- a plurality of guide ribs 74 extending in the sliding direction of the shutter 38 are juxtaposed in the left-right direction of the shutter to guide the sliding of the shutter 38 (see FIG. 13).
- the shutter 38 is inserted into a gap between the carrier 37 and the shutter guide member 71 so as to be slidable in the front-rear direction from an insertion port 82 (see FIGS. 15A to 15C) on the rear end side of the carrier 37.
- the shutter guide member 71 guides the bottom surface and the left and right side edges.
- the left and right guide sides 77 are guided by the guide rollers of the shutter guide member 71.
- the shutter 38 When the shutter 38 is inserted deepest, it overlaps the entire bottom surface of the carrier 37 and closes the bottom surfaces of all the compartments 67 (see FIG. 15A). At this time, the shutter 38 does not adhere to the bottom surface of the carrier 37 and prevents the passage of the tablet 29, but there is a gap ⁇ having a size that allows passage of the dust 83 such as chipping of the tablet 29 that is small below a certain level. Is set as follows.
- the dust discharge slit 79 coincides with the upper surface of the slit 80 of the shutter guide member 71.
- the bottom surface of the compartment 67 of the carrier 37 on the front side and the square hole 69 of the shutter guide member 71 are sequentially opened, and the tablet 29 in the compartment 67 is placed in the tray. 24 is discharged.
- the brush 68 comes into contact with the upper surface of the shutter 38, and the dust 83 that has passed through the gap ⁇ of the partition wall 66 of the carrier 37 is captured by the brush 68.
- the front side end of the shutter 38 matches the slit 80 of the shutter guide member 71 and is discharged to the dust receiving tray 64 installed below the shutter.
- the dust 83 on the upper surface of the shutter 38 is captured by the brush 68 (see FIG. 15C), and the slit 79 of the shutter 38 becomes the shutter guide member.

- the protruding member 81 passes through the partition chamber 67 as shown in FIG. 11B, so that the partition wall 66 facing the partition chamber 67 is clogged in a so-called bridge state.
- the projecting member 81 comes into contact with the tablet 29, and the posture of the tablet in the compartment 67 is lost, the clogging is eliminated, and the tablet is reliably dropped into each storage recess 26 of the tray 24.
- tablet bridges are likely to occur when the distance from the opposing partition wall 67 is shorter, and the bridges are formed so as to cross the sliding direction. For this reason, when the protruding member 81 moves across the generated bridge, the posture is easily broken.
- the projecting member 81 is configured so that the hypotenuse 81a is positioned on the front side when the shutter 38 is opened, and the tablet 29 in the bridge posture is lifted from the lower side as it moves, so that the posture is easily broken. At the same time, the tablet is less likely to be sandwiched between the partition wall 66 of the partition chamber 67 on the downstream side in the moving direction.
- the buffer unit 36 is connected to a driving device 39 via a gate-shaped bracket 70 (see FIG. 9A) connected to a carrier 37, and is integrated with a shutter 38 and a shutter guide member 71. Then, it is driven by the drive device 39 and controlled to execute one cycle of the transporting process per tray 24 in the horizontal plane of the packaging unit 14.
- one cycle of the transporting process is based on the position where the buffer unit 36 is present above the standby position b of the mounting table 30.
- the buffer unit 36 is a position for discharging the tablets 29 to the tray 24 on the mounting table 30, and this position is referred to as a discharge position A.
- One cycle of the buffer unit 36 passes through the receiving start position B where the receiving of the tablet 29 is started from the discharge position A of the original position below the dispensing port 21 of the tablet 29 and the receiving end position C where the receiving of the tablet 29 is completed in order.
- a step of returning to the original discharge position A is executed.
- all the compartments 67 of the carrier 37 are in a state that matches the arrangement of all the storage recesses 26 of the tray 24 on the mounting table 30 at the standby position b.
- the interior of the compartment 67 is empty and the shutter 38 is in a closed state.
- the following receiving process is executed from the receiving start position B to the receiving end position C in the middle of the transporting process. That is, at the reception start position B, the carrier 37 is positioned such that the (1, 1) compartment 67 (see FIG. 8B) is below the dispensing port 21.
- each compartment 67 is moved below the dispensing port 21 one by one in accordance with the timing when the tablet 29 required for one dose is dispensed from the dispensing port 21 to receive the tablets. Receipt starts from the compartment 67 of (1, 1), and as shown by the arrow in FIG. 8 (b), it proceeds (1, 2,) (1, 3). (2 doses) are received, and the following (2, 1) (2, 2)... The position of the carrier 37 when the final position (7, 4) is reached is the reception end position C. Returning from the receiving end position C to the discharging position A, the one-cycle conveying step is completed.
