Abstract: A recording apparatus includes a control unit that acquires information regarding shapes and sizes of a recording material and a transport material to which the recording material is to be bonded. The control unit is configured to operate in a first recording mode in which a positioning pattern is recorded on the transport material, the positioning pattern being used to position the recording material on the transport material, and also configured to operate in a second recording mode in which the data is recorded on the recording material positioned on the transport material during transport of the transport material.

Abstract: A printer includes a gap adjustment unit that displaces a carriage in a Z-axis direction in which a gap changes. The gap adjustment unit has a sliding member that moves in a width direction integrally with the carriage, and a cam member that is interposed between the carriage and the sliding member and has a stepped portion in which a maintenance surface that maintains a position of the carriage in the Z-axis direction and an adjustment surface that changes the position of the carriage in the Z-axis direction are alternately arranged in the width direction. The gap adjustment unit is configured such that the cam member slides in the width direction with respect to the carriage and the sliding member to change the gap. The gap adjustment unit includes a buffer unit that decreases a displacement speed of the carriage in the Z-axis direction when the gap is reduced.

Abstract: A moving-side roller reliably separates from a stationary-side roller so as to enable appropriate document transport. An image reading apparatus causes a roller support member supporting the moving-side roller to come into contact with the stationary-side roller. A contact state and a separation state can be switched. The image reading apparatus includes an external force providing portion to exert a third external force on the roller support member in a direction for restraining warping that is generated in the roller support member by a first external force that a cam exerts on the roller support member and by a second external force that an urging device exerts on the roller support member.

Abstract: An image reading apparatus includes a medium reading unit that extends in a main scanning direction and reads an image of a medium while moving in a sub-scanning direction which is a direction crossing the main scanning direction; a signal transmission cable that is a flexible cable having a curved section and connected to the medium reading unit and that deforms following a movement of the medium reading unit; a power supply that supplies power to the medium reading unit; and a housing that accommodates the medium reading unit and the power supply. At least a portion of an insertion/extraction space for inserting/extracting a plug of a power cable from outside the housing to the power supply and at least a portion of an area where the signal transmission cable deforms following the movement of the medium reading unit overlap in a height direction of the medium reading unit.

Abstract: There is provided a transportation apparatus in which a first transportation unit, which transports a paper sheet from a mounting portion, starts transportation of a next paper sheet at a time when a specific time has elapsed after the second transportation unit, which is positioned on a downstream side of the first transportation unit, starts to transport a paper sheet so that an inter-sheet distance between a preceding paper sheet and a following paper sheet becomes optimal.

Abstract: An apparatus includes a gap adjuster that adjusts a gap in a vertical direction between a recording head and a supporting surface for supporting a medium. The gap adjuster adjusts the gap by engagement of a carriage, a slide member, and a cam member that is provided therebetween and has a stepped portion with an alternate-arrangement structure in a width direction. The gap adjuster includes a coil spring that urges the carriage with respect to the slide member in the direction that is the opposite of the transportation direction. A slide contact member is provided on an end of the coil spring.
