Title: Bearing abnormality alarm device
Inventor: SHINODA YUKIO
IPC: G11B5/52
Filed: 1977-11-18
Abstract: PURPOSE: To preliminarily discover abnormality of bearing in magnetic head or the like and to prevent deterioration of regional picture quality, by comparing the rotating amount of rotary shaft with the reference rotating amount, using time limit signal emitted in a certain time after the start or end of the driving of the rotary shaft.  
     CONSTITUTION: When the power is fed and a rotary shaft 4 is driven, at the same time, the operation of a timer unit 11 is started and rotating amount signals growing larger gradually are sent from a rotation detecting unit 9. After a certain time, when a time limit signal is delivered from the timer unit 11, said rotating amount signal is compared with the reference rotating amount signal sent out from a reference unit 10 by a comparator 12. Similarly, when the power source is cut off, rotating amount signals decreasing gradually are released from the rotation detecting unit 9 to be compared with the reference rotating amount signal. If the contact between the rotary shaft 4 and a bearing 3 is abnormal, the starting time of the rotary shaft 4 will be longer and the inertial rotation time upon stopping will be shorter. Hence, by comparing the rotating amount, an alarm is issued from an alarm device 13.
