<Prior art> When a copying machine attempts to copy onto paper of a desired size,
A sheet of paper of that size is set in the paper feed section, and this sheet is fed to a transfer position, etc. that faces the recording medium. in this case,
A large number of sheets are stored in a paper feed cassette, a paper feed tray, or the like for automatic paper feeding. By attaching such a paper feeding cassette to the copying machine main body, paper of a desired size is automatically fed. Conventionally, multiple types of cassettes are installed in the copying machine body in advance, and the user selects the desired paper size to automatically feed the paper that the user needs. Copying machines that can be equipped with cassettes have had problems dealing with paper jams in the paper feed section. Particularly, if jammed paper remains in the paper feed cassette, the jammed paper can be easily removed by pulling out the attached paper feed cassette. In this respect, if the jammed paper is not in the paper feed cassette, the paper cannot be removed even if the cassette is pulled out as described above.

For this reason, there are shell-type copying machines in which the main body of the copying machine is divided into upper and lower parts along the paper transport path.In this case, jammed paper can be easily removed by opening the top and bottom of the copying machine centering on one fulcrum. can. However, in a copying machine equipped with a large number of cassettes, jammed paper cannot be handled simply by opening the main body of the copying machine vertically. In other words, even if the copying machine main body is opened vertically, only the transport path for paper in one cassette can be opened, but jammed paper in other transport paths cannot be removed. In order to solve this problem, the paper feed section where the cassette is installed is made into a unit, and by pulling out this paper feed unit, the jammed paper in that section can be handled. Since the cassette (tray) is fixed to the main body of the copying machine, it is difficult to clear the jam from outside, and it is necessary to clear the jam from inside the machine. Therefore, if a jam occurs between the paper feed roller facing the cassette and the conveyance path to the transfer position to the photoconductor, the first step to making this jam removal easier is to create a paper feed unit or increase the vertical opening angle. , it was necessary to set a large space in advance between the guides for the transport path fed from the cassettes of each stage. In particular, with copying machines equipped with multi-stage cassettes and large-capacity cassettes, the number of paper conveyance paths from each stage increases, making the structure complex. Furthermore, space for handling jams is also required, so the feeding section is This leads to an increase in the size of the aircraft.

Furthermore, according to a copying machine equipped with a double-sided copying function, the paper that has been copied on one side is temporarily stored in an intermediate tray, and the paper in this tray is fed to perform the above-mentioned paper feeding and paper transport from the cassette. It merges with the path and is conveyed to the transfer position. In order to facilitate the handling of paper jams in such a conveyance path, the conveyance system for the duplex copying section is made into a unit, and this unit is structured to be pulled out. The structure in which the transport system for double-sided copying is made into a unit and the unit can be pulled out is extremely complicated.

On the other hand, not only paper jams from the above-mentioned paper feed rollers 2.3.4, but also paper jams from the intermediate tray 19 to the transfer position may be handled in the same manner as described above. For example, after opening the copying machine main body, first the guide plate 30 is opened, and then the guide plate 34 is manually opened to the position shown by the broken line. As a result, the conveyance path 39 is also opened, and the jammed paper traveling from the intermediate tray 19 toward the synchronous roller 8 can be easily removed. Even in this case, even if the paper feeding system unit including the intermediate tray 19 is not provided in a removable manner, the copying machine according to the present invention can prevent paper jams from occurring along the conveyance path that conveys the paper to the transfer position. can be opened and closed vertically, and a guide member that forms a conveyance path separate from the above for conveying the feeding paper to the transfer position is configured to open in the same direction as the opening direction of the copying machine main body. Therefore, by opening the top and bottom of the copying machine main body, it is not only possible to clear jams in each transport path very easily, but also without increasing the opening angle of the copying machine main body, and by widening the space between each transport path. Since there is no need for any settings, the paper feeding section can be significantly downsized, and the overall size of the copying machine can be downsized.

Also, for paper fed from the intermediate tray for double-sided copying, it is only necessary to provide a guide member that can be opened and closed in order to open the conveyance path, and all members including this guide member can be opened and closed. Since the direction is the same as the opening and closing direction of the copying machine main body, the opening space of the guide member can also be enlarged, making it easier to clear the jam.
