Description

[Detailed description of the invention] The invention relates to a cassette holder device.
More specifically, the cassette holder is movable between a first position where the cassette can be attached and removed from the outside of the main body and a second position where the cassette is attached to the cassette mounting section and is ready for playing or playing. This invention relates to a cassette holding device suitable for use in a cassette tape recorder or the like installed in a cassette tape recorder.

Many devices equipped with the above-mentioned cassette holder have been proposed in the past, but in general, in these devices, the cassette is loaded into the cassette holder and brought to the cassette loading section, and the cassette loading section is When a cassette is attached to a cassette, it is necessary to hold the cassette in place in order to prevent it from rattling or shifting in any state. Moreover, when the cassette is mounted on the cassette mounting section, the relative position of the cassette with respect to the magnetic head, capstan, pinch roller, etc. must be accurately maintained, and vibrations from the mechanism, etc. It must hold down the cassette with pressure force.

On the other hand, some conventional cassette holding devices have a strong spring or the like placed inside the cassette holder to hold the cassette in place. Since both the cassette hold down and the cassette hold down on the cassette mounting section are performed with the same elasticity from one spring, the cassette can be held down on the cassette mounting section, but when the cassette is installed in the holder. ,
The strong pressing force of the cassette holding spring becomes an obstacle.
This has serious drawbacks, such as the cassette not being able to be installed smoothly, and unnecessary force being applied to the holder and its guide mechanism, which may cause damage to the holder.

In addition, in order to prevent such accidents, we have installed springs with a weak pressure force on the cassette holder to hold the cassette when the cassette holder is moving, and to prevent the cassettes mounted on the cassette mounting section from wobbling or misaligning. It has also been proposed that the cassette is held down by separate members depending on its position, by providing a strong spring or the like on the main body side to press with a strong force to prevent the cassette from falling. Not only is the structure complicated, but it also has problems such as the need to synchronize both members.

In order to solve the above problems, the present invention aims to bring the cassette from a detachable first position to a second position where the cassette can be played, and from the second position to the first position. a cassette holder, a rotating member rotatably provided on the cassette holder to suppress a cassette mounted thereon from above, an actuating piece rotatably provided on the cassette holder, and the actuating piece. a spring member suspended between the cassette holder and the rotating member; and a first position that locks the rotation of the actuating piece against the spring member when the cassette holder is in the vicinity of the first position. and a second stopper that abuts the actuating piece and rotates it against the spring member as the cassette holder moves from the first position to the second position. It is characterized by:

Hereinafter, one embodiment of the cassette holding device of the present invention will be described in detail.

In each figure, reference numeral 1 denotes a tape recorder main body, and a cassette insertion opening 1b for inserting or removing a cassette is formed in the front face 1a of the main body. A holder 2 is provided for loading a cassette inserted through the insertion opening 1b into a cassette mounting section (not shown) in the main body 1, or for ejecting a cassette mounted in the cassette mounting section to the outside of the main body. It is provided. This holder 2 has guide pins 2a and 2b on its side surfaces connected to an L-shaped guide groove 3a formed in a side plate (not shown) provided in the main body 1, which is formed by horizontal parts 31a and 31b and vertical parts 32a and 32b. , 3b, the horizontal portion 31a,
31b to the right in the figure, and then guided by the vertical parts 32a and 32b to move downward to load the cassette in the cassette holder into the cassette mounting section. ing.

On the other hand, a rotating member 4 is rotatably attached to the side surface 21 of the holder 2 with a pin 5, and a roller 6 is attached to one end of the rotating member 4. It protrudes inward from the holder 2 through a notch 2c formed on the upper surface thereof, so that it can come into contact with the upper surface of the cassette c mounted in the holder 2.

Further, an engaging part 4b is formed at the other end of the rotating member 4, and the engaging part 4b is connected to a hole formed in the upper surface of the main body 1 above the holder 2 when the cassette c is not inserted into the holder 2. Or, it is arranged so that it is located inside the recess 1c, and when the cassette c is inserted into the holder 2, it moves out of the recess 1c.

An operating piece 7 is rotatably attached to the side surface 21 of the holder 2 below the rotating member 4 by a shaft 8 at its substantially central portion, and is arranged between the protrusion 7c and the protrusion 2d on the holder 2. It is always rotationally biased counterclockwise by the coiled spring 9. Further, one end of the actuating piece 7 is formed with an engaging portion 7a that engages with a pin 11, which will be described later, and the other end 7a is connected to the upward rotation member 4 by a spring 10 that is stronger than the spring 9. There is.

Further, a pin 11 is disposed on the side plate in which the L-shaped guide groove is formed, with which the engaging portion 7a of the operating piece 7 collides when the holder 2 is lowered onto the cassette mounting section.

In addition, 12 in the figure is a stopper of the rotating member 4, and 13 is a stopper of the rotating member 4.
is a stopper of the actuating piece 7. That is, as shown in FIG.
is inserted, the rotating member 4 rotates clockwise, and the actuating piece 7 also makes a hole in the spring 9 and rotates clockwise, but after contacting the stopper 13, the spring 10 extends and eventually Thereafter, the rotating member 4 is pressed against the cassette c with a pressing force corresponding to the displacement of the spring 10.

The cassette holding device of the present invention is constructed as described above, and its operation will be described next.

FIG. 1 shows the state before the cassette c is installed in the holder 2. In this state, the holder 2 is located adjacent to the cassette insertion opening 1b of the front panel 1a, and the guides on the side of the holder 2 pin 2
a and 2b are located at the left end of the horizontal portions 31a and 31b of the L-shaped guide grooves 3a and 3b, respectively.

On the other hand, the operating piece 7 is rotated counterclockwise by a coiled spring 9, and the rotating member 4 is rotated via a spring 10.
The roller 6 is also rotated counterclockwise, and the roller 6 is projected into the holder 2 through the notch 2c of the holder 2, and its position is held by a stopper 12. Furthermore, the engaging portion 4b at the other end of the rotating member 4
is located in a recess 1c formed on the upper surface of the main body 1 side.

In this state, as shown in FIG. 2, when the cassette c is inserted into the holder 2 through the insertion opening 1b, the roller 6 of the rotating member 4 comes into contact with the slope C' formed on the upper edge of the front surface of the cassette c. By further inserting the cassette c, the roller 6 rides on the upper surface of the cassette c, and the engaging portion 4b at the other end of the rotating member 4
is removed from the recess 1c, making the holder 2 movable. Further, when the roller 6 rides on the upper surface of the cassette c, the rotating member 4 is rotated clockwise, but the spring 10 connecting the rotating member 4 and the actuating piece 7 moves the actuating piece 7 counterclockwise. The actuating piece 7 rotates together with the rotating member 4 against the spring 9, but the actuating piece 7
After the roller 6 contacts the stopper 13, the roller 6 is pressed against the cassette c only by the elastic force due to the extension of the spring 10, regardless of the spring 9.

That is, when holding the cassette c in the cassette holder 2, the roller 6 is pressed by the spring 10, but by keeping the extension (displacement) of the spring 10 small at this time, the pressing force against the cassette c can be reduced. , is set weakly so as not to interfere with insertion of the cassette into the cassette holder. Therefore, the cassette holder 2 will not move into the main body without the cassette c not being completely inserted into the cassette holder 2, and no unreasonable force will be applied to other members.

Note that until the cassette c is inserted into the holder 2, the engaging portion 4b at the other end of the rotating member 4 is located in the recess 1c. Even if the holder 2 is pressed into the main body 1, the engaging portion 4b acts as a stopper to prevent the holder 2 from moving.

When the cassette c is completely inserted into the holder 2, a well-known holder driving means (not shown) is operated by a micro switch (not shown), and the holder 2 is moved through the L-shaped guide grooves 3a, 3b and the guide pin 2.
It is brought to the cassette mounting section in the main body 1 while being guided by a and 2b.

FIG. 3 shows a state in which the cassette is mounted on the cassette mounting section of the holder 2, and the guide pins 2a and 2b of the cassette holder 2 are connected to the vertical portions 32a and 32b of the L-shaped guide grooves 3a and 3b. It is located at the bottom.

When the cassette holder 2 moves backward and downward within the main body as described above, the actuating piece 7 engages its engaging portion 7.
a collides with the fixing pin 11 on the inner plate of the main body 1 from above, causing it to rotate significantly counterclockwise, and as a result, the spring 10 is greatly stretched, and the displacement of the spring 10 is greater than the state shown in FIG. The force with which the rotating member 4 presses the cassette c increases accordingly.

The roller 6 of the rotating member 4 is pressed against the upper surface of the cassette c with a strong pressing force corresponding to the amount of displacement of the spring 10, and presses the cassette c in the cassette mounting part without causing slight wobbling or misalignment. It is.

FIG. 4 is a configuration diagram for explaining the mechanism for preventing incorrect insertion of the cassette, which is another function of the present invention. The slope C' on the upper edge of the front side pushes up the roller 6 of the rotating member 4, making it possible to insert the cassette c, but if the cassette c is inserted in the wrong direction by mistake, there will be no slope C'. The roller 6 of the rotating member 4 comes into contact with the front surface of the cassette c, preventing further insertion of the cassette c, and malfunction of the equipment due to incorrect insertion of the cassette can be completely prevented.

As described above, according to the cassette holder device of the present invention, the cassette holder is provided with a rotating member for holding down the cassette, and a spring member is provided for pressing the rotating member against the cassette in the cassette holder.
By controlling the amount of displacement of this spring member from the position of the cassette holder, when the cassette is installed in the cassette holder, a weak pressing force is used to suppress the insertion of the cassette so as not to interfere with the insertion of the cassette. When installed on the body, there will be no slight wobble or misalignment.
The structure was designed to suppress this with strong pressure contact, so
It has many advantages, such as completely eliminating rattling and misalignment of the cassette, and having a simple structure.
