Indicating recorder

摘要

An indicating recorder comprising a housing unit, an internal frame unit and an electric power source unit. The housing unit includes a single-swing front door and is made from a square prismatic housing formed by bending a thin plate. The internal frame unit is positioned in the vicinity of the inlet of the housing unit and is rotatable in a direction opposite the front door so as to be drawn out toward the front. The internal frame unit has left and right side plates and coupling beams between the two side plates, and principally comprises an indicating recorder mechanism having a chart feed mechanism, a recording pen mechanism, and other related instruments. The electric power source unit is located in the housing unit and is equipped with a power transformer and a terminal board unit, both of which are in a rear frame region to provide power supply and input signals. The wiring for the terminal board and the power transformer is run along a transverse frame and connected to the internal frame unit by a flexible zigzag wire holder.
