[0014] As shown in Fig. 1, the input display unit 4 is provided on the top surface of the upper case 2, occupying a wide area of ​​approximately four-fifths of the device case 1 in the longitudinal direction from one end 1a to the other end 1b. The input display unit 4 is a display panel with a transparent touch panel laminated on the top surface of the display panel. The display panel is a flat display element such as a liquid crystal display element or an EL (electroluminescence) display element, and displays information electro-optically. The transparent touch panel accepts information input when a user touches the transparent touch panel while looking at information displayed on the display panel.

[0015] The key input unit 5 receives key operation inputs from the user and outputs the operation information to a control unit (not shown) of the mobile terminal 100. As shown in FIG. 1, the key input unit 5 includes function keys 5a arranged in an area on the other end 1b side of the device case 1 on the top surface of the upper case 2. The function keys 5a receive various inputs from the user. The function keys 5a are provided in an area on the top surface of the upper case 2 excluding the input display unit 4, that is, in a narrow area of ​​about one-fifth of the area on the top surface of the upper case 2 from the other end 1b in the longitudinal direction of the device case 1 to the input display unit 4. As shown in FIG. 3, the key input unit 5 includes a power button 5b on the right side surface of the device case 1. The power button 5b receives a power on / off input from the user. As shown in FIGS. 1 to 3, the key input unit 5 includes trigger keys 5c on the right and left sides of the device case 1. The trigger keys 5c receive, for example, a scan execution input from the user to the scanner unit 6.

[0016] As shown in Fig. 4, the scanner unit 6 is provided on the top surface of the device case 1, which is the end surface of the lower case 3 located on one end 1a side of the device case 1. The scanner unit 6 reads a code symbol (e.g., a barcode) that is a subject, decodes the obtained signal, and outputs the signal to the control unit. At least a part of the decoding process of the code symbol reading result may be executed by the control unit. For example, the user points the scanner unit 6 of the mobile terminal 100 so as to face the code symbol, and the user presses the trigger key 5c to read the code symbol.

[0017] As shown in Fig. 2A and Fig. 2B, the camera unit 71 and the LED 72 are provided on the back surface of the device case 1, i.e., the bottom surface of the lower case 3. The camera unit 71 has an optical system and an imaging element, and captures an image of a subject to generate image data. The camera unit 71 captures an image of, for example, a two-dimensional code. The LED 72 is provided in the vicinity of the camera unit 71, and irradiates light onto the subject of the camera unit 71.

[0018] As shown in FIG. 2A, the battery lid 8 is provided on the lower surface of the lower case 3 and closes the battery housing section 10 (see FIG. 2B) in the lower case 3 in an openable and closable manner. As shown in FIG. 3 and FIG. 5, the battery lid 8 has a shape that protrudes downward in accordance with the shape of the battery pack 200 housed in the battery housing section 10. As shown in FIG. 2A, when the battery lid 8 is placed in the lower case 3 to close the battery housing section 10, the other end 8b of the battery lid 8 on the other end 1b side of the device case 1 is engaged with the edge of the battery housing section 10, and one end 8a of the battery lid 8 on the one end 1a side of the device case 1 is placed on the edge of the battery housing section 10. In this case, when the battery lid 8 is placed in the lower case 3 to close the battery housing section 10, the one end 8a is locked by the lock lever 9.

[0019] As shown in Fig. 2A, the lock levers 9 are provided on the lower case 3 at positions located near both sides of one end 8a of the battery lid 8. The lock levers 9 include a substantially circular lock portion 9a and a lever portion 9b. The lock portion 9a is rotatably provided on the lower case 3 and detachably locks the one end 8a of the battery lid 8. The lever portion 9b extends from the lock portion 9a toward the one end 1a of the device case 1 and rotates the lock portion 9a.

[0020] 2A and 2B, the lock lever 9 is disposed in a substantially sector-shaped lever storage portion 3a provided in each lower case 3. That is, the lock lever 9 is configured such that the lock portion 9a is rotatably provided at a required position in the sector-shaped lever storage portion 3a, and the lever portion 9b swings within the sector-shaped lever storage portion 3a.

[0021] As a result, when the lock lever 9 is placed in the lower case 3 with the battery lid 8 covering the battery storage section 10 of the lower case 3, as shown in Figure 2A, and the lever portion 9b is swung within the lever storage section 3a to rotate the lock portion 9a in one direction, the lock portion 9a presses one end 8a of the battery lid 8 against the edge of the battery storage section 10 to lock it.

[0022] In addition, as shown in Figures 2A and 2B, when the lock portion 9a locks one end 8a of the battery lid 8, the locking of one end 8a of the battery lid 8 by the lock portion 9a is released by swinging the lever portion 9b in the opposite direction to rotate the lock portion 9a in the opposite direction.

[0023] As shown in Fig. 2B, the battery accommodating section 10 is provided on the lower surface of the lower case 3 and accommodates the battery pack 200. As shown in Fig. 8 and Fig. 11, the battery accommodating section 10 includes a cover section 10c, an inserted section 10d, a side restriction member 10e, a second connection terminal 10f, etc. The cover section 10c, the inserted section 10d, the side restriction member 10e, and the second connection terminal 10f will be described in detail later.

[0024] 2B , when the battery pack 200 is accommodated in the battery accommodating section 10, one end 200a of the battery pack 200 is located at one end 10a of the battery accommodating section 10, and the other end 200b of the battery pack 200 is located at the other end 10b of the battery accommodating section 10. The battery accommodating section 10 is formed to be approximately the same size as the battery pack 200.

[0025] 5, the connection electrode section 11 is provided on the bottom surface, which is the end surface of the lower case 3 located on the other end 1b side of the device case 1. The connection electrode section 11 has a plurality of arranged electrodes 11a, and is electrically connected to an external device (not shown) such as a cradle to transmit and receive information and charge the battery pack 200 in the battery housing section 10.

[0026] [2. Configuration of the battery pack and battery housing] FIG. 6A shows a front view of the battery pack 200. FIG. 6B shows a rear view of the battery pack 200. FIG. 7 shows a partial perspective view of one end 200a of the battery pack 200. FIG. 8 shows a state in which the battery pack 200 is housed in the battery housing section 10. FIG. 9 shows a schematic cross-sectional view taken along line IX-IX in FIG. 2B. FIG. 10 shows a schematic cross-sectional view taken along line XX in FIG. 2B. FIG. 11 shows a partial perspective view of one end 10a of the battery housing section 10.

[0027] As shown in FIGS. 6A to 7, the battery pack 200 includes a main body portion 201, a protruding portion 202, and an insertion portion 203.

[0028] The protrusion 202 protrudes forward from one end 200a of the main body 201. As shown in Figs. 2B, 8, and 9, a front portion of the protrusion 202 is close to and covered by the cover 10c of the battery accommodating section 10 when the battery pack 200 is accommodated in the battery accommodating section 10. As shown in Figs. 8 and 11, the cover 10c is provided on the one end 10a side of the battery accommodating section 10. By covering the protrusion 202 with the cover 10c, the vertical movement of the battery pack 200 can be suppressed when the battery pack 200 is accommodated in the battery accommodating section 10. In other words, if the movement of the battery pack 200 is not suppressed in the battery accommodating section 10, the battery pack may move in the battery accommodating section when an impact such as a drop is applied, and the power supply terminal on the mobile terminal side and the power supply terminal on the battery pack side may momentarily become out of contact with each other. In this case, an instantaneous power interruption occurs, but in this embodiment, the protrusion 202 is covered by the cover portion 10c, thereby suppressing the vertical movement of the battery pack 200, thereby making it possible to further suppress the occurrence of such a power interruption.

[0029] As shown in Fig. 6A, the protruding portion 202 has a first connection terminal 202a on the upper surface. Note that the first connection terminal 202a is omitted in Fig. 9. That is, the first connection terminal 202a is provided to protrude from one end 200a side of the battery pack 200. Furthermore, when the battery pack 200 is accommodated in the battery accommodating portion 10 of the mobile terminal 100, the first connection terminal 202a is covered by a cover portion 10c of the battery accommodating portion 10.

[0030] 2B and 8, in a state in which the battery pack 200 is accommodated in the battery accommodating section 10, the second connection terminal 10f (see FIG. 11) of the battery accommodating section 10 is electrically connected to the first connection terminal 202a. As shown in FIG. 11, the second connection terminal 10f is provided on one end 10a side of the battery accommodating section 10.

[0031] As shown in Figs. 6A to 7, the protruding portion 202 has a curved surface 202b that is curved in a plan view at a corner with the one end 200a of the main body portion 201. As shown in Fig. 8, the curved surface 202b is close to the side restriction member 10e of the battery accommodating portion 10 when the battery pack 200 is accommodated in the battery accommodating portion 10. As shown in Fig. 11, the side restriction member 10e has a shape that protrudes rearward from the cover portion 10c along the bottom surface of the battery accommodating portion 10. That is, the battery accommodating portion 10 has the side restriction member 10e that is disposed to the side of the first connection terminal 202a when the battery pack 200 is accommodated in the battery accommodating portion 10 of the mobile terminal 100. The curved shape of the curved surface 202b is approximately the same as the curved shape of the curved surface 101e (see Fig. 11) of the side restriction member 10e. The lateral restriction members 10e can suppress movement of the battery pack 200 in the left-right and front-rear directions when the battery pack 200 is accommodated in the battery accommodating section 10. In this manner, in this embodiment, movement of the battery pack 200 in the front-rear direction is suppressed, so that the occurrence of the above-mentioned power interruption can be further suppressed.

[0032] 6B, 7, and 8, the protrusion 202 has a protruding portion 202c extending downward on the lower surface thereof. That is, the protruding portion 202c protrudes from the surface of the protrusion 202 opposite to the surface on which the first connection terminal 202a is formed.

[0033] As shown in Fig. 2B and Fig. 8, a front portion of the protrusion 202c is inserted into a notch 101c formed in the cover portion 10c when the battery pack 200 is accommodated in the battery accommodating portion 10. The notch 101c is formed on the rear side of the cover portion 10c as shown in Fig. 8. In other words, the battery accommodating portion 10 has a notch 101c corresponding to the protrusion 202c.

[0034] In a configuration in which cover portion 10c does not have notch 101c, protrusion 202c and cover portion 10c collide with each other, making it impossible to accommodate battery pack 200 in battery accommodating portion 10. Therefore, protrusion 202c can prevent the user from accidentally attaching battery pack 200 to a model of portable terminal other than portable terminal 100 that does not have notch 101c.

[0035] 6B and 7, the protruding portion 202 has an information display area 202d provided adjacent to the protruding portion 202c on the lower surface. The information display area 202d displays the polarity of the battery pack 200 when it is accommodated in the battery accommodating portion 10. The cover portion 10c of the battery accommodating portion 10 is provided so as to cover only a part of the information display area 202d so that the user can always identify the display content of the information display area 202d when performing an operation to accommodate the battery pack 200 in the battery accommodating portion 10.

[0036] 6A to 7, the battery pack 200 has insertion portions 203 at both left and right corners at one end 200a side. That is, the insertion portions 203 are formed at positions on the one end 200a side of the battery pack 200 different from the positions at which the first connection terminal 202a is provided.

[0037] Moreover, battery pack 200 is formed so that the thickness (vertical height) of protruding portion 202 is thinner than the thickness (vertical height) of main body portion 201. Moreover, battery pack 200 is formed so that the height (vertical height) of insertion portion 203 is thinner than the height (vertical height) of protruding portion 202.

[0038] As shown in Fig. 7, the insertion portion 203 protrudes diagonally from a corner 201a of the main body portion 201. As shown in Fig. 10, the insertion portion 203 is a flat plate-shaped member extending from the upper surface (top surface) of the main body portion 201. The radius of curvature of the corner 203a of the insertion portion 203 is smaller than the radius of curvature of the corner 201a of the main body portion 201, as shown in Fig. 7.

[0039] As shown in Fig. 2B, Fig. 8 and Fig. 10, the insertion portion 203 is inserted into the insertion receiving portion 10d of the battery accommodating portion 10 in a state where the battery pack 200 is accommodated in the battery accommodating portion 10. As shown in Fig. 8, the insertion receiving portion 10d is provided at the left and right corners on one end 10a side of the battery accommodating portion 10. By inserting the tip portion of the insertion portion 203 into the insertion receiving portion 10d, it is possible to suppress the vertical movement of the battery pack 200 in a state where the battery pack 200 is accommodated in the battery accommodating portion 10. As described above, the insertion portion 203 is formed thinner in the vertical direction than the protruding portion 202, and therefore it is possible to suppress the vertical movement of the battery pack 200 while preventing the vertical height of the battery accommodating portion 10 from increasing.

[0040] 10, the inserted portion 10d has an inclined surface 101d that slopes downward at a predetermined angle from the insertion opening side into which the insertion portion 203 is inserted toward the front side at a location facing the insertion portion 203 when the insertion portion 203 is inserted. This forms a space between the inserted portion 10d and the insertion portion 203, making it easier to attach and detach the battery pack 200 to and from the battery housing portion 10.

[0041] As described above, the protruding portion 202 and the cover portion 10c can suppress the vertical movement of the battery pack 200 at the left-right center of the battery pack 200. The inserted portion 10d and the insertion portion 203 can suppress the vertical movement of the battery pack 200 at both left-right ends of the battery pack 200. Therefore, when the battery pack 200 is accommodated in the battery accommodating portion 10, the vertical movement of the battery pack 200 can be suppressed with high reliability. The cover portion 10c and the inserted portion 10d function as a movement restricting portion.

[0042] [3. Operation when inserting and removing the battery pack] Next, the operation of inserting the battery pack 200 into the mobile terminal 100 will be described.

[0043] First, the battery lid 8 is removed from the device case 1, and the battery pack 200 is housed in the battery housing section 10. In this case, the lever portion 9b of the lock lever 9 is swung in the lever housing section 3a to rotate the lock portion 9a, thereby unlocking one end portion 8a of the battery lid 8 by the lock portion 9a.

[0044] In this state, the user places his or her fingers on the notches 3b (see FIGS. 2A and 2B) provided on both sides of the device case 1 corresponding to one end 8a of the battery lid 8, and lifts one end 8a of the battery lid 8 from the battery housing section 10. Then, the battery lid 8 rotates upward with the other end 8b as a fulcrum, and is removed from the battery housing section 10, opening the battery housing section 10.

[0045] In this state, the battery pack 200 is accommodated in the battery accommodating section 10. At this time, the battery pack 200 is inserted into the battery accommodating section 10 while being tilted so that the first connection terminal 202a provided on the protruding portion 202 of the battery pack 200 faces the second connection terminal 10f provided on one end portion 10a side of the battery accommodating section 10.

[0046] After the protruding portion 202 is inserted into the battery accommodating portion 10, the battery pack 200 is rotated so that the inclination of the battery pack 200 gradually decreases, and the battery pack 200 is brought into contact with the bottom of the battery accommodating portion 10. Then, the battery pack 200 is slid toward the second connecting terminal 10f. As a result, the first connecting terminal 202a approaches and is connected to the second connecting terminal 10f. Also, the inserting portion 203 is inserted into the receiving portion 10d. That is, the front portion of the protruding portion 202 is covered by the cover portion 10c, and the inserting portion 203 is covered by the receiving portion 10d, suppressing the movement of the battery pack 200 in the vertical direction. As a result, the battery pack 200 is accommodated in the battery accommodating portion 10.

[0047] Then, the battery housing section 10 is closed with the battery lid 8. At this time, the other end 8b of the battery lid 8 is engaged with the edge of the battery housing section 10 on the other end 10b side, and the battery lid 8 is rotated around the other end 8b of the engaged battery lid 8 as a fulcrum. Then, one end 8a of the battery lid 8 is engaged with the edge of the battery housing section 10 on the one end 10a side.

[0048] In this state, one end 8a of the battery lid 8 is locked by the lock lever 9. That is, the lever portion 9b of the lock lever 9 is swung inside the lever storage portion 3a to rotate the lock portion 9a, and the one end 8a of the battery lid 8 is locked by this rotated lock portion 9a.

[0049] Next, a case where the battery cover 8 is removed from the battery housing portion 10 and the battery pack 200 is replaced will be described.

[0050] First, the battery cover 8 is removed from the device case 1 as described above. When the battery cover 8 is removed from the battery housing section 10, the battery pack 200 in the battery housing section 10 is exposed. When removing the battery pack 200 from the battery housing section 10, the other end 200b of the battery pack 200 is pulled up from the battery housing section 10. Then, the battery pack 200 gradually tilts while rotating obliquely upward around the protrusion 202 provided on the one end 200a side of the battery pack 200, and slides toward the other end 1b of the device case 1. This allows the battery pack 200 to be removed from the battery housing section 10. In this state, the battery pack 13 can be replaced.

[0051] As described above, the operation of attaching and detaching battery pack 200 to and from mobile terminal 100 in the present invention is the same as the operation of attaching and detaching a battery pack to and from a conventional mobile terminal. In other words, the presence of insertion portion 203 in battery pack 200 does not affect the operation of attaching and detaching battery pack 200. In other words, insertion portion 203 has a shape that does not interfere with the operation of attaching and detaching battery pack 200.

[0052] [4. Effects] As described above, the battery pack 200 of this embodiment includes the first connection terminal 202a provided to protrude from one end (one end 200a) and the insertion portion 203 formed at a location on the one end different from the location where the first connection terminal 202a is provided. When the battery pack 200 is accommodated in the battery accommodating portion 10 of the mobile terminal 100, the first connection terminal 202a is covered by the cover portion 10c of the battery accommodating portion 10, and the insertion portion 203 is inserted into the insertion portion 10d of the battery accommodating portion 10, so that the relative movement of the battery pack 200 with respect to the mobile terminal 100 is suppressed. Therefore, the protrusion portion 202 provided with the first connection terminal 202a and the cover portion 10c can suppress the vertical movement of the battery pack 200. In addition, the insertion portion 10d and the insertion portion 203 can suppress the vertical movement of the battery pack 200. This can further reduce the effects of shock when the mobile terminal is dropped.

[0053] In the battery pack 200 of this embodiment, the insertion portion 203 is a flat plate-like member, and the inserted portion 10d has an inclined surface 101d that slopes downward from the insertion opening side into which the insertion portion 203 is inserted toward the back side at a location facing the insertion portion 203. This forms a space between the inserted portion 10d and the insertion portion 203, making it easier to attach and detach the battery pack 200 to and from the battery housing portion 10.

[0054] In the battery pack 200 of this embodiment, the insertion portions 203 are formed at both corners on one end (one end 200a) side. This makes it possible to suppress up-down movement of the battery pack 200 at both left-right ends of the battery pack 200.

[0055] In the battery pack 200 of this embodiment, the insertion portion 203 is formed to extend from the upper surface of the battery pack 200. As a result, one end side of the battery pack 200 is held by the first connection terminal 202a and the insertion portion 203, so that it is possible to suppress the load applied to the first connection terminal 202a when an impact such as a drop is applied, compared to a case where the insertion portion 203 is not provided.

[0056] In addition, there has been a problem in the past that a battery pack intended to be attached to the device case 1 of a specific mobile terminal may be attached to the device case of another mobile terminal. In response to this, in the present embodiment, the cutout 101c is formed on the cover part 10c side of the device case 1, and the protrusion 202c is formed on the battery pack 200 side, thereby making it possible to prevent the battery pack 200 from being attached to a mobile terminal other than the device case 1 of the specific mobile terminal. In addition, by providing the protrusion 202c on the side opposite to the side on which the first connection terminal 202a is provided, i.e., on the side opposite to the first connection terminal 202a side that is visually recognized by the user when the battery pack 200 is attached, the presence of the protrusion 202c is easily recognized when the battery pack 200 is attached, so that it is possible to more effectively prevent the battery pack 200 from being attached to another mobile terminal.

[0057] That is, the battery pack 200 of this embodiment has a protrusion 202c protruding from the surface opposite to the surface on which the first connection terminal 202a is formed, and the protrusion 202c is inserted into the notch 101c of the battery accommodating section 10 when the battery pack 200 is accommodated in the battery accommodating section 10. This makes it possible to prevent the user from mistakenly attaching the battery pack 200 to a model of mobile terminal other than the mobile terminal 100 that does not have the notch 101c.

[0058] In the battery pack 200 of this embodiment, the protrusion 202c is provided adjacent to the information display area 202d formed on the surface opposite to the surface on which the first connection terminal 202a is formed. This makes it possible to display the polarity of the battery pack 200 when it is accommodated in the battery accommodating section 10, even with the protrusion 202c.

[0059] The mobile terminal 100 of the present embodiment includes a battery pack 200 including a first connection terminal 202a provided to protrude from one end (one end 200a) and an insertion portion 203 formed at a position on the one end different from the position where the first connection terminal 202a is provided, and a battery housing portion 10 in which the battery pack 200 is accommodated. The battery housing portion 10 includes a movement restricting portion having a cover portion 10c that covers the first connection terminal 202a and an inserted portion 10d into which the inserting portion 203 is inserted, and the movement restricting portion restricts the relative movement of the battery pack 200 accommodated in the battery housing portion 10 with respect to the battery housing portion 10. Therefore, the protruding portion 202 provided with the first connection terminal 202a and the cover portion 10c can restrict the vertical movement of the battery pack 200. In addition, the inserted portion 10d and the inserting portion 203 can restrict the vertical movement of the battery pack 200. This can further reduce the effects of shock when the mobile terminal is dropped.

[0060] Furthermore, in the mobile terminal 100 of this embodiment, the battery accommodating section 10 includes a side restriction member 10e disposed on the side of the first connection terminal 202a when the battery pack 200 is accommodated in the battery accommodating section 10, and the side restriction member 10e restricts lateral movement of the battery pack 200 accommodated in the battery accommodating section 10. This makes it possible to restrict movement of the battery pack 200 in the left-right and front-back directions when the battery pack 200 is accommodated in the battery accommodating section 10, thereby making it possible to reliably restrict movement of the battery pack 200 in the left-right and front-back directions.

[0061] In the mobile terminal 100 of this embodiment, the curved shape of the curved surface 202b at the side of the first connection terminal 202a and the curved shape of the curved surface 101e of the side restriction member 10e are substantially the same. This makes it possible to further suppress the movement of the battery pack 200 in the left-right and front-rear directions when the battery pack 200 is accommodated in the battery accommodating section 10.

[0062] In the above embodiment, the inserted portion 10d has the inclined surface 101d that slopes downward at a predetermined angle from the insertion opening side into which the insertion portion 203 is inserted toward the back side at a location facing the insertion portion 203 when the insertion portion 203 is inserted, but this is not limited thereto. The surface of the insertion portion 203 that faces the inclined surface 101d may be substantially parallel to the inclined surface 101d.

[0063] Furthermore, the shape of the insertion portion 203 is not limited to the example shown in the above embodiment. The shape of the insertion portion 203 may be, for example, a shape that protrudes only forward from the corner portion 201a of the main body portion 201.

[0064] Although several embodiments of the present invention have been described, the scope of the present invention is not limited to the above-described embodiments, but includes the scope of the invention described in the claims and its equivalents. [Explanation of symbols]
