<p>PURPOSE:To prevent mis-loading of a tape by moving a post provided to a tension arm into a cover at the surrounding in case of tape loading. CONSTITUTION:In turning on a power supply of a VTR, a signal is fed to a motor drive circuit 100, a motor turns counter clockwise and a shut plate 79 shuts off the light of a photo sensor 78a. Then the signal is fed to a motor drive circuit, the motor is stopped, a pulley 71 is turned by a pulley 76, i.e., a belt 77 in this case, a screw 73a pushes a screw 74 and an arm 53 is turned. When the post 50 is hidden in a cover 80, the arm 53 is stopped and the tape is loaded. Since the post 50 is hidden in the cover 80, no possibility of mis-loading exists and the loading is executed easily.</p> |
