Abstract
The wireless device includes: a frequency setting unit which sets a frequency; a first frequency display unit which displays the set frequency as a set-up frequency in numbers; and a second frequency display unit which draws at least one predetermined frequency range, centering the set-up frequency, on a scale having a fan shape by interlocking the at least one predetermined frequency range with the setting of the frequency performed by the frequency setting unit. Here, the scale is rotated about a virtual center point having the fan shape of the scale, and a center of the scale is shown to always correspond to the set-up frequency.
Claims8
A wireless device comprising:
- a frequency setting unit which sets a frequency;
- a first frequency display unit which displays the set frequency as a set-up frequency in numbers;
- and
- a second frequency display unit which shows at least one predetermined frequency range in a graphical form, centering the set-up frequency, on a scale having a fan shape by interlocking the at least one predetermined frequency range with the setting of the frequency performed by the frequency setting unit,
- wherein the second frequency display unit shows scale marks in a graphical form at regular intervals corresponding to predetermined frequency intervals on the scale, and shows numbers of a part of a frequency corresponding to the predetermined frequency range in a graphical form by deleting digits from an upper digit to a first predetermined digit and deleting digits from a lower digit to a second predetermined digit, in the vicinity of a corresponding marking, and such that a virtual center point of the scale having the fan shape is below characters of the numbers.
A method of displaying a frequency, the method comprising:
- displaying a set-up frequency set by a frequency setting unit which sets a frequency, in numbers;
- displaying at least one predetermined frequency range, centering the set-up frequency, on a scale having a fan shape interlocked to the frequency setting performed by the frequency setting unit;
- showing scale marks in a graphical form at regular intervals corresponding to predetermined frequency intervals, on the scale;
- and
- showing numbers of a part of a frequency corresponding to the predetermined frequency range in a graphical form by deleting digits from an upper digit to a first predetermined digit and deleting digits from a lower digit to a second predetermined digit, in the vicinity of a corresponding marking, and such that a virtual center point of the scale having the fan shape is below characters of the numbers.
