JPS63208461A - Roll paper take-up device of electronic record calculator - Google Patents

Abstract

PURPOSE:To take up orderly a printed roll paper always for reuse by constituting a take-up portion in contact with the rotating roll paper to rotate so that the printed roll paper is taken up orderly. CONSTITUTION:A take-up bar 1 and rotational direction converting bar 3 are operated vertically by arm grooves. Said bar 3 is put from the upper grooves of take-up arms, and then the take-up bar 1 is put into a roll paper take-up core 2 from the upper groove of take-up arm. After an end of roll paper 4 makes contact with said core 2, records are calculated. And the back of taken-up roll paper is used and taken-up orderly.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention is equipped with a winding part at the end of a roll paper arm, and conventionally, roll paper with printed information for electronic recording calculators has no winding part, so it can be placed on a desk. They were often left in piles of garbage, and once used for printing purposes such as temporary confirmation, they were often thrown away.

Therefore, in order to avoid problems such as the waste of disposable paper and tidying up the desk, it is recommended to roll up and organize the printed roll paper so that it can be reused at any time. is important, and this request was solved in a simple way.

To explain the structure, the winding rod (1) and rotational direction changing rod (3) are moved up and down by arm grooves. Insert the rotation direction changing rod (3) from the upper groove of the winding arm, then insert the winding rod (1) into the roll paper winding core (2) and insert it from the second side of the winding arm.

Recording calculations are performed after gluing the tip of the roll paper to the roll paper winding core.

As another example, by giving weight to the winding rod, rotation transmission can be stabilized by the weight, and by making the surface of the rotation direction changing rod of rubber, rotation transmission can be made accurate. Also, depending on the rotation direction of the roll paper, the rotation direction changing rod can be omitted by bringing the winding portion into direct contact with the rotation of the roll paper as shown in FIG.

Figure 6 shows the case of a calculator that cannot be used due to damage to the arm, but can be used without repair by setting it at the bottom of the computer.

As an effect of the invention, paper can be saved by reusing the roll paper by using the back side of the rolled paper or by overprinting, and by organizing the roll paper, the desk is kept tidy during calculations. , there is no chance of getting twisted paper involved. In addition, the printed information is easy to see without having to hold the printed roll paper with your hands, which is convenient.
