DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1A is a schematic view of an autochanger type recording medium device according to an embodiment of the present invention as viewed from above.
FIG. 1B is a front view of a front door portion of an automatic changer type recording medium device according to an embodiment of the present invention. FIG.
In (a) and (b), a detachable front door portion 2 is attached to the front surface portion of the cabinet 1. Then, on both sides of the reproducing section 3 and the reproducing section 4 provided in the central portion of the cabinet 1, disk storage sections 5 and 6 for storing a plurality of disks are provided. The disc 7 is taken out from the plurality of discs accommodated in the disc accommodating units 5 and 6 by the transport unit 8 and placed on the reproducing unit 3 or the reproducing unit 4 for reproduction. Further, when the reproduction is completed, the disc 7 is picked up by the transport unit 8 and used as a storage unit.

When the transport unit 8 moves to the front of the cabinet 1, the projection 10 provided on the transport unit 8 contacts the mechanical unit 12 interlocking with the key unit 11 of the front door unit 2 so that the lock of the key unit 11 can be released. I have to. At this time, it is possible to open the 11 locks that are mechanically prevented from unlocking by metal fittings or the like. Further, the front door portion 2 is provided with a push button type switch 13 and a display portion 14 composed of a light emitting diode, and the display portion 14 indicates the operating state of the switch 13. The display unit 14 indicates the operation mode by changing the color of the light emitting diode, and indicates the digit of the personal identification number by changing the blinking interval of the light emitting diode. The display unit 14 may be a display device such as a liquid crystal display.

The front door section 2 and the switch 13 send an electric signal to the control section 9 by pressing a switch section (not shown) provided on the cabinet side with the switch 13.
The display unit 14 is connected to the cabinet 1 side by a contact (not shown) that is electrically conductive. Therefore, the front door part 2 can be removed and an electric signal can be sent to the control part 9. The reproducing units 3 and 4, the transport unit 8, and the display unit 14 are
It is controlled by the control unit 9 including a microcomputer. Further, the control unit 9 includes a circuit unit of the switch 13,
An input monitoring circuit, a data storage unit, a personal identification number comparison circuit, a control circuit of the display unit 14, and a display circuit showing the input digit of the personal identification number are provided, and the processing associated with the input of the personal identification number is performed. The memory 15 provided in the control unit 9 stores the number of times the switch 13 is pressed.

FIG. 2 is a flow chart showing the operation of the automatic changer type recording medium device according to the present invention. In FIG. 2, first, the control unit 9 is set to the personal identification number setting mode for unlocking the key portion of the front door unit 2, or
Alternatively, it is detected whether or not the personal identification number registration mode in which the personal identification number is registered (ST1). In ST1, the above two modes may be switched by a DIP switch or the like. For example, in the personal identification number registration mode in which once the setting operation is performed, the operation is hardly performed thereafter. When the power is turned on while pressing the switch 13, the switching mode setting switch is newly added to the front door section 2. It is possible to switch without providing. Normally, when the power is turned on, the process of the personal identification number setting mode is performed, and therefore the process proceeds to ST2.

The processing in the personal identification number setting mode will be described below. When the switch 13 is pressed (ST2), the control unit 9 detects the pressing time, for example, when it is pressed for a predetermined time (t) of 5 to 10 seconds (ST3),
The digit of the personal identification number to be set is displayed (ST4). The PIN code is usually 3 digits. When displaying the ones digit, the display unit 14 is blinked at intervals of about 1 second, when the tens digit is indicated, it blinks about twice per second, and when the hundreds digit is indicated, about three times per second. By blinking, the digit of the set personal identification number is indicated. Therefore, the registered digit can be displayed by one light emitting diode of the display unit 14.

When the display unit 14 displays the ones digit, when the switch 13 is pushed (ST5), the number of pushes is counted (ST6). Then, it is determined whether or not a predetermined time in the personal identification number setting mode has elapsed (ST7). If not, the monitoring time for setting the personal identification number is counted down (ST8), and the processing from ST5 is performed again.
When the display unit 14 displays the ones digit and the number of times the switch 13 is pressed is counted by the control unit 9 and a predetermined time elapses (ST7), the counted number is stored in the memory 15 as the ones code number. (ST11). Then, for example, until the 3-digit personal identification number is input (ST12), S
The processing from T4 is repeated. When the tens digit is set after the ones digit, the display section 14 is blinked twice per second, and the hundreds digit is blinked three times per second, and the digit of the personal identification number is displayed. It ensures that you can enter the PIN code for each digit. When the switch 13 is not pressed in the process of ST5, the countdown of the predetermined monitoring time in the personal identification number setting mode is started (ST9), and it is monitored whether or not a predetermined time has elapsed (ST10), and the predetermined time monitoring is performed. Then, the processing shifts from ST2.

FIG. 3 is a diagram showing the timings of the switches and the display section of the automatic changer type recording medium device according to one embodiment of the present invention. The waveform diagram on the upper side of FIG. 3 shows the pulse signal generated when the switch 13 is pressed, and the waveform diagram on the lower side shows the presence or absence of display on the display unit 14. To open and close the front door part 2, if the switch 13 is pressed and kept pressed for a predetermined time from the rise of the pulse, the operation is started after t1.
Display the digit of the PIN code setting of 4. At this time, the display unit 1
4 lights up. In the present invention, as described above, the number of blinks of the display unit 14 in a predetermined time is changed for each digit for display. The control unit 9 detects the rising signal of the pulse within the time t2 when the display unit 14 is lit. Here, it is indicated that the switch 13 has been pressed four times, and the personal identification number is 4. During t3 after the lapse of t2, even if the display unit 14 is turned off and the switch is pressed, the counting is not performed.
The PIN code setting mode ends. After the elapse of t3, the next digit is processed. When the reproducing unit 3 or 4 is reproducing the disc 7 and nothing is pressed within the time t2, it is determined that the operation is mistaken and the reproduction is continued. In FIG. 3, switch 1
Although the pulse signal when 3 is pressed is set to the high level (H), the same processing can be performed when the pulse signal is set to the low level (L).

When all the predetermined three digits of the personal identification number are set, the personal identification number setting mode is confirmed (ST13), and if the personal identification number setting mode is selected, the personal identification number registered in the memory 15 is compared. (ST14) If the two match, a disc return process is performed (ST15). The disc 7 placed on the reproducing unit 3 is accommodated in the disc accommodating unit 6 by the conveying unit 8 along the arrows A to B in FIG. Then, a display indicating the end of the disc return is displayed on the display unit 14 (ST16). At this time, the transport section 8 has moved to the front surface of the front door section 2 and can unlock the key section 11 (ST14). If the personal identification numbers do not match, the process starts from ST2 again, and the personal identification number setting is restarted from the first place.

Next, the personal identification number registration mode will be described. When the control unit 9 detects in ST1 that the registration mode is a personal identification number, the display color of the display unit 14 is changed from green to red, for example, to notify the mode (ST17). Then, the digit to be registered is displayed in order to register the personal identification number. First of all, it is the first place. At this time, the display unit 14 is changing the blinking interval between the tens digit and the hundreds digit as in the case of the personal identification number setting mode. The operation of repeatedly inputting up to a predetermined digit is the same as that of the personal identification number setting mode, and therefore its explanation is omitted. At this time, the number of each digit is stored in the memory 15 (ST11). The memory 15 is a non-volatile memory and holds the data of the personal identification number even after the power is turned off. Memory 1
Since 5 is provided in the control section 9 on the cabinet 1 side, the personal identification number is retained even if the front door section 2 is removed.
When the personal identification number is stored up to a predetermined digit (ST12), it is determined in ST13 whether or not the personal identification number registration mode is set. When it is determined that the personal identification number setting mode is set, the display color of the display unit 14 is switched to the display color indicating the end (ST18), and the registration is completed. The display color can be easily understood by returning from red to green, for example.

According to the present invention, the switch 13 provided on the front door portion 2 is used to input the request for opening / closing the door and the personal identification number, and when the input personal identification numbers match, the reproduction of the disc is stopped and the disc is returned. Since the processing is performed and the reproduction or conveyance processing is continued when they do not match, it is possible to prevent the reproduction or conveyance of the disc from being stopped due to an erroneous operation of the switch that is inadvertently pressed by the user.
Further, when the personal identification numbers match and the front door is opened or closed, the reproduction of the disc is stopped and the process of returning the disc is performed, so that the disc can be reliably exchanged.

In the present invention, since the digit of the personal identification number is represented by the number of times the display section blinks in a predetermined time for inputting the personal identification number, one input section can represent the digit of the personal identification number. Further, the password input in the mode for registering the password and the mode for setting the password is shared by the switch 13, so that the switch can be operated by one switch. Therefore, the number of switches and display units provided on the front door portion can be reduced, and the aesthetic appearance of the front door portion is not impaired.
