A printing apparatus includes a feed side roll, a winding roller, a driver, a detector, a printer, a conveyance roller, and an adjuster. The feed side roll includes an ink ribbon wound on a feeding roller. The driver rotates the winding roller in a direction of winding the ink ribbon. The detector detects a change in a tension of the ink ribbon being wound. The printer prints on a print medium via the ink ribbon stretched in a tense state between a collection side roll where the ink ribbon is wound and the feed side roll. The conveyance roller winds the ink ribbon between the collection side roll and the printer. The adjuster adjusts a torque for rotating the winding roller by the driver based on detection results by the detector to keep a tension of the ink ribbon passing through the printer constant.

Printer

A printer includes a supply-side roll, a winding roller, a detector, a printing assembly, a conveying roller, and an adjuster. The supply-side roll is formed by winding an ink ribbon around a delivery roller. The winding roller winds the ink ribbon. The detector detects a change in tension of the ink ribbon. The printing assembly prints on a printing medium via the ink ribbon stretched between the supply-side roll and a collection-side roll formed by winding the ink ribbon. The conveying roller winds the ink ribbon and rotates in a direction in which the ink ribbon is wound by the winding roller. The adjuster adjusts, based on the change in the tension of the ink ribbon, a frictional force applied between the conveying roller and the ink ribbon and keeps constant tension of the ink ribbon passing through the printing assembly.

A belt drive device includes a drive unit, a detection unit, a blade, and a control unit. The drive unit rotates an endless belt. The detection unit detects a position of a connection portion in which both ends of a reinforcing tape, which is provided on an outer surface of an edge of the belt in a width direction orthogonal to a rotation direction of the belt, in a longitudinal direction along the edge of the belt are overlapped and connected. The blade comes into contact with an outer surface of the belt and an outer surface of the reinforcing tape and is provided to extend in the width direction. The control unit controls driving of the drive unit based on a detection result obtained by the detection unit such that when the drive unit rotates the belt by a constant length in a reverse direction from one end of the reinforcing tape overlapped inside toward the other end of the reinforcing tape overlapped outside at the connection portion from a state in which the belt is stopped, the drive unit rotates the belt in a forward direction to a rotation position where the other end of the reinforcing tape does not come into contact with the blade by a reverse rotation and stops the belt before the belt is reversely rotated.

Belt drive device

An image forming apparatus including: a transfer component including a transfer roller configured to transfer an image; a holding mechanism supported by a cover, configured to hold the transfer component; a lever rotatably between a first position and a second position, configured to pressurize the transfer component to press the transfer roller against an image carrier when the lever is at the first position; and an engagement portion supported by the cover, configured to engage with the lever to move the lever to the first position while the cover is closed, to engage with the lever to move the lever to the second position while the cover is opened, and to disengage from the lever to be separated from a space through which the lever is capable of passing when the lever is positioned at a third position between the first position and the second position.

Image forming apparatus

According to an embodiment, an image erasing apparatus includes a reading unit, an erasing unit, an image forming unit, and a controller. The reading unit reads identification information formed on a sheet conveyed. The erasing unit erases a part or all of a first image formed on the sheet after the identification information is read. The controller obtains image data corresponding to the identification information that is read by the reading unit. The controller controls the image forming unit so as to form a second image, which is indicated by the obtained image data, onto the sheet from which the first image has been erased.

Image erasing apparatus and image erasing method

In accordance with an embodiment, an image processing apparatus comprises a sheet feed cassette, an operation lever, a sliding section, a sheet lifting and lowering tray, and a main body rail section. The sheet feed cassette is housed to be capable of being pulled out from an apparatus main body. The operation lever is arranged at the side of the sheet feed cassette and is rotatable around a shaft positioned at the middle in a longitudinal direction. The sliding section is arranged at the rear side of the shaft of the operation lever. The sheet lifting and lowering tray can place a sheet and adjust an inclination thereof in conjunction with the operation lever. The main body rail section is arranged in the apparatus main body and guides running of the sliding section at the time of pulling out the sheet feed cassette.
