FIG. 11 is a flow chart showing the flow of the control operation in the security mode in the embodiment of the present invention.

When the information indicating that the maintenance door has been opened arrives from the door switch 1, the control circuit 3 presses the operation switches 4a and 4b and inputs the personal identification code during the time T seconds after the arrival of the signal. It is determined whether or not the password has been input, and if the personal identification code is not input, a sounding control signal is sent to the acoustic buzzer 2 to sound and generate an alarm.

When the personal identification code is input, the personal identification code registered in advance in the memory means 3a is collated with the input personal identification code, and if they do not match, a blowing control signal is similarly sent to the acoustic buzzer 2. And make an alarm. If they match, the sound control signal is prohibited from being sent to the sound buzzer 2 and the sound generation is stopped.

The display portion of the optical display 5 is constructed so that four numbers are displayed as shown in FIG. Normally, the clock time is displayed. In the secret code input mode, for example, if the secret code is "11", the display state of the optical display 5 is set by pressing the operation switches 4a and 4b for a predetermined time (for example, about 3 seconds), and the operation switch 4a is turned on. By pressing 11 times and operating switch 4b once, "11" is displayed and the input secret code is displayed.

Next, the common operation of the control circuit 3 in each setting mode will be described.

Each setting mode includes operation switches 4a and 4b.
By pressing 4c and 4c selectively or in combination, each mode is set, and if the setting was done before, the value is displayed blinking on the optical display 5, and the current time blinks for the time. Is displayed. The clock count continues even during setting, and if the setting mode is left for a predetermined time (about 3 minutes), the setting mode automatically ends. At this time, the changed data becomes valid, and if there is no change, the previous set value is held. When there is no need to correct the previous set value, the operation switch 4b is pressed once to move to the next setting, and the setting mode is released when all the settings are completed. The setting value is configured to be changed outside the crime prevention time, but if it becomes necessary to perform it within the crime prevention time for unavoidable reasons, it can be changed by inputting the personal identification code.

Here, the setting of each control mode will be described in detail.

First, as shown in FIG. 13, the setting of the personal identification code is performed by pressing the operation switches 4a and 4b for a predetermined time (for example, 3 seconds), and the control circuit 3 sets the mode of the personal identification code input. The optical display 5 is brought into a display state. Next, when the personal identification code to be set is input from the operation switch 4a and the operation switch 4b is subsequently pressed, the code is stored in the memory means 3a and set as the personal identification code.

With respect to the input operation from the operation switch 4a, the number is incremented each time it is pressed. For example, when the secret code is "11", it is pressed 11 times or continuously pressed to become "11". It can be done by stopping at. When the button is kept pressed for 1 second or longer, the count is incremented at a rate of 4 counts / second and the optical display 5 displays the count as shown in FIG. The secret code can be selected and set from 99 types from "01" to "99".

Next, the clock setting mode will be described.
FIG. 14 is a flow chart showing the flow of the clock setting operation in the embodiment of the present invention.

The control circuit 3 judges whether or not the setting of the above-mentioned personal identification code is completed, and if so, the present time of the built-in clock 3b is displayed on the optical display 5. For example, when the current time is 12:00, a display as shown in FIG. 15 is displayed.

When the clock is set, the control circuit 3 determines whether or not the operation switch 4a is pressed to stop the operation, and then the operation switch 4b is pressed. If the operation switch 4b is pressed, the clock setting mode is set.
When the operation switch 4a is pressed in this state and the digit of "hour" is set, the digit of "minute" is blinked to prompt the setting of the "minute" unit by the operation switch 4a and whether the operation switch 4b is pushed or not. To determine. If the operation switch 4b is pressed, "minute" is set, the personal identification code and the set time are alternately blinked a plurality of times (three times, for example), and then turned off.

Also in this time setting, every time the operation switch 4a is pressed, "hour" and "minute" are counted up and
Press and hold for more than 2 seconds to count up at a rate of 4 counts / second.

Next, the timer setting mode will be described. FIG. 16 is a flow chart showing the flow of the timer setting operation in the embodiment of the present invention. This timer setting means setting or changing the value for "T" seconds.

When the operation switch 4c is pressed for a predetermined time (for example, 3 seconds) while the operation switch 4a is being pressed, the control circuit 3 sets the timer value and makes the optical display 5 blink to input the timer value. Encourage. If already set, the set value is displayed. When the operation switch 4a is pressed and a predetermined timer value (for example, 5 seconds) is displayed, when the operation switch 4b is pressed, the timer value is stored in the memory means 3a and the setting is completed. At this time, the timer value set on the optical display 5 is blinked a plurality of times (for example, three times) and turned off to notify the completion of the setting.

In this embodiment, 01, 05, 10, 15, 20 are repeatedly displayed each time the operation switch 4a is pressed, and FIG. 17 shows an example in which the time is set to 5 seconds.

Next, the guard time setting mode will be described. FIG. 18 is a flow chart showing the flow of the guard time setting operation in the embodiment of the present invention.

When the operation switch 4b is pressed and the operation switch 4c is pressed for a predetermined time (for example, 3 seconds), the control circuit 3 sets the security time setting state and blinks the optical indicator 5 to the setting state. Notify that it has become.
If the guard time has already been set, the set value is displayed.

In this embodiment, the security start time is 23:00,
When the security end time is 5 o'clock, the numbers 0 to 23 are counted up at a speed of 4 counts / second by continuously pressing the operation switch 4a, and when 23 is displayed on the display part of the security start time. When stopped and the operation switch 4b is pressed, the security start time of 23:00 is set, and the display section of the security end time of the optical display 5 blinks. Then, by pressing the operation switch 4a, the security end time will be displayed in the same way.
When the operation switch 4b is pressed when the guard end time is displayed at 5 on the display, the guard end time is set and the optical display 5 blinks a predetermined number of times (for example, 3 times) and goes out. The display example is shown in FIG. If the security start time and security end time are set to the same value, 24-hour security is enabled.

In this way, the secret code setting, the clock setting,
When the timer setting and the guard time setting are completed, the control circuit 3 sets the guard mode according to these set values. When the security mode is set, security time (for example, 23
When the maintenance door is opened from 0 to 5 o'clock and the timer setting time T seconds (for example, 5 seconds) elapses, the control circuit 3 sends a sounding control signal to the acoustic buzzer 2 to sound it. The secret code is input within the timer setting time T seconds, and the memory means 3
When it matches the code stored in a, the sending of the sound control signal to the acoustic buzzer 2 is prohibited and the sound is stopped.

For inputting the personal identification code, a ten-digit number is input by pressing the operation switch 4a a required number of times, and a one-digit number is input by pressing the operation switch 4b a required number of times. For example, when the secret code is "13", the input is made by pressing the operation switch 4a once and the operation switch 4b three times. When the timer setting time T seconds is exceeded when the personal identification code is input, the acoustic buzzer 2 sounds, but if the input personal identification code and the code stored in the memory unit match, a predetermined time (for example, 2 seconds later) 2) Sound buzzer
Stops blowing.

When the maintenance work is closed after the predetermined work is completed, the control circuit 3 receives the signal from the door switch 1 and sets the security mode again.

When the maintenance door is opened within the guard time, the optical display 5 displays the present time for a predetermined time (for example, 10 seconds) and then switches to the display of "00". However, if the personal identification code is input during the current time display, the personal identification code is displayed. When the input of the secret code is wrong, it can be input again while the display of the optical display 5 returns to the display of "00". There is no limitation on the number of times, and in the case of an erroneous input, the display on the optical display 5 returns to "00" after a predetermined time (for example, 2 seconds).

The embodiment of the present invention is provided with a battery check function, and if the acoustic buzzer 2 sounds when the operation switch 4c is pressed, it is not necessary to replace the battery.
If it doesn't blow, it needs to be replaced. The operation of this battery check is limited to the outside of the guard time, and even if the operation switch 4c is pressed for battery check in each setting mode, the acoustic buzzer 2 does not sound.

The operation of the door switch 1 provided on the maintenance door can also be checked, and when the door switch 1 is switched from off to on or from on to off, the optical display 5 displays a predetermined time. If the current time is displayed (for example, for 10 seconds), there is no abnormality, and if there is no such display, it can be known that there is an abnormality. If the operation switches 4a, 4b, and 4c are input within this predetermined time, the operation is preferentially performed.

Further, when the control circuit 3 runs out of control due to the voltage drop of the battery and noise, all the functions are stopped to prevent erroneous operation. The function can be released by resetting or replacing the battery.

[0046]

As described above, according to the present invention, when the maintenance person opens the maintenance door and inputs the personal identification code, the buzzing of the acoustic buzzer is stopped and the maintenance person opens the person other than the maintenance person who does not know the personal identification code. When it is hit, there is an effect that a buzzer sounds with a loud sound and an alarm is issued to notify that an abnormal state has occurred. In the device of the present invention, even if the maintenance door is opened by using the duplicate key, the audible alarm is sounded if the personal identification code is not input. And the code can be changed by a simple operation. In addition, it is possible to prohibit the sound buzzer from ringing during the hours when the clerk is working,
Even if the maintenance door is opened while the power is off, the acoustic buzzer can be audible, and further, it can be easily installed in the existing vending machine later.
