## Abstract

A plurality of films contained within a respective plurality of cartridges are successively spliced together and transferred to a development processing station. The leading end of a first film is drawn out from its respective cartridge and transferred to a splicer. At the splicer, a film leader is spliced to the leading end of the first film. The film leader having the leading end of the first film spliced thereto is transferred to the development processing station to cause the trailing end of the first film to arrive at the splicer. Then, at the splicer, the leading end of a second film is spliced to the trailing end of the first film. In this manner, a string of films is spliced together and transferred to the film development station, with the leading end of the first film having the film leader spliced thereto.

## Claims

### Claim 1

A film processor for transferring a plurality of films supplied from a respective plurality of cartridges to a development station for development processing, said film processor comprising:
a feed mechanism for drawing out a leading end of a first film from its respective cartridge;
a splicer for splicing a film leader to the leading end of the first film drawn out by said feed mechanism to said splicer; and
a leader transfer device for transferring the film leader having the leading end of the first film spliced thereto to the development station to cause a trailing end of the first film to arrive at said splicers;
said feed mechanism further being operable to draw out a leading end of a second film from its respective cartridge;
said splicer further being operable to splice the trailing end of the first film to the leading end of the second films; and
said leader transfer device further being operable to transfer the film leader within the film development station to cause a trailing end of the second film to arrive at said splicer;
wherein third and subsequent films among the plurality of films are successively spliced together and transferred to the development station by said feed mechanism, said splicer and said leader transfer device to form a spliced together assembly having the leader at a leading end and a string of films connected to and trailing the leader, the string of films including the first, second, third and subsequent films, an endmost of the films defining a trailing end of the assembly and not being connected to the leading end of said assembly.

### Claim 2

A film processor for transferring a plurality of films supplied from a respective plurality of cartridges to a development station for development processing, said film processor comprising:
a feed mechanism for drawing out a leading end of a first film from its respective first cartridge;
a splicer for splicing a film leader to the leading end of the first film drawn out by said feed mechanism to said splicer;
a separating device for separating a trailing end of the first film from the first cartridge; and
a leader transfer device for transferring the film leader having the leading end of the first film spliced thereto to the development station to cause a trailing end of the first film to arrive at said splicer;
said feed mechanism further being operable to draw out a leading end of a second film from its respective second cartridge;
said splicer further being operable to splice the trailing end of the first film to the leading end of the second film;
said separating device further being operable to separate a trailing end of the second film from the second cartridge; and
said leader transfer device further being operable to transfer the film leader within the film development station to cause a trailing end of the second film to arrive at said splicer;
wherein third and subsequent films among the plurality of films are successively spliced together and transferred to the development station by said feed mechanism, said splicer, said separating device and said leader transfer device to form a spliced together assembly having the leader at a leading end and a string of films connected to and trailing the leader, the string of films including the first, second, third and subsequent films, an endmost of the films defining a trailing end of the assembly and not being connected to the leading end of said assembly.
