Patent ID: 7379523

Claim:
An electromagnetic counter with built-in illumination comprising: a frame member; a cover member with a window for enclosing the frame member; an electromagnetic counting mechanism mounted on the frame member and including an electromagnet, an anchor that is rotated by magnetization and demagnetization of the electromagnet, and a plurality of number wheels at least one of which is configured to rotate through a predetermined angle in response to rotation of the anchor, said electromagnetic counting mechanism mounted on the frame member being disposed in the cover member so that each of the number wheels is exposed to the window provided in the cover member to form a display section and a count displayed by each number wheel is visible through the window; a light emitting diode for illuminating the display section and a wiring pattern for supplying electric power to the light emitting diode; a mounting board on which the light emitting diode is mounted, and on which the wiring pattern is formed, said mounting board being arranged in a space between the frame member and the cover member so that the light emitting diode is positioned in the vicinity of the number wheels; and a reflective surface to render the numbered wheels readily readable when illuminated by the light emitting diode, the reflective surface being provided on at least one of an internal surface of the cover member and configured with respect to the window of the cover member to reflect light from the light emitting diode toward the numbered wheels, a periphery of at least one of the numbered wheels, and indicia formed in the numbered wheels.
