Description

The present invention relates to a portable device provided with a display and a jog dial input device for controlling a gazing point and a gazing item of the display.

Conventionally, the input apparatus that can move the cursor displayed on the Display Lee in an arbitrary direction, such as a mouse or a touch panel (touch pad) joystick key (button) the jog dial was present. However, mice is limited places that can be used there is a problem that has been separated from the control object having a display. Touch panel limits the shape of the Display Lee body, also costly. The joystick can freely control two degrees of freedom, but conversely, there is a possibility that an unintended degree of freedom may be operated due to an operation error, and is not appropriate depending on the application. Also, since the active part of the device is spherical, the space required for it is close to a square, and the usable space is limited. In addition, since it has a spherical shape, the movable range may be excessive or insufficient. The jog dial and keys (buttons) have a problem that the degree of freedom to control at one time is small.

  Conventionally, in order to set the state of a device, there are a toggle switch, a dip switch, or a lever that can control one degree of freedom to some extent. However, toggle switches and dip switches require a large number of bodies to determine a state that requires a large range as a parameter, and the operator feels bothersome about the settings and visually It is difficult to understand the state. A device such as a lever requires two levers to set two degrees of freedom, and an input device such as a button is required to reflect the setting when it is not desired to reflect the state instantly. Therefore, many input devices are required.

As shown in FIG. 8, the conventional jog dial input device 30 includes an operation member (jog dial) 31 provided so as to be rotatable in a predetermined direction and slidable within a predetermined range in a thrust direction along the axis of rotation 32. A first encoder that detects the rotation of the member 31, a second encoder that detects the movement of the operation member in the sliding direction, a push switch, and the like (for example, see Patent Document 1).
Japanese Utility Model Publication No. 3-50438.

Incidentally, the conventional jog dial input device, since the operation member is provided slidably in the thrust direction along the axis of its rotation, compact having a display. Although it can be incorporated into a device having a certain width such as a thin portable personal computer, it is not suitable for incorporation into a portable device having a small width such as a cellular phone.

The present invention is mainly used in a corner portion of a portable device having a small display such as a mobile phone, supports the device with a palm, and can perform operations such as up / down / left / right / decision only with a thumb or index finger. An object of the present invention is to provide a jog dial input device that can eliminate the need for its own up / down / left / right buttons.

The portable device of the present invention is a portable device including a display, and includes a first displacement axis provided in a casing of the portable device, a frame that is displaced about the first displacement axis, and a displacement amount of the frame. A first detecting means for detecting a second displacement axis, a second displacement axis provided on the frame, a jog dial that is rotationally displaced about the second displacement axis, and a second detection that detects the amount of rotation of the jog dial. And a display control means for displaying a pointer on the display and changing a display position of the pointer on the display based on a detection result of the first detection means and a detection result of the second detection means. The frame is provided at an upper corner formed by a first surface that is a side portion of the housing and a second surface that is an upper portion , and the first displacement axis is the first surface. Interview The jog dial extends in parallel with the second surface, and the jog dial can be disposed at a first protruding position protruding from the first surface and a second protruding position protruding from the second surface. It is characterized by.
