Abstract: A mouse-type input device is adapted to be connected to a computer device to input coordinates information thereto. In the input device, an image capturing device is adapted to capture an image of an object arranged within an image capturing range, and a projector is adapted to project light so as to visualize at least a part of a contour of the image capturing range.

Abstract: A mouse device is adapted to be connected to an information processing device. A case body has a bottom face formed with a recess. A coordinates information input device is provided on the bottom face of the case body to input coordinate information to the information processing device. An image capturing device is incorporated in the case body to capture an image of an object situated within an image capturing range. A stand is integrally provided on the bottom face of the case body and selectively placed in one of a first position housed within the recess and a second position withdrawn from the recess to fix the image capturing range.

Abstract: A disk drive includes a disk tray for introducing a disk into a disk drive main body. The disk tray includes a disk mounting part. The disk mounting part includes a main part having a dimension compatible with the disk, extensions, and tongue parts. The extensions and the tongue parts latch a portion of the disk so as to support the disk in an upright position.

Abstract: A pickup driving system for an optical disk apparatus is disclosed for moving a pickup unit across tracks of a rotating optical disk to read data at a target track position on the optical disk while avoiding drive motor instability, and errors caused by position overruns and underruns. A pulse voltage is superposed on the driving voltage of the drive motor for driving the pickup unit at predetermined intervals (defined by the pulse train) toward the target track position.

Abstract: An optical disk driver using a top-loading mechanism is coupled to an operational processor, such as a personal computer. The term "a top-loading mechanism" means a mechanism for inserting and/or ejecting an optical disk via a top surface of the optical disk driver. Additionally, a display unit used for the operational processor can be located on an operational processing apparatus comprising such an optical disk driver and an operational processor.
