Description

  The present invention relates to a sliding portable terminal device in which a display unit and an operation unit slide relative to each other.

  As a conventional sliding mobile terminal device, there is a main body portion provided with a liquid crystal display section for displaying predetermined information on the screen on the front surface, and a key operation section for inputting predetermined information by a user key operation on the front surface. A slide mechanism is provided on the body part and the slide part so that the slide part slides so as to cover the liquid crystal display part of the body part. There are guide grooves that are formed on both side surfaces or slide portions of the main body portion, and guide rails that are fitted to the guide grooves on both side surfaces or the slide portion of the main body portion (for example, patents). Reference 1).

  Further, as a conventional sliding mobile phone, in the sliding mobile phone comprising an upper housing and a lower housing, the upper housing and the lower housing are mutually coupled so that the upper housing and the lower housing can be relatively slid in a linear direction. At least one slide module; and a connecting member for electrically connecting a circuit board attached to the housing and a circuit board attached to the lower housing, wherein each of the at least one slide module includes A slide member having first and second fixing portions for coupling with the lower housing, and allowing the upper housing and the lower housing to slide relative to each other; and a housing fixed to the upper housing and housing the slide member Together with the plate and the receiving plate Supporting the id member, there are included therein the slide member guide plate guide hole is formed for guiding the slide (e.g., see Patent Document 2).

  However, the conventional sliding portable terminal device disclosed in Patent Document 1 is provided with a guide groove or a guide rail that fits into the guide groove on both side surfaces of the main body provided with the liquid crystal display unit. In the open state, the guide groove or the guide rail was exposed. For this reason, there is a problem that the foreign material is inserted into the guide groove or the guide rail is damaged, and the sliding portion cannot be smoothly slid and the durability is low.

  In addition, the conventional sliding mobile phone disclosed in Patent Document 2 includes a slide module that allows the upper housing and the lower housing to be coupled to each other so that they can slide relative to each other. This slide module is coupled to the lower housing. And a slide member that allows the upper housing and the lower housing to slide relative to each other, a receiving plate that is fixed to the upper housing and receives the slide member, supports the slide member together with the receiving plate, and slides It has a guide plate in which a guide hole for guiding the slide of the member is formed, and the number of parts is large, so that the assemblability is poor, and the thickness of the slide module is too large to make the mobile phone thin. was there.

  The present invention has been made in view of the above, and an object of the present invention is to obtain a thin slide-type mobile terminal device having a small number of parts, high durability of the slide portion, and a thin shape.

  In order to solve the above-described problems and achieve the object, a sliding portable terminal device according to the present invention includes an operation unit casing on which a key operation unit is formed, a display panel protection frame that holds a display panel, and the display. A slide-type portable terminal device that includes a display unit housing that houses a panel protection frame and slidably engages with the operation unit housing, and a rail guide is integrally formed on the operation unit housing, and the display A rail portion that is slidably engaged with the rail guide is integrally formed on a panel protection frame, and a skirt portion that covers the rail guide and the rail portion from the outside is provided on the display unit housing.

  According to the present invention, the rail guide is integrally formed with the operation unit casing, the rail part is integrally formed with the display panel protection frame, and no separate slide module is required. Can be made thin. Further, since the rail guide and the rail portion are covered with the skirt portion from the outside, foreign matter is not inserted into the rail guide and the rail portion is not damaged.

  According to the present invention, there is an effect that a slide type portable terminal device with a small number of parts and a thin shape and high durability of the slide portion can be obtained.
