[0051]
(4) Operation of the subsequent compression packaging device 1 in the next cycle (see FIG. 11)
Thereafter, as shown in FIG. 11 (i), the workpiece D is compressed by raising and lowering the compression plate 5 in the compression chamber 4. Here, since the lock mechanism 30 and the eject hook mechanism 50 are in the initial state, even if the compression plate 5 is moved up and down in the compression chamber 4, the locked state (blacked) is maintained. Since the string R is not detached from the cable and the non-operating state is maintained, the tilted bottom plate 41 is not operated.
[0052]
