Abstract
In a cartridge type magnetic type recorder of the type wherein an operating frame and a cartridge receiving frame are pivotally interconnected, the receiving frame is moved to the reproducing position in a direction perpendicular to the direction of loading of the cartridge so as to couple the cartridge with a driving motor and reproducing or recording head, there are provided a pin for one side of the operating frame, a cartridge ejecting lever having a cam, and a sliding frame having a cam slot. The pin cooperates with the cam and cam slot for ejecting the cartridge.
Claims21
In a cartridge type magnetic tape recorder of the type comprising an operating frame, means for pivotally mounting one end of said operating frame to a stationary member of the tape recorder, a cartridge receiving frame for receiving a cartridge of the magnetic tape and pivotally connected to the other end of said operating frame, means for moving said receiving frame in a direction perpendicular to the direction of loading of said cartridge thereby moving said cartridge to a reproducing position, a head plate disposed at the reproducing position, a reproducing-recording head and pinch rollers mounted on said head plate, a reel drive shaft for driving the magnetic tape, and a cartridge ejecting lever extending in the direction of loading of said cartridge, the improvement which comprises a sliding frame provided with an inverted L-shaped cam slot and arranged to be slid on said operating frame by the cartridge loaded in said receiving frame, a cam mounted on said ejecting lever, and comprising upper and lower horizontal portions interconnected by an inclined portion, an operating member projecting from one side of said operating frame to engage said cam slot and said cam, and spring means for urging said cartridge ejecting lever and said sliding frame to their inoperative positions.
In a cartridge type magnetic tape recorder of the type comprising an operating frame, means for pivotally mounting one end of said operating frame to a stationary member of the tape recorder, a cartridge receiving frame for receiving a cartridge of the magnetic tape and pivotally connected to the other end of said operating frame, an engaging member projecting from one side of said operating frame such that said engaging member is engaged by the front end of said cartridge loaded in said receiving frame for moving the same to a reproducing position in a direction perpendicular to the direction of loading of said cartridge thereby coupling said cartridge with drive means and reproducing means, the improvement which comprises a projection provided for said receiving frame, said operating frame being provided with an opening for receiving said projection, and clamping means mounted on said receiving frame for maintaining the engagement between said projection and said opening.
In a cartridge type magnetic tape recorder of the type comprising an operating frame, means for pivotally mounting one end of said operating frame to a stationary member of the tape recorder, a cartridge receiving frame for receiving a cartridge of the magnetic tape and pivotally connected to the other end of said operating frame, an engaging member projecting from one side of said operating frame such that said engaging member is engaged by the front end of said cartridge loaded in said receiving frame for moving the same to a reproducing position in a direction perpendicular to the direction of loading of said cartridge thereby coupling said cartridge with drive means and reproducing means, the improvement which comprises a locking lever for establishing rapid feeding and play back states, a locking member for locking said locking lever in either one of said states, transfer means for switching the operation of said tape recorder to an automatic feeding operation, and means for operating said locking lever by said transfer means.
In a cartridge type magnetic tape recorder of the type comprising an operating frame, means for pivotally mounting one end of said operating frame to a stationary member of the tape recorder, a cartridge receiving frame for receiving a cartridge of the magnetic tape and pivotally connected to the other end of said operating frame, an engaging member projecting from one side of said operating frame such that said engaging member is engaged by the front end of said cartridge loaded in said receiving frame for moving the same to a reproducing position in a direction perpendicular to the direction of loading of said cartridge thereby coupling said cartridge with drive means and reproducing means, the improvement wherein the upper surface of said receiving frame is provided with an opening, and a resilient stopping member is secured to said receiving frame with one end of said resilient stopping member protruded into the passage of said cartridge through said opening.
In a cartridge type magnetic tape recorder of the type comprising an operating frame, means for pivotally mounting one end of said operating frame to a stationary member of said tape recorder, a cartridge receiving frame for receiving a cartridge of the magnetic tape and pivotally connected to the other end of said operating frame, an engaging member projecting from one end of said operating frame such that said engaging member is engaged by the front end of said cartridge loaded in said receiving frame for moving the same to a reproducing position in a direction perpendicular to the direction of loading of said cartridge thereby coupling said cartridge with driving means and reproducing means, the improvement which comprises means for detecting one end of the magnetic tape contained in said cartridge, planet gear means driven by a drive source, a locking member operated by said detecting means for locking said planet gear means, an ejecting lever for ejecting said cartridge from said receiving frame and means for operating said ejecting lever when said planet gear means is locked by said locking member.
