A counter, as a key part of the odometer mechanism, was invented by an Ancient Greek mathematician and engineer Hero of Alexandria who lived in 10 - 70 AD
The counter was improved and completed with a reducer that reduced the number of the wheel’s revolutions depending on the measuring system (miles, leagues, kilometres) and showed reduced data on the display
Counters are used to count the number of passengers, visitors of different events, cars passing through certain check point, sets and scores in sport, items on a production line, etc.
Assembly requires no glue or additional tools. The details come out of the boards with a slight push
