It is issued as a release card that can unlock the state of a certain room, a spare card and a business card owned by the front desk clerk, and the card code number assigned to each card along with other data is written at the time of issuance It is.

 Next, the operation of this embodiment will be described.

First, when issuing a card in the card issuing machine 8, the magnetic card 1 is mounted on the magnetic recording means of the card issuing machine 8, and predetermined data is written. In this case, if it is a customer card, the hotel code number, the room number of the room to be used, the code number assigned to each of the individual storages 28a to 28d of the valuables storage 28, the card code number, the issue date and time and the effective date The date and time are recorded, and the arithmetic means built in the card issuing machine 8 calculates the room number and the date of issue using a predetermined relational coefficient, and records the numerical value as a password together with the data. The PIN is calculated in the same manner as described above using the member code number instead of the room number in the member card, and is assigned to the employee or the trader in the business card excluding the unlock prohibition card, the release card and the spare card. It is calculated using the code number instead of the room number. The unlocking prohibition card, the release card and the spare card use the room number for the calculation of the personal identification number, similarly to the customer card. In the embodiment, for example, the number indicating the date of issue is set to A, and the number of the room number or the member, employee or trader code number is set to B, and the number B obtained by squaring A is used as the method of calculating the password. The number C in the first digit is a password. Thus, predetermined data is written on the magnetic card 1 to produce various cards.

On the other hand, in the unlocking device 9, it is necessary to write initial data to the RAM 18 at the time of system start. Therefore, the data input device 10 is connected to the unlocking device 9 to write the initial data. Here, as the initial data, the hotel code, the room number of the room in which the unlocking device 9 is installed, the current time setting of the clock IC 17, the date and time of issuance of the guest card, the date and time of issuance of the maid card, The date of issue of the maintenance card, date and time, etc. If a program is provided in advance to set the initial setting data for each issue date and time to "0" at the start time, the issue year is automatically set at the time of the initial battery start-up as well as when the battery runs out. You can set the date and time. When the initial data is input from the data input device 10 to the unlocking device 9 and then the data input device 10 is removed, the magnetic card 1 can be unlocked thereafter.

Next, unlocking by the magnetic card 1 will be described based on a flowchart.

First, when the magnetic card 1 is inserted into the card reader 3,
The card reader 3 reads data magnetically recorded on the magnetic card 1 as shown in FIG. The read data is transferred to a changeover switch circuit 22, an I / O circuit 11, and a decoder 24.
Is input to the arithmetic and control circuit 15 through the control circuit and the data content is determined by the arithmetic and control circuit 15. Here, the arithmetic control circuit 15 determines whether the hotel code number in the data matches the hotel code number stored in the RAM 18, and if they match, from the card code number read next, It is determined whether the card is a customer card, a membership card, or a business card. The data read according to each card type is compared with the data stored in advance and the calculation to determine whether the card is valid or invalid. First, in the case of a customer card, comparison judgment is performed based on the flowchart shown in FIG. That is, first, the read issue date is compared with the issue date of the guest card stored in the RAM 18, and the issue date read from the magnetic card 1 is stored. If it is the same as or newer than the minute, it is determined to be valid, and the read valid date and time are compared with the current date and time and time measured by the clock IC 17 and the valid date and time are compared with the current time. If it is in the future, it is determined that it is valid, then the room number of the use object read next is compared with the room number stored in the RAM 18, and if they match or are included, it is further determined that it is valid.
It is determined whether or not 19 is in the unlocking prohibited state. If the unlocking is not in the unlocked state, the same as the calculation of the personal identification number performed by the card issuing machine 8 from the room number read from the magnetic card 1 and the issue date and time In the arithmetic control circuit 15, the arithmetic operation is performed, and the numerical value of the arithmetic result is compared with the password read from the magnetic card 1 to determine whether or not they match. If they match, the arithmetic and control circuit 15 determines that the used magnetic card 1 is a valid card for the unlocking device 9, and
A control signal for unlocking the latch bolt is output to the electric lock 19 through the decoder 25 and the I / O circuit 20 to unlock the lock. Also
The date of issue of the guest card stored in the RAM 18 is updated to the date of issue issued from the magnetic card 1 used, and the hotel code number, room number and card code read from the magnetic card 1 are updated. Each is written to a predetermined address of the RAM 18.

In the case of a member card, the date, time, and date of issuance read as shown in FIG. Is compared with the current date and time, and if the effective date and time is later than the current time, it is determined to be valid, and the next room number to be used and the room number stored in the RAM 18 are read. Is determined to be more valid if they match or are included, then it is determined whether or not the electric lock 19 is in the unlocking prohibited state. If not, the member read from the magnetic card 1 is determined. The calculation is performed in the calculation control circuit 15 in the same manner as the calculation of the personal identification number performed by the card issuing machine 8 from the code number and the date of issuance, and the numerical value of the calculation result is compared with the personal identification number read from the magnetic card 1. And compare for match judge. If they match, the arithmetic control circuit 15 performs the same control operation for unlocking as in the case of the customer card and updates the write data to the RAM 18.

Further, in the case of a business card, the type of the business card is determined by a type determination routine. If it is determined in this determination routine that the card is a maid card, the operation control circuit 15 reads the employee code number from the magnetic card 1 as shown in FIG. The issue date and time are compared with the issue date and time of the maid card stored in the RAM 18, and the issue date and time read from the magnetic card 1 is the same as the stored issue date and time or If it is new, it is determined to be valid, and the read valid date and time are compared with the current date and time measured by the clock IC 17 if the valid date and time are later than the current time. It is determined that the card is valid, then the room number of the use object read next is compared with the room number stored in the RAM 18, and if the room number matches or is comprehensive, it is further determined that the card is valid, and then whether the card is an unlocking prohibition card Judge whether it is an unlocking prohibition card. Then, the calculation is performed in the calculation control circuit 15 in the same manner as the calculation of the personal identification number performed by the card issuing machine 8 from the employee code number read from the magnetic card 1 and the date of issuance, and the calculation result and the magnetic card 1 Then, the password is compared with the password read from the device, and it is determined whether or not they match. If they match, the arithmetic control circuit 15 performs the same control operation for unlocking as in the case of the customer card and updates the write data to the RAM 18.

In the case where the magnetic card 1 is a master card or an emergency card, as shown in FIG. The effective date and time and the current date and time are compared with the current date and time, and if the effective date and time and date are later than the current time, it is determined to be valid, and then the employee code number read from the magnetic card 1 In the same way as the calculation of the personal identification number performed by the card issuing machine 8 from the date of issuance, date and time, the calculation is performed in the arithmetic control circuit 15, and the calculation result is compared with the personal identification number read from the magnetic card 1 and matched. Is determined. And if they match, the arithmetic control circuit
15 performs a control operation for unlocking.

If the magnetic card 1 is a maintenance / inspection card, the issuing date is read from the magnetic card 1 and the maintenance / inspection card stored in the RAM 18 as shown in FIG. Is compared with the date of issue of the magnetic card 1
If the issue date read from is the same as or newer than the stored issue date, it is determined to be valid, and the read effective date and time and the current date measured by the clock IC17 If the effective date and time and minute are later than the current point, it is determined to be valid, and the room number of the room to be read next and the room number stored in the RAM 18 are compared. If they match or are included, it is determined that the validity is further valid. Further, in the arithmetic control circuit 15 in the same manner as the operation of the personal identification number performed by the card issuing machine 8 from the trader code number read from the magnetic card 1 and the date of issue, date and time. The calculation is performed, and the calculation result is compared with the password read from the magnetic card 1 to determine whether or not they match. If they match, the arithmetic control circuit 15 performs the same control operation for unlocking as in the case of the customer card and updates the write data to the RAM 18.

In addition, when an employee performs maintenance and inspection on the maintenance and inspection person card, an employee maintenance and inspection person card is issued,
When this card is checked, the employee code number is read as well as the maid card, and the personal identification number is calculated based on the employee code number.

Next, in the case of an unlock prohibition card or a release card, the tenth
As shown in the figure, the issue time of the business card read is greater than the current time measured by the clock IC 17 and the effective date read from the magnetic card 1 is compared with the current date and time. If the effective date and time are later than the current time, it is determined to be valid, and the next read room number to be used is compared with the room number stored in the RAM 18 to find a match or inclusion. If it is valid, it is determined that it is still valid.
In step 15, the calculation is performed, and the calculation result is compared with the password read from the magnetic card 1 to determine whether or not they match. If they match, the arithmetic control circuit 15 sets the unlocking device 9 to the unlocking prohibition state or cancels the unlocking prohibition state, and updates the write data to the RAM 18 in the same manner as in the case of the other cards described above. Then, the room number of the use object read next is compared with the room number stored in the RAM 18, and if the room number matches or is included, it is determined that the room number is further valid. The calculation is performed in the arithmetic control circuit 15 in the same manner as the calculation of the personal identification number performed by the card issuing machine 8 from the date of issuance, date and time of the issuance, and the calculation result is compared with the personal identification number read from the magnetic card 1 to determine whether they match. Are compared. If they match, the arithmetic control circuit 15 sets the unlocking device 9 to the unlocking prohibition state or cancels the unlocking prohibition state, and updates the write data to the RAM 18 in the same manner as in the case of the other cards described above. Further, when the magnetic card 1 is a spare card, the room number to be used is read as shown in FIG. 11 and the room number stored in the RAM 18 is compared. If it is valid, the calculation is performed in the calculation control circuit 15 in the same manner as the calculation of the personal identification number performed by the card issuing machine 8 from the room number and the date of issuance, as in the case of the customer card. The personal identification number read from 1 is compared with the personal identification number to determine whether they match. If they match, the arithmetic and control circuit 15 performs an unlocking control operation.

FIG. 12 shows a flowchart of the operation of the unlock control, and the arithmetic and control circuit 15 determines whether or not a door shut-out detection signal indicating the closed state locked by the thumb turn of the door 12 is input from the electric lock 19 side. If the input card is not input and the card used is determined to be valid, a control signal for unlocking is output for 50 msec by a built-in timer to drive the latch bolt in the unlocking direction. Then, the control signal is reset, and then a door open / close detection switch (not shown) for detecting whether or not the door 12 is opened is turned on, that is, it is determined whether or not the door 12 is closed. If it is, start time counting and if the door open / close detection switch does not turn off within 5 seconds,
The arithmetic and control circuit 15 outputs a control signal for locking the electric lock 19 for 50 msec.
After the lock is output and locked, the reset is performed, and the unlock operation ends. When the door 12 is opened at the time of unlocking or within 5 seconds after unlocking and the door open / close detection switch is turned off, the locking control is not performed. Of course, when the door 12 is closed again and an ON signal of the door open / close detection switch is input, the arithmetic control circuit 15 performs a control signal for locking in the same manner as described above.

When the shut-out detection signal is input, unlock control is not performed if the card used is other than an emergency card, and unlock control is performed as described above if the card is an emergency card.

Next, unlocking in the valuables storage 28 in the guest room will be described. First, a code number is assigned to each of the individual storages 28a to 28d of the valuables storage 28, and if a maximum of four people are to board the guest room, each person has a storage 28 other than the room number.
A magnetic card 1 on which code numbers corresponding to a to 28d are recorded is prepared and handed over, and unlocking of electric locks 19a to 19d attached to doors 29 of individual storages 28a to 28d records corresponding code numbers. It can be performed only by the magnetic card 1.

Next, the unlocking of the valuables storage 28 shown in FIGS. 14A and 14B will be described with reference to the flowchart shown in FIG.
First, when the magnetic card 1 is inserted into the card reader 3a, the card reader 3a reads data magnetically recorded on the magnetic card 1 and, under the operation of the arithmetic and control circuit 15, communicates with the customer card according to the flowchart of FIG. If determined, the thirteenth
Whether the magnetic card 1 is valid or invalid is determined based on the flowchart shown in FIG. That is, the arithmetic control circuit 15 first compares the read issue date and time with the issue date and time of the guest card stored in the RAM 18, and stores the issue date and time read from the magnetic card 1. If it is the same as or newer than a certain issue date and time, it is determined to be valid, and the read effective date and time are compared with the current date and time and time measured by the clock IC17. If the minute is future than the present time, it is determined to be valid, and the room number of the use object read next and the room number stored in the RAM 18 are compared,
If they match or comprehend, it is determined that the electronic locks are more effective. Then, it is determined whether or not the electric locks 19a to 19d are in the unlocking prohibition state. If not, the room number read from the magnetic card 1 and the issuance are issued. In the same way as the calculation of the personal identification number performed by the card issuing machine 8 from the date and time, the calculation is performed in the arithmetic control circuit 15, and the numerical value of the calculation result is compared with the personal identification number read from the magnetic card 1 to determine whether they match. Is determined. If they match, the arithmetic and control circuit 15 determines that the used magnetic card 1 is a valid card for the unlocking device 9, and the individual storages 28a to 28d recorded on the magnetic card 1 together with the room number. Scan the code number of
