The size, shape and material of the diffusion plate provided in each nozzle are arbitrary. For example, in the above embodiment, the case where the nozzles 60 and 70 having the diffusion plate are held in the nozzle holder 10 has been described. However, the present invention is not limited to this configuration. A nozzle holder that holds the provided nozzle may be used.

For example, as shown in FIGS. 13 (a) and 13 (b), in a mounting apparatus for mounting N types of nozzles having a rectangular diffusion plate, each of the locking claws 21a, 21b, 2
2 may be arranged at a distance L from the edge of the diffusion plate, and may be configured to slide in opposite directions. In this case, nozzles having different sizes can be attached and detached with a small slide amount L. The slide amount L is not limited to １ ／ of the length of one side of the minimum diffusion plate.

21b and 22 are arranged at a distance L from the end of the diffusion plate in the sliding direction, and the locking claws 21a and
A notch 220 may be formed at the tip of each of 21b and 22 so as to slide in the opposite direction. In this case, nozzles having different sizes can be attached and detached with the slide amount L or less.

The configuration for sliding the resetters 20a and 20b in the opposite directions is not limited to the configuration using the link mechanism, but is arbitrary. For example, resetter 20
A rack may be provided at each of the racks a and 20b, a gear that meshes with both racks may be arranged, and the slide of the resetter 20a may be transmitted to the resetter 20b via the gear.

The notch 220 formed in the locking claw 22
It is not limited to the configuration formed on one side surface of the locking claw 22, but is formed according to the shape of the nozzle or the sliding amount of the resetter,
For example, it may be formed on both side surfaces.

The mounting pitch of the nozzle and the sliding amount of the resetter can be arbitrarily changed according to the shape and size of the nozzle, the width and length of the locking claw, and the size and shape of the notch at the tip.
