  Also, on the left side of the upper surface of the camera body 12, a release button 16 that is pressed down (ie, turned on) by the photographer when the digital camera 11 starts an imaging operation, and the digital camera 11 is turned on. A power switch 17 that is sometimes pushed down by the photographer is provided. A monitor of a liquid crystal display (hereinafter referred to as “LCD 18”) (see FIG. 4) or the like is provided on the rear side of the camera body 12.

  As shown in FIG. 1, a battery lid 20 is attached to the bottom left portion of the camera body 12 so as to be opened and closed by rotating about the right end side in FIG. Inside the camera body 12, there is provided a battery housing chamber 21 (battery chamber) whose opening is covered by a battery lid 20 arranged at the closed position shown in FIG. A power supply battery 22 can be inserted into the battery storage chamber 21 by opening and closing the battery lid 20, and the power supply battery 22 is stored in the battery storage chamber 21. The power supply battery 22 is composed of a rechargeable battery such as a lithium ion rechargeable battery. The digital camera 11 can receive power from the power supply battery 22 or can receive external power from an SC adapter (not shown) or the like using a DC input terminal (not shown). .

  Further, a card slot 23 whose opening is covered by the battery lid 20 disposed at the closed position shown in FIG. 1 is provided in the camera body 12 at a position adjacent to the battery housing chamber 21. A memory card 24 (external storage medium), which is a removable storage medium (portable storage medium), is inserted into the card slot 23. The digital camera 11 of the present embodiment is compatible with a small memory card 24, and the card slot 23 is formed in a size that allows the small memory card 24 to be inserted. Therefore, even if the storage system is the same, a large memory card cannot be used. Further, the camera body 12 is provided with a detection switch 26 that can detect the opening / closing of the battery lid 20 at a position near the rotation center of the battery lid 20 (near the right end in FIG. 1).

The memory card includes a small memory card 24 shown in FIG. 2A, which is a size compatible with the digital camera 11, and a large size shown in FIG. 2B, which is a size not compatible with the digital camera 11. There is a memory card 25. Specifically, in this example, the small memory card 24 is a “micro SD card”, and the large memory card 25 is an “SD card”.

  Since the card slot 23 has a hole size corresponding to the small memory card 24, the card slot 23 has a hole size not compatible with the large memory card 25. Direct insertion is impossible. Therefore, in this embodiment, it is possible to electrically connect the “SD card”, which is a large memory card 25, with a terminal in the card slot 23 through a conversion adapter described later.

  FIG. 3 is a schematic cross-sectional view showing a part of a detection mechanism that detects opening and closing of the battery lid 20. FIG. 3A shows a state where the battery cover 20 is opened in the digital camera 11 of the present embodiment, and FIG. 3B shows a state where the battery cover 20 is closed.

  As shown in FIG. 3, a main board 27 on which a detection switch 26 is mounted is provided inside the camera body. The main board 27 includes an apparatus (a memory card reader / writer) in the card slot 23, and a RAM 53 and a ROM 52 that partially function as a buffer memory for temporarily storing image data captured by the digital camera 11. A microcomputer 40 for controlling each part in an integrated manner (see FIG. 4 for all) and various other circuits are mounted.

The battery cover 20 is attached so as to be rotatable about a support shaft 28 provided on the camera body 12 side.
The camera body 12 is provided with a detection switch 26 that can detect the opening and closing of the battery lid 20 at a position near the rotation center of the battery lid 20 (near the right end in FIG. 3). The detection switch 26 has a main body 26a and a contact piece 26b biased in a direction away from the contact point of the main body 26a.

The image sensor 41 has, for example, 1600 × 1200 pixels and is imaged by the imaging lens 13. The converted light image of the subject is photoelectrically converted into an image signal of R (red), G (green), and B (blue) color components for each pixel (a signal composed of a signal sequence of pixel signals received by each pixel). And output.

  An image signal obtained from the image sensor 41 is given to the analog signal processing circuit 42. The analog signal processing circuit 42 includes a correlated double sampling (CDS) circuit and an auto gain control (AGC) circuit. The analog signal processing circuit 42 performs noise reduction processing of the image signal by the correlated double sampling circuit, and adjusts the level of the image signal by adjusting the gain by the auto gain control circuit.

  The A / D converter 43 converts each pixel signal of the image signal into a 12-bit digital signal. The converted digital signal is temporarily stored in the buffer memory 53a in the RAM 53 as image data. Then, after color correction processing or the like is performed on the image data stored in the buffer memory 53a, compression processing or the like by the compression processing unit 57 is performed.

  Note that the digital camera 11 of the present embodiment is capable of video shooting and includes a microphone and a speaker (not shown). Audio processing for performing various digital processing on audio data is performed by an audio processing circuit (not shown) provided in the control unit 51.

  The operation unit 44 is an operation unit including the release button 16 and the power switch 17 described above, and is used when the user changes the setting state of the digital camera 11 or performs a shooting operation.

  The flash 14 is controlled to emit light by the microcomputer 40. The microcomputer 40 determines the color temperature of the necessary illumination light based on the color information of the ambient light acquired by the photometric element (not shown), and the flash 14 emits the illumination light having the color temperature determined by the microcomputer 40.

  The USB terminal 45 is provided on the side surface of the camera body 12 and can be connected to a USB cable connector. The digital camera 11 is connected to, for example, a personal computer (not shown) via a USB cable connected via the USB terminal 45, and performs communication such as transmission / reception of image data with the personal computer. Further, when the digital camera 11 is connected to a personal computer or the like through a USB cable, the digital camera 11 is driven using bus power supplied through the USB cable as a power source. Further, the power source battery 22 is charged using the bus power supplied through the USB cable.

The power battery 22 is a power supply source for the digital camera 11. The digital camera 11 is driven using a secondary battery such as a lithium ion battery as a power source.
The power supply circuit 48 is driven by an instruction from the microcomputer 40, generates a voltage necessary for each part of the digital camera 11 based on a supply voltage of the power supply battery 22, and supplies a necessary voltage to each part.

The real-time clock 46 is used to acquire the current time, and is used to acquire the shooting date and time required for date imprinting.
The microcomputer 40 is configured to include a control unit 51, a ROM 52, and a RAM 53 therein, and the microcomputer 40 executes a predetermined program so as to comprehensively control the above-described units. The ROM 52 is an electrically rewritable nonvolatile semiconductor memory (for example, a flash ROM), and the RAM 53 is a high-speed accessible semiconductor memory. A part of the area in the RAM 53 is used as a buffer memory 53a that functions as a buffer area for temporary storage. The buffer memory 53a temporarily stores image data.

  The control unit 51 includes an image processing unit 56, a compression processing unit 57, and a power supply control unit 58. Each of these processing units 56 to 58 is a functional unit realized by the microcomputer 40 executing a predetermined program.

  The image processing unit 56 is a processing unit that performs various digital image processing such as white balance processing (WB processing) and γ correction processing. The WB process is a process for adjusting the color balance by converting the level of each of the R, G, and B color components. The γ correction process is a process for correcting the gradation of pixel data. As the compression method, for example, the JPEG method is adopted.

  The microcomputer 40 performs processing in the shooting mode and the playback mode. For example, when the release button 16 is half-pressed by the operator in the photographing mode, an AE evaluation value is obtained based on the image data output from the image sensor 41, and the photographing lens is moved to the in-focus position by a known hill-climbing method. Further, based on the luminance information of the subject read by the image sensor 41, the shutter speed, aperture value, and auto white balance gain value at the time of actual photographing are determined.

  When the ON signal is input from the detection switch 26, the power control unit 58 determines that the battery cover 20 is in a closed state, and instructs the power supply circuit 48 to drive the digital camera 11 to power on. Further, when the power control unit 58 inputs an off signal from the detection switch 26, the power control unit 58 determines that the battery cover 20 is opened, and stops driving the power circuit 48 to power off the digital camera 11.

  On the other hand, when the release button 16 is fully pressed in the photographing mode, the microcomputer 40 photographs the subject after setting the resolution of the image sensor 41 to a high resolution, and compresses based on the photographed image data acquired by the image sensor 41. The processing unit 57 generates a compressed image. The compressed captured image data is stored in the memory card 24 that functions as a storage medium.

The card I / F 47 is an interface for writing and reading image data to and from the memory card 24 inserted in the card slot 23 of the digital camera 11.
When reading / writing image data from / to the memory card 24, the compression processing unit 57 compresses image data, for example, in JPEG format, and the image data is transmitted / received between the buffer memory 53a and the memory card 24 via the card I / F 47. Is done. In addition, when reading / writing audio data, the audio data is transmitted / received between the buffer memory 53a and the memory card 24 via the card I / F 47.

FIG. 5 shows the battery cover with the adapter attached integrally, and FIG. 6 shows the battery cover with the adapter removed, where (a) is a plan view and (b) is a side view.
As shown in FIG. 5, a substantially annular guide portion 60 into which the support shaft 28 (see FIG. 3) on the camera body 12 side is inserted is formed at one end (the right end in FIG. 5) of the battery lid 20. Further, a hook (not shown) is formed on the other end (left end in FIG. 5) of the battery lid 20 to engage with a locking recess on the camera body 12 side.

  The battery lid 20 is configured to be separable into two parts, and includes a lid body 30 that constitutes a rotation center side portion, and an adapter 31 that constitutes a rotation tip side portion. That is, a part removed from the lid body 30 constituting the battery lid 20 functions as the adapter 31.

  The lid body 30 is provided with a slot 30 a that opens on the surface on the connection side with the adapter 31. The slot 30a is formed in a size that allows a small memory card 24 to be inserted. The lid main body 30 is provided with a fitting recess 30b having an opening shape longer in the width direction (vertical direction in FIG. 6) than the slot 30a in the vicinity of the opening of the slot 30a.

  The adapter 31 includes a square plate-shaped adapter main body 61, a plate-shaped terminal portion 62 protruding from the tip end portion in the insertion direction (right direction in FIG. 6) of the adapter main body 61, and a movable type attached to the adapter main body 61. It is comprised by the press part 63. FIG. The adapter main body 61 is formed with a slot 31a which is open on the end surface opposite to the insertion direction side and into which the large memory card 25 can be inserted. The terminal portion 62 has substantially the same shape as the small memory card 24 (“micro SD card” in this example), and can be inserted into the card slot 23. The terminal portion 62 has the same terminal as that of the small memory card 24. When the terminal portion 62 is inserted into the card slot 23, the terminal at the tip thereof is the card slot 23 (card I / F 47). It is electrically connected to the terminal on the side.

  Further, a fitting convex portion 61 a that can be fitted to the fitting concave portion 30 b on the lid main body 30 side is formed at a position near the base portion of the terminal portion 62 in the adapter main body 61. For this reason, the adapter 31 is integrally connected to the lid body 30 with a certain degree of strength by the force with which the fitting convex portion 61a is fitted to the fitting concave portion 30b. Of course, a lock mechanism (locking mechanism) for locking the lid main body 30 and the adapter 31 can be provided. In this case, when the adapter 31 is inserted into the lid main body 30, the adapter 31 is locked to the lid main body 30 by the operation of the lock mechanism, and the user pulls the adapter 31 while pushing the operation unit for unlocking to lock the lock mechanism.

The pressing portion 63 is a storage position (position indicated by a broken line in FIG. 6A) stored in the adapter main body 61 and a position rotated about 180 degrees from the storage position. It can be arranged at a protruding position (a position indicated by a two-dot chain line in FIG. 6A) as a detected position protruding vertically with a predetermined protruding amount. For example, the pressing portion 63 is locked by a locking portion (not shown) at two positions, that is, a storage position and a protruding position, and is positioned at the locked position. The locking of the pressing portion 63 is released by a force when the user manually rotates the pressing portion 63. Of course, a configuration may be employed in which the pressing portion 63 is held at the storage position and the protruding position by frictional resistance without providing the locking portion.

  FIG. 7 is a partial schematic front view illustrating a usage method when the adapter is inserted into the digital camera 11 and used. FIG. 7A shows a state before adapter insertion, and FIG. 7B shows a state after adapter insertion.

  As shown in FIG. 7A, when the adapter 31 is attached to the digital camera 11, first, the battery lid 20 is opened, and the tip end portion of the battery lid 20 is pulled out to remove the adapter 31 from the lid body 30. . In this state, the pressing portion 63 is disposed at the storage position. Next, as shown by an arrow in FIG. 7A, the pressing portion 63 is rotated from the storage position so that the solid line in FIG. Arranged at the protruding position shown. Before and after this, a large-sized memory card 25 that does not correspond to the card slot 23 on the digital camera 11 side is inserted into the slot 31 a of the adapter 31. Then, the terminal portion 62 of the adapter 31 from which the pressing portion 63 protrudes is inserted into the card slot 23 of the digital camera 11.

  As shown in FIG. 7B, when the terminal portion 62 of the adapter 31 is inserted into the card slot 23, the pressing portion 63 pushes the contact piece 26b of the detection switch 26 into contact with the contact on the main body 26a side. . As a result, when the adapter 31 is inserted into the card slot 23, the detection switch 26 is turned on even when the battery cover 20 is open. Therefore, even if the adapter 31 inserted in the card slot 23 gets in the way and the battery cover 20 cannot be closed, the detection switch 26 is turned on. Therefore, the digital camera 11 with the adapter 31 inserted can be powered on even with the battery cover 20 open. As a result, the digital camera 11 can be normally activated, and photographing can be performed.

As described above in detail, according to the first embodiment, the following effects can be obtained.
(1) When the adapter 31 is inserted into the card slot 23, a pressing portion 63 as a detected portion provided in the adapter main body 61 is detected by the detection switch 26, and the power of the digital camera 11 is turned on. Therefore, even if the adapter 31 inserted in the card slot 23 or the memory card 25 of an unsupported size becomes in the way and the battery cover 20 cannot be closed, the power of the digital camera 11 can be turned on. As a result, the digital camera 11 can access the memory card 25 having a non-corresponding size. For example, data can be read from the memory card 25 and data can be written.

  (2) Since the pressing portion 63 is provided so as to be movable between the storage position and the detected position, the pressing portion 63 is stored when not in use and does not obstruct, and when the adapter 31 is used, the pressing portion 63 is manually rotated. By operating it, it can be easily moved from the storage position to the detected position.

  (3) The detection switch 26, which is a kind of contact sensor, is employed as the detection means, and the detected portion is a pressing portion 63 that can press the contact piece 26b of the detection switch 26. Therefore, since the protrusion part which can press a contact-type sensor should just be provided as the press part 63, the to-be-detected part of the adapter 31 can be made into a comparatively simple structure.

(Second embodiment)
Next, a second embodiment will be described based on the drawings. The present embodiment is an example in which the pressing portion, which is a rotary type in the first embodiment, is a slide type. In addition, description is abbreviate | omitted about the structure which is common in 1st embodiment, and only a different part is demonstrated.

FIG. 8 shows a plan view of the adapter in the second embodiment. FIG. 8A shows a state where the pressing portion is disposed at the protruding position, and FIG. 8B shows a state where the pressing portion is disposed at the storage position.
As shown in FIG. 8, a slide type pressing portion 63 is provided on the adapter main body 61 from which a micro SD card type terminal portion 62 protrudes at the tip end portion.
