項(1)の給紙装置。[Scope of Claim for Utility Model Registration] (1) It is equipped with an upper and lower paper feed roller and an upper and lower guide member that is placed after the paper feed roller and guides the recording paper to these rollers, and the shaft of the upper paper feed roller is The upper guide member is supported in a vertically movable manner and is biased by an elastic force in a direction in which the upper paper feed roller is pressed against the lower paper feed roller, and at least a portion of the upper guide member can rotate around its front end to open and close. In the paper feed device of the recording device, which serves as an opening/closing unit, there are two types of pressure on the shaft of the upper paper feed roller: a pressure-bonded state in which the upper paper feed roller presses against the lower paper feed roller, and a non-pressure state in which it separates upward from the lower paper feed roller. A switching member is attached to the switching member, and this switching member is integrally provided with a switching lever that projects above the opening/closing part of the upper guide member in a crimped state, and when the opening/closing part of the upper guide member is opened, the switching member is attached. A paper feeding device characterized in that when a lever is pushed, the switching member is switched to a non-pressing state. (2) The recording device consists of a fixed lower unit and an upper unit that is attached to the lower unit so as to be movable up and down and can be opened and closed.The paper feeding device is installed in the lower unit, and the upper unit is When the upper unit rotates downward and closes from the state where it is opened and the switching member is switched to the non-crimped state, the switching lever is pushed by a part of the upper unit, and the switching member is switched to the crimped state. 2. The paper feeding device according to claim 1, wherein
