Description of the Invention (i) The present invention relates to a kind of housing that includes a first component and a second component that can be arranged relative to each other by a spacer. Such as a disc-shaped recording medium drive device 'It is used to take out information recorded in a disc-shaped recording medium such as a CD or CD. The disc-shaped recording medium is a functional machine for writing information. It includes a box and- It can be used as a bracket and other components that can slide freely on the box. This box system is installed in electronic equipment such as notebook computers. The bracket part is used to take out and put the disc-shaped recording medium from the case. The bracket part has a rotating part, which is a lower part of the upper part of the component, and a lower part of the component, which is arranged between the casings, and an optical pickup section. The upper case includes a protrusion that protrudes toward the lower case and has a screw hole. The lower case has a through hole through which a screw can pass. The upper case and the lower case are fixed to each other by screws that are screwed to the protruding portions through the through holes. The rotary table can support a disc-shaped recording medium and be driven in rotation. The pickup unit is used to retrieve information recorded on the disc-shaped recording medium. The aforementioned rotary table and pickup unit can be supported between the upper case and the lower case by an elastic body. A spacer having a relatively thin thickness is arranged between the lower case and the elastic body for various reasons such as the mounting accuracy of the two cases. The spacer is opened / formed into a ring shape, and the screws for fixing the two shells to each other are used to pass through the center of the spacer, and then positioned at an appropriate position, and is arranged on the elastic body and the lower shell. between.

A7 V. Description of the invention (2) B7: The elastic body is placed in the pre-position of the human body X, and at the same time, a rotating table s is placed / and then the spacer is placed on the elastic body. Then, after determining the position of the lower case X body, the aforementioned screws are screwed into the screw holes, and the two cases are fixed to each other to complete the assembly. "However, the lower case and the spacer are formed to have a thin thickness at the same time, so it is difficult to position the spacer at an appropriate position by the aforementioned protrusions, etc. Therefore, if the lower case is to be positioned during the aforementioned assembly operation, When it is on the upper case, the lower case will be connected with the spacer to make the spacer open. At this time, because the operator cannot confirm the state of the displacement of the spacer, the drive device for the disc-shaped recording medium after assembly When regenerating a disc-shaped recording medium, "it is possible that the expected information cannot be reproduced with certainty." Also, an operator who performs the assembly operation is to move the lower case without displacing the spacer. When the upper case is fixed, 'the special care must be taken when positioning the lower case. Therefore, reducing the efficiency of the aforementioned assembly operation and increasing the number of assembly operations to go online' tends to increase the cost of the disk-shaped recording medium drive device body. 0 Yes Therefore, the purpose of the present invention is to provide a kind of carcass, which can be confirmed that when the components are fixed to each other, it can be confirmed that the spacers arranged in the lotus root and the temples have been placed in an appropriate position.

In this way, the housings 22 and 23 of this embodiment can be fixed to each other by screws 24 and screw holes. + When the casing i according to this embodiment is fixed to the shells 22 and 23, the edge portion of the spacer 46 is exposed to the outside through the exposure hole 33. Therefore, when the housings 22 and 23 are fixed to each other, the edges of the spacer 46 exposed through the respective exposure holes can be checked to determine whether the spacer 46 is located at an appropriate position. Also, when the spacer 46 is in position, the exposure holes 33 are each constructed so that the area of the edge of the spacer 46 is exposed to a degree that is approximately the same. Therefore, the exposure of the spacer 46 is confirmed by each of the exposure holes 33. To the extent that the edges are exposed, it can be confirmed whether or not the spacer 46 is already in place. For example, as shown in Fig. 3, the state of the spacer M that is not in an appropriate position can be easily grasped by the state where the area of the edge of the spacer 露出 exposed by each of the exposure holes 33 is different in degree '. The spacer 46 is formed into a circular shape, and the exposed hole 33 is arranged at a position with equal clearances in the circumferential direction around the through-hole 32, that is, the screw 24 and the screw hole 28. Therefore, the spacer is located appropriately At the time of the position, it is possible to further confirm that the area of the edge portion of the spacer exposed by each of the exposure holes, that is, the state of the same degree. Therefore, confirming the degree of bareness of the edge of the spacer by each exposed hole can further confirm whether the spacer is already in an appropriate position. In addition, the spacer 46 smoothes the surface and reduces the coefficient of friction with the lower case.

I 1 This paper ruler-Description of the invention (1ό) The effect of the invention is described above. According to the invention of the first aspect, the spacer is located on the second wall where the proper ::: exit piece is formed. This component: Road-Road exit hole. So ‘in the first! When the member and the second member are fixed to each other, the edges of the exposed spacers are confirmed by the respective exposure holes, so that it can be confirmed whether the spacers are positioned at appropriate positions. According to the invention of the second aspect, each of the exposed holes can be formed for the spacer position: suitable: position, the state where the edge of the spacer is exposed to approximately the same degree, and the exposed holes are used to confirm the spacer's To the extent that the edge is exposed, you can confirm whether the spacer is already in place. According to the invention of the third aspect, the spacer is formed in a ring shape, and the exposed holes are arranged at positions at equal intervals in the circumferential direction with the fixing device as the center. Therefore, when the spacer is in an appropriate position, it can be The degree of the edge of the spacer exposed by each of the exposed holes is further made uniform. Therefore, the extent to which the edge of the spacer is exposed through these exposed holes' can be used to confirm whether the spacer is already in an appropriate position. According to the invention of the fourth aspect, an elastic body is provided to support the vibration source between the first and second members, and at least one of the aforementioned first and second members and the aforementioned elastic body are arranged. There is a spacer with a small coefficient of friction. Therefore, 'the vibration generated by the vibration source' causes the spacer and the member to slide against each other ', making it difficult for the vibration generated by the vibration source to be transmitted to the member. According to the invention of the fifth aspect, it is attached to the second wall of the second member for the spacer to be located at an appropriate position, and 480476 A7 is formed to expose the edge of the spacer.

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Therefore, you can know the extent of the exposed edge of the spacer through the exit holes of the current π Lingtian Guzi, so that you can confirm whether the spacer is in an appropriate position. ----------------- r --- Order --------- line < Please read the notes on the back before filling this page) -20 · This Paper size applies to China National Standard (CNS) A4 (210 X 297 mm)
