1. A coin processing device comprising:
a feed belt configured to normally rotate in contact with an upper side of a coin, which is fed from a rotating disk, to convey the coin to a conveyance passage extending from an inlet-side passage portion to an outlet-side passage portion;
a conveyance motor configured to normally rotate the feed belt during the normal rotation;
a detection unit configured to detect the coin passing through a position determined in advance in the conveyance passage; and
a control unit configured to switch the conveyance motor from a usual normal rotation state where the conveyance motor normally rotates at a usual normal rotation speed to a first slow normal rotation state where the conveyance motor normally rotates at a first slow normal rotation speed slower than the usual normal rotation speed, and configured to switch the conveyance motor from the first slow normal rotation state to a second slow normal rotation state where the conveyance motor normally rotates at a second slow normal rotation speed slower than the first slow normal rotation speed, in response to detection of the coin by the detection unit, and then rotates the conveyance motor,
wherein the control unit is configured to
perform batch processing in which the control unit conveys a predetermined numbers of the coins of a predetermined denomination set to the outlet-side passage portion,
switch the conveyance motor from the usual normal rotation state to the first slow normal rotation state in response to the detection unit detecting a last coin of the predetermined numbers of the coins subject to the batch processing,
switch the conveyance motor from the first slow rotation state to the second slow rotation state in response to the detection unit detecting a coin to be stopped following the last coin subject to the batch processing in a case where the coin to be stopped is conveyed on the conveyance passage following the last coin,
after switching the conveyance motor from the first slow rotation state to the second slow rotation state, stop the conveyance motor in response to the detection unit changing from detecting the coin to be stopped to not detecting the coin to be stopped so that the control unit causes the coin to be stopped to stop at an end portion on a downstream side of the outlet-side passage portion, and
thereafter reversely rotate the conveyance motor to perform conveyance of the coin to be stopped toward an upstream side opposite to the downstream side so as to return the coin to be stopped to the rotating disk.
