The PTP tablet sheet 900 or the like is drawn into the chucking unit 400 along the rails 440a and 440b of the lateral guides 440 and 440. Accordingly, the posture of the PTP tablet sheet 900 or the like is controlled to be horizontal, so that the PTP tablet sheet 900 or the like falls into the primary bucket 450 while maintaining the horizontal state. In this case, unlike the conventional example, the primary bucket 450 does not clog because the next sheet overlaps with the uneven portions such as the inclined PTP tablet sheet 900, so that the primary bucket 450 can be downsized. .

  In the above embodiment, the two cassette shelves 600 and 600 are arranged on the left and right. However, the cassette shelves 600 and 600 may be arranged on the front and back, or one or three or more cassette shelves may be arranged. Good. In that case, it is preferable from the viewpoint of work efficiency that the number of carriages, chucking units, cutting units, and the like correspond to this.

  Moreover, in the said embodiment, since the space | interval of the rails 440a and 440b of the horizontal guides 440 and 440 is expanded, it takes time and work efficiency falls by that much.

  Therefore, for example, as shown in FIG. 8B, two contact members (corresponding to the contact plates) with which the left and right rear ends of the PTP tablet sheet 900 and the like can contact the rear part in the chucking unit 400. 440c and 440d are respectively provided, and the left and right rear ends of the PTP tablet sheet 900 and the like drawn into the chucking unit 400 are caused to collide with the contact members 440c and 440d with the inertial force generated by the drawing. The PTP tablet sheet 900 or the like may be configured to drop into the primary bucket 450 below the chucking unit 400.

  According to this, the posture control is performed so that the PTP tablet sheet 900 or the like is leveled by being chucked by the chuck 430 of the chucking unit 400 and pulled into the chucking unit 400. Is done. When the chucked 430 of the chucking unit 400 is released immediately before the horizontal PTP tablet sheet 900 or the like collides with the contact members 440c and 440d, the inertial force is applied. As a result of the horizontal movement of the PTP tablet sheet 900 and the like, it collides with the contact members 440c and 440d. Due to this collision, the PTP tablet sheet 900 or the like falls into the primary bucket 450 below the chucking unit 400 while maintaining its horizontal posture.

  Therefore, in this case, there is no need to increase the distance between the rails 440a and 440b of the lateral guides 440 and 440 as in the above embodiment, so that the work can be quickly collected in the primary bucket 450, and the work efficiency is greatly increased. Can be improved.

  In the above embodiment, the PTP tablet cassettes 500, 500,... Are arranged on the shelf plate 602 of the cassette shelf 600 in the width direction of the PTP tablet cassettes 500, 500,. However, the shelf plate is not limited to a stationary flat plate shape, and may be, for example, a cylindrical shape rotating around a predetermined axis. In that case, it is sufficient to move the chucking unit 400 relative to each PTP tablet cassette 500, 500,... Mounted on the rotating shelf.
