    • PURPOSE:To stop a working machine at a predetermined position of an oven to be operated with a predetermined stopping accuracy, by detecting an oven number and oven core information stored in an information memory provided in each oven by means of a reader mounted on a coke oven working machine, and outputting the oven number and oven information. CONSTITUTION:A coke oven working machine 6 having a reader 5 mounted thereon is provided on rails 7 laid on in a direction parallel to a group of coke ovens 1 comprising several hundreds of ovens 2 provided with an information memory 3 storing the oven number and oven core information. The oven number and the oven core information stored in a storage 8 of the memory 3 are output as a medium 4 from a data transmitting section 9. A sensor 11 of the reader 5 receives the data. An operation is conducted in a controller 12 to output an oven signal 14, and an error of a distance between the machine 6 and the oven core in the direction of travel is measured. When the error is within a predetermined position accuracy, an oven core signal 15 is output to stop the machine 6.

    • PROBLEM TO BE SOLVED: To provide a target alignment sensor whose constituent parts (e.g. a camera) are made proof against heat, dust and gases and which suffers little from the interference of an optical path and deterioration due to dew condensation. SOLUTION: This sensor consists of a target 6 having slits 7 representing the information of an oven number and attached to each coke oven 1, a light source arranged at the back of the target 6, fitted to a shifter and emitting light against the target 6, an image pickup means 9 arranged across the target 6 on the opposite side of the light source 8 and attached to a shifter and detecting the light emitted from the light source and passing the slits of the target, a controller 11 for judging the number of the oven according to the detected images of different brightness, a hood 13 for surrounding at least the image pickup means 9, an air purge device 14 formed near the optical path of the hood, a heat-generating transparent plate fitted front in of the pickup means, and an air agitator 17 disposed within the hood.
