Abstract

A card separation apparatus includes a movable tray having a surface onto which a sheet is conveyed after a card has been separated from the sheet, and a card separation unit mounted on the surface for movement with the movable tray, the card separation unit having an opening through which the sheet is conveyed, and a controller configured to send an instruction to the movable tray to be moved at a predetermined timing after a leading edge of the sheet to which the card is attached enters the opening, so as to cause the sheet to be initially separated from the card.

First claim

What is claimed is:

1. An image forming apparatus comprising:
a paper feeding unit configured to supply a sheet on which a card is attached;
a printing unit configured to form an image on the card attached to the supplied sheet;
a conveying roller configured to convey the sheet together with the card on which the image is formed;
a movable tray comprising
a card separation unit mounted on a surface of the movable tray and having an opening through which the sheet is conveyed; and

a controller configured to move the movable tray so as to separate the card from the sheet when a leading edge of the sheet is conveyed to the opening of the card separation unit.

2. The image forming apparatus according to claim 1 , wherein
the movable tray is movable up and down, and
the controller controls the movable tray to move down at a predetermined timing after the leading edge of the sheet enters the opening.

3. The image forming apparatus according to claim 2 , wherein the controller controls the movable tray to move down at the predetermined timing and stay down until the card has separated completely from the sheet and the sheet is conveyed onto the surface of the movable tray.

4. The image forming apparatus according to claim 3 , wherein
the card separation unit includes a card tray on an upper surface of the card separation unit, and
the card tray is positioned to receive the card that is separated from the sheet by the card separation unit and hold the separated card.

5. The image forming apparatus according to claim 4 , wherein the card tray has a concave portion for storing the separated card.

6. The image forming apparatus according to claim 1 , further comprising:
an ejection sensor configured to detect the sheet conveyed by the conveying roller and send a signal to the controller,
wherein the controller determines, based on the signal from the ejection sensor, a timing for moving the movable tray after the leading edge of the sheet enters the opening.

7. The image forming apparatus according to claim 1 , further comprising:
a restraining pawl configured to discharge the sheet through the opening of the card separation unit.

8. The image forming apparatus according to claim 1 , wherein the controller is configured to determine, based on information about the sheet and a conveying speed of the sheet, a timing for moving the movable tray after the leading edge of the sheet enters the opening.

9. The image forming apparatus according to claim 8 , further comprising:
a communication unit configured to receive the information about the sheet from outside of the image forming apparatus.

10. The image forming apparatus according to claim 8 , wherein the information about the sheet includes size information of the sheet.

11. A method carried out by an image forming apparatus, the method comprising:
supplying a sheet on which a card is attached, to a printing unit;
forming, by the printing unit, an image on the card attached to the supplied sheet;
conveying, from the printing unit to a movable tray, the sheet together with the card on which the image is formed, the movable tray comprising a card separation unit mounted on a surface of the movable tray and having an opening through which the sheet is conveyed; and
moving the movable tray so as to separate the card from the sheet when a leading edge of the sheet is conveyed to the opening of the card separation unit.

12. The method according to claim 11 , further comprising:
maintaining the movable tray at a lowered position until the card has separated completely from the sheet and the sheet is conveyed onto the surface of the movable tray.

13. The method according to claim 12 , wherein
the card separation unit includes a card tray at an upper surface of the card separation unit, and
the card tray is positioned to receive the card that is separated from the sheet by the card separation unit and hold the separated card.

14. The method according to claim 13 , wherein the card tray has a concave portion that stores the separated card.

15. The method according to claim 11 , further comprising:
detecting the conveyed sheet using a sensor that is placed at an upstream side of the card separation unit,
wherein a timing for moving the movable tray after the leading edge of the sheet enters the opening is determined based on detection signals from the sensor.

16. The method according to claim 11 , further comprising:
discharging the sheet through the opening of the card separation unit using a restraining pawl.

17. The method according to claim 11 , further comprising:
determining a timing for moving the movable tray after the leading edge of the sheet enters the opening based on information about the sheet and a conveying speed of the sheet.

18. The method according to claim 17 , further comprising:
receiving the information about the sheet from outside of the image forming apparatus.

19. The method according to claim 17 , wherein the information about the sheet includes size information of the sheet.

20. The method according to claim 19 , wherein the information about the sheet includes a position of the card on the sheet.
