Abstract tape recorder, particularly for purposes of recording data, comprising a tape cartridge which is adapted to fit, in the manner of a drawer, into a compartment in a recorder housing. The recorder housing contains the required elements for magnetically recording the data. The tape cartridge is latched into operating position within the compartment by a latching mechanism which includes the provision of spring loading for the brake and drive shafts of the recorder so that they may be readily retracted upon insertion and removal of the tape cartridge. The shafts are placed into driving relationship with the tape reels upon full insertion of the cartridge into its compartment. Also provided is a spring mechanism contained within the cartridge casing which is operative to perform a number of functions. The spring mechanism is effective to operate a brake against the tape reels when the cartridge is out of its compartment, and to release the brake when the cartridge is inserted. The spring mechanism is also effective to bias a pressure roller such that it holds the recording tape against the capstan in the recorder housing. The spring mechanism also acts when the latching mechanism is released to force the pressure roller against the capstan, thereby to kick out the cartridge a short distance from its compartment.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
86 words
A latching mechanism for latching a tape cartridge within a compartment in a tape recorder housing, comprising a pair of latch pins adapted to be received in recesses in said tape cartridge; a pair of spring-loaded shafts adapted to engage a pair of reels contained within said tape cartridge; means operatively connecting said latch pins and said shafts such that said latch pins are responsive to insertion within said compartment of the tape cartridge to produce retraction of said shafts until said cartridge is fully inserted.
Claim 2
Dependent Claim
86 words
A latching mechanism for latching a tape cartridge within a compartment in a tape recorder housing, comprising a pair of latch pins adapted to be received in recesses in said tape cartridge; a pair of spring-loaded shafts adapted to engage a pair of reels contained within said tape cartridge; means operatively connecting said latch pins and said shafts such that said latch pins are responsive to insertion within said compartment of the tape cartridge to produce retraction of said shafts until said cartridge is fully inserted.
Claim 3
Dependent Claim
34 words
A latching mechanism as defined in claim 1, in which said means comprises a movable latch plate to which said latch pins are integrally affixed, said latch plate operative to retract said spring-loaded shafts.
Claim 4
Dependent Claim
32 words
A latching mechanism as defined in claim 2, further comprising a release handle fixedly secured to said movable latch plate for actuation of said latch plate thereby to retract said spring-loaded shafts.
Claim 5
Dependent Claim
39 words
A latching mechanism as defined in claim 3, further comprising a pair of studs fixedly secured to said latch plate and spring means for respectively biasing said studs so as to urge the movable latch plate into latching position.
