Abstract: An image display unit and a method of detecting an object which are capable of reliably detecting an object with a simple structure irrespective of use conditions are provided. Invisible light is emitted from a screen of a display portion. The invisible light reflected from a target object which comes in contact with or close to the screen is received on the screen. On the basis of the received invisible light, the target object is detected. Thus, the target object can be reliably detected without influence of the display state of the display portion, and influence of use conditions such as surrounding circumstances (the case where it is bright or dark). Moreover, for example, it is not necessary to separately arrange a component such as a touch panel, so the image display unit can be achieved with a simple structure.

Abstract: A display device and a display method are provided in which the influence of the outside light can be removed easily, in the case where light-emitting and light-receiving are performed in parallel and simultaneously. In the case where an image-display and a light-receiving are performed simultaneously or alternately on a display surface of the display device, processing of making the display surface emit light to display an image is performed; light entering the display surface is received, which is the light-receiving of two times of a state in which the light-emitting for display use is being performed (step S11) and of a state in which light is not emitted (step S12); and a state in which the display surface is touched or approached is detected based on the detection of a difference in the quantities of received light of the two times (step S13).

Abstract: An information management apparatus generates an authentication image based on information registered by a user, and issues the authentication image to an information processing terminal owned by the user. When the user purchases a commodity in a store and shows the authentication image, the information processing terminal transfers the authentication image to a retailer terminal. The retailer terminal requests the information management apparatus to authenticate the authentication image. If the information management apparatus verifies that the authentication image is authentic, the information management apparatus generates a new authentication image instead of the authentication image displayed on the information processing terminal. The new authentication image is then sent through the retailer terminal to the information processing terminal. The present invention is applicable to an apparatus that is used when the user requires to identify himself.

Abstract: A method for interchangeably using a first and second type of disc cartridge. The first type of disc cartridge has a shutter suitable for being made from bent sheet metal. The second type of disc cartridge has a shutter suitable for being made from synthetic material, such as a synthetic resin.

Abstract: An optical disc includes a disc base plate of a light-transmitting synthetic material having a recess for mounting a magnetic plate, and a holding part, integral with the disc base plate, for loosely holding the magnetic plate mounted in the recess with respect to the disc base plate. It is possible with the present optical disc to prevent distortion of the disc base plate otherwise caused by the difference in thermal expansion coefficients of the two components to inhibit double refraction of the disc base plate otherwise caused by such distortion to maintain good recording/reproducing characteristics.
