摘要： PURPOSE: To provide an inexpensive picture image recording device which has a high resolution by using a liquid crystal display panel having the number of pixels corresponding to one field in the vertical direction. CONSTITUTION: The device is provided with a light transmission type liquid crystal display panel 1 which displays picture image information, light sensitive material 5 which is disposed in opposition to one surface side of the panel 1, an image forming means 4 which forms the picture image on the panel 1 on the light sensitive material 5, a light source 10 disposed in opposition to the other surface side of the panel 1, and a synchronizing means 13 which synchronizes the lighting timing of the light source 10 to the picture image signal supplied to the panel 1. The synchronizing means 13 consists of a synchronizing separation circuit 11 which separates the vertical synchronization signals from the inputted picture image signals to output the separated signals, a recording start timing circuit 12 which outputs lighting timing signals in synchronization with the vertical synchronization signals outputted from the circuit 11 in the vertical blanking periods corresponding to two consecutive fields in one frame, and a light source driving circuit 14 which lights the light source 10 when the lighting timing signal outputted from the recording start timing circuit 12 is inputted.

摘要： PURPOSE:To copy an original picture beautifully irrelevantly to whether the original picture is transmissive or nontransmissive by irradiating the top surface of the original picture with light when the original picture is nontransmissive and irradiating the reverse surface of the original picture with the light when the original picture is transmissive. CONSTITUTION:When the original picture 18 is nontransmissive, a fluorescent tube 68 is turned on and the then the top surface of the original picture 18 is irradiated partially through a transparent plate 24 below a rod lens array 52. The reflected light from the original picture 18 is made incident on the rod lens array 52, part to part, as a carrier 48 moves, so that a latent image is formed on a photosensitive film 40c. When the original picture 18 is transmissive, on the other hand, a fluorescent tube 98 is turned on and then the reverse surface of the original picture 18 is irradiated through a light guide plate 100 and a transparent plate 92. Then the transmitted light from the original picture 18 is made incident on the rod lens array 52, part to part, as the carrier 48 moves to form a latent image on the photosensitive film 40c. Consequently, the original picture is copied beautifully irrelevantly to whether the original picture is transmissive or nontransmissive.

摘要： PURPOSE:To make the correcting range of an exposure wide, and to always copy a high quality image with a proper exposure by simultaneously, changing the brightness of an illuminating means and the scanning speed of an optical means. CONSTITUTION:Volume resistors 47 and 48 as adjusting means 40 adjusting the voltage values of respective driving voltages Vf and Vm, are connected between a stabilizing circuit 43 and an illuminating/driving circuit 46, and between a stabilizing circuit 44 and motor driving circuit 45, respectively. The volume resistors 47 and 48 are linked to change resistance values. When the resistance values of the volume resistors 47 and 48 are set high, the Vf increases, the Vm decreases, and the brightness of the illuminating means 24 is made high. Simultaneously, the rotational speed of a motor 23 is reduced, the scanning speed is reduced, and an exposing time is made long, so that the exposure is drastically increased. When the exposure is decreased, oppositely, the resistance values of the volume resistors 47 and 48 are set low.
