Abstract
There is provided a printing apparatus including: a head unit including two first heads and a second head; a support unit arranged to face the head unit and has a support surface; and a sensor arranged between a first virtual line extending in a conveyance direction so as to pass an end of a nozzle group area, of one of the two first heads, defined on a side of other of the two first heads and a second virtual line extending in the conveyance direction so as to pass an end of a nozzle group area, of the other of the two heads, defined on a side of the one of the two first heads, and arranged, in the conveyance direction, upstream of a nozzle group of the second head, the sensor including a projecting member which projects toward the supporting surface with respect to a nozzle surface.
Claims18
A printing apparatus comprising:
- a head unit including:
- a first head which has a nozzle surface having a nozzle group area in which a nozzle group configured to perform a printing on a medium is formed,
- a second head which has a nozzle group configured to perform the printing on the medium, and which is arranged downstream of the first head in a conveyance direction in which the medium is conveyed,
- a support unit which is arranged to face the head unit, and which has a support surface configured to support the medium;
- and
- a sensor which is arranged upstream of the nozzle group of the second head such that the sensor and the nozzle group of the second head overlap as seen in the conveyance direction, the sensor being arranged in a crossing direction crossing the conveyance direction at a position different from the nozzle group area of the first head, the sensor including a projecting member which projects toward the supporting surface with respect to the nozzle surface, wherein
- the first head includes two heads each has the nozzle surface having the nozzle group area in which the nozzle group configured to perform the printing on the medium is formed, the two heads being arranged with a gap in the crossing direction;
- and
- the sensor is arranged between a first virtual line extending in the conveyance direction so as to pass an end of the nozzle group area, of one of the two heads of the first head, defined on a side of other of the two heads of the first head and a second virtual line extending in the conveyance direction so as to pass an end of the nozzle group area, of the other of the two heads of the first head, defined on a side of the one of the two heads of the first head.
A printing apparatus comprising:
- a head unit including:
- a first head which has a nozzle surface having a nozzle group area in which a nozzle group configured to perform a printing on a medium is formed,
- a second head which has a nozzle group configured to perform the printing on the medium, and which is arranged downstream of the first head in a conveyance direction in which the medium is conveyed,
- a support unit which is arranged to face the head unit, and which has a support surface configured to support the medium;
- a sensor which is arranged upstream of the nozzle group of the second head such that the sensor and the nozzle group of the second head overlap as seen in the conveyance direction, the sensor being arranged in a crossing direction crossing the conveyance direction at a position different from the nozzle group area of the first head, the sensor including a projecting member which projects toward the supporting surface with respect to the nozzle surface;
- and
- a guide mechanism which is arranged, in the conveyance direction, upstream of the head unit, and which is configured to perform positioning of the medium in a width direction with two guide plates arranged to face each other, wherein
- the sensor is arranged between a virtual line extending in the conveyance direction along a surface of one of the two guide plates without passing the first head, and an end of the nozzle group area of the first head defined on a side of the virtual line.
