Abstract
A modular-design recorder consists of a "print engine," a drive assembly for moving a print medium, e.g., paper, through the print engine, and a chassis for supporting the engine and the assembly.

The drive assembly consists of a motor, a gear train through which the motor rotates the roller, and a bracket for mounting the motor on the either side of the chassis in a number of different angular orientations. The motor attaches to one end of the bracket, such that it mounts facing either toward or away from the chassis. The opposite end of the bracket mates with the mounting studs on the selected side of the chassis. The print engine consists of a print head, a roller for advancing the paper past the print head and a deflector. The deflector directs the paper in a path that is separate from and circumferential to the roller, such that the roller does not contact the paper until the paper approaches the print head. The recorder also includes a tray for storing the paper, and supplying it to the print engine. The tray includes an end wall that is removably attached to…
