ABSTRACT:
The record changing cycle of an automatic record changer having an umbrella type centering spindle is modified so that a delay is provided at the appropriate point in the cycle when the bottom record is to be released from the record stack. This delay is sufficient that a thin, lightweight bottom record has time to become unstuck from the remainder of the stack and fall downwardly before the record changing cycle is resumed, thereby preventing malfunctioning of the record changer when changing thin, lightweight records.
