Embodiment An embodiment of the microcomputer rocker according to the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the microcomputer rocker 1 includes a plurality of rocker portions 2 each having a door 2a and a single input device 3 having a ten-key switch 5 (FIG. 2). The door 2a can be opened when the solenoid 18 (FIG. 4) provided inside the door 2a and constituting the locking device is energized. As is apparent from FIG. 2 showing an enlarged front view of the input device 3, an operation key 4 of an on / off contact type provided on the upper part of the input device 3 is operated by an administrator. The input device 3 is provided with a ten-key switch 5 for inputting a door number and a personal identification number, and light emitting diodes 7 to 11 as display devices for displaying operation states. In the input device 3 shown in FIG. 3, the ten-key switch 5 is arranged on the front surface which is formed to be inclined in order to improve the operability, and the operation key 4 is arranged on the surface which is erected from the inclined portion. The input device 3 can be configured in various shapes in consideration of design and the like.

FIG. 4 is a block circuit diagram of the control circuit of the microcomputer rocker according to the present invention. Various controls are carried out by a rocker control circuit 12 composed of a microprocessor. Operation key 4 on the rocker control circuit 12
And the output of the discrimination circuit 13 are supplied. Discrimination circuit 13
Discriminates the contents of the pressed ten-key switch 5 and supplies the discrimination output to the rocker control circuit 12. The contents of the discrimination circuit 13 discriminates the door number, secret number, personal identification number,
Numerical values and a specific code such as the # key for setting and the * key for clearing the setting. It is also possible to form the determination circuit 13 integrally with the rocker control circuit 12. The RAM 14 connected to the rocker control circuit 12 is used by the rocker control circuit 12 as a work area for a control program, a data save, a storage area for a personal identification number, a secret number, and the like. The ROM 15 connected to the rocker control circuit 12 stores a control program for the rocker control circuit 12. The locker control circuit 12 compares the input signal generated when the ten-key switch 5 is operated in a predetermined order with the personal identification number stored in the RAM 14, and unlocks the lock device when they match. Comparing means for generating a signal is provided. The RAM 14 of the rocker control circuit 12 is converted into the secret code reading mode when the secret number is input by the ten-key switch 5. Further, the read / comparing means provided by the program control provided in the locker control circuit 12 inputs the personal identification number with the ten-key switch 5 in the personal identification number reading mode, and when the personal identification number stored in the RAM 14 matches each digit, A drive output is generated every time. A plurality of light emitting diodes 8 constituting a display device
.About.11 are operated by the drive output of the reading and comparing means, and the user can recognize the correct personal identification number by operating the light emitting diodes 8-11. A driver circuit 16 connected to the rocker control circuit 12 drives a display device 17 including light emitting diodes 7 to 11 and a solenoid 18.

When setting the personal identification number in the RAM 14, as shown in FIG. 5, when the administrator operates the operation key in step S100, the door number can be input in step S101. The door number is generally input by a manager of a bank safe deposit box or a golf course locker locker, for example. If the door number is tilted, it is entered by entering a three-digit numerical value. Finally, the # mark on the ten-key switch 5 is entered to complete the entry of the door number. When the rocker control circuit 12 confirms that the # key is pressed in step S102, it is confirmed in step S103 whether the operation key 4 has been operated again. Generally, the re-operation of the operation key allows the user to input the door number in step S104 after the operation key 4 corresponding to the operation of removing the key is re-operated. Therefore, when the user of the locker unit 2 inputs the door number and the locker control circuit 12 confirms that the # key is pressed in step S105, the door number input by the administrator matches the door number input by the user. Step S1
Confirm with 06. The rocker control circuit 12 performs step S106.
If it is determined that the door number entered by the administrator does not match the door number entered by the user in step S104, the process returns to step S104 to prompt re-entry. The rocker control circuit 12 is step S106.
If it is determined that the number re-entered by the user is the correct door number in step S107, the personal identification number can be input in step S107. Here, the user inputs the secret code of a predetermined number of digits, and when the # key is finally pressed, the locker control circuit 12 confirms the input of the secret code and the # key in step S108. The setting is completed. Although not shown in FIG. 5, the light emitting diode 7 is turned on when the operation key 4 is operated, and the light emitting diodes 8 to 11 are turned on each time the personal identification number is input. The operation sequence and the display on the display device can be configured in various combinations, and the above is an example.

After that, when the user inputs the same number as the personal identification number from the ten-key switch 5, the comparison means of the rocker control circuit 12 causes the input signal generated when the ten-key switch 5 is operated in a predetermined order and the personal identification stored in the RAM 14. An unlock signal is generated when these numbers are compared with each other, and the unlock signal drives the solenoid 18 from the rocker control circuit 12 through the driver circuit 16 to unlock the lock device and the light emitting diode. The display device 17 composed of 7 to 11 is driven.

Next, if you forget your password or if you cannot unlock the lock device for the door 2a of the locker unit 2 due to an input error,
The administrator contacted by the user of the locker section 2 is
As shown in the figure, the operation key 4 is operated in step S200. Next, in step S201, RAM14 or ROM
Input the secret number stored in 15 through the tekey switch 5. The rocker control circuit 12 confirms whether or not the inputted secret number is a correct secret number (step S202). As a result, the rocker control circuit 12
After confirming that the correct secret number has been obtained, the RAM 14 is converted to the secret code reading mode for the current time, and a standby state is entered for inputting the # symbol for instructing the rocker control circuit 12 to start the secret code reading operation (step S203). The reading of the personal identification number and the registration of the personal identification number are performed according to a control program stored in the ROM 15 in advance. When the # key is pressed, control is transferred to step S204, and the door number can be input. When the user inputs the door number and presses the # key at the end of the door number input, and the rocker control circuit 12 confirms the door number input and the # key input in step S205, step S206
At, it becomes possible to input a personal identification number composed of, for example, four digits. When a four-digit personal identification number is input by the ten-key switch 5 in the personal identification number reading mode, the reading / comparing means generates a drive output for each digit when it coincides with the personal identification number stored in the RAM 14, and is stored. The 4-digit personal identification number is read from the most significant digit. The reading can be performed while listening to the numbers stored in the memory of the user. When the user is not awake at all, the keys are sequentially input from the number 1 key of the ten-key switch 5. If the pressed number and the personal identification number do not match, the light emitting diode 8 does not light. When the pressed number and the personal identification number match, the drive output of the reading and comparing means turns on the light emitting diode 8 (step S208), and it becomes clear that it is the first digit. Similarly, if you press the number keys 1 to 1,
The light emitting diode 9 lights up when the key corresponding to the second digit security code is pressed. When it is determined in step S209 that all the secret codes up to the fourth digit have been read, the reading operation ends. In this way, the correct personal identification number can be recognized by operating the light emitting diodes 8 to 11. It is also possible to execute a program for reading the secret number by inputting the manufacturer number recorded in the ROM 15 in advance as the secret number.

EFFECTS OF THE INVENTION As described above, according to the present invention, it is possible to easily operate with a single operation unit, the storage space is wide, and when the password is forgotten, the password can be read smoothly without resetting the password. There is an effect that a good microcomputer locker can be obtained.
