The light guide plate 23 can be visually checked from the top of the drawing).

The lower housing 1 is bounded by the hinge 50.
The weight of the zero part is heavier than the weight of the upper housing 30 part. Since the relatively heavy battery pack 14 is mounted on the lower housing 10, the lower housing 10 is heavier. Of course, by incorporating a heavy unit other than the battery pack 14 into the lower housing 10, the lower housing 10 may be made heavy, or the lower cover 11 and the lower case 12 of the lower housing 10 may be made heavy. Use a heavy material for the lower housing 1
The zero portion may be heavier than the upper housing 30. Due to the weight balance between the lower case 10 and the upper case 30, if the lower case 12 is placed with the lower case 12 facing down in a state where the two cases are folded, the surface of the lower case 12 is substantially flat. In addition, since the center of gravity of the foldable terminal device is lowered, the foldable terminal device can be stably positioned.

Next, the configuration of the light emission notifying section will be described with reference to FIG. The light emission notification unit includes a light emission unit 22 and a light guide plate 23, and the light emission of the light emission unit 22 is controlled by a control circuit unit 39. The light emission unit 22 irradiates the light guide plate 23 with light, thereby folding the terminal device. The light is diffused toward the outside. The light emitting section 22 has, for example, two types of light emitting elements 22a and 22b, the first light emitting element 22a can emit a first wavelength, for example, red light, and the second light emitting element 22b Can emit a second wavelength, for example, green light. Also, the first light emitting element 22a
Are driven to emit light by a first light-emitting drive section 221, and the second light-emitting element 22b is driven to emit light by a second light-emitting drive section 222.

And the second control signal 392 for controlling the second transistor 222a are output to the light emitting unit 22.

Therefore, for example, when a foldable terminal device receives an incoming call, the first light emitting element 2
In a state where the foldable terminal device is charged by driving the 2a to emit red light, the second light emitting element 22b may be driven to emit green light as the light emission notifying unit. Also,
Even when only the first light emitting element 22a is provided as the light emitting notification unit, the light emitting cycle may be different between the time of incoming call and the time of charging, and the switching of the light emitting color and the switching of the light emitting cycle may be appropriately combined. By causing the light to emit light, the user may be able to more clearly distinguish between the time of incoming call and the time of charging. Further, not only at the time of incoming call or charging, but also at the time of receiving e-mail or during a telephone call, the user may be notified of the use state by the light emission notifying unit.

Next, the operation of the foldable terminal device at the time of an incoming call and at the time of charging will be described. [At the time of an incoming call] The foldable terminal device receives the transmitting / receiving antenna 1
3 or an electromagnetic wave radiated from a base station (not shown) by the external antenna 70b.
8 notifies the control circuit 39 that the call has been received. When the incoming call is notified, the control circuit unit 39 activates the control signal 391, turns on the first transistor 221a of the first light emission drive unit 221, applies a voltage to the first light emitting element 22a, The first light emitting element emits red light to the light guide plate 23.
Irradiation. Accordingly, the red light is diffused by the light guide plate 23 toward the outside of the foldable terminal device, and the user is notified of the arrival of the incoming light by looking at the red light.

At the time of charging, the battery pack 14 of the foldable terminal device is connected to the main body side I / F connector 17, for example.
While being charged by the external power supply, the control circuit section 39 detects the charged state by the main body side I / F connector 17. Therefore, the control circuit unit 39 activates the control signal 392, turns on the second transistor 222a of the second light emission driving unit 222, applies a voltage to the second light emitting element 22b, and turns on the second light emitting element 22b. Irradiates the light guide plate 23 with green light. Accordingly, the green light is diffused by the light guide plate 23 to the outside of the foldable terminal device, and the user is notified of the charging by looking at the green light. Further, when the battery pack 14 is fully charged, the control circuit 39 controls the second transistor 22
By turning off 2a, the light emission of the second light emitting element 22b is stopped. The above is the operation of the light emission control at the time of incoming call and at the time of charging.

Next, with reference to FIG. 5, a case where the foldable terminal device is placed on a desk with the opposite surface of the upper housing 30 facing down in a folded state will be described. FIG.
5A is a side view as viewed from the main body side I / F connector 17 side, and FIG. 5B is a right side view. In FIG. 5, the opposite surface of the lower housing 10 (the surface with the battery pack 14)
Faces upward, and the light guide plate 23 faces downward when viewed from information and is hidden by the lower housing 10.
Opposite side surface and opposite side of upper housing (surface in contact with desk)
Has a step d due to the thickness of the upper housing, so that the light guide plate 23 has a clearance without being in close contact with the desk.

Therefore, in this state, when the notification by the light emission of the light emission notifying unit is performed, the light emitted from the opposite surface side of the light guide plate 23 is emitted toward the desk, and the emitted light is emitted from the surface of the desk. The reflected light is reflected from the main body side I / F connector 17 side (arrow in FIG. 5B) when viewed from above the drawing.
And left and right side surfaces (arrows in FIG. 5A). Therefore, even if the folding type terminal device is placed in the opposite direction as shown in FIG. 5, the reflected light becomes visible, so that the light emission notification is achieved. As before,
When the light guide plate 23 is placed on a desk and the surface of the light guide plate 23 is in close contact with the desk, the reflected light does not reflect as shown by the arrow in FIG. I can't.

Next, a case where the foldable terminal device is mounted on the mounting table will be described with reference to FIG. FIG.
FIG. 6A is a diagram in which the foldable terminal device is placed in an open state, and FIG. 6B is a diagram in which the foldable terminal device is placed in a folded state.

It is also possible to charge the battery pack 14 by connecting it to the I / F connector 70a in the mounted state. At this time, since only the lower housing 10 is engaged with the mounting table 75, the foldable terminal device can be opened and closed even in the mounted state. Therefore, when the foldable terminal device is placed on the mounting table 75 regardless of whether the foldable terminal device is folded or opened, the opposing surface of the light guide plate 23 is exposed upward in FIG. The light emission of the unit can notify that an incoming call or charging is being performed.

In the foldable terminal device according to the present invention, the weight of the lower housing 10 is heavy,

According to this foldable terminal device, even when the two housings are folded, light emission is detected from the opposite side (back side) of the second housing from the opposite side. Since the part is visible, the user can check the incoming call state and the charging state from the opposite side (back side) of the second housing. Further, even when the two housings are folded and the opposite surface opposite to the opposing surface on the second housing side is placed in contact with, for example, a desk surface, the light emission notification unit may face downward. Since the top surface of the desk and the surface of the light emission notification unit form a step (clearance), the light emission notification unit irradiates light to the desk top surface, and is opposite to the opposite surface of the first housing side. Side (back side)
From the side, the reflected (indirect) light reflected on the desk surface can be confirmed. In addition, since there is a step (clearance) between the desk top surface and the surface of the light emission notification unit, light emitted from the light emission notification unit to the desk top surface is diffused, and the area of reflected light on the desk top surface is widened, so that visual confirmation is easier. become.
