Abstract

PROBLEM TO BE SOLVED: To provide a mobile information processing unit able to be used in a state that a CD driver or the like can keep a high-speed rotation without giving adverse effect on a hard disk driver by suppressing vibration caused by a recording disk with a deviated gravity center mounted on the CD driver or the like and rotated at a high-speed. SOLUTION: When the disk with a deviated gravity center is mounted on the CD driver 4 and the CD driver 4 is rotated at the highest speed, the CD driver 4 is vibrated at the same frequency as a frequency equivalent to the rotating speed. The vibration energy caused by the vibration is propagated through a frame 2, a pendulum 5 whose resonance frequency is set to be the vibrating frequency is resonated to consume the vibration energy so as to suppress the delivery of the vibration to the hard disk driver 3.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable information processing apparatus such as a notebook personal computer, and more particularly, to a portable information processing apparatus having a built-in disk drive such as a hard disk drive, CD drive, or DVD drive as a storage device. It concerns the device.

2. Description of the Related Art In recent years, even in a portable information processing device such as a notebook personal computer, a disk drive device such as a CD (compact disk) drive device or a DVD (digital video disk) drive device is mainly mounted as a storage device. And its rotation speed is increasing year by year. Further, in a hard disk drive device which is conventionally mounted as a fixed storage device, its storage capacity is increasing year by year, and since the density is increased, durability against external vibrations is reduced.

Hereinafter, a conventional portable information processing apparatus will be described with reference to the drawings.

FIG. 2 is an exploded perspective view of a conventional portable information processing apparatus. In FIG. 2, reference numeral 21 denotes a main body of the portable information processing apparatus.
A metal material such as magnesium is used to rotatably support the device. The lower housing 21b includes a hard disk drive 24 using a fixed recording disk and a CD using a detachable recording disk.
(Compact disk) A disk drive device such as a drive device 25 is built in and fixed.

[0005]

However, in the above-mentioned conventional portable information processing apparatus, the CD drive 2
When a recording disk (for example, the center hole of the recording disk is slightly deviated from the center of the outer shape of the recording disk) mounted on the disk 5 and played back, the cycle is determined according to the rotation speed of the CD drive device 25. Vibration occurs. This vibration increases as the rotational speed of the CD drive device 25 increases. This vibration is transmitted to the hard disk drive 24. If the hard disk drive 24 is performing a read / write operation at this time, a read error or a write error occurs. In the worst case, the writing operation to a different part is performed by the vibration, and as a result, the already written data may be damaged. In order to avoid this, in such a conventional portable information processing apparatus, when a recording disk having a deviated center of gravity is mounted, it is necessary to reduce the number of revolutions of the CD drive device 25 to reduce vibration. .

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and suppresses vibration caused by mounting and rotating a recording disk having a center of gravity biased in a CD drive device or the like, thereby adversely affecting a hard disk drive device. It is another object of the present invention to realize use of a CD drive device or the like while maintaining high-speed rotation.

[0007]

In order to solve the above-mentioned problems, a portable information processing apparatus according to the present invention includes a hard disk drive using a fixed recording disk for recording information, a removable CD, A disk drive device using a recording disk such as a DVD is fixed to a strong portable information processing device frame.
A weight is arranged at the arm and the tip of the elastic body, and a pendulum set so that the resonance frequency is the same as the maximum rotation frequency of the disk drive device is fixed.

With the above configuration, when a recording disk having a deviated center of gravity is mounted on a disk drive, a large vibration is generated when the disk drive rotates at a high speed and propagates to the frame. When
Since the pendulum resonates and the vibration energy is consumed in this portion, the propagation amount of the vibration energy to the hard disk drive decreases.

An embodiment of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is an exploded perspective view of a portable information processing apparatus according to an embodiment of the present invention, in which a lower housing is removed. In FIG. 1, reference numeral 1 denotes a main body of a portable information processing apparatus, and a hard disk drive 3 using a fixed recording disk and a detachable recording medium on a frame 2 fixed to an upper housing 1a of the main body 1. A CD drive device 4 using a disk is mounted. In the present embodiment, this frame 2 is made of magnesium metal. Reference numeral 5 denotes a pendulum constituted by an arm 5a made of an elastic body and a weight 5b at the tip, and the side opposite to the weight 5b is firmly fixed to the frame 2. The length and elasticity of the arm 5a, the weight of the weight 5b, and the like are set so that the pendulum 5 has the same resonance frequency as the maximum rotation speed of the CD drive device 4.

The lower housing of the main body 1 is attached so as to cover the lower part of the main body 1, but is omitted for convenience of explanation.

The operation of the portable information processing apparatus according to one embodiment of the present invention configured as described above will be described below. When a disk having a deviated center of gravity is mounted on the CD drive 4 and the CD drive 4 is rotated at the maximum speed, the CD drive 4 vibrates at the same frequency as the rotation speed. Vibration energy generated by this vibration is propagated through the frame 2, and at this time, the pendulum 5 whose frequency is set to the resonance frequency resonates and the vibration energy is consumed.
