摘要： An electromagnetic pulse counting mechanism comprises a rectangular block shaped housing having first and second housing parts which are interengageable and with one part defining a side wall and a rear wall and the other part defining all of the other walls. The other part includes an intermediate partition wall between the top and bottom walls, which has a coil receiving tube extending rearwardly thereof. An electromagnetic coil is positioned over the receiving tube and a U-shaped magnetic yoke has one leg portion inserted into the tube and another arranged alongside the coil in the housing. The opposed side walls of the housing define journals for receiving shafts of a cypher roll or rolls and an indexing mechanism for indexing the cypher roll or rolls. An armature is supported in this end of the housing directly adjacent the coil and one leg of the yoke and it is moved by actuation of the coil to move the indexing mechanism to advance the cypher roll. The front wall of the one part of the housing includes a window opening for viewing the cyphers on the rolls which are exposed in the window.
