This design is for a slot intended to mitigate the inconvenience caused by the separation of the slots for bills and coins in a vending machine. In the existing slot, as coins are put into in one direction so they are likely to be returned or popped out when pushed into the hole. Thus, PLUS SLOT by which two slots are put together is suggested. The vending machine with plus(+)-shaped slots has one hole for both bills and coins.
