Abstract

PURPOSE:To easily and clearly confirm the remainder of a recording form by storing the recording form on a recording form reception base and observing the recording form and the colored display part of a display plate through an inspection hole. CONSTITUTION:When the winding diameter of the recording form 2 decreases as the recording form 2 is used, the colored display part of the display sheet 10 is seen through the inspection hole 9. A user decides that the remainder of the form 2 is small, checks the stock of a form 2, and takes the steps for ordering when the form is out of stock. Then when the form 2 is further used and the colored display part of the sheet 10 is seen through the window 9, it is judged that the remainder of the form 2 is nearly zero and the form 2 is replaced with a new form 2. At this time, the form 2 is drawn toward a holding wall 32 by the conveyance of a feed roller 6 and the bottom plate 31 of the recording form reception base 3 has a downward slope toward the sending-out side of the form 2, so the form 2 is held at a specific position while pressed against the holding wall 32. Therefore, the remainder of the form 2 is not misjudged.
