Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detachable mechanism for attaching or detaching a data storage device used in a data processing device to or from a data processing device. For example, the present invention relates to a traffic information incorporated in a vehicle navigation system. The present invention relates to a hard disk attaching / detaching mechanism in which information such as is stored.

[0002]

2. Description of the Related Art In recent years, a space-saving and large-capacity hard disk has been regarded as a promising data storage device for in-vehicle information devices. A data storage device using this hard disk is disclosed in Japanese Patent Application Laid-Open No. H11-73240. A conventional hard disk attaching / detaching mechanism disclosed in this publication will be described with reference to FIG. 8A and 8B show the configuration of the hard disk 51 when it is installed in the data processing device. FIG. 8A is a front view of the hard disk 51, FIG. 8B is a bottom view of FIG. () Is a right side view of (a).

[0003] As shown in FIG. 8, in the above-mentioned conventional mechanism for attaching and detaching the hard disk 51, the hard disk 51 is fitted into a holder 53 to which an arm 52 is attached.

[0004] Specifically, the holder 53 has a substantially rectangular shape, and has a configuration in which side walls 53a are provided on both long sides of the rectangle. The holder 53 is formed by punching a metal plate or the like, and has a thin configuration so that the outer shape of the hard disk 51 is substantially the same as that of the hard disk 51 when the hard disk 51 having a substantially rectangular parallelepiped is accommodated in the holder 53. ing. Also, the arm 52
Is formed by bending a piano wire or the like, and is rotatably fitted into a hole 53b provided at an end of both side wall plates 53a of the holder 53.

[0005] The hard disk 51 fitted into the holder 53 as described above is inserted into the accommodating space of the data processing device together with the holder 53. Thereby, the connector pin provided at the tip of the hard disk 51 in the insertion direction is directly connected to the connector of the data processing device, so that the hard disk 51 can be mounted.

On the other hand, when the hard disk 51 is accommodated in the data processing device, the arm 52 can be pulled out of the accommodation opening of the data processing device. For this reason, by pulling the arm 52, the connector pin is disconnected from the connector, and the hard disk 51 can be removed from the data processing device.

[0007]

It is desirable that the hard disk can be easily replaced in case of data update or failure.

However, in the above prior art,
Since the connection between the hard disk 51 and the data processing device is made by a large number (for example, forty or more) of connector pins, there is a problem that a large force is required to pull out the connector pins from the connector. For example, when there are forty connector pins, about 5 kgf or more is required as a force for pulling the arm 52.

Further, in the above prior art, the arm 52 is formed by bending and fitted to both ends of the holder 53. Specifically, the arm 52
Is a configuration in which a supporting leg 52a is provided by bending both ends of one piano wire in the same direction, and the supporting leg 52a is further bent inward to form a connecting portion 52b that can be fitted into the hole 53b of the holder 53. Has become.

The arm 52 having such a configuration is used when the hard disk 51 is detached from the data processing device. Therefore, when the hard disk 51 is mounted in the storage space of the data processing device, the arm 52 of the data processing device is used. You have to be outside.

However, since the support leg 52a is formed straight, the arm 52 is located at an incorrect position when the hard disk 51 is attached and detached.
2 may come into contact with the hard disk 51 and may fit into the housing space together with the hard disk 51 and the holder 53.

The present invention has been made in view of the above problems, and has as its first object to make it possible to easily remove a data storage device from a data processing device.

It is a second object of the present invention to prevent the arm from being fitted into the accommodation space of the data processing device.

[0014]

In order to solve the above problems,
According to the first aspect of the present invention, the arm (8) has the support leg (8) rotatably connected to each of both sides of the holder (9) in the width direction intersecting the insertion direction.
a), the supporting legs being connected to the holder when the data storage device is inserted into the receiving space and the supporting legs are rotated in a direction in contact with the window frame of the window. It is characterized in that it is bent in a direction opposite to the direction in which it is rotated at a position at a predetermined distance from the part where it is turned.

As described above, by bending the support leg at a predetermined position, the holder and the data storage device are accommodated in the case by using the leverage with the portion of the support leg in contact with the window frame of the window as a fulcrum. Can be taken out of space. As described above, since the lever principle is used, the holder and the data storage device can be taken out with a relatively small force. Thus, the data storage device can be easily taken out of the data processing device.

For example, there is a case where a connector pin is arranged at the leading end of the data storage device in the insertion direction. In this case, the connector pin is fitted into the connector arranged on the case side. In such a case, the connector pins must be pulled out of the connector, and a large force is required. For this reason, by making it possible to take out the data storage device based on the above-mentioned leverage principle, it is possible to make it easy to take out even in such a case.

For example, assuming that a portion of the arm connecting the two supporting legs is a connecting portion (8c), a portion of the supporting leg bent from a portion connected to the holder (8c). The distance (B) from the bent portion to the end on the connecting portion side may be configured to be larger than the distance (A) to 8d).

According to the third aspect of the present invention, the arms are rotatably connected to the support legs (8) on both sides of the holder in the width direction intersecting the insertion direction.
a), the supporting leg portion has a portion projecting in a direction orthogonal to the insertion direction of the data storage device when the arm is rotated to the most rotated position, and the projecting portion Thus, the data storage device is restricted from being accommodated in the accommodation space.

As described above, if the support leg has a portion projecting in a direction orthogonal to the insertion direction of the data storage device when the arm is rotated most, then this portion inserts the data storage device. In such a case, the insertion of the data storage device can be restricted. Thus, the data storage device together with the arm can be prevented from being fitted into the accommodation space.

For example, when the data storage device is inserted into the accommodation space and the support leg is rotated in the direction in contact with the window frame of the window, the data storage device is connected to the holder. At a predetermined distance from the part
The support legs may be bent in a direction opposite to the direction in which the support legs are rotated.

In addition, as shown in claim 5, the arm is constituted by a single rod-shaped member, both ends of the rod-shaped member are bent inward, and the bent both sides are bent in the same direction. A part can be formed.

Further, when the data storage device has a substantially rectangular parallelepiped shape, a bottom surface (9b) facing three surfaces of the data storage device and both side wall plates of the bottom surface are provided. (9a), a crank bent portion (9f) having a crank shape formed on both side wall plates after being bent outward of the holder and further bending the bent portion inward of the holder. )
By fitting the distal end of the arm into the hole (9g) formed in the crank bent portion, the arm can be rotatably supported by the holder.

In this case, the rotation of the arm can be restricted by the crank bending portion by fitting the distal end portion of the arm into the hole of the crank portion from the inside of the holder. is there.

Note that the reference numerals in parentheses described above indicate the correspondence with reference numerals in the drawings shown in the embodiments described later.

As described above, when the arm 8 falls down toward the upper surface of the hard disk 3, the support leg 8
A portion between the end of the connecting portion 8b and the bending point 8d contacts the crank bending portion 9f so that the rotation of the arm 8 is restricted. For this reason, as shown in FIG. 7, the portion of the support leg 8a from the bending point 8d to the end on the side of the connecting portion 8c is raised with respect to the holder 9, and this portion is inserted when the hard disk 3 is inserted. Case 1
Touches the edge of the upper surface of the. Therefore, the hard disk 3
Is restricted, and the hard disk 3 can be prevented from being completely inserted into the accommodation space while the arm 8 remains in a collapsed state.

(Other Embodiments) In the above embodiment, the support pins 8a of the arm 8 are bent so that the connector pin 3f can be pulled out of the connector 10 with a relatively small force by leverage. Alternatively, the arm 8 may be formed in advance so as to have a shape to which this principle can be applied.
