Abstract
A pen force gage for a pen plotter for determining whether the force of a pen positioned by a pen support onto the surface of a drawing media in the pen plotter falls within an acceptable range. The pen force gage includes structure for aligning or positioning the gage within the pen plotter so as to enable the gage to measure the force of the pen; a pivotable arm configured at one end to interact with the pen support as the pen moves toward the surface of the media and at the other end to support a movable weight to determine the force to be applied by the pen on the surface of the media; and an indicator and a reference mark for determining whether the force falls within the acceptable range.
Claims12
A pen force gage for a pen plotter for determining whether the force of a pen positioned by a pen support on the surface of a drawing media in said pen plotter falls within a range of upper and lower pen force limits comprising:
- alignment means for positioning said gage within said pen plotter so as to enable said gage to measure said force of said pen;
- engagement means for interacting with said pen support as said pen moves toward said surface of said media;
- and
- measurement means coupled to said engagement means for determining said force to be applied by said pen on said surface of said media, said measurement means including indicator means for indicating whether said force falls within said range of upper and lower pen force limits.
