BACKGROUND OF THE INVENTION
The present invention relates to a page turning apparatus for booklet-like media .
[0002]
[Prior art]
Conventionally, page turning of a booklet-like medium such as a bank passbook is performed according to the procedure shown in FIG. That is, first, the binding portion side of the booklet-like medium is captured on the conveyance path by the conveyance roller pair, and then the pressure portion is projected on the conveyance path. As shown in FIG. 1, the booklet-shaped medium is bent upward as a result of the pressure portion projecting operation, and the turning direction surface of the page to be turned 1 a is in pressure contact with the page turning roller 2. In this state, the protrusion operation of the pressure unit 4 is stopped and the page turning roller 2 is rotated in the turning direction while maintaining the curved state. As the page turning roller 2 rotates, the page turning target page 1a moves toward the binding portion 1c due to friction with the page turning roller 2, so that the curvature of the page is reduced, and the page turning roller 2 is driven to rotate. If it continues, the free edge 1b will run over the page turning roller 2. FIG. After that, when the rotation of the page turning roller 2 is stopped and the booklet-like medium 1 is fed by the conveying roller pair 3, the page 1a to be turned falls on the opposite page with the binding portion 1c interposed therebetween, and the page turning operation is completed.
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional example, the turning operation by the page turning roller 2 is performed after the bending operation to the booklet-like medium 1 in the pressure unit 4 is completed, and thus there are the following problems. That is, the booklet medium 1 such as a bankbook has a different usage frequency, or the material, thickness, etc. of the booklet medium 1 are different, and the banks have rigidity (in order to use the booklet medium 1 of different materials). The strength of the waist is different. Even if only the pop-up height of the pressure unit 4 is managed under such conditions, the frictional force with the page turning roller 2 is not constant, and if the frictional force is too low, the turning operation cannot be performed. If is too large, a turning failure occurs in which the next page is turned together. In order to solve this problem, it is possible to change the pop-up height of the pressure unit 4 in accordance with the rigidity of the booklet-shaped medium 1, but in this case, a sensor or the like is required. Therefore, the structure is complicated.
[0004]
The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide a page turning apparatus for a booklet-shaped medium having a simple structure and high reliability in a turning operation.
[0005]
[Means for Solving the Problems]
According to the present invention, the object is
A pair of conveying rollers 3 that captures the binding portion 1c side of the booklet-shaped medium 1 on the conveying path and conveys the booklet-shaped medium 1;
A page turning roller 2 which is disposed at the free edge 1b of the page 1a to be turned of the booklet-like medium 1 and turns the page 1a to be turned;
A pressure roller 5a disposed below the page turning roller 2 to form a pair with the page turning roller 2 and retractable and returnable with respect to a conveying path;
It is disposed at an intermediate position between the pair of conveying rollers 3 and the page turning roller 2 and protrudes to the upper portion of the conveying path to bend the booklet-shaped medium 1 upward and press the page turning roller 2 in the turning direction surface of the page 1a to be turned. A pressure part 4;
The pressure roller 5a is retracted downward from the booklet-like medium 1 held on the conveyance path to release the pressing pressure toward the page to be turned 1a, and the page turning roller 2 is driven to rotate in the page turning direction. By being performed together with the operation of popping the pressure unit 4 onto the conveyance path, the pressure unit 4 pushes up the page 1a to be turned from the back surface, and the free edge 1b of the page 1a to be turned with respect to the page turning roller 2 as the amount of popping increases. By controlling the pressure unit 4 so that the pressing force of the sheet is gradually increased, the page 1a to be turned up is lifted, the pressure roller 5a is returned to the conveyance path, and conveyed by the page turning roller 2 and the pressure roller 5a. is achieved by providing a page turning apparatus of the booklet-like medium, characterized in that turn the pages of Jo medium 1 .
[0006]
A booklet medium 1 such as a bankbook is captured at an appropriate position on the conveyance path when performing a page turning operation. At this position, the booklet-shaped medium 1 is in a curved posture convex upward, and the vicinity of the free edge 1b of the page to be turned 1a is brought into contact with the page turning roller 2. The page turning operation is performed by using the frictional force between the page turning roller 2 and the page to be turned 1a. If the frictional force is too large, a large number of pages are turned. If the frictional force is too small, the page turning operation is performed. I can't do it.
[0007]
There is a relationship between the frictional force and the pressing force of the page 1a to be turned to the page turning roller 2 as the pressing force increases. On the other hand, in this type of apparatus in which a pressing force is applied to a contact portion with the page turning roller 2 by lifting the central portion of the booklet-like medium 1 by the pressure unit 4, for example, the pressing force can be directly managed. Furthermore, since the friction coefficient of the booklet-like medium 1 varies, it is generally difficult to calculate and apply an appropriate pressing force.
[0008]
The present invention has been made by paying attention to the fact that the above-mentioned difficulty is caused by the idea that an appropriate pressing force is already applied when the turning operation by the page turning roller 2 is started. The page turning operation according to 2 is performed together with the curving operation of the booklet-like medium 1, and the appropriate pressing force necessary for the page turning operation is automatically detected in the page turning operation process, thereby improving the reliability of the page turning operation. It is what raises.
[0009]
That is, in the present invention, when the curving operation of the booklet-shaped medium 1 is started, the turning target page 1a is pressed against the page turning roller 2, and the pressing force increases as the curvature of curvature decreases. On the other hand, since the page turning roller 2 is driven to rotate in the page turning direction during the bending operation, the page turning target page 1a is automatically moved when the pressing force is appropriate for page turning. Therefore, in the present invention, the pressing force necessary for the page turning operation is automatically detected without using any special detection means, and the reliability of the turning operation can be improved with a simple structure. Become.
