摘要： Improved electromagnetic counter of either addition or deduction type of which digit wheels can be reset at zero or any preset nemeral value by depressing a resetting button is provided. The resetting button is normally locked in non-operative state but the lock is released as required by inserting a separate enabling key for actuating resetting mechanism associated with the button. The button lock means is detachable so that the button may be of either normally non-operative or freely operative type as desired. In the case of deduction type and a presetting mechanism including presetting buttons is provided, the presetting buttons are normally locked in non-operative state and the lock is released to be operative simmultaneously with the actuation of the resetting mechanism. The presetting and counting mechanisms are provided with respective improved means for maintaining accurate counting and presetting of digit wheels in association with the lockable resetting mechanism.
