A splice detection apparatus which operates directly upon the solenoid which is conventionally used to bring the pinch roller into contact with the capstan of a recording/playback unit, eliminating the need for separate levering mechanisms, to detect changes in thickness between spliced and unspliced portions of a tape. Such differences are monitored directly at the solenoid, resulting movement of the plunger of the solenoid developing a change in voltage which is detected by appropriate electronic circuitry to develop a signal which indicates passage of the splice, and appropriately discontinues transport of the tape.
