Embodiment 1

[0017] FIG. 1 is a front view showing the appearance of a cellular phone of Embodiment 1. As shown in FIG. Here, Fig. 1(a) shows the state where the upper case is opened relative to the lower case of the two double-folded cases with the hinge part as the axis, and Fig. 1(b) shows the state where the upper case is closed .

[0018] In FIG. 1 , 1 is the lower case of the foldable mobile phone, and 2 is the upper case of the mobile phone, and adopts a structure that can be freely opened and closed around the hinge part 10 . Here, the hinge portion 10 side end of the lower case 2 is provided with a cutout so as not to cover the sub-display portion 7 of the lower case.

[0019] 3 is a microphone arranged at the front lower end of the lower casing 1 for converting the caller's voice into an electrical signal; 4 is a speaker arranged at the front upper end of the upper casing 2 for outputting the voice of the other party; 5 is A selector, which is provided on the lower case 2, and ...

Embodiment 2

[0033] FIG. 3 is a front view showing the appearance of the cellular phone of Embodiment 2. FIG. Among them, Fig. 3(a) shows the state of opening the upper case relative to the lower case in the two double-folded cases with the hinge part as the axis, and Fig. 3(b) shows the state of closing the upper case. In FIG. 3, the same symbols as those in FIG. 1 denote the same or corresponding parts.

[0034] In Embodiment 2, the cutout portion 2c of the upper case 2 is provided so as not to cover the sub-display portion 7 when the case is closed. In other words, in the state where the lower case 1 and the upper case 2 are folded and closed in half, on the lower case 1 on the side opposite to one surface of the upper case 2, a hinge portion 10 is provided near the hinge portion 10. Sub-display 7 for displaying characters or images. On the other hand, the upper case 2 is provided with a cutout at a position overlapping the sub-display 7 in a state where the lower case 1 and the upper...

Embodiment 3

[0038]Fig. 4 is the front view showing the external appearance of the portable phone of Embodiment 3. Fig. 4(a) shows the state where the upper case is opened relative to the lower case in the two double-folded cases with the hinge part as the axis. Fig. 4(a) b) shows the state of closing the upper case. In FIG. 4, the same symbols as those in FIG. 1 denote the same or corresponding parts.

[0039] Although the portable phone of FIG. 4 is basically similar to the portable phone of FIG. 1, no selector is provided in the exposed portion 5 and a larger sub-display portion 7 can be obtained.

[0040] In the embodiments described above, the sub-display part is arranged in such a way that it overlaps on the axis of the hinge part and protrudes upward or / and lower outside from the projected area of ​​the hinge part extending along the axis of the hinge part. Therefore, it is possible to reduce the restriction on the size of the display portion caused by the provision of the hinge po...

Abstract

A cell phone, comprising a first casing (1), having an opposed face opposed to one face of a second casing (2) in the state of the first casing (1) and the second casing (2) folded into two parts, and the second casing (2) rotatably connected to each other through a hinge part (10), the first casing (1) further comprising a display part (7) positioned on the opposed face side near the hinge part and displaying letters or images on an exposed part exposed through the second casing (2) in the two-folded state, the second casing (2) further comprising a cutout part at a position overlapped with the exposed part in the state of the first casing (1) and the second casing (2) unfolded about the hinge part (10), whereby the display part can be used even when the first and second casings are closed or opened and, since the display part is provided so as to be overlapped with the axis of the hinge part, a large display part can be provided.

Description

technical field [0001] The present invention relates to a mobile phone capable of effectively using a display unit. Background technique [0002] Today's portable phones are expected to be pocketable products. Among them, foldable mobile phones with excellent operability are widely used because they are folded for carrying and opened for use to ensure the size of the display and buttons. [0003] However, the foldable portable phone is inconvenient in that when folded, the main display portion cannot be seen from the outside, and necessary information related to incoming calls and the like cannot be quickly seen. Therefore, there is a mobile phone in which a sub-display is provided on the outer surface of the casing so that minimum information can be seen even when the phone is in a folded state when a call is made or the like. [0004] In the conventional mobile phone provided with the above-mentioned sub-display unit, although a small amount of information can be seen in...
