[0001]
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 Generally, a disc player that reproduces sound by driving an optical disc such as a CD (Compact Disc) or a DVD (Digital Versatile Disc), which is an information recording medium, or a disc device that performs recording and reproduction of information drives the disc to rotate. Therefore, the inside of the device is excited to generate vibration and resonance. In the case of an audio device, it is usually set in an audio rack or the like, but the audio rack is excited by an external factor from the room or a reproduced sound, and the vibration caused by this is transmitted to the inside of the device.
[0003]
By the way, a track in which fine pits are continuously formed is formed on the optical disk, and the pits are read by irradiating the track with laser light of an optical pickup controlled by servo. Accordingly, the optical pickup is driven to follow a minute servo signal accurately, and thus has a structure that is supported so as to move easily in the tracking direction and the focus direction.
[0004]
Due to these structural characteristics, if vibration is transmitted from the drive source of the optical disc or the outside of the device and the optical pickup is shaken even slightly, a pit reading error by the optical pickup, so-called bit loss, occurs. The reproduction characteristics will be deteriorated.
[0005]
Therefore, in general, as a so-called mechanical grounding means for absorbing and blocking vibration, a structure in which an elastic body such as a coil spring or rubber is combined and used as a support leg of a device 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 body that contacts the installation base at one point and supports the housing at three or four locations is effective.
[0006]
As shown in FIG. 8, for example, a conical spike body L1 is formed on a supporting leg main body L fixed to a bottom plate A1 of an audio device A such as a disk player, and one point of the peak is a shelf plate of the audio rack B. It is designed to be grounded on the top surface of B1, and normally, after setting the acoustic device A, the stand base S is arranged between the spike body L1 and the shelf plate B1 as shown in FIGS. .
[0007]
[Problems to be solved by the invention]
However, in the case of this type of audio equipment that seeks to improve the sound reproduction characteristics, the mass of the drive system and the housing increase because of the structure to eliminate vibration and resonance along with the increase in weight accompanying the strengthening of the power supply unit However, the high-end model has an extremely large weight of about 25 kg, and the setting of the acoustic device provided with the spiked body is not easy, and is a large work and requires carefulness.
[0008]
That is, in the setting procedure of the acoustic device A, the device main body is first placed on the provisional setting position of the shelf board B1, and at this time, the shelf board B1 is placed at the peak of the spike body L1. Since it is clear that the surface is damaged, the protective sheet is disposed in anticipation of the position of the spike body L1, and the spike body L1 is disposed on the protective sheet. Thereafter, one side of the device main body is slightly pushed up, the protective sheet is removed, and the stand base S is disposed under the spike body L1.
[0009]
However, it is relatively easy to perform the above-described work in a space where the side and upper part are open, but in a closed space surrounded by the top, bottom, left and right, as in audio rack B shown in FIGS. The dead space is narrowed, which makes setting work extremely difficult. In particular, since the rear surface of the audio rack B is usually close to the wall W in the room, there is no space for setting work, and the workability is extremely low due to the large weight of the audio equipment. there were.
[0010]
However, since the setting of the acoustic equipment is indispensable, it is usually the case that it is housed in the audio rack B by forcible work, and the surface of the shelf board B1 and the surface of the stand base S are covered with spikes. It will be seriously hurt. In addition, when the weight of the device is large, it is a cumbersome work with great effort, and there is a risk of damaging a finger with the tip of the spike body, which requires consideration for safety.
[0011]
The present invention has been made in view of such a conventional problem, and in the structure of this kind of support leg, while taking advantage of the spike body that can efficiently eliminate vibration and resonance, the work is performed when setting the apparatus main body. It is designed to improve safety and safety, so that even a heavy equipment can be easily set in a storage space with little dead space.
