摘要： A digital signal processing system comprising a compressor, an expander and a scale-down circuit. The compressor includes non-block frequency analyzer that frequency analyzes the digital input digital signal, without dividing it into block, to provide a frequency range signal in each of plural frequency ranges. A block frequency analyzer divides the frequency range signals into blocks and performs a block frequency analysis of each block of the frequency range signals to provide a block of spectral coefficients. A quantizer quantizes the block of spectral coefficients from the block frequency analyzer to provide a block of a compressed signal. The expander includes a block frequency synthesizer that performs a block frequency synthesis to transform, from the frequency domain to the time domain, the spectral coefficients in each of the frequency ranges in each block of the compressed signal to provide, in each of the frequency ranges, a block of a reproduced frequency range signal. A non-block frequency synthesizer synthesizes the reproduced frequency range signals, without dividing them into blocks, to provide the digital output signal. Finally, the system includes a scale-down circuit that scales down values in the block frequency analysis performed by the block frequency analyzer or the block frequency synthesis performed by the block frequency synthesizer. The scale-down circuit operates to cause the noise levels resulting from scaling down the values to be different in each of the frequency ranges.

摘要： A medium processing apparatus for processing a medium ejected from an image forming apparatus includes a conveyor, a slit, a medium processing device, a stopper, and detectors. The conveyor conveys the medium ejected from the image forming apparatus. The slit communicates with an opening of a housing into which a medium is manually inserted from outside and includes a placement face on which the inserted medium is placed. The placement face has a first side and a second side orthogonal to the first side. The first and second sides are not parallel to a direction in which a side face of the housing extends. The medium processing device processes the medium conveyed by the conveyor or the medium placed on the slit. The stopper regulates edges of the medium along the first and second sides of the placement face. The detectors are disposed on the stopper to detect the medium.

摘要： A sheet separation device configured to separate a two-ply sheet, in which two sheets are bonded together at a portion, includes a rotator, a nipping member disposed opposite the rotator and configured to nip the two-ply sheet with the rotator, a conveyor configured to convey the two-ply sheet between the rotator and the nipping member, and a winding member disposed adjacent to the rotator. The conveyor conveys the two-ply sheet with a bonded portion of the two-ply sheet being an upstream end or a downstream end of the two-ply sheet in a conveyance direction of the two-ply sheet. The winding member winds the two-ply sheet around the rotator, to create a difference in winding circumferential length between the two sheets and separate the two sheets. The sheet separation device further includes control circuitry configured to adjust a winding amount of the two-ply sheet around the rotator.

摘要： A sheet folding apparatus includes: a folded part forming unit that forms a folded part on the sheet by nipping a curved portion formed on a part of the sheet between an upstream first sheet conveying unit and a downstream second sheet conveying unit by holding a part of the sheet by the first sheet conveying unit and applying conveying force to the sheet to reverse the sheet upstream by the second sheet conveying unit; and a sheet leading end detection unit disposed downstream of or at almost same position as the second sheet conveying unit. The sheet is conveyed based on a detection timing of the sheet leading end detection unit such that the leading end of the sheet protrudes by a predetermined protrusion amount from the second sheet conveying unit immediately before applying conveying force to the sheet to reverse the sheet.

摘要： A sheet folding apparatus includes: a first sheet conveying unit; a second sheet conveying unit that is disposed downstream of the first sheet conveying unit; a folded part forming unit that forms a folded part on a sheet by nipping a turned-back portion formed on a part of the sheet between the first sheet conveying unit and the second sheet conveying unit; a second conveying path that bifurcates from the first conveying path and in which a sheet with the folded part is conveyed; and a pushing member that is movable between a pushing position at which the pushing member pushes the turned-back portion toward the folded part forming unit and a retracted position. The pushing member also serves as a changing unit that changes a direction of a leading end of the sheet that is conveyed in the first conveying path into a direction toward a second conveying path.
