is lifted, so the shelf 13 moves clockwise around the support shaft 35 Fj! 1ml is added. In this case, the support shaft 35
Due to the zero rotation, the detection plate 37 moves by 1 g, and the groove portion 38 of the detection plate 37 is connected to the light emitting element 41. It is removed from the optical path of the light receiving element 42, and then the above optical path is formed by the hidden #11 portion 39. As a result, a pulse signal is output from the output circuit 57 and given to the control circuit 58, so the control signal from the control circuit 58 is cut off and the relay 59 is restored.
The contact 60 is opened and the drive of the motor 63 is stopped.
In addition, in this embodiment, the time from when the motor 63 makes one revolution until it stops is 0. It is about g seconds. Therefore, the motor 63
The position of the shelf section 130 when the paper has stopped is as shown in the list 8E, and the paper P that has entered the feeding section 14 advances in the direction of the arrow W and is delivered from the inlet port 8 of the kerato section 11.

When the storage of the third sheet of paper is completed, a pulse signal is output from the pair 5 to the T-coupling setting circuit 6s. In this case, when the control MM 64 is given a pulse signal from the position detection circuit 57 and the pulse signal is given from the collation setting circuit 65, it outputs an III control signal to the relay 66, and its contact number 7 close. Therefore, the motor 63 is driven, rotates the 11M section 13 counterclockwise, and rotates the 8 section 13 as shown in FIG. 3 or 7.
Return to the initial position shown in the figure. When the S part 13 is returned to this position, the optical path of the light emitting element 54 and the light receiving element 515 is formed by the groove part 38 of the detection plate 37, so a pulse signal is output from the position detection circuit 67, and the control! The control signal from the 1 circuit 58 is rejected, and the contact 60 of the relay 5- is opened.
