Zusammenfassung:To provide an image formation device which can amplify a signal transmitted through a cable according to change of attenuation characteristics of the cable.SOLUTION: An image formation device includes: a transceiver circuit 13 which transmits a signal; a carriage which is mounted with a recording head 21 and moves relative to the transceiver circuit 13; a counter 26 which counts the number of movements of the carriage; an amplifier circuit 22 which is mounted on the carriage and amplifies the signal received from the transceiver circuit 13 through a cable 30; and a carriage control part 27 which changes an amplification factor of the amplifier circuit 22 based on a count value of the counter 26.SELECTED DRAWING: Figure 2 【課題】ケーブルを介して伝送された信号を、ケーブルの減衰特性の変化に応じて、増幅させることができる画像形成装置を提供する。【解決手段】信号を送信するトランシーバー回路13と、記録ヘッド21が搭載され、トランシーバー回路13に対して移動するキャリッジと、キャリッジの移動回数をカウントするカウンター26と、キャリッジに搭載され、ケーブル30を介してトランシーバー回路13から受信した信号を増幅する増幅回路22と、カウンター26のカウント値に基づき、増幅回路22の増幅率を変更するキャリッジ制御部27とを備えた。【選択図】図2
