The present invention relates to a liquid container that contains a liquid to be supplied to a liquid consuming device, and a terminal unit provided in the liquid container.

2. Description of the Related Art Conventionally, there is a liquid consuming apparatus that includes a liquid ejecting unit that ejects a liquid such as ink, and an ink container that supplies a liquid such as ink is detachably mounted. In this type of removable ink container, a substrate for storing information such as ink stored therein is mounted. The substrate (circuit board) includes a terminal portion that is electrically connected to a terminal portion on the liquid consuming device side in a state where the ink container is mounted on the liquid consuming device. In order to securely connect the terminal portion on the substrate mounted on the ink container and the terminal portion on the liquid consumption device side, a positioning portion is provided on one of the ink container and the liquid consumption device, and the positioning portion is positioned on the other side. Some have a regulation section to regulate. Patent Document 1
Discloses an ink container and a liquid consuming device of this type.

In Patent Document 1, positioning protrusions are provided on both sides of the terminal portion on the liquid consuming device side, and grooves are provided on both sides of the substrate mounted on the ink container. When the ink container is attached to the liquid consuming device, the positioning protrusion starts to be inserted into the groove before the terminal portion on the substrate and the terminal portion on the liquid consuming device side are connected. The positioning protrusion is guided by the groove portion, whereby the ink container is positioned with respect to the liquid consuming device, and the terminal portion on the substrate side is positioned with respect to the terminal portion on the liquid consuming device side. As a result, the terminal part on the substrate and the terminal part on the liquid consuming apparatus side can be brought into contact with each other in a state where the mounting of the ink container to the liquid consuming apparatus is completed.

International Publication No. 2013/105504

FIG. 11 is a perspective view showing a positioning structure of a terminal portion using positioning protrusions and grooves according to a conventional example. As shown in FIG. 11, the terminal part 202 is provided in the liquid consuming device of Patent Document 1, and a positioning protrusion 201 is fixed or integrally formed on a holding member that holds the terminal part 202. On the other hand, a substrate 213 including a terminal portion 212 is mounted on the ink container, and a groove portion 211 is formed in a portion that holds the substrate 213. In such a positioning structure, the contact point Q at which the terminal portion 212 on the substrate 213 side and the terminal portion 202 on the liquid consumption device side are in contact with each other.
1 is an action point at which a reaction force F1 corresponding to the terminal contact pressure acts.

Here, the terminal unit on the liquid consuming device side including the terminal unit 202 may be in a state of rattling with respect to the liquid consuming device or the liquid container mounting portion. In particular, when the terminal unit on the liquid consuming device side rattles in the direction in which the terminal contact pressure decreases with respect to the terminal unit that is the connection partner (the terminal unit on which the ink container side substrate 213 is mounted), When the terminal unit 202 receives the reaction force F1 at the contact point Q1, the reaction force F1 moves the terminal unit on the liquid consuming device side. As a result, the terminal unit 202 moves away from the terminal unit 212, and the terminal contact pressure decreases. Resulting in. Therefore, there is a possibility that the terminal portion 212 and the terminal portion 202 cannot be stably contacted.

More specifically, as shown in FIG. 11, when the terminal unit 202 on the liquid consuming device side receives the reaction force F1 at the contact point Q1, the terminal unit 202 moves in the direction of the reaction force F1, and as a result, the terminal unit The positioning protrusion 201 tries to move in the direction of the reaction force F <b> 1 together with 202. However,
Since the positioning protrusion 201 is fitted in the groove 211, the rotational moment that rotates the positioning protrusion 201 in the direction of the reaction force F1 with the contact point Q2 where the tip of the positioning protrusion 201 contacts the inner wall surface of the groove 211 as a fulcrum. M1 acts. And since the opening edge of the groove part 211 contacts the base end part of the positioning protrusion 201 at the contact point Q3, the positioning protrusion 201 is restricted from rotating in the direction of the rotational moment M1.

Here, as shown in FIG. 11, in the structure of Patent Document 1, the contact point Q1, which is a force point at which the reaction force F1 works, is a contact point, which is an action point at which the positioning projection 201 is pressed against the opening edge of the groove 211 by the reaction force F1. The distance from the contact point Q2 which is a fulcrum is larger than the point Q3. In such a positional relationship, when there is rattling (that is, a gap between the positioning projection 201 and the inner surface of the groove 211) at the contact point Q3, which is the point of action, it occurs at the contact point Q1, which is the force point. The shakiness between the terminals is larger. Therefore, the terminal contact pressure cannot be secured,
There is a possibility that the terminal portion 212 and the terminal portion 202 cannot be stably contacted.

In order to avoid such an inconvenience, the rattling between the members at the contact point Q3, which is the action point, may be reduced. However, for this purpose, since the gap between the positioning projection 201 and the groove portion 211 must be reduced, it becomes difficult to insert the positioning projection 201 into the groove portion 211.

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a liquid consuming device for positioning a terminal portion on a substrate provided in a liquid container such as an ink container and a terminal portion on the liquid consuming device side. Terminal unit capable of suppressing a decrease in terminal contact pressure due to rattling between a positioning portion provided on the terminal unit on the side and a regulating portion provided on the terminal unit on the liquid container side, and the terminal unit It is in proposing the liquid container provided with.

In order to solve the above problems, the present invention provides a device-side terminal unit having a device-side terminal portion and a positioning portion, and the device-side terminal unit is movable in the pressure direction of contact pressure received by the device-side terminal portion. A terminal unit provided in a liquid container that can be attached to the liquid consuming device, wherein the device side is the direction in which the liquid container is attached to the liquid consuming device. A terminal portion that contacts the terminal portion in the mounting direction; and a restricting portion that restricts a position of the positioning portion in a direction crossing the mounting direction.
It has a contact for applying a reaction force in contact with the device side terminal portion, and the restricting portion rotates by the reaction force with the first contact portion in contact with the positioning portion and the first contact portion as a fulcrum. The positioning portion has a second contact portion that is in contact with the direction opposite to the rotation direction due to the reaction force, and the distance between the second contact portion and the first contact portion is the first contact portion and the first contact portion. It is more than the distance with a contact part.

According to the present invention, in the structure in which both terminal units are positioned by the positioning unit provided in the device-side terminal unit of the liquid consuming device and the restriction unit of the terminal unit provided in the liquid container, the device-side terminal unit and the liquid container side The contact point, which is the point where the reaction force works with the terminal part, the first contact part that becomes the fulcrum when the positioning part rotates by this reaction force, and the positioning part that rotates by the reaction force press against the regulating part The positional relationship with the second contact portion that is the acting point (that is, the point where the restricting portion contacts the positioning protrusion in the direction opposite to the reaction force) Is also defined to be smaller. Accordingly, a decrease in terminal contact pressure caused by rattling between the regulating part of the liquid container and the positioning part on the apparatus side, which is provided for positioning the terminal part on the liquid container side and the terminal part on the apparatus side. Can be suppressed. Therefore, poor contact between terminals can be prevented.

In the present invention, when the positioning portion is a positioning protrusion extending in the mounting direction, the restricting portion is a groove or a hole extending in the mounting direction, and the first contact portion is the groove or the hole. It is desirable that the inner surface of the hole is in contact with the distal end side of the positioning protrusion, and the second contact portion is an edge on the front side in the mounting direction in the groove or the hole. If it does in this way, the inner surface of the groove | channel or hole which contacts the front-end | tip part of a positioning protrusion will become a fulcrum, and the edge of a groove | channel or a hole will become an action point. Therefore, by extending the protrusion and groove or hole so that the action point is farther from the fulcrum than the force point, the terminal contact pressure can be reduced even if there is rattling between the positioning groove or hole and protrusion. Can be suppressed.

In order to solve the above-mentioned problems, the present invention moves a device-side terminal unit having a device-side terminal portion and a positioning portion, and the device-side terminal unit in the pressure direction of contact pressure received by the device-side terminal portion. A liquid container that can be mounted on a liquid consuming device, and a liquid supply that supplies the liquid from the liquid container to the liquid consuming device. And a storage unit holding unit that holds the liquid storage unit, wherein the storage unit holding unit includes the terminal unit according to claim 1, wherein the storage unit holding unit is used as the liquid consuming device. When the device side terminal portion is moved toward the mounting direction, the position of the positioning portion is restricted by the restricting portion before the device-side terminal portion and the terminal portion are connected.

As described above, in the liquid container of the present invention, when the container holding part is moved in the mounting direction, the positioning by the positioning part and the regulating part is performed before the terminal parts are connected to each other. Therefore, contact failure between terminals can be prevented when the liquid container is mounted.

In the present invention, the storage portion holding portion includes a main body portion that holds the liquid storage portion, the terminal unit includes a protrusion portion that protrudes from the main body portion in the mounting direction, and the protrusion portion includes:
It is desirable that an inclined surface inclined with respect to the mounting direction is provided, and the terminal portion is disposed on the inclined surface. Thus, by arranging the terminal portion on the inclined surface, the possibility of poor contact between the terminals can be reduced. Further, since the terminal portions are in sliding contact with each other at the time of connection, foreign matters attached to the terminal portions can be removed.

In this invention, the said accommodating part holding | maintenance part has several engaging parts provided with the several engaging part provided in the storage container which accommodates the said liquid container, At least several said engaged parts It is desirable that one of the joint portions is engaged with the engagement portion in a movable state. Thus, when there are a plurality of engaging portions and engaged portions, accurate positioning is possible. Further, since there is a backlash between the engaging portion and the engaged portion, it is easy to engage the engaged portion and the engaging portion. Therefore, positioning can be performed reliably and contact failure between terminals can be prevented more reliably. Further, liquid leakage due to poor connection of the liquid supply unit to the liquid consuming device can be suppressed.

The distance traveled in the direction away from the terminal portion 105) is the distance traveled by the printer-side terminal unit 120 at the second contact point P3 (the dimension by which the positioning projections 128A and 128B can rattle at the opening edges of the groove portions 106A and 106B). Can be the same or smaller. Therefore, although the printer side terminal unit 120 is supported by the connector housing 61 so as to be movable in the direction in which the terminal contact pressure decreases, the decrease in the terminal contact pressure can be reduced.
