专利汇可以提供Tape recorder专利检索,专利查询,专利分析的服务。并且PURPOSE:To prevent inadequate recording, by taking a pause state for one mechanism during dubbing to set another mechanism to the pause at the same time. CONSTITUTION:When a pause button is depressed at dubbing, a switch 29 is interlocked to be turned on and a power supply +B is applied to the base of a transistor (TR)39. The TR39 is turned on with this voltage and the 2nd motor 33 is stopped. ACG TRs 20 and 21 are turned on when the switch 29 is closed and an input signal to amplifiers 7 and 8 is muted. A capacitor 47 is charged at the same time. That is, when the pause switch 29 is turned on, the power application to the 1st and 2nd motors is interrupted and an output signal of a tape before reproduction is muted at the same time. Thus, inadequate recording when the operation both such as pause-on is performed during dubbing can be prevented.,下面是Tape recorder专利的具体信息内容。
