Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a recording and reproducing apparatus such as a video tape recorder (hereinafter referred to as a VTR), and particularly to miniaturization thereof.

BACKGROUND OF THE INVENTION In recent years, in VTRs that record video and audio on magnetic tape using a rotating magnetic head, devices have been integrated with a television camera so that information obtained through the television camera can be recorded (camera-integrated VTR). is rapidly becoming popular.

Since such a camera-integrated VTR is often used for a considerable length of time while being carried, it is necessary to make it smaller and lighter. One method for this purpose is to use a camera-integrated VTR that uses a smaller cassette tape that is compatible with the cassette tape conventionally used in stationary VTRs.

As shown in FIG. 3, in a camera-integrated VTR 50 using a small cassette 55, a signal from a camera section 56 is processed by a signal processing section 57, and then passed through an amplifier section 58 that amplifies or performs head switching to a rotary head 49. The information is recorded on the magnetic tape 48 by the following steps. If you want to reproduce this signal, use this camera-integrated VTR50.
The camera is equipped with a reproduction circuit 51 and a reproduction operation section 52, and a signal line 54 is connected to the television 53 to create a camera-integrated VTR 5.
0 itself as a player, or as shown in FIG. 3, a stationary VTR 60 using a standard cassette 65.
An adapter 59 is used to attach the small cassette 55 to the camera (for example, "Television Technology" January 1986 issue PPB7-91).
Take out the small cassette 55 from the TR50 and attach the adapter 5.
9, and then attach this adapter 59 to the TV 53 in advance.
By connecting the signal 'a64 and inserting it into a stationary VTR 60, the signal read through the rotary head 62 is sent to the amplifier 63 and the reproduction circuit 61 and reproduced on the television 53.

On the other hand, as mentioned above, the cassette can be made smaller and the camera can be integrated into V.
In addition to making the TR smaller and lighter, it also features a camera-integrated VT.
Progress has also been made to make each component of R smaller and lighter. In particular, motors in the mechanical parts of VTRs account for a large proportion of the weight and volume, and are being significantly downsized. As a result, the efficiency of the motor deteriorates, and a large output cannot be produced under a limited voltage, and the rotation speed of the motor must be set low to accommodate the generated load. On the other hand, there is also a trend to lower the voltage used by devices in order to save power. For this reason, the voltage applied to the motor has to be lowered, causing a limit to the motor output.

Problems to be Solved by the Invention If an attempt is made to reduce the size and weight of a camera-integrated VTR by miniaturizing the above-mentioned components, especially the motor, it is necessary to reduce the tape drive speed in terms of functionality. had no choice but to keep it low. Therefore, executing the fast forward mode on a camera-integrated VTR takes a considerable amount of time, posing a major problem in terms of usability.

Furthermore, when using a camera-integrated VTR as a playback device, the signal line must be connected to the television each time playback is performed, making it extremely inconvenient to use.

When using an adapter, there is no need to connect the signal line to the TV; however, it is necessary to first remove the small cassette from the camera-integrated VTR, attach it to the adapter, and then insert it into a conventional stationary VTR. There were problems in that it was complicated and the adapter was expensive.

In addition, even though a cassette is smaller than a standard cassette, the size of the cassette is considerably larger due to the need to attach it to an adapter and the need to attach it to a stationary VTR and reproduce the signal using the stationary VTR's magnetic head. It was difficult to miniaturize the camera, and there were limits to miniaturization of the camera-integrated VTR.

In view of the above-mentioned title, the present invention provides a recording and reproducing apparatus that can substantially achieve both compactness and weight reduction and operability.

Means for Solving the Problems In order to solve the above problems, the recording and reproducing apparatus of the present invention is connected to a stationary recording and reproducing apparatus having a first head for recording and reproducing signals on a tape wound on a first cassette. a second head for recording and reproducing signals on a tape wound on 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 power is supplied to the motor from the battery or from the stationary recording/reproducing device.

Furthermore, the configuration is such that signals can be exchanged with the stationary recording/reproducing device by connecting the connection portion, and a storage portion for storing the main body of the device is integrally provided in a part of the housing, and the storage portion This is a stationary type recording and reproducing apparatus that is provided with a connecting part for connecting to a connecting part of the main body of the apparatus, and is configured so that it can be freely connected and disconnected.

According to the present invention, with the above-described configuration, when the recording/reproducing apparatus is connected to a stationary recording/reproducing apparatus, the switching means causes the motor to receive a predetermined voltage higher than the voltage supplied from the battery from the stationary recording/reproducing apparatus. Even if the motor used in the recording/reproducing apparatus is significantly reduced in size and weight, by connecting it to a stationary recording/reproducing apparatus, it is possible to achieve a practically sufficient speed in a tape fast-forward mode.

Furthermore, since the playback device is directly connected to the stationary recording and playback device, there is no need to connect signal lines, and the usability is greatly improved. Furthermore, since the small cassette is not attached to a stationary recording/reproducing device, there are fewer restrictions on setting the shape of the cassette, and it is possible to achieve a significant reduction in size compared to the past.

R20 signal recording and playback processing, small camera integrated VT
Reproduction processing of R1 signals and signal processing when recording signals from a stationary VTR20 on a small camera-integrated VTR1, and vice versa.
Signal processing is performed when recording on 20.

The control circuit 36 is a control circuit for switching the operation mode of the stationary VTR 20, and is particularly suitable for small camera-type VTRs.
When the detection signal from the end detection means 15 of No. 1 is input, a command is given to the stationary VTR 20 to enter the recording-time stop mode.

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

Next, each operation will be explained with reference to the drawings. First, recording by the camera unit 2 of the compact camera-integrated VTR 1 is performed by converting the output signal of the camera unit 2 into the signal processing unit 3.
The signal is then processed through the amplifier section 4 and supplied to the rotary head 5 to be recorded on the magnetic tape 7.

Although the small camera-integrated VTR 1 does not have a reproduction signal processing circuit, when the signal recorded on the magnetic tape 7 of the small cassette 6 is to be played back by the above operation, the small camera-integrated VTR 1 is connected to the stationary VTR 20. It is stored in the storage section 33. By this storage 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 1) closes the contact 12 in response to a command from the power switching means 13.
a is turned on and connected to the power supply section 29. On the other hand, since the contact 27a of the playback switch 26 is turned on in response to a command from the playback switch 28, the recording/playback 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 signal reproduced by the scanning of the magnetic tape 7 by the rotating disk 5 is processed by the recording/reproducing circuit 30 and sent to the television 31.
will be sent to. At this time, the voltage of the capstan motor 8 that drives the magnetic tape 7 can be set to a sufficiently high voltage, so that a sufficiently high speed can be achieved in the fast-forward mode or fast-forward playback mode.

To reproduce the signal recorded on the standard cassette 21 in the stationary VTR 20, the small camera-integrated VTR 1 is placed in the storage section 3.
3 and remove the connection part 14 and the connection part 34, the contact 27b of the playback changeover switch 26 will be in the ON state, so the recording/playback circuit 30 will be connected to the amplifier part 24, and the operation part (not shown) will be connected. The magnetic tape 23 wound around the rotary head 22 runs by this operation, and the signals reproduced by the scanning of the magnetic tape 23 by the rotary head 22 are processed by the recording/reproducing circuit 30 and sent to the television 31. .

Recording of signals on the standard cassette 21 in the stationary VTR 20 is performed in the same manner as in the case of reproduction described above.
When recording the signal No. 1, the contact 27b of the playback selector switch 26 is in the on state, so the signal from the television 31 is processed by the recording/playback circuit 30, and the signal from the amplifier section 2
4 to the rotary head 22 to be recorded on the magnetic tape 23.

Next, a case will be described in which a signal reproduced by the stationary VTR 20 is recorded on the compact camera-integrated VTR 1. At this time, the small camera-integrated VTR 1 is stored in the storage section 33 of the stationary VTR 20, and the connection section 14 and the connection section 34 are connected, so the playback switch 26 of the stationary TR 20 is indicated by a solid line. As shown, the contact 27a is in the on state, and the changeover switch 25 is also in the on state, as shown by the solid line.

Then, the small camera-integrated VTR 1 is instructed to enter the recording-time-stop mode using an operation section (not shown), and the stationary VTR 20 is instructed to playback mode by operating its operation section (not shown). The signal reproduced by the rotating head 22 is sent to the amplifier section 2.
4 to the recording/reproducing circuit 3 via the changeover switch 25.
It is input to 0. The signals are processed in this recording/reproducing circuit 30, one is output as a monitor signal to the television 31, and the other is FM modulated as a recording signal and is sent from the reproduction selector switch 26 to the connection section 34 and the connection section 14. The signal is input to the amplifier section 4 via the signal. Once the desired position is confirmed on the monitor on the television 31, the recording/stop mode of the small camera integrated VTR 1 is canceled and the recording mode is set. A signal is input from the amplifier section 4 to the rotating section 5 and the magnetic tape is rotated. 7 is recorded.

At this time, since the connection part 14 and the connection part 34 are connected to send and receive control signals between the control circuit 16 of the small camera-integrated VTR 1 and the control circuit 36 of the stationary VTR 20, recording is not possible. If you specify the position, stationary VT
The operation of the R20 and the operation of the compact camera-integrated VTR 1 are linked, and a single operation of the stationary VTR 20's operation unit (not shown) can perform the playback operation of the stationary VTR 20, the recording operation of the compact camera-integrated VTR 1, and the stationary Needless to say, it is possible to instruct the stop operation of the VTR 20 and the recording-time operation of the compact camera-integrated VTR1, thereby further improving operability.

Next, the playback signal of the small camera-integrated VTR1 is transferred to the stationary VTR1.
The operation of recording on the TR 20 will be explained.

The playback operation of the small camera-integrated VTRI is as described above. For the stationary VTR 20, the recording/stop mode can be instructed using an operation panel (not shown), and the compact camera-integrated VT
The user operates the operation section (not shown) of R1 to instruct the playback mode. The signal reproduced by the rotating lid 5 is input to the recording/reproducing circuit 30 of the stationary VTR 20 as described above. The input signals are processed, and one is outputted to the television 31 as a monitor signal, and the other is FM modulated and input to the amplifier section 24 via the changeover switch 25 as a recording signal. When the desired position is confirmed by monitoring on the television 31, the stationary VTR 20 is released from the recording-time stop mode and set to the recording mode, and a signal is input from the amplifier unit 24 to the rotary head 22 and recorded on the magnetic tape 23. recorded.

At this time, since the connection part 14 and the connection part 34 are connected to send and receive control signals between the control circuit 16 of the small camera-integrated VTR 1 and the control circuit 36 of the stationary VTR 20, recording is not possible. By specifying the position, the operation of the compact camera-integrated VTR 1 and the stationary VTR 20 will be linked,
A single operation of the operation unit (not shown) of the compact camera-integrated VTR 1 can cause the playback trajectory of the compact camera-integrated VTR 1 and the recording operation of the stationary VTR 20, as well as the stop operation of the compact camera-integrated VTR 1 and the recording of the stationary VTR 20. - The fact that a stop operation can be instructed and the operability can be further improved is the same as when recording the playback signal of a stationary VTR 20 with a small camera-integrated VTR 1.

When the end detection means 15 detects the end of the magnetic tape 7, an end detection signal is input to the control circuit 16, and the mode of the small camera-integrated VTRI is switched to the stop mode by the operation of the control circuit 16.

On the other hand, since the control circuit 16 is connected to the control circuit 36 of the stationary VTR 20 through the combination of the connection part 14 and the connection part 34, the output of the control circuit 16 is input to the control circuit 36, and the commands from the control circuit 36 cause the stationary VTR 20 to be connected to the control circuit 36. is switched to record-time stop mode. Therefore, the recording time of the small cassette 6 is shorter than that of the standard cassette 21, and even when a plurality of small cassettes 6 are recorded on one roll of the standard cassette 21, the small camera-shaped VTR 1 is in stop mode. If necessary, the small cassette 6 can be replaced, and there will be no breaks in the recorded signal, making it easy to continue dubbing.

Effects of the Invention With the above configuration, when the portable recording and reproducing device is connected to the stationary recording and reproducing device, the switching means switches the predetermined voltage higher than the voltage supplied from the battery to the motor to the stationary recording and reproducing device. Even if the motor that receives the power from the playback device and is used in the recording and playback device is significantly smaller and lighter,
By connecting it to a stationary recording/playback device, it is possible to achieve a tape fast-forwarding mode during actual playback operations at a speed sufficient for practical use, and it is possible to achieve a reduction in size and weight without sacrificing operability.

In addition, since you only need to connect the portable recording and reproducing device directly to the stationary recording and reproducing device, there is no need to connect signal lines.
Furthermore, since there is no need for an adapter, it becomes possible to handle the cassette as if it were attached to a stationary recording/reproducing device, greatly improving usability.

In addition, the portable recording/playback device only needs to be equipped with a head amplifier section that amplifies the signal from the head (since the playback process uses the playback circuit of the stationary recording/playback device,
It becomes possible to make portable recording and reproducing devices smaller, lighter, and lower in cost.

Furthermore, when detecting the end of a tape in a portable recording/playback device, the recording time of a small cassette used in a portable recording/playback device is shorter than that of a standard cassette, and multiple small cassettes are recorded together into one standard cassette. This is very convenient, but in this case as well, all you have to do is replace the small cassette when the compact camera-integrated VTR 1 goes into stop mode, and there will be no break in the recorded signal, making it easy to continue dubbing. .

Furthermore, by connecting a portable recording/reproducing device and a stationary recording/reproducing device, control signals can be exchanged and their operations can be linked, thereby greatly improving operability.

Furthermore, since the small cassette itself is not installed in a stationary recording/playback device, there are fewer restrictions on setting the shape of the cassette, and it is possible to be significantly smaller than conventional devices. The device can also be significantly downsized.
