'Sanda number: TW3451PA - A variety of input devices such as touch screens. However, not every 'input device' can meet the user's habits and needs. For example, when the surface to be displayed is beyond the range that the screen can display, it needs to be applied to the scrolling bar to scroll the surface to present the data in its entirety. The general operation mode requires the user to take time and effort to drag back and forth with the mouse, or repeatedly press the arrow keys of the keyboard. On the one hand, these actions add to the damage of mechanical or mechanical components in the input device, and on the other hand increase the burden on the user and increase the inconvenience in use.

The photosensitive member 30 further includes a first photosensitive member 31 and a second photosensitive member 32. The first photosensitive element 31 is disposed on the substrate 10 at a position corresponding to the first sensing region 13a, and the second photosensitive member 32 is disposed on the substrate 10 at a position corresponding to the second sensing region 13b. The input device 100 of this embodiment further includes a support structure 70. As shown in Fig. 1, the support structure 70 is disposed on the substrate 10, preferably attached. It is placed on both sides of the photosensitive element 30, and avoids the light illuminating the substrate 10 to a more precise range. It is said that the range in which the light ray 53 is irradiated to the photosensitive element 30 is avoided. The support structure 70 supports the roller assembly 40 above the substrate 10. In one embodiment, the roller assembly 40 has two lugs 41 that are located on either side of the roller assembly 40. The support structure 70 has two card slots 71 which are respectively abutted against the inner wall 71a of the card slot 71 by an elastic member 73(1) and 73(2).

• Sanda number: TW3451PA ‘14, as shown in Figure 1. At this time, the photosensitive element 30 does not sense the light 53, and does not output an electrical signal. When the user applies force to the roller assembly 40, • causes the roller assembly 40 to compress the elastic member 73(1) or 73(2) by the lugs 41 on one side, the roller assembly 40 is tilted. Please refer to FIG. 3A and FIG. 3B at the same time. FIG. 3A is a schematic view showing the roller assembly of FIG. 2 inclined at a predetermined angle in the first direction; FIG. 3B is a diagram showing the roller assembly of FIG. 2 tilting at a predetermined angle along the second direction.

The side is rolled in the other direction. In this embodiment, the width of the non-sensing area 14 is substantially equal to the width of the light spot 53a, that is, as long as the roller assembly 40 is slightly tilted in the first direction D1 or the second direction D2, the photosensitive element 30 can be detected. Light 53 was detected. As the tilt angle of the roller assembly 40 increases, the amount of light 53 detected by the photosensitive member 30 also increases until the entire spot 53a falls into the photosensitive region 12. Therefore, the photosensitive element 30 can be configured to output an electrical signal to the processing unit 80 after the amount of the detected light 53 reaches a certain value, 9 1352920
