Abstract

An intermittent motion imprinter of the type having a reciprocal marker head suspended from a shaft, an opposed anvil, tape supply and take-up reels, a tape advance mechanism and a reciprocal shuttle driving the head and tape advance mechanism, has a common holder for the head shaft and shuttle with intersecting closed periphery slots respectively receiving and guiding the shuttle and the head shaft. The holder is a two-piece split block defining, when assembled, a transverse slot for the shuttle and an upright slot for the head shaft. A cam follower on the head shaft projects into an inclined slot of the shuttle so that, as the shuttle is reciprocated, the shaft is raised and lowered. A second cam follower is also driven by the shuttle to actuate the tape advance mechanism. In one form, the second cam follower is directly attached to the shuttle. In another form, the second cam follower rides in a second shuttle slot. In one form the shuttle rides in a groove provided in one piece of the split block of the holder with the head shaft riding in a groove provided in the opposite block of the holder. In another form, only one holder block is grooved, receiving both the shuttle and the head shaft with the shaft also being grooved to receive the shuttle.
