Definitions
- the present invention relates to an apparatus having an original transport mechanism, and more particularly to an apparatus having an original transport mechanism such as an image reading apparatus and an image forming apparatus suitable for saving space in an office or a room.
- an original transport mechanism such as an image reading apparatus and an image forming apparatus suitable for saving space in an office or a room.
- Conventional image reading devices include an automatic document feed (ADF) type, a flatbed type, and a combined type of both.
- ADF automatic document feed
- Figure 1 shows a flatbed evening image reader that is often used by individual users.
- This flatbed type image reading device puts an original on the original glass 7 2, covers the original with the original holding cover 7 1, and puts a switch (not shown) on the scanning head (carrier) 7 3 Move back and forth to sequentially read the image of the original on the original glass 72.
- the work area is only the top surface and the office space can be used relatively widely, but the manuscript must be set one by one, and the work efficiency is poor. In addition, it is necessary to set the original and operate the device each time. Yes, the front work area must be open.
- Fig. 2 shows a combined image reading device of the ADF type and the flatbed type. This type of equipment is generally widespread.
- the originals are put together on a hopper section 74, the originals are sent by a transport section 76, and the originals are read by an image reading section 73.
- the manuscripts that have been read are discharged to the scanner unit 75 and are sequentially stacked and accumulated.
- This device is very efficient because multiple documents are automatically fed and processed automatically.

- the height of the part D is large so that a large number of originals 6 can be loaded.
- the transport route is extended to the side, passing through the reading section 3, and the scanning of the original 6 provided at the highest possible position.
- the U-shaped original transport bus is simply extended to the height H3
- the radius of curvature at the reversal portion becomes smaller, and the user wants to transport it using this device.
- the transport route is passed from the document stacking section D, through the feed roller 31 and the separate roller 32, to the next feed roller 33, the reading section 3, and the platen roller 35.
- 500 denotes a slide rail when the hopper 1 is drawn out as 11 (it is also shown on the opposite side but not shown).
- the slide rail 500 shown here is, for example, a linear ball sliding bearing, and a greater load resistance can be obtained by mounting vertically as shown in the figure than by mounting horizontally. While avoiding this slide rail.
- a route from the original loading surface D of the hopper 1 to the U-turn inlet is realized and compatible. With such an arrangement, a low height of, for example, 10 O mm can be realized in the entire apparatus.
