PRINTER

To enhance mounting strength of a connector mounted on a substrate.SOLUTION: A printer includes: a substrate unit having a substrate to which a connector to which an external device is connected is attached to an edge portion and a holder attached to a mounting surface to which the connector of the substrate is attached; and a printer housing to which the substrate unit is attached. The printer housing has a first contact portion and a second contact portion that are in contact with the substrate unit. The first contact portion is in contact with at least a part of a region corresponding to a region of the substrate to which the connector is attached, on one surface of the substrate unit. The second contact portion is in contact with at least a part of a region corresponding to the region of the substrate to which the connector is attached, on the other surface of the substrate unit.SELECTED DRAWING: Figure 7 【課題】基板に実装されたコネクタの取り付け強度を高める。【解決手段】プリンタは、外部機器が接続されるコネクタが縁部に取り付けられた基板と、基板のコネクタが取り付けられた実装面に取り付けられたホルダと、を有する基板ユニットと、基板ユニットが取り付けられるプリンタ筐体と、を備え、プリンタ筐体は、基板ユニットに当接する第一当接部及び第二当接部と、を有し、第一当接部は、基板ユニットの一方の面において、基板のコネクタが取り付けられた領域に対応する領域の少なくとも一部に当接し、第二当接部は、基板ユニットの他方の面において、基板のコネクタが取り付けられた領域に対応する領域の少なくとも一部に当接する。【選択図】図７
