Sheet feeding mechanism and image forming apparatus

摘要

A sheet feeding mechanism is configured to feed a sheet, which has an actuator having a contact member configured to contact a sheet being fed, and a shaft configured to support the contact member, the shaft having a first end and a second end in a longitudinal direction, a first supporting part configured to support a first end portion of the shaft, a second supporting part configured to support a second end portion of the shaft, a detection unit configured to detect a position of the contact member, and an elastic supporting member configured to holds the first end portion of the shaft such that the shaft is displaceable in a direction perpendicular to the longitudinal direction.

1. A sheet feeding mechanism configured to feed a sheet along a sheet feed path, the sheet feeding mechanism comprising:
an actuator having a contact member configured to contact a sheet within a contact area of the sheet feed path, and a shaft configured to support the contact member such that the contact member is rotatable about the shaft, the shaft having a first end and a second end in a longitudinal direction; a first supporting part configured to support a first end portion of the shaft, wherein the first supporting part has a first shaft hole extending in a direction such that the first end of the shaft can move closer to or farther away from the sheet feed path, the first shaft hole having an end portion on a side closer to the sheet feed path; a second supporting part configured to support a second end portion of the shaft, wherein the second supporting part has a second shaft hole in which the shaft can be fitted; a detection unit configured to detect a position of the contact member; and an elastic supporting member configured to hold the first end portion of the shaft such that the shaft is displaceable in a direction perpendicular to the longitudinal direction;wherein the elastic supporting member biases the first end portion of the shaft in a direction toward the contact area of the sheet feed path to contact the end portion of the first shaft hole.
