PROBLEM TO BE SOLVED: To provide a charger set wherein a user can be encouraged to avoid frequently using only a specific charging slot. SOLUTION: The charger set 1 includes multiple charging slots 2, and each slot 2 is provided with a charge display section 4 and a number-of-setting times display section 3. When a rechargeable battery pack is set in a charging slot 2, the locking portion of the rechargeable battery pack is engaged with a locking mechanism section 6 and the rechargeable battery pack is charged through a connector 5. Each locking mechanism section 6 forms a part of a sensor, and is constructed as a switch that closes an electric circuit each time a locking portion is engaged. This sensor is connected to a counter, and each counter is connected to the corresponding number-of-setting times display section 3. Each counter counts the number of times when a locking portion is engaged with the corresponding locking mechanism section 6 to turn on an electric circuit. That is, each counter counts the number of times when the corresponding sensor detects setting of a rechargeable battery pack. This number of times is displayed in the corresponding number-of-setting times display section 3. COPYRIGHT: (C)2007,JPO&INPIT
