There is provided a winding device, including: a winding part that winds a longitudinal recording medium in which an image is formed: a suppressing member that suppresses generation of a strain in the longitudinal recording medium wound by the winding part; and an operation part that operates the suppressing member in a case where the strain in the longitudinal recording medium wound by the winding part is a threshold value or more.

A spring is located between a separation pad and a frame. The frame is configured to receive a downward reaction force that is a reaction force of an urging force of a spring. A rotation shaft and a contact piece are located at one side of the separation pad in a width direction. The frame has an upper edge in a first region defined between one end and another end of the rotation shaft in the width direction. A height of the upper edge in the first region is at a same height or below a rotation axis. The frame includes a standing wall in a second region in the width direction. The standing wall extends farther upward than the upper edge in the first region. The second region includes a region in which the separation pad is located. The second region is other than the first region.

A sheet conveying device includes a drive roller, a driven roller, a guide, and a pressure mechanism. The drive roller rotates to convey a sheet in a sheet conveyance path. The driven roller is driven by the drive roller to rotate and convey the sheet in the sheet conveyance path with the drive roller. The guide has a center of rotation coaxially disposed with a center of rotation of the driven roller. The guide is rotated between a guide position and an open position, guides the sheet conveyed in the sheet conveyance path at the guide position, and opens open the sheet conveyance path at the open position. The pressure mechanism is disposed on the guide to press the driven roller to the drive roller in a pressure direction at a given contact pressure. The driven roller moves relative to the drive roller in an orthogonal direction to the pressure direction in conjunction with the guide rotating.

When a user opens an opening/closing portion for accessing an inside of a housing, a shaft member is displaced in a +Z direction by a biasing force of a spring, and moves a lever member in the +Z direction. A rotation shaft rotates in a + direction along with displacement of the shaft member in the +Z direction. As a result, a cam rotates in the + direction together with the rotation shaft, and presses, by a projection portion, a cam reception portion of an arm unit main body in a X direction against the biasing force of the spring. Due to this, the cam rotates the arm unit main body in a direction. Then, a driven roller moves the +Z direction along with rotation of the arm unit main body in the direction, and is switched from a nip state to a non-nip state.
