Abstract

PROBLEM TO BE SOLVED: To prevent video equipment and audio equipment from performing operation that a user does not desire even if a person other than the user operates the remote controller by providing the remote controller for the video equipment and audio equipment with a password setting function and previously storing a password. SOLUTION: A microcomputer is built in the remote controller to provide a password setting and storing function. The microcomputer decides whether or not password setting key input is done in a step T1 to enable normal steps T8-T10 when not or input and register a password and then enters a wait state in steps T2-T4 when the password setting key input is done. In this wait state, a password is set and only when the password matches the password registered in the step T3, remote control operation becomes possible. Consequently, even if a person other than the user operates the remote control, the video equipment and audio equipment can be made not to perform operation that the user does not desire.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote controller for operating a video device and an audio device, and more particularly to a remote controller for setting a password so that a user other than a user cannot perform a careless operation.

[0002]

2. Description of the Related Art As shown in a flowchart of FIG. 2, a conventional remote controller transmits a remote control code corresponding to a key operated from the remote controller by infrared operation or the like by operating a key of the remote controller, and then operates the remote controller. Until it is in a standby state. The video equipment and the audio equipment receive the transmitted remote control code at the light receiving unit, and perform an operation corresponding to the received remote control code.

[0003]

However, in the above configuration, a person other than the user using the video equipment and the audio equipment, such as a child, mischiefs the remote controller and suddenly presses the operation keys. Undesired behaviors of the user, for example, raising and lowering the volume, switching channels, etc., may cause discomfort. In addition, when a recording or recording key such as a video or a cassette has a recording or recording function, pressing the recording or recording key erases images and music recorded on the video tape or the cassette tape and the recorded data is recorded. The problem of losing images, music, etc. occurs.

[0004]

According to the present invention, in a remote controller for operating a video device and an audio device, a password setting function is provided in the remote controller.
And a microcomputer that stores the password is built in, a password is set by pressing an arbitrary operation key of the remote controller several times or several times, the password is stored in advance, and the same password as the stored password is input. This is achieved by transmitting a remote control code from the remote controller when it can be recognized that the video device and the audio device can be operated.

[0005]

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
A description will be given based on the flowchart of FIG. First, in step T1, it is determined whether or not the remote controller has entered the password setting mode. Next, step T2
Then, the user presses the operation key of the remote controller and inputs an arbitrary password. Then, step T3
Then, the input password is stored by the microcomputer built in the remote controller. Step T4
Is the standby state of the remote controller. Step T above
According to the procedure of 1 to T4, the password of the user is registered in advance.

Next, in step T5, the user inputs a password to operate the remote controller,
It is determined whether the password is the same as or different from the password stored in the microcomputer. At this time, if the passwords are the same, the user operates the keys of the remote controller in step T6, and the remote controller transmits the remote control code in step T7 to operate the video equipment and the audio equipment.

On the other hand, when the password is not stored in the microcomputer as in step T8 or when the user has not entered the password setting mode and the user presses the operation key of the remote controller, the remote control code is transmitted in step T9. . Step T10 is a standby state of the remote controller. Steps T8 to T10 above
According to the procedure described above, it becomes possible to operate the video equipment and the audio equipment even if a password has not been set.

In step T11, if the password is not entered after recording the password, or if the operation key is pressed when a different password is entered, the remote control code is not transmitted in step T12. The device cannot be operated.

[0009]

According to the above configuration, the remote controller according to the present invention is a remote controller for operating a video device and an audio device, wherein the remote controller has a built-in password setting function and a microcomputer for storing the password. A password is set by pressing an arbitrary operation key of the remote controller several times or several times, stored in advance, and when it can be recognized that the same password as the stored password has been input, the remote controller The remote control code can be transmitted from the camera to operate the video and audio equipment, so that anyone other than the user using the video and audio equipment, such as a child, mischiefs the remote controller and suddenly operates the operation keys. The remote control code is not sent when I press it Behavior unwanted users, for example Boryuumu raise and lower or, need not be a uncomfortable because they are not switching channels. Also, for video and cassettes that have a recording and recording function, even if the recording or recording key is pressed on the video tape or cassette tape, the password is not entered and the remote control code is not transmitted because the password is not entered. Alternatively, there is an advantage that the image and music recorded on the cassette tape are not erased, so that the recording is not lost.
