The base seat is elongated in a front-rear direction, and includes a bottom face portion and an extension face portion surrounding and extending upwardly from the bottom face portion, and having spaced apart first and second lateral sections. The housing surrounds the base seat, extends upwardly from the extension face portion, and includes an operating portion extending upwardly from the first lateral section and having front, rear, upper, and lower pressing regions. The lateral pressure sensing unit is located in the inner space, is adjacent to the front, rear, upper and lower pressing regions, and is triggered upon operation on the operating portion. ## Claims ### Claim 1 A mouse device adapted to be operated by a thumb, an index finger, and a middle finger of a user, said mouse device comprising: a base unit that has a base seat being elongated in a front-rear direction, and including a bottom face portion, an extension face portion that surrounds said bottom face portion, that extends upwardly from said bottom face portion in an up-down direction perpendicular to the front-rear direction, and that has a first lateral section and a second lateral section spaced apart from each other in a left-right direction perpendicular to the front-rear direction and the up-down direction, and a housing surrounding said base seat, extending upwardly from said extension face portion of said base seat in the up-down direction, and including an operating portion that is adapted for operation by the thumb, that extends upwardly from said first lateral section, and that has a main region, a front pressing region, a rear pressing region disposed behind said front pressing region, an upper pressing region disposed above said front pressing region and said rear pressing region, and a lower pressing region disposed below said front pressing region, said rear pressing region, and said upper pressing region, said front pressing region, said rear pressing region, said upper pressing region, and said lower pressing region being disposed on said main region, and a palm supporting portion that cooperates with said operating portion to surround said base, and an inner space cooperatively defined by said base seat and said housing; a main button unit that includes a first mouse button and a second mouse button disposed on said base unit, and being respectively adapted for operation by the index finger and the middle finger; and a lateral pressure sensing unit that is located in said inner space, that is adjacent to said front pressing region, said rear pressing region, said upper pressing region and said lower pressing region, and that is configured to be triggered upon operation by the thumb on said operating portion. ### Claim 2 (depends on 1) The mouse device as claimed in claim 1, wherein said lateral pressure sensing unit includes: a front pressure sensor corresponding in position to said front pressing region; a rear pressure sensor corresponding in position to said rear pressing region; an upper pressure sensor corresponding in position to said upper pressing region; a lower pressure sensor corresponding in position to said lower pressing region; and a lateral circuit board electrically connected to said front pressure detecting sensor, said rear pressure detecting sensor, said upper pressure detecting sensor, and said lower pressure detecting sensor. ### Claim 3 (depends on 2) The mouse device as claimed in claim 2, wherein said lateral circuit board is a flexible printed circuit board. ### Claim 4 (depends on 1) The mouse device as claimed in claim 1, wherein: said front pressing region and said rear pressing region define a first axis extending therethrough; a first angle between a first imaginary plate that overlaps the first axis and that extends in the left-right direction and a horizontal reference plane that is normal to the up-down direction ranges from 10° to 30°; said upper pressing region and said lower pressing region define a second axis extending therethrough; and a second angle between a second imaginary plate that overlaps the second axis and that extends in the left-right direction and a vertical reference plane that is normal to the front-rear direction ranges from 10° to 30°. ### Claim 5 (depends on 1) The mouse device as claimed in claim 1, wherein: a lowest end of said front pressing region is spaced apart from said bottom face portion by a first height in the up-down direction; a top end of said operating portion is spaced apart from said bottom face portion by a second height in the up-down direction; and said second height is substantially three times said first height. ### Claim 6 (depends on 1) The mouse device as claimed in claim 1, wherein said base seat further includes a non-slip strip connected to said bottom face portion. ### Claim 7 (depends on 1) The mouse device as claimed in claim 1, wherein said operating portion is a curved surface that curves inwardly. ### Claim 8 (depends on 1) The mouse device as claimed in claim 1, wherein said front pressing region, said rear pressing region, said upper pressing region, and said lower pressing region are made of an acrylonitrile-butadiene-styrene (ABS) copolymer resin coated with a thermoplastic polyurethane (TPU). ### Claim 9 (depends on 1) The mouse device as claimed in claim 1, wherein: said front pressing region and said lower pressing region define a first axis extending therethrough; and a first angle between a first imaginary plate that overlaps the first axis and that extends in the left-right direction and a horizontal reference plane that is normal to the up-down direction ranges from 10° to 30°. ### Claim 10 (depends on 1) The mouse device as claimed in claim 1, wherein: said upper pressing region and said lower pressing region define a second axis extending therethrough; and a second angle between a second imaginary plate that overlaps the second axis and that extends in the left-right direction and a vertical reference plane that is normal to the front-rear direction ranges from 10° to 30°.
