Each of the wall portions 80a, 80b, 80c, and 80d is formed with a wiring fixing slit as with the wall portion 28d.

FIG. 17 schematically shows the wiring around the head 1.
In the drawing, thick lines represent wiring, and the wiring connected to the vibration motor 62 and the ground sensor 30b on the right side is fixed by the walls 80a and 80b. By fixing at two places, a plurality of wirings can be gathered and drawn around the suction port 12 without being separated inside the head 1.

Wires connected to the left and right vibration motors 62 are fixed to the wall portions 80c and 80d. Since the vibration motor 62 vibrates, vibration is transmitted to the wiring, but the wiring is fixed to the wall portions 80c and 80d. Therefore, the wiring can be prevented from moving more than necessary, and disconnection can be prevented.

The present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the scope of the present invention.
