Abstract: A time meter comprises a money receiving mechanism for receiving a denomination of money. The money receiving mechanism includes a movable output member which moves by an amount determined by the denomination of money received. The time meter further comprises a money signal generating device for generating a money signal. The money signal generating device cooperates with the money receiving mechanism and produces a money signal which is responsive to movement of the output member. The time meter further comprises a processing device for processing the money signal. The process device has a time signal generating device for generating a periodic time reference signal. The processing device measures time during a time interval having a duration determined by the money signal. The processing device provides a time expiry indication when the time interval has expired.
