<p>PURPOSE:To actuate both a tape driving system and a reel disk control system with accurate timing by setting both systems so as to make the states correspond to the made of a recording/reproducing device. CONSTITUTION:Plural independent cam grooves 30-32 are formed to a rotary disk which actuates a tape loadong mechanism with revolutions. Each of these cam grooves actuates exclusively a tape driving system or a reel disk control system. Then both systems are set so as to make the states correspond to the mode a recording/reproducing device. The grooves 31-32 turn clockwise in a body while the tape loading mechanism is active. While these grooves turns at the positions shown by 2-dot chain lines in a record/reproduction mode.</p> |
