  • Publication number: 20150030388
    Abstract: A bundling tool includes first and second bundling members in plate like shapes. The first and second bundling members respectively include central parts that cover wires, first locking parts that are bendable and extend from first sides of the central parts, and second locking parts that are bendable and extend from second sides of the central parts. When the first and second bundling members clamp the wires therebetween and are to be crimped, the first and second locking parts of the first bundling member are each folded down to abut on an outer surface of the second bundling member at an end part of the locking part, and the first and second locking parts of the second bundling member are each folded down to abut on an outer surface of the first bundling member at an end part of the locking part, thereby crimping the wires.

  • Patent number: 8188388
    Abstract: A small-sized operation key, permits various kinds of inputs by a user to be detected and imparts the user with a tactile sensation in correspondence with each input to enable him/her to recognize his/her input. An operation key has a dome-like structure, a pressure detecting portion, a sheet member placed on the dome-like structure and pressure detecting portion, having a plate-like portion, and further having at least one first pusher and at least one second pusher formed on the lower surface of the plate-like portion, and an operating portion provided on the upper surface of the sheet member. In the operation key structure, the dome-like structure and the first pusher face each other and the pressure detecting portion and the second pusher face each other, and an initial load is applied to the pressure detecting portion by the second pusher.

  • Publication number: 20100006410
    Abstract: [PROBLEMS] To provide a small-sized operation key, in which various kinds of inputs by a user can be detected and that imparts the user with a predetermined tactile sensation in correspondence with each input to enable him/her to recognize his/her input. [MEANS FOR SOLVING PROBLEMS] An operation key has a dome-like structure, a pressure detecting portion, a sheet member placed on the dome-like structure and pressure detecting portion, having a plate-like portion, and further having at least one first pusher and at least one second pusher formed on the lower surface of the plate-like portion, and an operating portion provided on the upper surface of the sheet member. In the operation key structure, the dome-like structure and the first pusher face each other and the pressure detecting portion and the second pusher face each other, and an initial load is applied to the pressure detecting portion by the second pusher.

  • Patent number: 7405777
    Abstract: This invention provides an electronic apparatus having a back display portion and a back LCD impact absorbing structure capable of preventing a front LCD from being broken through a back LCD by a load applied from a rear cover. A rear cover has a back screen attaching portion to which a back screen is attached and a back LCD display window opened by being surrounded by the back screen attaching portion on the surface and a back dustproof cushion on the back of the cover. The longitudinal one side in four sides of a back LCD display window which forms a cutout portion is broadened like a half-moon shape and thereby, a direct influence on this portion of a back LCD due to an external force added to the rear cover is moderated.

  • Patent number: 7101232
    Abstract: A mobile terminal device includes a key side housing having operation buttons and a display side housing having a liquid crystal display module. The key side housing and the display side housing are coupled by a hinge device to be folded free. The key side housing consists of an upper case, a lower case and a printed circuit board. The upper and lower cases are engaged to each other to be opened or closed, and fastened to each other with screws 10 passing through the printed circuit board. The external connection terminal fixing structure of the mobile terminal device consists of external connection terminals which are fixed to the printed circuit board and charge terminals overlapped with the external connection terminals. The charge terminals are thick enough to bridge the gap between the external connection terminals and the upper case.

  • Patent number: 6982698
    Abstract: The present invention provides an LCD dustproof structure which corresponds to dustproof and impact absorption by one cushion and is easily assembled and an electronic apparatus having the structure. A board protruding portion extending to right and left is set in the width direction of an LCD flexible board, an LCD flexible board catching face contacting with the downside of the board protruding portion of the LCD flexible board is formed on an LCD frame, when assembled, the downside of the board protruding portion of the LCD flexible board contacts with the LCD flexible board catching face, so that the board protruding portion and the upside of the LCD flexible board constitute planes continued with the face of a cushion striking portion. Thereby, it is possible to secure the dustproof of the space between a screen and an LCD body only by a dustproof cushion and at the same time, the cushion serves as an impact absorbing cushion.
