2. Background Art Digital audio discs (hereinafter
A DAD player records music, voice and other information in the form of fine pits at high density on a small, thin compact disk with a diameter of about 12 cm and a thickness of about 1.2 mm using the PCM (Pulse Code Modulation) method, and reads and plays back this information using an optical pickup that uses a laser beam. In such an optical pickup, it is necessary to set the mounting angle and mounting height of the pickup head within a certain range in advance so that there is no positional deviation or focus deviation with respect to the information pit that the beam spot of the laser light irradiated from the pickup head is trying to resolve, and so that this information pit is always correctly positioned at a predetermined position on the lens axis of the optical system. Conventionally, this head mounting adjustment mechanism has mostly been based on an adjustment screw like the asymmetric adjustment mechanism applied to the head of a tape recorder. However, this is only for adjustment in one direction,
This cannot be applied to devices that require angle adjustment in two perpendicular directions, such as the pickup of a DAD player. In this case, three adjustment screws are used to support the pickup from three directions, but this means that when one adjustment screw is turned, the entire pickup inevitably changes angle in both perpendicular directions, making it impossible to adjust the angle of only one side alone.
Even if it is necessary to adjust the angle in only one direction, it is necessary to use all the adjustment screws to adjust in both directions at the same time, and the adjustment must be done by turning each adjustment screw several times in small increments. As a result, the operation is very tedious and time-consuming, and since the pickup is supported by the adjustment screws simply at points, it may become misaligned after adjustment, and there is a problem of poor stability. Furthermore, if the pickup is set to a specified height and supported, the operation of turning each adjustment screw becomes even more complicated, and the assembly and adjustment of the pickup becomes very troublesome.

First, assume that in the unadjusted state shown in FIGS. 1 and 2, the table 7 to be adjusted is on the side of the adjustment base 1 from the reference position shown by the solid line A, and therefore the head of the pick-up is separated from the disk surface. . in this case,
The first and second adjustment screws 2 and 3 are rotated to move the adjusted base 7 forward to a predetermined reference position A, and adjust the adjusted base 7 so that it is parallel to the base plate 1. Further, if the table 7 to be adjusted is separated from the adjustment base 1 from the reference position indicated by the dotted line B and the head of the pick-up approaches the disk surface side, it is rotated in the opposite direction to the above and retreated to the reference position B. After each adjustment, the adjusting screws 2 and 3 are set on the base plate 1 using fixing nuts or the like (not shown). Next, when adjusting the angle of the table 7 to be adjusted in the X direction, the adjusting drum 5 is moved from the position shown in FIG.
When rotated by the rotation operation of the rotation device 6, the
As shown in FIG. 2, the top surface of the adjustment drum 5 is rotated to a position along the X direction, and along with this, the protrusion 9 is moved along the top surface of the adjustment drum 5 at a distance corresponding to the height of the slope. The protrusion 8 is moved up and down by a predetermined amount to the lowermost position and to the uppermost position. the result,
As shown in FIG. 3a, the table 7 to be adjusted is inclined to one side in the X direction with respect to the base plate 1 at an angle corresponding to the angle of inclination of the upper surface of the adjustment drum 5, and the angle is adjusted to the one side. Ru. Conversely, when the adjusting drum 5 is rotated at an angle of, for example, 90 degrees in the direction indicated by the arrow D shown in FIG. is at the uppermost position in the inclination direction along its upper surface, and the protrusion 8
is moved up and down by a predetermined amount to its lowest position, and the adjusted table 7 is tilted to the other side in the X direction with respect to the base plate 1 at an angle corresponding to the upper surface inclination angle of the adjustment drum 5, thereby performing angle adjustment. At this time, the protrusions 8 and 9 are on the diameter passing through the center axis of the adjustment drum 5, and the protrusion 10 is supported on the adjustment screw 3 in a pop-shaped, ie, point contact state, so that the table 7 to be adjusted is It only tilts in the X direction using the center axis of the adjustment drum 5 and the tip of the projection 10 as a fulcrum,
It is held parallel to the base plate 1 as shown in FIG. 3b without being angularly displaced in the Y direction. Therefore, the angle adjustment of the adjusted table 7 in the X direction is performed completely independently of the Y direction. In this case, when the adjusting drum 5 is rotated at an angle of 90 degrees in the direction of the arrow C, the angle of the adjusted table 7 is adjusted to one side at the maximum tilt angle, and when it is rotated at an angle of 90 degrees in the direction of the arrow D. When the angle is adjusted to the maximum tilt angle to the other side. Then, by selectively setting and rotating the adjusting drum 5 at an arbitrary angle within the range of plus 90 degrees to one side and minus 90 degrees to the other side, the table 7 to be adjusted is adjusted within the range of the above-mentioned inclination angle. The angle is adjusted to one side or the other side in the X direction with respect to the base plate 1 at a desired angle.

On the other hand, when adjusting the angle of the adjustable base 7 in the Y direction from the position shown in FIG. Moves up and down depending on pitch. As a result, the adjusted table 7 becomes as shown in FIG. 4a.
The right side in the figure tilts downward or upward using the protrusions 8 and 9 as fulcrums. At this time, the adjusted base 7 is supported by the protrusion 10 in point contact with the adjusting screw 3, and the protrusions 8 and 9 are supported on the diameter of the adjusting drum 5 along the X direction. X as shown in figure b
It will not be angularly displaced in the direction, but will be tilted only in the Y direction using the tip contact line of the protrusions 8 and 9 as a fulcrum,
Therefore, the angle adjustment of the adjusted table 7 in the Y direction is performed completely independently of the X direction.

According to this example, the height of the adjusted base 7 is adjusted because the adjusted base 7 is always biased toward the base plate 1 with a constant biasing pressure by the springs 17 inserted in the mounting screws 13 and 14. When adjusting or adjusting the angle, it can be done smoothly without rattling, floating, or positional deviation.
