FIG. 1 is a circuit diagram of the first embodiment of the operation of the image storage function when a criminal cuts the cutting portion P of the wiring L of the CCD camera 2 (hereinafter referred to as cutting of the P portion). An operation flowchart of the vending machine with the anti-theft camera 2 will be described. In the normal operation, in step 100, the anti-theft device of the vending machine starts operating, and in step 101, the image signal picked up by the CCD camera 2 passes through the disconnection sensor 10 and is color-coded by the decoder 11. The signal is separated into a signal c and a luminance signal y, and the image data is compressed by the image compression unit 13. In step 102, the image data compressed as described above is stored in the RAM 14. Step 10

In step 104, the disconnection sensor 10, which determines whether the signal from the CCD camera 2 is normal or disconnected by the criminal based on the presence or absence of the synchronization signal, determines whether the synchronization signal is present. Proceed to step 105. In Step 105, the data stored in the RAM 14 in Steps 102 and 103 is transferred to the flash memory 16 to store the data.
Return to Steps 101 to 105 are constantly repeated at a high speed.

As shown in FIG. 5, each page stores the date, time, image data and sensor data stored in each page, and the page number of the flash memory 16 is stored every time steps 101 to 105 are performed. Is updated, and when the last page number is reached, the CPU 15 controls the address of the endless storage that returns to the first page number and updates the stored contents. Therefore, only the nearest past N pages remain as the memory, and the memory before that remains because it is updated.

Next, the operation of the storage unit 151 of the CPU 15 when the criminal cuts the wiring L of the CCD camera 2 will be described. In step 104, when the synchronizing signal from the CCD camera 2 disappears due to the disconnection of the P portion of the wiring L, the disconnection sensor 10 proceeds to step 107 in the N direction. Step 1

6 is prohibited, the flash memory 16 that has been stored is prevented from being overwritten and stored, and an operation that does not erase the criminal image is performed. Step 108 is the same as step 10
In response to the flow of 7, the buzzer 4 is sounded to warn that the criminal has cut the wiring L of the CCD camera 2.

In step 109, the memory update inhibition operation by the reset switch 31 of the setting switch 30 is released. Until the operation is released, the process proceeds in the N direction and the storage of the flash memory 16 is continued. When the reset switch 31 is closed, the memory update prohibition operation is cancelled, the system proceeds in the Y direction, and returns to step 101 in the initial operation state.

The contents stored in the flash memory 16 are as follows:
When the reproduction switch 32 of the setting switch 30 is closed and the storage of the flash memory 16 is returned to non-compressed data by the image expansion / contraction unit 17 under the control of the storage processing unit 151 of the CPU 15, a video signal is output by the encoder 18. Depending on the video equipment connected externally at
The image of the criminal who cut the CD camera wiring L can be confirmed, which can be used to determine the criminal.

Next, as shown in a second embodiment according to the flowchart of FIG. 3, the image data and the sensor data when the criminal performs an abnormal action and the sensor unit 3 is activated (hereinafter, referred to as abnormal sensor data). The storage operation will be described.
The steps 100, 101, 102, 103, 10
5, 106 normal operation and steps 107, 108, 1
Example when the P portion of the wiring L shown in 09 is cut off The operation is the same as that of FIG. Hereinafter, the operation of step 106 when the sensor data is abnormal will be described.

Step 106 is to output a signal based on the mischief situation by the sensor unit 3.
The output value of each sensor consists of an inclination sensor that detects a fall or a large inclination such as 0, a vibration sensor that detects kicking or impact, and a sound sensor that detects abnormal disturbance sounds or sounds such as disassembling the device. If the threshold exceeds a preset threshold value in the arithmetic processing unit 152, it is determined that the criminal has performed abnormal behavior, and the sensor data is determined to be abnormal, and the process proceeds to step 107 in the Y direction. As described above, the image storage and the sensor data of the criminal before the criminal commits the abnormal act can be stored, and can be used as evidence data of the criminal confirmation.

Next, a third embodiment will be described with reference to the flowchart of FIG.
A case where the sensor unit 3 is operated assuming that the criminal has performed an abnormal action together with the cutting action of the CCD camera wiring L by the criminal will be described. Steps 100, 101, 102, 10
Normal operation of 3, 104, 105, 106 and wiring L shown in steps 104, 106, 107, 108, 109
2 and 3 are the same as those in FIG. 2 and FIG. 3 and the description thereof is omitted, and the steps after step 108 will be described. Step 104A is for determining whether the sensor data is abnormal or the P portion of the wiring L of the CCD camera 2 has been cut, and prioritizes the storage processing. CCD before sensor data abnormality
If the P portion of the wiring L of the camera 2 has been cut, the process proceeds in the N direction and repeats in the N direction until the reset switch 31 is closed in step 109A, and does not perform the next work. That is, the storage update prohibition process in step 107 is continued, the data in the flash memory 16 is protected with the highest priority, and the storage in the flash memory 16 is not updated even if the sensor data abnormality occurs next. The image storage when the criminal cuts the P portion of the wiring L of the CCD camera and the storage of the sensor data can be used as evidence of the remaining criminal confirmation.

Next, in step 104A, if the sensor data abnormality occurs before the cutting of the P portion of the wiring L of the CCD camera 2, the process proceeds in the Y direction. Until the reset switch 31 is closed in step 109, the memory at the time of sensor data abnormality is always held. In step 104B, the disconnection of the P portion of the wiring L of the CCD camera 2 which always has a high priority of storage update is monitored, and if it is determined that the disconnection has been made, N is determined.
In order to proceed in the direction, the memory update prohibition is canceled in step 110 in order to store and update the image of the criminal at the time of disconnection in the flash memory 16 again prior to the sensor data abnormality, and then the process returns to the first operation and steps 101, 102, and 103 , 10
6, 104, 107, 108, 104A, and 109A are performed. As described above, when the line L of the CCD camera 2 is cut off by the culprit and the sensor data is abnormal, the image data and the sensor data are stored in the flash memory 16, and then the storage update is prohibited and the data is stored. Further, when the P portion of the wiring L of the CCD camera is cut after the sensor data is abnormal, the data can be updated by giving priority to the cutting. The above operation is not limited to vending machines, but a CCD camera is attached to a safe, such as a vault, and the criminal's face is converted into image data. Movement or damage is detected by the sensor unit and stored as sensor data, evidence of the criminal confirmation It can be.
