    Abstract: A Personal Digital Assistant (PDA) with retractable stylus comprises a retractable stylus, a housing, a stylus slot, and a push portion, wherein a contact pad is attached to the inner side of the push portion. The retractable stylus comprises a pen shaft having a release button, a pen body having an opening, and a spring situated inside the pen body. When an external force is applied to the pen shaft downward, the spring is compressed until the opening holding the release button; thus, the stylus is shortened. When the release button is set free from the opening, the spring elasticity ejects the pen shaft upward; thus, the stylus returns to the full-length condition. If the stylus is kept in the stylus slot, an external force applied to the push portion can make the contact pad press the release button; so the pen shaft is ejected upward by spring elasticity.

  • Patent number: 6227743
    Abstract: A pen cap stylus (or screen operator) is useful in combination with a conventional writing implement, such as a pencil or an ink pen. The manner in which the pen cap stylus screen operator engages to an end of a writing implement is analogous to how a pen cap engages either end of the pen for which it was designed. To form a hybrid instrument for use both as a computer stylus and as a writing instrument, the pen cap stylus is placed on the end of the writing instrument opposite the writing element. The pen cap stylus has a pointy tip for engaging a touch screen of a computer device to selectively actuate microswitches therein. The writing element disposed at the other end of the writing instrument maintains its conventional utility.

  • Patent number: 6106180
    Abstract: A handwriting or ink applying device includes a casing for holding a flexible ink container, the casing having a writing tip at a writing end thereof The rear end of the writing tip communicates with an L-shaped ink-containing chamber. The ink-containing chamber has a valve interposed between the ink container and the chamber. The valve is connected to a spring biased lever arm that biases the valve into a closed position. A flexible bubble having an interior communicating via a channel with the ambient air is responsive to pressure differences between the ambient air and the interior of the chamber to open and close the valve as the level of ink in the ink-containing chamber rises and falls.

  • Patent number: 5445466
    Abstract: First and second engaging projected portions are formed on opposing circumferential surfaces of a tubular casing and a hollow lead portion which are rotated relative to each other so as to be coupled with, thereby spirally engaging external and internal threads formed on the respective opposing circumferential surfaces. A forward side face of the first engaging projected portion with respect to a spiral rotating direction is formed into a slanting face so as to allow the second engaging projected portion to move over the first engaging projected portion when the casing and the lead portion are completely coupled with each other. Further, backward side faces of the first and second engaging projected portions are formed into upright faces, such that the second engaging projected portion cannot move over the first engaging projected portion in an opposite direction once moving over the same. This arrangement reliably prevents the spiral engagement of the casing and the lead portion from loosening.

  • Patent number: 5443322
    Abstract: A writing or drawing instrument including a writing tip (1) disposed at a front end of the writing instrument which can be brought into contact with a writing or drawing pad, a writing fluid reservoir (7) for supplying the writing tip (1) with writing fluid, and a writing fluid chamber (9) disposed between the writing tip (1) and the writing fluid reservoir (7). The writing fluid chamber (9) consists of a bubble of a flexible, inelastic material. The writing fluid chamber (9) is connected to the writing tip (1) on one side and is connected on the other side to a barrier (12). The barrier (12) is connected with the writing fluid reservoir (7) and can be opened in a controlled manner. When a lower fill level is reached in the writing fluid chamber (9), the barrier is briefly opened to fill the writing fluid chamber (9). During the filling of the writing fluid chamber (9), the volume of the writing fluid reservoir (7) is reduced in accordance with the consumption of the writing fluid.

  • Patent number: 5427463
    Abstract: An ink writing implement has a front part with a writing tip that comes into contact with the writing substrate, and a writing fluid cartridge whose interior chamber containing the writing fluid is tightly sealed before being put into use, and which is connected to the front part during use. There is also provided an equalization system disposed inside a housing and connected by one end to the interior chamber of the writing fluid cartridge and by the other end with the outside air. The writing fluid cartridge and front part are rigidly attached to one another. The front part can be inserted into the equalization system through a back opening and moved into a position in which it protrudes beyond the front opening in the housing.

  • Patent number: 5352051
    Abstract: This invention relates to a writing instrument wherein a temporary ink storage member made of a synthetic resin injection molded article is sandwiched between a pen tip and an ink tank. In the present invention, a flange portion for fitting to a predetermined apparatus, which is positioned around an outer peripheral portion of the temporary ink storage member, is formed integrally with a shaft made of a synthetic resin injection molded article. In embodiments of the invention, the temporary ink storage member is made flexible, the shaft is made of a material which is softer than that of the tip holder, and the tip holder is used as a writing thickness display member. The temporary ink storage member can be used as an ink color display member and a cap is used as an application display member. In other embodiment, the cap can be fitted selectively in accordance with types of writing instruments.

  • Patent number: 5336007
    Abstract: A technical pen, in particular for use in a drafting instrument such as a plotter, with a writing tube (4) fixed in the front end of a pen tip (1, 2, 3), into which a cleaning wire (5), fastened to the front end of a drop weight body (6), extends, has a device (20, 23, 24) for monitoring the writing fluid level in a buffer chamber (15) disposed between the front end of the inner bore (7) and the back end of the writing tube (4) as well as for activating a conveying means (25) for transporting writing fluid from the inner bore (7) into the buffer chamber (15) when the writing fluid has fallen below a pre-determined level. The buffer chamber (15) is formed centrally symmetrical in relation to the center axis of the writing tube (4) and its inner and outer boundary walls (16, 17) converge from the front to the back. The front area of the buffer chamber (15) is connected with the writing tube ( 4) and the inner bore (7), while its rear area is closed.

  • Patent number: 5211495
    Abstract: A writing or drawing instrument wherein a housing (1), is provided with a writing point (2) and a writing fluid reservoir (3) within an interior space of the housing. A capillary pressure equalization system (5), that connects the reservoir with the ambient air, has a sensor (7) therein for reacting to the level of writing fluid (4) therein. A suction pump (11, 12) is connected with the writing fluid reservoir (3) through a semi-permeable membrane (10) which lets air through and is impermeable for writing fluid (4). The suction pump (11, 12) is activated by the sensor (7) in response to a level of writing fluid (4) in the pressure equalization system, and aspirates air from the reservoir so as to quickly reduce an overpressure condition.
