Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, there is shown a configuration of a separate remote controller according to the present invention.

Separate remote control 100 of the present invention is divided into two parts, as shown in the upper portion of the simple function remote control 30 configured to provide a signal for sequentially selecting a specific mode of the VCR according to the present invention, and shown in the lower portion As described, it includes a full-function remote control 60 having a general remote control key configuration.

Simple function The remote control unit 30 is a microcomputer that is a control means of a remote control having a plurality of scan signal output terminals S1 to Sn for outputting scan signals and a plurality of key signal input terminals K1 to K4 for receiving key signal inputs. (10), a first key matrix (15) having a mode converter (B1) and all selection keys (B2), a scan signal generator (20) for selectively providing a scan signal to the key matrix (15), A remote control transmitter (5) and a power source (7), wherein the full-function remote control unit (60) has a second key matrix (65) having a plurality of operation keys for generating key code signals related to the operation of the VCR, like a typical remote control unit. ) And ground configuration (13). These two remote control units 30 and 60 are connected to the ground 63 and the second matrix 65 by the power supply 7 and the first matrix 15, respectively, by a connector (not shown) as a connecting means. It is composed.

As is well known, the microcomputer 10, which is a control means of the remote control, has first and second keys configured in matrix form for scanning signals of different pulses through terminals S1 to Sn as shown in the second window side. The output is continued to the matrixes 15 and 65, and a predetermined voltage V _DD (not shown) is applied to each of the key input terminals K1, K2, K3, and K4. If any one key is pressed on the key matrix, the low section of the scanning pulse is input to the key input terminal of the remote controller micom 10 by the connection between the scan line and the key input line, and the microcomputer 10 indicates that the key has been pressed. Will be detected. Similarly, the microcomputer 10 detects each time the mode conversion key B1 and all the selection keys B2 of the simple function remote controller 30 are pressed to generate a certain key code, respectively.

When the two remote controllers 30 and 60 are combined, the microcomputer 10 outputs a key code signal corresponding to the operation of each key of the key matrix 65, and the mode conversion of the key matrix 15 and The keys of the selection keys B1 and B2 are also configured to select any operation mode as described below.

Referring to FIG. 3, a remote control receiver for processing the key signal of the remote control apparatus 100 shown in FIG.

The signal output from the remote control transmitter 5 is received by the receiver 25. The receiver 25 demodulates the signal, removes the carrier component, and delivers the signal to the timer micom 50. The timer microcomputer 50 determines the operation mode of the VCR from the signal and transmits the mode data to the scissor microcomputer 45 to perform the mode.

Timer micom 50 according to the present invention is a predetermined number of operations each time a key code signal generated by the repetitive operation of the mode conversion key (B1) in the simple function remote control 30 is input through the receiver 25 Performs the function of displaying modes sequentially. For this function, the timer microcomputer 50 outputs a control signal to the display control unit 40 of the OSD or the fluorescent display tube. These modes of operation specify one operation of the VCR with a single key operation, such as PLAY, REC, STOP, FF, Fast Forward, REW, PAUSE, etc. These modes may be sequentially developed each time the mode conversion key B1 is pressed on the OSD screen or the fluorescent display tube. Simple Function When the mode selection key B2 of the remote controller 30 is pressed, the microcomputer 50 outputs a signal to the scissor microcomputer 45 to be operated in the currently displayed mode. In order to distinguish the operation mode indication to be selected by the operation of the mode selection key from the operation mode indication currently being executed, an identification mark such as a question mark symbol (?) May be displayed together with the operation mode to be selected.

Referring back to FIG. 1, the scan signal generator 20 includes two NAND gates 3 and 4, and the microcomputer 10 is connected to one input terminal of each of the NAND gates 3 and 4. Scan lines extending from at least two scan signal output terminals S1 and S2 are respectively connected, and a line of the power supply 7 is connected to the buffer 1 through a resistor R at each other input terminal. Each is connected via the inverter 2. The output of the scan signal generator 20 extends to the key matrix 15.

When the simple remote controller 30 and the full-function remote controller 60 are separated from each other, the NAND gate 3 of the scan signal generator 20 passes through the buffer 1 from the power source 7 to the high level signal and the microcomputer ( A predetermined scan pulse is received from the terminal S1 of 10). At this time, the output of the NAND gate 3 changes according to the scan pulse. In addition, the NAND gate 4 receives a low level signal and a predetermined scan pulse from the terminal S2 of the microcomputer 10 through the inverter 2 from the power supply. At this time, the output of the NAND gate 4 outputs a high level signal regardless of the scan signal from the terminal S2. Therefore, the output of the scan signal generator 15 depends on the input signal from the terminal S1.

On the contrary, when the simple function remote controller 30 and the full-function remote controller 60 are assembled, the power supply 7 is connected to the ground 63 of the full-function remote controller 60 so that the NAND of the scan signal generation unit 20 can be used. The outputs of the gates 3 and 4 are provided in reverse to the above. Therefore, at this time, the output of the scan signal generator 20 depends on the output signal of the terminal S2 of the microcomputer 10.

As a result, when the microcomputer 10 receives a key input signal indicating that the key B1 or B2 is pressed by the scanning signal from the terminal S1, the key code according to the key operation of the simple function remote controller 30 is received. A signal is generated, and when it is detected that the key B1 or B2 is pressed by the scanning signal from (S2), the key code signal according to the operation of any operation key belonging to a part of the key matrix of the full-function remote controller 60 Will occur.

The signal generated in the key matrix 65 of the full-function remote controller 60 will be processed in a conventional manner in the receiving system shown in FIG. 2, and the signal generated in the key matrix 15 of the simple function remote controller 30. Will be described with reference to the flowchart of FIG.

Simple function The microcomputer 10 which detects that the key operation of the remote controller 30 is caused by the scanning line S1 transmits the key code signal of the mode conversion key B1 or the mode selection key B2 through the transmitter 5 through the VCR. Transfer to the receiver 25 of the main body.

The timer microcomputer 50 of the remote control signal processing apparatus determines that the key code is generated by the simple function remote controller 30 and performs the simple function mode.

In step P1, it is determined whether the signal is generated from the mode conversion key B1, and each time the conversion key B1 is pressed, the next operation mode is displayed on the fluorescent display tube or the OSD screen in the preset order in step P2.

In step P3, it is determined whether the signal is generated from the mode selection key B2, and the operation mode currently displayed in step P4 is performed.

Providing the signal for executing the current mode selected by the mode selection key B2 to the scissor micom 45, or when the selection key B2 is not activated in step P3 and another key is pressed in step P5; The simple function mode is released as in.

As described above, the present invention makes it possible to conveniently operate the VCR with a simple function remote control when selecting only the one-time operation mode in a single control configuration, and full-function when many operations related to other one-time operation are required. The advantage of operating the VCR by combining the remote control is provided.
