex 37 respectively, wherein first convex 35 near nib second convex 37 away from nib.Coil 40 is the zones that envelope between first convex 35 and second convex 37, and can further have groove away from second convex 37 of nib, in order to fixed coil 40.
Consult Fig. 2, the synoptic diagram of many pen cores pressure sensing type time writer of second embodiment of the invention.As shown in Figure 2; Many pen cores pressure sensing type time writer of the present invention comprises a plurality of pen cores (like first pen core 70 and second pen core 80 among the figure), shell 30, coil 40, circuit board 50; Wherein first pen core 70 and second pen core 80 are to be coated in the shell 30, and coil 40 is wrapped on the shell 30 and is connected to circuit board 50.First pen core 70 has nib 71, magnetic penholder 73, elastic component 75 and actuating mechanism 77; And second pen core 80 has nib 81, magnetic penholder 83, elastic component 85 and actuating mechanism 87; Wherein nib 71, magnetic penholder 73, elastic component 75 and actuating mechanism 77 are to be combined as a whole; Nib 81, magnetic penholder 83, elastic component 85 and actuating mechanism 87 also are combined as a whole, and magnetic penholder 73 has different magnetic materials with magnetic penholder 83.
With Fig. 1 relatively, second embodiment is except the sensing element that saves first embodiment and the magnetic penholder that uses different magnetic materials, other member is identical with first embodiment of Fig. 1, so identical functions repeats no more.
If promote the actuating mechanism 77 of first pen core 70; Then nib 71 can expose shell 30, and magnetic penholder 73 can fall into the magnetic field of coil 40, makes coil 40 have corresponding inductance value; And this inductance value forms with the capacitance of circuit board 50 and is connected in series, and therefore can produce transmission frequency f.If promote the actuating mechanism 87 of second pen core 80, then magnetic penholder 83 can fall into the magnetic field of coil 40, makes coil 40 have another corresponding inductance value, produces another transmission frequency f.Therefore, can change transmission frequency f, have the function that on display, shows different colours to realize single time writer by the magnetic penholder of different magnetic materials.
Above-described being merely in order to explain preferred embodiment of the present invention; Be not that attempt is done any pro forma restriction to the present invention according to this; Be with, all have in that identical invention spirit is following do relevant any modification of the present invention or change, all must be included in the category that the invention is intended to protect.
