In particular, the present invention relates to an assembly structure for incorporating the flexible printed board into a zoom lens barrel or the like.

There are two ways to use it: one is to mount circuit elements on it and use it as a circuit board, and the other is to simply use it as wiring. When using FPC as wiring, conventionally, a flexible printed board was fixed to a single device surface, or
Alternatively, the attachment method used was to stretch it between members that do not move relative to each other, but recently it has also been used to supply power and signal transmission to moving parts by stretching it between multiple members that move relative to each other. .

れる恐れもない。When installing FPC between members that move relative to each other,
It is necessary to prevent the FPC from sagging or sagging when the members move relative to each other and the distance between the members changes.
A mounting method is used in which a U-turn portion is formed between two mounting positions of a PC. When the distance between the two mounting positions changes (that is, when the distance between the two members changes), the U-turn portion moves parallel to the direction of relative movement of the members in response to the change. Even if relative movement occurs between the two, the FPC will not sag or sag,
There is no fear that the movement of the member will be hindered due to hanging or sagging of the PC.

いる。FPCs bent into a U shape (i.e., forming a U-turn between two fixed points) are used as internal power feed lines for devices with built-in movable parts, such as zoom lenses for cameras. In the lens barrel, it is used as a power supply line and a signal transmission line between the movable barrel and the fixed barrel.
