8. VCR Deck Operating Description 8-1 Features of Mechanism The following items describe features of the mechanism in VCR. (1) This VCR uses 3-motor system consisted of a cylinder motor, capstan motor, and loading motor. A capstan motor is used to drive the reel and the driving force is transmitted throuch the belt capstan. The cassette loading, tape loading, and mode shift operation are performed by the loading motor.
Page 131: Main Mechanism And Functions
VCR Deck Operating Description 8-3 Main Mechanism and Functions 8-3-1 Tape Path System The tape come out from the supply reel (S) of the video cassette runs through paths shown in Figs. 8-2 and 8-3, and is taken up by the take-up (T) reel. (S stands for the supply reel, and T for the take-up reel, hereafter.) At S reel side (tape enterance side of the cylinder) against the cylinder, a tension post to allow the tape surface to contact with each head with a proper tension which assures stable running, an FE head which erases entire data of the tape, and an S guide roller which restricts tape motion in upward/downward direction are provided.
Page 132 VCR Deck Operating Description 8-3-2 Reel Drive System The reel drive system consists of a capstan motor as a drive power source, belt as a power transmission mecha- nism, clutch mechanism, idle gears, and a reel disc. Selecting of forward rotation or reverse rotation is carried out by an idle gear which changes its rotating direction according to rotating direction of the clutch holder.
Page 133: Basis Of The Mechanism
VCR Deck Operating Description 8-4 Basis of the Mechanism 8-4-1 Front Loading Cassette IN (1) When a video cassette is inserted into the cassette Start Sensor OFF holder and pushed furthermore, FL arm lever is rotated by motion of the cassette holder. The rotation Microcomputer of FL arm lever makes the horizontal moving of FL drive slider.
Page 134 VCR Deck Operating Description 8-4-2 Cassette loading/unloading Modes When a cassette is entered in the VCR, the cassette is set on the reel disc by the front loading mechanism. In this case, the tension post, loading tape guide, capstan motor, and the No.9 guide are positioned inside of the tape in the cassette case.
Page 135 VCR Deck Operating Description 8-4-3 Tape Loading A full loading system is employed. In the full loading system, the tape loading starts at the same time when the cassette loading operation has com- pleted and cassette has been mounted, and the tape is pulled out, wrapped around the cylinder and the mecha- nism enters the stop status under this condition.
Page 136 VCR Deck Operating Description 8-4-5 FF/REW Modes The reels enter a free status by rotating the loading motor to go to FF/REW position. In this case, the capstan motor rotates in colck-wise direction in the REW mode. The idle gear is swung rightward or leftward according to the rotating direction of the capstan motor.
Page 137 VCR Deck Operating Description 8-4-6 Record/Playback Modes When the record or playback button is pressed, the tape is fed by the rotation of the capstan motor. In this case, a tension post touches the tape and braking froces created by the band brake linked with the tension post is applied to the S reel, thereby stabilizing the tape tension.
Page 138 VCR Deck Operating Description 8-5 System Control In the VCR, complex mechanism, video, audio, servo circuits, etc. must be operated in specified timings matched each other. The system control circuit performs entire controls for the VCR. An automatic stop function is also provided to protect important tape if a trouble occurs on the complex mecha- nism and the electrical circuits.
