According to the above technical scheme, the present invention can automatic sensing ambient light and pen holding posture, additionally it is possible to perceive
The current writing duration of writing personnel, and prompting feedback is made after reaching scheduled duration, inform that writing personnel suitably rest.With
It is lower to remind this three functions to make into one for automatic sensing light of the present invention, automatic sensing pen holding posture and writing duration
Step is explained.
Automatic sensing light: firstly, whether the induction ambient light of light sensing module 9 is sufficient；If ambient light is poor, not
Reach the threshold value of light sensing module 9, then the reverse current that photodiode 903 receives is less than predetermined value, that is, receives " dark
Electric current "；If ambient light is good, reach the threshold value of light sensing module 9, then the reverse current that photodiode 903 receives
Greater than predetermined value, that is, receive " photoelectric current ".Then, the optical signal received is converted into electric signal by photodiode 903, and
Electric signal is sent to single-chip microcontroller.In dark, single-chip microcontroller controls micro-machine 5 and inverts, the power of micro-machine 5 via
Power switching device 12 drives pen core 1 to shrink back in nib 2, and writing personnel is prevented to continue to write；When light is bright enough, suitable
When preferably writing, single-chip microcontroller controls micro-machine 5 and rotates forward, and the power of micro-machine 5 drives pen core 1 via power switching device 12
It stretches out outside nib 2.Above-mentioned is to be used to incude ambient light in local invention, and make accordingly for ambient light control pen core 1
The process of movement.More specifically, the course of work of the control of micro-machine 5 pen core 1 extended and retracted is as follows: micro-machine 5
Output power to screw rod 1201, screw rod 1201 drives the first helical gear 1202b being engaged with to rotate after rotating, directly due to first
Gear 1202c is co-axially mounted with the first helical gear 1202b, therefore the first spur gear 1202c's and the first helical gear 1202b is dynamic
Power is synchronous, and the first spur gear 1202c is rotated at this time, drives the second spur gear 1203c being engaged with to rotate, due to third straight-tooth
Wheel 1203b and the second spur gear 1203c is co-axially mounted, therefore the power of the second spur gear 1203c and third spur gear 1203b
Synchronous, third spur gear 1203b is rotated at this time, drives the 4th spur gear 1204b being engaged with to rotate, the 4th spur gear
Rotational pin 1204c is equipped at the lower edge of 1204b, the rotational pin 1204c is used for articulated linkage 4, final third gear set
Eccentric hinged connecting rod 4 does backswing campaign therewith for 1204 drives, and then drive penholder 3 does the stretching motion of rectilinear direction.
Automatic sensing pen holding posture: firstly, whether the induction writing personnel pen holding posture of varistor 13 is correct；As writing people
Clock synchronization, i.e. thumb and index finger are not correctly placed on Anti-skid sheet 15 member's pen holding posture, the pressure that varistor 13 is subject at this time
Less than predetermined value, the resistance value of varistor 13 is greater than predetermined value, and pressure transition is that electric signal is sent to single-chip microcontroller, single-chip microcontroller control
Micro-machine 5 inverts, and the power of micro-machine 5 drives pen core 1 to shrink back in nib 2, prevent book via power switching device 12
The personnel of writing continue to write；When writing, personnel's pen holding posture is correct, and the pressure that varistor 13 is subject at this time is greater than predetermined value, resistance value
Less than predetermined value, pressure transition is that electric signal is sent to single-chip microcontroller, and single-chip microcontroller controls micro-machine 5 and rotates forward, and micro-machine 5 moves
Power drives pen core 1 to stretch out outside nib 2 via power switching device 12.
Write duration to remind: varistor 13 can incude the length of time of compression, if it is pre- to sense that pressing times are greater than
If value, then system is judged as that writing personnel's writing time is too long, then controls linear vibration module 6 by single-chip microcontroller and vibrate, and reminds book
It writes personnel and suitably puts pen rest.The linear oscillator module 6 includes a linear electric machine, and the linear electric machine includes stator and moves
Son, the mover include coil windings 601, and the stator includes steel bar 603, and the strip being fixed on the steel bar 603
Magnet 602, the bar magnet 602 and steel bar 603 constitute track；Brushless connection between the stator and mover, when coil around
After group 601 is powered, travelling-magnetic-field is just generated in air gap, mover will induce electromotive force and generate under traveling wave magnetic field intercepts
Magnetic field phase separation in electric current, the electric current and air gap just generates electromagnetic push, so that mover moves in a straight line, passes through energization
Positive and negative anodes between continuous change, that is, may make that mover does the linear oscillator of linear reciprocation, linear oscillator module 6 is persistently shaken
It is dynamic, so that writing personnel be reminded suitably to rest.
As described above, must not be explained although the present invention has been indicated and described referring to specific preferred embodiment
For the limitation to invention itself.It without prejudice to the spirit and scope of the invention as defined in the appended claims, can be right
It makes a variety of changes in the form and details.

S8, when writing personnel's pen holding posture, clock synchronization, i.e. thumb and index finger are not correctly placed on Anti-skid sheet, at this time varistor
The pressure being subject to is less than predetermined value, and the resistance value of varistor is greater than predetermined value, and pressure transition is that electric signal is sent to single-chip microcontroller, after
The continuous same S5 of step；
S9, when writing, personnel's pen holding posture is correct, and the pressure that varistor is subject at this time is greater than predetermined value, and resistance value is less than predetermined
Value, pressure transition are that electric signal is sent to single-chip microcontroller, the same S6 of subsequent step；
S10, varistor incude compression duration, if sensing, compression duration is greater than preset value, control linear vibration by single-chip microcontroller
The vibration of dynamic model block reminds writing personnel suitably to put pen rest.
