Abstract
A cartridge is disclosed in which a hub is rotatable in a housing and has its periphery partly embraced by an endless band that is mounted for travel in the housing. The band is trained about a plurality of guide rollers at least one of which is located outwardly adjacent the hub and is mounted so that it can move towards and away from the hub. Movement away from the hub is opposed by a permanently acting biasing force.
Claims14
A cartridge of the type in which strip-shaped record carriers, particularly microfilm strips, are spooled onto and off a rotatable hub, comprising a housing forming a chamber in which a hub is rotatably mounted and having an opening which communicates with said chamber for ingress and egress of a strip-shaped record carrier;
- and endless band arranged in said chamber for travel in a path in which it embraces the periphery of said hub from a first to a circumferentially spaced second location at which it respectively runs onto and off said hub, said hub being located outside the confines surrounded by said endless band travelling in said path and said band being advanced in said path in response to rotation of said hub and having two band sections which define with one another a gap for passage of said strip-shaped record carrier between said opening and said hub;
- and means mounting said band for said travel thereof, including a band-guiding element about which said band is trained and which is mounted adjacent said hub for displacement toward and away therefrom in direction substantially radially of said periphery and permanently biased in direction towards said periphery.
A cartridge of the type in which strip-shaped record carriers, particularly microfilm strips, are spooled onto and off a rotatable hub, comprising a housing forming a chamber in which a hub is rotatably mounted and having an opening for ingress and egress of a strip-shaped record carrier on an open side provided with a pivotable cover portion;
- an endless band arranged in said chamber for travel in a path in which it embraces the periphery of said hub from a first to a circumferentially spaced second location at which it respectively runs onto and off said hub, said band being advanced in said path in response to rotation of said hub;
- means mounting said band for said travel thereof, including an arm having an end portion pivoted to said housing on another end portion, a band-guiding element on said other end portion and about which said band is trained, and means biasing said other end portion with said band-guiding element towards said periphery;
- and a flexible strip member having one end secured to said housing adjacent said opening and another end secured to said other end portion of said arm.
