The openings have different lengths in a parallel movement direction of the sliding member.

Abstract: There is provided a recording apparatus. The recording apparatus includes: a support member which supports a recording medium; a recording head which applies a recording material to one surface of the recording medium supported on the support member; and a fixing unit which fixes the recording material adhered to the one surface of the recording medium transported from the support member, wherein the support member and the fixing unit are arranged to be partly overlapped with each other in an up and down direction.

Abstract: A recording apparatus includes a transport unit that intermittently transports an elongated recording medium from an upstream side to a downstream side as the lengthwise direction of the recording medium moves along a transport path. A recording unit adheres a recording material to the recording medium when the recording medium is stopped in a midstream position of the transport path. A drying unit downstream from the recording unit heats and dries the recording material. A contact member has a contact surface continuous contact with the surface of the recording medium opposite the surface thereof to which the recording material is adhered, from the time when the recording medium enters into the drying unit to the time when the recording medium is discharged from the drying unit. The contact member forms the transport path with the contact surface having at least one bent section in the drying unit.
