Then, it is received by the light receiving element 42b, whereby the scrolling condition of the wheel 2〇 can be detected. The present design achieves the waterproof function by the above design because the liquid cannot penetrate the mouse between the upper case member and the lower case member 3〇 by the first waterproof ring S1. Further, with the second waterproof ring S2, the liquid does not intrude between the upper tubular portion 12 and the lower tubular portion 32, and even if the liquid is inadvertently splashed near the roller 2, the upper and lower tubular portions 12 and 32 can be removed. The space is discharged outwards. Referring to Figures 5 and 6 in the present embodiment, the upper casing assembly 1 is composed of an upper casing 11 and a pressing casing 13 assembled to the top surface of the upper casing n. The pressing housing 13 has a pair of pressing keys 32 at the front end thereof and an opening 134 formed between the s-to-press keys 132. A pressing protrusion 322 extends downward from a bottom surface of each of the pressing keys 132. The front end of the pressing housing 13 is formed with a nip 133' which is elastically pressed between the pair of pressing keys 32.

The pressing protrusions 1322 of the pair of pressing keys 32 are correspondingly abutted against the top surface of the pair of pads, wherein the pair of spacers u2 can be covered by the pair of through holes 110 by various conventional fastening means. The upper housing U of the present embodiment also has a pair. The resilient arms 114 extend downwardly from the edges of the pair of through holes 110 and abut the pair of microswitches 44 of the circuit board 40. Referring to FIG. 7', when the pressing button 132 of the pressing housing 13 is pressed downward, the pressing protrusion 1322 touches down the spacer 112 of the upper casing n while the elastic arm 114 of the upper casing 11 is pushed downward to touch Touch the micro switch 44 of the circuit board 4〇. There is no gap between the pressing button 132 of the embodiment and the micro switch 44 of the circuit board 4, so that liquid can invade the inside of the mouse, even if liquid is accidentally splashed between the pressing housing 13 and the upper housing 11, the liquid system borrows Blocked by the spacer n2' outside the upper casing 11, flowing out along the top surface of the upper casing u, and re-engaging the first waterproof ring si between the upper casing 11 and the lower casing assembly 30, It is also possible to prevent liquid from penetrating into the interior of the mouse from the edge of the upper casing n. Referring to FIG. 6, the pressing housing 13 has a plurality of hooks 136 extending downward from the bottom surface thereof. Referring to FIG. 5, the top surface of the upper housing 1] is formed. A plurality of non-penetrating card slots Ιό corresponding to the hooks 136, whereby the pressing housing 13 can be engaged with the upper housing 1].
