摘要： Disclosed is a device for detecting an incident position of radiation beam, particularly, its center or center of gravity. The detecting device is provided with a scanning type radiation beam sensing device having a plurality of radiation sensing elements in a linear arrangement, and the sensing device is disposed in such a manner that its radiation receiving surface may be substantially coincided with an incident surface of the radiation beam to be detected. When reading an output from the sensing device, the time sequential output signals from the sensing device are split into predetermined sections, and the signal quantities among the sections are compared. In this way, the position of the center or the center of gravity of the radiation beam on the incident surface is detected with the position corresponding to a split point of the signals as the reference.

摘要： An improved photoelectric detecting apparatus is disclosed in which a subject surface containing a pattern which diffracts light in a predetermined direction is scanned with spotlight and the diffracted light coming from the pattern is detected by means of photoelectric element so as to read out information of the pattern. The apparatus comprises a first photoelectric element for detecting the light diffracted in the predetermined direction, a second photoelectric element adapted for detecting light diffracted in directions other than the predetermined direction and an operational circuit for operating the signal derived from the first photoelectric element and that derived from the second one. Thus, when there is any diffractive matter such as flaw, dust and the like on the subject surface, diffracted light from the diffractive matter is detected by both the first and second photoelectric elements whereas diffracted light from the pattern is detected only by the first photoelectric element. By operating the outputs of the two photoelectric elements only the necessary information of the pattern can be read out.

摘要： A signal for designating a portion of information regions of a recording medium is sent from an external apparatus to an information processing apparatus so as to cause the information processing apparatus to record information on the designated portion of the information regions or to reproduce information from the designated portion of the information regions. The information regions of the recording medium consist of a specific region and a remaining region. It is determined whether the designated portion of the information regions falls within the specific region or the remaining region. When the designated portion of the information regions is determined to fall within the specific region, the recording of information is interrupted or the reproduction of information is interrupted.
