Abstract

When a drive control section of a portable terminal (1) receives a rotational force output command, it outputs a drive control voltage from a source voltage of a battery in a battery section to a rotation motor in a drive section (C). Upon receiving the drive control voltage, the rotation motor of the drive section (C) rotates a rotating shaft to output rotational force to a portable terminal (2). When the rotating shaft is inserted into the portable terminal (1) and portable terminal (2), a rotational force output (reception) mechanism provided at a drive section of each portable terminal is gradually depressed. As a result, a vibrating weight provided at the drive section is receded from the rotation motor and combined with the rotational force output (reception) mechanism and the rotation motor. This enables a rotational force producing device to output rotational force to the outside and to receive rotational force from the outside.

BEST MODE FOR CARRYING OUT THE INVENTION

[0024] Embodiments of a rotational force generator according to the present invention will be described below in detail with reference to the accompanying drawings. In the following description, a case where the rotational force generator according to the present invention is applied to a mobile terminal will be described as a first embodiment, and then another embodiment included in the present invention will be described. Example 1

[0025] In Example 1 below, an outline and characteristics of a case where the rotational force generator is applied to a mobile terminal will be described, and finally, the effects of Example 1 will be described.

[Summary and Features (Example 1)]

First, the outline and features when the rotational force generator is applied to a mobile terminal will be described with reference to FIG. FIG. 1 is a diagram for explaining an outline of a mobile terminal to which the rotational force generator according to the first embodiment is applied. As shown in the figure, the mobile terminal according to the first embodiment is outlined to generate a rotational force, but has a main feature in that a rotational force is automatically generated regardless of manual operation.

[0027] The main features will be specifically described. The portable terminal includes a battery unit, a control unit, and a drive unit. For example, when the mobile terminal 1 and the mobile terminal 2 configured by the same processing unit are connected by a rotation shaft (for example, a bush rod), the control unit (B) of the mobile terminal 1 Detecting the insertion, check whether the selection switch on the drive unit (C) is turned ON or OFF by the user, etc. Then, the control unit (B) of the mobile terminal 1 that has confirmed that the selection switch has been selected OFF, for example, outputs a rotational force output command to the drive control unit to drive the rotational force. Control part (C).

[0028] The drive control unit of the portable terminal 1 that has received this rotational force output command outputs a drive control voltage from the power supply voltage of the battery provided in the battery unit to the rotary motor in the drive unit (C). The rotary motor of the drive unit (C) that has received the drive control voltage outputs rotational force to the mobile terminal 2 by driving the rotary shaft to rotate.

[0029] It should be noted that when the rotary shaft is inserted into the mobile terminal 1 and the mobile terminal 2, the rotational force output (acceptance) mechanism provided in the drive unit of each mobile terminal is gradually pushed down, Similarly, the vibration weight provided in the drive unit is retracted from the rotary motor and combined with the rotational force output (acceptance) mechanism and the rotary motor. As a result, the rotational force can be output to the outside and the rotational force can be received from the outside.

[0030] On the other hand, the control unit (E) of the mobile terminal 2 detects the insertion of the rotating shaft, and the selection switch provided in the drive unit (F) is selected by the user or the like either ON or OFF. Make sure Admit. Then, the control unit (E) of the mobile terminal 2 that has confirmed that the selection switch is turned ON outputs, for example, a rotational force acceptance command to the drive control unit so as to accept the rotational force. The drive unit (D) is controlled.

[0031] The drive control unit of the mobile terminal 2 that has received this rotation force acceptance command receives the rotational force output from the mobile terminal 1, and rotates the rotary motor in the drive unit (D). In addition, a power generation mechanism (not shown) provided in the drive unit (D) generates an electromotive force by the rotation of the rotary motor. Then, the charge control unit of the control unit (E) charges the generated electromotive force to the battery unit (F). The charge control unit controls the generated electromotive force to be directly used by, for example, the power consumption unit (for example, the LED of the display device), which simply charges the battery unit (F). Anyway.

[0032] As described above, according to the first embodiment, using the accumulated electric power, a predetermined rotational driving unit (for example, an electric motor) is electrically driven to rotate to generate a rotational force, Since the generated rotational force is output to another mobile phone, it can be automatically generated regardless of manual operation, and the generated rotational force can be output to another mobile phone. It is possible.

[0033] Also, according to the first embodiment, the device is detachably connected to another device via a predetermined shaft (for example, a rotating shaft that is rotationally driven), and the rotational force is output to the other connected mobile phone. Therefore, it is possible to detachably connect to other mobile phones that want to output rotational force via a predetermined axis.

[0034] Further, according to the first embodiment, a predetermined rotation driving unit (for example, the driving unit (B) of the portable terminal 1) is rotationally driven electrically to generate a rotational force. Since the electromotive force generated by accepting the rotational force of the phone is used, for example, in the mobile phone to which the rotational force generating device is applied, the generated electromotive force is used for charging the battery or the power consumption. It can be used directly in a part (for example, LED of a display device), and the rotational force received from other mobile phones can be used effectively.

[0035] According to the first embodiment, since the rotational force is received or output according to the selection instruction from the user, the rotational force is output by a mechanism such as a selection switch. Or simply accept or output rotational force by letting the user select acceptance Is possible.

Example 2

[0036] Although the first embodiment of the present invention has been described so far, the present invention may be implemented in various different forms other than the first embodiment described above. Therefore, in the following, other embodiments included in the present invention will be described.

[0037] (1) Utilizing rotational force for vibration

In the first embodiment described above, the case where the rotational force is output to another mobile terminal has been described. However, the present invention is not limited to this. For example, as illustrated in FIG. 2, the vibration weight may be vibrated by a rotational force.

[0038] Thereby, when the generated rotational force is not output to another portable terminal, the generated rotational force is vibrated by the generated rotational force. For example, in a mobile phone to which the rotational force generating device is applied. When the rotational force is not output to other mobile terminals, the rotational force can be used as a vibrator function.

[0039] (2) Accepting rotational force and generating control information

Further, control information may be generated by accepting an external rotational force. For example, as illustrated in FIG. 3, when the operation axis inserted by the user is operated, the display control unit of the portable terminal receives the operation received via the drive unit (for example, a stepping motor). Control information is generated from the rotation angle of the shaft, and the cursor operation of the display device is controlled based on the control information.

[0040] Thereby, a control generated by receiving an external rotational force (for example, an operation shaft inserted into a portable terminal) that merely generates a rotational force by electrically rotating a predetermined rotational drive unit. Control information generated from the rotation angle of the inserted operation axis, etc., for example, on a mobile phone to which a rotational force generator is applied, for controlling the operation of the cursor on the display device. It can be used and the rotational force received from the outside can be used effectively.

[0041] (3) Controlling the output or acceptance of rotational force according to the amount of power

In the first embodiment described above, for example, the output or acceptance of the rotational force is controlled by the selection switch. For example, the output or acceptance of the rotational force may be controlled in accordance with the amount of electric power in the battery provided in a part of the battery.

[0042] Thus, the rotational force is received or output according to the accumulated electric energy, and the rotational force is received or output according to the determination result. Therefore, the rotational force generator is applied. In mobile phones and the like, it is possible to receive or output effective rotational force, such as being able to output rotational force from the one with the larger amount of stored electricity to the one with the smaller amount.

[0043] (4) Electrical connection

In the first embodiment, power may be received from the outside (for example, an external power source such as an outlet). As a result, electric power is received from the outside. For example, it is possible to output electric power to other devices (for example, other mobile phones) while receiving electric power and charging.

[0044] (5) Multiple connections

In the first embodiment, the case where the portable terminal that outputs the rotational force and the portable terminal that receives the rotational force are connected on a one-to-one basis has been described. However, the present invention is not limited to this. For example, the portable terminal that outputs the rotational force and the portable terminal that receives the rotational force may be connected one-to-many or many-to-one as illustrated in FIG.

Industrial applicability

As described above, the rotational force generator according to the present invention is useful when generating rotational force, and is particularly suitable for generating rotational force automatically regardless of manual operation.
