PROBLEM TO BE SOLVED: To provide an electric keyer device which significantly reduces complicated precise adjustment in tuning a transmission speed even with a knob of a small diameter, can also set a transmission speed that a user selects usually, and is easily available by immediately returning to that transmission speed.SOLUTION: Transmission speeds (Max value and Min value) at a maximum position and a minimum position of a variable resistor 8 matched to a skill/capability of a user and a transmission speed (My value) that the user selects usually are newly provided in a RAM 6, a nonvolatile memory 12 or a program memory 4, these speeds are set by menus based on programming, and a gap between the Max value and the Min value is defined as a variable range by the variable resistor 8, thereby smoothing a speed change relative to an angle change of the variable resistor 8.SELECTED DRAWING: Figure 1 |
