Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
129 words
A notched cartridge locking and ejecting mechanism consisting of a deck having a motor, capstan, and reproducing head, a cartridge supporting mechanism forming a receiving area for said cartridge. a pair of locking arms arranged on said cartridge supporting mechanism and provided with an elastic material, the end portions of said arms projecting into said receiving area, and an ejecting mechanism engaging at the ends of said locking arms and having a return action with said elastic material; wherein said arms are being equipped with supporters capable of fitting into notches in the sides of the cartridge, whereby when the cartridge is inserted said supporters fit into said notches to hold the cartridge and said ejecting mechanism is operated to retract said supporters from said notches of the cartridge.
Claim 2
Dependent Claim
129 words
A notched cartridge locking and ejecting mechanism consisting of a deck having a motor, capstan, and reproducing head, a cartridge supporting mechanism forming a receiving area for said cartridge. a pair of locking arms arranged on said cartridge supporting mechanism and provided with an elastic material, the end portions of said arms projecting into said receiving area, and an ejecting mechanism engaging at the ends of said locking arms and having a return action with said elastic material; wherein said arms are being equipped with supporters capable of fitting into notches in the sides of the cartridge, whereby when the cartridge is inserted said supporters fit into said notches to hold the cartridge and said ejecting mechanism is operated to retract said supporters from said notches of the cartridge.
Claim 3
Dependent Claim
100 words
