a frame having a top opening;
a support protruding inward of said top opening and arranged along a periphery of said top opening;
a pressure sensor mounted on top of said support; and
a cover glass configured in said opening and overlying said pressure sensor;
wherein
said pressure sensor is sandwiched, in a thickness direction of said cover glass, between said cover glass and said support;
said cover glass button further comprises, in said thickness direction and within said frame,
a touch panel below said cover glass,
a display module below said touch panel, and
an electronics compartment below said display module;
the touch panel does not overlap the pressure sensor in the thickness direction;
a space is provided between said display module and said electronics compartment to make room for up and down movements of said cover glass, said touch panel and said display module relative to said electronics compartment; and
a combination of said cover glass, said touch panel and said display module is suspended above and free of contact with said electronics compartment.
12. A cover glass button as claimed in claim 11, wherein
said pressure sensor is compressible to have a reduced thickness in response to a pressure applied on said cover glass in said thickness direction, and
said pressure sensor is restorable to an original thickness thereof in response to a release of the pressure.
13. A mobile device, comprising:
a frame having a top opening;
a support protruding inward of said top opening and arranged along a periphery of said top opening;
a pressure sensor mounted on top of said support;
a transparent cover configured in said opening and overlying said pressure sensor;
a touch panel below said transparent cover;
a display module below said touch panel; and
a circuit;
wherein
a space is provided between said display module and said electronics compartment to make room for up and down movements of said cover glass, said touch panel and said display module relative to said electronics compartment;
a combination of said cover glass, said touch panel and said display module is suspended above and free of contact with said electronics compartment;
said pressure sensor is sandwiched, in a thickness direction of said transparent cover, between said transparent cover and said support, is electrically coupled to the circuit, and is configured to output a signal responsive to a pressure applied on said transparent cover in said thickness direction; and
wherein the touch panel has an outer peripheral edge spaced inwardly from an outer peripheral edge of the transparent cover, and also spaced inwardly from an inner peripheral edge of the support.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for servicing a printhead mounted on a carrier, comprising:
providing a maintenance housing defining a maintenance area and including a movable maintenance sled having a carrier engagement member;
moving the carrier from an imaging region toward the maintenance area to engage the carrier engagement member and move the maintenance sled from a rest position to one of a wiping position and a capping position, the capping position following the wiping position along a direction of travel by the carrier from the imaging region to the maintenance area;
determining whether a wiping operation is required for the servicing of the printhead; and
positioning the carrier at a first stop position directly above the capping position upon initial entrance into the maintenance area in response to the determining that a wiping operation is not required for the servicing.
2. The method of claim 1, further comprising positioning the carrier at a second stop position offset from the capping position upon initial entrance into the maintenance area in response to determining that a wiping operation is required.
3. The method of claim 1, wherein the positioning the carrier at the first stop position holds the maintenance sled at the capping position to thereby perform a capping operation on the printhead.
4. The method of claim 3, wherein when the carrier is controlled to move away from the first stop position and out of the maintenance area, the maintenance sled returns to the rest position without engaging the wiping position such that the printhead is not wiped after the capping operation.
5. The method of claim 1, further including the maintenance sled bypassing the wiping position upon leaving the capping position such that a wiping operation is not performed as the carrier moves from the maintenance area after a capping operation.
6. A method for servicing a printhead mounted on a carrier, comprising:
providing a maintenance housing defining a maintenance area and including a movable maintenance sled having a carrier engagement member;
moving the carrier from an imaging region toward the maintenance area to engage the carrier engagement member and move the maintenance sled from a rest position to one of a wiping position and a capping position, the capping position following the wiping position along a direction of travel by the carrier from the imaging region to the maintenance area; and
selectively locking the maintenance sled at the wiping position without engaging the capping position based on a stop position of the carrier upon initial entrance into the maintenance area.
7. The method of claim 6, further including determining whether a wiping operation is required for the servicing of the printhead.
8. The method of claim 6, further including returning the carrier to the imaging region without said engaging the capping position.
