摘要:
An optical position detecting device includes: a plurality of detection light source sections which emits a detection light; a light source driving section which turns on a part of the plurality of detection light source sections in a first period, and turns on the other part thereof in a second period; a first light detecting section which detects the detection light reflected by a object; a second light detecting section which has a sensitivity peak in a wavelength band which is different from that of the first light detecting section and detects the detection light reflected by the object; and a position detecting section which detects the position of the object on the basis of the intensity of the detection light in the first light detecting section and the intensity of the detection light in the second light detecting section in the first and second periods.

An optical position detecting device includes: a plurality of detection light source sections which includes a first light emitting element which emits a first detection light and a second light emitting element which is turned on at a timing different from a timing when the first light emitting element is turned on and emits a second detection light having a peak wavelength different from that of the first detection light; a light source driving section which turns on a part of the plurality of detection light source sections, and turns on the other part thereof; a light detecting section which detects the first detection light and the second detection light reflected by a object; and a position detecting section which detects the position of the object on the basis of the intensity of the first detection light and the intensity of the second detection light in the light detecting section.

A detectable indication member for an optical position detection device includes a round bar shaped shaft and a spherical body provided at the distal end of the shaft. The outer peripheral surface of the spherical body and the outer peripheral surface of an end portion of the shaft portion connected to the spherical body form a retroreflective portion. A portion of the shaft adjacent the base end of the end portion absorbs infrared light.

摘要:
New functions are added to the existing telephone network to provide services of a telecommunications carrier which are intended to deter frauds and crimes committed using telephony. Also, the telephonic circumstances during the commitment of a fraud or crime are preserved to assist prevention of recommitment of a fraud or crime. A voice announcement indicating that a telephone conversation now started will be recorded is issued to a sender in advance. This offers a function that deters frauds and crimes by creating psychological resistance. A warning is issued to the recipient after performing a voiceprint check. The contents of telephone conversations during the commitment of a fraud or crime are played back to provide information necessary to take countermeasures against frauds and crimes.

An image processing apparatus includes an image processing unit configured to process an image; an input unit configured to input a start-up instruction to the image processing unit; a detection unit configured to detect that a first electric power is supplied in a case where a supply cable is connected to an electrical outlet in a state of separation of the cable from the outlet; a first non-volatile storage unit and a second volatile storage unit configured to store first and second values, respectively, the first and second values indicating whether being in a valid state for receiving the start-up instruction; a determination unit configured to determine whether the first value indicates the valid state and is different from the second value; and a control unit configured to restrict a second electric power supplied to the image processing unit, and to bring the image processing apparatus into the valid state.
