Description

  The present invention relates to a roll-shaped recording medium support device and a support method, and more particularly, reduces the user burden when fixing the roll-shaped recording medium to a support member, and further reduces the user burden for various types of roll-shaped recording media. The present invention relates to a roll-shaped recording medium support device and a support method.

  In general, the recording medium includes a roll-shaped recording medium in which the recording medium is wound into a roll, in addition to a sheet-shaped recording medium that records each sheet. A roll-shaped recording medium is often used in a large-sized recording apparatus because the size for accommodating the recording medium can be reduced even when image recording with a large recording area is performed. At this time, the user sets the roll-shaped recording medium in the recording apparatus to perform the recording operation. However, the roll-shaped recording medium has many disadvantages because it is wound in multiple layers, and is set in a large-sized recording apparatus. However, since it is long and thin, there is a drawback in that handling is burdensome.

  Conventionally, apparatuses disclosed in Patent Documents 1 and 2 are known as roll recording medium setting apparatuses.

  The apparatus described in Patent Document 1 is an apparatus that puts a roll-shaped recording medium into a recess formed by both side plates and a winding roller at the bottom. This setting method is also called a throw-in method. In this apparatus, various widths of the roll-shaped recording medium can be handled by moving the side plate in the width direction of the roll-shaped recording medium by the slide groove. Further, since the sliding side plate presses the slide groove with a spring, the slide can be fixed by the frictional force between the side plate and the slide groove, so that the roll-shaped recording medium can be easily fixed.

However, in this apparatus, the roll-shaped recording medium is unwound from the bottom of the roll-shaped recording medium by the unwinding roller. However, if the friction between the unwinding roller and the roll-shaped recording medium is small, unwinding cannot be performed satisfactorily and The problem of loosening of the recording medium occurs, and this apparatus has a drawback that the problem of loosening is likely to occur because friction with the roll- shaped recording medium is obtained by the weight of the unwinding roller. Further, since the roll recording medium is fixed by the user himself / herself, there is a disadvantage that a burden is imposed on the user.

  Next, the apparatus described in Patent Document 2 supports a roll-shaped recording medium by fitting a support member from both ends into the hollow portion of the roll-shaped recording medium and suspending the support member from both ends. . This apparatus can reduce the burden on the user because it is only necessary to fit the support members to both ends of the roll-shaped recording medium.

However, when using this apparatus, since the user needs to hold the roll-shaped recording medium with one hand, there is a disadvantage that the user becomes unstable and places a burden on the user. In addition, since a support member corresponding to each width is required for various widths of the roll-shaped recording medium, it is inconvenient for the user, and there is a disadvantage that a burden on the user is applied.

The hollow portion pressing member 300 is composed of about four to eight wing-shaped members and is fixed around the tip of the pressing shaft 301. Since the wing-like member is fitted in and supported by the roll hollow portion 100, it is preferable to have a shape that is easy to insert and difficult to remove. For this purpose, it is preferable to have a leaf spring function such that elasticity acts in a direction away from the outer periphery of the pressing shaft. Due to the presence of the hollow portion pressing member, it is possible to reliably support the roll-shaped recording medium simply by placing the roll-shaped recording medium on the temporary placement portion, thereby reducing the burden on the user.

  As shown in FIG. 7, slide rollers 603 and 603 provided at the tip of the shaft 602 fixed to the mounting plate 5 are mounted in the groove 601 of the slide groove member 600. As the slide rollers 603 and 603 roll along the slide groove 601, the roll recording medium 1 slides in the width direction (horizontal direction in the drawing), and accordingly, the hollow portion pressing member 3 can be moved horizontally.

  The fixing means 6 is provided on the side surface of the mounting plate 5, and an example of the structure will be described with reference to FIG. As shown in FIG. 8, a slide stop clamp 604 is provided. When unclamping, the slide stop clamp 604 is opened as shown in FIG. 8A, and when clamping, the tip of the clamp is slid as shown in FIG. 8B. The groove 601 is pressed against the inner surface, and the horizontal movement of the hollow portion pressing member 3 is stopped by the frictional force. By stopping by the slide stop clamp 604, it becomes possible to support roll-shaped recording media of various widths.

  The fixing means 6 preferably has a mechanism for fixing the roll hollow portion 100 in a state where the hollow portion pressing member 3 is fitted. In this case, the state where the hollow portion pressing member 3 is fitted is counted by a timer (not shown) that drives the pressing drive means, or the position of the pressing shaft by an optical or contact type (not shown), This can be confirmed by detecting the deflection of the hollow portion pressing member due to electrical strain measurement.

  Next, a control system used for the apparatus of the present invention will be described.
