DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine safe installed in a vending machine for beverages, cigarettes, etc., for storing sales proceeds.

[0002]

2. Description of the Related Art In a vending machine of this type, a collection and delivery person periodically collects sales proceeds. Then, as shown in, for example, JP-A-8-287341, in order to prevent the collector / distributor from improperly dressing the sales proceeds, the sales proceeds storage box is made to be a safe with a key and collected together.
The recovered safe is unlocked by a trusted custodian and the proceeds are withdrawn. After this, the safe is reset to the vending machine.

[0003]

There are two ways to take out the sales money: a type in which the cash is taken out from a deposit port of the safe, and a type in which the upper case of the safe is taken out.

In the former type, when the safe is removed from the vending machine, the deposit port is usually closed by a shutter biased by a spring or the like. For this reason, when taking out the sales proceeds from the deposit opening, it is necessary to hold down with a finger so that the shutter does not close, and the work of removing the sales proceeds is troublesome. Also, as shown in, for example, Japanese Patent Application Laid-Open No. 8-287341 (paragraph number 0035), a special operation is required to make a safe re-settable in a vending machine, and it can be easily performed by anyone. It was not something.

[0005] On the other hand, in the latter type, although the work of taking out the sales proceeds is easy because the lid is detached,
As the number of parts increases, the image becomes vulnerable as a safe. In addition, a key for removing the lid and a tool for opening the shutter for closing the deposit opening so that the safe can be reset in the vending machine are separately required. In addition, when the manager actually collects the sales proceeds, it processes a large amount (10 units) at a time. Therefore, instead of opening and closing one safe at a time, the entire safe is opened once and then the sales are taken out. It is common practice to close everything and make it resettable. At this time, there was a problem that it was difficult to place the removed lid.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to operate a key so that a shutter can be kept open and a vending machine can be reset. Vending machine safes that can
