Abstract
PURPOSE: To minimize electric power loss and stop a motor at a precise stop position, by exerting on the DC motor by position detecting means a particular stop action at every paper feeding action when a rotational paper delivering means is rotated manually.
CONSTITUTION: When photodiodes 28, 29 are detecting the light of a light emitting diode 27 through a slit 24 of a driving gear 10 and a slit 25 of a detection mask 26, an inputted addition signal a can control a DC motor 7 such that the level is always at P positions where the zero level is present. As long as a detected signal d1 from a detector is in the state of "light detected", if a platen manual dial is moved, the motor will return to its particular stop position and remain there, when the dial is released. When the detected signal d1 from the detector has become in the state of "dark detected", the DC motor 7 will be rotated to the next step position, and when the driving gear 10 has completed one revolution, again the particular stop action is exerted on the DC motor 7 to stop it.
