Electronic equipment and component installation method

The present invention relates to an electronic device and a method for mounting a component. [Cross-reference to related applications] This application claims priority and rights to Japanese Patent Application No. 2022-048056 filed on March 24, 2022. The specification, patent scope and all drawings of Japanese Patent Application No. 2022-048056 are cited as references in this specification.

Most electronic devices have buttons on the surface of the housing, and the buttons are used as operating components to switch switches such as a touch switch disposed in the housing. A typical example of a button is a button associated with switching the power of the electronic device on or off.

The switch in the frame and the key for switching the switch are usually arranged in the extended direction of the pressing direction (operation direction) under the key (for example, refer to Japanese Patent Publication No. 2007-42431).

[Problems to be solved by the invention]

In an electronic device in which a switch in a housing is turned on and off by a key, it is sometimes difficult to arrange the switch in a direction extending from the direction in which the key is pressed due to restrictions on the arrangement of various parts such as a printed circuit board in the housing. In addition, depending on the positional relationship between the switch and the key as an operating member for the switch, it is sometimes difficult to efficiently perform the assembly work of the electronic device, which includes the work of mounting the operating member on the housing.

One aspect of the present invention is to provide a technique for easily installing the operating member of a switch in an operating frame on the frame. [Means for solving the problem]

An electronic device of one embodiment is characterized by comprising: a device frame; a switch disposed in an internal space of the device frame; and an operating member having a switch operating portion for operating the switch, a key portion located in a through hole of the device frame, a rotating shaft engaged with a supporting portion provided in the device frame, and a contact portion capable of contacting the device frame and being movable relative to the device frame. The device body rotates around the aforementioned rotating shaft and is supported by the aforementioned supporting portion so as to be movable in a direction orthogonal to the axial direction of the aforementioned rotating shaft; the aforementioned device frame and the aforementioned operating member are configured in such a manner that when the aforementioned key portion and the aforementioned operating member rotate together with the aforementioned rotating shaft as the center when the aforementioned abutting portion abuts against the aforementioned device frame, the aforementioned through hole is located on the rotation track of the aforementioned key portion. [Effect of the invention]

According to the above aspects, the operation of installing the operating member of the switch in the operating frame into the frame can be easily performed.

[Form used to implement the invention]

Hereinafter, the embodiment of the present invention will be described with reference to the drawings. In the following description, a printing device for printing on a tape-shaped printed medium to produce a label is cited as an example of an electronic device, but the electronic device of the present invention is not limited to such a printing device.

In addition, the purpose of referring to the X direction, Y direction and Z direction shown in the respective figures is to clarify the corresponding relationship between the directions and surfaces of the printing devices between the figures.

Fig. 1 is a top view showing an example of the external structure of a printing device of an embodiment. Fig. 2 is a schematic diagram for explaining the relationship between switches and operating components in the printing device shown in Fig. 1. Fig. 2 schematically shows the relationship between switches, operating components and the frame of the printing device shown in Fig. 1 when the frame is cut along the line A-A' and viewed from the right side.

The printing device 1 illustrated in FIG1 includes a first frame part 2, a second frame part 3 and a third frame part 4. The second frame part 3 is mounted on one side of the first frame part 2, and the third frame part 4 is mounted on the other side of the first frame part 2. A box-shaped frame is formed, and the box-shaped frame has an internal space, and the internal space can accommodate electronic parts such as a printed circuit board, a conveying mechanism for conveying a strip-shaped printed medium, a printing mechanism for printing the printed medium, and a paper tape cassette for accommodating a reel of a strip-shaped printed medium. The frame of the printing device 1 is constructed in a manner that the paper tape cassette can be detached. For example, the second frame part 3 can be detached and assembled relative to the first frame part 2, and the paper tape cassette can be detached and assembled (exchangeable) by removing the second frame part 3 from the first frame part 2.

A printed circuit board 5 and an operating member 6 are provided in the frame of the printing device 1. The printed circuit board 5 is mounted with various electronic components including a touch switch 501 for turning on/off the power supply. The operating member 6 is used for the user to turn on/off the touch switch 501. The operating member 6 is rotatably mounted on the first frame part 2, and a part of the operating member 6 (key portion 610) is inserted into a through hole 210 formed in the first frame part 2. The operating member 6 is mounted on the first frame part 2 in a manner that it can rotate around a rotation axis, and the rotation axis has a direction (Y direction) that is orthogonal to the direction (-Z direction) of the pressure load applied by the user pressing the key portion 610 as an axial direction. The operating member 6 and the touch switch 501 are configured in such a way that a portion of the operating member 6 different from the key portion 610 (the switch operating portion 620) contacts the touch switch 501 to perform a switch operation, and the operating member 6 rotates by applying a pressing load to the key portion 610 from outside the printing device 1.

In the example shown in FIG. 1 and FIG. 2 , the operating member 6 has a flat base 600 whose plane shape is a sector with a top angle of 90 degrees, and a rotation axis 630 is provided at the top corner of the base 600. The rotation axis 630 of the operating member 6 is provided in such a manner that the axis direction (the extension direction of the axis Rx) becomes the normal direction of the sector plane 601 (hereinafter referred to as the "first main surface 601") of the base 600. The operating member 6 is rotatably supported by the first frame part 2 by fitting the rotation axis 630 with the support part 230 provided in the first frame part 2 as the part inside the frame.

A button portion 610 and a limiting portion 604 are provided on a first side surface 603 extending from the rotation axis 630 toward the first radial direction of the base portion 600 of the operating member 6. The button portion 610 is provided, for example, in a manner of protruding from the first side surface 603 toward the first radial direction in a tangential direction of an arc centered at the axis Rx. The operating member 6 is provided with potential energy in a rotation direction opposite to the rotation direction when the button portion 610 is pressed (counterclockwise in FIG. 2 ) by an elastic member such as a torsion spring (not shown), for example. The limiting portion 604 is a portion that makes the operating member 6 to which potential energy is applied contact with the first frame part 2 to limit the rotation of the operating member 6 in the direction of potential energy application, and determines the reference position (position when not subjected to a pressing load from outside the printing device 1) of the key portion 610 inserted into the through hole 210 of the first frame part 2. The limiting portion 604 is formed, for example, with a dimension that the tangent direction of the arc in the first radial direction with the axis Rx as the center is substantially parallel to the pressing direction of the key portion 610 when contacting the first frame part 2.

A switch operating portion 620 is provided on a second side surface 605 extending from the rotation axis 630 of the base 600 of the operating member 6 toward the second radial direction. The switch operating portion 620 is provided, for example, in a manner of protruding from the second side surface 605 in a tangential direction of an arc centered on the axis Rx in the second radial direction. A touch switch 501 is arranged in an extension direction of the protruding direction of the switch operating portion 620. If the user of the printing device 1 presses the key portion 610 to rotate the operating member 6, the switch operating portion 620 contacts the touch switch 501. If the key portion 610 is not pressed, the switch operating portion 620 separates from the touch switch 501 due to the application of the aforementioned potential energy. The contact and separation of the switch operating part 620 form a switching operation on the touch switch 501.

By using such an operating member 6 to switch the touch switch 501, the touch switch 501 can be arranged at a position different from directly below the key portion 610. Therefore, for example, the number of parts and the number of working steps required to electrically connect the wiring of the printed circuit board 5 shown in FIG. 2 to the touch switch 501 can be reduced.

In the operation of mounting the operating member 6 on the first frame part 2, the support part 230 of the first frame part 2 supports (fits) the rotation shaft 630 of the operating member 6 and the key part 610 is inserted into the through hole 210 of the first frame part 2. In order to effectively perform such an operation, the support part 230 of the first frame part 2 is not formed into a hole shape corresponding to the rotation shaft 630 of the operating member 6, but is formed into a groove shape that allows the rotation shaft 630 to enter and exit by moving the rotation shaft 630 in a direction orthogonal to the axis direction.

However, if a key portion 610 protruding in the tangential direction of an arc with the axis Rx as the center in the first radial direction is provided on the first side surface 603 extending in the first radial direction of the base 600 of the operating member 6, it takes time to insert the key portion 610 into the through hole 210 of the first frame part 2, which may reduce the working efficiency.

Fig. 3 is a diagram illustrating one example of the main reason for the reduced efficiency of the operation of installing the operating member on the first device frame. The structure of the first frame part 2 and the operating member 6 illustrated in Fig. 3 is the same as the structure of the first frame part 2 and the operating member 6 of the present embodiment, except that it does not have the position adjustment mechanism described later with reference to Figs. 4 to 13.

For example, as shown in Figure 3, the supporting portion 230 of the first frame part 2 is formed in the shape of a groove in which the entry direction of the rotating shaft 630 of the operating member 6 is along the direction of the first frame part 2 approaching the through hole 210, and the deepest part of the groove is located at the following position: the position where the key portion 610 of the operating member 6 abuts against the rotating shaft 630 when the key portion 610 of the operating member 6 is inserted into the through hole 210 and the limiting portion 604 abuts against the first frame part 2.

The operation of mounting the operating member 6 on the first frame part 2 is performed, for example, by placing the first frame part 2 on a workbench with the entrance of the groove-shaped support part 230 facing upward. In this operation, first, the rotation axis 630 of the operating member 6 enters the support part 230 of the first frame part 2, and then, the operating member 6 is rotated to insert the key part 610 of the operating member 6 into the through hole 210 of the first frame part 2.

When the first frame part 2 and the operating member 6 are not provided with the position adjustment mechanism described later, as shown in Figure 3, when the rotation axis 630 of the operating member 6 is located at the bottom (deepest part) of the support part 230, the distance LA1 between the axis Rx and the part of the key part 610 farthest from the axis Rx, i.e., the first key end 610a, is greater than the distance LB1 between the axis Rx and the part of the opening end on the inner side of the frame of the through hole 210 farthest from the axis Rx, i.e., the first through hole end 210a. Therefore, in order to insert the button portion 610 into the through hole 210, the rotation shaft 630 of the operating member 6 needs to be displaced in the direction of the entrance of the support portion 230, and it takes time to adjust the displacement amount, thereby reducing the working efficiency.

In order to suppress the reduction in efficiency of the installation operation of the operating component 6 caused by the distance LA1 between the aforementioned axis Rx and the first key end 610a of the key portion 610, in the printing device 1 of this embodiment, a position adjustment mechanism as described below is set on the first frame part 2 and the operating component 6.

Fig. 4 is a perspective view of an operating member of an embodiment. Fig. 5 is a perspective view of a portion of a first frame part of an embodiment on which the operating member is mounted. Fig. 6 is a partial cross-sectional top view illustrating the correspondence between the various parts of the operating member and the various parts of the first frame part. The X' direction, Y' direction, and Z' direction of Fig. 4 are directions associated with the operating member 6 shown in the figure, and the operating member 6 is mounted on the first frame part 2 in such a way that the Y' direction is substantially the same as the Y direction associated with the printing device 1 in other figures.

As described above, the operating member 6 of the present embodiment includes a base 600, a key portion 610, a switch operating portion 620, and a rotation axis 630. In addition, a rib 640 including a portion of a position adjustment mechanism is provided on the first main surface 601 of the base 600 and the second main surface 602 facing the opposite side of the first main surface 601. The rib 640 includes a first portion 641, a second portion 642, and a third portion 643. The first portion 641 is located near the switch operating portion 620 on the first main surface 601 and the second main surface, and is used to suppress deformation (e.g., twisting, etc.) of the base 600 and suppress positional deviation of the switch operating portion 620 in the axial direction. The second portion 642 (contact portion) is located near the key portion 610 of the first main surface 601 and the second main surface 602, and is used to suppress deformation of the base 600 and function as a part of the position adjustment mechanism. The third portion 643 is located between the first portion 641 and the second portion 642, and is used to suppress deformation of the base 600.

In the first frame part 2 of the present embodiment, the portion where the operating member 6 is mounted is provided with a pair of wall portions 241 and 242 having a supporting portion 230 and a pair of limiting portions 251 and 252 located between the pair of wall portions 241 and 242 and functioning as a part of the position adjustment mechanism. The pair of wall portions 241 and 242 and the pair of limiting portions 251 and 252 may be a portion formed integrally with the portion where the through hole 210 is formed, or may be a portion formed separately.

In the rib 640 of the operating member 6 illustrated in FIG. 4 and FIG. 6 , the heights of the first portion 641 and the second portion 642 from the first main surface 601 (or the second main surface 602) are the same and higher than the height of the third portion 643. Furthermore, as illustrated in FIG. 6 , the pair of wall portions 241 and 242 on which the operating member 6 is mounted are arranged so that the distance (gap) between the wall portions is substantially the same as the distance from the upper end of the second portion 642 of the first main surface 601 of the operating member 6 to the upper end of the second portion 642 of the second main surface 602. With such a configuration, the positional deviation of the operating member 6 in the axial direction between the pair of wall portions 241 and 242 can be suppressed, and the occurrence of poor rotation of the operating member 6 due to the increase in the contact area between the pair of wall portions 241 and 242 and the rib 640 of the operating member 6 can be suppressed.

In addition, the third portion 643 of the rib 640 of the operating member 6 illustrated in FIG. 4 and FIG. 6 extends along an arc centered on the axis Rx, and the second portion 642 includes a portion displaced radially outward from a position corresponding to the extension line of the arc of the third portion 643. The second portion 642 abuts against a pair of limiting portions 251 and 252 provided on the first frame part 2 during the process of inserting the key portion 610 of the operating member 6 into the through hole 210 of the first frame part 2 after the rotation shaft 630 enters the support portion 230. The second portion 642 of the operating member 6 and the pair of limiting portions 251 and 252 of the first frame part 2 are formed in such a manner that the position of the key portion 610 can be adjusted, wherein the position is the position of each portion of the key portion 610 relative to the position of the through hole 210 when the opening end of the frame inner side of the through hole 210 of the first frame part 2 passes through. The pair of limiting portions 251 and 252 illustrated in FIG. 4 to FIG. 6 are formed in such a manner that the distance (gap) between the limiting portions is greater than the distance corresponding to the thickness of the base 600 (the distance from the first main surface 601 to the second main surface 602), and a portion of each limiting portion overlaps with the base 600 of the installed operating member 6. The relationship between the second portion 642 of the operating member 6 and a pair of limiting portions 251 and 252 of the first frame part 2 will be explained later with reference to Figures 8 to 11.

Fig. 8 is a side sectional view (part two) illustrating a method for mounting an operating member toward a first frame part in an implementation form. Fig. 9 is a side sectional view (part three) illustrating a method for mounting an operating member toward a first frame part in an implementation form. Fig. 10 is a side sectional view (part four) illustrating a method for mounting an operating member toward a first frame part in an implementation form. Fig. 11 is a side sectional view (part five) illustrating a method for mounting an operating member toward a first frame part in an implementation form. Fig. 12 is a side sectional view (part six) illustrating a method for mounting an operating member toward a first frame part in an implementation form. Fig. 13 is a side cross-sectional view (part 7) of an embodiment of the method for mounting the operating member toward the first frame part. In Fig. 7 to Fig. 13, "Rx" indicates the axis center of the rotation axis 630 of the operating member 6, and "Px" indicates the axis center of the rotation axis of the operating member 6 when the deepest side of the support portion 230 supports the rotation axis 630.

For example, as shown in Figure 7, the supporting portion 230 of the first frame part 2 is formed in the shape of a groove in which the entry direction of the rotating shaft 630 of the operating member 6 is along the direction of the first frame part 2 approaching the through hole 210, and the deepest part of the groove is located at the following position: the position where the key portion 610 of the operating member 6 abuts against the rotating shaft 630 when the key portion 610 of the operating member 6 is inserted into the through hole 210 and the limiting portion 604 abuts against the first frame part 2 (refer to Figure 13).

The operation of mounting the operating member 6 on the first frame part 2 is performed, for example, in a state where the first frame part 2 is placed on a workbench in a manner that the entrance of the groove-shaped support part 230 faces upward. In this operation, first, as shown in FIG. 7 , the rotation shaft 630 of the operating member 6 is made to enter the support part 230 of the first frame part 2. When the rotation shaft 630 enters the deepest part of the support part 230, as shown in FIG. 7 , the second portion 642 of the rib 640 of the operating member 6 can be in a state of being separated from the pair of limiting parts 251 and 252.

After the rotating shaft 630 enters the deepest part of the supporting part 230, if the operating member 6 is rotated in the direction of inserting the key part 610 into the through hole 210 of the first frame part 2 (counterclockwise in Figure 7), as shown in Figure 8, the second portion 642 of the rib 640 of the operating member 6 abuts against a pair of limiting parts 251 and 252 in a manner in which the external force from each limiting part 251 and 252 is received in the direction of displacing the rotating shaft 630 toward the entrance of the supporting part 230. By moving the axis Rx of the rotating shaft 630 of the operating member 6 toward the entrance side of the support portion 230 by a distance Δx from the axis position Px of the deepest part of the support portion 230, the orbit of the first key end 610a, which is the part farthest from the axis Rx of the key portion 610 when the operating member 6 rotates around the axis Rx, becomes closer to the first through hole end 210a on the frame inner side of the through hole 210 of the first frame part 2 farthest from the axis position Px, compared to the orbit when the axis Rx is at the axis position Px. The second portion 642 of the rib 640 and a pair of limiting portions 251 and 252 of the first frame part 2 are arranged in such a manner that the distance Δx between the axis Rx and the axis position Px before the key portion 610 enters the through hole 210 as shown in FIG. 8 is within the range within which the portion of the key portion 610 that initially enters the through hole 210 can enter the through hole 210.

If the operating member 6 is rotated to allow a portion of the key portion 610 to enter the through hole 210, as shown in FIG9 , the first key end portion 610a of the key portion 610 is close to the opening end of the through hole 210 on the inner side of the frame. At this time, in order to allow the first key end portion 610a of the key portion 610 to enter the through hole 210, the rotation shaft 630 movable in the support portion 230 is moved to a position where the distance LB1 from the axis Rx to the first through hole end portion 210a of the through hole 210 is longer than the distance LA1 from the axis Rx to the first key end portion 610a. That is, the second portion 642 of the rib 640 and the pair of limiting portions 251 and 252 of the first frame part 2 are arranged as shown in Figure 9, so that the distance LA2 from the axis Rx to the abutment position of the second portion 642 of the rib 640 and the pair of limiting portions 251 and 252 of the first frame part 2 before the first key end 610a of the key part 610 is about to enter the through hole 210, and the distance LA1 from the axis Rx to the first key end 610a of the key part 610 are in a relationship of LA2≧LA1.

If the operating member 6 is further rotated to make the first key end 610a of the key portion 610 enter the through hole 210, as shown in FIG10 , the second key end 610b, which is the portion closest to the axis Rx of the key portion 610, approaches the opening end of the inner side of the frame of the through hole 210. At this time, in order to make the second key end 610b of the key portion 610 enter the through hole 210, it is sufficient to move the rotation axis 630 movable in the support portion 230 to the following position: the distance LB3 from the axis Rx to the portion of the through hole 210 closest to the axis Rx, i.e., the second through hole end 210b, is shorter than the distance LA3 from the axis Rx to the second key end 610b. That is, the second portion 642 of the rib 640 and the pair of limiting portions 251 and 252 of the first frame part 2 are arranged in such a manner that the distance LB3 from the axis Rx to the second through hole end 210b of the through hole 210 before the second key end 610b of the key part 610 enters the through hole 210 and the distance LA3 from the axis Rx to the second key end 610b of the key part 610 are LA3≧LB3 as shown in FIG. At this time, the distance LA4 from the axis Rx to the contact position between the second portion 642 of the rib 640 and the pair of limiting portions 251 and 252 of the first frame part 2 is generally less than the distance LA2 described with reference to FIG. 9 (i.e., LA4≦LA2).

If the operating member 6 is further rotated to make the second key end 610b of the key portion 610 enter the through hole 210, the key portion 610 abuts against the inner wall of the through hole 210, so that the movement of the key portion 610 in the direction parallel to the opening end face of the through hole 210 (in the XY plane) can be restricted. After the second key end 610b of the key portion 610 enters the through hole 210, as shown in Figures 11 to 13, when the operating member 6 abuts against the first frame part 2 at the limiting portion 604 and the key portion 610 reaches the position of the opening end on the frame outer side of the through hole 210, the operation of installing the operating member 6 toward the first frame part 2 is completed. After the second key end 610b of the key portion 610 enters the through hole 210, the operating member 6 continues to rotate while the movement of the key portion 610 in the XY plane is limited by the inner wall of the through hole 210, and the rotation shaft 630 moves toward the deepest part of the support portion 230. Therefore, as shown in Figures 11 to 13, the second portion 642 of the rib 640 and the pair of limiting portions 251 and 252 of the first frame part 2 are arranged in a manner that allows the rotation shaft 630 to move toward the deepest part of the support portion 230 after the second key end 610b of the key portion 610 enters the through hole 210, and the second portion 642 is separated from each limiting portion 251 and 252.

After the operating member 6 is mounted on the first frame part 2, the remaining predetermined assembly operations are performed, and the printing device 1 is completed with the key portion 610 located in the through hole 210 as shown in FIG. 1 and FIG. 2. In the completed printing device 1, as shown in FIG. 13, the limiting portions 251, 252 of the first frame part 2 have a portion extending toward the axis Rx side relative to the rotation track of the second portion 642 of the rib 640 of the operating member 6 around the axis Rx. In other words, the completed printing device 1 has the following portion: a portion that overlaps with the main surface of the base 600 of the operating member 6 at a position opposite to the key portion 610 with the second portion 642 of the rib 640 of the operating member 6 as a boundary, and a portion that is shorter than the distance from the axis Rx of the rotating shaft 630 to the second portion 642 of the operating member 6.

As described above, in the printing device 1 of the present embodiment, when the rotating shaft 630 is rotated by the operating member 6 supported by the supporting portion 230 of the first frame part 2, the second portion 642 of the rib 640 of the operating member 6 is brought into contact with the limiting portions 251 and 252 of the first frame part 2 in such a manner that the key portion 610 of the operating member 6 can easily enter the through hole 210 of the first frame part 2, thereby changing the position of the rotating shaft 630 in the supporting portion 230. Therefore, in the operation of mounting the operating member 6 on the first frame part 2, the position of the rotating shaft 630 for inserting the key portion 610 into the through hole 210 of the first frame part 2 can be automatically adjusted, thereby suppressing the reduction of the operation efficiency.

The combination of the shape (size) of the second portion 642 and the pair of limiting portions 251 and 252 that meet the aforementioned conditions for realizing the installation operation of the operating member 6 toward the first frame part 2 described with reference to FIGS. 7 to 13 is not limited to a specific combination. For example, it can be appropriately changed according to the size relationship between the key portion 610 of the operating member 6 and the through hole 210 of the first frame part 2, the shape of the key portion 610, the position of the second portion 642 in the first main surface 601 (and the second main surface 602) of the base 600 of the operating member 6 and the position relationship between the limiting portions 251 and 252, etc. By optimizing the aforementioned position adjustment mechanism, the gap between the key portion 610 after the operating member 6 is installed and the inner wall of the through hole 210 of the first frame part 2 can be set to the required minimum limit, for example, dust can be prevented from entering the interior of the frame.

The aforementioned implementation form is only an example for easy understanding of the invention. That is, the installation mechanism of the operating component and the electronic device of the present invention are not limited to the aforementioned implementation form, and various modifications and changes can be made within the scope of the description that does not exceed the scope of the patent application.

For example, in the aforementioned embodiment, as shown in FIG. 9 , the first key end 610a of the key portion 610 of the operating member 6 which is farthest from the axis Rx of the rotation axis 630 is located on the outer side of the through hole 210, and the distance LA1 from the axis Rx to the first key end 610a when located close to the through hole 210 and the distance LB1 from the axis Rx to the first through hole end 210a which is farthest from the axis Rx at the opening end on the inner side of the frame of the through hole 210 are LA1≦LB1, and the second portion 642 of the operating member 6 and the limiting portions 251, 252 of the first frame part 2 are provided. However, the second portion 642 of the operating member 6 and the limiting portions 251, 252 of the first frame part 2 can be arranged in the following manner: the first key end 610a is located on the outer side of the through hole 210, and the absolute value of the difference between the distance LA1 from the axis Rx to the first key end 610a when the first key end 610a is located close to the through hole 210 and the distance LB1 from the axis Rx to the first through hole end 210a is smaller than the absolute value of the difference between the distance from the axis Rx to the first key end 610a and the distance from the axis Rx to the first through hole end 210a when the key portion 610 is located in the through hole 210. If the first key end 610a is located on the outer side of the through hole 210 and the distance between the first key end 610a and the first through hole end 210a when the first key end 610a is located close to the through hole 210 (i.e., before entering the through hole 210) is smaller than the distance in the case illustrated in FIG. 3 without a position adjustment mechanism, the first key end 610a can easily enter the through hole 210.

For example, the position adjustment mechanism of the electronic device of the present invention is not limited to the combination of the second portion 642 of the rib 640 of the operating member 6 and a pair of limiting portions 251 and 252 of the first frame part 2, and can be appropriately changed. For example, the portion of the operating member 6 that abuts against the limiting portions 251 and 252 of the first frame part 2 in order to change the position of the axis Rx of the rotation shaft 630 is not limited to the second portion 642 provided as a part of the rib 640, but may also be a portion provided separately from the rib 640. For example, the portion of the operating member 6 that abuts against the limiting portions 251 and 252 of the first frame part 2 in order to change the position of the axis Rx of the rotation shaft 630 may also be a columnar portion provided at a position where the rib of the second portion 642 that does not displace in the outward direction is located in the outward direction, such as shown in FIG. 3. In addition, a portion of the base 600 of the operating member 6 may be expanded in the outward direction, and the expanded portion may be brought into contact with the limiting portions corresponding to the limiting portions 251 and 252 of the first frame part 2 to change the position of the axis Rx of the rotation axis 630.

Furthermore, the electronic device of the present invention is not limited to a printing device for printing on a strip-shaped printed medium, and any device having an operating member for performing a switch operation on a switch disposed inside a frame such as a touch switch is sufficient. Furthermore, the switch operation of the operating member is not limited to the on/off operation of the power supply, and may be other operations. Thus, the electronic device of the present invention can be used in various applications such as computers, communication devices, digital cameras, electronic products, household appliances, and car navigation devices.
