Further, in the method described in Patent Document 1, it is necessary to press-fit the grommet into the opening in the device assembly process. For this reason, there exists a problem that an assembly | attachment process becomes complicated.

  The objective of this invention is providing the electronic device and printing apparatus which can implement | achieve a countermeasure against static electricity noise, suppressing cost and facilitating an assembly process.

  An electronic apparatus according to a first aspect of the present invention includes a housing, a display member disposed in a display portion that is a part of the housing, and an input that is a part of a portion different from the display portion of the housing.

May be. In this case, even when the position of the input side portion of the conductive member is shifted in the direction orthogonal to the extending direction, the input side portion can be appropriately brought into contact with the ground of the control board.

  In the first aspect, the length of the input side portion in the direction orthogonal to the extending direction may be twice or more the length of the second extending portion in the extending direction. In this case, even when the position of the input side portion of the conductive member is greatly shifted in the extending direction, the input side portion can be appropriately brought into contact with the ground of the control board.

  In the first aspect, the input member may have a cutout portion through which the third extending portion passes. In a state where the third extending portion does not contact the input member, the third extending portion acts as a spring for biasing the input side portion toward the ground side of the control board. Therefore, the electronic apparatus can further appropriately contact the input side portion of the conductive member with the ground of the control board, so that the shielding effect against electrostatic noise can be enhanced.

  In the first aspect, the housing has a first projecting portion projecting inward on an inner wall surface, and the extending portion has a bent portion disposed along at least a part of the first projecting portion. May be. In this case, when the electronic device is assembled, the conductive member can be easily positioned with respect to the housing by bringing the bent portion into contact with the first protruding portion.

  In the first aspect, the ground may be a solid wiring disposed at least in a part near the peripheral edge of the control board. In this case, the potential of the conductive member can be stabilized by the ground. Therefore, the electronic device can enhance the shielding effect against electrostatic noise.

  1st aspect WHEREIN: The said display side part of the said electroconductive member may be fixed to the at least one part of the said display member with a double-sided tape. In this case, the position of the conductive member relative to the display member can be stabilized.

  The assembly process of the tape printer 1 will be described with reference to FIGS. First, the keypad 5 is arranged with respect to the upper housing 3. Next, the neutralizing plate 9 is disposed with respect to the upper housing 3. At this time, the bent portions 92F and 92G and the second portion 922 of the first extending portion 92A are adjusted so as to be arranged along the right side surface of the protruding portion 262. Is positioned. The display side portion 91 of the charge removal plate 9 and the first portion 921 of the first extending portion 92A are disposed so as to overlap the flat portion 260 of the upper plate 2A of the upper housing 3. The input side portion 93 and the second extending portion 92 </ b> B of the static elimination plate 9 are disposed so as to overlap the flat portion 52 </ b> A of the keypad 5.

  Next, the key board 6, the main board 7, and the LCD 8 are arranged with respect to the upper housing 3. The display side portion 91 of the charge removal plate 9 and the first portion 921 of the first extending portion 92A are sandwiched between the LCD 8 and the upper plate 2A. At this time, the display side portion 91 is affixed to the LCD 8 with a double-sided tape. As a result, the position of the charge removal plate 9 with respect to the LCD 8 is fixed. Further, the input side portion 93 and the second extending portion 92 </ b> B of the charge removal plate 9 are sandwiched between the key substrate 6 and the keypad 5. The input side portion 93 and the second extending portion 92 </ b> B are pressed against the key substrate 6.

  Next, the screws 65 </ b> A to 65 </ b> D are inserted from the lower side to the upper side of the insertion portions 64 </ b> A to 64 </ b> D of the key substrate 6. The screws 65 </ b> A to 65 </ b> D enter the insertion portions 64 </ b> A to 64 </ b> D of the key board 6 and the insertion portions 5 </ b> A to 5 </ b> D of the keypad 5 from the lower side to the upper side, and are provided on the upper plate 2 </ b> A of the upper housing 3. It is screwed into each recessed part of protrusion part 251A-251D. When the screws 65 </ b> A to 65 </ b> D are tightened, a force acts on the key substrate 6 and the upper plate 2 </ b> A in directions close to each other. The keypad 5 between the key board 6 and the upper plate 2A is compressed. In this case, the keypad 5 uses an elastic force to separate the input side portion 93 and the second extending portion 92B of the static elimination plate 9 sandwiched between the flat portion 52A of the keypad 5 and the key substrate 6 by the elastic force. Press firmly against 6. Thereby, the input side portion 93 and the second extending portion 92B and the rear end ground portion 62A of the key board 6 are in strong electrical contact.

  Next, the screw 651A is inserted into the insertion portion 71A of the support member 71 from the lower side to the upper side. Screws 651B are inserted through the insertion portion 72A of the support member 72 from the lower side toward the upper side. The screws 651A and 651B are screwed into the respective concave portions of the protruding portions 261A and 261B provided on the upper plate 2A of the upper housing 3. As a result, the support members 71 and 72 are fixed to the upper housing 3. The main board 7 is held in parallel with the key board 6. Next, the lower housing 4 is fitted to the upper housing 3 from the lower side. Thus, the assembly process of the tape printer 1 is completed.

  As described above, in the tape printer 1, the keypad 5 and the key substrate 6 are pressed against each other when the screws 65A to 65D are tightened, so that each of the depressed key portions 51 is detected. Can be detected. As a result, a CPU (not shown) provided on the main board 7 can specify a character or the like corresponding to the pressed key portion 51, and the tape printer 1 can be used. Further, the input side portion 93 and the second extending portion 92B of the neutralizing plate 9 are in contact with the rear end ground portion 62A of the ground 62 of the key substrate 6 in a state where the keypad 5 and the key substrate 6 are in pressure contact with each other. The keypad 5 is made of rubber and has elasticity. For this reason, the input side portion 93 and the second extending portion 92B of the static elimination plate 9 are strongly pressed against the rear end ground portion 62A of the key board 6, so that it is more securely connected to the ground 62 of the key board 6 more electrically. To do.

  Further, the display side portion 91 of the charge removal plate 9 is disposed above a portion of the rear end portion of the element portion 81 of the LCD 8 and a portion excluding the left and right end portions of the drive portion 82. For this reason, the neutralizing plate 9 acts as a shield for shielding the LCD 8 from static noise entering from the outside of the housing 2. Here, as described above, the input side portion 93 and the second extending portion 92 </ b> B of the static elimination plate 9 are more reliably electrically connected to the ground 62 of the key substrate 6. For this reason, since the electric potential of the static elimination board 9 is stabilized, the static elimination board 9 functions appropriately as a shield member of electrostatic noise.

  The input side portion 93 and the second extending portion 92B of the static elimination plate 9 are in contact with the ground 62 of the key substrate 6 in the process of pressing the key substrate 6 and the keypad 5 together. For this reason, when the keypad 5 and the key substrate 6 are pressed into contact with the screws 65A to 65D in the process of assembling the tape printer 1, the input side portion 93 and the second extending portion 92B of the static elimination plate 9 are simultaneously connected to the key substrate 6 Can be brought into contact with the ground 62. Therefore, it is possible to realize the effect of shielding static electricity noise by the charge removal plate 9 while facilitating the assembly of the tape printer 1. Further, since the tape printer 1 uses the static elimination plate 9 having a simple plate-like structure as a shield against electrostatic noise, it is possible to realize a countermeasure against electrostatic noise while suppressing cost.

  Conventionally, in the tape printer 1, a part of the static elimination plate 9 is bent, and an urging force in the direction toward the ground 62 of the key substrate 6 is applied to the input side portion 93, and only the urging force is applied to the key substrate 6. The input side portion 93 is in contact with the ground 62. However, in this case, in order to appropriately apply an urging force to the input side portion 93, it is necessary to firmly fix the display side portion 91 of the charge removal plate 9 to the LCD 8, and it is not sufficient to bond with the double-sided tape alone. Therefore, the assembly of the tape printer 1 may be complicated. On the other hand, in the above-described embodiment, the input side portion 93 and the second extending portion 92 </ b> B of the static elimination plate 9 are in pressure contact with the keypad 5 and the key substrate 6 and are in contact with the key substrate 6. For this reason, it is not necessary to strongly fix the display side portion 91 to the LCD 8 as in the prior art. Accordingly, even when the display side portion 91 is fixed to the LCD 8 by a simple method such as fixing with a double-sided tape, the input side portion 93 and the second extending portion 92B can be properly brought into contact with the ground 62. Therefore, assembly can be facilitated in the manufacturing process of the tape printer 1.

  The LCD 8 is disposed below the window portion 27. For this reason, the LCD 8 is easily affected by external static electricity noise. Further, since the driver for controlling the display of the liquid crystal display element of the element part 81 is disposed in the drive part 82 of the LCD 8, it is particularly susceptible to the influence of electrostatic noise. On the other hand, in the above embodiment, the display side portion 91 of the static elimination plate 9 is disposed above a portion of the rear end portion of the element portion 81 of the LCD 8 and the portion excluding the left and right end portions of the drive portion 82. .

The fourth portion 924 of the third extending portion 92C extends along a plane that intersects the plane on which the display side portion 91 and the input side portion 93 extend. In this case, the bent portions 92 </ b> D and 92 </ b> E of the charge removal plate 9 act as springs for urging the input side portion 93 and the second extending portion 92 </ b> B toward the ground 62 side of the key substrate 6. Therefore, the tape printer 1 can more appropriately bring the input side portion 93 and the second extending portion 92 </ b> B of the static elimination plate 9 into contact with the ground 62 of the key substrate 6. For this reason, the tape printer 1 can enhance the shielding effect against electrostatic noise.

  In the above embodiment, the length in the front-rear direction of the input side portion 93 of the static elimination plate 9 is about twice as long as the length in the front-rear direction of the second extending portion 92B. In this case, even when the positions of the input side portion 93 and the second extending portion 92 </ b> B of the static elimination plate 9 are shifted in the front-rear direction, at least the input side portion 93 can be appropriately brought into contact with the ground 62 of the key board 6.

  In the above embodiment, the keypad 5 has the notch portion 521A. The cutout portion 521A can suppress the fourth portion 924 of the third extending portion 92C from contacting the keypad 5. In this case, the action of the bent portions 92D and 92E of the third extending portion 92C as a spring is not inhibited by the keypad 5. Therefore, the tape printer 1 can further appropriately bring the input side portion 93 of the charge removal plate 9 into contact with the ground 62 of the key substrate 6, so that the shielding effect against electrostatic noise can be enhanced.

  In the above embodiment, the neutralization plate 9 is positioned in the left-right direction so that the second portion 922 of the first extending portion 92A and the bent portions 92F, 92G are arranged along the right side surface of the protruding portion 262. It is executed by being adjusted. For this reason, when the tape printer 1 is assembled, the neutralization plate 9 can be easily positioned in the left-right direction with respect to the housing 2 by bringing the second portion 922 and the bent portions 92F and 92G into contact with the protruding portion 262.

  In the above-described embodiment, the ground 62 is a solid wiring that is disposed in the vicinity of the right end portion of the rear end, right end, left end, and front end of the key board 6 and the inside of the left end portion of the front end. The line width of the ground 62 indicates a wide range of signal line patterns that are not confined to signal lines on a normal printed circuit board. In this case, the ground 62 can further stabilize the potential of the charge removal plate 9 that is in contact via the rear end ground portion 62A. Therefore, the tape printer 1 can further enhance the shielding effect against electrostatic noise.

  In the said embodiment, the display side part 91 of the static elimination board 9 is affixed and fixed to LCD8 with a double-sided tape. For this reason, since the tape printer 1 can stabilize the position of the charge removal plate 9 with respect to the LCD 8, the assembling work of the tape printer 1 can be further facilitated.
