Abstract

PURPOSE:To attain program searching of a tape during one-touch dubbing under sound recording independently of the state of a continuous operation changeover switch by setting a motor control circuit to the individual control output state with a continuous operation control circuit. CONSTITUTION:If a one-touch dubbing button is operated when a continuous operation changeover switch S3 is turned on, a control element Q2 is cut off for a certain time by a delay means consisting of a resistance R3 and a capacitor C1, and a motor M2 is rotated. A recording/reproducing switch S4 interlocked with a sound recording tape deck is closed to the recording side automatically. A continuous operation control element Q1 is biased through a resistance R2 and is made conductive similarly to the state where the switch S3 is turned off, and rotation of the motor M2 is held.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a so-called double cassette tape recorder, which is equipped with two tape decks capable of recording and playing back, or a playback-only tape deck and a recording/playback tape deck. Configuration and its Problems In recent years, double cassette tape recorders equipped with two tape decks have become popular in order to facilitate tape editing. The main purpose of this double cassette tape recorder is to reproduce music tapes and recording tapes, so-called dubbing. In addition to this purpose, in order to effectively utilize the two tape decks, the following can be considered.That is, each tape deck is operated in a vertically continuous manner. In this operation, tape cassettes are loaded into both tape decks, one is played, the other is put into a standby state, and as soon as the tape deck in the playing state ends, the tape deck in the standby state starts. The operation is the same even if both tape decks are in recording mode. Therefore, this method is 1
By attaching the first tape cassette, you can record two tape cassettes worth of energy.

Continuous operation in a conventional double cassette tape recorder will be explained below. Figure 1 is a conventional electrical connection diagram, showing Mltd, a motor for a playback tape deck, and M2.
is the motor of the recording chip, S S is the play switch linked to the play 1-1 I 1-2 buttons on the playback tape deck, S2 is the play switch linked to the playback and recording buttons on the recording/playback tape deck, and S3 is the continuous operation. It is a changeover switch. In the conventional tape recorder constructed as described above, when the continuous operation switch S3 is turned to the OFF side, each of the chip-pick motors M1 and M2 performs a normal operation in which they can be operated individually. Next, to perform continuous operation, turn on the continuous operation switch S3, load a tape cassette into each tape deck, press the play button, and the motor M1 on the playback-only tape deck side is switched to switch 51.
-1 is supplied with power and starts operation, but motor M
2 is in a temporary state because power is not supplied. Then, in the playback-only chip, the play release tongue switches 1-1 and 1-2 are turned off at the same time as the tape ends, so that the S remoter M2 starts rotating.

However, in the above configuration, the continuous operation switch S3 is in the ON state. , ox, motor M1. like dubbing operation. An operation performed by rotating the motor M2 becomes impossible because the motor M2 does not rotate at all. -1: If you want to cue the beginning of the tape on the playback side while recording No. 48 of the first tape, it will be similarly impossible. Therefore, in any case, there is a drawback that the continuous operation switch S3 must be operated after confirming that it is OFF.Objective of the InventionThe present invention solves the above-mentioned conventional problems. To provide a double cassette tape recorder capable of one-touch dubbing and finding the beginning of a tape on the playback side while recording a source other than a tape, regardless of whether a continuous operation switch is ON or OFF.

In order to achieve the first objective of the constitution of the invention, the double power of the present invention is:
y l/tape recorder: A 1lill vertical switch circuit is provided in parallel with the continuous operation selector switch, and its control switch and circuit control the operation of the motors of both units regardless of the switching state of the continuous operation selector switch. Therefore, it is preferable to configure the output of the control circuit to be in the individual operation control output state, and it is possible to automatically control the continuous operation in a mode such as one-touch dubbing.

The operation of the tape recorder of this embodiment, which is constructed as described above, will be explained below. ,)zui,ll'l
When the service switch S3 is set to FF 1llll f/C, power is directly supplied to the motor M1 of the inner/1-deep Denoki by the motor Inochi 81-1, and the motor M2 of the recording chip is controlled by the motor switch 82. When element Q2 is cut on and another ili control element Q3 is made conductive, DC power is supplied and normal operation is performed. Next, in order to perform continuous operation from playback chip to recording/playback chip, turn the continuous operation selector switch S3 to the ON side and operate as in the conventional example [7]. -J.H.
The continuous operation control element Q1 becomes cut-off, and the resistance R
Since the control element Q2 is conductive through all of R1 and R3, the control element Q3 is cut off and no current is supplied.

The control element Q3 becomes conductive and the motor M2 starts rotating3.
Hereinafter, I- is the same as the conventional example, but the continuous operation switch, CH S3
Next, I will explain the operation to perform one-touch dubbing regardless of whether it is ON or OFF. For one-touch dubbing, 1. One button (r) is used to simultaneously playback the tape deck.

7/L-1, even if the continuous operation selector switch S3 is on the ON side, if the one-touch dubbing button is operated, the first control element Q2 of the motor M2 is activated by the delay means of the resistor R3 and the capacitor C1. It is cut off for a certain period of time, the motor M2 rotates, the recording/reproducing switch S4 linked to the recording/reproducing tape deck is automatically turned on to the recording side, and the continuous operation i18 control element Q1 turns off the continuous operation changeover switch S3. The current is biased and conductive through the resistor R2 in the same manner as in the state, and the rotation d of the motor M2 is sustained.

The purpose is achieved by bringing the motor control circuit 1 into an individual control output state using the il control circuit.

Next, a second embodiment of the present invention will be described with reference to the drawings. Figure 3 shows a control device for the motor part that allows the playback tape deck to locate the beginning of the tape while recording a one-run signal or line signal with the recording/reproduction tape deck and key.

1. This is the point that I added. The operation different from that in FIG. 2 will be explained below. With the Funk Noyon Suinochi S5 in the radio or line position, the signals from the tuning device 2 or d and the line amplifier 3 are obtained, and recording is performed using a recording/reproducing chip. In this case, even if the continuous operation changeover switch S3 is turned on, the continuous operation control element Q1 is automatically brought into conduction by the diode D1, so that recording can be performed by rotating the motor M2. In this state, to perform tape cue 7 on the playback tape deck, press the play button and FF or 1d.
By operating the REWIND button, the music selection device 1
Power is supplied to the channel selection device 1, a tape signal is input to the channel selection device 1, and when a non-track section is reached, the song selection device 1 is activated, the current of the plunger P is controlled, and the FF or RENIND button is released to enable It is what it is.

Effects of the Invention The present invention has an advantage in that by setting the morph control circuit to an individual control output state using a continuous operation control circuit, it is possible to perform one-touch dubbing and cue the beginning of a tape during recording regardless of whether the continuous operation selector switch is ON or OFF. It has several advantages.
