摘要： Given n move information signals and m slits 22 (n and m: positive integers), the number of photodiodes associated with the m slits 22 is set to n×ma (a: a positive integer). By doing so, all of the (n×ma) photodiodes 23 can necessarily be positioned evenly in units of an equal number against the slits 22 and the move information signals. Also, the photodiodes can be subdivided more than in a conventional optical encoder having photodiodes counting a number represented by m×n, which is a common multiple of the number m of the slits 22 and the number n of move information signals. Thus, with light reception area of each photodiode reduced, shifts, distortions, variations and the like of the move information signals can be suppressed, resolution can be enhanced, and accurate move information signals can be obtained.

摘要： The photoelectric encoder of the present invention has a light-emitting device and light-receiving devices arranged in one direction in a region that light from the light-emitting device can reach. When a moving object that alternately has a light-on portion that produces a state in which light is incident on the light-receiving device and a light-off portion that produces a state in which light is not incident on the light-receiving device passes at a prescribed movement frequency in the one direction, an output of each of the light-receiving devices takes a value corresponding to the incidence or nonincidence of light on the light-receiving device. A logical operating section carries out operation of the logical values expressed by the outputs of the light-receiving devices to form an output signal that has a frequency different from the movement frequency.

摘要： This optical encoder includes a light emitting section and a plurality of light receiving elements placed so as to be aligned in one direction in an area where a light beam from the light emitting section may reach. A moving object includes a light-ON section, a light-OFF section and an index pattern section. The light receiving element outputs a first light receiving signal when the light-ON section and the light-OFF section of the moving object pass through a predetermined position corresponding to the light receiving element. The light receiving element outputs a second light receiving signal when the index pattern section of the moving object passes through a predetermined position corresponding to the light receiving element. The output section outputs an incremental channel signal indicating movement information of the moving object based on the first light receiving signal while outputting an index channel signal indicating reference position of the moving object based on the second light receiving signal. The incremental channel signal and the index channel signal are out of phase with each other.
