Display-positioning mechanism
View Patent ↗A display-positioning mechanism capable of reliably implementing, with a small number of components, relative positioning of a display aperture portion and a display. Gaps are formed between a screw head and a mounting portion and between a baseplate and an LCD unit. Hence, the LCD unit is movable within a predetermined range relative to the baseplate. When a second casing body is attached to a first casing body, from the LCD unit side, the LCD unit is accommodated at an inner side of a positioning portion, while a fitting protrusion frame of the first casing body is fitted into a fitting recess frame of the second casing body. The LCD unit is positioned in a display aperture portion by the positioning portion, and an upper face portion disposed at the inner side of the positioning portion presses against the LCD unit, which is tightly contacted with the baseplate and fixed.
1. A display-positioning mechanism for positioning a display inside a casing which is structured by a first casing body and a second casing body, which is attached to the first casing body, the mechanism comprising:
a base which is fixed in the casing;
a provisional fixing member which attaches the display to the base such that the display is movable within a predetermined range relative to the base;
a positioning portion for restricting movement of the display at a time of attachment of the second casing body to the first casing body, and retaining the display at a predetermined position, and
a resilient member for pushing the display against an inner face of the second casing body;
wherein the display comprises a frame portion, and the resilient member is formed integrally with the frame portion,
wherein the base is fixed to the first casing body, and
wherein the positioning portion is provided at the second casing body.
2. The display-positioning mechanism of claim 1 , wherein the provisional fixing member comprises a stepped screw.
3. The display-positioning mechanism of claim 1 , wherein the positioning portion comprises a plurality of projections capable of restricting movement of the display.
4. The display-positioning mechanism of claim 3 , wherein the projections are capable of restricting movement of the display in all directions.
5. The display-positioning mechanism of claim 3 , wherein the projections are formed integrally with the second casing body.
6. The display-positioning mechanism of claim 1 , wherein the base comprises a reference potential terminal for maintaining a reference potential of the display.
7. The display-positioning mechanism of claim 6 , further comprising, separately from the resilient member, a reference potential-receiving terminal which is capable of electrically contacting with the reference potential terminal for maintaining the reference potential of the display.
8. A display-positioning mechanism for positioning a display inside a casing which is structured by a first casing body and a second casing body, which is attached to the first casing body, the mechanism comprising:
a base which is fixed in the casing;
a provisional fixing member which attaches the display to the base such that the display is movable within a predetermined range relative to the base;
a positioning portion for restricting movement of the display at a time of attachment of the second casing body to the first casing body, and retaining the display at a predetermined position; and
a resilient member for pushing the display against an inner face of the second casing body,
wherein the base comprises a reference potential terminal for maintaining a reference potential of the display, and
wherein the resilient member comprises functionality as a reference potential-receiving terminal which is capable of electrically contacting with the reference potential terminal for maintaining the reference potential of the display.
9. A display-positioning mechanism for positioning a display inside a casing which is structured by a first casing body and a second casing body in which a display aperture portion is formed, and which is attached to the first casing body, the mechanism comprising:
a base which is fixed to the first casing body;
a provisional fixing member which attaches the display to the base such that the display is movable within a predetermined range relative to the base;
a positioning portion which is provided at the second casing body for restricting movement of the display at a time of attachment of the second casing body to the first casing body, and retaining the display at an accurate position relative to the display aperture portion, and
a resilient member for pushing the display against an inner face of the second casing body;
wherein the display comprises a frame portion, and the resilient member is formed integrally with the frame portion.
10. The display-positioning mechanism of claim 9 , wherein the positioning portion comprises a plurality of projections capable of restricting movement of the display.
11. The display-positioning mechanism of claim 10 , wherein the projections are capable of restricting movement of the display in all directions.
12. The display-positioning mechanism of claim 11 , wherein the projections are formed integrally with the second casing body.
13. The display-positioning mechanism of claim 10 , wherein the projections are formed integrally with the second casing body.
14. The display-positioning mechanism of claim 9 , wherein the projections are formed integrally with the second casing body.
