Abstract: An ink cartridge has pivotable levers connected to walls of a container, and both pawls and protruded guide portions formed on the levers. The pawls are engageable with an ink cartridge holder. The protruded guide portions contact the ink cartridge holder to move the levers in the opening direction. Further, protruded stopper portions are formed to permit pivoting movement of the levers to such a degree as to disengage the pawls from the ink cartridge holder.

Abstract: A car includes a car body having a bottom portion, a wheel that is rotatable, and a supporting member for supporting the wheel, the supporting member being provided to the bottom portion. At least eight pairs of the wheel and the supporting member are provided. The supporting member has a first supporting portion for supporting the wheel rotatably, a second supporting portion for supporting the first supporting portion so that a direction of the wheel supported by the first supporting portion can be changed, and a turning portion that is rotatable about a rotation axis with its axial direction along a direction orthogonal to the bottom portion, the turning portion being provided to the bottom portion. The turning portion supports the second supporting portion so that a distance between the wheel and the bottom portion can be changed, and a position of the wheel can be moved by a rotation of the turning portion in a state that the distance is maintained.

Abstract: A recording apparatus has a paper feeder wherein single sheets of paper can be set, a paper delivery device for transporting paper fed from the paper feeder to a recorder, and a control unit for controlling operation of the paper feeder and the paper delivery device. The control unit has a skew removal execution mode of only the first sheet of paper where the paper tip is bitten into a paper delivery roller forming a part of the paper delivery device and then the paper delivery roller is reversely rotated for ejecting the paper tip for the first sheet of paper at the start of recording and then forward rotating the paper delivery roller for delivering the sheet of paper whose skew is removed to the recorder and delivering the second and later sheets of paper to a record area without executing the skew removal.

Abstract: A first non-recording region is situated in one of both outer sides of a recording region in a main scanning direction of recording. A second non-recording region is situated in the other one of the both sides of the recording region. A power source provides a driving force. A driving gear is interconnected with the power source. A transmission gear is operable to be coupled with the driving gear to transmit the driving force to a rotatable member. An actuator is operable to move in the main scanning direction. A first trigger is disposed in the first non-recording region. A second trigger is disposed in the second non-recording region. A clutch is interconnected with the trigger so as to couple the driving gear and the transmission gear when the one of the first trigger and the second trigger is actuated by the actuator.
