<p>PROBLEM TO BE SOLVED: To provide a security apparatus having an optical sensor for detecting an opening state of an upper case, the apparatus being designed so as to avoid fraudulent break of the optical sensor, also avoid erroneous operation of the optical sensor due to external light, and facilitate the mounting of the optical sensor.SOLUTION: Near a lower side plate part 3b3 of a lower case 3, first and second shield plate parts 11, 12 and a guiding plate part 13 located between them are formed. First and second locking pawl parts 14, 15 for locking first and second projecting plate parts 10b, 10c of a sensor substrate 10 are formed. The sensor substrate 10 is locked by being inserted between one end part 13b of the guiding plate part 13 and the first and second locking pawl parts 14, 15. Thus, an optical sensor 9 is accommodated and arranged between the first and second shield plate parts 11, 12 and between respective locking projection parts 14b, 15b of the first and second locking pawl parts 14, 15.</p> |
