Abstract: PROBLEM TO BE SOLVED: To easily take out paper which is jammed in a cutter so as to execute restoration at the time of releasing the paper jamming of the cutter with a manual operation by providing a means for setting the cuter in an open state when a recording paper exchange cover is opened. SOLUTION: At the time of exchanging recording paper, or when recording paper is jammed and a recording part cover is opened, a cover frame 34 is opened and it is opened to the back of the device. When the cover frame 34 is opened, a rod 77 and a link 76 are pulled and the cutter is pulled by the rod 77. An upper blade 61 becomes an open state and it stops. Namely, a cutter part becomes a state where the upper blade is opened and the blades are opened. Since the cutter is opened, the release becomes easy even if the exchange of recording paper, paper insertion and paper jamming occur. Even if the blade of the automatic cutter is in any position owing to paper jamming, it automatically comes to the open position of the cutter and it can be normally operated hereafter.

Title: Eddy current type decelerating device for vehicle
Inventor: HOTSUTA MASAMOTO
IPC: H02K49/02
Filed: 1994-03-14
Abstract: PURPOSE:To reduce a driving loss of engine during the running by supporting a magnetic material disk having a cooling fin at the position opposed to an electromagnet holding a rotor so that the disk can be freely rotated with a shaft and displaced in the axial direction and selectively transmitting rotation of the rotor to the disk to provide an elastic material between the rotor and disk. CONSTITUTION:Since a disk 7 having a cooling fin 2 is connected or separated to or from a rotor 1 depending on excitation by an electro-magnet 3, the heat generated in the rotor 1 during deceleration is cooled by the cooling fin 2. During the normal running, since the disk 7 is caused to rotate at a low speed by the shaft 4, driving loss by blowing with the cooling fin 2 can be reduced. During the acceleration, the driving loss can be reduced depending on the mass of the cooling fin 2.
