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.

A scanner head cartridge, which can be mounted exchangeably with an ink head cartridge on a carriage capable of moving the ink head cartridge of an information processing apparatus for recording on a recording medium, includes a lower case containing therein optical parts required for reading, an upper case structured to be coupled with the lower case for covering the open face of the lower case and guiding means arranged on the upper surface of the upper case for positioning when being inserted into the carriage. With the structure thus arranged, it is possible to mount the scanner head cartridge on the carriage by a simple mounting operation with a highly precise positioning simultaneously.

A reading unit provided with an optical system mounted on a recording apparatus to read a source document includes a housing having the optical system in it, a light transmitting portion arranged on the outer surface of the housing of the reading unit in order to guide the light outside the reading unit into the optical system of the reading unit, and a protection member to cover the outer side of the light transmitting portion for opening and closing such portion freely. With the structure thus arranged, the reading unit is protected from ink mist and other particles created by the recording apparatus that may contaminate the reading unit, hence preventing the accuracy of reading signals from being lowered when reading is performed by means of this reading unit.

An inner-pressure-changing connecting portion that changes the inner pressure of an ink cartridge and a fitted portion to be fitted on a positioning mechanism provided on an ink-jet printer are disposed coaxially. In a configuration for supplying ink by applying pressure to a pressure chamber, high-accuracy positioning of the ink cartridge and the ink-jet printer can be achieved.

A multilayer film is produced by forming a first and a second layers consecutively on at least one surface of a biaxially stretched polyester base. The first layer contains particles and a binder both composed mainly of either tin oxide, indium oxide, zirconium oxide, or titanium oxide. When the refractive indexes of the base, the first layer, and the second layer are represented by η1, η2, and η3 respectively, the first layer and the second layer are adjusted for the refractive index such that the differences |η1−η2| and |η1−η3| are both not greater than 0.03. Adhesive strength is therefore kept high between the base and the layers to eliminate light interference, and the multilayer film offers an excellent optical property with few color rainbow effect.

For the sake of achieving both the size and weight reductions of a printing apparatus and increasing the reliability thereof, an ink tank is provided with a gas-permeable member that permits air to pass without permitting ink. The ink tank is capable of introducing ink through an ink inlet by negative pressure introduced in the ink tank through a common suction port.

An ink-jet printing apparatus, an ink-supplying apparatus, and a method for supplying ink are configured so that a mode of ink supply is changed to another mode, for example the mode of supplying ink to an ink tank is changed to another in accordance with a fact that a next page is intended to be printed or not, when an ink tank that requires the supply of ink is detected, with the result that the printing speed is increased.
