Sheet conveyor and image reading apparatus

A sheet conveyor comprising:

• a conveying path along which a sheet is conveyed;
• a transparent member comprising a surface facing the conveyed path;
• and
• a guide member comprising a downstream continuous edge line which extends continuously and is disposed at a downstream end of the guide member, such that a distance from the downstream continuous edge line to a reference line varies in a direction in which the reference line extends,
• wherein the reference line is parallel to the surface of the transparent member and is perpendicular to the conveying direction,
• wherein the distance from the downstream continuous edge line to the reference line varies continuously in the direction in which the reference line extends, and
• wherein the distance from the center of the downstream continuous edge line to the reference line is a minimum distance.

A sheet conveyor comprising:

• a conveying path along which a sheet is conveyed;
• a transparent member comprising a surface facing the conveyed path;
• and
• a guide member comprising a downstream continuous edge line which extends continuously and is disposed at a downstream end of the guide member, such that a distance from the downstream continuous edge line to a reference line varies in a direction in which the reference line extends,
• wherein the reference line is parallel to the surface of the transparent member and is perpendicular to the conveying direction, and
• wherein the height of the downstream continuous edge line at a point at which the distance from the downstream continuous edge line to the reference line is a maximum distance is less than or equal to the height of the surface of the transparent member.

A sheet conveyor comprising:

• a conveying path along which a sheet is conveyed in a conveying direction;
• a transparent member comprising a surface facing the conveying path;
• and
• a guide member comprising a downstream continuous edge line which extends continuously and is disposed at a downstream end of the guide member with respect to the conveying direction, such that a distance from the downstream continuous edge line to a reference line varies in a direction in which the reference line extends,
• wherein the reference line is parallel to the surface of the transparent member and is perpendicular to the conveying direction,
• wherein the guide member is disposed at an upstream end of the transparent member.
