ABSTRACT OF THE DISCLOSURE A motor-operated memorandum device comprising a casing with a window, containing a pair of reels on which each end of a lengthy strip of paper is wound, a reversible electric motor, a power transmission changeover mechanism, a pair of reduction gear trains disposed symmetrically one on each side of the electric motor and connected to the reels, and a compact switch mechanism operated by two push buttons for selecting the direction of rotation of the reels by changing the polarity of the circuit to the electric motor. The power transmission changeover mechanism comprises a pinion fixed to the end of the electric motor shaft, and at least one floating gear, the position of which can be changed by the direction of rotation of the electric motor. When the electric motor rotates in one direction, the pinion brings a floating gear into meshing contact with the first reduction gear in one of the gear trains, and when the motor rotates in the opposite direction the pinion moves a floating gear into meshing contact with the second gear train. Thus, the driving force of the electric motor is transmitted through a floating gear to either of the reduction gear trains and further to one or the other of the reels. It is also possible to rotate the reels manually by means of a knob fixed to one end of each reel. The aforesaid casing may be provided at one end thereof with a manually operated indicator of the month, the day of the month, the day of the week, etc.
