Abstract

PURPOSE:To effectively prevent the generation of jamming by operating a paper turning-over guide mechanism on the basis of the output signal from a booklet width detection sensor to guide the same to a position predetermined corresponding to the width of a booklet. CONSTITUTION:A plurality of booklet width detection sensors 4, 5, 6 are provided on the booklet inserting side of a booklet guide 3 and the booklet 3 fed along a booklet guide 2 by a booklet feed roller 1 is detected by the sensor 4 and the width of the booklet is immediately discriminated on the basis of the output signals of the sensors 4, 5, 6. A page turning-over guide mechanism 7 is moved on the basis of the discrimination result by an actuator 9 so as to be capable of guiding the center of the width of the booklet 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a booklet pre-turning device for printers, and particularly to a booklet page-turning device suitable for use in terminal devices for financial institutions.

[Conventional technology]

Conventionally, in this type of booklet page turning device, the page turning position was always at a fixed position even for booklets with different widths.

[Problem to be solved by the invention]

In the conventional booklet page turning device described above, the position of the turning guide is constant regardless of the width of the booklet, so it is not possible to guide the center of the booklet when turning the pages, and if the booklet is in poor condition, the page to be turned may become jammed. There was an inconvenience.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a booklet page-turning device for a printer that can improve the inconveniences of the conventional example and, in particular, can significantly reduce the occurrence of jamming when turning the pages of a booklet. It is something.

[Means for Solving the Problems] The present invention includes a booklet guide that guides the movement of a booklet that is urged by a booklet conveyance roller, and a page suction device that is installed at the destination of the booklet and that operates as necessary. In a booklet pre-turning device for a printer, which includes a page-turning mechanism and a page-turning guide mechanism that is activated when the page suction mechanism moves a predetermined distance and starts a page-turning operation for each suctioned page, the booklet insertion side of the booklet guide is Equipped with a plurality of booklet width detection sensors and a page turning movement mechanism that operates based on the output signal from the booklet width detection sensor and guides the page turning guide mechanism to a predetermined position according to the booklet width. It has this configuration.

This aims to achieve the above-mentioned purpose.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

The embodiment shown in FIGS. 1 to 4 includes a booklet guide 2 that guides the movement of the booklet 3 that is urged by a booklet conveyance roller l, and a booklet guide 2 that is installed at the destination of the booklet 3 that is sent in as required. The present invention includes a page suction mechanism 11 that operates when the page suction mechanism 11 operates for a predetermined distance, and a page turning guide mechanism that operates when the page suction mechanism 11 operates a predetermined distance and enters a page turning operation for the suctioned page. The booklet insertion side of the booklet guide 3 is equipped with a plurality of booklet width detection sensors 4, 5.6.

A page turning movement mechanism 10 is provided which operates based on output signals from the booklet width detection sensors 4 to 6 and guides the page turning guide mechanism 7 to a predetermined position according to the width of one booklet.

To explain this in more detail, the conveyance path along which the booklet 3 is conveyed includes a booklet width detection sensor 4. Sensor 5 and sensor 6 are mounted. The page turning movement mechanism 10 is equipped with a turning guide mechanism 7 via a guide shaft 8. The page turning guide mechanism 7 is driven by an actuator 9. or,
A page suction mechanism 11 for placing a turned page on a page turning guide mechanism is movable in the vertical direction by an actuator (not shown). Reference numeral 11A indicates an adsorption pad.

Next, the operating principle of the above embodiment will be explained.

The booklet 3 conveyed along the booklet guide 2 by the booklet conveyance roller 1 is detected by the sensor 4 . First, the booklet conveyance roller 1 is controlled to stop. Then immediately sensor 4. The booklet width is determined based on the output signals of the sensor 5 and the sensor 6. Based on the determination result, the page turning guide mechanism 7 is moved by the actuator 9 so that it can guide the center of the width of the booklet 3. Next, the suction pad IIA is lowered by the actuator, and when the turned page of the booklet 3 is suctioned, it is raised again. When the turned page passes through the page turning guide mechanism 7,
The suction is released, and the turned page is placed on the turning guide mechanism 7. Further, the booklet 3 is conveyed by the booklet conveyance roller 1, so that the pages thereof are turned over.

FIG. 4 shows a front view of a wide booklet. The booklet 3 conveyed by the booklet conveyance roller 1 is stopped by the sensor 4 . The width of the booklet is determined based on the output signals of the sensor 5 and the sensor 6, and the turning guide 7 is moved by the actuator 9 so that it can guide the center of the width of the booklet 3.

〔Effect of the invention〕

As explained above, according to the present invention, by controlling the guide position of the booklet page turning guide mechanism to always be located at the center of the booklet according to the width of the booklet, it is possible to always guide the center part of the page to be turned. It is possible to provide an unprecedented and superior printer book pre-cutting device that can reduce the inclination of pages and effectively prevent the occurrence of jams.
