  Further, as shown in FIG. 1, a lower strobe unit S1 and an upper strobe unit S2 for photographing are provided at the front position of the user P on the surface of the open / close door 21 on the storage space 20B side. Furthermore, at the upper end of the back surface 36 in the photographing space 20A, an additional strobe unit (additional illumination unit) that emits light downward from above to the back surface 36 located at the rear position of the user P sitting in the seat 25 ) 40 is provided. The additional strobe unit 40 does not necessarily have to be provided at the upper end of the back surface 36, and the additional strobe unit 40 may be located above the user P sitting on the seat portion 25.

  The lower strobe unit S1 and the upper strobe unit S2 provided in front of the user P and the additional strobe unit 40 synchronously emit light at the light emission timing and the light emission amount instructed from the control unit 11.

  Next, the additional strobe unit (additional illumination unit) 40 will be further described. The additional strobe unit 40 illuminates the back surface 36 to suppress the shadow of the user P who is reflected on the back surface 36 by the lower strobe unit S1 and the upper strobe unit S2.

  Such an additional strobe unit 40 is provided at the upper end of the back surface 36 as described above, and a plurality of, for example, four light guide plates 41 extending parallel to the back surface 36 are installed at the lower end of the additional strobe unit 40 There is. The four light guide plates 41 guide the light from the additional strobe unit 40 to the back surface 36 side.

  Further, the height h of the four light guide plates 41 gradually increases as they are separated from the back surface 36 (see FIG. 2). Further, the upper ends of the respective light guide plates 41 coincide with the lower end of the additional strobe unit 40 and are positioned at the same height. Therefore, the lower ends of the four light guide plates 41 are positioned gradually downward as they are separated from the back surface 36.

  Therefore, the light emitted from the additional strobe unit 40 is guided to the back surface 36 side by the four light guide plates 41, and the light emitted from the additional strobe unit 40 flows into the photographing space 20A by the four light guide plates 41. You can prevent that.

  By the way, the backrest 45 for the user P is attached below the additional strobe unit 40 in the back surface 36, and the projection height h1 of the backrest 45 from the back surface 36 is the light guide plate 41 most distant from the back surface 36. It is larger than the distance h 2 from the back surface 36.

  For this reason, the light emitted from the additional strobe unit 40 is not guided by the light guide plate 41 inward from the backrest 45 with respect to the back surface 36. For this reason, this light does not illuminate the head or shoulder of the user P leaning on the backrest 45 from above, and the head or shoulder of the user P is excessively illuminated and the photograph taken of the user P is unclear. It will never be.

  In the embodiment described above, an example is shown in which the four light guide plates 41 extending in parallel with the back surface 36 are provided at the lower end of the additional strobe unit 40. It may be provided to be inclined to the 36 side.

  Next, the operation of the present embodiment having such a configuration will be described.

  During normal operation, the user P who is the subject enters the housing 20 and sits on the seat 25. The user P operates the monitor 14 along the screen of the monitor 14. When the user P charges the necessary fee to the charging facility 23, the lower strobe unit S1 and the upper strobe unit S2 and the additional strobe unit 40 operate in synchronization, and the camera 12 starts shooting. The image taken by the camera 12 is sent to the control unit 11, the photographic print is produced by the printer 17, and the produced photographic print is discharged from the outlet 20C.

  During this time, the user P who sits in the seat 25 may have a pigtail hair and a long back hair P1. For example, when the additional strobe unit 40 is installed in the backrest 45 and the back surface 36 is illuminated by the additional strobe unit 40, it is conceivable that the shadow of the long back hair P1 is reflected on the back surface 36.

  On the other hand, according to the present invention, the additional strobe unit 40 is provided at the upper end of the back surface 36, and the additional strobe unit 40 irradiates the back surface 36 from the top to the bottom. Therefore, the light from the additional strobe unit 40 is not blocked by the back hair P1, and the back surface 36 can be illuminated with certainty. In this case, the light from the additional strobe unit 40 can be reliably guided to the back surface 36 by the light guide plate 41.

  In this manner, the shadow 38 of the user P reflected on the back surface 36 by the lower strobe unit S1 and the upper strobe unit S2 can be reliably suppressed by the light from the additional strobe unit 40. Therefore, when the image taken by the camera 12 is sent to the control unit 11 and the control unit 11 performs the chroma key composition process with the image of the user P as the background 36, the chroma key composition process is appropriately and accurately performed. Can.
