Abstract

PROBLEM TO BE SOLVED: To provide a position indicator having contact points with higher durability achieved through reduction of stress acting on a connection site between a terminal part and a metal fitting member connected to the terminal part.SOLUTION: A first coupling portion 86 and second coupling portion 87 are coupled with a second tabular portion 82 and third tabular portion 83, respectively, at positions away from a planar portion 90 of a first metal fitting surface 91 in a front-back direction. This allows a second metal fitting surface 92 and third metal fitting surface 93 to have gaps D1, D2 between themselves and a front surface 52 and rear surface 53 of a metal fitting fixing part 44, respectively. Thus, when the first metal fitting surface 91 is brought into contact with a front-end surface 51, interference with the metal fitting fixing part 44 is avoided even if the second tabular portion 82 and third tabular portion 83 are not orthogonal to a first tabular portion 81. This allows for reliably fixing a terminal metal fitting 80 to the metal fitting fixing part 44 with the first metal fitting surface 91 in contact with the front-end surface 51, and minimizing stress exerted on a wax material 49.

Description

  The present invention relates to a position indicator that indicates a position to a position detection device.

  2. Description of the Related Art Conventionally, a position indicator that indicates a position is provided to a position detecting device that includes a position indicating means in a housing and includes a position detecting means that detects the position of the position indicating means by interaction with the position indicating means. Are known. For example, an electronic pen that uses electromagnetic induction to indicate a position with respect to a position detection device includes a coil and an electronic circuit that generates a magnetic field from the coil in a housing. The position detection device includes a sensor substrate in which a plurality of antenna coils arranged in two axial directions orthogonal to each other are stretched on a sensor surface. The position detection device sequentially switches the antenna coil switches, passes a current sequentially through the individual antenna coils, and scans the sensor surface in each of the two axial directions. The position detection device detects a signal based on a change generated in the current flowing through the antenna coil by electromagnetic induction, and calculates the position of the electronic pen with respect to the sensor substrate.

  By the way, there is provided a position detection device capable of acquiring position coordinate data corresponding to the written content written on a medium such as paper arranged on the position detection device by an electronic pen having a coil and an electronic circuit incorporated in the writing instrument. It is known (see, for example, Patent Document 1). The electronic pen described in Patent Document 1 includes a switch that operates in accordance with the contact state of the pen tip with the writing surface during writing. When the pen tip is pressed against the writing surface during writing, the switch closes and the contact is turned on. When the pen tip is separated from the writing surface, the switch opens and the contact is opened.

  However, since the electronic pen of Patent Document 1 has a structure in which the pen tip and the switch are arranged side by side in the axial direction of the electronic pen, a load applied to the pen tip at the time of writing is applied to the contact of the switch, and the degree of on / off of the switch There is a possibility of contact wear. If the contact is reinforced with metal fittings to increase the durability of the contact, the metal fitting is pressed against the contact each time the switch is turned on and off, so stress is applied to the connection part that electrically connects the metal fitting to the contact, causing breakage There was a possibility.

  An object of this invention is to provide the position indicator which can reduce the stress added to the connection part of a terminal part and the metal fitting member connected to a terminal part, and can improve durability of a contact.

  According to one aspect of the present invention, the position indicating the position to the position detecting device including the position detecting means for detecting the position of the position indicating means by interaction with the position indicating means incorporated in the housing. An indicator that extends between one end and the other end and transmits an external force applied to the one end directly or indirectly from the outside of the housing to the other end; and the direction of the surface A first terminal surface disposed toward the other end portion of the transmission member, a second terminal surface connected perpendicularly to the first terminal surface, and a second terminal surface are provided, and the position indicating means is energized. A terminal member having a pair of terminal portions that are electrically connected to the energization circuit that is electrically connected to each of the pair of terminal portions held by the terminal member. A pair of metal fitting members that are electrically conductive, A conductive member that is provided at the other end and contacts each of the pair of metal fitting members when the transmission member transmits an external force to bring the metal fitting members into a conductive state; and the first terminal of the terminal member An elastic member that biases the surface and the conducting member away from each other and maintains the non-conducting state between the metal fittings when the transmission member does not transmit an external force, Facing the first terminal surface of the terminal member and facing the second terminal surface of the terminal member, a first plate-like portion having a first metal fitting surface arranged in close contact with the first terminal surface; And a second plate-like portion having a second metal fitting surface arranged with a gap between the second terminal surface and the first plate-like portion and the second plate-like portion. And at least a part of the second plate-like part by brazing. Position indicator, characterized in that fixed to the serial terminal portion is provided.

  In this aspect, when the metal fitting member is assembled to the terminal member, the second plate-like portion is brazed to the terminal portion. At this time, the 1st metal fitting surface of a 1st plate-shaped part is the state closely_contact | adhered to the 1st terminal surface of the terminal member. On the other hand, the second metal fitting surface of the second plate-like portion is in a state having a gap with the second terminal surface. The first metal fitting surface of the first plate-like portion of the metal fitting member and the second metal fitting surface of the second plate-like portion are not necessarily orthogonal to each other. For this reason, when assembling the metal fitting member to the terminal member, if the first metal fitting surface of the first plate-like part is brought into close contact with the first terminal surface of the terminal member, the second plate-like part is the second terminal of the terminal member. May interfere with the surface. However, this aspect allows a gap to be provided between the second plate-like portion and the terminal member, so that when the metal fitting member is assembled to the terminal member, the second plate-like portion and the terminal member second Interference with the terminal surface can be avoided. Therefore, it can arrange | position in the state which contact | adhered the 1st metal fitting surface to the 1st terminal surface. Then, the second plate-like portion is brazed to the terminal portion with a brazing material, and the metal fitting member is fixed to the terminal member, so that the first metal fitting surface of the first plate-like portion becomes the first terminal surface of the terminal portion. It can be kept in close contact.

  Further, in the use of the position indicator, when the transmission member transmits an external force and the conductive member contacts the metal fitting member, the first plate-shaped portion of the metal fitting member is moved from the conductive member to the first terminal surface side of the terminal member. It is pressed toward. When the first metal fitting surface of the first plate-like portion has a gap between the first terminal surface of the terminal portion, the stress received by the metal fitting member is applied to the brazing material via the first connecting portion and the second plate-like portion. It is transmitted and stress is applied to the brazing material. In this aspect, as described above, the first metal fitting surface of the first plate-shaped portion is in close contact with the first terminal surface of the terminal portion. For this reason, the pressing force received by the metal fitting member via the conductive member is directly transmitted to the terminal member side, and the stress transmitted to the brazing material via the second plate-like portion is reduced. Therefore, since stress is not easily applied to the second plate-shaped portion, the brazing material can be prevented from being damaged or peeled off. Therefore, this aspect can prevent the metal member from falling off from the terminal member, and can improve the durability of the contact.

  In this aspect, the terminal member may include a third terminal surface connected to the first terminal surface orthogonal to the first terminal surface on a surface opposite to the second terminal surface.

The first plate-like portion is a flat portion including the first metal fitting surface, orthogonal to the ridge line direction between the first terminal surface and the second terminal surface, and in the first direction along the first terminal surface. You may have a plane part whose length is more than the length of the said 1st terminal surface of the said terminal member.

  In this aspect, since the flat portion including the first metal fitting surface is secured in the first plate-like portion, the first terminal surface is an end portion on the R surface that can be generated on the inner surface side of the first connection portion or the second connection portion. It can be made to adhere to a 1st metal fitting surface reliably, without applying. Furthermore, similarly to the second plate-like portion, the third plate-like portion can have a gap between the third metal fitting surface and the third terminal surface of the terminal member. Therefore, when assembling the bracket member to the terminal member, avoid the interference between the second plate portion and the second terminal surface and the interference between the third plate portion and the third terminal surface, respectively, The first metal fitting surface of the part can be arranged in a state of being in close contact with the first terminal surface of the terminal member. Therefore, it is possible to suppress the brazing material from being damaged or peeled off when the stress applied to the metal fitting member is transmitted when the conductive member contacts the metal fitting member, and to prevent the metal fitting member from falling off from the terminal member. Can increase the durability.

A fifth plate-like portion having a fifth metal fitting surface disposed at a position facing the second terminal surface of the terminal member and having a gap between the second terminal surface; You may have a 4th connection part which connects a plate-shaped part and the said 5th plate-shaped part. In this case, the part closest to the fifth plate-like part among the parts of the second plate-like part and the part closest to the second plate-like part among the parts of the fifth plate-like part are brazed. May be fixed to the terminal portion.

  In this aspect, since the metal fitting member is an open ring shape, it can be fitted into the terminal member so as to go around the terminal member when attached to the terminal member, and can be prevented from dropping during assembly. In addition, the bracket member is between the second bracket surface and the second terminal surface, between the third bracket surface and the third terminal surface, between the fourth bracket surface and the fourth terminal surface, and the fifth bracket surface. There may be a gap between the first terminal surface and the second terminal surface. Therefore, the first metal fitting surface of the first plate-like portion can be easily brought into close contact with the first terminal surface of the terminal member without forcibly bending the metal fitting member. In this state, the metal plate member is firmly fixed to the terminal member by brazing the second plate-like portion and the fifth plate-like portion to the terminal portion, and the first metal fitting surface is in close contact with the first terminal surface.

Therefore, it is possible to suppress the brazing material from being damaged or peeled off when the stress applied to the metal fitting member is transmitted when the conductive member contacts the metal fitting member, and to prevent the metal fitting member from falling off from the terminal member. Can increase the durability.

  In this aspect, the metal fitting member may have a fourth connecting portion that connects the fourth plate-like portion and the second plate-like portion, and may be formed in an annular shape. In this aspect, since the metal fitting member can be fitted around the terminal member once around the terminal member when attached to the terminal member, it can be prevented from dropping during assembly. The metal fitting member has gaps between the second metal fitting surface and the second terminal surface, between the third metal fitting surface and the third terminal surface, and between the fourth metal fitting surface and the fourth terminal surface. be able to. Therefore, the first metal fitting surface of the first plate-like portion can be easily brought into close contact with the first terminal surface of the terminal member without forcibly bending the metal fitting member. In this state, by brazing the second plate-like portion to the terminal portion, the metal fitting member can be firmly fixed to the terminal member, and the state where the first metal fitting surface is in close contact with the first terminal surface can be maintained. Therefore, it is possible to suppress the brazing material from being damaged or peeled off when the stress applied to the metal fitting member is transmitted when the conductive member contacts the metal fitting member, and to prevent the metal fitting member from falling off from the terminal member. Can increase the durability.

In this aspect, the terminal member may be a circuit board on which the energization circuit is mounted. In this aspect, since it is not necessary to prepare a terminal member separately from the substrate on which the energization circuit is mounted, the number of parts can be reduced. Therefore, the weight of the position indicator can be reduced.

Similarly to the above, the second spring 65 is a coiled compression spring made of, for example, SUS. The base end of the second spring 65 abuts on the flange 72 of the spring holder 70. The distal end of the second spring 65 abuts on the base end surface of the refill holder 30. The second spring 65 presses the refill holder 30 toward the tip end side in the axial direction against the spring holder 70. The base end surface of the refill holder 30 is maintained in a state separated from the distal end portion of the spring holder 70 by the second spring 65. The second spring 65 reduces the load applied to the substrate 40 by compressing the second spring 65 when the first spring 60 is compressed and further receiving a pressing force in a state where the terminal fitting 80 of the substrate 40 and the spring holder 70 are in contact with each other. To do.

  Although not shown, a known ratchet mechanism (not shown) for moving the frame 20 in the axial direction of the cover body 10 by pressing the knock portion 17 is provided inside the cover body 10. The ratchet mechanism repeats a series of movements of sliding, fixing, and releasing the frame 20 by a mechanism that uses a force and a spring to push the knock portion 17. When the knock portion 17 is pressed once, the ratchet mechanism fixes the frame 20 in a state in which the frame 20 is slid to the front end side of the cover body 10 and causes the pen tip 16 of the refill 15 to protrude from the opening portion 14 of the cover body 10. When the knock portion 17 is pushed again, the ratchet mechanism releases the fixation, slides the frame 20 and moves it to the proximal end side of the cover body 10, and moves the pen tip 16 from the opening portion 14 of the cover body 10 into the cover body 10.

  With reference to FIGS. 3-5, the switch which the metal fixture fixing | fixed part 44 of the board | substrate 40, the spring holder 70, and the 1st spring 60 comprise is demonstrated. As described above, the metal fitting fixing part 44 is formed at the tip of the substrate 40 and is a part where the pair of terminal metal fittings 80 are assembled. By forming groove-shaped notches 42 on both end surfaces of the substrate 40 in the left-right direction, the metal fixture fixing portion 44 has a form in which the left and right end portions protrude in the left-right direction from the center. Further, by forming the notch portion 42, the end portions of the metal fixture fixing portion 44 have base end surfaces 54 in which the orientation of the surface faces the base end side, respectively.

  The terminal metal fitting 80 is a metal fitting formed by bending a narrow plate material made of SUS or the like, for example, by press working into a rectangular open ring.

Concatenate with The third metal fitting surface 93 facing the inside of the terminal fitting 80 in the third plate-like portion 83 faces the rear surface 53 of the fitting fixing portion 44 when the terminal fitting 80 is assembled to the fitting fixing portion 44. The fourth plate-like portion 84 is connected to the third plate-like portion 83 on the rear side in the front-rear direction via the third connecting portion 88 and is connected to the fifth plate-like portion 85 via the fourth connecting portion 89 on the front side. To do. The fourth metal surface 94 facing the inside of the terminal metal fitting 80 in the fourth plate-like portion 84 faces the base end surface 54 of the metal fitting fixing portion 44 when the terminal metal fitting 80 is assembled to the metal fitting fixing portion 44. The fifth plate-like portion 85 is connected to the fourth plate-like portion 84 at the proximal end side in the axial direction via the fourth connecting portion 89, and the distal end side constitutes the second end portion 97 of the open annular terminal fitting 80. . The second end portion 97 is disposed in the vicinity of the center in the axial direction on the front surface 52 of the metal fitting fixing portion 44 and is separated from the first end portion 96 in the axial direction. The fifth metal surface 95 facing the inside of the terminal fitting 80 in the fifth plate-like portion 85 faces the front surface 52 of the metal fitting fixing portion 44 when the terminal metal fitting 80 is assembled to the metal fitting fixing portion 44.

  The first metal fitting surface 91 has a plane portion 90 in which the length L1 in the front-rear direction is equal to or longer than the length L2 in the front-rear direction of the metal fixture fixing portion 44 (that is, the thickness of the substrate 40). That is, when the terminal fitting 80 is assembled to the fitting fixing portion 44, the front and rear ends of the tip end face 51 of the fitting fixing portion 44 are not applied to the first connecting portion 86 and the second connecting portion 87. 51 can be arranged in the plane part 90. The first connecting portion 86 is connected to the second plate-like portion 82 at a position farther to the front side in the front-rear direction than the flat portion 90. Similarly, the second connecting portion 87 is connected to the third plate-like portion 83 at a position farther rearward than the plane portion 90 in the front-rear direction. Therefore, when the terminal fitting 80 is assembled to the fitting fixing portion 44, the first fitting surface 91 can be in close contact with the distal end surface 51 of the fitting fixing portion 44. In this state, the second metal fitting surface 92 can have a gap D <b> 1 between the front surface 52 of the metal fitting fixing portion 44. Similarly, the third metal fitting surface 93 can have a gap D <b> 2 between it and the rear surface 53 of the metal fitting fixing portion 44.

  Axial direction between the position on the inner surface side at the position where the second connecting portion 87 is connected to the first plate-like portion 81 and the position on the inner surface side at the position where the third connecting portion 88 is connected to the fourth plate-like portion 84. This length L3 is longer than the axial length L4 of the rear surface 53 of the metal fixture 44. Therefore, when the terminal fitting 80 is assembled to the fitting fixing portion 44 with the first fitting surface 91 and the distal end surface 51 being in close contact with each other, the fourth fitting surface 94 is between the proximal end surface 54 of the fitting fixing portion 44. Can have a gap D3. Axial direction between the position on the inner surface side at the position where the third connecting portion 88 is connected to the third plate-like portion 83 and the position on the inner surface side at the position where the fourth connecting portion 89 is connected to the fifth plate-like portion 85. The length L5 is longer than the length L6 in the front-rear direction of the base end face 54 of the metal fixture 44. Therefore, when the terminal metal fitting 80 is assembled to the metal fitting fixing portion 44 with the first metal fitting surface 91 and the front end surface 51 being in close contact, the fifth metal fitting surface 95 is between the front surface 52 of the metal fitting fixing portion 44. There may be a gap D4.

  When the first metal fitting surface 91 and the front end surface 51 of the metal fitting fixing portion 44 are brought into close contact with each other when the terminal metal fitting 80 having such a configuration is assembled to the metal fitting fixing portion 44, the front surface 52 and the rear surface of the metal fitting fixing portion 44 are arranged. The gaps D <b> 1 to D <b> 4 can be provided between the base 53 and the base end surface 54. Due to manufacturing tolerances at the time of manufacture, the terminal fitting 80 is, for example, in a direction in which the second connecting portion 87 connects the third plate-like portion 83 with respect to a direction orthogonal to the direction in which the first plate-like portion 81 extends. Deviation may occur. For example, when the angle formed by the surface direction of the first metal fitting surface 91 and the surface direction of the third metal fitting surface 93 is an acute angle, if the first metal fitting surface 91 and the tip surface 51 are to be brought into close contact with each other, There is a possibility that the surface 93 comes into contact with the rear surface 53 on the base end side and cannot be brought into close contact. However, since the terminal fitting 80 is configured to have a gap D2 between the third fitting face 93 and the rear face 53 when the first fitting face 91 and the front end face 51 are brought into close contact with each other, Interference with the rear surface 53 can be avoided. Similarly, the terminal fitting 80 has a gap D1 and a gap D4 between the second fitting surface 92 and the fifth fitting surface 95 and the front surface 52, respectively, and a gap between the fourth fitting surface 94 and the base end surface 54. Because of the configuration having D3, interference between the surfaces can be avoided. Therefore, the terminal metal fitting 80 can securely bring the first metal fitting surface 91 and the tip end face 51 of the metal fitting fixing portion 44 into close contact with each other when assembled to the metal fitting fixing portion 44.

  The terminal fitting 80 has the first end portion 96 and the fifth plate-like portion 85 of the second plate-like portion 82 in a state where the first fitting surface 91 and the tip end surface 51 are in close contact with each other in the assembling process to the fitting fixing portion 44. The second end portion 97 is brazed to the electrode pads 47 and 48 and fixed to the metal fixture fixing portion 44. After the fixing, the state where the first metal fitting surface 91 and the front end surface 51 are in close contact with each other is maintained.

  As described above, the collar portion 72 of the spring holder 70 is maintained in a state of being separated from the front end surface 51 of the substrate 40 by the pressing force of the first spring 60. When writing, when the pen tip 16 is pressed against the writing surface, an external force received as a drag force from the writing surface is transmitted to the spring holder 70 via the refill 15 and the refill holder 30, and the spring holder 70 moves to the proximal end side. . The spring holder 70 compresses the first spring 60, brings the flange 72 close to the front end surface 51 of the substrate 40, and makes the flange 72 abut against the pair of terminal fittings 80 of the fitting fixing portion 44. An external force is applied to the terminal fitting 80 in the axial direction from the spring holder 70.

  As described above, the terminal fitting 80 has the first end portion 96 of the second plate-like portion 82 and the fifth plate-like portion 85 in a state where the first fitting surface 91 is in contact with the distal end surface 51 of the fitting fixing portion 44. The second end portion 97 is soldered to the electrode pads 47 and 48 and is fixed to the metal fixture fixing portion 44 by a brazing material 49. Therefore, even if an external force is applied from the spring holder 70, the first plate-like portion 81 of the terminal fitting 80 is regulated by the distal end surface 51 that contacts the first fitting surface 91 and does not move in the axial direction to the proximal end side. Therefore, the second plate-like portion 82 connected to the first plate-like portion 81 via the first connecting portion 86 does not move in the axial direction, and the brazing material 49 joined to the first end portion 96 is not subjected to stress. Damage or peeling is suppressed. Also, the fifth plate-like portion 85 connected to the first plate-like portion 81 via the third plate-like portion 83 and the fourth plate-like portion 84 does not move in the axial direction, and the second end portion 97 The brazing material 49 to be joined is not subjected to stress, and breakage and peeling are suppressed.

  The pair of terminal fittings 80 are conducted through the spring holder 70, the energization circuit is turned on, and a current flows from the energization circuit to the coil 75. The sensor boards 9L and 9R of the position detection device 1 detect a signal based on a change generated in the current flowing through the antenna coil by electromagnetic induction caused by the magnetic field generated in the coil 75, obtain the position of the electronic pen 3 by calculation, and output it. To do. When the nib 16 is away from the writing surface, the external force transmitted to the spring holder 70 disappears, the first spring 60 expands, and the collar portion 72 is moved away from the front end surface 51 of the substrate 40, so A pair of terminal metal fitting 80 and the collar part 72 will be in a non-contact state. The pair of terminal fittings 80 are in a non-conductive state, the energization circuit is turned off, and energization to the coil 75 from the energization circuit is stopped. The electromagnetic induction for the sensor substrates 9L and 9R of the position detection device 1 is stopped.

  As described above, in the present embodiment, when the terminal fitting 80 is assembled to the fitting fixing portion 44 of the substrate 40, the second plate-like portion 82 has the first end portion 96 brazed to the electrode pads 47 and 48. The At this time, the first metal fitting surface 91 of the first plate-like portion 81 is in close contact with the distal end surface 51 of the metal fitting fixing portion 44. On the other hand, the second metal fitting surface 92 of the second plate-like portion 82 is in a state having a gap D <b> 1 with the front surface 52 of the metal fitting fixing portion 44. The first metal fitting surface 91 of the first plate-like portion 81 of the terminal fitting 80 and the second metal fitting surface 92 of the second plate-like portion 82 are not necessarily orthogonal to each other. Therefore, when the terminal fitting 80 is assembled to the fitting fixing portion 44, if the first fitting surface 91 of the first plate-like portion 81 is brought into close contact with the distal end surface 51 of the fitting fixing portion 44, the second plate-like portion 82. May interfere with the front surface 52 of the metal fixture 44. However, in the present embodiment, when the terminal fitting 80 is assembled to the metal fixture fixing portion 44 by allowing the gap D1 to be provided between the second plate-like portion 82 and the metal fixture fixing portion 44, the second plate Interference between the shape portion 82 and the front surface 52 of the metal fixture portion 44 can be avoided. Therefore, the first metal fitting surface 91 can be disposed in a state of being in close contact with the front end surface 51. Then, the second plate-like portion 82 is soldered to the electrode pads 47, 48 with the brazing material 49, and the terminal fitting 80 is fixed to the fitting fixing portion 44, so that the first fitting surface of the first plate-like portion 81 is fixed. 91 can be maintained in close contact with the tip surfaces 51 of the electrode pads 47 and 48.

  Further, when the electronic pen 3 is used, when the refill holder 30 transmits external force through the refill 15 and the spring holder 70 contacts the terminal fitting 80, the first plate-like portion 81 of the terminal fitting 80 is separated from the spring holder 70. It is pressed toward the front end surface 51 side of the metal fitting fixing portion 44. When the first metal fitting surface 91 of the first plate-like portion 81 has a gap between the tip surfaces 51 of the electrode pads 47 and 48, the stress received by the terminal fitting 80 is the first connecting portion 86 and the second plate-like portion. It is transmitted to the brazing material 49 through 82, and stress is applied to the brazing material 49. In the present embodiment, as described above, the first metal fitting surface 91 of the first plate-like portion 81 is in close contact with the tip surfaces 51 of the electrode pads 47 and 48. For this reason, the pressing force received by the terminal fitting 80 via the spring holder 70 is directly transmitted to the fitting fixing portion 44 side, and the stress transmitted to the brazing material 49 via the second plate-like portion 82 is reduced. Therefore, since stress is not easily applied to the second plate-like portion 82, damage or peeling of the brazing material 49 can be suppressed. Therefore, according to this aspect, the terminal fitting 80 can be prevented from dropping from the fitting fixing portion 44, and the durability of the contact can be improved.

  Further, in the present embodiment, since the flat portion 90 including the first metal fitting surface 91 is secured in the first plate-like portion 81, the front end surface 51 is on the inner surface side of the first connecting portion 86 and the second connecting portion 87. An end portion is not applied to the R surface that may be generated, and the first metal surface 91 can be securely adhered. Further, similarly to the second plate-like portion 82, the third plate-like portion 83 can have a gap D <b> 2 between the third metal fitting surface 93 and the rear surface 53 of the metal fitting fixing portion 44. Therefore, when the terminal fitting 80 is assembled to the fitting fixing portion 44, the interference between the second plate-like portion 82 and the front surface 52 and the interference between the third plate-like portion 83 and the rear surface 53 are avoided, respectively. The first metal fitting surface 91 of the portion 81 can be disposed in a state of being in close contact with the tip surface 51 of the metal fitting fixing portion 44. Therefore, damage and peeling of the brazing material 49 that may occur when the stress received by the terminal fitting 80 is transmitted when the spring holder 70 contacts the terminal fitting 80 are suppressed. Dropping can be prevented and the durability of the contact can be improved.

Further, in the present embodiment, in a state where the first metal fitting surface 91 of the first plate-like portion 81 is disposed in close contact with the distal end surface 51 of the metal fitting fixing portion 44, the second metal fitting surface 92, the third metal fitting surface 93, and the first metal fitting surface 91 are arranged. Gaps D1, D2, and D3 can be provided between the four metal fitting surfaces 94 and the metal fitting fixing portions 44, respectively.
Therefore, when the terminal fitting 80 is assembled to the fitting fixing portion 44, the interference between the second plate-like portion 82 and the front surface 52, the interference between the third plate-like portion 83 and the rear surface 53, and the fourth plate-like portion 84 Interference with the base end face 54 can be avoided. Therefore, the first metal fitting surface 91 of the first plate-like portion 81 can be arranged in a state of being in close contact with the distal end surface 51 of the metal fitting fixing portion 44. Therefore, damage and peeling of the brazing material 49 that may occur when the stress received by the terminal fitting 80 is transmitted when the spring holder 70 contacts the terminal fitting 80 are suppressed. Dropping can be prevented and the durability of the contact can be improved.

  Further, in the present embodiment, since the terminal fitting 80 is an open ring shape, it can be fitted into the fitting fixing portion 44 so as to go around the fitting fixing portion 44 when being attached to the fitting fixing portion 44, and can be dropped during assembly. Can be prevented. Further, the terminal fitting 80 includes a second fitting surface 92 and a front surface 52, a third fitting surface 93 and a rear surface 53, a fourth fitting surface 94 and a base end surface 54, and a fifth fitting surface 95. And the front surface 52 may have gaps D1, D2, D3, and D4, respectively. Therefore, the first metal fitting surface 91 of the first plate-like portion 81 can be easily brought into close contact with the distal end surface 51 of the metal fitting fixing portion 44 without forcibly bending the terminal metal fitting 80. In this state, the terminal end 80 is brazed to the electrode pads 47, 48 by brazing the first end 96 of the second plate 82 and the second end 97 of the fifth plate 85 to fix the terminal fitting 80 to the fixture fixing portion 44. The first metal fitting surface 91 can be maintained in close contact with the distal end surface 51. Therefore, damage and peeling of the brazing material 49 that may occur when the stress received by the terminal fitting 80 is transmitted when the spring holder 70 contacts the terminal fitting 80 are suppressed. Dropping can be prevented and the durability of the contact can be improved.

  In the present embodiment, since the metal fixture fixing portion 44 is formed at the tip of the substrate 40, it is not necessary to prepare the substrate on which the energization circuit is mounted and the metal fixture fixing portion 44 separately, thereby reducing the number of components. Can do. Therefore, the weight of the electronic pen 3 can be reduced.

  In addition, this invention is not limited to the said embodiment, The change in the range which does not change the summary of invention is possible. The terminal fitting 80 has an opening in which the first end 96 of the second plate-like portion 82 arranged on the front surface 52 side of the fitting fixing portion 44 and the second end 97 of the fifth plate-like portion 85 are arranged apart from each other. Make a ring. For example, there is no fifth plate-like portion 85, and the front end portion of the fourth plate-like portion 84 and the base end side end portion of the second plate-like portion 82 are connected by the fourth connecting portion 89. By connecting, the terminal fitting 80 may form a closed ring. In this case, if the width of the central portion in the axial direction of the second plate-like portion 82 is narrowed and the second plate-like portion 82 is securely fixed to the electrode pads 47, 48 by soldering with the brazing material 49. Good.

  In this way, when the terminal fitting 80 is formed in a closed ring shape, the terminal fitting 80 can go around the fitting fixing portion 44 and fit into the fitting fixing portion 44 when attached to the fitting fixing portion 44. Can prevent falling. Similarly to the present embodiment, the terminal fitting 80 is formed between the second fitting surface 92 and the front surface 52, between the third fitting surface 93 and the rear surface 53, and between the fourth fitting surface 94 and the base end surface 54. Each can have a gap in between. Therefore, the first metal fitting surface 91 of the first plate-like portion 81 can be easily brought into close contact with the distal end surface 51 of the metal fitting fixing portion 44 without forcibly bending the terminal metal fitting 80. In this state, the second metal plate 82 is brazed to the electrode pads 47, 48 to firmly fix the terminal metal fitting 80 to the metal fitting fixing portion 44, and the first metal fitting surface 91 is in close contact with the tip surface 51. Can be maintained. Therefore, damage and peeling of the brazing material 49 that may occur when the stress received by the terminal fitting 80 is transmitted when the spring holder 70 contacts the terminal fitting 80 are suppressed. Dropping can be prevented and the durability of the contact can be improved.

  In addition, the terminal fitting 80 has the first end 96 of the second plate-like portion 82 connected to the electrode pad 47 in a state where the first fitting surface 91 of the first plate-like portion 81 is in contact with the distal end surface 51 of the fitting fixing portion 44. , 48, the fifth plate-like portion 85 and the fourth connecting portion 89 may be omitted. Alternatively, similarly, the terminal fitting 80 may be configured without the fifth plate-like portion 85, the fourth connecting portion 89, the fourth plate-like portion 84, and the third connecting portion 88. Alternatively, similarly, the terminal fitting 80 does not have the fifth plate-like portion 85, the fourth connecting portion 89, the fourth plate-like portion 84, the third connecting portion 88, the third plate-like portion 83, and the second connecting portion 87. It may be a configuration. In any of the above cases, as described in the present embodiment, the gap D1 is set so that the terminal fitting 80 can be fixed to the fitting fixing portion 44 in a state in which the first fitting surface 91 and the front end surface 51 are securely in contact with each other. What is necessary is just to set it as the structure which has -D3.

In this case, the electrode pads 47 and 48 of the metal fitting fixing part 44 are connected to the energization circuit of the substrate 40 by, for example, a harness. With such a configuration, the impact when the spring holder 70 contacts the terminal fitting 80 via the refill holder 30 every time the pen tip 16 is pressed is not directly transmitted to the substrate 40. Therefore, it can suppress that the load by vibration is applied to the electronic component attached to the electronic circuit containing the electricity supply circuit which the board | substrate 40 mounts.

  The electronic pen 3 includes a refill holder 30 so that the refill 15 can be replaced. However, the electronic pen 3 is not limited thereto, and a pen that does not perform writing with ink, such as a stylus pen, can also be used as the electronic pen.
