Thereby, as shown in FIGS. 9 and 10, the second guide section 37 connects the support frame 33 and the waterproof packing guided to the gap S between the locking piece 31 and the inner wall surface 30 in the battery storage section 10. 34 into the gap S between the inner wall surface 30 of the battery storage section 10 and the plurality of locking pieces, and the elastic protrusion 34a of the waterproof packing 34 is pressed against the inner wall surface 30 of the battery storage section 10 to cause elastic deformation. This state is maintained so that the engaging protrusion 33a is engaged with the locking hole 31a.

In this case, as shown in FIGS. 9 and 10, the plurality of locking pieces 31 and the elastic protrusions 34a, In addition, the plurality of locking pieces 31 are elastically returned to their original shapes, and the elastic protrusions 34a are slightly elastically returned to their stable shapes.

In addition, as shown in FIGS. 9 and 10, the engagement protrusion 33a of the support frame 33 bites into the engagement hole 31a of the engagement piece 31 and is inclined toward the inner surface of the engagement hole 31a. A drawing inclined surface 33b to be pressed is provided. The drawing inclined surface 33b is inclined with a draft angle θ from the end portion on the biting side of the engagement protrusion 33a toward the opening 10a side of the battery storage portion 10. That is, the draft angle θ of the draft inclined surface 33b is set according to the bending deformation force of the locking piece 31 in the direction toward and away from the inner wall surface 30 of the battery storage portion 10.

As a result, as shown in FIGS. 9 and 10, the battery lid 8 is configured such that the support frame 33 of the lid main body 32 is connected to the inner wall surface 30 of the battery storage portion 10 in a state where the opening 10a of the battery storage portion 10 is closed. When the locking piece 31 is pulled out from between the locking piece 31, the inner surface of the locking hole 31a of the locking piece 31 slides relatively along the extraction slope 33b of the locking protrusion 33a, so that the locking piece 31 The engaging protrusion 33a is configured to easily come out from the locking hole 31a.

In this case, the edge of the locking hole 31a of the locking piece 31, that is, the edge of the inner surface of the locking hole 31a where the extraction inclined surface 33b of the engagement protrusion 33a is locked, is shown in FIGS. 9 and 10. As shown, an arc-shaped chamfered portion 31b is provided which relatively slides along the drafting inclined surface 33b. The arcuate chamfered portion 31b is configured to allow the battery cover 8 to slide down relatively easily along the extraction slope 33b of the engagement protrusion 33a when the battery cover 8 is removed from the battery storage portion 10.

Furthermore, as shown in FIGS. 3 to 5, the plurality of sets of locking pieces 31, that is, the plurality of sets of locking pieces 31 arranged along the longitudinal direction of the device case 1 and facing each other, are arranged in pairs of locking pieces 31 facing each other, as shown in FIGS. The opposing interval of the locking pieces 31 corresponds to one end of the lid body 32 when the battery lid 8 rotates the lid body 32 using the other end 8d of the lid body 32 as a fulcrum to close the opening 10a of the battery storage section 10. It is set so that it becomes gradually narrower from the portion 8c side toward the other end portion 8d.

That is, as shown in FIGS. 4, 5, and 9, the amount of biting of the plurality of engagement protrusions 33a into each of the locking holes 31a of the plurality of locking pieces 31 is determined from one end 8c of the battery lid 8 to the other end. It is set so that the number gradually increases toward the portion 8d side. As a result, when the battery cover 8 is rotated about the other end 8d and removed from the battery storage section 10, the engagement force of the engagement protrusion 33a with respect to the locking hole 31a on the one end 8c side of the battery cover 8 is reduced. The engagement force of the engagement protrusion 33a with respect to the locking hole 31a gradually increases from the one end 8c side of the battery lid 8 toward the other end 8d side.

Therefore, as shown in FIGS. 4, 5, and 9, when the battery lid 8 is rotated about the other end 8d and removed from the battery housing 10, the battery lid 8 is Since the engagement force of the engagement protrusion 33a with the locking hole 31a is weak, the structure is such that the engagement of the engagement protrusion 33a with the locking hole 31a on the one end 8c side of the battery cover 8 can be easily released.

Further, as shown in FIGS. 4, 5, and 9, when the battery lid 8 is rotated about the other end 8d and removed from the battery housing 10, the battery lid 8 is removed from the one end 8c side. Even if the engagement force of the engagement protrusion 33a with respect to the locking hole 31a becomes stronger toward the other end 8d and it is difficult to remove, the battery cover 8 rotates and stands up using the other end 8d as a fulcrum. The engagement protrusion 33a is configured to become easier to disengage from the locking hole 31a as it goes from the one end 8c side to the other end 8d side of the locking hole 31a.

In this case, as shown in FIGS. 2 and 4 to 6, on both sides of the device case 1 in the lateral direction located on the one end 8c side of the battery lid 8, there are Finger hook notches 38 are provided on both sides in the direction to make it easier to hook fingers. As a result, when removing the battery cover 8 from the battery storage section 10, the finger of the hand is hooked onto the finger hook notch 38, and the battery cover 8 is rotated using the other end 8d of the battery cover 8 as a fulcrum. It is configured so that it can be easily removed from the battery storage section 10.

Next, the operation of this mobile terminal will be explained.
First, the battery cover 8 is removed from the device case 1 and the battery pack 13 is stored in the battery storage section 10. In this case, the lever portion 11b of the lock lever 11 is swung within the lever storage recess 3a to rotate the lock portion 11a, thereby unlocking the one end portion 8c of the battery cover 8 by the lock portion 11a.

In this state, hook your fingers into the notches 38 provided on both sides of the device case 1 corresponding to the one end 8c of the battery lid 8, and insert the one end 8c side of the battery lid 8 into the battery compartment 10. pull it up from Then, one end 8c of the battery cover 8 is rotated upward about the other end 8d and removed from the battery storage section 10, and the battery storage section 10 is opened.

In this state, the battery pack 13 is stored in the battery storage section 10. At this time, the battery terminal section 22 protrudingly provided at one end 13a of the battery pack 13 is directed toward the power terminal section 18 provided at one side inside the battery storage section 10 located at the one end 1a of the device case 1. Then, as shown in FIG. 11(a), the battery pack 13 is tilted and inserted into the battery storage section 10.

Then, the arc-shaped chamfered portion 23c of the first side wall portion 23a of the first protection guide portion 23 of the battery pack 13 comes into contact with the bottom inside the battery storage portion 10, and in this state, the battery pack 13 is turned toward the power terminal portion 18. and slide it. Then, the chamfered portion 23c of the first protection guide portion 23 slides while being gradually ridden by the guide slope portion 25 of the pedestal portion 20 of the power terminal portion 18.

At this time, the battery pack 13 is rotated so that the inclination of the battery pack 13 is gradually reduced by the arc-shaped chamfered part 23c of the first side wall part 23a, and the battery terminal part 22 approaches the power supply terminal part 18 so as to intersect with it. . Then, when the arc-shaped chamfered portion 23c of the first side wall portion 23a runs over the guide slope portion 25, the first protective guide portion 23 of the battery pack 13 is guided by the second protective guide portion 24 in the battery storage portion 10. , the battery terminal section 22 is connected to the power supply terminal section 18 in a substantially orthogonal state.

That is, when the first protection guide part 23 of the battery pack 13 is guided by the second protection guide part 24 in the battery storage part 10, the first side wall part 23a of the first protection guide part 23 is guided by the second protection guide part 24. It is guided by the second side wall part 24a of the section 24, and the opposing surface of the first side wall part 23a is guided by both side surfaces of the guide support part 20a of the pedestal part 20. Thereby, the first protection guide part 23 is protected by covering the first side wall part 23a with the second side wall part 24a of the second protection guide part 24, and the first roof part 23b is protected by the second protection guide part 24a. It is covered and protected by the second roof part 24b.

When the first protective guide part 23 of the battery pack 13 is guided by the second protective guide part 24 in the battery storage part 10 in this way, each clamping terminal 22a of the battery terminal part 22 of the battery pack 13 is connected to the power supply terminal. Each standing terminal 18a of the portion 18 is sandwiched and contacted to be connected to each standing terminal 18a. Thereby, the battery pack 13 is stored in the battery storage section 10.

That is, when the battery terminal part 22 is connected to the power supply terminal part 18 substantially perpendicularly, the pedestal part 20 is placed in the set recess 23d provided on the surface of the battery pack 13 opposite to the first roof part 23b. Placed. As a result, the battery pack 13 is stored in the battery storage section 10 with the lower surface, which is one surface, of the battery pack 13 being in close contact with the bottom of the battery storage section 10 .

Then, the battery storage section 10 is covered with the battery lid 8. At this time, the other end 8d of the battery lid 8 is locked to the end of the opening 10a of the battery storage section 10 located on the other end 1b side of the device case 1, and the other end 8d of the battery lid 8 that is locked is The battery cover 8 is rotated using the end 8d as a fulcrum, and the one end 8c of the battery cover 8 is brought close to the end of the opening 10a of the battery storage section 10 located on the one end 1a side of the device case 1.

Then, the support frame 33 of the battery lid 8 is sequentially pushed between the inner wall surface 30 and the plurality of sets of locking pieces 31 provided on the inner wall surface 30 in the battery storage section 10 . That is, the plurality of sets of locking pieces 31 are arranged along the longitudinal direction of the device case 1 and provided on the inner wall surfaces 30 of the battery storage section 10 that face each other. . In this case, the plurality of sets of locking pieces 31 are set such that the distance between the opposing pairs of locking pieces 31 gradually narrows from the one end 8c side of the lid main body 32 toward the other end 8d. There is.

Further, in these plurality of sets of locking pieces 31, the amount of biting of each of the plurality of engagement protrusions 33a into each locking hole 31a of the plurality of locking pieces 31 is from one end 8c of the battery lid 8 to the other end 8d. The number gradually increases towards . Therefore, when the battery cover 8 rotates about the other end 8d to attach the battery compartment 10, the engagement force of the engagement protrusion 33a with respect to the locking hole 31a on the other end 8d side of the battery cover 8 is strong, and the engagement force of the engagement protrusion 33a with respect to the locking hole 31a gradually becomes weaker as it goes from the other end 8d side to the one end 8c side of the battery cover 8.

Therefore, when the battery cover 8 rotates about the other end 8d and is attached to the battery storage section 10, the battery cover 8 is rotated from the one end 8c side to the other end 8d side. The pushing force gradually increases. As a result, the support frame 33 of the battery cover 8 is successively pushed between the inner wall surface 30 in the battery storage section 10 and the plurality of locking pieces 31, and is securely attached. At this time, the support frame 33 of the battery lid 8 is well pushed together with the waterproof packing 34 between the inner wall surface 30 in the battery storage section 10 and the plurality of locking pieces 31 by the guide lock section 35 .

That is, the first guide portion 36 of the guide lock portion 35 connects the second guide inclined surface 36b of the support frame 33 with the first guide of the locking piece 31 when closing the opening 10a of the battery storage portion 10 with the battery lid 8. The engaging protrusion 33a of the support frame 33 and the waterproof packing 34 are connected to the inner wall surface 30 of the battery storage section 10 and the locking piece 31 by sliding it along the first guide inclined surface 36a while in contact with the inclined surface 36a. The locking piece 31 is guided smoothly and well into the gap S between them while being bent.

In this state, when the support frame 33 is further pushed between the inner wall surface 30 of the battery storage section 10 and the locking piece 31, the second guide insertion surface 37b provided on the engagement protrusion 33a of the support frame 33 is engaged. Since it is guided along the first guide insertion surface 37a of the second guide part 37 provided on the stopper piece 31, the elastic protrusion 34a of the waterproof packing 34 is pressed against the inner wall surface 30 of the battery storage part 10 and is elastically deformed. By maintaining this state, the support frame 33 is smoothly and reliably pushed between the inner wall surface 30 of the battery storage section 10 and the locking piece 31, and the engaging protrusion 33a is securely inserted into the locking hole 31a. And it engages well.

In this way, when the engagement protrusion 33a engages with the locking hole 31a, the plurality of locking pieces 31 return to their original states, and the elastic protrusion 34a slightly elastically returns to a stable shape. Therefore, the elastic protrusion 34a is pressed against the inner wall surface 30 of the battery storage portion 10 in a stable shape reliably and well. Thereby, the waterproofing of the battery storage part 10 can be achieved reliably and satisfactorily.

In this state, one end 8c of the battery cover 8 is locked by the lock lever 11. That is, the lever part 11b of the lock lever 11 is swung within the lever storage recess 3a to rotate the lock part 11a, and the one end part 8c of the battery cover 8 is locked by the rotated lock part 11a. Thereby, the battery cover 8 is reliably and favorably attached to the battery storage section 10.

Next, a case where a user holds and uses such a mobile terminal will be described.
In this case, the fingers other than the thumb of the hand are placed on the back side of the device case 1, and the thumb is placed on the input display section 4 or the key input section 5 of the device case 1. Grasp the battery cover 8 so as to wrap it around it.

In this state, input operation is performed on the input display section 4 or the key input section 5 with the thumb. At this time, since the information displayed on the display panel 4a of the input display section 4 can be seen through the transparent touch panel 4b, the user can touch-operate the transparent touch panel 4b while viewing the information displayed on the display panel 4a.

In this state, when either the top trigger key 5a of the key input section 5 or the side trigger key 1c provided on the side surface of the device case 1 is operated, the scanner section 9b of the optical reading section 9 is driven. Ru. Then, the laser reading section of the scanner section 9b irradiates the product code of the product with a laser beam through the optical window section 7c of the storage convex section 7, receives the reflected light, and reads the product code.

Also, at this time, the camera section of the scanner section 9b photographs objects such as products, articles, two-dimensional codes, and the like. As a result, the product code read by the laser reading section is displayed on the input display section 4 and registered in the memory section of the circuit board 6. Similarly, objects such as products, articles, and two-dimensional codes photographed by the camera section are displayed on the input display section 4 and are also registered in the memory section of the circuit board 6.

When such a mobile terminal is dropped from a tabletop or from a hand, the device case 1 receives a shock from the fall. At this time, the plurality of sets of engagement protrusions 33a provided on the support frame 33 of the battery lid 8 are locked into the respective locking holes 31a of the plurality of sets of locking pieces 31 provided on the inner wall surface 30 of the battery storage section 10. Therefore, deformation of the battery cover 8 due to impact caused by dropping can be suppressed. Therefore, the battery cover 8 will not come off from the battery storage section 10 due to impact, so the battery pack 13 stored in the battery storage section 10 will not fall off.

Next, a case will be described in which the battery cover 8 is removed from the battery storage section 10 and the battery pack 13 is replaced.
In this case, as described above, operate the lock lever 11 to unlock the one end 8c of the battery cover 8 by the lock part 11a, and in this state, open the device case 1 corresponding to the one end 8c of the battery cover 8. One end 8c side of the battery cover 8 is pulled up from the battery storage section 10 by hooking one's fingers on the notches 38 for finger hooks provided on both sides.

Then, the battery cover 8 rotates with one end 8c facing upward using the other end 8d as a fulcrum. At this time, the distance between the opposing pairs of locking pieces 31 in the plurality of sets of locking pieces 31 is set so as to gradually become narrower from the one end 8c side to the other end 8d of the lid main body 32. The amount of biting of each of the plurality of engagement protrusions 33a into each of the locking holes 31a of the locking piece 31 gradually increases from one end 8c of the battery cover 8 toward the other end 8d.

Therefore, when the battery cover 8 is rotated about the other end 8d and removed from the battery storage section 10, the engagement force of the engagement protrusion 33a with respect to the locking hole 31a on the one end 8c side of the battery cover 8 is The engagement force of the engagement protrusion 33a with respect to the locking hole 31a gradually increases from the one end 8c side of the battery cover 8 toward the other end 8d side. Therefore, when the battery cover 8 is gradually tilted in the direction of standing up with respect to the battery storage part 10, the initial lifting force is light, so the battery cover 8 can be easily rotated, and each of the plurality of locking pieces 31 can be rotated. The engagement of the plurality of engagement protrusions 33a with the locking hole 31a is sequentially released.

In this way, when the battery cover 8 rotates about the other end 8d to remove the battery compartment 10, the battery cover 8 is rotated from the one end 8c side to the other end 8d side. 8 support frames 33 are successively removed from between the inner wall surface 30 and the plurality of locking pieces 31 in the battery storage section 10. At this time, the engaging protrusion 33a of the support frame 33 easily comes out of the locking hole 31a of the locking piece 31 due to the extraction inclined surface 33b.

That is, the draft slope 33b has a draft angle θ set according to the bending deformation force of the locking piece 31 in the direction toward and away from the inner wall surface 30 of the battery storage portion 10. For this reason, when the support frame 33 of the lid main body 32 is pulled out from between the inner wall surface 30 of the battery storage part 10 and the plurality of locking pieces 31 with the battery lid 8 blocking the opening 10a of the battery storage part 10, In this case, the inner surface of the locking hole 31a of the locking piece 31 relatively slides along the extraction slope 33b of the engagement protrusion 33a. As a result, the engaging protrusion 33a easily comes out of the locking hole 31a of the locking piece 31.

At this time, an arcuate chamfered portion 31b is provided at the edge of the locking hole 31a of the locking piece 31, that is, at the edge of the inner surface of the locking hole 31a where the extraction inclined surface 33b of the engagement protrusion 33a is locked. slides relatively along the extraction inclined surface 33b. In this case, the locking piece 31 is bent and deformed in a direction away from the inner wall surface 30, and the elastic protrusion 34a of the waterproof packing 34 is pressed against the inner wall surface 30 and elastically deformed.

Therefore, when the battery cover 8 is removed from the battery storage section 10, the arc-shaped chamfered portion 31b relatively slides down along the extraction slope 33b of the engagement protrusion 33a, and the engagement protrusion 33a becomes the locking piece. 31 from the locking hole 31a. As a result, the engaging protrusion 33a can be easily and efficiently removed from the locking hole 31a of the locking piece 31.

In this way, when the battery cover 8 is removed from the battery storage section 10, the battery pack 13 inside the battery storage section 10 is exposed. When taking out the battery pack 13 from inside the battery storage section 10, the other end 13b of the battery pack 13 located on the other end 1b side of the device case 1 is pulled up from inside the battery storage section 10.

Then, the battery pack 13 gradually tilts while rotating obliquely upward about the arc-shaped chamfered part 23c of the first protection guide 23 provided at one end 13a of the battery pack 13, and the other parts of the device case 1 Slide toward the end 1b side. Thereby, the battery pack 13 can be taken out from inside the battery storage section 10. In this state, the battery pack 13 can be replaced.

Furthermore, when the battery pack 13 is taken out from the battery storage section 10, the cards 29, such as SIM cards (communication cards) and memory cards, installed in the first card mounting section 26 and the second card mounting section 27 are replaced. can do. That is, the card 29 mounted in the first card mounting part 26 and the second card mounting part 27 is moved between the first card mounting part 26 and the second card mounting part 27 by operating a release lever (not shown) or pushing the card 29. The card is taken out from the card mounting section 27 into the battery storage section 10.

Then, a new card 29 is inserted into the first card mounting section 26 and the second card mounting section 27 from inside the battery storage section 10. When replacing the card 29 in this way, since the inside of the battery compartment 10 is much wider than the card 29, insert the card 29 into the first card mounting part 26 and the second card from the inside of the battery compartment 10. The operation of inserting and removing the card 29 into and out of the mounting part 27 is quick, and the card 29 can be replaced easily.

In this case, the power terminal section 18 is provided between the first card mounting section 26 and the second card mounting section 27, and the battery terminal section 22 of the battery pack 13 is provided to protrude from one end 13a of the battery pack 13. By doing so, the battery terminal section 22 of the battery pack 13 can be well connected to the power terminal section 18 in the battery storage section 10 without the first card mounting section 26 and the second card mounting section 27 getting in the way. I can do it.

Further, the first card mounting section 26 and the second card mounting section 27 are located on both sides of the power terminal section 18 in the device case 1 corresponding to the base of the second inclined surface 7b in the storage convex section 7 of the device case 1. By being arranged side by side along the lateral direction of the device case 1, the first card mounting section 26 and the second card mounting section 27 can be installed compactly within the device case 1. Therefore, the packaging density within the device case 1 is increased, and the insertion and removal of the card 29 into and from the first card mounting section 26 and the second card mounting section 27 is ensured by utilizing the inside of the battery storage section 10. .

As described above, according to this mobile terminal, the battery storage section 10 has one end side of the power terminal section 18 which is the first terminal section, and the second terminal section electrically connected to the power terminal section 18. A battery pack 13 which is a battery module is formed such that a battery terminal part 22 which is a terminal part protrudes toward the power terminal part 18 side.

In addition to being able to protect the protective guide section 23, since the clamping terminal 22a of the battery terminal section 22 clamps the standing terminal 18a of the power supply terminal section 18, it is possible to prevent connection failure due to impact and improve connection reliability. can be secured.

In this case, in this mobile terminal, the second protection guide part 24, which is the first protection part, has the second roof part 24b, which is the first roof part, provided so as to cover the tip side of the standing terminal 18a. However, the first protection guide part 23, which is the second protection part, is a second roof part provided so as to face the second roof part 24b when the battery pack 13 is stored in the battery storage part 10. By having a certain first roof part 23b, the first roof part 23b can be covered and protected by the second roof part 24b, and the first roof part 23b and the second roof part 24b can provide power supply. The standing terminal 18a of the terminal portion 18 and the clamping terminal 22a of the battery terminal portion 22 can be well protected.

In addition, in this mobile terminal, the first protection guide section 23 includes a first side wall section 23a that protects both sides of the battery terminal sections 22 in the arrangement direction, and a first side wall section 23a that protects both sides of the battery terminal sections 22 in the arrangement direction.

Further, in this mobile terminal, the power supply terminal section 18 has a guide support section 20a that is a part of the pedestal section 20 that supports the upright terminal 18a, and the pair of first side wall sections 23a have a guide support section 20a that is a part of the base section 20 that supports the upright terminal 18a. When the battery terminal section 22 is connected to the power supply terminal section 18, the guide support sections 20a of the pedestal section 20 are formed so that they can be fitted into each other when the battery terminal section 22 is housed in the power source terminal section 10. Since the facing surface of the side wall portion 23a can be guided by both side surfaces of the guide support portion 20a of the pedestal portion 20, the battery terminal portion 22 can be connected to the power terminal portion 18 accurately and well.

Further, in this mobile terminal, the second protective guide section 24 has a predetermined opening, that is, an open section where the second side wall section 24a and the second roof section 24b are opened, and the battery pack 13 has a predetermined opening section where the second side wall section 24a and the second roof section 24b are opened.
