ない。(Problems to be Solved by the Present Invention) However, since both methods move the suction means in the feeding direction, the moving mechanism itself is large and complicated, and the film sheet must be lifted up by the suction means before being lifted up. It has the disadvantage that it takes more time than necessary to send it out. In addition, in both methods, the film sheet is attracted by a suction means and is then sandwiched between the transport a-ra pair. I don't have the means.

One of the main features of the present invention is that it has a small and simple structure, can shorten the time required for feeding, and can also be used to clamp a film sheet to a pair of conveying rollers. It is an object of the present invention to provide a film sheet feeding mechanism capable of reliably detecting infiltration with a simple mechanism.

を説明する。(Means for Solving the Problems) In order to achieve the above object, the film sheet feeding mechanism according to the present invention is configured to transport one film sheet lifted from a supply cassette by a suction means to the rotation of a pair of transport rollers. In a feeding mechanism for a film sheet that feeds out a film sheet in one direction, the pair of conveying rollers is attached to a moving lever, and while rotating the pair of conveying rollers, the pair of conveying rollers is moved from the front in the feeding direction to the nipping position of the leading edge of the film sheet at approximately the same height. A substantially semicircular arc-shaped sensor is installed on the moving lever so as to be reciprocally movable, and one end of the sensor bulges toward the supply cassette side from the transport a-ra pair, and the tip is located slightly above the lower transport roller. The present invention is characterized in that it is provided with a sensor lever that is swingable, and that a switch means that is operated by the movement of the sensor lever is provided so that the sensor lever comes into contact with the film sheet (embodiment). DESCRIPTION OF THE PREFERRED EMBODIMENTS The overall structure of a laser beam printer equipped with an embodiment of a cloth handling mechanism according to the invention will be shown, and its outline will first be explained.

とができる。(Effects of the Invention) As is clear from the above description, according to the present invention, the leading edge of the film sheet is sandwiched by moving the pair of conveying rollers without moving the suction means in the feeding direction. , the moving means can be made smaller and simpler than conventional ones, and since the transport roller pair itself rotates and moves in the feeding direction to send out the film sheet, the sheet can be moved further away by the amount of movement. Therefore, the printing speed can be increased. In addition, the moving lever equipped with the pair of conveying rollers has a sensor lever whose tip end has a semi-circular sensor portion and a switch means, so that it is possible to detect whether or not the moving lever has been inserted into the pair of conveying rollers. Since it can be used, it can be used in various operation sequences of the Ifi device to easily obtain many additional functions.

特徴とするフィルムシートの送り出し機構。(1) In a film sheet feeding mechanism that feeds out one film sheet lifted from a supply cassette by a suction means in one direction by rotation of a pair of conveying rollers,
The pair of conveying rollers is attached to a moving lever, and the pair of conveying rollers is rotatably driven and installed so as to be able to reciprocate from the front in the feeding direction to the sandwiching position of the leading edge of the film sheet at approximately the same height, and on the moving lever, A sensor lever is provided to be able to swing freely, and is equipped with a substantially semi-circular sensor portion whose one end bulges out toward the supply cassette side from the pair of transport rollers and whose tip is located slightly above the lower transport roller. A film sheet feeding mechanism characterized in that a switch means is provided which is operated by movement of the sensor lever based on contact.
