Abstract: A guidance system for tape in a tape cartridge includes two corner guides and an optional third guide. The two corner guides may be angled or tapered to produce a bow or slope in the tape, and to steer the tape. If provided, the third guide is readily adjustable during manufacture to an exact predetermined distance from the two corner guides, thereby avoiding problems due to build-up of manufacturing tolerances. A method of constructing such a system provides an interference fit ferrule on a pin or a nail-like pin as the third guide, such that the position of the ferrule or nail head of the pin can be adjusted to the exact position desired during manufacture.

Abstract: A film image reader/scanner apparatus providing two capabilities, operable at separate times wherein one capability provides for the projection onto a viewing screen of a light image created from a film image presented to the apparatus with the second capability providing for a line-by-line scan of the light image that is directed to a linear scan array for the production of signals representative of the light image.

Abstract: A disk cartridge for a rotatable recording disk includes a slidable shutter for providing access to the recording disk through the disk cartridge. A unique mounting for a return spring for the shutter allows the return spring to be of a maximum length which allows increased control of the forces generated by the return spring. The disk cartridge is further provided with a locking mechanism for preventing movement of the recording disk within the disk cartridge during storage.

Abstract: An electrophotographic copying apparatus includes a copying cycle which always alternates development between two image areas to equalize wear along the length of its photosensitive belt and which eliminates a cleaning cycle after the final copy of a copying cycle to reduce belt revolutions. Also included is a combined charger/precleaner to reduce size and a light image mask to prevent unnecessary toning of the belt.

Abstract: An image scanning apparatus for use in a camera or reproduction machine where a mirror reflects the image producing rays by movement relative to the object and image planes and a lens while staying on a plane, during such movement, which is coincident to the perpendicular bisector of an imaginary line connecting corresponding image points on the normal image plane and the folded image plane.
