Abstract: The degrees of freedom are increased for the layout for a member (for example, an upper guide or the like that restricts an up-down direction position of a medium) to be disposed above a storage space for storing a paper sheet-shaped medium, and a disposable space for the member is enlarged. A medium storage box having an internal storage space for storing a paper sheet-shaped medium includes an upper installation member (for example, a lid section) that is disposed above the storage space, and a liquid ejection mechanism that ejects liquid from a liquid ejection nozzle. A liquid ejection direction of the liquid ejection nozzle is set in a direction toward a lower face of the upper installation member.

Abstract: A medium storage box includes an internal storage space configured to store a paper sheet-shaped medium. The medium storage box includes: a first opening into which an insertion member is inserted from outside; a second opening through which the medium passes; a first shutter member that closes off the first opening; a second shutter member that closes off the second opening; and a biasing mechanism that biases either the first shutter member, or the second shutter member, or both, in a closing direction. The first shutter member is configured to be pressed by the insertion member and moves in an opening direction during insertion of the insertion member, such that a portion of the first shutter member abuts the second shutter member and moves the second shutter member in an opening direction.

Abstract: A reject storage box is provided with a sufficiently thick cover body above a second storage space that stores banknote bundles W that a user has forgotten to take, and a guide space is provided penetrating the cover body in an oblique direction. In the reject storage box, when a banknote bundle falls into an intake hole from above, a lower face of the banknote bundle immediately contacts a position toward the top of a main guide face, and the banknote bundle W travels downward through the guide space with the lower face of the banknote bundle W sliding against the main guide face. The reject storage box thereby enables the banknote bundle dropping downward through the guide space to be maintained in a substantially uniform orientation, and ultimately enables the banknote bundle to be stacked neatly inside the second storage space.
