Abstract

In a printing apparatus, a first tray is capable of stacking a sheet discharged from a discharge port. A second tray is accommodated in a lower side of the first tray and is capable of stacking the sheet discharged from the discharge port by being drawn out in a sheet discharging direction from the discharge port. A changing unit changes inclination angles of the first tray and the second tray with respect to the sheet discharging direction according to a drawn-out position of the second tray.

First claim

What is claimed is:

1. A printing apparatus comprising:
a printing unit configured to print on a sheet;
a discharge port configured to discharge a sheet printed on by the printing unit, the sheet being discharged in a discharging direction;
a guide member fixed to the printing apparatus;
a moving tray configured to move between a first position at which the moving tray is accommodated in the guide member and a second position at which the moving tray is capable of stacking the sheet discharged from the discharge port, wherein the moving tray is capable of being drawn out to a third position between the first position and the second position;
a rotating tray configured to rotate relative to the guide member by a shaft which engages the rotating tray and the guide member, the rotating tray being positioned at an upper side of the moving tray so as to be capable of stacking the sheet discharged from the discharge port; and
a cam portion configured to change an inclination angle of the moving tray by abutting against the moving tray,
wherein in a case in which the moving tray is moved from the first position to the second position, (i) the inclination angle of the moving tray is changed by abutting on the cam portion so that a downstream side of the moving tray with respect to the discharging direction is higher than an upstream side of the moving tray, and (ii) the rotating tray is rotated around the shaft by abutting against the moving tray so that a downstream side of the rotating tray with respect to the discharging direction is higher than an upstream side of the rotating tray, and
the inclination angle in a case in which the moving tray is at the third position is the same as the inclination angle in a case in which the moving tray is at the first position.

2. The printing apparatus according to claim 1 , further comprising:
an access cover configured to be movable to positions allowing and restricting access for maintenance from an outside to an inside of the printing apparatus through a space formed above the rotating tray,
wherein the access cover allows the sheet to be discharged from the discharge port to the rotating tray in a case in which the access cover moves to the position restricting the access.

3. The printing apparatus according to claim 2 ,
wherein the access cover is rotatable about a lower end thereof to the positions allowing and restricting the access, and
wherein an upper end of the access cover is positioned on the moving tray drawn out from the guide member in a case in which the access cover rotates to the position allowing the access.

4. The printing apparatus according to claim 1 , wherein
in a case in which the moving tray is at the second position, the inclination angle of the moving tray is greater than an inclination angle of the rotating tray.

5. The printing apparatus according to claim 1 ,
wherein the shaft is arranged inside a main body of the printing apparatus at a time of discharging the sheet.

6. A printing apparatus comprising:
a printing unit configured to print on a sheet;
a discharge port configured to discharge a sheet printed on by the printing unit, the sheet being discharged in a discharging direction;
a guide member fixed to the printing apparatus;
a moving tray configured to move between a first position at which the moving tray is accommodated in the guide member and a second position at which the moving tray is capable of stacking the sheet discharged from the discharge port; and
a rotating tray configured to rotate at the guide member by a shaft which engages the rotating tray and the guide member, the rotating tray being positioned at an upper side of the moving tray so as to be capable of stacking the sheet discharged from the discharge port, the shaft being arranged inside a main body of the printing apparatus at a time of discharging the sheet,
wherein in a case in which the moving tray is moved from the first position to the second position, (i) an inclination angle of the moving tray is changed so that a downstream side of the moving tray with respect to the discharging direction is higher than an upstream side of the moving tray, and (ii) the rotating tray is rotated around the shaft so that a downstream side of the rotating tray with respect to the discharging direction is higher than an upstream side of the rotating tray.

7. The printing apparatus according to claim 6 ,
wherein the shaft is engaged with a hole provided on the guide member.

8. The printing apparatus according to claim 6 ,
wherein a space in which the rotating tray can rotate is formed inside the main body of the printing apparatus and above the rotating tray.

9. The printing apparatus according to claim 6 ,
wherein the moving tray is capable of being drawn out to a third position between the first position and the second position, and
wherein the inclination angle in a case in which the moving tray is at the third position is the same as the inclination angle in a case in which the moving tray is at the first position.

10. The printing apparatus according to claim 6 , further comprising:
an access cover configured to be movable to positions allowing and restricting access for maintenance from an outside to an inside of the printing apparatus through a space formed above the rotating tray,
wherein the access cover allows the sheet to be discharged from the discharge port to the rotating tray in a case in which the access cover moves to the position restricting the access.

11. A printing apparatus comprising:
a printing unit configured to print on a sheet;
a discharge port configured to discharge a sheet printed on by the printing unit, the sheet being discharged in a discharging direction;
a guide member fixed to the printing apparatus;
a moving tray configured to move between a first position and a second position, wherein the moving tray is capable of being drawn out to a third position between the first position and the second position; and
a rotating tray configured to rotate relative to the guide member by a shaft which engages the rotating tray and the guide member, the rotating tray being positioned at an upper side of the moving tray so as to be capable of stacking the sheet discharged from the discharge port,
wherein in a case in which the moving tray is moved from the first position to the second position, (i) an inclination angle of the moving tray is changed so that a downstream side of the moving tray with respect to the discharging direction is higher than an upstream side of the moving tray, and (ii) the rotating tray is rotated around the shaft so that a downstream side of the rotating tray with respect to the discharging direction is higher than an upstream side of the rotating tray, and
the inclination angle in a case in which the moving tray is at the third position is the same as the inclination angle in a case in which the moving tray is at the first position.
