Can be remotely controlled together. [Embodiment of the Invention] Hereinafter, an embodiment of a remote control device with a learning function according to the present invention will be described with reference to FIGS. In FIG. 2, reference numeral 1 denotes a microcomputer (CPU) that operates according to a predetermined control program as shown in a flowchart described later, and the CPU 1 has a read-only memory (ROM) 1a as a first storage means, It has a timer 1b, a register A1c, a register B1d, and the like. 2
Reference numeral 3 denotes a random access memory (RAM) as a receiving unit for receiving a remote control signal from another remote controller (not shown), and 2 denotes a random access memory (RAM) as a second storage unit in which information is written and read by the CPU 1. A transmitting section as a transmitting means for transmitting a remote control signal formed based on the output information, a mode switching switch as a mode switching means for switching the operation mode of the remote control between reception and transmission, and a display of an operation sequence of the remote control A display unit 7 is an operation unit having a plurality of operation keys. The operation keys of the operation unit 7 include, for example, a VTRPLAY key, and a storage unit corresponding to each operation key is prepared in the ROM 1 a and the RAM 3. For example, the storage unit of the ROM 1a corresponding to the VTR PLAY key is divided into first and second storage blocks 1a-1 and 1a-2 as shown in FIG. 3A, and the first storage block 1a For example, PLAY code information for generating a remote control signal for starting reproduction of a VTR sold separately by a company A, which sells a remote controller together with a system controller, is stored as the first information in the second storage block 1a-2.
Stores, as second information, function code information for generating a remote control signal for switching the function of the amplifier of the system controller to VTR-AUX. Nothing is stored in the storage section of RAM3 at first,
When the mode changeover switch 5 is switched to reception and a remote controller signal from another remote controller is received by the receiver 2, the information of the received remote controller signal is displayed in FIG. It can be stored as the information of FIG. 3 as shown. Therefore, a remote control signal generated by operating the PLAY key of the remote control of the VTR manufactured by Company B is received, and the information of the remote control signal is stored as the third information in the corresponding storage unit in the RAM 3 by operating the VTR PLAY key. Can learn. When the mode switch 5 is on the transmitting side, the operation unit 7
When the VTR PLAY key is operated, before learning, the first and second information are read from the storage unit in the ROM 1a corresponding to the key, and a remote control signal based on this information is transmitted. If it is made by a company, playback start of the VTR and function switching can be performed by a single key operation. On the other hand, after the learning as described above, when the VTR PLAY key is operated, as shown in FIG. 3 (c), the correspondence in the RAM 3 is changed to the third information from the storage unit and the corresponding information in the corresponding storage unit in the ROM 1a. The second information is read out from the second block 1a-2, and a remote control signal based on this information is transmitted, and the reproduction of the VTR made by the B company is started by a single key operation, and the VTR made by the A company is started. The function of the amplifier can be switched to VTR. The operation performed by the CPU 1 for the operation of the remote controller described above will be described in detail with reference to the flowchart of FIG. The flowchart starts when the power of the remote controller is turned on. In the first step S1, it is determined whether or not the mode switch 5 is on the receiving side. If the mode changeover switch 5 is on the receiving side and the determination is YES, step S
The process proceeds to step 2, where the first message information stored in, for example, the ROM 1a is read out and output to the display unit 6 to make a display prompting the user to perform key information of another remote controller. Thereafter, the process proceeds to step S3, where it is determined whether or not a remote control signal from another remote control has been input within a predetermined time by monitoring the output of the receiving unit 2 for a predetermined time by the timer 1b. If no other remote control is operated within a certain time and no remote control signal is input,
The determination in step S3 is NO, and the process returns to step 1. However, if there is an input within a predetermined time and the determination is YES,
Proceed to step S4. In step S4, the received remote control signal is analyzed and the information is stored in the register A1c. After storing the information in the register A1c, the process proceeds to step S5, where the second message information stored in, for example, the ROM 1a is read out, output to the display unit 6, and a display prompting the user to re-operate the same operation key is performed. Let Thereafter, the process proceeds to step S6, where it is determined whether or not a remote control signal has been input within a predetermined time, as in step S3. If the determination is NO, the process returns to step S1, and if YES, the process proceeds to step S7. In step S7, the received remote control signal is analyzed and the information is stored in the register B1d.
Subsequently, the process proceeds to step S8, where the information stored in the register A1c is compared with the information stored in the register B1d, and as a result, it is determined in the next step S9 whether or not the two substantially match. The above steps S5 to S9 are for preventing the information of the erroneously received remote control signal from being learned. If the determination in step S8 is NO, there is an error, and at this time, the process returns to step S2 to repeat the above operation. On the other hand, if the determination is YES, it is determined that the remote control signal has been correctly received, and the process proceeds to the next step S9, where, for example,
Reading the third message information stored in the ROM 1a,
This is output to the display unit 6 to display a message prompting the user to operate the operation key of the operation unit 7 to indicate which operation key the information of the received remote control signal should be stored in the RAM 3. After the output of the third message information, the process proceeds to step S10, where it is determined whether or not the operation key of the operation unit 7 has been turned on within a predetermined time by monitoring the output of the operation unit 7 by the timer 1b. When the determination is NO, the process returns to step S1. When the determination is YES, the process proceeds to step S11, where the information stored in the register A1c or the register B1d in the storage unit in the RAM 3 corresponding to the operated operation key of the operation unit 7 is stored. The data is written and stored, and then the process returns to step S1 to repeat the above operation. When the determination in step S1 is NO, that is, when the mode changeover switch 5 is on the transmitting side, the process proceeds to step S12, where it is determined whether the operation key of the operation unit 7 is turned on. When the determination in step S12 is NO, the process returns to step S1, and when the determination is YES, the process proceeds to step S13, where it is determined whether or not information has been written to the storage unit in RAM 3 corresponding to the operation key operated here. . If the information has been written and the determination is YES, the process proceeds to step S14, where the RAM corresponding to the operation key operated here
3 and the second information of the second storage block 1a-2 of the storage unit of the ROM 1a is read out and transmitted to the transmission unit 4.
To output a remote control signal based on the information. On the other hand, when the information has not been written and the determination is NO, the process proceeds to step S15, where the operation key operated here is replaced with the first and second information stored in the storage unit in the corresponding ROM 1a. The information is read out and output to the transmission unit 4 to transmit a remote control signal based on the information. As is clear from the description given with reference to the flowchart of FIG. 4, when the mode is switched to the reception mode by the mode changeover switch 5, the CPU 1 transmits the information of the remote control signal received from the outside by the reception unit 2 to the operation unit. In addition to the writing means 11 for writing as variable information into the storage unit of the RAM 3 corresponding to the operated operation key 7, the operation of the operation key of the operation unit 7 when the mode is switched to the transmission mode by the mode changeover switch 5 ROM 1a corresponding to the operated operation key
And the variable information stored in the storage unit of the RAM 3 functioning as the reading means 12. In the above-described embodiment, the second information in the specific storage unit of the ROM 1a is one code, but this may be a plurality of codes. A similar thing is
The information stored in the storage unit in the RAM 3 can also be said. In the illustrated embodiment, when the information is written in the corresponding storage unit in the RAM 3, the information in the RAM 3 is read,
Although the first information stored in the first storage block of the storage unit of the ROM 1a is not read, a selection switch for selecting which information to read may be provided. Further, although only one information in the ROM 1a is always read, a switch for selecting the information to be read may be provided. [Effects] As described above, according to the present invention, a single key operation combines pre-stored fixed information with variable information of a remote control signal received and stored from another remote control to control the remote control signal. Can be transmitted, so that even if the functions corresponding to the fixed information and the variable information are of different devices, remote control can be performed with a single key operation without using two key operations. As a result, the operability is improved.
