Title: Lens unit
Inventor: SASAKI RYUTA
IPC: G02B7/04
Filed: 2001-03-08
Abstract: PROBLEM TO BE SOLVED: To increase the component strength of a lens unit without making the lens unit large-sized by making a top (a bell-shaped piece), constituting a cam follower, of metal. SOLUTION: The cam follower 32 of a moving cylinder 22 of the lens unit 2 is constituted by fitting the top (bell-shaped piece) 54 to a boss part 23 molded integrally with the moving cylinder 22 and fitting a guide plate 55 to the top 54. The top 54 is fitted in a cam groove 24b of a fixed cylinder and the guide plate 55 is fitted in a rectilinear groove 25c of a cam cylinder 26. The top 54 is made of metal such as aluminum, iron and stainless steel and has sufficient strength as compared with a plastic one. Thus, the top 54 is made of metal and then the diameter d1 of the boss part 23 can be made large by making the top 54 thin. Namely, while the existent diameter of the cam follower 32 is maintained, the diameter d1 of the boss part can be made larger than a conventional diameter d2, so the strength of the boss part 23 increases.

A resonance circuit 230 has a center resonance frequency within a range of a resonance frequency including the repetition rate of the pulse generator.  The resonance circuit generates the first signal having a voltage higher than the supply voltage, and processing thereafter is facilitated by making a current value of the induced current sufficiently large.
