変し、信号を遅延させる連続可変遅延器に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention changes the length of the transmission line by changing the length of the conductor, changes the phase of the signal, and delays the signal. The present invention relates to a continuously variable delay device.
［従来の技術］ 従来の連続可変遅延器を第４図（ａ），（ｂ）に示す。

可変して信号を遅延させることができる。[Prior Art] A conventional continuously variable delay device is shown in FIGS. 4 (a) and 4 (b).
The continuous variable delay device 20 shown in FIG. 4 (a) includes input / output connectors 21 and 22, fixed transmission lines 23 and 24 connected to the input / output connectors 21 and 22, and the transmission lines 23 and 24. It is composed of a variable transmission line 25, and the transmission lines 23, 24, 25 are pipe-shaped. The transmission line 25 is partly a moving plate
26 is fixed. The moving plate 26 is movable in both directions of the arrow in the figure by the drive unit 27. Therefore, by moving the transmission line 25, the entire length of the transmission lines 23, 24, 25 can be changed. The signal can be delayed by varying the phase of the signal.
また第４図（ｂ）に示す連続可変遅延器30は、遅延量を
増加させるために、伝送ライン23,24,25,28を多重に構
成している。Further, the continuously variable delay device 30 shown in FIG. 4 (b) has multiple transmission lines 23, 24, 25 and 28 in order to increase the delay amount.
［発明が解決しようとする問題点］ 従来の連続可変遅延器20において一方の伝送ライン25

が重くなる問題点がある。[Problems to be Solved by the Invention] One transmission line 25 in the conventional continuously variable delay device 20
Are formed in a U-shaped integrated structure, and the axial dimensions of these lines and the parallelism thereof are precise in the transmission line 23 and one end 25a of the transmission line 25, and in the transmission line 24 and the other end 25b portion of the transmission line 25. If not taken into consideration, there is a problem that the sliding of the transmission line 25 becomes heavy.
また、同様に一方の伝送ライン25がＵ字形である場合
に、全体の伝送ラインの長さを長くとるには、伝送ライ
ン23,24,25を長く設定しなければならなず、縦、横いず
れか一方向に長い連続可変遅延器となり、さらに摺動を
重くしないために、さらに精密度を高くしなければなら

延量を増加させるには、第４図（ｂ）に示す如く、伝送
ラインを多重にすれば良いが、Ｕ字形の伝送ラインが多
くなり固定の伝送ライン28もさらにＵ字形としなければ
ならず、摺動を軽くするのは非常に困難になる。Similarly, when one of the transmission lines 25 is U-shaped, in order to increase the length of the entire transmission line, the transmission lines 23, 24, 25 must be set long, and the length and width of the transmission lines 23, 24, 25 must be set long. It becomes a continuous variable delay device which is long in either direction, and the precision must be further increased in order to prevent the sliding from becoming heavier. In order to make the continuously variable delay device 20 compact and to increase the delay amount, multiple transmission lines may be used as shown in FIG. 4 (b), but the number of U-shaped transmission lines increases and fixed transmission is performed. The line 28 also needs to be U-shaped, which makes it very difficult to reduce sliding.
つまり、連続可変遅延器20においては、伝送ライン25を
Ｕ字形一体構造にて形成した場合、一端25a、他端25b間

作業が行なわれており、組立作業の効率化及び製品の均
質化を達成することができない。That is, in the continuously variable delay device 20, when the transmission line 25 is formed in a U-shaped integrated structure, it is difficult to make the parallelism between the one end 25a and the other end 25b and the dimensions precise. . As a result, even when the continuous variable delay device 30 is manufactured, the work of disposing the transmission lines 23, 24, 28 at the positions of the one end 25a and the other end 25b of the U-shaped transmission line 25 is performed. It is not possible to achieve work efficiency and product homogenization.
また、伝送ライン25のＵ字形部分のみ一方向に突出して

体に側部から移動板26を固定しなければならず、この部
分の強度と、信号への影響が問題となる。Further, only the U-shaped portion of the transmission line 25 is projected in one direction, an extra space must be taken, and the moving plate 26 must be fixed to the transmission line 25 itself from the side portion. Is a problem.

In the first invention and the second invention, the entire transmission line is lengthened to increase the delay amount. An object of the present invention is to provide a continuously variable delay device in which a movable transmission line can slide lightly with respect to a fixed transmission line even when the number of sliding points is increased.
