O Utility Model Registration Claim 1 A paper loading platform 2 supported on a paper storage frame 1 so as to be freely raised and lowered is raised by a drive means 3 such as a motor or a movement spring, and the paper 4 on this paper loading platform 2 is fed. In a paper feeding device that feeds one sheet by a paper roller 5, a ratchet wheel 6 that is linked to the up-and-down movement of the paper platform 2 and a locking pawl 7 that engages with the ratchet wheel 6 prevents the paper platform 2 from descending. In response to operation 8, the drive means 3 is instantaneously activated in the upward direction of the paper table 2, and the locking pawl 7 is turned into a ratchet wheel! A paper feeding device characterized by being released from /6. 2 Utility model registration claim 1, in which the ratchet wheel 6 is connected to the up and down movement of the paper mounting table 2 via a one-way clutch 9 that allows rotation of the paper mounting table 2 in the upward direction.

Claims

[Claims for Utility Model Registration] 1. A paper loading platform 2 supported on a paper storage frame 1 so as to be able to rise and fall is raised by a drive means 3 such as a motor or an urging spring, and the paper 4 on this paper loading platform 2 is raised as appropriate. In a paper feeding device that feeds one sheet by a paper feed roller 5, a ratchet wheel 6 that is linked to the up and down movement of the paper stack 2 and a locking pawl 7 that engages with the ratchet wheel 6 prevents the paper stack 2 from lowering. , - In response to the paper loading operation 8 such as the empty sensor of the paper 2 and the opening/closing operation of one paper storage frame, the driving means 3 is instantaneously activated in the upward direction of the paper stacking table 2, and the above-mentioned engagement is activated. Stopper 7
A paper feeding device characterized in that the ratchet wheel 6 is released from the ratchet wheel 6. 2 Utility model registration claim 1, in which the ratchet wheel 6 is connected to the up and down movement of the paper mounting table 2 via a one-way clutch 9 that allows rotation of the paper mounting table 2 in the upward direction.
Paper feeding device as described in section.
