Abstract

PURPOSE:To freely control very small change to improve operativity by controlling an object to be controlled by means of proportional or logarithmic control signals with respect to a shift amount of an input device. CONSTITUTION:An encoder device 1 converts a rotation shift amount by a control dial 2 into a shift amount input pulse signal (a) and outputs to a proportional conversion circuit 4 or a logarithmic conversion circuit 5. The proportional conversion circuit 4 outputs a control signal (b) which is proportional to the shift amount indicated by the signal (a), while the logarithmic conversion circuit 5 outputs a control signal (c) which is proportional to a logarithmic value of the signal (a). Either signal (b) or (c) is selected by a changeover switch 8 by means of a changeover switch 7 on a control panel 6, and an object 3 to be controlled is controlled by the selected output (d). Thus very small change can be freely controlled by switching over to the circuit 4 in a part where a control amount which the circuit 5 cannot easily shift by a small amount is large.

いている。[Prior Art] In video equipment, measuring instruments, etc., in order to control a large amount of control over a small and variable range, the amount of movement is used as a control input, converted to an electrical signal by an encoder device, etc., and then converted into a control signal. A movement amount input control device for conversion is used.

Conversion into a control amount can be roughly divided into linear proportional conversion as shown in FIG. 2 and logarithmic conversion as shown in FIG. 3.

う問題があった。However, even in this case, in a section where the controlled amount is large, the change in the controlled amount is very large with respect to the change in the input movement amount. Therefore, linear control is more appropriate when it is desired to make a minute change in a section where the control amount is large, whereas logarithmic conversion has the problem of making it difficult to match the target control amount.
