摘要:
A display apparatus in the form of a container having display units mounted in subcontainers situated on the interior of the container bottom. Each of the display units has a display segment mounted for pivoting, and a motor for pivoting the segment. Each motor has male terminals extending through an orifice in the bottom of the subcontainer, two support elements which form flexible side plates and a reel for receiving a wire, a rotor mounted between the side plates, and an armature for the reel. The rotor includes a circular magnet mounted on end elements nestable in each other through the magnets central hollow space. Each end element nests in one of the side plates. The display apparatus also includes a plate mounted on the exterior of the container bottom. The plate has female receptors which receive the motor male terminals to form electrical connections, and a printed circuit which connects the electrical connections to a bayonnet connector.
摘要:
Automatic indicia changer, such as a clock-calendar for displaying months, days of the month, days of the week, hours and minutes, comprises a plurality of series of plates bearing the various indicia, each series being rotatable about its axis under the influence of a ratchet wheel that is moved stepwise by a dog, each step changing the indicia one increment. The dog is swung by a lever which in turn is swung by a rotary cam. The first series of indicia is driven by a motor; while the first series drives the second and the second drives the third, and so on. Thanks to the ratchet wheel and pawl drive, each series of indicia can be manually adjusted without interrupting the automatic drive. Manual adjustment may be effected either rapidly, by turning the ratchet wheel with an external knob, or stepwise by pressing with the finger on a protrusion on the associated swingable lever.
