    摘要： An image formation apparatus has a branching claw with a first guide surface along a side of a sheet to be fed into a reversing path and a second guide surface along a side of a sheet to be fed out of the reversing path. This branching claw is disposed so as to enable switching between a first switching position where the sheet is allowed to be fed into the reversing path through its conveyance along the first guide surface, and a second switching position where the sheet is allowed to be forwarded from the reversing path toward the downstream side of a sheet conveying path through its conveyance along the second guide surface.

    摘要： An image forming apparatus of the present invention includes a printer engine for forming an image on a paper sheet fed from a paper cassette. A paper feeder feeds the paper sheet from the paper cassette to the printer engine while separating it from the other paper sheets stacked on the cassette. A switchback path branches off the transport path of the paper feeder for temporarily storing the paper sheet fed from the paper cassette. The paper sheet fed from the paper cassette enters the switchback path with its leading edge at the head. A roller pair is positioned on the switchback path for switching back the paper sheet received in the switchback path such that the paper sheet leaves the switchback path toward the printer engine with its trailing edge at the head.

    摘要： An abnormality determining apparatus is capable of avoiding mistaken determinations due to the normal value of information obtained by an information obtaining unit differing according to the content of specific information such as the operating mode setting, and deterioration of the determination precision due to a change in the user of a detection subject. The abnormality determining apparatus comprises an information storage unit for storing normal index information serving as an index of a normal state of the detection subject, an information obtaining unit for obtaining a plurality of types of information, and an abnormality determining unit for determining the presence of an abnormality in the detection subject on the basis of the normal index information stored in the information storage unit, and the information obtained by the information obtaining unit. The information storage unit stores a plurality of normal index information having different values. The abnormality determining unit selects, at a predetermined timing, normal index information to be used to determine the presence of an abnormality in the detection subject from the plurality of normal index information.

    摘要： An image forming apparatus is capable of specifying the type of an occurring abnormality to a certain extent while avoiding the increasingly complicated control that is caused when a plurality of abnormalities is detected individually according to the presence of their respective causes. A normal group data set, which is a collection of normal value combinations relating to grouped information constituted by a plurality of information of differing types, is stored in RAM or ROM serving as information storage means of a control unit. At least two or more sets of grouped information, comprising first grouped information constituted by a plurality of different types of information, and second grouped information constituted by a plurality of information in a different combination to that of the first grouped information, are obtained from the RAM, the ROM, various sensors, and an operation display unit. A CPU serving as determining means determines a Mahalanobis distance for each set of grouped information on the basis of the normal group data set and the obtained results of each set of grouped information, and uses this Mahalanobis distance to determine the presence of an abnormality according to categories.

    摘要： An image forming apparatus of the present invention includes a conveyance path extending from a sheet tray to an image forming section. A switchback path with a reversing device is connected to the intermediate portion of the conveyance path for switching back a sheet thereon. The switchback path reduces an interval between consecutive sheets being conveyed in the apparatus for thereby enhancing the productivity of image formation. In addition, the switchback path switches back a sheet being conveyed via a refeed path and the above conveyance path in a duplex print mode, thereby obviating the need of an exclusive switchback path for the duplex print mode. The apparatus is reduced in thickness despite the presence of the switchback path.
