Abstract

PURPOSE: To improve detection stability and reliability separating the movable part of a counter from a read device by providing magnetic-substance pieces corresponding to display numbers on a number wheel and then by varying magnetic force between a Hall element and magnet by them.
CONSTITUTION: As number wheel 11 turns, magnetic-substance pieces 14a, 14b... provided corresponding to positions of display numbers rotates and magnetic- substance piece 14a corresponding to display number 12a, for example, is interposed between permanent magnet 15 and Hall element 16 to magnetize magnetic-substance piece 14a by magnet 15, providing a magnetic field to Hall element 16. Then, a constant current, supplied to element 16 from a constant-current supply, operates upon the magnetic field provided to the Hall element to develop a Hall voltage corresponding to magnetic-field intensity in a direction perpendicular to the current, so that this voltage will be detected through amplifier 18. As a result, a number displayed can automatically be read out.
