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, the recording head configured to perform a recording on a medium, wherein the carriage is movable in a carriage movement direction;
a carriage drive motor which drives the carriage;
a transporter which transports the medium in a transport direction;
a transporter drive motor which drives the transporter;
a power transmission mechanism which transmits power of the transporter drive motor to the transporter; and
a housing which accommodates an apparatus main body, wherein the main body includes the carriage, the carriage drive motor, the transporter, the transporter drive motor, and the power transmission mechanism,
wherein the carriage drive motor, the transporter drive motor and the power transmission mechanism are disposed near a same side wall of the housing,
wherein the transporter drive motor is located at a rear side corner that is opposite a medium discharge port of the housing, and
wherein a portion of the carriage drive motor and a portion of the transporter drive motor are positioned so as to overlap in the vertical direction.

2. The recording apparatus according to claim 1 , wherein the portion of the carriage drive motor and the portion of the transporter drive motor are positioned so as to overlap in the carriage movement direction.

3. The recording apparatus according to claim 1 , wherein the portion of the carriage drive motor and the portion of the transporter drive motor are positioned so as to overlap in the medium transport direction.

4. The recording apparatus according to claim 1 , further comprising a medium feeding section which feeds a medium,
wherein the medium feeding section includes a medium setting unit which sets a medium, and
the transporter drive motor is arranged between the housing and the medium setting unit.

5. The recording apparatus according to claim 1 , 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.

6. The recording apparatus according to claim 1 , further comprising:
a 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 carriage movement direction.

7. The recording apparatus according to claim 1 , further comprising
a 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 medium transport direction.

8. A recording apparatus comprising:
a carriage which includes a recording head, the recording head configured to perform a recording on a medium, wherein the carriage is movable in a carriage movement direction;
a carriage drive motor which drives the carriage;
a transporter which transports the medium in a medium transport direction;
a transporter drive motor which drives the transporter; and
a power transmission mechanism which transmits power of the transporter drive motor to the transporter,
a housing which accommodates an apparatus main body, wherein the main body includes the carriage, the carriage drive motor, the transporter, the transporter drive motor, and the power transmission mechanism,
wherein the carriage drive motor, the transporter drive motor and the power transmission mechanism are disposed near a same side wall of the housing, and
wherein a portion of the carriage drive motor and a portion of the transporter drive motor are positioned so as to overlap in the medium transport direction and in the carriage movement direction,
wherein at least a portion of the power transmission mechanism is positioned below the carriage when the carriage is positioned near the side wall.
