Abstract: A rotary cutter unit includes: a cutter roll; an anvil roll parallel to the cutter roll; two pairs of rotatably-supporting portions, each pair disposed at respective opposite ends of each of the two rolls; a pair of air springs each installed to apply pressure to a respective one of the pair of rotatably-supporting portions of one roll; and a pair of spring elements each installed to apply pressure to a respective one of the pair of rotatably-supporting portions of the other roll, in a direction opposed to the pressure application of the air springs. The air springs and spring elements apply pressures to respective corresponding ones of the pairs of rotatably-supporting portions, in opposite directions sandwiching the two rolls. Each rotatably-supporting portion is slidable in directions which cause pressure applied from a corresponding one of the pair of air springs and the pair of spring elements to increase and decrease.

Abstract: A cutter roll and an anvil roll, with which it is possible to control deformation in the axial direction, and a rotary cutter having the same. A roll 101, 210 for a rotary cutter includes: a barrel portion having a circumferential surface and a pair of end surfaces located respectively at opposite ends of the circumferential surface; a pair of first depressions 113, 213 having a ring shape or a cylindrical shape and located respectively at the pair of end surfaces of the barrel portion, the pair of first depressions each having a depth direction that is parallel to an axis of the barrel portion; a pair of first bearings 152, 252 located respectively in the pair of first depressions and being in contact with outer walls of the first depressions; and a pair of first bearing boxes 156 located on an outside of the pair of first depressions and having support portions 151b, 251b to be in contact with a support frame or a pressure mechanism, the pair of first bearing boxes supporting the respective bearings.

Abstract: A decoding start controller is capable of appropriately decoding pictures up to the final picture, even if the amount of the data stored in a bit-stream buffer is reduced, as a result of partial storage of the data in an internal local buffer. Further, the decoding start controller is capable of decoding extremely short bit-stream data. If completion information, which is sent from an input side of the bit-stream data and represents completion of input of the bit-stream data, is detected, a decoding start instruction signal is output to a variable-length decoder regardless of a value of VBV occupancy. In short, when the amount of the data stored in the bit-stream buffer connected to the decoder having the decoding start controller, is equal or greater than the value of VBV occupancy, the decoding start instruction signal will usually be sent to the variable-length decoder: namely, so-called decoding start control operation based on value of VBV occupancy.

Abstract: A printing apparatus and a facsimile equipment incorporating the same according to the present invention are constituted as such that, when printing an original of, for example, A3 size by a printer of A4 size, the original read in the subscanning direction at reading is printed in the main scanning direction at printing, and at the same time, the image data in the main scanning direction and subscanning direction are enlarged or reduced respectively for printing so as to bring the length/widthwise ratio of a hard copy thus obtained equal to those of the original, so that when the facsimile including a A4 size printer receives the original of A3 size, the hard copy without distortion can be obtained with the smaller printer as compared with the original.
