Patent number: 7340751Abstract: A vehicle mount disc player having a small thickness by removing a wasteful space around a reproduction unit chassis when a disc is loaded or unloaded. The vehicle mount disc player has the reproduction unit chassis supported in a floating state by a main chassis via damper mechanisms. The reproduction unit chassis is locked so as to be shifted to a disc motor side along an axial direction of a disc motor and a turntable when the disc is loaded or unloaded.Type: GrantFiled: July 14, 2004Date of Patent: March 4, 2008Assignee: Kabushiki Kaisha KenwoodInventors: Takafumi Suwa, Shoji Tomioka, Tsutomu Imai, Yosuke Haga, Takeharu Sasada

Patent number: 6636470Abstract: A disc reproduction apparatus capable of stabilizing the position of the circumferential edge of a disc during the disc loading and preventing the disc from abutting on a turntable. In the disc reproduction apparatus of the type that a disc squeezed between a disc guide and a disc roller is loaded while the roller is rotated, a disc contact surface of the disc guide is slanted so that the disc is spaced from a turntable along a disc transport direction when the disc is loaded.Type: GrantFiled: February 11, 2000Date of Patent: October 21, 2003Assignee: Kabushiki Kaisha KenwoodInventors: Takeharu Sasada, Tsutomu Imai, Yosuke Haga, Shinji Masuda, Atuomi Ono, Midori Murakami

Patent number: 6614747Abstract: A floating chassis support mechanism is provided which can thin a disc reproduction apparatus. In the floating chassis support mechanism for a disc reproduction apparatus for supporting a floating chassis with springs and dampers vertically from the opposite side of a loaded disc, the damper is disposed outside of a projection area of the disc, and an area of the floating chassis supported by the dampers is retracted towards the disc side more than a lower surface of the disc.Type: GrantFiled: June 7, 2002Date of Patent: September 2, 2003Assignee: Kabushiki Kaisha KenwoodInventors: Tsutomu Imai, Yosuke Haga, Takeharu Sasada, Shinji Masuda, Atuomi Ono, Midori Murakami

Patent number: 6535476Abstract: A contact between a clamper holder and clamper and between the clamper holder and disc can be reliably prevented while the disc is rotated. A disc clamp mechanism for a disc apparatus for clamping or unclamping a disc by moving a clamper holding chassis near to or remote from a turntable, the clamper holding chassis holding a clamper with a clamper holder, wherein: a lever is rotatively supported by the clamper holding chassis and moved in cooperation with a motion of the clamper holding chassis; and a contact portion of the clamper holder with the clamper is displaced in a motion direction of the clamper holding chassis and a clamper radial direction relative to the clamper holding chassis, in cooperation with a motion of the lever relative to the clamper holding chassis.Type: GrantFiled: July 21, 2000Date of Patent: March 18, 2003Assignee: Kabushiki Kaisha KenwoodInventor: Yosuke Haga

Patent number: 6438095Abstract: A disc clamp mechanism for a disc apparatus is provided. In the disc clamp mechanism, a disc is clamped or unclamped by moving a clamper holding chassis near to or remote from a turntable, the clamper holding chassis holding a clamper with a clamper holder, and a contact portion of the clamper holder with the clamper is deformed relative to the clamper holding chassis along a motion direction of the clamper holding chassis. A large space can be formed between the clamper and a turntable in a disc unclamp state to prevent the disc from becoming in contact with the clamper or turntable and being damaged while the disc is transported. A stroke of the clamper holding chassis necessary for reserving the space is made small to make a disc apparatus compact.Type: GrantFiled: March 10, 2000Date of Patent: August 20, 2002Assignee: Kabushiki Kaisha KenwoodInventors: Yosuke Haga, Tsutomu Imai, Takeharu Sasada, Shinji Masuda, Atuomi Ono, Midori Murakami

Patent number: 5214552Abstract: An actuator for moving a recording head in a radial direction of a recording disc includes a first member and a second member. The first member has a first actuator body and a driving coil adhered to said first actuator body by a adhesive, and the second member has a second actuator body and a bearing mechanism which is provided to said second actuator body. The recording head is mounted on at least either said first actuator body or the second actuator body, and said first member and the second member pivot on said shaft which is fixed on a base and is engaged with said bearing mechanism of said second member due to an operation of said driving device of said first member so that the recording head is moved in the radial direction of said recording disc. In the production of the actuator, the first member and the second member separately produced and then the first member and second member integrated with each other.Type: GrantFiled: January 15, 1991Date of Patent: May 25, 1993Assignee: Teac CorporationInventor: Yosuke Haga

Patent number: 5130895Abstract: An apparatus having a rotary member rotatable around a shaft mounted on a base and to which a flexible printed circuit board is attached. The flexible printed circuit board is attached to the rotary member at an end thereof, and is fixed via the base at the other end thereof. The flexible printed circuit board has a bent portion between both ends thereof. The bent portion of the flexible printed circuit board is pushed by a pushing member which is mounted on the base so that the direction of an elastic force exerted by the bending of the flexible printed circuit board against the rotary member coincides approximately to the center axis of the shaft irrespective of the position of the rotary member. As a result of that a moment around the shaft, caused by the elastic force, to which moment the rotary member is subjected, is approximately zero.Type: GrantFiled: October 31, 1990Date of Patent: July 14, 1992Assignee: TEAC CorporationInventors: Masayuki Somemiya, Yosuke Haga

Patent number: 5080252Abstract: A sealing apparatus for sealing a magnetic disk drive. The sealing apparatus includes a base member on which heat generating parts are mounted, a sealing member provided on and adhering to a circumferential edge of the base member, and a lid member secured to the base member via the sealing member for covering an internal space enclosed with the base member and the lid member. The lid member has a downwardly extending peripheral portion which comes in contact with the sealing member, and is arranged on the sealing member such that the downwardly extending peripheral portion is placed substantially on a centerline of the sealing member lying in the middle of a width of the circumferential edge of the base member.Type: GrantFiled: January 15, 1991Date of Patent: January 14, 1992Assignee: TEAC CorporationInventor: Yosuke Haga
