[0003]

In the roll paper support of the example described in the prior art, the support portions of the shafts at both ends are fixed, and when a roll paper having a small width is used, the roll paper is placed horizontally. Since it may move and cause a failure, it can only be used for roll paper of one type width, and when using roll paper of multiple widths, it was necessary to prepare a support for multiple roll papers. . Further, a large-sized plotter that fits the maximum paper width that may be used is sometimes used. In addition, when using only one roll paper support, a blank having a small width was drawn and then the margin was cut off and discarded.

An object of the present invention is to provide a roll paper support that can accommodate roll papers of various paper widths and a plotter using the same.

SUMMARY OF THE INVENTION The present invention is a roll paper pedestal capable of supplying roll paper while preventing the roll paper from moving with support plates at both ends of a roll paper shaft which is passed through a roll paper winding hole. A rail having a plurality of recesses on both side surfaces at positions matching the widths of a plurality of roll papers, a guide guided by the rails, and a lock mechanism having a spring property and capable of fitting with the recesses are a structure integrated with a support plate, The recess of the rail is a notch provided on the inner side surface of the rail in a direction perpendicular to the movable direction of the support plate, and the lock mechanism is provided at the tip of a cantilever forming a part of the support plate and is a protrusion capable of fitting with the recess. In this structure, the projection is separated from the recess by the movement of the knob provided on the beam, and the support plate can be moved.

Further, according to the present invention, there is provided a roll paper pedestal capable of supplying the roll paper while preventing the roll paper from moving by the support plates at both ends of the roll paper shaft which is passed through the roll paper take-up hole. Rail, a support plate that can move in one axis in the rail, a handle that can rotate around the rotating part that is fixed to the supporting plate, and the center of the two rotating parts that are fixed to the supporting plate It is composed of a guide plate and a lever that can be rotated, and the rail has multiple recesses on both sides that fit the width of multiple roll papers.The support plate has a guide guided by the rail and a roll paper shaft support part. The handle has a mechanism that can rotate the guide plate and a mechanism that can hold the free end of the handle in two upper and lower positions.The guide plate has an end that enters the recess and a guide that rotates the lever in the opposite direction of the guide plate. , The lever is a recess on the side opposite the guide plate It has a structure with an end to enter, and the guide plate rotation mechanism of the handle is a set of a shaft and a long hole provided for each handle and guide plate, and the position holding mechanism of the handle has one end connected to the support plate and the other. The structure has a structure in which the end is connected to the handle, and the fine rotation of the handle causes the spring to be free in two positions beyond the rotating part of the handle, and the convex portion can be fitted and separated from the concave portion.

Further, the present invention provides claims 1 to 4.
The plotter is provided with the support according to any one of 1.

[0008]

According to the present invention, a pair of a plurality of recesses provided on the rail can be fitted with a lock mechanism having a spring property to position the support plate, and the lock property can be released by utilizing this spring property.
The support plate can be moved using the guides of the rails, and the width of the roll paper can be accommodated. This locking mechanism can be configured by a convex portion provided at the tip of the cantilever and a notch in the rail.

Further, according to the present invention, the recessed portion of the rail and the end portion of the guide plate / lever are fitted by the rotation transmission of the handle / guide plate / lever and the two-position holding function which are almost integral with the support plate.
It can be separated and the support plate can be moved using the guide of the rail. This rotation transmission is achieved by the shaft and the elongated hole, and the two-position holding function can be achieved by expanding and contracting the spring by circularly moving one end of the spring in the free state.
