Description
Technical field
The utility model relates to electricity and microcomputer applied technical field, relates in particular to the manual regulating device of image parameters such as a kind of thickness that is used to regulate the handwritten patterns track on touch-screen or electronic whiteboard, color.
Background technology
Electronic whiteboard is a kind of office automation meeting equipment, and its purposes is similar to the conventional teaching blackboard, and in work and life, people usually need practical blank to finish record or item is discussed.Along with development of electronic technology, no matter be the environment of giving lessons, or in the investigation process of department in school, beginning is practical electronic whiteboard.The symbol that this product can write on the blackboard book in time transfers electric signal to, is input in the computing machine that is connected, and directly finishes remote information exchanges such as editor, printing, transmission again by computing machine.
In the practical process of electronic whiteboard, we want frequent replacing to write the next vivider intention that gives expression to the lecturer of various image parameters such as the thickness of lines, actual situation line, but in existing electronic whiteboard, we can only computer monitor shown on the image parameter option in change, practise in some situation, use very inconvenient.
The utility model content
In order to solve the shortcoming of existing electronic whiteboard change image parameter inconvenience, this use is novel to provide a kind of hand gear of regulating the handwriting input graphic parameter, it includes a digital signal generator and micro controller system, described digital signal generator is a manual digital signal generator, includes a data output terminal; The adjustment structure of manual digital signal generator is installed on the surface of hand gear; Described data output end is connected with the I/O interface of the micro controller system of described hand gear inside.
Further, the adjustment structure of described manual signal generator is knob or slide block.
Further, described manual signal generator is made of potentiometer and A/D transducer, the variable current potential output terminal of described potentiometer is connected with the input end of A/D transducer, the output terminal of described A/D transducer promptly is the data output end of described regulating device, is connected with the I/O interface of the micro controller system of described handwriting input device by data line.
Further, the output port of described A/D transducer is a serial ports.
Further, the variable current potential output terminal of described potentiometer and the input end of A/D transducer mutually between, also be connected with a signal amplifier or impact damper.
Further, the described manual digital signal generator toggle switch that is a binary data output; The output terminal of described toggle switch is the data output end of described regulating device, is connected with the I/O interface of the micro controller system of described handwriting input device by data line.
Further, at the data output end of described manual signal generator, also be connected with a data converter of incorporating into/going here and there out; The serial output terminal of described data converter is the data output end of described regulating device, is connected by the I/O interface of data line with the micro controller system of described handwriting input device inside.
This image parameter manual regulating device that is applied on the electronic whiteboard is simple in structure, be easy to make, only need the adjusting knob of manual rotating electron blank outside, perhaps operate push-and-pull or button, just can realize the effect of change image parameter, bring very large facility for the user of electronic whiteboard.
