Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device equipped with a wireless remote control receiver.

[0002]

2. Description of the Related Art A conventional wireless remote controller (hereinafter referred to as "remote controller") consumes a few mA of current in a receiving circuit.
Particularly in battery-powered devices, reducing the power consumption of the remote control receiver when the remote control is not used has been an issue.

FIG. 3 shows a block diagram of a conventional remote control receiver. FIG. 4 shows a perspective view of a video camera and a remote control transmitter incorporating a conventional remote control receiver.

In FIG. 3, 31 is a receiving means for receiving data from a remote controller transmitter, 32 is remote control receiving data determining means for determining remote control receiving data output from the remote control receiving means 31, and 33 is a remote control receiving data determining means. A power supply means for managing the power supplied to the remote control reception means 31, and a remote control on / off switch 34 for controlling the power supply from the power supply means 33 to the remote control reception means 31.

In FIG. 4, reference numeral 41 is a remote control transmitter, 42 is a video camera incorporating a remote control receiver, 43 is remote control receiving means for receiving data from the remote control transmitter 41, and 44 is remote control reception. Means 43
It is a remote control ON / OFF switch for controlling ON / OFF of the power.

A device (hereinafter, abbreviated as a main body) having the remote control receiving means configured as described above will be described below with reference to FIGS.

When the video camera is operated by the remote control transmitter, the remote control ON / OFF switches 34 and 44 are switched to the ON side. The remote control on / off switch 34 outputs a control signal for causing the power supply means 33 to supply power to the remote control receiving means 31 and 43 by switching to the on / off switch. The power supply means 33 supplies power to the remote control receiving means 31 in response to a control signal from the remote control on / off switch 34. The remote control receiving means 31, 43 are in a remote control receivable state by the power supplied from the power supply means 33. By pressing the operation key of the remote control transmitter 41, data is output from the remote control transmitter 41 and input to the remote control receiving means 31, 43. The remote control reception means 31 performs waveform shaping on the input data and outputs the data to the remote control reception data determination means 32. The remote control reception data discrimination means 32 inputs the data from the remote control reception means 31, performs discrimination of data contents and error detection,
The remote controller input data is output to the control unit of the video camera.

In order to prevent erroneous operations and reduce power consumption of the video camera, the video camera is controlled by the remote control transmitter 4
When it is made impossible to operate with 1, the remote control switch 34, 44 is switched to the switch side. The remote control on / off switch 34 outputs a control signal for stopping power supply to the remote control receiving means 31 to the power supply means 33 by being switched to off. The power supply means 33 stops the power supply to the remote control receiving means 31 in response to a control signal from the remote control on / off switch 34. The remote control receiving means 31 does not operate because the power supply means 33 stops the supply of power. Even if data is output from the remote control transmitter 41 by pressing the operation key of the remote control transmitter 41, the remote control reception means 31 and 43 do not operate, so that data is not output to the remote control reception data determination means 32 and the video data is output. Since the remote controller data is not output to the control unit of the camera, the remote controller cannot be operated.

[0009]

However, in the conventional method, unless the user of the video camera intentionally turns off the switch for turning on / off the remote control, the operation of the remote control cannot be prevented and the power consumption of the main body cannot be reduced. Had a problem that it was necessary to always recognize and be aware of the remote control switch.

The present invention solves the above-mentioned conventional problems. When the user does not use the remote control, the remote control transmitter is turned off by mounting the remote control transmitter in the mounting slot provided in the video camera body. An object of the present invention is to provide a wireless remote control receiver that enables the user to prevent erroneous operation of the remote controller and reduce power consumption without being aware of it.

[0011]

In order to achieve the above object, a wireless remote control receiver of the present invention comprises a receiving means for receiving data from a wireless remote control transmitter and remote control reception data output from the receiving means. Remote control reception data determination means for determining, remote control transmitter attachment detection means for detecting that the wireless remote control transmitter is attached to a device including the reception means, and power supplied to the reception means is the remote control transmitter. And a power supply means for managing by a control signal from the mounting detection means.

[0012]

According to the present invention, when the remote control transmitter is mounted in the mounting slot prepared in the main body when the remote control transmitter is not in use, the remote control transmitter mounting detection means recognizes and outputs a control signal to the power supply means. . The power supply means stops the power supply to the remote control receiving means in response to the control signal from the remote control transmitter mounting detection means. A mounting slot is provided so that the remote control transmitter can be mounted on the main body, and by detecting the mounting state of the remote control transmitter, it is determined whether the remote control transmitter is intended to be used or not. When it is determined that the user has no intention of using the remote controller, the remote controller receiving unit is turned off to prevent erroneous operation of the remote controller and reduce power consumption of the main body without the user's awareness.

[0013]
