Abstract: An input apparatus of the invention can selectively receive at least one sheet medium or an envelope containing a sheet medium therein. The apparatus includes a transfer path for transferring at least one medium and an envelope, a width guide disposed in the transfer path to restrict a width of the transfer path according to one selection among media input and envelope input, and a separation device situated adjacent to the transfer path. The width guide sets a media transfer width in the transfer path when the media input is selected, and the width guide leaves the transfer path when the envelope input is selected. The separation device transfers the at least one medium and the envelope, and moves in a direction to increase the thickness of the transfer path to allow the envelope to pass through the transfer path when the envelope input is selected.

Abstract: A medium or bill reserving apparatus of the invention receives and reserves at least one individually transferred medium or bill, and discharges the reserved media in a batch. The apparatus is formed of an accumulating wheel having an outer surface and a groove portion opened in the outer surface to receive a tip of the medium for holding. The accumulating wheel is rotated from a medium standby position to a medium release position. A clamper is formed in the accumulating wheel to clamp the tip of the medium introduced into the groove portion and to release the medium at the medium release position, and a medium-accumulating section is formed outside the accumulating wheel for accumulating the medium released at the medium-release position.
