Patent number: 9987846Abstract: 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.Type: GrantFiled: June 3, 2015Date of Patent: June 5, 2018Assignee: Seiko Epson CorporationInventors: Takayuki Shiota, Hiroyuki Tajima, Akira Anami, Kazuhiko Tsuyama, Naoki Sakamoto
