Abstract

A strip supply magazine, known also as a cassette, having two or more exit openings, in order to provide visual indication of the type of material within the cassette. The preferred embodiment also provides an exposing and/or developing system, including interacting devices on the cassette and the holder for the cassette to control the rate of processing. The rate differs according to the position of the cassette in a holder by causing the interaction or not.

Claims

1. A cassette for the supply of film to a multiple speed printer, which printer has a cassette socket substantially rectangular in opening formation for receiving the cassette in a selected one of twO possible positions, and a speed control switch projecting into the socket;

said cassette having a shell section with a side wall and enclosing edge walls enclosing a single film coil area, two exit openings spaced from the one area with guide wall surfaces leading thereto, said guide wall surfaces being curved in opposite spiral hands so as to accept a leader web only from a coil in said cassette area positioned to loop in a regular natural curve from the coil to the opening, whereby the exit openings may be served by oppositely spiraled coils of film;

a cover to enclose said shell section; and

a switch projection on one portion only of the cassette located to contact the socket switch in only one of the two possible positions, the shell and side walls configured to avoid the switch in the other position.

2. In a film exposure and development machine having a developer tank, conveyor means including a power drive device for moving a web of photoresponsive material through the tank, said power drive device having at least two separate operative speeds, an exposure printer with conveyor means for moving a web of film through said exposure printer, an intermediate storage collector for receiving a web of film after exposure and directing the web to said developer tank at completion of exposure, the improvement of a film supply and development speed control, comprising:

a film cassette;

a cassette receiving socket for supporting said cassette on said machine;

said cassette having a central cavity for housing a coil of film web, and first and second web exit openings to provide egress for the film web;

said cassette providing a first film coil position with the coil spiraling clockwise with a leader web looping off to said first exit opening, and a second film coil position with the coil spiraling counterclockwise with a leader web looping off to said second opening;

said receiving socket having retaining means to hold said cassette positioned in a selected one of two possible positions to direct a film web emerging therefrom through one of said first and second web openings to said conveyor means of the exposure printer;

a speed controller including a switch for establishing one of two speed conditions for said power drive device; and

means carried by said cassette for influencing said switch to set up one of said conditions when the cassette is placed in said socket with the first exit opening positioned to direct the web to said exposure printer, and to set up the other condition when the cassette is placed in said socket with the second exit opening positioned to direct the web to said exposure printer.
