Abstract

A printer includes a carriage which includes an ink jet recording head and is movable in a first direction and a second direction that is an opposite direction to the first direction, a gear group which transmits power of a motor to a sheet transporter, a transporter drive motor which transmits power to the gear group, and a carriage drive motor which drives the carriage. At least a portion of the carriage drive motor and at least a portion of the gear group are at the same position as each other in a movement direction (x direction) of the carriage.

First claim

What is claimed is:

1. A recording apparatus comprising:
a carriage which includes a recording head performing a recording on a medium and is movable in a predetermined direction;
a carriage drive motor which drives the carriage;
a transporter which transports the medium;
a transporter drive motor which drives the transporter; and
a power transmission mechanism which transmits power of the transporter drive motor to the transporter,
wherein the carriage drive motor, the transporter drive motor and the power transmission mechanism are disposed near the side wall of the apparatus,
wherein the movement direction of the carriage is the x direction, the transport direction of the medium is the y direction, and the vertical direction is the z direction,
wherein a portion of the carriage drive motor and a portion of the power transmission mechanism are located overlapping in the x direction, and
wherein the carriage drive motor is located between a carriage movement area and the transporter drive motor.

2. The recording apparatus according to claim 1 ,
wherein at least a portion of the power transmission mechanism is located on a bottom side of the carriage drive motor.

3. The recording apparatus according to claim 2 ,
wherein at least a portion of the carriage drive motor and at least a portion of the power transmission mechanism are located at the same position as each other in a vertical direction.

4. The recording apparatus according to claim 3 , further comprising:
a frame which extends in a direction intersecting with the movement direction of the carriage in an end region on one side in a movement region of the carriage,
wherein the power transmission mechanism includes a plurality of gears which are arranged in an extending direction of the frame.

5. The recording apparatus according to claim 1 ,
wherein the portion of the carriage drive motor and the portion of the transporter drive motor are located overlapping in the z direction.

6. The recording apparatus according to claim 5 ,
wherein the portion of the carriage drive motor and the portion of the transporter drive motor are located overlapping in the x direction.

7. The recording apparatus according to claim 6 ,
wherein the portion of the carriage drive motor and the portion of the transporter drive motor are located overlapping in the y direction.

8. The recording apparatus according to claim 7 , further comprising:
a medium feeding section which feeds a medium; and
a housing which accommodates an apparatus main body that includes the carriage, the carriage drive motor, the transporter, the transporter drive motor, the power transmission mechanism, and the medium feeding section,
wherein the medium feeding section includes a medium setting unit which sets a medium, and
the carriage drive motor is arranged between the housing and the medium setting unit.

9. The recording apparatus according to claim 8 ,
wherein the portion of the power transmission mechanism is positioned under the carriage which is moved to an end of a movable region of the carriage.

10. The recording apparatus according to claim 1 , further comprising:
a connection section to which an external power supply source is connected,
wherein the portion of the carriage drive motor and the portion of the connection section are located overlapping in the x direction.

11. The recording apparatus according to claim 1 , further comprising:
the connection section to which the external power supply source is connected,
wherein at least a portion of the carriage drive motor and at least a portion of the connection section are located overlapping in the z direction.

12. The recording apparatus according to claim 1 , further comprising:
the connection section to which the external power supply source is connected,
wherein the portion of the transporter drive motor and the portion of the connection section are located overlapping in the x direction.

13. The recording apparatus according to claim 1 , further comprising:
the connection section to which the external power supply source is connected,
wherein the portion of the transporter drive motor and the portion of the connection section are located overlapping in the y direction.

14. The recording apparatus according to claim 1 , further comprising:
the connection section to which the external power supply source is connected,
wherein the portion of the power transmission mechanism and the portion of the connection section are located overlapping in the x direction.

15. The recording apparatus according to claim 10 ,
wherein the connection section includes an input/output interface.

16. The recording apparatus according to claim 11 ,
wherein the connection section includes the input/output interface.

17. The recording apparatus according to claim 12 ,
wherein the connection section includes the input/output interface.

18. The recording apparatus according to claim 13 ,
wherein the connection section includes the input/output interface.

19. The recording apparatus according to claim 14 ,
wherein the connection section includes the input/output interface.
