ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a cassette tape for a Video Tape Recorder (VTR) wherein an accommodation section for accommodating a small article is provided on the smaller-diameter reel side within a cassette body consisting of an upper and a lower part.
BACKGROUND OF THE INVENTION
VTR cassette tapes are used for such applications as sales promotion and product demonstration, and some tapes used for such applications are much shorter than general commercially-available recording and reproduction tapes such as 30- and 60-minute tapes. Thus, the inventor invented and applied for a cassette tape wherein the diameter of a reel is reduced for shorter tapes to form an extra space inside the cassette body, in which a section for accommodating a small article is provided (Japanese Patent Application No. 9-194973).
This conventional invention of a cassette tape has a structure wherein a recess section is provided in the top surface of the cassette body to accommodated a small article in the recess section, and wherein the recess section is closed by a cover. The inventor also improved this structure in which a small article is accommodated in the cassette body, in order to develop and apply for an invention wherein an opening in the accommodation section can be opened and closed (Japanese Patent Application No. 10-82987).
According to the latter invention, however, the cover is journaled into the body via a single vertical shaft so as to be laterally opened and closed, and is pushed back to a closed position by a spring. Thus, something may be caught in the tape to prevent the cover from being completely closed, and in this case, the cassette tape cannot be inserted in a video tape recorder. In addition, this invention requires the spring that pushes the cover and an engagement means having a complicated structure for closing the cover, thereby increasing the number of required parts and assembly steps. These are the problems with this invention.
DISCLOSURE OF THE INVENTION
The present invention has been provided in view of these points, and its object is to provide an efficient configuration to facilitate manufacture and to solve the operational problems to improve practicality and usability. Another object of the present invention is to provide a VTR tape that is effective in further activating business activities such as sales promotion.
These and other objects have been attained by a VTR cassette tape wherein the accommodation section for accommodating a small article therein is shaped like a recess and set at an end on a rear surface relative to a front surface from which a tape between the reels can be exposed, wherein a cover enclosing the accommodation section allows the external shape of the cassette body comprising the upper and lower parts to remain almost the same as the original shape, the cover being journaled into the upper part of the cassette body so as to open the accommodation section when rotated upward, and w herein a hook section detachably hooks the cover to the lower part of the cassette body so as to rotate and close the cover and to maintain that state.
