摘要： In a magnetic tape cartridge having a detection opening which can be opened or closed with a plug to prevent erroneous erasure of recorded signals on the tape, an indication opening through which the plug can be seen from the outside and a slot through which the plug is positioned as desired are both formed in a first wall of the cartridge housing, and the detection opening is formed in a second wall located differently from the first, in such a manner that the indication opening or slot is selectively closed by sliding of the plug from one position to the other or vice versa. The plug includes an elastic lock member in sliding contact with the inner surface of the first wall. The first wall has two grooves such that, when the plug is in either position, the lock member fits in the corresponding one of the two grooves. The plug is L-shaped along the inner surfaces of the first and second walls, and the lock member is disposed in a recess formed within the plug.

摘要： In a magnetic tape cassette comprising a cassette housing, a lid pivotally connected to the front of the housing to open and close its front opening, and a lock member fitted in one front side portion of the housing and engageable with and disengageable from the inner surface of the lid, a lock-member-biasing spring is accommodated within the thickness of the lock member, with a free end engaged with the housing. The lock member has means with which to press the both end portions of the spring in place. It has also a bulge formed on its side opposite to the recessed side and which is larger in diameter than a pivot by which the lock member is supported by the housing. The bulge is accommodated within a wall opening of the cassette housing.

摘要： A magnetic tape cartridge is provided with a pressing spring secured to a cartridge to press a spring-contact projection formed at the center of the upper part of a reel. The pressing spring includes a reel-contacting part formed at its inner part, a spring-functioning part holding the reel-contacting part and a base plate connected to a root portion of the spring-functioning part. The reel-contacting part presses the spring-contact projection of the reel downwardly so that a pressing force acts on the reel in its axial direction.
