摘要： PURPOSE:To provide the portable telephone set of a folding system, which is provided with a function that automatically executes an antenna drawing operation at the time of a call by means of a spring driving system by interlocking it with the opening operation of a case. CONSTITUTION:A spring storage case unit 5 where the external end part of a spiral spring 6 is fixed at the base of an antenna 2 is installed at an upper opening/closing case 10, and the internal end part 6a of the spiral spring 6 is fixed to a fixing boss 10a. Thus, the antenna 2 is pressed into the upper opening/closing case 10 and therefore the spring storage case unit 5 rotates, the spiral spring 6 is wound and repulsion force is given. At the same time, a rod stopper 13 operates and the rotary operation of the spring storage case unit 5 is restricted. A lock lever 12 is the stopper when a lower opening/closing case 17 is closed. Thus, the lock lever 12 and the rod stopper 13 interlock by pushing a lock button 11. Then, the antenna 2 is drawn to an external part as soon as the case is opened.

摘要： PURPOSE:To provide a case structure with improved waterproof property and impact resistance for which a number of components and assembly man-hours for holding internal packaging components are reduced and an internal packaging capacity is large in a portable communication equipment and a portable information processor. CONSTITUTION:An upper inner side case body 3b and a lower inner side case body 4b using soft resin are integrally formed on the inner side of respective upper outer side case body 3a and lower outer side case body 4a using hard resin, an opening part is provided with a difference in level and the upper inner side case body 3b is provided with a notched part 3c. At the time of combining the upper outer side case body 3a and the lower outer side case body 4a, by pushing with the lower inner side case body 4b, the inner packaging component 5 is held. At the time, since the lower inner side case body 4b is large, it is deformed and presses the inner packaging component 5.

摘要： PROBLEM TO BE SOLVED: To reduce the no. of components to improve the assembling work efficiency and reduce the manufacturing cost by casting Al to form an integrated partition surrounding circuit regions on a printed wiring board in a frame and mounting the wiring board on the partition. SOLUTION: A printed wiring board 3 has circuits 4a-4f and through-holes communicating with screw holes of a partition 5 to fix the board 3 to the partition 5 by screws 6 in the through-holes. Only mounting the wiring board 3 on the partition 5 of a lower housing 2 causes gaps between the circuits 4a-4f on the wiring board 3 to be shielded. The increase of the contact area of the wiring board 3 with the partition 5 enhances the shield effect. The partition 5 is integrated with the lower housing 2 by the Al diecasting to reduce the no. of components, work man-hour and product cost.

摘要： PURPOSE:To automatically extend an antenna at the time of talking and retract the antenna into a casing at the end of talking while interlocking with the opening/closing operation of a hinge by means of the gear driving system. CONSTITUTION:One end 20a of an opening/closing spring 20 is fixed to an upper opening/closing casing 5 and the other end 20a is fixed to a lower an opening/closing casing 7 respectively. When the casings 5, 7 are closed, the an opening/closing spring 20 is wound up. A fixed gear 21 is fixed to the lower opening/closing casing 7, a gear unit 9 and a 3rd gear 17 are fitted to the upper opening/closing casing 5, a timing gear 25 fixed with an antenna 2 is mounted to the upper case cover 24, and when the upper case cover 24 is mounted to the upper opening/closing casing 5, the rotation motion of the fixed gear 21 is transmitted as a straight line motion to the timing gear 25. Furthermore, an electronic component housing chamber 30 is partitioned from the antenna housing chamber 29 by using barriers 5b, 24a.

摘要： PROBLEM TO BE SOLVED: To almost uniformly guide light emitted from a back light into all over a liquid crystal panel by dispersing a particulate reflective material in a face part facing the back face of the liquid crystal panel. SOLUTION: The light guide plate is produced by molding an acrylic resin as the mother material into one body in such a manner that the body has a horizontal face 40 and walls 41 dropping downward from the both ends of the face 40, the corners 42 formed by the outer faces of the walls 41, 41 and the upper face of the horizontal part 40 are chamfered and reflective films 6, 7 consisting of an aluminum vapor deposition film are formed on the chamfered corners 42 and on the lower face of the horizontal face 40. A reflective material 8 in a particle state consisting of aluminum is dispersed in the horizontal face 40 facing the back face 20 of a liquid crystal panel 2. The end of the light guide plate is provided with a locking piece to lock and position the liquid crystal panel 2. Since the quantity of light form a light source can be decreased in this structure, the consumption of a battery, for example, of a mobile terminal or the like can be suppressed to low.
