Abstract

PURPOSE:To improve the branch output voltage load effect surely with a simple circuit constitution, by connecting the resistor having approximately equal value as the input resistance of the circuit connected on and after the variable resistor between one end of the variable resistor and the slider. CONSTITUTION:The main line L is branched after the input terminal IN and is connected to the recording terminal REC and the MAX terminal 1 of the variable resistor RV. The MIN terminal 3 of the resistor RV is grounded and the slider 2 is connected to the number of order circuit NC having the input resistance Rc, and the resistor R having about the same resistance value Rc is connected between the terminal 1 and the slider 2. With this constituion, the branch output voltage eREC is made equal for the connection of the slider 2 to the MAX terminal 1 and to the MIN terminal 3. Accordingly, the variation of the input resistance RIN due to the position of the slider 2 can not be restricted possibly, then the effect of the branch output voltage load can surely be improved.
