DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink reservoir temporarily stored, a method for laminating and fixing a sheet bundle comprising a plurality of sheets used therein, and an applicator and an ink jet using the same. It relates to a recording device.

[0002]

2. Description of the Related Art In general, a writing instrument is constructed so that the amount of ink transferred from an ink tank to a pen tip is always an appropriate amount, and is provided with a reservoir for retaining overflowing ink. is there. For example, fountain pens, small tube-type writing instruments, felt-tip pens, water-based ball pens, makeup tools and the like are used in many writing instruments that incorporate raw ink.

[0003] This storage body is generally called a collector, a bellows or a flow control body (hereinafter, this storage body is called a "collector"). This collector is usually manufactured as an integral molded product by injection molding using a synthetic resin.
Japanese Patent Application Laid-Open No. 10-58886 (hereinafter, referred to as a second publication) and the like are known.

[0004] In the second publication, an ink reservoir is formed by stacking sheet-like sheets that spread in a flat plate shape, and the sheet-like sheets have a plurality of convex portions formed at appropriate intervals on the surface thereof. And
The convex portion forms a gap for storing overflowing ink by arranging the stacked adjacent sheets at a desired interval substantially in parallel, and all the sheets constituting the gap are formed. Discloses a technique at the stage of assembling a writing instrument that is in contact with an ink conducting path.

[0005] Conventionally, when a single sheet is used as a collector, the work in the step of constructing the stacked single sheets described above is performed by processing a film wound in a roll shape with a press machine and appropriately applying the film to the surface. A single sheet having a plurality of protrusions at positions spaced apart from each other is processed, and the sheet is processed and suctioned one by one by a robot arm and inserted into a shaft body. However, the insertion has to be interrupted after the predetermined number of sheets have been reached, the sheet has to be processed into the next shaft, the insertion has to be started, and the method has to be carried out up to the predetermined number of sheets.

[0006] In the conventional method, a sheet-shaped body pressed by a robot arm is suctioned one by one and inserted into a shaft body. The driving speed of the robot arm used here is generally not high due to pneumatic driving, and therefore, the pressing speed of the single-wafer must be determined in accordance with the speed of the robot arm. In addition, the speed of the robot arm cannot be increased due to the driving method, and therefore, the pressing speed of the single-wafer body is at most 60 strokes per minute, so the number of processing machines must be increased in order to increase the product output. In addition, there was a problem that the initial investment amount would be very large. Furthermore, in the processing of one sheet at a time, the mass is too light or thin and unwieldy, so it has been difficult to cope with a part supply method such as a parts feeder, an air shooter, or manual work.

[0007] Further, the sheet is formed by embossing a plurality of protrusions at positions where the surface thereof is provided with an appropriate interval, and the protrusions are used to form adjacent stacked sheets. Although it is necessary to position them almost in parallel at a desired interval, there is a probability that the projections of the stacked adjacent sheet bodies may overlap with each other when one sheet is inserted. When the protruding portions of adjacent sheet bodies are located at the same position on the plane and overlap with each other, the adjacent protruding sections enter each other, a portion having a smaller interval than a desired interval occurs, and a plurality of gaps of the stacked sheet bodies are formed. Also, there is a problem that a portion having a desired interval and a portion having a narrow interval are mixed and generated.

[0008]
