18 Effects According to the present invention, it is possible to remotely control the video recording and reproducing apparatus using the operation means and to monitor it using the video display means.

G. Examples Examples of the present invention will now be described in detail with reference to the drawings.

G-1, Example 1 First, description will be given with reference to FIG. 1, which is a schematic perspective view. The monitor device 10 of this embodiment has a liquid crystal display 11 as an image display means. The casing 12 is formed with steps, and the liquid crystal display 11 is rotatably provided on the concave surface 12A of the casing 12. The liquid crystal display 11 is a full-color display and is approximately several inches in size. Further, the convex surface portion 12B of the housing 12 is provided with an operation section 13 having operation buttons 13A to 13E for remotely controlling the video tape recorder 20. The operation button 13A is a rewind operation button, the operation button 13B is a playback operation button, and the operation button 13C is a fast forward operation button. Further, the operation button 13D is a stop operation button,
The operation button 13E is a pause operation button. Although not shown here, a backline N7, which will be described later, is provided on the back side of the liquid crystal display 11, and a speaker 19, which will be described later, is provided inside the casing 12. Further, a cable 15 having a connector 14 at its tip is pulled out from inside the housing 12, and the connector 14 is connected to a connector 21 on the video tape recorder 20 side. This video tape recorder 20 is, for example, a small portable one.

In addition, when shooting, the video tape recorder 2
A video camera (not shown) is connected to 0.

Next, description will be given with reference to FIG. 2, which is a block circuit diagram showing the configuration of main parts. The video tape recorder 20 has a power supply circuit 22, a video signal output circuit 23, an audio signal output circuit 24, and a remote control circuit 25. The power supply circuit 22 is, for example, a storage battery (battery), and the monitor device 10 supplies the power supply voltage vP. The video signal output circuit 23 and the audio signal output circuit 24 are circuits that output a video signal Sv and audio signals reproduced from the magnetic tape. In addition, the remote control circuit 25
is a circuit that causes each section of the video tape recorder 20 to perform a predetermined operation in response to a control signal Sc from the operating section 13 of the monitor device 10.

In the monitor device 10, the power supply voltage Vp from the power supply circuit 22 is supplied to the valley portion. Further, the video signal Sv from the video signal output circuit 23 is subjected to predetermined processing in the video signal processing circuit 16, and then supplied to the liquid crystal display 11, and the video is displayed on the liquid crystal display 11. At this time, the backlight 17 illuminates from the back. Further, the audio signal S from the audio signal output circuit 24 is supplied to the speaker 19 via the amplifier circuit 18, and the speaker 19 emits audio. The operation unit 13 outputs a control signal Sc corresponding to each operation button 13A to 13E.
is supplied to the remote control circuit 25 of the video tape recorder 20 to remotely control the video tape recorder 20.

According to such a monitor device 10, both the monitoring using the liquid crystal display 11 and the remote control of the video tape recorder 20 using the operation unit 13 can be performed at hand, which is very convenient. In addition, it is small, lightweight, and highly maneuverable, making it easy to use when shooting outdoors or inside a car. Furthermore, this monitor device 10 can be used not only for monitoring reproduced images, but also as a viewfinder during photographing, and for adjusting white balance prior to photographing.

G-2, Example 2 Next, a second example will be described. Note that the same reference numerals are given to the respective parts corresponding to those of the first embodiment described above.

As shown in FIG. 3, the monitor device 30 of this embodiment includes:
It is composed of a display unit 31 and an operation unit 32. That is, the divided display unit 31 and operation unit 32 are connected to the connector 33.3.
4, the monitor device 30 is configured. Also, the tuner unit 40 and display unit 31 can be connected to the connector 41 instead of the operation unit 32.
A small-sized television receiver can also be configured by connecting the two through .33. In the tuner unit 40, the top surface of the housing 42 has a channel selection operation button 43.4.
4 and a channel display section 45 are provided, and a rondo antenna 46 is provided on the side surface. Also, the fourth
As shown in the figure, a storage battery 47 and a team are included in the housing 42.
It has a circuit 48. This tuner circuit 48 is a circuit that receives the broadcast radio waves selected by the channel selection operation buttons 43 and 44 and outputs a video signal Sv and an audio signal Sp. The configuration of the display unit 31 is the same as the configuration of the monitor device 10 of the first embodiment described above (see FIG. 2), except that the operation section 13 is removed. Therefore, the explanation will be omitted.

According to the monitor device 30 described above, the same effects as in the first embodiment can be obtained. Furthermore, television receivers can be selectively configured, and the commercial value is extremely high.

G-3, Example 3 Next, an eighth example will be described. Note that the same reference numerals are given to the respective parts corresponding to those of the first embodiment described above.

As shown in FIG. 5, in the monitor device 50 of this embodiment, a portion of the housing 51 in front of the liquid crystal display 11 is sloped, and operation buttons 13A to 13E are provided in this portion. An operating section 13 is provided. Further, the monitor device 50 has connectors 52 and 53.
The video and tape recorder 20 are connected to each other. Furthermore, instead of the connector 53 on the video tape recorder 20 side, a small television receiver can be constructed by connecting the tuner unit 60 and the monitor device 50 through connectors 61 and 52. In the tuner unit 60, a tuning dial 63 and a channel display section 64 are provided on the top surface of the housing 62, and an O-rad antenna 65 is provided on the side surface.

By using the monitor device 50 described above, the same effects as in the first and second embodiments can be obtained. In addition, when the monitor load 50 and the tuner unit 60 are connected to configure a television receiver, the operation section 13 (operation button 13A
13E) are covered by the casing 62 of the tuner unit 60, so that the operating section 13 that is not in use can be removed from view.

It should be noted that the present invention is of course not limited to the embodiments described above, and the video recording and reproducing apparatus may be, for example, a camera-integrated video tape recorder.

H1 Effects of the Invention As is clear from the description of the embodiments described above, the monitor device of the present invention, which includes a remote control means for a video recording and reproducing device and a video display means, is easy to use and highly maneuverable.
