It is characterized in that it is configured to perform.

According to a fourth aspect of the present invention, there is provided a camera-integrated recording / reproducing apparatus in which a camera unit and a recording / reproducing unit are detachably mounted, and an image taken by the camera unit with the camera unit and the recording / reproducing unit combined. In a camera-integrated recording / reproducing apparatus that records signals in a recording / reproducing unit, a detecting unit that detects a detached state between the camera unit and the recording / reproducing unit, and the detecting unit detects that the camera unit and the recording / reproducing unit are in a separated state. A control unit for switching the power supplied to the camera signal reception processing unit in the recording / reproducing unit to a power reduction state.

An embodiment of the present invention will be described below with reference to FIGS. It is to be noted that components having the same functions as those in FIG.

The recording / reproducing unit 3 includes a camera signal receiving processing unit 6 which receives and processes the video signal 2 from the camera unit 1.
A VTR unit 3a involved in recording / reproducing of a recording medium; a power supply detection unit 7 as a detection unit for detecting an energization state to the camera unit 1; and a camera signal reception controlled by an output of the power supply detection unit 7. A switch unit 8 is provided as a control unit that controls power supply to the processing unit 6.

More specifically, as shown in FIG. 2, the power supply detecting section 7 is composed of a comparator 9, a detecting resistor 10, and a constant voltage source 11 for determining a set level. The line 12 is connected to the power supply circuit of the camera unit 1.

Since the minimum supply power of the camera unit 1 is known in advance, assuming that the supply current at that time is Id, the resistance value Rd of the detection resistor 10 is set so that the following inequality holds.
And the value of the output level Vd of the constant voltage source.

Vcc−Rd · Id <Vd where Vcc is the output voltage of the battery 4. In such a case, the output of the comparator 9 becomes “H” (≦≦) when power is supplied to the camera unit 1.
Vcc) level, when not performed, "L" (= GN)
D) level.

The switch section 8 sets the output of the comparator 9 to "
In the case of the "H" level, as shown in FIG. 2, the power supply line 13 to the camera signal reception processing unit 6 is connected to the battery 4, and the output is switched when the output of the comparator 9 is inverted to the "L" level. The circuit between the power supply line 13 to the battery 6 and the battery 4 is turned off.

With this configuration, the comparator 9
The power supply to the camera signal reception processing unit 6 is controlled according to the output state of the camera, and the power consumption of the camera-integrated recording / reproducing apparatus can be reduced.

Further, in this embodiment, the value of the current supplied to the camera unit 1 is detected as a voltage drop at the detection resistor 10, and if the voltage drop is below a set value, the camera signal reception processing unit 6, the power supply to the camera signal reception processing unit 6 can be controlled without increasing the number of wires connecting the camera unit 1 and the recording / reproducing unit. Since it can be applied to a camera-integrated recording / reproducing apparatus, its versatility is very large.

If the number of electric wires connecting the camera unit 1 and the recording / reproducing unit can be increased, the camera unit 1
The potential of a specific point having a different output level between the ON state and the OFF state of the power switch is detected on the recording / reproducing unit 3 side via an additional cable, and this detected potential is compared with a set potential to determine the energized OFF state. It is also possible to configure so as to determine and control the power supply to the camera signal reception processing unit 6.

In the above-described embodiment, when the power switch of the camera unit 1 is off, the switch unit 8 is automatically turned off to save power, but the camera unit 1 and the recording / reproducing unit 3
If the camera unit 1 is detachably configured, the state where the camera unit 1 is removed from the recording / reproducing unit 3 is detected, and the switch unit 8 is automatically turned off to realize power saving. Similar effects can be expected.

In each of the above embodiments, when the power switch of the camera unit 1 is turned off or the detachment of the camera unit is detected, the power supply to the camera signal reception processing unit 6 is completely turned off. But this is the camera part 1
The power supply voltage to the camera signal reception processing unit 6 is switched to a lower voltage value when it is detected that the power switch of the camera is turned off or the camera unit is removed. Can be achieved.
