Image recording apparatus
View Patent ↗In an image recording apparatus, there are oppositely arranged an image recording section capable of recording an image all over the recording width of a recording medium, and a platen section which holds the recording medium and which conveys the recording medium perpendicularly to a width direction of the recording medium. A platen driving unit can vary a space between the image recording section and the platen section. Positioning pins of a carriage are engaged with slide hooks to set a space between the platen driving unit and the image recording section.
1. An image recording apparatus comprising:
a recording medium conveying section which conveys a recording medium;
an image recording section configured to record an image over an entire recording width of the recording medium;
a space varying section which is movable to be brought into contact with the recording medium conveying section, and which moves the recording medium conveying section to a record position where the image is recorded and a standby position different from the record position; and
an engaging section which engages the recording medium conveying section with the image recording section in an image recording state in which the image is recorded by the image recording section,
wherein the space varying section is not in contact with the recording medium conveying section in the image recording state.
2. The image recording apparatus according to claim 1 , wherein the recording medium conveying section is held only by the image recording section via the engaging section in the image recording state.
3. The image recording apparatus according to claim 2 , wherein the engaging section specifies a distance between the image recording section and the recording medium conveying section to a predetermined value in the image recording state.
4. The image recording apparatus according to claim 2 , wherein:
the engaging section includes a first fit portion which is provided in one of the image recording section and the recording medium conveying section and which projects in a direction in which the image recording section faces the recording medium conveying section, and a second fit portion which is provided in the other of the image recording section and recording medium conveying section where the first fit portion is not provided and which is movable in a direction perpendicular to the direction in which the first fit portion projects; and
the second fit portion is movable to fit to the first fit portion.
5. The image recording apparatus according to claim 4 , wherein the first fit portion and the second fit portion fit to each other and thereby specify a distance between the image recording section and the recording medium conveying section to a predetermined value in the image recording state.
6. The image recording apparatus according to claim 5 , wherein the first fit portion and the second fit portion fit in a plurality of different positions depending on an amount of movement of the second fit portion, and the distance between the image recording section and the recording medium conveying section is changeable.
7. The image recording apparatus according to claim 6 , wherein the amount of movement of the second fit portion is determined by at least a thickness of the recording medium.
8. The image recording apparatus according to claim 1 , wherein:
the image recording section and the recording medium conveying section are disposed opposite to each other;
the space varying section moves the recording medium conveying section up and down while the recording medium conveying section and the image recording section are opposite to each other; and
the recording medium conveying section is suspended from the image recording section via the engaging section in the image recording state.
9. The image recording apparatus according to claim 8 , wherein the engaging section specifies a distance between the image recording section and the recording medium conveying section to a predetermined value in the image recording state.
10. The image recording apparatus according to claim 8 , wherein:
the engaging section includes a first fit portion which is provided in one of the image recording section and the recording medium conveying section and which projects in a direction in which the image recording section faces the recording medium conveying section, and a second fit portion which is provided in the other of the image recording section and the recording medium conveying section where the first fit portion is not provided and which is movable in a direction perpendicular to the direction in which the first fit portion projects; and
the second fit portion is movable to fit to the first fit portion.
11. The image recording apparatus according to claim 10 , wherein the first fit portion and the second fit portion are fit and thereby specify a distance between the image recording section and the recording medium conveying section to a predetermined value in the image recording state.
12. The image recording apparatus according to claim 11 , wherein the first fit portion and the second fit portion fit in a plurality of different positions depending on an amount of movement of the second fit portion, and the distance between the image recording section and the recording medium conveying section is changeable.
13. The image recording apparatus according to claim 12 , wherein the amount of movement of the second fit portion is determined by at least a thickness of the recording medium.
