In a wearable electronic device attachable to an arm, a display screen is disposed on a top face of a main body which is attached to the arm. First and second controls are arranged adjacent to opposite sides of the display screen, respectively, and project obliquely from the top face of the main body. The first control is configured to move toward a near side of the display screen by an operation of the user and to return spontaneously to a rest position away from the near side. The second control is configured to move toward a near side of the display screen by an operation of the user and to return spontaneously to a rest position away from the near side. An operation of one of the first and second controls or both of the first and second controls enables setting of the device using the display screen.

The invention claimed is: 1. An apparatus comprising: a main body; first and second controls that project from a face of the main body, the first control projecting from the face at a first direction of inclination, and the second control projecting from the face at a second direction of inclinatio
The invention claimed is: 1. An apparatus comprising: a main body; first and second controls that project from a face of the main body, the first control projecting from the face at a first direction of inclination, and the second control projecting from the face at a second direction of inclination; and a display screen disposed on the face of the main body, wherein the first control is arranged adjacent to a first side of the display screen, and the second control is arranged adjacent to a second side of the display screen, the first and second sides being arranged opposite to each other, wherein the first control is configured to move toward the second control by a first user operation from a first rest position and automatically return to the first rest position, which is away from the second control, when released from the first user operation, wherein the second control is configured to move toward the first control by a second user operation from a second rest position and automatically return to the second rest position, which is away from the first control, when released from the second user operation, wherein the first and second controls are configured to manipulate setting items of the apparatus displayable on the display screen by operating either the first or second control or both the first and second controls, wherein the first and second controls are operable independently of each other to select an item of the setting items displayable on the display screen, and the first and second controls are concurrently operable together to set the selected item. 2. The apparatus according to claim 1, wherein the main body is attachable to an arm of a user. 3. The apparatus according to claim 1, wherein the display screen displays a list of setting items to be selected to set the apparatus, the first control is operable to shift a focus on the setting items in one direction of the list for selection, and the second control is operable to shift a focus on the setting items in another direction of the list for selection. 4. The apparatus according to claim 1, further comprising a tone generator for generating tones of a music piece, wherein the first and second controls are operated to select and set the music piece in the tone generator. 5. The apparatus according to claim 1, further comprising a third control disposed on the face of the main body in the vicinity of one of the first or second control in opposed relation to one of the first or second side of the display screen relative to the one of the first or second control. 6. The apparatus according to claim 5, wherein the third control is mounted on the face of the main body in the form of a push button. 7. The apparatus according to claim 5, further comprising a support pad disposed in the vicinity of the one of the first or second control in opposed relation to the one of the first or second side of the display screen relative to the one of the first or second control, the support pad being arranged on the face of the main body and configured to support a finger that operates the one of the first or second control. 8. The apparatus according to claim 7, wherein the third control and the support pad are arranged adjacently with each other at the same height from the face of the main body. 9. The apparatus according to claim 5, wherein the one of the first or second controls is configured to be operable by a thumb of the user, and the third control is also configured to be operable by the thumb of the user. 10. The apparatus according to claim 1, wherein the first and second controls are spaced apart from each other at a span in the order of 20 mm through 50 mm to enable the first and second controls to be operable concurrently with a thumb and an index finger of the user. 11. The apparatus according to claim 10, wherein the display screen displays a cursor for use in setting the apparatus, the cursor being movable on the display screen in association with the operation of the first and second controls by the thumb and index finger of the user.
