Filed: 1987-11-30
Abstract: PURPOSE:To contrive a simpler construction and high operability by turning a ribbon guide frame on a fulcrum to switch a printing zone of a ribbon, and using a reversing action of the rotating direction of a ribbon spool as a drive source. CONSTITUTION:A pair of left and right spool-driving shafts 3, 4 are rotatably supported on a horizontal surface 2 of a main frame 1. On both sides 9, a ribbon guide frame 10 is supported so that it can be turned with middle parts of both sides as fulcrums. Both ends of a shaft body 13 fitted loosely in a hole 12 provided at a central rear end part of the frame 10 are supported, with a bracket 14 as a stationary part. A screw pipe 17 is engaged with a middle part of the shaft body 13. Springs 19, 20 provided at both ends of the shaft body 13 elastically clamp the pipe 17 and the rear end of the frame 10 therebetween. Each time the feeding direction of a ribbon is reversed, the screw pipe 17 is given a rotating force, and the ribbon guide frame 10 is turned under the functions of the springs and gears 19, 20. Therefore, a printing zone is shifted up and down.

IPC: F24F1/02
Filed: 1994-12-08
Abstract: PURPOSE: To enable a centrifugal fan to be connected to a motor shaft from the front side and to improve the mounting operability of the fan by dividing a lower fan casing to an air drum and a front surface at the position opposed to the fan. CONSTITUTION: A substantially L-shaped part and a substantially inverted L- shaped part are formed integrally with an air drum or a front surface 4a. Thus, the surface 4a is so held by the L-shaped part and the inverted L-shaped part as to be vertically slidable, and when a centrifugal fan 6 is mounted, the surface 4a can be removed by vertically sliding. Thus, the fan 6 can be easily connected to the shaft from the releasing part of the front surface of the fan casing 4 formed by removing the surface 4a. Thus, since the fan 6 can be connected from the front surface side of the casing 4 to the shaft, the fan 6 can be mounted in the state that a motor mounting base is fixed to a bottom plate 2.
