In a recording apparatus employing a magnetic linear encoder that includes a magnetized scale and a magnetic head movable along the scale, in order to enable efficient mounting of the scale on the recording apparatus and to enable tension adjustment of the scale, support members are provided for detachably supporting the scale, as is a device for providing tension during the mounting of the scale on side plates of the recording apparatus. Also, the magnetized portion of the scale is positioned behind the carriage. Further, the magnetic head is provided with dust shield members which are in contact with, but rendered slidable with respect to, the scale.

A recording apparatus, which is provided with a carriage supporting a recording head or reciprocating along a platen, includes a magnetized scale of a magnetic linear encoder positioned along a moving direction of the carriage, and a magnetic head of the magnetic linear encoder, mounted on the carriage and adapted for reading the magnetized pattern of the scale. The scale is provided with at least two magnetized lines of mutually different pitches of magnetization, for recording position information relating to the recording operation, and position information relating to other functions.

A recording head has a plurality of recording elements which are divided into a plurality of blocks and each block is driven in a time division fashion. The recording head has a signal generation circuit for generating an output signal for selecting a drive block in response to an input signal for designating the drive block from a main body of a recording apparatus. The number of signal lines of the input signal is smaller than the number of signal lines of an output signal. One such recording head is provided for each of a plurality of colors to record a color image. Signal lines of an input signal are common to the respective recording heads. Thus, the number of signal lines between the recording heads and the main body of the recording apparatus is reduced and cost reduction and space saving are attained.

A recording apparatus records an image on a recording medium by scanning by a recording head. Mask data for masking record data is set in registers, a record timing signal synchronized with the scan of the recording head is counted up by a counter, and the mask data set in the registers is selected by selectors in accordance with the count. The selected mask data is logically ANDed with the record data to drive the recording head. A load to software is reduced and the recording is attained while the record data is masked with a simple construction.

The present invention facilitates a supply of ink with a structural components at relatively low costs. It is performed by shifting a printing head having ink ejecting portion and sub tank portion into a state of reduced pressure. That is, draining ink from the sub tank portion to the outside and supplying ink from an ink storage container to the sub ink portion are performed by a reduced pressure in the printing head. Also, a carriage on which the printing head can be mounted shifts its position, and a plurality of ink receiving portions communicated with a plurality of their relative sub ink tank and a plurality of ink supplying portions communicated with a plurality of their relative main ink tanks are arranged in a predetermined manner. That is, the plurality of sub ink tanks and a plurality of main ink tanks are communicated together on a pair basis.

In a battery-driven system comprising an electronic apparatus as a main unit and a power supply unit which incorporates a battery (cells) and supplies source power for working the main unit, the present invention intends to achieve more efficient use of the battery. A discharge switch for turning on/off an output of the battery supplied to the side of the main unit is incorporated in the power supply unit. In response to turn-on of a switch provided on the main unit side or a signal from an MPU (control unit) on the main unit side, supply of the source power from the power supply unit to the main unit is controlled to turn on/off.

A pack integrally housing inks and printing media has an ink housing section 211 arranged so as to overlap part of a printing media housing section 210. The ink housing section 211 is configured to rotationally move around a rotational moving shaft 212e so as to be opened and closed relative to the printing media housing section 210. On the other hand, the printing media housing section 210 has an opening 215 formed in a lower part thereof and in which part of housed printing media appears, thereby enabling the pack to come into contact with a sheet feeding roller of the printer when the pack is installed in a printer. Additionally, while not installed in the printer, the pack is covered with the opening and closing ink housing section 211, thereby enabling the printing media to be protected from dusts or the like.

A method of cleaning a discharge port surface of an ink jet recording apparatus includes wiping the surface using a blade having a certain contact area with the surface and rubbing the surface using a rubbing member having a larger contact area with the surface than the blade. The wiping and rubbing operations are performed independently of each other so that their different purposes can be better accomplished. For example, since rubbing the surface need not be done as often as wiping, they can both be performed at optimum intervals. The rubbing member can be removably mounted to a replacement ink cartridge so that the rubbing member can be conveniently replaced at the same time as the cartridge.

A part of the outer casing on the upper surface of a recording apparatus is arranged to be a cover capable of being opened and closed. When the recording apparatus is in operation (in use), the part of this outer casing becomes the sheet feeding tray which is open to stack recording sheets. The recording apparatus is provided with a linear antenna suitable for transmitting and receiving radio waves of ultra-short wave frequency band. The antenna is arranged on the right side of the recording apparatus, observed from the front side thereof, along the edge of the end portion of the cover that dually functions as the sheet feeding tray.
