Abstract:
PURPOSE: To simply ensure the connection when an orchestral accompaniment music is updated by sending music data in terms of an optical wave or an electromagnetic wave.
CONSTITUTION: When a new music loader 2 down-loads a new music to an orchestral accompaniment equipment 1, the new music loader 2 is set to a position specified by a guide 28 of the orchestral accompaniment equipment 1 and a power switch 62 is closed. When an enable switch 10 of the orchestral accompaniment equipment 1 is closed, a control section of the orchestral accompaniment equipment 1 and a control section of the new music loader 2 are hand-shaken via light receiving and light emitting element sections 20, 42 to down-load a new music automatically. A down-load indicator 30 is lighted during down-loading. After the indicator 30 goes off, the power switch 62 of the new music loader 2 is turned off and the loader 2 is removed from the upper part of the orchestral accompaniment equipment 1 by having a grip 31 in hand and then the down-loading is made complete.
