is magnetic tape. A rotary magnetic head is usually used as the recording/playback head. A signal processing device is a part that processes various signals from an image receiving section or a magnetic head, and incorporates, for example, an inductance element or a transformer. Taking an inductance element as an example, the conventional inductance element is a wire wound around a ring-shaped magnetic core. used. Such a ring-shaped magnetic core is sometimes constructed by laminating annular thin plate iron cores in the axial direction, or by winding long strips in a spiral shape to form a ring shape, but usually F e A ring-shaped magnetic core is often made by integrally molding −S i- based ferrite material into a ring shape. Generally, a ring-shaped magnetic core has a large magnetic flux density near the inner circumference. Therefore, when an inductance element having such a ring-shaped magnetic core is used in a high-frequency power circuit, magnetic saturation tends to occur at the inner peripheral portion of the magnetic core. In recent years, video cassettes made of alloy tape or vapor-deposited tape have tended to be used especially in video television cameras.
It is necessary to pass a large current, but in such cases, with conventional ferrite magnetic cores, the current distortion is large and can cause problems with electrical circuits, so to prevent this, the magnetic core is relatively large in shape. was.

り、発熱したりすることはなくなる。 The present invention solves these problems by configuring the magnetic core of an inductance element or transformer with a composite magnetic core made of an amorphous magnetic alloy material and a ring-shaped ferrite material, thereby making the magnetic core itself smaller and making it easier to wind. To provide a video television camera device which has fewer wires and is smaller and lighter as a whole. For this purpose, the present invention provides a video television camera device in which a rotary magnetic head, a signal processing section such as an amplifier, and an image receiving section consisting of a lens and an image receiving element are housed in a portable case. An inductance element in which an amorphous magnetic alloy strip is tightly wound around the inner circumferential portion of the ring-shaped ferrite magnetic core and a common coil is wound around the ring-shaped ferrite magnetic core and the amorphous magnetic alloy strip in the processing section. It incorporates. Since the amorphous magnetic alloy material has a high saturation magnetic flux density, it prevents the inner circumference of the ring-shaped magnetic core of the inductance element from becoming magnetically oversaturated or generating heat.

板の間および巻回した帯板間を固着してもよい。 FIG. 2 is a perspective view of an inductance element 11 using an amorphous magnetic alloy strip. The magnetic core 12 of the inductance element 11 is entirely constructed by wrapping a thin strip of an amorphous magnetic alloy material several times tightly into an annular shape. The coil 13 of the inductance element 11 has a wire wound around the side of the magnetic core 12 in the axial direction, as shown in the figure. FIG. 3 shows an embodiment of an inductance element applied to the present invention. In this case, an amorphous magnetic alloy strip is tightly attached to the inner circumference of a ferrite magnetic core 14 formed in a hollow cylindrical shape. The magnetic core of the inductance element is constructed by wrapping the plate 15 a plurality of times. Since the thin amorphous magnetic alloy plate has spring properties, when a flat band plate is wound to a diameter smaller than the inner diameter of the ring-shaped ferrite magnetic core 14 and attached to the inner circumference of the magnetic core, the coil is formed. The strip plate 15 widens at the inner circumference of the magnetic core and is tightly attached to the inner circumferential surface of the magnetic core 14. Depending on the case, a suitable adhesive may be used to secure the inner peripheral surface of the magnetic core and the amorphous magnetic alloy strip and between the wound strips.

で構成したものすべてに適用される。 The video television camera device of the present invention incorporates an inductance element made of laminated thin plates of amorphous magnetic alloy material, so even when high frequency power is applied, no heat is generated in the inductance element.
Furthermore, since the magnetic core has high coercive force and high magnetic permeability, fewer windings are required, resulting in an overall compact and lightweight television camera device. The present invention is applicable to not only inductance elements but also transformers and other devices in which the magnetic core of each element of a signal processing section in a video television camera is made of an amorphous magnetic alloy material.
