Abstract: A disclosed service providing system includes a server configured to deliver an image; and an image display terminal device configured to receive the image from the server via a communication network and display the image on a monitor. The server starts up and executes an application program at the server according to an operation made at the image display terminal device and sends, to the image display terminal device, the image obtained as a result of executing the application program. The image display terminal device displays the image received from the server on the monitor.

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face of the case body and selectively placed in one of a first position housed within the recess and a second position withdrawn from the recess to fix the image capturing range.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 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: Upon performing a recording/reproducing operation with respect to an optical disc at an operational speed higher than a standard operational speed, an operational rate is indicated by an operational rate indicator. Indication colors are changed according to the operational rate. Alternatively, a plurality of indicating elements are lighted according to the operational rate. Alternatively, characters, numerals, or symbols, etc., are displayed. Thereby, the operational speed (the operational rate) becomes easily visible from outside of the apparatus.

Abstract: A simplified optical disc writing apparatus that is connectable to a host system is provided in which at least one part of a digital signal processing portion (123, 124, 131, 132) is carried out in the host system (200) by using software (300). Picked up from a first optical disc (11) by a pickup (110), amplified by an RF amplifier (121), and binary coded by a binary coding circuit (122), a binary coded signal is supplied to the host system (200) through a host interface (210). The software (300) carries out a processing for EFM demodulating the binary coded signal, a processing for decoding the EFM demodulated signal, a processing for encoding user data, and a processing for EFM modulating the encoding processed signal. The EFM modulated signal is added with a strategy in a strategy adding circuit (133), and is converted into a laser driving signal in a laser driver (134). Responsive to the laser driving signal, the pickup (110) writes data in a second optical disc (12).

Abstract: A disc drive includes a disc drive main body having a playback or recording/playback mechanism of a disc and a disc tray which is constructed to support the disc thereon and is movable with respect to the disc drive main body between a disc eject position and a disc loaded position; and a motor provided in the disc drive main body for moving the disc tray, wherein the moving speed of the disc tray is variable by changing the number of rotations of the motor. The motor is driven by rectangular pulses from the motor driver, in which the number of rotations of the motor is varied by changing the on/off widths of the rectangular pulses so that the moving speed of the disc tray is reduced in a stepwise manner over the period from the start to the stop of the disc tray movement.

Abstract: A circuit module includes one or a plurality of semiconductor parts, a substrate having the semiconductor parts mounted thereon, and terminals arranged on an outer periphery of the substrate along a plurality of sides of said substrate. The circuit module is connected to a board of a computer by plugging the terminals into corresponding terminal holes, so that the terminals are used in common for providing electrical connection and mechanical connection with the board of the computer.
