DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device having a support frame fixed inside a housing and components for the electronic device which enter through an opening formed in the housing and are received by the support frame. . The components for electronic devices may include components such as a recording disk drive and a power supply. Here, the recording disk drive includes, for example, a magnetic disk drive such as a hard disk drive (HDD) and a floppy disk drive (FDD), an optical disk drive such as a DVD (digital video disk) drive, and a magneto-optical disk (HDD). MO) drive may be included.

2. Description of the Related Art In a computer device such as a POS terminal, a screw is used to fix a magnetic disk drive such as an HDD or an FDD to a support frame in a housing. In such screwing, for example, Japanese Patent Laid-Open No. 6-2
As shown in Japanese Patent No. 36669, an elastic member such as rubber or a spring is interposed between the support frame and the magnetic disk drive. When the elastic member is sandwiched in this way, it is expected that vibration and shock applied to the housing will be absorbed by the elastic member.

[0003] If the vibration or impact is sufficiently absorbed by the elastic member, the vibration of the magnetic disk drive can be suppressed. It is possible to prevent the magnetic disk drive from malfunctioning or hindering reading and writing of information due to vibration and shock applied to the housing.

[0004]

In the conventional fixing method,
Although an elastic member such as rubber or a spring is interposed, the magnetic disk drive is attached to the support frame by a highly rigid screw, so that vibration and impact applied to the housing are transmitted to the magnetic disk drive through the screw. Therefore, the vibration of the magnetic disk drive could not be suppressed as expected. In addition, when replacing the magnetic disk drive, much time and labor has to be devoted to removing and installing the screws.

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and has been made in consideration of an electronic device capable of reliably protecting a recording disk drive device from vibration or impact applied to a housing, and a recording disk drive device used in such an electronic device.

Such a recording disk drive unit can be easily attached to and detached from, for example, a support frame fixed inside the housing. Moreover, according to the adoption of such a unit structure, it is possible to avoid the loss of the screw or the indirect member as the connecting tool when carrying the device.

In such a recording disk drive unit, a knob protruding forward from the recording disk drive along the moving direction of the slide movement may be formed on the indirect member. According to such a knob, it is possible to relatively easily pull out the recording disk drive from the opening of the housing using the sliding movement of the recording disk drive.

According to the second aspect of the present invention, a support frame fixed to the inside of the housing, a recording disk drive device which enters through an opening formed in the housing and is received by the support frame, and a recording disk drive device And a knob fixed to the outer surface of the recording disk drive and protruding forward from the front surface of the recording disk drive device facing the opening.

According to such an electronic device, by using the knob protruding forward of the recording disk drive,
It is relatively easy to remove the recording disk drive from the housing. Therefore, workability is remarkably improved at the time of replacement of the recording disk drive device and at the time of maintenance.

In order to realize such an electronic apparatus, for example, a recording disk drive, a slide surface defined by an outer surface of the recording disk drive, which causes the recording disk drive to slide, and a sliding direction of the slide movement. A recording disk drive unit may be provided that includes a knob protruding forward from the recording disk drive along.

Further, the electronic apparatus according to the second invention further includes an indirect member received by the support frame, an elastic member incorporated in the indirect member, and a connecting member for connecting the recording disk drive to the elastic member. You may. According to such a configuration, contact between the recording disk drive connected to the elastic member and the indirect member or the support frame can be avoided. Vibration and shock transmitted from the support frame to the indirect member are absorbed by the elastic member and do not reach the recording disk drive. Therefore, the shock resistance and the earthquake resistance of the electronic device can be greatly improved.

The housing 12a of the terminal body 12 includes a housing 12
An opening 16 communicating with the internal space of a is formed. Case 12
A hard disk drive (HDD) 17 is arranged in the internal space a, for example, as shown in FIG. HD
D17 is also connected to a CPU (Central Processing Unit) and a power supply unit (both not shown) housed in the housing 12a. For connection, for example, connectors 18 and 19 may be used. The HDD 17 stores, for example, various information obtained at the time of sale of a product, in addition to a software program executed by the CPU when implementing the POS system.

On the outer surface of the HDD 17, an H
A knob 21 projecting forward from the front surface of the DD 17 is attached. This knob 21 is, for example, 1
A pair of plate-shaped finger receivers 22 is provided. Each finger receiver 22 has an interval S
To face the edge of the opening 16. In such an interval S, a worker's finger can be accepted when putting the HDD 17 in and out.

The HDD 17 has a support 23 made of metal, for example.
Above is received, for example, in a support frame 24 made of sheet metal. An opening 1 is provided between the HDD 17 and the support frame 24.
A guide mechanism 25 for guiding the HDD 17 from 6 to a predetermined fixed position and a lock mechanism 26 for holding the HDD 17 at the fixed position are provided. When the lock mechanism 26 is released, the HDD 17 can move forward from the fixed position toward the opening 16 while being guided by the guide mechanism 25 in the same manner.

FIG. 3 schematically shows the HDD 17 removed from the support frame 24. As is apparent from FIG. 3, the guide mechanism 25 includes a flat plate body 29 of the support frame 24 which is superimposed on the surface of the support table 23 and fixed to the support table 23 by, for example, screws 28, and both sides of the flat plate body 29. And first and second guide walls 30 and 31 rising from the first and second guide walls. The space occupied by the HDD 17 is defined between the first and second guide walls 30 and 31. This occupied space extends linearly from the opening 16 described above. The distance between the first and second guide walls 30 and 31 may be appropriately set according to the width of the HDD 17.

At the upper ends of the first and second guide walls 30, 31, regulating plates 32, 33 facing the flat plate body 29 are formed. At the front ends of the regulating plates 32, 33, there are formed introduction pieces 34, 35 which gradually move away from the flat plate body 29 toward the front, that is, toward the opening 16. First and second guide walls 3
At one end, that is, at the rear end of the 0, 31, regulating pieces 36, 37 that extend in the direction approaching each other are formed.

On the surface of the flat plate body 29, indirect members 38 and 39 made of synthetic resin such as nylon are received. A first slide surface 40 that contacts the surface of the flat plate main body 29 is defined on the indirect members 38 and 39. At this time,
The indirect member 38 received by the flat plate body 29 is guided by the first guide wall 30 while being sandwiched between the flat plate body 29 and the regulating plate 32. Similarly, the indirect member 39 is
It is guided by the second guide wall 31 while being sandwiched between the flat plate body 29 and the regulating plate 33. Indirect members 38, 39
The second and the first and second guide walls 30 and 31
A slide surface 41 and a third slide surface 42 that contacts the restriction plates 32 and 33 are formed. The indirect members 38 and 39 guided in this manner can realize sliding movement in the front-rear direction 43 along the first and second guide walls 30 and 31.

A pair of front and rear elastic members 44 is incorporated in each of the indirect members 38 and 39. The elastic member 44 is, for example, a screw 4
The HDD 17 is connected to an outer surface (for example, a side surface) of the HDD 17 by a connecting tool such as an adhesive or an adhesive. As a result, the elastic member 44 is fixed to the outer surface of the HDD 17, so that the indirect members 38, 3
9 is attached to the outer surface of the HDD 17. The two joint members 38, 39 are respectively connected to the first and second guide walls 30, 3
1 and the guide plates 32 and 33, the HD
D17 can realize sliding movement in the front-back direction 43 within the support frame 24.

An elastic plate 46 protruding forward along the moving direction of the sliding movement is integrally formed with the indirect members 38 and 39. The lock mechanism 26 includes a protrusion 47 formed on the surface of the elastic plate 46 and a receiving hole 48 formed integrally with the support frame 24 to receive the protrusion 47. The projecting piece 47 has a vertical surface 47a that rises vertically from the surface of the elastic plate 46, and an inclined surface 47b that extends rearward from the upper end of the vertical surface 47a. The above-described finger receiver 22 is formed integrally with the distal end of the elastic plate 46.

For example, as shown in FIG.
4 includes a fixed plate 51 pressed against the outer surface of the HDD 17 by the holding force of the screw 45, and a pair of elastic members 52 connecting the fixed plate 51 to the indirect members 38, 39. The indirect members 38 and 39 and the HDD 17 are not connected to each other except for the elastic member 44. Moreover, the HDD 17 includes not only the indirect members 38 and 39 but also the support frame 24 and the screw 2.
No contact with 8. As a result, even if the vibration is transmitted from the housing 12 to the support base 23 or the support frame 24, the transmitted vibration is absorbed by the elastic member 44. HDD17
The vibration does not reach until. Such vibration is caused, for example, when the drawer 11 is opened and closed, or when an operator collides with the POS terminal 10 when carrying in a product.

Here, the HDD 1 is connected to the POS terminal 10.
Assume a scene in which 7 is incorporated. Prior to this assembling operation, a pair of indirect members 38 are attached to the HDD 17 with screws 45.
39 is attached. When the indirect members 38 and 39 are attached to the HDD 17 in advance in this way, the HDD 17 and the indirect members 38 and 39 can be integrally treated as an HDD unit. Inconveniences such as loss of the indirect members 38 and 39 and the screws 45 can be avoided as compared with a case where both are carried separately.

When such an HDD unit enters through the opening 16 of the housing 12a, for example, as shown in FIG. 5, the guide mechanism 25 guides the HDD unit 54 toward a fixed position. The HDD unit 54 slides in the retreating direction toward the fixed position using the pushing force applied by the assembly operator. When the HDD unit 54 reaches the fixed position, the rear ends of the indirect members 38 and 39 collide with the regulating pieces 36 and 37 of the support frame 24. This restriction piece 36,
The retreat of the HDD unit 54 is regulated by the function of the 37.

When the HDD unit 54 slides in the retreating direction in this manner, in the lock mechanism 26, for example, as shown in FIG. Touch one end. Further HDD
When the unit 54 retreats, as shown in FIG. 6B, the inclined surface 47 that continues to contact one end of the support frame 24
With the help of b, the elastic plate 46 is deformed. Therefore, the protrusion 47 does not prevent the HDD unit 54 from moving backward.

Subsequently, when the HDD unit 54 reaches the fixed position, the projecting piece 47 enters the receiving hole 48 of the support frame 24 by utilizing the elastic restoring force of the elastic plate 46. When the projection 47 is received in the receiving hole 48 in this manner, HD
Advancement of the D unit 54 can be prevented. HD
When the D unit 54 advances, the vertical surface 47a of the projection 47
This is because even if the inner wall of the receiving hole 48 comes into contact with the elastic plate 46, no elastic deformation of the elastic plate 46 is caused.

When taking out the HDD unit 54 from the POS terminal 10, as shown in FIG.
The knob 21 facing the opening 16 is picked. At this time, FIG.
As shown in (b), when the finger supports 22 are brought close to each other with the help of the elastic deformation of the elastic plate 46, the projection 4
7 can be detached from the receiving hole 48. In this manner, while the protruding piece 47 is detached from the receiving hole 48, the pick 2
When 1 is pulled out from the opening 16, the HDD unit 54 advances from the fixed position while being guided by the guide mechanism 25. Thus, the HDD unit 54 can be taken out of the housing 12a relatively easily.

In the above removal operation, H
Connectors 18 and 19 may remain connected to DD 17. Connectors 18 and 19 together with HDD unit 54
Can be taken out of the housing 12a, the housing 1
HDD unit 54 can be easily opened without opening 2a itself.
Can be realized. For example, workability is remarkably improved when replacing the HDD 17 or performing maintenance.

The support frame 24 for receiving the HDD unit 54 is, for example, as shown in FIG. 8, a first frame member 55 fixed to the above-mentioned support 23, and similarly fixed to the support 23, and A second frame member 56 that defines an occupied space of the HDD 17 between itself and the frame member 55
And may be composed of According to the first and second frame members 55 and 56, the first guide wall 30 and the regulating plate 32 for receiving the indirect member 38 and the second guide wall 31 and the regulating plate 33 for receiving the indirect member 39 are separated from each other. Can be done. Therefore, according to the employment of the first and second frame members 55 and 56, the space between the first and second frame members 55 and 56 can be freely set, so that occupied spaces of various sizes are defined. It is possible to do. As a result, the support frame 24 has various sizes of HD even when the common indirect members 38 and 39 are used.
D17 can be accepted.

As is clear from FIG. 9A, the elastic body 52 described above hardly absorbs vibration in the vertical direction 59 as compared with the front-rear direction 57 and the horizontal direction 58 along the sliding direction of the HDD 17. On the other hand, as shown in FIG. 9B, if a combination of a pair of elastic bodies 61 and 62 that are easily deformed in different directions is sandwiched between the indirect members 38 and 39 and the fixing plate 51, The vibration in the vertical direction 59 as well as the vibration in the front-rear direction 57 and the horizontal direction 58 can be sufficiently absorbed. However, such an elastic body 61,
The combination of 62 may be replaced by a metal spring 63 or the like, for example, as shown in FIG.

As long as the above-described elastic member 44 can be incorporated, the indirect members 38 and 39 may be made of a synthetic resin material as described above, and may be made of a metal material such as aluminum. You may.
