ABSTRACT:
A tape playing machine which has a novel head deck which is capable of moving back and forth and which is mounted on three rollers so as to obtain smooth parallel back and forth action and wherein one of the normal actuating switches of record-players is eliminated and only five actuating buttons are required. The invention further encompasses plastic molded spring rear cassette mounting members which include a cassette biasing feature as well as a feeler pawl for engaging an opening in the cassette so as to determine whether the tape in the cassette can be erased. Additionally, the reel supporting hubs include a cylindrical member with interlocking fingers engageable with the reels so as to lock the reels to the tape chassis.
