JPS58157656A - Detecting mechanism for skew insertion of unit slip - Google Patents

Abstract

PURPOSE:To enable an skew insertion of unit slip to be detected immediately by providing plurality of paper form-detecting sensors behind driving roller. CONSTITUTION:A unit slip 1 that is set on an inserting table 2 is inserted upward by means of rollers 3. At this time, the unit slip 1 passes over paper form- detecting sensors 5 and 6 which are arranged in a line along the driving rollers 3. If the inserted unit slip becomes skew, either one of two paper form-detecting sensors detects the paper form in advance to the other sensor. After thisk the other sensor detects the paper form with a delay of some pitches of the drive motor. Accordingly, a precise unit slip inserting operation can be achieved, eliminating erroneous insertion.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to prevention of skew insertion in a ticket insertion device that feeds tickets.

A conventional device of this type is shown in FIG. In the figure, f1] is a single sheet, (2) is a single sheet insertion table,
(3) is a ticket insertion drive roller, and (4) is a roller drive step motor.

Next, the operation will be explained. The ticket i1J set on the insertion table (2) is inserted upward by the drive roller (3).

Since the conventional ticket insertion mechanism is constructed as described above, there is a drawback that if a ticket is set in a bent state on the insertion table, it will be skewed and inserted upward.

This invention was made to eliminate the drawbacks of the conventional ones as described above, and by attaching a plurality of paper detection sensors behind the drive roller and utilizing the detection signal timing from each of these sensors, It is an object of the present invention to provide a ticket insertion mechanism capable of detecting skewed insertion.

An embodiment of the present invention will be described below with reference to the drawings. Second
In the figure, (1) is a ticket, (2) is a ticket insertion table, (3) is a ticket insertion drive roller, (4) is a roller drive step motor, (5) is a first paper detection sensor, and (6) is a ticket insertion drive roller. ) is the second paper detection sensor;

They are arranged at a predetermined distance (corresponding to the width of the inserted ticket) on a straight line indicated by a chain line that is perpendicular to the direction of travel of the ticket (arrow in the figure).

Next, the operation will be explained. The cut sheet +1 set on the insertion table (2) is inserted upward by the drive roller (3). At this time, they were placed on a straight line. A cut sheet passes over each paper detection sensor (5j (6)).

If the inserted ticket is skewed, one of the two paper detection sensors will detect the paper first. After that, the pitch drive motor is driven and the other sensor detects the paper.

When these two sensors detect a sheet, it is assumed that the sheet has been inserted obliquely, and the roller drive motor (4) reverses the roller (3) to eject the sheet and issue an instruction for reinsertion.

In the above embodiment, when it is determined that the sheet is inserted obliquely, the roller (3) is reversed to eject the sheet.
It may be configured such that a control signal is issued to prevent printing, and then the ticket is advanced in the forward direction and discharged to the outlet for printed tickets.

It was a cabinet. If oblique insertion is detected, the advance of the cut sheet may be stopped and the cut sheet may be ejected by an operator's operation.

However, it is best to place the sensors at a predetermined distance apart in a straight line perpendicular to the direction in which the sheets travel, as this makes it easier to determine the timing of each detection signal. , even if the sensors (5) and (6) are arranged at different positions as shown in Fig. 3, by taking the shift into account when determining the detection signal timing, the result will be the same as in the case of a straight line. Skew detection is possible.

As described above, according to the present invention, since the oblique insertion of a ticket can be detected by several sensors, there is an effect that a highly accurate ticket insertion operation without erroneous insertion can be performed.
