Abstract: 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.

Abstract: 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.

Abstract: A feeding apparatus, a printing apparatus and a feeding control method can simplify control software significantly on a printing apparatus side and can provide freedom of design in the feeding apparatus. A communication port is provided for communication between the feeding apparatus and the printer. The feeding apparatus performs paper feeding operation after receiving a paper feeding command from the printer. When a sheet is fed in the printer, a feeding operation completion signal is transmitted to the printer. On the other hand, rotation of a feeding roller is resumed at a slightly earlier timing than a rotation start timing of a transporting roller. Therefore, back tension on the sheet by the feeding roller is minimized, and positioning the top of the sheet by the transporting roller is enhanced reliably.

Abstract: 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.

Abstract: A scanner head cartridge is constituted by a lower case which houses optical parts required for reading and electrical parts required for image processing, and an upper case which can engage with the lower case to cover the open surface of the lower case, and a positioning guide means used upon inserting the cartridge into the carriage is formed on the surface of the upper case, that is opposite to the lower case. A scanner head cartridge is held on a carriage that moves an ink head cartridge of an ink-jet printer for performing recording on a recording medium, in place of the ink head cartridge, and can be commonly used using a common base unit even in carriages which mount different ink head cartridges and have different shapes. In addition, the scanner head cartridge allows easy adjustment of the optical system.
