シート供給装置及び画像形成装置
Document Type and Number:
Japanese Patent JP7435256
Kind Code:
B2
Abstract:
A sheet feeding device (10) comprising: a circuitry (50) which causes a rotation driver (12) to rotate a spool (8) in a winding direction to determine a timing at which a signal change rate exceeds a change rate threshold as a passing time at which a leading end of a continuous sheet (P) passes through a leading end sensor (16), causes the rotation driver (12) to rotate the spool (8) by a rotation angle (θ) in the winding direction, from the passing time, to position the leading end of the continuous sheet (P) at a feeding start position, rotates the spool (8) in a feeding direction to feed the continuous sheet (P) from the feeding start position along a guide portion (13b) and changes the change rate threshold based on an outer diameter (D) of a roll (9).
