The vending machine 2 includes a plurality of product storage boxes 24 in which the same types of products 6 are stored. Inside the front door 4, an inner door 28 that opens and closes the entire opening including the product replenishment port 26 of each product storage unit 24 is attached. On the back surface 4b of the front door 4, there is provided a display input setting unit 30 for performing various settings of the vending machine 2 and displaying the setting state.

Further, the back surface 4b exposes the back surface (case back surface) 38c of the money amount display 1, the charge input unit 16, the back surface 16a of the refund lever 18, and the like. Cables (not shown) for connecting the amount display 1 and other devices (not shown) such as a power supply device, a control device, a coin processing device, etc. installed in the vending machine 2 are connected to the rear surfaces 1a and 16a.
FIG. 3 is an exploded perspective view of the money amount display 1. The monetary amount indicator 1 is configured as one unit in which a protective cover 32, a front cover 34, a printed circuit board (substrate) 36, and a support frame (housing) 38, all of which are rectangular, are sequentially stacked from the front side. .

The protective cover 32 is formed of a transparent resin material or the like, and constitutes one housing 40 for accommodating the front cover 34 and the printed circuit board 36 by engaging with the support frame 38.
The front cover 34 is composed of a printing sheet whose front surface 34a has a transparent character portion, the inside of the front cover 34 is appropriately perforated, and the display of each mounting part on the front surface 36a of the printed circuit board 36 is displayed on the front surface 34a. Appropriately displayed in each display frame.

The printed circuit board 36 has a front face 36a mounted with a monetary amount display section 42, a data communication section 44, other unsold lamps not shown, bill unusable lamps, change-out lamps, etc., and a rear connection face 46b for connection pins 46a A connector portion 46 having an IC chip, an IC chip, a speaker, etc. (not shown) are mounted.
The support frame 38 has a bottomed shape with a full front opening, and the printed circuit board 36 and the front cover 34 are sequentially accommodated from the front opening 38a.

On the back surface portion 38 b of the support frame body 38, support portions 48 are erected at heights that reach the middle of the depth direction of the support frame body 38 at the four corner portions. When the corners abut, the printed circuit board 36 can be positioned with respect to the support frame 38, and a space for exhausting heat from the printed circuit board 36 is secured between the printed circuit board 36 and the back surface 38b.
4 is a cross-sectional view of the support frame 38 in a state where only the printed circuit board 36 is accommodated, as viewed from the AA direction in FIG. The support frame 38 is formed to have a depth D, and three back openings (openings) for connecting cables to the three connector portions 46 for external connection are provided on the back 38c of the support frame 38. 50 is opened at a position corresponding to each connector portion 46.

When the support board 48 accommodates the printed circuit board 36 in the support frame body 38, the connector section 46 does not protrude from the back opening 50 to the outside of the support frame body 38, and a cable is connected to the connector section 46. It is formed at a height that does not hinder it.
FIG. 5 is a longitudinal sectional view of the support frame 38 in a state where only the printed circuit board 36 is accommodated, as viewed from the direction BB in FIG. On the back surface 38c of the support frame 38, a flange portion 52 is formed integrally with the back surface portion 38b by bending the upper end edge 50a of the back surface opening 50 over the entire area.

The flange portion 52 is connected to the inner inclined portion 54 inclined downward from the back surface 38 c toward the inner side of the support frame body 38, and the inner inclined portion 54, and the lower side toward the outer side of the support frame body 38. The outer inclined portion 56 is inclined to form a V-shaped cross section.
The lower end portion 56a of the outward inclined portion 56 is flush with the back surface 38c, and is formed with an acute cross-sectional shape in which the lower surface 56b of the lower end portion 56a is a horizontal plane.

  Here, when the front door 4 of the vending machine 2 is opened and closed, rainwater or the like adhering to the upper portion of the front door 4 scatters, and water droplets 58 as shown in FIG. 5 rarely adhere to the back surface 38c of the support frame 38. There are things to do. The water droplets 58 adhering to the back surface 38 c hang down the back surface 38 c by its own weight and reach the inward inclined portion 54. The flow rate of the water droplet 58 is reduced at the inner inclined portion 54 and flows down from the inner inclined portion 54 to the outer inclined portion 56. The water droplet 58 that has reached the outward inclined portion 56 is guided to the outside on the back surface 38c side of the support frame 38 at a low speed.

  Since the amount indicator 1 has such a collar portion 52, it is possible to prevent the water droplet 58 from entering the housing 40 from the back opening 50, so that the water droplet 58 hangs down on the connection pin 46a, or By reaching the printed circuit board 36 through the connector portion 46, it is possible to prevent the printed circuit board 36 from being short-circuited and spreading, and the reliability of the vending machine 2 can be improved.

  Further, since the flange portion 52 has the inwardly inclined portion 54, the flow velocity of the water droplets 58 that hang down the back surface 38 c can be reduced before reaching the outwardly inclined portion 56. It is possible to suppress the water droplets 58 that have reached to the outside from scattering on the back side 38c side. In other words, the water droplet 58 can be guided so as to hang down from the lower end portion 56 a of the outward inclined portion 56. Therefore, since it is possible to suppress water droplets from adhering to other devices existing on the back surface 38c side of the price display 1 in the vending machine 2, the reliability of the vending machine 2 can be further enhanced.

In addition, since the lower end portion 56a of the outward inclined portion 56 is flush with the back surface 38c, the dimension of the depth D of the money amount indicator 1 does not change even when the collar portion 52 is added. An effective waterproofing measure can be applied to the monetary amount display 1 without affecting the arrangement and dimensions of other devices existing on the back surface 38c side of the display 1.
In addition, since the lower end portion 56 a has an acute cross-sectional shape, the water droplet 58 guided by the outer inclined portion 56 flows down to the connector portion 46 along the rear surface of the flange portion 52, that is, the rear surface of the outer inclined portion 56. Can be suppressed. In particular, since the lower surface 56b is a horizontal plane, the flow of the water droplet 58 to the connector portion 46 can be more effectively suppressed as compared to the case where the lower surface 56b is an inwardly inclined surface.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, in the above-described embodiment, the flange portion 52 is formed to have a V-shaped cross section formed by the inner inclined portion 54 and the outer inclined portion 56, and an effective waterproof effect can be obtained with a simpler configuration. However, if at least the collar portion 52 has the outer inclined portion 56, it is possible to obtain a waterproof effect, and therefore the inner inclined portion 54 may not be present. Moreover, the collar part 52 is not necessarily limited to the V-shaped cross-sectional shape which consists of the inner inclination part 54 and the outer inclination part 56, You may employ | adopt various shapes.

  Moreover, in the said embodiment, although the lower end part 56a of the outward inclination part 56 is flush | level with the back surface 38c, you may make the lower end part 56a protrude a little from the back surface 38c. As a result, the water droplet 58 guided from the outward inclined portion 56 can be more reliably guided outward from the back surface 38c while the depth D of the support frame 38 remains almost unchanged. More effective waterproofing measures can be taken.

  In the above embodiment, the lower surface 56b of the lower end portion 56a is a horizontal plane, but the lower surface 56b may be an outwardly inclined surface inclined downward toward the outside of the support frame body 38. Thereby, the water droplet 58 guided by the outward inclined portion 56 flows down to the connector portion 46 along the back surface of the flange portion 52, that is, the back surface of the outward inclined portion 56, as compared with the case where the lower surface 56b is a horizontal plane. And it can suppress more effectively.

  Finally, although the money amount display 1 was demonstrated in the said embodiment, not only this but the display regarding the goods 6 is performed in the front surface 4a of the front door 4, a printed circuit board is accommodated, and the back is the back surface 4b of the front door 4. It is needless to say that the present invention can be applied to other display devices of the vending machine 1 as long as a housing having an opening for the connector portion on the back surface is provided.
