Description

[Detailed description of the invention] [Field of industrial application] The present invention is a paper tray display device for a copying machine, and more specifically, a paper tray display device for a copying machine, and more specifically, a state in which it is possible to see at a glance whether or not there is a paper tray containing paper of a desired size and the position of the paper tray. The present invention relates to a paper tray display device that displays a paper tray display device.

[Conventional technology]

The paper size display method in conventional copying machines is as follows:
Most of them display the paper size of the paper stored in a selected tray.

FIG. 3 shows an example of a conventional paper tray display device for a copying machine.

In the figure, 30 is a display panel, and the display panel 3
A paper size display 31 is disposed on the left side of 0, a tray display 32 is disposed in the center, and a tray display 33 and a tray selection key 34 are disposed on the right side. Then, when the operator presses the tray selection key 34,
The tray indicator 32 indicates TRAY,...
... will light up in sequence, for example as shown in the figure.
When A3 size paper is stored in TRAY,
The tray indicator 32 of the TRAY and the A3 paper size indicator 31 light up at the same time, making it clear that A3 paper is stored in the TRAY.

[Problems that this invention attempts to solve]

However, in the conventional structure described above, when the paper size indicator of the desired paper does not light up, the tray selection key 34 is continuously pressed to check whether or not paper of the desired size is stored in the other trays one by one. I had to check it out. Moreover, even if the tray containing a desired size of paper is found on the tray display 32, the position of the tray in the copying machine cannot be immediately determined, and tasks such as replenishing paper or removing jammed paper cannot be immediately determined. It was inconvenient when working.

The present invention aims to solve the above problems.

[Means for solving problems]

In order to achieve the above-mentioned purpose, the paper tray display device for a copying machine of the present invention includes a plurality of paper display devices respectively attached with characters indicating different paper sizes, and among the plurality of paper display devices, the copying machine The paper indicators corresponding to the sizes of the paper stored in the plurality of paper trays set in the printer are all lit at the same time at all times, and the paper indicators arranged corresponding to each of the plurality of paper trays are selected. a plurality of paper selection indicators that are lit all at once; a paper selection key that sequentially changes the lighting position of the plurality of paper selection indicators for each operation to select paper of a desired size;
and a plurality of tray set position indicators provided in a tray location display section in which the positions of the plurality of paper trays are graphically displayed, and whose display is switched in conjunction with the display of the plurality of paper selection indicators. Features.

[Effect]

In this invention, when starting copying,
All available paper sizes are displayed simultaneously at all times. Therefore, the user can determine at a glance whether copying can be performed using paper of the desired size. Furthermore, since the position of the paper tray containing the paper to be used is displayed graphically, countermeasures can be easily taken when a problem such as a paper cut or a paper jam occurs.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 is a plan view of a paper tray display device according to the present invention, and FIG. 2 is a plan view of a copying machine equipped with this display device.

As shown in FIG. 2, a platen cover 1, an operation panel 2, and a paper tray display device 3 are disposed on the top surface of the copying machine A.

As shown in FIG. 1, on the left side of the paper tray display device 3 are paper indicators 4, 5, 6 that display the characters "A3, B4, A4, B5, and others" indicating the size of the copy paper. , 7, and 8 are disposed, and a paper selection key 14 for lighting paper selection indicators 9, 10, 11, 12, and 13 using light emitting diodes is further disposed on the left side thereof.

A tray location display section 15 is provided on the right side of the display device 3, and displays a copying machine diagram 16 and tray diagrams 17, 18, and 19 showing the set positions of the trays in the copying machine. Indicators 20, 21 and 22 are arranged on the tray pictures 17, 18 and 19.

The present invention has the above-mentioned configuration, and the trays in the copying machine A have A3 size and A4 size, respectively.
and B5 size paper is stored.
Paper indicator lamps 4, 6 and 7 are lit.

Therefore, each time the paper selection key 14 is pressed once, the paper selection indicators 9, 11, and 12 light up in sequence.

In other words, A3 size paper in the tray and A4 size paper in the tray.
If B5 size paper is stored in the tray, by pressing the paper selection key 14, the display 9, A3 size paper display 4, and tray picture 17 display 20 will be displayed at the same time. The lamp lights up (see Figure 1), allowing you to instantly know that A3-sized paper is stored in the tray of copying machine A and the position where the tray is set.

Similarly, when paper selection key 14 is pressed, display 1
1. The A4 size paper display 6 and the display 21 of the tray picture 18 light up at the same time, and the display 12,
The B5 size paper display 7 and the tray picture 19 display 22 are turned on at the same time.

Note that when replenishing paper or when a paper feeding error occurs due to a paper jam or the like, it is possible to easily determine whether there is an abnormality in the paper tray from the lighting relationship of the above-mentioned display or the like.

[Effect of idea]

As explained above, the present invention has the following effects.

(i) The size of paper stored in all trays of the copying machine can be immediately seen at a glance.

(ii) The setting position of the tray containing paper of a desired size can be immediately determined.

(iii) Absence of paper and abnormalities such as paper jams can be immediately determined.

(iv) If an abnormality occurs due to paper replenishment or paper jams, it can be dealt with immediately.
