## Abstract

A sheet receiving and stacking apparatus includes a base table with a stacking section for stacking a rectangular sheet, and a guide device for receiving the rectangular sheet and guiding the rectangular sheet to the stacking section of the base table. The guide device has a plurality of guide sections rotating in contact with the rectangular sheet above said stacking section.

## Claims

### Claim 1

A sheet receiving and stacking apparatus, comprising:
a base table with a stacking section for stacking a rectangular sheet, and
guide means for receiving said rectangular sheet and guiding said rectangular sheet to said stacking section of said base table, said guide means having a pair of side boards provided on the base table parallel to a direction of discharge of the rectangular sheet for defining the stacking section, and a plurality of guide sections rotatably supported near the side boards, each side board having a window therein and one of said guide sections protruding into the stacking section through the window so that when the rectangular sheet is discharged above said stacking section, the rectangular sheet contacts said one of the guide sections to allow the guide sections to rotate by weight of the rectangular sheet to thereby adjust a posture of the rectangular sheet and to automatically fall on the stacking section.

### Claim 2 (depends on 1)

A sheet receiving and stacking apparatus as claimed in claim 1, wherein said guide means comprises a body rotatably supported in a position off said stacking section, and the guide sections which are provided on said body and in contact with said rectangular sheet above said stacking section.

### Claim 3 (depends on 2)

A sheet receiving and stacking apparatus as claimed in claim 2, wherein said body of said guide means is a cylindrical member having a horizontal rotating shaft, and said guide section of said guide means is a plate-like member provided in parallel with said rotating shaft of said body on the outer peripheral surface of said body.

### Claim 4 (depends on 1)

A sheet receiving and stacking apparatus as claimed in claim 1, wherein said guide means includes two bodies, each body being rotatably attached to the side board, said guide sections being fixed to the body and rotating as the body rotates.

### Claim 5 (depends on 4)

A sheet receiving and stacking apparatus as claimed in claim 4, wherein each of said bodies and the guide sections attached thereto extend parallel to the stacking section to support the rectangular sheet parallel to the stacking section.
