  • Publication number: 20030077098
    Abstract: An IC memory module 33 for storing paper-related information is embedded in a core 31 of a roll paper member 30. A control circuit 50 accesses the IC memory module 33 embedded in the core 31 of roll paper member 30 via a transmission-reception antenna 202 at a timing, for example, when a power source is turned on, the roll paper member 30 is replaced, and power source is turned off, and acquires the paper-related information. The control circuit 50 controls the printing processing by taking account of the information acquired from the IC memory module 33.

  • Patent number: 6431674
    Abstract: An ink-jet recording apparatus having an ink-jet recording head including pressure generating chambers communicatively connected to a nozzle opening and a reservoir, pressure generating member for pressurizing the pressure generating chambers, and a control device for applying drive signals to the pressure generating member. The control device applies drive signals to the pressure generating member. The drive signals contain signals corresponding to print data and signals which minutely vibrate the meniscus of ink in the nozzle openings to such an extent as to not eject ink droplets during a nonprint period. The control device causes ejection of ink droplets from the nozzle openings in accordance with print data during printing operations, and minutely vibrates the meniscuses of ink formed at the nozzle openings a preset period of time before or after the discharging of the ink droplets in a printing operation.

  • Patent number: 6331040
    Abstract: An apparatus for driving an ink jet record head, in which a pressure generating element and an opening is provided for each of a plurality of nozzles so as to cause an ink droplet to spout from the opening. The apparatus includes a driving signal generation unit that generates a driving signal, which includes a first driving pulse for causing a first ink droplet to spout from a nozzle and a second driving pulse for causing a second ink droplet to spout from the nozzle that is greater in size than the first ink droplet. Also included is a dot creation unit configured to select both the first driving pulse and the second driving pulse in one recording period corresponding to the recording of one pixel so as to create a larger dot than dots formed by the first and second ink droplets, and an element driving unit that drives the pressure generating element in response to the selected driving pulses.

  • Patent number: 6106113
    Abstract: In a transfer type ink jet recording system, a scanning is conducted on a transfer drum using a recording head to form ink dot strings. The recording head is moved in one subscanning direction with a fixed pitch so that ink drops are impacted to positions which are not adjacent to ink dot strings formed immediately before the current scanning step, whereby a repellent phenomenon is prevented from occurring. According to another aspect of the invention, the printing sequence is changed in accordance with the density of print data. A dot counter counts the number of printing dots of each of a plurality of writing blocks in a video memory. A controller decides the sequence of printing the printing blocks on the basis of the result, and transfers information indicative of the sequence of the printing blocks to a memory selector. In deciding the sequence, restriction is set so that adjacent blocks are not successively subjected to the printing step.

  • Patent number: 6070959
    Abstract: The recording device of an ink jet type comprises a drive voltage generation circuit which, in synchronization with a timing signal given from outside, generates a first drive voltage having a trapezoidal wave form, a drive circuit which outputs a first drive voltage to a piezo-vibrator in accordance with a printing signal given from outside and also, in synchronization with the timing signal, outputs a second drive voltage, which is used to generate such a small pulse that cannot jet out ink drops from a nozzle opening, to the piezo-vibrator in which a non-printing condition has continued for one or more cycles, and control means which stops the application of the small pulse when the time of application of the small pulse after completion of a printing operation exceeds a given time.

  • Patent number: 5005043
    Abstract: An image forming apparatus includes a photosensitive medium having light sensitive microcapsules thereon which are pressed against a transfer medium to transfer a latent image from the photosensitive medium to the transfer medium. A pressure developing device is employed which generates a load only during that period when the image is being developed on the receiving medium. The photosensitive medium is contained in a detachable container. A thermal treatment mechanism fixes the images formed on the receiving medium and imparts a glossy finish. An illuminating mechanism illuminates directly or indirectly the photosensitive medium. An exposure mechanism subjects a first predetermined region of the photosensitive medium to light representative of the image and a second predetermined region of the photosensitive medium to light nonrepresentative of the image. The exposure mechanism also subjects the first predetermined region of the photosensitive medium to light having a uniform intensity.

  • Patent number: 4945383
    Abstract: An image forming apparatus includes a temperature control device for controlling the temperature of light sensitive microcapsules on a photosensitive medium which are pressed against a transfer medium to transfer a latent image from the photosensitive medium to the transfer medium. A pressure developing device is employed which generates a load only during that period when the image is being developed on the receiving medium. The temperature control device range prevents the ambient temperature from adversely affecting the light sensitive microcapsules prior to exposure to light.
