Abstract: A document conveying device (9) includes a sheet feeding tray (44), a discharge tray (43) provided below the sheet feeding tray (44), a feeding roller (51), a conveying mechanism (35), a lifting mechanism (38) which lifts and lowers the sheet feeding tray (44), a discharge tray document sensor (18) which detects the document on the discharge tray (43), and a control part (10) which controls the lifting mechanism (38) such that the document placed on the sheet feeding tray (44) is pressed against the feeding roller (51) when the conveying mechanism (35) conveys the document. The control part (10) controls the lifting mechanism (38) to lower the sheet feeding tray (44) by a larger amount in a case where the document is not detected by the discharge tray document sensor (18) when power is turned on than a case where the document is detected by the discharge tray document sensor (18).

Abstract: A controller starts sheet feeding at a primary sheet feeding speed, then momentarily stops a sheet feeding rotary member, and thereafter starts secondary sheet feeding. When the secondary sheet feeding speed equals a first speed, the controller momentarily stops the sheet feeding rotary member such that the leading end of a document sheet stops at a first stop position. When the secondary sheet feeding speed equals a second speed, the controller momentarily stops the sheet feeding rotary member such that the leading end of a document sheet stops at a second stop position. The second stop position is located downstream of the first stop position in the document conveying direction.

Abstract: A document feeder includes a lift plate, a pickup roller, a lift motor, a retard roller, and a control unit. In a manual feed mode, the control unit rotates the retard roller to feed a document in a document conveyance direction. Further, the control unit causes the lift motor to start lowering the lift plate while the pickup roller is feeding a document after the rotation of the pickup roller is started.

Abstract: An information processing device includes an acquiring section, an encoding section, and a learning section. The acquiring section acquires log information indicating an operational condition of an electronic device. The encoding section assigns codes uniquely corresponding to the log information to the log information. The learning section applies the codes to a learning model that uses a recurrent neural network to presume an appearance probability of the log information corresponding to the codes.

Abstract: Conveyance modes include a registration mode accompanied with skew correction and a registrationless mode unaccompanied with skew correction. When a jam occurs, the controller interrupts a job, and invokes blank-feed processing starting from a state with all sheets re-set. On invoking blank-feed processing, the controller checks the conveyance mode and recognizes the number of jams. If the conveyance mode is the registration mode and in addition the number of jams has not reached a threshold number of jams, the controller invokes blank-feed processing in the registrationless mode.

Abstract: The document feeder includes a lift plate, a pickup roller, a lift motor, a retard roller, and a control unit. In a manual feed mode, the control unit rotates the retard roller to feed a document in a document conveyance direction. Further, the control unit causes the lift motor to start lowering the lift plate while the pickup roller is feeding a document after starting to rotate the pickup roller. When there is a document set on the lift plate at the time when the pickup roller stops, the control unit automatically resumes the feeding in the manual feed mode.

Abstract: An image forming apparatus according to the present disclosure includes a type identification value measurement portion, a determination portion and a speed adjustment portion. The type identification value measurement portion uses, when the print job is executed, a media sensor previously provided in a paper feed cassette to measure a type identification value for a sheet to be transported in the print job. The determination portion determines whether or not an incidence of paper delay corresponding to the measured type identification value for the sheet exceeds a previously set threshold value. The speed adjustment portion lowers, when as a result of the determination, the incidence of paper delay exceeds the threshold value, a transport speed of the sheet as compared with a normal transport speed to execute the print job.

Abstract: A storage control device includes a first storage unit, a write control unit, and a read control unit. The first storage unit includes a plurality of storage areas corresponding to a plurality of addresses. The write control unit performs a write process to sequentially designate one of the plurality of addresses and write data to the storage area corresponding to the designated address, in a predetermined first order. The read control unit performs a read process to sequentially designate one of the plurality of addresses and read data stored in the storage area corresponding to the designated address, in a second order opposite to the first order, starting with the address corresponding to the storage area in which data has been stored immediately near a predetermined start timing after the beginning of execution of the write process, the read process being started at the predetermined start timing.
