Description

  The present invention is suitable for application to a portable terminal in which a first casing and a second casing are connected to each other by a connecting portion so as to be opened and closed.

2. Description of the Related Art Conventionally, in a portable terminal such as a mobile phone, a foldable type in which two casings are rotatably connected via a connecting portion has been widely used. For example, the lower housing (first housing) is held by the user's hand when using the mobile terminal, and has an operation unit provided with a large number of input keys and function keys on the surface. An upper casing (second casing) having a display unit (LCD) on the surface is known.
According to this portable terminal, the portable terminal can be opened and closed by rotating the first casing and the second casing around the connecting shaft from the state where the first casing and the second casing are closed. .

In such a portable terminal, the user holds the first casing with one hand and rotates the second casing with the other hand around the connecting shaft, thereby allowing the first casing and the second casing to rotate. I often open my body.
At this time, many users hold the tip of the user's finger so as to sandwich the first housing in the width direction from the vicinity of both ends of the connecting portion.

However, since recent portable terminals have been reduced in size and thickness, it is difficult for a user to hold only the first casing with one hand, and the first casing and the second casing are held at the same time. There is a possibility.
In this state, for example, when the second housing is rotated with the other hand, even the second housing is pressed down by one hand, and thus there is a disadvantage that the opening operation is hindered.

In addition, a portable radiotelephone has been proposed in which convex grip portions are provided on both side surfaces substantially in the center in the longitudinal direction of the first housing (see, for example, Patent Document 1).
According to the portable terminal of Patent Literature 1, it is supposed that the housing can be gripped by the grip portion.

Conventionally, like the mobile terminal 100 shown in FIG. 6, the hinge portion 103 that connects the upper housing 101 and the lower housing 102 is a pair of support portions provided at both ends in the width direction of the lower housing 102. 104, a rotating shaft member (not shown) is sandwiched inside the support portion 104, and an exterior 105 that covers the rotating shaft member is made part of the upper housing 101, or the rotating shaft member is the upper housing. It was configured to be fixed to the body 101.
In such a portable terminal 100, the exterior 105 that covers the rotation shaft member of the hinge portion 103 is disposed at the center in the width direction of the upper housing 101 and the lower housing 102, and thus When the casing 101 is opened, even if the exterior 105 rotates with respect to the lower casing 102 following the upper casing 101, it is the touch of the lower casing 102 that touches the user's hand that supports the lower casing 102. The user's hand is not caught by the exterior 105 which is an end surface of the integrated support portions 104 and 104 and rotates following the upper casing 101.

However, the portable terminal of Patent Document 1 is such that the grip portion is formed with a level difference from the arrangement surface of the operation portion in order to avoid the user's hand holding the first housing from being placed on the operation portion. It is not taken into consideration that a person's hand gets a finger on the rotating shaft member.
Further, the problem that the user's hand gets on the rotating shaft member and hinders the opening and closing operation is that the rotating shaft member of the hinge portion 103 is connected to the upper housing 101 and the lower case as in the portable terminal 100 shown in FIG. Although it does not occur when it is arranged at the center in the width direction of the case 102, for example, when the rotation shaft member is arranged at the end in the width direction of the upper case 101 and the lower case 102 due to design or design restrictions It becomes a problem.

Even in the case of arrangement, it is possible to prevent the user's hand from being caught when the second casing is opened with respect to the first casing.

  Further, according to the present invention, the connecting portion includes an opening operation portion on one end side of the first rotating shaft in order to open the first housing and the second housing from a closed state, and the convex portion includes: It is formed at the other end of the opening operation part.

  In such a configuration, since the convex portion is formed at the other end of the opening operation portion, when operating the opening operation portion, the user moves his / her finger along the convex portion to The user's finger is not caught on the rotating second casing, and a smooth opening operation is obtained.

  In such a configuration, the first rotating shaft and the second rotating member can be vertically and horizontally opened, and the convex portion is formed on the side surface of the end portion to which the connecting portion is connected. Even when the members are arranged at the end portions in the width direction of the first casing and the second casing, the user's hand can be prevented from being caught when the second casing is opened with respect to the first casing.

  Further, according to the present invention, the connecting portion includes an opening operation portion on one end side of the first rotating shaft member in order to open the first housing and the second housing from the closed state, and the convex portion It is provided on the opposite side to the opening operation part.

  In such a configuration, since the convex portion is formed at the other end of the opening operation portion, when operating the opening operation portion, the user moves his / her finger along the convex portion to The user's finger is not caught on the second casing that rotates for vertical opening, and a smooth opening operation is obtained.

  Furthermore, the present invention is characterized in that a strap hole is formed in the convex portion.

  With this configuration, the convex portion can be used effectively.

  According to the portable terminal of the present invention, since the convex portion is formed on the side surface of the end portion to which the connecting portion in the first casing is connected, the first casing and the second casing are smoothly moved around the rotation axis. By rotating, the opening operation can be easily performed.
