Abstract
A printer comprises a type wheel, a print hammer and a guide member each disposed in parallel with a platen. The type wheel and print hammer are both disposed on a carriage body which is laterally reciprocated along a guide shaft. A holder member, on which a print ribbon and a correction ribbon are mounted, is disposed on the carriage body in such a manner as to be switchably turned between an erasing position, where the rear end thereof is lifted up by a predetermined height, and a print position where it is not lifted up. Correction ribbon taking-up mechanisms disposed in the holder member and the carriage body feed the correction ribbon stepwise to switch the position of the holder member. Furthermore, a swing limiter mechanism is provided for restraining the holder member from being lifted up beyond the erasing position.

A printer comprising:
- a body;
- a platen rotatably secured to said body;
- a guide shaft secured to said body parallel to said platen;
- a guide member secured to said body, parallel to said platen;
- a carriage axially movably supported by said guide shaft and guided by said guide member, wherein said carriage supports a type wheel, a print hammer adjacent said type wheel, a print mechanism for driving said print hammer, a swing limiter mechanism, and a holder member for holding a print ribbon and a correction ribbon adjacent said print hammer, and wherein said carriage further includes a frame, an abutment member pivotally connected to said frame and engaging said guide member to guide lateral movement of said carriage, and a release mechanism connected to said frame for releasing a portion of said carriage from said guide member by disengaging said abutment member, said swing limiter mechanism being connected to said release mechanism and abutting said holder member when said abutment member is disengaged from said guide member and being spaced from said holder member when said abutment member is engaged with said guide member,
- said holder member being movable between a print position in which the print ribbon faces said print hammer and an erasing position in which the correction ribbon faces said print hammer and being restrained against movement beyond said erasing position by said swing limiter mechanism.
A printer comprising:
- a platen;
- a guide shaft disposed in parallel to said platen;
- a guide member disposed in parallel with said platen;
- a carriage reciprocated along said guide shaft and guided by said guide member, said carriage including a body carrying a type wheel and a print hammer, and a holder means for mounting a print ribbon and a correction ribbon and movable between an erasing position in which the correction ribbon is able to face said platen, and a print position in which the print ribbon is able to face said platen;
- a swing limiter means for restraining said holder means from being elevated beyond said erasing position;
- and
- an abutment member pivotally connected to said carriage body and engaging said guide member to guide lateral movement of said carriage, and a release means connected to said carriage body for releasing a portion of said carriage from said guide member by disengaging said abutment member, said swing limiter means being connected to said release means and abutting said holder means when said abutment member is disengaged from said guide member and spaced from said holder means when said abutment member is engaged with said guide member.
