Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a remote control device that can be remotely controlled, and is particularly suitable for a camera-integrated VTR, an electronic camera, a radio cassette, and the like.

<Related Art> Conventionally, a television, a still camera, and the like have been provided with a remote control device using infrared rays for remote operation. For example, for a remote control receiver provided in a television, a signal is transmitted by infrared rays from the remote control transmitter using a remote control transmitter to switch channels, and the volume is increased or decreased.

Here, some remote control transmitters can be detachably attached to a main body such as a television. For example, a concave portion is provided in the main body, and a remote control transmitter is stored in the concave portion.

The remote control transmitter that can be attached to and detached from the main body is a useful function particularly for electric equipment used outdoors, particularly for a camera-integrated VTR and a still camera.

In other words, even when remotely controlling a camera-integrated VTR, etc., the user can carry the remote control transmitter without any particular awareness,
In addition, the trouble of putting the remote control transmitter in the pocket or the bag is eliminated, and the remote control transmitter can be removed from the main body on the spot and the remote control can be operated.

<Problems to be Solved by the Invention> However, if a recess for accommodating a remote control transmitter is provided in an integrated VTR or the like, there is a problem that the size of the device main body increases. Therefore, when the remote control transmitter is miniaturized to the minimum necessary, operability is sacrificed, such as omitting some switches and reducing buttons. That being said, it is conceivable that two remote control transmitters are standard equipment, one of which is made small enough to be housed in the main body, and the other is made a standard size, but this also causes a problem of increasing cost . It is also conceivable to set a standard-size remote control transmitter as an option, but it is considered expensive and not very meaningful.

On the other hand, a lens cap, such as a still camera, having a function of a remote control transmitter added to a lens cap has been developed. But,
When operating the lens cap as a remote control transmitter, the lens cap is detached from the lens and used, so that the lens may be damaged at that time.

The present invention has been made in view of the above conventional technology, and has as its object to provide a remote control device with improved portability and miniaturization of a remote control transmitter using input / output terminals attached to an electric device. Is what you do.

<Means for Solving the Problems> The configuration of the present invention that achieves the above object has a remote control light receiving unit attached to the electric device main body and a remote control transmitter that is detachable from the input / output terminal of the electric device main body. It is characterized by the following.

In addition, a power output terminal is provided in parallel with the input / output terminal, and the remote control transmitter is provided with a power input terminal connected to the power output terminal, and the remote control transmitter can be charged via the power input terminal. More preferably, a secondary battery is built into the remote control transmitter.

<Operation> A remote control transmitter is attached to and detached from the electric device using the input / output terminals of electric devices such as a camera-integrated VTR and a radio cassette. A configuration, for example, a concave portion is not required.

Therefore, not only electric equipment such as a camera-integrated VTR but also the remote control transmitter itself can be reduced in size.

<Example> Hereinafter, the present invention will be described in detail with reference to examples shown in the drawings.

1 and 2 show a first embodiment of the present invention. In this embodiment, the present invention is applied to a camera-integrated VTR.

That is, the camera body 1 includes a zoom lens 2, a viewfinder 3, a video input / output terminal 4, and an audio input / output terminal 5. Therefore, when the input / output switch 14 is switched to the input side, the other video deck or television tuner is connected to the input / output terminals 4 and 5 via connection cords, so that the camera-integrated VTR is connected.
Can be recorded.

Further, when the input / output changeover switch 14 is switched to the output side, it is possible to reproduce from the input / output terminals 4 and 5 on an external monitor television or the like via a connection cord.

Further, in the present invention, the remote control transmitter 6 can be attached and detached using the input / output terminals 4 and 5. That is, the remote control transmitter 6 is provided with fitting portions 7, 8 for fitting to the input / output terminals 4, 5, and the fitting portions 7, 8 are fitted to the input / output terminals 4, 5. Thus, the remote control transmitter 6 can be mounted on the camera body 1, and the fitting portions 7, 8
Can be detached from the camera body 1 by pulling out from the input / output terminals 4 and 5.

As shown in FIG. 2, the remote control transmitter 1 is provided with a switch 9 for reproducing, fast-forwarding, rewinding, stopping, or switching the zoom lens between wide-angle and telephoto.
An LED 10 is provided, and an electric circuit 11 for causing the light emitting infrared LED 10 to emit light by the switches 9 and an electric circuit 11
A secondary battery, for example, a Ni-Cd battery 12, for supplying power to the battery is provided.

On the other hand, the camera body 1 is provided with a remote control light receiving section 13 for receiving infrared light emitted from the remote control transmitter 6. The remote control light receiving section 13 transmits a command from the remote control transmitter 6 to the inside of the main body 1 and executes an operation intended for the command, for example, reproduction, recording, or the like, in the main body 1.

Further, in this embodiment, the remote control light receiving section 13 is directed obliquely downward so that various operations can be performed with the remote control transmitter 6 mounted on the main body 1. That is, the remote-control transmitter 6 has its emission infrared LED mounted upward with respect to the input / output terminals 4 and 5, and the remote-control transmitter 6 is positioned below the remote control light-receiving unit 13 in the mounted state. ing. For this reason, it is possible to transmit to the remote control light receiving unit 13 with the remote control transmitter 6 attached to the input / output terminals 4 and 5. Further, even if the remote control transmitter 6 is detached from the input / output terminals 4 and 5, the signal can be transmitted to the remote control light receiving unit 13 from a remote position.

In the present embodiment having the above configuration, the input / output terminals 4 and 5 are used to mount the remote control transmitter 6 on the camera body 1, and therefore, unlike the conventional case, no recess is required. Therefore, not only the camera body 1 but also the remote control transmitter 6 can be reduced in size and weight.

In the present invention, the input / output terminals 4 and 5 are used merely for mechanical positioning and fixing, and are not used by electrically connecting them.

However, when the power output terminal 14 for the RF converter is provided adjacent to the input / output terminals 4 and 5, it is convenient to use the output terminal 14 for charging the secondary battery. That is, the remote control transmitter 6 is provided with a power input terminal 15 fitted to the output terminal 14, and this terminal 15 is connected to the Ni-Cd battery 12, which is a secondary battery of the remote control transmitter 6. In this way, with the remote control transmitter 6 attached to the camera body 1, the Ni-Cd battery 1 is connected to the power output terminal 14 for the RF converter.
2 can be charged.

Further, in the above embodiment, since the remote control transmitter 6 also serves as a cover for the input / output terminals 4 and 5,
There is no dust or dirt on the surface.

Further, in the present invention, as in the above-described embodiment, a special configuration is not required on the main body side. Therefore, the remote control transmitter 6 may be separately sold as an option.

Next, a second embodiment of the present invention will be described with reference to FIG. In this embodiment, the present invention is applied to a radio cassette.

That is, the radio cassette 21 is provided with a cassette storage section 22, a speaker 23, an antenna 24, and an audio input / output terminal 25. A remote control transmitter 26 is provided detachably from the input / output terminal 25. The configuration of the remote control transmitter 26 is the same as the configuration of the remote control transmitter 6 described above.

On the other hand, the radio cassette 21 is provided with a remote control light receiving section 27, but its position is not in front of the mounted remote control transmitter 26 on the front of the radio cassette 21. Therefore, in the present embodiment, the remote control transmitter 26 is detached from the radio cassette 21 and used.

Therefore, also in the present embodiment, since the input / output terminal 25 is used to mount the remote control transmitter 26 on the radio cassette 21, no recess is required unlike the conventional case. Therefore, not only the radio cassette 21 but also the remote control transmitter 26 can be reduced in size and weight.

<Effects of the Invention> As described above in detail based on the embodiments, the present invention utilizes the input / output terminals of the electric device, so that the portability and miniaturization of the remote control transmitter can be improved. Also,
When a power output terminal is provided in addition to the input / output terminal, the remote control transmitter can be charged using the power output terminal.
