| 101 | Portable information terminal | US515955 | 1995-08-16 | US5646649A | 1997-07-08 | Yuji Iwata; Jiro Nakasu; Makoto Takemoto |
| In a unit body of a portable information terminal is assembled a display and a pressure-sensitive input device overlying the display. An opening and closing cover is attached to the unit body for covering the pressure-sensitive input device. An operating button device provided in the cover exposes, when the cover is closed, its operating surface from the surface of the cover. The operating button device exerts a pressing force applied to the operating surface onto the surface of the pressure-sensitive input device. Thus, with the cover closed, major function entry or data entry can be carried out. | ||||||
| 102 | Flexible printed circuit assembly with torsionly rotated conductors | US239105 | 1988-08-31 | US4885430A | 1989-12-05 | Ralph W. Kinser, Jr.; David L. Shriver; Judith A. Layman |
| Conductors of a flexible printed circuit routed through a hollow two axis articulated hinge allow a calculator with rotating case halves to possess a keyboard portion in each half of the case. The conductors routed through the hollow articulated hinge are generally centered about one axis of hinge rotation for approximately half the length of the axis, whereupon they transition by either a U-turn or a jog to continue as centered about the other axis of hinge rotation. The conductors may be an integral part of a flexible membrane keyboard assembly having portions located in both halves of the calculator's case. Strain reliefs at the locations where the conductors traverse the case halves, and two in the hinge, at about the center thereof, limit and apportion the torsional flexing experienced by the conductors. The torsional flexing experienced by the flexible conductors increases the number of cycles of rotation they can undergo without breaking, as compared to conventional bending. The hollow articulated hinge allows one case half to rotate one full revolution about the other, so that the calculator can be opened and held in one hand. By being within the hollow hinge the conductors are protected from injury. | ||||||

| Disclosed herein is a stack-up for an input device. The stack-up may include a flexible substrate having a switch and a light source. The switch has at least two contacts that are bridged in response to actuation of a dome that is positioned above the switch. The flexible substrate includes a signal trace for detecting the actuation of the dome and a power trace for providing power to the light source. | ||||||
| 104 | Mechanism to raise and lower the height of keys within a keyboard | US15220196 | 2016-07-26 | US09847190B1 | 2017-12-19 | Che-Wei Yang |
| A key structure includes a supporting plate, a keycap, a scissors-type connecting element, a movable element and a coupling structure. The keycap is disposed over the supporting plate. The coupling structure is connected with the scissors-type connecting element and the movable element. For operating the key structure, the cooperation of the movable element and the coupling structure allows the keycap to be at a higher first height. Consequently, the tactile feel of depressing the key structure is enhanced. Moreover, the cooperation of the movable element and the coupling structure can lower the height of the keycap. Consequently, the key structure has a slim appearance. | ||||||
| 105 | Keyboard module and electronic device | US15174258 | 2016-06-06 | US09829928B2 | 2017-11-28 | Chien-Hsing Chiu |
| A keyboard module pivotally connected to an electronic device is provided. The keyboard module comprises a bottom plate, a plurality of keys, a keyboard frame and a hinge structure. The plurality of keys are disposed on the bottom plate. The key includes a keycap and a support member for connecting the keycap to the bottom plate. The keyboard frame includes a plurality of openings to expose the keycaps. The hinge structure pivotally connects a display module of the electronic device with the keyboard frame or the bottom plate. When the display module rotates to drive the keyboard frame (or the bottom plate), the keycap moves relative to the keyboard frame (or the bottom plate). An electronic device including the keyboard module is also provided. | ||||||
| 106 | Key structure | US15200451 | 2016-07-01 | US09799467B1 | 2017-10-24 | Yi-Chen Wang |
| A key structure includes a supporting plate, a keycap, a frame and a movable plate. The supporting plate is disposed over the movable plate. The keycap is disposed over the supporting plate. The frame is disposed over the supporting plate and arranged around the keycap. The frame includes a linking element. The linking element is inserted in a groove of the movable plate. While the movable plate is moved, the linking element is moved along the groove in response to the movement of the movable plate and the frame is ascended to a position at the same level with the keycap. Consequently, the top surface of the frame and the top surface of the keycap are collaboratively defined as a flat surface. | ||||||
| 107 | KEYBOARD AND NOTEBOOK COMPUTER WITH SAME | US15161009 | 2016-05-20 | US20170277227A1 | 2017-09-28 | YI-TE CHOU; YI-CHEN WANG |
| A keyboard and a notebook computer with the keyboard are provided. The keyboard includes a membrane circuit board and plural keys. Each key includes a keycap, a bulge and a key frame. The bulge is connected with the keycap. The key frame has a guiding groove corresponding to the bulge. When the keyboard is in a usage status, the bulge is not pushed by the guiding groove and thus the keycap is at a higher position. Since the keycap is at the higher position, the movable distance of the keycap is increased and the tactile feel of depressing the keycap is enhanced. While a top cover of the notebook computer is closed to cover the keyboard, the key frame is moved horizontally. As the bulge is pushed by the guiding surface of the guiding groove, the height of the keycap is lowered. | ||||||
