Title: Driving method for one side driving running body
Inventor: SAKAI SHIGEYUKI
IPC: H04N1/04
Filed: 1985-04-18
Abstract: PURPOSE:To execute a run at a high speed without any shake at the time of the run by feeding temporarily a running body of a one side drive by a quantity corresponding to an idle quantity at a turning-back point of the run, and thereafter, starting the next run. CONSTITUTION:A running body 17 is fed temporarily by a quantity corresponding to an idle quantity of the running body 17 and a guide rod 18 at a turning- back point, and thereafter, the next run is started. That is to say, movement of the running body 17 in the turning-back point of the run is shown as a figure. In this case, a full line of the running body 17 shows movement which is executed before the idle quantity is solved, and a broken line shows movement which is executed after the idle quantity has been solved. When the running body 17 is run at a constant speed from the turning-back point, and V0=V1=V2=V3, a guide plate 19 side becomes v0=v1=v2=0, and v3=V3. Therefore, the guide plate 19 side of the running body 17 receives a large acceleration suddenly at the time point of v3, and it becomes one of the causes of a shake. Accordingly, in order to eliminate this shaked run, it is necessary to suppress the speed to v3=V3<Vd (Vd: allowable speed).
