Description

[Detailed description of the invention] (Field of industrial application) The invention uses a so-called Phillips-type cassette,
This invention relates to a compact tape recorder that is thin when a cassette is not attached.

(Prior art and its problems) Various methods have been devised to reduce the size of small tape recorders. Focusing on the fact that it is not necessary to keep the size of the tape recorder the same when it is not installed, a part of the cassette tape recorder is configured to be expandable and retractable, and when the cassette is not installed, the space in the cassette mounting section is saved. Using this technology, they succeeded in reducing the size of the tape recorder to almost the same size as a cassette.

However, although the plane size has been reduced, no effective means for reducing the thickness of the cassette has yet been proposed.

In other words, as shown in Fig. 3, in the Phillips type cassette, the portions where the capstan insertion hole and the positioning hole are provided are protruded from the upper and lower surfaces, respectively, so that the height of the cassette mounting part of the tape recorder is reduced. This is because it is difficult to reduce the thickness of the tape recorder main body because the thickness must be designed to include the protruding parts on the top and bottom faces, not the flat part of the cassette where the reel base insertion hole is formed.

(Purpose of the invention) The present invention is aimed at alleviating the above-mentioned drawbacks, and is intended to reduce the thickness of the tape recorder when no cassette is attached, thereby reducing the thickness of the tape recorder.

(Summary of the invention) The present invention was made to achieve the above-mentioned object, and consists of a tape recorder with a first lid facing the flat part of the cassette, and a second lid facing the protruding part of the cassette. and a lid body, and when the cassette is attached and the lid body is closed, the first and second lid bodies are respectively in contact with the flat part and the protruding part according to the shape of the cassette. With,
When the cassette is not installed,
Both lids are flush with each other at the flat portion of the cassette, and the thickness can be reduced by the amount of projection of the projecting portion of the cassette.

(Example) Figures 1a, b, and c show a state in which the lid of the tape recorder of the present invention is open, a state in which the lid is closed without a cassette attached, and a state in which the lid is closed with a cassette attached. FIG. 2 is an exploded perspective view of the tape recorder of the present invention, and FIG. 3 is a perspective view of the cassette.

In each figure, 1 is a tape recorder main body, and 2 is a cassette mounting section. Inside the cassette mounting section 2, reel stands 3a, 3b, capstans 4a, 4b, etc. are arranged by known means.

On the other hand, a lid 5 is attached to the cassette mounting section 2 of the tape recorder main body ₁ so as to be openable and closable. (see Figure 3), and a second lid 7 that faces the protruding portion _C2 (see Figure 3) of the cassette C where the capstan insertion hole, etc. is formed. The shafts 8 and 8 respectively arranged on the tape recorder main body 1
It is arranged so that it can rotate freely.

The lid body 6 can be moved between the open state shown in FIG. 1a and the open state shown in FIG. The closed state shown in FIGS. 1b and 1c can be selectively taken. A decorative plate 6b forming a cassette see-through window 6c is attached to the upper surface of the cassette, and the lower surface shows the cassette C when closed. A cassette pressing spring 10 is attached to press the flat portion _C1 , and the cassette press spring 10 is attached to the side surface to maintain the closed state by engaging with a lock lever 11 which is movable left and right on the side of the tape recorder main body 1 when the cassette is closed. A lock pin 6b and an engagement pin 6e that engages with the second lid 7 are provided.

The second lid 7 has a decorative plate 7a attached to its upper surface, one end of which is rotatably attached to the same axis as the first lid 6, that is, a rotation shaft 8, and a side surface on the free end side. An elongated hole 7b is formed which constantly engages with the engagement pin 6d of the lid 6 of No. 1. Therefore, the second
The lid 7 rotates together with the first lid 6 and can rotate relative to the first lid 6 within the range of the elongated hole 7a. Further, the second lid 7 is connected to the first lid 6 by a spring 12, and is always biased clockwise with respect to the first lid 6, that is, in the direction in which it is closed. Furthermore, this spring 12 has
A spring whose elasticity is weaker than that of the reversing spring 9 is used.

The tape recorder of the present invention has the above structure, and its operation will be explained next.

In the open state of the lid body 5, the first lid body 6 is held in its open state by the reversing spring 9, and the second lid body 7 is held in the open state as shown in FIG. 1a. The cover body 6 is rotated clockwise by a spring 12, and the rotation position is maintained by the upper end of the elongated hole 7b being engaged with the engagement pin 6e.

In this state, the positional relationship between the elongated hole 7b and the engagement pin 6e is determined so that the upper surfaces of the first lid 6 and the second lid 7 are flush with each other.

Therefore, if the lid body 5 is closed in the above-mentioned state without installing the cassette, as shown in FIG. 1b,
Both the first lid body 6 and the second lid body 7 are connected to the cassette C.
The plane portion _C1 of the cassette C remains flat at the height, and in this state, the thickness of the entire tape recorder becomes thinner by the protruding amount d of the protruding portion _C2 of the cassette C (see Figure 3). Become.

On the other hand, when the lid 5 is closed with the cassette C installed in the cassette mounting section 2 in the state shown in FIG. The second cover ₇ covers the flat part C1 of the cassette C, and presses the cassette C into the cassette mounting section 2 with the cassette pressing spring 10 on the lower surface thereof, and the second lid 7 abuts the protruding part _C2 of the cassette C. The protruding portion _C2 moves upward by a protruding amount d relative to the lid 6 of the cassette C against the elasticity of the spring 12, and eventually the elasticity of the spring 12 presses the protruding portion _C2 of the cassette C.

The closed state of the lid 5 is maintained by locking the lock pin 6d on the side surface of the first lid 6 with the lock lever 11 on the tape recorder main body 1 side.

In other words, when cassette C is not installed,
Even when the lid 5 is closed, the first lid 6 and the second lid 7 are flush with each other at the height of the flat part of the cassette C, so that the tape recorder can be opened by the thickness d of the protruding part of the cassette C. The overall thickness can be reduced, and when a cassette is installed, the protruding part of the cassette C can be
The _second lid 7 moves upward relative to the first lid 6 by the amount that C2 protrudes, and the cassette C can be held within the cassette mounting section 2.

In addition, in the closed state of _the lid body ₅ shown in FIG.
Since the lid body 6 and the second lid body 7 press the tape into the cassette mounting section 2, the tape does not wobble like a conventional tape recorder that presses only on the flat surface. The running system can be stabilized.

(Effects of the Invention) As described above, according to the tape recorder of the present invention, the lid of the tape recorder is arranged such that the first lid faces the flat part of the cassette and the second lid faces the protruding part of the cassette. When the cassette is attached and the lid is closed, the first and second lids are configured to abut against the flat portion and the protruding portion, respectively, according to the shape of the cassette. When the lid is closed with no cassette installed, both lids are flush with the flat part of the cassette, so when the cassette is not installed, the protruding part of the cassette The tape recorder can be made thinner by the amount of protrusion.

Furthermore, when the cassette is installed, the flat and protruding parts of the cassette are pressed by the lid, which is more effective in preventing rattling of the cassette than the conventional mechanism that presses only the flat part. In particular, since the protruding portion is close to the position where the head is inserted, pressing this portion is effective in obtaining good head touch and tape running.
