And then pull it out. The base end portion of the mounting portion Ab extracted from the tip end portion of the cylinder Ac is dropped from the drop hole 3b and put into the chip accumulation container 19 (see FIG. 3). Note that the cylinder Ac and the mounting portion Ab from which the unburned injection needle Aa has been removed are made of synthetic resin and can be reused.

  The distal end portion of the mounting portion Ab where the needle dust generated at the time of burning and the unburned injection needle Aa remains is put into the needle dust collecting container 17, and the proximal end portion of the mounting portion Ab from which the unburned injection needle Aa is removed Is inserted into the chip accumulation container 19, so that the tip of the mounting portion Ab where the needle dust generated during burning and the unburned injection needle Aa remains, and the base of the mounting portion Ab where the unburned injection needle Aa is removed. It can be collected separately at the end.

  Further, the chip accumulating container 19 is taken out from the take-out port 2b of the apparatus main body 2, and the base end portion of the mounting portion Ab from which the unburned injection needle Aa has been removed is collected, so that the cylinder Ac and the mounting portion made of synthetic resin are collected. Ab can be reused.

  When the syringe A from which the mounting portion Ab has been pulled out is pulled upward and the tip end of the cylinder Ac is pulled out from the insertion hole 4a of the receiving plate 4, the receiving plate 4 is pulled out by the restoring force accumulated in the coil spring 7. Since the c moves back from c to the processing position a, the used injection needle Aa to be subsequently processed can be burned out.

  The air containing the odor generated when the injection needle Aa burns and the burnt odor generated when the mounting portion Ab is cut is filled with activated carbon of the deodorizing body 22 by the ventilation force of the fan 20a of the ventilation device 20. The air deodorized by the deodorizing body 22 is exhausted from the opening 2c toward the outside of the device body 2 to prevent the smell from being burned out to the surroundings. can do.
