PURPOSE:To select the function of, on necessity, the test pattern by enabling freely attaching and detaching of a test-pattern package to the device body. CONSTITUTION:A tray 31 that constiutes the test pattern package 30 is inserted in an equipment containing pocket 14. When the package 30 is inserted to the depth of the pocket 14 by pushing the rod 163 of an ejecting mechanism 16 into a cylinder 162, the hook 151 of the containing mechanism 15 fits in the dent 35 provided in the tray 31 autonomically securing the package 30 in place. When detaching the package 30, a push to an ejecting button 161 makes a releasing claw 153 rotate as resisting the elasticity of a spring 152, causing the hook 151 which is coaxial with the releasing claw 153 to turn that lets the hook 151 escape from the dent 35 of the tray 31.
