<p>A drive force transmission mechanism is applied to, for example, a printer, to transmit a drive force to a driven element such as a platen, a paper feeder, and an ink ribbon cassette, etc., included in the printer. The drive force transmission mechanism comprises a subsidiary frame (48) detachably attached to a main frame such as a printer frame (12) and having at least one shaft member (70) projected therefrom, and at least one transmission member such as a gear (68) rotatably supported by the shaft member (70) to be engaged with tne driven element so that the drive force is transmitted thereto. Since the transmission member is rotatably supported by the shaft member of the subsidiary frame detachably attached to the main frame, only the subsidiary frame need be replaced if a shaft member is broken.</p> |
