Abstract

PURPOSE:To make the assembling process of the titled device easy by forming a rotary member fixing rotors for a pair of cylindrical rotary transformers on its inner diameter surface and fixing rotors for plane-opposed type rotary transformers on its one end surface. CONSTITUTION:The plane-opposed type rotary transformer rotors 21 and the cylindrical rotary transformer rotors 7 are adhered to the end surface inner diameter surface of the member 19 respectively and one end of the member 19 is fixed on a rotary drum 2 with screws 20. Since all the opposed surfaces of the plane-opposed type rotary transformer rotors 21 are used for signal transmission, many signals can be transmitted. Although the plane-opposed type rotary transformer stators 22 is coupled with a fixing drum 11 by screws 23, the stators 22 may be fixed with adhesives instead of the screws and the adhered fixing may expand the opposed area.

[Background of the Invention] A conventional example is shown in FIG. 1, which relates to a mounting structure. Conventionally, in order to replace the magnetic helads 1a and 1b, the rotating transformer rotor 6 is attached to the rotating drum 2 with screws 10, and has a removable structure, but because of the mounting screws 10, the opposing area of the rotating transformer is Due to this limitation, it was not possible to add rotating transformers to transmit multiple signals.

An example will be explained with reference to FIGS. 2 and 6. In FIG. 2, the planar rotating transformer rotor 21 is glued to one end surface of the member 19, and the cylindrical rotating transformer 7 is glued to the radial surface of the member 19, and one end of the member 19 is attached with a screw 20. is fixed to the rotating drum 2 by.

Since all 0-pointers can be used for signal transmission, it is possible to transmit multiple signals. In Fig. 2, the flat-faced rotating)-7th stator 22 is fastened to the fixed drum 11 with screws 23, but it is also possible to fix it with adhesive to further expand the facing area. . FIG. 6 shows a partial assembly diagram of the member 19 in which the planar rotating transformer rotor 21 and the cylindrical rotating transformer rotor 7 are bonded and integrated. [Effects of the Invention] According to the present invention, Since the facing area of the planar facing rotary transformer can be expanded, it is ideal for multi-functional rotary magnetic head drums equipped with multiple heads, and
Since the two rotary transformers are integrated into one, the assembly process is simplified and the process can be shortened. Also, since the surface of the rotating drum has a mirror-like finish, it is easily scratched, but by shortening the punch, the occurrence of defects is reduced. Rukoto can.
