As illustrated in Figs. 16 and 18, the inserting/drawing unit 100 of the camera lens module 300 of the portable communication device is provided at the second housing 20. In a housing 200 of the inserting/drawing unit 100 is mounted a camera lens module 300, which includes a cylindrical lens housing 301 for accommodating a camera lens unit 45 therein, as shown in Fig. 6. At an outer circumferential surface of the lens housing 301 of the camera lens module 300 is formed a lens opening 301b through which a picture of an outer subject is taken. The lens housing 301 of the camera lens module 300 has an open end 302 through the camera lens unit 45 is inserted into the lens housing 301. The lens housing 301 of the cameral lens module 300 is provided at the other end opposite to the open end 302 with a plurality of saw-toothed portions 303 having inclined surfaces formed along the circumference of the lens housing 301. Inside the saw-toothed portions 303 are formed engagement grooves 304, in which engaging parts 401 formed at a rotary cam 400 are engaged. Consequently, the engaging parts 401 of the rotary cam 400 are engaged in the corresponding engagement grooves 304.
The rotary cam 400 extends in the longitudinal direction of the lens housing 301. In the saw-toothed portions 303 is formed a connection protrusion 306, which extends in the longitudinal direction of the lens housing 301. To the connection protrusion 306 is connected a shaft 900 having a coupling part 901 formed at one end thereof (shown in FIG. 17). In the connection protrusion 306 is formed a screw hole 306a, through which a screw 1000 is inserted so that the connection protrusion 306 is connected with the shaft 900. In the rotary cam 400 is mounted a bush ring 600 having a rib 601 through which the coupling part 901 of the shaft 900 is inserted. Between the connection protrusion 306 of the camera lens module 300 and the bush ring 600 is provided a second spring 702, which is arranged on the shaft 900. The second spring 702 provides an elastic force, by which the inclined surfaces of the saw-toothed portions 303 of the camera lens module 300 are separated from inclined surfaces 403a formed at the latching protrusions 403 of the rotary cam 400. Thus, the camera lens module 300 is drawn out from the housing 200 while being rotated about a hinge axis A1 (shown in FIG. 8) of the camera lens module 300. On the coupling portion 901 of the shaft 900 is fitted an O-ring 800, and the rotary cam 400 is rotatably attached to the lens housing 301. The lens housing 310 and the rotary cam 400 are mounted in the housing 200.
At one end of the housing 200 is provided a deco part 201 attached to the camera lens module 300 using at least one screw 1000. Consequently, the deco part 201 is inserted into or drawn out from the housing 200 with the camera lens module 300. The deco part 201 has at least one screw hole 201a formed at a region thereof, through which the screw 1000 is inserted. The screw 1000 is inserted into at least one screw-fixing hole 305 formed in the lens housing 301 of the camera lens module 300 through the screw hole 201a, and thus the deco part 201 is attached to the lens housing 301. At the outer surface of the deco part 210 is provided a deco cap 201b for protecting the deco part 201. The deco cap 201 has at least one insertion groove 201c in which the head of the screw 1000 is placed when the screw 100 is inserted through the screw hole 201a of the deco part 201. To the other end of the housing 200 is attached a spring cap 202 for supporting a first spring 701, which is provided between the spring cap 202 and the rotary cam 400 for providing an elastic force, by which the camera lens module 300 is inserted into or drawn out from the housing 200. On the outer circumferential surface of the spring cap 202 are formed a plurality of engagement portions 202a each having a protrusion 202b formed at one end thereof. The protrusions 202b of the engagement portions 202a are engaged in engagement grooves 203 formed at the housing 200. Consequently, the spring cap 202 is attached to the housing 200 by the engagement of the engagement portions 202a in the engagement grooves 203 of the housing 200. At a central part of the spring cap 202 is formed a spring fixing protrusion 202c for fixing and supporting the first spring 701. At the central part of the bush ring 600 is formed a bush ring fixing protrusion 602. Consequently, the second spring 702 is disposed between the camera lens module 300 and the bush ring 600, and the second spring 702 is fixed to the connection protrusion 306 of the camera lens module 300 and to the bush ring fixing protrusion 602. In the housing is provided a stopper cam 500, which releasably restricts the rotation of the rotary cam 400. Thus, the camera lens module 300 can be inserted into or drawn out from the housing 200 as the camera lens module 300 and the rotary cam 400 are rotated together with each other when the camera lens module 300 is pushed, as illustrated in Fig. 7. The stopper cam 500 is supported by a latching jaw 204 formed inside the housing 202.
When the camera lens module 300 is pushed as illustrated in Figs. 8 and 9, the camera lens module 300 is drawn out from the housing 200 in the direction in which the camera lens module 300 is pushed. When the camera lens module 300 is pushed, the latching protrusions 403 of the rotary cam 400 are separated from latching jaws 501a of first guide inclined surfaces 501 of the stopper cam 500, as shown in Figs. 10 and 11. The rotary cam 400 is rotated in a direction of rotation 3, and the latching protrusions 403 of the rotary cam 400 are moved to second guide inclined surfaces 502 of the stopper cam 500 while being rotated. In the stopper cam 500 is formed first guide grooves 503 which are formed in the longitudinal direction of the stopper cam 500 for guiding the latching protrusions 403 of the rotary cam 400. Consequently, the latching protrusions 403 of the rotary cam 400 are guided using the second guide inclined surfaces 502 and moved into the first guide grooves 503 while being rotated. The latching protrusions 403 of the rotary cam 400 are inserted into the first guide grooves 503 as illustrated in Figs. 13 and 14.
The lens housing 301 is drawn out from the housing 200 in the direction in which the lens housing 301 is pushed using the elastic force of the first spring 701. Inside the stopper cam 500 are provided second guide grooves 504, which are formed in the longitudinal direction of the stopper cam 500. In the second guide grooves 504 are engaged guide protrusions 301a of the lens housing 301. The rotary cam 400 has an undercut part 402 for restricting the drawing operation of the rotary cam 400 when the lens housing 301 and the rotary cam 400 are drawn out from the housing 200, as shown in Fig. 15. Consequently, the drawing operation of the stopper cam 500 is stopped when the stopper cam 500 contacts the undercut part 402 of the rotary cam 400. At the same time, the engaging parts 401 of the rotary cam 400 are disengaged from the engagement grooves 304 of the lens housing 301 using the elastic force of the second spring 702, as illustrated in Figs. 19 and 20. Consequently, the lens housing 301 can be rotated about the hinge axis A1 of the camera lens module 300, as illustrated in Fig. 18. Under this condition, a picture of a subject can be taken using the camera lens unit 45 of the camera lens module 300. When the camera lens module 300 is inserted again into the housing 200 as illustrated in Figs. 16 and 17, the engaging parts 401 of the rotary cam 400 are engaged into the engagement grooves 304 of the lens housing 301. The lens housing 301 and the rotary cam 400 are inserted into the housing 200. The guide protrusions 301a of the lens housing 301 are guided into the second guide grooves 504 of the stopper cam 500. The latching protrusions 403 of the rotary cam 400 are separated from the first guide grooves 503 of the stopper cam 500. As illustrated in Fig. 9, the latching protrusions 403 of the rotary cam 400 are moved to the first guide inclined surfaces 501 of the stopper cam 500 as the rotary cam 400 is moved in the direction 3 while being rotated. The latching protrusions 403 of the rotary cam 400 are guided to the latching jaws 501a of first guide inclined surfaces 501 of the stopper cam 500 along the first guide inclined surfaces 501 of the stopper cam 500. The latching protrusions 403 of the rotary cam 400 contact the latching jaws 501a, and the lens housing 301 remains inserted in the stopper cam 500.
