原因となっていた。Unique example of (tiI) formation and its problems In recent years, so-called compact tape cassettes have been widely used as tape cassettes for iZ Qd rivers, but this K does not have a brake device for the hub, so it cannot be removed from the cassette case. If you leave it unattended after taking it out, the tape will sag due to vibration, etc. I! This caused various problems.

トでは実施し難いものである。If the tape sag is large, there is a risk that the tape will protrude from the opening and be bent or cut. Furthermore, when the machine is used for the next time, there are problems in that it takes a long time to start up to perform steady running, and that the rotation of the take-up reel stand is not in time to wind up the tape being driven, resulting in jamming phenomena. It had a point. In order to solve these problems, many proposals have been made to incorporate a brake into the hub or to apply braking force to the outer circumference of the hub, but the former is difficult to materialize as it is, and the latter is Although this has been done with video cassettes, etc., it requires a large space and is difficult to implement with so-called compact tape cassettes for audio use.

In FIG. 2, 7 is a hub, and 8 is an engagement pin with the hub drive l1II of the cassette recorder. Reference numeral 9 denotes a blocking piece, which integrally forms the detection section 10 and the spring capital 11. Reference numeral 16 denotes a solid chevron-shaped blocking portion provided on a part of the blocking piece 9, and as described later, the blocking portion 16 is a solid blocking portion of the hub.
6 The pillars are designed to face the inside. Reference numerals 12 and 13 denote annular holding plates, which are attached by press-fitting or adhesive, and hold the blocking pieces 9 from both sides of the hub 7. Reference numeral 14 denotes an insertion groove for the blocking piece 9, which is also connected to a guide section of the detection section 10.

は回転可能状態となる。Fig. 4 is a top view showing the whole bald rotating shaft part provided on the cassette half side, 18 is the hub rotating shaft, and its outer circumference VC is the tooth shape ia.
A is formed. Therefore, when the tape cassette is not attached, that is, when the reel shaft is not inserted into the bald hole 4, the blocking portion 16 protruding from the inner surface of the hub bearing portion 16 engages with the tooth profile 18 of the cassette half, causing the hub to rotate. to prevent Therefore, sagging of the tape due to rotation of the hub is prevented. This rotation-preventing force prevents the hub from rotating when a large force is applied to the hub.
(The shape of the iAq type 1B+L and the elastic force of the spring part 110 are installed. In other words, it is good to have a blocking force that can prevent the tape from sagging during vibration. When the tape cassette is installed, the detection part is pushed by the reel shaft. 10 steps forward, chevron-shaped blocking part 1
5 moves back and is no longer engaged with the tooth profile 188L, so the hub becomes rotatable.

うにしたものである。FIG. 6 is a side cross-sectional view (corresponding to the section 1 taken along line a-a in FIG. 3) showing the main part of another embodiment of the guide structure of the detection part 10, and shows the guide groove of the detection part 10 of the blocking piece 9. It is formed into an undercut so that it can be held and guided only by press-fitting from above for detection @10.
１９はアンダーカット的に形成した案内溝である。19 is a guide groove formed in an undercut manner.

２０は案内溝で下１１ｔｌｊが閉じ、上側で広いている
故、円環状保持板を上側のみ（１２のみ）一枚の構成と
することが＋ｉＪ能である。Since 20 is a guide groove which is closed at the lower part 11tlj and is wider at the upper side, it is possible to configure the annular retaining plate with only one sheet on the upper side (only 12).

ープカセットを実現できるものである。Effects of the Invention The present invention includes a chevron portion on the outer periphery of the hub rotating shaft provided on the cassette half side, and a blocking portion that protrudes from the inner surface of the hub bearing portion of the hub, engages with the +nJ mark chevron portion, and prevents rotation of the hub when engaged. and,
a 1-1 force which is attached to the hub and which always urges the blocking portion inward so as to protrude from the inner surface of the hub bearing portion;
It is formed integrally with the blocking part J, and is connected to the hub drive Ill.
This tape cassette is equipped with a detecting section for detecting whether the tape cassette is mated with the knob, and is configured to automatically release the rotation prevention of the knob when the tape cassette is installed in the device. By preventing the rotation of the hub at the time of the valve assembly, it is possible to prevent the tape from sagging caused by the rotation of the hub. Furthermore, this tape cassette is compatible with current conventional cassettes, and since the blocking part, detection part, spring part, etc. are integrally formed as a blocking piece, the number of parts is small and assembly workability is extremely high. This makes it possible to realize a tape cassette with the same characteristics.
