An oscillation circuit 11, a voltage control circuit 12, and a main dielectric resonator 13 are provided on the internal bottom surface of the O, and a cover 14 is provided on the upper opening surface.
is attached, and a sub dielectric resonator 15 is provided opposite the main dielectric resonator 13 in the cover 14 .

The oscillation frequency can be controlled by adjusting the distance between the dielectric resonator 13.
The distance between the 15 is adjusted using a long adjustment screw 16. That is, the adjustment screw 16 was screwed into a female threaded portion formed on the cover 14, the sub dielectric resonator 15 was attached to the lower end, and the upper end was made to protrude outside the cover 14.

。[Problem to be solved by the invention 1i] In the above-described conventional band reflection oscillator, when the dielectric resonators 13 and 15 are in the most distant state, the upper end of the adjusting screw 16 is connected to at least the sub-dielectric resonator. It protrudes to the outside by a length greater than the amount of vertical movement of the body resonator 15 (
As shown in FIG. 3(a), there is a drawback that mounting is difficult when the mounting space is narrow.

を変動させるおそれかあった。In addition, in the conventional case where a female thread is formed directly on the cover and screwed into the adjustment screw, the cover (generally made of aluminum alloy) has low rigidity, so the friction caused by the screwing causes metal powder to be generated, causing the dielectric resonator to There was a risk that the oscillation frequency would fluctuate if it adhered to the casing or accumulated inside the case.

業か煩雑であった。Furthermore, the screwing with the female thread formed on the cover tends to cause rattling, and therefore a lock nut 17 is required to fix the adjustment screw, and in addition to the adjustment work, the work of fixing the lock nut 17 is also required. The work was complicated because it had to be done.

The purpose of this invention is to provide a band-pass reflective oscillator with high performance.
