Abstract:
A film-tape eraser with normally retracted dispensing head, comprising:a dispensing mechanism including a case with a dispensing heard located at a lower front of said case, said case having internally mounted an erasing film-tape that passes a front end of said dispensing head, and said case being provided at a bottom with a forward extended elastic strip, and at a rear end with a rearward projected stopper; a lower case being a hollow member having a front and a top opening for said dispensing mechanism to pivotally locate therein, said lower case being provided at two sidewalls with two release buttons, each of which having a locking stud outwardly projected from an upper part thereof, and said lower case including a bottom that serves as a slide way, against which a front free end of said elastic strip of said dispensing mechanism is elastically pressed to normally upward push said dispensing mechanism into a lifted position in said lower case; and an upper case being pivotally connected to said lower case to shield an upper part of said lower case, said upper case being provided at two sidewalls near lower rear portions thereof with two locking holes for engaging with said locking studs on two sidewalls of said lower case, and at an upper rear end with a forward projected stopper, against which said rearward projected stopper on said case of said dispensing mechanism is abutted to restrict said dispensing mechanism in said lower case with said dispensing head located in said lower case; whereby when said case of said dispensing mechanism is downward pushed at a top thereof, said dispensing mechanism sinks to compress the front free end of said elastic strip to slide forward along said slide way of said lower case, bringing said dispensing head to expose from said lower case, and when said downward push at the top of said case of said dispensing mechanism is released, an elastic tension of said compressed elastic strip springs said dispensing mechanism upward until said rearward projected stopper abuts against said forward projected stopper on said upper case again, and brings said dispensing head into said lower case.
