- in which the holding and moving means comprises:
- (i) a first supporting means rotatably supported by vertical plates therebetween and disposed in a direction perpendicular to the recording means scan, for supporting the supporting member with the curved surface at one end thereof,
- (ii) horizontal openings respectively formed in said vertical plates,
- (iii) a second supporting means connected at one end thereof to the other end of said first supporting means by a coupling means, for supporting the roller at the other end of said second supporting means, and
- (iv) pins affixed to said second supporting means and adapted to slidably move in said horizontal openings when said first supporting means is turned.
A recorder having a feed member and a take-up member positioned under stretched recording paper extending about a supporting member with a curved surface and a roller, the recording paper drawn out of a paper roll mounted on the feed member, progressively passing over the supporting member, the roller and being wound onto the take-up member, and the recorder having at least one recording means moving across the width of the recording paper, the improvments characterized by means for holding and simultaneously moving the supporting member and the roller so that at least one of the feed member and the take-up member can be removed and installed in the recorder from the upper side of the stretched recording paper,
- in which the holding and moving means comprises:
- (i) supporting means rotatably supported by vertical plates therebetween and disposed in a direction perpendicular to the recording means scan, for supporting the supporting member with curved surface at one end thereof,
- (ii) means rotatably supported around at least one of the axis of the take-up member and a point adjacent to the axis at one end thereof, for rotatably supporting the roller at the other end thereof, and
- (iii) a bar rotatably secured at an end thereof to the other end of said second supporting means (ii) and rotatably secured at the other end thereof to said first supporting means (i).
In a recorder having a feed member and a take-up member positioned under stretched recording paper extending about a supporting member with a curved surface and a roller, the recording paper drawn out of a paper roll mounted on the feed member, and progressively passing over the supporting member, the roller and being wound onto the take-up member, and the recorder having at least one recording means moving across the width of the recording paper, the improvement characterized by:
- (i) a first gear rotatably coupled to a vertical plate placed in a direction perpendicular to the recording means scan,
- (ii) a second gear rotatably coupled to the vertical plate and meshed with said first gear,
- (iii) a first supporting means affixed to said first gear at one end thereof, for supporting the supporting member with the curved surface at the other end thereof,
- (iv) a second supporting means affixed to said second gear at one end thereof, for supporting the roller at the other end thereof,

- (A) a lateral support plate with a horizontally extending slot;
- (B) a roller supported by a movable guide pin in the horizontally extending slot;
- (C) a vertical support member, and
- (D) a cover plate connected at one end to the roller and at the other end to the vertical support member,
- so that when said vertical support member is lifted vertically, said roller and guide pin move horizontally inwardly along said horizontally extending slot, and said cover plate is raised upwardly in the direction of said vertical support member.

- (B) a cover plate;
- (C) a first arm supporting said roller and connected to a second roller;
- (D) a second arm connected at one end to said first arm so that said roller is rotatable about said second roller, and connected at the other end to said cover plate;
- and
- (E) a horizontally-extending bar rotatably supporting said cover plate,
- so that when said cover plate is rotated about said horizontally-extending bar, said roller (A) is rotated in the opposite direction and toward said cover plate.
A device for changing paper in a recorder comprising:
- (A) a pair of cover plates, and
- (B) a pair of meshed gears, each gear connected to an end of a cover plate,
- so that when the gears are rotated in respective clockwise and counter-clockwise directions, the cover plates are rotated upwardly toward each other.
