Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an image forming apparatus that forms an image on a photosensitive recording medium.

EPrior Art 1 Conventionally, this type of image forming apparatus irradiates a document with light and forms an image of the reflected or transmitted light on a photosensitive recording medium through an optical system such as a reflecting mirror, filter, or lens. A device is known that is configured to form a latent image or a visible image on the photosensitive recording medium. Specifically, U.S. Patent No. 4399
In the device using the photosensitive pressure sensitive recording medium (consisting of a photosensitive pressure sensitive sheet and color developer paper) proposed in the specification of No. 209,
A latent image is formed by exposure on a photosensitive pressure-sensitive sheet as a photosensitive recording medium, a developer paper is placed on the surface on which the latent image is formed and pressure is applied, and the developer paper is then heated to form the desired developer image. I was getting . This pressure processing is generally called pressure fixing, and a pressure roller is used. *The heat treatment is generally called heat fixing, and a heat roller is used.

[Problem to be Solved by the Invention 1] However, when pressure fixing is performed in a state where the outside air is hot and humid, the binder carried on the photosensitive pressure-sensitive sheet and the binder carried on the color developing paper fuse together, The photosensitive pressure sensitive sheet and the developing paper are in an adhesive state.

If the adhesive in this state is forcibly removed, the components supported on the photosensitive pressure sensitive sheet will be peeled off from the sheet and adhered to the developing paper, making it impossible to obtain a good developed image.

Similarly, when heat fixing is performed in a hot and humid environment, there is a problem in that the developer paper sticks to the surface of the heat roller.

[Object of the invention] The present invention has been made to solve the above problems,
If the device cannot operate normally by detecting temperature or humidity, the device will stop operating or go into standby mode.
An object of the present invention is to provide an image forming apparatus that can reliably form an image only when normal operation is possible.

[Means for Solving the Problem] In order to achieve this object, the image forming apparatus of the present invention includes a temperature detection means for detecting the temperature inside the apparatus or a humidity detection means for detecting the humidity, and a temperature detection means for detecting the humidity inside the apparatus. A control means for stopping the device or putting it on standby is provided.

[Function] In the present invention having the above configuration, when either or both of the temperature detected by the temperature detection means and the humidity detected by the humidity detection means are outside the guaranteed operation range of the device, the control means controls the device. Stop or standby.

[Example 1] Hereinafter, an example embodying the present invention will be described with reference to the drawings. In the following examples, an embodiment will be shown in which a photosensitive and pressure-sensitive paper for one color, which is proposed in U.S. Pat. No. 4,399,209, is used as the photosensitive paper. Although it is necessary to make some changes to the fixing system, the exposure system can be used as is.

First l! The structure of the image recording apparatus will be explained with reference to FIG. S1.1 Inside the image recording apparatus 100, a light source 12 is disposed at the bottom, and a color correction filter 13 is disposed on the right side thereof.

Further, on the right side of the color correction filter 13 is a diffused reflection plate 1.
4 is arranged, and a document table glass 15 is arranged above it. A tray 6 is arranged above the document table lath 15, and a photosensitive and pressure sensitive paper roll cassette 1 is fixed on the tray 6. A photosensitive and pressure sensitive paper 2 is stored inside the photosensitive and pressure sensitive paper roll cassette 1 on the right side. A spring 4 is arranged below the tray 6, and an exposure table 3 is arranged below the spring 4.
is drivably fixed to the tray 6 via the spring 4. On the left side of the tray 6 is a pressure fixing roller 8.
has been placed.

A paper feed roller 11 and color developing paper 10 are housed inside. A document protection sheet 16 is drivably housed between the exposure table 3 and the document table glass 15. A temperature/humidity sensor 20 is disposed below the photosensitive and pressure sensitive paper roll cassette 1 and near the paper passage path of the photosensitive and pressure sensitive paper 2.

A heater 23 is arranged below the diffused reflection plate 14,
A controller 22 is arranged below the heater 23. The heater 23 is connected to the controller 2
It is connected to an AC power supply 21 via 2. 2 shows an operation panel of the image recording apparatus shown in FIG. 1, and a monitor LED 24 is connected to the controller 22. As shown in FIG.

Next, the operation of the image recording apparatus will be explained. *First, place a document (not shown) on the document protection sheet 16. Thereafter, the original protection sheet 16 is inserted into the image recording apparatus 100, and the exposure table 3 is lowered to bring the photosensitive pressure sensitive paper 2 and the original protection sheet 16 into close contact with each other by the force of the spring. And light source 1
2 is turned on, only the light that has passed through the color correction filter 13 is diffusely reflected by the diffuse reflection plate 14, and the original protection sheet 16 is
exposing the original (not shown) fixed to the
After the 0 gs light forming a latent image on the photosensitive and pressure sensitive paper 2 ends, the exposure table driving device (not shown) is driven to raise the exposure table 3 and bring the photosensitive and pressure sensitive paper 2 into close contact with the document protection sheet 16. Then, the developer paper 10 is taken out from the developer paper cassette 9, overlapped with the photosensitive and pressure sensitive paper 2, and passed through the pressure fixing roller 8, so that the latent image formed on the photosensitive and pressure sensitive paper 2 is transferred onto the developer paper 10. Dedicated to. Thereafter, only the color developing paper 10 is passed through a heat fixing roller 7 to improve color development, and an image is output.

Next, the present invention will be explained in detail with reference to FIG. The controller 22 detects whether the temperature and humidity inside the image recording apparatus detected by the temperature and humidity sensor 20 installed inside the image recording apparatus are within the guaranteed operation range or within the range compared with preset parameters. The monitor LE
Turn on D24, but if it is out of range, the above 24
The monitor LED is turned off and the heater 23 is activated. At this time, this device does not perform any recording operation.
However, when the temperature and humidity inside the image recording apparatus fall within the operable range again, the controller 22 turns on the monitor LED 24 and returns to normal operation.

The present invention is not limited to the embodiments detailed above, and various changes can be made without departing from the spirit thereof.

[Effect of the Invention 1] As is clear from the detailed description above, according to the present invention, a good image can be obtained by detecting the temperature and humidity inside the image forming apparatus and controlling the operation of the apparatus. And the photosensitive recording medium records images! ! An excellent effect of preventing jams such as sticking inside the surface can be expected.
