摘要： A digital encoder control method of a digital control apparatus has a driving unit, a frequency signal generating unit for generating a pulse signal of a frequency according to a driving velocity of a driven member which is driven by the driving unit, an edge detecting unit for detecting a rising-up edge and a falling-down edge of the pulse signal, and a period data detecting unit for counting period data between edges detected by the edge detecting unit. Each time the edges are detected by the edge detecting unit, the period data between the same edges as the detected edges is outputted as control velocity data of the driving unit.

摘要： An area on the printing sheet which can be printed through a single scanning operation of a printing head is divided into a plurality of smaller areas. The printing sheet is transported a distance corresponding to each divided area to print the image using different nozzles of the printing head for each divided area. When a back end portion of the printing sheet is printed, the distance transported is reduced to set inoperative nozzles that are not used for the printing operation. Then, when the printing sheet slips out from the upstream roller pair and it is then detected that the printing sheet is to be transported a distance longer than predetermined amount of rotation of the roller, the inoperative nozzles are used to shift an operative nozzle range depending on the extra amount of rotation. Thus, the extra transportation of the printing sheet is corrected.

摘要： In the ink jet recording apparatus, while the formation of an image on the present sheet is in progress, the remaining length-to-rear end Le between the point at which the presence of the sheet is detected by the sheet detection sensor to the rear end of the present sheet and the remaining recording time Tr from the present time point to the time point at which the formation of the image on the present sheet is completed are measured. Further, in the apparatus, the sheet for the next page is supplied from the feed sheet unit when it is found that that the formation of the image on the sheet for the next page is necessary, that the remaining length-to-rear end Le is less than the reference remaining length-to-rear end Lr, and that the remaining recording time Tr is less than the reference remaining recording time TrR.
