Abstract

PURPOSE:To prevent the copied substance of an original from being obtained without permission by receiving infrared-rays from the necessary part of the original which absorbs infrared-rays, etc., and controlling the prohibition and the permission of copying. CONSTITUTION:The coated part 3a of a member which reflects the infrared-rays, etc., of the original 3 placed on a contact glass 2 is irradiated with the infrared- rays from an infrared-rays transmitting unit 16, which is absorbed in the coated part 3a and is not made incident on a receiving unit 17. Thus, image forming actions are prohibited through a control part 18 and the copied substance of the original is prevented from being obtained without permission, so that a secret is firmly kept. The above-mentioned effect can be obtained by providing the coated part of the member which reflects the infrared-rays outside and, moreover, the same results as above can be obtained by using an ultrasonic wave or an electromagnetic wave instead of the infrared-rays.
