  The digital camera of the present invention includes a camera body in which an imaging lens is disposed, and a lens barrier that is assembled to the camera body so as to be movable between a position that covers the imaging lens and a position that exposes the imaging lens. The lens barrier includes a storage medium holding unit that holds a recording medium that records image data obtained by imaging at least, and the lens barrier is at a position where the imaging lens is exposed. Since the storage medium held in the storage medium holding part is prevented from being detached when moved, the thickness of the camera main body can be obtained by providing the storage medium holding part not in the camera main body but in a lens barrier having a sufficient space. This can contribute to the reduction in thickness.

  The lens barrier includes a loading port for inserting and removing the storage medium into and from the storage medium holding unit, and the loading port is covered by the camera body when the lens barrier moves to a position where the imaging lens is exposed.

  FIG. 1 is a perspective view showing the external configuration of the front surface of the digital camera of the present invention, and FIG. 2 is a perspective view showing the external configuration of the rear surface. The digital camera 10 has a configuration in which a lens barrier 12 is provided on a front surface 11 a of a horizontally long camera body 11. On the front surface 11a of the digital camera 11, a photographing lens 15 and a strobe light emitting unit 16 (see FIG. 6) are provided at the upper edge. A release button 17 is provided on the upper surface 11 b of the digital camera 11.

  An LCD (liquid crystal display) 20 and an operation unit 21 are provided on the back surface 11 c of the camera body 11. The LCD 20 is used as a so-called electronic viewfinder that displays a subject image captured by an imaging device (not shown) such as a CCD, and also displays an image using image data stored in a media card 45 or the like described later. In addition, when a setting is changed, a setting menu is displayed. The operation unit 21 includes a zoom operation button 22, a menu button 23, a cross key 24, and the like, and is operated at the time of imaging or setting.

  On the front surface 11a of the camera body 11, ribs 26 to 28 are formed at both ends in the longitudinal direction and at the lower end in the width direction. Among these ribs 26 to 28, when the lens barrier 12 is in a position where the lens barrier 12 covers the imaging lens 15 (hereinafter referred to as a closed position), one side surface 12a of the lens barrier 12 abuts, and the rib 27 When the barrier 12 is at a position where the imaging lens 15 is exposed (open position), one side surface 12b of the lens barrier 12 is brought into contact. The ribs 28 are provided so as to face the lower surface 12 c of the lens barrier 12. The rib 28 extends from the rib 27 in the longitudinal direction of the camera body 11.

The loading port 42 is exposed to the outside by a space 30 between the rib 26 and the rib 28 provided in the camera body 11 when the lens barrier 12 is in the closed position. When the lens barrier 12 moves from the closed position to the open position, the loading port 42 is covered with the rib 28. Thus, when the lens barrier 12 is in the closed position, the media card 45 can be inserted and removed.

  As described above, the circuit board 41 is electrically connected to the media slot 40. The circuit board 41 includes a media controller 46 that writes image data to the media card 45 loaded in the media slot 40 and reads image data written on the media card 45. The circuit board 41 is provided with a position detection switch 47 that detects the opening position of the lens barrier 12. The position detection switch 47 is turned off when the lens barrier 12 is in the closed position, and turned on when the lens barrier 12 is slid from the closed position to the open position. When the position detection switch 47 is turned on, power is supplied to the digital camera 10, and the digital camera 10 can capture a subject image or display image data. Thereby, the position detection switch 47 functions as a power switch. The position detection switch 47 may be any switch that can detect whether the lens barrier is in the open position or the closed position.

  As shown in FIG. 6, the camera body 11 includes a control circuit board 50 that controls driving of the LCD 20, the strobe light emitting unit 16, and the like. Openings 53 and 54 through which connection terminals 51 and 52 assembled to the control circuit board 50 are inserted are provided on the front surface 11 a of the camera body 11. These connection terminals 51 and 52 are inserted into openings 56 and 57 provided on the back surface 12 d of the lens barrier 12, respectively, and come into contact with the circuit pattern of the circuit board 41 provided on the lens barrier 12. Thereby, the control circuit board 50 provided in the camera body 11 and the circuit board 41 of the lens barrier 12 are electrically connected.

  Thus, by providing the lens barrier 12 with the media slot 40 and the circuit board 41 connected to the media slot 40, the number of components incorporated in the camera body 11 can be reduced. The thickness of 11 can be reduced. Further, by providing the circuit board 40 provided on the lens barrier 12 with the position detection switch 60 that functions as a power switch, it is not necessary to provide a power button (or power switch) on the camera body 11. Furthermore, by directly assembling the position detection switch 47 to the circuit board 41 built in the lens barrier 12, it is not necessary to assemble it via a harness or the like.

  In the present embodiment, the control circuit board 50 provided in the camera body 11 and the circuit board 41 built in the lens barrier 12 are connected by connection terminals 51 and 52 provided in the control circuit board 41, and the lens barrier 12. When the position detection switch 47 provided on is turned on, power is supplied to the control circuit board 50 and the circuit board 41. However, the present invention is not limited to this. The circuit board 40 provided on the lens barrier 12 may be electrically connected to the control circuit board 50 provided on the camera body 11 when sliding from the closed position to the open position. In this case, when the lens barrier 12 slides to the open position, the connection terminal protruding from the camera body 11 is brought into contact with the circuit pattern of the circuit board 40 provided on the lens barrier 12. According to this, since it is not necessary to provide a position detection switch, the number of parts can be reduced.

  In these cases, data transmission / reception between the control circuit board provided in the camera body and the circuit board provided in the lens barrier may be performed by infrared communication. In the following, portions having the same functions as those of the present embodiment will be described with the same reference numerals as those of the present embodiment. For example, as shown in FIG. 7, a transmission / reception unit 65 capable of transmitting and receiving infrared rays is provided on the control circuit board 50 provided in the camera body 11 and exposed from an opening 66 provided in the front surface 11 a of the camera body 11. Further, the lens barrier 12 includes a substantially box-shaped barrier body 68 having an opening on the back surface and a lid member 69 that covers the back surface of the barrier body 68, and the circuit board 41 provided with a transmission / reception unit 70 capable of transmitting and receiving infrared rays is used as a barrier. It is housed inside the main body 68. Further, an opening 71 is provided in the lid member 69, and the transmission / reception unit 70 is exposed from the opening 71. For example, when the lens barrier 12 moves from the closed position to the open position, the transmitting / receiving unit 65 provided on the control circuit board 50 and the transmitting / receiving unit 70 of the circuit board 41 provided on the lens barrier 12 face each other. Data transmitted / received from one transmitter is received and received by the other receiver. In addition to infrared communication, wireless communication can also be performed. In this case, it is necessary to use a frequency that is not used by other devices for radio waves used for radio. Reference numeral 75 denotes a lens barrel.

As shown in FIG. 9, when the lens barrier 12 is moved from the closed position to the open position, the relative position between the heat radiation opening 80 and the cover portion 81 changes, and the heat radiation opening 80 is opened. Therefore, the heat generated by the circuit component 82 such as a media controller incorporated in the circuit board 41 can be released from the gap between the lens barrier 12 and the front surface of the camera body 11. Further, as shown in FIG. 8, when the lens barrier 12 is slid to the closed position, the heat radiation opening 80 is covered with the cover portion 81. Mixing can be prevented. The heat dissipation opening 80 is not necessarily limited to the back surface of the lens barrier 12, and may be provided on the top surface or the bottom surface.

In this case, as shown in FIGS. 10 and 11, a slide volume (movement amount detecting means) 90 is provided on the control circuit board 50 provided in the camera body 11, and the slide piece 91 of the slide volume 90 is associated with the lens barrier 12. Combine. In this case, as shown in FIG. 10, when the imaging lens 15 is exposed, the change in the resistance value of the slide volume 90 is validated, and the zoom magnification is changed using the change in the resistance value of the slide volume. For example, when the lens barrier 12 is moved in the A direction in FIG. 10, the zoom magnification changes to the wide (wide angle) side, and when the lens barrier 12 is moved in the B direction in FIG. 11, the zoom magnification is set to the tele (telephoto) side. Change. As a result, there is no need to provide a zoom operation button provided on the back surface of the camera body 11, and the number of parts can be reduced. Note that the method for detecting the position change of the lens barrier 12 is not limited to the slide volume 90, and for example, a rotary encoder may be used.

  Further, a USB connection type storage medium may be connected. In this case, as shown in FIG. 12, the USB connector portion 100 is provided on the lens barrier 12. In addition, the rib 26 provided on the camera body 11 is provided with a recess 26 a into which the storage medium 102 having the USB connector 101 can be inserted. By providing such a recess 26 a in the rib 26, the storage medium 102 can be connected even when the lens barrier 12 is in the closed position. Thereby, in addition to the media card 45, other types of memories can be connected, so that compatibility with other memories can be improved.

  In addition to this, it is also possible to provide a mechanism for cleaning the imaging lens in the lens barrier when the lens barrier is in the closed position. As shown in FIG. 13, the lens barrier 12 is provided with a cleaning mechanism 110, and the cleaning mechanism 110 includes a cleaning brush 111 and a motor 112 that rotates the cleaning brush 111. Further, an opening 113 is provided in the lid member 69 constituting the lens barrier 12 to expose the brush part 111a of the cleaning brush 111. Although not shown, a circuit of the circuit board 41 is configured by including a capacitor in the circuit components of the circuit board 40 provided on the lens barrier 12. In this circuit, a circuit for storing power in the capacitor and a circuit for driving the motor 111 using electricity stored in the capacitor are provided. Further, a switch that is turned on when the lens barrier 12 is in the open position is provided in a circuit that stores electricity in the capacitor, and a switch that is turned on when the lens barrier 12 is in the closed position is provided in the circuit that drives the motor 112. As a result, when the lens barrier 12 is slid to the open position, electricity is stored in the capacitor, and when the lens barrier 12 is slid to the closed position, the motor 112 is driven to rotate the cleaning brush 111 and the imaging lens 15 The surface can be cleaned. Note that the motor 112 stops when the power stored in the capacitor is consumed. Reference numeral 113 denotes a lens barrel.

  In addition to this, as shown in FIG. 14, the circuit element 120 having a large calorific value among the circuit elements assembled to the circuit board 41 provided in the lens barrier 12 is replaced with an imaging lens when the lens barrier 12 is in the closed position. It is also possible to arrange the front surface of 15 or the vicinity thereof. According to this, after using the digital camera, it becomes possible to warm the imaging lens 15 using the residual heat of the circuit element 120, and therefore, condensation of the imaging lens 15 can be prevented.
