Subsequently, operations of the portable terminal configured as described above are described.
When assembling the portable terminal, the inner case 8 is formed in advance and the display unit 4, the input unit 5 and the circuit board 14 are mounted to the inner case 8. That is, when forming the inner case 8, the first frame 10 and the second frame 11 and the coupling part 12 are integrally formed by a synthetic resin such as an ABS resin, a composite material of PC resin and ABS resin, or the like.
At this time, the first buffer member 13 made of a synthetic resin having resiliency such silicon resin, elastomer or the like may be integrally embedded in the coupling part 12 by two-color molding. However, it is preferably to form the coupling part 12 with the slit-shaped fitting portion 12a and to fit the first buffer member 13 in the fitting portion 12a. In this case, the first buffer member 13 is fitted in the fitting portion 12a with pushing and enlarging the fitting portion 12a in the longitudinal direction of the inner case 8.
At this state, the display unit 4 is attached to the front surface of the first frame 10 and the circuit board 14 is attached to the back surface of the first frame 10. Also, the input unit 5 is attached to the front surface of the second frame 11. Then, the inner case 8 having the display unit 4, the circuit board 14 and the input unit 5 mounted thereto is incorporated into the upper case 2 of the device case 1.
In this case, the plurality of second buffer members 26 is respectively arranged at the respective outer peripheries of the small-diameter tip end portions of the plurality of support boss parts 25 provided in the upper case 2, in advance. At this time, the respective end faces of the front surface-side of the plurality of second buffer members 26 are elastically contacted to the step-shaped receiving portions 25a of the plurality of support boss parts 25 provided at the upper case 2 and the respective outer peripheral surfaces of the plurality of second buffer members 26 are elastically contacted to the inner peripheral surface of the upper case 2, i.e., the inner surface corresponding to the side surface perpendicular to the front surface of the upper case 2.
At this state, the inner case 8 is arranged in the upper case 2. At this time, the first to third mounting portions 30 to 32 of the inner case 8 are mounted to the respective outer peripheries of the plurality of second buffer members 26. That is, the first mounting portions 30 formed into the circular arc-shaped notch portion shape at both sides of the upper side of the first frame 10 are mounted to the second buffer members 26 corresponding to the first mounting portions, so that the first mounting portions 30 are elastically contacted and held to the outer peripheries of the second buffer members 26.
Likewise, the second mounting portions 31 formed into the projection shape at both sides of the lower side of the second frame 11 are bitten to the second buffer members 26 corresponding to the second mounting portions, so that the second mounting portions 31 are elastically held to the outer peripheries of the second buffer members 26. Also, the third mounting portions 32 formed into notched step portions at the portions positioned at both sides of the coupling part 12 and both sides of the battery accommodation part 15 are mounted to the second buffer members 26 corresponding to the third mounting portions, so that the third mounting portions 32 are elastically contacted and held to the outer peripheries of the second buffer member 26.
Thereby, the first to third mounting portions 30 to 32 are mounted to the respective outer peripheries of the plurality of second buffer members 26, so that the inner case 8 is kept in the upper case 2 by the plurality of second buffer members 26 without being in contact with the upper case 2. For this reason, the inner case 8 is kept in the upper case 2 at a state where the shock to be applied from the longitudinal direction of the inner case 8, the shock to be applied from the direction perpendicular to the longitudinal direction and the shock to be applied from the thickness direction, which is a front and back surface direction, are buffered by the plurality of second buffer members 26.
At this state, the display unit 4 is arranged in correspondence to the display opening 2a of the upper case 2, and the respective keys 5a of the input unit 5 are exposed outwards with being inserted into the key insertion holes 2b of the upper case 2. Also, at this time, the center trigger key 17a is exposed outwards with being inserted into the key insertion hole 2b of the upper case 2 and the side trigger keys 17b are exposed outwards with being inserted into the key insertion holes 2c of both sides of the upper case 2 positioned at both sides of the device case 1.
Then, the lower case 3 is attached to the upper case 2. At this time, the engaging protrusion 24 provided at the peripheral edge portion of the front surface-side of the lower case 3 is arranged to face the engaging groove 23 provided at the peripheral edge portion of the back surface-side of the upper case 2, the plurality of screw insertion portions 27 provided at the lower case 3 is arranged to face the plurality of support boss parts 25 provided at the upper case 2, and the upper case 2 and the lower case 3 are then superimposed at that state.
Thereby, the engaging protrusion 24 of the lower case 3 is fitted in the engaging groove 23 of the upper case 2, so that the upper case 2 and the lower case 3 are coupled to each other. At this state, the plurality of screws 28 is respectively inserted into the respective cylindrical portions 27a of the plurality of screw insertion portions 27 of the lower case 3, the respective screw portions 28b of the plurality of inserted screws 28 are inserted into the insertion holes of the respective contact portions 27b of the plurality of screw insertion portions 27 and the respective screw portions 28b of the plurality of inserted screws 28 are screwed and fastened to the plurality of support boss parts 25.
Thereby, the respective contact portions 27b of the plurality of screw insertion portions 27 of the lower case 3 are pressed and elastically contacted to the respective end faces of the back surface-side of the plurality of second buffer members 26 by the respective head portions 28a of the plurality of screws 28. In connection with this, the respective end faces of the front surface-side of the plurality of second buffer members 26 are pressed and elastically contacted to the respective step-shaped receiving portions 25a of the plurality of support boss parts 25 provided at the upper case 2. For this reason, the upper case 2 and the lower case 3 are fixed to each other via the plurality of second buffer members 26. As a result, the device case 1 is assembled.
At this state, the unit case 18 of the reading device 6 is attached to the back surface of the main body part 1a of the device case 1, i.e., the back surface of the lower case 3 corresponding to the main body part 1a of the device case 1 by the plurality of screws 18a. In this case, the reading unit 20 is arranged to face the reading window part 19a of the unit case 18 and the imaging unit 21 is arranged to face the imaging window part 19b of the unit case 18, and the reading unit 20 and the imaging unit 21 are mounted into the unit case 18 at that state, in advance.
Also, the battery 22 is accommodated in the battery accommodation part 15 provided at the second frame 11 of the inner case 8 corresponding to the gripping part 1b of the device case 1, and the battery accommodation part 15 provided in the gripping part 1b of the device case 1 is covered by the battery cover 7. At this state, the battery cover 7 is attached to the back surface of the lower case 3 corresponding to the gripping part 1b of the device case 1 by the screw 7a. Thereby, the portable terminal is assembled.
Subsequently, a using aspect of the portable terminal is described.
In this case, first, an operator grips the gripping part 1b of the device case 1 with a hand with the upper case 2 of the device case 1 facing upwards. At this state, since the display unit 4 and the input unit 5 of the upper case 2 face upwards, the operator can input information of goods, stocks thereof and the like by operating the diverse keys 5a of the input unit 5, and the input information is displayed on the display unit 4.
Also, when reading the code information and the image of the object to be read such as a label attached to the commercial goods by the reading device 6, the operator sets the reading window part 19a and the imaging window part 19b of the unit case 18 to face towards the object to be read and operates any one of the center trigger key 5b provided at the upper side part of the input unit 5 and the side trigger keys 5c provided at both sides of the device case 1. Thereby, the reading unit 20 of the reading device 6 reads the code information of the object to be read and the imaging unit 21 captures the object to be read, as an image, at the same time.
In this way, the code information and the image of the object to be read, which have been read by the reading device 6, are displayed on the display unit 4. For this reason, the operator operates the decision key 5a of the input unit 5 while seeing the code information and the image of the object to be read displayed on the display unit 4, so that the code information and the image of the object to be read displayed on the display unit 4 are stored.
In the meantime, when the device case 1 of the portable terminal is applied with the shock due to the dropping, for example, since the upper case 2 and the lower case 3 of the device case 1 are fixed to each other via the plurality of second buffer members 26, the shock applied to the device case 1 is buffered by the plurality of second buffer members 26.
That is, the plurality of second buffer members 26 is provided at the outer peripheries of the plurality of support boss parts 25 provided at the four corners in the upper case 2 and at both sides of the intermediate part of the upper case 2 in the longitudinal direction, the respective end faces of the front surface-side of the plurality of second buffer members 26 are in elastic contact with the respective step-shaped receiving portions 25a of the plurality of support boss parts 25 provided at the upper case 2, and the respective end faces of the back surface-side of the plurality of second buffer members 26 are in elastic contact with the respective contact portions 27b of the plurality of screw insertion portions 27 of the lower case 3. Therefore, when the device case 1 is applied with the shock in the thickness direction, it is possible to securely and favorably buffer the shock in the thickness direction by the plurality of second buffer members 26.
Also, the respective outer peripheries of the plurality of second buffer member 26 are in elastic contact with the inner peripheral surface of the upper case 2, i.e., the inner surface corresponding to the side surface perpendicular to the front surface of the upper case 2 at the state where the plurality of second buffer members 26 is provided at the outer peripheries of the plurality of support boss parts 25. Therefore, when the device case 1 is applied with the shock in the longitudinal direction or in the direction perpendicular to the longitudinal direction, it is possible to securely and favorably buffer the shock by the plurality of second buffer members 26. Thereby, it is possible to prevent the shock from being transmitted to the inner case 8 in the device case 1.
That is, since the plurality of second buffer members 26 is formed to have a substantially cylindrical shape conforming to the inner peripheral surface of the upper case 2, i.e., the inner surface corresponding to the side surface perpendicular to the front surface of the upper case 2 by the synthetic resin having high resiliency and hardness of about 80 to 90 such as silicon resin, elastomer or the like, it is possible to securely and favorably bring the outer peripheries thereof into elastic contact with the inner peripheral surface of the upper case 2.
In this case, the plurality of second buffer members 26 is formed with the protrusions 26a protruding in the direction following the inner peripheral surface of the upper case 2, i.e., the inner surface corresponding to the side surface perpendicular to the front surface of the upper case 2 so as to be in additionally elastic contact with the inner peripheral surface of the upper case 2. Thereby, when the device case 1 is applied with the shock from the outside, it is possible to further securely and favorably buffer the shock by the respective protrusions 26a of the plurality of second buffer members 26.
Also, the inner case 8 arranged in the device case 1 is kept in the device case 1 by the plurality of second buffer members 26 without being in contact with the device case 1. Therefore, even when the device case 1 is applied with the shock from the outside, the shock is buffered by the plurality of second buffer members 26, so that it is possible to prevent the shock applied to the device case 1 from being transmitted to the inner case 8. Thereby, it is possible to securely and favorably protect the components mounted on the inner case 8 such as the display unit 4, the input unit 5, the circuit board 14 and the like so that the components are not to be influenced by the shock.
That is, the inner case 8 has the first to third mounting portions 30 to 32 and the first to third mounting portions 30 to 32 are mounted to the respective outer peripheries of the plurality of second buffer members 26, so that it is possible to arrange the inner case 8 not to be in contact with the upper case 2 and the lower case 3 by the plurality of second buffer members 26. Thereby, even when the device case 1 is applied with the shock from the outside, it is possible to prevent the shock from being transmitted to the inner case 8.
In this case, the first mounting portions 30 formed into the circular arc-shaped notch portion shape at both sides of the upper side of the first frame 10 are mounted to the outer peripheries of the second buffer members 26 corresponding to the first mounting portions. The second mounting portions 31 formed into the projection shape at both sides of the lower side of the second frame 11 are bitten to the second buffer members 26 corresponding to the second mounting portions. The third mounting portions 32 formed into the notched step portions at the portions positioned at both sides of the coupling part 12 and the outer periphery of the battery accommodation part 15 are mounted to the outer peripheries of the second buffer members 26 corresponding to the third mounting portions. Therefore, it is possible to securely and favorably hold the inner case 8 in the device case 1 without being in contact with the device case 1.
That is, when the inner case 8 is held in the device case 1 with the first to third mounting portions 30 to 32 being mounted to the plurality of second buffer members 26, it is possible to securely and favorably buffer the shock to be applied from the longitudinal direction of the inner case 8, the shock to be applied from the direction perpendicular to the longitudinal direction and the shock to be applied from the thickness direction, which is a front and back surface direction of the inner case 8, by the plurality of second buffer members 26. For this reason, even when the device case 1 is applied with the shock from the outside, the shock is not transmitted to the inner case 8.
In the meantime, when the device case 1 is applied with the shock from the outside and the shock cannot be completely buffered by the plurality of second buffer members 26, the shock is transmitted to the inner case 8 in the device case 1. However, the shock transmitted to the inner case 8 is buffered by the first buffer member 13, so that it is possible to prevent the inner case 8 from being damaged due to the shock.
In this case, the first buffer member 13 is fitted to elastically push and enlarge the fitting portion 12a with being fitted in the slit-shaped fitting portion 12a of the coupling part 12 of the inner case 8 configured to couple the first frame 10 and the second frame 11. Thereby, it is possible to securely and favorably buffer the shock applied to the inner case 8 by the first buffer member 13.
That is, even when the device case 1 is applied with the shock from the outside and the shock is transmitted to the inner case 8 and is concentrated on the coupling part 12, the inner case 8 can securely and favorably buffer the shock concentrated on the coupling part 12 by the first buffer member 13. Therefore, it is possible to suppress the deterioration of the coupling part 12 due to the shock and to prevent the coupling part 12 from being damaged, thereby favorably protecting the coupling part 12.
In this case, since the heavy battery 22 is accommodated in the gripping part 1b of the device case 1, when the device case 1 is applied with the shock from the outside, the battery 22 generates the inertia force by the own weight and the shock resulting from the inertia force of the battery 22 is applied to the inner case 8. However, it is possible to securely and favorably buffer the shock due to the inertia force of the battery 22 by the first buffer member 13. For this reason, it is possible to suppress the deterioration of the coupling part 12 due to the shock of the inertia force of the battery 22, thereby preventing the coupling part 12 from being damaged.
Like this, the portable terminal includes the device case 1, which is an exterior member of which an inside is hollow, the plurality of support boss parts 25 provided in the inside of the device case 1 so as to stand up in the direction (i.e., the normal direction) perpendicular to the front and back surfaces of the device case 1, the plurality of second buffer members 26 provided around each of the plurality of support parts 25, and the inner case 8, which is an inner member kept in the inside of the device case 1 in parallel with the front and back surfaces of the device case 1 without being in contact with the device case 1 by the plurality of second buffer members 26. Thereby, it is possible to improve the shock resistance.
That is, according to the portable terminal, since the inner case 8 is kept in the inside of the device case 1 by the plurality of second buffer members 26 without being in contact with the device case 1, when the device case 1 is applied with the shock from the outside, it is possible to buffer the shock from the outside by the plurality of second buffer members 26 so that the shock is not transmitted to the inner case 8. Thereby, it is possible to improve the shock resistance. For this reason, according to the portable terminal, it is possible to favorably protect the components such as the display unit 4, the input unit 5, the circuit board 14 and the like mounted on the inner case 8 so that the components are not to be damaged due to the shock.
In this case, according to the portable terminal, the plurality of support boss parts 25 and the plurality of second buffer members 26 are provided at least at the four corners in the inside of the device case 1, so that it is possible to securely and favorably hold the four corners of the inner case 8 by the plurality of second buffer members 26. Thereby, it is possible to stably and favorably arrange the inner case 8 in the device case 1 and to securely and favorably buffer the shock from the outside by the plurality of second buffer members 26 provided at the four corners of the device case 1.
Also, according to the portable terminal, the plurality of support boss parts 25 and the plurality of second buffer members 26 are provided at both sides of the intermediate part in the longitudinal direction in the inside of the device case 1, too, so that it is possible to hold both sides of the intermediate part of the inner case 8 in the longitudinal direction by the plurality of support boss parts 25 and the plurality of second buffer members 26. For this reason, it is possible to further hold the inner case 8 in the device case 1 securely and favorably and to securely and favorably buffer the shock from the outside by the plurality of second buffer members 26 provided at both sides of the intermediate part in the longitudinal direction in the inside of the device case 1.
That is, according to the portable terminal, the inner case 8 has the first to third mounting portions 30 to 32 and the first to third mounting portions 30 to 32 are mounted to the respective outer peripheries of the plurality of second buffer members 26, so that it is possible to arrange the inner case 8 not to be in contact with the device case 1 by the plurality of second buffer members 26. Thereby, even when the device case 1 is applied with the shock from the outside, it is possible to prevent the shock from being transmitted to the inner case 8.
In this case, since the first mounting portions 30 formed into the circular arc-shaped notch portion shape at both sides of the upper side of the first frame 10 are mounted to the outer peripheries of the second buffer members 26 corresponding to the first mounting portions, the second mounting portions 31 formed into the projection shape at both sides of the lower side of the second frame 11 are bitten to the second buffer members 26 corresponding to the second mounting portions, and the third mounting portions 32 formed into the notched step portions at the portions positioned at both sides of the coupling part 12 and the outer periphery of the battery accommodation part 15 are mounted to the outer peripheries of the second buffer members 26 corresponding to the third mounting portions, it is possible to securely and favorably hold the inner case 8 not to be in contact with the device case 1.
That is, when the inner case 8 is held in the device case 1 with the first to third mounting portions 30 to 32 being mounted to the plurality of second buffer members 26, it is possible to securely and favorably buffer the shock to be applied from the longitudinal direction of the device case 1, the shock to be applied from the direction perpendicular to the longitudinal direction and the shock to be applied from the thickness direction, which is a front and back surface direction of the device case 1, by the plurality of second buffer members 26. For this reason, even when the device case 1 is applied with the shock from the outside, the shock is not transmitted to the inner case 8.
Also, according to the portable terminal, the respective outer peripheral surfaces of the plurality of second buffer members 26 are formed to have the shape conforming to the inner peripheral surface of the device case 1, i.e., the inner surface corresponding to the side surface perpendicular to the front and back surfaces of the device case 1 and are in elastic contact with the inner peripheral surface of the device case 1. Thereby, when the device case 1 is applied with the shock from the longitudinal direction of the device case 1 and the shock from the direction perpendicular to the longitudinal direction, it is possible to securely and favorably buffer the shocks by the plurality of second buffer members 26 and to prevent the shocks from being transmitted to the inner case 8.
In this case, the plurality of second buffer members 26 is formed with the protrusions 26a protruding in the direction following the inner peripheral surface of the upper case 2, i.e., the inner surface corresponding to the side surface perpendicular to the front surface of the upper case 2 so as to be in additionally elastic contact with the inner peripheral surface of the device case 1. Thereby, when the device case 1 is applied with the shock from the outside, it is possible to buffer the shock by the respective protrusions 26a of the plurality of second buffer members 26, too. Therefore, it is possible to further buffer the shock applied to the device case 1 from the outside securely and favorably by the plurality of second buffer members 26 and to prevent the shock from being transmitted to the inner case 8.
Also, according to the portable terminal, the device case 1 has the upper case 2 and the lower case 3 and the plurality of support boss parts 25 is provided at least at the four corners in the inside of the upper case 2, so that it is possible to fix the four corners of the upper case 2 and the lower case 3 by the plurality of support boss parts 25 and the plurality of second buffer members 26. Thereby, it is possible to securely and favorably fix the upper case 2 and the lower case 3 and to securely and favorably buffer the shock from the outside by the second buffer members 26.
Also in this case, the device case 1 is provided with the support boss parts 25 and the second buffer members 26 at both sides of the intermediate part in the longitudinal direction in the inside of the device case 1, too, so that it is possible to fix both sides of the intermediate parts of the upper case 2 and the lower case 3 in the longitudinal direction by the plurality of support boss parts 25 and the plurality of second buffer members 26. For this reason, it is possible to further fix the upper case 2 and the lower case 3 securely and favorably and to securely and favorably buffer the shock from the outside by the plurality of second buffer members 26.
Also, in the device case 1, the plurality of screws 28, which are the fastening members, is fastened to the plurality of support boss parts 25 provided at the upper case 2 through the lower case 3. Therefore, since it is possible to screw and tighten the screws 28 to the support boss parts 25 of the upper case 2 through the lower case 3 from the outside of the lower case 3 with the upper case 2 and the lower case 3 being overlapped with each other, it is possible to simply and rigidly fix the upper case 2 and the lower case 3 each other.
In this case, the support boss part 25 is formed to have a cylindrical shape, the step-shaped protruding receiving portion 25a is formed at the outer periphery thereof, the lower case 3 is provided with the screw insertion hole portion 27 in which the screw 28 is to be inserted from the outside, and the second buffer member 26 is arranged between the receiving portion 25a of the support boss part 25 and the end portion of the screw insertion hole portion 27 of the lower case 3. Thereby, when the upper case 2 and the lower case 3 are tightened and fixed by the screws 28, it is possible to elastically sandwich the second buffer members 26 between the receiving portions 25a of the support boss parts 25 and the end portions of the screw insertion hole portions 27 of the lower case 3.
That is, in the device case 1, at the state where the upper case 2 and the lower case 3 are overlapped with each other, the screw 28 is inserted into the screw insertion hole portion 27 of the lower case 3 from the outside of the lower case 3, the screw portion 28b of the inserted screw 28 is inserted into the insertion hole of the contact portion 27b provided at the end portion of the screw insertion hole portion 27 and the screw portion 28b of the inserted screw 28 is screwed and tightened to the support boss part 25 of the upper case 2.
For this reason, in the device case 1, the head portion 28a of the screw 28 can press the contact portion 27b of the screw insertion hole portion 27 to the second buffer member 26 and press the second buffer member 26 to the receiving portion 25a of the support boss part 25. Therefore, it is possible to securely and favorably sandwich the second buffer member 26 between the receiving portion 25a of the support boss part 25 and the contact portion 27b of the screw insertion hole portion 27 of the lower case 3.
Thereby, in the device case 1, the second buffer member 26 is elastically sandwiched between the receiving portion 25a of the support boss part 25 and the contact portion 27b of the screw insertion hole portion 27 of the lower case 3, so that when the device case 1 is applied with the shock from the thickness direction, which is a front and back surface direction of the device case, it is possible to securely and favorably buffer the shock by the second buffer member 26.
Meanwhile, in the above embodiment, the support boss parts 25 and the second buffer members 26 are provided in the upper case 2. However, the present invention is not limited thereto. For example, the support boss parts 25 and the second buffer members 26 may be provided in the lower case 3 and the screw insertion hole portions 27 may be provided in the upper case 2.
Also, in the above embodiment, the device case 1 is used as the exterior member. However, the present invention is not limited thereto. For example, a member of which an inside is hollow, such as a housing may also be used.
Also, in the above embodiment, the inner case 8 is used as the inner member. However, the present invention is not limited thereto. For example, a member such as a frame member and a flat plate member may also be used.
Also, in the above embodiment, the present invention is applied to the portable terminal. However, it is not necessarily required to apply the present invention to the portable terminal. For example, the present invention can be applied to a portable device such as a mobile phone, a portable information processing device and the like.
