Description

[Detailed description of the invention] This invention is designed to ensure the stability of the drawing device itself when operating the drawing device that reduces or enlarges original drawings, or transfers them onto other paper surfaces while remaining on the moped. This invention relates to a fixing device for stabilizing original paper and transfer paper on a desk and making transfers without errors.

Conventionally, a drawing device makes various complicated movements on a desk, and the base of the device needs to be stably supported in the center of the desk, but it is difficult to maintain a stable state. At the same time, it is difficult to ensure the stability of the positional relationship between the base paper, the transfer paper, and the transfer device, and since this cannot be ensured, errors in transfer are likely to occur based on this, and the use of the transfer device is difficult. However, it was determined that there were serious shortcomings.

However, in the present invention, in order to securely attach the drawing device fixing rod to which the original paper support part and the transfer paper support part are attached as accessories of the drawing device to the end of the desk, it is possible to stably and It has been made easy to install, enables stable operation, and prevents errors when using a drawing device, and eliminates unavoidable drawbacks when using a drawing device. The effect is truly great, and it can be said that it was a success.

To explain in detail with reference to the attached drawing which shows an example of implementation, 1 is a U-shaped curved part, and the base end of the fixed rod 8 is curved in a U-shape, into which the end of the desk 9 can be inserted. It was made in a similar manner. 3 is a screw rod, which is screwed upward into the lower piece 2 of the U-shaped curved portion, and when rotating in the screwing direction, a bolt 3 is rotatably attached to the upper end of the screw rod 3.
The end of the desk 9 is clamped from above and below by the upper surface of a and the lower surface of the upper piece 12 of the U-shaped curved portion. Reference numeral 4 designates an abutting rod, which is fixed to the descending piece 10 of the U-shaped curved portion 1 in a direction perpendicular to the descending piece 10, that is, in a direction parallel to the end surface of the desk 9, with a stud 11; 4 is fitted so that the inner surface of the U-shaped curved portion 1 pinches the end of the desk 9, and when the screw rod 3 is tightened to the desk 9, both ends 4a and 4b of the corresponding rod 4 are tightly attached to the end surface of the desk 9. The screw rod 3 of the fixed rod 8 is prevented from rotating during operation, and the base end of the fixed rod 8 is fixed and stabilized relative to the desk 9, which is extremely simple, inexpensive, and
It is lightweight and allows the fixing rod 8 to remain stationary, allowing for good operation without error during the transfer operation, which is highly effective. 5 is a support part of the base paper for transfer a, 6
is a supporting part of the transfer paper b and is fixed at the middle part of the fixing rod 8. Reference numeral 7 denotes a drawing device mounting member, which is a protrusion protruding from the tip of the fixing rod 8, and is fitted into the mounting hole of the drawing device. The present invention has the above-mentioned configuration, and the fixing rod 8 of the present invention has its base end attached to the end of the desk 9 and the U-shaped curved portion 1 and the abutment rod 4.
Since they are brought into contact with each other in a cross shape and tightened with screw rods 3, the fixing rod always remains in a fixed state during the transfer operation, and the transfer device attached to it, the base paper, the transfer paper, etc. It is highly effective because it can ensure immobility in each individual or mutual relationship, allowing accurate transcription without errors.

Note that the abutment rod 4 is the descending piece 1 of the curved portion 1 of the fixed rod 8.
It may be fixed straightly on the inner surface of the descending piece 1.
A curved shape may be fixed to the outer surface of 0 as shown in the figure, and this should be carried out arbitrarily.
