| 摘要 |
This invention relates generally to printing apparatus and more particularly to a document or bank check endorser apparatus for printing on documents moving at high speeds in which the operating parts are combined into a self-contained, unitary assembly designed for installation as a unit in larger data processing equipment and also designed when installed for convenient access to the parts thereof for maintenance purposes. The self-contained, unitary document endorser comprises a printing assembly including a print head releasably secured to one end of a rotatable shaft and a cooperating chute gate assembly forming part of the document transport path, and further comprises an electric motor for continuously driving a fly wheel, a clutch for coupling the fly wheel to the shaft for intermittently rotating the latter and the print head, and a brake device for quickly retarding rotation of the print head upon disengagement of the clutch. The endorser is installed as a unit in supporting structure preferably with the shaft in vertical position and the head at the upper end thereof in accessible detachable for printing on documents successively fed thereby. Included in the chute gate assembly is an impression roller or platen capable of fine adjustment for equalizing the printing pressure on the documents fed thereby. Both the cabinet and the endorser unit are cooperatively designed so that the latter may be installed in either of two positions on opposite sides of the document transport path such that with slight modification of the unit for either position it is capable of printing on the front or the reverse sides of documents conveyed along the path.
