Title: Image forming device
Inventor: KURODA HIROYUKI
IPC: G03G15/00
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To reduce working burden of a user by selecting a reference size among two or more kinds of detected document sizes and imaging a reference mark at a prescribed position on recording paper corresponding to the reference size. SOLUTION: In copying in which different sizes of documents coexist, many sizes of recording paper are fed and imaging is performed, a reference mark for facilitating a post-processing for a user is imaged on recording paper of a large size in the copying. As for the reference mark, a 1-dot line of about 1 mm is imaged to the inside from both upper and lower sides at a paper passing direction center position of A3 for copying in which A3 and A4 coexist, for instance, so that recording paper of a large size may be a reference when the recording paper is folded according to other small sizes as a post-processing of recording paper for the user. Generally, as the reference mark, a 1-dot line of a several mm length is desirable so as not to affect copied image. By the reference mark, the user can easily and exactly recognize a bending position of A3 paper.

Abstract: PURPOSE:To reduce shear droop in shearing a steel plate with an upper blade and a lower blade facing each other by forming the laser work a sharp V-cut groove along a cutting line either on the upper blade side or on the lower blade side of the steel plate. CONSTITUTION:A groove 11 worked by laser is sharply V-formed at the bottom, so it has a large effect of reducing shear droop, and abrasion or damage is eliminated since any cutter is not used. Width of the cut groove 11 can be made smaller by throttling width of the laser beam, which has effect of increasing stress concentration and reducing shearing force, and shearing of a thick steel plate 1 is made possible. Then if the bottom of the cut groove 11 is cooled by liquid nitrogen or the like so the steel plate 1 becomes locally fragile, shearing force is further reduced and effect of shear droop can be larger.

Abstract: PURPOSE:To detect all ''0'' or ''1'' information of a prescribed bit number in input data with simple constitution by obtaining respectively a detected output of the all ''0'' or ''1'' information by the least or the most significant bit of a shift register. CONSTITUTION:When an input data is all logical ''0'', no clock is inputted to the shift register 11 and an output terminal Q1 is logical 0.
