Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
126 words
A tape read out device, such as adapted to be automatically operated by inserting a cartridge containing a recorded magnetic tape, comprising a support frame having an insertion end for a cartridge, a support plate for said frame, said frame pivoted adjacent its cartridge inserting end to said support plate so that it can be rotated, by a simple downward manual pressure at its said end, between a lower position where the cartridge is completely inserted and an upper position for said cartridge insertion or removal, a first spring urging said frame towards the lower position; the device also comprising a pivotable means on said plate for hooking the frame at its said two positions and being simultaneously effective to provide for ejecting an inserted cartridge.
Claim 2
Dependent Claim
126 words
A tape read out device, such as adapted to be automatically operated by inserting a cartridge containing a recorded magnetic tape, comprising a support frame having an insertion end for a cartridge, a support plate for said frame, said frame pivoted adjacent its cartridge inserting end to said support plate so that it can be rotated, by a simple downward manual pressure at its said end, between a lower position where the cartridge is completely inserted and an upper position for said cartridge insertion or removal, a first spring urging said frame towards the lower position; the device also comprising a pivotable means on said plate for hooking the frame at its said two positions and being simultaneously effective to provide for ejecting an inserted cartridge.
Claim 3
Dependent Claim
119 words
A tape read out device as claimed in claim 1, wherein said hooking swinging meMber comprises an inverted U element, having a first arm sidewise pivoted to said support plate and a second arm entering the frame through a suitable aperture; the second arm of the hooking member being engaged by the inner end edge of an inserted cartridge for the device operation, said first arm being provided with stop seats for the frame at its two end positions engaging with a member projecting sidewise of said frame; said hooking member being subjected to the return action of a resilient means being effective to rotate it to its forward or engaging position for the frame to its upper position.
Claim 4
Dependent Claim
70 words
A tape read out device as claimed in claim 1, wherein said frame is provided with a projecting portion at its cartridge insertion end, which is manually acted upon by a slight downward pressure to rotate the frame to its upper or ejection position for an inserted cartridge; said frame being subjected to the spring return action of a resilient means being effective to hold it at its lower position.
