How to prevent tape twist and loosening in video cassette recorder

摘要

The anti-twisting method of this tape is to prevent and prevent the tape in advance in the video cassette recorder. To this end, the method includes checking (201) whether a tape has been inserted on deck 14; Once the tape has been inserted, it is checked (202) whether humidity is detected on the drum from the humidity gauge mounted on the drum in the deck; If there is no humidity on the drum, check if the tape is loaded (205); If the tape is loaded through the tape loading check process 205, it is checked whether the switching pulse generated according to the rotation of the drum is normally generated (206); When the switching pulse is normally generated through the switching pulse check process 206, it is checked whether the take-up reel pulse generated by the take-up reel rotation in the deck 14 is normally generated (211); If the take-up reel pulse is normally generated, it is checked whether or not the supply reel pulse generated according to the supply reel rotation in the deck 14 is qualitatively generated (212); If the supply reel pulse is normally generated, perform the controlled mode via the provisional means as a command (213); When abnormal conditions are detected through the humidity check process 202, the switching pulse check process 206, the take-up reel pulse check process 211, and the supply reel pulse check process 212, the operation mode is stopped and the tape is removed from the deck. Controlling to eject (204) is performed.
