[Modes for carrying out the invention]
[0010] Hereinafter, an embodiment of a mobile terminal to which this invention is applied will be described with reference to Figures 1 to 11. As shown in Figures 1 and 2, this portable terminal is an information terminal such as a handheld terminal for processing information, and is equipped with a device case 1. This device case 1 consists of an upper case 2 on the front side and a lower case 3 on the back side, and the whole is formed in the shape of a nearly rectangular box with a thin profile.
[0011] As shown in Figure 1, an input display unit 4 and a key input unit 5 are provided in parallel on the surface of the device case 1, that is, the upper surface of the upper case 2. The input display unit 4 is provided on the upper surface of the upper case 2, covering a wide area of approximately 3 / 4 of the longitudinal direction of the device case 1, from one end 1a to the other end 1b. The key input unit 5 is provided in the area excluding the input display unit 4, that is, in a narrow area of approximately 1 / 4 of the upper surface of the upper case 2, extending from the other end 1b in the longitudinal direction of the device case 1 to the input display unit 4.
[0012] As shown in Figures 1 and 3, the input display unit 4 has a transparent touch panel 4b stacked on the upper surface of the display panel 4a. The display panel 4a is a planar display element such as a liquid crystal display element or an EL (electroluminescent) display element, and is configured to display information electro-optically. The transparent touch panel 4b is configured to allow information to be input by touching it while viewing the information displayed on the display panel 4a.
[0013] As shown in FIG. 1, the key input unit 5 includes a plurality of key buttons 5a arranged in a region on the upper surface of the upper case 2 on the other end 1b side of the device case 1, and a switch substrate (not shown) disposed inside the upper case 2. The plurality of key buttons 5a include a numeric keypad, function keys, etc., and also include an upper surface trigger key. The switch substrate is disposed corresponding to the plurality of key buttons 5a inside the upper case 2 below the plurality of key buttons 5a.
[0014] In this case, inside the upper case 2, as shown in FIG. 3, a circuit board 6 is disposed substantially corresponding to the input display unit 4. This circuit board 6 is for electrically controlling the entire portable terminal. That is, various electronic components 6a necessary for the portable terminal are mounted on this circuit board 6, and in addition, the input display unit 4, the key input unit 5, an optical reading unit (not shown) to be described later, the connection electrode unit 12, the power supply terminal unit 18, etc. are electrically connected.
[0015] On the other hand, on the back surface of the device case 1, that is, the lower surface of the lower case 3 (the upper surface in FIG. 2), as shown in FIG. 2, a storage convex portion 7 and a battery cover 8 are provided. The storage convex portion 7 is provided in a narrow region about 1 / 4 from one end 1a to the other end 1b side in the longitudinal direction of the device case 1. The battery cover 8 is provided in a region excluding the storage convex portion 7, that is, in a wide region about 3 / 4 extending from the other end 1b to the storage convex portion 7 in the longitudinal direction of the device case 1.
[0016] As shown in FIGS. 2 and 4, the storage convex portion 7 includes a first inclined surface 7a inclined toward one end 1a side of the device case 1 and a second inclined surface 7b inclined toward the other end 1b side of the device case 1, and has a triangular longitudinal cross-sectional shape and is formed in a substantially mountain shape as a whole. In this case, an optical window portion 7c is provided on the first inclined surface 7a. Also, an optical reading unit (not shown) is stored inside the storage convex portion 7.
[0017] The optical reading unit includes a scanner unit, which is an imaging means. The scanner unit comprises a laser reading unit and a camera unit, and is provided corresponding to the optical window unit 7c of the first inclined portion 7a of the storage protrusion 7. The laser reading unit reads the product code by irradiating a laser beam onto the product code, such as the barcode of a product, and receiving the reflected light. The camera unit photographs subjects such as products, items, and 2D codes.
[0018] Furthermore, as shown in Figures 2 and 4, a belt attachment cover 9 is attached to the second inclined surface 7b of the storage projection 7 at an angle approximately parallel to the second inclined surface 7b. This belt attachment cover 9 closes an expanded storage recess (not shown) provided on the second inclined surface 7b of the storage projection 7 of the equipment case 1, and is attached to the second inclined surface 7b of the storage projection 7 by a screw member 9a.
[0019] As shown in Figures 2 and 3, the battery cover 8 is designed to open and close the battery compartment 10 inside the lower case 3. The battery cover 8 is roughly rectangular in shape, and a grip portion 8a is provided from the other end 1b of the device case 1 to the middle of the battery cover 8. This grip portion 8a is formed in a curved shape that gently protrudes toward the back side (top side in Figure 2) of the lower case 3, and a raised portion 8b is provided in this curved portion to be positioned between the index and middle fingers of the hand.
[0020] Furthermore, as shown in Figures 2 and 3, when the battery cover 8 is placed in the lower case 3, closing the battery compartment 10 of the lower case 3, the other end 8d of the battery cover 8 on the other end 1b side of the device case 1 is locked to the edge of the battery compartment 10, and the one end 8c of the battery cover 8 on the storage projection 7 side of the lower case 3 is positioned to the edge of the battery compartment 10. In this case, when the battery cover 8 is placed in the lower case 3, closing the battery compartment 10, the one end 8c is locked by the lock lever 11.
[0021] In other words, as shown in Figures 2 and 4, the lock levers 11 are provided on the lower case 3 located near both sides of one end 8c of the battery cover 8, which is positioned at the base of the second inclined surface 7b side of the storage projection 7. Each of these lock levers 11 comprises a substantially circular locking portion 11a and a lever portion 11b.
[0022] The nearly circular locking portion 11a is rotatably mounted on the lower case 3, as shown in Figures 2 and 4, and is configured to lock one end 8c of the battery cover 8 on the storage projection 7 side in a retractable manner. The lever portion 11b extends from the locking portion 11a toward the storage projection 7 side and is configured to rotate the locking portion 11a.
[0023] In this case, as shown in Figures 2 and 4, the lock lever 11 is positioned in a substantially fan-shaped lever storage recess 3a provided in the lower case 3, extending from one end 8c of the battery cover 8 on the storage projection 7 side to the base of the second inclined surface 7b of the storage projection 7. That is, the lock lever 11 is configured such that the lock portion 11a is rotatably mounted at a key point in the fan-shaped lever storage recess 3a, and the lever portion 11b swings within the fan-shaped lever storage recess 3a.
[0024] As a result, as shown in Figures 2 and 4, when the battery cover 8 closes the battery compartment 10 of the lower case 3 and the lower case 3 is positioned in the lower case 3, the lock lever 11b is swung within the lever storage recess 3a to rotate the locking part 11a in one direction, causing the locking part 11a to press one end 8c of the battery cover 8 against the edge of the battery compartment 10 and lock it.
[0025] Furthermore, as shown in Figures 2 and 4, the lock lever 11 is configured such that when the locking portion 11a locks one end 8c of the battery cover 8, the locking portion 11a is released when the lever portion 11b is swung in the opposite direction to rotate the locking portion 11a in the opposite direction.
[0026] On the other hand, as shown in Figures 1 and 2, a connection electrode section 12 is provided on the end face of the lower case 3 located on the other end 1b side of the device case 1. This connection electrode section 12 is electrically connected to an external device (not shown) to exchange information and charge the battery pack 13 in the battery storage section 10, and consists of multiple electrodes 12a arranged therein.
[0027] Furthermore, as shown in Figure 3, the upper case 2 of the equipment case 1 comprises a case body portion 14 made of a highly rigid material, and an outer peripheral cover portion 15 made of synthetic resin that covers the outer peripheral edge and bottom surface of the case body portion 14. The case body portion 14 is formed in a substantially flat shape from a highly rigid material such as a metal such as magnesium alloy, stainless steel, or aluminum alloy, or reinforced plastic, or a material made by weaving and hardening carbon fiber or glass fiber.
[0028] As shown in Figure 3, the case body portion 14 includes a first reinforcing portion 14a that extends from its outer peripheral edge and is thicker than the case body portion 14, and a second reinforcing portion 14b that protrudes in a frame shape from the lower surface of the first reinforcing portion 14a along the outer circumference of the case body portion 14. The outer peripheral cover portion 15 is provided to cover the outer circumference and lower surface of the case body portion 14, that is, the first reinforcing portion 14a, the second reinforcing portion 14b, and the lower surface of the case body portion 14.
[0029] Furthermore, as shown in Figure 3, the outer peripheral cover portion 15 is configured such that when the upper case 2 is mounted on top of the lower case 3, the outer peripheral surface of the outer peripheral cover portion 15 is in close contact with the upper and inner peripheral surfaces of the outer peripheral edge of the lower case 3. The outer peripheral cover portion 15 is provided with a packing retaining rib 15a, which corresponds to the second reinforcing portion 14b, projecting toward the lower case 3 in a frame shape.
[0030] In this case, as shown in Figure 3, a case packing groove 16 is provided inside the lower case 3 along its inner circumferential surface. A waterproof packing 17 is placed inside this case packing groove 16. As a result, when the equipment case 1 is mounted by stacking the upper case 2 on top of the lower case 3, the packing retaining rib 15a of the outer peripheral cover portion 15 is pushed into the case packing groove 16 of the lower case 3 by the second reinforcing portion 14b, thereby pressing down on the waterproof packing 17.
[0031] In other words, as shown in Figure 3, when the upper case 2 is pressed against the lower case 3, the second reinforcing portion 14b provided on the case body portion 14 of the upper case 2 pushes down the packing retaining rib 15a of the outer peripheral cover portion 15 and pushes it into the case packing groove 16 of the lower case 3, and this pushed-down packing retaining rib 15a presses down the waterproof packing 17 inside the case packing groove 16 of the lower case 3.
[0032] Furthermore, as shown in Figure 3, the equipment case 1 is configured such that when the waterproof packing 17 in the case packing groove 16 is pressed down by the packing retaining rib 15a, the outer surface of the outer peripheral cover portion 15 is positioned in close contact with the upper and inner surfaces of the outer peripheral edge of the lower case 3.
[0033] Incidentally, as shown in Figures 4 to 7, the battery storage section 10 inside the device case 1 houses the battery pack 13, which is a battery module, and is formed to be approximately the same size as the battery pack 13. On one side of this battery storage section 10, that is, on the lower side of the second inclined surface 7b of the storage protrusion 7, a power terminal section 18, which is a first terminal section and also a battery connection section, is provided.
[0034] As shown in Figures 6, 7, and 11, the power terminal section 18 is electrically connected to the battery pack 13 when the battery pack 13 is housed in the battery compartment 10, and is equipped with a plurality of upright terminals 18a. These plurality of upright terminals 18a are arranged along the short side of the device case 1 in an upright position on a second base portion, which is a base portion 20, provided at the bottom of the battery compartment 10. That is, the plurality of upright terminals 18a are supported by a guide support portion 20a, which is a second base portion provided on the base portion 20.
[0035] As shown in Figures 3, 4, and 8, the battery pack 13 comprises a battery body 21 and a battery terminal portion 22, which is a second terminal portion and also a connection terminal. The battery body 21 comprises a rechargeable battery portion 21a and a cover case 21b that covers and protects the rechargeable battery portion 21a, and these are formed in a substantially rectangular plate shape. The battery terminal portion 22 is provided protruding from one end 13a of the battery pack 13.
[0036] As shown in Figures 4 to 8, the battery terminal section 22 is equipped with multiple clamping terminals 22a that individually clamp and electrically connect to multiple upright terminals 18a in the power terminal section 18 within the battery storage section 10. Each of these clamping terminals 22a is made by bending a conductive plate such as metal into a U-shape, and is arranged in the short direction perpendicular to the longitudinal direction of the battery pack 13 via an insulating portion 22b.
[0037] As shown in Figures 7 and 8, a first protective guide portion 23 is provided on the outer circumference of the battery terminal portion 22 to protect the battery terminal portion 22. This first protective guide portion 23 comprises a first side wall portion 23a and a first roof portion 23b. The first side wall portion 23a is configured to protect both sides of the battery terminal portion 22 in the direction of arrangement of the plurality of clamping terminals 22a and to be guided by the guide support portion 20a of the base portion 20.
[0038] In other words, as shown in Figures 7 and 8, the first side wall portion 23a also serves as a guide portion, with its opposing surface guiding both sides of the guide support portion 20a of the base portion 20 when the battery terminal portion 22 of the battery pack 13 is connected to the power terminal portion 18 in the battery storage portion 10. The first roof portion 23b is configured to protect one side of the battery pack 13 in the direction perpendicular to the arrangement direction of the multiple clamping terminals 22a of the battery terminal portion 22, that is, in the front and back direction.
[0039] On the other hand, one side of the battery storage section 10, that is, the side of the storage protrusion 7, is provided with a second protective guide section 24, as shown in Figures 4 to 6, which guides the first protective guide section 23 and connects the battery terminal section 22 to the power terminal section 18. This second protective guide section 24 comprises a second side wall section 24a, a second roof section 24b, and a second rear section 24c.
[0040] As shown in Figures 4 to 6, the second side wall portion 24a is provided on both sides in the arrangement direction of the multiple upright terminals 18a of the power terminal portion 18, and is configured to slidely guide and cover the first side wall portion 23a of the first protective guide portion 23. This second side wall portion 24a is provided at an angle from the tip of the second roof portion 24b toward the lower part of the second rear portion 24c.
[0041] As shown in Figures 4 to 6, the second roof portion 24b is provided on the power terminal portion 18 side opposite the bottom of the battery storage portion 10 and is configured to slidely guide and cover the first roof portion 23b of the first protective guide portion 23. The second rear portion 24c is provided at the inner end between the second side wall portion 24a and the second roof portion 24b and is configured to protect the tip of the first protective guide portion 23.
[0042] Furthermore, as shown in Figures 5, 6, and 11, a guide inclined portion 25, which is a third guide portion, is provided at the tip of the base portion 20 located on one side within the battery storage portion 10, that is, at the end on the inner side of the battery storage portion 10. In addition, as shown in Figure 8, an arc-shaped chamfered portion 23c is provided at the protruding tip of the first side wall portion 23a of the first protective guide portion 23, which slides along the guide inclined portion 25 of the base portion 20.
[0043] As a result, the guide inclined portion 25 of the base portion 20 is configured to rotate the battery pack 13 while gradually pushing up the chamfered portion 23c of the protruding tip of the first side wall portion 23a of the first protective guide portion 23, as shown in Figures 6, 8, and 11, thereby guiding and connecting the battery terminal portion 22 to the power terminal portion 18.
[0044] In other words, as shown in Figures 11(a) to 11(c), when the battery pack 13 is tilted relative to the bottom of the battery storage compartment 10, the chamfered portion 23c at the tip of the first side wall portion 23a of the first protective guide portion 23 is brought into contact with the bottom of the battery storage compartment 10, and the battery terminal portion 22 is slid toward the power terminal portion 18, the chamfered portion 23c of the first side wall portion 23a is gradually pushed upward as it slides.
[0045] Furthermore, as shown in Figures 11(a) to 11(c), the guide inclined portion 25 is configured such that, as the chamfered portion 23c of the first side wall portion 23a is gradually pushed up and slides, the arc-shaped chamfered portion 23c of the first side wall portion 23a rotates the battery pack 13 so as to gradually reduce its inclination, bringing the battery terminal portion 22 closer to the power terminal portion 18 so as to intersect with it, and connecting the battery terminal portion 22 to the power terminal portion 18 in a state where it is almost perpendicular to the power terminal portion 18.
[0046] In this case, as shown in Figures 8 and 11, the lower surface of the first side wall portion 23a of the battery pack 13, opposite to the first roof portion 23b, is provided with a set recess 23d where the base portion 20 is placed when the battery terminal portion 22 is connected to the power terminal portion 18 almost perpendicularly. The depth of this set recess 23d is approximately the same as the vertical thickness of the base portion 20, and when the base portion 20 is placed, the lower surface (upper surface in Figure 8), which is one surface of the battery pack 13, is in close contact with the bottom of the battery storage portion 10.
[0047] Furthermore, as shown in Figures 5 to 7, a first card mounting section 26 and a second card mounting section 27 are provided on both sides of the power terminal section 18 within the battery storage section 10, corresponding to both sides of one end of the battery pack 13 housed in the battery storage section 10, that is, the end on the battery terminal section 22 side. These first card mounting section 26 and second card mounting section 27 are designed to allow the insertion and removal of cards 29, such as SIM cards (communication cards) and memory cards.
[0048] In other words, as shown in Figures 5 to 7, the first card mounting section 26 and the second card mounting section 27 are arranged side by side along the shorter direction of the device case 1 on both sides of the power terminal section 18 inside the device case 1, corresponding to the base of the second inclined surface 7b of the storage protrusion 7 of the device case 1. As a result, the first card mounting section 26 and the second card mounting section 27 are configured so that a card 29 can be inserted and removed from the inside of the battery storage section 10.
[0049] Incidentally, as shown in Figures 3, 5, 9, and 10, the battery storage section 10 of the device case 1 is provided with an inner wall surface 30 along the inner circumference of the opening 10a. Multiple locking pieces 31 are provided on this inner wall surface 30, extending toward the opening 10a side of the battery storage section 10, and extending from the inner wall surface 30 toward the interior of the battery storage section 10, with a predetermined gap S between them and the inner wall surface 30.
[0050] As shown in Figures 3 and 5, these multiple locking pieces 31 are designed to flex and deform in the direction of moving toward and away from the inner wall surface 30 of the battery storage section 10, and each is provided with a locking hole 31a. Multiple sets of these multiple locking pieces 31 are provided on opposing inner wall surfaces 30 within the battery storage section 10, arranged along the longitudinal direction of the device case 1 in a manner that faces each other.
[0051] On the other hand, as shown in Figures 3, 9, and 10, the battery cover 8 includes a cover body 32 that closes the opening 10a of the battery storage section 10 of the device case 1. On the inner surface of this cover body 32, a support frame 33 is continuously provided in a frame shape along the inner circumference of the opening 10a of the battery storage section 10. This support frame 33 is inserted into the gap S between the multiple locking pieces 31 in the battery storage section 10 and the inner wall surface 30, and is detachably locked to the locking pieces 31.
[0052] As shown in Figures 3, 9, and 10, the inner surface of the support frame 33 is provided with a plurality of engaging protrusions 33a. These multiple engaging protrusions 33a are configured to be inserted into and locked into each of the locking holes 31a of the multiple locking pieces 31 when the support frame 33 is pushed into the gap S between the multiple locking pieces 31 and the inner wall surface 30. In addition, a waterproof packing 34 is provided on the outer circumferential surface of the support frame 33, which is inserted together with the support frame 33 into the gap S between the multiple locking pieces 31 and the inner wall surface.
[0053] As shown in Figures 3, 9, and 10, the waterproof packing 34 is made of an elastic material such as rubber or elastomer and is attached to the outer circumferential surface of the support frame 33, except for the areas corresponding to the multiple engaging protrusions 33a. The outer circumferential surface of the waterproof packing 34 is provided with elastic protrusions 34a that are pressed against the inner wall surface 30 of the battery storage section 10 and undergo elastic deformation.
[0054] As shown in Figures 3, 9, and 10, when the support frame 33 is inserted into the gap S between the multiple locking pieces 31 and the inner wall surface 30, and the engaging projection 33a of the support frame 33 is inserted into each locking hole 31a of the multiple locking pieces 31 and locked, the elastic projection 34a is pressed against the inner wall surface 30 of the battery storage section 10, and is configured to slightly elastically return to a stable shape.
[0055] Furthermore, as shown in Figures 3, 9, and 10, the battery compartment 10 and the battery cover 8 are equipped with a guide lock section 35 that guides the support frame 33 of the battery cover 8 between the multiple locking pieces 31 inside the battery compartment 10 and the inner wall surface 30, thereby locking the support frame 33 to the multiple locking pieces 31. This guide lock section 35 includes a first guide section 36 that guides the support frame 33 of the battery cover 8 between the multiple locking pieces 31 inside the battery compartment 10 and the inner wall surface 30, and a second guide section 37 that pushes the support frame 33 into the gap S between the multiple locking pieces 31 and the inner wall surface 30, thereby locking it to the multiple locking pieces 31.
[0056] As shown in Figures 9 and 10, the first guide portion 36 comprises a first guide inclined surface 36a and a second guide inclined surface 36b. The first guide inclined surface 36a is provided at the end of the locking piece 31 on the open side of the opening 10a of the battery storage portion 10, inclined from its end face toward the inner wall surface 30 of the battery storage portion 10. The second guide inclined surface 36b is provided substantially parallel to the first guide inclined surface 36a on the insertion side (lower side in Figure 8) of the engaging projection 33a of the support frame 33 of the battery cover 8, which is pushed into the gap S between the locking piece 31 and the inner wall surface 30 inside the battery storage portion 10.
[0057] As a result, as shown in Figures 9 and 10, when closing the opening 10a of the battery storage section 10 with the battery cover 8, the first guide section 36 is configured to slide along the first guide inclined surface 36a while the second guide inclined surface 36b of the support frame 33 is in contact with the first guide inclined surface 36a of the locking piece 31, thereby guiding the engaging projection 33a of the support frame 33 and the waterproof packing 34 into the gap S between the inner wall surface 30 of the battery storage section 10 and the plurality of locking pieces 31, while allowing each locking piece 31 to bend.
[0058] As shown in Figures 9 and 10, the second guide section 37 includes a first guide insertion surface 37a and a second guide insertion surface 37b. The first guide insertion surface 37a is provided extending from the lower end of the first guide inclined surface 36a of the plurality of locking pieces 31 on the inner wall surface 30 side of the battery storage section 10 to the locking hole 31a of the locking piece 31.
[0059] In other words, as shown in Figures 9 and 10, the first guide insertion surface 37a is provided substantially perpendicular to the insertion direction in which the support frame 33 is inserted into the gap S between the inner wall surface 30 and the plurality of locking pieces 31 inside the battery storage section 10. The second guide insertion surface 37b is provided substantially parallel to the first guide insertion surface 37a toward the tip of the engaging projection 33a of the support frame 33 on the locking hole 31a side.
[0060] As a result, as shown in Figures 9 and 10, the second guide portion 37 is configured to push the support frame 33 and waterproof packing 34, which are guided into the gap S between the locking piece 31 in the battery storage portion 10 and the inner wall surface 30, into the gap S between the inner wall surface 30 in the battery storage portion 10 and the multiple locking pieces, causing the elastic projection 34a of the waterproof packing 34 to press against the inner wall surface 30 of the battery storage portion 10 and elastically deform, and to maintain this state so that the engaging projection 33a engages with the locking hole 31a.
[0061] In this case, as shown in Figures 9 and 10, the multiple locking pieces 31 and elastic projections 34a are configured such that when the multiple engaging projections 33a engage with each locking hole 31a of the multiple locking pieces 31, the multiple locking pieces 31 elastically return to their original shape, and the elastic projections 34a also elastically return slightly to a stable shape.
[0062] Furthermore, as shown in Figures 9 and 10, the engaging projection 33a of the support frame 33 is provided with a draft inclined surface 33b that bites into the locking hole 31a of the locking piece 31 and presses against the inner surface of the locking hole 31a at an inclination. This draft inclined surface 33b is inclined with a draft angle θ from the end of the engaging projection 33a that bites into the opening 10a of the battery storage section 10 toward the opening 10a. In other words, the draft angle θ of this draft inclined surface 33b is set according to the deflection deformation force of the locking piece 31 in the direction of contact with and separation from the inner wall surface 30 of the battery storage section 10.
[0063] As a result, as shown in Figures 9 and 10, when the battery cover 8 is removed from between the inner wall surface 30 of the battery storage section 10 and the multiple locking pieces 31 while the opening 10a of the battery storage section 10 is closed, the inner surface of the locking hole 31a of the locking piece 31 slides relative to the inclined surface 33b of the engaging projection 33a, allowing the engaging projection 33a to easily disengage from the locking hole 31a of the locking piece 31.
[0064] In this case, the edge of the locking hole 31a of the locking piece 31, that is, the edge on the inner surface of the locking hole 31a where the inclined surface 33b of the engaging projection 33a is locked, is provided with an arc-shaped chamfered portion 31b that slides relative to the inclined surface 33b, as shown in Figures 9 and 10. This arc-shaped chamfered portion 31b is configured to facilitate the relative sliding of the engaging projection 33a along the inclined surface 33b when removing the battery cover 8 from the battery storage compartment 10.
[0065] Furthermore, the multiple sets of locking pieces 31, that is, the multiple sets of locking pieces 31 arranged along the longitudinal direction of the device case 1 and facing each other, are set such that, as shown in Figures 3 to 5, the distance between opposing pairs of locking pieces 31 gradually narrows from one end 8c to the other end 8d of the battery cover 32 when the battery cover 8 rotates the cover body 32 with the other end 8d of the cover body 32 as a pivot point to close the opening 10a of the battery storage section 10.
[0066] In other words, the amount of engagement of each of the multiple engaging projections 33a with respect to each of the locking holes 31a of the multiple locking pieces 31 is set to gradually increase from one end 8c to the other end 8d of the battery cover 8, as shown in Figures 4, 5, and 9. As a result, when the battery cover 8 is rotated with the other end 8d as a pivot point to be removed from the battery storage section 10, the engagement force of the engaging projections 33a with respect to the locking holes 31a is weak at the one end 8c of the battery cover 8, and gradually increases as you move from the one end 8c to the other end 8d of the battery cover 8.
[0067] Therefore, as shown in Figures 4, 5, and 9, when the battery cover 8 is removed from the battery storage section 10 by rotating it with the other end 8d as a pivot point, the engagement force of the engaging projection 33a with the locking hole 31a on the one end 8c side of the battery cover 8 is weak, making it easier to release the engagement of the engaging projection 33a with the locking hole 31a on the one end 8c side of the battery cover 8.
[0068] Furthermore, as shown in Figures 4, 5, and 9, when removing the battery cover 8 from the battery storage compartment 10 by rotating it with the other end 8d as a pivot point, even if the engagement force of the engaging projection 33a with the locking hole 31a is strong and difficult to remove as you move from the one end 8c side to the other end 8d side of the battery cover 8, the battery cover 8 rotates with the other end 8d as a pivot point and stands upright, making it easier to release the engagement of the engaging projection 33a with the locking hole 31a as you move from the one end 8c side to the other end 8d side of the battery cover 8.
[0069] In this case, as shown in Figures 2, 4 to 6, both sides of the short-side of the device case 1 located on one end 8c of the battery cover 8 are provided with finger notches 38 on both sides of the short-side of the one end 8c of the battery cover 8 to make it easier to grip with fingers. This configuration makes it easier to remove the battery cover 8 from the battery storage compartment 10 by gripping the finger notches 38 with fingers and rotating the battery cover 8 using the other end 8d as a pivot point.
[0070] Next, I will explain how this mobile device works. First, remove the battery cover 8 from the device case 1 and place the battery pack 13 inside the battery compartment 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 releasing the lock on one end 8c of the battery cover 8 by the lock portion 11a.
[0071] In this state, place your fingers on the finger-shaped notches 38 provided on both sides of the device case 1 corresponding to one end 8c of the battery cover 8, and pull up the end 8c of the battery cover 8 from the battery compartment 10. Then, with the other end 8d as a pivot point, the end 8c of the battery cover 8 rotates upward and is removed from the battery compartment 10, opening the battery compartment 10.
[0072] In this state, the battery pack 13 is placed inside the battery compartment 10. At this time, the battery pack 13 is tilted and inserted into the battery compartment 10, as shown in Figure 11(a), with the battery terminal portion 22 protruding from one end 13a of the battery pack 13 facing the power terminal portion 18 located on one side of the battery compartment 10 at one end 1a of the device case 1.
[0073] Then, the arc-shaped chamfered portion 23c of the first side wall portion 23a of the first protective guide portion 23 of the battery pack 13 comes into contact with the bottom of the battery storage portion 10, and in this state, the battery pack 13 is slid toward the power terminal portion 18. Then, the chamfered portion 23c of the first protective guide portion 23 slides while being gradually raised by the guide inclined portion 25 of the base portion 20 of the power terminal portion 18.
[0074] At this time, the curved chamfered portion 23c of the first side wall portion 23a rotates the battery pack 13 so that its tilt gradually decreases, and the battery terminal portion 22 approaches the power terminal portion 18 so as to intersect with it. Then, when the curved chamfered portion 23c of the first side wall portion 23a rides over the guide inclined portion 25, the first protective guide portion 23 of the battery pack 13 is guided by the second protective guide portion 24 inside the battery storage portion 10, and the battery terminal portion 22 is connected to the power terminal portion 18 in a state that is almost perpendicular to it.
[0075] In other words, when 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 first side wall portion 23a of the first protective guide portion 23 is guided by the second side wall portion 24a of the second protective guide portion 24, and the opposing surface of the first side wall portion 23a is guided by both sides of the guide support portion 20a of the base portion 20. As a result, the first protective guide portion 23 is protected by the first side wall portion 23a being covered by the second side wall portion 24a of the second protective guide portion 24, and the first roof portion 23b is protected by the second roof portion 24b of the second protective guide portion 24.
[0076] When 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, each clamping terminal 22a of the battery terminal portion 22 of the battery pack 13 clamps and contacts each upright terminal 18a of the power terminal portion 18, connecting to each upright terminal 18a. As a result, the battery pack 13 is stored in the battery storage portion 10.
[0077] In other words, when the battery terminal portion 22 is connected to the power terminal portion 18 almost perpendicularly, the base portion 20 is positioned in the set recess 23d provided on the side of the battery pack 13 opposite to the first roof portion 23b. As a result, the battery pack 13 is stored in the battery storage portion 10 with one side of the battery pack 13, the bottom surface, in close contact with the bottom of the battery storage portion 10.
[0078] Then, the battery compartment 10 is closed with the battery cover 8. At this time, the other end 8d of the battery cover 8 is locked to the end of the opening 10a of the battery compartment 10 located on the other end 1b side of the device case 1, and the battery cover 8 is rotated using the locked other end 8d of the battery cover 8 as a pivot point, bringing one end 8c of the battery cover 8 closer to the end of the opening 10a of the battery compartment 10 located on the one end 1a side of the device case 1.
[0079] Then, the support frame 33 of the battery cover 8 is sequentially pushed between the multiple sets of locking pieces 31 provided on the inner wall surface 30 of the battery storage section 10 and the inner wall surface 30. That is, the multiple sets of locking pieces 31 are provided in multiple sets, arranged along the longitudinal direction of the device case 1, facing each other on the opposing inner wall surfaces 30 of the battery storage section 10. In this case, the multiple sets of locking pieces 31 are set so that the distance between opposing pairs of locking pieces 31 gradually narrows from one end 8c of the cover body 32 to the other end 8d.
[0080] Furthermore, in these multiple sets of locking pieces 31, the amount of engagement of each of the multiple engaging projections 33a with respect to each of the locking holes 31a of the multiple locking pieces 31 gradually increases from one end 8c of the battery cover 8 towards the other end 8d. As a result, when the battery cover 8 rotates with the other end 8d as a pivot point to attach the battery storage section 10, the engagement force of the engaging projections 33a with respect to the locking holes 31a is strong at the other end 8d of the battery cover 8, and gradually weakens as you move from the other end 8d towards the one end 8c of the battery cover 8.
[0081] Therefore, when the battery cover 8 rotates with its other end 8d as a pivot point and is attached to the battery compartment 10, the force required to push the battery cover 8 in gradually increases from one end 8c towards the other end 8d. As a result, the support frame 33 of the battery cover 8 is sequentially pushed between the inner wall surface 30 of the battery compartment 10 and the multiple locking pieces 31, ensuring secure attachment. At this time, the guide lock portion 35 ensures that the support frame 33 of the battery cover 8, together with the waterproof packing 34, is properly pushed between the inner wall surface 30 of the battery compartment 10 and the multiple locking pieces 31.
[0082] In other words, when closing the opening 10a of the battery storage section 10 with the battery cover 8, the first guide portion 36 of the guide lock portion 35 slides along the first guide inclined surface 36a with the second guide inclined surface 36b of the support frame 33 in contact with the first guide inclined surface 36a of the locking piece 31, smoothly and effectively guiding the engaging projection 33a of the support frame 33 and the waterproof packing 34 into the gap S between the inner wall surface 30 of the battery storage section 10 and the locking piece 31 while allowing the locking piece 31 to flex.
[0083] 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 engaging projection 33a of the support frame 33 is guided along the first guide insertion surface 37a of the second guide portion 37 provided on the locking piece 31. As a result, the elastic projection 34a of the waterproof packing 34 is pressed against the inner wall surface 30 of the battery storage section 10 and elastically deforms. 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 projection 33a reliably and effectively engages with the locking hole 31a.
[0084] In this way, when the engaging projection 33a engages with the locking hole 31a, the multiple locking pieces 31 return to their original state, and the elastic projection 34a slightly elastically returns to a stable shape. As a result, the elastic projection 34a is pressed firmly and securely against the inner wall surface 30 of the battery compartment 10 in a stable shape. This ensures that the battery compartment 10 is waterproofed reliably and effectively.
[0085] In this state, one end 8c of the battery cover 8 is locked by the lock lever 11. That is, the lever portion 11b of the lock lever 11 is swung within the lever housing recess 3a to rotate the lock portion 11a, and this rotated lock portion 11a locks one end 8c of the battery cover 8. This ensures that the battery cover 8 is securely and properly attached to the battery housing 10.
[0086] Next, we will explain the case where a user holds and uses such a mobile device in their hand. In this case, place the fingers other than the thumb on the back of the device case 1, and place the thumb on the input display section 4 or the key input section 5 of the device case 1, and grasp the device case 1 so as to wrap around the battery cover 8.
[0087] In this state, the user uses their thumb to input information on the input display unit 4 or the key input unit 5. At this time, the information displayed on the display panel 4a of the input display unit 4 is visible through the transparent touch panel 4b, allowing the user to touch the transparent touch panel 4b while viewing the information displayed on the display panel 4a.
[0088] Furthermore, in this state, if either the upper trigger key 5a of the key input unit 5 or the side trigger key 1c provided on the side of the device case 1 is operated, the scanner unit 9b of the optical reading unit 9 is driven. Then, the laser reading unit of the scanner unit 9b irradiates the product code of the product through the optical window unit 7c of the retractable protrusion unit 7 with a laser beam, receives the reflected light and reads the product code.
[0089] At this time, the camera unit of the scanner unit 9b photographs the subject, such as a product, item, or 2D code. As a result, the product code read by the laser reader is displayed on the input display unit 4 and registered in the memory unit of the circuit board 6. Similarly, the subject, such as a product, item, or 2D code, photographed by the camera unit is displayed on the input display unit 4 and registered in the memory unit of the circuit board 6.
[0090] If such a portable device is dropped from a table or from the hand, the device case 1 will be subjected to the impact of the fall. At this time, multiple sets of engaging protrusions 33a provided on the support frame 33 of the battery cover 8 are engaged with the locking holes 31a of multiple sets of locking pieces 31 provided on the inner wall surface 30 of the battery storage section 10, so deformation of the battery cover 8 due to the impact of the fall is suppressed. As a result, the battery cover 8 will not come off the battery storage section 10 due to the impact, and the battery pack 13 stored inside the battery storage section 10 will not fall out.
[0091] Next, we will explain how to replace the battery pack 13 by removing the battery cover 8 from the battery compartment 10. In this case, as described above, the lock lever 11 is operated to release the lock on one end 8c of the battery cover 8 by the locking part 11a, and in this state, the fingers are placed on the finger-holding notches 38 provided on both sides of the device case 1 corresponding to one end 8c of the battery cover 8, and the end 8c side of the battery cover 8 is pulled up from the battery storage part 10.
[0092] Then, the battery cover 8 rotates with the other end 8d as a pivot point, with the one end 8c facing upward. At this time, the distance between opposing pairs of locking pieces 31 in the multiple sets of locking pieces 31 is set to gradually narrow from the one end 8c side to the other end 8d side of the cover body 32, and the amount of engagement of each of the multiple engaging projections 33a with respect to each locking hole 31a of the multiple locking pieces 31 gradually increases from the one end 8c side to the other end 8d side of the battery cover 8.
[0093] Therefore, when the battery cover 8 is removed from the battery compartment 10 by rotating with the other end 8d as a pivot point, the engagement force of the engaging projection 33a with the locking hole 31a at one end 8c of the battery cover 8 is weak, and the engagement force of the engaging projection 33a with the locking hole 31a gradually increases as you move from the one end 8c to the other end 8d of the battery cover 8. Therefore, when the battery cover 8 is gradually tilted in the direction of standing upright relative to the battery compartment 10, the initial pulling force is light, so the battery cover 8 can be easily rotated, and the engagement of the multiple engaging projections 33a with each locking hole 31a of the multiple locking pieces 31 is sequentially released.
[0094] In this manner, when the battery cover 8 rotates with its other end 8d as a pivot point to remove the battery compartment 10, the support frame 33 of the battery cover 8 sequentially disengages from between the inner wall surface 30 of the battery compartment 10 and the multiple locking pieces 31, starting from the one end 8c side of the battery cover 8 towards the other end 8d side. At this time, the engaging projection 33a of the support frame 33 easily disengages from the locking hole 31a of the locking piece 31 due to the inclined disengagement surface 33b.
[0095] In other words, the draft angle θ of the inclined surface 33b is set according to the bending deformation force of the locking piece 31 in the direction of contact with and separation from the inner wall surface 30 of the battery storage section 10. Therefore, when the support frame 33 of the lid body 32 is removed from between the inner wall surface 30 of the battery storage section 10 and the multiple locking pieces 31 while the battery lid 8 is blocking the opening 10a of the battery storage section 10, the inner surface of the locking hole 31a of the locking piece 31 slides relative to the inclined surface 33b of the engaging projection 33a. As a result, the engaging projection 33a can easily be removed from the locking hole 31a of the locking piece 31.
[0096] At this time, the arc-shaped chamfered portion 31b provided on the edge of the locking hole 31a of the locking piece 31, that is, the edge on the inner surface of the locking hole 31a where the inclined surface 33b of the engaging projection 33a is locked, slides relative to the inclined surface 33b. In this case, the locking piece 31 deforms by bending away from the inner wall surface 30, and the elastic projection 34a of the waterproof packing 34 is pressed against the inner wall surface 30 and undergoes elastic deformation.
[0097] Therefore, when removing the battery cover 8 from the battery compartment 10, the arc-shaped chamfered portion 31b slides relatively down along the inclined surface 33b of the engaging projection 33a, allowing the engaging projection 33a to smoothly disengage from the locking hole 31a of the locking piece 31. As a result, the engaging projection 33a can be easily and efficiently removed from the locking hole 31a of the locking piece 31.
[0098] In this way, when the battery cover 8 is removed from the battery compartment 10, the battery pack 13 inside the battery compartment 10 is exposed. To remove the battery pack 13 from inside the battery compartment 10, the other end 13b of the battery pack 13, which is located on the other end 1b side of the device case 1, is pulled up from inside the battery compartment 10.
[0099] Then, the battery pack 13 gradually tilts and rotates diagonally upward around the arc-shaped chamfered portion 23c of the first protective guide 23 provided at one end 13a of the battery pack 13, and slides toward the other end 1b of the device case 1. This allows the battery pack 13 to be removed from inside the battery storage compartment 10. In this state, the battery pack 13 can be replaced.
[0100] Furthermore, when the battery pack 13 is removed from the battery compartment 10, the SIM card (communication card) or memory card or other card 29 inserted in the first card slot 26 and the second card slot 27 can be replaced. That is, the card 29 inserted in the first card slot 26 and the second card slot 27 can be removed from the first card slot 26 and the second card slot 27 and placed into the battery compartment 10 by operating a release lever (not shown) or by pushing the card 29.
[0101] Then, the new card 29 is inserted into the first card slot 26 and the second card slot 27 from inside the battery compartment 10. When replacing the card 29 in this way, the inside of the battery compartment 10 is significantly wider than the card 29, making it easy to insert and remove the card 29 from the inside of the battery compartment 10 into the first card slot 26 and the second card slot 27, thus enabling smooth replacement of the card 29.
[0102] In this case, a 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 protruding from one end 13a of the battery pack 13. As a result, the first card mounting section 26 and the second card mounting section 27 do not get in the way, and the battery terminal section 22 of the battery pack 13 can be properly connected to the power terminal section 18 in the battery storage section 10.
[0103] Furthermore, the first card mounting section 26 and the second card mounting section 27 are arranged side by side along the shorter direction of the device case 1 on both sides of the power terminal section 18, within the device case 1, corresponding to the base of the second inclined surface 7b of the storage protrusion 7 of the device case 1. This allows the first card mounting section 26 and the second card mounting section 27 to be compactly installed within the device case 1. As a result, the mounting density within the device case 1 is increased, and the insertion and removal of the card 29 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.
[0104] Thus, this mobile terminal comprises a battery storage unit 10 with a first terminal portion, a power terminal portion 18, provided at one end, and a battery pack 13, which is a battery module, having a second terminal portion, a battery terminal portion 22, electrically connected to the power terminal portion 18, formed to protrude toward one end 13a. The power terminal portion 18 has an upright terminal 18a provided to stand up from the bottom surface of the battery storage unit 10, and a first base portion, a guide support portion 20a, that supports the upright terminal 18a. The battery terminal portion 22 has opposing surfaces of a pair of first side wall portions 23a, which are guide portions that can fit the guide support portion 20a between them when the battery pack 13 is stored in the battery storage unit 10, and a clamping terminal 22a that can clamp the upright terminal 18a. Thus, a simple structure allows for good connection between terminals without damaging them.
[0105] In other words, in this mobile terminal, the battery terminal portion 22 protruding from one end 13a of the battery pack 13 is protected by the first side wall portion 23a. When connecting the battery terminal portion 22 of the battery pack 13 to the power terminal portion 18 in the battery storage portion 10, the first side wall portion 23a is slid towards the power terminal portion 18 within the battery storage portion 10. As a result, the opposing surface of the first side wall portion 23a is guided by both sides of the guide support portion 20a, allowing the battery terminal portion 22 to be properly connected to the power terminal portion 18.
[0106] Therefore, this mobile terminal does not require a connecting member with special functions as described in prior art, and the structure is simple because the first side wall portion 23a protecting the battery terminal portion 22 is guided by the guide support portion 20a. Furthermore, because the first side wall portion 23a is guided by the guide support portion 20a while sliding towards the guide support portion 20a within the battery storage portion 10, the battery terminal portion 22 can be accurately connected to the power terminal portion 18, and the battery terminal portion 22 and the power terminal portion 18 can be connected well without damaging each other.
[0107] Furthermore, in this mobile terminal, the first terminal section, the power terminal section 18, is equipped with a base section 20, which is a second base section that supports the guide support section 20a. The base section 20 is provided with a guide inclination section 25 such that when the first side wall section 23a, which is a guide section, is slid toward the power terminal section 18 so as to press against the bottom surface of the battery storage section 10, the clamping terminal 22a of the battery terminal section 22 is guided toward the upright terminal 18a of the power terminal section 18. As a result, when the battery pack 13 is slid in an inclined position within the battery storage section 10 to connect the battery terminal section 22 to the power terminal section 18, the guide inclination section 25 can guide the first side wall section 23a, thereby regulating the height of the battery terminal section 22 relative to the power terminal section 18 and ensuring that it is always connected accurately and properly at a constant position.
[0108] In this case, the guide inclined portion 25 of this mobile terminal is provided to be inclined from one end 1a of the device case 1 toward the other end 1b. As a result, when the battery pack 13 is slid in an inclined position within the battery storage portion 10 to connect the battery terminal portion 22 to the power terminal portion 18, the guide inclined portion 25 can guide the first side wall portion 23a of the first protective guide portion 23 to gradually push up. This regulates the height of the battery terminal portion 22 relative to the power terminal portion 18, ensuring that it is always connected accurately and properly at a constant position.
[0109] Furthermore, in this mobile terminal, a base portion 20 is positioned on the surface of the first protective guide portion 23 opposite to the first roof portion 23b, that is, on the open side, and a set recess 23d is provided for bringing the battery body 32 into close contact with the bottom of the battery storage portion 10. As a result, when the first side wall portion 23a of the first protective guide portion 23 is gradually pushed up by the guide inclined portion 25 and positioned on the base portion 20, the base portion 20 can be positioned within the set recess 23d, thereby bringing the battery body 32 into close contact with the bottom of the battery storage portion 10, and thus the battery pack 13 can be properly positioned inside the battery storage portion 10.
[0110] In this case, the mobile terminal is provided with an arc-shaped chamfered portion 23c on the protruding tip of the first side wall portion 23a of the first protective guide portion 23, which slides along the guide inclined portion 25 of the base portion 20. As the chamfered portion 23c of the first protective guide portion 23 slides while gradually riding up on the guide inclined portion 25 of the base portion 20 of the power terminal portion 18, the arc-shaped surface of the chamfered portion 23c of the first side wall portion 23a can gradually reduce the tilt of the battery pack 13, allowing the battery pack 13 to move smoothly and efficiently towards the bottom of the battery storage portion 10.
[0111] Therefore, in this mobile terminal, when the chamfered portion 23c of the first side wall portion 23a rides over the guide inclined portion 25 and moves onto the base portion 20, the battery terminal portion 22 can be connected to the power terminal portion 18 in a state that is almost perpendicular to it, and the base portion 20 can be positioned in the set recess 23d, thereby allowing the battery body 32 to be in close contact with the bottom of the battery storage portion 10 and the battery pack 13 to be positioned well inside the battery storage portion 10.
[0112] In this case, the power terminal section 18, which is the first terminal section, has a second protective guide section 24, which is a protective section formed to cover the upright terminal 18a, the guide support section 20a, and the base section 20, with a predetermined opening provided therein. Furthermore, the guide inclination section 25 is inclined toward the opening direction of the opening, which is the opening between the second side wall section 24a and the second roof section 24b of the second protective guide section 24. As a result, when connecting the battery terminal section 22 to the power terminal section 18, the guide inclination section 25 can guide the first side wall section 23a of the first protective guide section 23 to gradually push up, thereby regulating the height of the battery terminal section 22 relative to the power terminal section 18 and ensuring that it is always connected accurately and properly at a constant position.
[0113] In the above-described embodiment, a battery cover 8 that closes the battery storage section 10 of the device case 1 was explained, but this invention is not limited to this and can be applied to various types of covers for closing openings provided in the device case.
[0114] Furthermore, in the embodiment described above, the battery terminal portion 22 of the battery pack 13 is provided with a plurality of clamping terminals 22a, and the power terminal portion 18 in the battery storage portion 10 is provided with a plurality of plate-shaped upright terminals 18a that are sandwiched between the clamping terminals 22a of the battery terminal portion 22. However, the present invention is not limited to this, and the battery terminal portion 22 may be formed with a plurality of plate-shaped terminals, and the power terminal portion 18 may be formed with a plurality of clamping terminals.
