In a coin-freed apparatus for the phonographic recording of postal cards (as described by a swarfless indentation process) a store contains different types of cards and the user is able to select the type of card that he wishes to record, the selected card being transported from the store to the recording turntable where it is recorded and played back and then ejected into a slot accessible to the user. As shown, A carriage 11, Fig. 3, carries stacks 10 1 , 10 2 , 10 3 of cards in separate compartments of which the bottoms are automatically adjusted under the control of feelers (19, Fig. 4, not shown) so that the top card is always at the same level. Alamp L1, L2, or L3 warns of the depletion of a corresponding stack. By depressing a selected button K1, K2 or K3, the user causes the carriage 11 to be driven along guides 25, operating microswitches (T1, T2, T3, Fig. 4) in sequence, and to be stopped with the selected stack of cards located beneath two suction pads 41 which then pick up the top card 10 from the stack and transfer it, through movement of a belt 57 running on pulleys 55 and 56, to the recording device which includes a recording arm 102 and a playback arm 103. The overall sequence of operations is controlled by a camshaft (83, Fig. 5, not shown) actuating microswitches (N 0 to N 10 , Fig. 11, not shown), and a second cam-shaft (145, Fig. 7, not shown) is now set in motion to control the recording and playback of the selected card 10. A cam M1, Fig. 9, raises firstly a spindle 116, which passes through the hole in the centre of the card 10 and lifts a lever 157 carrying a roller 155, and secondly the turntable 101 to engage the card 10. When recording and playback have been completed, using a telephone handset J, Fig. 3, the turntable 101 and spindle 116 are lowered and the recorded card 10 is ejected by rollers 150 and 155. The user may declutch the turntable 101 to interrupt the recording by pressing button K, Fig. 3. The record material is preferably polyvinyl chloride and is locally softened by the recording stylus, which is of diamond (either polished or rough) and is heated by friction with the record material. The record blanks may be either plane or stamped with an unmodulated groove.
