PURPOSE: A management system for an accompaniment unit is provided to transfer messages between a CPU(Central Processing Unit) and an accompaniment unit without using an additional unit or line therebetween. CONSTITUTION: A management system for an accompaniment unit consists of one and more accompaniment units(31,32,33), a CPU(40) and a background image and caption transmitter(45) for transmitting background images and caption to the accompaniment units. The one and more accompaniment units are connected with the CPU via a data transmission/reception unit. The data transmission/reception unit is used with a common line. The accompaniment units are divided and connected to the common line. Therefore, the accompaniment units are additionally connected to the common line without increasing the number of lines. The CPU displays if a message to the CPU is transmitted from one of the accompaniment units completely. Thereby, a manger recognizes the accompaniment unit receiving the message easily.
