２の側壁によつて防止される。 First, the cutter 2 is inserted through the mounting opening 8 of the mounting member 1, and the two are placed in a positional relationship as shown in FIG. The locking piece 5 of the cutter 2 is locked with the locking protrusion 6 of the member 1, and the elastic pieces 3 of the cutter 2 are elastically engaged with the recess 4 of the member 1. It is engaged with the notch 10 provided in the. Therefore, the locking piece 5 and the locking protrusion 6 prevent the cutter 2 from coming off in the vertical direction at the locking piece 5, and preventing the cutter 2 from coming off from the member 1 in the left-right direction and upward direction. The elastic piece 3 and the recess 4 prevent the cutter 2 from coming off downward from the member 1 at the elastic piece 3, and the engaging part 11 and the notch 10 prevent the cutter 2 from coming off downward from the member 1. The cutter 2 is prevented from coming off in this direction by the side wall of the cutter 2.

い。 On the other hand, when removing the engaging part 11, the notch part 1
0, remove the elastic piece 3 from the engagement of the recess 4, and
All you have to do is slide the cutter 2 in the direction opposite to the arrow in the figure.

ツターの離脱を完全に防止することができる。<Effects> As explained above, according to the present invention, the cutter is prevented from coming off the cutter mounting member in the front-rear direction due to the contact between the side wall of the cutter and the cutter mounting opening, and the locking protrusion portion The cutter is prevented from coming off in the vertical direction by the locking piece of the cutter being locked with the locking protrusion of the mounting member, and furthermore, the cutter is prevented from coming off in the horizontal and upward directions with respect to the mounting member. The elastic piece of the cutter is prevented from coming off by engaging with the recess of the attachment member, and furthermore, the elastic piece of the cutter is prevented from coming off in the downward direction with respect to the attachment member by the engaging part of the cutter. This is prevented by engaging the notch in the side wall of the mounting member, so with a simple structure, it is possible to completely prevent the cutter from coming off when cutting the recording paper, due to vibration, external force, etc. .
