Abstract:
A manual feed tray includes a tray body and a lift unit, and the lift unit includes a lift plate, a lift spring and a pair of cursors. The cursor includes a guide portion. When the manual feed tray is closed from a sheet feeding state of the lift plate, the guide portion comes into contact with a facing wall portion, whereby a downstream side of the lift plate in a covering direction moves downward. Thus, even if the manual feed tray is closed with the lift plate moved upward, the lift plate smoothly moves downward.

Claim (Index 1):
An image forming apparatus, comprising:\n an apparatus body; an image forming unit arranged in the apparatus body and configured to form an image on a sheet; a manual feed tray supported openably and closably with respect to a side surface of the apparatus body and including a sheet placing portion on which the sheet is to be placed in an open state with respect to the apparatus body; a sheet feed roller provided in the side surface and configured to convey the sheet placed on the manual feed tray in a predetermined conveying direction; and a pair of facing wall portions arranged both sides of the sheet feed roller in a sheet width direction orthogonal to the conveying direction in the side surface and arranged to face the manual feed tray in a closed state of the manual feed tray with respect to the side surface; wherein the manual feed tray includes:\n a tray body constituting the sheet placing portion; \n a lift plate arranged on a downstream side of the tray body in the conveying direction and supported swingably on the tray body to bring a downstream part of the sheet in the conveying direction into contact with the sheet feed roller; \n a biasing member arranged between the lift plate and the tray body and configured to bias the lift plate so as to bring the sheet placed on the sheet placing portion into contact with the sheet feed roller; and \n a pair of cursors supported on the lift plate and configured to restrict a position of the sheet in the sheet width direction; \n the lift plate includes a pair of pivot portions arranged on an upstream side in the conveying direction and supported on the tray body, the lift plate being swingable in directions toward and away from an upper surface of the tray body about the pair of pivot portions; at least one of the pair of cursors includes a pressed portion which is formed on a downstream end part of the cursor and arranged with a predetermined interval between the facing wall portion and the pressed portion in a sheet feeding state where the downstream part of the lift plate is moved upward with the manual feed tray in the open state; and the downstream part of the lift plate moves in the direction toward the upper surface of the tray body against a biasing force of the biasing member by the contact of the pressed portion with the facing wall portion when the manual feed tray is closed in the sheet feeding state.
