Accordingly, even if at least the part of the sheet transporting passage is not included in the enclosure and the another sheet transporting device, when the another sheet transporting device is attached to the enclosure, the sheet transporting passage is constructed, and accordingly, the sheet transporting device can be miniaturized.
[0013] According to another aspect of the present invention, an image forming apparatus includes an enclosure including a first guide part at least a part of which can be exposed to outside, wherein a sheet transporting device is attached to the enclosure, the sheet transporting device includes a second guide part at least a part of which is exposed to outside, and at least a part of a sheet transporting passage includes the first guide part and the second guide part. Accordingly, even if at least the part of the sheet transporting passage is not included in the sheet transporting device to be attached to the enclosure, when the another sheet transporting device is attached to the enclosure, the sheet transporting passage is constructed, and accordingly, the image forming apparatus and the sheet transporting device can be miniaturized.
[0014] According to another aspect of the present invention, an image forming apparatus includes an enclosure including a first guide part at least a part of which can be exposed to outside, and a sheet transporting device to be attached to the enclosure, wherein the sheet transporting device includes a second guide part at least a part of which is exposed to outside, and at least a part of a sheet transporting passage includes the first guide part and the second guide part. Accordingly, even if at least the part of the sheet transporting passage is not included in the enclosure and the sheet transporting device, when the sheet transporting device is attached to the enclosure, the sheet transporting passage is constructed, and accordingly, the image forming apparatus and the sheet transporting device can be miniaturized.

Problems solved by technology

However, when a sheet transporting passage is formed in a sheet transporting device, there is a case where the sheet transporting device can not be miniaturized.
Besides, when the sheet transporting passage is formed in the sheet transporting device, in a case where the sheet transporting device is attached around the image forming apparatus main body, there is a case where the image forming apparatus can not be miniaturized.

first embodiment

[0027] the present invention will be described with reference to the drawings.

[0028]FIG. 1 shows the outline of an image forming apparatus 10 according to the first embodiment of the invention. The image forming apparatus 10 of the first embodiment includes an image forming apparatus main body 12, a detachable cover 13 provided at an upper part of the image forming apparatus main body 12, and a passing port 14, through which a sheet passes, provided at a lower part of a back side (right side of FIG. 1) of the image forming apparatus main body 12. Besides, an opening / closing cover 16 rotatable around a rotation fulcrum 15 is provided at the upper part of the image forming apparatus main body 12, and for example, a one-stage sheet supply unit 18 is disposed at the lower part of the image forming apparatus main body 12.

[0029] The sheet supply unit 18 includes a sheet supply unit main body 20 and a sheet supply cassette 22 in which sheets are stored. A feed roll 24 for feeding sheets f...

second embodiment

[0065] Next, the invention will be described with reference to the drawings.

[0066]FIG. 9 shows the outline of an image forming apparatus 10 according to the second embodiment of the invention.

[0067] Incidentally, in the image forming apparatus 10 of the second embodiment, substantially the same parts as those of the image forming apparatus 10 of the first embodiment are denoted by the same reference numerals.

[0068] In the image forming apparatus 10 of the second embodiment, a transport part 148 rotatable around a rotation fulcrum 146 is provided at an upper part of an image forming apparatus main body 12.
