An ink jet printer is of a small size and is capable of printing high-quality images, wherein an ink with a colorant dispersed in a solvent is ejected in a direction lower than a horizontal level and is adhered to a surface of a recording medium. The recording medium is conveyed while being spaced a constant distance from ink ejecting electrodes, thereby stabilizing an electric field induced between the ink ejecting electrodes and the recording medium and stabilizing the amount of the ink ejected.

A production device to produce an organic EL display includes a solution in which a light emitting material is dissolved, and a flying electrode to receive solution from the container. A voltage is applied between the tip of the flying electrode and an electrically conductive material of an organic EL substrate to form an electrostatic field, and the tip of the flying electrode and the organic EL substrate are shifted relative to one another in at least one of a perpendicular direction and a horizontal direction. With this arrangement, the solution is formed into a stringy beam from the tip of the flying electrode to it fly onto the organic EL, substrate, thereby injecting the solution into a concavity formed and surrounded by banks on the organic EL substrate, and forming red, green and blue light emitting layers.

A device for producing a color filter includes a part for storing a solution in which a light transmitting material is dissolved, a part for feeding the solution to a tip of a flying electrode, a part for applying a voltage between the tip of the flying electrode and an electro-conductive material of a color filter substrate so as to form an electrostatic field, and a part for relatively shifting the tip of the flying electrode and the color filter substrate with respect to one another in at least one of a perpendicular direction and to a horizontal direction. The solution is formed into a stringy beam which is let to fly onto the color filter substrate so that the solution is injected into a concavity formed and surrounded by a black matrix on the color filter substrate, arid forms red, green and blue light emitting layers.

An ink jet recording apparatus has a head substrate, a jetting member disposed on the substrate, a recording electrode disposed so as to sandwich the jetting member and for making ink jet from the jetting member, and a separating wall for covering the recording electrode, wherein the ink is supplied from the proximal end of the jetting member and recovered in an upward direction from near the tip end of the jetting member. According to such an arrangement, it becomes possible to prevent the recording electrode from being clogged with ink adhering at the tip end thereof, and thus, the locus of the ink drop jetted from the head can be prevented from being deviated due to deviation of the jetting point on the jetting member. Accordingly, it becomes possible to provide an ink jet recording apparatus which is capable of printing an image with a high definition.

A picture recording apparatus laser beam printer wherein a cassette, accommodating paper for receiving a transferred image, is loaded or unloaded on a front side of a housing of the printer. The conveyance direction of the paper accommodated in the cassette is reversed so as to be supplied to a transfer section by a paper separation reversal guide section. The conveyance direction of the paper is further reversed so as to be discharged on a tray in manner such that a forward end of the paper is located on a front surface side and an image transfer surface of the paper is faced downwardly. A manual paper feeding section is provided on the front side of the housing. A major portion of the cassette can be accommodated inside the housing whereby and the installation area can be reduced.

A motor for operating the door is controlled for forward and reverse rotations and stoppage by a control circuit responsive to an operation command signal, an upper-lower limit signal, an obstruction detection signal and a maximum drive time over signal, thus controlling the door stepwise for opening, stoppage, closing, stoppage and opening in that order. Upon generation of an obstruction detection signal or a maximum drive time over signal during the closing operation, the control circuit controls the motor in a manner to open the door for a certain period of time, and subsequently upon application of an operation command signal, the control circuit is set in a manner to open the door again.
摘要:
An ink jet recording head has a plurality of ink-discharge electrodes and control electrodes and an opposed electrode arranged at a fixed spacing and grounded. A pulse voltage with a reversed polarity is applied to the control electrodes in synchronization with the superimposition of the pulse voltage on a bias voltage applied to the ink-discharge electrode when the ink is discharged. As a result, an ink jet recording apparatus, which can decrease the pulse voltage needed to discharge the ink, is provided with a simple configuration.

A motor for driving a garage door is controlled by a control unit, which counts the time required for the garage door to move between an upper limit switch and a lower limit switch. The control unit sets a comparison reference time on the basis of the time thus counted, and controls the motor in such a manner that the motor driving does not continue for a period of time longer than the comparison reference time.

A high precision image recording apparatus includes an electrophotographic device having at least a photosensitive drum and an exposure unit, for forming a toner image on the surface of the photosensitive drum; a recording sheet feed/transport unit for feeding and transporting a recording sheet to which the toner image formed on the surface of the photosensitive drum is transferred; a transfer unit for transferring the toner image on the photosensitive drum to the recording sheet fed and transported by the recording sheet feed/transport unit; and a drive unit for driving the photosensitive drum and recording sheet feed/transport unit. The drive unit is provided with a motor coupled to the photosensitive drum via a rotation transmission mechanism having a speed reduction ratio of 1/integer number (inclusive of 1/1), and the exposure unit is provided with a recording start position control unit for starting recording image information from a predetermined reference position on the photosensitive drum.
