Abstract

PURPOSE:To constantly adjust a detecting sensitivity and to suitably set the detecting sensitivity in accordance with the request of an user by providing an adjusting means to adjust an alarm threshold value and an index means to show an adjusted value by the moving distance of a shutter fitting magnet for sensor setting distances to a shutter. CONSTITUTION:A means 7 to adjust the alarm threshold value to execute an alarm output from the lowering of a magnetic field detecting output by a hole sensor 4 and an index means VR to show the adjusted value of the alarm threshold value by this adjusting means 7 by a magnet moving distance to generate the alarm output for the setting distances of the sensor 4 to a shutter 1 are provided. The operation part of the adjusting means 7 is adjusted so as to indicate the same position of the magnet moving distance by the index means VR even when the sensor setting distances are different. Thus, the same detecting sensitivity can be obtained to shutter opening.
