Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
138 words
An imagewise information processing apparatus comprising: input means for inputting imagewise information; writing-in means for writing in information signal from said input means into an erasable optical recording medium; reading-out means for reading out the information signal written in into the optical recording medium; image forming means for reproducing an image from the information signal from said reading-out means; erasing means for erasing the information signal written in into the optical recording medium, said erasing means being controlled independently of said writing-in means and said reading-out means; and control means for driving said erasing means during a period from the completion of a reproduction by said image forming means to the commencement of a next writing-in by said writing-in means to cause said erasing means to automatically erase the information signal written in into the optical recording medium.
Claim 2
Dependent Claim
138 words
An imagewise information processing apparatus comprising: input means for inputting imagewise information; writing-in means for writing in information signal from said input means into an erasable optical recording medium; reading-out means for reading out the information signal written in into the optical recording medium; image forming means for reproducing an image from the information signal from said reading-out means; erasing means for erasing the information signal written in into the optical recording medium, said erasing means being controlled independently of said writing-in means and said reading-out means; and control means for driving said erasing means during a period from the completion of a reproduction by said image forming means to the commencement of a next writing-in by said writing-in means to cause said erasing means to automatically erase the information signal written in into the optical recording medium.
Claim 3
Dependent Claim
35 words
An imagewise information processing apparatus according to claim 1, wherein said control means causes said erasing means to commence the erasing on the basis of a reproduction completion signal supplied from said image forming means.
Claim 4
Dependent Claim
47 words
An imagewise information processing apparatus according to claim 1, wherein said control means includes time counting means and said control means causes said erasing means to commence the erasing after the lapse of a predetermined time from the completion of the reproduction by said image forming means.
Claim 5
Dependent Claim
23 words
An imagewise information processing apparatus according to claim 3, wherein said control means includes means for adjusting said time to a desired time.
Claim 6
Dependent Claim
29 words
An imagewise information processing apparatus according to claim 1, wherein said control means includes a timepiece and causes said erasing means to commence the erasing at a predetermined time.
Claim 7
Dependent Claim
32 words
An imagewise information processing apparatus according to claim 1, wherein said control means includes means for causing said erasing means to commence the erasing on the basis of a command from outside.
Claim 8
Dependent Claim
18 words
An imagewise information processing apparatus according to claim 1, wherein the optical recording medium is a magneto-optical disk.
Claim 9
Dependent Claim
30 words
An imagewise information processing apparatus accorcing to claim 1, wherein said image forming means includes means for directly reproducing an image from the imagewise information input from said input means.
Claim 10
Dependent Claim
18 words
An imagewise information processing apparatus according to claim 1, wherein said input means is an original reading device.
Claim 11
Dependent Claim
26 words
An imagewise information processing apparatus according to claim 7, wherein said erasing means comprises a magnet for regularizing the direction of magnetization of said magneto-optical disk.
Claim 12
Dependent Claim
19 words
An imagewise information processing apparatus according to claim 1, wherein said image forming means is a laser beam printer.
