Abstract: An ink ribbon cassette housing according to the present invention is one having a bearing means which houses a ribbon supply spool shaft (6) wound with an unused ink ribbon and a ribbon take-up spool shaft (7) for taking up a used ink ribbon, in a state that both of the spool shafts are separated from each other, and which rotatably supports drive-side shaft portions (8, 9) provided on one ends of the respective spool shafts and driven-side shaft portions (10, 11) on the other ends thereof. The ink ribbon cassette housing includes a bearing means (12/13) for said drive-side shaft portions being formed of a bearing portion which has a bearing aperture (12a/13a) formed through a side wall of the cassette housing, and a bearing means for the driven-side shaft portions has a bearing portion divided into a lower bearing plate (31/32) having a semicircular lower bearing aperture (31a/32a) and an upper bearing plate (33/34) which has a semicircular upper bearing aperture (33a/34a) and which is shifted positionally forward or backward from the lower bearing plate.

Abstract: An ink ribbon cartridge includes a detachable ink ribbon spool (2/3) which may be rotatably mounted in a lower shell (4) of the cartridge via first and second shank portions (2a,2b/3a,3b) axially projected from opposite sides of the spool (2/3). The first shank (2b/3b) is of a rod shaped configuration, and includes at least large and small circumference sections which are longitudinally spaced apart. According to such configuration, the spool (2/3) may be installed only in a compatible ink ribbon cartridge having a lower shell (4) including a first bearing member (8) formed with a first bearing groove (8a) rotatably supporting the large circumference section of the first shank (2b/3b) and having a width (B) proportional thereto. A second bearing member (20) is disposed adjacent to, and spaced apart from, the first bearing member (8). The second bearing member (20) includes a second bearing groove (20a) having a width (C) proportional to the small circumference section (22) of the first shank. A third bearing member (7) is formed at a location in said lower shell (4) opposing the first bearing member (8) such that the second shank (2a/3a) of the spool (2/3) is rotatably supported thereby. According to this, various configurations of spools and compatible lower shells may be realized which may be utilized for distinguishing between various types of ink ribbon, etc. Since a spool may only be mounted in a lower shell of compatible configuration, misassembly during manufacturing is prevented. In addition, user error, such as accidental installation of an inappropriate ink ribbon, may be reliably prevented.

Abstract: An ink ribbon cartridge (1) including a cartridge housing (2) having a first side wall (11) and a second side wall (12) opposed to each other. The cartridge housing has a pair of first engaging portions (11c) on an inside surface of the first side wall (11). A supply spool (30) and a take-up spool (40) are rotatably disposed between the first and second side walls (11,12) in spaced relation and carry an ink ribbon (50) wound thereon. The spools have first end portions (32,42) formed with flanges (33,43) and second end portions (34,44) opposed to the first end portions (32,42). The flanges (33,43) have second engaging portions (33c,43c) engageable with the first engaging portions (11c). U-shaped leaf springs (60) are disposed between the second side wall (12) and the second end portions (34,44) of the spools (30,40) and bias the first end portions (32,42) of the spools against the first side wall (11). The U-shaped leaf springs (60) include base portions (61) and annular portions (62,63) extending from the base portions (61), respectively. The base portions (61) have openings (61a) receiving the second end portions (34,44) of the spools (30,40), respectively.

Abstract: An ink ribbon cartridge for a printer according to the present invention is one in which drive side shaft portions and driven side shaft portions of a ribbon supplying spool shaft wound up with an unused ribbon and a ribbon take-up spool shaft for winding a used ribbon are rotatably received respectively by drive side bearing means and driven side bearing means of a housing formed of only a lower shell. The drive side bearing means have U-letter shaped drive side bearing portions having shaft disengagement stopping portions at opening portions into which the drive side shaft portions are inserted from the top, flange receiving portions at the outside of the bearing portions on the same plane for receiving flanges of the drive side shaft portions, and slits formed with upper portions cut off and between the drive side bearing portions and the flange receiving portions making the drive side bearing portions capable of being elastically deformed toward the slits. The driven side bearing means form U-letter shaped driven side bearing portions having shaft disengagement stopping portions at opening portions into which the driven side shaft portions are inserted from the top, and spool pushing springs located at the back of the driven side shaft receiving portions.
