As a result, the hand belt 22 is attached to the rear surface of the device case 3 along the longitudinal direction of the device case 3 by having one end 22a attached to the belt mounting bracket 24 and the other end 22b attached to the belt mounting hole 3d.

[0026] On the other hand, the cradle 2 to which the mobile terminal 1 is attached, as shown in Figures 1, 2, 7 and 8, is equipped with a case attachment section 25 to which the other end 3b (the lower end in Figure 1) of the device case 3 of the mobile terminal 1 is attached, a pair of case support sections 26 that protrude upward from this case attachment section 25 and on which the back surface of the device case 3 is placed, and an auxiliary charging section 27 provided at the rear of the case attachment section 25.

[0027] 7 to 9, the case mounting section 25 is formed in a substantially box-like shape with a mounting recess 25a that holds the device case 3 at a slight tilt backward when the other end 3b of the device case 3 is mounted from above. In this case, the mounting recess 25a is formed shallow, with a vertical depth approximately equal to the longitudinal length of the device case 3 at a location on the other end 3b side of the device case 3 relative to the key input section 5.

[0028] 7 to 9, inside the case mounting section 25, i.e., below the mounting recess 25a, a cradle connection section 28 electrically connected to the connection electrode section 20 of the mobile terminal 1 is provided exposed within the mounting recess 25a. The cradle connection section 28 includes a plurality of contact pins 30, a plurality of leaf springs 31 each holding the plurality of contact pins 30, a support base 32 on which the plurality of leaf springs 31 are disposed, and a connection board 33 on which the support base 32 is disposed. In this case, the connection board 33 is fixed inside the case mounting section 25.

[0029] 8 and 9, one end of each of the plurality of leaf springs 31 is attached to a plurality of supports 32 arranged in parallel on a connection board 33, and the other end side is configured to bend and deform in the vertical direction with each support 32 as a fulcrum. Each of the plurality of contact pins 30 is provided upright on the other end of each of the plurality of leaf springs 31 located on the opposite side to the support 32.

[0030] 8 and 9, each of the contact pins 30 is formed in a cylindrical shape, and each tip 30a located at the upper end is formed in a hemispherical or curved shape. Each of the contact pins 30 is configured so that each tip 30a can protrude from each insertion hole 25b provided in the bottom of the mounting recess 25a of the case mounting part 25 so as to be able to enter and exit the mounting recess 25a.

[0031] As a result, as shown in Figures 8 and 9, the cradle connection portion 28 is configured so that when the device case 3 of the mobile terminal 1 is inserted into the mounting recess 25a of the case mounting portion 25 of the cradle 2, each tip 30a of the multiple contact pins 30 is elastically brought into contact with each electrode 20a of the connection electrode portion 20 provided at the end of the other end 3b of the mobile terminal 1.

[0032] That is, as shown in Figures 8 and 9, when the device case 3 of the mobile terminal 1 is pressed into the mounting recess 25a of the case mounting portion 25 of the cradle 2 and each electrode 20a of the connection electrode portion 20 of the mobile terminal 1 presses each tip 30a of the multiple contact pins 30, each leaf spring 31 is deflected downward and comes into contact with multiple board electrodes (not shown) provided on the connection board 33, thereby electrically connecting with the connection electrode portion 20 of the mobile terminal 1.

[0033] 7 to 9, a pair of spring members 35 are provided on both sides of the cradle connection portion 28 in the short side direction of the device case 3. Each of the pair of spring members 35 is configured to elastically support the other end portion 3b of the device case 3 located on both sides of the connection electrode portion 20 before the connection electrode portion 20 of the device case 3 of the mobile terminal 1 comes into contact with the cradle connection portion 28.

[0034] That is, as shown in Figures 7 to 9, these pair of spring members 35 are configured to elastically support the other end 3b of the device case 3 before the connection electrode portion 20 of the device case 3 comes into contact with the cradle connection portion 28, so that when the other end 3b of the device case 3 is pressed into the mounting recess 25a of the case mounting portion 25 of the cradle 2 against the spring force of the pair of spring members 35, each electrode 20a of the connection electrode portion 20 of the mobile terminal 1 comes into contact with each tip portion 30a of the multiple contact pins 30 at almost the same time.

[0035] 2, 7, and 8, the pair of case support parts 26 are provided to protrude upward from both sides of the case mounting part 25 in the short direction of the device case 3. That is, the pair of case support parts 26 are provided across both side parts and the rear part of the case mounting part 25 on both sides in the short direction of the device case 3. As a result, the pair of case support parts 26 are configured so that each side surface and each back surface on both sides in the short direction of the device case 3 of the mobile terminal 1 are arranged. In this case, the front side surfaces of the pair of case support parts 26 are slightly inclined backward.

[0036] 1, 2, 7 and 8, the pair of case support parts 26 are formed such that the length (height) in the up-down direction is shorter than the length (height) in the longitudinal direction of the device case 3 and is longer (higher) than the length of the battery lid 7 in the longitudinal direction of the device case 3. In addition, an opening 26a is provided between the pair of case support parts 26, extending from the bottom of the mounting recess 25a of the case mounting part 25 to each upper end.

[0037] In this case, as shown in Figures 2 and 7, the opening 26a between a pair of case support parts 26 is formed so that its length (spacing) in the short direction of the equipment case 3 is slightly longer than the width direction length of the hand belt 22 attached to the back surface of the equipment case 3, i.e., the length in the short direction perpendicular to the longitudinal direction of the hand belt 22.

[0038] As a result, the cradle 2 is configured so that when the other end 3b of the equipment case 3 is attached to the case attachment portion 25 and both short side portions of the equipment case 3 are supported by a pair of case support portions 26, as shown in Figures 2 and 7, the hand belt 22 attached to the back surface of the equipment case 3 is positioned within the opening 26a between the pair of case support portions 26.

[0039] As shown in Figures 2 and 7 to 9, the cradle 2 has a first holding portion 36 that holds the other end 3b side of the device case 3 of the mobile terminal 1, and a second holding portion 37 that holds the one end 3a side of the device case 3 closer to the battery cover 7 of the device case 3, and is configured to hold the device case 3 at two points, the first holding portion 36 and the second holding portion 37.

[0040] 2 and 7 to 9, the first retaining portion 36 is provided with a pair of pressing ribs 36a that press both sides in the short direction of the device case 3 on the other end 3b side of the device case 3 in the thickness direction, which is the front surface direction of the device case 3. The pair of pressing ribs 36a are provided on both sides of the inner surface on the front side in the mounting recess 25a of the case mounting portion 25 along the up-down direction.

[0041] As a result, as shown in Figures 2 and 7 to 9, when the other end 3b of the equipment case 3 is attached to the case mounting portion 25, both side portions on the front side of the other end 3b of the equipment case 3 are pressed against a pair of pressing ribs 36a and the back surface of the other end 3b of the equipment case 3 is pressed against the inner surface on the rear side of the mounting recess 25a, so that the pair of first retaining portions 36 are configured to hold the other end 3b of the equipment case 3 in the mounting recess 25a of the case mounting portion 25 with the equipment case 3 tilted slightly backward.

[0042] 2, 7 and 8, the second holding portion 37 includes a pair of locking pins 37a provided on the pair of case support portions 26 for releasably locking both sides in the short direction of the device case 3 at one end portion 3a side of the device case 3, and a pair of pin engagement grooves 38 provided on the device case 3 for releasably engaging with the pair of locking pins 37a. The pair of locking pins 37a are provided on the upper sides of the pair of case support portions 26 protruding toward the front side of the cradle 2, and are configured to releasably engage with the pair of pin engagement grooves 38 provided on the back surface of the device case 3.

[0043] 4 and 10, the pair of pin engagement grooves 38 are provided near the lock lever 12 that locks the battery lid 7 to the device case 3, that is, adjacent to the lever storage recess 9 of the lock lever 12 that locks one end 7c of the battery lid 7 on the one end 3a side of the device case 3. In other words, the pair of pin engagement grooves 38 are provided from both side portions in the short direction of the device case 3 to the pair of lever storage recesses 9.

[0044] 2, 4, 7 and 10, the pair of pin engagement grooves 38 are formed to a depth approximately equal to the protruding length of a pair of locking pins 37a provided protruding from a pair of case support parts 26 of the cradle 2 toward the front side of the cradle 2. In addition, the pair of pin engagement grooves 38 are provided so as to communicate with the pair of lever storage recesses 9, respectively.

[0045] As a result, as shown in Figures 2 and 7 to 9, when the other end 3b of the device case 3 of the mobile terminal 1 is inserted from above into the mounting recess 25a of the case mounting portion 25, the cradle 2 is configured so that the other end 3b of the device case 3 is held within the mounting recess 25a of the case mounting portion 25 by a pair of retaining ribs 36a of the first holding portion 36, and the pair of locking pins 37a engage with a pair of pin engagement grooves 38 provided on the back surface of the device case 3, thereby holding the mobile terminal 1 in a slightly tilted backwards state.

[0046] 7 and 8, the auxiliary charging section 27 of the cradle 2 is provided on the back surface of the case mounting section 25. That is, the length of the auxiliary charging section 27 in the short direction of the device case 3 is the same as that of the case mounting section 25, and the height of the auxiliary charging section 27 is higher than the front portion of the mounting recess 25a of the case mounting section 25. The auxiliary charging section 27 is provided with a battery mounting section 27a in which the battery pack 21 to be stored in the battery storage section 10 of the device case 3 or a spare battery pack 21 is disposed.

[0047] That is, as shown in Fig. 8, the battery mounting section 27a is configured so that the rectangular battery pack 21 is inserted from above in a vertically elongated state, and the battery pack 21 is arranged at an angle in a state substantially parallel to the mobile terminal 1 attached to the cradle. The depth of the battery mounting section 27a is formed to be shorter than the longitudinal length of the battery pack 21. Furthermore, the battery mounting section 27a is configured so that when the battery pack 21 is arranged, the battery pack 21 is electrically connected to the battery mounting section 27a to charge the battery pack 21.

[0048] 10 to 12, inside the device case 3, a card mounting section 13 is provided exposed inside the battery storage section 10. That is, a card 14 (not shown), such as a SIM card (a communication card) or a memory card, is detachably mounted in this card mounting section 13. This card mounting section 13 is provided inside the device case 3 at a position corresponding to the base of the second inclined surface 6b of the storage protrusion 6 of the device case 3, and is configured so that the card 14 can be inserted and removed inside the battery storage section 10.

[0049] 10 to 12, the card mounting section 13 is provided with a release lever 15 for removing the mounted card 14. The release lever 15 is provided in a narrow portion 16 in the device case 3, and an operation end portion 15a of the release lever 15 is configured to be exposed in the battery storage section 10. That is, the narrow portion 16 in the device case 3 is located between the card mounting section 13 and a battery connection portion 17 that are arranged next to the card mounting section 13 in the short side direction of the device case 3, and is a narrow portion whose height in the up-down direction is approximately the same as the thickness of the card 14 in the front-back direction.

[0050] For this reason, as shown in Fig. 3 and Fig. 10 to Fig. 12, it is difficult for the user to operate the release lever 15 with the fingertip of his / her hand, and it is designed to be operated using a touch pen 8. That is, as shown in Fig. 3 and Fig. 10, the touch pen 8 is detachably mounted on the device case 3 or a hand belt 22 attached to the back surface of the device case 3, and includes a pen body 8a, a pen tip 8b provided at one end of the pen body 8a for touching and operating the transparent touch panel of the input display unit 4, a clip portion 8d provided on the other end 8c side opposite to the pen tip 8b, and a lever operation portion 18 provided at the other end 8c.

[0051] 3 and 10 to 12, the lever operation unit 18 has a protrusion 18a that presses the release lever 15 provided in the narrow portion 16 inside the device case 3. The thickness of the protrusion 18a of the lever operation unit 18 in the direction perpendicular to the central axis of the pen body 8a (the vertical direction in FIG. 10) is formed to be thinner than the thickness of the pen tip 8b, that is, the diameter of the hemispherical portion that is the touch portion of the pen tip 8b.

[0052] 3 and 10 to 12, the lever operation part 18 has a first inclined surface 18b inclined in a direction from the pen tip 8b toward the other end 8c of the pen body 8a, and the first inclined surface 18b is provided with a protrusion 18a. The end surface of the clip part 8d on the lever operation part 18 side is also formed as an inclined surface with the same inclination as the first inclined surface 18b. In this case, the first inclined surface 18b and the inclined surface of the clip part 8d are intended to make it easier for the user to see the protrusion 18a when pressing the release lever 15 with the lever operation part 18.

[0053] 3 and 10 to 12, the protrusion 18a provided on the first inclined surface 18b has a second inclined surface 18d inclined in a direction from the pen tip 8b toward the other end 8c of the pen body 8a, and the second inclined surface 18d is inclined substantially parallel to the first inclined surface 18b of the lever operating part 18. As a result, the lever operating part 18 is configured so that the end surface 18c of the protrusion 18a and the release lever 15 are easily visible to the user when pressing the release lever 15.

[0054] 10 to 12, the protruding end face 18c of the protruding portion 18a is formed to have a height approximately equal to the thickness in the front and back directions of the card 14 to be attached to the card attachment portion 13 in the device case 3. As a result, the protruding portion 18a is configured so that the release lever 15 arranged in the narrow portion 16 in the device case 3 can be pressed.

[0055] Next, the operation of such a charging system will be described. First, a case will be described where card 14 such as a SIM card (communication card) or a memory card inserted in card insertion section 13 in mobile terminal 1 is replaced. In this case, battery cover 7 is removed and battery pack 21 is taken out from battery storage section 10. At this time, lever portions 12b of a pair of lock levers 12 are swung within lever storage recess 9 to rotate lock portion 12a, and one end 7c of battery cover 7 is unlocked by lock portion 12a.

[0056] When the lever portion 12b is operated to rotate the lock portion 12a in this manner, the lever portion 12b is operated smoothly because the pin engagement groove 38 of the device case 3 is provided in the vicinity of the lock lever 12 and communicates with the lever storage recess 9 which is the operation area of ​​the lock lever 12. In other words, when the lever portion 12b is swung, the operation area of ​​the lock lever 12 is widened by the pin engagement groove 38, so that when the lever portion 12b is operated with a fingertip, the pin engagement groove 38 improves the operability of the fingertip.

[0057] As a result, the battery cover 7 is removed from the battery housing section 10, and the battery pack 21 is taken out from inside the battery housing section 10. Then, part of the card mounting section 13 inside the device case 3, i.e., part of the card 14 mounted in the card mounting section 13, and the operation end section 15a which is part of the release lever 15 of the card mounting section 13 arranged in the narrow section 16 inside the device case 3, are exposed inside the battery housing section 10. In this state, the release lever 15 is pressed with the touch pen 8.

[0058] At this time, the other end 8c opposite to the pen tip 8b of the touch pen 8 is inserted into the battery storage section 10 of the device case 3, and as shown in Fig. 11, the protrusion 18a of the lever operation part 18 of the touch pen 8 is made to correspond to the operation end 15a of the release lever 15. In this case, the protrusion 18a is provided on a first inclined surface 18b of the lever operation part 18 provided at an incline on the other end 8c of the touch pen 8, and a second inclined surface 18d provided on an end surface 18c of this protrusion 18a is inclined substantially parallel to the first inclined surface 18b.

[0059] Therefore, when the protrusion 18a of the lever operation part 18 is made to correspond to the operation end 15a of the release lever 15, the first inclined surface 18b of the other end 8c of the touch pen 8 and the second inclined surface 18d of the protrusion 18a allow the user to clearly see the protrusion 18a and the operation end 15a of the release lever 15. This allows the protrusion 18a to be accurately made to correspond to the operation end 15a of the release lever 15 arranged in the narrow portion 16 inside the device case 3.

[0060] Then, the protrusion 18a of the lever operation portion 18 of the touch pen 8 is pressed against the operation end portion 15a of the release lever 15, and this protrusion 18a presses the operation end portion 15a of the release lever 15. Then, the card 14 mounted in the card mounting portion 13 can be removed from the card mounting portion 13 by the release lever 15 which has been pressed.

[0061] In this case, even if the release lever 15 is positioned in the narrow section 16 inside the device case, the thickness of the protrusion 18a of the lever operating section 18 of the touch pen 8 in a direction perpendicular to the central axis of the pen body 8a is thinner than the thickness of the pen tip 8b, i.e., the diameter of the hemispherical portion which is the touch portion of the pen tip 8b, and therefore the release lever 15 can be pressed and operated effectively by the protrusion 18a.

[0062] That is, the narrow portion 16 inside the device case is located between the card mounting portion 13 and the battery connection portion 17 arranged next to the card mounting portion 13 in the short side direction of the device case 3, and is a narrow portion whose height in the up-down direction is approximately the same as the thickness in the front-back direction of the card 14. In addition, the end face 18c in the protruding direction of the protrusion 18a of the lever operation portion 18 is formed with a height approximately the same as the thickness in the front-back direction of the card 14 mounted in the card mounting portion 13 inside the device case 3.

[0063] Therefore, protrusion 18a can reliably and satisfactorily press operation end 15a of release lever 15 disposed in narrow section 16 in device case 3. This allows card 14, such as a SIM card (communication card) or memory card, attached to card attachment section 13 in mobile terminal 1 to be easily removed and replaced.

[0064] Next, a case where the mobile terminal 1 is used after being removed from the cradle 2 will be described. In this case, the battery pack 21 is stored in advance in the battery storage section 10 in the device case 3, the battery storage section 10 is covered with the battery lid 7, and the battery lid 7 is locked with the pair of lock levers 12. In this state, the hand belt 22 is attached to the back surface of the device case 3.

[0065] At this time, one end 22a of the hand belt 22 is attached to the belt attachment fitting 24 of the belt attachment cover 23 attached to the second inclined surface 6b of the storage protrusion 6 of the device case 3, and the other end 22b of the hand belt 22 is attached to the belt attachment hole 3d provided in the other end 3b of the device case 3. As a result, the hand belt 22 is attached to the back surface of the mobile terminal 1 along its longitudinal direction.

[0066] When the user uses the mobile terminal 1 by holding it in his / her hand, he / she first inserts his / her hand between the device case 3 and the hand belt 22 to grasp the device case 3. At this time, the fingers of the hand except for the thumb are inserted between the device case 3 and the hand belt 22, the thumb is placed on the input display unit 4 or the key input unit 5 of the device case 3, and the user grasps the device case 3 by wrapping the battery cover 7 therearound.

[0067] In this state, the user performs input operation on the key input unit 5 with the thumb, and simultaneously touches the input display unit 4 with the touch pen 8. 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 that the user can touch the transparent touch panel 4b with the pen tip 8b of the touch pen 8 while viewing the information displayed on the display panel 4a.

[0068] In this state, when either the top trigger key of the multiple key buttons 5a in the key input unit 5 or the side trigger key 3c provided on the side of the device case 3 is operated, the scanner unit of the optical reading unit stored in the storage protrusion 6 of the device case 3 is driven. Then, the laser reading unit of the scanner unit irradiates a laser beam through the optical window 6c of the storage protrusion 6 onto the product code of the product and receives the reflected light to read the product code.

[0069] At this time, the camera unit of the scanner unit photographs the product or other object. As a result, the product code read by the laser reading unit is displayed on the input / display unit 4 and is registered in a memory unit (not shown) in the device case 3. Similarly, the product or other object photographed by the camera unit is displayed on the input / display unit 4 and is registered in the memory unit.

[0070] Next, a case where the portable terminal 1 is attached to the cradle 2 to transmit and receive data and to charge the portable terminal 1 will be described. At this time, the other end 3b of the device case 3 of the mobile terminal 1 is inserted from above into the mounting recess 25a of the case mounting part 25 of the cradle 2. Then, both sides of the connection electrode part 20 provided on the other end 3b of the device case 3 are pressed against and supported by a pair of spring members 35 located on both sides of the cradle connection part 28 provided on the case mounting part 25 and protruding from inside the case mounting part 25 into the mounting recess 25a.

[0071] At this time, the electrodes 20a of the connection electrode section 20 provided at the other end 3b of the device case 3 do not come into contact with the multiple connection pins 30 of the cradle connection section 28, and the other end 3b of the device case 3 is elastically supported by the pair of spring members 35. In this state, when the other end 3b of the device case 3 is pushed into the mounting recess 25a of the case mounting section 25 against the spring force of the pair of spring members 35, the electrodes 20a of the connection electrode section 20 of the device case 3 come into contact with the tips 30a of the multiple connection pins 30 of the cradle connection section 28, pushing down the multiple connection pins 30.

[0072] At this time, the multiple leaf springs 31 of the cradle connection portion 28 are each flexed downward and contact each board electrode of the connection board 33. This electrically connects the connection electrode portion 20 of the device case 3 and the cradle connection portion 28 of the cradle 2. Also, at this time, the other end portion 3b of the device case 3 is attached to the attachment recess 25a of the case attachment portion 25 of the cradle 2 and held by the first holding portion 36.

[0073] That is, when the other end 3b of the device case 3 is attached to the attachment recess 25a of the case attachment part 25, both sides on the front side of the other end 3b of the device case 3 are pressed against a pair of pressing ribs 36a of the first holding part 36, and the back surface of the other end 3b of the device case 3 is pressed against the inner surface on the rear side of the attachment recess 25a. As a result, the other end 3b of the device case 3 is held in the attachment recess 25a of the case attachment part 25 with the device case 3 slightly tilted backward.

[0074] At this time, one end 3a side of the device case 3 is held by the pair of case support parts 26 through the second holding parts 37 provided on the pair of case support parts 26. That is, when the other end 3b of the device case 3 is held in the mounting recess 25a of the case mounting part 25 by the first holding part 36, both side parts of the back surface of the device case 3 in the short direction of the device case 3 are pressed against the pair of case support parts 26 of the cradle 2.

[0075] Therefore, a pair of locking pins 37a of the second holding portion 37 provided on the upper side of the pair of case support portions 26 engage with a pair of pin engagement grooves 38 provided on the back surface of the device case 3. This allows the device case 3 to be held by the cradle 2 in a state in which it is slightly tilted backward. At this time, even if the hand belt 22 is attached to the back surface of the device case 3, the hand belt 22 is disposed within the opening 26a provided between the pair of case support portions 26, so that the device case 3 is favorably held by the cradle 2 in a state in which it is slightly tilted backward.

[0076] Therefore, when the device case 3 is held by the cradle 2 in a state where it is tilted slightly backwards, the connection electrode portion 20 of the device case 3 and the cradle connection portion 28 of the cradle 2 are electrically connected, so that data can be exchanged between the mobile terminal 1 and the cradle 2 and the battery pack 21 of the mobile terminal 1 is charged.

[0077] Thus, this charging system comprises a portable terminal 1 having a battery cover 7 provided on one of its back surfaces, a case attachment section 25 which is an insertion section into which the other end 3b of the portable terminal 1 is inserted, and a cradle 2 having a case support section 26 which protrudes upward from the case attachment section 25 and is arranged on the back side of the one end 3a of the portable terminal 1, the case attachment section 25 having a first holding section 36 which holds the other end 3b side of the portable terminal 1, and the case support section 26 has a second holding section 37 which holds the back side of the portable terminal 1 closer to the one end 3a than the battery cover 7, and the portable terminal 1 is held by the first holding section 36 and the second holding section 37, so that the portable terminal 1 can be stably held in the cradle 2.

[0078] That is, in this charging system, the other end 3b side of the portable terminal 1 can be held by the first holding part 36 of the cradle 2, and the one end 3a side of the portable terminal 1 can be held by the second holding part 37 of the cradle 2, which is closer to the battery cover 7 of the portable terminal 1. Therefore, the portable terminal 1 can be satisfactorily held by the cradle 2 at two points, the first holding part 36 and the second holding part 37, with a gap in the longitudinal direction of the battery cover 7, so that the portable terminal 1 can be stably held by the cradle 2.

[0079] In this case, in this charging system, a connection electrode unit 20 is provided at the other end 3b of the portable terminal 1, and the cradle 2 has a cradle connection unit 28 in its case attachment section 25 which is electrically connected to the connection electrode unit 20 of the portable terminal 1. Therefore, when the portable terminal 1 is held in the cradle 2, the connection electrode unit 20 provided at the other end 3b of the portable terminal 1 can be connected to the cradle connection unit 28 of the cradle 2, thereby enabling data to be exchanged between the portable terminal 1 and the cradle 2, and for the portable terminal 1 to be charged.

[0080] Furthermore, in this charging system, the battery cover 7 is provided from the other end 3b of the portable terminal 1 toward one end 3a, extending further toward the one end 3a than the middle part of the portable terminal 1, so that the battery cover 7 can be formed longer in the longitudinal direction of the portable terminal 1. This makes it possible to increase the longitudinal distance between the first holding portion 36 and the second holding portion 37, thereby enabling the portable terminal 1 to be held even more stably by the cradle 2.

[0081] In this case, in this charging system, the first holding portion 36 of the cradle 2 is provided with a pressing rib 36a that presses both sides of the short side perpendicular to the longitudinal direction of the mobile terminal 1 at the other end 3b side of the mobile terminal 1 in the front / back direction, i.e., the thickness direction, so that the pressing rib 36a can be pressed against both sides of the front side of the other end 3b of the device case 3, and the back side of the other end 3b of the device case 3 can be pressed against the inner surface on the rear side within the case mounting portion 25 of the cradle 2, thereby allowing the other end 3b of the mobile terminal 1 to be securely and favorably held within the case mounting portion 25 of the cradle 2.

[0082] Furthermore, in this charging system, the second holding portion 37 of the cradle 2 is provided with a locking pin 37a that detachably locks both sides of the short side of the portable terminal 1 on the one end 3a side of the portable terminal 1 relative to the battery cover 7, and a pin engagement groove 38 that detachably engages with the locking pin 37a, thereby enabling the one end 3a side of the portable terminal 1 to be securely and satisfactorily held on the case support portion 26 of the cradle 2.

[0083] In other words, in this charging system, when the other end 3b of the portable terminal 1 is attached to the case attachment portion 25 of the cradle 2, the locking pin 37a of the second holding portion 37 provided on the case support portion 26 of the cradle 2 can be engaged with the pin engagement groove 38 of the portable terminal 1, so that the one end 3a side of the portable terminal 1 can be securely and well held on the case support portion 26 of the cradle 2, thereby enabling the portable terminal 1 to be securely and well held in a stably mounted state on the cradle 2.

[0084] Also, in this charging system, the mobile terminal 1 is provided with a lock lever 12 that presses and locks the edge of the battery lid 7 at the one end 3a side, so that the battery lid 7 can be easily and reliably attached and locked to the mobile terminal 1 by the lock lever 12. That is, the other end 7d of the battery lid 7 is engaged with the edge of the battery housing section 10 at the other end 3b side of the mobile terminal 1, and one end 7c of the battery lid 7 is placed on the edge of the battery housing section 10 at the one end 3a side of the mobile terminal 1, and in this state, one end 7c of the battery lid 7 can be locked by the lock lever 12, so that the battery lid 7 can be easily and reliably locked to the mobile terminal 1.

[0085] In this case, in this charging system, the pin engagement groove 38 of the portable terminal 1 is provided near the lock lever 12 and is connected to the lever storage recess 9, which is the operation area of ​​the lock lever 12. Therefore, when the locking pin 37a of the second holding part 37 is engaged with the pin engagement groove 38 of the portable terminal 1 to hold the portable terminal 1 with the second holding part 37, the area of ​​the pin engagement groove 38 can be widened by the lever storage recess 9, thereby making it easier to engage the locking pin 37a of the second holding part 37 with the pin engagement groove 38 of the portable terminal 1.

[0086] In this case, in this charging system, the pin engagement groove 38 of the mobile terminal 1 is provided near the lock lever 12 and communicates with the lever storage recess 9 which is the operation area of ​​the lock lever 12, so that when the lever portion 12b of the lock lever 12 is swung, the operation area of ​​the lock lever 12 can be widened by the pin engagement groove 38. Therefore, when the lever portion 12b is operated with a fingertip, the pin engagement groove 38 can improve the operability of the fingertip.

[0087] Furthermore, in this charging system, the cradle 2 is provided with a spring member 35 that elastically supports the other end 3b of the portable terminal 1 before the connection electrode portion 20 of the portable terminal 1 is brought into contact with the cradle connection portion 28 of the cradle 2. Therefore, when the portable terminal 1 is held by the first holding portion 36, the connection electrode portion 20 of the portable terminal 1 can be brought into good contact with the cradle connection portion 28 of the cradle 2 with the other end 3b of the portable terminal 1 being elastically supported by the spring member 35.

[0088] Furthermore, in this charging system, an opening 26a, in which hand belt 22 attached to the back surface of mobile terminal 1 is placed, is provided in case support portion 26 of cradle 2 from case attachment portion 25 to the upper end portion of case support portion 26. Therefore, when mobile terminal 1 is attached to cradle 2, even if hand belt 22 is attached to the back surface of mobile terminal 1, hand belt 22 can be placed in opening 26a of cradle 2, thereby allowing mobile terminal 1 to be held well in cradle 2.

[0089] In the above embodiment, the touch pen 8 of the mobile terminal 1 has been described, but the present invention is not limited to this, and may be, for example, a tool. That is, the tool includes a first protrusion formed in a wedge shape for pressing a lever provided in a narrow portion inside the case, and a second protrusion formed with a predetermined curvature for performing an input operation by a touch operation.

[0090] In this case, the first protrusion may be provided at one end of a predetermined rod-shaped member, and the second protrusion may be provided at the other end opposite to the one end of the predetermined rod-shaped member. This type of jig also has the same effect as the touch pen 8.
