## Abstract

A user interface device including a touchpad behind a protection plate, behind which the touchpad can freely shift with respect to the protection plate, along an axis perpendicular to the protection plate.

## Claims

### Claim 1

A user interface device comprising:
a protection plate; and
a touchpad behind the protection plate, wherein the touchpad can freely shift with respect to the protection plate along an axis perpendicular to the protection plate.

### Claim 2 (depends on 1)

The device of claim 1, wherein a resilient return maintains the touchpad against the protection plate.

### Claim 3 (depends on 2)

The device of claim 2, wherein the resilient return comprises at least one spring.

### Claim 4 (depends on 3)

The device of claim 3, wherein the spring is a helical metal spring.

### Claim 5 (depends on 1)

The device of claim 1, further comprising:
a package; and
a frame attached to the package,
wherein the protection plate is maintained by the frame, and
wherein the touchpad can freely shift with respect to the package.

### Claim 6 (depends on 1)

The device of claim 1, wherein the protection plate is a transparent glass.

### Claim 7 (depends on 1)

The device of claim 1, further comprising a support, wherein the touchpad is attached to the support and can freely shift perpendicularly to the protection plate.

### Claim 8 (depends on 7)

The device of claim 7, wherein the support is assembled to freely shift along a plurality of slides arranged perpendicular to the protection plate.

### Claim 9 (depends on 1)

The device of claim 1, wherein the touchpad is a projected capacitive touchpad.

### Claim 10 (depends on 1)

The device of claim 1, wherein the device is configured to process transport tickets.

### Claim 11 (depends on 2)

The device of claim 2, further comprising:
a package; and
a frame attached to the package,
wherein the protection plate is maintained by the frame, and
wherein the touchpad can freely shift with respect to the package.

### Claim 12 (depends on 3)

The device of claim 3, further comprising:
a package; and
a frame attached to the package,
wherein the protection plate is maintained by the frame, and
wherein the touchpad can freely shift with respect to the package.

### Claim 13 (depends on 4)

The device of claim 4, further comprising:
a package; and
a frame attached to the package,
wherein the protection plate is maintained by the frame, and
wherein the touchpad can freely shift with respect to the package.
