Abstract
Abstract A cartridge for a dye-impregnated endless ribbon includes a transport device disposed within the cartridge; the transport device includes a driving member having a surface, and a stationary member having another surface so that the surfaces define a passage for the ribbon. Friction-generating devices are disposed near the surface of at least one member and in contact with the ribbon, causing the ribbon to move only in one direction through the passage. A drive device is provided and may be operated to move the driving member with respect to the stationary member.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
193 words
A cartridge including a housing for storing an endless dye-carrying ribbon in several locations in said housing, and for operatively withdrawing successive portions therefrom, said portions being arranged to be advanced in a predetermined direction from a first location to a fourth location downstream of said first location, comprising in combination: ribbon conduit means located at a second location downstream of said first location for returning and guiding the successive ribbon portions into said housing, a single unitary resilient stationary member, secured inside said housing, a single substantially rigid driven member arranged in said housing, operable to be advanced in said predetermined direction, and including two outer parts, at least one of said outer parts having a set of teeth along the periphery of said driven member, said teeth in cooperation with said stationary member engaging successive portions of said ribbon, a groove being defined between said outer parts, said members being located at a third location downstream of said second location and disposed between said second and fourth locations, said stationary member resiliently pressing said ribbon into engagement with said teeth, and an arm reaching into said groove to make contact therewith.
Claim 2
Dependent Claim
193 words
A cartridge including a housing for storing an endless dye-carrying ribbon in several locations in said housing, and for operatively withdrawing successive portions therefrom, said portions being arranged to be advanced in a predetermined direction from a first location to a fourth location downstream of said first location, comprising in combination: ribbon conduit means located at a second location downstream of said first location for returning and guiding the successive ribbon portions into said housing, a single unitary resilient stationary member, secured inside said housing, a single substantially rigid driven member arranged in said housing, operable to be advanced in said predetermined direction, and including two outer parts, at least one of said outer parts having a set of teeth along the periphery of said driven member, said teeth in cooperation with said stationary member engaging successive portions of said ribbon, a groove being defined between said outer parts, said members being located at a third location downstream of said second location and disposed between said second and fourth locations, said stationary member resiliently pressing said ribbon into engagement with said teeth, and an arm reaching into said groove to make contact therewith.
Claim 3
Dependent Claim
32 words
A cartridge as claimed in claim 1, wherein said drive means is reciprocally movable through a prearranged stroke, so as to drive said ribbon through a predetermined distance during each alternate stroke.
Claim 4
Dependent Claim
26 words
A cartridge according to claim 1, including storage means, and wherein at least a major portion of said ribbon is stored loosely in said storage means.
Claim 5
Dependent Claim
16 words
A cartridge according to claim 3, wherein said storage means include guide means for said ribbon.
Claim 6
Dependent Claim
27 words
A cartridge according to claim 1, wheein said driving member includes a ratchet mechanism for rotating the driving member so as to obtain a resultant unidirectional motion.
Claim 7
Dependent Claim
54 words
A cartridge according to claim 5, wherein said drive means are adapted to be coupled to a printing mechanism, and further comprising resilient engagement means for engaging said ratchet mechanism, and adapted to be coupled to said printing mechanism for a resultant unidirectional rotation of said driven member as commanded by said printing mechanism.
Claim 8
Dependent Claim
33 words
A cartridge according to claim 5, wherein said friction-generating means comprise a layer of elastic material mounted on the periphery of said driven member, the layer material having a high coefficient of friction.
Claim 9
Dependent Claim
15 words
A cartridge according to claim 5, wherein said driven member is composed of elastic material.
Claim 10
Dependent Claim
43 words
A cartridge as claimed in claim 5, wherein said ratchet mechanism further comprises a central portion and a plurality of leaf springs extending between said central portion and the periphery of said ratchet mechanism, whereby the periphery of said ratchet mechanism is depressible.
Claim 11
Dependent Claim
15 words
A cartridge as claimed in claim 1, wherein said resilient means is a leaf spring.
Claim 12
Dependent Claim
19 words
A cartridge as claimed in claim 1, wherein said driving member is adapted to be driven by drive means.
Claim 13
Dependent Claim
13 words
A cartridge according to claim 11, wherein said drive means are intermittently operable.
Claim 14
Dependent Claim
28 words
A cartridge according to claim 11, wherein said drive means are coupled to a printing mechanism and to transport means for transporting said ribbon towards said printing mechanism.
Claim 15
Dependent Claim
83 words
A cartridge as claimed in claim 1, wherein at least a part of said ribbon is tensionable from a normally occupied slack position, and wherein said one member is further moveable in a direction opposite to said predetermined direction, and cooperates with said ribbon conduit means, so that upon the movement of said one member in said opposite direction, said portion, due to any lack of tension being applied thereacross, is restrained from moving through said ribbon conduit means in said opposite direction.
Claim 16
Dependent Claim
21 words
A cartridge as claimed in claim 1, wherein both outer parts have a set of teeth, said teeth being zig-zag shaped.
Claim 17
Dependent Claim
25 words
A cartridge as claimed in claim 1, further including a bottom portion having an opening adapted to receive drive means for driving the driven member.
Claim 18
Dependent Claim
15 words
A cartridge as claimed in claim 1, wherein said arm is integral with said housing.
