[0002]
[Prior art]
2. Description of the Related Art As a carriage used in a conventional optical pickup device, an aluminum die-cast carriage formed by using a metal mold made of a metal such as an aluminum alloy is often used. In this aluminum die-cast carriage, an optical member is placed at a predetermined position on the carriage, and is fixedly adhered using an adhesive or the like.
[0003]
On the other hand, use of a sheet metal carriage as a carriage for an optical pickup device has been studied as an alternative to aluminum die casting or the like in order to reduce costs.
[0004]
FIG. 6 is a perspective view showing a conventional optical pickup device 50, which is formed by a carriage 51 made of sheet metal.
[0005]
The carriage 51 is bent with respect to a bottom surface 51d to form side surfaces 51a, 51b, and 51c. At one end of each of the side surfaces 51a, 51b, an insertion hole 52, 52 as a guide portion is formed, and a guide shaft 55 is inserted through the insertion hole 52, 52. Further, at the other end of the side surfaces 51a and 51b, guide portions 53a and 53b whose front ends are cut out in a U-shape are formed. Further, on the bottom surface 51d of the carriage 51, mounting pieces 54a and 54b are formed by being bent inward. The attachment pieces 54a and 54b are cut and raised in a direction orthogonal to the bottom surface 51d so as to face each other. The optical member 60 is disposed between the mounting pieces 54a and 54b with a gap provided between the mounting pieces 54a and 54b. In this case, the optical member 60 is positioned and fixed on a dedicated jig 61 and then positioned between the mounting pieces 54a and 54b of the carriage 51. Then, a gap is filled between the mounting pieces 54a and 54b with an adhesive, and the optical member 60 is fixed to the carriage 51.
[0006]
[Problems to be solved by the invention]
However, the conventional optical pickup device using the aluminum die-cast carriage has a problem that the unit price of the carriage is high and the cost is high. In addition, since the positioning accuracy of the optical member must be guaranteed only by the accuracy of the carriage alone, there is a great effect when the accuracy of the carriage varies, and it is difficult to completely guarantee the accuracy for all carriages. Was. Further, since it is necessary to bond the optical components one by one, there has been a problem that the number of steps in manufacturing increases.
[0007]
Therefore, a low-cost sheet metal carriage has been proposed in place of the above-described aluminum die-cast carriage. However, the unit price of the carriage formed of sheet metal can be reduced in cost compared to a carriage such as an aluminum die-cast, but when the optical member is positioned on the carriage, the side surface of the jig 61 is positioned inside the carriage. Since the optical member and the carriage are positioned by being pressed against the side surface 51a, there is a possibility that the relative position between the optical member and the carriage deviates from a predetermined position. That is, since the side surface 51a is formed by bending, the jig 61 may be bent when the jig 61 is pressed against the side surface 51a. As a result, the gap between the optical member 60 and each of the mounting pieces 54a and 54b is formed. Are not equal to each other, a difference occurs in the filling amount when the gap is filled with the adhesive, and the optical member 60 and the mounting pieces 54a, 54a, due to the contraction or expansion effect of the adhesive itself when the adhesive is cured. Therefore, the distance between the first and the second 54b was not uniform, and it was difficult to perform accurate positioning.
[0008]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and can reduce the cost. Furthermore, the optical members are evenly arranged on the respective mounting pieces, and the adhesive shrinks and expands at the time of bonding and fixing. It is an object of the present invention to provide an optical pickup device that can suppress the influence of the effect.
[0009]
It is another object of the present invention to provide a method of manufacturing an optical pickup device in which an optical member can be evenly arranged between the mounting pieces when positioning the optical member on the mounting piece.
[0010]
[Means for Solving the Problems]
The present invention relates to an optical pickup device having a carriage having a guide portion for moving the disk in a scanning direction and a mounting surface forming a pair, and an optical member adhesively fixed between the mounting surfaces.
The carriage has a positioning receiving portion for positioning the carriage in a direction along the guide portion, and the position of the optical member is determined based on the guide portion and the positioning receiving portion. It is characterized by being fixedly adhered between the mounting surfaces.
[0011]
With the above-described means, since the carriage is not positioned and positioned with reference to the side surface of the bent carriage, no displacement occurs due to the bending of the side surface.
[0012]
Further, according to the present invention, a gap between the optical member and each mounting surface is substantially equal, and the optical member and the mounting surface are fixed by an adhesive filled in the gap portion. preferable.
[0013]
By the above means, the filling amount (volume) when the gap is filled with the adhesive can be made the same, and when the adhesive is cured, the optical member and each of the optical members due to a contraction effect or an expansion effect due to a temperature change or the like of the adhesive. It is possible to prevent the gap between the optical member and the mounting surface from becoming non-uniform and the optical member from being positioned and fixed to a position shifted from a predetermined position with respect to the carriage.
[0014]
In the present invention, it is preferable that the optical member is positioned such that an optical axis of the optical member coincides with a line orthogonal to a guiding direction of the guiding portion and passing through the positioning receiving portion.
[0015]
This ensures that the optical members are arranged with a uniform gap between the respective mounting surfaces.
[0016]
In the present invention, it is preferable that the positioning receiving portion is cut out in a V-shape.
[0017]
The positioning receiving portion is not limited to the V-shaped one, but may be an arc-shaped one, or may be a protruded one instead of a notched one. It may be formed at three places.
[0018]
Further, in the present invention, it is preferable that the carriage is made of sheet metal, and the mounting surface is formed on a facing surface of a pair of mounting pieces bent from the carriage.
[0019]
According to the above-mentioned means, it is not necessary to use a carriage made of aluminum die-casting which is expensive in cost, and cost can be reduced. However, the carriage according to the present invention can be embodied even if it is not formed of a sheet metal.
[0020]
The present invention also provides a method of manufacturing an optical pickup device for positioning and fixing an optical member between the mounting surfaces of a carriage having a pair of mounting surfaces.
The carriage is provided with a guide portion for moving the disk in the scanning direction and a positioning receiving portion for positioning the carriage in a direction along the guide portion. On the fixture, the carriage is positioned with reference to the guide portion and the positioning receiving portion, and at this time, the optical member positioned on the jig is located between the mounting surfaces formed on the carriage, The optical member is bonded and fixed between the mounting surfaces.
[0021]
By the above means, the positioning accuracy of the optical member can be assured by the jig, so that the accuracy of the carriage can be made rough to some extent, and even if the carriage is made of sheet metal that cannot guarantee high positioning accuracy, The members can be positioned with high accuracy.
[0022]
Further, according to the present invention, the guide portion formed in the carriage is a guide hole, and a shaft inserted in the guide hole is pressed against the jig, and a pressing member provided in the jig and the positioning receiving portion are formed. It is preferable that the carriage is positioned on the jig by fitting.
[0023]
For example, by providing a biasing member that presses and fits the positioning receiving portion on the pressing member side, the shaft is pressed against the jig simultaneously when the pressing member and the positioning receiving portion are fitted. The positioning is assured.
[0024]
Further, in the present invention, it is preferable that the optical axis of the optical member is positioned in a direction orthogonal to a guiding direction of the guiding portion and on a line passing through the positioning receiving portion.
[0025]
As described above, the optical members are reliably arranged with a uniform gap between the respective mounting surfaces.
[0026]
Further, in the present invention, it is preferable that a gap between the optical member and each mounting surface is made substantially uniform, and the optical member and the mounting surface are fixed with an adhesive filled in the gap portion.
[0027]
By the above means, the filling amount (volume) when the adhesive is filled in the gap portion can be made the same, whereby the shrinkage or expansion due to the temperature change of the adhesive when the adhesive is cured can be reduced. For this reason, the gap between the optical member and each mounting surface becomes non-uniform, thereby preventing the optical axis of the optical member from being shifted from a predetermined position and fixed.
[0028]
