PURPOSE:To reduce the space for handling of lead wires thereby to reduce the size of the body of an apparatus by attaching a head drive circuit and a thermal head to a head holder. CONSTITUTION:A number of common lead wires K, L, M and N and an image signal lead wire Z are arranged between a head drive circuit 4 and a thermal head 2. Since the head drive circuit 4 and the thermal head 2 are attached to a head holder 3, they can be easily hendled with the use of a thermal head unit 1. As a result, the lead wires arranged through the body of an apparatus can be composed only of the drive lead wires i of the head drive circuit 4 and the lead wires j for transmitting image signals from a control circuit 18 to the head drive circuit 4. Thus, it becomes unnecessary to elaborately arrange the numerous lead wires so that the size of the apparatus body can be reduced. |
