Patent number: 4853715Abstract: A pen plotter employs a cable-driven carriage which carries the writing pen and includes a pen-lift mechanism. A shifting idler pulley system located at one side of the plotter returns a pair of drive cables from the opposite side of the carriage to a rotatable drive drum located on the opposite side. The idler pulleys are shiftable equally and in opposite directions toward and away from the pen carriage. One cable is connected to the carriage by being tensively trained about a pen-lift mechanism drive wheel on the carriage. Shifting the idler pulleys causes said drive wheel to rotate without affecting the lateral position of the pen carriage and, therefore, the shifter mechanism independently controls the up/down motion of the writing pen. One drive cable, therefore, accomplishes the functions of both pen carriage movement and writing pen up/down motion control.Type: GrantFiled: June 17, 1988Date of Patent: August 1, 1989Assignee: Numonics CorporationInventor: Albert E. Paschkis
