Description

  The present invention relates to a small electric device having a built-in battery such as a face shaver, an electric toothbrush, an electric nail polisher, a flashlight, and a heated eyelash shaping tool.

  In the small electric device of the present invention, a band-shaped fixed electrode lead is disposed along the outer peripheral surface of the battery chamber. This type of structure is disclosed in, for example, Patent Document 1. Here, as shown in FIG. 21, a fixed electrode lead 92 made of sheet metal is arranged along the outer surface of the peripheral wall of the inner case 91 provided with the battery chamber 90. A terminal portion 93 for connecting the positive electrode of the battery is bent at the lower end of the fixed electrode lead 92. The terminal portion 93 is inserted into the battery chamber 90 from a terminal window 94 opened in the lower peripheral surface of the inner case 91. A lead recess 95 for loading the fixed electrode lead 92 is formed in the peripheral surface of the inner case 91.

Japanese Unexamined Patent Publication No. 2002-219287 (paragraph number 0018, FIG. 8) JP 2001-120334 A (paragraph number 0027, FIG. 6)

  In the face shaver of Patent Document 1, as shown in FIG. 21, an inner case 91 is placed on a workbench, and a battery terminal portion 93 is inserted into a battery chamber 90 from a terminal window 94 so that a fixed electrode lead is inserted. 92 is temporarily assembled to the inner case 91. Therefore, in the process of inserting the terminal portion 93 into the terminal window 94, it is not possible to visually recognize whether the terminal portion 93 has been inserted properly. In order to confirm that the assembling is proper, it is necessary to temporarily assemble the fixed electrode lead 92 and then turn the inner case 91 up and down to visually recognize the state of the terminal portion 93, which takes extra time. Also, due to variations in the external dimensions of the battery terminal portion 93 and the terminal window 94, it becomes difficult to insert the terminal portion 93 into the terminal window 94, or the terminal portion 93 inserted into the terminal window 94 wobbles in the thickness direction. The contact state with the battery may become unstable. Also in Patent Document 2, there is a similar problem regarding the assembly of the fixed electrode lead 92.

  An object of the present invention is to provide a compact electric device that can reliably and easily assemble a fixed electrode lead with respect to an inner case and can be assembled in a state in which there is no room for the connection terminal portion to wobble with respect to the inner case. It is in.

In the small electric device according to the present invention, the main body case 1 is opened / closed by inserting / removing the battery case 12 into / from the inner case 1 </ b> A with the battery case 12 having an inlet / outlet 15 for taking in / out the battery 5. And an outer case 1B, and the inner case 1A is provided with a small electrical device provided with a switch structure for turning on / off the output state of the battery 5 accommodated in the battery chamber 12. The switch structure includes a fixed electrode lead 28 arranged along the longitudinal direction of the peripheral wall of the battery chamber 12, the first switch terminal 35 and the second switch terminal 30, and the first and second switch terminals 30 and 35. A switch piece 31 for turning on / off the conductive state and an operation tool 6 disposed on the outer surface of the inner case 1B for switching the switch piece 31 are included. A connection terminal 36 that circumscribes either the positive electrode or the negative electrode of the battery 5 is formed at one end of the fixed electrode lead 28. A loading opening 47 is formed from the bottom wall 46 to the peripheral wall of the battery chamber 12, and the loading opening 47 communicates with the entrance / exit 15 to divide the bottom wall 46 .

  The bottom wall 46 of the battery chamber 12 is divided into left and right by a loading opening 47 formed at the left and right center of the bottom wall 46. A pair of receiving ribs 53 are formed on the inner surface of the dividing wall divided by the loading opening 47, and both sides of the connection terminal 36 loaded in the loading opening 47 are supported by the receiving ribs 53 formed on the inner surface of the dividing wall (FIG. 6). reference).

  The facing surface of the receiving rib 53 is formed in a tapered shape from the opening edge on the peripheral wall side of the loading opening 47 toward the inside of the battery chamber 12. In a state where the connection terminal 36 is inserted between the receiving ribs 53, the connection terminal 36 is clamped and fixed by the elastic force of the pair of receiving ribs 53.

  A stopper wall 55 that defines the insertion limit of the connection terminal 36 is formed at the inner back end of the receiving rib 53.

  An inner regulating wall 54 is formed at the protruding end of the receiving rib 53, and a pair of loading grooves 56 are formed by the dividing wall, the receiving rib 53 and the inner regulating wall 54.

  The fixed electrode lead 28 includes a main lead portion 34 disposed on the peripheral wall of the battery chamber 12, and a connection terminal 36 that is bent orthogonally to the main lead portion 34. The connection terminal 36 is formed wider than the main lead portion 34.

  The left-right width W1 of the loading opening 47 is set to be narrower than the width b2 of the main lead portion 34.

  A lead recess 42 that accommodates the main lead 34 is formed on the outer surface of the inner case 1 </ b> A facing the battery chamber 12.

  A fixing structure 45 for fixing the main lead portion 34 in an inseparable manner is integrally formed in the lead recess 42. As the fixing structure 45, a welding projection, a concave portion, a caulking projection, or the like can be applied.

  In the present invention, the loading opening 47 is formed from the bottom wall 46 to the peripheral wall of the battery chamber 12 of the inner case 1A, and the connection terminal 36 of the fixed electrode lead 28 can be inserted into the loading opening 47 from the outside. The connection terminal 36 can be assembled while being visually recognized through the loading opening 47. As described above, when the assembly state of the connection terminal 36 is made visible through the loading opening 47, whether the connection terminal 36 is assembled or not can be immediately determined visually. Therefore, it is possible to reliably and easily assemble the fixed electrode lead 28 with respect to the inner case 1A, and to reduce the labor and time of assembly.

  When the loading opening 47 is formed in the center of the left and right sides of the bottom wall 46 of the battery chamber 12 and the receiving rib 53 is provided on the inner surface of the dividing wall divided by the loading opening 47, the connection terminal 36 to be loaded in the loading opening 47. The right and left sides can be received and supported by the ribs 53. Therefore, even when the connection terminal 36 is obliquely loaded into the loading opening 47, the connection terminal 36 can be assembled while the posture of the connection terminal 36 is corrected to a correct posture. In the state where the assembly is completed, the left and right sides of the connection terminal 36 facing the battery chamber 12 are supported by the ribs 53, and the connection terminal 36 can be fixed and held without any wobble. Further, when the battery 5 is taken in and out, or when receiving a drop impact, the connection terminal 36 is displaced by the receiving rib 53 and is regulated by the rib 53, and the positional relationship between the battery 5 accommodated in the battery chamber 12 and the connection terminal 36. Can be made constant, and both can always be brought into contact in a stable state.

  When the facing surface of the receiving rib 53 is formed in a tapered shape from the opening edge on the peripheral wall side of the loading opening 47 toward the inside of the battery chamber 12, the connection terminal 36 is assembled in the loading opening 47. The both sides of the connection terminal 36 can be clamped and fixed by the elastic force of the left and right receiving ribs 53 that are elastically deformed. Therefore, the connection terminal 36 assembled to the loading opening 47 can be more firmly fixed and held, and the temporarily assembled fixed electrode terminal 28 can be reliably prevented from being separated from the inner case 1A.

  When the stopper wall 55 is formed at the inner back end of the receiving rib 53 and the insertion limit of the connection terminal 36 is defined by the stopper wall 55, the connection terminal 36 is prevented from being excessively inserted into the loading opening 47, and the connection terminal 36. The assembly posture can be made more appropriate. Further, in cooperation with the receiving rib 53, the position accuracy of the connecting terminal 36 assembled to the inner case 1A can be made stricter, and the conduction with the battery 5 can be performed in a more stable state.

  According to the structure in which the dividing wall, the receiving rib 53 and the inner regulating wall 54 form the loading groove 56 and the connecting terminal 36 is inserted into the groove 56 and engaged, the dividing wall, the receiving rib 53 and the inner regulating wall 54 are connected. By guiding the terminal 36, the assembly posture of the connection terminal 36 can be corrected to an appropriate state. Further, the connection terminal 36 assembled in the loading groove 56 is restricted from moving or deforming under external force, and can be electrically connected to the battery 5 in a stable state over a long period of time.

  If the fixed electrode lead 28 is constituted by the main lead portion 34 and the connection terminal 36 wider than this, it is sufficient to satisfy the electrical conduction function while forming the connection terminal 36 requiring mechanical strength wide. The width of the lead part 34 can be made as small as possible. Thereby, the waste of the structure of the fixed electrode lead 28 can be omitted, and the manufacturing cost can be reduced.

  When the left and right width W1 of the loading opening 47 is set to be narrower than the width b2 of the main lead portion 34, the main lead portion 34 is bent when it is bent toward the connection terminal 36 (see FIG. 1). The main lead portion 34 can be received by the dividing walls on both sides of the loading opening 47. According to this structure, the main lead portion 34 is restricted from protruding from the loading opening 47 by the dividing wall, and the assembly posture of the main lead portion 34 can be further optimized and positioned.

  When the lead concave portion 42 is formed on the outer surface of the inner case 1A facing the battery chamber 12 and the main lead portion 34 is accommodated in the lead concave portion 42, the main lead portion 28 is assembled in the state where the fixed electrode lead 28 is assembled to the outer surface of the inner case 1A. It can prevent that 34 protrudes from the surrounding surface of inner case 1A. Accordingly, the cross-sectional shape of the outer case 1B that is inserted into and removed from the inner case 1A can be simplified. Further, since the main lead portion 34 is positioned by the lead recess 42, the assembly posture of the fixed electrode lead 28 with respect to the inner case 1A can always be made appropriate.

  If the fixing structure 45 for fixing the main lead portion 34 in an inseparable manner is integrally formed in the lead recess 42, the fixing electrode lead 28 can be formed by simply deforming the fixing structure 45 by thermal deformation or mechanical caulking deformation. Easy to fix. In addition, considering the state in which the fixing structure 45 is thermally deformed or caulked, the depth of the lead recess 42 is set so that the deformed portion of the fixing structure 45 protrudes from the peripheral surface of the inner case 1A. Can be prevented.

  The main body case 1 is constituted by an inner case 1A including the head portion 2 and an outer case 1B which is inserted / removed into / from the inner case 1A and mainly forms a grip portion. As shown in FIG. 3 and FIG. 4, the inner case 1 </ b> A is configured by joining a front case 10 and a rear case 11 that are divided into front and rear portions in a lid-like manner. The front case 10 and the rear case 11 are each made of a plastic injection-molded product. A battery chamber 12 that accommodates the battery 5 is formed in the lower portion of the front case 10, and a motor chamber 13 that accommodates the motor 4, the drive mechanism, and the like is formed above the battery chamber 12. These chambers 12 and 13 are divided into upper and lower portions by a partition wall 14 provided on the inner surface of the front case 10. On the rear side of the battery chamber 12, an entrance / exit 15 for taking in / out the battery 5 is opened. The front blade unit 3 is detachably attached to the upper back surface of the inner case 1A, that is, the upper portion of the rear case 11.

  The outer case 1 </ b> B is formed of a cylindrical body having upper and lower ends that are formed of aluminum, and the lower end thereof is closed with an end cap 16. An escape groove 17 for exposing the operation knob 6 is formed on the upper peripheral surface of the outer case 1B. When the outer case 1B is completely inserted into the inner case 1A, the engagement structure provided between the two cases 1A and 1B is engaged to prevent the outer case 1B from being detached from the inner case 1A. Yes. When necessary, the battery 5 can be replaced by exposing the battery chamber 12 by removing the outer case 1B from the inner case 1A against the previous engagement structure.

  The blade unit 3 includes a case 20, a fixed blade 21 fixed to the case 20, a movable blade 22 reciprocally driven by a drive mechanism, and the like. In FIG. 4, the drive mechanism includes a driving gear 23 fixed to the output shaft of the motor 4, a face gear 24 that inherits the rotational power of the driving gear 23, and a drive that is reciprocated in the vertical direction by a crank pin 25 of the face gear 24. Arm 26. The distal end of the drive arm 26 is inserted and connected to a drive piece provided at the lower end of the previous movable blade 22. The face gear 24 is rotatably supported by a shaft 27 provided on the inner surface of the rear case 11 (see FIG. 4).

  The inner case 1A is provided with a switch structure for starting or stopping the motor 4 by switching the output state of the battery 5 between the on state and the off state. As shown in FIGS. 4 and 5, the switch structure is configured by using a fixed electrode lead 28, a negative connection terminal 29, a second switch terminal 30, and a switch piece 31 as conductive parts. These conductive parts are each formed of a stainless steel plate. The switch piece 31 is assembled to a slider 32 (see FIG. 4), and the switch piece 31 and the slider 32 are slid up and down with the switch knob 6 to bring the fixed electrode lead 28 and the second switch terminal 30 into a conductive state. It can be switched to the shut-off state. The slider 32 and the switch knob 6 are arranged on the inner and outer surfaces of the case with the switch window 33 (see FIG. 1) of the inner case 1A in between, and are slidably guided up and down. Although not shown, a moderation structure is provided between the slider 32 and the front case 10 to hold the switch knob 6 at the on / off positions.

  As shown in FIG. 1, the fixed electrode lead 28 is made of a press fitting formed by punching a stainless steel plate in a crank shape, and is arranged along the longitudinal direction (vertical direction) of the peripheral wall of the battery chamber 12. A first switch terminal 35 projecting laterally from the upper end of the main lead portion 34, and a positive-side connection terminal 36 that is bent rearward and orthogonally to the lower end of the main lead portion 34. The connection terminal 36 on the positive electrode side is bent so as to include a part of the main lead portion 34. On the plate surface of the main lead portion 34, five fastening holes 37 for engaging a welding projection 45 described later are formed. Further, elastically deformable claw pieces 38 for maintaining a temporarily assembled state are cut and raised at the left and right side edges of the positive connection terminal 36, and are formed below the terminal plate surface sandwiched between the both claw pieces 38. A contact protrusion 39 circumscribing the positive electrode of the battery 5 bulges out into a partial spherical shape. The width dimension b2 of the connection terminal 36 on the positive electrode side is set wider than the width dimension b1 of the main lead portion 34. The fixed electrode lead 28 may be formed of a sheet metal material other than a stainless steel plate material such as a copper plate or a plated steel plate.

  The connection terminal 29 on the negative electrode side is provided for conducting the negative electrode of the battery 5 and one input terminal 4 a of the motor 4, and is inserted into the partition wall 14. One end of the second switch terminal 30 is electrically connected to the other input terminal 4 b of the motor 4, and the contact portion of the other end is in a state of being spaced from the first switch terminal 35 of the fixed electrode lead 28. Adjacent to each other. The switch piece 31 is formed with a pair of left and right elastic arms 31a that are in contact with the first switch terminal 35 and the second switch terminal 30, and the first and second switch terminals 30 and 35 are formed by these elastic arms 31a. Turns on / off the continuity state. Similarly to the fixed electrode lead 28, the negative electrode side connection terminal 29, the second switch terminal 30, and the switch piece 31 are made of a press fitting formed by punching a stainless steel plate material.

  Specifically, as shown by a solid line in FIG. 5, when the elastic arm 31 a contacts the switch terminals 35, 30, the motor 4 can be started by bringing both switch terminals 30, 35 into a conductive state. Further, as shown by an imaginary line in FIG. 5, in a state where one of the elastic arms 31 a is separated from the first switch terminal 35, the motor 4 can be stopped by interrupting the conduction of both the switch terminals 30 and 35. Note that the positive-side connection terminal 36 and the negative-side connection terminal 29 function as reverse-polarity connection terminals when the loading orientation of the battery 5 into the battery chamber 12 is upside down.

  In order to assemble the fixed electrode lead 28, a lead recess 42 for accommodating the main lead portion 34 is formed in a crank shape on the front surface (outer surface) of the inner case 1 </ b> A facing the battery chamber 12, and is formed at the upper and lower ends of the lead recess 42. The terminal opening 43 and the loading opening 47 are formed. A round shaft-shaped welding projection (fixed structure) 45 corresponding to the previous fastening hole 37 is integrally formed in the lead recess 42. The terminal opening 43 communicates with the motor chamber 13, and the first switch terminal 35 is inserted into the motor chamber 13 through the terminal opening 43.

  The loading opening 47 is formed from the bottom wall 46 of the battery chamber 12 to the peripheral wall adjacent to the wall 46, and the positive-side connection terminal 36 is connected to the inside of the battery chamber 12 from the outer surface side of the peripheral wall through the loading opening 47. Can be plugged in and loaded. At this time, since the state where the connection terminal 36 is inserted into the battery chamber 12 can be directly recognized from the loading opening 47, the connection terminal 36 can be properly assembled. The loading opening 47 is linearly formed at the center of the left and right sides of the bottom wall 46 and divides the bottom wall 46 into the left and right. As shown in FIG. 6, the opening shape of the loading opening 47 on the peripheral wall side is a convex shape.

  In order to properly position the positive connection terminal 36 inserted into the battery chamber 12 from the terminal window 44 and firmly assemble it without wobbling, the receiving rib 53 and the dividing wall are provided on the inner surfaces of the left and right dividing walls. And an inner regulating wall 54 that is parallel to each other are formed in an inverted L shape. Furthermore, a stopper wall 55 that defines the insertion limit of the connection terminal 36 on the positive electrode side is formed at the inner back end of the receiving rib 53 and the inner regulating wall 54 (see FIG. 7).

  By providing the receiving rib 53 and the inner regulating wall 54 on the inner surface of the dividing wall, a pair of loading grooves 56 is formed by these three members. The left and right sides of the positive connection terminal 36 are inserted and engaged with these loading grooves 56. As shown in FIG. 6, the left-right width W1 of the opening edge on the bottom wall side of the loading opening 47 is set to be narrower than the width dimension b1 of the main lead portion 34, and the left-right width W2 of the opening edge on the peripheral wall side is positive. It is set equal to or slightly larger than the width dimension b1 of the connection terminal 36 on the side.

  As described above, when the loading opening 47 is formed from the bottom wall 46 to the peripheral wall, the receiving ribs 53 and the inner regulating walls 54 provided on the left and right dividing walls are shown by an imaginary line in FIG. Transforms into Therefore, the opposing surface of the receiving rib 53 is tapered toward the inside of the battery chamber 12. By using this tapered structure, the positive connection terminal 36 can be clamped and fixed between the left and right loading grooves 56 as will be described later.

  The fixed electrode lead 28 is assembled to the front case 10 as follows. As shown in FIGS. 1 and 7, after the front case 10 is placed on the work table with the doorway 15 facing downward, the first switch terminal 35 of the fixed electrode lead 28 is inserted into the terminal opening 43, and The positive-side connection terminal 36 is inserted from the outside of the peripheral wall through the loading opening 47, and the left and right sides of the connection terminal 36 are engaged with the left and right loading grooves 56. At the same time, the fastening hole 37 formed in the main lead portion 34 is engaged with the welding projection 45 provided in the lead recess 42. The connection terminal 36 can be assembled to the loading opening 47 from the outside on the bottom wall 46 side. For example, one side of the connection terminal 36 is inserted obliquely from the opening on the bottom wall 46 side of the loading opening 47, and the entire connection terminal 36 is assembled to the loading opening 47 while elastically deforming the other side. Alternatively, the connection terminal 36 that is flush with the main lead portion 34 is pushed in from the opening on the bottom wall 46 side of the loading opening 47 while being bent orthogonally. At this time, stepped claws are formed on the opposing surfaces of the left and right dividing walls, and the left and right edges of the connection terminal 36 are snapped into the claws, whereby the connection terminal 36 can be positioned and mounted in the loading opening 47. .

  In the process of engaging the left and right sides of the positive connection terminal 36 with the left and right loading grooves 56, the opposing surface of the receiving rib 53 is tapered toward the inside of the battery chamber 12. 36 is press-fitted between the opposing surfaces of the loading groove 56 while elastically deforming the left and right receiving ribs 53. At the same time, as shown in FIG. 8, both sides of the connection terminal 36 are inserted and engaged with the loading groove 56 while elastically deforming the claw piece 38. Therefore, in a state in which the connection terminal 36 is completely inserted and engaged with the loading groove 56, both side edges of the connection terminal 36 are supported by the receiving ribs 53 so that the connection terminal 36 can be fixed and held without any wobbling. . Similarly, the connecting terminal 36 can be prevented from coming off by the frictional force of the claw piece 38 that is pressed against the inner regulating wall 54 and elastically deformed. Therefore, the temporary assembly posture of the fixed electrode lead 28 can be maintained, and the main lead portion 34 can be reliably prevented from floating away from the lead recess 42 and the connection terminal 36 coming out of the loading opening 47.

  In the assembled state, the main lead portion 34 can be fixed to the front case 10 in an inseparable manner by melting and deforming the protruding end of the welding projection 45. In the process of inserting and engaging the connection terminal 36 on the positive electrode side in the loading groove 56, the assembled state of the connection terminal 36 can be visually recognized from the loading opening 47 on the bottom wall side. Therefore, it is possible to assemble the fixed electrode lead 28 while confirming whether the insertion start end of the connection terminal 36 is fully inserted into the loading groove 56 or whether the side edge is caught in the loading groove 56 and is not inclined. Can be done properly.

  The present invention can also be applied to a small electric device that does not include the motor 4, such as a heating-type eyelash shaping device that shapes an eyelash while applying heat. As shown in FIGS. 11 and 12, the eyelash shaping tool has a head part 2 for shaping at one end of the main body case 1, and first comb teeth 61 for shaping eyelashes on the left and right side surfaces of the head part 2. Second comb teeth 62 are provided, and heaters 63 and 64 for heating the eyelashes are arranged inside the respective comb teeth 61 and 62. The front-rear width of the first comb teeth 61 is set larger than the front-rear width of the second comb teeth 62, and the heater 63 for the first comb teeth 61 is larger than the heater 63 for the second comb teeth 62. The calorific value is set large. At the time of use, the eyelashes that grow mainly along the central portion of the eyelash line are curled by the first comb teeth 61, and the eyelashes that grow on the eye side and the eye corner side are curled by the second comb teeth 62. The second comb teeth 62 are also used when curling the lower eyelashes.

  As shown in FIG. 12, the heaters 63 and 64 for heating the eyelashes are replaced with the motor 4 in the previous embodiment, and the heater structure is used as it is by using a switch structure for turning on / off the energization state of the motor 4. The energization state to 63 and 64 can be turned on / off. The same members as those in the switch structure of FIG. The fixed electrode lead 28 in this embodiment can also be assembled to the front case 10 in the same manner as in the previous embodiment.

  FIG. 13 shows another embodiment in which the structure of the loading opening 47 in the front case 10 is changed. In this case, the right half of the bottom wall 46 of the front case 10 and the right half of the peripheral wall facing the terminal window 44 are omitted to form a loading opening 47. On the inner surface of the left half of the bottom wall 46, a receiving rib 53, an inner regulating wall 54, a stopper wall 55 and the like similar to those of the previous embodiment are formed. Since others are the same as the previous embodiment, the same members are denoted by the same reference numerals and description thereof is omitted. The same applies to the following embodiments.

  As described above, when the loading opening 47 is wide, it can be inserted into the terminal window 44 with most of the positive-side connection terminal 36 exposed, so the connection terminal 36 is inserted into the loading groove 56. Throughout the loading opening 47, the entire process of the combination can be clearly seen. Further, one side of the connection terminal 36 can be assembled while being inserted laterally into the loading groove 56.

  14 and 15 show another embodiment of the switch structure. There, the connection terminal 66 provided at the upper end of the fixed electrode terminal 28 was connected to one input terminal 4 b of the motor 4, and one end of the second switch terminal 30 was connected to the other input terminal 4 a of the motor 4. Further, a U-shaped switch piece 31 is sandwiched between the connection terminal 29 on the negative electrode side and the second switch terminal 30, and the motor 4 is turned on / off by rotating the switch piece 31 with the dial (operation tool) 6. I was able to do it. The first switch terminal 35 in this case is provided on the connection terminal 29 on the negative electrode side. FIG. 15 shows a state in which the first switch terminal 35 and the second switch terminal 30 of the connection terminal 29 are electrically connected via the switch piece 31. From this state, the dial 6 is rotated 90 degrees to the left or right. By doing so, the electrical connection state of the 1st switch terminal 35 and the 2nd switch terminal 30 can be interrupted | blocked. As can be understood from this embodiment, the operation tool 6 does not have to be a slide switch, but may be a rotation changeover switch, a push button switch, or a tilt changeover switch.

  FIG. 16 shows still another embodiment of the switch structure. In this case, similarly to the switch structure of FIG. 14, the connection terminal 66 provided at the upper end of the fixed electrode terminal 28 is connected to one input terminal 4 b of the motor 4, and the other input terminal 4 a is used as the second switch terminal 30. did. Further, a first switch terminal 35 that can be elastically deformed is integrally provided on one side of the connection terminal 29 on the negative electrode side, and the first switch terminal 35 is directly contacted / separated by the switch knob 6, so Can be turned on and off. The first switch terminal 35 in this case also serves as the switch piece 31, and a protrusion 6 a for pressing the switch piece 31 is integrally provided on the inner surface of the switch knob 6 that slides up and down. As can be understood from the above switch structure, the first switch terminal 35 and the second switch terminal 30 are arranged at arbitrary positions of a conduction circuit that connects the load such as the motor 4 and the heaters 63 and 64 and the battery 5. And can be freely arranged according to differences in the structure and arrangement structure of the operation tool 6.

  The small electric devices such as the face shaver and the eyelash shaping device described in the above embodiment are housed in a blister pack and are displayed in a state of being hooked on a display hook. In the conventional blister pack, the blister case and the mount are fixed so that they cannot move relative to each other in order to prevent the mount from sliding open during display or handling. For example, the adhesive tape is attached to an adjacent portion of the blister case and the mount, or the overlapped portion of the blister case and the mount is bound with a stapler to prevent the mount from moving. However, in any case, it is necessary to peel the adhesive tape or remove the binding needle to take out the object to be stored in the blister case, which is troublesome. In addition, when the storage object taken out from the blister pack and used is stored using the blister pack, the mount must be fixed again, which requires extra work.

  In order to reduce the troublesome work described above, a round cylindrical suspension hole is integrally formed in the center of the left and right sides of the blister case, and the round hole provided on the mount is the cylinder of the previous suspension hole. There is a blister pack (Japanese Patent Laid-Open No. 11-29137) that engages with a wall to regulate the opening movement of the mount. In this case, when the mount is inserted into the blister case, a part of the guide wall is inserted into the notch formed in the mount so that the guide wall can be prevented from floating. It helps to regulate.

  However, in the above blister pack, since the length of the cylindrical wall having the suspension hole is only about the thickness of the double-folded mount, the mount may be detached from the cylindrical wall, and the mount cannot be fixed in a stable state. . In addition, when inserting a part of the guide wall into the notch of the mount, the paper surface of the cut end may be broken, and there is room for improvement in that the mount cannot be accurately fixed by the blister case as a whole. .

  The blister pack shown in FIG. 17 to FIG. 20 solves the above-described problems, and enables the mount to be accurately fixed by the blister case. In addition, when storing an object to be stored using a blister pack, the mount can be securely restricted with a blister case, or when necessary, the release restriction state can be canceled with a simple operation to easily put in and out the mount. It is what I did.

  The blister pack in FIG. 17 is configured as a slide type blister pack with a vertically long (rectangular) blister case 71 and a vertically long (rectangular) mount 72 inserted and loaded into the blister case 71. The blister case 71 can be formed of a transparent plastic material such as PET resin, PS resin, or PVC resin.

  On the main surface wall of the blister case 71, for example, a main body housing portion 73 for housing a face shaver and an accessory housing portion 74 are formed in a state of bulging outward. Receiving walls 75 are bent on both the left and right sides and the lower side of the back surface of the blister case 71, and the back surface side of the blister case 71 is opened and closed by sliding the mount 72 with these receiving walls 75. Face shaver and accessories can be taken in and out. Reference numeral 76 denotes a hanging hole that is hooked to the display hook.

  In order to accurately fix the mount 72 by the blister case 71, the hooking tongue piece 81 is formed in a projecting manner near the upper ends of the opposing edges of the left and right receiving walls 75. In addition, a hooking hole 82 corresponding to the hooking tongue piece 81 is formed in the mount 72, and the hooking tongue piece 81 is inserted into and engaged with the hooking hole 82, whereby the mount 72 is moved in the opening direction. The latching tongue piece 81 can be regulated.

  As shown in FIG. 18, the mount 72 is composed of a front paper surface 72A and a rear paper surface 72B that are continuous via a linear bent portion 77, and vertical latch holes 82 are formed on the upper left and right of the rear paper surface 72B. It is formed. On the surface of the front paper surface 72A and the rear paper surface 72B, product names, manufacturer names, usage examples of products stored in blister packs, barcodes, and the like are printed. The front sheet surface 72A and the rear sheet surface 72B are folded in two with the folding portion 77 as the center, and the mounting sheet 72 is inserted with the attached document 83 such as an instruction manual, a warranty card, and a postcard sheet sandwiched between the two sheet surfaces 72A and 72B. The blister case 71 is loaded. The mount 72 at this time is inserted and loaded into the blister case 71 from above with the bent portion 77 side as the upper end.

  As described above, the mount 72 in the state of being loaded in the blister case 71 has its left and right side edges and lower edge received by the receiving wall 75 and positioned. In this state, the latching tongue piece 81 is inserted into and engaged with the latching hole 82, and the mount 72 is fixed by the blister case 71 so as not to move freely. Finally, punching is performed to form the suspension holes 76 in the blister case 71 and the mount 72 at the same time. The attached document 83 arranged between the front paper surface 72A and the rear paper surface 72B is preferably folded so that the vertical dimension is smaller than the length from the lower end of the mount 72 to the lower end of the retaining hole 82. . The attached document 83 folded in this way can be restricted from moving upward by receiving the upper edge thereof with the latching tongue piece 81.

  The detailed structure of the latching tongue piece 81 and the latching hole 82 is shown in FIGS. The hooking tongue piece 81 is formed in a tapered shape including a lower edge 85 orthogonal to the vertical hooking hole 82 and an upper edge 86 inclined downward toward the tip of the tongue piece. Both corners of the base end and both corners of the overhanging tip are rounded. The retaining hole 82 is formed as a vertically elongated rectangular hole with rounded corners, and the vertical length of the retaining hole 82 is slightly larger than the vertical width k2 of the retaining tongue piece 81 to be described later. It is set.

  As described above, when the lower edge 85 of the latching tongue piece 81 is horizontal and the upper edge 86 is inclined in a tapered shape, the latching tongue piece 81 can be easily inserted into and removed from the latching hole 82. Further, when the mount 72 moves upward, the lower end 85 of the retaining hole 82 is received by the lower edge 85, so that the mount 72 can be prevented from coming off. Further, as shown in FIG. 19, the latching tongue piece 81 is inserted into the inner surface of the rear paper surface 72B in a state of obliquely crossing the interior of the latching hole 82. Can be prevented from acting on a part of the retaining hole 82, and the lower end of the retaining hole 82 can be prevented from being deformed or torn.

  When the protruding length of the hooking tongue piece 81 is k1 and the vertical width of the hooking tongue piece 81 is k2, the protruding length k1 is set sufficiently larger than the vertical width k2. In other words, the hooking tongue piece 81 is formed in a horizontally long belt shape so that the whole can be deformed smoothly. Thus, when the latching tongue piece 81 is formed in a horizontally long strip shape, when the latching tongue piece 81 is engaged with the latching hole 82 or removed from the latching hole 82, the latching tongue piece 81 is used. Since 81 can be taken in and out while being largely curved, the attaching / detaching operation of the latching tongue piece 81 can be performed more easily.

  When the latching distance from the projecting protruding end of the latching tongue piece 81 to the latching hole 82 is L1, and the adjacent distance from the projecting proximal end of the latching tongue piece 81 to the latching hole 82 is L2, the latching distance L1. Is set sufficiently larger than the adjacent distance L2. According to this structure, in a state where the latching tongue piece 81 is engaged with the latching hole 82, most of the latching tongue piece 81 can be sandwiched between the front paper surface 72A and the rear paper surface 72B of the mount 72. It is possible to prevent the tongue piece 81 from coming out of the retaining hole 82 well. In addition, by securing the adjacent distance L2, when the latching tongue piece 81 is removed from the latching hole 82, the fingertip is hooked on the projecting proximal end of the latching tongue piece 81 to bend the latching tongue piece 81. It can be reliably extracted.

  When the protruding length of the retaining tongue piece 81 from the inner edge of the receiving wall 75 is L3, and the left and right width of the receiving wall 75 on which the retaining tongue piece 81 is formed is L4, the protruding length L3 is the left and right width L4. Set it sufficiently larger. According to this structure, by greatly curving the entire hooking tongue piece 81, the protruding tip of the hooking tongue piece 81 can be easily engaged with the hooking hole 82, and further, the hooking force can be locked by a restoring force due to its own elasticity. The tongue piece 81 can be slid between the front paper surface 72A and the rear paper surface 72B. Further, since the overhang length L3 is sufficiently larger than the left and right width L4, for example, even when the receiving wall 75 is forcibly erected from the mount 72, the hooking tongue piece 81 comes out of the hooking hole 82. The engagement state can be maintained by restricting the above. However, as described above, as long as the latching tongue piece 81 is operated in an appropriate procedure, the latching tongue piece 81 can be attached to and detached from the latching hole 82 without any trouble.

  According to the blister pack configured as described above, after the mount 72 is inserted into the back surface of the blister case 71, the mount 72 is removed from the blister case 71 simply by inserting the engaging tongue piece 81 into the engaging hole 82 and engaging. It can be surely prevented from coming out. Therefore, the mount 72 can be fixed by the blister case 71 accurately and with a simple structure. Further, even when the object to be stored is stored using a blister pack, the mounting tongue 72 can be inserted into and engaged with the locking hole 82 and the mount 72 can be reliably restricted from being opened. When necessary, the mount 72 can be removed by a simple operation of simply removing the retaining tongue 81 from the retaining hole 82. Therefore, peeling of the adhesive tape, which is inevitable when taking out the object to be stored from the blister pack, and binding Troublesome troubles such as needle removal can be eliminated.
