A liquid ejecting apparatus comprising: a carriage that mounts a liquid ejecting head provided with a nozzle surface in which nozzles to eject a liquid are formed, the carriage being configured to move the liquid ejecting head between an ejection area used to cause the liquid ejecting head to eject the liquid onto a medium and a maintenance area used to perform maintenance of the liquid ejecting head; a liquid supply coupling portion that is mounted on the carriage and is detachably coupled to the liquid ejecting head so as to supply the liquid to the liquid ejecting head; a carriage movement mechanism that is configured to move the carriage when the liquid supply coupling portion is to be detached, to a detachment position provided in the maintenance area; and a liquid receiving portion that has a size equal to or larger than the nozzle surface, is opposed to the nozzle surface located at the detachment position, and receives the liquid discharged from the nozzles; wherein a wiping device is provided in the maintenance area; further comprising: a control portion configured to cause the carriage to move and locate the liquid ejecting head at the detachment position by controlling the carriage movement mechanism when the liquid supply coupling portion is to be detached, characterized in that: the wiping device includes a belt-like member having a width equal to or larger than the nozzle surface, and configured to wipe the nozzle surface by bringing a portion of the belt-like member into contact with the nozzle surface, and the liquid receiving portion is formed by drawing out the belt-like member such that a different portion of the belt-like member is opposed to the nozzle surface located at the detachment position. a carriage that mounts a liquid ejecting head provided with a nozzle surface in which nozzles to eject a liquid are formed, the carriage being configured to move the liquid ejecting head between an ejection area used to cause the liquid ejecting head to eject the liquid onto a medium and a maintenance area used to perform maintenance of the liquid ejecting head; a liquid supply coupling portion that is mounted on the carriage and is detachably coupled to the liquid ejecting head so as to supply the liquid to the liquid ejecting head; a carriage movement mechanism that is configured to move the carriage when the liquid supply coupling portion is to be detached, to a detachment position provided in the maintenance area; and a liquid receiving portion that has a size equal to or larger than the nozzle surface, is opposed to the nozzle surface located at the detachment position, and receives the liquid discharged from the nozzles; wherein a wiping device is provided in the maintenance area; further comprising: a control portion configured to cause the carriage to move and locate the liquid ejecting head at the detachment position by controlling the carriage movement mechanism when the liquid supply coupling portion is to be detached, characterized in that: the wiping device includes a belt-like member having a width equal to or larger than the nozzle surface, and configured to wipe the nozzle surface by bringing a portion of the belt-like member into contact with the nozzle surface, and the liquid receiving portion is formed by drawing out the belt-like member such that a different portion of the belt-like member is opposed to the nozzle surface located at the detachment position. a control portion configured to cause the carriage to move and locate the liquid ejecting head at the detachment position by controlling the carriage movement mechanism when the liquid supply coupling portion is to be detached, characterized in that: the wiping device includes a belt-like member having a width equal to or larger than the nozzle surface, and configured to wipe the nozzle surface by bringing a portion of the belt-like member into contact with the nozzle surface, and the liquid receiving portion is formed by drawing out the belt-like member such that a different portion of the belt-like member is opposed to the nozzle surface located at the detachment position. the wiping device includes a belt-like member having a width equal to or larger than the nozzle surface, and configured to wipe the nozzle surface by bringing a portion of the belt-like member into contact with the nozzle surface, and the liquid receiving portion is formed by drawing out the belt-like member such that a different portion of the belt-like member is opposed to the nozzle surface located at the detachment position.
