Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic recording and reproducing device equipped with a remote control function.

Recently, in high-end cassette-type magnetic recording and playback devices, the control buttons have been changed from the conventional lever set to a switch type in order to improve operability, and the so-called tape running mechanism is controlled by an electromagnetic device such as a plunger. The feather touch method is often used.

In this type of feather-touch method, all operations are controlled by switch operation, so remote control can be easily performed, and infrared control, which has recently been in the spotlight, allows tape running without malfunction. It can be controlled, and its ease of use can be dramatically improved by providing a remote control function.

By the way, in magnetic recording and playback devices, the recording key is generally not locked independently to prevent erroneous recording.
It is configured to be locked into recording mode or recording standby mode when operated simultaneously with the play or pause key, and can be set to recording mode or recording standby mode without any problem when operating the magnetic recording/playback device itself. However, there will be a problem if you use remote control to put it into recording mode or recording standby mode.

In other words, since it is not possible to transmit two control signals at the same time from the transmitter of the remote control device, after operating the recording key of the transmitter and transmitting the recording control signal, the recording mechanism of the magnetic recording and reproducing device is activated. , even if you try to enter recording mode or recording standby mode by operating the play or pause key,
By the time the play or pause key is operated, the recording key signal has already disappeared, the recording mechanism has recovered, and the recording mode or recording standby mode cannot be set.

Therefore, the present invention has been made in view of the above drawbacks.

The present invention provides a magnetic recording and reproducing device equipped with a remote control function configured so that it can be set to a recording mode or a recording standby mode simply by operating a recording key on a transmitter.

Embodiments of the present invention will be described below with reference to the drawings.

1.2.3 are operation keys for play, recording, and pause provided on the main body side of the magnetic recording/playback device, and when the husband operates the keys, the play mechanism 5, the recording mechanism 6, and the pause mechanism 7 are activated from the control circuit 4. It is configured to generate a control signal to control the mode and to be set in each mode.

On the other hand, the remote control device is composed of a transmitter 8 and a receiver 9, and the transmitter 8 is provided with play, record, and pause keys 10, 1L12, respectively, corresponding to the operation keys on the main body, and the oscillator 13 can be activated by operating each key. It is configured to oscillate control signals of different frequencies and drive the infrared light emitting diode 14, so that each key emits infrared light of a different frequency.

The receiver 9 then has a PIN photodiode 15 that receives an infrared control signal from the transmitter 8, and discriminates the control signal received by the diode, and outputs a control signal 81 for each mode.
Each mode control signal output S, ~S3 is composed of a discrimination circuit 16 that generates ~S3, and each mode control signal output S, ~S3 is a switching transistor 17, 18 connected in parallel with the operation keys 1, 2, 3 on the main body side.
, 19 is applied to the base electrode.

Furthermore, the recording mode control signal output S2 is connected to the delay circuit 20 and O
The signal is applied to the pause switching transistor 19 via the R gate 21.

It should be noted that operation keys such as fast forward, rewind, and stop are naturally provided, but they are not particularly shown in one drawing.

Next, the recording mode or recording standby mode operation of the present invention having such a configuration will be explained.

First, to set the recording standby mode using the operation keys of this system,
If the pause key 3 is operated while the recording key 2 is operated, the recording mechanism 6 and the pause mechanism 7 are driven and the recording standby mode is set.

Since it is in a pause state at this time, the tape is not running and the recording level can be adjusted in this state.

Then, by operating the play key 1, the play mechanism 5 is driven, and the tape starts running to record.

Incidentally, if the play key 1 is operated while the recording key 2 is in the operating state, the recording state can be immediately set.

Next, the recording mode setting by the remote control device will be explained.

At this time, the recording mode can be set simply by operating the recording key 11 of the transmitter 8.

That is, the recording key 11 of the transmitter 8 is operated, and the P of the receiver 9 is
When the control signal is received by the IN photodiode 15, the recorder mode control signal S2 is output from the discrimination circuit 16, and the switching transistor 18 is made conductive, whereby the recording mechanism control signal is generated from the control circuit 4 and the recording mechanism 6 is activated. activated.

That is, the state is the same as when the recording key 2 on the main body side is operated.

Next, the recording mode control signal S2 is ORed with the delay circuit 20.
As shown in FIG. 3, it is converted into a signal S4 delayed by a time T through the gate 21, and applied to the pause switching transistor 19, thereby activating the pause mechanism 7 and setting the recording standby mode.

When starting recording, by operating the play key 10 of the transmitter 8, the play mechanism 5 can be activated in the same manner as described above to start recording.

In addition, in the above implementation, the pause signal is generated and the recording standby mode is set by simply operating the record key on the transmitter, but if the configuration is as shown in Fig. 4, delayed play can be canceled by simply operating the record key 11. Since the signal S4 can be generated, it is also possible to start recording immediately.

As mentioned above, the magnetic recording and reproducing device of the present invention is equipped with a remote control function, and when a control signal is received by the recording key operation on the transmitter side, the receiver side generates a delayed pause based on the recording pedestal signal. This device is configured to generate a signal or play signal to set the recording standby mode to the recording mode, and is extremely useful as it enables remote control of magnetic recording and playback devices in which the recording key is not locked independently. be.
