[Technical Background of the Invention and Problems Thereof] Conventionally, there has been a remote control device having a learning function of this type having a configuration shown in FIG. In the figure, 1 is a receiving unit for receiving a remote control signal I to be learned transmitted from an arbitrary remote control device, and 2 is a storage unit 4 for storing a remote control signal or a learned signal programmed in advance in an arithmetic processing unit 6. The operation key 3 is a mode switch for switching between reception and transmission operations. Reference numeral 4 denotes a storage unit for storing signal elements, and reference numeral 5 denotes a signal which is analyzed and compared by the reception unit 1, stores the signal elements in the storage unit 4, and retrieves the signal by calling up the signal elements from the storage unit 4. This is the control unit to be reconfigured. 6 is an arithmetic processing unit having the control unit 5 described above, 7 is a display unit for displaying an operation sequence in the remote control device, 8

4 to ₇ , the on-period and the off-period are made different from each other, so that each duty ratio has a different signal form. The storage unit 4 described above, as shown in FIG. 6, it is constituted by a parameter storage unit 4 ₁ and the signal configuration storage section 4 _2. Then, the parameter storage unit 4 ₁ signal elements of the remote control signal I in the form shown in FIG. 5 is stored, the signal configuration storage section 4 ₂ configuration of the remote control signal I is stored. The above-described signal configuration storage section 4 ₂
In actually addresses of each element stored in the parameter memory 4 ₁ is stored. Next, the operation of the remote control device having the above configuration will be described. When the reception mode is set by operating the mode changeover switch 3, the arithmetic processing unit 6 enters the reception state. Then, a remote control signal I (for example, an infrared signal) to be learned transmitted from another remote control device is
The signal is detected by the receiving unit 1 and converted into an electric signal.

Next, after the mode switch 3 is switched to set the transmission mode, when a predetermined key of the operation mode 2 in which the learning is performed is operated, a signal element corresponding to the predetermined key is stored in the storage unit 4 (the parameter storage unit 4). ₁ and the signal configuration storage unit 4 ₂ ) are called up based on the control of the control unit 5, and the signal learned as described above is configured and supplied to the transmission unit 8. The transmission unit 8 converts the signal reconstructed by the control unit 5 into infrared light or the like, sends the signal as a transmission signal, and controls the operation of a device to be controlled. In addition,
The above procedure is displayed on the display unit 7 based on the control of the control unit 5. Since the conventional remote control device having the learning function is configured as described above, a large storage capacity is required for the storage unit in order to store the signal configuration and each parameter. Therefore, there is a problem that the remote control device having the learning function is economically expensive and requires a large mounting area for the storage unit, which is not practically preferable. [Purpose of the Invention] The present invention has been made in order to eliminate the above-mentioned problems in the related art, and has a call-only storage unit, in which a time parameter is stored in advance, and a parameter storage constituting a storage unit is provided. It is an object of the present invention to provide a remote control device capable of greatly reducing the storage capacity of a unit. [Summary of the Invention] The present invention receives a remote control signal transmitted from any remote control device, stores it in a storage unit, and transmits the stored remote control signal to control the operation of a target device. In a remote control device having a learning function to perform, a call-only storage unit that previously stores a reference signal element for determining a signal element constituting the received remote control signal, Discriminating means for analyzing and comparing a remote control signal and discriminating a signal element that does not match or approximates the reference signal element as a mismatch signal element among signal elements constituting the remote control signal. The remote control to learn based on the result of the determination. If all of the signal elements that make up the control signal match or approximate the reference signal element, the signal element is not stored, and some of the signal elements that make up the remote control signal to be learned match the reference signal element. Alternatively, if the approximation cannot be made, the signal configuration and the non-coincidence signal element which does not match or approximate the reference signal element are stored, and all of the signal elements constituting the remote control signal to be learned do not match the reference signal element. Or, if the approximation is not made, all the non-coincidence signal elements are stored, so that it is not necessary to store all the signal elements constituting the remote control signal when learning the remote control signal. To significantly reduce the storage capacity of the storage unit, miniaturize the storage unit and improve the space factor Can be achieved.

In the above-described embodiment, the case of a remote control signal has been described. However, if the data sequence is configured with parameters that can be predicted in advance as a signal form to be learned, the same effect as described above can be expected. Therefore, the storage capacity can be reduced as much as possible. [Effect] According to the present invention described above, a time parameter as a signal element constituting a remote control signal is stored in advance in a call-only storage unit as a reference signal element, and the remote control signal received by the determination unit is analyzed and analyzed.
By comparing and discriminating signal elements that do not match or approximate the reference signal element among the signal elements constituting the remote control signal as mismatch signal elements, all the signal elements are stored in the storage unit during learning. Therefore, the storage capacity of the storage unit for storing the signal elements can be significantly reduced, and the storage unit can be downsized to further improve the space factor.
