Description

TECHNICAL FIELD The present invention relates to a video tape recorder (hereinafter referred to as VTR).
The present invention relates to a recording / reproducing apparatus such as the above, and particularly to miniaturization thereof.

2. Description of the Related Art In recent years, in a VTR that records video and audio on a magnetic tape by a rotating magnetic head, a device that is integrated with a TV camera and can record information obtained through the TV camera (camera integrated VTR) Is rapidly spreading. Since such a VTR with a built-in camera is often used for a long time while being carried, it is necessary to reduce its size and weight. Therefore, as one method, a camera-integrated VTR that uses a smaller cassette tape that is compatible with the cassette tape that has been conventionally used in a stationary VTR is used.

As shown in FIG. 3, in the camera-integrated VTR 50 using the small cassette 55, the signal from the camera section 56 is processed by the signal processing section 57, and the rotary head 49 is processed through the amplifier section 58 for amplifying or head switching the signal. To be recorded on the magnetic tape 48. And when trying to reproduce this signal, this camera-integrated VTR50 is equipped with a reproduction circuit 51 and a reproduction operation section 52, and then a signal line 54 is connected to a television 53 to use the camera-integrated VTR50 itself as a reproducer. Or,
Alternatively, as shown in FIG. 3, an adapter 59 for mounting the small cassette 55 on the stationary VTR 60 using the standard cassette 65 is used (for example, "TV Technology"'86.
November issue PP87-91). At this time, take out the small cassette 55 from the camera-integrated VTR 50 and attach it to the adapter 59, and then insert this adapter 59 into the stationary VTR 60 in which the television 53 and the signal line 64 are preliminarily connected. The read signal is the head amplifier 63 and the reproduction circuit 61.
Sent to and played on TV 53.

On the other hand, as mentioned above, the cassette is downsized and the camera integrated VT
Not only has the R been made smaller and lighter, but the components of the camera-integrated VTR have also been made smaller and lighter. In particular, the motor of the VTR mechanism has a large proportion in weight and volume, and is being greatly downsized. As a result, the efficiency of the motor is deteriorated, a large output is not output under a limited voltage, and the rotation speed of the motor corresponding to the generated load has to be set low. On the other hand, there is also a tendency to reduce the voltage used in the device for power saving. For this reason, the voltage applied to the motor has to be lowered, which causes a limitation in the motor output.

Problems to be Solved by the Invention When it is attempted to reduce the size and weight of a camera-integrated VTR by the method of reducing the size of the above-mentioned components, especially the motor, it is necessary to divide the function and cut the tape drive speed. I had to keep it low. Therefore, the camera integrated VT
Executing the fast-forward mode in R took a lot of time, and there was a big problem in terms of usability.

Also, when using the camera-integrated VTR as a playback device,
The signal line had to be connected to the TV every time it was played, which was extremely inconvenient.

When using an adapter, it is not necessary to connect the signal line to the TV, but once the small cassette is taken out from the camera-integrated VTR, it is attached to the adapter and it is installed in the conventional stationary VT.
There was a problem that the work of inserting it in R was complicated and the adapter was expensive.

In addition, even if a smaller cassette is used than the standard cassette, it is necessary to attach it to an adapter or to mount it on a stationary VTR and reproduce the signal using the magnetic head of the stationary VTR, so that the cassette is drastically reduced. It was difficult to miniaturize, and there was a limit to miniaturization of the VTR with a built-in camera.

In view of the above-mentioned title, the present invention provides a recording / reproducing device that can substantially reduce the size and weight and the operability.

Means for Solving the Problems In order to solve the above problems, the recording / reproducing apparatus of the present invention is connected to a stationary recording / reproducing apparatus having a first head for recording / reproducing a signal on a tape wound around a first cassette. Connecting portion, a second head for recording and reproducing a signal on a tape wound around a second cassette smaller than the first cassette, a motor for driving the tape, and a battery for supplying power to the device. And a switching means for switching whether the electric power is supplied to the motor from the battery or the stationary recording / reproducing apparatus.

Furthermore, the connection of the connection portion enables a signal to be exchanged with the stationary recording / reproducing apparatus, and a housing portion for housing the apparatus body is integrally provided in a part of the housing, and the inside of the housing portion is provided. The stationary recording / reproducing apparatus is provided with a connecting portion for connecting to the connecting portion of the main body of the apparatus so that connection and disconnection can be freely performed.

The present invention has the above-described configuration, and when the recording / reproducing apparatus is connected to the stationary recording / reproducing apparatus, the switching unit causes the stationary recording / reproducing apparatus to generate a predetermined voltage higher than the voltage supplied from the battery to the motor. Even if the motor used in the recording / reproducing apparatus is drastically reduced in size and weight, by connecting to the stationary recording / reproducing apparatus, it is possible to realize a practically sufficient speed in the fast-forward mode of the tape.

Further, since the reproducing apparatus is connected to the stationary recording / reproducing apparatus, there is no need to connect signal lines, and usability is greatly improved. Further, since the small cassette is not mounted on the stationary recording / reproducing apparatus, there are few restrictions on the setting of the shape of the cassette, and the size can be significantly reduced as compared with the conventional one.

Therefore, detailed description will be omitted.

30 is a recording / reproducing circuit, and if necessary, a stationary VTR20
Recording / playback processing of signals from the VTR1, small-camera integrated VTR1 and stationary VTR20 signals from the small-camera integrated VTR

Reference numeral 31 is a television, which is constantly connected to the stationary VTR 20 by a signal line 32 to exchange signals.

Next, each operation will be described with reference to the drawings. First, as is well known, recording by the camera unit 2 of the VTR 1 with a small camera is performed by processing the output signal of the camera unit 2 by the signal processing unit 3 and supplying it to the rotary head 5 through the amplifier unit 4 to record it on the magnetic tape 7. .

There is no reproduction signal processing circuit in the small camera integrated system VTR1, but when the signal recorded on the magnetic tape 7 of the small cassette 6 is reproduced by the above operation, the small camera integrated VTR1 is installed in the stationary VTR20. Store in the storage unit 33. By this storing operation, the connecting portion 14 and the connecting portion 34 are connected, and the small camera integrated VTR 1 and the recording / reproducing circuit 30 are mechanically and electrically connected. The switch 11 turns on the contact 12a in response to a command from the power supply switching means 13
Connected with 9. On the other hand, since the contact 27a of the reproduction changeover switch 26 is turned on by a command from the reproduction changeover means 28, the recording / reproducing circuit 30 is connected to the amplifier section 4, and the rotary head 5 is connected to the rotary head 5 by operating an operation section (not shown). The wound magnetic tape 7 runs, and the magnetic tape 7 of the rotary head 5 runs.
The signal reproduced by the above scanning is processed by the recording / reproducing circuit 30 and sent to the television 31. At this time, the voltage of the capstan motor 8 that drives the magnetic tape 7 can be set to a necessary and sufficiently high voltage, so that a sufficiently fast speed can be realized in the fast-forward mode or the fast-forward reproduction mode.

For reproduction of the signal recorded in the standard cassette 21 of the stationary VTR 20, if the small camera integrated VTR 1 is taken out from the storage section 33 and the connection section 14 and the connection section 34 are removed, the reproduction changeover switch 26 turns on the contact 27b. Therefore, the recording / reproducing circuit 30 is connected to the amplifier section 24, and the magnetic tape wound around the rotary head 22 by the operation of the operation section (not shown).
The signal 23 reproduced by scanning the magnetic tape 23 of the rotary head 22 is processed by the recording / reproducing circuit 30 and sent to the television 31.

The recording of the signal to the standard cassette 21 in the stationary VTR 20 is in the same state as in the case of the above-mentioned reproduction.
Since 27b is in the ON state, the signal of the television 31 is processed by the recording / reproducing circuit 30 and is sent to the rotary head 22 via the amplifier section 24 so that it is recorded on the magnetic tape 23.

Next, the signal reproduced by the stationary VTR 20
The case of recording in TR1 will be described. At this time, the compact camera integrated VTR 1 is stored in the storage portion 33 of the stationary VTR 20, and the connection portion 14 and the connection portion 34 are connected,
The regeneration changeover switch 26 of the stationary VTR 20 has the contact 27a turned on as indicated by the solid line, and the changeover switch 25 is also turned on as indicated by the solid line. Then, the recording / pause mode is instructed to the small camera integrated VTR 1 by an operation unit (not shown), and the operation mode (not shown) is operated to the stationary VTR 20 to instruct the reproduction mode. Rotating head 22
The signal reproduced by is switched from the amplifier 24.
It is input to the recording / reproducing circuit 30 via 25. This record
The signal is processed by the playback circuit 30, one is output as a monitor signal to the TV 31, and the other is FM as a recording signal.
From the playback selector switch 26 to the connection 3 in the modulated state
4, input to the amplifier unit 4 via the connection unit 14. TV 3
When the desired position is confirmed from the monitor 1 of 1, the recording pause mode of the VTR1 with a small camera is released, and when the recording mode is set, a signal is input from the amplifier section 4 to the rotary head 5 and recorded on the magnetic tape 7. To be done.

At this time, since the connection unit 14 and the connection unit 34 are connected to each other so that a control signal is transmitted and received between the control circuit 16 of the small camera integrated VTR 1 and the control circuit 36 of the stationary VTR 20, recording is performed. If the position is specified, the operation of the stationary VTR20 and the operation of the compact VTR1 with a built-in camera are linked, and the operation of the stationary VTR20 (not shown) is performed once and the stationary VTR20 is regenerated and compact. Needless to say, it is possible to instruct the recording operation of the camera-integrated VTR1 and the stop operation of the stationary VTR20 and the temporary recording operation of the compact camera-integrated VTR1 to improve the operability.

Next, the playback signal of the compact camera integrated VTR1 is transferred to the stationary VTR20.
The operation of recording will be described. Small camera integrated VT
The reproduction operation of R1 is as described above. Stationary VTR2
The recording pause mode is indicated on 0 by an operation unit (not shown), and the operation unit (not shown) is provided on the compact camera integrated VTR 1.
To specify the playback mode. The signal reproduced by the rotary head 5 is input to the recording / reproducing circuit 30 of the stationary VTR 20 as described above. The input signal is processed, one is output as a monitor signal to the television 31, and the other is input to the amplifier section 24 via the changeover switch 25 in a state of being FM-modulated as a recording signal. When the desired position is confirmed on the monitor of the TV 31, if the recording pause mode of the stationary VTR 20 is canceled and the recording mode is set, the amplifier section
A signal is input to the rotary head 22 from 24 and recorded on the magnetic tape 23.

At this time, since the connection unit 14 and the connection unit 34 are connected to each other so that a control signal is transmitted and received between the control circuit 16 of the small camera integrated VTR 1 and the control circuit 36 of the stationary VTR 20, recording is performed. If the position is specified, the operation of the compact camera integrated VTR1 and the stationary VTR20 can be linked, and the small camera integrated VTR1 can be operated by one operation of the operation unit (not shown) of the small camera integrated VTR1.
Playback operation and recording operation of the stationary VTR20, stop operation of the compact camera integrated VTR1 and recording pause operation of the stationary VTR20 can be instructed, and it is possible to improve the operability by improving the reproduction signal of the stationary VTR20. This is the same as when recording with a compact camera integrated VTR1.

When the end detection means 15 detects the end of the magnetic tape 7, the end detection signal is input to the control circuit 16 and the control circuit 16
By this operation, the mode of the VTR1 with a compact camera is switched to the stop mode. On the other hand, since the control circuit 16 is connected to the control circuit 36 of the stationary VTR 20 by connecting the connection portion 14 and the connection portion 34, the output of the control circuit 16 is input to the control circuit 36 and the stationary VTR 20 is instructed by the control circuit 36. Is switched to the recording pause mode. Therefore, the recording time of the small cassette 6 is shorter than that of the standard cassette 21, and even when the plurality of small cassettes 6 are collectively recorded in the standard cassette 21 of one roll, the compact camera integrated VTR 1 is in the stop mode. It is only necessary to replace the small cassette 6 and the recorded signal does not have a break, and dubbing can be continued easily.

EFFECTS OF THE INVENTION With the above configuration, when the morphological recording / reproducing apparatus is connected to the stationary recording / reproducing apparatus, the predetermined voltage higher than the voltage supplied from the battery to the motor is provided by the switching means by the stationary recording. Even if the motor that is applied from the playback device and used in the recording and playback device is made significantly smaller and lighter,
By connecting to the stationary recording / reproducing apparatus, the mode of fast-forwarding the tape in the actual reproducing operation can be realized at a speed practically sufficient, and the size and weight can be reduced without sacrificing the operability.

Further, since it is only necessary to connect the portable recording / reproducing apparatus directly to the stationary recording / reproducing apparatus, there is no need to connect signal lines,
Also, since there is no need for an adapter, it becomes possible to handle the cassette as if it were mounted on a stationary recording / reproducing apparatus, which greatly improves usability.

Further, the portable recording / reproducing apparatus only needs to be provided with a head amplifier section for amplifying the signal from the head, and the reproducing process uses the reproducing circuit of the stationary recording / reproducing apparatus.
It is possible to reduce the size and weight of the portable recording / reproducing device and reduce the cost.

Moreover, the recording time of the small cassette used in the portable recording / reproducing apparatus is shorter than that of the standard cassette by detecting the end of the tape in the portable recording / reproducing apparatus, and a plurality of small cassettes are collectively recorded in one standard cassette. This is very convenient, but even in this case, if the VTR1 with a small camera is in the stop mode, you can replace the small cassette, and the recorded signal will not break and you can continue dubbing easily. .

In addition, by connecting the portable recording / reproducing apparatus and the stationary recording / reproducing apparatus to each other, the control signals are transmitted / received and their operations are interlocked, so that the operability can be greatly improved.

Furthermore, since the small cassette itself is not installed in the stationary recording / playback device, there are few restrictions on the setting of the shape of the cassette, and it is possible to make it much smaller than before. The device can likewise be significantly smaller.
