Abstract
Abstract The present invention discloses a serial printer for reciprocating a carrier along a platen by means of a wire, wherein the wire is connected to a wire retainer, which is a member separated from the carrier, to form a wire route, the carrier being detachably mounted on the wire retainer whereby the carrier may be removed with the wire remained stretched. Maintenance, checking and repair are easily accomplished and initial assembling is accomplished in a very simple manner.

Claim 1
Independent Claim
206 words
A serial printer comprising: (a) a pair of side plates opposed to each other; (b) a platen extending between said pair of side plates; (c) a carrier; (d) a printing head mounted on said carrier; (e) first means for slidably mounting said carrier so that said carrier may be reciprocated along said platen; (f) a wire retainer; (g) second means for connecting said wire retainer to said carrier, said second means permitting ready detachment of said carrier from said wire retainer; (h) a motor which can be rotated normally and reversely; (i) a winding drum driven by said motor; (j) a wire which is trained over said winding drum and which is connected to said wire retainer such that rotation of said motor while said carrier is attached to said wire retainer causes corresponding movement of said carrier and of said printing head; (k) a base member which is fixed relative to said side plates; and (l) third means for temporarily fixing said wire retainer to said base member while said carrier is detached from said wire retainer for repair or the like, said third means not requiring that said wire be disconnected from said wire retainer while said carrier is detached from said wire retainer.
