A head-up display makes an observer visually recognize an image, which is optically reflected by a combiner, as a virtual image. The head-up display has a main body unit and an attaching unit. The main unit has a light source which is a projection unit for projecting the image. The attachment unit is configured such that the attachment unit can be attached to a sun visor that is provided to a vehicle. The joint member has a rotation shaft that rotatably joints the main unit to the attachment unit. The damper reduces vibration of the main unit in the rotational direction of the rotation shaft. When the rotation shaft of the joint member is attached to the sun visor by the attachment unit, the rotation shaft is substantially parallel to a sun visor supporting shaft so the sun visor can rotate in the direction in which the sun visor opens/closes.

Virtual image display device and attachment device

A support () that is substantially cylindrical so as to be received by a disk hole (NA) and has a positioning portion () on a circumference adjacent to a first axial end is provided with a concave portion () of which both ends open to the circumference along a radial direction. A first engaging portion () protrudes from around the circumference at which a first axial end of the concave portion opens substantially opposes to the positioning portion with a gap equal to or more than a thickness of an optical disk (N). A moving member () is disposed in the concave portion in a manner movable along a radial direction of the support. A second engaging portion () protrudes on an end of the moving member at a position corresponding to a second axial end of the concave portion.

Holding device and disk device for recording and reading information

A connecting-side connector is connected to a receiving-side connector. A main frame supports the receiving-side connector in such a manner that the receiving-side connector is movable in a connection direction. A control unit performs a control of a movement of the receiving-side connector in the connection direction and a release of the control each time a pressing force is applied to the connecting-side connector in the connection direction.

Connector device and electronic device

A disc transfer section for transferring an optical disc by guide members and a transfer roller is disposed adjacent to an opening of a casing. A detectorfor detecting the optical disc is disposed adjacent to the opening. When unloading the optical disc, the peripheral edge of the optical disc contacts with slide members so that the slide members are slid, thereby sensor switches SWto SWare appropriately switched on and off. Based on a time difference between the timings of the on/off switchings, the relation between a movement trajectory of the center of the optical disc and an axis of symmetry that is a straight line indicating a transfer direction at the center of the opening is judged in order to control the drive of a transfer motor according to the movement trajectory. The amount of advancement when the unloading is completed is kept constant.

A transport unitincludes a holding sectionA that holds a discand a transport sectionB that transports the disc. Since the discis held by the holding sectionA when the discis transported, the discis prevented from being disengaged from the transport sectionB, so that a transport distance of the disccan be lengthened.

Disk-like recording medium conveyance device

A main frame supports a receiving-side connector to which a connecting-side connector is connected in movable manner toward inside. A holding unit holds the receiving-side connector that is moved to the inside. A connector biasing unit applies a biasing force toward outside to the receiving-side connector. A hold releasing unit releases a hold by the holding unit, and moves the receiving-side connector to the outside by the biasing force. A pressing-force applying unit applies, when the receiving-side connector is not moved by the biasing force, a pressing force for ejecting the receiving-side connector to the receiving-side connector.

Connector storing apparatus and electronic device

Provided is a disk carrying mechanism, in which a guide member () is installed on a disk guide block () and the disk guide block () with the guide member () being disposed on an opposite side of a roller () with a carrying route therebetween. The guide member () is formed as a ridge extending in a direction orthogonal to a direction of a carrying route and inclined from a center part to a peripheral edge part of a disk so that its height can be increased.

A stepping motor driving system includes: a stepping motor that rotates at a predetermined angle according to a driving pulse signal, a vibration detector that detects vibration to output a vibration signal, and a stepping motor control unit that controls the driving pulse signal, which is applied to the stepping motor, to rotate the stepping motor at the predetermined angle. The driving pulse signal includes a start-up current which is required for rotating the stepping motor at a unit angle and a holding current which maintains a rotational angle of the stepping motor rotated by the start-up current. The stepping motor control unit changes the level of the holding current according to the vibration signal which is outputted from the vibration detector.

An urging structure for an output shaft of a drive motor of the invention is configured by a pressing platewhich abuts against an end faceof an output shaft, and an urging springwhich urges the pressing plate in the axial direction of the output shaft. In the pressing plate, a fixing portionin one end is fixed onto a chassisin the vicinity of the output shaft, and an abutting portionis disposed on the tip end of a flexible arm portion. A spring holding portionwith which an end portion of the urging springthat is fixed to a spring bossis to be engaged is disposed on the rear face of the abutting portion

Urging structure for an output shaft of a drive motor

A playback mechanism of a recording medium is provided, by which a period of time required until information recorded in the recording medium is read out after the recording medium is inserted in an instrument body can be shortened and the size of the playback mechanism can be reduced. The mechanism includes an instrument body, conveying unit having a roller arm and disc guide, clamp playback unit having a locking pin, and locking member. The clamp playback unit is movable relatively to the instrument body. The locking member locks the locking pin to fix the clamp playback unit. The locking member releases the locking of the locking pin to make the clamp playback unit movable relatively to the instrument body. When the clamp playback unit clamps a CD, the roller arm and disc guide part from the CD, thereby the locking by the locking member is gradually released.
