Abstract: A moving magnet type indicating instrument comprising a moving magnet type instrument, a counter mechanism, a drive unit, and a frame body produced of a synthetic resin. The magnet type indicating instrument includes a magnet mounted in bobbins produced of the synthetic resin, a needle shaft fixed to the magnet, and a coil wound at an angle on the bobbins. The bobbins are housed in a magnetic shield case and the coil is electrically connected to terminals provided on the bobbins. The counter mechanism, including a total counter and reset counter having a zero-resetting device, is mounted on the frame body. The drive unit comprises a case including a step motor for driving the counter mechanism and a groove of gears, and is fixed to the frame body. Terminals for the moving magnet type indicating instrument and the drive unit are inserted and connected to the connectors provided on a printed-circuit board. Therefore, it is possible to easily electrically connect and fix the moving magnet type indicating instrument and the drive unit to the connectors on the printed-circuit board through these terminals.
