DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as a printer and a copying machine using an electrophotographic system.

[0002]

2. Description of the Related Art Conventionally, for example, in a copying machine using an electrophotographic method, when a transfer material is clogged in a main body during operation,
On panel A which displays the position of a paper jam as shown in FIG. 4 (a), the LED of the number where the paper jam has occurred is turned on, and the operator can look up the numbered lever or knob in the main body. It has been practiced to operate the levers and knobs to remove jammed paper.

For example, FIGS. 4 (b) and 4 (c) are perspective views of the main part of the main body of the copying machine, and if the LED of FIG. In the main body, find the release lever 1 numbered with).
By operating as shown in (b) and FIG. (c), the transfer material causing the paper jam was removed.

[0004]

However, in the above conventional example, it is necessary to look at the panel A as shown in FIG. 4 (a) first, and then search for a lever or a knob to be actually operated. However, there is a problem that the operation method of the lever is difficult to understand, and that the operator forgets to return the lever.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an image forming apparatus provided with an operation member which can be easily and reliably operated at the time of a paper jam and having improved operability.

[0006]

In order to achieve the above object, according to the present invention, an operation member for releasing a transport path when a paper jam occurs in the transport path is provided at a plurality of positions on the transport path. In the image forming apparatus provided in the above, in which of the plurality of places the paper jam has occurred ,
The operation direction of the operation member and the paper jam were removed.
Display member for indicating the operation direction of the operation member at the time of
And characterized in that provided in each of said operating member.

Further , the display member is provided in front of a paper jam.
When the operation direction of the operation member is displayed and a paper jam is removed
Display of different colors with the display of the operation direction of the operation member
It is preferable that the operation member is a lever.
Preferably, the display member has an arrow shape.

[0008]

According to the present invention having the above-described structure, when a paper jam occurs in the transport path, the display member provided on the operation member displays the location where the paper jam has occurred and the operation member at the time of the paper jam.
Operation direction and the operation members when the paper jam is removed.
The operation direction is notified.

When the display member also displays the operation method and operation status of the operation member, the operability of the operation member is improved.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. (First Embodiment) FIG. 1A is a schematic sectional view showing an image forming apparatus according to the present invention. In a copying machine using an electrophotographic method, a place where a paper jam may occur is a paper feeding unit E, a separation / feeding unit. One of the four blocks of the transport unit F, the fixing and discharging unit G, and the duplex unit H.

FIGS. 1 (b) and 1 (c) show a separating / transporting section F.
5 is a perspective view showing the removal of a paper jam in FIG. 5, and the lever 1 as an operating member is tilted to the right to widen the conveyance path 2 of the separation / conveyance unit F to release the paper jam and remove the paper jammed transfer material P.

FIG. 2 is a view showing the state of the lever 1. The lever 1 has an arrow-shaped display member 3 oriented in the operation direction.
The lighting, blinking, and extinguishing can be arbitrarily performed as needed. (Note that each timing is determined by a signal from a controller (not shown) for controlling the copying machine.) If a paper jam occurs in the transport path 2 of F while the copying machine is operating, first, copying is performed. The machine automatically shuts down and issues a message to the operation section (not shown) saying "Please open the front door and remove the paper jam." Then, the display member 3 of the lever 1 of the separation / conveyance unit F where the paper jam has occurred changes from the state shown in FIG. 2A to the state shown in FIG. 2B. Thus, the operator can know at a glance where to operate by opening the front door (not shown) of the apparatus main body.

Further, since the display member 3 has an arrow shape, it is possible to know an operation method in which direction to operate. Then, the operator tilts the lever 1 clockwise in accordance with the light-on display of the display member 3 and removes the sheet material that has caused the paper jam, and the display member 3 then blinks from the light-on state as shown in FIG. Change to a state,
The operator is notified to return the lever 1 to the original position.
Then, when the lever 1 is returned to the original position, the display member 1a is turned off as shown in FIG. This is very effective in preventing the operator from forgetting to return the lever 1.

Of course, when a paper jam has occurred at a plurality of locations in the transport path, a display member similarly incorporated in the lever is turned on at that location, prompting the operator to perform processing.

Therefore, when a paper jam occurs, the operator opens the front door and moves the lit lever in the direction of the arrow indicated by the display member to remove the jammed sheet material, and all the blinking of the display member at each position is turned off. By returning the levers as described above, the processing can be surely completed.

This eliminates useless operations and operational errors and improves operability.

Next, another embodiment of the present invention will be described. The same components as those in the first embodiment will be described with the same reference numerals. (Second Embodiment) FIG. 3 is a view showing a second embodiment of the present invention, and shows a state of a lever and a state of a display member similarly to the first embodiment. The difference from the first embodiment is that an arrow-shaped display 3b in the returning direction is increased, and the display 3b is
The display member 3 is composed of an arrow-shaped display 3a oriented in the operation direction.

When a paper jam occurs and the display 3a is turned on (FIG. 3B), the operator operates the lever 1 according to the display 3a.
To the right and remove the jammed sheet material. Then
Display 3a is turned off, indicating the return direction of the lever 1 Display 3 b is lit (Figure 3 (c)). When lever 1 is returned, display 3a,
The display 3b is turned off (FIG. 3 (d)) . This is more effective in forgetting to return the lever. Third Embodiment In FIG. 3, if the display 3a is classified into blue and the display 3b is classified into red, the operation status can be identified at a glance even when operating a plurality of levers, and the operability is further improved. Can be improved.

[0019]

According to the present invention having the above-described structure, when a paper jam occurs in the transport path, the position of the paper jam occurrence is determined by a display member provided on the operation member .
It is possible to know the operation direction of the operation member. Furthermore, paper
The display shows the lever operation direction when the jam is removed.
Display member, you may forget to return the lever.
In that respect, operability is greatly improved in that respect.

Further, the operability of the operation member can be improved by displaying the operation method and the operation state of the operation member on the display member.
