Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to display control of an operation panel of a copying machine, and more particularly, to a copy process before a predetermined prohibition condition that makes it impossible to repeat a copy process is satisfied. Is related to a device that controls display when a predetermined prohibition notice condition is set to be permitted.

[Conventional technology]

If the copier becomes inoperable (for example, toner end, collected toner overflow, etc.) or warns that the copier will become inoperable soon (toner near end, collected toner overflow notice, etc.), the operation is started. The state was indicated by a display indicating the disabled state. As the display means, a display member such as an LED corresponding to each disabled state, an LCD display, a CRT display, or the like is used.

However, if a display member is provided for each abnormality, the operation panel becomes complicated. Therefore, it is preferable to display the abnormality information using a 2-digit or 3-digit 7-segment display such as a copy number display or a magnification display.

[Problems to be solved by the invention]

Since copying is impossible in the inoperable state, there is no problem if the copy number display is used for displaying the abnormality information. However, when a warning (notice) is given that the operation will be disabled shortly, copying is continued until the operation is disabled, so that the error information is displayed on the copy number display. Then, the operation becomes very troublesome, and there arises a problem that it is difficult to determine whether copying is possible or not and it is difficult to confirm the number of copies.

An object of the present invention is to simplify a display member of an operation panel and to solve the above-described problem.

[Means for solving the problem]

The first invention of the present application is a magnification input means (151 to 155) for inputting a copy magnification, a magnification display means (156) for displaying an inputted copy magnification, and a function according to the inputted copy magnification. Image forming means (100) for adjusting the optical scanning system (110) and executing the copy process at the copy magnification to form a copy of the original image, a predetermined prohibition condition for preventing the repetition of the copy process (recovery toner overflow) of before the establishment, notice condition detecting means repetition of copying processes for detecting the establishment of a predetermined prohibition notice condition (recovery toner near overflow) to soluble (12A _2, 12A _3, 403), and the prohibition condition (recovery The copy magnification input by the magnification input means (151 to 155) of the copying apparatus including the means (400) for prohibiting the start of the copy process in response to the establishment of the toner overflow is displayed on the magnification display means (156). Duplicate In magnification operation display device (150,400), with notice condition detecting means (12A _2, 12A _3, 403) is prohibited notice condition while not detecting the establishment of (recovered toner near overflow) magnification input means (151 to 155) The input copy magnification is displayed on the magnification display means (156), and the notice condition detection means (1
2A ₂ , 12 _A , 403), in response to the detection of establishment of the prohibition notice condition (recovery toner near overflow), magnification display means (156)
After the display is switched, the copy magnification is displayed while the magnification input means (151 to 155) is being input and while the optical scanning system (110) is being adjusted according to the copy magnification. Means (156) including a display control means (400) for switching and displaying.

According to a second invention of the present application, in addition to the first invention, the display control means (400) switches and displays the prohibition information on the display means (156) in response to establishment of a prohibition condition (recovery toner overflow). The display of the prohibition information is continued without responding to the input operation of the magnification input means (151 to 155).

In addition, the symbols or terms shown in parentheses indicate corresponding elements or corresponding items of the embodiment described later with reference to the drawings.

[Action]

According to the first invention of the present application, magnification display means (156)
Displays the copy magnification and the notice information, so that a separate display member for displaying the notice information is omitted, and the operation display panel is simplified.

Notice condition detecting means (12A _2, 12 _A, 403) detects a prohibition notice condition (recovery toner near overflow) met, when it is not a copy processing without magnification input, displays the the advance notice information magnification display means (156) Therefore, the operator first recognizes the notice information.

When the notice information is displayed, the number-of-copies display indicates the set number of copies or the number of copies that have been continuously repeated, so that the operator first determines that copying is permitted.
When the operator operates the magnification input means (151 to 155), the input magnification is displayed on the magnification display means (156).
Thus, the operator can easily recognize that the magnification can be input and that the input magnification has been set, and that the copying is possible.

Since the notice information is displayed on the magnification display means (156) in this way, the trouble of use is suppressed as compared with the case where the information is displayed on a copy number display or the like, and the function of the copy magnification display is sufficiently performed. A warning notice is displayed as required.

By the way, in the RAM of the main controller, an abnormal code buffer is provided as shown in FIG. 8, and when an abnormal code is displayed, a search is made from address 0 and a value other than 0 is contained in the buffer value. Displays its value. A two-digit code is used as the abnormality code, and “E” indicating an abnormality is displayed in the third digit. For example, at the time of the recovery toner overflow warning (overflow counter ≦ 250, abnormal warning mode), “70” is set, and the magnification indicator 156 is displayed on the magnification display 156.
"E70" blinks as shown in Fig. 4b.

FIG. 7 shows the clear control in the abnormal mode. Check the error code buffer sequentially to the end address (21). If all buffers are cleared (22), clear the error mode (23), clear the error warning mode (24), and return. . That is, when there is no abnormality in the apparatus, the display of the magnification display 156 is changed to the normal magnification display.

As described above, according to the present embodiment, when an abnormality warning is issued, an abnormality code is blinkingly displayed on the magnification display 156. The magnification is displayed, and when the setting of the optical system according to the magnification (movement of the lens 114 and the third scanner motor) is completed, the abnormal code is blinked again.
In the case where the abnormality is prohibited, the abnormality code is continuously displayed, and even if there is a change input of the magnification display, it is not accepted.

In this embodiment, the mode is switched to the abnormal warning mode or the abnormal mode by checking the amount of collected toner. However, the abnormal warning mode is set when the toner is near the end, and the abnormal mode is set when the toner is ended. For example, it is possible to respond to a toner near-end abnormality warning display.
