Abstract
For switching over from playback of the owner's announcement text to recording a message from a caller, a pause of defined length is present on the announcement tape between the first and second (or end) parts thereof. This pause is recorded and on every run of the announcement tape through the apparatus the reading, recorded for the length, undergoes comparison with the pause of the announcement tape being transported. When the two values are the same, switch over takes place. In this way, it is possible to make certain of switch over without being dependent on the tape speed, and the circuit system may be made very much less complex.
