Abstract

PROBLEM TO BE SOLVED: To prevent an accident from occuring again by storing time at the time of opening a door by the portion of the number of using times and displaying the time data when necessary so as to confirm when and how often a third party excepting for the operating and managing person of a vending machine opens the door. SOLUTION: Whether the door is open or not is confirmed based on a detecting signal from a door switch part #6. At the time of confirming that the door is closed once after supplying power, the recording of the number of door opening times and its opening hour is started. Namely, when the door is opened, the opening hour of the door is stored by a door opening hour storing part #4 and the number of the door opening times is counted by a door opening frequency storing part #3. Then, whether the door opening frequency is recorded not less than ten times or not before is judged and when the opening frequency becomes not less than ten times, the opening times of the latest ten times are displayed on a door opening time display part #7 by the operation of a display switch part #10 or is printed out by a printer part #9 by key-inputting a keyboard part #8, while the older data is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine for recording the opening / closing status of a front door.

[0002]

2. Description of the Related Art A third party can open the door of a vending machine, open the door with an illegally obtained duplicate key, steal sales, or remove stored goods, thereby increasing sales. Control errors may occur in the vending machine when it does not match the actual sales amount or when the setting of the vending machine is changed without permission.

[0003]

In such a case,
The responsibility for the operation of the vending machine and the management of the manager (maintenance person) will be questioned, but since there is no evidence left, the operation and the manager suffer disadvantages such as disadvantages.

Accordingly, an object of the present invention is to provide a vending machine capable of clarifying the above-mentioned accident when it occurs, and preventing the recurrence of such an accident.

[0005]

A door switch is provided for detecting the open / closed state of a front door of a vending machine.
Therefore, a door opening time storage unit (# 4) that stores the time when the door switch is operated for a predetermined number of times, and a door opening time storage unit
The data of a series of times stored in (# 4) is displayed on the display unit (# 4).
7) a display switch section (# 10) for displaying.

[0006]

Since the door opening time storage unit (# 4) stores at least the predetermined number of time data, the display switch unit is used when the above-mentioned theft accident occurs.
By operating (# 10), a series of time data is displayed on the display unit (# 7). By referring to the data, it is possible to know when and how many times a third party other than the vending machine operator and the manager of the vending machine opened the door. If an abnormal operation occurs in the control, it can be used to investigate the cause.
In addition, by notifying that the history of the opening of the door is stored, the effect of preventing recurrence of the theft accident can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an internal outline of a vending machine showing an embodiment of the present invention. The following devices are provided inside the front door D. # 1 is a main controller for centrally controlling the vending machine. # 6 is a door switch for detecting the open / closed state of the door D. # 8 is a keyboard unit for setting and inputting various sales data and the like. # 9 is a printer unit that prints out sales data and the like and also prints out time data according to the present invention.

FIG. 2 is a control block diagram of the vending machine, in which the same elements as those in FIG. 1 are denoted by the same reference numerals. The main control unit # 1 has a clock unit # that measures the time.
2. A door opening frequency storage unit # 3 for storing the number of times the door D is opened, a door opening time storage unit # 4 for storing the time when the door D is opened, and an opening / closing signal from the door switch # 6. A door opening signal input section # 5 for sending out as a count signal to the opening number storage section # 3 is provided. # 7 is a door opening time display unit that displays the number of times of door opening and the door opening time obtained in the door opening number storage unit # 3 and the door opening time storage unit # 4, and is a display switch unit # 1.
It is displayed at any time by the operation of 0. The number of times the door is opened and the time at which the door is opened can be determined by operating the keys of the keyboard # 9.
Printed out to printer # 9.

The control operation of the vending machine will be described below with reference to the flowchart of FIG. When the power of the vending machine is turned on, the process proceeds from step S1 to step S2, and based on a detection signal from the door switch # 6, it is confirmed whether the door D is closed. Once it is confirmed that the door D is closed after the power is turned on, the process proceeds to step S3, and recording of the number of times the door D has been opened and the opening time thereof are started.

That is, it is determined in step S5 whether the door D has been opened. If the door D has been opened, the process proceeds to step S5, where the door opening time of the door D is stored in the door opening time storage unit # 4. The number of times the door D has been opened is counted in the door opening number storage unit # 3. In step S6, it is determined whether or not the number of times of opening of the door D has been recorded 10 times or more in the past. If the number of times of opening of the door D is less than 10, the process returns to step S3, and the counting of the number of times of opening of the door D is continued. When the number of times becomes 10 or more, the process proceeds from step S6 to step S7, where the latest one
Only the data for 0 times is left, and data older than that is deleted.

In the next step S8, the recorded data is output by the following means. That is, the latest ten opening times are displayed on the door opening time display part # 7 by operating the display switch part # 10, or the latest ten opening times are displayed on the printer part # 9 by key input of the keyboard part # 8.
The opening time of the batch is printed out

[0012]

As described above, according to the present invention, the time when the door is opened is stored a predetermined number of times, and the time data is displayed when necessary, so that the operation of the vending machine is performed. If a third party other than the administrator can know when and how many times the door has been opened, the data can be used to take measures to prevent the recurrence of the accident, and if an abnormal operation occurs in the control, Can also be used to find out. In addition, by notifying that the history of the opening of the door is stored, the effect of preventing recurrence of the theft accident can be obtained.
