In this way, the needle tip discarded to the duct chute 139 from the opening 1302b of the storage box 130b is recovered by the needle recovery box 362. At this time, the sensor 3612 provided in the latch case detects the protrusion 3625 erected on the needle collection box 362.

  In the staple processing apparatus of this embodiment, as described above, when the needle collection box 362 is taken out from the needle collection unit 36, the insertion port 362a of the needle collection box 362 is always closed by the sliding lid 3622. Therefore, scattering of the collected needle tip when the needle collection box 362 is removed from the needle disposal position can be prevented.

  FIG. 8 is a diagram showing another aspect of the present embodiment. In the members shown in FIG. 8, the same members as those shown in FIGS. 6 and 7 are given the same reference numerals as those shown in FIGS. 6 and 7.

  FIG. 8 (a) shows a needle collection box 362 in this embodiment corresponding to FIG. 6 (a). In this aspect, the sliding lid 3622 slides along the main body 3621 in a direction in which the needle collection box 362 is fitted into the latch case 361. The latch case 361 is provided with a box stopper 3612 that restricts the movement of the needle collection box 362.

  Further, in the needle collection box 362 shown in FIG. 8A, lid stoppers 3627 and 3628 for restricting the movement of the sliding lid 3622 are erected on the main body 3621.

  The sliding lid 3622 is provided with a spring latch 36221 that engages with a convex portion 3613 provided in a guide concave 361a of the latch case 361, which will be described later.
