The Keysheet module 10 of input unit 1 includes multiple push-button units 102.The overlay structure 12 of input unit 1 includes bottom clad
120, clad 122 and layer of thermoplastic material 124 are pushed up.In the present embodiment, bottom clad 120 can be knitting layer of cloth, top packet
Coating 122 can be leather layer, and layer of thermoplastic material 124 can be foaming layer.The bottom clad 120 of overlay structure 12 covers and attaches key
Disk module 10.The layer of thermoplastic material 124 of overlay structure 12 is superimposed between bottom clad 120 and top clad 122.Overlay structure
12 layer of thermoplastic material 124 includes multiple first thermoplastic material layer segment 124a (one is only shown in Fig. 2) and the second thermoplastic
Layer material sections 124b.Second thermoplastic material layer segment 124b of layer of thermoplastic material 124 and the first thermoplastic material layer segment 124a
It is connected.Each first thermoplastic material layer segment 124a of layer of thermoplastic material 124 corresponds respectively to the region of push-button unit 102.
Second thermoplastic material layer segment 124b of layer of thermoplastic material 124 corresponds to the region other than push-button unit 102.Layer of thermoplastic material
124 each first thermoplastic material layer segment 124a has first thickness T1.Second thermoplastic material layer segment 124b has the
Two thickness T2.First thickness T1 is more than the thickness of top clad 122.First thickness T1 is 4~7 times of second thickness T2.
In the present embodiment, the layer of thermoplastic material 124 of overlay structure 12 can be formed by hot pressing with first thickness
The first thermoplastic material layer segment 124a of the T1 and second thermoplastic material layer segment 124b with second thickness T2, wherein the first heat
Moulding material layer segment 124a is the part that hot pressing amplitude is smaller or is not hot pressed, and the second thermoplastic material layer segment 124b is to be hot pressed
Part.Therefore, hot pressing amplitude is smaller or is not hot pressed and has the first thermoplastic material layer segment of larger first thickness T1
124a can correspond to the region (i.e. the surface of push-button unit 102) of push-button unit 102 and as overlay structure 12 for user
The part of pressing, and be hot pressed and with smaller second thickness T2 the second thermoplastic material layer segment 124b, can correspond to by
Region other than key unit 102 and prevent the dirty part into the gap between push-button unit 102 as overlay structure 12, on
Hot pressing amplitude is stated to indicate the first thermoplastic material layer segment 124a relative to hot pressing suffered by the second thermoplastic material layer segment 124b
The difference of degree.

Each first thermoplastic material layer segment 124a of layer of thermoplastic material 124 is superimposed on corresponding first carcass portion 120a and top
Between clad 122.Second thermoplastic material layer segment 124b of layer of thermoplastic material 124 is superimposed on the second cloth of bottom clad 120
(that is, the first carcass portion 120a of bottom clad 120 is corresponded respectively between layer segment 120b and top clad 122
The region of push-button unit 102, and the second carcass portion 120b of bottom clad 120 corresponds to the area other than push-button unit 102
Domain).Each first carcass portion 120a of bottom clad 120 has third thickness T3.Second layer of cloth portion of bottom clad 120
Divide 120b that there is the 4th thickness T4.Third thickness T3 is 1.2~1.7 times of the 4th thickness T4.
In the present embodiment, the bottom clad 120 of overlay structure 12 can equally be formed by hot pressing with third thickness
The the first carcass portion 120a and second carcass portion 120b with the 4th thickness T4 for spending T3, wherein the first carcass portion 120a
For the part that hot pressing amplitude is smaller or is not hot pressed, the second carcass portion 120b is the part being hot pressed.Therefore, hot pressing amplitude compared with
The first carcass portion 120a that is small or not being hot pressed and have larger third thickness T3, can correspond to the area of push-button unit 102
Domain (i.e. the surface of push-button unit 102) and as the part that overlay structure 12 is pressed for user, and be hot pressed and with compared with
The second carcass portion 120b of the 4th small thickness T4 can correspond to the region other than push-button unit 102 and as overlay structure
12 prevent the dirty part into the gap between push-button unit 102.
In the present embodiment, the first thickness T1 of the first thermoplastic material layer segment 124a, the first carcass portion 120a
Third thickness T3 with top clad 122 thickness summation, be the second thermoplastic material layer segment 124b second thickness T2, second
1.5~2.3 times of the summation of the 4th thickness T4 of carcass portion 120b and the thickness of top clad 122.It follows that of the invention
Overlay structure 12 only need through simple hot pressing program, you can it is specific to form structure in the region of corresponding push-button unit 102
Press section (because thickness is thicker), therefore can solve the problems, such as the required aligning accuracy faced when existing setting pressing gasket.
In addition it is noted that in order to make both top clad 122 and layer of thermoplastic material 124 have better bonding effect,
The overlay structure 12 of present embodiment includes also glue-line 126 (as shown in Figure 2), is bonded in top clad 122 and heat-stabilized wood
Between the bed of material 124, it is not easily separate to make both top clad 122 and layer of thermoplastic material 124 that can more securely bond.
Please refer to Fig. 3, Fig. 4 A and Fig. 4 B.Fig. 3 is the partial sectional view of the input unit 1 in Figure 1B.Fig. 4 A are Figure 1A
