摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus, wherein the strength of the opening angle limiting mechanism of an opening/closing cover is increased. SOLUTION: A frame rear cover 26 is attached to the rear of a frame member 23. On the underside of the cover 26, an opening angle limiting mechanism 30 is disposed for limiting the opening angle of the opening/closing cover 24. The opening angle limiting mechanism 30 includes: a projecting plate 31 projecting in the direction of the inside face of the opening/closing cover 24; a first engagement projection 32 and second engagement projection 33 projecting from the projecting plate 31 almost perpendicular to it; a first cover locking part 34 disposed on the frame member 23; and a second cover locking part 35 disposed on the inside face of the frame rear cover 26. When the opening/closing cover 24 is opened only by a predetermined angle, the first and second engagement projections 32 and 33 are engaged with the first and second cover locking parts 34 and 35 respectively. As a result, rotating force applied in the direction in which the opening/closing cover 24 is opened is spread and received by the first and second cover locking parts 34 and 35.

摘要： PROBLEM TO BE SOLVED: To reduce manufacturing cost by easily mounting a guide member and facilitate handling in a paper feed tray. SOLUTION: In this paper feed tray 1, a guide member 2 is slidably installed by fitting a holding piece 2c formed on the lower surface of the guide member 2 to the side end edge of a rail hole 1b. An insertion hole 1c in which the holding piece 2c is inserted is formed at the end of the rail hole 1b. A beam-like claw part 1e having flexibility in the vertical direction is so formed near the end of the insertion hole 1c that closes the insertion hole 1c. The guide member 2 is easily installable on the paper feed tray 1 by pressing the holding piece 2c against the claw part 1e from the upper side of the paper feed tray 1 and inserting it into the insertion hole 1c while deflecting the claw part 1e. When the guide member 2 is slid to the insertion hole 1c, the holding piece 2c abuts on the claw part 1e, and the guide member 2 is prevented from being separated from the paper feed tray 1.

摘要翻译：要解决的问题：通过容易地安装引导构件并便于在进纸托盘中的处理来降低制造成本。
解决方案：在该送纸盘1中，通过将形成在引导构件2的下表面上的保持件2c安装到轨道孔1b的侧端边缘，可滑动地安装引导构件2。在轨道孔1b的端部形成有插入保持片2c的插入孔1c。在靠近插入孔1c的插入孔1c的端部附近形成有垂直方向具有挠性的梁状爪部1e。引导构件2可以通过从保持片2c从供纸托盘1的上侧压靠爪部1e并将其插入到插入孔1c中，同时使爪部1e偏转而容易地安装在供纸盘1上。当引导构件2滑动到插入孔1c时，保持件2c抵靠爪部1e，并且防止引导构件2与进纸盘1分离。版权所有（C）2007 ，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To make a carrier smoothly stop at a stop position while preventing deterioration in moving speed of the carrier due to contact of a printing head with a wiper member in a printer in which the carrier holding the printing head is moved beyond the wiper member during maintenance.
SOLUTION: It is judged whether or not the carrier reaches a wiping section (S11). When judged that the carrier reaches the wiping section, it is further judged whether or not a difference between a target position and a current position is set (S12). When the difference is not set (NO at S12), a difference between the target position and the current position is set as an initial delay amount (S13). When the difference is set (YES at S12), a difference (a current delay amount) between the target position and the current position in the corresponding cycle is calculated (S14). It is judged whether or not a difference (an actual delay amount) between the current delay amount and the initial delay amount exceeds a change amount for two cycles of the target position (S15). If the actual delay amount exceeds the change amount for two cycles of the target position, output to a DC motor is increased (S16).

摘要翻译：要解决的问题：为了使载体在停止位置平稳地停止，同时防止由于打印头与擦拭器部件的接触而导致的载体的移动速度的劣化，在打印机中，保持印刷头的载体为在维护期间超出擦拭器部件。解决方案：判断载体是否到达擦拭部（S11）。当判断为载体到达擦拭部时，进一步判断目标位置与当前位置之间的差是否被设定（S12）。当未设定差（S12为“否”）时，目标位置与当前位置之间的差被设定为初始延迟量（S13）。当设定差值（S12为“是”）时，计算出对应的周期中的目标位置与当前位置之间的差（当前延迟量）（S14）。判断当前延迟量与初始延迟量之间的差（实际延迟量）是否超过目标位置的两个周期的变化量（S15）。如果实际延迟量超过目标位置的两个周期的变化量，则向DC电动机的输出增加（S16）。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To obtain an image forming apparatus in which a variable display and a control section are protected against failure due to static electricity by preventing static electricity from being discharged to a flexible board from the outside of a housing while keeping the manufacturing cost at a low level. SOLUTION: The display unit 5 of an image forming apparatus is constituted by holding a liquid crystal display 52 with an outer frame 51 wherein the bearing portion 51a of the outer frame 51 is born on the housing 10 and fixed rotatably thereto. The liquid crystal display 52 is connected with a circuit board in the housing 10 through a flexible board 81. A portion exposed to the outside of the outer frame 51 from the vicinity of the bearing portion 51a of the flexible board 81 toward the interior of the housing 10 is covered with a protective portion 53 formed integrally with the outer frame 51. Since the creeping distance from the vicinity of the bearing portion 51a of the outer frame 51 to the portion exposed to the outside of the outer frame 51 of the flexible board 81 is increased, static electricity is not discharged to the flexible board 81 from the outside of the housing 10.

摘要翻译：要解决的问题：为了获得图像形成装置，其中可变显示和控制部分通过防止静电从壳体的外部排出到柔性板而被保护而免受静电故障，同时保持制造成本在低水平。解决方案：图像形成装置的显示单元5通过用外框51保持液晶显示器52而构成，外框51的轴承部分51a出现在壳体10上并可旋转地固定在其上。液晶显示器52通过柔性板81与壳体10中的电路板连接。从柔性板81的轴承部分51a附近暴露到外框架51的外侧的部分朝向内侧壳体10覆盖有与外框架51一体形成的保护部分53.由于从外框架51的轴承部分51a附近到暴露于柔性板的外框架51的外侧的部分的爬行距离 81增加，静电不会从壳体10的外部排出到柔性板81上。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To improve durability against a twisting stress of a supporting shaft and to prevent the supporting shaft from being broken in a printer wherein a cover main body freely openably and closeably supported to a housing body is always energized in the open direction by a spring attached on the supporting shaft of a hinge structure, and an opening/closing covering device with an improved operability when the cover is opened and closed is provided. SOLUTION: The sectional external shape of the supporting shaft 11 constituting the hinge structure of the cover main body is formed into an approximately elliptical shape with plane parts 11a on both sides so that it can be mounted only at a specified angle to a bearing part on the housing body side. In addition, the sectional shape of the inner wall face 11b is formed into an approximately elliptical shape with plane parts 11c on both sides which is a similar figure to the external shape so that the supporting shaft 11 is formed into hollow and the thickness of the hollow shaft is equalized. In addition, two linear thick padding parts 11d along the axial longitudinal direction are formed at mutually opposite positions of the plane parts 11c on both sides of the inner wall face 11b. The durability against the twisting stress of the supporting shaft 11 is improved by forming the thick padding parts 11d. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：为了提高耐支撑轴的扭转应力的耐久性，并且在打印机中防止支撑轴被破坏，其中盖主体可自由地可开启和可靠地支撑在壳体上总是在设置有铰链结构的支撑轴上的弹簧的打开方向，以及当盖打开和关闭时具有改进的可操作性的打开/关闭覆盖装置。解决方案：构成盖主体的铰链结构的支撑轴11的截面外形形成为大致椭圆形，其两侧的平面部11a形成为仅能以特定角度安装到轴承部分在壳体侧。此外，内壁面11b的截面形状形成为大致椭圆形，其两侧的平面部分11c与外部形状相似，使得支撑轴11形成为中空，并且其厚度空心轴相等。另外，在内壁面11b的两侧的平面部11c的相互相对的位置形成有沿轴向长度方向的两个线状的厚填充部11d。通过形成厚的衬垫部11d来改善支撑轴11的扭转应力的耐久性。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To easily adjust the posture of a laser scanning unit even at a low cost in a laser beam printer. SOLUTION: The laser scanning unit 5 is supported in freely rotating with a frame 40 of a case. While the frame 40 is provided with a worm gear 36, a rack 29 is formed in the laser scanning unit 5. If the worm gear 36 is rotated, the driving force is transmitted to the laser scanning unit 5 through the rack 29, then the laser scanning unit 5 is rotated. Thereby, the posture of the laser scanning unit 5 is adjusted. COPYRIGHT: (C)2007,JPO&INPIT
