Printing apparatus and method of controlling printing apparatus
A printing apparatus includes a printing head configured to eject photocurable ink onto a medium, an irradiation portion configured to perform light irradiation of the medium, a mounting portion mounted with the irradiation portion and the printing head in the order from the irradiation portion to the printing head along a first direction, and a driving portion configured to move the mounting portion between a standby position where the printing head stands by and a stop position in the first direction with respect to the standby position. The stop position is a position where the irradiation portion faces the medium.
1 . A printing apparatus comprising:
a printing head configured to eject photocurable ink onto a medium;
a first irradiation portion configured to perform light irradiation of the medium;
a mounting portion mounted with the first irradiation portion and the printing head in order from the first irradiation portion to the printing head along a first direction; and
a driving portion configured to move the mounting portion between a standby position where the printing head stands by and a stop position in the first direction with respect to the standby position;
a support portion that supports the medium; and
a guide shaft along the first direction that guides the mounting portion from the standby position to the stop position, wherein
the stop position is a position where the first irradiation portion faces the medium and the printing head does not face the medium,
a length of the portion of the guide shaft extending beyond the support portion in the first direction is shorter than a length of the mounting portion in the first direction, and longer than a length of the printing head in the first direction, and
an edge of the first irradiation portion on a print head side and an edge of the medium are placed in same position in the first direction when the mounting portion is in the stop position.
2 . The printing apparatus according to claim 1 , further comprising a control portion configured to control the driving portion and the first irradiation portion.
3 . The printing apparatus according to claim 2 , wherein
the control portion causes the first irradiation portion to stop the light irradiation before the mounting portion stops at the stop position.
4 . The printing apparatus according to claim 2 , wherein
the control portion causes the first irradiation portion to reduce a light amount of the light irradiation before the mounting portion stops at the stop position.
5 . The printing apparatus according to claim 2 , further comprising
a second irradiation portion mounted to the mounting portion and configured to perform the light irradiation, wherein
the second irradiation portion is mounted at a position in the first direction of the printing head.
6 . The printing apparatus according to claim 5 , wherein
the control portion:
controls the driving portion to move the mounting portion stopped at the stop position in a second direction being a reverse direction of the first direction and
after moving the mounting portion to a second stop position where the second irradiation portion faces the medium and the printing head does not face the medium, moves the mounting portion from the second stop position in the first direction.
7 . The printing apparatus according to claim 6 , wherein
an edge of the second irradiation portion on a print head side and an edge of the medium are placed in same position in the first direction when the mounting portion is in the second stop position.
8 . The printing apparatus according to claim 1 , wherein the printing head ejects a plurality of types of the photocurable ink onto the medium and the plurality of types of photocurable ink include clear ink.
9 . The printing apparatus according to claim 1 , wherein
a length of the guide shaft beyond the support portion in the second direction is shorter than a length of the mounting portion in the second direction.
10 . The printing apparatus according to claim 1 , wherein the length of the portion of the guide shaft extending beyond the support portion in the first direction is longer than a sum of a length of the printing head and a length of the first irradiation portion in the first direction.
11 . A method of controlling a printing apparatus, the printing apparatus including:
a support portion that supports a medium;
a mounting portion mounted with an irradiation portion and a printing head in order from the irradiation portion to the printing head along a first direction; and
a guide shaft along the first direction that guide the mounting portion from a standby position to a stop position,
wherein the printing apparatus being configured to eject photocurable ink onto the medium,
a length of the guide shaft beyond the support portion in the first direction is shorter than a length of the mounting portion in the first direction, and longer than a length of the printing head in the first direction,
the method comprising:
moving the mounting portion from the standby position in the first direction; and
passing the mounting portion above the medium and stopping the mounting portion at the stop position where the irradiation portion mounted to the mounting portion faces the medium,
wherein an edge of the irradiation portion on a print head side and an edge of the medium are placed in same position in the first direction when the mounting portion is in the stop position.
