To provide an injection device which can efficiently accelerate an injection object.SOLUTION: An outer coil 11 has an annular shape with an object injection direction as a central axis, and into which current I1 flows clockwise. An inner short circuit coil 12 has an annular shape having an outer surface 12B and an inner surface 12C, and accelerates an object due to a magnetic field generated by flowing an induction current I2 guided to a magnetic field generated by the current I1 flowing into the outer coil 11, into the inner surface 12C. A clearance 12A is provided in the annular shape of the inner short circuit coil 12, and the outer surface 12B and the inner surface 12C are connected to each other by surfaces 12D and 12E separated by the clearance 12A. The induction current I2 flows from the outer surface 12B through a surface 12D into the inner surface 12C, flows clockwise into the inner surface 12C, and flows from the inner surface 12C through a surface 12E into the outer surface 12B.SELECTED DRAWING: Figure 8
【課題】射出対象物を効率的に加速することが可能な射出装置を提供する。【解決手段】外側コイル11は、物体の射出方向を中心軸とする環状形状を有し、時計回りに電流I1が流れる。内側短絡コイル12は。外側表面12Bと内側表面12Cとを有する環状形状を有し、外側コイル11を流れる電流I1により生じた磁場に誘導された誘導電流I2が内側表面12Cを流れることで生じる磁場によって物体を加速する。内側短絡コイル12の環状形状には間隙12Aが設けられ、外側表面12Bと内側表面12Cとは、間隙12Aによって離隔された面12D及び12Eによって連結される。誘導電流I2は、外側表面12Bから面12Dを通って内側表面12Cに流れ込み、内側表面12Cを時計回りに流れ、内側表面12Cから面12Eを通って外側表面12Bへ流れる。【選択図】図8
