    摘要： A bellows pump which is disclosed herein has two bellows made of a plastic material and provided with liquid inlet and outlet ports for transferring a liquid by expanding and contracting the bellows. The bellows pump comprises cylinder cases in each of which the bellows is vertically expandably and contractably contained and mounted at its access port side to a ceiling of said cylinder cases, gas pumping means for alternately feeding a compressed gas from a lower end thereof into the cylinder cases, a pair of rods passed through bottoms of the cylinder cases and fixed to the lower ends of the bellows, and adapted to be moved in response to the expansion and contraction of the bellows, and actuating means adapted to be operated in response to the up and down movement of the rods.

    摘要： A fixing device includes a heat roller, which is rotatably mounted to a frame, a press roller, which is rotatably mounted to the frame, and a press mechanism for pressing the press roller against the heat roller. The press mechanism has a displacement member that is displaceable in a press direction, a bearing portion that is movable in the opposite direction relative to the displacement member and supports the press roller at a shaft portion thereof, an urging member for urging the bearing portion in the press direction, and displacing structure for displacing the displacement member between a first position corresponding to a non-press position and a second position corresponding to a press position. The urging force of the urging member in the press direction is reinforced by action of the bearing portion, which is displaced in the opposite direction relative to the displacement member when the displacement member is displaced from the first position to the second position.

    摘要翻译： 定影装置包括可旋转地安装到框架上的加热辊，可旋转地安装在框架上的加压辊，以及用于将加压辊压靠在加热辊上的加压机构。 所述按压机构具有位移构件，所述移动构件能够在加压方向上移动，所述移动构件能够相对于所述移动构件在相反方向上移动，并且在所述轴部处支撑所述加压辊，所述推动构件用于将所述支承部分推压 按压方向和用于使位移构件在对应于非按压位置的第一位置与对应于按压位置的第二位置之间移位的移位结构。 推动构件在压制方向上的作用力通过轴承部分的作用而被增强，当位移构件从第一位置移位到第二位置时，支承部分相对于位移构件在相反方向上移位。
