  • Patent number: 6935794
    Abstract: An image recording apparatus in which a photosensitive material is rewound into a magazine while maintaining a predetermined disposition. Prior to rewinding of the photosensitive material, a distance between concave portions of guide members which constitute a guide portion is set to be substantially equal to the photosensitive material width and a nipping state between a pair of pulling-out rollers is cancelled. Because the nipping state is cancelled, the photosensitive material can be displaced in a width direction. Therefore, the photosensitive material can be rewound into the magazine while maintaining the predetermined disposition, and any skew is corrected by the concave portions of the guide members.

  • Patent number: 6934109
    Abstract: A method to monitor the relative position of a magnetic tape disposed in a tape drive, where that tape drive includes a first tape reel motor and a second tape reel motor. The method provides a magnetic tape disposed on a first tape reel, and releaseably attaches the first tape reel to the first tape reel motor. The method further provides a second tape reel attached to the second tape reel motor. The method operates the first tape reel motor and the second tape reel motor to transfer the tape from the first tape reel onto the second tape reel while maintaining a running second reel rotation count. The method sets a second reel rotation count limit, and determines if the running second reel rotation count exceeds that second reel rotation count limit. If the running second reel rotation count exceeds the second reel rotation count limit, then the method discontinues operation of the tape reel motors.
