A folding electric has an upper unit and lower unit. A hinge connects the upper unit to the lower unit. The hinge includes at least a perpendicular opening and closing shaft to open and close the upper unit with respect to the lower unit and a horizontal rotation shaft, fixed vertically to the surface of the lower unit, to rotate the upper unit with respect to the lower unit coming in contact with each other.

Folding electric device having perpendicular and horizontal shafts

A portable communication terminal includes a front case, a plurality of operation buttons, a rubber sheet, and a light-emitting diode. The front case has a plurality of openings. The plurality of operation buttons are placed in the respective openings to operate the portable communication terminal. The rubber sheet fixes the operation buttons from a lower side. The light-emitting diode illuminates the operation buttons. A rib is formed on a lower surface of a casing portion between the openings of the front case. The rubber sheet is interposed between the rib and light-emitting diode.

Portable communication terminal with improved light emission structure

This invention relates to an electronic device or foldable cellular phone set in which boards arranged in two casings bendably connected to each other through a connecting portion are electrically connected to each other by a wireless communication unit using infrared rays or the like. As the wireless communication unit, either an optical method using infrared rays or the like, or a radio wave method using a radio wave can be used.

Foldable cellular phone set

A waterproof structure for an electronic apparatus of the present invention includes keybuttons positioned such that their ends appear via holes formed in the casing of the apparatus. A circuit board is loaded with switches configured to selectively open or close when the keybuttons associated therewith are operated. A sheet member is formed of an elastic material and intervenes between the keybuttons and the circuit board. The sheet member includes, at least in its peripheral portion thereof, a seal portion for preventing water or similar liquid from entering the apparatus and reaching the surface of the circuit board. When the sheet member is pressed between the casing and the circuit board, the seal portion is at least partly pressed against the inside surface of the casing while being subject to a bending load.

Electronic apparatus and waterproof structure therefor

A pushbutton switch mechanism has boardincorporating an electronic circuit thereon, metal sheet contactdisposed on board, a light-transmissive pushbutton disposed in an opening defined in a casing of the electronic device for being pressed from outside, the light-transmissive pushbutton having outer key topand presserformed with rubber sheetfor contacting metal sheet contact, and light-emitting elementsdisposed on boardaround presserfor applying light to a side surface of the presser. Presserhas a conical shape having an upper surface as a bottom surface substantially aligned with a lower surface of key topand a vertex for contacting metal sheet contact. Light emitted from light-emitting elementsis applied to the entire side surface of presser

Illumination structure for pushbutton and electronic device with pushbutton having illumination structure

A wireless apparatus having a foldable structure allowing improved antenna condition when opened with improved convenience is disclosed. A first housing and a second housing coupled by a hinge are freely opened and closed around the hinge. An antenna section for use in wireless communication is coupled to the first and second housings by the hinge such that the antenna section is situated at back of the second housing and is freely opened and closed around the hinge with respect to the second housing. A spring force is applied to the antenna section to rotate it in an opening direction. The antenna section is latched by an antenna latch member to be kept in a closed state. When the first housing and the second housing are opened to a predetermined angle, the latch is released to open the antenna section away from the second housing.

Portable wireless apparatus

A structure of an electronic instrument having operation keys and a manufacturing method thereof, in which a dustproof and waterproof function can be secured by a simple structure, are provided. The structure of the electronic instrument having operation keys provides a cabinet providing an opening part for operation keys, the operation keys that are disposed in the opening part of the cabinet so that each of the operation keys is movable in the orthogonal direction to the front surface of the cabinet, and a resin film that covers the surface of the cabinet and the surfaces of the operation keys in the state that the resin film is not cut on the surfaces of the cabinet and the operation keys, and covers a gap formed between the cabinet and the operation keys, and gaps formed among the operation keys.

Structure of electronic instrument having operation keys and manufacturing method thereof

A control method of operation of a collective packing machine, which packing machine is composed of a main packing machine and an auxiliary packing machine. The main packing machine is in continuous operation while the auxiliary packing machine is in stop waiting operation wherein the auxiliary packing machine is operated in matching and synchronization with the main packing machine. When the auxiliary packing machine is at the stop waiting state, the revolution speed of a main shaft of the main packing machine and the revolution speed of an input shaft of a clutch of the auxiliary packing machine are controlled by comparing and matching therebetween. When an output shaft of the clutch is stopped and operation of the auxiliary packing machine is started, operation starting time of the auxiliary packing machine is made earlier than the normal operation starting time by time t.sub.s. The time t.sub.s depends on the operation speed of the main packing machine so as to enable synchronization of the main packing machine with the auxiliary packing machine at the time of finishing to connect the clutch of the auxiliary packing machine. After finishing to connect the clutch, the main packing machine and the auxiliary packing machine are controlled in synchronization.
