Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a dust cover that opens and closes an insertion opening of an audio device into which a pack containing a storage medium is inserted and removed.

[Prior Art] Conventionally, this type of dust cover has a surface 1a that is simply a flat surface, as indicated by the reference numeral 1 in FIG. And this dust cover 1
is attached to the insertion port 3 of the pack P in the audio equipment 2 so as to open and close the insertion port 3. In this example, the audio equipment 2 is a DAT (digital audio tape recorder), and the pack P stores a magnetic tape. Install the dust cover 1 in the fixed position inside the insertion slot 3.
This is done by fitting the shaft portions 1b, 1b above both edges of the dust cover 1 into P0, P0, and the dust cover 1 itself has its shaft portions 1b, 1b.
It is designed to be able to rotate in the directions of arrows A and B around the axis O of.

When the pack P is not inserted, the dust cover 1 is in a vertical state as shown in the figure and closes the insertion opening 3. On the other hand, when the pack P is inserted, the flat front surface 1a is pushed by the pack P, and the dust cover 1 itself rotates in the direction of arrow A and retreats upward inside the insertion slot 3.
This opens the insertion port 3 and allows insertion of the pack P.

[Problems to be Solved] However, such a conventional dust cover 1 has the following problems.

The width l0 of the insertion slot 3 is set slightly larger than the width l1 of the pack P, so in order to insert the pack P smoothly, it is necessary to support and push it so that it is located in the center of the insertion slot 3. be.
However, it is difficult to position the pack P held in the hand at the center of the insertion slot 3, especially when the audio equipment 2 is mounted on a vehicle and is subject to various restrictions.

Also, pack P set at the back of insertion slot 3
When ejecting (see Figure 10), due to the play between the rear end surface 3a of the insertion slot 3 and the pack P, the pack P may come into contact with the end surface 3a. Eject failure occurs.

This invention solves such problems.

[Means for Solving the Problems] In order to solve the above problems, the dust cover for audio equipment of this invention has a shaft portion on one end side, and is suitable for use in audio equipment into which a pack containing a storage medium is inserted and removed. A dust cover that is rotatably attached to the insertion slot, and when the front side is pressed by the pack to be inserted, the free end side rotates inside the insertion slot around the shaft, opening the insertion slot. In a dust cover for a device, a protrusion is provided on at least one of the left and right sides of the front surface of the dust cover to guide the side surface of the pack during insertion and removal and to regulate the position of the pack in the width direction.

[Function] According to the dust cover of the audio equipment of this invention,
A protrusion is provided on at least one of the left and right sides of the front surface of the dust cover to guide the side of the pack and regulate the widthwise position of the pack during insertion and removal, so that the pack is positioned in the width direction when inserted and ejected. There is no slippage, and pack insertion and ejection operations are smooth.

[Example] Hereinafter, an example of this invention will be described based on FIGS. 1 to 8. Note that the same parts as those in the conventional example described above are given the same reference numerals, and the explanation thereof will be omitted.

1 to 7 are explanatory diagrams of an embodiment of this invention.

The dust cover 11 of this embodiment has a front surface 11
Protrusions 12, 12 having a predetermined shape, which will be described later, are integrally molded on both the left and right sides of a. Further, above both side edges of the dust cover 11, shaft portions 11b, 11
b is provided, and by fitting the shaft portions 11b, 11b into fixed positions P0, P0 inside the insertion port 3 of the audio equipment 2, the dust cover 11 itself can be opened. Shaft portion 11b,
It is designed to be able to rotate in the directions of arrows A and B around the axis O of 11b.

The left and right protrusions 12, 12 have a left-right symmetrical shape. Therefore, representing the protrusions 12, 12 on the right side,
Its shape will be explained with reference to FIGS. 5 to 7.
These protrusions 12, 12 are formed into a substantially rectangular parallelepiped as a whole, and when viewed from the front (FIG. 5),
The upper end surface 12a is curved, and the lower left corner is cut off to form an inclined surface 12b.
Further, the end surface 12a has a curved shape when viewed from the side (FIG. 6).

The left protrusion 12 has a symmetrical shape with the right protrusion, and they are spaced apart by a predetermined distance l2.
(see Figure 4). This interval
l2 is set slightly larger than the width l1 of the pack P, so that the pack P fits between the left and right protrusions 12, 12.

Next, the effect will be explained.

The dust cover 11 is in the vertical position shown in FIG. 1 and closes the insertion port 3 when the pack P is not inserted, as in the conventional example described above. When the pack P is inserted, the front face 11a is pushed by the pack P, and the dust cover 11 itself rotates in the direction of arrow A and retreats upward inside the insertion slot 3. Open it to allow the pack P to be inserted.

At the initial stage of inserting the pack P, the front end of the pack P is attached to the front surface 11a of the dust cover 11.
Press and rotate it in the direction of arrow A,
It gradually enters between the left and right protrusions 12 (see Fig. 2). Its entry is protrusion 1
Since the end surfaces 12a, 12a of Nos. 2 and 12 are curved, it is smoothly guided in the left-right direction along those curved surfaces. Pack P stuck between protrusions 12 and 12
is inserted while being guided by its protrusions 12, 12. In other words, the pack P is inserted while its position is restricted in the left-right direction. Therefore, the pack P is positioned at the center in the width direction of the insertion opening 3 and can be inserted smoothly. When the pack P is inserted to the set position at the back of the insertion opening 3, the dust cover 11 is held open by a mechanism (not shown). Further, at this time, it is also possible to close the dust cover 11.

When ejecting the pack P, in the initial stage, the rear end of the pack P should be
2 (see Figure 3). The intrusion is caused by the inclined surfaces 12a of the protrusions 12, 12,
12a, it is carried out smoothly as it is guided in the left and right direction. Therefore, in the initial stage of ejecting the pack P, there is no problem that the rear end of the pack P hits the rear end surface of the insertion opening 3, causing ejection failure. While the pack P is being ejected, its both sides are again guided by the protrusions 12, 12, and its position is regulated in the left-right direction. After the pack P is completely ejected, the dust cover 11 rotates in the direction of arrow B and returns to the state shown in FIG. 1 in which the insertion port 3 is closed again.

FIG. 8 is an explanatory diagram of another embodiment of this invention. This figure is similar to FIG. 7, and as is clear from the figure, in this embodiment, the inner corner of the protrusion 12 is cut off to form the inclined surface 12c. This inclined surface 12c guides the pack P in the vertical direction when it enters between the protrusions 12, 12 in the initial stage of inserting the pack P and the initial stage of ejecting it. be. This makes insertion and ejection of the pack P even smoother.

In addition, in the case of the above embodiment, the dust cover 11
Although the protrusions 12, 12 are provided on both the left and right sides of the front surface 11a, they may be provided on at least one of the left and right sides. In this case, both sides of the pack P are guided by one of the protrusions 12 and the inner surface of the insertion port 3 located on the opposite side of the protrusion 12, thereby regulating the position of the pack P in the width direction.

In addition, the dust cover of this invention can be widely applied to various electrical devices, such as:
The pack may house storage media such as magnetic disks or optical disks, and the electrical equipment may play back the stored data.

[Effects] As explained above, according to the dust cover of the audio equipment of this invention, there is a structure on at least one of the left and right sides of the front surface of the dust cover that guides the side of the pack when it is inserted or removed. Since the protrusion regulating the position is provided, the side surface of the pack is guided by the protrusion of the dust cover immediately after insertion or ejection starts, and the widthwise position of the pack is regulated.

Therefore, when inserting the pack, the pack is inserted in the correct posture without having to manually align the pack with the center of the insertion slot, and when ejecting the pack, the back end of the pack comes into contact with the end of the insertion slot. The occurrence of ejection failure can be reliably prevented, and insertion and ejection operations can be smoothly performed without the pack shaking in the width direction.

Therefore, the dust cover for audio equipment of this invention is extremely suitable as a dust cover for audio equipment for vehicles, which are subject to various restrictions, and also contributes to safe driving.
