FIG. 6 is a block diagram of a control system in a conventional camera-integrated VTR, in which 20 is a system control section;
21 is a power supply unit that supplies power to each circuit; 22
Reference numeral 23 denotes an imaging device section that images a subject, converts the imaged object into an electrical signal, and outputs it; and 23 a rotary head magnetic recording device that records and reproduces the video signal output from the imaging device section 22 on a magnetic tape. In the reproduction device section (hereinafter referred to as "VTR section"), 10 is an electronic view finder.

Next, the operation of this conventional camera-integrated VTR will be explained.

The system control unit 20 is a circuit block that controls the operation of the entire system, and includes the power switch 1,
In addition to the eject key 2, information is obtained from the various operation switches shown in FIG. 5 and various sensors not shown, and various power control signals and various system control signals are output, and the is brought into a predetermined operating state, and various display devices are made to display various operations. The power supply unit 21 supplies necessary power to each circuit unit based on various power control signals from the system control unit 20.

Conventional integrated camera configured like this
When shooting with a VTR, follow the steps below. First, when the power switch 1 is turned on, power is supplied to the necessary circuit blocks by a power control signal from the system control section 20. Next, operate the eject key 2 to lift up a cassette storage case (not shown), insert a cassette tape (not shown), and then push down the cassette storage case to set the cassette. Next, when the pause key 13 is operated, the magnetic tape is loaded and the entire apparatus enters a recording standby state. In this recording standby state, power is supplied to all circuit blocks necessary for photographing a subject and recording it on a magnetic tape. Therefore, the photographer confirms the subject image on the electronic viewfinder 10, performs the necessary operations such as setting the composition and adjusting the focus, and then operates the start/stop key 9 to start recording. Ru. When recording is to be stopped, the start/stop key 9 is operated again to stop recording, and the entire apparatus returns to the recording standby state. Normally, a photographer repeatedly operates the start/stop key 9 to take pictures of several objects, and repeats recording and stopping recording.

Generally, a portable camera-integrated VTR is used with a battery 11 as shown in the figure. In the recording standby state, almost the same amount of power is consumed as during recording. In other words, the power consumption of currently commercially available camera-integrated VTRs during recording is about 5 to 8W, and in the recording standby state, the power consumption during recording is about 90W.
% power consumption.

Currently, the battery capacity of the battery 11 is generally set to allow continuous recording for about 1 hour, and since the battery capacity of the battery 11 does not have much margin, the recording standby state continues for about 5 minutes. It is configured to automatically go into standby mode. In the standby state, the system control unit 2 necessary to memorize the system state
0 and unnecessary circuit blocks other than necessary sensors and the like are not supplied with power. When the photographer wants to record again, the camera returns to the recording standby state by operating the standby switch 12, and in the recording standby state, operating the standby switch 12 shifts the camera to the standby state.

When the record view key 14 is operated in the recording standby state, the magnetic tape is rewound by a predetermined amount, and then the VTR section 23 enters the playback tape running state and plays back the already recorded signal for a predetermined time, and converts this playback signal into electronic data. After being displayed on the screen of the viewfinder 10, the recording standby state is resumed. This allows the photographer to check the recording status of the photographed subject image.

To play back a magnetic tape that has already been recorded, operate the playback key 6, the VTR unit 23 enters the playback mode, supplies the playback signal to the electronic viewfinder 10, and then operates the playback key 6.
0 screen, and a playback screen is also displayed on a monitor TV via a video output terminal (not shown). To stop playback, operate stop key 3.

In the recording standby state, operations other than the power switch 1, eject key 2, stop key 3, start/stop key 9, standby switch 12, and record view key 14 should be performed to avoid erroneous operations as described below. Therefore, if you try to play back in recording standby mode, you must first stop and
After operating the key to cancel the recording standby state, operate the playback key 6 to play back the signal, and
To shift from the signal reproduction state to the recording standby state, the stop key 3 is operated once and then the pause key 14 is operated.
This has the purpose of preventing erroneous key operations; for example, in the recording standby state, it is assumed that the photographer has the intention to take a picture.
This is to prevent the position of the magnetic tape from moving unnecessarily due to incorrect operation of playback key 6, FF key 5, or REW key 7, and also to prevent the position of the magnetic tape from moving unnecessarily due to incorrect operation of playback key 6, FF key 5, or REW key 7. Since it is thought that there is no start/stop key 9.
It also has the meaning of preventing unnecessary transition to the recording state due to erroneous operation.

FIG. 7 shows the state of transition of operating states by the operation keys described above.

In addition, as an example of another arrangement of operation keys, a record/playback switch key may be provided instead of the pause key 13, and when the power switch is turned on, the recording standby state is first set, and the record/playback switch is set.・
It is constructed with the idea of giving priority to recording, which switches to a recording standby state by key operation, and in order to prevent erroneous key operation, keys that are not needed for recording are covered with a cover to prevent inadvertent operation. There are some configurations.

[Problems that the invention aims to solve] Conventional camera-integrated VTRs are configured as described above, and in order to prevent erroneous operation of the operation keys,
System design considerations include covering unnecessary operation keys with covers, placing operation keys unnecessary for recording operations in locations that are difficult for the photographer to touch during shooting, and providing a pause key and record/playback switching keys. required consideration.

Furthermore, recently such camera-integrated VTRs have
There is a trend toward rapid miniaturization in pursuit of portability, and the surface area of devices on which operation keys should be installed is becoming smaller. There is a problem that it becomes difficult to operate.

This invention was made to solve the above-mentioned problems, and aims to provide a camera-integrated recording and reproducing device that has a simplified structure and system and is highly operable.

[Means for solving the problem] The camera-integrated recording and reproducing device according to this invention has the following features:
A camera-integrated recording/playback device consisting of a video camera section that converts a captured subject image into an electrical signal, and a recording/playback device section that has the function of recording and playing back the electrical signals from the video camera section on a magnetic tape.
