Cassette drawing-in device and sheet supply device

A sheet supply device, comprising:

• a cassette drawing-in device disposed on a second side in a first direction of a cassette, the cassette drawing-in device comprising:
• a lever configured to rotate around a rotation axis parallel to a first direction and including an engaging groove opened on a first side in the first direction, the engaging groove including an entrance for a cassette pin at an end portion in a longitudinal direction, the cassette pin projecting to a second side, which is an opposite side of the first side, in the first direction from the cassette, the cassette configured to move in a second direction orthogonal to the first direction, the lever rotating around the rotation axis to thereby draw in, in the second direction, the cassette pin engaging in the engaging groove,
• a guide section formed in the entrance of the engaging groove and configured to guide the cassette pin to the first side in the first direction, and
• an urging member configured to urge the lever to the first side in the first direction;
• the cassette configured to store sheets;
• and
• a housing configured to support the cassette movable in the second direction.

A method, comprising:

• rotating a lever of a cassette drawing-in device around a rotation axis parallel to a first direction, the lever including an engaging groove opened on a first side in the first direction, the engaging groove including an entrance for a cassette pin at an end portion in a longitudinal direction, the cassette pin projecting to a second side, which is an opposite side of the first side, in the first direction from a cassette;
• moving the cassette in a second direction orthogonal to the first direction, the lever rotating around the rotation axis to thereby draw in, in the second direction, the cassette pin engaging in the engaging groove;
• guiding the cassette pin to the first side in the first direction using a guide section formed in the entrance of the engaging groove;
• and
• urging the lever to the first side in the first direction.
