    摘要： An inkjet printer includes plural inkjet heads that are aligned in a head alignment direction to form a head row, a blower that blows air to the head row from one side along the head alignment direction, and an aspirator that is disposed on an extended line of the head row and on the other side along the head alignment direction for aspirating air through its aspirator port. The aspirator includes a tubular duct that extends from the aspirator port toward the head row.

    摘要： An image reading apparatus includes a light emitting element, a luminance calculating unit, a light amount setting unit, and a storing unit. The light amount setting unit, in each line period, causes the light emitting element to emit a light with gradually changing a reference light amount from a reference light amount set as a default value from among a plurality of reference light amounts stored in the storing unit, identifies a reference light amount so that the luminance calculated by the luminance calculating unit is within a predetermined range, sets the identified reference light amount as a default value for the next line period, and causes the storing unit to store that reference light amount.

    摘要： An inkjet printing machine includes: a paper feeder; a transfer unit having a conveyer belt with a plurality of suction holes formed thereon and transferring a sheet fed by the paper feeder while sucking and holding the sheet on the conveyer belt by suction force generated at the suction holes; inkjet heads discharging ink on the transferred sheet; and a controller performing printing by controlling the above components, wherein the suction holes of the conveyer belt are arranged so that, when the leading edge of the sheet in the transfer direction does not overlap with the suction holes, the trailing edge of the sheet also does not overlap with the suction holes, and the controller controls the paper feeder to feed a sheet at a timing when the leading edge and the trailing edge of the sheet in the transfer direction do not overlap with the suction holes.

    摘要： A printing machine includes a printing unit which performs printing while transferring a sheet at a printing transfer speed, a circulation transfer unit which receives the sheet after simplex printing and transfers the sheet by reversing the sheet upside down, during duplex printing; and a paper refeed unit which refeeds, to the printing unit, the sheet transferred by the circulation transfer unit after simplex printing, wherein the circulation transfer unit includes a reversing unit which receives the sheet at the printing transfer speed, reverses the sheet upside down by switching back the sheet and accelerates the sheet up to a circulation transfer speed which is higher than the printing transfer speed when sheet transfer is restarted after temporal stop in the switching back, and a horizontal transfer unit which transfers the sheet switched back by the reversing unit, at the circulation transfer speed.

    摘要： After powered on, a check unit rewrites a lookup table in a memory of a programmable logic circuit unit to one of lookup tables in its own memory so as to switch a circuit state that a logic circuit implements. When the check unit outputs an inquiry signal in this state and an identification signal which responds to the inquiry signal is input into the check unit from a check circuit of a sub substrate via the logic circuit and a port, the sub substrate corresponding to the identification signal is specified as a connection destination of connectors. The circuit state of the logic circuit is optimized on the basis of a result of specification of the sub substrate as the connection destination obtained by repeating the above-mentioned operation.

    摘要： An inkjet printing machine includes a controller and performs margin-less printing on a base material on the basis of image data having a size larger than that of the base material by discharging ink from an inkjet head while relatively moving the base material and the inkjet head for one cycle of reciprocation or more in a main-scanning direction. On the basis of the image data, the controller controls the inkjet head to stop discharging ink, when the inkjet head is moved from the outside toward an end of the base material. The controller controls, when the inkjet head is moved from the inside toward the end of the base material, the inkjet head to discharge ink to complement an image in a section where the inkjet head stops discharging ink.
