Claims

[Scope of utility model registration request]

(1) In an automatic rhythm performance device that stores a normal rhythm pattern and a fill-in rhythm pattern, and performs automatic rhythm performance while switching and selecting one of the rhythm patterns, the on-timing and off-timing of the fill-in rhythm pattern are used. an input means for inputting the on-timing and the off-timing, and when the input means inputs the on-timing and the off-timing, the clock data of the time-measuring means and the on-timing data or the off-timing data at the time of input are stored as paired data, respectively. an automatic rhythm performance device comprising: a storage means for performing the automatic rhythm performance; and a control means for sequentially reading out the paired data from the storage means to execute the automatic rhythm performance. 1

(2) The automatic rhythm performance device according to claim 1, wherein the time measurement data is data indicating the elapsed time from the start of the automatic rhythm performance.

(3) The time measurement data is data indicating the elapsed time from the on-timing to the off-timing, or it, and the elapsed time from the off-timing to the on-timing. The automatic rhythm performance device according to scope 1.
