Claim Text:
1. A substrate conveying system for an electronic component mounting device, comprising: a mounting device conveyor configured to convey a printed substrate from one end portion to the other end portion of the electronic component mounting device in a first direction that is horizontal; an upstream-side conveyor configured to unload the printed substrate from an upstream-side apparatus positioned upstream of the electronic component mounting device in a conveying direction of the printed substrate; a downstream-side conveyor configured to load the printed substrate onto a downstream-side apparatus positioned downstream of the electronic component mounting device in the conveying direction of the printed substrate; a buffer conveyor arranged between at least one of the upstream-side conveyor and the downstream-side conveyor and the mounting device conveyor; and a controller configured to control operations of the mounting device conveyor and the buffer conveyor, wherein the mounting device conveyor has a function of moving the printed substrate in a second direction that is horizontal and perpendicular to the conveying direction, the upstream-side conveyor is spaced apart from the downstream-side conveyor in the second direction, the buffer conveyor has a function of conveying the printed substrate in the first direction, and a function of moving the printed substrate in the second direction, the printed substrate is transferred from one of the mounting device conveyor and the buffer conveyor to the other in a state in which the mounting device conveyor and the buffer conveyor are positioned in the same position in the second direction, the buffer conveyor includes a downstream-side buffer conveyor installed between the downstream-side conveyor and the mounting device conveyor, and the controller is configured to:
