摘要： Mechanism for producing vacuum pressure and air flow for drawing recording paper of various widths to the platen surface of a printer enables such pressure and air flow to be held in a suitable range without adjusting the suction. A first suction area of specified width is disposed width-wise in the middle of the platen surface that opposes the inkjet head of the printer, and second suction areas are disposed on the left and right sides of the first suction area, the front edge of which is offset from the front edge of the second suction areas. The first suction area is divided to form first chambers, each having a first suction hole that communicates with a vacuum channel. The second suction areas are segmented to form second chambers, some, but not all, of which are formed with second suction holes that are spaced from the first suction holes.

摘要： A printer has an exhaust path that rectifies the exhaust flow of a centrifugal fan for producing air flow through a vacuum platen. Exhaust from a centrifugal fan 30 tends to flow in the direction of rotation A of the blades due to inertia even after being discharged from the exhaust opening 39. The exhaust thus produces a curving exhaust current C. An exhaust duct 32 connected to the exhaust opening 39 of the centrifugal fan 30 therefore curves in the direction of rotation A of the blades so as to not impede the flow of the exhaust current C. As a result, turbulence inside the exhaust duct 32 is suppressed, and the exhaust current C is rectified. The exhaust from the centrifugal fan 30 can therefore flow smoothly, and a loss of exhaust flow can be suppressed. In addition, noise caused by the exhaust current C hitting the inside wall of the exhaust duct 32 can be suppressed.
摘要翻译：打印机具有排气路径，其对离心式风扇的排气进行整流，以产生通过真空压板的气流。离心式风扇30的排气即使在从排气口39排出之后也因为惯性而在叶片的旋转方向A上流动。因此排气产生弯曲排气流C.连接到排气口的排气管32 因此离心式风扇30因此在叶片的旋转方向A上弯曲，从而不会妨碍排气流C的流动。结果，排气管道32内的湍流被抑制，排气电流C被整流。因此，离心风扇30的排气能够平稳地流动，能够抑制排气流的损失。此外，可以抑制由排气管C的内壁撞击的排气流C引起的噪声。

摘要： The invention provides, as an aspect thereof, an inkjet printer that connects a vacuum fan on the printer case side and a vacuum platen on the cover side through a short vacuum path. The platen moves in conjunction with the cover of the roll paper compartment. The platen is a vacuum platen having vacuum regions, suction holes and a platen-side air path on the platen side, and a vacuum fan and a vacuum duct that connects the vacuum fan to the suction unit of the platen on the printer case side. The vacuum duct is disconnected from the suction unit of the platen when the platen moves in conjunction with the cover, and the length of the vacuum duct can therefore be short, corresponding to the distance between the intake opening of the vacuum fan and the suction unit of the platen when the cover is closed.

摘要： A liquid container including a liquid chamber formed to have a flexible member as its one part enables highly accurate detection of the remaining volume of a liquid contained in the liquid chamber. An ink cartridge 100 as one embodiment of the liquid container has an ink chamber 101 configured to contain ink, formed to have a film 120 as its one part and subjected to reduction of inner capacity caused by deformation of the film 120 associated with a decrease in internal pressure of the ink chamber 101. The ink cartridge 100 also has an ink supply hole 130 configured to feed the ink out of the liquid chamber, a conical spring 155 configured to maintain negative pressure in the ink chamber 101, and a prism 150 involved in detection of the remaining volume of the ink in the ink chamber 101. The prism 150 is located in an unaffected area inside the ink cartridge 100, which is not subjected to a capacity change caused by deformation of the film 120.

摘要： A membrane valve having a membrane portion is used. The membrane valve can be formed using an elastomer. Also, the membrane valve can include N (N is an integer of 2 or greater) engaging portions that engage with the membrane support portion. Also, the membrane portion can also be affixed at a position closer to the first seal surface than the second seal surface in the seal portion. Here, the contact area of the first seal surface and the first member can be larger than the contact surface of the second seal surface and the second member. Also, in a first case where the end of the projecting portion is faced to a first plane and the membrane valve placed on the first plane, the end of the first support portion contacts the first plane and supports the membrane valve, and the end of the projecting portion can contact the first plane in a state with the membrane portion not deformed. Also, the projecting portion inserted inside the end of the coil spring can be arranged at the center axis side separated from the range of the position in which the projecting portion can contact the end of the coil spring by motion of the coil spring within the concave portion in the direction perpendicular to the center axis of the coil spring.

摘要： Mechanism for producing vacuum pressure and air flow for drawing recording paper of various widths to the platen surface of a printer enables such pressure and air flow to be held in a suitable range without adjusting the suction. A first suction area with the same width as the minimum width of the recording paper is disposed width-wise in the middle of the platen surface that opposes the inkjet head of the printer, and second suction areas are disposed on the left and right sides of the first suction area. The first suction area is divided into a grid by intersecting ribs to form first chambers, each having a first suction hole formed in a bottom thereof that communicates with a vacuum channel. The second suction areas are also segmented to form second chambers. Second suction holes are selectively formed in some, but not all, of the second chambers and are appropriately spaced from the first suction holes. The front edge of the first suction area is offset slightly from the front edge of the second suction areas.
