摘要： A frame 7 and a clamper support 15 are aligned flat and formed integrally with each other through connectors 20, whereby the flame 7 and the clamper support 15 can be formed using a common forming mold. If the clamper support 15 is arranged within an opening 7C, then the forming mold can be made small in size and light in weight, a load applied to a driver for the forming mold can be reduced, and a forming speed can be accelerated. Productivity can be thereby improved. Further, while an upper portion of the frame 7 is opened, such constituent elements as a turntable 4, a pickup lens 5, a feed mechanism 8 of the pickup lens 5 can be attached to the frame 7. Assembly performance can be thereby improved.

摘要： The invention provides a disk reproducing device capable of automatically detecting dirt on a lens without using any additional members. A pickup unit 5 reads a video signal of a storage medium 2, comparison/judgment means 9a compares an attenuation ratio of an RF signal B amplified by an RF amplifier section 8 to a standard RF signal A stored in a storage section 12 with a threshold P likewise stored in the storage section 12 and judges that there is dirt on a pickup lens 51 when the comparison value falls below the threshold P, and a display section 11 displays alarm message data 122 stored in the storage section 12 superimposed on images being reproduced, and it is possible to thereby automatically detect dirt on the pickup lens 51 and report it to the user.
