Abstract
For the measurement of the diameter of coins (1) or other circular objects, such coins or other objects pass the guide channel at substantially the same velocity. In a lateral wall of the guide channel, at least two photoelectric detectors (3, 4) are arranged at different heights which are obscured by such coins or other circular objects when passing the channel (FIG. 1 ).
Claims11
A device for the measurement of the diameter of circular objects comprising an oblique guide channel along which such object passes at substantially the same velocity at least along a part thereof,
- characterized in that
- in a lateral wall of the guide channel, two photoelectric detectors are arranged at different heights on a line which is perpendicular to a flat floor of the guide channel, said photoelectric detectors obscured upon passage past the same of such circular object,
- a further photoelectric detector is arranged at a distance from one of said two photoelectric detectors at the same height as said one photoelectric detector, and
- a first one of said photoelectric detectors which is obscured is adapted to start two timers, a first timer which is halted by obscuring of a second one of said photoelectric detectors and a second timer which is halted by obscuring of a third one of said photoelectric detectors.

- characterized in that
- in a lateral wall of the guide channel, at least two photoelectric detectors are arranged at different heights on a line which is perpendicular to a flat floor of the guide channel, said photoelectric detectors obscured upon passage past the same of such circular object, and
- an additional photoelectric detector is arranged, in the direction of motion of the object, in front of an upper one of said two photoelectric detectors and at a distance therefrom greater than the largest diameter of the objects to be measured.
