のである。"Operation" Therefore, when the foot pedal 13 is stepped on, the opening/closing lid 3 opens and the upper end opening 2' opens, so the used injection needle 18 and syringe 19 can be placed on the injection stand 17 through the opening 2'.
When the petal 13 is raised by raising the hind foot inserted into the V-shaped downwardly inclined gutter 2, the opening/closing lid 3 is closed. Due to this closing operation, the cam 20 turns on the limit switch 21, and in response to the signal, the drive motor 16 is rotated multiple times, the drive device 15 is rotated multiple times, and the elevating and lowering rotating arm 8 is raised and lowered multiple times. The injection needle 18 and syringe 19 whose lower ends are stopped by the stopper 5 and are directed into the receiver 10 and the inclined gutter 2 are cut by the shearing blade 7 provided on the rotating arm 8 and the fixed blade 6. The cut pieces are then dropped and discharged from the gap as the holder 10 is lowered. With the lowering of the shearing blade 7 of the receiver 10, the spring 1
2, and as it rises, it rises to its original position (solid line position in Figure 2) by the force of the spring 12, and the shear blade 7
has risen to the solid line position in Figure 2, so the syringe 19
The shearing blade 7 slides under the blade 7 to the stopper 5, and in this state, the shearing blade 7 moves up and down in the same manner as described above to shred the syringe 19 several times, cutting the needle 18 and the syringe 19 into small pieces. It is discharged as

The horizontal axis 22
It is supported by A cam 20 is attached to this horizontal shaft 22.
is provided, and the cam 20 turns on the limit switch 21 during the closing operation, thereby transmitting a closing operation signal. A foot pedal 13 is provided at the bottom of the machine box 1, and the pedal 13 and the operating arm 4 of the opening/closing lid 3 provided on the horizontal shaft 22 are connected by a Bowden wire 14.
The lid 3 can be opened by stepping on the petal 13 (by lowering it), and the lid 3 can be closed by removing the foot from the petal 13 (by raising it) and applying force such as a spring (not shown). ing. In the direction of the lower end of the downwardly inclined gutter 2, a syringe 1 is inserted through a small piece discharge port s.
9 and a lowering stopper 5 for the injection needle 18, a V-shaped gutter-shaped fixed blade 6 along the V-shaped end face of the gutter 2 is provided between them, and a shearing blade 7 perpendicular to the fixed blade 6.
is provided on the vertically rotating arm 8, the base of the arm 8 is pivotally supported to the base frame 9 by a pin 23, a sliding arm 24 is provided on the base, and a long hole 25 is bored in the sliding arm 24. The pin 27 provided on the rotating disk 26 is inserted into the elongated hole 2.
5 to form a drive device 15 which can make the arms 8 and 24 reciprocate once for each rotation of the disc 26. The disk 26 is provided on the output shaft of the deceleration drive motor 16, and the motor 16 is controlled by the signal to automatically stop after rotating a plurality of times. Further, the space between the fixed blade 6 and the stopper 5 is closed by a cut-part receiver 10, thereby preventing the separating injection needle 18 from falling downward.
