BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-charger for charging a power supply of a terminal device used for inventory of a store or the like.

[0002]

2. Description of the Related Art Generally, each store or the like is provided with a store controller for storing the number of stocks obtained by subtracting the number of sales on the day from the number of stocks and the number of stocks of the goods together with the amount of each stocked product. When the store controller is accessed, the current stock amount of the product in the store can be known. Conventionally, at the time of stocktaking at such a store, the store controller is accessed and master data is taken into each terminal device, and after the same master data is taken into each terminal device, each stocktaking person uses each terminal device. In each case, they carry out the inventory work of the products they share. Then, the actual number of products is compared with the master data, the input data is corrected, and the like. When such inventory work is completed, each terminal device is reconnected to the store controller, and the above-mentioned terminal devices stored in this device are stored. The inventory data and the slip total data, which are the data of the inventory results, are transmitted to the store controller. In this case, a battery is used as a power supply for each terminal device. After the inventory is completed, the battery is removed from each terminal device, and the removed batteries are individually charged to prepare for the next inventory. .

[0003]

As described above, in the related art, since the batteries which are the power supplies of the terminal devices are individually charged,
The charging operation becomes complicated, and there is a time loss from the completion of charging to the start of charging of the next battery, which takes a long time for charging. As a result, there is a problem that the efficiency of the inventory operation is reduced.

[0004]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the multi-charger of the present invention. In the figure, 1 is a CPU, 2 is a microswitch group for detecting a battery mounted to be charged, 3 is an LED group for indicating that the battery is being charged, 4 is a power supply circuit, 5 is a charging circuit, 6 is a charging circuit. A refresh circuit for lowering a battery to a predetermined voltage before charging for the purpose of using the battery for a long period of time, 7 is a switching circuit, 8 is a voltage / current detection circuit for detecting a refresh voltage of the battery, a charging voltage and a charging current, and T1 to T1. T4 is a charging terminal to which a battery to be charged is attached.

FIG. 2 is an overall perspective view of the multi-charger. In other words, this multi-charger can accommodate up to four batteries (equivalent to four devices) removed from terminal devices used for stocktaking and the like. , The corresponding LED in each LED group 3 is turned on, and after the refresh processing is performed, charging is started. In the case of the present multi-charger, when a plurality of batteries are installed at the same time, the plurality of batteries cannot be charged or refreshed at the same time, but can be sequentially performed. Also, charging and refreshing can be performed simultaneously.

Next, the operation of the CPU 1 of the multi-charger configured as described above will be described with reference to the flowcharts of FIGS. The charging terminals T1 to T of this multi-charger
When a battery is attached to any of the vacant terminals 4, “battery attachment” in step 30 is determined to be “Y” via a detection output of any of the microswitch groups 2, and in this case, step 31 Then, the mounting position and the mounting order of the batteries are checked and stored. In step 32, the abnormality of the attached battery is detected by the voltage / current detection circuit 8
If the determination is "Y", the red LED corresponding to the mounting position in the LED group 3 is blinked, and the process returns to step S30.

If no abnormality is detected in the mounted battery, it is determined in step 34 whether or not the mounted battery can be refreshed through detection by the voltage / current detection circuit 8. Then, it is determined in step 35 whether or not another battery already mounted is being refreshed. If there is no other battery being refreshed and it is determined to be "N", the switching circuit is determined in step 36. 7, the refresh circuit 6 is connected to the corresponding charging terminal to perform a refresh process of discharging the battery and dropping it to a predetermined voltage. Return to If it is determined that the mounted battery cannot be refreshed, it is determined that the battery can be charged immediately.
At step 9, the corresponding red and green LEDs are alternately turned on, and the process returns to step 30. Further, when it is determined that the mounted battery is refreshable and another battery is determined to be refreshing, the corresponding red LED is turned off because of the refresh standby state, and the process returns to step S30.

If the installation of the battery is not detected, it is determined in step 40 that there is a battery being refreshed, and if this is "Y", the completion of refresh of the battery is determined in step 41. The end of the refresh of the battery is determined as “Y” via the detection output of the voltage / current detection circuit 8.
Is determined, the corresponding charging terminal is connected to the refresh circuit 6
And in step 42, the corresponding red and green LEDs are alternately lit to prepare for charging,
Move to the next step 43. Also, if there is no battery being refreshed and it is determined "N" in step 40, the process proceeds to step 43, where it is determined whether there is another battery to be refreshed. If there are batteries to be refreshed, the refresh priority of these batteries is checked in step 44, and the batteries that have been mounted first are refreshed with priority. Thus, the battery installed first is refreshed in step 45, and the refreshed battery and the corresponding red L
The ED is lit (Step 46), and the process returns to Step 30.

Also, when the refresh of the battery being refreshed is not completed ("N" in step 41) and when there is no other battery to be refreshed (step 43)
, “N”) proceeds to step 50 in FIG. In this step 50, it is determined that there is a battery being charged. If this is determined to be "N", it is determined in step 53 that there is a battery to be charged. If there are batteries to be charged, the charging priority of these batteries is checked in step 54, and the batteries that have been refreshed earlier are charged with priority. The battery refreshed first in this way is charged in step 55, and the red LED corresponding to the charged battery is lit (step 56).
Then, the process returns to step 30 in FIG.

In the case of charging the battery, first, the switching circuit 7 is selectively switched to connect the charging circuit 5 to the corresponding charging terminal, and the charging circuit 5 is charged until the battery reaches a predetermined charging voltage.
When the battery voltage reaches a predetermined value based on the detection output of the voltage / current detection circuit 8, the switching circuit 7 is switched and the corresponding charging terminal is disconnected from the charging circuit 5. It is. Therefore, if there is a battery being charged and it is determined as “Y” in step 50, and if the end of charging of this battery is determined as “Y” in step 51 based on the detection output of the voltage / current detection circuit 8, At the end of charging, the corresponding charging terminal is disconnected from the charging circuit 5, and at step 52, the corresponding green LED indicating the end of charging is flashed to determine whether there is a battery to be charged other than at step 53. When the charging of the battery is not completed ("N" in step 51) and when there is no other battery to be recharged ("N" in step 53), the process returns to step 30 in FIG. Determine the presence or absence of batteries to be installed.

As described above, even when a plurality of batteries are mounted, the mounting order is checked, and the refreshing process and the charging process are sequentially and sequentially executed in accordance with the order. In addition, the refresh process and the charging process can be performed separately and simultaneously. That is, for example, while a certain battery is being charged, another battery can be refreshed, and furthermore, what kind of processing is currently being performed on each battery can be identified by displaying the LED.
