here is your problem:
signal array_index: std_logic_vector (1 to 0);
it is a null array, as 1 is higher than 0. I think you meant (1 downto 0)

tricky, thanks for your help - you are absolutely right.
1) I changed:
signal array_index: std_logic_vector (1 to 0);
To:
signal array_index: std_logic_vector (1 downto 0);
2) Similar mistake - I changed:
type array_type is array (3 to 0) of std_logic_vector (9 downto 0);
To:
type array_type is array (3 downto 0) of std_logic_vector (9 downto 0);
And my program was compiled in Quartus II.

Another point - why is array index a std_logic_vector? save your fingers from RSI, and make it:
signal array_index : integer range 0 to 3;

Thank you for your advice - i will be use integer type for array index in future projects.

Problem was solved :-P
