An electric signal is applied and the rotary drive mechanism rotates the shaft around the axis, and a part of the circumferential end surface of the disk-type cleaning horn is immersed in the cleaning liquid in the cleaning tank. . Accordingly, the disk-type cleaning horn 1 emits ultrasonic vibrations from the circumferential end face 1c while rotating part of the circumferential end face 1c in the cleaning liquid. Erosion occurs in a portion immersed in the cleaning liquid and does not occur in a portion in the air.

The ultrasonic vibration generated in the vibrator is transmitted to the cone 3, and the central vibration shaft 1 a of the disk-type cleaning horn is screw-connected to the cone 3, so that the ultrasonic vibration is transmitted to the disk-type cleaning horn 1. The light is transmitted and radiated in the radial direction from the circumferential end face 1c. When the center column of the duralumin disk-type cleaning horn having the dimensions shown in FIG. 2 was excited at 19.8 KHz, the axial amplitude was 1 unit.

The disk-type cleaning horn 1 is configured so that a part of its circumferential end face 1c is immersed in a cleaning liquid 5 stretched in a cleaning tank 4, and the ultrasonic vibration in the liquid is as shown in FIG. The light is radiated in the direction indicated by the arrow group A and the arrow group B in the drawing (b), and is irradiated on the cleaning object 6 immersed in the cleaning liquid 5. Since the disk-type cleaning horn is rotating, the entire circumferential end face uniformly emits ultrasonic vibration radiation in the cleaning liquid 5, and erosion generation is averaged without being concentrated only at a specific location.

As described above, the ultrasonic cleaning apparatus of the present invention uses a disk-shaped horn as the cleaning horn, and oscillates the ultrasonic vibration while rotating a part of the circumferential end surface of the horn so as to be immersed in the cleaning liquid. Erosion is not concentrated only at a specific location on the circumferential end face, but is averaged over the entire circumferential end face. Compared to a case where the surface that emits ultrasonic vibrations by being immersed in the cleaning liquid like a horn is fixed, the degree of erosion due to erosion is reduced, resulting in a reduced cleaning effect and a longer horn replacement period. There is an advantage that it becomes. Further, since the circumferential end face can be seen from above, there are advantages that the progress of the erosion can be easily observed, and that the tape can be easily washed.
