2. Description of the Related Art Generally, an opening is formed on one surface of a casing constituting the main body of a vending machine to take in and out products, and this opening is formed by a hinged door that can be opened and closed. Is covered.

On the other hand, in the above-mentioned vending machine, in order to prevent the theft of the goods housed in the housing which is the main body of the device,
A lock device is interposed between the opening and the door. The locking device is roughly classified into an engaging means for locking the housing and the door by engaging the peripheral edge of the opening of the housing with the peripheral edge of the door, and rotating by inserting a key. It is composed of an operating means composed of a key cylinder for engaging and disengaging the means.

By the way, when a vending machine (for example, a vending machine for telephone cards) is installed in a public telephone box with a small space, the vending machine can be installed on either the right side or the left side of the public telephone box. The configuration of arranging them close to each other is adopted. In that case, the key cylinder of the operating means is conventionally arranged on the front surface or the upper surface of the vending machine so that the key operation can be performed in either of the arrangement positions.

Further, conventionally, the above-mentioned engaging means of the lock device is arranged between the peripheral edge of the opening and the peripheral edge of the door except one side of the portion where the hinge for supporting the door is arranged.

[0006]

By the way, according to the above-described conventional locking device, since the key cylinder of the operating means is arranged in front of the vending machine, foreign matter such as a match stick is put in the key hole of the key cylinder. Not only is there a problem that mischief such as insertion is easily performed, but there is also a problem that the crime prevention is inferior because a drill or the like is easily inserted.

Further, in the case where the key cylinder of the lock means is arranged on the upper surface of the vending machine, the hand cannot reach the operator who is short, and the operability for locking and unlocking the door is poor. Not only that, since the keyhole faces upward, liquid such as dust or juice easily enters the keyhole, which causes a problem that the key cylinder is likely to be broken.

Further, according to the above-described conventional lock device, since the engaging means constituting the lock device is not provided at the portion where the hinge for supporting the door is provided, if the hinge is damaged. In the meantime, a device such as a bar is easily inserted and the door is easily opened, so that there is a problem that the crime prevention property is poor.

The present invention has been made in view of the above-mentioned circumstances. A first object of the present invention is to prevent a key cylinder from being mischievous, and moreover, a key operation by an operator is easy, and a vending machine is installed. Accordingly, it is an object of the present invention to provide a lock device for a vending machine, which can easily change the mounting position of the key cylinder.

A second object of the present invention is to provide an automatic vending machine capable of firmly maintaining the engagement between the housing opening and the door even when a part of the door is destroyed. The purpose is to provide a locking device for the machine.

[0011]

According to a first aspect of the present invention, there is provided a lock device for an automatic vending machine, which is provided between a peripheral edge of an opening of a casing which constitutes a main body of the automatic vending machine and a peripheral edge of a door which covers the opening. And the engaging means for engaging the
In a lock device for a vending machine having an operating means composed of a key cylinder for engaging and disengaging the engaging means, the operating means can be attached to both side surfaces of the housing. .

Further, in the second vending machine locking device according to the present invention, the engagement between the peripheral edge of the opening and the peripheral edge of the door which covers the opening constitutes the main body of the vending machine. In a locking device for a vending machine, which has an engaging means to be achieved and an operating means which is rotated by insertion of a key and which engages and disengages the engaging means, the engaging means comprises: The entire circumference of the opening peripheral edge and the entire circumference of the door peripheral edge are engaged with each other.

[0013]

In the lock device of the first vending machine described above,
Since the operation means can be attached to both sides of the casing that constitutes the main body of the vending machine, for example, in the case of a vending machine installed in a public telephone box, the vending machine is located on the right side of the public telephone box. If it is placed closer, the operating means should be attached to the left side of the housing, and if the vending machine is placed closer to the left side of the public telephone booth, the operating means should be attached to the right side of the housing. Often, when the operation means is attached to one of the side surfaces of the housing in this way, the key cylinder of the operation means is not arranged on the front surface or the top surface of the vending machine, and the key cylinder is damaged by mischief. In addition, the operability of the key by the operator is not deteriorated.

Further, according to the lock device of the second vending machine, since the engaging means engages the entire circumference of the opening peripheral edge and the entire peripheral edge of the door, the hinge supporting the door is damaged. However, the door of that portion is firmly engaged with the peripheral edge of the opening portion by the engaging means, and therefore even if a device such as a burl is inserted from the damaged hinge portion, the door cannot be easily pryed open. It will be.
