Description

The load bearing seat device of CD-ROM drive reading unit

Technical field

The utility model provides a kind of load bearing seat device of CD-ROM drive reading unit, it makes the load bearing seat on this device not change the pinion stand size and save under the situation in space, can increase engaged wheel again, make the reading unit on the load bearing seat more steady in moving process, thereby make the picture that reads the back conveying more clear.

Background technology

With reference to shown in Figure 1, traditional CD-ROM drive has a load bearing seat 1A, and rotating disk 2A and reading unit 3A are arranged on load bearing seat 1A.Fig. 1 is the bottom schematic view of load bearing seat 1A, wherein has a fluting 11A on the load bearing seat 1A.This fluting comprises a circular trough 111A and straight slot 112A, is used to install rotating disk 2A and reading unit 3A.Be pivoted with a support 31A on straight slot 112A, this support 31A is provided with reading unit 3A, is used for reading the information on the CD.Then be fixed with a rotating disk 2A on circular trough 111A, rotating disk 2A is fixed on the location-plate 21A.Reading unit 3A is driven by a gear train 4A.Gear train 4A includes a gear set 42A.Gear set 42A is installed on the pinion stand 41A.Gear set 42A is made of a driving gear 421A and follower gear 422A.Also be provided with a motor 43A in addition.The output shaft of motor 43A and driving gear 421A pivotally link together.Also be provided with a lead screw 44A in addition, the end of lead screw 44A pivotally is connected with follower gear 422A, and the other end then is connected with pair of guide rods 45A.The support 31A of reading unit 3A is enclosed within on the guide rod 45A.

Therefore, can rotate with motor 43A drive gear set 42A.The follower gear 422A of gear set 42A drives lead screw 44A again and rotates, and drives guide rod 45A and rotate, and support 31A is moved on guide rod 45A, thereby makes the reading unit 3A on the support 31A read information in the CD by fluting 11A place.

Gear set 42A among the load bearing seat 1A of above-mentioned so traditional CD-ROM drive rotates because only drive lead screw 44A, guide rod 45A by two gear 421A, 422A, so the reduction gear ratio when gear set 42A is rotated is too small, make the spacing of support 31A when displacement excessive, the unstable and slack situation of poor quality, picture that causes reading unit 3A to read produces.And, because be subjected to the space constraint of CD-ROM drive, under the situation that can't change pinion stand 41A size, can't increase gear more in addition.In addition, the rotating disk 2A on the CD-ROM drive is fixed on the load bearing seat 1A by location-plate 21A.If rotating disk 2A is not up to the standard on being locked in location-plate 21A the time, then needs whole rotating disk 2A disassembled and reinstall very inconvenience in assembling like this.

In view of the shortcoming of above-mentioned traditional CD-ROM drive, inventor of the present utility model is according to being engaged in the sector experience for many years, and in line with excelsior spirit, the active research improvement is so there is the generation of " the load bearing seat device of CD-ROM drive reading unit " of the present utility model.
