摘要： PURPOSE: To prevent deterioration in sound quality without recording/ reproduction at instable tape running speed by constituting the titled recorder that a tape running control section is not brought into reproduction mode or recording mode within a prescribed time until the tape running speed reaches a steady-state value when the tape running speed is changed over in the dubbing mode.
CONSTITUTION: When a speed changeover switch 82 included in a speed control section 8 is operated and the tape running speed of the 1st tape running section 1 and the 2nd tape running section 2 is changed over, a prescribed time generating section 9 generates a pulse being at an 'H' level for a prescribed time until the tape speed reaches a stable state. Even when the 1st tape running section is selected to the 'reproduction mode' and the 2nd tape running section to the recording mode within the prescribed time, a command from control circuits 61, 71 to the tape running sections 1, 2 is not outputted. It is outputted after a prescribed time is elapsed and the 1st tape running section 1 is brought to reproduction mode and the 2nd tape running section 2 is transited to recording mode.

摘要： PURPOSE: To improve remarkably the operability of a tape recorder by stopping automatically the running of the other tape when a shorter tape comes to its end so as to prevent useless tape running in recoding a signal on a recorded tape onto a recording tape with a different length.
CONSTITUTION: When the 1st tape 11 comes at firs;t to its end while a reproduced sound on the 1st tape 11 loaded to the 1st tape running section 1 is recorded onto the 2nd tape 22 loaded to the 2nd tape running section 2, the 1st end detection section 3 outputs an [H] signal to OR circuits 52, 63. The OR circuit 52 outputs the [H] signal to the 1st running control section 50, which brings the running mode of the 1st tape running section 1 from [reproduction] to [stop] mode. Further, the OR circuit 63 outputs an [H] signal to the 2nd running control section 60 and the 2nd running control section 60 brings the running mode of the 2nd tape running section 2 from [recording] to [recording pause] mode.

摘要： PURPOSE: To stop automatically the running of a tape running section in the reproducing state when the sound recoding state is released during dubbing by designing the titled recorder that the 1st running control section stops the running of the 1st tape running section when the 2nd control section releases the sound recording state of the 2nd tape running section during dubbing.
CONSTITUTION: Since an [H] signal is inputted to a stop input terminal of a control circuit 61 when the stop switch 63 of the 2nd running control section 6 is depressed while the reproduced sound of the 1st tape 10 loaded to the 1st tape running section 1 is sound recorded on the 2nd tape 20 loaded to the 2nd tape running section 2, a control circuit 61 brings the running of the 2nd tape running section 2 to the [stop mode]. Since the [H] signal is inputted to a stop input terminal of the control circuit 51 via an OR circuit 52 at the same time, the control circuit 51 brings the running of the 1st tape running section 1 to the [stop mode]. As a result, both the 1st tape running section 1 and 2nd tape running section 2 stop running.

摘要： PURPOSE:To reduce distortion to perform recording faithful to input signals, by controlling a gain control circuit according to the count value of output pulses of the level correction control circuit corresponding to a distortion level detector. CONSTITUTION:The sound signal which is input from terminal 1 and is caused to pass through gain control circuit 3 is converted to a DC voltage corresponding to the peak level by level detector 51 of distortion level detector 5 and is compared with the output voltage of reference voltage generator 52 corresponding to the distortion level by comparator 53. When this input signal exceeds a correct recording level, a signal corresponding to the excess is converted to pulses by AD converter 61 of level correcting circuit 6, and these pulses are counted by the second count circuit 62, and one pulse is generated when the count value reaches a prescribed value. This output pulse is input to the first count circuit 4 and enlarges the attenuation quantity of circuit 3 to restrain distortion of the recording signal. After that, when signals within the correct recording level are continuous, time set circuit 63 is connected to circuit 62, and the recording level is not changed. As a result, recording faithful to input signals can be performed.

摘要： PROBLEM TO BE SOLVED: To enhance the accuracy of reading of an information reproduced signal by providing a signal processing means which has a low-pass characteristic eliminating a high frequency component from an output signal which is obtained by measuring the fluctuation quantity on the time base of the information reproduced signal and controlling an emission intensity in accordance with the magnitude of the output signal of the signal processing means. SOLUTION: After a reflected light from an optical disk 1 is converted into an electric information signal in a conversion part 4, the fluctuation quantity on the time base of the information reproduced signal is measured in a measurement part 5. At this time, a spike shaped waveform which is to be generated when an optical beam is moved to an adjacent track and a shevron waveform which is to be generated when the beam passes a reflection abnormal area are repeated every time an optical disk makes one revolution. A driving part 7 obtains an output signal in which the amplitude of the spike shaped waveform is attenuated by passing this signal through a signal processing part 6 having the low-pass characteristic to drive a light emitting part 3 so as to control the emission intensity in accordance with the magnitude of the output signal. Thus, the reduction of a reflected light quantity in the reflection abnormal area of the optical disk 1 is compensated with the increase of the emission intensity.
