Description

  The present invention relates to a rental locker system that is installed in, for example, a station and can use a locker box for a plurality of users.

  Conventionally, what can be used as a locker system using a prepaid card is disclosed in, for example, Japanese Patent Laid-Open No. 7-30554. In this locker system, a prepaid card is inserted into a card reader when the locker is used, and the locker usage fee is withdrawn from the prepaid card so that the locker can be used.

Japanese Patent Application Laid-Open No. 2002-150324 discloses a technique for charging the commuter pass with the change at the time when a commuter pass is issued in a commuter pass issuing machine. In addition, it is described that the change charged in the commuter pass can be converted into cash by a change cashing apparatus. Furthermore, in recent years, there is also a technology that allows a vending machine charge to be charged to a mobile phone and uses the vending machine with the charge amount of the mobile phone.
JP-A-7-30554 JP 2002-150324 A

  However, when the charge amount of a prepaid card, a mobile phone, or the like decreases, a problem arises in terms of convenience during use. For example, in Japanese Patent Laid-Open No. 7-30554, when the balance frequency of the prepaid card is less than the locker usage fee, the prepaid card is merely returned, and in that case, the locker cannot be used. Further, when the balance frequency that cannot be used for the locker remains in the prepaid card as it is, the balance frequency cannot be used effectively unless the prepaid card is charged and compensated.

  Also, in JP-A-2002-150324, in order to eliminate the inconvenience of running out of change in a commuter pass issuing machine, when a commuter pass is purchased with a commuter pass issuing machine, change is charged to the commuter pass. ing. Also, only the change bills are paid out and the fraction is charged to the commuter pass. For this reason, the commuter pass remains charged, and the change charged to the commuter pass cannot be changed into cash unless the automatic ticketing machine is operated. That is, there is a problem in that it is troublesome because it cannot be cashed unless it is operated separately from the regular purchase. This also applies to the case of Japanese Patent Application Laid-Open No. 7-30554 in which cash can be converted into cash equivalent to the balance frequency by a cashing apparatus.

  The present invention makes it possible to use a rental locker with a prepaid card, a mobile phone, etc., and to cope with a shortage of charges, etc., or to make it easier to settle a charge fee for a portable means such as a prepaid card, a mobile phone, etc. The problem is to increase the convenience when using the locker.

  The loan locker system according to claim 1 enables the use of the locker by the cash inserted into the cash slot and enables the use of the locker based on the electronic cash charged to the portable means. When the electronic cash in the portable means is insufficient with respect to the usage fee of the locker, the usage fee is calculated from the sum of the additional cash inserted into the cash slot and the electronic cash in the portable means. It is characterized by collecting and enabling the use of the locker.

  The loan locker system according to claim 2 is the loan locker system according to claim 1, wherein there is a fishing amount by collecting the usage fee with respect to the sum of the additional cash and the electronic cash in the portable means. It is possible to select whether to charge the fishing amount to the portable means or to pay out the entire amount of the fishing amount in cash.

  The loan locker system according to claim 3 enables the use of the locker by the cash inserted into the cash slot and enables the use of the locker based on the electronic cash charged to the portable means. When the electronic cash in the portable means is insufficient with respect to the usage fee for the locker, the usage fee is calculated from the sum of the additional cash inserted into the cash slot and the electronic cash in the portable means. Collecting, paying out the remaining fishing amount in cash, and deleting all the electronic cash charged in the portable means.

  A loan locker system according to a fourth aspect is the loan locker system according to the first, second, or third aspect, wherein the portable means is an IC card and / or a mobile phone.

  According to the loan locker system of claim 1, even when using a locker with a prepaid card or a mobile phone, it is possible to use a payment method in cash for payment of the usage fee. For example, a charge fee for a prepaid card or a mobile phone Even if there is a shortage of money, it is sufficient to pay with cash, so the versatility of the usage method is expanded and the convenience is increased. Further, even if the charge fee is insufficient, a complicated operation at the time of use in which the use operation is stopped and the use operation is performed again after the end of the charge operation can be considerably improved.

  According to the loan locker system of the second aspect, the same effect as the first aspect can be obtained, and change can be charged.

  According to the loan locker system of claim 3, when the electronic cash charged in the portable means is less than the locker usage fee, the electronic cash that cannot be used effectively can be used together with the additional cash, and fishing. Since the amount of money can be obtained in cash, and the remaining charge amount of the portable means becomes zero, the charge can be settled without using a separate settlement operation when using the locker, and the settlement is simplified.

  According to the rental locker system of the fourth aspect, the same effect as that of the first, second or second aspect can be obtained, and when an IC card is used as a portable means, for example, an ID code is transmitted by an automatic ticket gate at a station, etc. A card-type prepaid card (for example, “Suica” (trademark)) used to complete the service can be used, and in particular, a rental locker system is often installed in a station or the like, so that the user can easily use it. In addition, when a mobile phone is used as a portable means, a locker box can be used with a mobile phone that has been widely spread in recent years, which makes it easier for users to use.

Next, in step S35, it is determined whether or not an excess fee has been generated. If not, the locker locking device 21 corresponding to the ID code is unlocked in step S36 and the process returns to the main routine. If an excess charge has occurred, it is determined in step S37 whether or not the charge amount is greater than or equal to the excess charge. If the charge amount is equal to or greater than the excess charge, the charge amount is displayed in step S38 and a display for confirming the payment by charge is performed. If there is no charge payment instruction in step S39, the process directly returns to the main routine. If there is a charge payment instruction in step S39, infrared communication with the mobile phone T is performed in step S40. The charge is deducted from the charge data (the charge data of the mobile phone T is rewritten), the lock device 21 of the locker corresponding to the ID code is unlocked in step S36, and the process returns to the main routine.

  If it is determined in step S37 that the charge amount is not equal to or greater than the excess charge, in step S41, a shortage amount with respect to the excess charge and a display requesting input of a charge are displayed, and a timer is started in step S42. In step S43 and step S44, it is monitored whether a fee is charged. When a predetermined time has passed without charging, the flow returns from step S44 to the main routine. If a fee greater than the shortage amount is input within a predetermined time, it is determined in step S45 whether or not there is change (whether change has occurred). Hereinafter, the processes in steps S45 to S51 are the same as those in steps S19 to S25 in FIG. 4, and a charge process for charging the change to the mobile phone T and a cash process for paying the change in cash are performed. Similarly, when this cash process is performed, the charge amount is zero.

  As described above, the locker can be used with the electronic cash charged in the mobile phone, and the cash can be paid by the personal identification number method or the IC card method. Further, even if the charge amount of the mobile phone is insufficient, it is only necessary to pay in cash by the process as it is, so that when the charge amount is insufficient, it is not necessary to start over from the beginning, and the complicated operation at the time of use can be improved. In addition, when the charge amount is insufficient, the charge amount that cannot be used as it is for the locker can be settled to zero. That is, if the user has a high usage frequency of the rental locker, the user may charge the mobile phone, and the user with a low usage frequency may settle the charge amount to zero.

  In the above embodiment, a charge process for charging the change to the mobile phone T is provided so that the user can select it. However, the change may be always paid out in cash.
