Detailed Description of the Invention [Industrial Application Field] The present invention relates to a color image recording device that produces 1q color images by exposing a photosensitive recording medium using a mask original created based on color image information. It is something.

[Prior Art] Conventionally, this type of color image recording apparatus includes an electrophotographic method, an inkjet method, a thermal transfer method, etc., and reproduces and records a color image on paper or the like based on color image information. Furthermore, in the method using light-sensitive and pressure-sensitive paper, a color image recording device using a mask original has a mask original creating section 41 and a color image recording section 42, as shown in FIG. The creation unit 41 is composed of a laser printer using an electrophotographic method. In this case, 2 is a polygon scanner, 3 is a photoreceptor, 4 is a ring imager, 5 is a paper feed cassette, 6 is a fixing device, 21 is an exposure light source, 22 is an intermediate sheet, 23 is an intermediate sheet discharge tray, and 24 is a light and pressure sensitive paper,
25 is a color lid paper tray, 26 is a heat fixing machine, 27 is a color developer paper cassette, 28 is a pressure developing machine, 31 is an intermediate sheet registration roll, and 32 is an intermediate paper positioning device.

[Problems to be Solved by the Invention] However, when recording a color image on paper using a color image recording device that uses a mask master, it is necessary to already own a monochrome recording device capable of forming a mask master. Even if you have a color image recording device such as the one shown in FIG. 3, you must purchase a new color image recording device. The mask original plate used in a color image recording apparatus using the mask original plate can be easily formed using an already owned monochrome recording apparatus, and of course, black and white images can also be obtained.

However, since color images are not required very often, there is a waste of purchasing two types of recording devices and a waste of installation space.

``Object of the Invention'' This invention was made to solve the above-mentioned problems, and its purpose is to obtain a color image record by using a monochrome mask original created from color image information. A color image recording device can be formed using a monochrome recording device that the user already owns, and in that case, it can be used as a normal monochrome recording device with a simple switching operation, and it can also be used when necessary. This can be done by making the color image 1q.

[Means for Solving the Problems] In order to achieve this object, according to the present invention, a color image is created in which a photosensitive recording medium is exposed to light using a mask original created based on color image information to obtain a color image. In the recording device, a receiving port receives a monochrome image recording sheet output from a monochrome printing device capable of creating a mask master, an ejection path for discharging the monochrome image recording sheet received through the receiving port to the outside, and the recording sheet. The color image recording apparatus includes a supply path for receiving the recording sheet and supplying the recording sheet to an image forming section in the color image recording apparatus, and a switching means for switching between the discharge path and the supply path.

[Function] If the user already owns a monochrome recording device, by using the color image recording device of the present invention, the monochrome recording device can be used as a color image recording device.

Normally, if you want black and white recording, you can use the switching means as a discharge path and use it as a monochrome printer. If you want to record a color image, create multiple mask masters in a monochrome recording device using color image information, for example, color information corresponding to each RGB color, and use the switching means as a supply path to sequentially apply the mask masters to the exposed portion of this device. A photosensitive recording medium is exposed to light using the photosensitive recording medium, and a color image can be obtained on the photosensitive recording medium through processes such as development and color development.

[Example] Hereinafter, an example embodying the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of a monochrome printer and a color image recording apparatus according to the present invention in a combined arrangement. 1 is a monochrome printer, and in FIG. 1, a laser printer is arranged as an example. The polygon scanner 2 draws an electrostatic latent image by irradiating a charged photoreceptor 3 with laser light. The photoconductor 3 on which the electrostatic latent image has been formed is developed in a developing machine 4, and is then developed on plain paper or OH, which is supplied from a paper feed cassette 5.
The toner image is transferred onto the P sheet and fixed by a fixing device 6.

Typically, the monochrome laser printer 1 records data transmitted from a host computer.

Reference numeral 20 denotes a color image recording apparatus according to the present invention, which records an image using a mask original created from color image information.

Switching between pass 11 for black and white and pass 15 for color is 1
This is done by moving the chute No. 3 up and down using the solenoid 12. The entrances 14 of the intermediate seats 1 to 14 have wide openings that can be adapted to various printers since the heights differ depending on the printer. A monochrome printer is normally used in monochrome mode, and the paper is ejected to the ejection tray 11.

Next, the effect of color mode will be explained. In the color mode, the paper passes through the chute 15 and the paper leading edge position is determined by the paper leading edge alignment roller 31. After that, the positioning device 32
