Description

Multiple Key Processing Control Method of Control Key Panel for Electronic Devices

The present invention relates to a multi-key processing control method of a control key panel for an electronic device, and more particularly, to a control device in a control key panel (Control Key Panel) equipped with a plurality of function keys employed for the function control of the electronic device. The present invention relates to a multi-key processing control method for a control key panel for an electronic device, in which an operation of an execution key input for a plurality of functions to be applied can be achieved by a quick and easy multiple key input only with a simple function key configuration.

As is well known, in various electronic apparatuses including video reproducing apparatuses such as televisions and video tape recorders, which are generally used, matrix buttons are provided on the front control panel of each apparatus for button input of commands for overall functional operation. Separately, for the convenience of the user, by generating and generating a function control signal for command of a function operation in the form of wireless data, a remote controller is adopted as a remote control device capable of controlling the function at a long distance.

According to the remote control used for remote function control of such an electronic device, a function key provided on a keypad having a matrix form installed on the front of the remote control is keyed for a predetermined function command and the key input state is recognized according to a decoding operation. The remote code data corresponding to the key input is read from the pre-stored remote code data, that is, code data matched with code control data for code recognition stored in the data storage means in the electronic device. It is generated in the form of a remote signal such as a signal or an ultrasonic signal and transmitted to the corresponding electronic device.

At this time, the main body side of the electronic device receives the remote signal through a remote signal receiver such as an infrared receiver or an ultrasonic receiver installed in a predetermined front part thereof, and then restores the signal through a signal correction and decoding operation. On the other hand, as a result of receiving the restored function control signal through the input port, the code control data stored in the data storage means is read and compared / computed by the code control data according to the address corresponding to the function command from the remote controller. Next, the control function is performed according to the result to enable the corresponding function operation to enable the function execution.

Here, in the signal form of the remote function control signal generated by such a remote control, it is composed of data pulses having a predetermined code value. For such data pulses, the head pulse data and the head pulse data informing the input of the function control signal are described. Consists of custom pulse data unique to each manufacturer and control pulse data having data codes for function control, interposed between the custom pulse data and the function control pulse data. Data for separating and classifying both data is further provided to transmit, for example, a wireless transmission time unit of about 50 mSec.

In addition, among such electronic devices, for example, a television receives remote function control pulse data transmitted according to a key input of the remote controller, and the main power on / off operation or channel switching or volume control or on / off corresponding to the function control is received. Various functional operations, such as the off-timer reservation setting operation, can be implemented to allow free execution of all functional operations at a long distance.

However, in the case of a control key panel which is adopted in front of such a plurality of electronic devices and installed in front of the plurality of electronic devices, a plurality of function keys are used for the multi-function execution operation according to the diversification trend of the functions applied to the electronic devices that are the targets of the corresponding function control. In this case, there is an inconvenience that the complexity or difficulty of key manipulation for the user is increased.

In addition, in order to reduce the number of multiple function keys installed in the corresponding control key panel, a separate mode key can be installed so that double function key input can be performed even by operating the same function key according to the operation state of the mode key. The present invention has also been adopted, but disadvantages arise in that the user must confirm in advance the mode state set by the operation of the separately installed mode key.

Accordingly, the present invention has been made in view of the above circumstances, and the double key of the function key is provided by a flashing operation of the light emitting means for providing a control key as a special key on the control key panel of the electronic device and informing the key operation state of the shift key. An object of the present invention is to provide a multi-key processing control method for a control key panel for an electronic device, which can be easily and quickly made.

According to the multiple key processing control method of the control key panel for an electronic device according to the present invention to achieve the above object, in the control key panel for performing a function control by the execution key input for a plurality of functions applied to the electronic device And a first step of setting a dual key mode by operating a shift key of the control key panel, a second step of lighting an LED indicating a setting state of the double key mode, and a first and second function for each key. A third step in which a predetermined function key is keyed among a plurality of function keys capable of double function key input, and a function control signal of a second function according to the dual key mode corresponding to the function key being operated; A multi-key processing control method for a control key panel for an electronic device, comprising a fourth step of outputting to the processing means and turning off the lit LED.

According to the present invention configured as described above, the dual key mode is set according to the state of operating the shift key installed separately from the remote control for the function for the function applied to electronic devices such as a television or video tape recorder mode so that the LED is turned on It is possible to confirm the execution status of the function key and to enable the function key input under the dual key mode according to the key operation of the function key to which the dual function is assigned.
