Filed: 1981-02-16
Abstract: PURPOSE:To get rid of influence by a brake in case when a reel table device is executing a rotary operation for winding a tape, by providing a one-way clutch between a reel table wheel and a brake wheel. CONSTITUTION:In a supply reel table device A, a reel clutch spring 308 is installed to the outside circumferential surface of an inside circumferential shaft 307b of a brake wheel 307, and the outside circumferential surface of an axial part 306b a reel table wheel 306, and it is wound round in the tightening direction when a reel table 301 is rotated clockwise. Accodingly, when the reel table wheel 306 or a reel gear 305 has been rotated and driven clockwise, that is to say, for intance, in case of the reproducing mode, its rotation is transferred to the brake wheel 307, and a brake effect of a band brake 280 is obtained. When the reel table 301 has been rotated counterclockwise, however, that is to say, in case of the back turn mode and the reproducing mode in the reverse direction, the clutch spring transfers no force to the brake wheel 307, and the brake band 280 exerts no influence on the reel table 301.

Abstract: PURPOSE:To minimize capacity of power supply by providing a current transformer detecting AC current of a main circuit and a rectifier converting an output of the current transformer into a DC, and supplying the output of the transformer to a negative gate current power supply of a self turn off type thyristor. CONSTITUTION:When an electrostatic induction thyristor (SITY) 1 starts an opening and closing operation, a negative gate current is supplied to the SITY 1 from a power supply 3 in every extinction of arc, so that the current having a some value is outputted. While, as an electric current of a main circuit is supplied to an AC line CC, the current is also supplied to a secondary line of a current transformer 4, and it is converted into DC by a rectifier 5 to input to the power supply 3. The input current is decided by a current ratio of the current of the AC line CC and the current transformer 4, and a stable operation is possible because of depending on no voltage of the power supply 3. Accordingly, the power supply 3 may have a current capacity of the difference between the current to be outputted to the SITY 1 and the current to be inputted from the current transformer 4. According to this constitution, the capacity of the power supply 3 can be minimized by setting a current ration of the current transformer 4 properly.
