Abstract: A medium transport apparatus includes a body portion, an inversion unit, and an extension unit. The body portion has a second manual feed path for a sheet material. The inversion unit is configured to be mounted on and separated from the body portion, covers the second manual feed path when the attachment/detachment portion is mounted the body portion, and exposes a portion of the second manual feed path when the attachment/detachment portion is separated from the body portion. The extension unit is configured to be attached to and detached from the attachment/detachment portion. The extension unit extends, in a state in which the inversion unit is separated, the second manual feed path in a transport direction of the sheet material by being detached from the inversion unit and attached to the body portion.

Abstract: A recording apparatus includes: a recording section that performs a recording operation on a medium; a housing that contains the recording section; a storage section that stores the medium; and a reading unit disposed in an upper portion of the housing. The reading unit includes: a reading section that reads an original sheet; a guide member that guides the original sheet; and an aperture through which the original sheet that has been read by the reading section passes. By being rotated relative to the housing, the guide member is switched between a first position in which the aperture is exposed and the original sheet is to be guided and a second position in which the aperture is covered.

Abstract: A recording apparatus includes a power transmission unit configured to be in a power transmission state in which power of a motor is transmitted to a medium reception tray and a power non-transmission state in which the power of the motor is not transmitted to the medium reception tray, and a switching lever unit configured to switch between the power non-transmission state and the power transmission state. The switching lever unit rotates between a contact position and a non-contact position. When the switching lever unit is at the contact position, the switching lever unit switches between the power non-transmission state and the power transmission state by sliding in contact with the carriage as a carriage reciprocates.
