Invention Description (i) [Technical Field to which the Invention belongs] The present invention relates to an optical pickup device for reading and writing information on an optical disc in an optical disc device. Known technology] An optical pickup device is a device mounted in an optical disc device and supported to move freely over the radius of the optical disc so that laser light can enter the information recording surface of the optical disc and read and write information on the information recording surface. The unconventional optical pickup device 50 shown in Fig. 11 is composed of a slider 5 1 assembled on an optical disk device (not shown), and a biaxial actuator 5 2. A 45 degree tilt is followed by a reflection mirror 5 3 fixed to the carriage 5 1 bottom plate portion 5 1 a, and a light emitting and receiving element 5 5 held in a holder 5 4 and an outer cover (c 〇ver ) 5 6. The biaxial actuator 5 2 is composed of: a biaxial base (Base) 5 2 a including a fixed portion, and a sling (suspensi ο nwi ··) 5 2 b, which is flexible and Lens mount (Lens hol) slidably supported on this biaxial base 5 2 a der) 5 2 c, and objective lenses 5 2 d assembled at the front end of the lens holder 5 2 c, and then fixed and fixed to the carriage 5 1 by the adhesive S (refer to FIG. 12). The above lens holder 5 2 c is integrally formed with a yoke (Yoke) 5 2 composed of a magnet (magnet) and a magnetic circuit not shown in the drawing, and a focusing coil (coil) is used for focusing. ) And tracking (coil bobbin) 5 2 f coils between the coils of electricity (Please read the precautions on the back before filling this page) clothing. The size of the paper is applicable to Chinese national standards ( CNS) A4 specification (210X297 mm) -4- 546645 A7 _____ B7 V. Description of the invention (2) The magnetic flux generated between the coils and the magnetic flux generated by the aforementioned magnetic circuit interact with each other to drive the lens holder 5 2 c Focusing direction and chasing direction. On the other hand, the light-receiving element 55 is mainly composed of a light-emitting element that emits laser light and a light-receiving element that receives laser light. The holder 5 4 that holds the light-receiving element 5 5 is an adhesive. T (refer to FIG. 12) is assembled and fixed on the carriage 51. And A circuit board (not shown) with electronic components soldered is assembled on the back of the light-receiving element, and in order to protect the circuit board and block electromagnetic gas, this circuit board is provided with an i cover 56. Furthermore, the aforementioned circuit board is provided The method of transmitting electrical signals to the light-receiving element 55 stably drives the components constituted by the circuit such as the light-emitting element described above. The laser light emitted from the light-emitting element passes through the light-receiving surface 5 5 a of the light-receiving element 5 5 and is refracted by the reflector 5 3 to approximately 90 degrees and enters the objective lens along the optical axis of the objective lens 5 2 d. 5 2 d. Then, the laser light that is continuously concentrated at the objective lens 5 2 d performs a focusing operation on the information recording surface of the optical disc, and performs a chasing action to meet the information recording track of the optical disc. And, the reflected light reflected by the information recording surface of the optical disc, and then refracted through the objective lens 5 2 d and refracted 90 degrees at the reflecting mirror 53, the process of receiving by the light receiving element in the light receiving element 55 can be performed by the optical disc. The reproduction signal 0 is obtained. However, the carriage 5 1 is made of sheet metal, and has a substantially rectangular bottom plate portion 5 1 a. A first side wall portion 5 is arranged facing each other along the long axis direction of the bottom plate portion 5 1 a. 1 b, the second side wall portion 5 1 c. One of the first side wall portions 5 1 b protrudes from the bottom plate portion 5 1 a ', and applies the Chinese National Standard (CNS) A4 specification (210X297 mm) in its paper size. (Please read the note on the back first Please fill in this page again for the matter) Order the Intellectual Property Bureau B of the Ministry of Economic Affairs (printed by the Industrial and Consumer Cooperatives -5- 546645 A 7 B7) V. Description of the invention (3) A gap 5 1 d is formed at the front end. And, with the first, second The side wall portions 5 1 b and 5 1 c are similarly provided along the long axis direction, and the third side wall portions 5 1 e and 5 1 e are mutually integrated with the bottom plate portion 51. The third side wall is integrated with each other. Circular holes 5 1 f and 5 1 f are respectively provided at the portions 5 1 e and 5 1 e. On the one hand, the optical disc device maintains a space formed by the main shaft 5 7 and the auxiliary shaft 5 8 parallel to each other, and inserts the main shaft 5 7 The circular holes 5. 1 f and 5 1 f formed in the carriage 5 1 are slidably supported in the notch groove 51 by the configuration of the auxiliary shaft 5 8 so that the optical pickup device can slide along each axis. The ground is supported. [Problems to be Solved by the Invention] However, the conventional optical pickup device constructed in this manner has the following problems. Yes, the conventional carriage 5 1 is made of 3 low-cost sheet metal..., As shown in FIG. 12, compared with the circular hole 5 1 f, 5 1 f is engaged with the main shaft 5 7. The center of gravity A of the triangle ABC constituted by the part A 'B of the groove A and the section C where the notch groove 5 1 d is engaged with the auxiliary shaft 5 8, and the center of gravity of the optical pickup device 50 is at the substantially rectangular bottom plate portion 5 1 a The central part G /, for example, when the optical disc device is subjected to an impact during transportation, the impact will move at the center of gravity G > and a torque (Torque) will be generated due to the deviation from the center of gravity g of the triangle abc. The second side wall portion 5 1 c side, in particular the end portion 5 1 g, undergoes a large amount of deformation. As a result, the subsequently fixed biaxial actuator 5 2 'reflector 5 3 or the holder 5 4 is peeled off and the paper is peeled off. Standards are applicable to China National Standard (CNS) A4 specifications (210 × 297 mm). Clothing — (Please read the precautions on the back before filling out this page) Order printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, M Industrial Consumer Cooperatives. Description of the Invention (4) (Please read the precautions on the back before filling in this page) The strength decreases, or the above-mentioned component position is caused Offset, the carriage 51 is unable to read and write due to the plastic deformation of the optical axis, and the optical pickup device has these problems that cause performance degradation. In order to prevent the above deformation, the second side wall portion of the carriage 51 5 1 c The front end extending at the end portion is formed with the same notch groove 5 1 d formed at the front end of the first side wall portion 5 1 d. The notch groove 5 1 d not shown in the figure is considered to adopt A, B, and C And the four-point support method of the carriage 51, but in this case, even if the main shaft 5 7 and the auxiliary shaft 5 8 are kept in parallel with good accuracy, the round holes 5 1 f, 5 1 f and 2 notch grooves When the position accuracy of 5 1 d and 5 1 d respectively is insufficient, the carriage 5 1 located between each axis 5 7 and 5 8 cannot operate smoothly, that is, the optical disc device itself needs to adopt a high-precision design. This causes a problem of a substantial increase in production costs.
