Abstract

PROBLEM TO BE SOLVED: To attain easiness of camera recording and power interruption by using a recording circuit and its mechanism utilizing means and providing a recording circuit and its mechanism utilizing means to another part so as to generate a signal to control a microcomputer and a camera microcomputer. SOLUTION: When a switch 1 is set to an OFF position and a switch 2 is turned off, an output signal of a multiplier circuit 3 goes to a high level because of receiving high level signals to interrupt power and the camera is not operated. Only when the switch 2 is closed, an output of the multiplier circuit 3 goes to a low level and a microcomputer 6 receives the camera operation and an output of an adder circuit 5 goes to a high level even when the switch 1 is set to the position of a VTR and the camera operation is accepted. A switch operation function 2 is added to another position to generate a signal to control the microcomputer and a camera microcomputer, thus to facilitate the camera recording and power interruption.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera-integrated VTR.
Recording system.

[0002]

2. Description of the Related Art A conventional camera-integrated VTR does not have a camera recording system according to the above-mentioned method.

However, in a conventional stationary VTR, there is a system in which even when the power is turned off, a tape detection circuit and a mechanical unit operate by inserting a video cassette tape to enable recording and reproduction.

[0004]

In the prior art, when performing camera recording, a switch for arbitrarily recording the camera is operated and then recording is performed. When the recording is completed, the switch is also optionally returned to the original position. I had to do that. For this reason, it takes time to start camera recording, the problem is that the switch must be operated arbitrarily even after recording ends, and if this operation is not performed, the camera is always turned on. In such a case, the battery is unnecessarily consumed. In the above-mentioned stationary VTR system, the power is turned on by inserting the tape, but the power is not turned off unless a certain operation is performed after the tape is inserted. Integral VTRs cause problems, and therefore do not contribute to improving the usability of the equipment.

[0005]

In order to achieve the above-mentioned object, the present invention provides a camera recording circuit and a mechanism using the mechanism provided by the conventional camera recording circuit, and by providing a means for recording a camera in another place. Enables a system that turns off camera recording and power.

[0006]

FIG. 1 is a block diagram showing an embodiment of the present invention.
2 (a), 2 (b), 2 (d) and 2 (e). In FIG. 1, reference numeral 1 denotes an operation switch for arbitrarily recording or reproducing a camera recording or an external input signal. 2 is a switch added at another place according to the present invention to detect the position of the device,
Camera recording ready state or switch to turn off the power. Reference numeral 3 denotes a multiplication circuit for the signals of the switches 1 and 2. 4 is 3
Output signal inverting circuit. 5 is a circuit for adding the signal on the VTR side of the switch 1 and the output signal of 4. 6 is a camera-integrated VT
A microcomputer that controls R. Reference numeral 7 denotes a microcomputer that controls the camera unit.

FIGS. 2 (a) and 2 (b) show a switch operation mechanism added at another place. In FIGS. 2A and 2B, reference numeral 8 denotes a detection switch when the camera recording state is not held. The switch 8 indicates that the switch is not pressed, and the switch 9 indicates
The switch 10 is not pressed because the elastic piece of No. 8 is not in contact with the switch 8 (the switch 10 is the same as the switch 2 in FIG. 1). Section A is a sectional view of the switch 8 and is held by a spring so as not to contact the elastic piece 9. As an example, FIG. 2C shows the state of the device when the photographer does not perform camera recording. FIGS. 2D and 2E show a camera recording preparation state, which is opposite to FIGS. 2A and 2B.
When the switch a is pressed (8a is in the state B), it comes into contact with the elastic piece 9a and the switch 10a is pressed. As an example, FIG. 2 (f) shows the photographer in a camera recording preparation state.

The feature of FIG. 1 is that the conventional arbitrary camera recording,
By adding a switch other than the switch for VTR recording / reproduction such as an external input, a signal for controlling the microcomputers 6 and 7 can be generated, so that the camera recording and the power can be easily turned off without using the conventional switch. It is possible.

In FIG. 1, when the switch 1 is off and the switch 2 is off, Hi and Hi signals are input to the multiplying circuit 3 and the output signal of the multiplying circuit 3 is Hi. . Here, since the microcomputer a of 6 receives the camera operation by the Lo signal, the camera does not operate at this time (the power is turned off). 2 (a), 2 (b) and 2 (c). However, when only the switch 2 is turned on, Hi and Lo signals are input to the multiplying circuit 3 and the output of 3 is a Lo signal.
Accepts camera operation. In other words, if the photographer sets the device to the position where camera recording is to be performed as shown in FIG.
Since the switch and the shoulder of the photographer become contact points and the switch 8 is pressed to accept the camera operation, camera recording can be easily performed. Also, as shown in FIGS. 2A, 2B and 2C, 8
When the switch is no longer pressed. That is, when the photographer ends the camera recording and releases the device from his / her shoulder, the switch 2 is turned off and the power is turned off. Further, in FIG. 1, when the switch 2 is turned on even when the switch 1 is on the VTR side, the Lo signal from the switch 1 and the switch 2
From this, the Lo signal is output through the multiplication circuit of 3 and becomes the Hi signal by the inversion circuit of 4, so the output of the addition circuit of 5 is H
i. Therefore, since the microcomputer b receives the VTR operation by the Lo signal, it accepts the camera operation without performing the VTR operation.

According to this embodiment, if a camera recording circuit and its mechanism, which are conventional functions, are used and recording can be performed by adding them to another location, the photographer does not need to operate the switch arbitrarily. If the position of the device is the camera recording position, the camera operates so that the camera can be easily recorded. If the position of the device is not the camera recording position, the power is turned off, so there is no forgetting to turn off the power and the power of the battery is saved, so that it is convenient Can be improved.

[0011]

According to the present invention, it is possible to generate a signal for controlling the microcomputer and the camera microcomputer by adding the camera recording circuit and the mechanism thereof, which are the conventional functions, to a different place. Since the camera recording operation is performed depending on the position, camera recording can be easily performed. In addition, when the position of the device is not the camera recording position, the power is turned off, and the power is not forgotten to be turned off.
