摘要： A sheet feeding apparatus having a feeding roller for feeding a sheet, a support shaft forwardly and reversely rotatable integrally with the feeding roller and a stopper disposed upstream of the feeding roller in the sheet feeding direction for temporarily regulating the feed of a sheet to the feeding roller. When the rotation in one direction of the feeding roller is transmitted to a locking member through a one-way clutch, the locking member is rotated to lock the stopper. When the feeding roller is rotated in the opposite direction, the locked state of the stopper is released.

摘要： An image-forming machine comprises a sheet member conveying passage extending through a transfer zone and a fixing zone, a sheet member-feeding means for feeding a sheet member onto the sheet member conveying passage, and a sheet member conveying means for conveying the sheet member through the sheet member conveying passage. A housing of the image-forming machine has a lower surface defined by an intermediate lower wall and an upper surface defined by an intermediate upper wall, and forms a space of which the front surface is opened. The downstream end portion of the sheet member conveying passage extends along a one side portion of the intermediate lower wall on the lower side thereof. The one side portion of the intermediate lower wall is defined by the opening/closing member, and opening/closing member is brought to the open position to open the downstream end portion of the sheet member conveying passage. The sheet member conveying means includes a pair of register rollers. After the leading edge of the sheet member delivered onto the sheet member conveying passage is brought into contact with the nip of the pair of register rollers, the pair of register rollers are preliminarily rotated for only a predetermined period of time.
