2. Description of the Related Art In a conventional remote control device capable of selectively using remote control codes of a plurality of devices, selection is designated by operating a key on the remote control. For selection, a table containing the manufacturer's name of the target device and key operations for model selection such as TV, video etc. is provided on the back of the remote control etc., and the remote control code of the desired device is set in the remote control according to this selection operation. I was going.

Further, a predetermined remote controller attached to an individual device, for example, a signal generated when a power ON key or the like is pressed is detected by a remote controller capable of receiving, and a manufacturer or a model depending on a difference in received signal. In some cases, the remote control is recognized and the remote control code of the desired device is set in the remote control.

Further, the remote control codes of a plurality of devices are registered in the remote control, and a function of selecting a desired device from the registered remote control codes is provided.
No. 571 or a target device, a response to a manufacturer code sequentially issued from the remote controller is detected to detect a light receiving unit provided on the remote controller side, and manufacturer setting is performed.
18285 and so on.

[0005]

In the conventional remote control device for each maker, the remote control code setting operation has to be set for each target model with reference to the instruction manual and the like, which is a complicated operation. Furthermore, there is a problem that the setting work must be performed again when the battery is replaced.

The present invention has been made in view of the above problems, and a purpose thereof is to perform a remote control code setting by only reading a barcode, thereby making it possible to eliminate a complicated operation. It is to provide a reading remote control device.

[0007]

In order to achieve the above object, the present invention converts a remote control code for remotely operating a target device into a bar code reading remote control device which stores a plurality of remote control codes. It is characterized by comprising means for reading device information, selecting a remote control code corresponding to the read information, and setting the remote control code in the remote control.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 5 shows a remote controller main body 501 and a bar code 504 according to the embodiment of the present invention. The barcode 504 is read by scanning the barcode on the scanner unit 503 of the remote controller.

FIG. 1 is a block diagram of the remote controller. 1
A scanner unit 01 includes an optical system for reading a barcode, a photoelectric conversion element, and a light emitting element for illuminating for reading. Reference numeral 102 denotes an infrared LED for performing remote control of the target device, and the infrared LED driver 103 controls light emission according to a control signal from the CPU 104. Reference numeral 105 is a key device for inputting an operation for remotely controlling the target device, and 106 is a ROM storing a program for controlling the entire remote controller.

Reference numeral 107 is a register for storing the address or pointer name in which the remote control code set of the target device is stored, 108 is a ROM in which the remote control code set for each manufacturer is stored, and 109 is a work for performing processing such as barcode reading. A RAM including an area. Reference numeral 110 is a lookup table that refers to the storage location of the remote control code set from the data obtained by reading the barcode.

FIG. 2 is a flow chart showing steps for selectively setting the remote control code set of the target model of the present invention of FIG. 1 by the bar code scanner.

This flowchart shows the process after the pressing of the bar code reading button is detected by the scan program of the key device shown in the block diagram 105. In step S201, the illumination element for reading the bar code is turned on, and the initialization processing of the RAM, the error counter, etc., which becomes the storage area of the bar code read data, is performed.

In step S202, in order to make the user aware that the initialization operation is completed and the reading operation may be started, a display indicating that the reading preparation is completed is displayed. This display is LE on the key device of the read start block diagram 105.
D etc. are provided to display blinking. In step S203, a signal from the scanner is detected. If the bar code signal is not detected, the process returns to step S202.

When a signal from the bar code scanner is detected in step S203, the process proceeds to step S204,
The read ready display is switched to the loading display and data is acquired. It is assumed that the read signal is waveform-shaped and output in the scanner. The shaped data is deciphered according to the bar code deciphering rule, converted into a digital code, and the process proceeds to step S205 to make the reading in progress display a reading completion display.

In step S206, the remote control code set lookup table for each manufacturer of the block diagram 110 is referenced with the decrypted digital code as a key in order to obtain the remote control code set set for the digital code decrypted in step S204.

It is checked whether the digital code decoded in step S207 exists in the reference table. If the reference result is obtained, the process proceeds to step S208, and the reference result, that is, the desired result is stored in the code set pointer register of the block diagram 107. The area address or variable in which the remote control code set is stored is set, and the selection processing of the desired remote control code set by the bar code is completed. Although not shown in the figure, the processing step following this processing is the CPU 104.
Refers to the table in the manufacturer's remote control code set ROM 108 with the value indicated by the code set pointer register 107 of the press signal from the key device 105, and outputs the remote control signal corresponding to the press key to the infrared LED driver 103.
The infrared LED 102 is controlled to emit light via the, and a desired device is controlled.

<Embodiment 2> In the configuration shown in FIG. 3, the manufacturer's remote control code set lookup table 110 of FIG. 1 is omitted, and the bar code is directly used as the address indicating the desired device in the manufacturer's remote control code set ROM 108. It is coded.

The read flow is shown in FIG.

In FIG. 4, step S206 shown in FIG. 2 is omitted, and the check content of step S207 is changed to step S401 for checking whether it is a valid address.
The processing flow is the same as that of FIG. 2 except for the changing unit.

[0021]

As is apparent from the above description, according to the present invention, when the remote control code is set, the bar code of the target device is simply read by the scanner equipped in the remote controller to check the manufacturer name, model name, etc. of the target device. Further, it is possible to obtain an effect that the remote control code can be easily set without requiring a complicated setting operation such as an input operation.
