Abstract: A hull behavior control system includes a memory and at least one controller coupled to the memory. The at least one controller is configured or programmed to control a propulsion force of the marine vessel using a propeller of the marine vessel, obtain a water surface shape around the marine vessel, estimate movement of a wave based on the water surface shape, and reduce the propulsion force by controlling the propeller when it is determined that an impact force equal to or greater than a threshold value will act on the hull after the hull travels over the wave whose movement has been estimated.

Abstract: A scanner includes the following features. A first driven roller sandwiches a document together with a first drive roller and is capable of rotating in a driven manner. A second driven roller sandwiches a document together with a second drive roller and is capable of rotating in a driven manner. A driving unit rotationally drives the first drive roller and the second drive roller. A transmission unit transmits a rotational force from one of the first driven roller and the second driven roller to another of the first driven roller and the second driven roller.

Abstract: An image reading apparatus includes a lower unit, an upper unit, a flexible flat cable (FFC), a GND harness, an accommodating portion, and a widened portion. The lower unit includes a main board. The upper unit includes a sub-board and is pivotably connected to the lower unit. The FFC and the GND harness have flexibility and couple the main board and the sub-board to each other. The accommodating portion accommodates the FFC and the GND harness. A length of the GND harness in a width direction is larger than a length corresponding to a gap between the accommodating portion and the FFC.

Abstract: An image reading apparatus includes a feed roller configured to feed paper toward a reading section, and a medium detection section provided along a transport path between the feed roller and the reading section and configured to include a transmitting portion configured to output an output value equivalent to a magnitude of an ultrasonic wave, and determines whether the transport of the paper is to be continued or to be brought to a halt on the basis of a lower limit value and an upper limit value for the output value, which are set in accordance with the kind of the paper. Further, in a case where the output value satisfies a first condition, a transport of the medium is continued, and in a case where the output value satisfies a condition different from the first condition, the transport of the medium is brought to a halt.

Abstract: An image forming apparatus includes an image bearing member which is movable; an electrifying device which makes contact with the image bearing member and electrifies the image bearing member; a developing device for developing a latent image on the image bearing member by toner; and an abutting member which is provided on a downstream side in a moving direction of the image bearing member with respect to the electrifying device and the contacting portion of the image bearing member and abuts against the image bearing member. The image bearing member, electrified by the electrifying device, is exposed to have the latent image formed thereon, a toner image formed on the image bearing member by the developing device is transferred to a recording material, and the developing device recovers residual toner on the image bearing member after transfer.

Abstract: Toner particles fly off from a photosensitive drum to an exposure light emitting portion by a change of electric potential distribution on the photosensitive drum caused by image exposure in a following process. This causes a poor copy of an image by adhering the toner particles to the exposure light emitting portion. This phenomena affects a tandem type of copiers with multi-stations including photosensitive drums and exposure light emitting positions. An apparatus capable of suppressing toner adhesion to an exposure is provided to solve the above problem.
