29761号公報にて公知である。(b) Conventional technology Conventionally, in a cassette tape recorder,
An arc-shaped contact is provided on the lid of the cassette insertion slot,
It was invented in 1983 that the cassette bulging step part could be easily inserted into and ejected from the cassette, and the cassette could be inserted and ejected smoothly.
It is known from the publication No. 29761.

装に際して不都合な面があつた。 However, in order to form an arc-shaped contact on the lid, it is necessary to create an arc that protrudes from the plane of the lid. It has the disadvantage that it is easily deformed by stress when moving to the insertion position and is weak in strength. Also, since the arcuate part is formed on the side that contacts the top surface of the cassette, it hits the switch board for the operation switch at the front of the tape recorder's escutcheon, and if you want to avoid this, you will have to change the shape of the escutcheon. However, there were some inconveniences during implementation.

A contact element is provided that makes point contact with the inner apex angle of the side edge of the cassette bulging step when the cassette is discharged.

形状に制約を与えない。(e) Function According to the lid of the cassette insertion port in the cassette type tape recorder of the present invention, the contact makes point contact with the inner apex angle of the side edge of the cassette bulging step, so that it is difficult to insert the cassette. During ejection, the contact between the lid body and the contact piece is rotated smoothly without any deformation force, and since the contact piece is bent in the opposite direction to the cassette insertion slot, the shape of the escutcheon is maintained. No restrictions.

り大になるよう設定している。(F) Embodiment FIG. 1 is a diagram showing the structure of the lid of the cassette insertion port in a cassette tape recorder according to an embodiment of the present invention, in which 1 indicates the side having an inner apex angle 2 and an outer apex angle 3. The cassette is a well-known cassette having a bulging step 5 with an edge 4. 6 is rotatably supported by a shaft 9 provided in the cassette insertion opening 8 of the escutcheon 7 so as to be freely openable and closable, and is always urged in the direction of the cassette insertion opening by a spring 10. This is a lid for a cassette insertion port in a cassette type tape recorder that moves in a right angle direction and sets at a recording/playback position below the cassette insertion port 8. Reference numeral 11 designates a portion of the rotatable free end of the lid 6 of the cassette insertion opening in a direction opposite to the flat side 6' that contacts the cassette 1, so that the cassette bulges when the cassette 1 is inserted and ejected. This is a contact provided so as to make point contact with the inner vertex 2 of the side edge 4 of the stepped portion 5. The contactor 11 is provided at a part of the rotatable free end of the lid 6 at an inclination angle θ ₂ greater than an inclination angle θ ₁ of the side edge 4 of the cassette bulging step 5 with respect to the longitudinal direction of the cassette, and , the inner end 11' of the contactor 11 is configured to be located inward of the cassette 1 from the inner apex angle 2. Furthermore, contact 1
The bending angle θ ₃ of the cassette 1 is larger than the inclination angle θ ₄ between the side edge 4 of the cassette 1 and the bottom surface 12 when the cassette 1 contacts the top surface 1' of the cassette 1 within the cassette insertion plane. It is set so that

触し、円滑に蓋体６を回動するものである。 As described above, the cover of the cassette insertion port of the cassette type tape recorder of the present invention is constructed so that when the cassette 1 is inserted into the cassette insertion port 8, the cassette bulge 5 is in the open position as shown in FIG.
The inner apex angle 2 of the contact 11 comes into point contact with the spring 10.
The cover 6 is rotated against the force of the contact 11. Then, at the cassette recording/playback position shown in FIG. 1b, the cover 6 comes into contact with the top surface 1' of the cassette 1 so that the cassette 1 can be seen from the outside. When the cassette 1 is ejected, the top surface 1' of the cassette 1 comes into contact with the contact 11 when the cassette 1 is moved upward from the lower recording/playback position.
Since the cover 6 and the contact 11 are in point contact with each other,
The cover 6 is attached to the cover 6 without causing a strong deformation force at the contact portion with the cover 6.
The lid 6 then abuts against the upper surface 1' of the cassette 1 and is rotated, and when the cassette bulging portion 5 reaches a position where it abuts against the contact 11, the inner apex angle 2 comes into point contact with the contact 11 as shown in Figure 2, allowing the lid 6 to rotate smoothly.

２は接触子１１に当接するものである。 In inserting and ejecting the cassette as described above, since the inner end 11' of the contact 11 is located inside the inner apex angle 2, it is ensured that the inner apex angle 2 hits the contact 11. It is something that comes into contact with people.

ため好ましくない。 Although it is conceivable to configure the contactor 11 to make point contact with the outer apex angle 3, this is not preferable because the guide member (not shown) of the cassette 1 is adjacent to the outer apex angle 3.

A contact element is provided on the side opposite to the flat side of the cassette by bending to make point contact with the inner vertex of the side edge of the cassette bulging step when inserting and ejecting the cassette. In the
The contact between the lid and the contact can be rotated smoothly without any deformation force, and the bending direction of the contact is different from the flat side that contacts the cassette, which is opposite to the cassette insertion slot. Since it is provided on the opposite side, there is no restriction on the shape of the escutcheon.
