Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a tape recorder that uses a plurality of tracks, and is configured to simplify signal switching operations when recording a playback signal of an arbitrary track onto another arbitrary track. This relates to the signal switching method used in the tape recorder used.

In tape recorders used for language practice, etc., multiple tracks are formed on the tape and recorded on individual trunks.
By providing a repeat function, you can record the playback signal of any track to any other track, or mix the playback signals from multiple arbitrary tracks and record it to any track of the pond. There is something configured.

In a tape recorder equipped with such a multi-recording function, as mentioned above, when recording the playback signal of an arbitrary track to an arbitrary track of the recorder, it is necessary to easily and reliably switch the signals of each track circuit. is requested.

The present invention has been made in response to the above-mentioned needs, and it is an object of the present invention to provide a signal switching system for a tape recorder using multiple tracks, which simplifies the signal switching operation when performing the above-mentioned recording operation. Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 □ is a block diagram showing a signal switching system according to an embodiment of the present invention, in which -flu indicates an embodiment for a 4-track recorder, and 1 to □ indicate track recorders. 11-1■ is a recording/playback head (hereinafter referred to as a recording/playback head) corresponding to each track I~INc, 21~21V

By using the terminal voltage of the LEDs provided in Alv, 5ENI and 5ENIV, in addition to the mechanism and control circuit, head switching is performed, and recording/playback is switched based on the above-mentioned switch operation.

Also, the send switches S8 - Ss□■ in the mode selector switch section 6 are connected to a matrix circuit via attenuators 7 - 7■, and this matrix circuit is connected to the send switches of each track 1 - It is configured to apply the signals output from the ~S inch 88F, N15F, and NIV to all the recording input circuits of the track circuits other than that track via mixers 9I to 91v. Also, 5RK0SPLA on each track
The three switches S8F and N are configured so that, for example, when they are all off (released state) or all turned on at the same time (pressed state), they are in the playback state, and the indicators are configured so that they do not light up. Been,
A method is adopted that gives priority to reproduction. The three switches on each track are mechanically linked so that when one is on, the two switches are off.

A method for switching signals between tracks according to an embodiment of the present invention will be described below.

(1) When recording the playback signal of track I to track ■, the mechanism operation switch section 10 in the operation section of Fig. 3
The recording state is entered by turning on the recording switch 5PLA and the playback switch 5PLA, and the send-out switch S for track I of the mode selector switch section 6 is turned on, and the recording ENI switch S for track H is turned on. Conversely, the switches SsmJ and Sya of the mode select EOH switch section 6. ■
is turned on, and then the mechanism operation switch section 1 is turned on.
The switches SR and SPI, A of 0 may be turned on. In these recording operation states, the indicators of each switch light up.

(2) When recording the playback signals of track I and track ■ to track ■, turn on the recording switch and the playback switch of the mechanism operation switch section 10 to enter the recording state, Turn on the send switches S and S of track ■, and turn on the sound switch S of track ■. ■ Turn on. Conversely, the above switches 5SKNI and 5SIN■ of the mode selector switch section 6
and S□. (2) Turn on the switch SR of the mechanism operation switch section 10, and turn on the send switch of any track circuit from which you want to play the signal, such as 5PLA or higher, and select any track on the pond where you want to record the playback signal. By operating the mechanism operation switch section 10 to the recording state with the recording switch of the circuit turned on, signal reproduction and recording can be performed between arbitrary tracks.

” - When the playback switch in any track circuit is turned on, the playback signal of this track is simply output to the outside, and no recording is performed on any track in the reservoir when the sendout switch is off. Since the recording operation can be performed by paying attention to the switch, erroneous recording and wasteful recording can be prevented.

In addition, the mechanism operation switch section 10 is set to the recording state,
By connecting an external input source with the recording switch of any track turned on, this input source can be recorded on any of the above tracks.

As is clear from the above description, according to the present invention, in a tape recorder using a plurality of tracks, each track circuit is provided with a mode selector switch section including a recording, playback, and send switch, so that any track from which a signal is to be played can be selected. The configuration is such that recording is performed from any track to any track of the pond only when the output switch of the circuit is turned on and the recording switch of the circuit of any track of the Noh for which the playback signal is to be recorded is turned on. By switching the signal, it is possible to accurately record from any track to any track on the pond.
