<p>PURPOSE:To prevent bedewing at rotary and fixed drums and to reduce the friction of a magnetic head under a high-humidity environment by linking the vicinity of the magnetic head and a power supply part mechanically by a heat conducting member and effectively utilizing the heat generation of the power supply part. CONSTITUTION:A power supply part 6 and a fitting member 5 are linked by a heat conducting member 7, and heat generated at the power supply part 6 is transmitted through the members 7 and 5 to drums 3 and 4 or a magnetic head 2. Namely, on the side of the power supply part 6, the generated heat is radiated to the side of the member 5 and on the other hand, the side of the drums 3 and 4 and the head 2 is heated by the heat on the side of the power supply part 6. Thus, the increase of a temperature at the power supply part 6 can be reduced and unified, and bedewing at the drums 3 and 4 can be prevented by effectively utilizing the heat generated by the power supply part 6 without consumping any excess power. Further, when using the device under the high-humidity environment, the friction at the head 2 is reduced as well, and wearing resistance is improved.</p> |
