PURPOSE:To give different instructions to an operator, by providing a means for discriminating and checking whether recording is executed by dividing into 2 parts or not, and whether both of them are read exactly or not, as to a magnetic tape on a sheet music face. CONSTITUTION:Whether the first and the second data groups 7a, 7b of a magnetic tape, which are recorded in a sheet music face 7 is read exactly or not is checked by a reading and checking circuit 3. Also, whether only one of the data groups is read or both of them are read is detected by a data discriminating circuit 2. In accordance with outputs of these check and detection, in case when only one of the first and the second data groups is read, and in case when both of the first and the second data groups are read exactly, different instructions are controlled by a read and notice controlling circuit 4 and are executed to an operator by a lamp or an alarm sound. |
