Conveying apparatus and printing apparatus

A conveying apparatus, comprising:

• a conveyance roller configured to convey a sheet in a conveyance direction along a conveyance path;
• a frame including:
• a guide member extending in a first direction intersecting with the conveyance direction;
• and
• support members arranged at both end sides in the first direction of the conveyance path and having first long holes respectively, each of the first long holes being extended in a second direction intersecting with the conveyance direction and the first direction;
• side guides arranged between the support members and having second long holes being extended in the second direction respectively, the side guides being movable in the first direction along the guide member;
• a shaft inserted into the first long holes and the second long holes;
• a lever fixed to the shaft;
• and
• an elastic member configured to urge the shaft toward the guide member,
• wherein each of the second long holes has a tapered portion,
• a dimension in the conveyance direction of the tapered portion decreases toward the guide member as compared with a dimension in the conveyance direction of the shaft, and
• the lever is configured to rotate between a first rotational position to apply urging force of the elastic member to the shaft and a second rotational position to retain the shaft at a position away from the tapered portion against the urging force of the elastic member.

A conveying apparatus, comprising:

• a conveyance roller configured to convey a sheet in a conveyance direction along a conveyance path;
• a guide member extending in a first direction intersecting with the conveyance direction;
• side guides arranged to be apart from each other in the first direction, the side guides being movable in the first direction along the guide member;
• and
• an interlock mechanism configured to interlock movement of the side guides in the first direction,
• wherein the interlock mechanism includes:
• first rack gears connected to the side guides respectively and extending from the side guides inwardly in the first direction;
• second rack gears overlapped with the first rack gears respectively in a second direction intersecting with the conveyance direction and the first direction, the second rack gears being movable in the first direction between a first position and a second position, the second rack gears being in phase with the first rack gears in the first position, the second rack gears being out of phase with the first rack gears in the second position;
• a pinion gear configured to mesh with the first rack gears and the second rack gears;
• and
• an elastic member configured to urge the second rack gears toward the second position with respect to the first rack gears.
