    • A stepping motor comprises a rotor assembly including a rotor shaft, a collar coaxially fixed to the rotor shaft, and a cylindrical permanent magnet block fixedly fitted on the collar, a yoke assembly including an inner yoke having a plurality of upper pole pieces arranged at regular angular intervals corresponding to an electrical angle of 2.pi. and a plurality of lower pole pieces arranged at regular angular intervals corresponding to an electrical angle of 2.pi., an upper outer yoke having pole pieces formed so as to extend between the upper pole pieces of the inner yoke, and a lower outer yoke having a plurality of pole pieces formed so as to extend between the lower pole pieces of the inner yoke, first and second driving coils received in a space defined by the inner yoke and the upper outer yoke and in a space defined by the inner yoke and the lower outer yoke, respectively, a base plate fixed to the upper end surface of the upper outer yoke, a flange fixed to the lower end surface of the lower outer yoke, and bearing bushes respectively provided in the central portions of the base plate and the flange to support the rotor shaft therein for rotation. The inner yoke is formed by bending the inner periphery of a single annular plate alternately in opposite directions to form the upper pole pieces and the lower pole pieces.

    • A permanent magnet type stepping motor comprising first and second stator assemblies arranged coaxially about a longitudinal axis. Each assembly includes first and second ring-shaped stators made of magnetic material. The first ring-shaped stator has a central portion with an opening therein, an annular yoke surrounding the periphery of the central portion and a plurality of pole pieces distributed about the circumference of the opening and extending toward a plane transverse to the axis. The second ring-shaped stator has a central portion with an opening therein, an annular substantially planar yoke surrounding the periphery of the central portion and a plurality of pole pieces distributed about the circumference of the opening and extending away from the transverse plane so as to interleave with the pole pieces of the first stator. The central portion of the second stator protrudes from the plane of the yoke in a direction away from the transverse plane. A coil is interposed between the first and second ring-shaped stators and surrounds the pole pieces. The first and second stator assemblies are arranged with respect to the transverse plane so that the second ring-shaped stator of the first stator assembly is adjacent the second ring-shaped stator of the second stator assembly at the transverse plane thereby forming a gap between the protruding central portions of the second stators of the first and second stator assemblies. A permanent magnet having N and S poles distributed alternately about the outer circumference thereof is rotatably supported within the openings in the central portions of the first and second stators of the first and second stator assemblies.

    • A printer includes a platen having a longitudinal axis and a printing head mounted in opposition to the platen. The guide shaft is mounted to extend parallel to the axis of the platen. A carriage supports the printing head and includes a carriage frame mounted on the guide shaft for movement axially therealong and for movement rotatably thereabout and a base plate having a first end integral with the carriage frame and a second end directed away therefrom. A guide plate is fixed at a position below the second end of the base plate and extends parallel to the guide shaft. A parallel link mechanism includes a fixing member attached to a lower surface of the second end of the base plate and a slider memebr connected to the fixing member. The slider member has a slot within which fits the guide plate, such that movement of the carriage axially of the guide shaft causes the parallel link mechanism and the second end of the base plate to be guided by the guide plate. An adjusting screw is threaded through a hole in the second end of the base plate and has a tip end in engagement with the slider member. Thus, upon rotation of the adjusting screw the slider member and the second end of the base plate are moved relatively toward or away from each other, thereby moving the carriage and the printing head rotatably about the guide shaft to increase or decrease the platen gap. A flexible member connects the slider member to the fixing member to prevent the slider member from becoming inclined relative to the guide plate.

    • An image forming apparatus has a fixing unit. A heat roller heats a toner image on a print medium to fuse the toner image. A first temperature detector is in contact with a longitudinal end portion of the heat roller, and generates a first temperature data. A second temperature detector opposes the heat roller and is in proximity to a substantially middle portion of the heat roller. The second temperature detector generates a second temperature data. Depending on the first temperature data and the second temperature data, a controller performs temperature control either in a first mode where the heater is energized such that the first temperature data is equal to a first target value, or in a second mode where the heater is energized such that second temperature data is equal to a second target value.
