    摘要: A switching device is provided for a sewing machine for switching operation of the sewing machine from a zigzag stitching to embroidering or vice versa. The switching device comprises a rotatable disc fixedly mounted on an output shaft of a stepping motor and a sliding member that movably connects one end of a transmission rod via a pin, the other end of which is connected to a needle bar supporter or a fabric feed device, with the rotatable disc so that the one end of the transmission rod is movable between a first position on the rotatable disc which coincides with the center of rotation of the rotatable disc, and a second position on the rotatable disc which is spaced apart from the center of rotation of the rotatable disc. The switching device further comprises a stopper that engages a stub projecting from the transmission rod, in the first position of the one end of the transmission rod on the rotatable disc, and a mechanism for converting rotational movement of the stepping motor output shaft to movement of an embroidering frame in an X- or a Y-directions, dependent on whether the other end of the transmission rod is connected to the needle bar supporter or the fabric feed device, respectively, when the stopper engages the stub.

    摘要: In a wire-dot impact type printer a cylindrical platen and a printing paper are rotated or transported at the same rate, by connecting them to a single and common electric motor through a first and second transmission mechanisms, respectively. The first transmission mechanism directly connects the platen to the motor to cause the former to rotate together with rotation of the latter in any direction, whereas the second transmission mechanism includes a clutch composed of a first and a second members rotatable about a common center axis but separately from each other in which the first member is caused to rotate together with rotation of the motor in any direction while the second member is caused to rotate together with the first member being rotated in one direction but prevented from rotating when the first member is rotated in the other direction. In the latter case the platen is rotated for color changing operation, but the printing paper is prevented from running through the printer.

    摘要: In a wire-dot impact type printer, a single electric motor is employed for rotating a platen provided at a periphery thereof with a plurality of ink saturated members to thereby change a color to be applied to a printing paper, as well as for rotating tractors cooperated with feed rollers to thereby transport the printing paper in a predetermined direction. A transmission mechanism for transmitting rotational movement of the motor to the tractors comprises a switch disc rotated together with the motor and having a circular periphery thereof which is half toothed and half untoothed, and a clutch composed of a first rotating disc rotated due to engagement with the toothed half portion of the switch disc and a second rotating disc capable of rotating together with the first rotating disc being rotated in one direction to thereby cause the tractors to rotate for the paper feeding operation, but prevented from rotation when the first rotating unit is rotated in the opposite direction. The platen is rotatable in both directions by the reversible motor while the switch disc is positioned such that the first rotating disc of the clutch confronts the untoothed half portion of the switch and is not in mesh with the toothed half portion, which makes the tractors inoperative so that the printing paper remains standstill.
