SHEET CONVEYING DEVICE AND IMAGE READING APPARATUS

摘要

A sheet conveying device includes a conveyor for conveying a sheet along a predetermined conveyance path and a feeder unit for supporting the sheet to be fed to the conveyor. The conveyor includes a first guide part for guiding the sheet toward a downstream side in the conveying direction in a direction inclined at a downward gradient, a second guide part for guiding the sheet from the first guide part toward a further downstream side in a direction inclined at an upward gradient, a suction roller arranged at the first guide part for conveying the sheet supported by the feeder unit toward the downstream side, and a first conveyance roller arranged at the second guide part and for conveying the sheet conveyed by the suction roller toward the downstream side one at a time.

主权项

1. A sheet conveying device comprising:
a conveyor configured to convey a sheet along a predetermined conveyance path; and a feeder configured to support the sheet to be fed to the conveyor, wherein the conveyor comprises:
a first guide surface configured to guide the sheet, which is conveyed from a vicinity of a downstream end of the feeder in a conveying direction toward a further downstream side in the conveying direction, the first guide surface having a downstream end and an upstream end, wherein the first guide surface extends a downward gradient such that the downstream end is lower than the upstream end;a second guide surface configured to guide the sheet, which is conveyed from a vicinity of the downstream end of the first guide surface in the conveying direction toward a further downstream side in the conveying direction, the second guide surface having an upstream end and a downstream end, wherein the second guide surface extends at an upward gradient such that the upstream end is lower than the downstream end, and wherein an intersection of a first virtual plane including the first guide surface and a second virtual plane including the second guide surface form a specific portion, the specific portion being the lowest position in the conveyance path configured by the first guide surface and the second guide surface in an upper-lower direction; anda first conveyance roller disposed at a position facing the second guide surface, the first conveyance roller being configured to rotate about a first axis and separate the sheet conveyed by the suction roller one at a time and to convey the sheet toward the downstream side in the conveying direction, wherein the first axis is positioned at the downstream side of the specific portion in the conveying direction.
