摘要： A technique is provided in which the inside and outside of an exposure device is prevented from being adversely affected by leakage of light by setting an inspection output most suitable for high-power LD. A light-leakage detection level is set correspondingly to output characteristics of each high-power LD, and respective thresholds thereof are previously stored. As a result, leakage of light can be determined in a lower-power state of 100 mW or less. Accordingly, even if leakage of light may occur, leakage of light can be determined before high-power light leaks, and the inside and outside of the device can be prevented from being adversely affected by light leakage.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus and a method for scanning the outer surface of a cylinder by which a margin for clamping the rear end of an image recording material with a rear end clamp is decreased when a sheet type image recording material is mounted on the outer surface of a recording drum for image recording, so that the image recording region of the recording material can be sufficiently obtained. SOLUTION: A rear end sensor 81 is provided near the rear end clamp 53 to detect the presence or absence of a printing plate on the sensing point. The rotation angle position of the recording drum 5 is fixed to the rear end clamp position based on the rear end position of the printing plate P detected by the rear end sensor 81, and the rear end of the printing plate P is clamped at the above position by the rear end clamp 53. Thus, the printing plate P is reliably fixed by the rear end clamp 53 and the margin for clamping the printing plate P by the rear end clamp 53 can be stably obtained while eliminating effect of variation in the manufacture of the printing plate P.

摘要： PROBLEM TO BE SOLVED: To form rimless image in a cylindrical drum scanner assembly having a curved platen for supporting a medium during exposure by a laser image scanner.
SOLUTION: In a cylindrical drum scanner assembly having a curved platen for supporting a medium during exposure by a laser image scanner, the device for positioning the medium includes a medium-feeding mechanism for feeding the medium onto the curved platen, and an assembly which ejects the medium from the medium feeding mechanism to the scanning area of the curved platen so as to form a rimless image on the medium.

摘要： PROBLEM TO BE SOLVED: To provide a system to accurately position films of two or more sizes, and remove distortion in an internal drum laser scanner assembly. SOLUTION: A device which comprises two or more slider assemblies, and positions the films in the drum scanner assembly, is provided with a first and a second horizontal end parts, a third and a fourth curvature side ends connected between the first and the second ends 22, 24, a curvature surface which forms a route of the curvature film from the first end to the second end, a curvature film platen 20 of concave shape arranged horizontally, and a film engaging member which is mounted relating to the platen, and is engaged with the carried film by the film platen. The film engaging member comprises a slider assembly which independently slides in the slider assembly, and a means which moves the slider assembly according to the size of the carrying film on the platen so as to arrange the all film engaging member along the platen in perpendicular direction against the film route.

摘要： PROBLEM TO BE SOLVED: To solve the problem that when the width of a plate which can be mounted on a drum of an external surface drum type image recording device is increased, a punch formation position for a plate needs to be changed to maintain precision of a drawing position, the problem that the cost rises when the number of punchers is merely increased, and the problem that a necessary puncher can not be arranged at a position where a punch hole is to be formed owing to conflict of punch standards, etc.
SOLUTION: The plate prepared on an upper plate 41 of a feed/discharge unit 20 is supplied to a drum 21 after various punch holes are formed at its front end by a punch unit 23. The punch unit 23 has six punchers movably arranged. Consequently, punch holes can be formed at 12 positions. Further, a punch hole for engagement with a positioning pin on the drum and a punch hole for releasing the pin can selectively be formed by the same puncher.

摘要翻译：要解决的问题为了解决当可以安装在外表面鼓型图像记录装置的滚筒上的板的宽度增加时，板的冲压成形位置需要改变为保持绘图位置的精度，当打孔机的数量仅增加时，成本上升的问题以及由于冲压标准的冲突而不能在必要的打孔机布置在要形成冲孔的位置的问题等等。解决方案：在进给/排出单元20的上板41上制备的板在其前端由冲压单元23形成各种冲孔之后被供应到滚筒21.打孔单元23具有六个打孔机可移动排列。因此，可以在12个位置形成冲孔。此外，用于与滚筒上的定位销接合的冲孔和用于释放销的冲孔可以由相同的冲孔机选择性地形成。版权所有（C）2004，JPO
