Abstract: A packaging bag contains a lens-fitted photo film unit in a pillow-type package. Optically transparent window sections are provided on front top and bottom portions of the packaging bag. And a belt-like shaped lightproof section is provided in a center portion of the window section. The window section is made translucent by printing a half-tone dot meshing with a white coating, so that the lens-fitted photo film unit is observable through the window section. The lightproof section is printed with a lightproof coating and covers the front of the taking lens. Opaque coating is printed on an opaque section, which is a portion except the window section and the lightproof section.

Abstract: A wrapping sheet made of a transparent sheet material such as polypropylene is provided with an opaque area where directions and the like are partially printed. A back side of the wrapping sheet is coated with an adhesive agent, which forms an adhesive agent layer. A dot printing (so-called an adhesion reduction) is applied to an area of the wrapping sheet covering an uneven part of a camera body at a printing rate of 20-100% to reduce an adhesion of the adhesive agent. The adhesion at edges of the wrapping sheet is higher than that of the area covering the uneven part in order to prevent the wrapping sheet from coming off.

Abstract: A package cover for packaging a lens-fitted photo film unit includes two side sheets covering two side faces of the lens-fitted photo film unit and an outer sheet covering front, rear, top and bottom faces thereof. The outer sheet is provided with edge portions formed of a plastic sheet which has heat-shrinkable property. After the side sheets are adhered to the lens-fitted photo film unit, the outer sheet is wrapped around it. The edge portions are shrunken by blowing a hot air thereon and fixedly stuck to edges of the side sheets.

Abstract: A lens-fitted film unit has a light tight unit body made up of a main body assembly including at least an exposure mechanism and injection molded polystyrene front and rear covers between which the main body assembly is interposed and a looped body-band label fitted to the light tight unit body. The looped body-band label is made of a polypropylene film sheet only, or otherwise a polypropylene film sheet laminated with a polystyrene film sheet, which has a thickness less than approximately 60 .mu.m. The polypropylene film sheet has a tensile strength greater than approximately 7.times.10.sup.3 N/m and a bending moment less than approximately 3.times.10.sup.-4 N.multidot.m and has a weight less than 1.5% with respect to the total weight of the injection molded polystyrene front and rear covers.

Abstract: A rotary magnetic head apparatus for use in a VTR and producing a low level of vibration by restraining the unbalance of an overall rotary body of the magnetic head apparatus. The apparatus includes a fixed cylinder for supporting a rotary shaft via bearings, a rotary cylinder secured to one end of the rotary shaft and having magnetic heads, and a motor rotor directly coupled with the other end of the rotary shaft. At least one first balancer and at least one second balancer are respectively provided in the rotary cylinder and the rotor so as to compensate for the unbalance of the rotary body composed of the rotary cylinder, the rotary shaft, and the rotor.
