A weighing scale has a housing accommodating a load cell, having fixed, deformation, movable portions. The fixed portion is connected to the housing, and the movable portion bears a spider having a platter. The deformation portion has a strain gauge measuring a weight acting on the platter. A strip light is attached to an external wall of the housing. A state machine of a controller depicts states of the weighing scale. The controller either: applies a voltage to the strip light in a pulsed manner when the state machine is in a first state, and applies a voltage to the strip light constantly in a second state; or applies a voltage to a third group of LED lamps of the strip light constantly in the first state, and applies a voltage to a second group of LED lamps of the strip light constantly in the second state.

A sheet conveying device includes a plurality of switching portions each having a plurality of branch paths branching off from a standard conveying path and a plurality of sheet collection portions configured to collect sheets at a later stage of the branch paths. The switching portions can selectively execute a normal conveying process in which each of a plurality of sheets is conveyed along the standard conveying path, and an emergency conveying process in which each of the plurality of sheets is conveyed to each of the sheet collection portions. The control device, when a jam is detected, causes a terminal switching portion, which is located farthest downstream in the sheet conveying direction among upstream switching portions having a path branching from an area downstream of the jam area, to execute the emergency conveying process, and causes the other portions to execute the normal or emergency conveying process.
