摘要： A belt driving device includes an endless belt, a tension roller, a shaft member, deviation transfer members, and biasing members. The deviation transfer members are fitted over the shaft member in such a manner as to adjoin respective of opposite ends of the tension roller in an axial direction of the tension roller. Of the deviation transfer members, at least that deviation transfer member which is located on a downstream side in a deviation direction along the axial direction is movable together with the endless belt along the shaft member. Each of the biasing members has an acting end pivotally supported on an associated one of the deviation transfer members and a base end pivotally supported on an associated one of apparatus frames at a predetermined position.

摘要： A printer with a printhead pressure adjusting mechanism including a thermal head, a platen drum, an adjusting mechanism, a detection device [e.g., switch(es)] and a control unit. The thermal head transfers ink of an ink ribbon onto recording paper by heat generation. The platen drum sandwiches the ink ribbon and the recording paper under pressure together with the thermal head. The adjusting mechanism adjusts the pressure being applied to the thermal head when pressing the thermal head. The detection device detects the size of the recording paper. The control unit controls the adjusting mechanism in order to adjust the pressure being applied to the thermal head in accordance with the detected size of the recording paper.

摘要： An image forming apparatus prevents link members for monochrome and for color from coming off while suppressing an increase in rotatory torque and a deficiency of clutch capacity for transmitting a driving force to a cam shaft. Coming-off protection sections for preventing the coming off of a second link member which is the link member for color is provided in a cam section for monochrome. In other words, it is not necessary to provide a coming-off protection section in a second cam section which is a cam section for color requiring a large rotatory torque. This eliminates the need for a coming-off protection section of the cam section for color to act on the link member for color when a cam is turned by a driving source.

摘要翻译： 图像形成装置防止用于单色和颜色的连接构件脱离，同时抑制旋转扭矩的增加和用于将驱动力传递到凸轮轴的离合器容量的不足。 用于防止作为用于颜色的连接构件的第二连杆构件脱落的防脱部设置在用于单色的凸轮部中。 换句话说，不需要在作为用于需要大的旋转扭矩的颜色的凸轮部的第二凸轮部中设置脱离保护部。 这消除了当凸轮被驱动源​​转动时需要用于颜色的凸轮部分的脱落保护部分作用于连杆构件上以进行颜色。

摘要： Preventing link members for monochrome and for color from coming off while suppressing the occurrence of an increase of a rotatory torque and a deficiency of clutch capacity for transmitting a driving force to a cam shaft is sought. Coming-off protection sections (second and third coming-off protection sections (236), (237)) for preventing the coming off of a second link member 22 which is the link member for color is provided in a cam section for monochrome (first cam section 233). In other words, it is not necessary to provide a coming-off protection section in a second cam section 234 which is a cam section for color requiring a large rotatory torque. This eliminates the need for a coming-off protection section of the cam section for color to act on the link member for color when a cam 23 is turned by a driving source, thereby making it possible to suppress the occurrence of the increase of the rotatory torque and the deficiency of clutch capacity for transmitting the driving force to the cam shaft.
