20090123197 | IMAGE FORMING APPARATUS - An image forming apparatus includes first and second image bearing members on which a toner images are to be formed; a conveying member onto which the toner images are to be transferred; a conveying member position index detecting device for detecting a conveying member position index provided on the conveying member along the movement direction of the conveying member; an image bearing member position index detecting device for detecting the image bearing member position indices provided on the second image bearing member along a rotational direction of the second image bearing member; an adjusting device for adjusting a rotational speed of the second image bearing member; a controller for controlling the adjusting device so as to adjust a position of an image bearing member position index correspondingly to the conveying member position index, on the basis of detection results of the conveying member position index detecting device and the image bearing member position index detecting device; and an initializing portion for performing an initializing operation of the adjusting device when an amount of deviation between the conveying member position index and the corresponding image bearing member position index is out of a predetermined range. | 05-14-2009 |
20090141063 | INKJET PRINTING HEAD AND INKJET PRINTING APPARATUS - A temperature rise of a head due to a printing operation with a higher speed and a higher density is suppressed. To realize this, an inkjet printing head is provided in which a plurality of printing element substrates having an ejection opening array consisting of a plurality of ejection openings for ejecting ink are arranged on a support plate in a direction of the ejection opening array. The support plate includes therein a heat pipe and a flow path through which cooling liquid is flowed. | 06-04-2009 |
20090141064 | INK JET RECORDING HEAD AND INK JET RECORDING APPARATUS - An ink jet recording head includes a flow passage for a liquid for cooling a recording element substrate. The flow passage is provided inside a support plate that supports the recording element substrate along a recording element array of the recording element substrate. The shortest distance between a recording element and the flow passage at the end of the support plate is larger than the shortest distance between a recording element and the flow passage in the middle of the support plate. | 06-04-2009 |
20100226696 | IMAGE FORMING APPARATUS - The image forming apparatus includes a plurality of photosensitive members, a plurality of exposure portions to perform exposure on the plurality of photosensitive members, a development portion to form a toner image at the plurality of photosensitive members, a transfer medium to which the respective toner images formed on the plurality of photosensitive members are sequentially transferred so as to form an image, and a position correction portion to perform position correction by moving at least one photosensitive member among the plurality of photosensitive members, and the position correction of the photosensitive member is performed by swinging the photosensitive member by the position correction portion having a line on a circumference surface of the photosensitive member corresponding to an exposure position of the exposure portion as the center axis. | 09-09-2010 |
20120154912 | CORRECTION OPTICAL DEVICE - A correction optical device includes a rotating member that is disposed between a fixed member and a movable member that supports a compensation lens. By controlling rotation of the rotating member using the movable member, the movable member is locked and unlocked. | 06-21-2012 |
20130076922 | CORRECTING OPTICAL DEVICE AND IMAGE PICKUP APPARATUS - A correcting optical device according to an aspect of the present invention in which, when image shake is not corrected, a restricting member is caused to engage an engaging portion, to restrict translational movement of a movable member, and in which, when the image shake is corrected, the restricting member is caused to disengage the engaging portion, to cause the movable member to be in a state capable of the translational movement, the restricting member being provided at the rotary member, the engaging portion being provided at the movable member. A driving unit drives the movable member in a direction in which the movable member moves translationally with respect to a fixed member in a plane perpendicular to an optical axis of a correcting lens, so that the correcting lens corrects the image shake, and drives the rotary member in a direction in which the rotary member rotates around the optical axis. | 03-28-2013 |
20140160566 | CORRECTION OPTICAL APPARATUS, IMAGE BLUR CORRECTION APPARATUS, AND IMAGE CAPTURING APPARATUS - A correction optical apparatus configured to correct an image blur includes a rotating member rotatably supported, a sliding member movable in a first direction, a movable member configured to be movable in a second direction and support a correction lens, a first driving unit provided between the rotating member and the sliding member, and a second driving unit provided between the sliding member and the movable member. The image blur is corrected by driving of the first and second driving units. When the image blur correction is not to be performed, a regulating member provided on the rotating member is made to engage with an engaging portion provided on the movable member by driving of the first driving unit, thereby regulating translation of the movable member. | 06-12-2014 |
