摘要： A heat roller fixing device includes a heat roller, a press roller, and at least one curl correction mechanism. The curl correction mechanism is constituted by three discharge rollers that form an S-shaped nip portion. The curl correction mechanism is arranged on a recording medium discharge side of a fixing nip portion which is formed at a contact portion between the heat roller and the press roller.

摘要： An apparatus for embedding information in a signal includes a band dividing device, a block divider, a quantization portion, a signal replacement portion, a mean difference addition portion, a mean calculation portion, and a band synthesis portion. The band dividing device divides the signal into transform coefficients over a plurality of frequency bands. The block divider divides one frequency band into a plurality of blocks in accordance with a previously determined block size. The quantization portion calculates for each block, a mean value M of the transform coefficients in the block, and subjects the mean value M to linear quantization, using a previously determined quantization step-size Q to calculate a quantization value. The signal replacement portion replaces the quantization value for each block, on the basis of the quantization value and the value of the information to be embedded. The mean difference addition portion subjects the replaced quantization value, for each block, to inverse linear quantization using the quantization step-size Q to calculate a mean value M′, and adds a difference DM between the mean value M′ and the mean value M to all the transform coefficients in the block. The mean calculation portion calculates a mean value LM of the transform coefficients in the frequency band after the addition of the difference DM. The band synthesis portion reconstructs a signal in which the information has been embedded using the frequency band after the addition of the difference DM and the other frequency bands.
摘要翻译：用于在信号中嵌入信息的装置包括带分割装置，块分割器，量化部分，信号替换部分，平均差加法部分，平均计算部分和频带合成部分。频带划分装置将信号划分成多个频带的变换系数。块分割器根据先前确定的块大小将一个频带划分成多个块。量化部分针对每个块计算块中的变换系数的平均值M，并使用预先确定的量化步长Q对平均值M进行线性量化，以计算量化值。信号替换部分基于量化值和要嵌入的信息的值替换每个块的量化值。平均差分加法部分使用量化步长Q对每个块对替换的量化值进行逆线性量化，以计算平均值M'，并将平均值M'和平均值M 到块中的所有变换系数。平均计算部分计算差DM之后的频带中的变换系数的平均值LM。频带合成部分在添加差分DM和其他频带之后，使用频带重建信息已被嵌入的信号。
