Abstract

PURPOSE:To perform automatically the reproduction and recording of only an optional part of a record with an inexpensive record player, by controlling the record player with a signal that detects the presence of a reproduced signal of the record player. CONSTITUTION:The number of pieces of music to be reproduced is previously set by means of a program switch 8 of a detecting circuit 6, then confirmed by a display 9. A detecting circuit 6 detects the presence of the music part of the reproduced signals and decides a soundless part as a soundless groove between a music and a music. When the play of the set number of musics is ends, a signal is delivered from a muting control output terminal 7 to actuate a muting circuit 3. Thus the output of reproduced sounds is inhibited. Then a signal is delivered from a record player control output terminal 10 to reset automatically the tone arm of a record player 12 to be controlled to the arm rest position. Then the music play is set in the over state or the tone arm is set in the cue state.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a record playing device, which detects silent parts between songs based on the playback signal of the record playing device, and stops the record playing device after playing a pre-specified number of songs. This is linked to the recording device so that after a specified number of songs have been recorded, the recording device can be put into a recording pause state or a stopped state.

Conventionally, when trying to play or record any part or all of one side of a record, there have been two methods: manually operating the record playing device or recording device while listening to the playback sound, and automatic playback using light, etc. There is a method of controlling a record playing device by detecting the silent part of the groove of a record. However, the former method is entirely manual and requires a person to be near the record playing device at all times, which is very cumbersome.

Furthermore, in the latter method, the configuration of the record playing device is complicated and expensive, and furthermore, the recording device cannot be automatically controlled.

The present invention solves these conventional drawbacks, and makes it possible to easily play any part of a record using the output signal of a record playback device and simultaneously record it on a recording device at a relatively low cost and without using any special optical components. The purpose of the present invention is to provide a record playing device that can perform the following functions.

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

The figure is a block diagram showing an embodiment of the present invention, in which 1 is a cartridge, 2 is a reproduction equalizer, 3 is a muting circuit, 4 is an audio output terminal, 6 is an input of a detection circuit, 6 is a detection circuit, and 7 is a muting circuit. 8 is a program switch, 9 is a display, 10 is a record player control output terminal, 11 is a recording device control output terminal, 12 is a controlled record player, and 13 is a controlled recording device.

Next, the operation will be described. The signals reproduced by the cartridge 1 have their frequency characteristics compensated by the equalizer 2, and are outputted from the audio output terminal 4 via the muting circuit 3. Reference numeral 6 denotes a circuit for detecting the presence or absence of a music portion of the reproduction signal of a record used in the present invention, and this detection circuit can set the number of songs to be reproduced in advance by means of a program switch 8.

The number of set songs can be checked on the display 9, and during the performance, it is displayed how many songs are left before stopping.

When a record is played, the detection circuit 6 detects the presence or absence of a musical part in the playback signal, and determines that the silent part is a silent gap between songs, and when the preset number of songs has been played. , outputs a signal from the muting control output terminal 7, operates the muting circuit 3, and prevents reproduction sound from being output. At the same time, a signal is output from the record player control output terminal 10, and the tone arms of the 12 controlled record players are automatically returned to the armrest position, and the rotation of the turntable is stopped and the performance is ended, or the tone is automatically turned off. Set the arm to the key position 1111:1.

In addition, a signal is sent from the recording device control output terminal 11 to interlock with the controlled recording device 13, and when the preset number of songs has been played, the signal automatically returns the recording device to the previous recording state. to enter the recording pause or stop state.

As described above, according to the present invention, by controlling the record player using a signal that detects the presence or absence of a playback signal of the record playing device, it is possible to play only an arbitrary song on the record, and furthermore, by controlling the record player using a signal that detects the presence or absence of a playback signal of the record playing device, it is possible to play only an arbitrary song on the record. Any song can be recorded by controlling a recording device that records the signal from the record player using the signal. Furthermore, if the number of songs on one side of the record is set, the record playing device or recording device can be automatically stopped when one side of the record has been played or recorded, making it very convenient to use. Furthermore, the present invention provides an excellent record playing device that is relatively inexpensive since it does not require the use of special optical components, etc. as in the prior art.
