Abstract

PURPOSE:To attain remote control independently of the number of controlled devices by forming part of a storage circuit with an external storage circuit and adding a mechanism to mount simply the external storage circuit removably to the transmitter. CONSTITUTION:The above transmitter is provided with an optional mechanism to mount the external storage device 8 simply removably, and a controller 2 decodes a remote control signal sent from a reception circuit 5 and converts the signal into a binary code. The binary code is stored in a built-in storage circuit 3 or an external storage device 8 together with a key data of a keyboard 4. When the key of the keyboard 4 is depressed, the same data as the key data of the key is sought from the built-in storage circuit 3 or the external storage device 8 to read the binary code stored together with the key data. Then the controller 2 generates a remote control signal from the binary code and sends it to a transmission circuit 6. Thus, one remote control transmitter 1 controls controlled devices independently of the number.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a learning type remote control transmitter, and more particularly to a memory circuit for storing remote control signals in a learning type remote control transmitter.

[Conventional technology]

Conventional learning type remote control transmitters have a built-in rewritable memory circuit that memorizes remote control signals, write data within the limit that can be written to the memory circuit, and extract predetermined data from the written data by key operation. The remote control signal was restored and transmitted.

[Problem to be solved by the invention]

In the conventional learning type remote control transmitter mentioned above, the capacity of the built-in memory circuit is limited, and only a certain number of remote control signals can be stored, so all remote control controlled devices can be stored in one learning type remote control transmitter. The drawback is that the original purpose of remote control control cannot be achieved.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a learning type remote control transmitter that can remotely control an unlimited number of controlled devices.

[Means to solve the problem]

The learning type remote control transmitter of the present invention includes a receiving circuit that receives a remote control signal, an internal storage circuit that stores data corresponding to data output from the remote control signal receiving circuit, and an internal storage circuit that stores data corresponding to data output from the receiving circuit. a removable external storage circuit for storing data; a restoration circuit for restoring remote control signals using data read from the internal storage circuit or the external storage circuit; and a mechanism for removably attaching the external storage circuit; and a circuit for connecting the external storage circuit to the restoration circuit.

〔Example〕

Next, one embodiment of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a remote control transmitter 1 according to an embodiment of the present invention includes a controller 2 comprising a microprocessor, and a rewritable built-in memory circuit 3 connected to the controller 2.
, a keyboard 4, a remote control signal receiving circuit 5, a remote control signal transmitting circuit 6, and a removable external storage device 8 in the form of a card, for example, which includes a rewritable external storage circuit.
, a connection circuit 7 for connecting the external storage circuit to the controller 2, and a battery 9 for retaining the contents of the external storage circuit.

In the learning type remote control transmitter 1 of this embodiment, the controller 2 decodes the remote control signal sent from the receiving circuit 5 and converts it into a binary code. This binary code is stored in the built-in storage circuit 3 or the external storage device 8 together with the key data of the keychain 4. When you press the key on keyboard 4,
The same data as the key data of the key is searched out from the built-in storage circuit 3 or the external storage device 8, and the binary code stored together with the key data is read out. The controller 2 creates a remote control signal from this binary code and sends it to the transmission circuit 6.

〔Effect of the invention〕

As explained above, according to the present invention, by connecting a detachable external storage circuit to a learning type remote control transmitter,
The storage capacity for storing binary codes for restoring remote control signals can be freely increased, and there is no limit to the number of controlled devices, which can be controlled by one remote control transmitter.
