Slits 419 a, as shown in FIGS. 6B, 6C, and 6D, which support the sliding movement of the battery locking unit 440, are provided on one side of the battery port 413.
The door member 420 comprises a hinge 421 by which the support pin 422 is attached to one side of the door. Also, a locking hole 423 is formed on the second part of the door member 420, which locks the other side of the door member 420 to the door locking unit 430. Additionally, on the outer surface adjacent to the second side of the door member 420, a hole, indent or recess 425 is formed so that a user can easily operate the door locking unit 430 with his or her finger. A door member 420 with this kind of composition is divided lengthwise into a first section 401 and a second section 402. The first section 401 protrudes further in the direction towards which the door member 420 opens than the second section. That is, the first section 401 of the door member 420 has roughly the same height as the outside of the surrounding first and second bodies 100 and 200, and the second section 402 is indented, stepped and/or recessed more relative to the first and second bodies 100 and 200.
Consequently, when the first and second bodies 100 and 200 move to the first position, the second section 402 moves to a position on the inside of the door cover 201 of the second body 200, and can be concealed from view.
A door member 420 having this exemplary structure can be made of plastic or metal, but is not limited thereto. It is desirable that it be made of aluminum alloy, which is both lightweight and strong. Also, the first section 401 and the second section 402 can have the same thickness, but they can have a stepped form provided by curving at the boundary area, and can have different thicknesses.
Moreover, the door member 420 can be kept closed by the door locking unit 430, and can be made to automatically open when the door locking unit 430 is unlocked. In order that the door locking unit 430 may be opened automatically, a spring, such as a torsion spring 426 can be installed on the support pin 422. While the torsion spring 426 is compressed, one end is attached to the door frame 410, and the other end is attached to the door member 420. The torsion spring 426 is compressed when the door member 420 is closed. When the door locking unit 430 is unlocked, the door member 420 can automatically open to roughly 900 relative to the door frame 410 due to the potential energy of the torsion spring 426.
The door locking unit 430 comprises a locking knob 431, a pressurized spring 433 and a support bracket 435. The locking knob 431 is movably accommodated on the accommodating unit 416 on the door frame 410. A locking projection 431 a is disposed on the locking knob 431, and is attached by a lock to the locking knob 431. Projections 431 b are disposed on the outside surface of the locking knob 431 to prevent sliding. A guide rib 431 c is also formed on both sides of the locking knob 431 to guide the movement of the locking knob 431 from the accommodating unit 416, and a support pole 431 d which supports the pressurized spring 433 protrudes from the top of the locking knob 431.
The pressurized spring 433 is installed between the locking knob 431 and the support bracket 435, and provides pressure in order to keep the door locking unit 430 locked by pressing the locking knob 431 against the door member 420.
The support bracket 435 is attached to the second long beam 418 of the door frame 410 in order to prevent the locking knob 431 and the pressure spring 433 becoming removed from the accommodation unit 416. This support bracket 435 comprises fastening holes 435 a into which the fused bosses 416 a on the door frame 410 are inserted, and a guide hole 435 b through which the support pole 431 d is guided. If the fused bosses 416 a are inserted into the fastening holes 435 a, the support bracket 435 can be fixed to the door frame 410 by heating the fused bosses 416 a and fusing the fused bosses 416 a onto the outside of the support bracket 435.
The door unit 400 further comprises the battery locking unit 440 which prevents the battery 500 inserted in the battery compartment 303 from falling out through the battery port 413 when the door member 410 is open.
The battery locking unit 440 as described above rotates to one side of the battery port 413. Additionally the battery locking unit 440 remains covered by the door member 420, and is installed so as to be able to move only if the door member 420 is open. This kind of battery locking unit 440, as shown in FIGS. 5D, 6B, 6C and 6D, comprises a battery locking knob 441, an operating member 442, a pressurized spring 443, and a support part 445.
The battery locking knob 441 is installed so as to be externally visible when the door member 420 is opened. The battery locking knob 441 comprises a slide unit 441 a and a locking head unit 441 b. Fusing projections 441 c protrude from the rear of the slide unit 441 a. The fusing projections 441 c are inserted and fused in fusing holes 442 a, which are formed on the operating member 442, and are placed between the slits 419 a formed by the battery locking knob 441 and the operating member 442 on the door frame 410, and are attached at predetermined intervals on the door frame 410. Additionally, the fusing projections 441 c are guided along the slits 419 a, and can thereby move in a sliding motion between the position in which the battery locking knob 441 and the operating member 442 cover the battery entrance 413, and the position in which the battery entrance 413 is uncovered.
The locking head unit 441 b is enlarged at one end of the slide unit 441 a, and the enlarged section, as shown in FIG. 6C, covers the edge of the battery port 413. Additionally, a cam face 441 d is formed on the locking head unit 441 b. As the cam face 441 d has an inclined surface, the locking head part 441 b is able to be removed from the battery port 413 despite being pushed in by the edge of the battery 500 which is inserted through the battery port 413. Also, the enlarged locking head unit 441 b forms a stepped profile with the slide unit 441 a, so that the locking head unit 441 b protrudes further outwards than the slide unit 441 a. Consequently, if the user pushes the locking head unit 441 b with his or her fingertips in direction C1, the battery locking knob 441 is removed from the battery port 413, and the battery 500 inserted in the battery compartment 303 can be removed.
The pressurized spring 443 presses the battery locking knob 441 and the operating member 442 in direction C2. Consequently, the battery locking unit 441 and the operating member 442 can be returned to the locked position, in which the battery port 413 is blocked off and the battery 500 is prevented from falling out. The pressurized spring 443 is accommodated in a spring accommodation hole 419 b on the back of the door frame 410. Also, the pressurized spring 443 is supported by the support part 445 attached in order to cover the accommodating hole 419 b on the rear of the door frame 410, and can be prevented from falling out. The support part 445 can be made of metal and is shaped like a plate. The support part 445 can be attached to the rear of the door frame 410 using glue or similar adhesive material. A plurality of fusing projections (not shown) are also formed on the rear of the door frame 410, so if the plurality of fusing projections are inserted in fusing holes 445 a and 445 b on the support part 445, the support part 445 can be fixed to the door frame 410 by being fused by the fusing projections.
The battery locking unit 440 is disposed on the door unit 400 as described above, but because it is installed so as to be concealed by the door member 420, a separate space for installation is not required. Further, since the battery locking unit 440 is not externally visible, the battery 500 can be prevented from falling out while the camera is being used or handled. Also, as the battery locking unit 440 is not externally visible, the external appearance of the camera can be improved.
The first section 401 and the second section 402 of the door member 420 in the door unit 400 as described above are formed with a stepped profile on the outside. Therefore, if the first and second bodies 100 and 200 move to the second position, a gap G arises between the first body 100 and the door member 420 which is as deep as the step of the second section 402 is indented relative to the first section, as shown in FIG. 7A, while the second section, that is, the originally-concealed section is exposed. In other words, if the door cover unit 201 is disposed on a surface roughly level with the first section 401 of the door member 420, a gap G arises if the door cover unit is removed from the second section 402 due to having a structure which covers the second section 402 with the door cover section. If a fixed component is installed so as to cover gap G, which is necessary to expand the operating space of the holding unit 203 of the second body 200, it becomes impossible to move the holding unit 203. As a result, it is difficult to achieve the sliding movement of the first and second bodies 100 and 200. By contrast, the second long beam 418 (referring to FIG. 6B) of the door frame is attached adhesively to the inside of the first body 100, so a gap does not arise on the side of the second long beam 418. Moreover, an externally visible gap does not arise at the boundary between the first and second bodies 100 and 200, since extension ribs 107 and 207 extend the outer casing of the first and second bodies 100 and 200, respectively, so as to overlap each other.
However, dust or foreign bodies can enter through the gap G which arises in the manner described above. Further, taking deficiencies in the external composition into consideration, exemplary embodiments of the present invention can further comprise the curtain unit 600 which covers the gap G. FIG. 7A is a drawing illustrating an exemplary state in which the curtain unit 600 described below is omitted.
The curtain unit 600, as shown in FIGS. 6A, 6B, 7B and 7C, comprises a curtain member 610 and a curtain spring 620.
The curtain member 610 is slidably installed between the first body 100 and the door unit 400. To be more specific, the curtain member 610 is installed so as to slide back and forth on a predetermined path along the first long beam 417 of the door frame 410.
The stopper 417 a disposed on the first long beam 417 is inserted into the curtain member 610, whereby the curtain member 610 is guided in its sliding movement. The curtain member 610 comprises a guide slit 611 which limits the sliding movement of the curtain member 610. The curtain member 610 also comprises a guide rod 612, which movably supports the curtain spring 620, a curtain unit 613 and a guide rib 614. The guide rod 612 has a predetermined length, and is inserted in a guide hole 417 d formed on the door frame 410 if the curtain spring 620 is inserted in the guide rod 612. When the curtain member 610 moves, the guide rod 612 is guided into the guide hole 417 d. Also, if the curtain spring 620 is inserted over the guide rod 612, one end of the curtain spring 620 is supported by the first stopper 417 f formed in the guide hole 417 d, and the other end of the curtain spring 620 is supported by the second stopper 615 disposed on the curtain member 610. Therefore, even if the curtain member 610 moves in direction E2 due to the force of the curtain member, if the external force is reduced, the curtain is pushed in direction E1 by the curtain spring 620 and returns to the original position.
The curtain unit 613 is disposed at a height corresponding to the height of the guide rib 417 c of the door frame 410, and the curtain unit 613 follows the guide ribs 417 c. When the curtain member 610 moves back towards E1 and is in its original position, the curtain unit 613 performs the function of substantially covering the gap G. Therefore, the length of the curtain unit 613 may be similar to or longer than the second section 402 of the door member 420.
Additionally, the guide ribs 614 are curved in a predetermined shape so as to be guided in order to be mated with the guide hole 417 e disposed on the rear of the door frame 410.
According to this exemplary structure, the curtain member 610 is interposed between the door frame 410 and the first body 100, and while sliding back and forth on top of the door frame 410, can selectively hide the gap G while changing positions according to the relative position of the first and second bodies 100 and 200. Specifically, if the first and second bodies 100 and 200 move toward the second position, the curtain member 610 is completely pushed in the direction of E1 by the spring power of the curtain spring 620, and hides the gap G described above by moving from point D1 to D2. Even if the second body 200 moves further in the direction of E1 to the extent of the distance between points D2 and D3, the curtain member 610 preferably moves only as far as point D2 at the furthest point of travel due to the stopper 417 a described above. If the first and second bodies 100 and 200 move in this manner to the second position, the second section 402 of the door member 420 is visible, and the door member 420 can open and shut. Also, the gap G is covered by the sliding movement of the curtain member 610 in the direction of E1.
In contrast, the second body 200 moves in the direction of E2 when moved to the first position, as shown in FIG. 7C. When the second body 200 moves in the direction of E2, the side 203 a of the holding unit 203 on which a button member 210 of the second body 200 is disposed, moves to position D2, and then pushes the curtain member 610 from point D2 in the direction of E2. Also, if the first and second bodies 100 and 200 as shown in FIG. 7B move completely to the first position, the curtain member 610 moves completely from point D2 to D1. In this state the curtain spring 620 is pushed in the direction of E1 due to being in a pressurized state. In this manner, when the second body 200 moves to the second position, the curtain member 610 automatically moves to point D2 due to the pressure of the curtain spring 620 and is able to cover the gap G as shown in FIG. 7A.
An exemplary method of using a camera according to an embodiment of the present invention is described in greater detail below.
FIGS. 2A and 2B are perspective views showing a state prior to movement in a camera according to an exemplary embodiment of the present invention, and FIGS. 3A and 3B show a state after movement. In order to show still images and moving images, if the push unit of the first body 100 is pushed to the left of the illustrated state shown in FIGS. 2A and 2B (the first position), the first body 100 and the second body 200 move to the second position due to the operation of the internal slide unit 300, as shown in FIGS. 3A and 3B.
Accordingly, an image can be captured while the lens 110, which was covered by the second body 200, together with the holding unit 203 of the second body 200 and the various operating buttons 210 on the holding unit 203, which were concealed by the first body 100, are made externally visible.
Moreover, the second section 402 of the door unit 400 that was concealed by the door cover unit 201 of the second body 200 is externally visible. Therefore, if the first and second bodies 100 and 200 move to the second position in this manner, and if the user properly holds the camera using the holding unit 203 while operating the various operating buttons 210 on the holding unit 203, an image can be captured. Also, as shown in FIG. 4, where the door member 420 is opened, the battery 500 and/or the recording medium can be changed. The action of opening and closing the door member 420, and the action of removing the battery 500 have been described in detail above, so further description of these actions is omitted below. Also, the action of inserting a recording media is typically comprised of actions involving inserting and/or removing the recording media while the door unit 400 is open, so further description of these actions are also omitted.
Moreover, in the state shown in FIGS. 3A and 3B, the curtain member 610 shown in FIG. 7C covers the gap G between the door unit 400 and the first body 100, by being pushed automatically to point D3 by the curtain spring 620. Therefore, even when in the second position, the outward appearance of the product is improved, and dust and foreign bodies can be prevented from entering the product.
Exemplary embodiments of the present invention can be constructed such that modes can be automatically selected in response to body movements, for example, the image capture mode can be automatically selected when the first body 100 and the second body 200 move to the second position, as described above.
Of course, other functions can be used to change the device from the image capture mode to a different mode.
If the first body 100 and the second body 200 are moved to the first position after capturing an image, and the lens 110 of the first body 100 and the operating buttons 210 of the second body are concealed, as shown in FIGS. 2A and 2B, the camera becomes more compact and portable. Also, the second section 402 of the door unit 400 becomes covered by the door cover unit 201 of the second body, and the curtain member 610 is pushed to the end 230 a of the holding unit 203 of the second body 200 as shown in FIG. 7B, and by moving the curtain member 610 towards point D1, space is made available for moving the holding unit 203.
Since functions such as Digital Media Broadcasting do not require a separate grip unit, if the camera is held appropriately, the broadcast can be viewed on the display screen and thereby illustrating an example of a mode other than the capture mode.
The present invention has been described using a number of exemplary embodiments. The terms used herein have been provided for the purpose of explanation and should not be interpreted as limiting the scope of the invention. Any number of modifications and changes can be made within the scope of the above description. Therefore, the present invention can be freely implemented within the scope of the claims to the extent that each part is not described separately.
According to embodiments of the present invention as described above, the display screen 120 on the first body can be enlarged even though the camera is compact, as the operating buttons 210 and grip unit are formed on the second body 200, which does not have the display screen.
Additionally, it is possible to provide a multi-function digital camera which is convenient to use, having both a safe grip and a large display screen.
According to embodiments of the present invention, a product can be provided which satisfies the demands of consumers.
Moreover, by providing a battery door unit which is concealed or made externally visible by the sliding movement of the first and second bodies, the door unit can be made compact. Further, by also making it possible to conceal the door unit, the design of the apparatus can also be improved.
In addition, dust and foreign bodies can be blocked from entering the gap that arises when the door unit is made externally visible due to the movement of the first and second bodies, by providing a curtain unit to cover the gap which arises in the space between the door unit and the first body in which the second body moves, and further improving the external appearance of the device.
