Claims

[Claims for Utility Model Registration] (1) A pair of roller frames, a drive roller whose both ends are supported by the roller frame, a pressure roller provided movably with respect to the drive roller, and this pressure roller. A pressure regulating spring presses a bearing that rotatably supports both ends of the pressure roller to press the pressure roller against the drive roller, and a camshaft whose both ends are rotatably supported by the roller frame is equipped with an operating lever and a cam. and a crimping release mechanism in which a crimping release lever, which is swung by the rotation of the crimping roller, is connected to a bearing of the crimping roller. A pressure bonding developing machine equipped with a holding mechanism that prevents rotation. (2) The holding mechanism fixes the rear end of the lever to the camshaft, connects one end of the engagement lever to the tip of the lever, and connects the other end of the engagement lever with a pin provided on the roller frame. A linear guide edge is formed that is movably supported by the guide edge, a cutout part that can be engaged with the pin is provided in the middle of the guide edge, and one side of the cutout part on the camshaft side is tapered outwardly. One end of the guide lever is rotatably supported on a support plate attached to the other end of the engagement lever, and the other end of the guide lever is rotated in the direction of the notch at a position facing the front side of the tapered edge. 2. The pressure developing machine according to claim 1, wherein a stopper pin for preventing the guide lever from swinging is attached to the support plate or the engagement lever, and a spring is provided for deflecting the switching guide toward the stopper pin.
