Abstract: In a device for compensating a torque that depends on rotation angle and results from the rotational motion of a mass around a rotation axis, the rotational motion is converted into a linear displacement of a movably mounted displacement unit along a displacement axis in a defined manner depending on the rotation angle. The torque acting at any given time is compensated by an elastic compensating element that exerts a force opposite to the linear displacement of the displacement unit. Such a device is particularly suitable for compensation of torques that depend on rotation angle in medical stands.

A mechanical latch and associated mechanism is provided responsive to a cam on the print rotor and responsive to the movement of the cover, and the mechanism has an electrical sensor output to the processor of the postage meter. In the event that the cover is opened at a time when the rotor is away from its home position, for example at a time when the power to the meter has failed, the latch enters a latched state. Upon the restoration of power the meter determines if the rotor is away from its home position, and if it is, the meter inspects the sensor output to determine if the latch has been caused to enter its latched state. This condition is annunciated, for example by rendering the meter incapable of printing postage.
