Abstract

PURPOSE:To reduce the store space of a cassette tape and to attain a compact and thin design of a tape recorder when no cassette tape is loaded, by using a cover having a turning fulcrum which can move in the thickness direction of the cassette tape to form the tape recorder main body and its turning fulcrum. CONSTITUTION:A cassette cover 9 is attached turnably to a link 13 via a turning fulcrum 15, and the link 13 is attached onto a tape recorder main body 8 via a turning fulcrum 14. At the 2nd position where a cassette tape is loaded, the link 13 is turned counterclockwise centering on the fulcrum 14 and then stopped at a position where an end part 13b of the link 13 touches the main body 8 to be set at the 2nd position. When the cassette tape is loaded and unloaded, the cover 9 is turned clockwise centering on the fulcrum 15 on the link 13. In this case, the amount of turning is decided by the position where a stopper 13a on the link 13 has a contact with a rib 9a of the cover 9. Then the tape cassette can be loaded and unloaded.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tape recorder with improved cassette tape attachment/detachment structure and cassette lid storage structure.

Conventional configurations and their problems Tape recorders, which are desired to be more portable, have become smaller due to the miniaturization of electrical circuit components and improvements in mechanisms.
Nowadays, there are tapes that are as small as the size of a cassette tape case. In this case, the size of the tape recorder was limited by the battery 1, flywheel 2, and cassette tape 3 itself.

Figure 1 (7) and (a) show the appearance of the tape recorder in that case.
Figure 2 shows the state when the cassette is attached and detached.

This tape recorder device has a built-in radio receiving circuit, etc.
Even if you want to enjoy radio reception and there is no need to install the cassette tape 3, the external dimensions shown in Figure 1 are required, and the cassette tape storage space will only become an empty space.
There was a problem in that the external dimensions could not be reduced.

In order to solve the above problem, as shown in FIG. 3, the rlJ of the main body 4 is set to 1, and the main body cover 6, which slides on the main body 4 by the distance axis, is rotated about the rotation fulcrum 6a. A device has been devised in which the cassette lid 6 is configured, and when the cassette tape 3 is not attached, the main body cover 6 is moved by a distance L2, and the width of the tape recorder is reduced by Q3. Here, the appearance when the case cover 6 is retracted is shown in the fourth figure.
As shown in the figure.

However, with this 4114 configuration, it is difficult to make the reduced dimension a2 larger than 24, and it is not possible to provide a sufficient sliding guide length, making it difficult to move the case cover 6 smoothly and making it unstable. However, the cost was also high.

1 The middle dimension of the main body 4 is Ql, which is smaller than the middle dimension 2 of the main body when it is not telescopic, and the arrangement of electrical circuit parts, mechanism parts, etc.

The problem was that there was no space to incorporate radio receiving circuits, recording circuits, etc.

Purpose of the Invention The zero-shot 8A solves the above-mentioned conventional problems.When a cassette tape is not installed, the cassette tape storage space is reduced, the tape recorder is made smaller and R-shaped, and the electric circuit components are reduced. Another object of the present invention is to smoothly and easily attach and detach a cassette tape and expand and contract a tape recorder without reducing the space for arranging mechanical parts.

Structure of the cassette tape The present invention is composed of a cassette lid having a main body and a rotation fulcrum that is movable in the thickness direction of the cassette tape. 1 position, a cassette tape is installed and cassette t4 is closed, a second position allows various operations such as circle: raw, fast forward, etc., and a 3rd position allows the cassette tape to be attached and removed, and the cassette tape is attached. The volume of the tape recorder is configured to increase or decrease when the cassette tape is not installed, making the tape recorder even more compact and compact when no cassette tape is installed.
It is configured in a zI type.

DESCRIPTION OF THE EMBODIMENTS FIG. 5 shows a tape recorder according to an embodiment of Kibori J, showing a plan view and a side view with the cassette lid 9 closed (first position).

In Figure 6, 8I'i main body, 9 cassette lid, 1o
11 is a playback button, 11 is a stop button, 12 is a fast forward knob, 13 is a link, and 14 is its rotational fulcrum, and the side view is shown with a cassette tape loaded and the cassette lid 9 closed (second position). It shows.

FIG. 7 shows a side view of the cassette tape in a removable state (third position).

FIG. 8 is a side sectional view of FIG. 6, in which the mechanism board is 16, the flywheel is 17, the pinch roller is 18, and the cassette lid 9 is rotatably attached to the link 13 via the rotation fulcrum 16. I'll get it installed. Note that the link 13 is attached to the main body 8 via a rotation fulcrum 14.

The operation of the tape recorder of this embodiment configured as described above will be explained below.

The second position where the cassette tape is inserted is as shown in FIG. 9, where the link 13 rotates counterclockwise around the rotation fulcrum 14 and is locked at a position where the end 13b of the link touches the main body. It will be in the second position.

Next, to insert and remove the cassette tape,
As shown in FIGS. 9 and 10, the cassette lid 9 is rotated clockwise about the rotation fulcrum 15 on the link 13. As shown in FIGS. In that case, the amount of rotation is the amount of rotation of the stopper 1 on the link 13.
3& and the rib 9a of the cassette lid 9 are in contact with each other, and the cassette can be attached and detached.

Next, a first embodiment of the present invention will be described.
This will be explained with reference to FIGS. 1 and 12. FIG. 11 corresponds to the second position, and FIG. 12 corresponds to the first position.

19 reel stands are rotatably housed on a reel stand board 12 attached to a support 22 planted on a mechanism board 16, and on a compression coil spring 20 inserted into a reel stand shaft (not shown). ing. The motor power switch 23 is housed on the mechanism board 16,
The contact piece 23a faces the second protrusion 9b of the cassette lid 9''.

Next, its operation will be explained. After the cassette tape has been removed, when the cassette M9 is pushed in, the back surface 9c of the cassette lid pushes the tip of the reel stand 19, compressing the spring 20 and moving it to the first position, as shown in FIG.
Reel stand” Nido! It is possible to make the device smaller and thinner than the configuration example in which the liI function is not applied.

In addition, since the switch 23 has a contact piece 23a pushed in by the protrusion 9b of the cassette lid 9, each operation knob (10 to 12
) is operated, the motor (not shown) does not rotate and the contact surface between the reel stand 19 and the back surface 9C of the cassette lid is not damaged.

Effects of the Invention According to the present invention, a tape recorder having a simple cassette lid and easy operation of the cassette lid makes it possible to reduce the volume of the tape recorder when no cassette tape is attached, and is excellent in portability and design. can be realized.

In addition, the only space that can be reduced in volume is the cassette storage space, which is wasted when no cassette tape is installed, and the space for placing mechanisms and electrical circuit parts is not reduced, so radio receiving circuits, etc. It has the excellent effect of being built-in and multi-functional.
