<p>PURPOSE:To shorten a search time by permitting a control micro computer to judge whether the absolute time of the number of a music which is search- requested is known or not by means of a search request and executing search by the absolute time if it is known and executing search by a start ID if it is not known. CONSTITUTION:A corresponding relation between the whole music numbers and the absolute time is stored in a RAM13c. A processor 13a in the control micro computer 13 checks whether there is the search request in the middle of play, or not. When the search request occurs, the processor 13a discriminates whether the absolute time of the number of the objective music which is set in a ten key 14b is known or not with collating a table corresponding to the music numbers and absolute time stored in the RAM13c. If it is not known, a search processing by the start ID is executed, and if it is known, the search processing by the absolute time is executed, whereby play is executed after search. Thus, the search time can totally be shortened.</p> |
