<p>PURPOSE:To provide the titled appraratus able to satisfy various kinds of users' specifications and easy to find out a defective part by independently constructing, in circuit, a heating section and driving section by a group respectively and arranging only a circuit plate section in conformity with the users' specifications. CONSTITUTION:A heating section 1 and a driving section 2 are respectively composed of independent circuits which are grouped by a certain number of heating element 111 as a unit. An interconnecting wiring between the heating section 1 and driving section 2 is provided by a wiring of a circuit plate section 3 where also supplies them with signals and power from external sections. A content of a shift register 212 is transferred to a memory circuit 213 in accordance with a strobe signal from an electronic circuit 211, a driving circuit 211 is driven, and the required heating elements 111 generate heat crrespondingly according to a recording signal through lead wires 112. A device to be designed in conformity with a user's specifications is provided only for the circuit plate section 3. A check is conducted by each group which is divided into a small section, and it is easy to detect a failed part.</p> |
