There is no problem as long as it is a fixed device or device that uses a commercial power supply such as 100 V as a power source. It will be significantly shortened. For this reason, in a device or an apparatus using a battery as a power supply, a Braille display device using a shape memory alloy as a driving member cannot be adopted. In addition, even if the configuration does not use a shape memory alloy, it cannot be applied to the case where the magnet or the like needs to be constantly energized during the Braille display, because the power consumption is also large. .

In the present invention, in both the braille display state and the non-braille display state, the energization of the coil 112 is performed only momentarily at a predetermined time. Therefore, power consumption becomes extremely small because continuous energization is not performed as in the related art. In a Braille display state (a state in which the Braille protrusion 101 protrudes from the surface of the housing 102), the Braille protrusion 101 protrudes from the surface of the housing 102, as shown in FIG. At this time, the locking member 10 is provided in the concave portion 105a of the permanent magnet 105.

6 is excited, and the generated magnetic force is applied to the permanent magnet 105 along with the path of the iron core 106 and the induction core 107. At this time, the lower end of the core 106 is the N pole, the lower end of the induction core 107 is the S pole,
The upper end of “a” is the N pole, and the permanent magnet 110 remains the original magnetic pole. As a result, the permanent magnet 110 and the N pole of the vertical portion 107a attract each other, the permanent magnet 110 is drawn to the right side in the drawing, the locking member 109 moves to the right along with the permanent magnet 110, and the tip end thereof is moved to the permanent magnet. 105 recess 105
It escapes from a and enters an unlocked state. Then, the permanent magnet 105 is pushed down by the urging force of the coil spring 104, and at the same time, the N pole of the permanent magnet 105 is drawn because the upper end of the iron core 106 is the S pole.
The lower end surface of the magnet 05 and the upper end surface of the iron core 106 come into close contact with each other, and the permanent magnet 105 stops. This state is shown in FIG.
It is. The magnetic force of the permanent magnet 105 on the iron core 106 is
Since it is larger than the urging force of the coil spring 104, the attracted state between the permanent magnet 105 and the iron core 106 is maintained. Therefore, after the point in time when the permanent magnet 105 and the iron core 106 are brought into close contact with each other, the state of FIG.

態を示したのが図２の（ｂ）である。Next, the state of FIG. 2A (FIG. 1B)
When the coil 112 is energized such that a repulsive force is generated on the permanent magnet 105, that is, an S pole is generated at the upper end of the iron core 106, the N pole at the lower end of the permanent magnet 105 is changed. And a repulsive force is generated. At this time, since an S pole is generated at the lower end of the induction core 107, an N pole is formed at the upper end of the vertical portion 107 a of the induction core 107, and a repulsive force is generated between the induction magnet 107 and the permanent magnet 110. Therefore, the permanent magnet 105 is pushed up against the coil spring 104, and at the same time, the permanent magnet 110 is pushed out to the left side in the drawing, and the tip of the locking member 109 is in contact with the turning surface of the permanent magnet 105. In the process of pushing up the permanent magnet 105, the recess 105a of the permanent magnet 105 moves upward, and when facing the tip of the locking member 109, the tip of the locking member 109 fits into the recess 105a. At this point, the permanent magnet 10
5 stops and its state is maintained. In addition, locking member 1
09 is urged by the coil spring 111 to the left in the figure, so that its tip remains fitted in the recess 105a. At this time, the upper end of the Braille projection 101 is
02 protrudes from the surface of No. 02 and becomes a state of Braille display. FIG. 2B shows this state.

低価格化を図ることが可能になる。As described above, since the coil 112 is only energized temporarily, a low power consumption Braille display device can be obtained without imposing a load on the power supply.
Therefore, even if the device (apparatus) to which the braille display device is applied is a mobile phone, a PHS, a portable information terminal device, or the like using a battery as a power supply, no inconvenience occurs. Moreover, because the structure is simple, it does not take up installation space,
It is possible to reduce the price.

Is provided, and even in the configuration in which the Braille projections 101 are provided, power consumption is achieved by sequentially energizing the plurality of coils 112 by a control circuit including a combination of a microcomputer, a ROM, and a drive circuit. And a Braille display device with a small number of components can be constructed.
In this case, needless to say, only one power source is required.
