<p>[Problem] To prevent a movable blade from interfering with a sheet during movement of the movable blade to an open position after cutting the sheet with the movable blade, thereby preventing the sheet from being curled up and jammed from as a result of being hooked on the movable blade. [Solution] A sheet feeding device includes a moving mechanism (20) configured to move the cutting edge (Ba) of the movable blade (B) away from the cutting edge (Aa) of the fixed blade A to move the cutting edge (Ba) of the movable blade (B) from an open position (X) where the fed sheet (S) is received and to place the cutting edge (Ba) of the movable blade (Ba) at the open position; a biasing mechanism (35) that biases the movable blade (B) toward the fixed blade (A) so that the cutting edge (Ba) of the movable blade (B) can slide against the cutting edge (Aa) of the fixed blade (A); a spacing mechanism (40) configured to make the movable blade (B) away from the fixed blade (A) against a biasing force of the biasing mechanism (35) during a process of allowing the movable blade (B) to reach the open position (X) after cutting of the sheet S with the movable blade (B). The spacing mechanism (40) includes a cam (41) provided on the fixed blade (A) side and a cam follower (42) in contact with the came (41) provided on the movable blade (B) side.</p> |
