The present invention relates to a timepiece with handwriting input unit, and more particularly to a timepiece that allows a user to handwrite characters on a handwriting input unit, so as to very easily and conveniently input and set an alarm time for the timepiece.
In a conventional alarm clock, a mechanical type “hand” is turned to set a time for emitting an alert sound. When the set alarm time is reached, related internal components are actuated, so that a sound emitting mechanism emits sound. The alarm clock with the above-described alarm time setting structure might very possibly have a failed alarm module due to improper mechanism design or improper operating manner.
There are also electronic alarm clocks and watches, which require complicate procedures and a lot of time to correctly set a desired alarm time.
Moreover, all the currently available alarm clocks are generally set to alarm in the above mentioned manners without special changes.
Therefore, it is desirable to develop a timepiece that can be set to alarm in a novel and convenient manner.
A primary object of the present invention is to provide a timepiece with handwriting input unit, so that a user may handwrite numerical characters on the handwriting input unit to very easily and conveniently input and set an alarm time for the timepiece.
Another object of the present invention is to provide a timepiece with handwriting input unit, which also includes a temperature sensing element for sensing an ambient temperature, so that the timepiece also provides information about ambient temperature.
To achieve the above and other objects, the timepiece with handwriting input unit according to the present invention includes a micro control unit (MCU) for controlling the movements of all other components of the timepiece; a timekeeping unit connected to the micro control unit; a display unit connected to the micro control unit for showing a message sent thereto by the micro control unit; a handwriting input unit connected to the micro control unit for inputting a handwritten instruction; and a sound emitting mechanism connected to the micro control unit for receiving a signal from the micro control unit and emitting a sound.
The micro control unit is internally provided with a temperature sensing element for sensing an ambient temperature, which is then sent to the micro control unit and shown on the display unit.
In a preferred embodiment, the timepiece is provided with a control button, which is connected to the micro control unit. When the timepiece emits sound, the control button may be pushed to delay the sounding of the timepiece.
In an ideal embodiment, the handwriting input unit is formed of a carbon powder layer, a duplicating layer, and a sensing circuit layer. The sensing circuit layer is an identifying system having a sensing circuit, which uses an internally preset identifying module to identify handwritten characters sequentially input via the handwriting input unit.
A user may use the handwriting input unit to quickly and conveniently input and set an alarm time through handwriting without involving in complicate setting procedures. Therefore, the timepiece of the present invention is indeed a novel technical design practical and convenient for use.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein

Wherein, the micro control unit 11 is a microprocessor chip.
The micro control unit 11 is internally provided with a temperature sensing element 16 for sensing an ambient temperature, which is then sent to the micro control unit 11 and shown on the display unit 13.
In a preferred embodiment, the timepiece 10 is provided with a control button 17, which is connected to the micro control unit 11. When the timepiece 10 emits sound, the control button 17 may be pushed to delay the sounding of the timepiece 10.
In an ideal embodiment, the handwriting input unit 14 is formed of a carbon powder layer 141, a duplicating layer 142, and a sensing circuit layer 143. The sensing circuit layer 143 is an identifying system having a sensing circuit, which uses an internally preset identifying module to identify handwritten characters sequentially input via the handwriting input unit 14.

When the handwritten characters are input and the micro control unit 11 receives and verifies a signal from the handwriting input unit 14, an instruction is sent by the micro control unit 11 to the sound emitting mechanism 15. After the instructed time is set in the sound emitting mechanism 15 by internal modules thereof, the exact time for emitting the alert sound may be correctly returned and reported to the micro control unit 11.
With the handwriting input unit 14 provided on the timepiece 10, a user may intuitionally and quickly input and set an alarm time via the handwriting input unit 14 without involving in complicate setting procedures that would otherwise occur in other types of alarm watches or clocks. And, an earlier setting may be conveniently erased via the magnetic reed switch 18.
Therefore, the timepiece 10 of the present invention is indeed a novel technical design practical and convenient for use.
The present invention has been described with some preferred embodiments thereof and it is understood that many changes and modifications in the described embodiments can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
