The function operated by the push button 23 or the command dial 24 is arbitrary. For example, the push button 23 is pressed to enter a setting mode such as exposure correction or ISO sensitivity setting, and the setting value is changed by rotating the command dial 24. Can be made. The illumination button 20 is used, for example, for turning on / off the LEDs (auxiliary illumination) 34, 36, 43, 51.

  A remote control light receiving window 25 is provided in the lower part of the front surface of the finger grip 16 a of the grip 16, and an infrared signal from a wireless remote controller (not shown) is received by the remote control light receiving window 25. A battery storage chamber 28 (FIG. 4) is formed inside the grip portion 16, and the battery can be inserted into and removed from the battery storage chamber by opening an openable and closable battery cover provided on the lower surface of the camera body 10. A tripod screw portion is formed on the lower surface of the camera body 10. The battery lid and tripod screw are not shown in the drawing.

  A card holding unit 30 is provided in the grip portion 16 at a portion rearward of the finger hanging portion 16a. As shown in FIG. 1, the card holding unit 30 is provided on the side surface of the grip portion 16 (near the rear edge of the right side surface of the camera body 10), and is provided with a card lid 31 that can be opened and closed.

  As shown in FIGS. 3 and 4, a flat memory card (for example, a recording medium for recording image data) (not shown) can be inserted / removed inside the card lid (lid portion) 31. Two card slots 32 and a card slot 33 are provided. The card slot 32 and the card slot 33 are offset from each other in the vertical direction (the direction orthogonal to the flat surface of the memory card and the direction of insertion / removal).

  The card slot 32 is located on the front side of the card slot 33, and the memory card inserted into the insertion / extraction port 32A is located at the back (left side) of the insertion / extraction port 32A for inserting / removing the memory card. And a card storage portion 32B for storing the card.

  The card storage part 32B includes a storage space 32C in which the inserted memory card is located, and a non-storage space (gap) 32D located on the rear side of the storage space 32C. A main board 26 is provided on the opposite side of the accommodation space 32C across the non-accommodation space (gap) 32D. The main board 26 is located in the non-accommodation space (gap) in the memory card insertion / removal direction (left / right direction). It is arranged to extend along 32D.

  In addition, an LED (auxiliary illumination) 34 that supplies illumination light to an illumination path that reaches the card accommodation portion 32B and the insertion / extraction port 32A is provided inside the card accommodation portion 32B. Specifically, the LED 34 is provided on the front surface of the main board 26, that is, on the rear side wall 32E of the card housing portion 32B. Thereby, light leaking directly from the insertion / extraction port 32A to the outside of the camera body 10 can be reduced, and discomfort such as entering the eyes of the user or a third party and being dazzling can be given to the user or the third party. Can be avoided. Further, since the insertion / extraction port 32A can be pinpointed from the inside of the card housing portion 32B and the inside of the card housing portion 32B, the card slot 32 can be efficiently illuminated, and the visibility of the card slot 32 in the darkness is improved. be able to. As a result, the operability of the insertion / extraction operation of the memory card to / from the card slot 32 in the dark can be improved. Further, when the memory card is inserted into the card slot 32, the LED 34 can illuminate the flat surface of the memory card via the non-accommodating space (gap) 32D. Thereby, since the memory card can be illuminated over a wide area, the operability of the memory card removal operation can be improved.

  The light emitting surface of the LED 34 is covered with a diffusion sheet (diffusion member) 35 that diffuses the light emitted from the LED 34. Thereby, the insertion / extraction port 32A can be efficiently illuminated over a wide area from the inside of the card housing portion 32B and the inside of the card housing portion 32B. Here, the diffusion sheet (diffusion member) 35 does not necessarily have to cover the light emitting surface of the LED 34, and may be disposed, for example, between the light emitting surface of the LED 34 and the insertion / extraction port 32 </ b> A. In short, it is only necessary that the light emitted from the LED 34 can be diffused widely by the diffusion sheet (diffusion member) 35.

  Further, on the right side of the rear side wall 32E of the card housing portion 32B provided with the LED 34, there is provided a right side wall 32F positioned so as to be substantially orthogonal to the rear side wall 32E and adjacent to the insertion / extraction port 32A on the rear side. In other words, the LED 34 is positioned one step behind the insertion / extraction port 32A. For this reason, most of the light emitted from the LED 34 in the memory card removal direction and passing through the non-accommodating space (gap) 32D can be reliably shielded by the right side wall (light shielding wall) 32F. Thereby, it is possible to reliably avoid the light of the LED 34 leaking directly from the insertion / extraction port 32A to the outside of the camera body 10 when the memory card is not accommodated and when the accommodation is completed.

  On the other hand, the card slot 33 has an insertion / removal port 33A for inserting / removing a memory card, and a card accommodating portion 33B which is located at the back (left side) of the insertion / removal port 33A and accommodates a memory card inserted from the insertion / removal port 33A. doing. The card housing portion 33B and the card housing portion 32B are partitioned by the main board 26. That is, the main board 26 serves as a partition wall between the card housing portion 33B and the card housing portion 32B.

  The card accommodation portion 33B includes an accommodation space 33C in which the inserted memory card is located, and a non-accommodation space (gap) 33D located on the rear side of the accommodation space 33C. A switch board 27 is provided on the opposite side of the accommodation space 33C across the non-accommodation space (gap) 33D, and the switch board 27 is not accommodated in the insertion / extraction direction (left / right direction) of the memory card. It is arrange | positioned so that it may extend along 33D.

  In addition, an LED (auxiliary illumination) 36 that supplies illumination light to an illumination path that reaches the card accommodation portion 33B and the insertion / extraction port 33A is provided inside the card accommodation portion 33B. Specifically, the LED 36 is provided on the front surface of the switch board 27, that is, on the rear side wall 33E of the card housing portion 33B. Thereby, similarly to the card slot 32, the light leaking directly from the insertion / removal port 33A to the outside of the camera body 10 can be reduced, and the user feels uncomfortable feeling such as being dazzled by the eyes of the user or a third party. Or giving to a third party can be avoided. Further, similarly to the card slot 32, the operability of the operation of inserting / removing the memory card into / from the card slot 33 in the dark can be improved.

  The light emitting surface of the LED 36 is covered with a diffusion sheet (diffusion member) 37 that diffuses the light emitted from the LED 36. Accordingly, the insertion / extraction port 33A can be efficiently illuminated over a wide area from the inside of the card housing portion 33B and the inside of the card housing portion 33B. Here, the diffusion sheet (diffusion member) 37 does not necessarily have to cover the light emitting surface of the LED 36, and may be disposed, for example, between the light emitting surface of the LED 36 and the insertion / extraction port 33 </ b> A. In short, it is only necessary that the light emitted from the LED 36 can be diffused widely by the diffusion sheet (diffusion member) 37.

  Further, on the right side of the rear side wall 33E of the card accommodating portion 33B provided with the LED 36, a right side wall 33F is provided so as to be substantially orthogonal to the rear side wall 33E and adjacent to the insertion / extraction port 33A on the rear side. In other words, the LED 36 is positioned one step behind the insertion / extraction port 33A. For this reason, most of the light emitted from the LED 36 in the memory card removal direction and passed through the non-accommodating space (gap) 33D can be reliably shielded by the right side wall (light shielding wall) 33F. Thereby, it is possible to reliably avoid the light of the LED 36 leaking directly from the insertion / extraction port 33A to the outside of the camera body 10 when the memory card is not accommodated and when the accommodation is completed.

  Here, the card lid (lid portion) 31 extends in front of the insertion / extraction port 32A in the longitudinal direction of the insertion / extraction port 32A (a direction orthogonal to both the flat surface of the inserted memory card and the insertion / extraction direction). A closed state (shown in FIGS. 1 and 2) that is pivotally supported on the camera body 10 by the rotary opening / closing shaft 31A and closes the insertion / extraction port 32A and the insertion / extraction port 33A from the outside of the camera body 10, and the insertion / extraction port 32A and the insertion / extraction port 33A are opened. It is configured to be able to open and close between the open state. For this reason, in the open state, the card cover 31 is located in front of the insertion / extraction port 32A. That is, in the opened state, the card cover 31 is located on the opposite side of the LED 34 with the insertion / extraction port 32A interposed therebetween, and is located on the opposite side of the LED 36 with the insertion / removal port 33A interposed therebetween. Thereby, the light that has leaked from the insertion / extraction port 32 </ b> A and the insertion / extraction port 33 </ b> A can be reliably shielded by the card lid 31. That is, the open card cover 31 prevents light from leaking to the front of the camera body 10.

  The LEDs 34 and 36 are offset in the vertical direction in accordance with the vertical offset arrangement of the card slot 32 and the card slot 33 (the offset layout of the insertion / extraction port 32A and the insertion / extraction port 33A). Thereby, the discriminability between the card slot 32 and the card slot 33 can be improved.

  The LEDs 34 and 36 are offset in the left-right direction (card slot insertion / extraction direction). That is, the separation distance in the insertion / extraction direction from the insertion / extraction opening 32A to the LED 34 is different from the separation distance in the insertion / extraction direction from the insertion / extraction opening 33A to the LED 36. Specifically, the separation distance in the insertion / extraction direction from the insertion / extraction opening 33A to the LED 36 is shorter than the separation distance in the insertion / extraction direction from the insertion / extraction opening 32A to the LED 34. Thereby, the discriminability between the card slot 32 and the card slot 33 can be improved.

  Further, the right end surface of the main board 26 and the right side wall 32F are separated from each other. That is, the card storage portion 32B and the card storage portion 33B communicate with each other between the right end surface of the main board 26 and the right side wall 32F. Thereby, a part of the light emitted by the LED 36 can illuminate the insertion / extraction port 32A from the inside of the card housing portion 32B. For this reason, the following light emission control can be performed on the LED 34 and the LED 36. For example, when both the card slot 32 and the card slot 33 are not inserted into the memory card, or when the card slot 32 is completely inserted into the memory card and the card slot 33 is not inserted, the LED 34 is lit. Alternatively, only the LED 36 may be lit. Thereby, power saving can be achieved.

  A cable release insertion unit 40 is provided below the card holding unit 30. As shown in FIG. 1, a release lid 41 that can be opened and closed is provided below the card lid 31.

  As shown in FIGS. 5 and 6, inside the release lid 41, a hollow cylindrical annular terminal (cable) in which a terminal pin of a cable release (release operation member for wired connection) (not shown) can be inserted and removed. A release insertion portion 42 is provided. That is, the annular terminal 42 has a right end opening 42B and a left end opening 42C, and is provided with a through hole 42A penetrating left and right. A boss 42 </ b> D that is inserted into the positioning hole 26 </ b> A of the main board 26 is provided on the outer surface of the annular terminal 42. The annular terminal 42 is positioned and fixed with respect to the main board 26 by inserting the boss 42D into the positioning hole 26A. A contact portion (not shown) connected to the main board 26 is provided on the outer surface of the annular terminal 42. By inserting a terminal pin of a cable release (wired connection release operation member) into the through hole 42A, the cable release and the main board 26 are electrically connected.

  An LED 43 is provided on the left side (the back side of the camera body 10) from the left end of the annular terminal 42 and on the front surface of the main board 26. In other words, the LED (auxiliary illumination) 43 is provided on the left side of the annular terminal 42 (the back side of the camera body 10) and avoiding the space virtually extending the through hole 42A. Thereby, the light leaking directly from the right end opening 42B of the through hole 42A to the outside of the camera body 10 can be reduced, and the user or the third person feels uncomfortable feeling such as entering the eyes of the user or a third party. Can be avoided. Further, since the inside of the through hole 42A and the right end opening 42B can be illuminated from the left end opening 42C side of the through hole 42A, the annular terminal 42 can be efficiently illuminated, and the visibility of the annular terminal 42 in the darkness can be improved. it can. As a result, the operability of the insertion / extraction operation of the terminal pin of the cable release to the annular terminal 42 in the dark can be improved.

  The light emitting surface of the LED 43 is covered with a diffusion sheet (diffusion member) 44 that diffuses the light emitted from the LED 43. Thereby, the inside of the through hole 42A and the right end opening 42B can be efficiently illuminated over a wide range. Here, the diffusion sheet (diffusion member) 44 does not necessarily need to cover the light emitting surface of the LED 43, and may be disposed between the light emitting surface of the LED 43 and the right end opening 42B, for example. In short, it is only necessary that the light emitted from the LED 43 can be diffused widely by the diffusion sheet (diffusion member) 44.

  As shown in FIGS. 1, 7, and 8, a front projecting portion 29 that projects forward is provided above the mount portion 11 on the front surface of the camera body 10. The left and right center of the front protruding portion 29 and the left and right center of the mount portion 11 substantially coincide. The front projection 29 is provided with an illumination unit 50. Specifically, the illumination unit 50 is on the right side of the left and right center of the mount unit 11 (left and right center of the front protrusion 29) in the left and right direction, in front of the mount unit 11 in the front and rear direction, and in the vertical direction. It is arranged on the upper side. The illumination unit 50 irradiates light downward.

  Specifically, the illumination unit 50 includes an LED (auxiliary illumination) 51 and a light distribution member 52 arranged with the light emitting surface facing downward. The light distribution member 52 is inclined so that the separation distance between the incident surface 52A disposed opposite to and substantially parallel to the light emitting surface of the LED 51 and the mount portion 11 is decreased as the light distribution member 52 moves backward from the incident surface 52A. And an emission surface 52B arranged in the same manner. The exit surface 52B is exposed to the outside of the camera body 10 through an exposure opening 53 provided on the right side of the left and right center of the front protrusion 29 and on the lower surface 29A of the front protrusion 29. The light distribution member 52 is made of a light transmissive resin, for example, and has a refractive index larger than that of air. For this reason, the light emitted from the LED 51 and reaching the emission surface 52B is refracted and emitted backward from the emission surface 52B, and illuminates the front surface of the camera body 10 (that is, the mount portion 11). Thereby, when the camera body 10 is viewed from the front, the user or the third party is given an unpleasant feeling such as the light emitted from the emission surface 52B entering the eyes of the user or the third party to feel dazzling. Can be avoided.

  In particular, the mount unit 11 can be positioned with the position of the lens side index of the camera lens (not shown) so that the user can visually recognize an appropriate mounting position between the camera lens (not shown) and the mount unit 11. An index 11A is provided. The mount portion side index 11 </ b> A is arranged on the right side of the left and right center of the mount portion 11. As described above, since the exposed opening 53 is also arranged on the right side of the left and right center of the front protrusion 29 (the left and right center of the mount portion 11), the mount portion side index 11A can be efficiently illuminated. As a result, the operability of the mounting operation of the camera lens (not shown) can be improved.

In the camera body 10, either the lighting mode or the extinguishing mode can be set for each of the LEDs (auxiliary lighting) 34, 36, 43, 51 and any combination thereof. . Among the LEDs (auxiliary lighting) 34, 36, 43, 51, the LED whose lighting mode is set is turned on when the lighting button 20 is pressed in the initial state, and is turned off when the lighting button 20 is pressed next time. Good. Alternatively, in the case where the lighting mode is set for the LEDs (auxiliary lighting) 34, 36, when the card cover (lid portion) 31 is opened, the LEDs (auxiliary lighting) 34, 36 are automatically lit. When the card lid (lid portion) 31 is closed, the LEDs (auxiliary lighting) 34 and 36 may be automatically turned off. Similarly, in the case where the lighting mode is set for the LED (auxiliary illumination) 43, when the release lid 41 is opened, the LED (auxiliary illumination) 43 is automatically illuminated and the release lid 41 is closed. Sometimes, the LED (auxiliary illumination) 43 may be automatically turned off. Alternatively, in the case where the lighting mode is set for the LED (auxiliary illumination) 51, when the interchangeable lens is detached from the mount unit 11, the LED (auxiliary illumination) 51 is automatically lit and replaced with the mount unit 11. When the lens is mounted, the LED (auxiliary illumination) 51 may be automatically turned off.
Further, when at least one of the card lid 31 is opened, the release lid 41 is opened, and the interchangeable lens is detached from the mount unit 11, the power supply of the camera body 10 is turned on. It may be turned off. For example, all of the LEDs (auxiliary lighting) 34, 36, 43, 51 may be lit for a predetermined time until the power is turned off, or when the card cover 31 is opened and the power is turned off. When only the LEDs 34 and 36 are lit and the release lid 41 is opened and the power is turned off, only the LED 43 is lit.
