A tape magazine-loading device according to claim 1, further including means for releasing said tape magazine from the loaded condition, said means being associated with said holder in such a manner as to bring said holder to said predetermined position spaced apart from said loading portion against the biasing force of said first spring means, wherein when brought to saiD predetermined position by said releasing means, the tape magazine held in said holder is pushed out forwardly by forward sliding movement of said operating lever due to said second spring means and said holder is locked at said predetermined position.

Claim 4

A tape magazine-loading device comprising: a. a baseplate provided on one surface thereof with a loading portion for a tape magazine containing a magnetic tape therein; b. left and right rotary arms extending forwardly over said one surface of said baseplate and rotatably mounted on said baseplate in such a manner as to move toward and away from said one surface of said baseplate; c. spring means biasing said rotary arms toward said one surface of said baseplate; d. a holder for said tape magazine that is rotatably mounted between the forwardly extending free ends of said left and right rotary arms; e. means for supporting said holder in such a manner as to maintain said holder in substantially parallel opposing relationship to said loading portion of said baseplate; f. an operating lever for locking said holder at a predetermined position spaced apart from said loading portion; and, g. tape magazine-releasing means for bringing said holder to said predetermined position against the biasing force of said spring means, wherein said loading portion of said baseplate includes capstans, reel shafts, and positioning guide members all of which extend toward said holder, wherein said holder comprises left and right sideplates disposed in parallel opposing relationship to each other, a top plate formed with apertures through which said capstans, said reel shafts and said positioning guide members are inserted, and a bottom plate disposed in parallel composing relationship to said top plate, said left and right sideplates being provided with outwardly projecting pins or rollers, said holder being provided with leaf springs for biasing said tape magazine toward said top plate when said tape magazine is inserted in said holder, wherein said operating lever comprises a platelike portion extending transversely behind said holder and forwardly and backwardly slidable, left- and right-hand side lever portions extending forwardly from the left- and right-hand side portions of said platelike portion so as to be inserted in said holder, and left and right locking lever portions extending from the left- and right- hand side portions of said platelike portion in opposing relationship to the outer surface of the left and right sideplates of said holder, said left and right locking lever portions being provided with horizontal engaging surfaces adapted for engagement with the outer peripheries of the pins or rollers of said holder and vertical engaging surfaces extending toward said baseplate from the fore-ends of said horizontal engaging surfaces and adapted for engagement with the outer peripheries of the pins or rollers of said holder, said holder being adapted to be locked at said predetermined position while the pins or rollers of said holder are disposed in engagement with said horizontal engaging surfaces, at this point said operating lever being slid backwardly so that when the engagement between the pins or rollers of said holder and said horizontal engaging surfaces is eliminated, said holder is moved toward said loading portion by the bias force of said spring means while said pins or rollers are being engaged with said vertical engaging surfaces, and wherein said tape magazine-releasing means includes a return lever provided with said baseplate and an interlocking lever having a portion extending toward said holder, said holder being pressed through said interlocking lever by actuation of said return lever while the same is being loaded in said loading portion, whereby the pins or rollers of said holder are engaged with the horizontal engaging surfaces of said operating lever so that said holder is locked at said predetermined position and the tape magazine in said holder is pushed out forwardly by forward sliding movement of said operating lever.

Claim 5

A tape magazine-loading device comprising: a. a baseplate provided on one surface thereof with a loading portion for a tape magazine containing a magnetic tape therein; b. left and right rotary arms extending forwardly over said one surface of said baseplate and rotatably mounted on said baseplate in such a manner as to move toward and away from said one surface of said baseplate; c. spring means biasing said rotary arms toward said one surface of said baseplate; d. a holder for said tape magazine that is rotatably mounted between the forwardly extending free ends of said left and right rotary arms; e. means for supporting said holder in such a manner as to maintain said holder in substantially parallel opposing relationship to said loading portion of said baseplate; f. an operating lever for locking said holder at a predetermined position spaced apart from said loading portion; and, g. tape magazine-releasing means for bringing said holder to said predetermined position against the biasing force of said spring means, wherein said loading portion of said baseplate includes capstans, reel shafts, and positioning guide members all of which extend toward said holder, wherein said holder comprises left and right sideplates disposed in parallel opposing relationship to each other, a top plate formed with apertures through which said capstans, said reel shafts and said positioning guide members are inserted, and a bottom plate disposed in parallel composing relationship to said top plate, said left and right sideplates being provided with outwardly projecting pins or rollers, said holder being provided with leaf springs for biasing said tape magazine toward said top plate when said tape magazine is inserted in said holder, wherein said operating lever comprises a platelike portion extending transversely behind said holder and forwardly and backwardly slidable, left- and right-hand side lever portions extending forwardly from the left- and right-hand side portions of said platelike portion so as to be inserted in said holder, and left and right locking lever portions extending from the left- and right- hand side portions of said platelike portion in opposing relationship to the outer surface of the left and right sideplates of said holder, said left and right locking lever portions being provided with horizontal engaging surfaces adapted for engagement with the outer peripheries of the pins or rollers of said holder and vertical engaging surfaces extending toward said baseplate from the fore-ends of said horizontal engaging surfaces and adapted for engagement with the outer peripheries of the pins or rollers of said holder, said holder being adapted to be locked at said predetermined position while the pins or rollers of said holder are disposed in engagement with said horizontal engaging surfaces, at this point said operating lever being slid backwardly so that when the engagement between the pins or rollers of said holder and said horizontal engaging surfaces is eliminated, said holder is moved toward said loading portion by the bias force of said spring means while said pins or rollers are being engaged with said vertical engaging surfaces, and wherein said tape magazine-releasing means includes a return lever provided with said baseplate and an interlocking lever having a portion extending toward said holder, said holder being pressed through said interlocking lever by actuation of said return lever while the same is being loaded in said loading portion, whereby the pins or rollers of said holder are engaged with the horizontal engaging surfaces of said operating lever so that said holder is locked at said predetermined position and the tape magazine in said holder is pushed out forwardly by forward sliding movement of said operating lever.

Claim 6

A tape magazine-loading device according to claim 1, said operating lever slidably mounted to a subbaseplate integral with said baseplate so as to slide forwardly and backwardly and biased by operating lever spring means in the extending direction of the surface of said baseplate toward the free ends of said left and right rotary arms, whereby when brought to said predetermined position of said tape magazine-releasing means the tape magazine held in said holder is pushed out forwardly by forward sliding movement of said operating lever due to said operating spring means.
