A display device includes a front case; a cathode ray tube mounted on the front case; a main circuit board mounted on the rear side of the cathode ray tube; a circuit board frame, mounted to one among the front case and the cathode ray tube, to support the circuit board; a nonflammable and fire-retardant shield case to contain a fire that may break out in the interior of the display device, while providing a shielding effect which minimizes the radiation of electromagnetic waves generated by the display device and protects the display device from external electromagnetic interference; and a rear case that is combined with the front case to encase the interior of the display device. A top surface of the shield case includes an anode cap shield which protrudes upwardly from the surface to a fixed height to form openings on either side of an anode cap shield. A nonflammable and fireproof plate member having sides which block the openings formed by the anode cap shield is installed under a top plate of the shield case. Thus, the front and rear cases are made of a non-fireproof material, yet UL fire safety requirements are met.

A tension controller of a tape recorder maintains a constant tension in a running tape in the tape recorder. One embodiment includes a friction element for generating frictional force on one side of a tape reel disk, a tension controller for controlling the tension of the tape in which the tension controller is resiliently contacted by means of a spring in an upper face of the friction element, a slant cam formed at the edge of the contacted surface, and a tension pole formed in the upper direction on one side of a tension arm. A lifter minimizes the frictional action on the tape by being connected to a moving lever formed on the lower side of the tension controller and raising the tension during controller high-speed searching. Automatic control of the infinitesimal tension of the tape and prevention of interference in the tape during high-speed searching may be attained. The deck can be compact and the number of parts for the fabrication can be reduced to a simple structure, thereby providing many advantages in the fabrication process.
