Patent number: 12158719Abstract: A sheet laminator includes a fuser pressure member, a conveyor, and a guide. The fuser pressure member thermally fixes a two-ply sheet and a sheet medium inserted between two sheets of the two-ply sheet. The conveyor conveys the two-ply sheet toward the fuser pressure member in a sheet conveyance direction. The guide guides the two-ply sheet in a sheet conveyance passage between the conveyor and the fuser pressure member. At least one of the fuser pressure member or the conveyor is operable to guide the two-ply sheet outside the sheet conveyance passage in response to an occurrence of an abnormal stop of the sheet laminator.Type: GrantFiled: June 7, 2023Date of Patent: December 3, 2024Assignee: RICOH COMPANY, LTD.Inventors: Naoki Takai, Keisuke Sugiyama, Yuichiro Kato, Kazuki Shimodate, Shota Yoshida, Takaya Ochiai, Yosuke Saito

Publication number: 20240253341Abstract: A sheet processing system includes a sheet processing device and a lamination processing device. The sheet processing device includes a sheet separator that separates a two-ply sheet and inserts an inner sheet between the two-ply sheet to form a first enclosed two-ply sheet. The lamination processing device bonds the first enclosed two-ply sheet, and bonds a second enclosed two-ply sheet in which the inner sheet is inserted outside the sheet separator. The sheet processing system includes a relay conveyor that conveys the first enclosed two-ply sheet from the sheet separator to the lamination processing device attachable to a sheet feeder to directly feed the second enclosed two-ply sheet to the lamination processing device. The sheet processing device includes a cord holder to hold the power cord of the lamination processing device at a position where feeding and ejecting the two-ply sheet after bonding the two-ply sheet are not hindered.Type: ApplicationFiled: January 18, 2024Publication date: August 1, 2024Applicant: Ricoh Company, Ltd.Inventors: Kazuki SHIMODATE, Naoki TAKAI, Yuichiro KATO, Sho ASANO, Ruki MIDORIKAWA, Yosuke SAITO

Publication number: 20240239092Abstract: A lamination processing system includes a sheet separation device, a lamination fixing device, and a conveyor. The sheet separation device separates a two-ply sheet to insert a sheet medium between two sheets of the two-ply sheet to form an enclosed two-ply sheet. The lamination fixing device includes an inlet port and a heater. The conveyor conveys the enclosed two-ply sheet from the sheet separation device to the lamination fixing device in a conveyance direction. The conveyor includes a conveyance passage and a guide. The conveyance passage guides the enclosed two-ply sheet from the sheet separation device toward the lamination fixing device. The guide guides the enclosed two-ply sheet to the inlet port. The guide forms a space accommodatable a deflected part of the enclosed two-ply sheet formed by a difference in a conveyance speed of the enclosed two-ply sheet between the sheet separation device and the lamination fixing device.Type: ApplicationFiled: December 8, 2023Publication date: July 18, 2024Applicant: Ricoh Company, Ltd.Inventors: Yosuke SAITO, Yuichiro KATO, Sho ASANO, Ruki MIDORIKAWA, Naoki TAKAI, Kazuki SHIMODATE

Patent number: 7020883Abstract: A disk loading mechanism has a turntable. A turntable 36 itself is fixed in external dimensions of a brushless spindle motor, and a chucking face relevant to a disk 11 is precisely placed on a turntable base 46 with a predetermined height. On the turntable base 46, columns 47 are embedded in three directions on a circumference which surrounds the outer periphery of the turntable 36. A column tip end stepped portion 47b and a disk placement face 36a of the turntable 36 are precisely constructed in predetermined dimensions. When the column tip end stepped portion 47b abuts against a bottom face (a reference face L) of a drive board 15, a relative position between the disk placement face 36a of the turntable 36 and a pickup constructed while the bottom face of the drive board 15 is defined as a reference is precisely determined.Type: GrantFiled: September 26, 2001Date of Patent: March 28, 2006Assignee: Clarion Co., Ltd.Inventors: Kazuki Takai, Akira Takahashi, Yoshikazu Omura

Patent number: 6826765Abstract: A disk player compatible with two types of large and small diameter disks is provided. A startup arm 20 is transversely moved by a selection arm 50 turned by abutment of a side edge of a large diameter disk 14b. Then, the startup arm 20 turning together with a shift bar 17 moved to be pushed at the front edge of the disk 14b is longitudinally moved. A cam follower pin 25 is engagingly locked with a pocket 53c by a spring 24, and the startup arm 20 is constrained in cooperation with a swivel shaft 22, whereby the shift bar 17 is restricted, and the center of the large diameter disk is positioned. The small diameter disk 14a restricts the shift bar 17 by the startup arm 20 by which the cam follower pin 25 is engagingly locked with the pocket 43c by the spring 24 irrespective of the selection arm 50. The center of the small diameter disk is positioned at the same central position as that of the large diameter disk.Type: GrantFiled: March 25, 2003Date of Patent: November 30, 2004Assignee: Clarion Co., Ltd.Inventors: Kazuki Takai, Akira Takahashi, Yoshikazu Omura
