Abstract: Production past record information showing the execution time point of each step is accumulated for each product loaded in a production system. A supporting system calculates, for each step, a retention increase rate at each time point on the basis of the production past record information. The “retention increase rate” is an amount of increase in retention number per unit time. The supporting system displays a holistic chart for a production situation, which has a time axis and a step axis (axis perpendicular to the time axis and corresponding to steps). A display mode of each position in the holistic chart depends on whether a retention increase rate for the time point and step corresponding to the position is a negative value, zero, or a positive value, and a difference between the retention increase rate and a rate reference value (a reference value for the retention increase rate).

Abstract: A manual feed tray includes a tray body and a lift unit, and the lift unit includes a lift plate, a lift spring and a pair of cursors. The cursor includes a guide portion. When the manual feed tray is closed from a sheet feeding state of the lift plate, the guide portion comes into contact with a facing wall portion, whereby a downstream side of the lift plate in a covering direction moves downward. Thus, even if the manual feed tray is closed with the lift plate moved upward, the lift plate smoothly moves downward.
