In the compressor, a movable body includes a rear wall, a circumferential wall, and a coupling mechanism. The coupling mechanism includes a first arm provided with a first pulling point and a second arm provided with a second pulling point. In the compressor, when the inclination angle of a swash plate is increased, the movable body pulls the swash plate via the first and second arms. At this time, in the compressor, pulling force can be applied at two points, i.e., at the first pulling point and the second pulling point. Consequently, in the compressor, even when the size of the rear wall and the circumferential wall is increased, the rigidity of the first and second arms can be made lower. | 02-04-2016 |

Accordingly, there is a reduction in the force, which has a component in a direction orthogonal to the direction of movement of the movable body, acting on a coupling section of the movable body via a third pin from the swash plate. As a result, when the inclination of the swash plate is changed, unwanted tilting of the movable body relative to the direction of movement is suppressed. | 02-18-2016 |

When viewed from a direction that is perpendicular to the direction in which the rotational axis of the rotary shaft extends and perpendicular to a first direction, the guide surface is configured such that a perpendicular line or a normal line to the guide surface intersects with the rotational axis of the rotary shaft in a zone surrounded by the sliding portion. | 02-18-2016 |
20160069334 | VARIABLE DISPLACEMENT SWASH PLATE TYPE COMPRESSOR - Provided is a compressor, in which the inclination angle of a swash plate is changed by an actuator, ensuring stability on a product-by-product basis while realizing reduction in size. In the compressor, when pressure in a control pressure chamber increases, a movable body moves toward a flange. At this time, the movable body pulls the opposite end side of a swash plate rearward in a swash plate chamber via first and second pulling arms. A link mechanism permits increase of the inclination angle of the swash plate until reaching a maximum value. When the pressure in the control pressure chamber reaches a required control pressure, a rear wall of the movable body which has moved rearward in the swash plate chamber abuts a front face of the flange. This makes it possible in this compressor to restrict the maximum value of the inclination angle of the swash plate. | 03-10-2016 |

The recording head is located adjacent to the first frame when the second frame is in the first position. The recording head is further apart from the first frame when the second frame is in the second position than when the second frame is in the first position. The recording head opposes the supporting portion when the second frame is at the first position. | 02-26-2015 |
20150174908 | RECORDING APPARATUS HAVING LIQUID SUPPLY SYSTEM - In a recording apparatus, a first casing holds a supporting portion. A second casing holds a recording head and a first tank. The second casing is connected to the first casing so as to be rotatable relative to the first casing about a prescribed axis, the second casing being configured to move between a first position and a second position by rotating relative to the first casing, the recording head being located adjacent to the first casing when the second casing is in the first position, the recording head being further apart from the first casing when the second casing is in the second position than when the second casing is in the first position. The recording head opposes the supporting portion when the second casing is in the first position. The second casing is provided with a second tank mounting portion and a liquid transferring portion. | 06-25-2015 |
20150183243 | Recording Apparatus - A recording apparatus includes: recording modules; a storage; a receiver; a first path extending from the storage to the plurality of recording modules; a second path extending from the recording modules to the receiver; and third paths extending between the first path and the second path via first connection positions and second connection positions. The second path has one end connected to the receiver and the other end connected to a portion of the first path which is located upstream of the first connection positions. When the recording medium having passed through the first path once is conveyed to the first path again via the second path, the conveyor conveys the recording medium in a state in which a first surface and a second surface of the recording medium are reversed when compared with a stain which the recording medium passes through the first path in preceding conveyance. | 07-02-2015 |
20150183244 | Recording Apparatus - A recording apparatus includes: first and second recording modules; a storage accommodating a recording medium; a first path extending from the storage to the first recording module; a second path extending from the storage to the second recording module and including a first shared portion shared with the first path; a first roller pair disposed downstream of a first branch position on the first path; and a movement causing member for moving two rollers of the first roller pair to a contact position or a separated position. A controller is configured to: determine whether a leading edge of the recording medium has reached an individual conveyor of the first recording module; when the leading edge has reached the individual conveyor, move the two rollers to the separated position; and supply a recording medium from the storage to the second recording module. | 07-02-2015 |
20150183245 | Recording Apparatus - In a recording apparatus, a first path and a module path of a first recording module for conveying and recording of a recording medium are formed such that a distance between the most downstream ejection opening and a joining position of the first path and a second path is less than a length of a recording medium. The controller executes: a first determination processing for determining whether there is a recording medium which should be conveyed through a join determination position before the recording medium having been supplied to the first recording module; and a wait processing for causing the recording medium having been supplied to the first recording module to wait in a state in which its leading edge is located upstream of the most upstream shared conveyor on the first path, when the controller determines that there is a recording medium. | 07-02-2015 |
20150183602 | Recording Apparatus - A recording apparatus includes: first and second recording modules; a storage accommodating a recording medium; a first path extending from the storage to the first recording module; a second path extending from the storage to the second recording module and including a first shared portion shared with the first path; a first roller pair disposed downstream of a branch position on the first path; and a second roller pair disposed on the first shared portion. The controller is configured to: determine whether a trailing edge of the recording medium on which recording is being performed by the first recording module is located downstream of the first roller pair on the first path; and when the trailing edge is located downstream of the first roller pair on the first path, cause the second roller pair to supply a recording medium from the storage to the second recording module. | 07-02-2015 |
20150183603 | Recording Apparatus - A recording apparatus includes: first and second recording modules; a storage accommodating a recording medium; a first path extending from the storage to the first recording module; and a second path extending from the storage to the second recording module and including a first shared portion shared with the first path. The controller is configured to: determine whether a trailing edge of the recording medium on which recording is being performed by the first recording module is located downstream of the first branch position on the first path; and when the trailing edge of the recording medium is located downstream of the first branch position on the first path, cause a recording medium to be supplied from the storage to the second recording module along the second path via the first shared portion and the first branch position. | 07-02-2015 |
