The upper shielding plate 36 and the lower shielding plate 42
Is not provided, as shown in FIG.
52 is not formed. In this case, if the color of the background is the same as the color of the housing, it becomes difficult to distinguish the background image from the image at hand, and this gives a sense of incongruity to an observer (not shown) who views the image. . On the other hand, in the present embodiment, since the upper shielding plate 36 and the lower shielding plate 42 are attached, as shown in FIG.
The boundary line between them is photographed in black, and the shielding shadows 51 and 52 are formed. Therefore, the observer does not feel uncomfortable.

As described above, the tip of the lower shielding plate 42 is aligned with the boundary between the mirrors 14a and 14b,
In addition, since the setting is made so as to pass through the center of the optical axis of the lens 13, the thickness of the shielding shadow 51 can be made uniform.
In addition, if the bottom side is lengthened while keeping the inclination of the left and right sides of the triangle of the lower shielding plate 42 constant, the shielding shadow 51 can be made thicker. In this case, the lower shielding plate 42 has a shape close to a trapezoid.

As described above, in the present invention, since the angle of view of one lens 13 is divided and the face and hand of the user 21 are photographed, the face and hand of the user 21 can be captured with high resolution. Not only can images be taken, but also distortion (distortion) occurring in the images of the face and hands of the user 21 taken
Only the size can be reduced. In addition, since it is not necessary to use an ultra-wide-angle lens such as a fish-eye lens having a large angle of view as the lens 13, a normal lens can be used.
The cost of the monitoring camera device can be reduced.

Since the mirror 14 is provided below the optical axis of the lens 13, there is no obstacle above the lens 13. Therefore, the face photographing area 23 can be formed sufficiently wide, so that the user 21
Insert bills 19, passbooks, coins, etc. into respective insertion / exit outlets such as card insertion / exit 16, card insertion / exit 18, passbook insertion / exit 27, coin insertion / exit 28, etc .; Even when the user 21 takes out from the take-out slot, even if he gets on the automatic cash handling apparatus 10 side, the face of the user 21 does not fall out of the face photographing area 23 and the face of the user 21 can be reliably photographed. As a result, the operation of the user 21 can be sufficiently monitored.

Since the mirror 14 is formed by combining two flat mirrors 14a and 14b in a concave shape, the position of the face of the user 21 and the position of the image at hand can correspond to each other. . Therefore, the observer does not feel uncomfortable.

The angle of view B2 is made larger than the angle of view B1 by rotating the mirror 14 in the horizontal direction by changing the thickness of the spacers 34a and 34b.
5 can be larger than the image 46. Therefore, since it is not necessary to use mirrors having different sizes, the cost of the monitoring camera device can be reduced.

In the present embodiment, since the mirror 14 is made of glass, the mirror 14 is liable to be damaged when it is made thin.
Therefore, a mirror 14 having a certain thickness is required, but when the mirror 14 becomes thicker, as shown in FIG.
The shadow 52 becomes thicker and the angles of view A, B1, and B of the lens 13 become larger.
2 is reduced accordingly, and the face photographing area 23 and the first and second
The photographing areas 24 and 29 become narrow.

Therefore, the second aspect of the present invention in which the angles of view A, B1, and B2 can be increased, and the face photographing area 23 and the first and second photographing areas 24 and 29 can be widened. An embodiment will be described.

FIG. 9 is a perspective view showing a mirror according to the second embodiment of the present invention.

In the figure, reference numeral 14 denotes a mirror. The mirror 14 is mirror-finished by coating one surface of a plastic layer 57 with an aluminum plating layer 56 and bonding an adhesive tape layer 58 to the other surface. It is formed by doing. Therefore, the mirror 14 can be made extremely thin, and the mirror 14 is not broken and damaged. Further, since the mirror 14 can be attached to the mirror attaching plate 35 (FIG. 4) by using the adhesive tape layer 58 without using an adhesive, the workability of assembling the mirror 14 can be improved.

Next, a third embodiment of the present invention will be described. In addition, about what has the same structure as 1st Embodiment, the description is abbreviate | omitted by attaching the same code | symbol.

FIG. 10 is a perspective view showing a mounted state of a mirror according to the third embodiment of the present invention, FIG. 11 is a side view showing a mounted state of the mirror according to the third embodiment of the present invention, and FIG. FIG. 13 is a diagram showing an example of a background monitor image formed by the surveillance camera device according to the third embodiment of the present invention.

In the drawing, reference numeral 59 denotes one convex mirror as a photographing angle-of-view dividing means disposed on the back surface of the mirror attaching plate 35. The convex mirror 59 is formed by coating one side of a plastic layer having a convex shape (not shown) with a mirror finish by coating an aluminum plating layer (not shown), and bonding an adhesive tape layer (not shown) to the other side. And attached to the mirror attaching plate 35 via the adhesive tape layer. The convex mirror 5
9 constitutes a reflecting member that forms a convex surface downward.

In the surveillance camera device provided with the convex mirror 59 having the above configuration, when the background is photographed by the camera 11 (FIG. 4), a monitor image as shown in FIG. 13 is formed. In this case, since the convex mirror 59 is formed by one mirror, the hand photographing area 61 is not divided. Therefore, the observer can view the entirety of the images 47, 48, 49, and the like.

Since the convex mirror 59 is wider than the mirror 14 formed by combining the flat mirrors 14a (FIG. 2) and 14b in a concave shape, it is not necessary to divide the angles of view B1 and B2. Absent. Therefore, there is no need to provide a lower shielding plate.

It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified based on the gist of the present invention, and they are not excluded from the scope of the present invention.
