PURPOSE:To eliminate the need to prepare a 100yen coin by totalizing and recording the number of played songs by using the KARAOKE playing device as it is without remodeling the device itself. CONSTITUTION:This KARAOKE playing device 1 consists of a KARAOKE counter 10 connected to the device, a reset checker 30 installed at a reception counter, and a checker 20 which is freely attached to and detached from both the KARAOKE counter and reset checker. When a user of the KARAOKE box receives the checker 20 and mounts it on the KARAOKE counter 10, the KARAOKE playing device 1 becomes ready to play and once the user starts a musical performance, the number of played songs is integrated by the checker 20 and stored; and this checker is detached and mounted on the reset checker 30 at the reception counter, so that the number of played songs is displayed on the reset checker for payment. |
