Magnetic recording and reproducing apparatus with tape extraction

Claim 2

A magnetic recording and reproducing apparatus comprising: a guide drum including a magnetic head; take-out means for taking a tape out of an opening of a cartridge into a narrow loop; spreading means for spreading said narrow loop of the tape into a wide loop; and tape guiding means including at least one tape guide pin which is inserted into the wide loop of the tape, and guide pin moving means on which said pin is mounted and movable around said guide drum to guide the tape into contact with and to hold it against a portion of the periphery of the guide drum, whereby said tape guide pin serves as a guide for positioning the tape in a predetermined path while the tape is moving along said guide drum.

Claim 3

A magnetic recording and reproducing apparatus as claimed in claim 1 wherein, saiD tape guiding means includes a plurality of guide arms, each of which has a tape guide pin fixed to one free end thereof respectively, and each being mounted for swinging movement around said guide drum between a first position and a second position to guide the tape against a portion of the periphery of the guide drum, in the first position said guide arms being close to each other with the tape guide pins side by side so that said guide pins can all be inserted in the spread loop of the tape at one time, and in the second position said guide arms being apart from each other for positioning the tape guide pins separately around the guide drum.

Claim 4

A magnetic recording and reproducing apparatus as claimed in claim 2 wherein, said tape guide means further comprises drive means coupled to a first one of the tape guide arms for first moving the tape guide pin on said first tape guide arm around the guide drum to guide the tape around the periphery of the guide drum at first, and coupling means for coupling the guide arms for moving the other guide arms with the other tape guide pins around the guide drum following said tape guide pin on said first tape guide arm successively to guide the tape at the second position spaced from the tape against the periphery of the drum to prevent the portion of the tape against the periphery of the guide drum from being touched by the remainder of the tape in the spread loop.

Claim 5

A magnetic recording and reproducing apparatus as claimed in claim 3 wherein said coupling means comprise pins on each of the other guide arms and pin engaging edges on said first guide arm spaced to engage said pins at points spaced along the movement of said first guide arm.

Claim 6

A magnetic recording and reproducing apparatus as claimed in claim 1 wherein, said take-out means comprises a movable take-out pin means including a take-out pin movable for taking the tape out of the cartridge in a narrow loop, and said spreading means comprises a swingable arm having a spreading pin thereon and movable to insert said spreading pin into said narrow loop of tape and to spread the tape into a wide loop.

Claim 7

A magnetic recording and reproducing apparatus as claimed in claim 5 in which said swingable arm is swingable vertically to insert the spreading pin into the narrow loop of the tape, and is swingable horizontally to spread the tape into the wide loop during the movement of said take-out pin means.

Claim 8

A magnetic recording and reproducing means as claimed in claim 6 in which swing means is connected to said swingable arm for urging said swinging movements, and said take-out pin means further comprises a carriage on which said take-out pin is mounted and movable in a straight line, and a stop pin on said carriage engaging said swingable arm and restraining said arm until said carriage has moved a predetermined distance to form said narrow loop of tape.

Claim 9

A magnetic recording and reproducing apparatus as claimed in claim 5 wherein, said take-out pin means further comprises a carriage on which said take-out pin is mounted, a lead screw on which said carriage is mounted for movement along a straight line by the rotation of the lead screw.
