摘要： A motor control device is used for controlling a DC motor (30) for secondary paper feeding in, for example, a copying machine. Secondary paper feeding of paper to a transfer drum (18) is achieved by the dedicated DC motor (30). The DC motor (30) is rotated at a high speed at the time of starting the secondary paper feeding and is decelerated up to a process speed after a constant time. At the time of the deceleration, the control device applies a short-circuiting brake to the motor (30). In the short-circuiting brake, there is no variation in braking, thereby to make it possible to reliably decrease the speed of the motor (30). The braking is released at the timing at which an FG clock corresponding to the rotation of the motor (30) is synchronized with a command clock representing the process speed. Consequently, a braking operation is reliably released the instant the speed of the motor (30) reaches a desired process speed.

摘要： The paper-supplying device mainly comprises a pair of paper-supplying rollers (4,5) arranged in opposite up/down relation for putting a bundle of manuscripts (P) placed on a paper-supplying tray (3) therebetween and having an increased frictional circumferential surface portion (4a, 5a) by making the frictional force of one semicircular surface larger than that of the other semicircular surface, a pair of feed rollers (8,9) arranged on the downstream side of the paper-supplying rollers (4,5) with a distance shorter than a semicircular length of the paper-supplying rollers (4,5). Rotation-change over means (16,20) are provided so as to drive the axis of one of said pair of paper-supplying rollers (4,5) for changing over the rotational direction of the pair of paper-supplying rollers (4,5) from a regular to a reverse rotational direction. A pair of assistant rollers (6,7) is arranged above and below of a moving path of said bundle of manuscripts (P) placed on said paper-supplying tray (3) to be rotated in the same direction synchronously with the paper-supplying rollers (4,5) during transmission of an image or a copying process and capable of drawing out the manuscripts in the bundle of manuscripts to the side of said feed rollers (8,9) by means of said increased frictional circumferential surface portion (4a, 5a) of the other paper-supplying roller. Thus, the paper-supplying order of the manuscripts in the bundle can be changed over to a paper supply from the uppermost manuscript and paper supply from the lowermost manuscript in the bundle depending upon the case where the multifunctional machine is to be used, i.e. in a facsimile apparatus function or in a copying apparatus function. Accordingly, the images can be transmitted from the manuscripts beginning with the smallest page number during facsimile transmittance and the copied papers on the other hand can be piled in turn from the smallest page number on top image.

摘要： An automatic document conveying device (4) is applied to an image processor (2) that has a transparent plate. The automatic document conveying device (4) can convey a continuous document (84) that has folding lines (86) extending in the direction of width at stated intervals in the conveying direction and feed holes formed in both side edges thereof at stated intervals in the conveying direction. The automatic document conveying device (4) comprises a continuous document placing means (130) on which will be placed the continuous document (84) in a condition where it is folded along the folding lines (86), a conveying means for conveying the continuous document (84) passing on the transparent plate of the image processor, and a continuous document receiving means for receiving the continuous document conveyed passing on the transparent plate. The conveying means conveys the continuous document (84) from the continuous document placing means (130) passing the transparent plate while unfolding it along the folding lines and further conveys it onto the continuous document receiving means while again folding it along the folding lines. The conveying means includes a conveyer belt mechanism, pin tractor mechanisms, and a conveyance control means that controls the operations of these conveyer belt mechanism and pin tractor mechanisms.
