Abstract: PROBLEM TO BE SOLVED: To solve such a deficiency that gear tips collide with each other when a switching gear is engaged with a counterpart gear so as to generate collision noise, in a power transmission device such as a facsimile terminal equipment having the switching gear and for rotating a switching cam of a power transmitting path by reverse rotation of a motor. SOLUTION: The device is formed in such a constitution that a switching cam 7 is rotated by means of reverse rotation of a motor 1, a power transmitting path-switching gear 10 provided on a power transmitting path-switching arm 9 driven with the switching cam 7 is engaged with a counterpart gear 11. Pressure cone apex (a) is fixed so as to prevent the switching gear 10 from engaging with the counterpart gear 11 in the case where transmission of power is broken, without carrying out displacement of the forcible pressure cone apex (a) of the switching cam 7. In the case where power is connected, a power transmission device for composing a groove of the switching cam 7 is formed so as to make the pressure cone apex (a) in a free condition.  It is thus possible to prevent gear tips of the switching gear 10 and the counterpart 11 from colliding with each other, and it is also possible to enable smooth connection of the power transmitting path to be closed.

Abstract: PROBLEM TO BE SOLVED: To guarantee the positioning of a plotting pattern for plotted bodies of the same standards with high precision by detecting a position shift quantity in advance and correcting vertical-scanning plotting start position data according to the detected quantity. SOLUTION: To guarantee the high-precision positioning of the plotting pattern for the individual plotted bodies of the same standards, a CCD camera 82 for a laser beam position shift detection detects the quantity of shifts of scanning positions of, for example, 16 scanning laser beams. At the start of plotting operation, a plotting table 18 is moved toward a plotting start position along the vertical scanning direction and pattern plotting is started. When the 16 scanning laser beams SLB shift in scanning positions in the vertical scanning direction, the plotting start position in the vertical scanning direction is shifted by the shift quantity. The shift quantity, however, is already found, so the start timing of the pattern plotted with the 16 scanning laser beams SLB is shifted according to the shift quantity.
