However, as a result of experiments in which the shutter 18 was actually opened and closed several thousand to tens of thousands of times, the inventor of the present invention found that the following problem occurred in the manner in which the spring member 25 was applied. That is, the spring support shaft 22 integrally protruding from the bottom wall 4 of the main body case 1 made of plastic is made of the same plastic as the case material;
5 is made of metal. The spring member 25 is formed by forming a clearance between its cylindrical coil portion 25a and the circumferential surface of the spring support shaft 22 in order to exhibit a spring action. The circumferential surface of the spring support shaft 22 is subjected to a torsional moment and is scraped by strong sliding contact.
At this time, powder is generated. Furthermore, the edge of the arm portion 25b that is engaged within the groove 22a of the spring support shaft 22 scrapes the inner surface of the groove 22a, generating powder. The shavings generated in this way invade the tape accommodation area A where the hub 3 exists or the tape running area B and adhere to the tape 2, and especially the tape 2 in the tape running area B beside the spring support shaft 22. It tends to adhere directly to the surface, causing dropouts.

According to the present invention as described above, the spring member 2
5 and the spring support shaft 22 are prevented from adhering to the tape 2 as much as possible due to the presence of the wall 26, and therefore drop-outs caused by adhesion of the chips are prevented as much as possible. We have succeeded in reducing this as much as possible. In particular, the spring support shaft 22 is located on the side of one end in the left-right direction of the pocket rear wall 10a, which makes the opening of the pocket 10 smaller than in a case where the spring support shaft 22 is disposed in front of the pocket rear wall 10a. The area is secured as large as possible. Therefore,
When the deck is loaded, the tape loading member on the deck side can be smoothly inserted into the pocket 10 from below. In this way, the back wall of the pocket 1
The spring support shaft 22 is located on the side of the pocket 0a, but since the wall 26 is arcuate, a part of the circumference of the wall 26 is overhanging into the tape storage area A behind the pocket rear wall 10a. tape 2 in tape running area B.
Even if the tape 2 is loosened, the tape 2 will not be damaged because it will come into contact with the circumferential side of the wall 26. Of course, the wall 26 wraps around so that the other end 26b in the circumferential direction faces the pocket 10, and the tape 2
This also prevents the tape from touching the cylindrical coil portion 25a of the spring member 25, which is also effective in preventing damage to the tape.
