Patent number: 6804032Abstract: An image recording device includes a standby device and a retracting device. Before processing for recording an image on a photosensitive material is implemented, the standby device conveys a leading edge of the photosensitive material to a standby position at a curved region on a conveyance path, with the curved region having a relatively small radius of curvature, whereby the photosensitive material is made to stand by. Before the leading edge of the photosensitive material is able to retain the curved shape of the curved region of the conveyance path and cause the photosensitive material to become jammed in the image recording device during conveyance, the retracting device moves the leading edge of the photosensitive material to a retraction position, where the leading edge is disposed along a linear region of the conveyance path or along a curve on the conveyance path that has a relatively large radius of curvature.Type: GrantFiled: March 11, 2002Date of Patent: October 12, 2004Assignee: Fuji Photo Film Co., Ltd.Inventor: Takehisa Ohno

Patent number: 6490024Abstract: An image forming device in which a plurality of image frames are exposed onto a photosensitive material at an exposure device, and the photosensitive material is superposed with image receiving materials of same sizes as the image frames on a heat drum, such that a plurality of image frames can be heat transferred all at once onto the image receiving materials. Image receiving materials of different sizes are readied in a plurality of magazines, and an image receiving material (magazine) of an appropriate size is selected in accordance with an exposure pattern and sizes of the image frames. Various types of prints can be formed by merely setting one photosensitive material. Further, because the plurality of image frames are heat transferred onto the image receiving materials all at once, printing processing efficiency can be improved.Type: GrantFiled: November 7, 2000Date of Patent: December 3, 2002Assignee: Fuji Photo Film Co., Ltd.Inventor: Takehisa Ohno

Photographic film loading method, photographic film conveying apparatus, and image reading apparatus
Patent number: 5880819Abstract: A photographic film loading method of loading photographic film at an apparatus which has a carrier for holding and conveying the film along a conveying path and which effects photometry of each frame image of the film at a predetermined position of the conveying path, comprising the steps of: spanning the photographic film between a supply reel and a winding reel; the carrier having a first portion disposed so as to be fixed at the apparatus and a second portion movable between a first position, at which the photographic film located on the conveying path is held between the first portion and the second portion, and a second position, which is withdrawn from the first position such that release of the holding of the photographic film between the first portion and the second portion is permitted, drawing-out an intermediate portion of the photographic film between the supply reel and the winding reel while the second portion is located at the second position, so as to locate the intermediate portion on the coType: GrantFiled: June 26, 1996Date of Patent: March 9, 1999Assignee: Fuji Photo Film Co., Ltd.Inventors: Shigeru Tanaka, Takehisa Ohno -
Patent number: 5639039Abstract: A winding device includes: a winding core capable of taking up an elongated photosensitive material; a guide member for forming a guide passage for the photosensitive material between the guide member and an outer peripheral surface of the winding core in a state in which the guide member is wound around the winding core; a guide arm which is rotated to allow a distal end thereof to be brought into contact with the winding core and adapted to guide the photosensitive material and the guide member along the guide arm from a proximal end side toward a distal end side of the guide arm; and a guide-member accommodating portion which is rotatively driven to pay out the guide member so as to cause the guide member to be wound around the winding core.Type: GrantFiled: January 5, 1996Date of Patent: June 17, 1997Assignee: Fuji Photo Film Co., Ltd.Inventors: Takehisa Ohno, Shigeru Tanaka
