Abstract

PURPOSE:To record images on the same photosensitive paper through the first and the second optical paths, by providing the first optical path for recording the image on a recording medium onto the photosensitive paper and the second optical path for converting a video signal to an image to record it onto the photosensitive paper. CONSTITUTION:The first optical path consisting of a lamp 1, a color correcting filter 3, a condenser lens 4, a focusing lens 6, and a half mirror 7 is used to record the image on a silver salt film 5 onto a photographic paper 8. The second optical path consisting of a cathode-ray tube 9, a video amplifier 10, a synchronous deflecting circuit 11, a color filter disc 12, and an optical system 15 is used to record the image recorded on a rotary disc 20 onto the photographic paper 8 through the half mirror 7. The image overlap printing is possible because these optical paths are constituted so as to overlap partially; and since a shutter 16 is provided on the second optical path, the selective image printing of both optical paths is possible.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing device for printing an image converted into a video signal onto a sheet such as paper.

Conventionally, image information temporarily recorded on a recording medium such as a silver halide film is printed onto photographic paper by a printing machine installed at a retail shop or the like where the image is requested.

However, when converting an image into a video signal into a tocoby, attention is focused on whether it is possible to print on plain paper using thermal printers, bubble jet printers, ink jet printers, or other photocopiers. Therefore, it requires expensive and large-sized equipment, and has many drawbacks in terms of image quality, resolution, granularity, etc. Also, a great deal of effort must be spent on maintaining the equipment.

It is an object of the present invention to provide an industrially useful printing device with excellent image quality that can solve the problems of the prior art.

Another object of the present invention is to provide a printing apparatus for video images which also enables printing on silver halide film.

In addition, the purpose of the first aspect of the present invention is to simply make slight changes to the burner machines that are conventionally installed in laboratory shops, or (・) to simply install Aguguter Gin without making any changes at all. It is an object of the present invention to provide a printing device capable of printing out a video signal recorded on a magnetic film or a magnetic disk, etc., with an additional cost.

Another object of the present invention is to provide a printing device for printing a color commercial code converted into a video signal with good cm 'E1.
It is intended to serve as a drain.

Also, another purpose of this investigation is the ll! of 1i112 ground film!
It is an object of the present invention to provide a printing device capable of multiplexing arbitrary images to I+11 at an arbitrary ratio.

In order to achieve such an object, the present invention has a first optical path for recording an image on photosensitive paper by projecting or reflecting an image on a recording medium such as a silver halide film, and a Braun tube or liquid crystal display. , a second optical path for recording the image on the image display means, such as a playback, on photosensitive paper, and this first optical path.
．． It extends through the second optical path and converges 1'ff at the photosensitive paper position so that it becomes f+.

This makes it possible to print images on a recording medium such as a silver halide film, overlapping them as desired.

Moreover, since the image display system can quickly create any image at any position and at any gradation using the Kagome Hakugo, it is possible to easily multiplex characters and 11IIlft.

Also, by making one of the optical paths not act on the photosensitive paper, IIfligI! can be selectively transmitted through the optical path of m1. You can print only .

In addition, li! is converted into a video signal. As a printer for Il images, at least Gb of the device can be used for printing conventional silver halide films.

Furthermore, in the present invention, each color signal is inverted and sequentially converted to black and white 1II.
u The image is supplied to the IV display panel and sequentially formed on the sensitive paper through the corresponding color filter, which has the effect of preventing a decrease in the resolution seen in color cathode ray tubes, etc. has.

The present invention will be described in detail below based on the drawings.

When the shutter 16 is not cutting off the light beam, the image on the display device 9 is formed on the photographic paper 8 via the second optical path consisting of the filter disk 1-2, the optical system 15, and the half mirror 7. In this way, in the present invention, # is configured so that the first optical path and the second optical path have a common imaging plane and a portion of each optical path overlaps, so that overprinting of +iui images is avoided. It's easy to make and the blood is the first thing. By cutting off the light from m1 in the second optical path, a 1III image can be selectively printed.

In addition, as shown in Section 2.1 (a) and (b), by making the first optical system and the second optical system detachable from each other, existing printing machines can be used as they are, or By just making some changes, you can easily create a hard copy of UTU 11 converted into a video signal.
