The present invention relates to a door support device for a portable thin cassette tape recorder, and to simplify the number of parts to improve productivity and to further reduce the cassette tape recorder.

In general, the portable thin cassette tape recorder is to open the door to insert the cassette tape on the inner side of the door, and then to transport the tape while the door is closed, so that the door is closed by its own weight when the door is opened. Door support is installed to prevent.

7 to 9 show an embodiment of a conventional door support device, the bracket 13 is integrally formed on one side of the main base 12 fixed inside the main body 11. The brackets 14 are rotatably coupled to the levers 14 and 15 having the fastening holes 14a and 15a, and the spot springs 16 having the projections 16a on the outside of the lever 15 are spot welded. The end of the leaf spring 16 to be supported by the locking hole 15b, and the projection 16a can be selectively inserted into the fastening holes 14a and 15a. It is coupled to the fastening plate 18 fixed to the (17) to be rotatable.

Therefore, as shown in FIG. 8, in the state in which the door 17 is closed, the projection 16a of the leaf spring 16 is inserted in the fastening hole 15a of the c-shaped lever 15. As shown in FIG.

However, when the door 17 is opened in the direction of the arrow of FIG. 9 to insert a cassette tape (not shown) into the inner side of the door 17, that is, inside the main body 11, the levers 14 and 15 are opened. The rotation of each lever 14, 15 is rotated until the projection 16a of the leaf spring 16 is inserted into the fastening hole 14a formed in the lever 14 so that the door 17 is rotated. This prevents it from closing by its own weight.

In addition, the opening angle of the door 17 is connected to the inner surface of the c-shaped lever 15, such as the ninth degree, so that the door 17 is not opened anymore.

Then, when a tape is inserted into the inner surface of the door 17 and an external force is applied to the door 17 to close the door 17, the projection 16a of the leaf spring 16 is formed in the lever 14 by the fastening hole 14a. The door 17 is closed by the weight of the door 17 because it is separated from.

However, such a conventional apparatus has a drawback in that its structure is complicated, and the cassette tape recorder has a large volume, as well as a decrease in productivity due to an increase in work processes such as spot welding.

The present invention is to allow the door to support the door without using a separate leaf spring by forming a projection and a notch groove in the lever, respectively, in view of the drawbacks of the prior art, as shown in the accompanying drawings 1 to 6 When described in more detail as follows.

Bracket 3 formed with boss 3a and stopper 3b is formed on one side of the subbase 2 provided inside the main body 1, and the boss 3a formed in the bracket 3 is shown in FIG. As shown in FIG. 1, the lever 4 having the first cutout groove 4a and the second cutout groove 4b is adapted to be coupled to the protrusion 1a formed on the inner surface of the main body 1. It is rotatably coupled.

A long hole 6a is formed at one end of another lever 6 rotatably coupled to the lever 4 and the fastening pin 5, and a protrusion 6b is formed outside the long hole 6a. 6b is elastic, and as the door 7 is opened and closed, the projection 6b is selectively in the first notched groove 4a and the second notched groove 4b of the lever 4 like the fourth tile. It can be combined.

In addition, the other end of the lever 6 is rotatably coupled to the fastening plate 8 and the fastening pin 9 fixed to the door 7.

Referring to the effect of the present invention configured as described above are as follows.

5 is a diagram illustrating a state in which the door 7 of the cassette tape recorder in which the inventive device is installed is closed, and the tape (not shown) is not inserted into the main body 1.

In this state, the projection 7b formed in the lever 6 is inserted into the first notch groove 4a of the lever 4 so that the door 7 is inserted into the main body 1 in order to insert the tape in the sixth. When the lever 4 is opened in the direction of the arrow, each lever 4 and 6 rotates the fastening pins 5 and 9 and the boss 3a in the axial direction, so that the projection 6b of the lever 6 is the long hole 6a. Due to the elasticity is pushed outwards to be separated from the first notched groove (4a).

As the door 7 gradually opens, the levers 4 and 6 also continue to rotate so that the projections 6b formed on the levers 6 reach the second cutout grooves 4b, and the projections 6b are driven by elastic force. Since it is inserted into the second notch groove 4b while restoring to the original state, the door 7 is supported. At this time, the stopper 3b formed on the bracket 3 is caught by the lever 4 so that the door 7 is closed. It will limit the opening angle of).

Therefore, when the cassette is inserted into the inner side of the door 7 and the force is applied to the door 7 in the direction opposite to the arrow, the protrusion 6b is pushed outward and is separated from the second notch groove 4b, and the door is reversed as described above. (7) is closed and becomes the same as the fifth degree, so that the apparatus can be operated.

As described above, the device of the present invention supports the door 7 by a simple structure in which the projections 6b and the first and second notch grooves 4a and 6b are integrally formed on each lever 4 and 6. Since the structure is simple, productivity can be reduced by reducing the work process, and the cassette tape recorder can be made smaller and thinner.

Claims (1)

In the door support device in which the main body 1 and the door 7 are connected by levers 4 and 6, the first notch groove 4a and the second notch groove 4b are provided at one end of the one side lever 4. And a long hole 6a at one end of the other lever 6 and a protrusion 6b to open and close the door 7 so that the protrusions 6b are formed in the first and second cutout grooves 4a and 4b.
