An automatic repertory dialer for use with a standard impulse telephone dialing system. A series of ten pulses for each digit to be dialed is generated by the motion of a programming belt on which is also stored, in coded form, a pluralty of telephone numbers which may be dialed. The number of pulses from each series of 10 pulses which are delivered to the dialing circuit is determined by the position of a mark on the programming belt. For each telephone number to be programmed, there are eleven positions on the programming belt associated with each digit of the telephone Number. These positions correspond to the number of pulses to be transmitted for that digit, from zero to 10. A mark in the appropriate position will cause that number of pulses to be transmitted for that particular digit. The circuit which accomplishes the dialing function is responsive to marks on the programming belt and transmits signals from the time the belt is in a first position to the time it assumes a second position, said positions being established by marks on the belt.
