发明名称 SECTION REPEATING CIRCUIT FOR HELICAL SCAN SYSTEM TAPE REPRODUCING DEVICE
摘要 <p>PURPOSE:To execute a section repeat inspective of time information by detecting the correspondence of the variable quantity of a frame address and the variable quantity of a frame address calculated from the counted, contents and running a tape in a reproducing state. CONSTITUTION:A microcomputer 26 latches a frame address read from the reproduction start part of a section repeat. Thereafter, a tape reproduction is continued until a reproduction end position for executing the section repeat is set, and in this time, a microcomputer 26 detects the value of a frame address read from each track, and counts the number of times by which its value is varied to '0' from '15'. Subsequently, when the reproduction end position is set, a frame address read from the reproduction end part of the section repeat is latched. By discriminating a tape position by reading the frame address, and determining a reproducing start position and a quick return reproduction start position, a section repeat function can be realized even if time information is not recorded.</p>
