Abstract

A timing apparatus comprising a time plate equipped with light transmitting holes or brushes which are positioned, at points representative of times and arranged at equal intervals in at least one row. The light transmitting holes or brushes serve as logical connection elements indicating such times. At least two rotators are coaxially disposed inside the time plate in a rotatable manner and also have light transmitting holes or brushes respectively corresponding with the logical connection elements on the time plate. The relative speeds of rotation of the time plate and the rotators are predetermined in such a manner so that the position of each logical connection element on the time plate and the positions of the corresponding logical connection elements on the rotators come into alignment at a given time indicated by the elements, thereby effecting electrical or optical timing connection at a desired time.

Dependent claims

An apparatus comprising one or more timing devices, each timing device including a rotatable time plate having thereon time-representing points where time-indicating logical connection elements are to be provided, said points being arranged at least in one row at equal intervals in the direction of rotation;

each timing device further including at least two rotators capable of rotating at different speeds in the vicinity of said time plate and individually holding at least one time-regulating logical connection element:
wherein at least one of said time plate and said rotators of each said timing devices is used in common when a plurality of said timing devices are provided and wherein the time-representing point and the time-regulating logical connection element in each of said timing devices are in such positional relation that the time-regulating logical connection element comes into alignment with the time-representing point only at a given time assigned thereto;
and the time-indicating logical connection element provided at said point and the time-regulating logical connection element of each rotator in each of said timing devices cooperate to effect timing connection through a logical product obtained at the given time assigned to said point;
and either the time plate or the slowest rotator is installed to be stationary.
