In the above-described conventional cartridge storage case, the locking springs 64 are each provided with a predetermined locking force with respect to the cartridge 61 in the limited space of the internal space 62 of the case body 60. It must be provided so that it can be obtained. Therefore, the complexity of the structure,
There is a problem that the number of parts and the number of assembling steps are unavoidably increased, and the cost is increased.

When the locking force with respect to the cartridge 61 is reduced due to deterioration of the locking spring 64 over time, the dimension of the opening 63 in the left-right direction in FIG. Since it is larger, there is a problem that the cartridge 61 is easily dropped from the case main body 60 through the opening 63 even by a slight external force or impact.

Further, when the contained cartridge 61 is detached, a part 61a of the cartridge 61 exposed from the case body 60 at the cutout portion 66 is grasped with a fingertip and pulled downward in FIG. Since the external dimensions are quite small, there is a problem that it is difficult to grip the cartridge 61 even with a fingertip, and good operability cannot be obtained. Similar problems existed when accommodating the cartridge 61.

According to the present invention, the cartridge can be securely held in the internal space while having a relatively simple structure, and good operability can be ensured when the cartridge is put in and taken out. It is intended to provide a cartridge storage case.
