<p>An installation guide mechanism is provided which allows a paper roll to be easily set onto a roll shaft of a paper magazine. A roll guide is connected with a roll shaft by inserting an insertion hole open at the rear end surface of a roll guide onto a holder ring at the front end of the roll shaft in a paper magazine. A tapered portion is arranged at the front end of the roll guide. After aligning a paper roll with the roll guide so that the tapered portion is inserted into the center hole of the paper roll, the paper roll is guided by the roll guide and is moved onto the roll shaft. A magazine guide also can be installed on a floor located under a magazine engaging port arranged on a bottom of an outer surface of a photographic printing machine. A side guide and a center guide are configured on the magazine guide. A pair of side rollers, two pairs of ground contact rollers and a pair of protruded members are included. As the paper magazine is pushed onto the magazine guide, the side roller is guided by the side guide and the protruded members are guided by the side guide surfaces of the center guide to adjust the direction of the paper magazine. The front roller and the rear roller installed on the bottom surface of the paper magazine are rolled along the center guide to reduce the moving resistance. <IMAGE></p> |
