The apparatus further includes an optical guide device for directing the image radiation from the irradiating device to the projecting device and the exposing device.
摘要:
An image transfer system wherein latent images formed on a photosensitive medium by exposure to a radiation according to image signals are developed into visible images, the photosensitive medium having a basic minimum amount of exposure to the radiation, which substantially defines a lower limit of a density-variable range in which a density of the visible images is varied according to an amount of exposure of the medium to the radiation. The present image transfer system includes a first device, a second device and a developing device. The first device is adapted to expose the medium a predetermined basic amount not larger than the basic minimum amount. The second device exposes local areas of the medium to a controlled intensity of the radiation represented by the image signals, and thereby cooperates with the first device to form the latent images on the photosensitive medium. The latent images are developed into the visible images by the developing device. Also disclosed a filter device for compensating for a difference in sensitivity of the medium to different wavelengths of the radiation for color imaging.

In an image recording apparatus utilizing a photo and pressure sensitive recording medium, an exposure unit emits a light to shine upon an original, and directs the light reflected from the original, toward the recording medium to expose the same thereby forming a latent image. A pressure developing unit is provided for pressurizing the exposed recording medium to develop the latent image thereon. A transport arrangement transports the recording medium from the exposure unit to the pressure developing unit. A regular reflection unit is provided for regular-reflecting the light from the exposure unit to expose the recording medium to the regular reflection light, thereby curing the recording medium.

Disclosed is a method of recording a picture onto a photosensitive and pressure-sensitive paper, which comprises the steps of: forming in advance a mask original form of a film having a light-transmitting portion and a non-light-transmitting portion corresponding to information of the picture; exposing the photosensitive and pressure-sensitive paper through the mask original form to thereby form a latent image on the photosensitive and pressure-sensitive paper; and pressure-fixing the photosensitive and pressure-sensitive paper carrying the latent image formed thereon. Further disclosed is an apparatus for carrying out the above method, which comprises: a mask forming means for forming a mask original form of a film having a light-transmitting portion and a non-light-transmitting portion corresponding to picture information of an original picture; an exposure means for exposing the photosensitive and pressure-sensitive paper through the mask original form formed by the mask forming means; and a pressure-fixing means for pressing the photosensitive and pressure-sensitive paper having a latent image formed by the exposure means to thereby perform pressure-development.
摘要:
An image recording system including a photosensitive medium having a layer of microcapsules formed on a substrate, each of the microcapsules having a photosensitive resin which is curable upon exposure to a radiation, and a colorless chromogenic material or color former which is capable of chemically reacting with a developer material, to form a visible image. The system further includes an exposing device for forming a latent image on the photosensitive medium according to image signals, by exposure of the medium to the radiation. The latent image is developed into a visible image. A communication device is provided for translating facsimile signals into corresponding picture signals. The facsimile signals are received from a remote facsimile transmitter through a communication channel and represent an image of a subject copy. Control means are connected to the communication device and the exposing device, for applying to the exposing device the picture signals received from the communication device as the image signals, to thereby form on the photosensitive medium the latent image represented by the picture signals.

摘要:
An overhead projector in which a light from a light source is transmitted through an original, and a resulting original image is projected on a screen by means of a projection optical system including a projection lens and a half-mirror. At the same time, the original image is transmitted through the half-mirror, and delivered to a record medium by means of an exposure optical system. The exposure optical system includes a shutter member which can be shifted between a shielding mode and a copying mode. In the shielding mode, the optical path of the exposure optical system is closed to permit projection on the screen. In the copying mode, the optical path is opened so that the original image, to which the record medium is exposed, is visualized on the record medium by a developing process. At the end of the copying mode, the record medium is discharged into a tray.

In a printing device according to the present invention, a housing assembly comprises a pair of housings which are rockably supported, with their respective open end portions abutting against each other. A platen is disposed in an abutment region where the open end portions abut. A keyboard is provided on the one housing, while a printing element is disposed inside the other housing. When the printing device is in a nonusable position, the two housings extend along one plane, thus defining a flat, rectangular outline of the housing assembly. When the device is in a usable position, the housings are rocked relatively, thus defining a substantially L-shaped outline of the housing assembly. As the housings rock in this manner, the printing element is brought to a printing position, where the element faces the platen.
摘要:
An imaging device wherein a latent image is formed on a photo and pressure sensitive recording sheet by exposing a light thereon and the latent image is then developed by applying a pressure thereon. The degree of pressing is automatically and/or manually controlled so as to obtain a visible image of stable color deepness and of good quality.

An image reader for reading images on a surface of a medium, having a feeding device for feeding the medium, carriage movable in a direction perpendicular to the direction of feed of the medium, a driving device for moving the carriage, and a reading head mounted on the carriage for reading the images on the medium surface. The image reader comprises an area setter for setting a reading area on the medium surface within which the images are read by the reading head. The reading area is set while the reading head is moved relative to the medium by the feeding and driving devices. The image reader further comprises a controller for controlling the feeding and driving devices and the reading head, to cause the reading head to read the images within the set reading area while the reading area is scanned by the reading head.
