Abstract

Abstract A cartridge is provided for an endless flexible character bearing band, which is non-extendible, for use on a printer including two rotating pulleys through which the above mentioned band slides, and with adjustable center-to-center distance. The cartridge includes a housing which covers the pulleys and is expendable and retractable, at least in a direction parallel to the relative movement of the pulleys, depending on whether the pulleys move away from or towards each other. The cartridge includes means for maintaining said band flat against a portion of the inner walls of the housing, in relation to said pulleys when the outer edge of said portion is at most equal to the total length of said band and freeing said tape when the outer edge is greater than the total length of the band.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 161 words
A cartridge for an endless character bearing band, said cartridge being of a construction for normally storing a band in protected relation and for mounting the tape while still within the cartridge on spaced pulleys of a machine of the type having means for adjusting the spacing of the pulleys with the band assuming a configuration including a pair of runs joined by return portions, said cartridge comprising a casing having therein positioning means for reacting on the band for foreshortening the band and temporarily increasing the spacing between the runs thereof to facilitate the readily positioning of the band over the machine pulleys, said positioning means including a movable portion disposed adjacent one of the band return portions whereby when the cartridge is associated with the machine for the placing of the band thereon and the pulleys of the machine are moved apart, the band will be automatically grasped by the pulleys and completely drawn away from said positioning means.
Claim 2
Dependent Claim 161 words
A cartridge for an endless character bearing band, said cartridge being of a construction for normally storing a band in protected relation and for mounting the tape while still within the cartridge on spaced pulleys of a machine of the type having means for adjusting the spacing of the pulleys with the band assuming a configuration including a pair of runs joined by return portions, said cartridge comprising a casing having therein positioning means for reacting on the band for foreshortening the band and temporarily increasing the spacing between the runs thereof to facilitate the readily positioning of the band over the machine pulleys, said positioning means including a movable portion disposed adjacent one of the band return portions whereby when the cartridge is associated with the machine for the placing of the band thereon and the pulleys of the machine are moved apart, the band will be automatically grasped by the pulleys and completely drawn away from said positioning means.
Claim 3
Dependent Claim 44 words
The cartridge of claim 1 wherein there are means anchoring said positioning means movable portion to said casing in said band foreshortening position thereof, said anchoring means being a type automatically releasable when said cartridge and said band are cooperatively associated with the machine.
Claim 4
Dependent Claim 64 words
The cartridge of claim 2 wherein said cartridge has means for anchoring said cartridge against transverse movement relative to one machine pulley, said positioning means movable portion has means for anchoring the same against transverse movement relative to the other machine pulley, and movement of the machine pulleys in a transverse direction effects movement of said positioning means movable portion relative to said casing.
Claim 5
Dependent Claim 68 words
The cartridge of claim 3 wherein said means for anchoring said positioning means movable portion relative to the machine other portion includes a bore for receiving a pulley component, said means for anchoring said positioning means movable portion in the band foreshortening position thereof includes a latch member interlockable within said bore, and in the positioning of said cartridge on the machine, said latch member is automatically displaced.
Claim 6
Dependent Claim 19 words
The cartridge of claim 1 wherein said tape is magnetically attractive and said band positioning means are magnetic means.
Claim 7
Dependent Claim 46 words
The cartridge of claim 5 wherein said magnet means is in the form of strip material secured partially to said casing and partially forming part of said positioning means movable portion, said positioning means movable portion further including a casing section movable relative to said casing.
Claim 8
Dependent Claim 65 words
The cartridge of claim 1 wherein the cartridge is particularly adapted to be mounted on a printer having an anvil and a cooperating hammer, one run of said band is positionable between the anvil and the print hammer of the machine, and said casing has a removable wall disposed adjacent said one band run to permit coacting of said band with the hammer and anvil.
Claim 9
Dependent Claim 42 words
A cartridge according to claim 7, characterized in that said cartridge is equipped with a protruding grip handle fitted with means for interaction with other means mounted on the printer to clamp the cartridge in place when the handle is turned down.
Claim 10
Dependent Claim 33 words
A cartridge according to claim 8 wherein said handle prevents movement of said removable wall to a position permitting operation of the printer until the handle is turned to a cartridge clamping position.
Claim 11
Dependent Claim 27 words
A cartridge according to claim 1, characterized by means on the cartridge for coding of the band for signaling to the machine the nature of said band.
