BACKGROUND OF THE INVENTION
The present invention relates to a portable information processing apparatus such as a notebook personal computer (hereinafter abbreviated as a notebook personal computer).
[0002]
[Prior art]
FIG. 3 is a perspective view showing an external appearance of a general notebook computer, and FIG. 4 is a bottom view of the main body frame. That is, as is well known, a notebook personal computer which is a portable information processing apparatus has a liquid crystal display 2 attached to an end portion on the back side of the main body frame 1 via a hinge 2 so as to be opened and closed. On the upper surface 1a of the main body frame 1, there are a large number of input keys 4 and a pointer device 5 provided in front of the center near the front side. The main body frame 1 incorporates an HDD (Hard Disk Drive) 6, a CD-ROM drive, a DVD-ROM drive, etc. (not shown), and a bottom surface 1b of the main body frame 1 has a plurality of rubber legs. 7 is protrudingly provided.
[0003]
The rubber legs 7 prevent the main body frame 1 from slipping or rattling, the bottom surface 1b of the main body frame 1 or the desk from being damaged, and reducing vibration when driving a CD / DVD-ROM drive, etc. As shown in FIG. 5, conventionally, the rubber legs 7 are disposed in the vicinity of the four corners of the bottom surface 1 b in consideration of the stability of the main body frame 1.
[0004]
[Problems to be solved by the invention]
By the way, when such a notebook personal computer is moved on a desk or placed on a desk, the HDD 6 may be damaged due to an impact of dropping due to negligence. FIG. 5 shows the occurrence of such a drop. That is, as shown in FIG. 5A, the main body frame 1 is lifted by hand, for example, at the end on the side where the HDD 6 is built, and In the process of being moved by dragging on the upper surface of 8, the frictional force of the rubber leg 7 against the upper surface of the desk 8 is large, so that the hand slips if the main body frame 1 is not firmly held, as shown in FIG. , It may be overlooked.
[0005]
In this case, the lifting height of the end portion of the main body frame 1, that is, the drop height H is 50 to 120 mm at most, but at the time of impact input due to the drop or the like shown in FIG. Since the rubber legs 7, 7 arranged in the vicinity are in a doubly-supported support state, the main body frame 1 is difficult to bend and when the raised rubber legs 7 (7 a) collide with the upper surface of the desk 8. The impact received by the HDD 6 was great, causing damage.
[0006]
Needless to say, the HDD 6 is an important device as a large-capacity storage device in this type of information terminal processing apparatus, and if it is damaged, it becomes impossible to read program data and various data from the hard disk, and for repairing the damage Since a great deal of cost and time are required, it has been desired to improve impact resistance as a structure that can reduce impact caused by dropping as much as possible.
[0007]
In general, in order to increase the cushioning property by the rubber legs 7, it is conceivable to increase the thickness (height). However, in this case, since the degree of freedom in the horizontal direction of the main body frame 1 increases, There arises a new problem that the amplitude of horizontal vibration accompanying the driving of a DVD-ROM drive or the like becomes large. In addition, increasing the height of the rubber legs 7 is also contrary to the requirement in precision instruments such as notebook computers that are required to be thin.
[0008]
The present invention has been made in view of the above-described problems, and its technical problem is that the impact caused by accidental dropping is effectively reduced by the rubber legs, and precision devices such as HDDs inside the main body are damaged. It is to make it difficult.
[0009]
[Means for Solving the Problems]
Conventional technical problems can be effectively solved by the present invention.
That is, the portable information processing device according to the invention of claim 1 is a portable information processing device in which a precision device is built in the vicinity of the first corner of the body frame, and is separated from the precision device on the bottom surface of the body frame. Rubber legs are respectively attached in the vicinity of the second to fourth corners , and the first corners are separated by rubber legs attached in the vicinity of two edges sandwiching the first corners. It is supported by holdings . And with this arrangement of rubber legs, the body frame itself is buffered, and the acceleration of the impact acting on this precision device is effective when the end of the body frame on the precision device side is lifted and dropped. It will be relaxed.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a bottom view of a main body frame of a notebook personal computer as a portable information processing apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes a main body frame of a notebook personal computer that is a portable information processing device, the lower side of the figure is the front side, the upper side of the figure is the back side, and one end of the front side of the main body frame 1. An HDD (Hard Disk Drive) 6 which is a precision device to be protected according to the present invention is built in the vicinity of the first first corner 1c. The notebook personal computer itself is basically the same as that shown in FIG.
[0011]
A plurality of rubber legs 11 to 15 are attached to the bottom surface 1 b of the main body frame 1 along the vicinity of the outer periphery thereof. The height of each rubber leg 11-15 is the same, and the lower surface is formed flat.
[0012]
Among the rubber legs 11 to 15, the rubber leg 13 is disposed in the vicinity of the second corner 1 d on the opposite side of the HDD 6 on the front side, and the rubber legs 14 and 15 are third left and right ends on the rear side. It is arranged near the corner 1e and the fourth corner 1f. Further, the rubber legs 11 and 12 on the built-in position side of the HDD 6 have Lx as the length of the front edge 1g on the bottom surface 1b of the main body frame 1 and the length of the side edge 1h extending from the first corner 1c. Let Ly be a rectangular area (area shown with fine dots in FIG. 1) a having two side lengths Lx / 4 and Ly / 4, respectively, sandwiching the first corner 1c. Has been.
[0013]
That is, the rubber leg 11 is disposed in the vicinity of the front edge 1g of the bottom surface 1b of the main body frame 1, and the distance L1 from the first corner 1c on the HDD 6 built-in position side to the rubber leg 11 is L1 ≧ Lx / 4 The rubber leg 12 is disposed in the vicinity of the side edge 1h of the bottom surface 1b of the main body frame 1, and the distance L2 from the first corner 1c to the rubber leg 12 is L2 ≧ Ly / 4.
[0014]
FIG. 2 shows a situation in which the notebook type personal computer with the rubber legs 11 to 15) arranged as described above is dropped excessively when moved on the desk 8 or placed on the desk 8. It is explanatory drawing which shows. According to the above-described configuration, as shown in FIG. 2A, the process of moving the main body frame 1 by lifting the edge 1h on the side where the HDD 6 is built up by hand and dragging it over the desk 8. In the case where the hand slips and is removed as shown in FIG. 2B, the acceleration acting on the HDD 6 due to the impact is greatly reduced as compared with the conventional case. For this reason, it is possible to prevent the occurrence of data unreadable due to the damage of the HDD 6.
[0015]
This is because the portions on the first corner 1c side of the rubber legs 11 and 12 provided at positions separated from the first corner 1c by the distances L1 and L2 are not supported by the rubber legs, that is, cantilevered. Therefore, when the rubber legs 11 and 12 collide with the upper surface of the desk 8, the main body frame 1 bends as shown by a one-dot chain line and two-dot chain line in FIG. This is considered to be because the shock to the HDD 6 built in the vicinity of the corner 1c is absorbed. Further, since the deformation amount of the rubber legs 11 and 12 when colliding with the upper surface of the desk 8 is larger than that when the rubber legs are provided in the vicinity of the first corner 1c, it is considered that the buffering function is also increased. .
[0016]
In addition, according to the above-described configuration, it is not necessary to increase the height (wall thickness) of the rubber legs 11 to 15 so that the rubber legs 11 to 15 themselves have a low spring constant in order to improve buffering properties. For this reason, the degree of freedom in the horizontal direction of the main body frame 1 does not increase, and therefore, the amplitude of horizontal vibration accompanying the drive of a CD / DVD-ROM drive or the like does not increase.
[0017]
[0018]
[0019]
As indicated by reference numeral 16 in FIG. 1, in addition to the rubber legs 11-15, a rubber leg having a height smaller than that of the rubber legs 11-15 may be attached in the vicinity of the first corner 1c. . That is, the rubber legs 16 are normally lifted from the upper surface of the desk 8 or the like, but are dropped from the state in which the main body frame 1 is lifted obliquely as shown in FIG. When 1 is bent as shown by a one-dot chain line and two-dot chain line in FIG. 2 (B), when a certain amount of deflection is reached, the rubber leg 16 comes into contact with the upper surface of the desk 8 or the like in a buffering manner. The excessive bending of the main body frame 1 is prevented.
[0020]
Similarly, such a rubber leg may be positioned and attached between the rubber legs 13 and 15 as indicated by reference numeral 17, for example.
[0021]
【The invention's effect】
In the portable information processing apparatus according to the first aspect of the present invention, the first corner is formed on the bottom surface of the main body frame by rubber legs provided in the vicinity of two edges sandwiching the first corner on the precision device side. Because it is a cantilever-supported structure, when the end of the precision device side of the main body frame is lifted and tilted, the main body frame itself flexes on the precision device side to provide cushioning. Therefore, the impact acting on the precision device can be mitigated and the breakage can be effectively prevented.
