(B) Conventional technology and problems to be solved Utility model registration No. 1249577 (Jitsuko Sho 53-261)
0) The direct reading instrument for the blind forms an electric circuit by rotating the instrument cover and contacting the L-shaped electrical contact interlocking with the instrument cover with the electrical contact of the pointer indicating the current scale in a cross shape, The blind person sounds the buzzer connected to this and reads the scale through the visual scale by the pointer position indicating needle. In this case, since the contact of the electric contact is made by the cross contact between the L-shaped electric contact and the pointer contact, When the battery of the buzzer runs out, the buzzer stops sounding, and even if there is contact between the contacts, it is not known, so the instrument cover is further rotated, and the pointer contact that indicates the current scale is further As a result of the rotation, an excessive external force is generated in the mechanical portion inside the instrument, resulting in failure of the instrument, and there is a drawback that the purpose of measurement cannot be achieved. Further, if dust or the like adheres to the surface of the contact, or if oxidation or the like occurs, there is a problem that contact failure of the contact cannot be achieved and the purpose of measurement cannot be achieved. This proposal was made to solve these problems.

The conductive convex seat (4) is fixed to the see-through plate (3) so that it is centered, that is, concentric circles. The outer diameter of the round bar of the conductive ring (10) or the pipe must be smaller than the height (h) of the conductive convex seat (4). Next, with the lower end of the cylindrical reed switch (15) facing the center of the see-through plate (3), the lead wire (14
A conductive ring (1) for fixing the tip of -A) to the see-through plate (3)
It is inserted and penetrated into the slot (13) of (0). At this time, it is necessary to determine the size of the groove hole (13) in advance so that the lead wire (14-A) does not come into contact with the side surface portion inside the groove hole (13). Then, the lead wire (14-
The end portion of A) is inserted and contacted toward the center of the conductive convex seat (4), and the portion of the conductive convex seat (4) in contact with the circular seat portion is fixed with solder or the like. The upper end of one reed switch (15) is oriented in the same direction as the scale (23) line for indicating the rotation of the pointer (16), and the linear lead wire (14) protruding from this upper end is -B) is bent, folded back, and fixed on the outer peripheral surface of the conductive ring (10) with solder or the like at the contact portion. The components to be mounted on the scale plate (9) in the instrument case (1) described below are the components that are fixed to the surface of the see-through plate (3) by mounting the instrument cover (2) on the instrument case (1). The instrument cover (2) will be described as being attached to the instrument case (1) because it is configured as an electric contact device by contacting with or facing with.

In this case, when the reed switch (15) is rotated to face and face directly above the pointer, the magnetic force of the magnet (17) activates the contact of the reed switch (15), Turn on the magnet (1
7) shall be attached to the tip of the pointer (16). In this case, depending on the weight of the magnet (17), the pointer (16)
Since the weight increases first, it is necessary to remove the tilt error by attaching solder or the like to the tail of the pointer (16) to adjust the balance of the pointer (16). Next, the convex seat made of a strip-shaped elastic metal thin plate in which a hole into which the mounting screw (7) is inserted is opened at the end of the head of the convex seat strut (6) mounted on the scale plate (9).

At this time, the tip portion of the convex sitting conductor plate (5) is attached so that the tip portion of the convex sitting seat (4) fixed to the center of the see-through plate (3) is crimped and contacted. Similarly, a screw (7) is attached to the head of the ring column (12) mounted on the scale plate (9) and also to the end thereof.
It is assumed that the ring conductive plate (11) made of a strip-shaped elastic metal thin plate having a hole into which is inserted is attached and fixed by the attaching screw (7). At this time, the tip of the ring conductive plate (11) is attached so as to be in pressure contact with the curved upper surface of the circumference of the conductive ring (10) fixed to the surface of the see-through plate (3). At this time, the tip of the ring conductive plate (11) needs to be long enough not to contact the conductive convex seat (4).
Next, the instrument cover (2) is to be attached to the instrument case (1). This structure causes the turning groove (21) to be formed on the outer circumference of the instrument case (1), while the instrument cover (1) is formed. On the circumference of the outer side surface of (2), the machine screws (18) are attached from the three sides toward the center, and the machine screws (18) are attached.
Even if the leg ends of the instrument cover enter the turning groove (21) and the instrument cover (2) is pulled vertically upward, the instrument cover (2) does not separate from the instrument case (1), and the instrument cover ( When rotating 2) in the circumferential direction, machine screws (1
The tip of the leg of 8) floats in the turning groove and the instrument cover (2)
It is assumed that it can be rotated with respect to. Further, a pointer position indicating needle (19) is attached to the outer circumferential portion of the instrument cover (2), and this position is at the reed switch (1
Since 5) is made of glass and has a cylindrical shape, it serves as a needle placement needle (16), and the conductive convex seat (4).

(D) Action, embodiment In FIG. 1, FIG. 2 and FIG. 3, the action of the present invention, and
An embodiment as a thermometer will be described. Now, it is assumed that the pointer (16) of this thermometer indicates the scale of 40 ° C. When a blind person measures this, a cord (22) is connected to a buzzer with a battery, and the tip of the index finger of the right hand is connected to the pointer position indicating needle (1
9) and at the same time apply the tip of the finger to a convex finger scale (2
0) lightly touching it, while the thumb of the right hand touches the outer circumferential corner of the instrument cover (2) and the index finger and thumb are shaped so as to grab the instrument cover (2). In this state, as shown in FIG. 3, when the instrument cover (2) is gently rotated in the direction of the arrow, the reed switch (3) fixed to the surface of the see-through plate (3) is rotated by the rotation of the instrument cover (2). 15) also interlocks, and when it comes directly above the pointer (16), the magnetic force of the magnet (17) at the tip of the pointer (16) acts on the reed switch (15) to turn it on, and the reed switch (15) sets the needle. It plays an important role and forms an electric circuit. That is, the cord (22) → mounting screw (7) →
Ring support (12) → ring conductive plate (11) → conductive ring (10) → lead wire (14-B) → reed switch (15) → lead wire (14-A) → conductive convex seat (4) → convex Seat conductive plate (5) → Convex seat support (6) → Mounting screw (7)
→ Code (22) → An electric circuit such as a buzzer with a battery is formed to give an alarm. Therefore, since the position of the reed switch (15) indicates the position of the pointer (16), the tactile sensation of the tip of the forefinger is measured while tactile sensation is maintained, even when the finger scale (20) is being rotated. Since the continuation is continued, at the time when the buzzer sounds, the scale at that position can be immediately tactilely read by the pointer position indicating needle (19). In the drawing, a turning groove (21) is provided on the outer peripheral surface of the instrument case (1), and the tip of a small screw (18) attached to the instrument cover (2) is inserted into the groove to remove the instrument cover (2). Although the instrument cover (2) is configured to rotate, the instrument cover (2) may be rotated by making a male screw on the instrument case (1) and a female screw on the instrument cover (2). In this case, when the instrument cover (2) is rotated, the pitch of the screw for only one rotation causes a gap variation between the reed switch (15) and the magnet (17). Or, it is necessary to use a magnet having a slightly stronger magnetic force. In addition, the convex sitting conductor (5) and the ring conducting plate (11) are directly attached to the circumferential side surface of the instrument case (1) without using the convex sitting strut (6) and the ring strut (12). Attach with screws (7), instrument case (1)
The same effect can be obtained by connecting the cord (22) to the outside. Also, in the drawing, outside the ring of the conductive ring (10),
The reed switch (15) was installed, but the conductive ring (1
The diameter of 0) may be increased and the reed switch (15) may be installed in the conductive ring (10). In this case, the lead wire (14-B) protruding from the upper end of the reed switch (15) is not bent, but remains straight, and the contact point on the inner circumference of the conductive ring (10) is It may be fixed with solder or the like.

(E) Effect of the device Since the reed switch is actuated by the magnetic force of the magnet without contact, it is possible to prevent the blind person from accidentally moving the pointer currently instructed during operation, which causes various harmful effects. It is possible to eliminate the trouble of the instrument, and to turn on the contact of the reed switch. OF
Since F is performed in the glass tube, there is no failure such that dust or the like adheres to the contact part and the buzzer does not sound, and
Contact ON. Since it is turned off with a magnet,
The buzzer sounds clearly and has the effect of being usable as a reliable instrument for the blind. Also, since the reed switch that functions as a placement needle can be freely set to the upper or lower limit temperature position from the pointer, it is ideal for blind people,
It is effective as a disaster prevention instrument that can be used by blind people for indoor temperature control or fire temperature warning. The present invention has an effect that it can be used for a blind person of a dial type instrument as an electric device type such as a thermometer, a barometer, and a pressure gauge, or for general use.
