Description

  The present invention relates to an electronic device according to an accessory storage portion of the electronic device.

  2. Description of the Related Art Conventionally, a mechanism for storing an electrical accessory such as a battery or a card in an electronic device such as a camera has been used to detect the opening / closing of a lid of a storage unit and stop the circuit of the device in advance. This is because if the accessory is attached or detached while the camera is in operation, the captured image may be lost or the memory card or the camera's internal circuitry may be electrically damaged. It is. For example, as seen in Patent Document 1, a detection switch is exposed in an accessory storage port, and this is directly pressed by opening and closing the lid, thereby transmitting the open / closed state of the lid to the device circuit.

  As another example, FIG. 7 shows a conventional example of a camera that can store a rechargeable battery and a memory card. In this case, the photographer forms a hollow inside the body of the grip portion that holds the camera body with the right hand when photographing with the camera, and is provided with a connection terminal to function as a battery housing portion and a memory card housing portion.

  Reference numeral 101 denotes a camera body, and 101a denotes a grip portion. Reference numeral 102 denotes a lid unit that closes the entrance of the accessory. The lid unit 102 has a substantially rectangular shape when viewed from the lower surface side of the camera body 101. The lid unit 102 is slid in the rear surface direction (Z direction) of the camera 101 and then released. It is a method of rotating and opening. When opened, a rechargeable battery 103 and a memory card 104 for recording a photographed image can be inserted therein.

  FIG. 8 shows an exploded view with the lid unit 10 opened. Reference numeral 105 denotes a front cover of the camera body 101, 106 denotes a rear cover, 107 denotes a chassis, 108 denotes a holder, and 109 denotes a bearing. Other built-in members are omitted here.

  Next, the lid unit 102 will be described with reference to FIG. 9. Reference numeral 110 denotes a lid, which is formed of a molding material, has holding portions 110a and 110b on the inside, and a lid plate 111 is fitted therein to perform a sliding operation in the Z direction. Install as possible. Reference numerals 110a and 110b denote bearing holes, into which the shaft 112 is inserted, and the lid unit 102 can be rotated around the shaft 112. Reference numerals 110c and 110d denote locking portions which are locked to the claw portions 108a and 108b provided on the holder 108.

  Next, 113 is a pressing plate, which is fastened to the lid 110 with screws 114 and 115, slides in the Z direction integrally with the lid 110, and abuts the contact portions 113a and 113b to the lid plate 111 to bring the lid 110 into contact. Limit the range of sliding motion. In addition, the pressing plate 113 is provided with a click projection 113c, and by engaging this with the click hole 111c of the lid plate 111, a click feeling can be obtained during the sliding operation.

  Next, the structure of the camera body 101 will be described with reference to FIG. The bearing 109 is attached to the chassis 107 and fixed with screws 116 to 119.

  Next, 109a is a bearing hole for mounting the lid unit 102. Here, the shaft 112 is passed through the bearing holes 111a and 111b of the lid plate 111, and the other is passed through the bearing portion 107a of the chassis 107 so that the lid unit 102 is rotatable. Install in a proper condition.

Next, 120 is a detection switch. The detection switch 120 is mounted on a circuit board 121 attached to the chassis 107. A detection lever 122 is attached to a lever shaft 109b formed on the bearing 109. The detection portion 122a is exposed at a position where it hits the lid 110, and the tip end portion 122b is configured to push the detection switch. When the lid is opened and closed, the lid unit 102 is rotated, whereby the detection unit 122a is pushed by the lid 110, and the movement is transmitted from the tip end part 122b to the detection switch to determine whether or not the lid unit 102 is open.
Japanese Patent Laid-Open No. 2001-21979 (page 9, FIG. 6)

  The conventional method requires a large switch mechanism and is not compatible with recent miniaturization of cameras. Further, many members are interposed between the attachment of the detection switch 120 and the attachment of the lid 110, and the positional accuracy between the two is likely to vary, and the detection switch 120 does not operate even when the lid 110 is opened or closed. Even if the lid 110 is not opened and closed, the detection switch 120 malfunctions only by pushing the outer surface.

  Further, in the method of detecting the rotation operation after the lid 110 is linearly operated, the detection timing of the lid opening / closing operation is late, so the time for stopping the protection circuit is small, and the battery 103 or the memory card 104 is not yet stopped before the circuit is stopped. There is a risk that the circuit may be taken out, and there is a load that must be performed to speed up the difficult circuit stop to prevent it.

  In addition, in order to improve the operability of the lid 110, it is necessary to secure a sufficient gap at the boundary with the camera body 101, which causes intrusion of dust, foreign matter, etc., and causes deterioration in appearance quality. It was with me.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to examples.

  FIG. 1 shows an external view of an electronic apparatus (camera) according to an embodiment of the present invention. Reference numeral 1 denotes a camera body, and 2 denotes a lid unit that closes the entrance of the accessory storage section. 3 is a battery similar to the conventional example, and 4 is a memory card.

  As shown in FIG. 2, the lid unit 2 has a mounting portion 5a inside a lid 5 formed of a mold material, which is passed through a through hole 6a of a lid plate 6 made of stainless steel sheet, and is further made of stainless steel from the inside. A fixing plate 7 made of sheet metal is covered, screws 8 and 9 are passed through screw holes 7a and 7b, and fixed to lower holes 5b and 5c by fastening. At this time, since the through hole 6a has a rectangular shape, the lid 5 and the fixing plate 7 can be linearly moved integrally along the longitudinal direction. The lid 5 is provided with a click groove 5d, and a click spring 6b is provided on the lid plate 6 so as to slide there. 3A and 3B, the sliding portion 6c at the tip of the click spring 6b slides between the recesses 5e and 5f of the click groove 5d as the lid 5 moves linearly. The lid 5 is urged to a closed position (FIG. 3A) and an open position (FIG. 3B).

  Next, the structure on the camera body 1 side will be described with reference to FIG. Reference numeral 10 denotes a bearing, which is made of a metal material made of zinc die cast so as to ensure sufficient strength as a bearing. The positioning dowels 10a and 10b are fitted into the positioning holes 11a and 11b of the chassis 11 to accurately position the screw. Screws 12 and 13 are passed through the holes 10c and 10d, and are fastened and fixed to the pilot holes 11c and 11d.

  Next, 6d and 6e are bearing holes to which the lid unit 2 is attached. The shaft 14 is passed through the bearing holes 6d and 6e of the lid plate 6, and the lid unit 2 is attached while being rotatable in the Y direction. Reference numeral 10g denotes a stopper portion that, when the lid 5 moves linearly in the closing direction, hits the lid 5 and stops further movement. A biasing spring 15 is attached together with the lid unit 2 and constantly biases the rotation of the lid unit 2 in the opening direction. When the lid unit 2 rotates to the end in the opening direction, the stopper portion 6f of the lid plate 6 hits the stopper portion 10g of the bearing 10 and stops its rotation.

  Next, reference numeral 16 denotes a detection switch, which detects whether or not the lid 5 has been pressed to determine whether the lid unit 2 is opened or closed, and the internal circuit of the camera body 1 so that accessories such as the battery 3 and the memory card 4 can be attached and detached. Is for stopping. The detection switch 16 is attached to positioning dowels 10h and 10i provided on the bearing 10, and fixed to the pilot hole 10j with screws 17. For this reason, the detection switch 16 can maintain high positional accuracy with respect to the lid unit 2 and can accurately detect the linear movement of the lid unit 2.

  10k is a tripod screw hole. This is used when the camera body 1 is mounted and fixed on a tripod. By providing the camera body 1 integrally with the bearing 10, the number of parts can be reduced and the space can be used effectively, and the bearing 10 is made of a metal material made of zinc die casting. The strength required for fixing the camera body 1 can be sufficiently secured by using the configuration.

  Next, 18a and 18b are hook claws provided on the holder 18, and when the lid unit 2 is linearly moved from the closed position to the open position as described above, the engagement with the hook claws 5g and 5h provided on the lid 5 is removed. It has become.

  Next, when the camera body 1 is viewed from below as shown in FIG. 5, the lid 5 has a substantially rectangular shape, but the lid side surfaces 5 i and 5 j of the lid 5, the lid mounting portion side surface 1 a of the camera body 1, and The boundary line with 1b is inclined to predetermined angles α and β with respect to the X direction, and when the lid 5 is linearly moved in the X direction, the gap between the lid side surfaces 5i and 5j and the lid mounting portion side surfaces 1a and 1b Is spreading.

  Further, when viewed from the side surface direction of the camera body 1 as shown in FIG. 6, the boundary lines between the lid side surfaces 5i and 5j and the lid mounting portion side surfaces 1a and 1b are formed to be inclined at predetermined angles γ and δ with respect to the Y direction. When the lid 5 is closed, the lid side surfaces 5i and 5j are closed so as to approach the lid attaching portion side surfaces 1a and 1b along predetermined angles γ and δ.

  The electronic apparatus (camera) according to the embodiment of the present invention is configured as described above.

  Next, the lid unit 2 opening / closing operation of the electronic apparatus (camera) will be described.

  The user holds the camera body 1 upside down so that the lid 5 can be seen as shown in FIG. In this state, the boundary lines between the lid side surfaces 5i and 5j of the lid 5 and the lid mounting portion side surfaces 1a and 1b of the camera body 1 are almost in close contact with each other. It is easy to prevent entry of foreign objects.

  Since the sliding portion 6c at the tip of the click spring 6b is engaged with the recess 5e of the click groove 5d, the lid 5 is biased toward the closed position and is in a sealed state. In order to open this, first, the lid 5 is linearly moved in the X direction by hand from the closed position to the open position.

  At this time, as described above, the boundary lines between the lid side surfaces 5i and 5j of the lid 5 and the lid mounting portion side surfaces 1a and 1b of the camera body 1 are formed to be inclined at predetermined angles α and β with respect to the X direction. Therefore, since the gap between the lid side surfaces 5i and 5j and the lid attachment portion side surfaces 1a and 1b is widened along with the linear movement, the operation of opening the lid 5 has a sufficient gap and is easy to operate.

  Then, by this linear operation, it is determined that the lid unit 2 has been opened in order to shift from the state in which the detection switch 16 is pushed to the lid 5 to the state in which the detection switch 16 is not pushed, and the image data stored in the memory card 4 is lost. The internal circuit of the camera body 1 can be stopped so that accessories such as the battery 3 and the memory card 4 can be attached and detached without electrically damaging the 4 itself. In addition, since the circuit can be stopped at the stage of the linear operation before the cover 5 is rotated and completely opened, the battery 3 and the memory card 4 can be taken in and out more safely.

  Next, when the lid 5 is completely linearly moved from the closed position to the open position, the mounting portion 5a of the lid 5 reaches the end of the rectangular through hole 6a of the lid plate 6 in the opening direction, and the linear movement is stopped at that position. Is done.

  At this time, as shown in FIG. 3B, the sliding portion 6c at the tip of the click spring 6b is engaged with the recess 5f of the click groove 5d, and the lid 5 is urged toward the open position. Then, the terminal state in the opening direction is maintained.

  Further, when the hand is released, the lid unit 2 rotates in the opening direction by the urging force of the urging spring 15, and when the lid unit 2 rotates to the end in the opening direction, the stopper portion 6f of the lid plate 6 hits the stopper portion 10g of the bearing 10. The rotation is stopped.

  Therefore, when opening the lid, simply move the lid linearly and release it, and the lid will automatically rotate, so you can easily open the lid and keep it open as it is, Battery 3 and memory card 4 can be easily replaced.

  Further, even if a force is applied in the direction in which the lid unit 2 is further opened in this state, the force is received by the stopper portions 10g and 6f, so that other portions can be prevented from being deformed or damaged.

  Subsequently, when closing the lid unit 2, the user closes the lid unit 2 by rotating the lid unit 2 in the Y direction against the biasing of the biasing spring 15. At this time, as shown in FIG. 6, in the side surface direction of the camera body 1, the boundary lines between the lid side surfaces 5i and 5j and the lid mounting portion side surfaces 1a and 1b are at predetermined angles γ and δ with respect to the closing direction. Since it is formed to be inclined, the lid side surfaces 5i and 5j can be smoothly closed along the predetermined angles γ and δ so as to approach the lid attaching portion side surfaces 1a and 1b even if there is a backlash in the rotating shaft. The gap between the main body 1 and the lid 5 is minimized to improve the appearance quality, and it is easy to prevent entry of dust and foreign matter.

  When the lid 5 is linearly moved in the X direction as it is, the lid side surfaces 5i and 5j of the lid 5 and the lid attachment side surfaces 1a and 1b of the camera body 1 are formed to be inclined at predetermined angles α and β with respect to the X direction. Therefore, the lid side surfaces 5i and 5j can be smoothly sealed along the predetermined angles α and β, and the gap between the camera body 1 and the lid 5 can be minimized to improve the appearance quality. It is easy to prevent entry of dust and foreign matter.

  Further, as shown in FIG. 3A, the sliding portion 6c at the tip of the click spring 6b is engaged with the recess 5e of the click groove 5d, and the lid 5 is urged toward the closed position. At this time, the rectangular shape of the through hole 6a is set so that the lid 5 contacts the stopper portion 10g before the attachment portion 5a of the lid 5 reaches the end of the rectangular through hole 6a of the lid plate 6 in the closing direction.

  Therefore, since the linear motion of the lid 5 is directly stopped by the bearing 10 to which the detection switch 16 is attached, the detection switch 16 can detect the opening / closing operation of the lid 5 with higher accuracy.

  Further, since the lid 5 is biased in the closing direction in this state, even if the camera is used in this state, the lid 5 is prevented from being inadvertently opened or the detection switch 16 being operated to stop the circuit. be able to.
