Abstract

The invention discloses a feeding device. The feeding unit (50) is provided with a deceleration roller (52), a holder part (94), a protruding part (132), a housing part (70), a pressing part (152), a first restricting part (172), and a second restricting part (176). The holder portion (94) rotatably holds the reduction roller (52). The protruding part (132) serves as a fulcrum for swinging of the holder part (94). The accommodating part (70) accommodates the holder part (94). The pressing part (152) presses the holder part (94). The first restricting section (172) restricts the movement of the holder section (94) in the retraction direction. The second restricting section (176) restricts the movement of the holder section (94) in the direction opposite to the retracting direction. The pressing part (152) is disposed so as to be offset in the Y direction with respect to a virtual line (G) passing through the midpoint of the protruding part (132) and the midpoint of the first restricting part (172). The holder part (94) is in contact with the first restricting part (172) and the second restricting part (176).

Description

technical field [0001] The present invention relates to a feeding device. Background technique [0002] The sheet conveying device of Patent Document 1 includes: a first holder that rotatably supports a deceleration roller; a second holder that accommodates the first holder; an accommodating portion that accommodates the second holder; and a separation assist spring that pushes upward the second holder is pressed; and the hook portion is engaged with the second holder. A protrusion is provided on the second holder so as to protrude. The protrusion of the second holder is fitted into the positioning recess of the accommodating portion from above. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2018-16458 [0004] In the sheet conveying device of Patent Document 1, in order to make the second holder detachable from the accommodating portion, the projection of the second holder is made to be movable upward. In addition, the second holder is configured to resist th...
