Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a public telephone or the like used by an unspecified number of people, and more particularly to a telephone incorporating a panel having a memo function.

[0002]

2. Description of the Related Art As a memo function of a conventional telephone, a memo sheet is generally placed and written on the memo sheet. However, paper is limited, and the user has to carry extra paper, and the paper runs out in a short period of time.

[0003] In addition, a method of electrically recording data by using a semiconductor IC or the like is also used in a part of portable telephones and home telephones.
There were problems with confidentiality and maintenance.

[0004]

When a call is made, a memo sheet is usually set up and used when necessary. However, in a public telephone box or the like, these memo sheets are used in a short period of time, and the memo sheets are used up. Also, note papers are often discarded at the place after use, which is a problem.

Accordingly, it is an object of the present invention to remedy these drawbacks and to provide a telephone with a memo panel integrated with the telephone.

[0006]

The telephone according to the present invention is an integrated telephone having a panel having a memo function. Here, the panel having a memo function is characterized in that microcapsules are arranged on a thin flat surface, and a panel whose surface is covered with a transparent sheet is used to easily write characters and the like using a magnetic pen. It is.

Further, as a method of erasing the contents of the entered memo, at least one of the following methods is used for initialization.

First, there is a method of initializing microcapsules by sweeping the panel surface using a strip-shaped plastic magnet. Secondly, when the telephone is terminated and the handset is put on the telephone, an electric signal is generated, which triggers a signal that the telephone conversation is completed, and generates a magnetic field by energizing the electromagnet on the back of the panel. It is a method of initializing.

The microcapsule system used in the telephone of the present invention has been proposed (for example, see Japanese Patent Laid-Open No.
No. 143225) for the telephone of the present invention. That is, the microcapsule system of the telephone according to the present invention has a form that can be mounted on the telephone, and additionally has a practical initialization function.

In the panel of the present invention, a large number of microcapsules in which fine particles of a magnetic substance are sealed in a highly transparent plastic having a diameter of about 100 μm or less are densely arranged within a necessary range on a flat panel plate. Further, it is covered with a transparent sheet of plastic or the like to form a panel.

The magnetic fine powder magnetic needle in the microcapsule is
Usually, it is already known that the transparency inside the microcapsule is extremely low in the horizontal magnetic needle direction, and the transparency is increased by changing the magnetic needle direction vertically using a magnetic pen or the like, so that characters and figures can be displayed. ing.

When writing a memo, a magnetic pen attached to the telephone is used to change the direction of the magnetic needle from the horizontal direction on the panel to the direction of the vertical magnetic needle in the microcapsule at the required location on the panel. In this case, the color of the background plate on the lower surface of the panel is exposed on the surface so that characters and the like can be expressed.

The direction of the magnetic needle naturally changes in the horizontal direction due to its own gravity, but it requires time. Forcibly changing the horizontal direction can be freely performed by controlling the direction of the magnetism applied from the outside. As a part of the present invention, there is a method using an external magnet or a method of generating magnetism by an electric signal and using the magnetism.

If this panel is installed on a flat surface such as a front surface or a top surface of a public telephone, etc., and is integrated with the telephone so that it cannot be generally removed, a surface on which nothing is written when making a call at all times is always provided. Can be maintained.

That is, the present invention is a telephone with a memo function provided with a panel having a memo function constituted by a microcapsule, a magnetic pen, and a transparent sheet.

The present invention is also a telephone in which the panel is formed by arranging microcapsules on a thin flat surface and covering the surface with a transparent sheet, and using a magnetic pen to write characters or drawings.

Further, the present invention is the telephone wherein the direction of the microcapsule is initialized by the panel sweeping the panel surface using a band-shaped plastic magnet.

Further, according to the present invention, the panel uses an electric signal when the use of the telephone is terminated and the receiver is put on the telephone as a trigger signal as a signal for ending the telephone call, and after a predetermined time elapses, the panel uses the electric signal. Apply voltage to the electromagnet on the back of the panel,
This is a telephone in which the direction of the microcapsule is initialized by generating a magnetic field.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A telephone with a memo function according to an embodiment of the present invention will be described below.

FIG. 1 is a schematic view of a telephone with a memo function according to an embodiment of the present invention. In FIG. 2, FIG.
FIG. 1 is a cross-sectional view of a panel having a memo function in a telephone with a memo function.

The panel having a memo function shown in FIG. 2 is obtained by uniformly arranging desired microcapsules 21 on a panel plate 23 and covering the microcapsules 21 with a transparent sheet 22. The microcapsule 21 is formed of a transparent and fine plastic hollow sphere, in which a fine magnetic needle is sealed together with a transparent liquid medium.

When writing characters or figures, use a magnetic pen 3
Using 1, the direction of the magnetic needle in the microcapsule 21 is changed from a horizontal direction to a vertical direction to increase the transparency of the capsule. Thereby, the color of the background plate 32 of the capsule in the panel plate is exposed on the surface, and the contents in which characters or figures are entered appear.

In order to forcibly erase the contents of the written characters or figures, a magnetic field in another direction may be applied from another direction. The method 1 will be described below.

A magnetic material such as ferrite is mixed with a plastic material and magnetized to form a plastic magnet. This plastic magnet is easy to cut and easy to form into a thin strip.

As shown in FIG. 4, by sweeping the plastic magnet 41 on the surface of the panel 42, the magnetic needle in the capsule can be returned in the horizontal direction, and the written characters and the like are erased. . Further, as shown in FIG. 5, the plastic magnet 41 is arranged in the lateral direction of the panel, and can be similarly erased by a user's manual operation.

Next, the method 2 will be described below.

As shown in FIG. 6, a method may be employed in which an electromagnet 61 is provided on the back surface of the panel 41 and a magnetic field is generated by an electric signal to erase the magnetic field. This means that when the call is terminated and the user returns the handset to the predetermined position, an electric signal can be automatically generated and erased.

It is natural that the time from when the receiver is placed to when the electric signal is generated can be freely changed by an electric circuit. Thus, even if the user forgets to erase, the characters or figures on the panel are automatically erased, and the panel is always initialized when the next person uses it.

[0029]

As described above, according to the present invention, it is possible to improve the above disadvantages and to provide a telephone having a memo function provided with a memo panel integrated with the telephone.
