摘要： A recording/reproducing apparatus is capable of operating with either one of two different types of tape cassettes which each have a cassette housing with a bottom wall having an underside formed with locating holes in a respective pattern, different from the pattern of the locating holes of the other type of tape cassettes. The recording/reproducing apparatus is provided with locating pin devices at least some of which have a retractable locating pin capable of retracting below a predetermined plane of the underside of the bottom wall of the positioned tape cassette when such tape cassette lacks a locating hole at the location of the respective locating pin device.

摘要： A reel lock mechanism for a tape cassette, including a lock portion having a pair of pawls adapted to engage a plurality of teeth formed at outer circumferences of a pair of tape reels for winding a tape, a slide portion slidably supported to a cassette case of the tape cassette, and a twistable connecting portion integrally connecting the lock portion with the slide portion. When one of the tape reels is moved in a slacking direction of the tape by vibration or the like applied to the tape cassette, the connecting portion is twisted by a moving force applied to one of the pawls to thereby rotate the lock portion. As a result, the other pawl is moved so as to rotate the other tape reel in a direction increasing a tension of the tape. Therefore, a locked condition of the other tape reel is prevented from being released, and the tape is always maintained under a proper tension, thus improving a reliability of reel locking.
