Abstract:
A portable medical data strip chart recorder in which a drive roller for drawing the strip across a platen includes integral motive means for rotating the roller at a selected angular velocity. A D. C. motor is mounted internally and concentrically with the roller shaft which upon energization drives the roller and hence the strip paper at a desired linear velocity. The incorporation of a D. C. motor internally of the drive shaft permits reduction in size and weight of the recorder as well as achieving a more efficient drive power transmission.
