Abstract
A paper sheet conveying apparatus and method for an image information processor in which a paper sheet with image information recorded thereon can be prevented from a skew carriage. The paper sheet conveying apparatus includes a driving motor which is controlled to be shifted from a forward revolution mode to a reverse revolution mode or vice versa. The paper conveying apparatus further includes a power cleaving means that selectively supplies the power to a first power transmitting system and to a second power transmitting system.
Claims4
A method for conveying and aligning a paper sheet in an image information processor, the image information processor having a paper sheet separating roller, a paper sheet aligning roller and a paper sheet ejecting roller, the method comprising:
- feeding a paper sheet toward the aligning roller;
- providing, selectively, a rotational driving force by a driving motor in a forward revolution to the paper sheet separating roller and to the paper sheet ejecting roller, wherein the paper sheet aligning roller is not provided with the rotational driving force and is not rotating;
- conveying the paper sheet into the non-rotating aligning roller and a non-rotating back-up roller, which faces the aligning roller, for a predetermined amount of time, so that the paper sheet is aligned;
- and
- shifting the driving motor to a reverse revolution so as to provide a rotational driving force, after the predetermined time has expired, to the paper sheet separating roller, the paper sheet aligning roller and the paper sheet ejecting roller, so that the paper sheet is conveyed to an image reading portion.
