Description

[Detailed description of the invention] (b) Industrial application fields The present invention relates to a room entry control device.

(B) Prior Art Conventionally, as a device of this kind, there is a device that reads the recorded contents from a verification medium such as a card, and verifies the validity of the read contents to release the door lock and enter the room. Are known.

(c) Purpose of the Invention The present invention provides such a room entry control device that prints and magnetically records entry information, and further manages the accumulation of information in the device for magnetic recording, thereby tallying the actual number of room entries. The purpose is to make management easier.

(d) Configuration of the Invention The room entry control device of the present invention includes a reader section that reads recorded contents from a verification medium such as a card, a verification section that verifies the validity of the contents read by the reader section,
a door lock driving section that drives the door lock based on the output signal of the collation section; an entry information generating section that generates room entry information based on the content read by the reader section; a magnetic recording device that magnetically records the room entry information; An instruction section that instructs the amount of information stored in the magnetic recording device, a message output section that outputs a message corresponding to the amount of information stored based on the instruction output of the instruction section, a printing device, the room entry information generation section, and a message output. a printer control circuit that sends the output contents of the copy to the printing device for printing on the printing device; and a printer control circuit that prohibits new information storage in the recording device when the amount of information stored by the instruction section is a specific value. It is equipped with a prohibition circuit.

(E) Example The apparatus of this example is shown in the figure. In order to prove the validity of the person entering the room, the person entering the room carries a card 1 with a code unique to the person entering the room, and when entering the room, inserts the card 1 into the reader section 2 installed near the entrance, and the contents of the card are read. , that is, the unique code is read by the reader section 2. In the matching section 3, the matching circuit 4
searches the individual unique codes of many people entering the room stored in the memory circuit 5, and reads the reader part 2 among them.
When it finds the unique code signal A output from the controller, it outputs the signal B. This signal triggers the monostable multi-circuit 6 and generates the unlocking signal C for a certain period of time, and the door lock drive section 7 receives the unlocking signal C. During that time, the electric lock 9 of the door 8 is released and entry is permitted. create a state.

On the other hand, the unique code signal A output from the reader section 2
is also included in the room entry information generator 10, and when the output signal B of the collation section 3 arrives, the generation section generates room entry information D consisting of the name of the registrant, the current time, and the current number corresponding to the unique code signal. or gate 1
1, and the printer control circuit 12 causes the printing device 13 to print the entry information.
The entry information D further enters the magnetic recording control circuit 19 via the normally open AND gate 18.
This circuit records room entry information D using a magnetic recording device 20 such as a blotting device. Such magnetic recording is used for mechanically tallying room entry information by subjecting the recording medium to a counting machine or the like. Note that the structure of the room entry information is not limited to that described above; for example, only the name of the corresponding registrant may be used.

The instruction section 14 is composed of a counter, and the verification section 3
Each time the output signal B is received, its contents are incremented by one. The count upper limit value of the instruction section 14 is matched with the storage capacity of the magnetic recording device 20.
4: The count contents are 80%, 90% and 90% of the upper limit value.
At 100%, output signals E, F, and G are output, respectively. When the count content of the instruction unit 14 reaches the upper limit value, the content of the upper limit value is not changed even if there is a count input by the signal B, and the signal G continues to be output. This upper limit value state of the instruction section 14 is reset to the initial value by operating the switch 16.

After the room entry information generating section 10 completes outputting the room entry information D, it sends a signal H to the message output section 15. When the second editing section 1 inputs the signal H, if the instruction section 14 indicates that the signals E and F contain G,
“80%”, “90%” or “FULL” depending on each
character data I is output and sent to the printer control circuit 12 via the OR gate 11. Therefore, these character data are printed by the printing device 13.

Here, each time there is a valid entry into the room, the information of each person entering the room is sequentially printed by the printing device 13 and magnetically recorded by the magnetic recording device 20. Furthermore, the instruction unit 14 monitors the amount of room entry information accumulated in the magnetic recording device 20, and the amount of accumulated information is 80.
%, 90%, or 100%, the characters 80%, 90%, or FULL are printed next to the corresponding entry information.

Normally, in the case of the magnetic recording device 20, when the recording storage capacity is full and recording data is subsequently input, such new data is written to the already recorded data area, and the new data is written to the previously recorded data area. The previous data will be deleted. Therefore, when the storage capacity is full, it is necessary for the operator to immediately replace the magnetic recording medium, but as mentioned above, by printing out the storage capacity, it is possible to know for sure when it is time to replace the magnetic recording medium. can.

Furthermore, in the case of this device, the signal G of the instruction section 14
enters the AND gate 18 via the inverter 17 which together with the AND gate 18 constitutes a prohibition circuit. Therefore, when the accumulation amount reaches 100%, the subsequent entry information D to the magnetic recording device 20 is Writing is prohibited, and the contents of the magnetic recording up to that point are preserved. This procedure takes into account the case where the magnetic recording medium is not replaced even after it is full. On the other hand, even if writing to the magnetic recording device 20 is prohibited in this way, as is clear from the above explanation, subsequent room entry information will be printed, and the word "FULL" will be written on each print. Therefore, the record remains in a state where it can be determined as room entry information that is not magnetically recorded.

(F) Effects of the Invention According to the present invention, in a device that reads the recorded content from a verification medium such as a card, and verifies the validity of the read content, the door lock is released and entry is permitted. Since room entry information is printed and magnetically recorded, it is easy to aggregate and manage entry records, and the amount of information stored in the magnetic recording device is printed, and the amount can be set to a specific value. When the magnetic recording device becomes obsolete, new information storage in the magnetic recording device is prohibited, so the operator can replace the magnetic recording medium in a timely manner according to the printed information storage message.
Furthermore, even if the time for replacement is missed, the already recorded contents will not be destroyed, making it easier to manage the device itself.
