    • The joint mechanism includes a first link, a second link, a third link, a shaft supported on the second link to be rotatable about an axis thereof, and movable in an axis direction thereof, a first worm and a second worm mounted on the shaft, a first worm wheel in mesh with the first worm to pivotally move the first link with respect to the second link, and a second worm wheel in mesh with the second worm to pivotally move the third link with respect to the second link. The first link and the third link are pivotally moved in opposite directions to each other by rotating the shaft, and pivotally moved in identical directions to each other by moving the shaft in the axis direction.

    • A syringe drive device 15 according to the present invention includes: an outer tube fixing portion 31 that detachably fixes an outer tube 22 of a syringe 16; a plunger holder 21 that holds a plunger 17 of the syringe 16; and a drive portion that moves the plunger holder 21 along an axis of the syringe. The outer tube fixing portion 31 includes: a flange catcher 33 facing a rear end of a flange 22a of the outer tube 22, the rear end being located far from the plunger 17 to be pushed; slide portions 34 and 35 that are located in front of a front end of the flange 22a to hold the flange 22a between the flange catcher 33 and the slide portions, the front end being located close to the plunger 17 to be pushed; slide guides 36 and 37 that support the slide portions 34 and 35 so as to be slidable along the axis of the syringe; and a slide portion operation mechanism that is switchable between a first state where the slide portions 34 and 35 slide along the axis of the syringe, and a second state where the slide portions 34 and 35 are held at positions to hold the flange 22a between the flange catcher 33 and the slide portions.
    • 根据本发明的注射器驱动装置15包括:可拆卸地固定注射器16的外管22的外管固定部31; 保持注射器16的柱塞17的柱塞保持件21; 以及沿着注射器的轴线移动柱塞保持器21的驱动部。 外管固定部分31包括:面对外管22的凸缘22a的后端的凸缘捕获器33,后端远离柱塞17被推动; 位于凸缘22a的前端前方的滑动部分34和35,以将凸缘22a保持在凸缘捕获器33和滑动部分之间,前端靠近柱塞17定位以被推动; 滑动引导件36和37,其支撑滑动部分34和35以沿着注射器的轴线滑动; 以及滑动部分操作机构,其可以在滑动部分34和35沿着注射器的轴线滑动的第一状态和第二状态之间切换,其中滑动部分34和35被保持在将凸缘22a保持在 凸缘捕获器33和滑动部分。
