Title: Paper feeding device
Inventor: YAMADA SHINICHI
IPC: B65H5/06
Filed: 1986-04-16
Abstract: PURPOSE:To simplify structure and carry out stable paper feeding by forming a paper feed mechanism for a printing device, a paper feeding device, etc. with only a paper feed roller and a paper feeding guide wall. CONSTITUTION:A paper feed mechanism consists of a paper feed roller 1 and a paper feeding guide wall 2, and a gap A exists in between the roller 1 and the guide wall 2. A sheet of paper 3 which is discharged and coming from the B direction is directed to the gap A and, due to the rotation of the roller 1 in the C direction, the paper 3 is directed to the top end of the roller 1. Since the discharging angle of the paper 3 is changed by the paper feeding guide wall 2, the sheet of paper 3 can be discharged by means of the hardness (stiffness) of the paper 3 and the friction against the paper feed roller 1.

Title: Carriage mechanism for heat transfer printer
Inventor: SUZAKI MASABUMI
IPC: B41J19/18
Filed: 1984-05-08
Abstract: PURPOSE:To prevent useless consumption of a transfer film by performing operation of a coil spring clutch in linkage with a head pressing solenoid to halt the ribbon winding action in the skipping and the returning operation while the load for winding the ribbon which is applied to a carriage transversing drive source is reduced to zero to satisfy the skipping function. CONSTITUTION:In the skipping operation, as the suction force of a solenoid 44 is released, a solenoid lever 46 is turned in the angle by a return force of a head return spring 50, a thermosensitive head 6 is separated from a platen while a pinion 49 meshes with a braking gear 57 and the rotation of the braking gear 57 is constrained. At the same time, one end 56a of a coil spring 56 meshed therewith to keep the coil spring 56 from winding on a pulley 54 and a driven transmission piece 55. Thus, the rotating force working on the pulley 54 is cut off. In the return operation, since the pulley 54 rotates in the opposite direction to that in the printing operation, there is no winding of the coil spring 56 and no rotating force is transmitted.
