In other words, it is checked here whether the system is in the power-on state from the start step (step 101). If it is in the power-on state, it is checked whether the unit A to the deck unit 21 is in the connected state (step 102). 12a) is kept lit (step 103); if connected, it is checked if unit B to deck unit 22 is connected (step 104). Then, it is checked whether the unit C to the deck unit 23 is in the connected state (step 105), and if not connected, the segment indicator 12a is kept in the state where the lower segment d is lit (step 106).

If the connection is made in step 105, it is checked whether the units A and B are connected (step 107). When not connected, the segments a and g are kept lit (step 108). Check whether all are connected (step 109), and if not connected, keep the segment indicator 12a in the middle, lower and lower segments g and d lit (step 110), and then again connect units A and C. If there is no connection (step 111), only the upper and lower segments a and d remain lit when not connected (step 112).

In step 111, if the units A, C are poor, it is checked whether the units A, B, C are connected (step 113), and if they are not all connected, the segment indicator 12a is connected to the upper segments a, g, d. Is maintained in a lit state (step 114), and if connected, a series of processing steps are returned to step 101.

According to the present invention of the above configuration, the deck units 21 to 23 are inserted into the deck units 21 to 23 on the main body 24 side of the copying apparatus 2 as shown in FIGS. 1 to 4, respectively.

If it is not connected by checking whether it is not connected, only the segment g remains lit. If it is not connected, check whether the unit C for the deck unit 23 is connected. If not, turn the segment indicator 12a to turn on the segment d. It keeps in the state (step 101-106).

If the unit C is connected in the above step, it is checked whether the units A and B are connected, and when they are not connected, the segments a and g are kept lit, and the units B and C are all connected again. If it is not connected, if not connected, keep the segment indicator 12a in the state where the middle and lower segments g and d are lit, and check whether the units A and C are connected again. Only a and d remain in the lit state (steps 107 to 112).

In the above step, if units A and C are poor in connection, it is checked whether units A, B and C are connected, and if they are not all connected, the segment indicator 12a turns on the upper segments a, g and d. (Step 103, 114).
