Abstract: A currency detector having a side flip cover, comprising a main body (10) and an upper cover (20). A data line is connected between the main body (10) and the upper cover (20); a currency detection channel is formed between the upper cover (20) and the main body (10); a side edge of the upper cover (20) is connected to the main body (10) in a flippable manner; the data line connected between the upper cover (20) and the main body (10) is arranged on the side of the upper cover (20) connected to the main body (10). Because the side edge of the upper cover (20) is connected to the main body (10) in the flippable manner, the upper cover (20) can be flipped leftwards and rightwards, thereby meeting maintenance requirements of the currency detector; moreover, because the connection between the upper cover (20) and the main body (10) avoids the currency detection channel, a connection position can be arranged just along one side of the currency detection channel, and the currency detector can be arranged to be thinner and smaller, thereby achieving miniaturization of the currency detector. Because the upper cover (20) is configured to be flipped leftwards and rightwards, and the data line connected between the upper cover (20) and the main body (10) can be arranged on the side of the upper cover (20) connected to the main body (10), in a flipping process of the upper cover (20), the data line only swings along with the upper cover (20) and will not be stretched, thereby reducing the exposure amount of the data line, effectively preventing the data line from being damaged, and ensuring stability of communication between the upper cover (20) and the main body (10).
