In a high-frequency module mounting structure according to the present invention, a circuit board includes a reinforcing electrode on the lower surface thereof for increasing a mounting strength of the first and second electrode groups in a state of being in close proximity, a motherboard includes a reinforcing lands corresponding to the reinforcing electrodes in a state of being in close proximity to the lands, and the electrodes and the lands, and the reinforcing electrodes and the reinforcing lands are soldered. Therefore, soldering of the high-frequency module with respect to the motherboard is enhanced, and thus a reliable high-frequency module mounting structure is provided.

High frequency module mounting structure in which solder is prevented from peeling

A first and second rotary members are supported on a holder 3 secured to a main chassis of disk drive apparatus. The first rotary member includes a detecting portion. The second rotary member includes a contact portion that moves in and out of the insertion path of a disk cartridge to be inserted into the holder. When the disk cartridge is being inserted, an opening-and-closing pin opens the shutter of the disk. Through the detecting portion, the opening shutter rotates the first rotary member, which then rotates the second rotary member to thereby move the contact portion of the second rotary member out of the insertion path of the disk cartridge, allowing the disk cartridge to be inserted. If the shutter fails to open when the disk cartridge is being inserted, the contact portion of the second rotary member will remain in the insertion path and block the insertion of the disk cartridge.
