A coin-roll ejecting device comprising: a storing unit having a bottom surface that is inclined with respect to a horizontal plane to store thereon a plurality of rolls of coins in a piled-up manner and along a rolling direction parallel to the inclined bottom surface, the storing unit having an ejecting mechanism that is configured to eject the rolls of coins one by one from near a side of the bottom surface that is at a lower level with respect to a vertical direction; a first detecting unit that is configured to detect each of the rolls of coins ejected from the storing unit; and a controlling unit that is configured to control the ejecting mechanism, wherein the ejecting mechanism includes a rotating member that is configured to rotate around a rotation axis that extends horizontally and orthogonally to the rolling direction parallel to the inclined bottom surface of the storing unit and has at least two notches each configured to receive one roll of coins stored in the storing unit, a driving unit that is configured to rotate the rotating member around the rotation axis, and a rotating position detecting unit that is configured to detect a rotating position of the rotating member, wherein the driving unit is capable of rotating the rotating member in both of a forward direction and a reverse direction, the forward direction being a rotation direction in which the rotating member rotates to eject the rolls of coins from the storing unit, and the reverse direction being the reverse of the forward direction, wherein the controlling unit controls the driving unit so as to rotate the rotating member in the reverse direction when the first detecting unit detects that the rolls of coins of a predetermined number have been ejected by the rotation of the rotating member in the forward direction and the rotating position detecting unit detects that the rotating member is positioned in a first predetermined position during ejecting the rolls of coins from the storing unit by the ejecting mechanism, the first predetermined position referring to a position at which a roll of coins remains in a notch of the notches of the rotating member after the rolls of coins of the predetermined number are ejected by the ejecting mechanism, and thereafter, the controlling unit controls the driving unit so as to stop the rotation of the rotating member when the rotating position detecting unit detects that the rotating member is positioned in a second predetermined position where the notch of the notches of the rotating member with the roll of coins received therein faces the storing unit. a storing unit having a bottom surface that is inclined with respect to a horizontal plane to store thereon a plurality of rolls of coins in a piled-up manner and along a rolling direction parallel to the inclined bottom surface, the storing unit having an ejecting mechanism that is configured to eject the rolls of coins one by one from near a side of the bottom surface that is at a lower level with respect to a vertical direction;
