    摘要： A paper-feeding device which includes a paper-feeding cassette removably located into an image processing apparatus, a locking mechanism for inhibiting extraction of the paper-feeding cassette by engaging with the cassette or a cassette mount, and a locking control device for activating operation of the locking mechanism while a paper-feeding operation is underway. Since the locking control device remains activated while the paper-feeding operation is underway, the operator cannot extract the paper-feeding cassette from the image processing apparatus during a paper-feeding operation.

    摘要： A sheet feeder includes a feeder for feeding a sheet, a cassette for containing a plurality of stacks of small sized sheets side by side therein, the cassette including a plurality of biasing members for biasing the respective stacks of small sized sheets upwards so as to bring uppermost sheets of the respective stacks into contact with the feeder, a plurality of sheet detectors arranged in positions corresponding to the respective stacks of sheets for detecting the height of the respective stacks of sheets contained in the cassette, and a controller responsive to the plurality of sheet detectors for determining the absence of sheet in the cassette when at least one of the plurality of sheet detectors detects that the height of the stack has become lower than a predetermined height, and stopping a sheet feeding operation. This sheet feeder prevents the transfer device of an image forming apparatus from being smeared due to the fact that the small sized sheet is fed from only one stack.

    摘要： An image forming apparatus includes a mount portion which permits a cassette containing a plurality of stacks of sheets arranged side by side in rows to be mounted to the image forming apparatus; a feeder for feeding sheets side by side in a state where the cassette is mounted to the mount portion; an imaging assembly for forming an image on each of the sheets being fed side by side; a sheet sensor for detecting the presence or absence of a sheet contained in the cassette for each row; and a control unit for, when the absence of a sheet is detected in any of the rows, stopping at least an image forming operation along a corresponding transport path. Accordingly, even if all the sheets run out in any one of the rows, the corresponding transport path and the like can be prevented from getting smeared due to the image forming operation carried out despite the fact that no sheets are being fed.

    摘要： An image forming apparatus having a plurality of copy paper detector sensors in a delivery passage for copy paper. After a first copy paper detector sensor has been turned ON, if a copy paper detector sensor just downstream of the first copy paper detector sensor is not turned ON within a predetermined period of time, there are checked the ON/OFF status of the first copy paper detector sensor and copy paper detector sensors upstream thereof. If one or more of the copy paper detector sensors are ON, the length of the copy paper is compared with a distance between each of the last-mentioned copy paper detector sensors and a copy paper detector sensor just downstream thereof. Based on the comparison result, the position where the copy paper has jammed, is judged.

    摘要： A paper feeding device is capable of judging that a paper jam occurs on the basis of output from a first paper detecting switch and a second paper detecting switch. These paper detecting switches are respectively provided ahead of and behind a registration roller which feeds paper sheets to an image forming section. If the first paper detecting switch is turned on when a predetermined time has elapsed since the registration roller started to feed a paper sheet to the image forming section, it is judged that a duplicate paper feeding state has occurred where a plurality of paper sheets are simultaneously fed. If the second paper detecting switch is turned off in the case where it is judged that a duplicate paper feeding state has occurred, it is judged that a paper jam has not occurred. The registration roller is stopped so it will later be ready to feed the subsequent paper sheet. Even when the paper sheets are simultaneously fed in a duplicate paper feeding state, it is not judged that a paper jam occurs as long as the paper sheets are fed one at a time to the image forming section. However, if both the first and second paper detecting switches remain on after the predetermined time, then it is judged that a paper jam has occurred.

    摘要： A parallel transport apparatus for transporting sheets side by side along a plurality of transport paths is provided with a feed roller which is brought into contact with uppermost sheets of a plurality of stacks of sheet contained side by side in a cassette and is adapted for feeding the uppermost sheets side by side; a separation roller pair arranged at a specified position of each of the plurality of transport paths and adapted for separating the sheets fed side by side so that one each of sheets are transported along the respective transport paths simultaneously; a sheet detector arranged downstream from the separation roller pair with respect to a sheet transport direction and adapted for detecting the presence or absence of sheets being transported side by side; and a multifeed discriminator for discriminating whether the multiple feeding has been occurred along any of the transport paths in accordance with an output from the sheet detector. Accordingly, the multiple feeding of sheets being transported side by side can be detected and coped with automatically.
