Although the spring members 449a and 449a elastically supported at one point (4495) are provided, the tablet sheet 900 easily tilts in the front-rear direction between the rails 440a and 440b.

  In this regard, in the present embodiment, as shown in FIG. 7B, the PTP tablet sheet 900 pulled between the rails 440a and 440b at the rear portions 4493 of the rails 440a and 440b of the lateral guides 440 and 440. Since the spring members 449 and 449 that elastically support the left and right ends at two points (4491 and 4492), respectively, the PTP tablet sheet 900 does not tilt in the front-rear direction between the rails 440a and 440b. The PTP tablet sheet 900 can be held horizontally. Note that the spring members 449 and 449 may perform elastic support at three or more points.

  Hereinafter, the change of the chucking position of the PTP tablet sheet 900, which is a feature of the present invention, will be described in detail. 8A to 8D are explanatory views sequentially showing steps of changing the chucking position of the PTP tablet sheet 900 by the chucking unit 400. FIG.

  As shown in FIGS. 6A to 6C and FIG. 8A, the PTP tablet sheet 900 chucked by the chuck 430 and pulled to the front of the tablet cassette 500 is retracted from the support member 435. Thus, the guides are guided between the rails 440 a and 440 b of the lateral guides 440 and 440 while being chucked by the chuck 430. At this time, the interval between the rails 440a and 440b is set to be slightly wider than the width dimension of the PTP tablet sheet 900.

  Then, as shown in FIG. 8B, the backward movement of the support member 435 is stopped, so that the PTP tablet sheet 900 chucked by the chuck 430 is positioned at the intermediate position in the front-rear direction of the rails 440a and 440b. Then, posture control is performed so as to be horizontal. At this time, as shown in FIG. 7 (b), the spring members 449 and 449 are elastically supported at two points (4491 and 4492) on the rear portions 4493 of the rails 440a and 440b, respectively. A more reliable horizontal posture can be obtained.

  Then, the rotary solenoid 420 is driven again, and the arm 421 rotates in the direction A in FIG. Then, as shown in FIG. 5C, the chuck 430 is opened. That is, the chucking by the chuck 430 is released by forming a gap between the tips of the upper and lower claws 431 and 432 of the chuck 430.

  Next, the data (corresponding to the predetermined cutting information) for obtaining the fraction of the tablet according to the prescription data by cutting the PTP tablet sheet 900 using the vertical and horizontal blades of the cutting unit 700. The ball screw 444a is obtained via the drive gear 442 and the driven gear 443 fixed to the drive shaft by driving the motor 441 of the lateral guides 440 and 400 according to this data obtained from the control device or the controller.
