Abstract: A print element band (5) supports a series of print elements (35) via chevron shaped deflectable fingers (33) for printing movement upon impact by hammers of a hammer bank (2). The fingers (33) are formed integrally of the band (5) by symmetrical V-shaped slots (31, 32) which are shaped to reduce undesirable stresses and provide for more accurate finger deflection. The shape of each V-shaped slot (31, 32) is such that the width of each finger (33) is less in regions (41) where it is attached to the rest of the band (5) than in the region (42) of the apex of the finger.

Abstract: A printer of the type including a platen, a bank of hammers extending in a straight line along and spaced from the platen and a continuous metal band of magnetizable material on which are mounted a plurality of print elements is provided with drive means for moving the band between the platen and the hammer bank and control means for controlling the movement of the band so that the print elements on the band move along the line of hammers. The band drive means includes a drive wheel located near one end of the hammer bank and means for forcing the band into close contact with the peripheral surface of the drive wheel. The means for forcing the band into close contact with the peripheral surface of the drive wheel can be a permanent magnet member located on the surface of the drive wheel. The band movement control means includes guide means for guiding the band so that it extends along the hammer bank and permanent magnet means adapted to force the band into close contact with the guide means. The guide means can be a fixed guide member located near the end of the hammer bank remote from the drive wheel and the permanent magnet means can be a permanent magnet member located on the surface of the guide member and adapted to attract the band to the guide member.

Abstract: A ribbon cartridge for an endless loop inked ribbon suitable for use with a wire matrix printer, for example, is disclosed in which the cartridge includes elongated guide members to confine the path of the loop of ribbon outside of the cartridge to a predetermined path and to allow for insertion of the cartridge into a using machine without the necessity of threading inky ribbon through fixed guides on the machinery.
