Description

  The present invention relates to an electrostatic input pen used in a capacitive input device that allows selection or movement of a cursor by touching an operation area with a tip of an input pen.

  Conventionally, as described in Patent Document 1, there is known an electrostatic input pen in which a tip tip made of conductive rubber is provided at a front portion. Also, recently, as described in Patent Document 2, a thin touch panel type input device that is used by hand is gaining popularity in the market, and not only performs input with a fingertip but also a writing instrument. There is also a growing demand for an electrostatic input pen that can hold a shaft member for input.

  In addition, in such an electrostatic input pen, a tip end made of conductive rubber is provided on one end side of the shaft tube, and a writing body such as a ballpoint pen is provided on the other end side, to the input device. There is an input pen with a structure that can write not only on the screen but also on paper. However, in the input pen structure with a conventional cursive body, the tip and the cursive body exist separately on the front and back of the shaft tube, so it is inconvenient to change the front and back of the shaft tube when using both. In addition, a cap is attached to the writing tip so that the writing tip of a ballpoint pen or the like protrudes and there is no danger, or the surroundings are not soiled, and there is a problem that the cap must be detached and attached at the time of use.

  Patent Document 3 describes a structure in which a grip having a tip as a touch pen is attached to the front of a mechanical pencil. In this structure, the touch pen and the mechanical pencil are selectively used without changing the front and rear of the barrel. However, since the grip for the touch pen is further stacked on the outside of the shaft of the mechanical pencil, the appearance of the touch pen deteriorates and the position of the center of gravity changes, so that the balance of the shaft tube is lost and the writing feeling is lost. There is a risk of damage. Further, the structure of Patent Document 3 is not configured to be used for a capacitance type input device, and its use is for a pressure-sensitive touch panel.

Japanese Patent No. 4142276 JP 2011-81825 A Japanese Patent No. 3398679

  The present invention solves the above-mentioned conventional problems, and can perform writing on a paper surface with a cursive body as well as input to a capacitance-type input device, and use of input and writing properly. It is an object of the present invention to provide an electrostatic input pen that can perform the above operation without changing the front and rear of the shaft cylinder.

“1. Operation of the input device by the front opening formed from the conductive rubber of the shaft cylinder in a state where the writing body is accommodated in the shaft cylinder so as to be able to appear and retract by a feeding mechanism and the writing body is accommodated in the shaft cylinder This is an electrostatic input pen that enables input to a region and allows writing on the paper surface by the writing tip in a state where the writing tip of the writing body protrudes from a tip opening formed in the front end portion. An inner opening having a holding hole for forming the space inside the front opening and holding the writing body is formed inside the front opening, and the front opening serves as an operation area of the input device. When the abutment part is brought into contact, the tip part is elastically deformed and brought into surface contact, and in a state where the writing tip of the writing body is projected from the tip opening of the tip part, the writing body is An electrostatic input pen with a structure that is held at the tip and used as a steady rest.
2. 2. The electrostatic input pen according to item 1, wherein the outer shape of the front opening is formed in a dome shape having the tip opening at the tip.

  The cursive body in the present invention is a ballpoint pen refill, a mechanical pencil unit, a solid core, a marker, or the like. Since the inside of the shaft communicates with the outside, a ballpoint refill or a mechanical pencil unit containing oil-based ink or gel ink is preferable. In addition, in most of the recent capacitance type input devices, the input reaction is shown when the contact area is 16 square millimeters or more. However, the thickness of the tip portion formed of conductive rubber is reduced. By setting the hardness low, the front opening can be easily crushed toward the inner space, and the contact area between the front opening and the input device can be increased even with a small load. Specifically, it is preferable to form the tip portion in a dome shape with a thickness of 0.3 mm to 0.75 mm using a conductive rubber having a rubber hardness of 10 to 30 determined according to JIS-K6253: 2006. If the thickness is too thin, it is easily deformed but easily broken. If the thickness is too thick, it is difficult to break but difficult to deform. Further, the inner front opening can be provided at the front portion of the inner shaft disposed inside the front shaft. It is important to note that when the cursive body is held by a tip that is easily deformed, the cursive body will be applied to the inner front end provided inside the front end. By making it contact, it is making it the structure which can hold | maintain this cursive. Therefore, the inner tip is preferably made of a hard material. As the coating film provided on the front shaft surface, a coating agent in which a solid lubricant such as molybdenum disulfide, polytetrafluoroethylene, graphite, or boron nitride is contained in a binder is suitable.

  In the electrostatic input pen of the present invention, not only is the input made by bringing the tip into contact with the capacitive input device, but also the writing tip of the writing body is projected from the tip to the paper surface. In addition, it is possible to properly use the input and writing without changing the front and rear of the shaft tube. Further, by providing a space portion inward of the front end portion so that it can be elastically deformed, the front end portion easily comes into contact with the operation area of the input device. Further, by providing the inner front end inward of the front end portion, the cursive body can be firmly held by the inner front end rather than holding the cursive body by the front end portion which is easily deformed.
