  According to a tenth aspect of the present invention, in the image forming apparatus according to the tenth aspect, a gel ink jet type image forming section is provided.

  According to the paper discharge unit structure and the image forming apparatus of the image forming apparatus according to the present invention, it is possible to form a wide paper take-out opening in a narrow in-body paper discharge unit with a simple configuration.

  Embodiments as the best mode for carrying out the present invention will be described below with reference to the drawings.

  1 is a perspective view of the image forming apparatus according to the embodiment, FIG. 2 is a front view of the image forming apparatus shown in FIG. 1, and FIG. 3 is a side view of the image forming apparatus shown in FIG.

  As shown in FIGS. 1 to 3, the image forming apparatus 100 includes an image forming unit 110 having a gel ink jet image forming apparatus, and four paper feed trays 121 and 122 arranged below the image forming unit 110. , 123, and 124, an image reading unit 130 provided above the image forming unit 110, and a paper discharge unit provided between the image forming unit 110 and the image reading unit 130. 140. The image forming unit 110 and the image reading unit 130 include a left side connecting unit 150 that connects the left side of the image forming unit 110 and the image reading unit 130, a back side connecting unit 160 that connects the back side, and a front right side. A right connection part 170 to be connected and an operation part 180 are provided.

  Next, the structure of the paper discharge unit 140 of the image forming apparatus according to this example will be described. 4 is a plan view showing a closed state of the paper discharge unit door of the image forming apparatus shown in FIG. 1, FIG. 5 is a perspective view showing a closed state of the paper discharge unit door of the image forming apparatus shown in FIG. FIG. 7 is a plan view showing an open state of a paper discharge unit door of the image forming apparatus shown in FIG. 1, and FIG. 7 is a perspective view showing an open state of the paper discharge unit door of the image forming apparatus shown in FIG. In each figure, the automatic document feeder of the image reading unit is shown removed.

  In this example, an opening for taking out the paper in the image forming device 111 of the image forming unit 110 is provided at a position below the paper discharge unit 140 and forming the upper wall of the image forming unit 110 as shown in FIG. A portion 230 is formed.

  And this opening part 230 is covered so that opening and closing is possible with the door apparatus 200, as shown in FIG.4 and FIG.5. The door device 200 is configured such that the right door member 210 and the left door member 220 made of a transparent or translucent synthetic resin have a double door opening. The right door member 210 and the left door member 220 overlap with each other in the closed state and completely cover the opening 230 to form the bottom wall of the paper discharge unit 140.

  As shown in FIGS. 6 and 7, the right door member 210 rotates upward about a hinge portion 211 provided at the left edge of the opening 230. Further, the left door member 220 is pivoted about a first door member 221 that pivots upward about a hinge portion 224 provided at the right edge of the opening 230 and a shaft 223 at the tip of the first door member 221. It is comprised with the 2nd door member 222 attached so that it was possible.

  In this example, the first door member 221 is configured to completely collapse to the right side in the open state. In this example, a guide rail 250 having a predetermined shape is provided in the back side connecting portion 160 to guide the tip of the first door member 221 of the left door member 220. For this reason, the left door member 220 is always guided by the guide rail 250 and opens and closes with the same locus. Further, as shown in FIG. 7, the guide rail 250 stably fixes the left door member 220 so that the opening 230 is opened when the left door member 220 is in the open state.

  Therefore, according to this example, the sheet passing state of the image forming device 111 can be confirmed through the right door member 210 and the left door member 220 constituting the door device 200, and the door device 200 can be opened as a double door. Since the left door member 220 is composed of the first door member 221 and the second door member 222 and is guided by the guide rail 250, a large opening 230 can be formed in the paper discharge unit 140, and the door device 200 is opened. In this case, the right door member 210 and the left door member 220 are kept open, so that the door device 200 does not get in the way when performing operations such as taking out paper from the image forming device 111.
