Thus, because the printing unit can be drawn out from the main body of the apparatus, maintenance work to the printing unit can be easily performed in a state that the printing unit has been drawn out from the apparatus.
41. An image forming apparatus according to claim 40, wherein the maintenance mechanism is drawn from the front of the image forming apparatus. Description
CROSS-REFERENCE TO RELATED APPLICATIONS The present application claims priority and contains subject matter related to Japanese Patent Applications No. 2003-328769 and No. 2004-261326 filed in the Japanese Patent Office on Sep. 19, 2003 and Sep. 8, 2004, respectively, and the entire contents of each of which are hereby incorporated herein by reference.
As illustrated in FIG. 12 illustrating a state of the connector part 180, at the side of the first connector board 180 a arranged are a connector 181 a for connection with the main body control board 190, connectors 181 b, 181 c and 181 d connecting with respective parts of the printing unit 110, such as the printing heads mounted to the carriage 121 of the printing mechanism part 120, the maintenance mechanism part 150, and the blank printing mechanism part 160, and a connector 181 e for connection with the second connector board 180 b. Wiring patterns are formed at the back surface of the first connector board 180 a to connect the connector 181 a with the connector 181 b, the connector 181 c, the connector 181 d and the connector 181 e. By connecting a connector 191 at a tip end of signal lines 400 from the main body control board 190 with the connector 181 a, connection of the main body control board 190 and respective parts of the printing unit 110 is realized through the intermediary of the wiring patterns and the connectors 181 b, 181 c and 181 d and connecting cables 187 b, 187 c and 187 d connecting to the respective parts of the printing unit 110. The connector 181 a, the connector 181 b, the connector 181 c, the connector 181 d and the connector 181 e are arranged such that respective connecting cables do not cross each other and thereby noise will not be picked up. The second connector board 180 b is connected with the first connector board 1980 a via the connector 181 e and is configured such that signals for controlling the sub-scanning conveying mechanism part 140 and the printing mechanism part 120 are inputted and outputted via a connector 181 f. In FIG. 12, the connector part 180, i.e., the first connector board 180 a and the second connector board 180 b, are arranged substantially along the entire portion of the side surface of the printing unit 110 in the longitudinal direction, however, the first connector board 180 a and the second connector board 180 b are actually arranged at positions closer to the rear side plate 114 of the printing unit 110 as illustrated in FIG. 8 such that lengths of the connecting cables 187 b, 187 c, 187 d and 187 e are minimal and thereby pick-up noise is minimized. Further, the connector 181 a is arranged in the first connector board 180 a at a position closest to the rear side plate 114. Here, the main body control board 190 is arranged at a rear part in the main body of the copying apparatus 1 and at the side of the first conveying path cover 1 b, so that lengths of the connecting cables 400 of the connector 191 of the main body control board 190 are made relatively short. Further, as described above, the connector part 180 configured by the first connector board 180 a and the second connector board 180 b is provided to the side surface of the printing unit 110 opposing the second conveying path cover 1 b when the printing unit 110 is accommodated in the main body of the copying apparatus 1, so that the connector part 180 is exposed by opening the second conveying path cover 1 b. Thus, by opening the second conveying path cover 1 b and by detaching the connector 191 of the main body control board 190 from the connector 181 a of the first connector board 180 a, electrical connection between the printing unit 110 and the main body control board 190 is disconnected, and thereby the printing unit 110 can be detached from the main body of the copying apparatus 1. Further, because the lengths of the connecting cables 400 extending from the main control board 190 of the main body are made relatively short as described above, when detaching the printing unit 110 from the main body of the copying apparatus 1, the connecting cables 400 will not be obstructive.
