  • Also disposed above the incoming transport section 150 are second direction detection sensors 156 for detecting whether or not both ends of the tablet cassette 20 are positioned directly above the incoming transport belt 151 .
  • the second direction detection sensor 156 is a laser-type detection means that is arranged at both ends of the transport path of the input transport section 150 and passes directly downward, and when the tablet cassette 20 passes directly below it, if both sensors detect its passage at the same time (both are ON), it can detect that the tablet cassette 20 is moving perpendicular to the transport direction as shown in Figure 6. Conversely, as shown in Figure 7, if the tablet is placed incorrectly, the light emitted by the first direction detection sensor 155 is blocked by the tablet cassette 20 and turns OFF, making it possible to detect the incorrect placement direction.
  • the first direction detection sensor 155 is likely to turn OFF because it is blocked by the tablet cassette 20.
  • the first direction detection sensor 155 happens to be tilted only to the extent that it can pass, by arranging a pair of second direction detection sensors 156 on both sides of the incoming conveyor belt 151, it is possible to determine whether or not the tablet cassette 20 is moving parallel to the conveyor direction based on whether or not each of the second direction detection sensors 156 turns ON within a predetermined time interval.
  • FIG. 8 is a schematic example of a case where the inclination with respect to the transport direction is large, in reality, the difference in timing at which the two second direction detection sensors 156 are blocked may not be as large as the inclination shown in the figure.
  • first direction detection sensor 155 or second direction detection sensor 156 will be turned OFF, detecting that tablet cassette 20 is not being conveyed in the correct posture. Conversely, when both the first direction detection sensor 155 and the second direction detection sensor 156 are ON, the control unit 550 determines that the tablet cassette 20 placed on the incoming conveyor belt 151 is placed in the correct position.
  • the transport arm units 110 are arranged on both sides of the drug transport/dispensing device 500 with their respective grip units 113 facing inward, so that the tablet cassette 20 is transported to the receiving/storage section 154 in the correct position with the handle portion 29 facing outward in the receiving/transporting section 150, allowing the grip unit 113 to grasp and move the handle portion 29 of the tablet cassette 20.
