Description

  The present invention relates to an electronic apparatus including a storage unit that stores a detachable component such as a battery.

  Portable electronic devices that can be carried around, such as digital still cameras and mobile phones, have become widespread. Since general portable electronic devices are driven using a dry battery or a rechargeable battery as a power source, they are provided with a battery storage chamber for storing various batteries serving as a power source. An opening for taking in and out the battery is formed in the battery storage chamber, and a lid is attached to the opening so as not to drop the stored battery.

Electronic devices with a high battery replacement frequency are provided with a spring that biases the battery, and it is common to make a part of the battery protrude and easily take out when the cover of the battery storage chamber is removed. (See Patent Document 1). Also, if the stored battery is always urged by a spring, it will be easier for the battery to pop out when the battery storage chamber lid is removed due to the impact of a drop. (See Patent Documents 2 and 3).

  However, in the prior art described in Patent Documents 2 and 3, since the battery is always urged in the direction of taking out, the battery must be held by the lock claw so that the battery does not move. No battery can be installed. Further, there is a problem that the position of the electrode of the battery is likely to be displaced inside the battery storage chamber due to the biasing force of the spring, and the contact failure of the battery is likely to occur.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an electronic device in which a detachable part such as a battery is difficult to be removed during use and can be easily removed when not in use.

  In order to achieve the above object, the present invention provides a movable member for operating a power switch that is switched between an on position where power is supplied and an off position where power is cut off, In an electronic device having a storage unit for storing a detachable removable component connected to the device, when the movable member is operated at an off position of the power switch, a pressing force is generated in the direction of taking out the removable component. And an extrusion means for extruding the detachable part.

  The push-out means includes transmission means for transmitting a force by which the movable member is operated to the detachable component.

  The transmission means includes an elastic body that is elastically deformed by receiving a force for operating the movable member at an OFF position of the power switch and obtains the pressing force by the restoring force.

  The movable member is operated in a direction perpendicular to a direction in which the detachable part is taken out, and the transmission means is rotated by receiving a torsion spring as the elastic body and a restoring force of the torsion spring, and removing the detachable part. And a pushing cam.

  The movable member is operated in a direction perpendicular to a direction in which the detachable component is taken out, and the transmission means converts a force in a direction in which the movable member is operated into a force in a direction in which the detachable component is taken out; A compression spring is provided that obtains the pressing force by being elastically deformed by the cam.

  The transmission means includes a compression spring as the elastic body and a magnet attached to each of the movable member and the compression spring. The magnets face each other with the same pole facing each other, and the movable member is operated by the movable member. The compression spring is elastically deformed by a magnetic force repelling when the distance between the magnets changes according to the position.

  The storage unit is a battery storage chamber that stores a battery serving as a power source as the detachable part.

  The movable member includes a lens barrier that moves between an open position that exposes the photographing lens and a closed position that covers the photographing lens, and is configured as a photographing device in which the open position of the lens barrier is set to the ON position of the power switch It is characterized by being.

  According to the present invention, in conjunction with the movement of the movable member for turning on and off the power switch, when the power switch is off, a pressing force is generated in the direction of taking out the detachable part such as a battery. Since it extrudes, it can make it easy to make it take out by protruding a part of attachment-detachment component. Since no pressing force is applied to the detachable component when the power switch is on, it is possible to prevent the detachable component from popping out even if the lid is removed due to an impact at the time of dropping or the like. In addition, when a battery or a memory card is applied as a detachable part, a pressing force for pushing them out does not occur at the time of use, so that it is possible to prevent the positions of electrodes and the like from being shifted and causing contact failure.

  In FIG. 1, a digital still camera 10 to which the present invention is applied includes a camera body 11 having a substantially rectangular parallelepiped shape. The camera body 11 is provided with a photographing lens 12, a finder 13 and a strobe light emitting portion 14 on the front surface portion 11a.

On the back surface of the lens barrier 20, a slide pin 24 that slides in the guide groove 21 and a slide pin 25 that slides in the guide groove 22 are provided. The sliding pin 24 and the sliding pin 25 are inserted into the guide groove 21 and the guide groove 22, and members for preventing the removal are attached from the back side of the guide groove 21 and the guide groove 22, respectively. Thereby, the lens barrier 20 is slidably held with respect to the camera body 11.

  On the front surface portion 11a of the camera body 11, power terminals 26a and 26b serving as power switches are provided at positions between the guide grooves 21 and the guide grooves 22. The lens barrier 20 is provided with a conductive plate 27 in contact with the power supply terminals 26a and 26b. When the lens barrier 20 is completely opened, the power supply terminal 26a and the power supply terminal 26b are connected by the conductive plate 27, and the power supply is turned on. On the other hand, when the lens barrier 20 is closed even a little, the power terminal 26a and the power terminal 26b are not connected and the power is turned off.

  In FIG. 3, a battery storage chamber 31 for storing a battery 30 serving as a power source of the digital still camera 10 is provided inside the camera body 11. The battery 30 has, for example, a rectangular plate shape, and is composed of a rechargeable secondary battery. The battery storage chamber 31 has a terminal that contacts the electrode of the battery 30, and the battery 30 can be taken in and out when the lid provided on the bottom surface portion 11 c of the camera body 11 is opened. The battery 30 slides the lens barrier 20 to supply power to the digital still camera 10 when the power terminal 26 a and the power terminal 26 b are connected by the conductive plate 27.

  Inside the camera body 11, there is provided a push cam 32 that pushes the battery 30 toward the bottom surface portion 11 c of the camera body 11 when the battery 30 is taken out. The push cam 32 pushes out the battery 30 to cause a part of the battery 30 to protrude from the battery storage chamber 31, thereby facilitating removal of the battery 30.

  In FIG. 4, the pushing cam 32 is provided with a rotating shaft 36 through which a torsion spring 35 is inserted. The rotation shaft 36 is supported by the camera body 11, and the push cam 32 is rotatably supported. The push cam 32 has a battery pressing surface 37 that presses the battery 30 when rotating, and a spring receiving surface 38 that receives one end 35 a of the torsion spring 35. The other end 35 b of the torsion spring 35 is located on the moving path of the sliding pin 24 that slides in the guide groove 21. The sliding pin 24 presses the end portion 35b of the torsion spring 35 when the lens barrier 20 is closed.

  In FIG. 5, when the end portion 35 b of the torsion spring 35 is pushed by the slide pin 24, the end portion 35 a of the torsion spring 35 pushes the spring receiving surface 38 of the push cam 32, and the push cam 32 is centered on the rotation shaft 36. Rotate clockwise in the figure. When the battery 30 is stored in the battery storage chamber 31, the battery pressing surface 37 comes into contact with the upper surface of the battery 30 when the end portion 35 b of the torsion spring 35 is pressed by the sliding pin 24. The push cam 32 stops with the battery pressing surface 37 in contact with the upper surface of the battery 30. When the end portion 35b of the torsion spring 35 is further pressed by the sliding pin 24, the torsion spring 35 is elastically deformed, and the battery pressing surface 37 of the push cam 32 strongly presses the battery 30 toward the bottom surface portion 11c of the camera body 11. To do.

  Next, the operation of the present invention will be described. When using the digital still camera 10, the lens barrier 20 is opened to expose the taking lens 12 and the like. The sliding pin 24 and the sliding pin 25 slide in the guide groove 21 and the guide groove 22, and the lens barrier 20 slides in the horizontal direction. When the lens barrier 20 is fully opened, the conductive plate 27 of the lens barrier 20 connects the power terminal 26a and the power terminal 26b of the camera body 11, and the power of the digital still camera 10 is turned on. The battery 30 housed in the camera body 11 supplies power, and the digital still camera 10 operates. When the lens barrier 20 is in the open state, the torsion spring 35 is in a natural state, so that the battery 30 is not pressed against the push cam 32.

  After the digital still camera 10 is used, the lens barrier 20 is closed. When the operation of closing the lens barrier 20 is performed, the conductive plate 27 is separated from the power terminals 26a and 26b, and the power of the digital still camera 10 is turned off. When the lens barrier 20 is further closed, the sliding pin 24 comes into contact with the end portion 35 b of the torsion spring 35. The sliding pin 24 presses the torsion spring 35, and the torsion spring 35 receives a force in the direction of rotation about the rotation shaft 36. The end 35 a of the torsion spring 35 presses the spring receiving surface 38 of the push cam 32, and the push cam 32 receives a force in a direction rotating around the rotation shaft 36. The battery pressing surface 37 of the push cam 32 contacts the upper surface of the battery 30, and the battery 30 receives a pressing force corresponding to the restoring force of the torsion spring 35.

  When the lens barrier 20 is completely closed, the amount of elastic deformation of the torsion spring 35 is maximized, and the pushing cam 32 receives the restoring force of the torsion spring 35 and strongly pushes the battery 30 toward the bottom surface 11c of the camera body 11. Press. When the battery 30 is taken out for replacement of the battery 30 or the like, the push cam 32 receiving the force of the torsion spring 35 is opened by opening the cover of the battery storage chamber 31 with the bottom surface portion 11c of the camera body 11 facing upward. The battery 30 is pushed out, and a part of the battery 30 protrudes from the battery storage chamber 31. The battery 30 can be easily taken out by grasping the battery 30 protruding from the battery storage chamber 31.

  As described above, in the digital still camera 10, the opening / closing of the lens barrier 20 and the on / off of the power switch are interlocked, and the push cam 32 does not press the battery 30 when the lens barrier 20 is opened and the power is turned on. When the barrier 20 is closed and the power is turned off, the push cam 32 presses the battery 30. Therefore, the battery 30 is difficult to pop out when the power is turned on, and the battery 30 can be easily taken out when the power is turned off.

  In the above embodiment, the restoring force generated when the sliding pin 24 presses the end 35b of the torsion spring 35 is transmitted to the pushing cam 32, and the pushing cam 32 is rotated to push the battery 30. In the present invention, other configurations can be employed. For example, as shown in FIGS. 6 and 7 as a second embodiment, a taper cam 50 having a tapered surface 50a with which the sliding pin 24 slides, a compression spring 51 connected to the lower portion of the taper cam 50, and a compression spring 51 An extruding plate 52 for extruding the battery 30 in response to the restoring force is provided.

  The sliding pin 24 slides on the taper surface 50a of the taper cam 50 when the lens barrier 20 is closed, and pushes the taper cam 50 downward. The taper cam 50 is restricted in movement so that only a vertical sliding movement can be performed. When the taper cam 50 is pushed down, the compression spring 51 compresses and deforms and pushes down the pushing plate 52. The pushing plate 52 presses the battery 30 and causes a part of the battery 30 to protrude when the battery 30 is taken out. When the lens barrier 20 is open, the sliding pin 24 and the taper cam 50 do not come into contact with each other, so that the compression spring 51 is in a natural state, so that the pushing plate 52 does not press the battery 30. That is, the battery 30 is pressed only when the lens barrier 20 is closed and the power is turned off, and the battery 30 is not pressed when the lens barrier 20 is opened and the power is turned on.

  As a third embodiment, as shown in FIG. 8, a first magnet 60 is provided on the sliding pin 24, a second magnet 61 is provided at a position facing the magnet 60, and compression is performed below the magnet 61. A spring 62 and an extrusion plate 63 are provided. The magnet 60 and the magnet 61 are provided so that the N poles face each other. When the lens barrier 20 is closed, the sliding pin 24 approaches the magnet 61, and a repulsive magnetic force is generated between the magnet 60 and the magnet 61. The magnet 61 is attached to a support plate 64 whose movement is restricted so that only a vertical sliding movement can be performed. The magnet 61 is pushed downward by a repulsive force generated between the magnet 61 and the compression spring 62 to be compressed. The pushing plate 63 is pushed downward by the compression spring 62 and presses the battery 30. In a state where the lens barrier 20 is open, the magnet 60 and the magnet 61 are separated from each other, so that the compression spring 62 is in a natural state, and the pushing plate 63 does not press the battery 30. That is, the battery 30 is pressed only when the lens barrier 20 is closed and the power is turned off, and the battery 30 is not pressed when the lens barrier 20 is opened and the power is turned on.

  In FIG. 9 showing the fourth embodiment, the direction in which the battery 30 is attached to the camera body 11 and the direction in which the battery 30 is detached from the camera body 11 is parallel to the opening / closing direction of the lens barrier 20. The lens barrier 20 is provided with a leaf spring 70 as an elastic body that presses the battery 30. The leaf spring 70 has a fixing portion 70 a fixed to the lens barrier 20, and enters the inside of the camera body 11 through an opening 71 that is elongated in the horizontal direction provided in the camera body 11. The leaf spring 70 moves along the opening 71 when the lens barrier 20 is opened and closed. In a state where the lens barrier 20 is closed, the leaf spring 70 contacts the battery 30 and presses the battery 30. Thus, when the lens barrier 20 is closed, when the battery 30 is taken out, the battery 30 is pushed out and becomes easy to take out. In a state where the lens barrier 20 is opened, the leaf spring 70 is separated from the battery 30 and the battery 30 is not pressed, so that it is difficult for the battery 30 to jump out to the outside when an impact is applied to the camera body 11.

  The present invention can be applied to other electronic devices different from a digital still camera. For example, the present invention can be applied to a mobile phone or a computer terminal as a portable electronic device using a battery. In addition to the battery, an information storage medium such as a memory card or an IC card may be applied as a detachable part that is detachably attached to the apparatus main body. Further, in order to push out the detachable component, the force when moving the movable member is transmitted to an elastic body such as a torsion spring, and the pressing force is generated using the restoring force of the elastic body. And a sensor that detects the position of the movable member, etc., and the driving source is set according to the position of the movable member so that the pressing force is generated when the power switch is turned off and the pressing force disappears when the power switch is turned on. It may be driven.
