Patent number: 6536967Abstract: The present invention detects print data areas set in one-block units with white lines as boundaries, calculates division numbers for divisionally driving a line head every areas extending in its main scan direction to thereby output print data when the numbers of dots set every lines in the print data areas exceed the maximum number of printable dots set by a head drive unit, detects maximum division numbers n in the print data areas, sets paper feed velocities V1 through V4 in inverse proportion to the maximum division numbers n respectively, and executes printing in the print data areas set in the one-block units on the condition that the line head is divisionally driven with the maximum division numbers n and paper is fed at the set paper feed velocities V1 through V4. Thus, a reduction in power consumption can be satisfied. Since it is possible to increase a paper feed velocity in proportion as a print data area low in the number of dots in particular, the speeding up of printing can be achieved.Type: GrantFiled: September 10, 2001Date of Patent: March 25, 2003Assignee: Toshiba TEC Kabushiki KaishaInventor: Yoshimasa Inoue

Patent number: 6533477Abstract: There is disclosed a thermosensitive line printer, wherein a heating element array of a thermal head is pressed on a thermosensitive recording paper at a distance L2 from a nipping position by a pair of conveyer rollers, and is driven to record an image frame line by line from a print starting end, as the recording paper is conveyed by the conveyer rollers in a direction from the thermal head to the conveyer rollers. Based on image data of an upper zone of an image frame that is to be recorded around the distance L2 from the print starting end if the image frame is recorded from its top side, an image analyzer calculates a first estimation value that represents conspicuousness of potential density deviation in the upper zone that could be caused by a thermal deformation of the thermosensitive recording paper at the print starting end if the image frame is recorded from the top side.Type: GrantFiled: February 5, 2001Date of Patent: March 18, 2003Assignee: Fuji Photo Film Co., Ltd.Inventor: Hiroshi Fukuda

Patent number: 6467895Abstract: Media is transported to an imaging region using a vacuum feeder. A vacuum head is positioned onto the media and a vacuum is applied to the vacuum head to hold the media against the vacuum head. The vacuum head is then relocated to the imaging region carrying with it the media. In one embodiment, the vacuum head holds the media slightly above the surface of the imaging region. After the media is imaged, the vacuum head moves the media to an output region. In the output region the vacuum is removed from the vacuum head allowing the media to detach from the vacuum head and remain in the output region. In another embodiment, the vacuum is removed from the vacuum head allowing the media to detach from the vacuum head and remain in the imaging region. A second vacuum head is positioned in the imaging region onto the media and a vacuum is applied to the second vacuum head to hold the media against the second vacuum head. The second vacuum head is then relocated to the output region carrying with it the media.Type: GrantFiled: February 16, 2000Date of Patent: October 22, 2002Assignee: Hewlett-Packard CompanyInventors: Roland John Burns, David D Bohn
