Abstract

PURPOSE:To ensure the operation, by providing a switch in which the on/off operation shows a hysteresis characteristic so as to behave a specific operating state corresponding to the range of depth to be used for photographing specified in an optical system. CONSTITUTION:A read switch 17 shows a hysteresis characteristic in which the on/off operation relates to the distance between the surface of a bottom plate 2 of a device 1 and original plane. The distance between the surface of the bottom plate 2 of the device 1 of the reader and the original plane when the read switch 17 is changed from ON to OFF is taken as a specified objective depth of an optical system L of the reader, and the display for improper read state is made by turning off the reed switch 17 when the surface of the bottom plate 2 of the device 1 floates more than the permissible range.
