Structural element in record-changing devices - allowing repeated playing, e.g. during singing lessons or language courses

摘要

Structural element for repeated operation, e.g. in record changing devices, which in an opt. n-fold pile of the changing device allows at least an (n-1)-fold repetition, comprises tensioning units with a borehole stacked over the record to be repeated on the stack-axis. These tensioning units slip one gear-step along each time during the gear changes, which occur at the end of the record. As they are without their own play-back area they allow the record to be repeated.
