Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic recording and reproducing device, and more particularly to an automatic recording device.

Conventionally, when recording only the song you want to record for a source input from the line, press the pause switch at the end of the song, wait until the next song you want to record comes, and when that song comes, release the pause switch and record again. I used to do this manually, but I found it very difficult to record multiple songs while selecting them.

FIG. 1 shows a specific embodiment of the prior art. In the figure, record switch 131 and play switch 1
32 are pressed at the same time, the transistor 136 becomes conductive through the resistor 134, and the play plunger 121 is driven.When the recording switch 131 is pressed, the amplifier 112 is driven and the recording mode is set. When a song that is not to be recorded is input to the input terminal 111, when the pause switch 133 is pressed, the transistor 137 is turned on through the resistor 135, and the pause plunger 1 is turned on.
22 is driven, and the amplifier 112 and mechanism (not shown) record the tape 101 while maintaining the recording mode.
Stop running and wait until recording again. When the next song to be recorded is input, the user manually releases the pause switch 133 and starts recording, which is a repeated operation.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus that simplifies operations by automatically performing operations that were conventionally performed manually, and that enables automatic recording of only desired source music.

Embodiments of the present invention will be described below based on the drawings. FIG. 2 is a wiring diagram showing one embodiment of the present invention. In the figure, 111 is a recording signal input signal;
112 and 113 are amplifiers, 114 is the input signal 11
1 shows a recording head for recording a signal input to a magnetic tape 101 on a magnetic tape 101, which constitutes a well-known recording circuit. Reference numeral 120 denotes a tape running device, which includes a play plunger 121 that sets a mechanism (not shown) for running the magnetic tape 101 in a play mode, a pause plunger 122 that sets the mechanism in a pause mode, and the like. 2
11 is the recording start switch, 212 is the switch 21
1 to the recording circuit through input terminal 111.
An inter-song detection circuit 213 is connected to the inter-song detection circuit 212 and generates a pulse every time between songs. A pulse generation circuit is shown, which circuit consists of, for example, a monostable multivibrator. 214 is a pulse counter connected to the pulse generation circuit 213; 221 and 222 are set switches and address switches connected to the power supply Vcc; 223 is a song number memory circuit connected to the set switch; 224 is a song number memory circuit 223 that stores the desired song number. a track number counter connected to the address switch 222 for storing the
231 is a pulse counter 214 and a music number storage circuit 2
23 shows a comparison judgment control device connected to the plungers 121 and 122. This device compares the outputs of the pulse counter 214 and the song number storage circuit 223, and when the outputs (music numbers) match, the play plunger 121 is activated. It outputs a control signal to drive the pose plunger 122, and when they do not match, a control signal to drive the pose plunger 122 is output.

In the circuit configuration shown in FIG. 2, first check the position of the song you wish to record among the signals input to the input terminal 111, then press the address switch 222 to display the desired song number counter. After adjusting the desired song number, the set switch 221 causes the storage circuit 223 to store the song number of the desired song. Next, when the recording start switch 211 is pressed when the operation is completed, the song interval detection circuit 212, pulse generation circuit 213, and counter 214 start driving, and every time the input signal from the line becomes no signal (between songs), a pulse is generated. Generation circuit 21
3 generates a pulse, and the pulse counter 214 counts the pulse signal. Comparison judgment control device 2
31 is a music number storage circuit 223 and a pulse counter 21
It is checked whether the track numbers input from 4 match, and if they match, the play plunger 121 is driven to start recording. If they do not match, the pause plunger 122 is driven and the tape stops running. The song interval detection circuit 212, pulse generation circuit 213, and pulse counter 214 are always working, and when the song number set by the set switch 221 and the count number (music number) of the pulse counter 214 match again, the pause plunger 122 is activated. will be canceled and the mode will switch to recording mode, allowing you to repeatedly automatically record the desired song.

FIG. 3 is a wiring diagram showing another embodiment of the present invention. In the figure, 300 is a processing means such as a microcomputer (μPD546c manufactured by NEC, microcomputer)
The microcomputer has an input port 301 that receives a command signal from the keyboard 10 and an inter-song detection signal from the inter-song detection circuit 212, a memory 302 that stores the number of the set song based on the set command, and a clock 3.
CPU that operates in synchronization with the clock signal of 03
(Central Processing unit) 304 and CPU30
In response to the command of the output signal of 4, the tape running device 12
0, a track number display 400, and an output port 306 for controlling the recording amplifier 112.

In the circuit configuration shown in FIG. 3, when the automatic recording changeover switch 14 is set to the annual side, the solenoids 121, 122
It is possible to control recording playback and pause manually. At this time, the address switch 12 and set switch 13 do not accept the address display 40.
0 doesn't work either. Next, automatic recording switch 14
When switched to the automatic recording side, the signal is transmitted through the input port 301 to the CPU 304, which operates in synchronization with the signal from the clock 303. The CPU 30 indicates that the automatic recording switch 14 has been switched.
4 is detected, the music selection data in the memory 302 is cleared, and the current music number is set to the initial value Φ. Next, the CPU 304 receives input from the operation switch 11, address switch 12, and set switch 13, but the address display 400 flashes the current address in the stop mode until the input is received. When the address switch 12 is input, the current address stored in the memory is sequentially added and stored again, and the address display 400 also causes the current address to blink. When the set switch 13 is input, this information is stored in the memory 302.
The address stored and set at the same time is displayed on the address display 4.
00, the address is lit regardless of the blinking display of the current address. Only when one or more songs are set and the play recording (REC) button of the operation switch 11 is pressed at the same time, the automatic recording mode is entered.

At this time, the current value is set to the initial value Φ, and the recording amplifier 112 is driven. The CPU 304 compares whether the song number is currently set or not with the contents of the memory 302. If it is set, it controls the solenoid 121 to set the recording mode, and if it has not been set, it controls the solenoid 122 to set it to the pause mode. A signal is amplified by an amplifier 112 from an audio input terminal 111, and a non-signal is extracted by a song interval detection circuit 212 and transmitted to an input port 301.

The CPU 304 adds the current song number each time a no-signal portion is input, determines whether the current song number has been set, and repeats recording or pausing to enable automatic recording.

FIG. 4 is a flow chart that more specifically expresses the operation of the magnetic recording/reproducing apparatus based on the embodiment shown in FIG.

According to the present invention as described above, it is now possible to record only desired songs by simple key operations, which previously required complicated manual operations.
