Abstract
This invention is a self-adjusting motor mount for holding a driving gear mounted on the shaft of a motor in engagement with a driven gear carried by a back plate disposed in a vertical plane and is particularly useful in a pen plotter. There is a mounting plate carrying the motor and the driving gear. A pivotal mounting carried by the back plate attaches the mounting plate to the back plate at a point above the motor for pivotal movement so as to have the motor pivotally hang from the point. There is a bias spring for resiliently urging the mounting plate to carry the driving gear into engagement with the driven gear. Finally, there is a shock absorber carried by the back plate for absorbing pivotal gear disengaging movement of the mounting plate.
