Filed: 1985-10-02
Abstract: PURPOSE:To prevent a slip between a disk and a turntable by starting a motor, lowering the starting voltage of the motor by detecting the starting of the motor and making the rise characteristics of the motor gentle. CONSTITUTION:A Hall-element driver 5 drives a Hall element 6 by an output from a motor control section 4 receiving a starting command from a micro-computer 1. An output from the Hall element 6 is amplified by a comparison amplifying circuit 7 and transmitted over a driver 8, and a motor 2 is started by an output from the driver 8. On the other hand, the motor is started by a starting command while the clear of a flip-flop 14 is released, the flip-flop 14 is set by a starting detecting signal generated by the srating of the motor, and a switching transistor 15 is turned ON. Accordingly, the applied voltage of the Hall element 5 drops, and the rise characteristics of the motor 2 are made gentle. When the motor 2 reaches the aimed number of revolution, the switching transistor 15 is turned OFF again.

Filed: 1986-09-19
Abstract: PURPOSE:To prevent an erroneous action without fail when displaying is off by preventing the executing of a memory control when the displaying is off even when a counter memory control action is in any condition at the time of displaying a counter by an on screen display (OSD). CONSTITUTION:When the command of displaying off is inputted from the condition of a displaying on mode by an input 3, a control microcomputer controls an OSD and a displaying off condition 2 is obtained. At the mode, a memory control is not executed, and even when an input 6 is inputted to the control microcomputer, a control is executed so as to be neglected. When a command to make a displaying control input 3 into displaying on is impressed, the OSD is controlled and again, the screen is displayed. In this condition, when a memory control input 6 is executed, the memory control comes to be off, the displaying comes to be a condition 4 and the memory control action is not executed. In this condition, when the displaying control input 3 to make the displaying off is impressed, a condition 5 of the displaying off is obtained. Thus, the displaying off condition 2 does not execute the memory control and the danger of the malfunction is prevented.
