An audio/control head for used in a Video Cassette Recorder or the like has a core holder arranged to include positioning portions and for determining the pitch length P and pressing tabs having an elasticity for pressing inwardly cores members and against the positioning portions and from the outer side. As the cores members and are held directly on the positioning portions and , they are inwardly pressed by the pressing tabs . Then, the core pitch p is precisely determined between the audio core and the control core without using a particular jig during the assembly. The overall number of jigs required for mounting the cores to the core holder can be reduced. Also, the core pitch P can be improved in the accuracy and the characteristics of the head will be consistent.

Audio/control head and method of assembling cores of the head

In a mounting structure for mounting a conductive shielding case, accommadating therein an audio magnetic head, to a chassis via of an adjusting plate, columnar protrusions formed on both side surfaces of the shielding case are engaged with groove portions formed on cut and raised pieces of the adjusting plate. With this arrangement, it is possible to fix the shielding case and the adjusting plate. Thus it is possible to fix the shielding case to the adjusting plate without using screws, and thereby be decrease the cost of parts and manufacture.

Structure for mounting a magnetic head to a chassis

A pinch roller device is provided wherein an elastic cylindrical roller is fitted over a cylindrical holder in the inner wall of which are formed a small hole and a large hole b 1 wherein a bearing is fitted in the large hole and a bearing stopper sleeve is pressed into the large hole so that the bearing can be rotatably fitted over a roller shaft.
