The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is;
1. A magnetic tape cartridge comprising a cartridge casing formed by upper and lower casing halves, a single reel around which a magnetic tape with a leader pin fixed to the leading end thereof is wound and which is contained in the cartridge casing for rotation, and a spring member for removably holding upper and lower end portions of the leader pin on the cartridge casing,
wherein the improvement comprises that the spring member comprises upper and lower holding portions which are respectively brought into abutment against the upper and lower end portions of the leader pin and are connected to each other.
2. A magnetic tape cartridge as defined in claim 1 in which the spring member is symmetrical about both its horizontal and vertical axes.
3. A magnetic tape cartridge as defined in claim 1 in which the spring member is further provided with a pressing portion which urges the leader pin in its axial direction.
4. A magnetic tape cartridge comprising a cartridge casing formed by upper and lower casing halves, a single reel around which a magnetic tape with a leader pin fixed to the leading end thereof is wound and which is contained in the cartridge casing for rotation, and a spring member for removably holding at least one of upper and lower end portions of the leader pin on the cartridge casing,
wherein the improvement comprises that the spring member comprises at least one resilient pin holding member which is held in a position where it can resiliently engage with upper or lower end portion of the leader pin pinched by an end face of a spacer tube and upper or lower inner surface of the cartridge casing, the spacer tube being fitted on a support pin erected on the upper surface of the lower casing half in a height substantially equal to the space between the lower surface of upper casing half and the upper surface of the lower casing half.
5. A magnetic tape cartridge comprising a cartridge casing formed by upper and lower casing halves, and a single reel around which a magnetic tape with a leader pin fixed to the leading end thereof is wound and which is contained in the cartridge casing for rotation,
wherein the improvement comprises that a resilient member which is resiliently brought into abutment against one of the upper and lower end faces of the leader pin to removably hold the leader pin on the cartridge casing is provided on the upper or lower casing half.
6. A magnetic tape cartridge as defined in claim 5 in which said resilient member comprises a resilient arm member formed integrally with the upper or lower casing half.
7. A magnetic tape cartridge as defined in claim 5 in which said resilient member comprises a resilient arm member which is fixed to the upper or lower casing half at its one end.
8. A magnetic tape cartridge as defined in claim 5 in which said resilient member comprises an elastic projection member which is fixed to the upper or lower inner surface of the cartridge casing.
9. A magnetic tape cartridge comprising a cartridge casing, and a single reel around which a magnetic tape with a leader pin fixed to the leading end thereof is wound and which is contained in the cartridge casing for rotation,
wherein the improvement comprises that an elastic member is provided on at least one of upper and lower inner surfaces of the cartridge casing to be brought into abutment against the upper or lower end face of the leader pin and to press the leader pin in the axial direction thereof under its elasticity, thereby removably holding the leader pin in the cartridge casing.
10. A magnetic tape cartridge comprising a cartridge casing, and a single reel around which a magnetic tape with a leader pin fixed to the leading end thereof is wound and which is contained in the cartridge casing for rotation,
wherein the improvement comprises that an elastic member which urges upper and lower end faces of the leader pin to resiliently abut against the upper and lower inner surfaces of the cartridge casing is provided on at least one of the upper and lower end portions and the leader pin is removably held in the cartridge casing under the elasticity of the elastic member.
11. A magnetic tape cartridge comprising a cartridge casing, and a single reel around which a magnetic tape with a leader pin fixed to the leading end thereof is wound and which is contained in the cartridge casing for rotation,
wherein the improvement comprises that the leader pin comprises a main portion at which the magnetic tape is fixed to the leader pin and a pair of engagement portions which project from opposite ends of the main portion in the axial direction of the main portion and are brought into engagement with engagement portions formed in the cartridge casing, each engagement portion of the leader pin being rotatable about the longitudinal axis of the leader pin relative to the main portion.
12. A magnetic tape cartridge as defined in claim 11 in which each of the engagement portions of the leader pin is a substantially cylindrical member mounted for rotation on a support shaft which projects in the axial direction of the main portion coaxially with the main portion.
13. A magnetic tape cartridge as defined in claim 12 in which the support shaft is provided on its free end a larger diameter portion which is resiliently compressible in a radial direction and the engagement portion of the leader pin is supported for rotation on the support shaft by press-fitting the larger diameter portion in a recess having an inner contour conforming to the outer contour of the larger diameter portion.
14. A magnetic tape cartridge comprising a cartridge casing, and a single reel around which a magnetic tape with a leader pin fixed to the leading end thereof is wound and which is contained in the cartridge casing for rotation,
wherein the improvement comprises a pin holding member which is rotatable between a first position where, when the leader pin is retracted into the cartridge casing, the pin holding member is brought into abutment against the leader pin to be rotated to a second position where the pin holding member holds the leader pin in a predetermined position, the pin holding member being rotated to said first position by the leader pin to permit removal of the leader pin from the cartridge casing when the leader pin is drawn out.
