A method for connecting circuit boards, comprising: (i) preparing a first circuit board having connection parts assigned to end parts of a plurality of conductor wirings, and a second circuit board having connection parts assigned to corresponding end parts of a plurality of conductor wirings; (ii) disposing the connection parts of the first circuit board to face the connection parts of the second circuit board with a thermosetting adhesive film between the connection parts of the circuit boards; and (iii) applying heat and pressure to the connection parts and to the thermosetting adhesive film sufficiently high to thoroughly push away the adhesive film so as to establish electrical contact between connection parts of the circuit boards facing each other and to allow for curing of the adhesive; wherein the conductor wirings constituting the connection parts of at least one of the first and second circuit boards contain non-linear wirings.

Method for mutually connecting circuit boards

An image recording apparatus consists of a control system including a CPU, an image input terminal, an image processing system, an image output terminal, and a user interface. An I/O controller is provided in each of the above units. During the power-on sequence of the apparatus, the CPU executes an interrupt test for checking whether interrupt processes of the CPU with respect to sync signals are performed correctly, and an I/O port operation test for confirming that an I/O port of each I/O controller functions correctly. When a prescribed button is pressed at the user interface, the CPU enters a diagnostic copy job mode, in which copies are actually produced in the same manner as in a normal copy mode to identify a unit in trouble.
