A sheet discharging apparatus includes a discharge portion discharging a sheet in a discharge direction; a sheet supporting portion including a support surface which supports a lower surface of the sheet discharged from the discharge portion; and a conductive portion which is electrically conductive and connected to a ground potential. The conductive portion is provided at the support surface.

A sheet storage apparatus having: a holding section that holds a storage bag for storing a sheet; a first clamping section; and a second clamping section, wherein the first clamping section and the second clamping section relatively approach to clamp the storage bag held by the holding section, and when a direction in which the first clamping section relatively approaches the second clamping section is defined as a first direction, and a direction opposite to the first direction is defined as a second direction, an end of the first clamping section in the first direction is located on a side in the first direction with respect to an end of the second clamping section in the second direction in a state in which the storage bag is clamped between the first clamping section and the second clamping section.

A medium processing apparatus includes a printer, a supporting member having a sheet-like shape and configured to support a discharged medium, and a winding unit configured to wind the supporting member and move with respect to the printer. The winding unit has a first case and a second case that rotatably support a winding shaft, and a placement portion placed at a flat surface. The first case and the second case in a state where axis lines of respective bearing portions that support the winding shaft are aligned with each other and in a state of being held so as to be mutually non-rotatable in a plane orthogonal to an axis line of the winding shaft, and when the winding unit is installed on a flat surface, the placement portion contacts the flat surface.

A sheet discharging apparatus includes a discharge unit, a stacking portion and a swing guide. The stacking portion includes an upstream supporting portion, a wall surface portion, a first supporting portion provided downstream of the upstream supporting portion and including a first inclined surface, and a second supporting portion provided downstream of the upstream supporting portion and including a second inclined surface. The swing guide is configured to overlap with the first supporting portion as viewed in a width direction of a sheet in a case where the swing guide is not in contact with a sheet discharged by the discharge unit, and swing upward in a case where the swing guide is pushed by a sheet. As viewed in the width direction, the stacking portion is configured to satisfy L1<L2, L4<L2, H1<H2, and H4<H2.

A tray device includes a first tray including a first surface and an abutting portion, and a second tray including a second surface and an abutted portion. The second tray is configured to move with respect to the first tray. The abutting portion includes two abutting surfaces located obliquely with respect to an extending direction of the first surface. The abutted portion includes two abutted surfaces located obliquely with respect to an extending direction of the second surface. A difference between an angle formed by each of the two abutting surfaces and the extending direction of the first surface and an angle formed by each of the two abutted surfaces and the extending direction of the second surface is set larger than a maximum angular difference between the extending direction of the first surface and a movement direction in which the second tray moves with respect to the first tray.
