PURPOSE:To reduce considerably the man-hours for production of a connection cord to make the whole of a recorder inexpensive by arranging a stabilizing member, which stabilizes generation of a laser light, in a laser power source. CONSTITUTION:A stabilizing resistance 13 is arranged in a laser power source 12 as the stabilizing member which stabilizes the generation of the laser light. The laser power source 12 and a laser tube 1 are connected to a connection cord 14, and a connection cord 14a of this cord 14 connects an anode terminal 15 of the tuber 1 and the stabilizing resistance 13 in the power source 12, and the other connection cord 14b connects a cathode terminal 16 and the power source 12. Since the stabilizing resistance 13 which is embedded in the connec tion code 14 in conventional constitution is arranged in the power source 12 in this constitution, the man-hour for production of the cord 14 is reduced consid erably, and the whole of the recorder is made inexpensive.
