SEVEN-DAY CLOCK

摘要

A seven day clock includes an open-face and a single hand rotatably mountedto, and generally centrally disposed on, the face. A motor driver rotates thehand at a uniformrate of rotation, about an axis of rotation, in a plane parallel to the face.The hand rotates incomplete 360 degree revolutions about the face once every seven complete days.The face isdemarked into seven contiguous equal sectors each bounded by two radiiextending radiallyoutwardly from the axis of rotation and labelled consecutively with theconsecutive days of aweek. The clock is adapted for a user to apply removable writing so that thewriting overlaysthe face, and so that the removable writing is within the sectors.
