Title:
SPECTRUM ANALYZER WITH DATA KNOB
Document Type and Number:
Japanese Patent JP3413272
Kind Code:
B2
Abstract:
PURPOSE: To improve operativity, in frequently operating key switches while looking at a screen, by eliminating the movement of line of sight and hands for key operation to the most.
CONSTITUTION: A data knob 21 is provided with a pushbotton switch 12, and a switch status storing part 12b wherein the number of times the switch was pushed (switch signal 12a) is stored and the status whether the switch is pressed or not is determined and then switch status signal 12c is outputted is provided. A pulse conversion part 14 wherein, receiving the rotary pulse signal from a rotary encoder 24, the switch status signal 12c from the pushbotton, and the signal of a function mode register 13, conversion pulse signal 15 obtained by converting the rotary pulse signal by N-times is outputted, and function conversion signal 16 wherein the pushbotton switch 12 is assigned to an elements set switch function means is outputted, is provided, so that the frequency which the line of sight moves from the screen for elements setting operation is decreased.
