[Industrial applications]

 The present invention relates to a remote control transmitter in which a key function and a key arrangement can be arbitrarily set for a key input circuit having a transmission key according to the number of commands.

[0002]

[Prior Art]

 Recently, many AV devices can be remotely controlled by a wireless remote control from a remote location, but since the manufacturer's remote control code is uniquely set by the manufacturer, one remote control transmitter can be used by multiple manufacturers. I couldn't control my equipment. On the other hand, as a means of relieving such plight, a remote control transmitter with a learning function, which has a memory for storing remote control signals inside, has appeared, and some of the dissatisfaction of users so far has been resolved. The remote control transmitter 1 with a learning function shown in FIG. 6 has a function of learning a remote control signal that differs depending on the manufacturer, using a dedicated remote control device (not shown) attached to the remote control target device. That is, the remote control signal received by the photodiode 2 of the light receiving section is amplified by the amplifier circuit 3, and at the same time, the carrier component and the burst envelope are shaped in waveform. Generally, the remote control signal is transmitted as binary data of “1” and “0” and is transmitted by pulse position modulation (PPM) of infrared light, so that it is a burst with a carrier component of 40 kHz, for example. It has a signal waveform in which periods and rest periods are alternately arranged. The CPU 4 writes the remote control code in the memory 6 while recognizing which transmission key of the key input circuit 5 is pressed. This remote control code is usually classified into about 6 types, and is divided into burst duration time and pause time, the number of pulses included in the burst, and signal generation procedure data. Stored in. When the remote control command is transmitted, the CPU 4 assembles and reproduces the signal and drives the infrared light emitting diode 7 to output it.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional remote control transmitter with a learning function 1 needs to individually learn the remote control command for each transmission key of the key input circuit 5 before use, and the remote control from the dedicated remote control transmitter attached to the equipment is used. When a command is received, it is once categorized into several types of remote control codes, then further divided into burst periods and pause periods, the number of pulses included in the burst, and the data of the procedure for generating signals, and the individual data are numerically divided. It is necessary to perform the work of digitizing and storing it in the memory 6, that is, the work of digitizing and recognizing the characteristics of the remote control command. However, in order to perform such recognition work, a considerably complicated circuit is required, and when an error occurs in the process of recognition work, it may not be effective in actual use. Also, although there is a natural limit to learning ability due to the limit of memory capacity, there is a tendency to place as many send keys as possible because of the emphasis on versatility, and as a result, it is possible to actually transmit at a normal frequency. There are many learning cases in which there are transmission keys that are rarely used or rarely used in addition to the transmission key to be used. There was a big difference with the vessel, and there was a problem that expectations could be disappointed.

[0004]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 is a perspective view showing an embodiment of the remote control transmitter of the present invention, FIG. 2 is a schematic circuit configuration diagram of the remote control transmitter shown in FIG. 1, and FIG. 3 is a remote control code data shown in FIG. 2 is a conceptual diagram showing the relationship between the remote control code and the remote control code stored in the memory. FIG. 4 is a flowchart for explaining the operation of the CPU shown in FIG.

The remote control transmitter 11 shown in FIG. 1 includes nine transmission keys 12 having key numbers 1 to 9, and four function keys 13, an up key 14, a down key 15 and a memory key 16. 2 keys, and these keys 12 to 16 constitute the key input circuit 17 shown in FIG. However, the up key 14 and the down key 15 are collectively treated as the function key together with the function key 13 in the description of the utility model registration claim. Further, in the embodiment, since the remote control transmitter 11 can function as the minimum necessary operation command base desired by the user, the key input circuit 17 includes only a small number of transmission keys that can meet the minimum required requests. It is assumed that there are only 12 transmission keys, for example, 6 transmission keys are used for a television and the remaining 3 transmission keys are used for a video.

The CPU 18, which has a central function of the remote control transmitter 11, controls the display unit 19, the remote control code / data table 20, the memory 21, and the output circuit 22 in addition to the key input circuit 17. The display 19 displays the content of the remote control command given by key input to the key input circuit 17, such as "power on / off" or "channel up". The remote control code / data table 20 is composed of a read-only memory and comprehensively stores remote control codes relating to remote control signals for all existing remote control code systems. That is, in the embodiment, the remote control codes of all manufacturers are stored according to the operation contents, and, for example, a power on / off command, a channel up / down command, a volume increase / decrease command, a TV / video switching command, etc. As shown in FIG. 3, the content of the remote control command is used as an index and stored as a remote control code for each manufacturer entering the market. The memory 21 is composed of an S-RAM or the like that can be read and written at any time, and the remote control code read from the remote control code / data table 20 in response to a key input is stored in association with the transmission key 12, and is normally transmitted. The remote control code is read in response to the key input by the key 12. The output circuit 22 outputs the remote control code read from the memory 21 corresponding to the transmission key 12 when the key input circuit 17 receives any key input.

Here, for example, when the transmission key 12 having the key number 1 is to be responsible for the power ON / OFF function of the AV device manufactured by P company, first, as shown in step (101) of FIG. 4, the function key 13 is pressed to The remote control code / data table 20 is set in a state in which any function can be selected. Next, in step (102), referring to the display on the display 19, the up key 14 or the down key 15 is operated to scroll the screen, and the keys are operated until the desired function is displayed on the display 19. Then, when the display unit 19 displays "power on / off", the operation of the up key 14 or the down key 15 is stopped. Next, in step (103), the transmission key 12 with the key number 1 is pressed toward the AV device manufactured by P. Co., which is the actual remote control target device. In this case, each time the send key 12 is pressed, in step (104), the CPU 18 reads out the remote control codes registered in relation to the “power on / off” in the remote control code data table 20 one by one, and reads them. It is transmitted via the output circuit 22. For this reason, the remote control target device actually turns on the power only when a remote control code that matches its own remote control code system is transmitted.

In the embodiment, the user himself / herself makes the judgment in step (105), and when the transmission key 12 having the key number 1 is pressed several times, the remote control signal is actually sent when the remote control target device operates. The effectiveness of can be confirmed. Then, in order to register the remote control signal whose effectiveness has been confirmed in the memory 21, the memory key 16 is pressed in step (106), and the remote control signal transmitted immediately before is set as the function of the transmission key 12 having the key number 1. .. That is, as shown in step (107), when the memory key 16 is pressed, the remote control code indicating power on / off is transferred from the remote control code data table 20 to the memory 21 via the CPU 18, and the key number is transferred. It is stored corresponding to the first transmission key 12. In the same manner, a channel up / down command, a volume increase / decrease command, or a TV / video switching command can be set for the transmission key of the desired key number.

As described above, the remote control transmitter 11 sequentially specifies remote control commands by specifying remote control commands from the remote control code data table 20 that comprehensively stores the remote control codes related to a plurality of remote control commands according to the contents of the remote control commands. The remote control code determined to be effective is stored in the memory 21 in association with any transmission key 12, and in actual use, it is stored in the memory 21 in correspondence with the transmission key 12. Since it is configured to output the read remote control code, it does not depend on the remote control code system that controls the remote control target device, that is, regardless of the manufacturer that uses its own remote control code. The transmission key 12 that the user arbitrarily specified in consideration of usability on the key arrangement and frequency of use A desired remote control command can be transmitted by operating. In addition, it is possible to list all remote control codes of existing equipment manufacturers and store them in the remote control code data table 20. Therefore, no matter what equipment the user selects for remote control, the remote control code The remote control code stored in the data table 20 can be used.

Further, the remote control target device actually moves only when the remote control code is sequentially read out by actually designating the remote control command and it is determined that the remote control code is effective, that is, in response to the remote control command. After confirming that, the remote control code is transferred from the remote control code / data table 20 to the memory 21. Therefore, there is no possibility that the remote control code or the data table 20 malfunctions or does not work well when actually used. Also, since the user can set an arbitrary function to the transmission key 12 having a favorite key number, it is possible to make any setting according to the difference in the dominant hand such as left-handed and right-handed, and personal preference, and the full key Unlike the attached remote control transmitter, by providing the minimum required functions, it is possible to provide a convenient remote control transmitter dedicated to personal use.

In the above-described embodiment, the setter judges that the remote control target device actually responds to the remote control commands sequentially issued from the remote control transmitter 11, and the memory key 16 is pressed. The remote control target device side can be configured to receive a response from the remote control target device side in the form of a reply. A general remote control transmitter is usually sold as an accessory to a specific AV device such as a television receiver, a video tape recorder, or a laser disc player as a set together with the AV device. Some have an answerback function that sends back a response to the remote control signal to the remote control transmitter.

In the remote controller transmitter 31 shown in FIG. 5, for example, when an operation such as “recording” is performed by direct touch input on the side of the remote control target device, the CPU 18 that actually receives a reply from the device actually receives the reply. It is configured so that it is possible to judge that the recording operation has started and display the fact on the display unit 19. Therefore, the remote control transmitter 31 is provided with an input circuit 32 for receiving a reply from the remote control target device, and when the input circuit 32 receives the reply, the CPU 18 sends the remote control immediately before. The code and the key number are paired and stored in the memory 21. Therefore, it is not necessary for the user to press the memory key 16 himself. In addition, a remote control target device such as a video tape recorder connected to a television receiver or a monitor receiver has an input guidance function for instructing a procedure for key setting on the screen, so that the user can display the screen. The keys of the remote control transmitter 31 can be set according to the input guidance.

Further, in both of the above embodiments, the remote control code / data table 20 is formed into an IC card, and the remote control transmitters 11 and 31 are detachable, so that AV equipment using a new remote control code will be provided in the future. When appears, it is possible to newly support it by replacing the IC card.
