| 摘要 | A paper feed device includes a paper stacking shelf, a paper trailing edge guide that regulates a position of a paper bundle, a contact member that is disposed on the paper trailing edge guide, and a position switch portion that moves the contact member to either a withdrawn away position or a contact position with respect to an upper face of the paper bundle. The position switch portion is provided with a rod that is moved in conjunction with an operation for causing the paper feed device to be pulled out from and pushed into the accommodation space, and a rotatable member that is rotated in conjunction with the movement of the rod. The position switch portion supports the contact member, and causes the contact member to be rotationally moved to either the withdrawn away position or the contact position in conjunction with the rotation of the rotatable member. | ||
