Abstract
An image recording apparatus in which a photosensitive material is rewound into a magazine while maintaining a predetermined disposition. Prior to rewinding of the photosensitive material, a distance between concave portions of guide members which constitute a guide portion is set to be substantially equal to the photosensitive material width and a nipping state between a pair of pulling-out rollers is cancelled. Because the nipping state is cancelled, the photosensitive material can be displaced in a width direction. Therefore, the photosensitive material can be rewound into the magazine while maintaining the predetermined disposition, and any skew is corrected by the concave portions of the guide members.
Claims15
An image recording apparatus in which an image is formed by exposing a photosensitive material, the apparatus comprising:
- a magazine for accommodating the photosensitive material in a light-shielded state;
- a pair of rollers which nip and pull out the photosensitive material from the magazine to inside the apparatus;
- a widthwise guide which is disposed in a vicinity of the pair of rollers and which restricts a rewinding direction of the photosensitive material by engaging edges of the photosensitive material at a time of rewinding of the photosensitive material;
- and
- a restriction canceling mechanism for canceling a width direction restriction of the photosensitive material due to the pair of rollers;
- wherein, when the photosensitive material is to be rewound into the magazine, the restriction of the photosensitive material due to the pair of rollers is cancelled by the restriction canceling mechanism, and a guide width defined by the widthwise guide is made narrower than when the photosensitive material is being pulled out.
An image recording apparatus in which an image is formed by exposing a photosensitive material, the apparatus comprising:
- a magazine for accommodating the photosensitive material in a light-shielded state;
- a pair of rollers which nip and pull out the photosensitive material from the magazine to inside the apparatus body;
- a widthwise guide which is disposed in a vicinity of the pair of rollers and which restricts a rewinding direction of the photosensitive material by engaging edges of the photosensitive material at a time of rewinding of the photosensitive material;
- and
- a restriction canceling mechanism for canceling a width direction restriction of the photosensitive material due to the pair of rollers;
- wherein, when the photosensitive material is to be rewound into the magazine, the restriction of the photosensitive material due to the pair of rollers is cancelled by the restriction canceling mechanism, and a guide width defined by the widthwise guide is set such that skew of the photosensitive material can be corrected.
A method for rewinding photosensitive material in an image recording apparatus that has a magazine for accommodating the photosensitive material in a light-shielded state, a pair of rollers which nip and pull out the photosensitive material from the magazine to inside the apparatus, a widthwise guide which is disposed in a vicinity of the pair of rollers and which controls a rewinding direction of the photosensitive material by engaging with edges of the photosensitive material during the rewinding of the photosensitive material, the method comprising the steps of:
- canceling a width direction restriction of the photosensitive material due to the pair of rollers;
- making a guide width defined by the widthwise guide narrower than when the photosensitive material is being pulled out;
- and
- rewinding the photosensitive material.
