Total Claims: 7
Claim 1
Independent Claim
182 words
A rewritable recording/display apparatus comprising: - a rewritable recording medium (5A, 5B, 5C; 55; 101) in which a color development reaction occurs by a first thermal energy at a first predetermined temperature, and in which a color extinguishing reaction occurs by a second thermal energy at a second predetermined temperature, the rewritable recording medium (5A, 5B, 5C; 55; 101) being capable of repeatedly performing recording and erasing of images; - at least one heating means (11A, 11B, 11C; 12A, 12B, 12C; 50; 103) for heating the rewritable recording medium (5A, 5B, 5C; 55; 101) by heating using the first or the second thermal energy; - recording control means (8; 22; 61, 66; 91; 109) for outputting an image recording signal according to a desired display image to make the heating means (11A, 11B, 11C; 12A, 12B, 12C; 50; 103) produce heat of the first thermal energy; and - erasing control means (8; 61; 92; 110) for outputting an image erasing signal according to a desired image erasing range to make the heating means (50; 103) produce heat of the second thermal energy.
Claim 2
Dependent Claim
133 words
A rewritable recording/display apparatus comprising: - a rewritable recording medium (55; 101) capable of recording with thermal energy at a predetermined temperature, capable of erasing with thermal energy at a temperature lower than the color development temperature, and capable of repeatedly performing recording and erasing of images; - color developing heating means (22; 50; 61, 66; 91; 103; 103a; 109) for recording an image on the rewritable recording medium (55; 101) by heating the rewritable recording medium (55; 101) so as to cause the color developing reaction; - erasing heating means (50; 103; 103b) for erasing the image when the image has been recorded; and - selection means (94) for selecting an object on which an image is to be formed from a recording sheet (49); and the rewritable recording medium (55; 101).
Claim 3
Dependent Claim
27 words
The apparatus according to claim 2, wherein one heating means (50; 103) is provided serving both as the color developing heating means and the erasing heating means.
Claim 4
Dependent Claim
36 words
The apparatus according to claim 2, wherein the color developing heating means (22; 50; 61, 66; 91; 103; 109) includes reduction image control means (65) for recording a reduced image by outputting a reduced image data.
Claim 5
Independent Claim
120 words
A method of erasing a rewritable record, comprising the steps of: - heating a rewritable recording medium (55; 101) by heating means (50; 103) with a first thermal energy to form an image; and - making the heating means (50; 103) produce heat of a second thermal energy to heat the rewritable recording medium (55, 101) so as to erase the formed image, while setting the extent to which the rewritable recording medium (55, 103) is fed with respect erasing of one line during erasing of the image to a value equal to or smaller than that of the extent to which the rewritable recording medium (55; 101) is fed with respect to formation of one line during image formation.
Claim 6
Dependent Claim
49 words
The erasing method comprising applying, for erasing an image, a plurality of energization pulses to a heating means (50; 103) for applying the second thermal energy to make the heating means (50; 103) produce heat by the second thermal energy in accordance with these pulses to erase the image.
Claim 7
Dependent Claim
40 words
The erasing method comprising making, for erasing an image, all heating elements of a heating means (50; 103) or the heating elements within a range equal to or larger than the recording area produce heat of the second thermal energy.
