Abstract

PURPOSE: To prevent collision between a paper feed base and a machine body, etc., by performing the up and down motion of the paper feed base and the ingress and egress motion of a paper feed frame by means of a single drive source.
CONSTITUTION: This device is provided with a paper feed frame 20, which internally mounts a paper feed base 2 in an up and down movement-possible shape and is installed to a machine body in an ingress and egress-possible form, a drive source 24 for carrying out the ingress and egress motion of the paper feed frame 20 to the machine body 22 and the up and down motion of the paper feed base 2 in the paper feed frame, a 1st locking device 27, which allows the up and down motion of the paper feed base 2 only when the paper feed frame 20 is positioned at paper feed locations in the machine body 22 and locks the paper feed base at the lowest side location when the paper feed frame is positioned at other locations, and a 2nd locking device 28 for preventing the movement of the paper feed frame when the paper feed base parts from the lowest side location. Above-mentioned arrangement can prevent unexpected situations, such as, collision between the paper feed base and the machine body, etc. by the rise of the paper feed base in the case when the base is positioned at locations except the paper feed locations of the paper feed frame or the ingress and egress motion of the paper feed frame as the paper feed base remains as it rises.
