Description

板状部４１２は、密閉筐体４１の第２側面部４１Ｄの一部を構成し、当該板状部４１２の略中央部分には、開口部４１２１が形成されている。この開口部４１２１には、上記水晶拡散板６が嵌め込まれる。また、板状部４１２は、熱伝導性を有する金属により構成され、本実施形態では、アルミニウムにより構成されている。
また、板状部４１２のＹ方向側に位置する第１部位４１２２には、熱伝導部ＴＣ１が熱伝導可能に接触され、板状部４１２のＹ方向とは反対方向側に位置する第２部位４１２３には、熱伝導部ＴＣ２が熱伝導可能に接触される。また、第１部位４１２２には、プリズムベース４２Ｕが固定され、第２部位４１２３には、プリズムベース４２Ｌが固定される。このため、空芯コイルＣＬの温度が上昇すると、コイル保持部５６２，５７２の熱は、熱伝導部ＴＣ１，ＴＣ２に伝導され、当該熱伝導部ＴＣ１，ＴＣ２の熱は、板状部４１２に伝導される。
なお、第１部位４１２２及び第２部位４１２３は、本発明の熱伝導部位に相当する。
The plate-like portion 412 constitutes a part of the second side surface portion 41 D of the closed casing 41, and an opening 4121 is formed in a substantially central portion of the plate-like portion 412. The crystal diffusion plate 6 is fitted into the opening 4121. Moreover, the plate-like part 412 is comprised with the metal which has thermal conductivity, and is comprised with aluminum in this embodiment.
In addition, the heat conducting portion TC1 is brought into contact with the first portion 4122 located on the Y direction side of the plate portion 412 in a heat conductive manner, and the second portion located on the side opposite to the Y direction of the plate portion 412. The heat conducting portion TC2 is brought into heat conductive contact with 4123. The prism base 42U is fixed to the first portion 4122, and the prism base 42L is fixed to the second portion 4123. Therefore, when the temperature of the air core coil CL rises, the heat of the coil holding portions 562 and 572 is conducted to the heat conducting portions TC1 and TC2, and the heat of the heat conducting portions TC1 and TC2 is conducted to the plate-like portion 412 Be done.
The first portion 4122 and second portion 4123 is equivalent to the heat transfer guide portion position of the present invention.
