Abstract
Using technique for locking data line or technique for pausing keyboard, the invention makes user on his own initiative possible to cut off operation rapidly through hardware technique. The invention sets up electronic trigger (or similar device and functions) possessing function of locking mechanical position on keyboard to control on/off of communication line between keyboard and host. The invention also can setup a key button to control keyboard chip entering into pause state so as to control on/off of communication line between keyboard and host indirectly.
Description
Technical field the present invention relates to the application of electronic switching technology on keyboard input devices.
The background technology keyboard is a kind of main electronic equipment by switching technique work.In the unusual busy modern society of information processing, people require also more and more high for space utilization efficient.The keyboard sensitivity that occupies office visual field main space is more and more high, has touching will import some characters slightly, thus people can only careful attention this bring convenient and partner efficient.The present invention solves at the anti-error touching switch of increase on the common keyboard and chats problem.
Summary of the invention the present invention uses data line lock-in techniques or keyboard time-out technology, makes the user pass through the initiatively work of fast shut-off keyboard of hardware technology under the situation that can expect, reaches the protection main frame and can not receive the purpose of error message.Use this technical user can also when needed keyboard be utilized into a reading frame that certain angle of inclination is arranged.
Embodiment the present invention is provided with the electronic switch with mechanical location lock function or has the electronic circuit switch of similar functions (as for avoiding signal peaks to use photoelectric control circuit) on keyboard, directly the communication line break-make between supervisory keyboard and the main frame.
The present invention also can enter halted state with the supervisory keyboard chip by button is set, indirectly the communication break-make between supervisory keyboard and the main frame.
Electronic switch that the present invention relates to or electronic circuit switch are for not providing on the data line that the interface (as conventional keyboard interface and other) of keyboard chip initiation can be connected signal cable to avoid unnecessary equipment risk and equipment work parameter change by charged plug.
Electronic switch that the present invention relates to or electronic circuit switch can provide the interface (as USB interface and other) of keyboard chip initiation by charged plug for some, except aforementioned schemes, also can be connected on the power lead of linking up the signal cable between main frame and the keyboard.
The mechanical motion space that the present invention relates to the switch manual control part generally can present visibly different mode of operation to the mechanical motion space of common key-press on this corresponding keyboard, as uses three-dimensional different dimensions.
Claims (6)
1. the present invention is the keyboard input devices with anti-error touching function.It is characterized in that using the communication line break-make between direct or indirect supervisory keyboard of electronic technology and the main frame.
2. the electronic technology of feature 1 indication can be the electronic signal switch with mechanical location lock function that is connected on keyboard and the host communication cable, or the electronic circuit switch of similar functions is arranged.
3. the electronic technology of feature 1 indication can also be the keyswitch that the supervisory keyboard chip enters halted state.
4. the electronic signal change-over switch of feature 2 indications or electronic circuit switch are for not providing on the data line that the interface (as conventional keyboard interface and other) of keyboard chip initiation can be connected signal cable to avoid unnecessary equipment risk and equipment work parameter change by charged plug.
5. the electronic signal change-over switch of feature 2 indications or electronic circuit switch can provide the interface (interface of this function being arranged as USB interface or other) of keyboard chip initiation also can be connected on the power lead of signal cable by charged plug for some.
6. feature 3,4, and the mechanical motion space of common key-press generally can present visibly different mode of operation on the mechanical motion spatial contrast corresponding keyboard of its manual control part of switch of 5 indications, as uses three-dimensional different dimensions.
