Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)

Fig. 1 is a perspective view of the self-service equipment. As shown in FIG. 1 , the self-service device 1 is provided with a card slot 100 , and a user can perform various transactions or inquiry operations by inserting a debit card or the like into the card slot 100 . In addition, in FIG. 1 and the following figures, the direction toward the user of the self-service device 1 is defined as the front, and the direction away from the user is defined as the rear. In addition, the front in the present invention coincides with the light emission direction of the light guide body 150 described later.

Fig. 2 is a perspective view of the card insertion port viewed from the front. As shown in FIG. 2 , an outer frame 110 and a cover 120 are provided in front of the card insertion port 100 . Wherein, the outer cover 120 is embedded in the outer frame 110 so as to be surrounded by the outer frame 110 . In addition, the outer frame 110 is made of a non-transparent material, and the cover 120 is made of a transparent material.

With such a structure, when the user observes the card insertion port 100 from the outside, the light emitted from the LED substrate described later provided inside the card insertion port 100 can illuminate the transparent outer cover 120 and cannot illuminate the non-transparent outer cover 120 . Box 110 is illuminated. In addition, in order to prevent the user from seeing the internal mechanism of the card insertion slot 100 , it is preferable to roughen the outer surface of the cover 120 .

3 is a perspective view of the card insertion port 100 viewed from the front with the outer frame 110 and the outer cover 120 removed, and FIG. 4 is a card insertion port viewed from the rear with the outer frame 110 and the outer cover 120 removed. 100 perspective view.

As shown in FIG. 3 , a light guide holder 130 is provided behind the outer frame 110 and the outer cover 120 , and the light guide holder 130 holds the outer frame 110 , the outer cover 120 , and the LED substrate 140 and light guide 150 described later. Wait. The light guide holder 130 has a box shape with one side open (opened on the front side), and the outer frame 110 and the cover 120 are provided on the light guide holder 130 so as to cover the opening side of the light guide holder 130 . In addition, the light guide holder 130 has a long and narrow opening on a surface (corresponding to a box-shaped bottom) facing the outer frame 110 and the cover 120 , and the card enters the inside of the self-service device 1 through the long and narrow opening.

In addition, as shown in FIG. 3 , the light guide body 150 is provided on the surface of the light guide body holder 130 facing the outer frame 110 and the cover 120 (corresponding to the bottom of the box shape) in contact with the light guide body holder. Section 130. Thus, the light guide 150 faces the outer frame 110 and the cover 120 with a space (inner space of the light guide holder 130 ) separated.

On the other hand, as shown in FIG. 4 , an LED substrate 140 is provided outside one side of the light guide body 150 . A plurality of LED light sources are installed on the LED substrate 140, and the light emitted from these LED light sources propagates and reflects inside the light guide body 150, and finally emits from the front surface (the surface facing the user side) of the light guide body, so that the outer cover 120 illuminated.

FIG. 5 is a front view of the card insertion port 100, and FIG. 6 is a cross-sectional view of the card insertion port 100 at line A-A in FIG.

In the conventional card insertion slot, in order to divide the cover evenly and fully illuminate it, it is necessary to install LED substrates on both sides of the light guide. The front side surface of the light body emits to illuminate the cover. If the LED substrate is only arranged on one side, the brightness of the outer cover will be uneven, and one side will be bright and the other side will be dark when viewed from the outside, which will affect the appearance and bring discomfort to the user. However, since the LED substrates are provided at both ends, the overall cost of the device increases, and it is difficult to reduce the size of the device.

On the other hand, in the card insertion slot 100 according to Embodiment 1 of the present invention, as can be seen from the cross-sectional view of FIG. Not set on the other side. In addition, in order to improve the light guide property of the light to the outside (user side), so that the light from the LED substrate 140 can be uniformly emitted throughout the longitudinal direction of the light guide body 150 (the left and right directions in the figure), in the The back surface of the light guide 150 is provided with an inclined surface 151 . Specifically, as shown in FIG. 6 , the side of the light guide plate 150 on which the LED substrate is not mounted (the right side in the figure) is closer to the side on which the LED substrate 140 is mounted (the left side in the figure). Front (user side). Thus, as shown in FIG. 7 , since the LED light source installed on the LED substrate emits parallel light along the left-right direction, the light is reflected by the inclined surface 151 of the light guide body 150 and uniformly emitted from the front surface 152 of the light guide plate 150, The housing 120 is thus evenly illuminated. That is, in the present invention, the inclined surface 151 serves as a light reflecting surface, and the front surface 152 serves as a light emitting surface.

In addition, the inclination angle of the inclined surface 151 of the light guide body 150 is not particularly limited, as long as the light emitted by the LED substrate can be uniformly reflected. In this embodiment, for example, the inclination angle of the inclined surface 151 of the light guide body 150 is set to 0° to 3°.

With the above configuration, the housing 120 can be evenly and sufficiently illuminated by disposing the LED substrate on only one side of the light guide plate 150 , and the cost can be reduced, and the overall size of the device can be reduced.

In addition, it is preferable that the end of the light guide plate 150 on the side where the LED board is not mounted is substantially aligned with the front-rear direction of the LED board, or is located behind the LED board.

In this way, the light emitted by the LED substrate 140 can be prevented from being directly blocked by the light guide 150 , and the light utilization efficiency can be improved.

In addition, there is no limit to the thickness of the light guide body, which can be properly set according to the actual needs of light guide. In addition, the thickness of the light guide does not have to be uniform, for example, it may gradually become thinner from one end to the other end.
