Abstract

There is provided a printer including first to fourth head chips, and first and second rollers. The first to fourth head chips are arranged at intervals in a second direction orthogonal to a first direction. A nozzle, of nozzles arranged in a second head chip N and used for printing, which is positioned closest to the one side in the second direction is referred to as a nozzle A. A nozzle, of nozzles arranged in a fourth head chip N and used for printing, which is positioned closest to the one side in the second direction is referred to as a nozzle B. The nozzle A is arranged closer to the one side in the second direction than the nozzle B and the first roller is arranged closer to the other side in the second direction than the second roller.

Dependent claims

A printer configured to perform printing on a recording medium, comprising:

first head chips corresponding to a first ink and arrayed at intervals in a second direction orthogonal to a first direction in which the recording medium is conveyed;
second head chips corresponding to the first ink and arrayed at intervals in the second direction at positions which are different from arrangement positions of the first head chips in the second direction and are adjacent to arrangement positions of the first head chips in the first direction;
third head chips corresponding to a second ink and arrayed at intervals in the second direction at positions respectively corresponding to the arrangement positions of the first head chips in the second direction;
fourth head chips corresponding to the second ink and arrayed at intervals in the second direction at positions which respectively correspond to arrangement positions of the second head chips in the second direction and are adjacent to arrangement positions of the third head chips in the first direction;
a first roller arranged to face one of the first head chips in the first direction on one side of a second head chip N in the second direction, the second head chip N being a N-th second head chip of the second head chips counted from the one side in the second direction;
and
a second roller arranged to face one of the third head chips in the first direction on one side of a fourth head chip N in the second direction, the fourth head chip N being an N-th fourth head chip of the fourth head chips counted from the one side in the second direction,
wherein, when the head chip is assumed that a nozzle, of nozzles arranged in the second head chip N and used for printing, which is positioned closest to the one side in the second direction is referred to as a nozzle A and that a nozzle, of nozzles arranged in the fourth head chip N and used for printing, which is positioned closest to the one side in the second direction is referred to as a nozzle B, the nozzle A is arranged closer to the one side in the second direction than the nozzle B and the first roller is arranged closer to the other side in the second direction than the second roller.
