A disclosed device printer apparatus includes a recording sheet conveying block holding a recording sheet and including a light emitting element, and a first light receiving element; a head block printing characters, graphics or the like on the recording sheet including a second light receiving element positioned to face the light emitting element so as to directly receive the light; and a control circuit connected to the light emitting element, the first light receiving element, and the second light receiving element, wherein the control circuit determines, when the light is detected by the second light receiving element, that the recording sheet does not exist between the light emitting element and the second light receiving element, and when the light is not detected by the second light receiving element and is detected by the first light receiving element, that the recording sheet exists.
