How to check forward / reverse error of capstan motor in video

摘要

1. TECHNICAL FIELD OF THE INVENTION;In the VCR, the present invention relates to a method of determining an error by determining the rotational possibility of forward, reverse, and stop according to the deck mode, and comparing the rotation direction of the actual capstan motor.;2. The technical problem to be solved by the invention;When any abnormal condition occurs, the tape rotates out of the normal driving state because the rotation of the forward and reverse directions is incorrect, and the gear of the deck also has the advantage of solving the problem of the damage caused by wear.;3. Summary of Solution to Invention;According to the deck mode, it is possible to determine the rotational direction of forward, reverse, and stop, compare the actual rotation direction of the capstan motor, and if it does not match, determine the abnormal state and provide a method for transitioning the VCR to the abnormal mode (EMERGENCY).;4. Important uses of the invention;Method for checking forward / reverse rotation of capstan motor in VCR.;※ second degree of selectivity
