Abstract: Provided are devices that can comprise a rotatable image wheel. The rotatable image wheel can comprise a plurality of image panels arranged radially around a central axis and radially offset relative to the central axis. The rotatable image wheel can also be rotatable about the central axis. The device can further comprise a face plate disposed coaxially with the rotatable image wheel and arranged to cover a portion of the rotatable image wheel. The face plate can describe an aperture radially offset with respect to the central axis. The device also comprises an actuator mechanically coupled to the rotatable image wheel and configured for causing rotation of the rotatable image wheel about the central axis relative to the face plate.

Abstract: A device for displaying at least one time-related magnitude including a timepiece movement including at least one time base and at least one energy source which extend in a first same plane, and at least one roller pivotably mounted about an axis of rotation A and which extends in a second plane parallel to the first plane, at least one roller including a display strip arranged on an outer periphery and on which at least one indication of the time-related magnitude is inscribed, the timepiece movement driving at least one roller in rotation about axis A via drive device which extend in the same second plane as at least one roller, at least one roller and the timepiece movement being centred on axis A.

Abstract: A printer countwheel mechanism in a time stamp machine keeps a running count of the number of groups of documents stamped by automatically advancing a countwheel to the next highest number when all documents in the group have been stamped. A document group comprises one or more documents. Each document in the group is stamped with the same countwheel number. When stamping single documents, i.e. groups consisting of only one document, the countwheel is advanced every stamping operation so that every document is stamped with a different number. When stamping duplicates, i.e. groups of two documents, the countwheel is advanced every other stamping operation so that duplicates are stamped with the same number. The mechanism may also be disengaged when it is not necessary to keep a count of the number of documents stamped.
