Abstract

A conveying apparatus includes: receiving trays arranged vertically and has a lowest tray and a first receiving tray; a conveying mechanism; a supporter supporting the receiving trays; and a swing mechanism configured to swing the first receiving tray with respect to the supporter to one of a receiving position at which the first receiving tray receives a medium and an upper position. The swing mechanism is configured to: keep the first receiving tray at the upper position when a first external force directed in a direction in which the first receiving tray is moved from the upper position toward the receiving position is not applied to the first receiving tray located at the upper position; and swing the first receiving tray with respect to the supporter toward the receiving position when the first external force is applied to the first receiving tray.

First claim

What is claimed is:

1. A conveying apparatus, comprising:
a plurality of receiving trays each having a receiving surface that receives a medium, the plurality of receiving trays being arranged in a vertical direction, the plurality of receiving trays comprising (i) a lowest tray located at a lowest position among the plurality of receiving trays and (ii) a first receiving tray that is each of at least one of the plurality of receiving trays and the at least one of the plurality of receiving trays does not include the lowest tray;
a conveying mechanism configured to convey the medium to the receiving surface of one of the plurality of receiving trays, selectively;
a supporter supporting the plurality of receiving trays;
a swing mechanism configured to swing the first receiving tray with respect to the supporter so as to move the first receiving tray selectively to one of a receiving position at which the first receiving tray receives the medium conveyed by the conveying mechanism and an upper position at which a position of a downstream end of the first receiving tray in a conveying direction in which the medium is conveyed by the conveying mechanism is higher than a position of the downstream end of the first receiving tray located at the receiving position,
a position-keeper configured to keep the first receiving tray at the upper position when a first external force that is an external force directed in a direction in which the first receiving tray is moved from the upper position toward the receiving position is not applied to the first receiving tray located at the upper position,
wherein the swing mechanism is configured to swing the first receiving tray with respect to the supporter toward the receiving position when the first external force is applied to the first receiving tray, and
wherein the conveying apparatus further comprises a force-reducer configured to reduce a keeping force, of the position-keeper, so as to cease keeping the first receiving tray at the upper position,
wherein the conveying apparatus further comprises:
a recorder configured to perform recording on the medium conveyed by the conveying mechanism; and
a controller configured to, when a recording command for instructing the recorder to perform recording is received, control the position-keeper to move a destination receiving tray of the plurality of receiving trays from the upper position to the receiving position, the destination receiving tray being located at the upper position and serving as a destination to which the medium is to be conveyed by the conveying mechanism.

2. The conveying apparatus according to claim 1 , wherein the controller is configured to control the position-keeper based on the recording command such that each of all receiving trays each located at the upper position among the plurality of receiving trays is moved from the upper position to the receiving position.

3. The conveying apparatus according to claim 1 ,
wherein the plurality of receiving trays comprise a plurality of second receiving trays which are all of a plurality of receiving trays of the plurality of receiving trays other than the lowest tray, the plurality of second receiving trays including the first receiving tray,
wherein the swing mechanism is configured to swing all the plurality of second receiving trays with respect to the supporter so as to move each of all the plurality of second receiving trays selectively to one of the receiving position and the upper position;
wherein the position-keeper is configured to keep each of the plurality of second receiving trays at the upper position when a second external force that is an external force directed in a direction in which said each of the plurality of second receiving trays is moved from the upper position toward the receiving position is not applied to said each of the plurality of second receiving trays which is located at the upper position;
wherein the swing mechanism is configured to swing said each of the plurality of second receiving trays with respect to the supporter toward the receiving position when the second external force is applied to said each of the plurality of second receiving trays, and
wherein the force-reducer is configured to cease keeping the plurality of second receiving trays at the upper position.

4. The conveying apparatus according to claim 1 ,
wherein the plurality of receiving trays comprise a third receiving tray that is each of at least one of the plurality of receiving trays which includes the lowest tray,
wherein the swing mechanism is configured to swing all the plurality of receiving trays with respect to the supporter so as to move each of all the plurality of receiving trays selectively to one of the receiving position and the upper position;
wherein the position-keeper is configured to keep the third receiving tray at the upper position when a third external force that is an external force directed in a direction in which the third receiving tray is moved from the upper position toward the receiving position is not applied to the third receiving tray located at the upper position;
wherein the swing mechanism is configured to swing the third receiving tray with respect to the supporter toward the receiving position when the third external force is applied to the third receiving tray, and
wherein the force-reducer is configured to cease keeping the third receiving tray at the upper position.

5. The conveying apparatus according to claim 1 ,
wherein the swing mechanism is configured to swing each of the plurality of receiving trays with respect to the supporter so as to move said each of the plurality of receiving trays selectively to one of the receiving position, the upper position, and an intermediate position at which a position of a downstream end of said each of the plurality of receiving trays in the conveying direction is higher than a position of the downstream end of said each of the plurality of receiving trays which is located at the receiving position and lower than a position of the downstream end of said each of the plurality of receiving trays which is located at the upper position, and
wherein the plurality of receiving trays comprise (i) an uppermost tray located at a highest position among the plurality of receiving trays and (ii) a lower tray that is one of the plurality of receiving trays other than the uppermost tray;
wherein at least a portion of one of the plurality of receiving trays which is disposed above the lower tray and located at the receiving position and at least a portion of the one of the plurality of receiving trays which is disposed above the lower tray and located at the intermediate position are located on a path through which the lower tray is moved from the receiving position to the upper position via the intermediate position, and the one of the plurality of receiving trays which is disposed above the lower tray and located at the upper position is not located on the path.

6. The conveying apparatus according to claim 5 ,
wherein the plurality of receiving trays comprise a fourth receiving tray that is swung by the swing mechanism with respect to the supporter,
wherein the fourth receiving tray is not kept at the intermediate position by the position-keeper and is kept at the intermediate position by contact with one of the plurality of receiving trays which is disposed under the fourth receiving tray and located at the upper position.

7. The conveying apparatus according to claim 1 ,
wherein the plurality of receiving trays comprise (i) an uppermost tray located at a highest position among the plurality of receiving trays and (ii) a lower tray that is each of at least one of the plurality of receiving trays other than the uppermost tray;
wherein at l
