1. A coin counting apparatus allowing a bad coin to be sorted, comprising:
a coin separation unit installed on a support frame and including a coin sorting part in which a plurality of coin sorting holes for sorting coins according to sizes of the coins are formed in a circumferential direction and a coin separation plate on which a coin guide portion for guiding the coins to the coin sorting part is formed;
a bad coin discharge unit installed in the coin guide portion of the coin separation unit and configured to detect whether the coin moving to be sorted is a bad coin and sort the bad coin;
a coin supply unit configured to supply the sorting target coins to be sorted and moved along the coin guide portion;
a coin transfer unit elastically pressed against the coin separation unit and configured to move the coin input from the coin supply unit to the coin guide portion and the coin sorting holes in a state in which the coins are pressed against the coin separation plate;
coin collection containers installed on the support frame under the coin sorting holes of the coin separation plate to stack the coins passing through the coin sorting holes, the coin collection containers having cylindrical shapes;
a coin stack and change discharge unit installed between the frame and a slider support frame, the coin stack and change discharge unit being configured to count the coins stacked in the coin collection container and discharge change;
a slider, which is slid on a guide rail to open or close a lower surface of each of the coin collection containers and to discharge one coin when moving forward and rearward, the slider being formed on a lower surface of the support frame on which the coin collection containers are installed; and
a forward-rearward movement drive part configured to move the slider forward and rearward installed on the slider support frame, the forward-rearward movement drive part including:
a guide long hole formed in a guide rail portion corresponding to a lower surface of the slider in a longitudinal direction of the slider;
pin support protrusions installed spaced apart from each other on the lower surface of the slider in a direction toward the guide long hole;
a pin support portion formed between the pin support protrusions;
a rotation link installed on the support frame corresponding to the pin support portion and supported by a hinge shaft to be rotatable in a direction in which the guide long hole is formed;
a long hole formed in the rotation link in a longitudinal direction thereof;
a pin inserted into the pin support portion is formed on an end portion of the rotation link;
a motor installed to correspond to the long hole on the support frame; and
an eccentric cam on which a rotation pin to be inserted into the long hole of the rotation link is formed is installed on a drive shaft of the motor.
