  • Patent number: 11659673
    Abstract: An image reading apparatus includes a lower unit, an upper unit, a flexible flat cable (FFC), a GND harness, an accommodating portion, and a widened portion. The lower unit includes a main board. The upper unit includes a sub-board and is pivotably connected to the lower unit. The FFC and the GND harness have flexibility and couple the main board and the sub-board to each other. The accommodating portion accommodates the FFC and the GND harness. A length of the GND harness in a width direction is larger than a length corresponding to a gap between the accommodating portion and the FFC.

  • Patent number: 9987846
    Abstract: A printer includes a cap unit, a transporting driving roller, a power transmitting unit, and a pump. At least a part of each of the cap unit, the transporting driving roller, the power transmitting unit, and the pump has the same height in a height direction of the apparatus (a Z-axis direction) and the cap unit, the transporting driving roller, the power transmitting unit, and the pump are arranged along a direction (a Y-axis direction) intersecting with a rotational axis line direction (an X-axis direction) of the transporting driving roller. Therefore, it is possible to arrange so as to suppress each dimension of the cap unit, the transporting driving roller, the power transmitting unit, and the pump in a height direction and it is possible to contribute to the miniaturization of the apparatus.
