Abstract
Abstract An apparatus for reproducing a charge latent image prerecorded on a charge holding layer of a recording medium as a series of frames aligned in a line. The apparatus contains a reproducing head means composed of an electrode without a photo-modulation layer, an enabling means enabling the reproducing head means to reproduce a charge latent image only when the reproducing head confronts a charge latent image. The enabling means displaces the series of frames of charge latent image intermittently to align one of the series of frames with the reproducing head means.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
82 words
An apparatus for reproducing a charge latent image prerecorded on a recorded medium, comprising: said recording medium composed of at least a photo-modulation layer and a charge holding layer laminated thereto and holding said charge latent image. reproducing head means composed of at least an electrode without a photo-modulation layer; and enabling means enabling said reproducing head means to reproduce said charge latent image only at an instance that said reproducing head means confronts said charge holding layer recording said latent image.
Claim 2
Independent Claim
82 words
An apparatus for reproducing a charge latent image prerecorded on a recorded medium, comprising: said recording medium composed of at least a photo-modulation layer and a charge holding layer laminated thereto and holding said charge latent image. reproducing head means composed of at least an electrode without a photo-modulation layer; and enabling means enabling said reproducing head means to reproduce said charge latent image only at an instance that said reproducing head means confronts said charge holding layer recording said latent image.
Claim 3
Dependent Claim
40 words
An apparatus for reproducing a charge latent image as claimed in claim 1 wherein said enabling means displaces said series of frames of charge latent image intermittently to align one of the series of frames with said reproducing head means.
Claim 4
Dependent Claim
59 words
An apparatus for reproducing a charge latent image as claimed in claim 1 wherein said reproducing head means comprises a line head scanned by a reading light, and said line head confronting a part of one of said series of frames and said enabling means transporting said recording medium substantially perpendicular to an extending direction of said line head.
