Abstract

PURPOSE:To mount recording and reproducing amplifiers, etc. on a rotary drum, by ensuring a simple supply of power to a circuit provided to the drum with addition of a coil at the revolving side. CONSTITUTION:A coil 6 conducts to drive a motor 8, and therefore a revolving shaft 2 is revolved. A supporting member 9, a drum 10, a core 15, a coil 25, etc. are rotated in a body and together with the shaft 2. A coil 24 cuts the magnetic flux of a magnet 26 with revolution of the coil 25, and therefore an AC current is generated to the coil 25. This AC current is applied to a circuit part 13 via a lead wire 23 and converted into a DC through a rectifying circuit. This DC current is supplied to the recording and reproducing amplifiers, etc. as a power supply.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an MLD generating device using a rotating head such as a VTR, and particularly to a platform for mounting a circuit on a drum on which a rotating head is installed, and a platform that is commonly used for this circuit. There is something about Witg.

I am thinking of using the Ramu ζ recording amplifier and the rudder rotation of the Tanju Anfu temple to make the axial blowing sound of the S/IN temple one heavy. In this case, the circuit housed in the drum must contain 14L. As a way to maintain 4 Momme (!), one AC power is supplied from the outside via a rotary transformer, and this father σIc is installed in the tram. However, a method using a rotary transformer is considered, such as a method of blocking 4 DC currents via a slip ring.

A coil 12 is mounted on the outside of the upper m1 leg (9a), and a magnet is fixed to the portion of the fixed drum flll that the coil faces. This coil (25) and magnet abr constitute a generator 11b.

The output from the coil U5.1 of this light 11- is connected to a lead 1181 and is applied to the fluorescent circuit of the recirculating section fLs+ through the lead 1181.・In order to insert the lead shaft (21, 2, 2), the support part hole (remoxibustion drum aυII) shall have one eyelet and one expanded rib hole.

Depending on the configuration of the lea, when the coil (6) is turned on and the motor 18 is driven, the rotating shaft (2) rotates. The supporting member (91, drum (1u1, core (151, ν) rotates as one unit with the 111 i2i. Therefore, the coils U and II cut through the wax of the magnet, which causes stiffness.

A graceful rotation leads to the Wd, which is equipped with something that fits in the whale's head.

Therefore, according to the present invention, the wax source can be easily supplied to the circuit provided in the drum by arranging the coil in the rotating shaft. Furthermore, since a magnet is provided on the fixed side, the magnetic field of this magnet is a static field to the outside of the drum, and no noise is generated outside. Therefore, compared to the method of using a rotary transformer to provide AC input, it is possible to enjoy a much better effect. In addition, since there is no mechanical structure, it is suitable for 1b production and is easy to implement. Therefore, it is necessary to install four recording amplifiers, raw amplifiers, etc. on the rotating drum, or T-iJ' NI=,
