An information processing device includes an information processing part performing an information processing with memory information, a first storage device, a storage device connection part connecting with a second storage device, an operation part, and a control part. The control part, in a case where the second storage device is connected to the storage device connection part, stores the memory information stored in the second storage device in the first storage device and removes the memory information from the second storage device, and, in a case where a releasing operation of the connection between the second storage device and the storage device connection part is performed by using the operation part, stores the memory information stored in the first storage device in the second storage device.

An image reading apparatus includes a sheet support surface, a reading unit, a main body portion configured to accommodate the reading unit, and a flat cable being curved while the reading unit moves in the sub-scanning direction, wherein the main body portion includes a sliding contact surface configured to be brought into sliding contact with a flat surface of the flat cable, and a side surface facing the reading unit in the sub-scanning direction, the housing includes a first surface facing the sliding contact surface and abutting against the flat surface of the flat cable, a second surface facing the side surface, and a connecting surface configured to connect the first surface and the second surface, and the connecting surface abuts against the flat surface of the flat cable in a case where the reading unit performs the reading operation.

An image forming apparatus includes an image forming unit configured to perform image formation on a sheet, a casing configured to house the image forming unit, an operation unit configured to receive an operation performed by a user, an electric wire extending from the casing to be connected to the operation unit and configured to transmit an electrical signal, a reinforcing member provided separate from and independent of the electric wire, the reinforcing member interconnecting the casing and the operation unit, and a covering configured to enclose therein the electric wire and the reinforcing member, wherein the reinforcing member is fixed to the casing and the operation unit in such a manner that a distance between a portion fixed to the casing and a portion fixed to the operation unit in the reinforcing member is shorter than a total length of the electric wire.

An image reading apparatus includes a main body, a cover, a reading unit, a cable, and a shield member. The cover pivots with respect to the main body and move between a first closed position and a first open position. The reading unit pivots with respect to the main body and reads an image of a sheet conveyed in the conveyance path. The cable bridges between the main body and the reading unit and configured to transmit an image signal from the reading unit. The cable includes an exposed portion located between the main body and the reading unit and exposed to an outside of the main body and the reading unit when the cover is located in the first open position. The shield member has conductivity, grounded, and disposed to cover the exposed portion of the cable.

A connector includes a housing, a switch, a set portion, and a contact terminal. An insertion port and a guide hole are formed in the housing. A flat cable is inserted in the insertion port. The guide hole is a through hole passing through the housing in a direction perpendicular to an insertion direction of the flat cable. When the switch moves along the guide hole in a removal direction opposed to the insertion direction, the set portion protrudes outside the housing from the insertion port. A connection portion of the flat cable is set on the set portion. When the switch moves along the guide hole in the insertion direction, the set portion is stored in an inner space of the housing. The contact terminal contacts and presses, in the inner space, a conductor provided in the connection portion.

An image reading apparatus includes: an optical unit movably provided to a device main body; a flexible flat cable connected to the optical unit and to the device main body through a curved portion; a first friction surface on which the flexible flat cable abuts on an opposing surface of the device main body opposing the optical unit; and a second friction surface having a frictional force smaller than that of the first friction surface on which the flexible flat cable abuts on the opposing surface, wherein when the optical unit is positioned at an end portion on one side in a moving direction, the flexible flat cable abuts on the first friction surface, and the flexible flat cable further abuts on the second friction surface on a side where the curved portion is formed outside of the first friction surface in the moving direction of the optical unit.

An image forming apparatus temporarily stores, in an image memory, image data generated by a front surface reading unit and a back surface reading unit for reading images of a front surface and a back surface of an original respectively. A CPU of an image forming apparatus, at a time of starting a copy job, sets an output frequency of the image memory (transfer rate of image data) to a first frequency F1 that is lower than a second frequency F2. The CPU sets the output frequency of the image memory to the second frequency F2 when transfer of the image data of the first page which corresponds to the front surface of a first original completes.

A method of using an interface device to interface to a processing unit is disclosed. The interface device and the processing unit are part of a station of a plurality of stations in a sheet processing line. The method involves using the interface device to receive a control signal from an upstream station, and comparing a selection part of the control signal with a reference, the selection part being part of an addressing part of the control signal. If the comparison result is negative, a further control signal is determined from the control signal, which is derived from and differing from the addressing part of the control signal and the interface device outputs the further control signal to a different interface device corresponding to a processing unit of a downstream station. If the comparison result is positive, an instruction signal is sent from the interface device to the processing unit.
