A theft-prevention ink pack device is provided, comprising a support member ( 70 ) having support lugs ( 73 a, 74 a, 75 a, 75 b) within a case ( 130 ) having ink spouts ( 66 ) and knife edges ( 69 ), a tray member ( 80 ) supported by the lugs ( 73 a, etc.), spaced from the knife edges ( 69 ), an ink pack ( 90 ) placed on the tray member ( 80 ) and having a bag ( 92 ) containing ink ( 91 ), a pressboard ( 100 ) positioned behind the ink pack ( 90 ), and conical compression coil springs ( 120, 121 ) for pushing the pressboard ( 100 ). When the support member ( 70 ) is moved as it is pulled, the support provided by the support lugs ( 73 a, etc.) of the tray member ( 80 ) is cancelled to cause the tray member ( 80 ) to fall down and the ink pack ( 90 ) is broken by the knife edges ( 69 ) and urged under pressure by the spring forces of the springs ( 120, 121 ) via the pressboard ( 100 ) to cause the ink to spurt through the ink spouts ( 66 ).
