摘要： A signal processing circuit includes: multiple digital-signal processing units operating in parallel each including a selecting unit for selecting one of multiple systems of input picture signals, a double-speed converting unit for writing the data equivalent to one field of the picture signal selected by the selecting unit in field memory, and simultaneously reading the data equivalent to one field from the field memory twice at double speed, thereby converting the frequency of the picture signal into double speed, a reading unit for reading the picture signal converted into double speed by the double-speed converting unit and temporarily stored in line memory, and a correction processing unit for subjecting the picture signal read by the reading unit to predetermined correction processing; and a control unit for performing the selection control of the multiple systems of picture signals, and the read position control of a picture signal from the line memory.

摘要： A coating mechanism is provided with a supply roller that rotates in contact with, and applies treatment liquid to, conveyed paper. A control section controls the rotational velocity of the supply roller such that the rotational velocity when applying the treatment liquid to a first sheet of paper after commencement of application of the treatment liquid is slower than the rotational velocity when applying the treatment liquid to a second sheet of paper. An increase in the coating amount caused by an initialization operation is offset by a reduction in the amount of treatment liquid supplied caused by decreasing the rotational velocity of the supply roller, thereby inhibiting the occurrence of a disparity between the coating amount of treatment liquid applied to the first sheet of paper after commencement of treatment liquid application and the coating amount of treatment liquid applied to the second sheet of paper.
摘要翻译：涂布机构设置有与所传送的纸接触并与处理液接触的供给辊。控制部控制供给辊的旋转速度，使得在开始施加处理液之后将处理液施加到第一张纸时的旋转速度比将处理液施加到第二片时的旋转速度慢的纸。由初始化操作引起的涂布量的增加由于通过降低供给辊的旋转速度而导致的处理液的量的减少而被抵消，从而抑制了施加到供给辊的处理液的涂布量之间的差异处理液施用开始后的第一张纸和施加到第二张纸上的处理液的涂布量。
