Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
98 words
A disk cartridge characterized by: a) a disk cartridge-body (1) for accommodating therein a disk-shaped record medium (D) to become freely rotatable, an information signal capable of being recorded on said disk-shaped record medium (D); b) an openable and closable member (2, 14) for opening an closing an opening portion which is formed on said disk cartridge-body (1) to exchange said disk-shaped record medium (D); and c) a write-protecting mechanism (44, 45) formed on said openable and closable member (2, 14) to determine whether or not said information signal can be recorded on said disk--shaped record medium (D).
Claim 2
Dependent Claim
98 words
A disk cartridge characterized by: a) a disk cartridge-body (1) for accommodating therein a disk-shaped record medium (D) to become freely rotatable, an information signal capable of being recorded on said disk-shaped record medium (D); b) an openable and closable member (2, 14) for opening an closing an opening portion which is formed on said disk cartridge-body (1) to exchange said disk-shaped record medium (D); and c) a write-protecting mechanism (44, 45) formed on said openable and closable member (2, 14) to determine whether or not said information signal can be recorded on said disk--shaped record medium (D).
Claim 3
Dependent Claim
30 words
A disk cartridge according to claim 1, characterized in that said write-protecting mechanism (44, 45) is arranged so as not to disengage from said openable and closable member (2, 14).
Claim 4
Dependent Claim
39 words
A disk cartridge according to claim 2, characterized in that said write-protecting mechanism is provided with disengage-preventing means by which said write-protecting mechanism (44, 45) can be prevented from being disengaged from said openable and closable member (2, 14).
Claim 5
Dependent Claim
90 words
A disk cartridge according to claim 2 or 3, characterized in that said write-protecting mechanism is provided with a detected element (44) which can be slidably moved between first and second positions to determine whether or not an information signal can be recorded in said disk-shaped record medium (D), said first position indicating the fact that said information signal can be recorded in said disk-shaped record medium (D) and said second position indicating the fact that said information signal is inhibited from being recorded in said disk-shaped record medium (D).
Claim 6
Dependent Claim
91 words
A disk cartridge according to any one of claims 1 to 4, characterized in that said openable and closable member (2, 14; 114, 214) is secured to said disk cartridge body (1) by means of hinges (15, 115, 215a, 215b) so as to become freely openable and closable and said disk cartridge-body (1) is provided with locking means (16, 17) for locking said openable and closable member (2, 14; 114, 214) at the position in which said opening portion is closed by said openable and closable member (2, 14; 114, 214).
