In the above system, when the button key is pressed through the remote control transmitter 13, the microcomputer 2 generates the OSD menu screen through the OSD circuit 11, which is screen-interactive through the TV receiver 10. It was to perform a function setting operation.

In such a conventional system, since the key input means of the remote controller transmitter 13 is switched through a mechanical structure of a button touch type, there is a high probability of malfunction due to mechanical wear such as a button part when the remote controller transmitter is used for a long time. .

In addition, the key input means of the button touch remote control transmitter 13 as described above is difficult to avoid the troublesome and cumbersome production of such a set because it has to mechanically produce dozens of button number position structure.

In addition, the number of switches of the key input means of the remote control transmitter as described above has a limited volume and the number of switches that can be accommodated on the plane is limited in this remote control transmitter design.

An object of the present invention is to configure the key input means of the remote control transmitter used in the TV receiver or VSI system having an OSD function to the human contact keypad input means to improve such a conventional problem, By using the OS function to check the pressing of the system to facilitate the use of this system.

That is, Figure 4 shows the configuration of the pad remote control 70 of the remote control transmission / reception system having a keypad input means according to the present invention.

Here, the rectangular main body 71 is provided with a plurality of pad touch units 72 arranged in a lattice shape. On one side of the main body 71, remote control transmission data corresponding to the pad touch unit 72 coming into contact with the human body is provided. An optical transmitter 73 is provided for transmitting.

In addition, the pad switch portion 74 corresponding to the pad touch portions 72 of the main body 71 shows an example of this in more detail as shown in FIG. 5A.

Here, the transistors include the CMOS transistors Tr1 and Tr2, the charging resistors R and the charge / discharge capacitors C, and the transistor circuits that drive the logic output 0 through the touch plate TP.

The pad switch unit 74 shows that this is composed of CMOS transistors and a touch plate, but it can be replaced by a thermal sensing switching circuit.

In addition, a pad input processing program 100 as shown in FIG. 6 is mounted in the system microcomputer 2 of FIG. 3 that receives a remote control command in association with the pad remote controller 70.

If the system checks whether there is a key input received by touching the pad touch unit of the pad remote control, the system stores the value first and calls up the OS menu screen. After confirming the command display corresponding to the pressed pad touch unit, it is checked whether the same pad touch unit is pressed again, and compares the stored primary value with the current value and executes the command contents if they match.

That is, the system checks whether there is a key input reception in the system (step 101), stores it as the currently input key data value B (step 102), and outputs the OS menu screen related to the input of the pad touch unit 72 again. It is checked whether or not it is (Step 103).

If the OSD menu screen is output in step 103, it is checked whether the input of the user's pad touch unit 72 is made again (step 104). In step 103, it is checked whether m seconds have elapsed when there is no output of the OSD menu screen. (Step 109).

In step 109, the OSD menu screen is output within m seconds (step 110). If the pad touch unit 72 is input in step 104, the key data value A currently stored is stored (step 105).

The system again compares the current key data value A with the key data value B already stored (step 106), and if they are the same, performs the selected command (step 107), otherwise outputs the OSD menu screen (step 113), and again. The later input value A displays an OSD prompt to input B (step 108).

When the m seconds of the arbitrary seconds have elapsed in step 109, the ODS menu output is turned off (step 111), and the key input data B value is stored (step 112).

3 to 5, when the user performs key input using the pad touch unit 72 of the pad remote controller 70, the user touches the pad touch unit 72 corresponding to the corresponding command. When contacting the microcomputer of the pad remote control 70 recognizes this and provides the transmission signal to the remote control optical transmitter 73.

The transmission signal is inputted to the system remote control receiver of the remote control receiver and then transmitted to the microcomputer 2. The microcomputer 2 recognizes this and then corresponds to the arrangement of the pad touches 72 of the pad remote controller 70. Outputs the SD menu screen through the OS.

At this time, the OS menu screen can be configured as follows.

Pad Input OSD Menu Screen ▼ TV Power Video Power TV / Video Sound Size ◁ ▷ Channel ▷ ▷ Rewind Play Fast Forward Stop Pause Recording 1 2 3 4 5 6 7 8 9 0

Therefore, since the user has a cursor ▼ at a position corresponding to the pad touch unit 72 that the user touches, when the user presses the pad touch unit 72 that has been contacted and checked again, the corresponding command is executed.

In addition, when the user touches the hand with the touch plate TP as shown in FIG. 5, the pad switching unit 74 that switches by the pad touch unit 72 contacts the hum voltage induced. Transistors Tr1 and Tr2 are alternately turned on and off, but the capacitor C is rapidly charged through the resistor R, and as shown in FIG. 5B, the final output O provides the output of logic 0. Will be.

Therefore, the microcomputer on the remote control transmitter side recognizes this and outputs the corresponding transmission signal to the optical transmitter 73.

On the other hand, the above operation is performed by the microcomputer 2 such as the VSI system together with the pad input processing program 100 as shown in FIG. 6, which checks whether there is a key input reception in the system, The stored key data value B is stored, and it is checked again whether the OS menu screen related to the input of the pad touch unit 72 is output (steps 101 to 103).

If the OSD menu screen is output in step S, it is checked whether the user inputs the pad touch unit 72 again, and if there is no output of the OSD menu screen in step S, it is checked whether m seconds have elapsed (step 104,109).

The OS menu screen is displayed within m seconds in the above, and when the pad touch unit 72 is input, the currently input key data value A is stored (steps 105 and 110).

Again, the system compares the current key data value A with the already stored key data value B, and if they are the same, executes the selected command, otherwise displays the OSD menu screen, and again displays the OS input to enter B as a later input value. (Steps 106 to 108,113).

In addition, when the random second m seconds has elapsed, the ODS menu output is turned off, and the key input data B value is stored (steps 111 and 112).

In the present invention, since the key input form of the remote control transmitter used in the electronic device having the OSD function can be made by the keypad of the human body, the durability of this set is good and the configuration can be simplified, and on the other hand, various commands Many key switch configurations for performance can be accommodated relatively without limitation.
