摘要： Two pairs of legs are fitted under two side plates of an electrophotography apparatus, respectively. The two legs in one pair fitted under one of the side plates are disposed on either side of and are spaced from a point which is a cross point of a line joining these two legs, and a line perpendicular to this line, which perpendicular line passes through a projected point obtained by projecting the center of gravity of the electrophotography apparatus onto a horizontal plane on which the apparatus is set up. The two legs in the pair fitted under the other one of the side plates are disposed on either side of and are spaced from a point which is a cross point of a line passing these two legs and a line perpendicular to this line, which perpendicular line passes through the projected point of the center of gravity. The ratio of a shorter distance to a longer distance, of two distances: one between the two legs in a pair and the other between the two legs in the other pair is set to a value of 1/5 to 1/3. With such a arrangement, a defect in an image caused by a distortion in said side plates, due to a position change in the center of gravity of the electrophotography apparatus can be prevented.
摘要翻译：两对腿分别安装在电子照相设备的两个侧板下方。安装在一个侧板之下的一对中的两条腿设置在与连接这两条腿的线的交叉点的一侧上的一侧上，并且与垂直于该直线的线垂直的线通过将电子照相设备的重心投影到设置有该设备的水平平面上而获得的投影点。配对在另一个侧板下方的两条腿设置在通过这两条腿的线的交叉点和垂直于该线的一条线的任一侧上并与之隔开，该垂直线穿过重心的投影点。两个距离之间的较短距离与较长距离的比例：一对中的两条腿之间的比例和另一对中的两条腿之间的比例设置为1/5至1/3的值。通过这样的布置，可以防止由于电子照相设备的重心位置变化而导致的所述侧板的变形引起的图像缺陷。

摘要： A thermal transfer printer has a platen and a thermal head between which are pinched a transfer paper sheet and an ink film, so that the ink is transferred from the ink film to the transfer paper sheet as heat is applied to the transfer paper sheet by the thermal head. The film is supplied by a supply roll and is taken-up by a take-up roll. The thermal head is swingable between a position where it contracts the platen and a position away from the platen. When the thermal head is in the position away from the platen, the distance therebetween is greater than the maximum diameter of the supply roll. A film drum can hold a plurality of films each being constituted by the supply roll and the take-up roll. Swing arms are provided for demounting the supply roll of a selected film from the film drum and for bringing the same to a position away from the film drum, and also for returning the same from this position to the film drum. During the movement of the supply roll between the position in the film drum and the position away from this position, the thermal head is moved away from the platen so as not to hinder the movement of the supply roll.
摘要翻译：热转印打印机具有压板和热敏头，两者之间夹有转印纸和油墨膜，使得油墨从转印纸张转印到转印纸上热头。胶片由供应辊供应并被卷取辊卷取。热敏头可在其收缩压板的位置和远离压板的位置之间摆动。当热敏头位于远离压板的位置时，它们之间的距离大于供给辊的最大直径。薄膜滚筒可以容纳由供给辊和卷取辊构成的多个薄膜。提供摆动臂用于从胶卷鼓上拆下所选胶片的供应卷，并将其提供到远离胶卷鼓的位置，并将其从该位置返回到胶卷鼓。在供给辊在胶片卷筒的位置与远离该位置的位置之间运动期间，热敏头远离压板移动，以免阻碍供纸辊的移动。

摘要： A fixing unit that is provided in an image forming device and fixes a toner image transferred to paper is constructed of two belts, belt guides each of which guides the inner periphery of each of the belts, a heating member arranged in one of the belts or heating members arranged in both of the belts, a drive roller for driving the inner periphery of the belt, wherein the belts pinch paper on both surfaces thereof by the belt guides and carry the paper. This construction can realize a fixing unit reduced in size and capable of printing images at high speeds and shortening a rise time that elapses until the fixing unit reaches a fixable temperature.
