However, in the above-described conventional handwritten handwriting input device, if a ring binder or the like that obstructs ultrasonic waves or infrared rays is inserted between the transmitter and the receiver, the ultrasonic signals and infrared signals emitted from the transmitters are transmitted. Since it is blocked and the receiving device cannot detect the position coordinate data, in the file notebook or system notebook that binds a plurality of notebook papers using a ring binder, it is necessary to provide a receiving device on both the left and right, or It is necessary to fix the receiving device to the page to be written every time the page changes. In addition, when the receiving device is fixed to a writing target page, there is a problem in that the area that can be written is narrowed because the receiving device occupies a certain range of the notebook paper.
Furthermore, as another method, it is conceivable to install a receiving device on a simple underlay that does not have a notch that matches the vertical width of the ring binder, and sandwich the underlay under the page to be written. When using this method, the underlay is shifted during writing and the distance between the receiving device and the paper changes, resulting in an error in the position coordinate data of the pen, and the recognized handwriting data is actually written on the paper with the pen There was a problem that the error was larger than the figure.

Paper underlay that can be equipped with a writing instrument including an ultrasonic transmitter and an infrared transmitter, the ultrasonic transmitter, an ultrasonic signal transmitted from the infrared transmitter, and a receiving device for receiving the infrared signal A ring binder for notebook paper that uses a handwriting handwriting input device that continuously transmits ultrasonic signal and infrared signal from the writing tool to the receiving device, and position coordinate data of the writing device to obtain handwritten handwriting data. In addition, an inverted V-shaped notch is provided on both the left and right improvement sides of the underlay, and a concave notch is provided on both the left and right sides of the underlay, and a ring portion for loading the ring binder note paper is provided. The present invention proposes a handwriting handwriting input device that allows the inverted V-shaped notch and the concave notch to be mounted on both the left and right sides.

In the present invention, it is possible to use the receiver without installing the receiver on both the left and right sides of the ring binder or fixing the receiver to the writing target paper every time the page to be written moves. In addition, by fixing the underlay of the present invention to the ring binder, the positional relationship with the notebook paper bound to the ring binder is small, so the position of the receiving device is shifted during writing, and the recognized handwriting data However, it is possible to overcome the problem that the error is larger than the characters and figures actually written on the paper with a pen.
Furthermore, in the present invention, a plurality of notebook papers bound to a ring binder can be easily mounted directly under a page to be written and can be written on the entire surface of the set notebook paper.

  A pen that emits ultrasonic waves and infrared rays, and an ultrasonic wave emitted from a pen that generates ultrasonic waves and infrared rays on an underlay provided with notches that match a ring binder included in a general file note on both sides A receiving device for receiving infrared rays is installed, and the underlay is configured to be detachable on both the left and right sides of the ring binder while the notebook paper is bound to the ring binder.

    The details of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a handwritten handwriting input device of the present invention. The handwritten handwriting input device of the present invention includes an underlay 1 and a pen 2. The underlay 1 is made of a material having flexibility and strength that can be used as an underlay.
