Transport unit (200, 400, 800, 1000) for a device for handling notes of value, having a first transport path limiting element (202, 1006) and a second transport path limiting element (204, 1008), which are arranged and spaced apart relative to each other such that a transport path (206, 1004) is formed between the transport path limiting elements (202, 204, 1006, 1008) and notes of value can be transported along the transport path (206, 1004), having at least one sensor (210, 1010), which is designed to identify at least one security feature of the notes of value transported along the transport path (206, 1004), having at least one guide element (208, 1002), which is movably arranged and can be moved at least between two positions, wherein, in a first position, the guide element (208, 1002) is at least partially arranged in the transport path (206, 1004) and is designed to limit the height of the transport path (206, 1004) in a detection region of the sensor (210, 1010) to a first distance and, in a second position, the guide element (208, 1002) is not arranged in the transport path (206, 1004), wherein the first transport path limiting element (202, 1006) is at a distance in a range of from 2 mm to 4 mm from the second transport path limiting element (204, 1008) in a first transport path region arranged upstream of the detection region in the transport direction (P1, P2), and wherein the first transport path limiting element (202, 1006) is at a distance in a range of from 1 mm to 2 mm from the second transport path limiting element (204, 1008) in a second transport path region arranged downstream of the detection region in the transport direction (P1, P2). having a first transport path limiting element (202, 1006) and a second transport path limiting element (204, 1008), which are arranged and spaced apart relative to each other such that a transport path (206, 1004) is formed between the transport path limiting elements (202, 204, 1006, 1008) and notes of value can be transported along the transport path (206, 1004), having at least one sensor (210, 1010), which is designed to identify at least one security feature of the notes of value transported along the transport path (206, 1004), having at least one guide element (208, 1002), which is movably arranged and can be moved at least between two positions, wherein, in a first position, the guide element (208, 1002) is at least partially arranged in the transport path (206, 1004) and is designed to limit the height of the transport path (206, 1004) in a detection region of the sensor (210, 1010) to a first distance and, in a second position, the guide element (208, 1002) is not arranged in the transport path (206, 1004), wherein the first transport path limiting element (202, 1006) is at a distance in a range of from 2 mm to 4 mm from the second transport path limiting element (204, 1008) in a first transport path region arranged upstream of the detection region in the transport direction (P1, P2), and wherein the first transport path limiting element (202, 1006) is at a distance in a range of from 1 mm to 2 mm from the second transport path limiting element (204, 1008) in a second transport path region arranged downstream of the detection region in the transport direction (P1, P2).
