Abstract: An image forming apparatus includes a feeding portion, an image forming portion, a discharge portion, a paper transport path, a plurality of detection members, and a control portion. The image forming portion forms images on sheets of paper fed from the feeding portion. The path transports paper from the feeding portion to the discharge portion via the image forming portion. The detection members detect transport state of paper at respective locations on the path including the feeding portion, between the feeding and image forming portions, within the image forming portion, between the image forming and discharge portions, and the discharge portion. Upon detection of paper jam at any of the locations, the control portion displays, on an indicator, information identifying a location where the jam has occurred, and the image forming portion where paper is detected by the detection members, as locations of paper to be eliminated from the path.

Abstract: A sheet feeder has a feed passage and includes feed roller pairs, sensors, and a controller. The feed roller pairs are arranged along the feed passage and feed sheets of paper in a feed direction along the passage by nipping the sheets. Each of the sensors is fitted at or near one of the feed roller pairs and senses a specified point on each of the sheets when the sheet is nipped by at least the associated roller pair. The controller includes a memory for storing reference feed timings as proper feed timings at each of which the specified points on the sheets should pass one of the sensors. The controller finds the real feed timing when each of the sensors senses the specified point on the sheet nipped by at least the associated roller pair.

Abstract: In one embodiment, in a standby mode, an endless heating belt is caused to move apart from a hot roller. Furthermore, in color mode, the endless heating belt is caused to contact the hot roller to make possible thermal conduction between the endless heating belt and the hot roller, and a surface temperature of the endless heating belt is adjusted within a prescribed range of 200° C. to 210° C. being higher than a fixing temperature of 180° C. Further still, in monochrome mode, a length (or a surface area) of a heating contact region between the endless heating belt and the hot roller is set to a maximum to increase a thermal conduction efficiency between the endless heating belt and the hot roller, and a surface temperature of the endless heating belt is adjusted within a prescribed range of 210° C. to 220° C. being sufficiently higher than the fixing temperature of 180° C.

Abstract: A paper processing device includes a processing unit, a paper ejection roller, a sorting mechanism, a paper overlapping mechanism, and a control unit. The processing unit performs predetermined processing upon sheets of paper being conveyed one at a time along a paper conveyance direction. The roller discharges the sheets in the paper conveyance direction, after completion of processing by the processing unit. The sorting mechanism shifts the roller to and fro between an initial position and a sorting position in a direction orthogonal to the paper conveyance direction. The overlapping mechanism superimposes, between the processing unit and the roller in the paper conveyance direction, a predetermined number of sheets of paper upon which processing has been completed. The control unit superimposes a predetermined number of sheets of paper by operating the overlapping mechanism, before shifting the roller from the initial position to the sorting position with the sorting mechanism.

Abstract: A receiving medium comprising N components is assigned to a channel comprising N components respectively and provided along the circumference around which a rotating frame rotates. At a position facing the receiving medium corresponding to the rotation, the transmission medium of M components (M?2N, N represents an integer more than 2) are arranged separately in a line along the circumference of the rotating frame. A signal generation device produces the signal containing data relating to an object obtained by detection of the X-ray detector device. When the transmission medium is rotated according to the carrier signal to face any of the receiving medium, a switching device transmits the signal from the channel to one of the corresponding receiving medium. When the interval between the two adjacent transmission medium passes through the receiving medium, the signal from the same channel may be transmitted to the two adjacent transmission medium.

Abstract: A data processing apparatus receives and stores data, and then performs processing such as the output of the stored data. The data processing apparatus nullifies already-processed data by means of deletion or overwrite. The data processing apparatus displays a reception screen for receiving from a user a priority instruction for either a processing-speed oriented priority where priority is imparted to the processing of data or a security oriented priority where priority is imparted to the nullification of data. When the security oriented priority is instructed, the data processing apparatus performs the nullification of data immediately after the processing of the data. When the processing-speed oriented priority is instructed, the data processing apparatus performs with priority the processing of data. Then, when not-yet-processed data has been completed, or alternatively after a user has left the site, the data processing apparatus performs the nullification of already-processed data.

Abstract: A receiving medium comprising N components is assigned to a channel comprising N components respectively and provided along the circumference around which a rotating frame rotates. At a position facing said receiving medium corresponding to the rotation, the transmission medium of M components (M>2N, N represents an integer more than 2) are arranged separately in a line along the circumference of the rotating frame in a state such as charge-coupling. A signal generation device produces the signal containing data relating to an object obtained by detection of the X-ray detector device, which is for example, a carrier signal modulated with the data.

Abstract: Cloth is successively conveyed by a supply roller and a take up roller over a platen which opposes an ink jet head selectively jetting ink. The platen has an opening formed at a surface opposing to the ink jet head, and an air suction opening behind the opening of the platen is connected to an air suction unit through an air path. At the time of dyeing, fluff on the surface of the cloth opposing to the ink jet head is sucked and laid down on the surface of the cloth by air suction by the air suction unit, and ink is appropriately jetted to the surface of the cloth from the ink jet head. Therefore, ink jet is not hindered by the fluff on the surface of the cloth at the time of dyeing. Therefore, ink drops can reach the desired position on the surface of the cloth, and satisfactory dyeing without any distortion in patterns is performed.
