BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jam processing display device for paper handling equipment such as copying machines, printers, and facsimiles.

0002

[Prior Art] Generally, in this type of equipment, it is impossible to completely eliminate paper jams, and when a jam occurs, follow the guidance display for the location of the jam displayed on the operation panel. I try to find and operate the knobs and levers for removing jammed paper to remove jammed paper.

0003

[Problem to be Solved by the Invention] When using such jam handling measures, if the user is familiar with the machine,
Although such a guidance display for the jam location is enough to deal with the problem, it is inconvenient for general users who are inexperienced. In other words, the guidance display for the jam location makes it difficult to understand which knobs and levers to operate, and in reality, users end up operating unrelated knobs, etc., resulting in repeated trial and error, resulting in wasted work. be. In addition, the work is generally performed inside the machine, and depending on the location of the jam, the operation may be near high-temperature parts such as the fusing unit, so general users may be concerned about damage to the equipment or fear of danger. There are many cases where jams occur, and it is important from a safety perspective to clearly indicate the jam location or operation. Furthermore, for unaccustomed users, a simple jam indication may not be enough to quickly resolve the issue and may lead to the assumption that there is a malfunction, resulting in frequent service man calls, which results in loss of time when the machine cannot be used. It becomes long.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be explained based on the drawings. This embodiment is applied to a copying machine, and FIG. 2 shows the appearance of the copying machine 1. This copying machine 1 is equipped with an ADF 3 for automatically transporting a document on a main body 2, and an operation panel section 5 equipped with a full-dot liquid crystal display section 4 is provided on the front side of the top surface. Further, in addition to a paper feed cassette provided inside the main body 2, a large paper feed cassette section 6 is provided on the right side, and a paper discharge section 7 with a sorter function is provided on the left side. Furthermore, in front of the main body 2, there is a front cover 8 that is opened and closed for maintenance, jam removal, etc.
is provided.

Although the internal structure of such a copying machine 1 is not particularly shown, as is well known, the transfer paper fed from the internal cassette or the paper feed cassette section 6 is transferred through the photoreceptor transfer section, and then fixed. A conveyance path (not shown) is formed for fixing the paper through the copying section and discharging the paper to the paper discharging section 7, as well as for storing the paper once in the duplex tray, refeeding the paper, making a back side copy, and discharging the paper as necessary. ing. Each part of the conveyance path, such as the paper feed section, transfer section, double-sided tray section, and paper ejection section, is equipped with a detection means to detect if the transfer paper is not being conveyed normally and jams. A plurality of sensors S1, S2, ~, Sn are provided (Fig. 1(b)
)reference). On the other hand, when a transfer paper jam occurs, a part of the conveyance path is opened to take out and remove the jammed paper, and a roller is rotated to manually convey the jammed paper.
A plurality of jam handling operation units are also provided to perform opening/closing, rotation, and other operations.

This point will be explained with reference to FIG. 3, which shows jam processing when a jam occurs near the transfer section. Main body 2
When a jam occurs inside the printer, first open the front cover 8 as shown in FIG. Next, in order to open a part of the conveyance path, the lever 9 is rotated and lowered in the direction of the arrow, as shown in FIG. 2(b). Thereafter, the jammed transfer paper 11 is manually conveyed and removed by rotating the knob 10 in the direction of the arrow as shown in FIG. Therefore, in this case, the lever 9 and the knob 10 serve as the jam handling operation section.

[0013]In this embodiment, therefore, each of the jam handling operation parts such as the lever 9 and the knob 10 is provided with built-in LEDs 1 to LEDn serving as light emitting elements. FIG. 1A shows a state in which, for example, an LED 1 is embedded in the lever 9, and is connected to the controller side by an electric wire 12.

These LED1 to LEDn are shown in FIG. 1(b).
As shown in FIG. 2, they are connected to a controller 13 serving as a control means, and are individually controlled to blink or emit light. The sensors S1 to Sn are also connected to this controller 13,
The CPU in the controller 13 is configured to check the on/off status of these sensors S1 to Sn at preset timings to perform jam detection, which determines whether or not a jam has occurred and the location where the jam has occurred. In addition,
The controller 13 is connected to an AC power source via a DC power source 14, and is also connected to the liquid crystal display section 4.

In such a configuration, since the transfer paper 11 is present in the conveyance path when a jam occurs, one of the sensors S1 to Sn is always in the ON state. Utilizing this fact, the jam location can be identified when a jam occurs. To explain the control by the controller 13 with reference to the flowchart shown in FIG. 4, first, the ON/OFF state of the sensor S1 is checked, and the blinking of the LED1 for the jam processing operation section corresponding to the sensor S1, here the lever 9, is explained. Determine whether or not. If the sensor S1 output is on, this L
Make ED1 blink. That is, in the example shown in FIG. 3, this LED 1 on the lever 9 flashes, and the operator is informed that this lever 9 should be operated to clear the jam. Similarly, on/off for sensors S2 to Sn
The off-check is performed in the same way, and if any of the LEDs is turned on (jam detected), the corresponding LED2 to LEDn are blinked to notify that the jam processing operation unit to which the LED is attached should be operated. Therefore, in the example of FIG. 3, the LED 2 attached to the knob 10 also flashes. If the sensors S1 to Sn are off, the corresponding LEDs remain off.

The processing shown in FIG. 4 is performed until the jam processing is completed.
Since this process is constantly repeated, when the jammed transfer paper 11 is removed, the corresponding sensor also returns to the OFF state, so the blinking LED also returns to the OFF state, and the completion of the jam processing is notified.

Although it is easier to alert the operator when the LED1 to LEDn are blinking, they may also be light-emitting displays.

Further, in this embodiment, in parallel with such processing, when the occurrence of a jam is detected by any sensor S, under the control of the controller 13, the liquid crystal display section 4 displays the image shown in FIG. As shown in FIG. 1, a jam display pattern 16 (conveyance route pattern, classification of jam processing locations as shown by A to E, and display of jam occurrence locations) including a jam mark 15 is displayed. Therefore, when a jam occurs, the operator sees the jam display pattern 16 to know the occurrence of the jam and its approximate location, and then, as shown in FIG.
When opened, the LED flashes or emits light at the jam location, directly indicating the jam removal operation section to be operated, resulting in good jam removal performance.

[0019]

[Effects of the Invention] As described above, the present invention provides a light emitting element for each jam handling operation section, and responds to jam locations detected by a plurality of detection means for detecting paper jams at various locations on the conveyance path. Since a control means for blinking or emitting light from the light emitting element of the jam handling operation unit is provided, when a jam occurrence is detected, the jam handling operation unit that should be operated in accordance with the location where the jam has occurred among the many jam handling operation units is activated. This will be clearly indicated by flashing or emitting light from the light emitting element, and direct jam removal information will be provided, so even general users will be able to clearly identify the target of the jam removal operation, allowing them to easily remove the jam without worrying about erroneous operations. Become something. In addition, by displaying the jam location on the operation panel in addition to the display using a light emitting element on the jam processing operation section that should be operated, the display from jam occurrence to jam removal becomes clearer, making it easier to deal with the jam. Become something. Furthermore, by canceling the display by the light emitting element after the jam removal, the operator can be reliably informed of the end of the jam removal.
