The process 400 is performed.

The third process 300 is a process of outputting a remote control signal according to an input from a key matrix unit 310 after inputting a remote control button during the call (step 200), and after the remote control output the remote control button is turned off. If it is determined to be off, it is performed to include the process 320 for guiding the fourth process 400 to be performed.

A process of inputting a button (410), a process of outputting a phone driving output accordingly to perform a phone function (420), and a process of checking whether the telephone off button is pressed in this state (430). .

When the telephone off button is input in the fourth process 400 (operation 430), the process returns to the remote control mode (440).

Hereinafter, the operation of the present invention will be described together with the circuit diagram of FIG. 3 and the prochart of FIG. 4. The remote control function of the key matrix unit 11, the pull-down resistor unit 20-2, the microcomputer 20-1, the oscillator 20-3, and the remote controller output unit 3 of the composite key matrix unit 10 is conventional. Since it is the same as the description thereof will be omitted. While performing the remote control mode by operating the conventional key matrix unit 11 according to the present invention, when the telephone on-off button 12 is turned on, the composite control unit 20 recognizes this (step 100), and thus the telephone on-off When the button 12 is turned on, the microcomputer 20-1 performs a second process 200 for checking whether the remote controller button 13 is pressed during a call. Subsequently, the microcomputer 20-1 performs the third process 300 according to the input of the key matrix unit 11. When the remote control button 13 is turned on during the call in the second process 200, the remote control function is performed through the remote controller output unit 3 according to the input of the key matrix unit 11 (step 310). Specifically, when the on-off button 12 is on but the remote control button 13 is activated during the call (step 200), the high level is increased by the output terminal B4 of the remote control button 13 during the call. Is applied to one input, and the high level signal through the output terminal B2 of the telephone on-off button 12 is inverted in the inverter 43 and applied to the other input terminal of the ore gate 44 at the low level, but the or gate 44 The high level is applied to one input terminal of the first and gate 45 because the high level is outputted even if one level is input. In this state, when the remote control operation signal through the key matrix unit 11 is applied to the other input terminal of the first AND gate 45 through the microcomputer 20-1, the first gate together with the output of the ore gate 44 (high level) is displayed. Multiply by the AND gate 45 to drive the remote control output unit (3). As a result, the remote control can perform its original function even when the phone button is pressed. Subsequently, the process 310 is performed until the remote controller button 13 is turned off (before the output terminal B4 is turned low and the output terminal B3 is turned high) during a call. 4 to perform step 400 (step 320). That is, when the remote control button 13 is turned off during a call, a low level signal is applied to an input terminal of the or gate 44 through the output terminal B4. The output of the level is applied to the first AND gate 45 to block the output of the remote controller output unit 3. In this way, the remote control button 13 is turned off during the call (steps 200 and 320), and when the key input of the key matrix unit 11 of the phone function is input, this is checked (step 410) and the phone outputs. Process 420). Specifically, in this case, when the on button is turned on from the telephone on-off button 12, the high level is applied to the second end gate 47 through the output terminal B1. Of course, the remote control button 13 during the call is applied to the low level through the output terminal (B3). Then, the inverter 46 is inverted to a high level and applied to the other input terminal of the second and gate. Therefore, the second AND gate is applied to one input of the third AND gate 48 at a high level. In addition, the microcomputer 20-1 drives the telephone output unit 7 of the output unit 30 to enable data transmission and transmission and reception of the telephone number through the output terminal I. When the phone on-off button 12 is turned off while using the telephone (step 430), the normal remote control mode is performed (step 440). At this time, the output process 420 for driving the phone uses the phone gate 42, as described above. When the telephone on-off button 12 is operated as an off button, the output terminals B1 and B2 are at a low level so that the telephone gate 42 is turned off, but the remote controller gate 41 is at a high level in the inverter 43. Is inverted to the OR gate 44 to operate to output a high level to one input terminal of the first AND gate 45, and thus the remote controller mode signal of the microcomputer 20-1 at the first AND gate 45. To output to the remote controller output unit (3). At this time, if the remote control button 13 is turned on during the call, the output B4 becomes a high level to drive the remote control gate part 41, and when turned off, the output B3 is inverted from the inverter 46 to a low level and the second By being applied to the AND gate 47, the gate parts 41 and 42 can be selectively used according to the operation of the remote control button 13 during a call.

In the process (100) has been described as performing a process (200) to check only whether the phone on off button 12 is simply on and then check whether the remote control button 13 is on during the call, another example of the present invention As shown in FIG. 5, if it is confirmed that the telephone on-off button 12 is operated as shown in FIG. 5, it may be performed to directly perform a telephone function as in steps 410 and 420 (step 100 ′). Of course, the process of performing the telephone function at this time will be understood to be the same as the process (410,420). Eventually, it is possible to perform a phone call function when the phone on off button is turned on during the remote control mode, and when the remote control button 13 is turned on during the call function (step 200), the remote control button 13 during the call is performed. The remote control function can be performed until () is off (step 300), and if the remote control button 13 is turned off during a call, the phone function can be continued (step 400). In another embodiment of the present invention, when the telephone function is performed in the process 100 ′, when the remote control button 13 is turned on during the call in the process 200, the process 300 is then performed. The process 100 is repeated. Of course, in the microcomputer 20-1, an algorithm for performing this process should be embedded.

As described above, the present invention adds a telephone on / off button and a remote controller button during a call to the key matrix unit. The remote control function and the phone function can be selected and used, so there is no need to purchase two separately, and the phone can be operated by operating the telephone on / off button while performing the remote control unique function. In addition, since the gate part is configured to perform the remote control function while maintaining the phone function while the phone function is being performed, the phone and the remote control functions can be conveniently used simultaneously or selectively.
