A driving force transmission mechanism includes a first transmission member and a second transmission member that are arranged on an identical rotational center axis. The first transmission member includes one or more transmission claws engaged with the second transmission member. The transmission claw includes, at a position away from the rotational center axis, a fixing portion with respect to the first transmission member, and extends in a direction crossing a direction directed from the fixing portion to the rotational center axis. The second transmission member includes one or more stoppers engaged with a tip end of the transmission claw and one or more holding portions engaged with a side of the transmission claw, which faces the rotational center axis.

A printing apparatus can be downsized while degradation in the print quality can be suppressed. To perform skew correction on a second print medium on which printing is to be performed subsequent to a first print medium, a first conveying unit disposed upstream of the printing position where the printing unit performs printing on the print medium is stopped. Then, driving and stopping of third conveying unit disposed downstream of a second conveying unit is controlled, depending on whether the first print medium after printing has already passed by the second conveying unit when the first conveying unit is stopped, the second conveying unit being driven by the same driving source as that for the first conveying unit and being disposed downstream of the printing position.

A printer includes a head unit and a platen unit. The head unit includes a print head. The platen unit includes a platen roller, a support, and a guide roller. The platen roller is rotatably supported on the support and configured to rotate to convey recording sheet. The guide roller includes a roller part, and the roller part is configured to rotate in contact with the recording sheet as the recording sheet is conveyed.

There is provided a control method for a piezoelectric driving device including a vibrating body configured to vibrate when a driving signal including a periodic signal is applied to a piezoelectric element for driving, a section to be driven that is driven by the vibration of the vibrating body, and a driving-signal generating section configured to generate the driving signal using a pulse signal generated based on a target pulse duty ratio. The driving-signal generating section detects voltage amplitude generated in the piezoelectric element for driving and generates the target pulse duty ratio based on the voltage amplitude. The driving signal includes an intermittent signal formed by an output period in which the periodic signal is output and a suspension period in which the output of the periodic signal is suspended. The driving-signal generating section detects the output-period voltage amplitude and does not detect the suspension-period voltage amplitude.

A rendering apparatus and a carriage for a rendering apparatus are provided, the carriage comprising a repository for a rendering fluid and an integrated mechanical pressure supply to pressurise the repository.

A controller of an inkjet printing apparatus is configured such that, in response to receipt of a preceding command, which notifies transmission of a recording command in advance, from an information processing device through the communication device, the controller executes a separating process to move from a covering position to a spaced position, a moving process to move a carriage, from which the cap is separated, from a first position to a second position, a flushing process to cause the inkjet head to eject the ink toward an ink receiver in response to receipt of a recording command instructing recording of an image on the sheet and upon completion of the moving process, and a recording process to cause a conveyer to convey the sheet and cause the inkjet head to eject the ink in accordance with the recording command, in response to completion of the flushing process.

Provided is a photo printer including: a paper supply unit for accommodating stacked sheets of paper and having a pickup roller protruding from a bottom surface thereof; a platen roller provided at a front end of the paper supply unit; a head provided above the platen roller so as to form an image on the paper fed; a motor for providing a driving force to the platen roller; deceleration gears for decreasing revolutions per minute of the motor; a gear plate provided at one side of the paper supply unit and having the deceleration gears shaft-coupled thereto; and a motor plate having an aligning hole adapted to pass the shaft of the deceleration gear therethrough and a motor hole adapted to pass a rotary shaft of the motor therethrough.
