a side door that slides along the sidewall provided with the first opening to open and close the first opening;
an extension arm formed substantially in a middle section of a front end portion of the slide door; and
a second opening formed substantially in a middle section of an end portion of the sidewall for receiving the extension arm when the first opening is closed,
wherein at least one of a lower half portion and an upper half portion of the end portion of the sidewall, which is respectively below and above the second opening, is provided with a hole portion that receives a projection formed on the front end portion of the slide door when the first opening is closed.
3. A magnetic tape cartridge comprising:
an opening through which a magnetic tape is drawn out, the opening being provided in part of a sidewall of a cartridge case across a lower half and an upper half of the cartridge case; and
a slid door that slides along the sidewall provided with the opening to open and close the opening,
wherein, recessed within at least one of a lower half portion and an upper half portion of the sidewall, is provided means for preventing the slide door from falling in a direction towards an inside of the cartridge case and a direction towards the outside of the cartridge case, when the opening is closed,
wherein the cartridge case contains a lower guide groove for accommodating a lower portion of the slide door for sliding the slide door to open and close the opening, the lower guide groove extending to and abutting the sidewall.
4. The magnetic tape cartridge according to claim 1 , wherein the holding concave portion has a substantially rectangular cross-section.
5. The magnetic tape cartridge according to claim 1 , wherein the holding concave portion has a substantially U-shaped cross-section.
6. The magnetic tape cartridge according to claim 1 , wherein the holding concave portion has a substantially V-shaped cross-section.
7. A magnetic tape cartridge comprising:
an opening through which a magnetic tape is drawn out, the opening being provided in part of a sidewall of a cartridge case across a lower half and an upper half of the cartridge case; and
a slide door that slides along the sidewall provided with the opening to open and close the opening,
wherein at least one of a lower half portion and an upper half portion of the sidewall is provided with a holding concave portion that holds a front end portion of the slide door from both sides thereof when the opening is closed,
wherein the holding concave portion is recessed within the sidewall,
