Abstract

PURPOSE:To improve the operability of a pressing device by providing an operating lever which selectively locates a pressing lever in a pressing position where two rollers are brought into pressure contact with each other, and a releasing position where the pressure between both rollers is released. CONSTITUTION:To release the pressure between both rollers 1, 2, an operating lever 20 is turned to releasing position 20A. An eccentric shaft 11 is rotated by the turning of the lever 20, by which the center thereof is moved upward and the distance between the same and an engaging pin 9 is decreased. Namely, the fulcrum which is the rotating center of a pressing lever 12 moves upward, and the lever 12 is butted at its leading end part to a stopper part 14b and therefore a fulcrum shaft 15 is moved upward by as much as the center of the shaft 11 moved upward in accordance with the ratio thereof, whereby the distance between the same and the pin 9 is reduced. Hence, the pressure between both rollers 1, 2 is released.
