In a printing device, a stationary element and a contact element for detecting an original position are respectively provided on a frame and on a gear pivotally rotating through a stepping motor. By employing an above arrangement, it is possible to easier assemble and adjust for a uniform printing quality, which is guaranteed even with a smaller size of the stepping motor.

Printing device with ribbon cassette shifting mechanism

A ribbon cartridge having a torsion spring having an improved noval contacting end for pressing the takeup spool against the drive roller, wherein the improved end holds the takeup reel against the roller in a substantially vertical position without any tilting of the takeup reel.

Ribbon cartridge

An automatic paper loading apparatus for a typewriter provided with a platen, feed rolls, and a paper bail. The paper loading apparatus essentially includes a paper alignment member pivotally mounted on a frame, a paper guide carried by a movable carriage, and three controllers, from first to third. The paper alignment member is engaged with the leading edge of an inserted printing paper while the feed rolls are spaced from the platen. The feed rolls are urged on the aligned paper and the paper alignment member is spaced from the platen for being disengaged from the leading edge of the printing paper owing to a manual operation of a lever. Upon operation of a manual member on a keyboard, the first controller drives a platen drive motor for a predetermined time duration so as to feed the paper by a predetermined amount, the second controller drives a carriage drive motor for moving the paper guide to the center portion of the printing line on the surface of the platen so as to guide the leading edge of the paper passing the printing line, and the third controller energizes a solenoid for keeping the paper bail in a position spaced from the platen while the leading edge of the paper passes between the paper bail and the platen.

Typewriter with automatic paper loading apparatus

A ribbon cartridge wherein a supply spool is continually biased so that the outer circumference of the ribbon wound thereon, is continually pressed against the inside wall surface of a case and wherein the inside wall surface has part thereof of a rough surface and of varying frictional resistance.
