Embodiment Construction

[0063] The fingertip tactile input device of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a sectional view showing one embodiment of the fingertip tactile input device of the present invention. FIG. 2 is a cross-sectional view of the fingertip tactile input device of FIG. 1, showing an operating state. Figure 3 is a design drawing of the surface sheet.

[0064] As an embodiment of the fingertip tactile input device of the present invention, it is provided with a frame 10 , a substrate 50 , a surface sheet 20 , a digitizer 30 and an actuator 40 .

[0065] The frame 10 has an open space opened at the center, and a flange 11 extending from an inner wall surface to the open space. The frame 10 may be slightly larger than the surface sheet 20, but the frame may be part of the structure of the device in which it is used. The open shape of the open space of the flange may be a circle, an ellipse, or an oval, and may also be an opti...

Abstract

To provide a fingertip tactile-sense input device in an input device having a plurality of keys within an extremely small range such as within a range of person's fingertip movement, which while being made extremely small and thin, enables key input while maintaining a sufficient click feeling, and also which is excellent for mass production. A base plate (50) has one dome spring (51) arranged at an approximate center of a side of a hole space, and a contact structure (52) on an inside of the dome spring (51). A surface sheet (20) is fixed to a flange (11) so that in a free state, this becomes approximately the same level as an other face of a frame (10), and is provided with a plurality of surface protrusions (21) deployed within a range in which the person's fingertip moves, and has flexibility, elasticity, and pliability. A digitizer (30) is arranged on the hole space side of the surface sheet (20), so as to be slidable on the surface sheet (20), and is capable of electrically measuring a position where a force applied to the surface sheet (20) is the strongest. A convex part (41) is provided on an actuator (40), and the actuator (40) is fixed to the digitizer (30), and has rigidity.

Description

technical field [0001] The present invention relates to a fingertip tactile sensation for use in personal digital assistants including mobile phones, or in compact electronic devices such as remote controls, walkmans, mice, electronic organizers, game consoles, or medical devices An input device that uses the touch of a fingertip to input numbers or characters, patterns or positional information. Background technique [0002] Currently, personal digital assistants are very popular. Using small terminals such as mobile phones can not only carry out traditional telephone conversations, but also communicate with letters and symbols used in inputting emails, etc., and exchanging interactive information through the Internet is becoming more and more popular. frequently. [0003] However, in a conventional keypad input, a keypad input device is constructed centering on keypad buttons corresponding to number buttons in a conventional telephone, resulting in limitations in miniatur...
