Image processing apparatus

A sheet feed cassette operating mechanism, comprising:

• a sheet feed cassette insertable into a main body;
• a pull-in member configured to pull in the sheet feed cassette to the main body from a pull-in start position to a pull-in complete position;
• and
• a biasing member configured to bias the pull-in member in an insertion direction, wherein a biasing force in a state where the pull-in member is at a first position closer to the pull-in complete position than the pull-in start position is larger than a biasing force in a state where the pull-in member is at a second position closer to the pull-in start position than the first position, wherein
• the pull-in member comprises a first connecting portion to which the biasing member is connected, is rotatable around a first axis line along a first axis direction perpendicular to the insertion direction of the sheet feed cassette with respect to the main body, and presses the sheet feed cassette in the insertion direction by rotating in the first rotational direction from the pull-in start position to the pull-in complete position, and
• as viewed from the first axis direction, when an angle formed by a direction of the biasing force of the biasing member exerted on the first connecting portion and a line segment passing through the first axis line and the first connecting portion is defined as θ1, the θ1 is an acute angle in at least a portion of a state where the pull-in member is between the pull-in start position and the pull-in complete position, and the θ1 increases as the pull-in member moves from the pull-in start position toward the pull-in complete position.

An image processing apparatus, comprising:

• an apparatus main body;
• a sheet feed cassette insertable into the apparatus main body;
• a pull-in member configured to pull in the sheet feed cassette to the apparatus main body from a pull-in start position to a pull-in complete position;
• a biasing member configured to bias the pull-in member in an insertion direction, wherein a biasing force in a state where the pull-in member is at a first position closer to the pull-in complete position than the pull-in start position is larger than a biasing force in a state where the pull-in member is at a second position closer to the pull-in start position than the first position;
• an intermediate lever rotatable around a second axis line along a second axis direction perpendicular to the insertion direction with respect to the apparatus main body and biased toward the pull-in member by the biasing member;
• and
• an auxiliary biasing member configured to bias the intermediate lever in a direction opposite to the biasing direction by the biasing member, wherein
• a torque applied to the intermediate lever by the auxiliary biasing member increases as the pull-in member moves from the pull-in start position toward the pull-in complete position.
