Abstract
Abstract A recording apparatus records an image impression of an original on a sheet. The recording apparatus comprises a flip lever arranged to oppose a distal end of a first convey path for conveying the sheet recorded by a recording mechanism. The flip lever is movable between the first position where the sheet conveyed along the first convey path is guided in a second convey path and a second position where the sheet is guided in a third convey path. A temporary stacking tray is arranged to oppose a distal end of the second convey path and temporarily stacks the sheet guided by the flip lever from the first convey path to the second convey path while the first surface of the sheet faces upward. In front of the temporary stacking tray, an inverting mechanism is provided for conveying the sheet temporarily stacked on the temporary stacking tray to the third convey path through a fourth convey path without passing through the flip lever while the second surface opposing the first surface faces upward.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
237 words
A sheet inverting and collecting apparatus for stacking a sheet-like recording medium from a recording apparatus, comprising: means for defining first and second convey paths for the recording medium; a drive roller; a first driven roller in rolling contact with said drive roller, said first driven roller and said drive roller being provided with nip portions opposing a distal end of the first convey path; a second driven roller in contact with said drive roller, said second driven roller and said drive roller being provided with nip portions opposing the proximate end of the second convey path, said first convey path terminating into said second convey path; stacking means movable between a first position in which the recording medium is released from the nip portions of the drive and first driven rollers and a second position in which the trailing edge of the recording medium is brought in the nip portions of the drive and second driven rollers; said first and second driven rollers in continuous contact with said drive roller; driving means for moving the stacking means between the first and second positions; and sensing means provided in the first convey path, for sensing the passing of the trailing edge of the recording medium and operating and driving means after a predetermined period from the sensing of the passing of the trailing edge to bring the stacking means to the second position for a predetermined time.
Claim 2
Dependent Claim
237 words
A sheet inverting and collecting apparatus for stacking a sheet-like recording medium from a recording apparatus, comprising: means for defining first and second convey paths for the recording medium; a drive roller; a first driven roller in rolling contact with said drive roller, said first driven roller and said drive roller being provided with nip portions opposing a distal end of the first convey path; a second driven roller in contact with said drive roller, said second driven roller and said drive roller being provided with nip portions opposing the proximate end of the second convey path, said first convey path terminating into said second convey path; stacking means movable between a first position in which the recording medium is released from the nip portions of the drive and first driven rollers and a second position in which the trailing edge of the recording medium is brought in the nip portions of the drive and second driven rollers; said first and second driven rollers in continuous contact with said drive roller; driving means for moving the stacking means between the first and second positions; and sensing means provided in the first convey path, for sensing the passing of the trailing edge of the recording medium and operating and driving means after a predetermined period from the sensing of the passing of the trailing edge to bring the stacking means to the second position for a predetermined time.
Claim 3
Dependent Claim
22 words
The apparatus according to claim 1, wherein said stacking means includes a stacking tray positioned between the first and second convey paths.
Claim 4
Dependent Claim
28 words
The apparatus according to claim 2, wherein said stacking means includes a projection projected from the stacking tray to press the recording medium onto the second driven roller.
Claim 5
Dependent Claim
18 words
The apparatus according to claim 3, wherein said projection has a roller rotatably supported by the stacking tray.
Claim 6
Dependent Claim
33 words
The apparatus according to claim 1, further including means for sensing the position of the trailing edge of said recording medium in the vicinity of the distal end of said first convey path.
Claim 7
Dependent Claim
42 words
The apparatus according to claim 5, further including first time delay means connected to said sensing means for actuating movement of said stacking means from said first position to said second position after a predetermined time from detection of said trailing edge.
Claim 8
Dependent Claim
48 words
The apparatus according to claim 6, further including second time delay means for maintaining said stacking means in said second position for a fixed time sufficient to permit said trailing edge of said recording medium to pass through the nip portions of the drive and second driven rollers.
Claim 9
Dependent Claim
19 words
The apparatus according to claim 7, wherein said first and second time delay means are included within a micro-processor.
Claim 10
Dependent Claim
22 words
The apparatus according to claim 1, further including a stacking tray arranged to receive said recording medium from said second convey path.
Claim 11
Dependent Claim
48 words
The apparatus according to claim 9, which further comprises variable means for moving said stacking tray in a direction along a plane thereof between a first position where said stacking tray receives the recording medium at a predetermined position and a second position different from the first position.
Claim 12
Dependent Claim
47 words
The apparatus according to claim 10, wherein said variable means comprises a drive source for driving said stacking tray, said inverting means comprises driving means for respectfully driving said drive roller and first and second driven rollers, said driving means being provided with a common drive source.
Claim 13
Dependent Claim
16 words
The apparatus according to claim 9, wherein said stacking tray is movable along a predetermined direction.
