Abstract

In a recording apparatus, one end section sides of first liquid supply tubes are connected to ink tanks which are provided to be able to be attached and detached from outer sections of a main housing. Other end section sides of second liquid supply tubes, where one end section sides are connected to a liquid ejecting head side which is provided in an inner section of the main housing, are connected to other end section sides of the first liquid supply tubes using connection members. Out of first connection sections which are provided in the connection members on the first liquid supply tubes side and second connection sections which are provided in the connection members on the second liquid supply tubes side, at least the first connection sections are provided so as to be positioned at outer sections of the main housing.

First claim

The invention claimed is:

1. A recording apparatus comprising:
a main housing;
a liquid ejecting head which is provided in an inner section of the main housing and which ejects a liquid with regard to a target;
a liquid container section which is provided on an outer section of the main housing;
a container casing where the liquid container section is contained, the container casing being provided on the outer section of the main housing;
a first liquid supply tube where one end section side is connected to the liquid container section, the first liquid supply tube extending from the liquid container section and extending inside of the container casing;
a second liquid supply tube where one end section side is connected to the liquid ejecting head side, the second liquid supply tube extending from an inside of the main housing to an inside of the container casing; and
a connection member which connects the other end section sides of the first liquid supply tube and the second liquid supply tube,
wherein the connection member is configured by a first connection section which is provided on the first liquid supply tube side and a second connection section which is provided on the second liquid supply tube side, and
at least the first connection section of the connection member is entirely positioned outside of the liquid container section and positioned at an inner section of the container casing which is provided at the outer section of the main housing.

2. The recording apparatus according to claim 1 ,
wherein an opening is formed in the main housing so that at least the first connection section of the connection member is exposed inside the container casing, and the position of the opening is set so that the opening is at a position so as to expose toward the outside of the container casing when a cover for the container casing is removed.

3. The recording apparatus according to claim 2 ,
wherein the liquid container section is configured to be freely attached and detached via a locking section, and
the opening is provided at a location which is different to the locking section.

4. The recording apparatus according to claim 1 ,
wherein sealing members, which seal the first liquid supply tube and the second liquid supply tube when the connection between the other end section sides of the first liquid supply tube and the second liquid supply tube using the first connection section and the second connection section is released, are provided at an end section of the first liquid supply tube on the first connection section side and at an end section of the second liquid supply tube on the second connection section side.

5. The recording apparatus according to claim 1 , further comprising:
a valve mechanism which has a valve body which is able to be displaced between a sealing position for sealing an opening in one of end sections out of an end section of the first liquid supply tube on the first connection section side and an end section of the second liquid supply tube on the second connection section side and an open position for opening the opening in the one end section, and a pressing section which presses the valve body toward the sealing position,
wherein the valve mechanism is configured so that the valve body is held at the open position against pressing force of the pressing section when the first connection section and the second connection section are in a state of being connected and holding of the valve body at the open position is released when the first connection section and the second connection section are separated, and the valve mechanism has a check valve which is provided at the end section which is the opposite of the end section where the opening is sealed using the valve body, and
the check valve is configured so as to permit only flow of liquid from the liquid container section side to the liquid ejecting head side.

6. The recording apparatus according to claim 1 ,
wherein a detecting unit, which detects that the connection between the first connection section and the second connection section is released, is provided in the connection member, and
a control section is provided so as to execute a blocking process for blocking flow of liquid from the liquid container section side to the liquid ejecting head side when releasing of the connection between the first connection section and the second connection section is detected using the detecting unit.

7. The recording apparatus according to claim 1 ,
wherein a detecting unit, which is for detecting that the connection between the first connection section and the second connection section is released, is provided in the second connection section, and
an information transmitting section is provided to carry out notification that releasing of the connection between the first connection section and the second connection section is detected using the detecting unit when the releasing of the connection is detected.

8. The recording apparatus according to claim 1 ,
wherein the first liquid supply tube extends outside from the liquid container section such that the other end section side of the first liquid supply tube is positioned outside of the liquid container section, and
the first connection section is disposed at the other end section side of the first liquid supply tube.

9. The recording apparatus according to claim 1 , further comprising
a liquid container unit including the container casing and a cover detachably attached to the container casing, and
a locking section which is disposed in the container casing and to which the liquid container section is removably locked, wherein
the cover is configured to be attached to and detached from the container casing in a state where the liquid container section is locked to the locking section.

10. A recording apparatus comprising:
a main housing;
a liquid ejecting head which is provided in an inner section of the main housing and which ejects a liquid with regard to a target;
a liquid container section which is provided on an outer section of the main housing;
a container casing where the liquid container section is contained;
a first liquid supply tube where one end section side is connected to the liquid container section;
a second liquid supply tube where one end section side is connected to the liquid ejecting head side; and
a connection member which connects the other end section sides of the first liquid supply tube and the second liquid supply tube,
wherein the connection member is configured by a first connection section which is provided on the first liquid supply tube side and a second connection section which is provided on the second liquid supply tube side,
at least the first connection section of the connection member is entirely positioned outside of the liquid container section and positioned at an inner section of the container casing which is provided at the outer section of the main housing, and
an opening is formed in the main housing so that at least the first connection section of the connection member is exposed inside the container casing, and the position of the opening is set so that the opening is at a position so as to expose toward the outside of the container casing when a cover for the container casing is removed.

11. A recording apparatus comprising:
a main housing;
a liquid ejecting head which is provided in an inner section of the main housing and which ejects a liquid with regard to a target;
a liquid container section which is provided on an outer section of the main housing;
a container casing where the liquid container section is contained;
a first liquid supply tube where one end section s
