Claims
- 1. A medium transporting apparatus comprising:
- a drawer which is slidable between open and closed positions with respect to said apparatus and includes a hopper part on which a medium to be transported through said apparatus is placed;
- first rollers, disposed on said drawer, transporting the medium placed on said hopper part therefrom;
- second rollers, disposed at a location within said apparatus displaced from said first rollers, further transporting the medium transported by said first rollers;
- a driving unit, disposed on said drawer, producing driving power for selectively driving said first and second rollers and transporting a medium from the hopper part and through said apparatus; and
- a transmitting unit selectively transmitting the driving power of said driving unit to at least said second rollers when said drawer is in the closed position.
- 2. The medium transporting apparatus as claimed in claim 1, wherein said transmitting unit transmits the driving power of said driving unit to said first and said second rollers when said drawer is in the closed position.
- 3. The medium transporting apparatus as claimed in claim 2, wherein said driving unit comprises a single motor.
- 4. The medium transporting apparatus as claimed in claim 1, wherein said transmitting unit transmits the driving power of said driving unit to said first rollers when said drawer is in the open position.
- 5. The medium transporting apparatus as claimed in claim 1, wherein said transmitting unit comprises a coupling mechanism which couples said driving unit and said first and second rollers.
- 6. The medium transporting apparatus as claimed in claim 5, wherein said coupling mechanism is responsive to movement of said drawer to the closed position to couple the driving unit to the second rollers.
- 7. The medium transporting apparatus as claimed in claim 6, further comprising:
- a case;
- the transmitting unit being mounted on and movable with the drawer between the open and closed position of the drawer, relatively to the case;
- the coupling mechanism including a first coupling element mounted on the drawer and a second coupling element mounted on the case, the first coupling element being displaced from the second coupling element in the open position of the drawer and engaging the second element in the closed position of the drawer, the driving unit driving the second roller when the first and second coupling elements are engaged.
- 8. The medium transporting apparatus as claimed in claim 6, further comprising:
- a case;
- the transmitting unit being mounted on and movable with the drawer between the opened and closed position of the drawer, relatively to the case;
- the coupling mechanism including a first coupling element mounted on the drawer and a second coupling element mounted on the case, the first coupling element being displaced from the second coupling element in the opened position of the drawer and engaging the second element in the closed position of the drawer, the driving unit driving the second roller when the first and second coupling elements are engaged.
- 9. The medium transporting apparatus as claimed in claim 1, wherein said transmitting unit comprises an electronic coupler electronically activated for coupling said driving unit and said first and second rollers.
- 10. The medium transporting apparatus as claimed in claim 1, wherein said first rollers are disposed at an edge portion of said drawer, said edge portion being located on a most downstream side of said drawer with respect to a direction in which the medium, placed on said hopper part, is transported.
- 11. The medium transporting apparatus as claimed in claim 1, further comprising a stacker disposed beneath the hopper in the closed position of the drawer, the second rollers transporting the medium, in the closed position of the drawer, through the apparatus and into the stacker.
- 12. A medium transporting apparatus comprising:
- a drawer which is slidable between open and closed positions with respect to said apparatus and includes a hopper part on which a medium to be transported through said apparatus is placed;
- first rollers, disposed on said drawer, transporting the medium placed on said hopper part therefrom;
- second rollers, disposed at a location within said apparatus displaced from said first rollers, further transporting the medium transported by said first rollers;
- a driving unit, disposed on said drawer, producing driving power for selectively driving said first and second rollers for transporting a medium from the hopper part and through said apparatus; and
- transmitting means selectively transmitting the driving power of said driving unit to at least said second rollers when said drawer is in the closed position.
- 13. The medium transporting apparatus as claimed in claim 12, wherein said transmitting means transmits the driving power of said driving unit to said first and second rollers when said drawer is in the closed position.
- 14. The medium transporting apparatus as claimed in claim 13, wherein said driving unit comprises a single motor.
- 15. The medium transporting apparatus as claimed in claim 12, wherein said transmitting means transmits the driving power of said driving unit to said first rollers when said drawer is in the open position.
- 16. The medium transporting apparatus as claimed in claim 12, wherein said transmitting means comprises a coupling mechanism which couples said driving unit and said first and second rollers.
- 17. The medium transporting apparatus as claimed in claim 12, wherein said transmitting means comprises an electronic coupler electronically activated for coupling said driving unit and said first and second rollers.
- 18. The medium transporting apparatus as claimed in claim 12, wherein said first rollers are disposed at an edge portion of said drawer, said edge portion being located on a most downstream side of said drawer with respect to a direction in which the medium, placed on said hopper part, is transported.
- 19. The medium transporting apparatus as claimed in claim 12, further comprising a stacker disposed beneath the hopper in the closed position of the drawer, the second rollers transporting the medium, in the closed position of the drawer, through the apparatus and into the stacker.
- 20. The medium transporting apparatus as claimed in claim 19, wherein said coupling mechanism is responsive to movement of said drawer to the closed position to couple the driving unit to the second rollers.
