That is, FIG. 4 shows the configuration of the pad remote controller 70 of the remote control transmitting / receiving system having the keypad input unit according to the present invention.

A plurality of pad touch portions 72 are arranged in a grid pattern on the rectangular main body 71 and remote control transmission data corresponding to the contact of the pad touch portion 72 with the human body is provided on one side of the main body 71 And an optical transmitter 73 for transmitting the optical signal.

The pad switch portion 74 corresponding to the pad touch portions 72 of the main body 71 has been described in more detail with reference to FIG. 5A.

In this embodiment, the transistors Tl and Tr2, the charging resistor R, the charge / discharge capacitor C, and the logic output 0 are connected to the touch plate TP as inputs.

Although the pad switch unit 74 includes the CMOS transistors and the touch plate, the pad switch unit 74 may be replaced with a thermal sensing switching circuit or the like.

The system microcomputer 2 of FIG. 3 receiving the remote control command with respect to the pad remote controller 70 is equipped with the pad input processing program 100 as shown in FIG.

If the user touches the pad touch part of the pad remote controller to check whether there is a received key input, the system stores the value first and then calls up the OSD menu screen. Checking whether the same pad touch part has been pressed again after confirming the command display corresponding to the pressed pad touch part, comparing the already stored primary value with the present value, and executing the contents of the command if they match.

That is, it is checked whether or not there is key input reception in the system (step 101). If YES, the system stores the current key data value B (step 102) (Step 103).

If the OSD menu screen has been output in step 103, it is checked whether or not the input of the pad touch part 72 is again made by the user (step 104). If there is no OSD menu screen output in step 103, (Step 109).

If YES in step 109, the OSD menu screen is output (step 110). If the pad touch part 72 is input in step 104, the key data value A currently input is stored (step 105).

The system then compares the current key data value A with the already stored key data value B (step 106). If they are the same, the selected command is executed (step 107). Otherwise, the system outputs the OSD menu screen (step 113) The later input value A is displayed as "B" (step 108).

When the arbitrary second m seconds have elapsed in step 109, the OSD 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 a key input using the pad touch unit 72 of the pad remote controller 70, the user inputs a finger to the pad touch unit 72 corresponding to the command, The microcomputer of the pad remote controller 70 recognizes this and provides a transmission signal to the remote controller optical transmitter 73. [

The transmission signal is input to the system remote control receiver of the remote control receiver side and then transmitted to the microcomputer 2. The microcomputer 2 recognizes the transmission signal, And outputs the SD menu screen through the OSD unit 11.

At this time, the OSD 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 Record 1 2 3 4 5 6 7 8 9 0

Therefore, when the user touches the pad touch part 72 which has been contacted again after checking and checking the cursor, the corresponding command is executed because the cursor is located at a position corresponding to the pad touch part 72 that the user touches.

When the user touches the touch plate TP as shown in FIG. 5, the pad switching unit 74, which is operated by the contact of the pad touch unit 72, touches the touch plate TP, The transistors Tr1 and Tr2 are alternately turned on / off, but the conduc- tor C is rapidly charged through the resistor R and performs the operation as shown in Fig. 5b so that the final output O provides an output of logic 0 .

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

The microcomputer 2, such as the Vishal system, performs the above-described operation together with the pad input processing program 100 shown in FIG. 6, which checks whether there is key input reception in the system, (Step 101 to step 103). If the OSD menu screen related to the input of the pad touch part 72 is output,

If the OSD menu screen has been output, it is checked whether or not the input of the pad touch unit 72 is again performed. If there is no OSD menu screen output, a check is made as to whether elapsed seconds have elapsed (steps 104 and 109).

If the pad touch unit 72 is input, the currently input key data value A is stored (steps 105 and 110).

The system compares the current key data value A with the already stored key data value B, and if it is the same, it executes the selected command, otherwise, it outputs the OSD menu screen and again inputs the input value A as B (Steps 106 to 108, 113).

When a certain second (m) has elapsed, the OSD menu output is turned off and the key input data B value is stored (steps 111 and 112).

Since the key input mode of the remote control transmitter used in the electronic device having the OS function can be realized by the human-touch-type keypad, the present invention has a good durability of the set and can simplify the configuration. On the other hand, And can accommodate many key switch configurations relatively unrestricted in performance.
