BACKGROUND OF THE INVENTION
The present invention relates to a support device suitable for use in a housing of an audio device such as an audio system or various information devices.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, for example, a disc player that reproduces sound by driving an optical disc, which is abbreviated as a CD (compact disc) or a DVD (digital versatile disc), has a power source for rotating the disc. The inside of the device is excited to generate vibration and resonance. Such an acoustic device is generally set on an installation table such as an audio rack. However, the installation table is excited by an external factor from the room or a reproduced sound, and vibration is transmitted to the inside of the device.
[0003]
By the way, a track in which fine pits are continuous is formed on the optical disc, and the pits are read by irradiating the track with laser light of an optical pickup controlled by servo. Therefore, the optical pickup is driven so as to accurately follow a minute servo signal. Therefore, the optical pickup has a structure that is supported so as to easily move in the tracking direction and the focus direction.
[0004]
Due to these structural features, when vibration is transmitted from the drive source of the optical disk or the outside of the device and the optical pickup swings even a little, pit reading error due to the optical pickup, so-called bit loss, occurs and the sound reproduction characteristics deteriorate. It becomes.
[0005]
Therefore, usually, as a so-called mechanical grounding means for absorbing and blocking vibration, a configuration in which an elastic body such as a coil spring or rubber is combined and used as a support leg of the equipment housing is generally adopted. In this case, the support legs are attached to the bottom plate of the equipment housing with screws. Therefore, the mounting strength of the support leg is limited to the rigidity of the screw, and a sufficient mechanical ground cannot be obtained. As a means for solving such a problem, it has been confirmed that what is called a spike leg and contacts the installation base at one point and supports the housing at three or four places is effective.
[0006]
As shown in FIG. 5, for example, a pedestal L1 of a supporting leg main body L1 fixed to an acoustic device A such as a disc player is formed in a conical spike shape, and one point of the peak is formed on the top plate surface of the installation base B. In general, the stand base S is interposed between the pedestal L1 and the installation base after setting the acoustic device. Further, in order to make vibration absorption and blocking more effective, as shown in FIG. 6, the sharpness of the pedestal L2 tends to be increased.
[0007]
[Problems to be solved by the invention]
By the way, in the case of this type of acoustic equipment that seeks to improve the sound reproduction characteristics, the structure for eliminating vibration and resonance increases the mass of the drive system and the housing, and the high-end model has an extremely large value of around 25 kg. Setting the weight on the installation base of the audio equipment with spiked legs is not easy and requires caution.
[0008]
In other words, the procedure for setting such an audio device is to first place the device main body at a temporary setting position on the installation table. At this time, the spike leg may damage the top plate surface of the installation table. Since it is clear, the protective sheet is placed with the position of the spike leg predicted, and the spike leg is grounded on the protective sheet. After that, one side of the device body is slightly pushed up, the protective sheet is removed, and a stand base is interposed under the spike leg.
[0009]
Such a setting operation is a laborious and cumbersome operation if the weight of the device is large, and requires careful attention. Further, when the spike leg is sharp as shown in FIG. 6, there is a risk of damaging the fingers, which requires safety considerations.
[0010]
The present invention has been made in view of such a conventional problem, and while making use of the advantages of a conventional spike leg, it improves workability when setting the apparatus body on the installation base, and damages the installation base. In addition, the safety of the fingers during work will be ensured. And it aims at enabling it to attach a supporting leg apparatus to an apparatus housing | casing with a highly rigid structure, and to eliminate a vibration and resonance more efficiently.
[0011]
