ABSTRACT:
A magnetic tape strip for the reproduction of bell sounds is set to play one or more of a multiple number of different melodies or programs wherein the programs are arranged on tape segments in parallel groups with each group separated from each adjacent group by an appropriate divider or "window". Half of the groups of programs are recorded or encoded on one end of the tape and play during tape travel in one direction and the other half recorded or encoded at the other end of the tape and play during travel in the opposite direction.
Mechanism acts to physically stop tape travel after completion of each program and when two or more programs are to be played, rewind the tape in the direction opposite the direction of travel needed to play the next selected program. In the event an end of play sensor fails to stop tape travel at the end of a program, an optical sensor will stop tape travel.
The arrangement and location of the programs on the tape is such that by a simple adjustment the same mechanism used for play can also be used to record or encode on any one or more program spaces.
