Abstract: An actuator includes an attachment member including a coil; a movable element having a magnet disposed opposite to the coil, and that is displaced relative to the attachment member when the coil is energized; a resilient support; and a cushioning material. The resilient support has an attachment member-side fixing portion that is fixed to the attachment member, a movable element-side fixing portion that is fixed to the movable element, and a deformation portion that links the attachment member-side fixing portion and the movable element-side fixing portion. The cushioning material is provided between the attachment member and the deformation portion, and deforms in conjunction with bending deformation of the deformation portion.

Abstract: An indicator has an optical member including a protuberance formed on a front side and an indentation formed on a back side of the optical member in which the indentation is smaller than the protuberance in terms of a projection area and in which the front-side protuberance fits into the opening in a front face of the housing; and an LED light source disposed opposite the back-side indentation of the optical member. A center axis of the front-side protuberance and a center axis of the backs-side indentation are in line with an optical axis of the LED light source. Light originating from the LED light source passes through the back-side indentation and the front-side protuberance, exiting from the opening in the front face of the housing. Thereby, only the center of the rectangular opening looks lighting up brightly, rectangularly.

Abstract: An amplifier unit suitable for a wide variety of uses, which can flexibly support diverse sound recording scenarios, and a mobile electronic device provided with the amplifier unit. An amplifier unit has microphone/line input terminals respectively provided on the topside surface and the left side surface. When a connector is connected to a mobile electronic device, stereophonic sound is recorded using one of the terminals when the mobile electronic device is held in portrait orientation, and using the other terminal when the mobile electronic device is held in landscape orientation. It is possible to switch each of audio signals coming through the two terminals between monophonic and stereophonic.

Abstract: In a CD player, a connection tray is mounted in a cabinet in a shiftable manner among a retracted position, a first projected position, and a second projected position. The connection tray has an upper tray and a lower tray. The upper tray has a first connector, a second connector, and a stopper. The lower tray has an unlock button, a movable plate, and a lock plate. A lock bracket is formed with a lock depression into which a lock boss is inserted to lock the connection tray in the first projected position, in shifting the connection tray forward from the retracted position. In a front surface of the lock bracket, a lock projection is formed. The lock projection receives the lock boss to lock the connection tray in the second projected position.
