Abstract

PURPOSE:To remote-control plural pieces of equipment with one key operation by registering plural key input data to a memory and transmitting plural commands with one key operation. CONSTITUTION:When a key inputted by a key input part 1 is a program request key to operate plural pieces of equipment, a program part 3 switches a switch 2 to a (b) contact side. Key data from the key input part 1 are successively written to the memory of a registering part 5. Next, when the key to successively read the key data of the registering part 5 is inputted, a deciding part 4 decides the key input and switches a switch 6 to a contact (d) side. The registering part 5 to receive instructions sends the key data to a decoder part 7 from the memory successively, and an oscillating pulse string corresponding to the key data is transmitted from a transmitting part 8. Thus, only by operating one key, plural pieces of equipment can be simultaneously remote-controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a programmable remote control transmitter used in various home appliances.

Conventional technologyCurrently, many of the audiovisual appliances in home appliances can be controlled remotely using remote controls, especially AV.
Some device remote controls can control multiple devices. However, when a remote control is used to perform a desired operation by combining a plurality of these devices, it is necessary to operate a plurality of keys.

Hereinafter, an example of the conventional remote control transmitter as described above will be described with reference to the drawings. FIG. 2 is a simple block diagram of a conventional remote control. In FIG. 2, 9 is a part of the remote control key, 10 is a key scanning unit that scans keys pressed by the remote control part 9 and converts them into data;
Reference numeral 1 denotes a pulse generator that converts data from the key scan unit 10 into an oscillation pulse train, and 12 a transmitter that converts the oscillation pulse train into an optical signal and outputs it.

In the remote control transmitter configured as described above, first, when the remote control transmitter is used to cause the receiving home appliance to perform a desired operation, the command to perform the desired operation is
The data is input from the remote control key part 9 and converted into data by the key scanning part 10.

Next, the pulse generator 11 converts the data into an oscillation pulse train, and the transmitter 12 outputs the oscillation pulse train as an optical signal.

Problems to be Solved by the Invention However, in the above configuration, there are cases where multiple home appliances are interconnected and the purpose cannot be achieved unless all of them are operated, or when multiple home appliances cannot be operated at the same time. If desired, there is a problem in that multiple keys must be pressed for each action or device.

The present invention is intended to solve the above-mentioned conventional problems and to provide a programmable remote control transmitter having a function of transmitting a plurality of key data with a single key operation.

Means for Solving the Problems In order to solve the above-mentioned conventional problems, the programmable remote control transmitter of the present invention stores a plurality of key input data in the memory and automatically stores the data by pressing one key. It is equipped with a program function that can send out the transmission codes in the set order, and a transmission function.

Effect The present invention has the above-described configuration, so that multiple commands can be transmitted with a single key operation, and in response to multiple commands,
There is no need to perform each key operation once.

Embodiment Hereinafter, a programmable remote control transmitter according to an embodiment of the present invention will be explained with reference to the drawings.

FIG. 1 is a functional block diagram of a programmable remote control transmitter in one embodiment of the present invention. In the figure, reference numeral 1 denotes a key input section, which is composed of an input key, a key scan circuit, and a key code generation circuit, and converts a pressed key into specific key data and outputs the same. Reference numeral 2 denotes a switching unit that switches from a normal state to a programmable state when an instruction by key input requests operation of a program function. 3 is a program unit that determines whether the key data from the key input unit 1 requests a program function, instructs the switching unit 2 to enable programming, and sends the key data to the registration unit 5. It is to be registered.

4 is a determination unit that determines whether the key data instruction from the key input unit 1 requests output of the key data registered in the registration unit 5, and switches to the switching unit 6 as necessary. Outputs a signal that instructs. The registration section 5 is composed of a memory and a memory controller, and the program section 3 registers a plurality of key data in the memory, and the memory controller sequentially outputs the key data according to instructions from the judgment section 4. 7 is the decoder section,
The key data passing through the switching unit 6 is converted into an oscillation pulse train.

Reference numeral 8 denotes a transmitting section, which is composed of an oscillator 2 and a light emitting section, and converts the oscillation pulse train sent from the decoder section 7 into light.
Transmission is performed from the light emitting section.

Regarding the remote control transmitter configured as above, the first
The operation will be explained with reference to the figure. First, in a normal remote control operation, an input key pressed in the key input section 1 is converted into specific key data by the scan circuit and sent to the switching section 2 and the program section 3. The program unit 3 determines whether or not there is a key that requests a program and the input key data requests a program operation. If the program unit 3 does not request a program operation, the switching unit 2 Leave it as it is without giving any specific instructions, or
Send a signal to maintain. When the program is not executed, the key data is sent to the judgment unit 4, which further judges whether or not the key data requests the output of the registered key data, and if necessary, switches the key data to the judgment unit 4. 6 outputs a signal requesting switching. When the registered key data is not output, the key data when pressed is sent as is to the decoder section 7, and the data is converted into an oscillation pulse train. The transmitter 8 receives and receives this oscillation pulse train, converts it into an optical signal, and sends a command to each device.

Next, the operation during programming and the operation when outputting registered data by the program will be explained. If the key input through the key input section 1 is a key that requests a program, the program section 3 makes a judgment and puts the switching section 2 into a programmable state. From this state, the program section 3 stores the key input section 1 in the memory in the registration section 5.
It performs an operation of sequentially writing the key data from . When the program processing as described above is completed, when a key for requesting termination of the program is pressed from the key input section 1, the program section 3 switches the switching section 2 to the normal state.

Next, when there is a key in the key input unit 1 that requests the key data written in the memory of the registration unit 5 to be output in order, and that key is pressed, the determination unit 4 outputs the key data written in the memory of the registration unit 5. The content of the request is determined from the above, and the switching section 6 is switched so that the key data is sent from the registration section 5 to the decoder section 7. Upon receiving the instruction, the registration unit 5 sequentially sends the key data from within the memory to the decoder unit 7. From then on, as in normal operation, the decoder unit 7 converts each data into an oscillation pulse train, and the transmission unit 8 receives and transmits the key data. and send. The final operation is repeated by one program until the registered data is finished.

Effects of the Invention As described above, according to the present invention, a plurality of keys that are constantly used can be combined into one key, thereby eliminating the need to perform key operations many times.
