Mechanical Counter Dial Diagram - How Analog Digit Wheels Work #176749 (License: Personal Use)

This diagram illustrates a classic mechanical counter mechanism with three rotating digit wheels labeled for thousands (left), hundreds (center), and tens (right). Each dial features numerals 0-9 arranged clockwise, with pointers indicating current values-here showing 3,000 + 600 + 30 = 3,630. The small vertical indicators at corners suggest gear engagement or reset mechanisms.
