Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display control device of a copying machine having an automatic paper selection mode.

2. Description of the Related Art In recent years, in a copying machine, display contents on an operation display unit have become complicated due to enlargement of a copy function, and display on a display unit which is unnecessary in a copy mode is performed.

Problems to be Solved by the Invention In the copy mode, the display on the display unit which is unnecessary is performed, so that the improvement of the operability of the operator is hindered,
It also causes a malfunction.

Means for Solving the Problems A plurality of paper feed trays accommodating transfer paper for each size, and a tray display unit corresponding to these paper feed trays, and transfer of an optimal size from a document size and a copy magnification. In a copying machine having an automatic paper selection mode for automatically selecting the paper supply tray in which paper is stored, a user selects whether or not to erase all indications on the tray display unit in the automatic paper selection mode. A tray display erasing means, wherein the remaining amount of the transfer paper stored in the paper feed tray selected when the display in the tray display section is completely erased and the copying is performed in the automatic paper selection mode is equal to or less than a set number of sheets. And an erasure canceling means for canceling the erasure of the display of the tray display section corresponding to the selected paper feed tray when the number of sheets has decreased.

When a mode in which all the displays on the tray display section are erased by the tray display erasing means is selected, all the displays on the tray display section which are unnecessary for the operation when copying in the automatic paper selection mode are erased. In addition, when a mode in which the display on the tray display section is entirely erased by the tray display erasing means is selected, and when copying is performed in the automatic paper selection mode, the remaining amount of transfer paper in the selected paper feeding tray is selected. When the number of sheets becomes equal to or less than the set number, the display erasure of the tray display section corresponding to the selected paper feed tray is released by the erasure canceling means, and the tray display section corresponding to the selected paper feed tray is displayed. Notifies that the transfer paper is low.

Embodiment An embodiment of the present invention will be described with reference to the drawings. First,
Second system configuration of copying machine using micro CPU1
Shown in the figure. That is, the micro CPU 1 executes the program of the copying machine as a control means, and the ROM 3, RAM 4, and the nonvolatile memory storing the control program via the address, data and control bus line 2.
RAM5, input / output port 6, and serial communication control unit 7
Is connected. The input / output port 6 is connected to an output load such as a motor and a solenoid in the copying machine and an input source such as a sensor. An operation display unit 8 for transmitting and receiving signals via the unit 7 is connected to the serial communication control unit 7.

Next, the tray display control device 9 in the copying machine will be described with reference to FIG. First, the copier has a first paper feed tray 10 for storing A3 size transfer paper (not shown) and a second paper feed tray 11 for storing A4 size transfer paper (not shown). And a third paper feed tray 12 for storing B4 size transfer paper (not shown), and a fourth paper feed tray 13 for storing B5 size transfer paper (not shown). . As shown in FIGS. 4 to 6, the operation display section 8 includes tray display sections 14 to 17 corresponding to the paper feed trays 10 to 13 and a magnification display section for displaying the magnification of copying. 18 and so on are provided. The tray display control device 9
The transfer paper size information and transfer paper remaining amount information of the transfer paper stored in the paper feed trays 10 to 13 are input, and further, information as to whether or not the automatic paper selection mode is selected and the tray Information as to whether or not a mode for deleting the display of the tray display sections 14 to 17 has been selected by display deletion means,
Information on whether or not the paper feed trays 10 to 13 to be used are selected is input, and the display of the tray display units 14 to 17 is determined based on the information.

With reference to FIG. 1, a description will be given of a case in which copying is performed by selecting a mode in which all displays on the tray display sections 14 to 17 are selected by the tray display erasing means in such a configuration. When the start button for starting copying is pressed, it is first determined whether or not the mode is the automatic paper selection mode. If the mode is not the automatic paper selection mode, the mode for clearing the display of the tray display sections 14 to 17 is released, and further, as shown in FIG. The tray display section 15 corresponding to the tray 11) is displayed separately from the other tray display sections 14, 16 to 17.

Next, when the automatic paper selection mode is selected, it is determined whether or not the transfer paper to be used and the paper tray in which the transfer paper is stored are selected based on the document size and the copy magnification. . Before selection, the tray display section 14
17 are maintained in the display erased state as shown in FIG.
In the automatic paper selection mode, the operator does not need to select the paper feed trays 10 to 13;
Even if the displays of Nos. To 17 are erased, there is no operational trouble. In addition, since the displays on the tray display sections 14 to 17 that are unnecessary for the operation are deleted, the operation display section 8 is easy to see, and the operability when operating another display section is improved.

After the paper feed tray that stores the transfer paper to be used is selected, it is determined whether the remaining amount of transfer paper in the paper feed tray has decreased to a set number or less. When the remaining amount of the transfer paper in the selected paper feed tray is equal to or more than the set number, the tray display units 14 to 17 are kept in the display erasing state.
On the other hand, the selected paper tray (for example, the second paper tray)
When the remaining amount of the transfer paper in 11) becomes equal to or less than the set number, the display erasure of the tray display unit 15 corresponding to the selected paper feed tray 11 is released by the erasure release means, and the sixth release is performed.
As shown in the figure, the display on the tray display section 15 is performed. Thereby, the operator can know that the remaining amount of the transfer paper in the selected paper feed tray 11 has decreased to the set number or less, and prepares additional transfer paper before the transfer paper is completely exhausted. The efficiency of copying work is improved.

Advantageous Effects of the Invention The present invention is unnecessary for the operator's operation when the mode for erasing the display on the tray display section by the tray display erasing means is selected and the automatic paper selection mode is selected as described above. Can be copied in a state where the display of the tray display section is erased, so that operability of the operator can be improved and erroneous operation can be prevented, and furthermore, When the remaining amount of transfer paper is reduced to the set number or less, the display erasure of the tray display section corresponding to the selected paper feed tray can be canceled by the erasure canceling means. Can be notified that the remaining amount of transfer paper in the paper feed tray has become low, and by preparing additional transfer paper before the transfer paper is completely exhausted, the copying operation can be efficiently performed. And the like can be improved.
