[0012] Hereinafter, an embodiment of a mobile terminal to which the present invention is applied will be described with reference to FIGS. 1 to 3, this mobile terminal is an information terminal such as a handheld terminal for processing information, and includes a device case 1. This device case 1 is the terminal main body, and includes an upper case 2 on the front side and a lower case 3 on the back side, and is formed as a thin, generally rectangular box.
[0013] 1, an input display unit 4 and a key input unit 5 are provided in parallel on the surface of this device case 1, i.e., on the top surface of the upper case 2. The input display unit 4 is provided in a wide area of approximately 3 / 4 of the device case 1's length from one end 1a toward the other end 1b on the top surface of the upper case 2. The key input unit 5 is provided in the area excluding the input display unit 4, i.e., on the top surface of the upper case 2, in a narrow area of approximately 1 / 4 of the device case 1's length from the other end 1b to the input display unit 4.
[0014] As shown in Fig. 1, 3 or 4, the input display unit 4 is formed by laminating a transparent touch panel 4b on the upper surface of a display panel 4a. The display panel 4a is a flat display element such as a liquid crystal display element or an EL (electroluminescence) display element, and is configured to electro-optically display information. The transparent touch panel 4b is configured to input information by performing a touch operation while viewing the information displayed on the display panel 4a.
[0015] 1 or 3, the key input unit 5 includes a plurality of key buttons 5a arranged in an area on the other end 1b side of the device case 1 on the top surface of the top case 2, and a switch board 5b arranged inside the top case 2. The key buttons 5a include key buttons such as a numeric keypad and function keys, as well as an upper surface trigger key 5c. The switch board 5b is arranged in the top case 2 below the key buttons 5a (upper side in FIG. 3) in correspondence with the key buttons 5a.
[0016] In this case, as shown in Figures 3 and 4, a circuit board 6 is disposed inside the upper case 2 in correspondence with the input display unit 4. This circuit board 6 is for electrically controlling the entire mobile terminal. That is, this circuit board 6 is equipped with various electronic components 6a necessary for the mobile terminal, and is electrically connected to the input display unit 4, the switch board 5b of the key input unit 5, the optical reading unit 9 described below, the expansion connector 17, and the connection electrode unit 11.
[0017] On the other hand, a storage protrusion 7 and a battery lid 8 are provided on the back surface of the device case 1, i.e., the lower surface (upper surface in Fig. 2) of the lower case 3, as shown in Fig. 2. The storage protrusion 7 is provided in a narrow region of about 1 / 4 of the device case 1's length from one end 1a toward the other end 1b. The battery lid 8 is provided in the region excluding the storage protrusion 7, i.e., in a wide region of about 3 / 4 of the device case 1's length from the other end 1b to the storage protrusion 7.
[0018] 2 and 3, the storage protrusion 7 has a first inclined surface 7a inclined toward one end 1a of the device case 1 and a second inclined surface 7b inclined toward the other end 1b of the device case 1, and has a triangular cross section, so that the storage protrusion 7 is generally formed in a mountain shape. In this case, an optical window 7c is provided on the first inclined surface 7a. An optical reader 9 is stored inside the storage protrusion 7.
[0019] 3, the optical reading unit 9 includes a unit case 9a and a scanner unit 9b, which is an imaging means, attached to the unit case 9a. The unit case 9a is provided in the upper case 2 in correspondence with the storage protrusion 7 of the lower case 3, and is disposed so as to protrude into the storage protrusion 7 of the lower case 3.
[0020] As shown in Fig. 3, the scanner unit 9b includes a laser reading unit and a camera unit, and is attached to the unit case 9a in correspondence with the optical window 7c of the first inclined portion 7a of the storage protrusion 7. The laser reading unit irradiates a laser beam onto a product code such as a barcode on a product and receives the reflected light to read the product code. The camera unit photographs a subject such as a product, an article, or a two-dimensional code.
[0021] 2 and 3, the battery lid 8 opens and closes the battery storage section 3a in the lower case 3. The battery lid 8 is substantially rectangular, and has a grip 8a provided from the other end 1b of the device case 1 to the middle of the battery lid 8. The grip 8a is curved so as to gently protrude toward the back surface side of the lower case 3 (the upper surface side in FIG. 2), and the curved portion has a raised portion 8b that is to be placed between the index finger and middle finger of the hand.
[0022] 2 and 3, when the battery lid 8 is placed in the lower case 3 to cover the battery storage section 3a of the lower case 3, the other end 8d of the battery lid 8 on the other end 1b side of the device case 1 is engaged with the edge of the battery storage section 3a, and one end 8c of the battery lid 8 on the storage protrusion 7 side of the lower case 3 is placed on the edge of the battery storage section 3a. In this case, the battery lid 8 is configured such that one end 8c is locked by the lock lever 10 when the battery lid 8 is placed in the lower case 3 to cover the battery storage section 3a.
[0023] 2 and 5, the lock levers 10 are provided at locations on the lower case 3 located near both sides of one end 8c of the battery lid 8 located at the base of the second inclined surface 7b side of the storage protrusion 7. Each of these lock levers 10 includes a substantially circular lock portion 10a that is rotatably provided on the lower case 3 and that releasably locks one end 8c of the battery lid 8 on the storage protrusion 7 side, and a lever portion 10b that extends from this lock portion 10a toward the storage protrusion 7 side and rotates the lock portion 10a.
[0024] 2 and 5, these lock levers 10 are disposed in substantially sector-shaped lever storage recesses 3b provided in the lower case 3 from one end 8c of the battery lid 8 on the storage protrusion 7 side to the base of the second inclined surface 7b of the storage protrusion 7. That is, the lock lever 10 is configured so that the lock portion 10a is rotatably provided at a required position in the sector-shaped lever storage recess 3b, and the lever portion 10b swings within the sector-shaped lever storage recess 3b.
[0025] As a result, as shown in Figures 2 and 5, when the battery lid 8 is placed in the lower case 3 covering the battery storage section 3a of the lower case 3, and the lever portion 10b is swung within the lever storage recess 3b to rotate the lock portion 10a in one direction, the lock portion 10a presses one end 8c of the battery lid 8 against the edge of the battery storage section 3a to lock it.
[0026] In addition, as shown in Figures 2 and 5, when the lock portion 10a locks one end 8c of the battery lid 8, the lock portion 10a is released from the lock of one end 8c of the battery lid 8 by the lock portion 10a when the lever portion 10b is swung in the opposite direction to rotate the lock portion 10a in the opposite direction.
[0027] 1 to 3, a connection electrode section 11 is provided on an end surface of the lower case 3 located on the other end 1b side of the device case 1. This connection electrode section 11 is electrically connected to an external device (not shown) such as a cradle to transmit and receive information and charge the battery pack B in the battery storage section 3a, and has a plurality of electrodes 11a arranged thereon.
[0028] In this case, as shown in Figures 1 to 3, the connection electrode section 11 has a plurality of electrodes 11a covered and protected by an electrode cover 11b made of an elastic material such as rubber. The battery pack B includes a rechargeable battery B1 and a battery cover section B2. A side trigger key 1c is provided on the side of the device case 1.
[0029] 10, a hand belt 12 can be attached to the lower case 3 along the longitudinal direction of the device case 1. That is, one end 12a of the hand belt 12 is configured to be attached to a first belt mounting metal fitting 14 of the extension lid 13 attached to the second inclined surface 7b of the storage protrusion 7 of the lower case 3. The other end 12b of the hand belt 12 is configured to be attached to a first belt mounting hole 3c provided at the other end 1b of the device case 1 at the other end of the lower case 3.
[0030] As a result, the hand belt 12 is attached via the first belt mounting metal fitting 14 and the first belt mounting hole 3c, so that the hand belt 12 does not block the electrodes 11a from above. In other words, when connecting the connection electrode unit 11 to an external device such as a cradle, the connection can be made with the hand belt 12 still attached.
[0031] In this case, an extension connector section 50 is provided on the second inclined surface 7b of the storage protrusion 7 of the lower case 3. This extension connector section 50 includes an extension storage recess 15, an extension board 16, an extension connector 17, and an extension lid 13, as shown in Figs.
[0032] That is, as shown in Figs. 5 to 8, an expansion storage recess 15 is provided on the second inclined surface 7b of the storage protrusion 7, inclined approximately parallel to the second inclined surface 7b, and an expansion lid 13 is attached to this expansion storage recess 15. An extension board 16 is disposed in this expansion storage recess 15, inclined approximately parallel to the second inclined surface 7b. Furthermore, an expansion connector 17 is disposed at the bottom of this expansion storage recess 15, inclined approximately parallel to the second inclined surface 7b, and inclined with respect to the horizontal direction of the device case 1.
[0033] 3 and 6 to 8, the expansion connector 17 is electrically connected by inserting the board connector 16a of the expansion board 16, and is provided in a unit case 9a provided in the upper case 2, and is electrically connected to the circuit board 6 in the upper case 2 by a connection wire 17a. The expansion connector 17 is exposed inside the expansion storage recess 15 from an opening 15a at the bottom of the expansion storage recess 15, and is provided long along a short side direction perpendicular to the longitudinal direction of the device case 1, that is, along a direction perpendicular to the inclination direction of the bottom of the expansion storage recess 15.
[0034] 3 and 6 to 8, the extension board 16 is a card reading board (for example, a non-contact IC (Integrated Circuit) reader / writer board, an RFID (Radio Frequency Identifier) reader / writer board) for contactlessly reading information on a card such as a credit card. The extension board 16 includes a board connector 16a connected to an extension connector 17, and the extension connector 17 to which the board connector 16a is connected is electrically connected to the circuit board 6 in the upper case 2 by a connection wire 17a.
[0035] In this case, as shown in Figures 3, 6 to 8, a magnetic electrode 16b (see Figure 3) that captures card information by a magnetic field (induced electromotive force) is provided on the inner surface of the storage protrusion 7 of the lower case 3. This magnetic electrode 16b is electrically connected to the circuit board 6 in the upper case 2, and is electrically connected to the extension board 16 via this circuit board 6.
[0036] As a result, as shown in Figures 3 and 6 to 8, when a card such as a credit card is brought close to the outer surface of the storage protrusion 7 of the lower case 3, the magnetic electrode 16b magnetically captures the information signal of the card, and this captured magnetic information signal is read by the extension board 16 as card information.
[0037] 3 and 6 to 8, the extension board 16 is disposed in the extension storage recess 15 provided on the second inclined surface 7b of the storage protrusion 7 of the lower case 3 at an incline substantially parallel to the second inclined surface 7b, and is thus disposed at an incline with respect to the horizontal direction of the equipment case 1. Therefore, even if the length of the extension board 16 in the longitudinal direction of the equipment case 1 is long, the inclination of the extension board 16 with respect to the equipment case 1 keeps the longitudinal length of the equipment case 1 short.
[0038] 3 and 6 to 8, compared to a case where the extension substrate 16 is arranged along the longitudinal direction of the equipment case 1 and parallel to the horizontal direction of the equipment case 1, the horizontal length of the equipment case 1 becomes shorter according to the inclination of the extension substrate 16 arranged at an angle along the longitudinal direction of the equipment case 1. For this reason, the extension substrate 16 is designed to keep the longitudinal length of the equipment case 1 short even if the longitudinal length of the equipment case 1 is long.
[0039] On the other hand, as shown in Fig. 3 and Fig. 6 to Fig. 9, the extension lid 13 covers the extension storage recess 15 provided on the second inclined surface 7b of the storage protrusion 7 of the lower case 3, and protects the extension board 16 in the extension storage recess 15. This extension lid 13 includes a lid main body 18 and a waterproof panel 19, and is structured such that the waterproof panel 19 is attached to the inner surface of the lid main body 18 with a double-sided adhesive tape 20. As a result, the extension lid 13 is waterproofed by the waterproof panel 19, and the strength of the lid main body 18 is increased.
[0040] 3 and 6 to 9, the extension lid 13 is disposed in the extension storage recess 15 provided on the second inclined surface 7b of the storage protrusion 7 of the lower case 3, and is disposed substantially parallel to the second inclined surface 7b, and is thus disposed at an incline with respect to the horizontal direction of the device case 1, similar to the extension board 16. Therefore, even if the length of the extension lid 13 in the longitudinal direction of the device case 1 is long, the inclination of the extension lid 13 with respect to the device case 1 keeps the longitudinal length of the device case 1 short.
[0041] 3 and 6 to 8, like the extension board 16, the extension lid 13 has a shorter horizontal length of the equipment case 1 in accordance with the inclination of the extension lid 13 arranged at an angle along the longitudinal direction of the equipment case 1, compared to a case in which the extension lid 13 is arranged parallel to the horizontal direction of the equipment case 1 along the longitudinal direction of the equipment case 1. For this reason, the extension lid 13 is designed to keep the longitudinal length of the equipment case 1 short even if the longitudinal length of the equipment case 1 is long.
[0042] As shown in Figs. 6 to 9, the lid body 18 is formed in a substantially flat plate shape with an outer circumferential shape the same size as the inner circumferential shape of the expansion storage recess 15. On both sides of the lid body 18 in the short side direction of the equipment case 1, mounting protrusions 18a are provided protruding laterally. Each of the mounting protrusions 18a is provided with screw insertion holes 18b into which the mounting screws 21 are inserted, substantially perpendicular to the horizontal direction of the equipment case 1. Each of the screw insertion holes 18b has a large diameter hole portion into which the head 21a of the mounting screw 21 is inserted, and a small diameter hole portion into which the threaded portion 21b of the mounting screw 21 is inserted.
[0043] In this case, on both sides in the short direction of the device case 1 in the expansion storage recess 15, i.e., on both sides in the short direction of the device case 1 in the second inclined surface 7b of the storage protrusion 7, cutout portions 22 in which the mounting protrusions 18a of the lid main body 18 are disposed are provided, as shown in Fig. 5 and Fig. 8. As a result, when the lid main body 18 is disposed in the expansion storage recess 15 and the mounting protrusions 18a are disposed in the cutout portions 22, the extension lid 13 is disposed at an angle relative to the device case 1 in a state substantially parallel to the second inclined surface 7b of the storage protrusion 7.
[0044] 8, each of these cutout portions 22 has a vertical surface 22a that is provided substantially perpendicular to the horizontal direction of the device case 1, and a horizontal surface 22b that is provided substantially parallel to the horizontal direction of the device case 1. A screw hole 22c into which the threaded portion 21b of the mounting screw 21 screws is provided on each horizontal surface 22b of the cutout portions 22 substantially perpendicular to the horizontal surface 22b.
[0045] As a result, as shown in Figures 6 to 9, when the lid body 18 is placed in the expanded storage recess 15 and the mounting protrusion 18a is placed in the cutout portion 22, the expandable lid 13 is configured so that the screw insertion hole 18b of the mounting protrusion 18a corresponds coaxially to the screw hole 22c of the cutout portion 22 provided in the second inclined surface 7b of the storage convex portion 7.
[0046] For this reason, as shown in Figures 6 to 9, the expandable lid 13 is configured such that the mounting protrusion 18a is positioned in the cutout portion 22, and the screw insertion hole 18b of the mounting protrusion 18a corresponds coaxially to the screw hole 22c of the cutout portion 22 provided in the second inclined surface 7b of the storage convex portion 7, and the mounting screw 21 is inserted into the screw insertion hole 18b of the mounting protrusion 18a approximately perpendicular to the horizontal direction of the equipment case 1, and the threaded portion 21b of the mounting screw 21 is screwed into the screw hole 22c of the cutout portion 22, thereby attaching the lid body 18 to the expanded storage recess 15.
[0047] In addition, a pair of notches 22 provided on both sides of the second inclined surface 7b of the storage protrusion 7 make it easier to grasp both sides of the extension substrate 16 with the fingertips when placing the extension substrate 16 in the extension storage recess 15 or when removing the extension substrate 16 from the extension storage recess 15 when the extension lid 13 is removed from the extension storage recess 15 of the storage protrusion 7, as shown in Figures 5 and 8.
[0048] That is, as shown in Figures 6 to 8, these pair of cutout portions 22 are configured so that the fingertips of a hand grasping both sides of the extension board 16 are positioned when the fingers of the hand grasp both sides of the extension board 16 and insert the board connector 16a of the extension board 16 into the extension connector 17 in the extension storage recess 15, or when removing the board connector 16a of the extension board 16 from the extension connector 17 in the extension storage recess 15.
[0049] That is, as shown in Figures 6 to 8, the pair of cutout portions 22 are configured so that the fingertips of the hand grasping both sides of the extension board 16 are positioned across both external sides in the short side direction of the equipment case 1 and inside the extended storage recess 15, thereby preventing the fingertips of the hand grasping both sides of the extension board 16 from being obstructed by both external sides in the short side direction of the equipment case 1.
[0050] 6 to 9, the lid body 18 is provided with a lid packing retainer 18c in a frame shape on the outer periphery of the inner surface. This lid packing retainer 18c is configured to press the lid packing 23 arranged along the inner periphery of the expansion storage recess 15 provided on the second inclined surface 7b of the storage protrusion 7. In this case, a lid mounting groove 15b in which the lid packing 23 is attached is provided along the entire periphery on the inner periphery at the bottom of the expansion storage recess 15, and the lid packing 23 is arranged in the lid mounting groove 15b in a state where it is exposed upward.
[0051] As a result, as shown in Figures 6 to 9, when the lid body 18 is attached to the expanding storage recess 15 with the mounting screws 21, the lid gasket pressing portion 18c presses the lid gasket 23 mounted in the lid mounting groove 15b provided on the inner circumference at the bottom of the expanding storage recess 15, thereby waterproofing the expanding storage recess 15.
[0052] 5 and 9, the lid body 18 is provided with a metal fitting attachment section 24 to which the first belt mounting bracket 14 is slidably attached. In this case, the first belt mounting bracket 14 is formed by bending a metal plate into a U-shape. The upper plate 14a of the first belt mounting bracket 14 is provided with a second belt mounting hole 14c through which one end 12a of the hand belt 12 is inserted and attached, and the middle part of the lower plate 14b is provided with a metal fitting locking hole 14d.
[0053] 5, 8 and 9, the fitting mounting part 24 is provided with a pair of first pressing parts 25 that slidably press both sides of the first belt mounting fitting 14, and a second pressing part 26 that elastically presses the middle part of the first belt mounting fitting 14. The pair of first pressing parts 25 press both sides of the lower plate 14b of the first belt mounting fitting 14 toward the outer surface of the lid main body 18. In this case, the pair of first pressing parts 25 are provided within the sliding range of the lid main body 18 in which the first belt mounting fitting 14 slides along the longitudinal direction of the equipment case 1, i.e., the inclination direction of the second inclined surface 7b of the storage protrusion 7.
[0054] 5, 8 and 9, the pair of first pressing portions 25 include a pair of protruding portions 25a that protrude upward from both sides of the lid main body 18 in the short-side direction of the device case 1 and press down both sides of the bottom plate 14b, and a pair of pressing grooves 25b that are provided on the lower side of each of the pair of protruding portions 25a and correspond to both sides of the bottom plate 14b of the first belt mounting bracket 14. In this case, the pair of pressing grooves 25b are provided penetrating the front and back surfaces of the lid main body 18 in the thickness direction, except for the upper ends of the pair of protruding portions 25a.
[0055] 5, 8 and 9, the second pressing portion 26 is provided in a tongue shape in the center of the lid main body 18 along the inclination direction of the second inclined surface 7b of the storage protrusion 7. That is, the second pressing portion 26 is configured to bend and deform in the thickness direction, i.e., the up-down direction, of the lid main body 18 by providing a slit hole 26a around the periphery of the tongue shape except for the base portion which is one end. An engagement protrusion 26b that releasably engages with the metal fitting engagement hole 14d of the lower plate 14b of the first belt mounting metal fitting 14 is provided on the tip of the second pressing portion 26.
[0056] As a result, as shown in Figures 5, 8 and 9, when the lower plate 14b of the first belt mounting bracket 14 is placed on the outer surface of the lid main body 18 and slid toward the base of the second inclined surface 7b of the storage protrusion 7, both side portions of the lower plate 14b are inserted into the respective undersides of the pair of first pressing portions 25, and the middle portion of the lower plate 14b presses down on the engaging projection 26b of the second pressing portion 26, causing the second pressing portion 26 to bend downward.
[0057] Furthermore, as shown in Figures 5, 8 and 9, when the lower plate 14b slides over the outer surface of the lid main body 18 and both side portions of the lower plate 14b are pressed against the lid main body 18 in correspondence with each of the pressing grooves 25b of the pair of first pressing portions 25.
[0058] Furthermore, as shown in Figures 5, 8 and 9, when both side portions of the lower plate 14b are pressed against the lid body 18, the second pressing portion 26, which has been flexed and deformed by the middle portion of the lower plate 14b, elastically returns to its original state, and the engaging protrusion 26b of the second pressing portion 26 elastically engages with the metal fitting engagement hole 14d of the lower plate 14b, thereby attaching the first belt mounting bracket 14 to the lid body 18.
[0059] 5 to 9, a lid protection part 27 that reinforces the lid main body 18 is provided on the outer surface of the lid main body 18 and protrudes in a frame shape. That is, the lid protection part 27 surrounds the metal fitting attachment part 24 and is provided along the outer periphery of the area that surrounds the sliding range of the first belt mounting bracket 14. As a result, the lid protection part 27 is configured to reinforce the strength of the thin parts of the lid main body 18, i.e., the metal fitting attachment part 24.
[0060] That is, as shown in Figures 5 to 9, when the expandable storage recess 15 is formed large in the device case 1, the lid body 18 also becomes large accordingly, and the strength of the entire lid body 18 decreases, so it is necessary to increase the thickness of the lid body 18. However, this lid body 18 is configured such that the strength of the lid body 18 is ensured by the lid protection part 27 even if the thickness of the lid body 18 is reduced, because the periphery of the metal fitting attachment part 24 is reinforced by the lid protection part 27.
[0061] 5 to 9, the lid body 18 has the lid protection part 27 provided in a frame-like protruding manner on the outer surface of the lid body 18, so that even if the lid protection part 27 is provided on the lid body 18, the lid protection part 27 does not protrude into the expanded storage recess 15. Therefore, the internal space of the expanded storage recess 15 is not restricted by the lid protection part 27, and the internal volume of the expanded storage recess 15 is secured, allowing for high-density storage.
[0062] 9, the waterproof panel 19 is for waterproofing the lid body 18, and is attached to the inner surface, i.e., the underside, of the lid body 18 with a double-sided adhesive tape 20. As a result, even if the pressing grooves 25b of the pair of first pressing parts 25 provided on the lid body 18 and the slit holes 26a of the second pressing parts 26 penetrate through to the front and back surfaces of the lid body 18, the waterproof panel 19 closes the pressing grooves 25b of the pair of first pressing parts 25 and the slit holes 26a of the second pressing parts 26, thereby achieving waterproofing and increasing the strength of the lid body 18.
[0063] In this case, the waterproof panel 19 is provided with an escape recess 19a that allows for flexural deformation of the second pressing portion 26 of the metal fitting attachment portion 24, as shown in Figures 6, 7 and 9. This escape recess 19a is provided on the waterproof panel 19 relative to the second pressing portion 26 in a shape that corresponds to the flexural deformation of the second pressing portion 26, that is, inclined so that the tip side of the second pressing portion 26 is deep and the base side of the second pressing portion 26 is shallow. For this reason, the escape recess 19a is provided protruding in an inclined state on the lower side of the waterproof panel 19.
[0064] 5, 11, and 12, the storage protrusion 7 to which the extension lid 13 is attached is provided with legs 28 for supporting the device case 1. The legs 28 are provided on both sides in the short direction of the device case 1 at the top of the second inclined surface 7b of the storage protrusion 7. As a result, when the lower case 3 is placed on a placement surface such as a table, the device case 1 is configured to be supported at three points: the legs 28 provided on both sides of the storage protrusion 7 and a part of the lower case 3 on the other end 1b side of the device case 1.
[0065] In this case, each corner on both sides of the second inclined surface 7b of the storage protrusion 7 in the short-side direction of the device case 1 is formed into an arc-shaped curved surface 7f as shown in Fig. 5. The legs 28 are provided on the curved surfaces 7f of each corner on both sides of the second inclined surface 7b. That is, the legs 28 protrude from three surfaces: the second inclined surface 7b of the storage protrusion 7, the side surface 7d of the storage protrusion 7 in the short-side direction of the device case 1, and the convex surface 7e on the top side of the second inclined surface 7b.
[0066] As shown in Fig. 13, the leg 28 includes a soft member 29 having elasticity such as elastomer or rubber, and a hard member 30 made of a material harder than the soft member 29 and fixed to the storage protrusion 7 of the lower case 3. As shown in Fig. 5, the soft member 29 is an anti-slip member that prevents the device from slipping when placed on a placement surface such as a table. The soft member 29 is configured to be arranged so as to protrude from three surfaces: the second inclined surface 7b of the storage protrusion 7, a side surface 7d of the storage protrusion 7 in the short direction of the device case 1, and a convex surface 7e on the top side of the second inclined surface 7b.
[0067] 13, the hard member 30 includes a mounting portion 30a on which the soft member 29 is provided, and a fixed shaft 30b that is provided on the underside of the mounting portion 30a and is inserted into a leg attachment hole 31 provided in the storage protrusion 7. The mounting portion 30a is provided at an angle with respect to the fixed shaft 30b.
[0068] That is, as shown in Figures 5, 11, and 12, the mounting portion 30a is arranged on three surfaces: the second inclined surface 7b of the storage protrusion 7, the side surface 7d of the storage protrusion 7 in the short direction of the equipment case 1, and the convex surface 7e on the top side of the second inclined surface 7b, and is configured to be arranged inclined in two directions: the inclination direction of the second inclined surface 7b and the direction of the side surface 7d of the storage protrusion 7.
[0069] As shown in Fig. 5 and Fig. 11 to Fig. 13, the fixed shaft 30b is provided in a direction substantially perpendicular to the horizontal plane of the equipment case 1. This fixed shaft 30b is inserted into the leg mounting hole 31 of the storage protrusion 7, and a fusion portion 30c is provided in a portion protruding from the leg mounting hole 31 into the inside of the storage protrusion 7. Thus, as shown by the two-dot chain line in Fig. 11 and Fig. 12, the fixed shaft 30b is configured such that the fusion portion 30c protruding from the leg mounting hole 31 into the inside of the storage protrusion 7 is melted, and the fixed shaft 30b is fixed to the storage protrusion 7 by the fusion portion 30c.
[0070] In this case, as shown in Figures 11 and 12, the joint surface between the soft member 29 and the mounting portion 30a of the hard member 30 is provided with uneven portions 29a and 30d that allow the soft member 29 and the mounting portion 30a of the hard member 30 to bite into each other. The soft member 29 is formed integrally with the mounting portion 30a of the hard member 30 by insert molding. In this case, when the soft member 29 is provided on the mounting portion 30a of the hard member 30 by insert molding, the uneven portions 29a and 30d bite into each other and are firmly fixed.
[0071] On the other hand, the storage protrusion 7 of the lower case 3 is provided with a pair of third belt attachment holes 32 for attaching a predetermined member, for example, a hand belt 12 or a strap (not shown), as shown in Figs. 14 to 16. The pair of third belt attachment holes 32 are provided on both sides in a short direction perpendicular to the longitudinal direction of the device case 1 on the second inclined surface 7b of the storage protrusion 7. The pair of third belt attachment holes 32 are provided in communication with two surfaces of the storage protrusion 7, namely, the side surface 7d in the short direction of the device case 1 and the second inclined surface 7b.
[0072] That is, as shown in Figures 14 to 16, the pair of third belt mounting holes 32 include a first mounting hole 32a provided on the second inclined surface 7b side and a second mounting hole 32b provided on the side surface 7d of the storage protrusion 7 in the short direction of the equipment case 1, and are configured so that the innermost portion of the first mounting hole 32a and the innermost portion of the second mounting hole 32b are connected and communicate with each other.
[0073] The pair of third belt attachment holes 32 are provided as strap holes for attaching straps (not shown), and also as holes for attaching the hand belt 12, as shown in Figures 14 to 16. In this case, the pair of third belt attachment holes 32 are configured so that second belt attachment fittings 33 for attaching the hand belt 12 can be detachably attached thereto.
[0074] As shown in Figures 14 to 16, the second belt mounting metal fitting 33 comprises a metal fitting body 34 to which the hand belt 12 is attached, and a pair of metal fitting attachment parts 35 bent at both ends of the metal fitting body 34. The metal fitting body 34 is formed in a rectangular bar with a cover part 34a provided on its outer circumferential surface. The metal fitting body 34 is formed to have a length substantially equal to the distance between the pair of third belt mounting holes 32.
[0075] As shown in Figures 14 to 16, the pair of metal fitting attachment portions 35 are configured to be removably inserted from above and attached into each of the first attachment holes 32a of a pair of third belt attachment holes 32 provided on both sides of the second inclined surface 7b of the storage convex portion 7 in a short direction perpendicular to the longitudinal direction of the equipment case 1.
[0076] 14 to 16, the pair of metal fitting attachment parts 35 are provided with cut grooves 35a extending from the lower end to the upper part along the longitudinal direction of the device case 1 at the intermediate part in the lateral direction of the device case 1 on the second inclined surface 7b of the storage protrusion 7. As a result, when the pair of metal fitting attachment parts 35 are inserted into the first mounting holes 32a of the pair of third belt mounting holes 32 from the second inclined surface 7b side of the storage protrusion 7, the cut grooves 35a cause the pair of metal fitting attachment parts 35 to flex and deform in the lateral direction of the device case 1 on the second inclined surface 7b of the storage protrusion 7.
[0077] In addition, as shown in Figures 14 to 16, the pair of metal fitting attachment portions 35 are provided on each outer surface of the second inclined surface 7b of the storage protrusion 7 in the short direction of the equipment case 1 with engagement protrusions 35b that releasably engage with each second mounting hole 32b of a pair of third belt mounting holes 32 that communicate with the side surface 7d of the storage protrusion 7 in the short direction of the equipment case 1.
[0078] As a result, when the pair of metal fitting attachment portions 35 are inserted into each of the first mounting holes 32a of the pair of third belt mounting holes 32 from the second inclined surface 7b side of the storage convex portion 7, as shown in Figures 14 to 16, the bent and deformed pair of metal fitting attachment portions 35 elastically return to their original state in the expanding direction, and the engagement protrusions 35b are configured to releasably engage with each of the second mounting holes 32b of the pair of third belt mounting holes 32.
[0079] As shown in Figures 14 to 16, when releasing the engagement of the engagement protrusions 35b with each of the second mounting holes 32b of the pair of third belt mounting holes 32, the pair of metal fitting attachment portions 35 are configured to be removed from the third belt mounting hole 32 by inserting a tool into the second mounting hole 32b from the short side surface 7d of the device case 1 at the storage convex portion 7 and using this tool to press the engagement protrusions 35b to flexibly deform the metal fitting attachment portions 35 and disengage the engagement protrusions 35b from the second mounting holes 32b.
[0080] On the other hand, each of the pair of third belt mounting holes 32 is designed to allow a strap to be individually attached to the pair of third belt mounting holes 32 by inserting a string of a strap (not shown) from one side of the first mounting hole 32a to the other side of the second mounting hole 32b.
[0081] 17 and 18, the upper case 2 of the device case 1 includes a case body 36 which is a reinforcing member formed of a highly rigid material, and an outer circumferential cover 37 made of synthetic resin and provided to cover the outer circumferential edge and the underside of the case body 36. The case body 36 is formed in a substantially flat plate shape from a highly rigid material, for example, a metal such as a magnesium alloy, stainless steel, or aluminum alloy, or a reinforced plastic, or a material made by weaving and solidifying carbon fiber or glass fiber.
[0082] As shown in Fig. 17 and Fig. 18, the case body 36 includes a first reinforcing part 38, which is a second extending part extending from the outer periphery of the case body 36 and having a thickness greater than that of the case body 36, a second reinforcing part 39, which is a first extending part provided so as to protrude in a frame shape from the lower surface of the first reinforcing part 38 along the outer periphery of the case body 36, and a joint part 36a where the first reinforcing part 38 and the second reinforcing part 39 are joined. The joint part 36a is formed to be thicker than the first reinforcing member. The outer periphery cover part 37 is provided to cover the outer periphery and lower surface of the case body 36, that is, the first reinforcing part 38, the second reinforcing part 39, the joint part 36a, and the lower surface of the case body 36.
[0083] In this case, the first reinforcing portion 38 and the second reinforcing portion 39 are formed to have a T-shaped cross section as shown in Figures 17 and 18. This increases the overall rigidity of the first reinforcing portion 38 and the second reinforcing portion 39, ensuring strength, and allowing the first reinforcing portion 38 and the second reinforcing portion 39 to maintain a high pressing force without succumbing to the elasticity of the waterproof packing 42 described below, thereby ensuring high waterproofness.
[0084] 17 and 18, a mountain-shaped protective protrusion 38a protruding upward is provided on the outer peripheral end of the first reinforcing portion 38, i.e., the outer peripheral end of the joint portion 36a. This protective protrusion 38a protects the outer periphery of the input display unit 4 arranged on the case main body 36. The first reinforcing portion 38 is arranged so that the lower surface of the protective protrusion 38a corresponds to the outer peripheral edge of the lower case 3. Furthermore, the first reinforcing portion 38 is provided with a step portion 38b at the boundary with the case main body 36 that is exposed and not covered by the outer periphery cover portion 37.
[0085] 17 and 18, outer periphery cover portion 37 is configured so that when upper case 2 is attached to lower case 3 in an overlapping state, the outer periphery of outer periphery cover portion 37 is disposed in close contact with the upper surface and inner periphery of the outer periphery of lower case 3. On outer periphery cover portion 37, packing retainer rib 37a, which is a packing retainer portion corresponding to second reinforcing portion 39, is provided in a frame shape protruding toward lower case 3.
[0086] On the other hand, a case packing groove 41 is provided along the inner peripheral surface of the lower case 3, as shown in Figures 17 and 18. A waterproof packing 42 is disposed in this case packing groove 41. With this, the device case 1 is configured such that, when the upper case 2 is attached to the lower case 3 by overlapping them, the packing retaining rib 37a of the outer periphery cover portion 37 is pressed into the case packing groove 41 of the lower case 3 by the second reinforcing portion 39, thereby retaining the waterproof packing 42.
[0087] That is, as shown in Figures 17 and 18, when the upper case 2 is pressed against the lower case 3, the second reinforcing portion 39 provided on the case main body portion 36 of the upper case 2 presses down the packing retaining rib 37a of the outer cover portion 37 and forces it into the case packing groove 41 of the lower case 3, and this pressed packing retaining rib 37a presses the waterproof packing 42 in the packing groove 41 of the lower case 3.
[0088] In addition, as shown in Figures 17 and 18, when the waterproof gasket 42 in the case gasket groove 41 is pressed by the gasket pressing rib 37a, the outer peripheral surface of the outer cover portion 37 is positioned in close contact with the upper surface and inner peripheral surface of the outer peripheral edge of the lower case 3.
[0089] Next, the operation of such a portable terminal will be described. First, the manufacturing method of the upper case 2 will be described with reference to Fig. 19. The manufacturing method of the upper case 2 includes a first step of forming the case main body 36, which is a reinforcing member, from a highly rigid material, a second step of fixing the case main body 36 in a molding die 45, and a third step of injecting resin into the molding die 45 to form the outer periphery cover 37 on the case main body 36.
[0090] In the first step, the case body 36 is formed into a substantially flat plate shape using a highly rigid material such as a metal such as a magnesium alloy, stainless steel, or aluminum alloy, or a reinforced plastic, or a material made by weaving and solidifying carbon fiber or glass fiber. At this time, a thick first reinforcing part 38 extending from the outer periphery of the case body 36 and a second reinforcing part 39 provided on the first reinforcing part 38 are formed.
[0091] In this case, a mountain-shaped protective protrusion 38a that protects the outer periphery of the input display unit 4 is provided at the outer peripheral end of the first reinforcing portion 38, protruding upward (lower side in FIG. 19). Also, at the boundary between the first reinforcing portion 38 and the case main body 36, a step portion 38b is provided above (lower side in FIG. 19) the upper surface (lower surface in FIG. 19) of the case main body 36.
[0092] In the second step, the case body 36 is placed in the molding die 45. The molding die 45 includes a lower die 46 and an upper die 47. When placing the case body 36 in the molding die 45, it is placed inside the lower die 46 and the upper die 47. At this time, the fitting protrusion 46a, which is a part of the lower die 46, is fitted between the step portion 38b of the first reinforcing portion 38 located at the boundary with the case body 36, and the outer peripheral surface of the fitting protrusion 46a is pressed against the inner peripheral surface of the step portion 38b. This restricts the position of the case body 36 relative to the lower die 46, and the case body 36 is fixed in the molding die 45.
[0093] In this state, a molding space (cavity) 48 for the outer periphery cover portion 37 is formed in the molding die 45. This molding space 48 has a first space 48a surrounding each outer periphery of the first reinforcing portion 38 and the second reinforcing portion 39 with a predetermined gap therebetween, a groove-shaped second space 48b corresponding to the same axis as the second reinforcing portion 39 below the second reinforcing portion 39 (upper side in FIG. 19), and a third space 48c corresponding to the lower side of the case main body portion 36 (upper side in FIG. 19).
[0094] In the third step, resin is injected into the molding space 48 of the molding die 45 and cured. Then, the first space 48a of the molding space 48 integrally forms the outer periphery cover portion 37 on each outer periphery of the first reinforcing portion 38 and the second reinforcing portion 39 of the case body portion 36. At this time, the second space 48b of the molding space 48 forms the packing retainer rib 37a of the outer periphery cover portion 37 on the lower side of the second reinforcing portion 39 in correspondence with the second reinforcing portion 39. Also, at this time, the third space 48c of the molding space 48 forms the outer periphery cover portion 37 on the lower side of the case body portion 36.
[0095] Thereafter, the lower die 46 and the upper die 47 of the molding die 45 are released, and the molded upper case 2 is removed from the molding die 45. In this state, the step portion 38b of the first reinforcing portion 38 located at the boundary with the case main body 36 is exposed without being covered by the outer periphery cover portion 37. As a result, the upper case 2 in which the outer periphery cover portion 37 is provided on the outer periphery of the case main body 36 is obtained.
[0096] Next, a case where the upper case 2 thus manufactured is placed on the lower case 3 to form the device case 1 will be described. 17 and 18, first, waterproof packing 42 is placed in packing groove 41 of lower case 3 provided along the inner peripheral surface of lower case 3. Then, lower case 3 is placed on upper case 2 so that packing retainer rib 37a of outer peripheral cover portion 37 of upper case 2 corresponds to packing groove 41 of lower case 3.
[0097] In this state, the lower case 3 is pressed against the upper case 2. Then, the packing retainer rib 37a of the outer periphery cover portion 37 of the upper case 2 is pressed into the packing groove 41 of the lower case 3 by the second reinforcing portion 39 of the upper case 2. This pressed-in packing retainer rib 37a presses the waterproof packing 42 in the packing groove 41. This ensures that the upper case 2 and the lower case 3 are waterproofed. At this time, the outer periphery surface of the outer periphery cover portion 37 is disposed in close contact with the upper surface and inner periphery surface of the outer periphery edge of the lower case 3. In this way, the device case 1 is assembled.
[0098] In this case, before assembling the device case 1, various parts are attached to the upper case 2 in advance. That is, the input display unit 4 and the key input unit 5 are attached to the surface of the upper case 2. In this case, the input display unit 4 is attached to the upper case 2 in advance by laminating a transparent touch panel 4b on the display panel 4a. Also, the key input unit 5 is attached to the upper case 2 in advance by arranging a plurality of key buttons 5a on the switch board 5b.
[0099] Furthermore, the circuit board 6 is attached in correspondence with the input display unit 4, and the unit case 9a of the optical reading unit 9 is also attached inside the upper case 2. At this time, a scanner unit 9b equipped with a laser reading unit and a camera unit, and an expansion connector 17 are attached in advance to the unit case 9a. Also, a connection electrode unit 11 is attached to the end of the upper case 2 on the other end 1b side in the longitudinal direction of the device case 1.
[0100] Furthermore, a side trigger key 1c is attached to the side of the upper case 2. In this state, the input display unit 4, the switch board 5b of the key input unit 5, the scanner unit 9b, the expansion connector 17, the connection electrode unit 11, and the side trigger key 1c are each electrically connected to the circuit board 6. In this way, various parts are assembled to the upper case 2.
[0101] Meanwhile, various parts are also assembled in the lower case 3. That is, the optical window portion 7c is attached to the first inclined surface 7a of the storage protrusion 7. In this state, the upper case 2 is attached to the lower case 3 in a superimposed manner as described above to assemble the device case 1. Then, the scanner portion 9b provided in the unit case 9a of the optical reading portion 9 provided in the upper case 2 corresponds to the optical window portion 7c provided in the first inclined surface 7a of the storage protrusion 7 of the lower case 3.
[0102] At this time, the expansion connector 17 provided on the unit case 9a is inserted into the opening 15a at the bottom of the expansion storage recess 15 provided on the second inclined surface 7b of the storage protrusion 7 and is exposed inside the expansion storage recess 15. In this case, the bottom of the expansion storage recess 15 is arranged at an incline substantially parallel to the second inclined surface 7b of the storage protrusion 7. The expansion connector 17 exposed and arranged inside the expansion storage recess 15 is arranged inside the expansion storage recess 15 at an incline substantially parallel to the second inclined surface 7b of the storage protrusion 7 and is arranged at an incline with respect to the horizontal direction of the device case 1.
[0103] In this state, the extension board 16 is placed in the expansion storage recess 15. At this time, the board connector 16a provided on the underside of the extension board 16 is inserted into the expansion connector 17 exposed in the expansion storage recess 15, and the extension board 16 is attached by being electrically connected to the expansion connector 17. In this state, the extension board 16 is placed in the expansion storage recess 15 at an angle substantially parallel to the second inclined surface 7b of the storage protrusion 7.
[0104] Therefore, the inclination of the extension substrate 16 with respect to the device case 1 keeps the length of the device case 1 short. That is, when the extension substrate 16 is arranged at an incline along the longitudinal direction of the device case 1, the horizontal length of the device case 1 becomes shorter according to the inclination of the extension substrate 16 compared to when the extension substrate 16 is arranged parallel to the horizontal direction of the device case 1 along the longitudinal direction of the device case 1. Therefore, the length of the extension substrate 16 in the longitudinal direction of the device case 1 is kept short even if the longitudinal length of the device case 1 is long.
[0105] In this case, since the expansion connector 17 is arranged long in the short direction of the equipment case 1 within the expansion storage recess 15, when grasping both sides of the expansion board 16 in the short direction of the equipment case 1 with the fingertips and inserting the board connector 16a of the expansion board 16 into the expansion connector 17, the expansion board 16 can be easily tilted in the short direction of the equipment case 1, so that the board connector 16a of the expansion board 16 can be easily and satisfactorily inserted into the expansion connector 17.
[0106] In addition, when grasping both sides of the extension board 16 in the short direction of the equipment case 1 with the fingertips and inserting the board connector 16a of the extension board 16 into the expansion connector 17, the fingertips of the hand grasping both sides of the extension board 16 are positioned in each of the cutout portions 22 provided on both sides of the equipment case 1 in the short direction on the second inclined surface 7b of the storage convex portion 7, which also makes it possible to easily and satisfactorily insert the board connector 16a of the extension board 16 into the expansion connector 17.
[0107] Then, the extension lid 13 is attached to the extension storage recess 15 to protect the extension board 16. At this time, the extension lid 13 is assembled in advance. In this case, a waterproof panel 19 is attached to the inner surface of the lid body 18 of the extension lid 13 with double-sided adhesive tape 20. This makes the extension lid 13 waterproof by the waterproof panel 19, and the extension lid 13 is assembled with the lid body 18 having increased strength.
[0108] When attaching the expandable lid 13 to the expandable storage recess 15, first, the lid gasket 23 is attached to the lid attachment groove 15b provided on the inner peripheral surface of the expandable storage recess 15, and in this state, the expandable lid 13 is attached to the expandable storage recess 15. At this time, the lid gasket pressing portion 18c of the expandable lid 13 presses the lid gasket 23 attached to the lid attachment groove 15b of the expandable storage recess 15, thereby waterproofing the expandable lid 13 and the expandable storage recess 15.
[0109] In this case, the mounting protrusions 18a protruding from both sides of the lid body 18 in the short direction of the equipment case 1 are placed in the notches 22 provided on both sides of the second inclined surface 7b of the storage protrusion 7 in the short direction of the equipment case 1. At this time, the mounting protrusions 18a of the extendable lid 13 are placed on the horizontal surface 22b of the notch 22 and abut against the vertical surface 22a of the notch 22. This allows the extendable lid 13 to be accurately and satisfactorily placed in the extendable storage recess 15.
[0110] In this state, the screw insertion hole 18b provided in the mounting protrusion 18a corresponds coaxially to the screw hole 22c provided in the horizontal surface 22b of the cutout portion 22. Therefore, the mounting screw 21 is inserted into the screw insertion hole 18b of the mounting protrusion 18a approximately perpendicular to the horizontal direction of the device case 1, and the threaded portion 21b of the mounting screw 21 is screwed into the screw hole 22c of the cutout portion 22 and tightened.
[0111] As a result, the lid packing retainer 18c of the extension lid 13 presses the lid packing 23 attached to the lid attachment groove 15b of the extension storage recess 15, the lid body 18 closes the extension storage recess 15, and the extension lid 13 is attached to the extension storage recess 15. When the extension lid 13 is attached to the extension storage recess 15 in this manner, the extension lid 13 is disposed in the extension storage recess 15 at an incline substantially parallel to the second inclined surface 7b of the storage protrusion 7. For this reason, like the extension board 16, the inclination of the extension lid 13 relative to the device case 1 keeps the longitudinal length of the device case 1 short.
[0112] That is, when the extension lid 13 is arranged at an angle along the longitudinal direction of the equipment case 1, the horizontal length of the equipment case 1 becomes shorter according to the angle of the extension lid 13 compared to when the extension lid 13 is arranged parallel to the horizontal direction of the equipment case 1 along the longitudinal direction of the equipment case 1, similar to the extension board 16. Therefore, even if the longitudinal length of the equipment case 1 is long, the longitudinal length of the equipment case 1 can be kept short with the extension lid 13.
[0113] Then, the battery pack B is stored in the battery storage section 3a in the lower case 3, and the battery lid 8 is attached to the battery storage section 3a. At this time, the other end 8d of the battery lid 8 is engaged with the edge of the battery storage section 3a on the other end 1b side of the device case 1, and one end 8c of the battery lid 8 is placed on the edge of the battery storage section 3a on the storage protrusion 7 side, and in this state, one end 8c of the battery lid 8 is locked with the lock lever 10.
[0114] That is, when one end 8c of the battery cover 8 is locked with the lock lever 10, in a state in which the battery cover 8 covers the battery storage section 3a of the lower case 3 and is placed in the lower case 3, the lever portion 10b of the lock lever 10 is swung within the lever storage recess 3b of the lower case 3 to rotate the lock portion 10a in one direction. Then, the lock portion 10a presses the one end 8c of the battery cover 8 against the edge of the battery storage section 3a to lock it. In this way, the mobile terminal is assembled.
[0115] Next, a case where this portable terminal is used will be described. In this case, the hand belt 12 is attached to the mobile terminal in advance. At this time, the first belt mounting bracket 14 is first attached to the extension lid 13. That is, the lower plate 14b of the first belt mounting bracket 14 is placed on the outer surface of the lid main body 18, and then slid toward the base side of the second inclined surface 7b of the storage protrusion 7.
[0116] Then, both side portions of the lower plate 14b of the first belt mounting bracket 14 are inserted into the underside of a pair of first pressing portions 25 on both sides of the metal fitting mounting portion 24 provided on the expansion lid 13, and the middle portion of the lower plate 14b of the first belt mounting bracket 14 presses down on the engaging protrusion 26b of the second pressing portion 26 of the metal fitting mounting portion 24, causing the second pressing portion 26 to bend downward.
[0117] In this state, when the lower plate 14b of the first belt mounting bracket 14 is further slid and both side portions of the lower plate 14b are pressed into the lower sides of the pair of first pressing portions 25, both side portions of the lower plate 14b are pressed against the lid main body 18 and correspond to the pressing grooves 25b of the pair of first pressing portions 25. At this time, the second pressing portion 26 that has been flexed and deformed by the middle portion of the lower plate 14b elastically returns to its original state, and the engaging projection 26b of the second pressing portion 26 elastically engages with the metal fitting locking hole 14d of the lower plate 14b. As a result, the first belt mounting bracket 14 is attached to the lid main body 18.
[0118] In this case, a lid protection portion 27 that reinforces the lid body 18 is provided on the outer surface of the lid body 18, surrounding the metal fitting mounting portion 24, and is also provided along the outer periphery of the area that surrounds the sliding range of the first belt mounting bracket 14, thereby reinforcing the strength of the thin part of the lid body 18, i.e., the metal fitting mounting portion 24.
[0119] For this reason, when the expandable storage recess 15 is formed large in the device case 1, the lid body 18 also becomes large accordingly, and the strength of the entire lid body 18 decreases, so it is necessary to increase the thickness of the lid body 18. However, since the periphery of the metal fitting mounting portion 24 of this lid body 18 is reinforced by the lid protection portion 27, the strength of the lid body 18 is ensured by the lid protection portion 27 even if the thickness of the lid body 18 is reduced.
[0120] In addition, since the lid protection part 27 of the lid body 18 is provided in a frame-like protruding manner on the outer surface of the lid body 18, even if the lid protection part 27 is provided on the lid body 18, the lid protection part 27 does not protrude into the expanded storage recess 15. Therefore, the internal space of the expanded storage recess 15 is not restricted by the lid protection part 27, and the internal volume of the expanded storage recess 15 is secured, allowing for high-density storage.
[0121] In this state, one end 12a of the hand belt 12 is inserted into and attached to a second belt attachment hole 14c provided in an upper plate 14a of the first belt attachment metal fitting 14. Also, the other end 12b of the hand belt 12 is attached to a first belt attachment hole 3c provided in the other end of the lower case 3 on the side of the other end 1b in the longitudinal direction of the device case 1. In this way, the hand belt 12 is attached to the mobile terminal.
[0122] When a user holds the mobile terminal in his / her hand to use, he / she first inserts his / her hand between the device case 1 and the hand belt 12 to grasp the device case 1. At this time, the fingers of the hand except for the thumb are inserted between the device case 1 and the hand belt 12, the thumb is placed on the input display unit 4 or the key input unit 5 of the device case 1, and the user grasps the device case 1 so as to wrap around the battery cover 8.
[0123] In this state, the user uses his / her thumb to perform an input operation 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, so the user can touch and operate the transparent touch panel 4b while viewing the information displayed on the display panel 4a.
[0124] In this state, when either the top trigger key 5c 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 a laser beam onto the product code of the product through the optical window 7c of the storage protrusion 7, and receives the reflected light to read the product code.
[0125] At this time, the camera unit of the scanner unit 9b captures an image of a subject such as a commodity, an article, or a two-dimensional code. As a result, the commodity code read by the laser reading unit is displayed on the input display unit 4 and is registered in the memory unit of the circuit board 6. Similarly, the subject such as a commodity, an article, or a two-dimensional code captured by the camera unit is displayed on the input display unit 4 and is registered in the memory unit of the circuit board 6.
[0126] In addition, when a card such as a credit card is brought close to the storage protrusion 7 of the lower case 3, the magnetic electrode 16b provided on the inner surface of the storage protrusion 7 captures the card information by a magnetic field (induced electromotive force), and this captured magnetic information signal is read as card information by the extension board 16. This read card information is also registered in the memory section of the circuit board 6.
[0127] Furthermore, when this mobile terminal is placed on a support surface such as a table, three points come into contact with the support surface: two legs 28 provided on both sides of the short side of the equipment case 1 at the storage protrusion 7 of the lower case 3, and a part of the lower case 3 on the other end 1b side of the equipment case 1, i.e., the other end 12b of the hand belt 12 attached to the end of the lower case 3.
[0128] As a result, the device case 1 is supported on the mounting surface at three points, so that the device case 1 is stably placed on the mounting surface. At this time, when the legs 28 provided on both sides of the storage protrusion 7 are placed on the mounting surface, the soft members 29 of the legs 28 are placed in contact with the mounting surface, so that the elasticity of the soft members 29 prevents the device case 1 from slipping on the mounting surface. This also ensures that the device case 1 is stably placed on the mounting surface.
[0129] In this case, since the soft members 29 of the legs 28 are formed of a resilient material such as elastomer or rubber, when the device case 1 is dropped or placed carelessly on the placement surface, the soft members 29 cushion the impact applied to the storage protrusion 7. As a result, the scanner unit 9b stored in the storage protrusion 7 is well protected from impact.
[0130] However, when an extension board larger than the extension board 16 is connected to the extension connector 17 in the extension storage recess 15 provided on the second inclined surface 7b of the storage protrusion 7 of the lower case 3, the extension lid 13 cannot be attached to the extension storage recess 15, and therefore it is necessary to use the device with the extension lid 13 removed. Therefore, the attachment position of the hand belt 12 with respect to the device case 1 must be changed.
[0131] In this case, one end 12a of the hand belt 12 is removed from the first belt mounting bracket 14. In this state, the second belt mounting bracket 33 is attached to a pair of third belt mounting holes 32 provided on both sides of the second inclined surface 7b of the storage protrusion 7 of the lower case 3 in the short direction perpendicular to the longitudinal direction of the device case 1.
[0132] At this time, a pair of metal fitting attachment parts 35 provided at both ends of the metal fitting main body 34 of the second belt mounting bracket 33 are inserted and attached into the first mounting holes 32a of the pair of third belt mounting holes 32. That is, when the pair of metal fitting attachment parts 35 are inserted into the first mounting holes 32a of the pair of third belt mounting holes 32 from the second inclined surface 7b side of the storage protrusion 7, the engagement projections 35b of the pair of metal fitting attachment parts 35 are pressed against the inner surfaces of the first mounting holes 32a of the pair of third belt mounting holes 32, so that the pair of metal fitting attachment parts 35 are flexibly deformed by the cut grooves 35a.
[0133] When the pair of metal fitting attachment parts 35 are inserted into the first attachment holes 32a of the pair of third belt attachment holes 32 from the second inclined surface 7b side of the storage protrusion 7, the flexibly deformed pair of metal fitting attachment parts 35 elastically return to their original position in the expanding direction, and the engaging projections 35b are inserted into the second attachment holes 32b of the pair of third belt attachment holes 32 to detachably engage with each other. As a result, the second belt attachment metal fittings 33 are attached to the pair of third belt attachment holes 32.
[0134] In this state, one end 12a of the hand belt 12 is inserted between the metal fitting body 34 of the second belt mounting metal fitting 33 and the second inclined surface 7b of the storage protrusion 7 of the lower case 3, and this inserted one end 12a of the hand belt 12 is folded back by the metal fitting body 34. In this case, one end 12a of the hand belt 12 is attached to the metal fitting body 34. In this case, the first belt mounting metal fitting 14 may be removed from the expansion lid 13, or may remain attached.
[0135] In this case, the user can also use the mobile terminal by holding it in his / her hand. That is, the user inserts his / her hand between the device case 1 and the hand belt 12 to grasp the device case 1. In this case, the user also inserts the fingers of the hand except for the thumb between the device case 1 and the hand belt 12, places the thumb on the input display unit 4 or the key input unit 5 of the device case 1, and grasps the device case 1 so as to wrap around the battery cover 8.
[0136] Furthermore, when carrying this mobile terminal, the hand belt 12 may be left attached to the device case 1, or may be removed from the device case 1. In this case, the second belt attachment metal fitting 33 may be removed from the pair of third belt attachment holes 32, and a strap (not shown) may be attached to one of the pair of third belt attachment holes 32. In this case, the string of the strap may be inserted from one of the first attachment hole 32a and the second attachment hole 32b in one of the pair of third belt attachment holes 32 to the other.
[0137] In this way, the case body 36, which is a reinforcing member of the upper case 2 in this mobile terminal, is embedded inside the upper case 2 in which the outer peripheral cover portion 37 is formed of a first material, and is formed of a second material having higher rigidity than the first material, and is provided with a second reinforcing portion 39 which is a first extension portion extending in the pressing direction of the packing retaining portion 37a provided at one end of the upper case 2, a first reinforcing portion 38 which is a second extension portion extending in a direction from one end of the upper case 2 toward the other end, perpendicular to the pressing direction, and a protective protrusion 38a which is provided at a joint 36a where the first reinforcing portion 38 and the second reinforcing portion 39 are joined so as to protrude toward the opposite side from the packing retaining portion 37a, thereby ensuring the strength and waterproofness of the outer periphery of the upper case 2.
[0138] In other words, in the upper case 2 of this equipment case 1, the first reinforcing portion 38 extended from the outer peripheral edge of the case main body portion 36, which is formed of a highly rigid material, is formed to be thicker than the case main body portion 36, and the joint portion 36a is formed to be thicker than the first reinforcing portion 38.Therefore, the first reinforcing portion 38 and the joint portion 36a can ensure the strength of the outer periphery of the upper case 2, and the second reinforcing portion 39 of the case main body portion 36 can firmly press the gasket retaining rib 37a of the outer periphery cover portion 37, thereby ensuring waterproofness.
[0139] In addition, in the upper case 2 of this equipment case 1, since the second reinforcing portion 39 is provided on the first reinforcing portion 38, the second reinforcing portion 39 can be firmly held by the first reinforcing portion 38, and therefore the second reinforcing portion 39 can press the gasket retaining rib 37a of the outer peripheral cover portion 37 even more firmly.
[0140] Furthermore, in the upper case 2 of this device case 1, a protective protrusion 38a is provided protruding upward from the outer periphery of the first reinforcing portion 38, so that when the input display portion 4 and the key input portion 5 are arranged on the case main body portion 36, the respective outer peripheries of the input display portion 4 and the key input portion 5 can be reliably and satisfactorily protected by the protective protrusion 38a of the first reinforcing portion 38.
[0141] Furthermore, in the upper case 2 of this equipment case 1, even if the first material is synthetic resin and the second material is magnesium alloy, and the outer cover portion 37 is formed from the first material, synthetic resin, the second material of the case main body 36, which is the reinforcing member, is formed from a magnesium alloy, so that the outer cover portion 37 can be reinforced by the first reinforcing portion 38, the second reinforcing portion 39, and the joint portion 36a of the case main body 36.
[0142] Furthermore, in the upper case 2 of this equipment case 1, a step portion 38b is provided at the boundary between the case main body portion 36 and the first reinforcing portion 38, which is exposed and not covered by the outer peripheral cover portion 37. Therefore, when the outer peripheral cover portion 37 is molded on the outer periphery of the case main body portion 36 using a molding die 45, the step portion 38a of the case main body portion 36 can accurately position and firmly fix the case main body portion 36 within the molding die 45.
[0143] In addition, according to the manufacturing method of the upper case 2, there are provided a first step of forming a case main body 36 made of a highly rigid material and having a thick first reinforcing portion 38 extending from the outer periphery and a second reinforcing portion 39 provided on this first reinforcing portion 38, a second step of fixing the case main body 36 within a molding die 45, and a third step of injecting resin into the molding die 45 to cover the first reinforcing portion 38 and the second reinforcing portion 39 around the outer periphery of the case main body 36 to form an outer periphery cover portion 37. As a result, the strength and waterproofness of the outer periphery of the upper case 2 can be ensured and the upper case 2 can be manufactured satisfactorily.
[0144] In other words, in the manufacturing method of the upper case 2, when the case main body portion 36 formed in the first step is fixed within the molding die 45 in the second step, a molding space 48 can be formed within the molding die 45 to correspond to the outer periphery of the case main body portion 36, i.e., the outer periphery of the first reinforcing portion 38 and the second reinforcing portion 39, and by injecting resin into the molding space 48 in the third step, the outer periphery cover portion 37 can be reliably and satisfactorily formed by covering the first reinforcing portion 38 and the second reinforcing portion 39 on the outer periphery of the case main body portion 36.
[0145] In this case, in the manufacturing method of the upper case 2, in the second step, the fitting protrusion 46a of the lower die 46, which is a part of the molding die 45, is fitted between the step portion 38a provided on the first reinforcing portion 38 located at the boundary between the case main body portion 36 and the first reinforcing portion 38, and the case main body portion 36 is fixed by restricting its position within the molding die 45, so that the case main body portion 36 can be accurately and reliably positioned within the molding die 45 and firmly fixed therein in the second step.
[0146] That is, in the manufacturing method of this upper case 2, when the fitting protrusion portion 46a of the lower mold 46 is fitted between the step portions 38a provided in the first reinforcing portion 38, the outer peripheral surface of the fitting protrusion portion 46a is pressed against the inner peripheral surface of the step portion 38a, and the fitting protrusion portion 46a of the lower mold 46 is fitted between the step portions 38a, so that the case main body portion 36 can be accurately and reliably positioned within the molding mold 45 and firmly fixed.
[0147] In the above embodiment, a single expansion connector 17 is provided in the expansion storage recess 15 provided in the second inclined surface 7b of the storage protrusion 7, but the present invention is not limited to this, and multiple expansion connectors may be arranged in an array. In this way, multiple expansion connectors can be used to expand more functions.
[0148] In addition, in the above-described embodiment, the extension board 16 is described as a card reading board that reads information on a card such as a credit card in a non-contact manner, but the present invention is not limited to this, and may be, for example, a sensor board equipped with a sensor such as a temperature sensor, a pressure sensor, or an infrared sensor, or may be a communication board equipped with a communication function.
[0149] Furthermore, in the above-described embodiment, the fixed shaft 30b of the hard member 30 of the leg 28 is fixed to the leg mounting hole 31 of the storage protrusion 7 by the welded portion 30c, but the present invention is not limited to this, and the fixed shaft 30b may be fixed to the leg mounting hole 31 of the storage protrusion 7 by, for example, a screw or a locking member such as an E-ring or a split pin.
