Method for manufacturing a reel

Abstract

ingle reel with magnetic tape wound thereon is housed in a case. A restraining member, for restricting rotation of the reel by moving toward or away from the reel, is urged in a restraining direction by an urging member. The pushing-up portions of a releasing member are inserted into the through holes bored in the reel gear of the reel 2 so that the lower ends can abut a driving gear. The releasing member moves the restraining member in a releasing direction by moving according to the chucking operation of drive-side rotation drive. A method for manufacturing the reel includes molding a metal reel plate on a bottom surface thereof by insert molding by use of a metal mold in which a hold member for holding an inner peripheral surface of the reel plate is disposed on an outer periphery of a gate.

1 . A method for manufacturing a reel, comprising: 
 molding a metal reel plate on a bottom surface thereof by insert molding by use of a metal mold in which a hold member for holding an inner peripheral surface of said reel plate is disposed on an outer periphery of a gate.    
     
     
         2 . A method for manufacturing a reel, comprising: 
 molding a metal reel plate on an inner peripheral side of a reel gear by insert molding by use of a metal mold provided with a means of preventing interference between a gear-portion metal mold for molding said reel gear and said reel plate.
