ーを移動することが出来。Conventionally, the tape was stretched along the opening provided on the front side of the tape to prevent dust from adhering to it and contact with foreign objects such as fingers, and to prevent deterioration of tape performance. In some cases, not only a front lid covers the front surface of the tape, but also an opening into which a post for pulling out the tape from the casing is inserted, is closed with a slide cover, or a member is provided to cover the inner surface of the tape. However, in the case of a structure in which the opening is closed by a slide cover, the tape cassette becomes thicker by the thickness of the slide cover, and the structure becomes complicated in order to smoothly move the slide cover. Additionally, the slide cover can be moved extremely easily with your fingers.

題点を有している。3 I gave it a rating of 7 because it is an issue where contact with the beige tape is easily possible. - For tape cassettes where the opening into which the tape drawer post is inserted is relatively small, the entire flexible body such as Mylar film comes into contact with the inside of the tape stretched on the front, and there is a risk of contact with foreign matter that enters through the opening. There are structures that protect against However, if the area of the tape stretched over the opening is large, permanent deformation will occur due to changes in temperature and humidity during long-term storage of the flexible body, making it difficult to completely cover the tape from the inside. It is. A structure in which a flexible body is integrated and rotated continuously in the longitudinal direction of the tape as a member that covers the tape from the inside of the casing is also considered, but the rotation range of the rigid body is limited and the opening It has problems such as not being able to take up a large area.

がテープカセットの上面部の一部を形成し、他端部は。The following configuration can be considered to solve these problem sounds to some extent. In other words, as a means of protecting the tape stretched on the front of the casing from the inside, the tape stretched at a position facing the front cover is covered from the inside through the stretched tape, and the tape is covered with a different rotation than the front cover. It has a moving fulcrum and covers the stretched tape from the inside, and at least within the stretching range of the tape facing the opening, one end in the rotating direction of No. 7 covers a part of the top surface of the tape cassette. Form the other end.
前蓋とともにテープ全実質的に包囲する位置において、
前蓋の一端と当接あるいは近接する裏蓋全段けたもので
あり、第１図及び第２図において簡単に説明する。In a position substantially surrounding the entire tape with the front lid,
This is a full-length back cover that abuts or is close to one end of the front cover, and will be briefly explained in FIGS. 1 and 2.

, which is very advantageous in terms of protection. Furthermore, in the state shown in FIG. 2, the chevron 103i is completely opened, which is convenient for loading, etc. Of course, the respective fulcrums are selected so that the front cover 104 and the back cover 106 do not come into contact with the tape 103 even during the transition wJ process from the vane in FIG. 16 to FIG. 2.

巾。In this way, this configuration is extremely simple even for tape cassettes that cover a large area within the opening of the stretching tape, and is particularly effective against contact with fingers, dust, etc. from inside the opening.
Although the tape 103 is designed to completely prevent deterioration of tape performance due to the accumulation of dust, depending on the precision of each part, dust and dirt may accumulate at the stretched position of the tape 103 even in the state shown in Figure 1. It may invade. For example, the lower side of the tape 103 is the protrusion 104a of the front lid 104.
and the protrusion 106a of the back cover 106 come into contact with each other, and the difference between the two is the width of the cassette.

Particularly if it is a molded part made of resin, it is possible that it may warp slightly during use, and accuracy cannot be expected to be very high, so in the end, a gap will form at this contact point.
Dirt and dust are a common threat to every human being.

。Figure 8 L/f... shows a state in which the front cover 3 and the back cover 4 are in a position where their rotation is fully restricted by force, and this is a state in which the front cover 3 and the back cover 4 are closed. In this state, when the cover is opened, the tip of the arm 36 is inserted into the 1° cutout 37 of the front cover 3 and is located below the tape cassette 1 in the thickness direction. Cassette garage (not shown)
By pushing down the tape cassette 1 in the direction of the main body of the device after insertion, the lid opening means 38 opens the cut length @ 37 of the front lid 3 and the lid of the back lid 4 relatively from below in the thickness direction of the tape cassette 1. It enters from the direction of arrow 39 at a position corresponding to the arm 36, and the tip of the arm 36 is pushed up when the lid is opened. When the lid is opened, the manufactured lid 4 begins to rotate in the direction of the arrow 4o as the arm 36 moves, and when the lid is opened, the notch 37 of the front lid 3 is completely formed within the automatic range of the tip of the arm 36. The front lid 3 is also rotated 410,000 times by the arm 36 to open the lid. As the lid opening means 38 advances, the opening 37 of the front lid 3 is removed from the rotation range of the tip of the arm 36. M'i] The lid 3 and the manufactured lid 4 have portions with different relative heights so that the lid 3 and the lid 4 can each be independently rotated to the optimum position 1. (See Fig. 9.) The closing operation of the front cover 3 and the manufacturing cover 4 is performed using a cassette garage (not shown).
When the lid opening means 3 moves backward 11 pages due to the rise of By pulling out the retape cassette 1 from 25, the locking member 20 engages with the engagement protrusion 24 of the front cover 3, and regulates the rotation of the front cover 3.At the same time, the back cover 4 is also opened using the arm 36.

る。As is clear from the above explanation, the tape cassette according to the present invention has a tape cassette stretched from the outside of the casing.
With the cover and the stretched tape covered from the inside-@
The tape forms a part of the upper surface of the tape cassette, and the other end touches or is close to one end of the front cover, and the stretched tape is used to protect against contact layers such as beckons and dust. C. It is protected from the adhesion of foreign matter such as dust, and since each part is made to meet M at the bottom of the tape, the N degree of each part is relatively low, and if warping etc. occurs. Although it has a very simple structure, it completely protects the tape in order to prevent the intrusion of dust and dirt.
