Description

[Detailed Description of the Invention] Technical Field The present invention relates to a control device for a copying machine, more specifically,
The present invention relates to a control device that detects and displays these environmental conditions or issues a warning in a copying machine that is affected by the environment such as temperature and humidity.

BACKGROUND OF THE INVENTION Copying machines use supplies that are sensitive to temperature and humidity, such as paper, developer, and photoreceptors. Therefore,
To obtain optimal copies, the copier must be operated under a certain range of environmental conditions. However, copies are often placed under environmental conditions outside the above-mentioned ranges, first thing in the morning in winter or during the boiling season in summer, resulting in unsatisfactory copies or jams. In other words, in conventional copying machines,
Despite the usage environment conditions set,
Since the external environment cannot be detected and no warning is issued based on the detection output, optimal copying cannot be obtained and sometimes paper jams occur.

Purpose This invention was developed in view of the above-mentioned circumstances, and specifically detects and displays the environmental conditions in which the copying machine is placed, and outputs a warning when the value is outside a specific range. This was done for the purpose of preventing copy mistakes and the like.

Configuration In order to achieve the above object, the present invention includes a detection means for detecting temperature and humidity, and a copying operation that is permitted when the temperature and humidity from the detection means are within a predetermined value range, and when the temperature and humidity from the detection means are within a predetermined value range. a copying operation control means for prohibiting the copying operation when the copying operation is prohibited, first display data for warning of the occurrence of a copy image with background stains, second display data for warning of the occurrence of jam, and warning that copying is prohibited. storage means pre-stored with third display data explaining how to cancel copying prohibition and fourth display data explaining how to cancel copying prohibition; canceling means for canceling prohibition of copying operation of said copying operation controlling means; and said copying operation controlling means. outputs the detected temperature and humidity from the detecting means when the copying operation is permitted by the detecting means;
When the copying operation is prohibited and the temperature detected by the detection means is lower than a predetermined value, the temperature and humidity detected by the detection means, the first display data stored in the storage means, and the first display data are stored. The third display data and the fourth display data are output, and when the copying operation is prohibited and the detected humidity from the detecting means is higher than a predetermined value, the detected temperature and humidity from the detecting means and the fourth display data are output. It is characterized by having a control means for outputting the second display data stored in the storage means, the third display data, and the fourth display data, and a display means for displaying information from the control means. This is what I did. Hereinafter, the present invention will be explained based on embodiments.

FIG. 1 is a block diagram of essential parts for explaining one embodiment of the control device according to the present invention. In the figure, 1 is a temperature sensor, 2 is a humidity sensor, and 3 and 4 are analogs output from each sensor. An analog switch that switches the signal, and 5 a humidity sensor or an A/D that converts the analog output from the humidity sensor into a digital value.
A converting section, 6 is a control section that controls the entire copying machine and specific control of the present invention, and 7 is a control section from the control section 6 that controls which of the temperature sensor output or the humidity sensor output is connected to the A/D conversion section. An input switching signal line input to the analog switch 3 or 4, 8 a release key to be described later, 9 an input pull-up resistor, and 10 a display for displaying display data output from the control unit 6 on a display unit such as a CRT. interface, 1
1 is a display section. Temperature sensor 1, humidity sensor 2
The signals output from the A/D converter 5 are switched by the input switching signal line 7 and the analog switches 3 and 4 and input to the A/D converter 5, and the output from the A/D converter 5 is read into the controller 6. The read temperature and humidity data is normally displayed on the display section 1 via the display interface 10, as shown in FIG.
1 is displayed. If the temperature/humidity data exceeds a specific range, for example 10° C. to 30° C. and 30% to 90%, a warning is displayed as shown in FIG. 3 or 4.

Figure 3 shows the case when the temperature is below 10°C, and displays the concern about background stains on copies that are thought to be caused by the photoreceptor temperature being too low (first display data; I'm worried about it getting dirty〓), and it also shows that copying is not possible (third display data; 〓Copy not possible〓 in Figures 3 and 4). However, if the user determines that there may be background stains, the copy prohibition can be canceled by pressing the release key or clear key 8. For example, a "release key" is displayed to cancel the prohibition, and an explanation of how to cancel the copy prohibition is displayed to the user (fourth display data).

Figure 4 shows the case when the humidity exceeds 90%, and shows the concern about jamming that is thought to occur due to too high humidity (second display data; there is concern about jamming in Figure 4). ing. That is, in both FIGS. 3 and 4, the unusable temperature and humidity range is displayed at the same time, and it is clear that the current environmental conditions are outside the usable temperature and humidity range.

Effects As is clear from the above explanation, according to the present invention, (1) the environmental conditions in which the copying machine is placed are displayed;
You can see at a glance whether the copier is being used under optimal conditions.

(2) When environmental conditions are outside a certain range, a warning is issued and the copying operation is prohibited, so it is possible to prevent mistakes such as copying.

(3) When the user determines that it is not necessary to make a quick copy or an optimal copy, the user can release the copy prohibition mode and copy.

There are advantages such as
