Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of an inner wrapping drum device in an optical character reading device or the like.

In optical character reading devices, etc., a rotating drum system with a high scanning speed is used, but in order to make it easier to attach a data sheet to the drum device, a drum device with an internal wrapping method has been proposed. There is.

(Patent Application No. 57-87763, Patent Application No. 57-57177
Figures 1 and 2 are explanatory diagrams of a conventional internal winding type drum device. In the drawings, reference numeral 4.5 indicates a pair of short cylindrical guide cylinders with a bottom. The bottom centers of the guide tubes 4 and 5 are fixed to the drum shaft 11, and the guide tubes 4 and 5 are arranged so that their open ends are opposed to each other.

Further, a part of the peripheral wall of the guide cylinders 4 and 5 is cut out in the axial direction to form an insertion opening for the data sheet 8, and at the end of the insertion opening there is a hole for guiding the data sheet 8 into the guide cylinder. A guide board 1 is arranged.

The data sheet 8 is inserted into the insertion opening while being guided by the guide plate 1, and is wrapped around the guide tubes 4, 5 by a pair of winding rollers 3 and a pressure roller 9 attached to the inner circumferences of the guide tubes 4, 5. inner peripheral surface and drum shaft 11
It is conveyed along the gap formed between the inner guide plate 10 attached to the inner guide plate 10, and its tip is applied to the Tekke Stocher 2VC.

In this state, when the data sheet 9 is wrapped by clamping the roller 3, the data sheet 9 is attached to the inner peripheral surfaces of the guide tubes 4 and 5 in an arc shape.

The winding roller 3 is driven by a motor (not shown) attached to the guide cylinders 4, 5 or the inner guide plate 1oVC.

However, with the conventional inner-wrapping type drum device as described above, it is possible to load only a certain length of data sheet, but if the length of the data sheet becomes short, the data sheet will be attached to the stopper. The data sheet is removed from the winding roller 1 before being applied to the data sheet 1, making it impossible to attach the data sheet.

The purpose of this invention is to improve the conventional internal wrapping type drum device and provide a simple mechanism that allows data sheets of different lengths to be attached.
The feature of this system is that it is possible to load paper sheets of various lengths by adding multiple sets of data sheet feeding rollers to the conventional internal winding type drum device.

An embodiment of the present invention will be described below with reference to the drawings.

Incidentally, the same members as those in the conventional drum device are given the same reference numerals, and the description thereof will be omitted.

FIG. 3 is a side view of the drum device according to the present invention, and numerals 6 and 7 are winding rollers added in the present invention, and the winding rollers 6 and 7 are similar to the winding roller 3. They are arranged at a predetermined interval on the inner circumferences of the guide tubes 4 and 5, and are connected to a motor that drives the winding roller 3 by a pulley (not shown) or the like.

By preparing multiple sets of winding rollers in this way, for example, even if a short data sheet falls off roller 3, the paper will be fed by roller 6, and even if it falls off roller 6, roller 7 will continue to feed the paper. sent away,
A data sheet having a length of 1 can be wrapped around the application stopper 2 and the roller 1.

As explained above, by using the mechanism of the present invention, it is possible to attach data sheets of various lengths, and together with the advantage of the internally wrapped drum, the effect of using it in optical character reading devices etc. Extremely large.

Claims (1)

[Scope of utility model registration request] The center of the bottom of a short cylindrical guide tube with a bottom is fixed to both ends of the rotating shaft, with the open ends facing each other, and a part of the peripheral wall of each guide tube is cut out in the axial direction to form a data sheet insertion slot. None, and furthermore, the guide tube is designed to transport various data sheets of different lengths inserted into the guide tube from the insertion opening along the inner circumferential surface of the guide tube and to make them come into contact with the inner circumferential surface of the guide tube. An inner wrapping drum device characterized in that a plurality of wrapping rollers are arranged at predetermined intervals on the inner circumference.
