第１項に記載の携帯型印字機。[Claims for Utility Model Registration] 1. A device that is held in hand and moves on a paper surface in the printing direction to rotate a rotating body that comes into contact with the paper surface, and in synchronization with the rotation, transports a film ribbon and records recorded information. In a portable printing machine that sequentially prints on the paper surface using a thermal head while calling the film ribbon, when moving in a direction opposite to the printing direction, reverse rotation transmission from the rotating body is cut off. A one-way clutch mechanism is provided to prevent reverse feeding of the film ribbon, and
A switch operating member that rotates integrally with the rotating body or a member to which the rotation of the rotating body is transmitted is provided, and the switch operating member is operated to stop supplying current to the thermal head when the thermal head moves in the opposite direction. A current supply switch is arranged to
Portable printing machine. 2. A check mechanism that prevents a member to which the rotation of the rotating body is transmitted from reversing when the one-way clutch mechanism is moved in the opposite direction, and a member that is blocked when the reverse rotation is prevented by the check mechanism. and a slip mechanism that generates a slip between the rotating body and the rotating body. 3. The switch operating member is made of a spring member,
It is attached to the rotating body or a member to which the rotation of the rotating body is transmitted by its own elasticity so as to rotate sufficiently together with the rotating body, and when a rotational load of a certain level or more is applied to the switch operating member, the switch operating member and the A structure that causes slip between the rotating body or a member to which the rotation of the rotating body is transmitted;
The portable printing machine according to claim 1 of the utility model registration claim. 4. The portable printing machine according to claim 1, wherein the current supply switch is a microswitch that is fixedly disposed within the device, facing the switch actuating member.
