PURPOSE:To cut off the undesired load within an adaptor and to improve the operability when a tape is driven, by connecting an intermediate rotary member to a take-up reel via a revolving mechanism and having non-connection between the intermediate rotary member and a rotary member in the modes excepting a rewind mode. CONSTITUTION:The operating force of an operation knob 8 of a miniature tape cassette adaptor 1 is transmitted to take-up reels 25 and 26 of a miniature tape cassette 23. Thus transmission gears 9-13 set a tape 27 back to a position within a cassette from a position inside the adaptor 1. Then the engagement with an intermediate gear 12 is released when other gears connected to the gear 12 connected to a driving reel shaft of a recording/reproducing device. As a result, the gears outside a transmission line formed between the gear 12 and the driving reel shaft have no revolution when the tape 27 is driven by driving the driving reel shaft at a video recording/reproducing speed. Thus no driving load is produced for the driving reel shaft. |
