摘要:
A printing apparatus using a print head of an inkjet-type, in which, if a splice is detected during printing, an area of a following part of a continuous sheet that follows the splice is used to perform image-quality adjustment such as color shading adjustment, an adjustment of a gap between the print head and a sheet, and a color registration adjustment of the print head.

In a printing system capable of selectively performing duplex printing and simplex printing, a first input unit and a second input unit are adjacent to each other. A first output unit and a second output unit are adjacent to each other. In duplex printing, a sheet supplied from the first input unit is printed on a first side thereof in a first printing apparatus and the traveling direction thereof is changed at a changing unit while the sheet is reversed, and then the sheet is printed on a second side thereof in a second printing apparatus and output to the second output unit. In simplex printing, a sheet supplied from the first or second input unit is printed on one side thereof and the traveling direction thereof is changed at the changing unit, and then the sheet is output to the first or second output unit.

In a printing system capable of selectively performing duplex printing and simplex printing, a switching unit switches a sheet travel path between a first path and a second path parallel to each other, and reverses the sides of a sheet that passes along the first path. In the duplex printing, a sheet is printed on a first side by a first printing apparatus, reversed by the switching unit, and printed on a second side reverse of the first side by a second printing apparatus. In the simplex printing, only one side of a sheet is printed by the first printing apparatus and/or second printing apparatus. First and second input units introduce sheets into the first and second paths, respectively; and first and second output units receive printed sheets that have traveled along the first and/or second paths.

Provided is a recording apparatus which is advantageous in miniaturization even when a mechanism for adjusting a head gap is included. The recording apparatus includes a carriage for detachably holding a cartridge, a platen for supporting one surface of a recording medium, and a conveying roller and an eject roller for conveying the recording medium. The platen is constructed so that it is rockable with an axis of the eject roller as a rotation center and is switchable between at least two positions.

An inkjet recording device including a tank incorporated inside an inkjet recording head and divided into a large-capacity main chamber and first and second vertically-arranged needle-receiving chambers. Each needle-receiving chamber includes a connecting hole for communication with the main chamber and an opening for receiving a needle. First and second needles that pass through corresponding first and second resilient joints that seal the opening are inserted into the corresponding first and second needle-receiving chambers. The upper first needle is connected to a pump for discharging air through a first tube, and the lower second needle is connected to a main tank for supplying ink through a second tube. In each needle-receiving chamber, the connecting hole is positioned above the opening, and/or the connecting hole is made small. When the connecting hole is above the opening, the inkjet recording device reduces the tendency of ink to solidify near holes of the needles used to supply ink. When the connecting hole is small, an ink meniscus is formed in the connecting hole, which likewise reduces the tendency of the ink to solidify.

A liquid discharge head unit is positioned in high precision when mounted on the carriage of a liquid discharge recording apparatus. For the liquid discharge head unit, a side extrusion formed in column, which is rotatively supported in carriage, presses the upper surface of guide ribs formed on both side ends on the upper rear portion. This upper surface is made higher toward the rear side in order to effectuate the substantially horizontal movement of the pressurized position from the front side to the rear side. Then, the liquid discharge head unit is rotated around the side extrusion formed in column so as to be mounted on the carriage smoothly. Lastly, a guide pin, a rear extrusion, and a lower extrusion are allowed to abut against the corresponding portions of the carriage by means of pressure exerted on a receiving rib in order to perform positioning in the front, rear, left, right, up and down directions exactly. Also, by means of pressure exerted on the side face, the side extrusion is allowed to abut against the corresponding portion of the carriage to position the circumference of the guide pin in the rotational direction.

An ink jet recording apparatus is provided with a recording function to record images on a sheet material by installing an ink jet recording head that discharges ink from the ink discharge ports, and also, with an image reading function to read images from a sheet material by installing an image reading head exchangeably. This apparatus includes the discharge port surface of the ink jet recording head having the ink discharge ports formed on it, the image reading surface of the image reading head to read images to this head from the image reading surface, and a member that abuts upon the ink discharge port surface arranged to be in contact with the ink discharge port surface of the ink jet recording head. This member is arranged so as not to be in contact with the image reading surface of the image reading head. Thus the image reading surface of the image reading head is prevented from being stained by ink. Also, this apparatus can be made smaller with a simple structure to provide both reading and recording functions.

A skew feed or damage in the sheet in automatic feeding is avoided. In an image forming apparatus provided with a printer for recording an image, the printer is provided with a feeding port for enabling manual insert sheet feeding and an automatic sheet feeder (ASF) is detachably mounted on the feeding port to enable automatic sheet feeding through the feeding port. As shown in the drawings, the printer is provided with a printer sheet guide for manual insert sheet feeding, while the ASF is provided with an ASF sheet guide for automatic sheet feeding, and the ASF sheet guide is displaced toward the inner side of the sheet by a predetermined amount with respect to the printer sheet guide. Thus, the sheet automatically fed utilizing the ASF sheet guide does not contact the printer sheet guide, whereby the skew feed of the sheet and the damage to the sheet end can be prevented.
