摘要: A medium supporting mechanism includes a medium supporting unit and a medium holding unit. The medium supporting unit includes a support face that supports a medium, a guide rail intersecting a transport direction in which the medium is transported, and an engaged portion positioned upstream of the first guide rail. The medium holding unit includes a holding portion that covers an edge of the medium in a width direction, an abutting portion movable between an abutting position and a separation position, a switching portion that switches a position of the abutting portion between the abutting position and the separation position, and an engaging portion engageable with the second guide rail. The medium holding unit includes a pressing portion downstream of the abutting portion in the transport direction. The pressing portion presses the support face to move a position of the holding portion in a direction away from the support face.

摘要: An ink-jet recording apparatus includes a recording head, an irregularity detecting unit, a recording medium conveyance unit, and a control unit. The irregularity detecting unit detects an irregularity with the recording medium conveyed toward the recording head. The recording medium conveyance unit has a recording medium diversion unit into which the recording medium with which an irregularity has been detected by the irregularity detecting unit is conveyed. The control unit can perform flushing operation and, when the irregularity detecting unit detects an irregularity with the recording medium, the control unit cancels the flushing operation set immediately before the recording medium with which the irregularity has been detected and conveys, by controlling the recording medium conveyance unit, the recording medium to the recording medium diversion unit.

摘要: A supply device for a roll medium includes a drawer-type lower holding unit configured to support a shaft of a roll medium to hold the roll medium, and a guide member configured to be pressed in a direction toward the shaft from below to come into contact with the roll medium held by the lower holding unit, and be displaced in accordance with a change in an outer diameter of the roll medium. In addition, the lower holding unit is configured to be drawn from a main body of the supply device in a first direction. When the lower holding unit, in a drawn-out state, is stored in the main body of the supply unit, the guide member comes into contact with the roll medium. The guide member is caused to be retracted downward from a travel path of the lower holding unit against a force pressing upward from below.

摘要: An ink-jet recording apparatus includes: a roller; a first supporting member; a recording section; a second supporting member; and a first waved-shape imparting mechanism configured to impart, to the sheet, the waved shape so that both end portions of the sheet in the width direction are oriented downward. An upstream end portion, of the second supporting surface, in the conveyance direction is located below a downstream end portion of a first supporting surface of the first supporting member in the conveyance direction. The second supporting surface of the second supporting member is formed with projections arranged respectively at locations, of the second supporting surface, at which the both end portions of the sheet in the width direction are supported, the projections projecting upward above a location of the second supporting surface at which a central portion of the sheet in the width direction is supported.
