The first casing 111 encloses and fits the second casing 113. The first tissue outlet 1111a is provided on the upper surface 1111 of the first casing 111. A lens aperture 1133a is formed on a side surface 1133 of the second casing 113. Engaging columns 1131 are provided on two other side surfaces of the second casing 113 and extend downward therefrom, respectively, wherein the two engaging column-disposed side surfaces of the second casing 113 are opposite. The second tissue outlet 1135 is provided on the upper surface of the second casing 113. The second tissue outlet 1135 of the second casing 113 corresponds in position to the first tissue outlet 1111a of the first casing 111. The casing 11 is engaged with and fixed in position to the base 13 by steps of: inserting the engaging columns 1131 of the second casing 113 into engaging slots 131 of the base 13, respectively; inserting bumps (not shown) provided in the engaging slots 131 into engaging holes 1131a of the engaging columns 1131, respectively; and enclosing the second casing 113 with the first casing 111 to assemble the casing 11.
The first casing 111 is made of a translucent material, such as a translucent acrylic material. The second casing 113 is made of an opaque material, such as an opaque acrylic material. The first casing 111 and the second casing 113 are of deep color, such as black. As described above, the casing 11 comprises two casings, with one enclosing and fitting another; hence, the battery chamber 15, the supporter 17, and the camera unit 19 covertly installed within the inner space of the fake tissue box are unlikely to be discovered from the outside.
Referring to FIG. 4, the base 13 and the battery chamber 15 together form a one-piece unit. The base 13 and the battery chamber 15 are made of plastics, for example. In a specific embodiment, the base 13 comprises four side walls 133a ̃3d defining an enclosed space and a bottom wall 133e enclosed by four said side walls 133a ̃133d. The bottom wall 133e has a hollowed-out region 1333 (as shown in FIG. 5) corresponding in position to the battery chamber 15.
The battery chamber 15 is centrally positioned in the enclosed space inside the base 13. In a specific embodiment, the battery chamber 15 is a box structure with an open side facing the hollowed-out region 1333 of bottom wall 133e. 
Referring to FIG. 5, a battery (not shown) is placed in the battery chamber 15 from the bottom of the base 13. To replace batteries, it is necessary to separate a battery cover 21 from the bottom wall 133e, take old batteries out, place new batteries in the battery chamber 15, and cover the hollowed-out region 1333 with the battery cover 21. The battery cover 21 is configured to be engaged with and fixed in position to the bottom wall 133e. Furthermore, the battery cover 21 is engaged with and fixed in position to the bottom wall 133e by a conventional means.
