Abstract
An electronic apparatus having a musical alarm function and a display, which produced a musical sound when an alarm time is reached while also concurrently performing score display of the musical notes of the produced musical sound on a printed five-line staff. The display produces a display of another function when the apparatus performs a function other than generation of the musical sounds.
Claims4
An electronic apparatus having a musical alarm function, a function other than said musical alarm function and a display, comprising:
- a source of reference clock signals;
- time counting means for counting said reference clock signals to form time data;
- means for generating alarm time data;
- time display means coupled to said time counting means for displaying said time data;
- alarm function circuit means coupled to said time counting means and to said alarm time data generating means, said alarm function circuit means including:
- alarm time detection means for determining whether said time data coincides with alarm time data;
- note code memory means for storing note codes for a melody;
- note code readout means coupled to said note code memory means for sequentially reading out said note codes from said note code memory means when said time data is determined to coincide with said alarm time;
- and
- melody generating means coupled to said note code readout means for generating a melody according to said readout note codes;
- a plurality of optical display elements provided on and between lines of the five-line musical staff;
- scale display control means coupled to said optical display elements for selectively driving said optical display elements to display the notes of said melody when said melody is generated by said melody generating means;
- and
- function display control means coupled to said optical display elements for selectively driving said optical display elements to produce a display of said function other than said musical alarm function which the apparatus performs when said melody is not generated.
