Abstract

PURPOSE:To form a synthetic image by providing a display member where an image can be selectively formed on a part of the path of light, which is emitted from a light source, and shields the path in order to form a copy image, and a control means driving and controlling the display member and forming the image. CONSTITUTION:A copying machine is provided with the control part 40 connected to a control panel 30, a liquid crystal driving part 50 connected to the control part 40, and a translucent type liquid crystal display plate 60 connected to the liquid crystal driving part 50. After the control part 40 receives an image, which is desired to be added to an original image, from the control panel 30 and processes data, it sends image information to the liquid crystal driving part 50. On receiving the processed image information, the liquid crystal driving part 50 drives the liquid crystal plate 60, where the images such as a character can be displayed. Since the copying machine is provided with the control means 40 forming the image by driving and controlling the display plate 60 where the image can be selectively formed in the part of the path of the light, which is emitted from the light source, and shields the path in order to form a copy image, the synthetic image can be formed by adding other images to the original image.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying machine for copying an original, and more particularly to a copying machine capable of forming a copied image by adding another image to the image of the original. It's about machines.

[Prior Art] Conventionally, a copying machine simply copies an image of a document placed on a document table.

[Problems to be Solved by the Invention] However, when a large number of originals without page numbers are copied using a copying machine that simply copies the image of the original placed on the original platen, when the originals are rearranged later, they become scattered. There was a risk that the order would become unclear. Furthermore, there is a risk of forgetting to record the copy shelf life and not knowing when the copy was made, and there is a problem that another image cannot be automatically added to the copy image.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a copying machine that can form a copy by adding an image in addition to the original image.

[Means for Solving the Problems] In order to achieve this object, the copying machine of the present invention provides a copying machine that is provided in a part of the path of light emitted from a light source to form a copied image, and that blocks the path. The apparatus includes a display section (j) capable of selectively forming an image, and a control means for driving and controlling the display member to form the image.

[Operation] In the copying machine of the present invention having the above configuration, the operator instructs the control means to add another image to the final copied image, and causes the display member to display the other image. Thereafter, the original is placed on the original table and a copying operation is performed to obtain a copied image containing the image desired by the operator.

[Example] Regarding the copying machine of the present invention, Fig. 1 shows a schematic configuration of an embodiment of a photosensitive and pressure-sensitive copying machine capable of full-color copying, and Fig. 2 shows a cross section of a document table. Refer to and explain.

The copying machine 1 of this embodiment uses photosensitive paper consisting of photosensitive pressure sensitive paper (microcapsule paper) and color developer paper. A movable original platen glass 2 and a movable original platen cover 3 are provided on the top plate portion of the copying machine 1, and a transmissive liquid crystal display board 60 for displaying images such as characters is embedded in the original platen glass 2. A desired original 4 is set face down on the original platen glass 2.

A light source using a halogen lamp 5 or the like is installed in the upper part of the copying machine 1, and it irradiates light in a line through a slit hole provided on the top surface of the machine toward the document table glass 2, and emits light from the halogen lamp 5. The fallen light passes through the transparent document platen glass 2 and the transmissive liquid crystal display panel 60, and is reflected by the document 4 placed thereon. Therefore, exposure scanning of the original 4 is performed by moving the original platen glass 2. Manuscript 4
The light reflected from the screen passes through a filter 6 for adjusting the color tone of the copied image, enters the projection lens 7, and enters the projection lens 7.
The direction of the projected light is changed by a pair of reflection mirrors 8 and 9, and an image is formed on a microcapsule paper 11 located along an exposure table 10. 'The above reflecting mirrors 8, 9
is attached to a mirror mounting plate, and the optical path length and focus are adjusted by finely adjusting the mounting position of the mirror mounting plate.

On the other hand, a long microcapsule paper 11 is wound around a cartridge shaft 12 and housed in a removable cartridge, and one end of the paper is wrapped around a cartridge shaft 12.
4a, 14b, 14c, pressure developing device 13, and separation mechanism 1
4d and reaches the winding shaft 15. That is, the microcapsule paper 11 that has come out from the lower part of the cartridge is guided by the feed roller 14a1 and the guide roller 14b, passes below the exposure table 10, and then is supplied to the pressure developing device 13, and then The microcapsule paper 11 that has passed through the developing device 13 is transferred to a feeding roller 14C1 and a separation mechanism 14d.
and the meandering adjustment roller 1.4e, and then wound onto the winding shaft 15. Incidentally, the unexposed microcapsule paper 11 after leaving the cartridge is maintained in an unexposed state by the light shielding cover.

In addition, the transport speed of the microcapsule paper 11 is controlled to be constant and is made to match the moving speed of the document platen glass 2, so that the microcapsule paper 11 contains the document when passing through the exposure table 10. Latent images of predetermined lines are sequentially formed.

A paper feed cassette 17 containing developer paper (recording paper) 16 constituting a paper feed device is installed below the pressure developing device 13, and a suction cup-type paper feed mechanism that sucks paper using negative pressure suction is installed. 18 is provided, and the developing paper 16 is fed to the paper feeding mechanism 1.
8, the sheets are taken out one by one and conveyed by a feed roller 19a, a pinch roller 19b, and a developing paper roller 19c,
After the leading end is aligned by the resist gate 19d and the resist gate 19e, the resist is transported into the pressure developing device 13. In this way, the microcapsule paper 11 and the color developer paper 16 are supplied to the pressure developing device 13 in a state in which they are in close contact with each other and are integrated, and the microcapsule surface on which the latent image of the microcapsule paper 11 is formed and the developer paper 16 are separated. The roller 13 is sandwiched between the small-diameter roller 13a and the backup roller 13b as a unit with the colorant-applied surface in contact with the inner surface, and pressure is applied thereto. This pressure destroys the unexposed microcapsules and forms an image on the color developing paper 16.

After the microcapsule paper 11 and the color developer paper 16 that have come out of the pressure development device 13 are separated by a separation mechanism 14d, the color development of the color developer paper 16 is promoted by the heat roller 20a of the heat fixing device 20, and an image is formed. After that, the paper is delivered to a paper ejection tray 21 by a paper ejection roller. The separated microcapsule paper 11 is wound onto the winding shaft 15 via a meandering adjustment roller 14e.

Next, with reference to FIG. 4, the outline of the configuration of the transmissive liquid crystal display panel 60 and its control means mounted on the copying machine of this embodiment will be briefly described.
