Publication number: 20210070039Abstract: A droplet discharge apparatus discharges a droplet to form an image on a recording medium while being moved by a user. The droplet discharge apparatus includes ahead to discharge a droplet on a recording medium according to image data, a sensor to detect a movement amount of the droplet discharge apparatus in a predetermined period, and a processor. The processor is configured to instruct droplet discharge based on the image data and the movement amount detected by the sensor, determine floating of the droplet discharge apparatus from the recording medium based on information from the sensor, and stop the droplet discharge in response to a determination that the droplet discharge apparatus is floating.Type: ApplicationFiled: November 18, 2020Publication date: March 11, 2021Applicant: Ricoh Company, Ltd.Inventors: Hideaki IIJIMA, Tetsuyoshi NAKATA, Jun WATANABE, Yasunari HARADA, Toshiaki HOSOKAWA, Shunsuke SHITAOKA

Patent number: 10744787Abstract: A liquid droplet discharging apparatus includes a plurality of nozzles to discharge a liquid droplet onto a medium and a liquid droplet discharging controller to receive image data. The liquid droplet discharging controller controls each of the nozzles to discharge the liquid droplet in an amount defined by the image data onto a target discharging position on the medium, which corresponds to a pixel position defined by the image data. The liquid droplet discharging controller controls at least one of the nozzles to discharge the liquid droplet for a controlled number of times smaller than a number of times N representing an integer not smaller than 2 in an amount greater than the amount defined by the image data onto the target discharging position on the medium. A frequency recorder records the controlled number of times of discharging for each of the at least one of the nozzles.Type: GrantFiled: February 26, 2018Date of Patent: August 18, 2020Assignee: RICOH COMPANY, LTD.Inventors: Yasunari Harada, Jun Watanabe, Tetsuyoshi Nakata, Hideaki Iijima, Toshiaki Hosokawa, Shunsuke Shitaoka

Patent number: 10479105Abstract: A droplet discharge apparatus to discharge droplets while moved by a user includes a head to discharge a droplet onto a recording medium, a sensor to detect a movement amount of the droplet discharge apparatus in a predetermined period, and a memory to store determination information indicating whether droplet discharging has been instructed for each pixel of the image data. The droplet discharge apparatus further includes a processor configured to accumulate the movement amount to calculate a total movement amount of the droplet discharge apparatus; instruct droplet discharging from the head based on the total movement amount and the image data; instruct droplet discharging only for an unprinted pixel for which the determination information indicates that droplet discharging has not been instructed; and rewrite the determination information of the unprinted pixel to indicate that droplet discharging has been instructed, based on a predetermined condition.Type: GrantFiled: August 14, 2018Date of Patent: November 19, 2019Assignee: RICOH COMPANY, LTD.Inventors: Toshiaki Hosokawa, Jun Watanabe, Tetsuyoshi Nakata, Yasunari Harada, Hideaki Iijima, Shunsuke Shitaoka
