Embodiment 1

[0063] figure 2 and 3 Example 1 of the image forming apparatus used in the present invention is shown.

[0064] exist figure 2 and 3 Among them, the imaging device has a device body 110 forming a device housing.

[0065] In this embodiment, the device body 110 includes: a box body 111, which serves as a device housing of a standard specification; An optional unit 112 in the lower part of the box body 111 .

[0066] In this embodiment, the imaging device 120 is housed in the box 111 of the device body 110 . A paper discharge portion 130 for receiving discharged paper is provided at the top of the cassette body 111 . For example, the two-stage sheet feeding unit 20 (specifically, 20 a and 20 b ) provided as a unit of standard equipment is provided in the lower portion of the cassette body 111 , that is, below the image forming section 120 .

[0067] Inside the apparatus body 110 (cassette body 111 and optional unit 112) is provided a paper conveyance path 36 for conveyi...

Embodiment 2

[0147] Figure 11 is an explanatory diagram showing important parts of the imaging device according to Embodiment 2 of the present invention.

[0148] exist Figure 11 The basic configuration of the image forming apparatus is basically the same as that according to Embodiment 1, except for the interlock mechanism 270 for detecting attachment / detachment of the paper cassette 22 of the paper feeding unit 20 . Incidentally, the same constituent parts as in Embodiment 1 are denoted by the same reference numerals as in Embodiment 1, and thus detailed descriptions of these parts will be omitted here.

[0149] That is to say, if Figure 11 , 12A As shown in and 12B, the interlock mechanism 270 used in this embodiment includes: a rocker 272, which is arranged on one side of the device body 110 across the position of the paper cassette 22 of the paper feeding unit 20 (20a to 20d). On the side, that is: it can rotate around the fulcrum 271 located at the lower end: the joints 273 to...
