Conventionally, as an example of a method for inserting and removing a cartridge into this information processing apparatus, both sides of the cartridge are inserted into and removed from the information processing apparatus. There is a method in which the cartridge is inserted into the cartridge by rollers provided in the cartridge, and the cartridge is inserted into and removed from the information processing apparatus by the rotational force of the roller.

However, in this method, slippage occurs between the roller and the cartridge, and in order to prevent this slippage, it is necessary to press the roller against the cartridge with a certain amount of pressure.

As a result, the information storage medium and the cartridge came into contact with each other, causing damage to the information storage medium. Additionally, this method requires rollers, transmission belts, shafts, etc. within the information processing device, and has the disadvantage of increasing the number of component parts.

Another method is to provide four parts on the side of the cartridge,
There is also a method that engages with a convex part on the information processing device side and slides the entire slide table on which the cartridge is placed, but even with this method, the mechanism and structure of the slide mechanism etc. are cluttered and the number of component parts is reduced. The disadvantage was that there were more
