板の装着装置に関するものである。[Detailed description of the invention] (Field of industrial application) The present invention relates to a printed board mounting device, and in particular, the present invention relates to a mounting device for a printed board, in particular, for mounting a flexible printed board in a narrow space formed by a fixed cylinder and a movable cylinder in a lens barrel, etc. This invention relates to a printed board mounting device that electrically connects a fixed cylinder and a movable cylinder so that when the movable cylinder is moved, the printed board can move smoothly along with the movable cylinder. .
（従来の技術）
従来よりフレキシブル性のプリント板は薄くか

種の機器に用いられている。(Prior art) Flexible printed circuit boards have traditionally been thin and highly flexible, and can be bent at will, making it possible to efficiently store them in narrow spaces within devices, such as camera bodies, etc. Used in various devices such as lens barrels.
このうちレンズ鏡筒にプリント板を装着する場

１とズーム操作やフオーカス操作を行う可動筒６
２とで挟まれた空間内に装着する場合が多い。 Among these, when attaching a printed board to the lens barrel, for example, Fig. 6 and Fig. 7, which is a cross section of the main part.
Fixed tube 6 connected to the camera body side as shown in the figure
1 and a movable barrel 6 for zooming and focusing operations.
It is often installed in the space between 2 and 2.

いる。 When electrical connections are made from the fixed tube 61 to the movable tube 62, for example for transmitting and receiving zoom signals, when the connection tubes are separated from each other, a flexible printed board 63 is used as shown in FIG. It is attached so that two bent portions 64 and 65 are formed. When the movable tube 62 is moved, the bent portions 64 and 65 of the printed board are displaced along with the movement of the movable tube 62.

信頼性を損なう場合があつた。そしてこの２つの
折り曲げ部があつてもプリント板をスムーズに変
位させる為には可動筒６２の径が増大してくる傾
向があつた。 In this manner, conventionally, when connecting the ends of a printed board to separate positions, two bent portions 64 and 65 were formed at the intermediate position, and the printed board was mounted in a narrow space. Therefore, the space (radial gap) between the fixed cylinder 61 and the movable cylinder 62 basically consists of two bent parts 64,
Since only the dimensions of the curved portion (A+B) of 65 are required, a problem arises in that the diameter of the lens barrel inevitably becomes large. Moreover, if the space between the fixed cylinder 61 and the movable cylinder 62 is set narrow, one bent part 64 will be connected to the printed board 6, as shown in FIG. 8b.
It touches the base of 3. Therefore, the movable tube 62
When the movable cylinder moves, the base surface of the printed board 63 is rubbed improperly by the surface of the bent part 64, causing damage to the coverlay, and unreasonable force is applied to the printed board as the movable cylinder moves. In some cases, the printed board may not be displaced smoothly, or a portion of the printed board may be suddenly displaced, impairing the electrical reliability of the printed board. Even with these two bent portions, the diameter of the movable cylinder 62 tends to increase in order to smoothly displace the printed board.
