<p>@ The upwardly extending reproducing stylus (100) is shielded within opening (24) in phonograph (16) when recorded-message carrier (12) is not in playing position by a cover member (246). A cam (256) unshields stylus (100) and exposes it in an arcuate slot (244) when a pin (274) on recorded-message carrier (12) exerts a downward force on cam (256) during the coupling of carrier (12) to opening (24) by engaging annular grooves (290) with detents (44, 46, 48).</p> |
