JP 2003-110253 A

  By the way, in order to meet the demand for higher efficiency of assembly, maintenance inspection, and repair of POS terminal devices, further improvement in detachability of the built-in devices from the housing is desired. In particular, in the case of maintenance inspection and field repair of a POS terminal device, an engineer who performs the work often goes to a store or the like. The work at the site is limited in time that can be spent and must be performed in a limited place, such as on a store counter, using limited tools that can be carried. In view of such circumstances, further improvement in workability of attaching / detaching each built-in device from the housing is strongly desired.

  Patent Document 1 discloses fixing the housing without a tool, but does not mention anything about the housing containing the device.

  On the other hand, a POS terminal device is often installed at a place where a store clerk and a customer conduct a face-to-face transaction, such as a cash register or counter of a store, a government office, or a service organization. On the cash register stand and counter, it is necessary to secure a space for delivering goods and money between the store clerk and the customer. On the other hand, peripheral devices such as bar code readers, IC card readers, RFID readers in addition to POS terminal devices A space to install is also necessary. For this reason, further miniaturization is desired for the POS terminal device.

  However, in order to reduce the size of the POS terminal, each built-in device is accommodated in an intricate state overlapping each other in a limited space in the housing. When the built-in devices are arranged at a high density in the housing in this manner, it may be difficult to apply an electric, air-driven or manual driver tool to the screwing location. In addition, before attaching or detaching the built-in device located in the back as viewed from the operator, it may be necessary to attach or detach the built-in device that is originally located on the front side that does not need to be attached or detached. In addition, when attaching and detaching each device, a large number of screws including the housing cover must be screwed / unscrewed. For this reason, the workability of attaching / detaching the built-in unit from the housing is remarkably reduced. Of the plurality of built-in devices, the mother board usually has a large surface area. For this reason, in the casing, at least a part of other built-in devices often overlaps the motherboard.

  SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a POS terminal apparatus that is excellent in workability for attaching and detaching a built-in device from a housing and that can be easily assembled, maintained, and repaired.

  According to the present invention, there is provided a motherboard on which an arithmetic element that performs information processing is mounted, a power supply unit, and a housing that accommodates and supports the motherboard and the power supply unit so that the motherboard and the power supply unit can be taken out. And a cover that is removably attached to the chassis, and the motherboard, the power supply unit, and the cover are each fixed to the chassis so as to be removable without a tool. .

  The POS terminal device according to the present invention is excellent in detachability from the housing of the built-in unit, and is easy to assemble, maintain, and repair.

  Further, the display unit 20 is attached to the front surface of the top cover 12T via a hinge mechanism.

  Further, as indicated by a broken line in FIG. 5C, a concave portion (slit portion) 122TF opened downward is formed inside the lower end portion of the top cover 12T on the front surface side of the housing. Similarly, as indicated by a broken line in FIG. 11A, a concave portion (slit portion) 122TR that opens downward is also formed inside the lower end portion of the top cover 12T on the rear side of the housing.

  Normally, the top cover 12T is not removed and the built-in device is not taken in and out, so the top cover 12T is fixed to the side brackets 11S and 12S2 with screws in order to improve the strength of the housing.

  The top cover 12T is made of a resin material. The top cover 12T is attached to the side brackets 11S and 12S2, the hinge mechanism is attached to the display unit 20, a recess 122TF that engages a metal claw described later on the front cover 12F, and Since a certain degree of strength is required for the recess 122TR that engages a metal claw, which will be described later, of the rear cover 12R, a metal member is provided at these locations inside the top cover 12T and is reinforced. ing.

[front cover]
The structure of the front cover 12F and the fact that the front cover 12F is detachably fixed to the base chassis 11B of the frame directly or indirectly without a tool will be described with reference to FIGS.

  Referring to FIG. 2C, the front cover 12F is made of a resin material and has a substantially square plate shape. A ventilation slit is formed in the plate surface of the front cover 12F. A metal plate having a plurality of square holes is fitted on the inner surface. The metal plate is formed with three claws 122F and two hook-like claws 123F, which will be described later, by sheet metal processing.

  Referring to FIG. 1A, a square lid is attached to the lower right of the illustrated front cover 12F. When the lid is opened or removed, a maintenance communication port such as a USB standard is provided in addition to the main power button and the reset button. Therefore, maintenance can be performed by connecting a maintenance device to the front surface of the POS terminal device. Therefore, it is extremely effective when the maintenance device cannot be connected to the back surface or side surface of the POS terminal device.

  As described above, the recess (slit portion) 122TF is formed on the front surface side of the top cover 12T that is indirectly fixed to the base chassis 11B.

  Further, as shown in FIGS. 2A and 2B, two recesses (holes) 113F are formed on the front surface of the housing of the base chassis 11B, and can be returned by a tension spring according to the operation. A movable member (sliding member) 114F that slides is provided.

  On the other hand, the front cover 12F includes three claws 122F corresponding to the concave portions 122TF of the top cover 12T and two hook-shaped claws 123F corresponding to the concave portions 113F of the movable member 114F.

  The movable member 114F of the base chassis 11B includes an operation knob 115F. The operation knob 115F is exposed below the housing when the front cover 12F is attached to the base chassis 11B. That is, it is exposed at a position that is difficult to understand at first glance. This is to prevent a person other than the service engineer who performs maintenance and inspection of the POS terminal device from inadvertently opening the front cover 12F.

  Now, when the front cover 12F is attached to the apparatus main body 10, the user inserts the claw 122F formed at the upper end of the front cover 12F into the concave portion 122TF of the top cover 12T from obliquely below, and then centers the upper end of the front cover 12F. And rotate the lower end of the front cover in a direction to press it against the housing. At this time, the two claws 123F protruding inward from the lower end of the front cover 12F are pressed against the two recesses 113F formed in the movable member 114F of the base chassis 11B. As a result, the movable member 114F slides in a direction that resists the restoring force of the tension spring, and the two recesses 113F are expanded. When the front cover 12F is further pressed, the hook surface of the claw 123F passes through the recess 113F, the movable member 114F is slid in the return direction by the tension spring, and the two recesses 113F are narrowed. As a result, as shown in FIG. 4B, the claw 123F is latched, and the front cover 12F is fixed to the housing.

  Here, when the front cover 12F is fixed to the casing by forming a tongue having elasticity by sheet metal processing at an appropriate location of the metal plate attached to the inside of the front cover 12F, By electrically connecting the metal plate and the base chassis 11B and the like, it is possible to prevent static electricity and prevent unnecessary radiation waves from entering and exiting.

  When removing the front cover 12F from the apparatus body 10, the user releases the latch of the claw 123F as shown in FIG. 4A by sliding the operation knob 115F exposed below the housing. Following this, the user rotates the front cover lower end in a direction slightly pulling it from the housing with the upper end of the front cover 12F as the center. By this operation, the claw 123F is completely extracted from the recess 113F. Thereafter, the hand is released from the operation knob 115F, and the claw 122F formed on the upper end of the front cover 12F is removed obliquely downward from the recess 122TF of the top cover 12T. Thereby, the front cover 12F is removed from the housing.

  By removing the front cover 12F from the housing, an inlet for a built-in device on the front surface of the housing appears. The power supply unit 13 can be detachably mounted using the introduction port of the built-in device on the front surface of the housing. The power supply unit 13 will be described in a second embodiment.

  The display unit 20 is normally positioned in front of the front cover 12F. However, when the front cover 12F located in the back is removed and the work in the housing is performed, the display unit 20 is configured to be retracted from the front of the cover by a hinge mechanism.

[Rear cover]
The rear cover 12R is detachably fixed to the base chassis 11B of the frame directly or indirectly without tools. The configuration for this is substantially the same as that of the front cover 12F. For this reason, a part of illustration and detailed description are omitted.

  The rear cover 12R shown in FIG. 1B, FIG. 14A and FIG. 14B, etc. is made of a resin material and has a substantially square plate shape. A ventilation slit is formed below the plate surface of the rear cover 12R. A metal plate having a plurality of square holes is fitted on the inner surface. The metal plate is formed with nails and hook-like nails described later by sheet metal processing.

  As described above, the concave portion (slit portion) 122TR is formed on the housing rear side of the top cover 12T that is indirectly fixed to the base chassis 11B.

  Further, a recess (hole) is formed on the rear surface of the housing of the base chassis 11B, and a movable member (sliding member) is slidable by a tension spring according to an operation.

  On the other hand, the rear cover 12R includes a claw corresponding to the recess 122TR of the top cover 12T and a hook-shaped claw corresponding to the recess of the movable member.

  Further, the movable member of the base chassis 11B includes an operation knob 115R as shown in FIG. The operation knob 115R is exposed below the housing when the rear cover 12R is attached to the base chassis 11B. That is, it is exposed at a position that is difficult to understand at first glance. This is to prevent a person other than the service engineer who performs maintenance and inspection of the POS terminal device, in particular, a customer at a fast food restaurant from inadvertently opening the rear cover 12R.

  Now, when attaching the rear cover 12R to the apparatus main body 10, the user inserts a claw formed on the upper end of the rear cover 12R from obliquely below into the recess 122TR of the top cover 12T, and then lowers the lower end of the rear cover with the upper end of the rear cover 12R as the center. Is rotated in a direction to press against the housing. At this time, the claw protruding inward from the lower end of the rear cover 12R is pressed against the recess formed in the movable member of the base chassis 11B. Thereby, a movable member slides in the direction which resists the restoring force of a tension spring, and a recessed part is pushed and expanded. When the rear cover 12R is further pressed, the hook surface of the claw penetrates the recess, the movable member slides in the return direction by the tension spring, and the recess becomes narrow. As a result, the claws are latched, and the rear cover 12R is fixed to the housing.

  Here, when the rear cover 12R is fixed to the casing by forming a tongue piece having elasticity by sheet metal processing at an appropriate position of the metal plate attached to the inside of the rear cover 12R, the metal plate By electrically connecting the base chassis 11B and the like to each other, it is possible to prevent static electricity and prevent unnecessary radiation waves from entering and exiting.

  When removing the rear cover 12R from the apparatus body 10, the user releases the claw latch by sliding the operation knob 115R exposed below the housing. Following this, the user rotates the rear cover lower end in a direction slightly pulling it from the housing, with the upper end of the rear cover 12R as the center. By this operation, the nail is completely extracted from the recess. Thereafter, the hand is released from the operation knob 115R, and the nail formed on the upper end of the rear cover 12R is removed obliquely downward from the recess 122TR of the top cover 12T. Thereby, the rear cover 12R is removed from the housing.

  By removing the rear cover 12R from the housing, an introduction port for the built-in device on the back surface of the housing appears. The motherboard 171 can be detachably mounted using the introduction port of the built-in device on the back of the housing. The mother board 171 will be described in a third embodiment.

  30A and 30B, the illustrated example is a twin display type including a display unit 20F on the front side of the apparatus main body 10 'and a display 20R on the back side. For this reason, the display unit 20F is positioned in front of the front cover 12F and the display unit 20R is positioned in front of the rear cover 12R. As shown in FIGS. 31A and 31B, when the front cover 12F located at the back of the display unit 20F is removed and the work in the housing is performed, the display unit 20F is retracted from the front of the cover by the hinge mechanism. When the rear cover 12R located behind the display unit 20R is removed and work is performed inside the housing, the display unit 20R is retracted from the front of the cover by a hinge mechanism. Has been.

[Side cover]
The structure of the side cover 12S and that the side cover 12S is detachably fixed to the base chassis 11B of the frame directly or indirectly without a tool will be described with reference to FIGS.

  As shown in FIG. 16B, the side cover 12S is made of a resin material and has a substantially trapezoidal plate shape. Ventilation slits are formed on the plate surface of the side cover 12S.

  As shown in FIG. 16A, nine concave portions (holes) 112S are formed in the side bracket 11S that is indirectly fixed to the base chassis 11B (only six are shown).

  Also, as shown in FIGS. 17 (a) and 17 (b) and FIGS. 18 (a) and 18 (b), two studs 113S are formed on the side surface of the base chassis 11B according to the operation. A movable member (sliding member) 114 </ b> S that slides back by a tension spring is provided.

  On the other hand, as shown in FIG. 16B, the side cover 12S is formed with nine upward claws 122S corresponding to the concave portions 112S of the side bracket 11S and concave portions corresponding to the studs 113S of the movable member 114S. And two hooks 123S.

  The movable member 114S of the base chassis 11B includes an operation knob 115S. The operation knob 115S is exposed below the housing when the side cover 12S is attached to the base chassis 11B. That is, it is exposed at a position that is difficult to understand at first glance. This is to prevent a person other than the service engineer who performs maintenance and inspection of the POS terminal device from inadvertently opening the side cover 12S.

  Now, when attaching the side cover 12S to the apparatus main body 10, the user inserts nine upward claws 122S formed on the side cover 12S from the outside into the nine concave portions 112S of the side bracket 11S, and the side cover. After 12S is brought into close contact with the side bracket 11S, the side cover 12S is slid upward. At this time, the wedge-shaped slope of the hook 123S formed at the lower end of the side cover 12S is pressed against the two studs 113S formed on the movable member 114S of the base chassis 11B. As a result, the movable member 114S slides in a direction that resists the restoring force of the tension spring, and the two studs 113S move along the slope of the hook 123S of the side cover 12S. When the side cover 12S is further slid upward, the stud 113S is disengaged from the slope of the hook 123S, the movable member 114S is slid in the return direction by the tension spring, and the two studs 113S return to the initial position. As a result, as can be seen from FIG. 18B and the like, the stud 113S is latched by the hook 123S, and the side cover 12S is fixed to the housing.

  Here, the side cover 12S is fixed to the housing by providing a metal plate inside the side cover 12S and further forming an elastic tongue piece at an appropriate position of the metal plate by sheet metal processing. Sometimes, the metal plate and the base chassis 11B and the like are electrically connected to prevent static electricity and unnecessary radiation waves.

  On the other hand, when removing the side cover 12S from the apparatus body 10, the user releases the stud 113S from the latch by the hook 123S by sliding the operation knob 115S exposed below the housing. Following this, the user slides the side cover 12S downward. By this operation, the stud 113S is completely detached from the hook 123S. Thereafter, the hand is released from the operation knob 115S, and the claw 122S formed on the side cover 12S is removed from the recess 112S of the side bracket 11S to the outside. Thereby, the side cover 12S is removed from the housing.

  By removing the side cover 12S from the housing, an inlet for the built-in device on the side surface of the housing appears. The I / O board 141 and the hard disk drives 151 and 161 can be removably mounted using the built-in device introduction port on the side of the housing. The I / O board 141 will be described in a fourth embodiment, and the hard disk drives 151 and 161 will be described in a fifth embodiment.

  As described above, the right side cover 12S toward the front of the housing has been described. However, the left side cover 12S2 of the present embodiment (FIG. 1B, FIG. 30B, FIG. 31B). ) Is screwed to the frame and is not fixed removably without tools from the frame. For this reason, illustration and detailed description are omitted.

  The second embodiment includes the configuration of the first embodiment, and further includes the following configuration.

  As described above, the power supply unit 13 retracts the display unit 20 and directly or indirectly with respect to the base chassis 11B of the frame through the introduction port on the front surface of the apparatus main body 10 (housing) that appears when the front cover 12F is removed.

It slides on the slope formed in front of the hole 117T. At this time, the tip of the rod portion of the release knob 116T is pressed in the retracted direction by the slope of the power supply bracket 11T. When the power supply holder 115T is further closed, the tip of the rod part of the release knob 116T is inserted into the hole 117T of the power supply bracket 11T, and as shown in FIGS. 5 (c) and 5 (e) and FIG. 7 (a). 115T engages with the power supply bracket 11T, and the power supply unit 13 is fixed in the power supply bracket 11T. Since the power supply bracket 11T is directly and indirectly fixed to the base chassis 11B as described above, the power supply unit 13 is fixed in the housing. Thereafter, the user connects the power supply cable led out from the power supply unit 13 to a necessary location. On the other hand, the commercial power plug cord may be inserted into the power unit 13 either before or after the power unit 13 is fixed in the housing. Thereafter, the user attaches the front cover 12F to the housing and lowers the display unit 20 in a normal direction.

  On the other hand, when the power supply unit 13 is taken out from the apparatus main body 10, the user retracts the display unit 20 as shown in FIG. 5A and removes the front cover 12F as shown in FIG. deep. Further, the user pulls out the power supply cable connected to a necessary place in the casing led out from the power supply unit 13. On the other hand, the commercial power plug cord may be removed from the power supply unit 13 at any time before or after the power supply unit 13 is removed from the housing. Thereafter, the user releases the engagement as shown in FIG. 7B by pulling up the release knob 116T engaged with the hole 117T of the power supply bracket 11T. As shown, power supply holder 115T is fully opened. At this time, since the power supply unit 13 is half accommodated in the power supply bracket 11T, it does not fall. Following this, as shown in FIG. 6B, the user rotates the other end part of the power supply unit 13 a little so as to be taken out from the power supply bracket with the one end part as the center. By this operation, one end of the power supply unit 13 is completely extracted from the claw 113T. Thereafter, the user leads out the power supply unit 13 from the introduction port on the front surface of the apparatus main body 10.

  As shown in FIG. 16 (a), the power supply unit 13 is housed and supported in the casing side by side in the front-rear direction of the motherboard 171 and the apparatus main body 10 (housing) described in detail in the third embodiment. . Furthermore, the power supply unit 13 is accommodated so as to be removable from the front side of the housing. On the other hand, the mother board 171 is housed so as to be removable from the back side of the housing. Thereby, the power supply unit 13 is accommodated in the housing so that it can be taken out separately from the mother board 171.

  The third embodiment includes the configurations of the first and second embodiments, and further includes the following configurations.

  As described above, the mother board 171 is fixed to the base chassis 11B of the frame directly or indirectly so as to be removable without tools through the introduction port on the back surface of the apparatus main body 10 (housing) that appears when the rear cover 12R is removed. The Hereinafter, this configuration will be described mainly with reference to FIGS.

  Referring to FIG. 11C, the motherboard 171 is mounted with a CPU, DRAM, RTC (Real Time Clock) battery, power receiving connector, storage device connector, standard connector, and the like. A cooling fan is attached on the CPU. The power receiving connector is mounted on the left end of the motherboard 171 in the figure, and a power supply cable connector (not shown) from the power supply unit 13 is inserted and removed in a direction perpendicular to the board surface. A plurality of standard connectors are mounted on the lower end of the motherboard 171 in the figure, and the motherboard 171 is exposed from the bottom surface of the POS terminal device when the motherboard 171 is accommodated and supported by the apparatus main body 10 (housing), and peripheral devices are provided. A cable connector (not shown) is inserted and removed in a direction parallel to the substrate surface. Note that in FIG. 11C and other figures such as FIG. 11A, the mounted items on the mother board 171 are partially different. This is because the specifications differ depending on the user and the destination. For example, in FIG. 11A and the like, a heat sink is attached on the CPU, and a type and quantity of standard connectors are different and metal brackets that cover peripheral connectors are attached. For convenience of explanation, the same reference numeral 171 is given to both motherboards.

  The mother board 171 is further formed at the right end of FIG. 11C, and has a mother board tab part 173 on which an input / output pattern of electric signals is formed, and six flanged spacers attached so as to protrude from the back surface of the board. 174 and a handle 176 attached to the substrate surface. In this example, the electric signal is a peripheral device interface signal, and its input / output pattern is electrically connected to the expansion connector described in the fourth embodiment. As will be described later, the handle 176 is used when the motherboard 171 is entirely slid while the motherboard tab 173 is inserted into and removed from a connector that receives the motherboard tab 173. Therefore, it is preferable that a single handle be provided in the vicinity of the motherboard tab portion 173 so that unnecessary moment is not applied to the motherboard tab portion 173 and the receiving connector. It is preferable to provide in a contrasting position. In the illustrated example, the handle 176 is single and is provided at a position relatively distant from the motherboard tab portion 173, which may cause an unnecessary moment. However, the handle 176 and the standard connector are arranged symmetrically around the motherboard tab portion 173, and the standard connector is a solid part and is relatively firmly soldered. Used as

  The spacer 174 is a kind of fastening member made of a resin material having elasticity such as polypropylene. As shown in FIGS. 12A and 12B, the spacer 174 includes a wedge portion, a double flange portion, and an intermediate portion between the wedge portion and the double flange portion. As shown in FIG. 12B, by using the spacer 174, the mother board 171 can be mounted at a distance from the mother board bracket 11M, which will be described in detail later, and an unnecessary electrical short circuit can be avoided. A hole is formed in the mother board 171, and the wedge part is press-fitted from the back surface of the mother board 171, and the wedge error is caught on the front surface of the mother board 171 after the press-fitting. When it is necessary to remove it, it is pressed from the front surface of the mother board 171 and removed from the back surface while pressing the spread of the wedge by using a jig or a tool or manually. The combination of the mother board 171 and the six spacers shown in FIG. 11C can be handled as the mother board unit 17 because they are detachably accommodated in the apparatus main body.

  On the other hand, the motherboard bracket 11M shown in FIG. 11B is directly attached to the base chassis 11B and indirectly using screws or the like via the side bracket 11S and the intermediate bracket 11I fixed to the base chassis 11B. It is fixed.

  Referring to FIG. 11B, the motherboard bracket 11M is formed by processing a galvanized steel sheet or the like into a sheet metal, and has a substantially flat plate shape. The motherboard bracket 11M is formed corresponding to the spacer 174 of the motherboard unit 17, and has six holes 114M having a funnel shape for holding the spacer 174 so that the spacer 174 can be removed, and as a result, a ground formed on the back surface of the motherboard 171. An elastic tongue piece integrally formed with the bracket body by sheet metal processing at a position corresponding to the pattern or ground land, and a hinge type holding the other end 175 (FIG. 11C) of the motherboard 171 releasably. And a motherboard holder 115M.

  The motherboard unit 17 having the spacer 174 attached to the motherboard 171 slides to the position where the funnel-shaped narrow portion ends after the double flange portion of the spacer 174 is inserted into the round hole portion of the hole portion 114M of the motherboard bracket 11M. Is done. The motherboard 171 that has been slid to the end position is fixed except for the movement in a direction reverse to the sliding direction. The movement in the direction in which the movement is not fixed in this manner is suppressed to some extent because the double flange portion of the spacer 174 increases the thickness of the motherboard bracket 11M. The fixing means for reliably suppressing the slide will be described later.

  The motherboard tab portion 173 shown in FIG. 11C is removably inserted into the board connector 181 mounted on the relay board 18 shown in FIG.

  On the other hand, the relay board 18 shown in FIG. 13 is indirectly fixed to the base chassis 11B via the side bracket 11S2 and the intermediate bracket 11I fixed to the base chassis 11B, as shown in FIG. ing. As shown in FIG. 13, two spacers 184 with flanges are attached to the relay substrate 18. The spacer 184 is exactly the same as the spacer 174 used for the mother board 171, and the way to attach to the relay board 18 is the same as the way to attach to the mother board 171. As can be seen from FIG. 23A, the substrate unit in which the spacer 184 is attached to the relay substrate 18 is slid along the oblique groove formed in the side bracket 11S2 at the double flange portion of the spacer 184. The front end portion of the relay board 18 in the sliding direction (two ends because it slides obliquely) comes into contact with the intermediate bracket 11I and the side bracket 11S2 cut or raised or the upper surface of the base chassis 11B. The substrate unit slid to this end position is fixed except for movement in a direction reverse to the sliding direction. This board unit is basically not screwed to the side bracket 11S2 or the like. However, since the double flange portion of the spacer 184 increases the thickness of the side bracket 11S2, the movement is restrained to some extent, and the POS terminal device can be assembled, transported, used and maintained. Since no force is applied in the direction in which the movement is not fixed with respect to the substrate unit, the substrate unit will not be displaced or fall off.

  A hinge-type motherboard holder 115M shown in FIG. 11B is configured such that the left base end in FIG. 11B rotates about a central axis parallel to the plate surface of the motherboard bracket 11M. On the other hand, at the free end of the motherboard holder 115M, a spring piece is formed at the end, and screwed out to the screw hole 117M (FIG. 15A) formed on the plate surface of the motherboard bracket 11M. A hand screw 116M that can be screwed in is incorporated so as not to fall off the motherboard holder 115M. Such screws are also referred to as SEMS (trademark or registered trademark) screws. Referring also to FIGS. 15 (a) and 14 (d), the other end 175 of the motherboard 171 is placed on the left side in the figure by closing the motherboard holder 115M and screwing the hand screw 116M into the screw hole 117M. Directional movement is restricted.

  Now, when the mother board unit 17 (mother board 171) is built in the apparatus main body 10, the user removes the rear cover 12R in advance as shown in FIGS. On the other hand, the user attaches six spacers 174 to the mother board 171 in advance and configures it as the mother board unit 17. Further, the user opens the mother board holder 115M by loosening the hand screw of the mother board bracket 11M in the housing. Thereafter, the user introduces the motherboard unit 17 from the introduction port on the back surface of the apparatus main body 10, inserts the double flange portion of the spacer 174 into the round hole portion of the hole portion 114M of the motherboard bracket 11M, and then the handle 176 and the standard. Hold the connector and slide toward the right side of the apparatus body 10 (housing) until the funnel-shaped narrow portion ends. At this time, the motherboard tab portion 173 is inserted into the board connector 181 of the relay board 18 that is vertically positioned on the right side of the motherboard bracket 11M, and electrical connection between the motherboard 171 and other built-in devices via the relay board 18 is performed. Is made. The motherboard unit 17 in this state is in a temporarily fixed state supported by the board connector 181 and the motherboard bracket 11M except for movement to the left, that is, movement in a direction in which the motherboard tab portion 173 is removed from the board connector 181. . Subsequently, the user closes the hinge-type motherboard holder 115M and screws the hand screw 116M into the screw hole 117M, whereby the other end 175 of the motherboard 171 is restricted from moving in the left direction in the figure. That is, the motherboard unit 17 is fixed on the motherboard bracket 11M as shown in FIGS. 14 (c) and 14 (d). Since the motherboard bracket 11M is directly and indirectly fixed to the base chassis 11B as described above, the motherboard unit 17 is fixed in the housing. The user connects the power supply cable led out from the power supply unit 13 to the power receiving connector of the motherboard 171. Thereafter, the user attaches the rear cover 12R to the casing.

  On the other hand, when taking out the motherboard unit 17 from the apparatus main body 10, the user removes the rear cover 12R in advance as shown in FIGS. First, the user pulls out the power supply cable connector inserted into the power receiving connector of the motherboard unit 17. Thereafter, the user loosens the hand screw of the motherboard bracket 11M in the housing and opens the motherboard holder 115M as shown in FIG. At this time, the motherboard unit 17 is not dropped because it is fixed by the motherboard bracket 11M and the board connector 181 mounted on the relay board 18. Subsequently, as shown in FIG. 15B, the user holds the entire motherboard unit 17 with the handle 176 and the standard connector so as to remove the motherboard tab 173 from the board connector 181 of the relay board 18. Slide toward the left side of the apparatus body 10 (housing). At this time, the double flange portion of the spacer 174 reaches the round hole portion of the hole portion 114M of the motherboard bracket 11M. Further, the motherboard tab portion 173 is removed from the board connector 181, and the electrical connection between the motherboard 171 and other built-in devices via the relay board 18 is also cut off. Even in this state, since the six spacers 174 are caught in the round hole portion of the hole 114M of the motherboard bracket 11M, the motherboard unit 17 is difficult to fall. Thereafter, the user derives the motherboard unit 17 from the introduction port on the back surface of the apparatus main body 10.

  As shown in FIG. 16A, the mother board 171 (mother board unit 17) is arranged in the casing side by side in the front-rear direction of the power source unit 13 detailed in the second embodiment and the apparatus main body 10 (housing). Contained and supported. Further, the mother board 171 is accommodated so as to be removable from the rear side of the housing. On the other hand, the power supply unit 13 is accommodated so as to be removable from the front side of the housing. Thereby, the mother board 171 is accommodated in the housing so as to be able to be taken out separately from the power supply unit 13.

For example, in addition to the 3.5-inch HDD shown in FIG. 27, the 2.5-inch HDD shown in FIG. 28 and a solid state drive (SSD) are appropriately selected. Of different thicknesses and various storage capacities are selected.

  Referring to FIG. 27B, the storage device holder 155 is formed by injection molding a resin material having a color such as a polymer alloy such as PC / ABS, which is easy for the user to visually recognize. Yes. In order to accommodate the storage device 151, the storage device holder 155 includes a pair of wall portions 156 opposed to each other at an interval corresponding to the width dimension of the storage device 151, a pair 156b connecting the pair of wall portions 156, A pair of lock levers 157 formed at the end of the wall portion 156 and a claw 157b formed outside the pair of lock levers 157 are integrally provided with the same material. Furthermore, for example, four metal studs 158 are attached to the inner side surfaces of the pair of wall portions 156 of the storage device holder 155 corresponding to the screw holes on the side surfaces of the storage device 151. The metal stud 158 protrudes from the inner side surface of the pair of wall portions 156, enters the screw hole portion of the storage device 151 mounted on the storage device holder 155, and contacts the screw hole portion of the storage device 151, and the funnel formed in the pair of wall portions 156 And a double flange portion that is slidably attached to the hole of the shape. Since the storage device holder 155 is made of an elastic material including the connecting portion 156b, the user can expand the distance between the pair of wall portions 156. In particular, the region close to the pair of wall portions 156 of the connecting portion 156b has a corrugated shape, and has a large amount of deflection, but is excellent in durability without causing unnecessary stress concentration. With such a configuration, when the user releases the expansion between the pair of wall portions 156 after introducing the storage device 151 between the pair of wall portions 156 where the distance between the pair of wall portions 156 is extended, the metal stud 158 is inserted into a screw hole on the side of the storage device 151, and the storage device 151 is fixed to the storage device holder 155.

  The storage device 151 mounted on the storage device holder 155 can be handled as the storage unit 15 as shown in FIG.

The metallic storage bracket 11H shown is attached. The storage bracket 11H has a pair of wall portions defining a space corresponding to the outer shape of the storage unit 15 (storage device holder 155) and one end of the pair of wall portions corresponding to the pair of claws 157b of the storage device holder 155. A pair of formed hole portions 117H and a pair of protrusions 118H projecting inward at one end of the pair of wall portions are provided. The storage bracket 11H serves as a guide when the storage unit 15 is inserted and removed from the right side surface (left side in the figure) of the apparatus main body 10 (housing) in the width direction of the housing as shown in FIG. As shown in FIG. 26A, the unit is supported when the storage unit 15 is completely inserted into the housing. When the storage unit 15 is completely inserted into the housing, the storage unit 15 is prevented from entering further by contacting the pair of protrusions 118H of the storage bracket 11H. Further, since the pair of claws 157b of the pair of lever pieces 157 of the storage device holder 155 engage with the pair of holes 117H of the storage bracket 11H, the storage unit 15 is removed from the housing unless a predetermined operation is performed. I can't do that.

  When the storage unit 15 (storage device 151) is built in the apparatus main body 10, the user operates the operation knob 115S and removes the side cover 12S in advance as can be seen from FIGS. 22 (a) and 22 (b). deep.

Thereafter, as shown in FIG. 26 (c), the user introduces the storage unit 15 from the introduction port on the right side surface (left side in the figure) of the apparatus main body 10, and the storage main body 10 ( Slide (insert) toward the left side of the housing. When the user pushes the storage unit 15 to the specified position, the claw 157b of the lock lever 157 engages with the hole 117H of the storage bracket 11H with a click feeling. Thereby, the storage unit 15 is completely accommodated in the housing and fixed. That is, the storage unit 15 is fixed to the side bracket 11S2, the intermediate bracket 11I, and the side bracket 11S via the storage bracket 11H. Since these brackets are directly and indirectly fixed to the base chassis 11B as described above, the storage unit 15 is fixed in the housing. The user inserts at least the cable connector derived from the motherboard 171 out of the motherboard 171 and the power supply unit 13 into the connector 151 c of the storage device 151. Since the pair of lock levers 157 are opposed to each other on the outer side than the connector 151c, the insertion / extraction of the mating connector to the connector 151 is not hindered. Thereafter, the user attaches the side cover 12S to the casing.

  On the other hand, when taking out the storage unit 15 from the apparatus main body 10, the user removes the side cover 12S in advance and puts it in the state shown in FIG. Next, the user pulls out the cable connector connected to the connector 151c of the storage device 151. Then, the user releases the engagement of the pair of claws 157b with respect to the pair of holes 117H of the storage bracket 11H by pinching the pair of lock levers 157 so that the facing interval is narrow, Pull out the storage unit 15 as shown in c). Thereafter, the user leads out the storage unit 15 from the inlet on the right side surface of the apparatus main body 10.

  As described above, the storage unit according to the present invention can use storage devices having different specifications according to the user's needs. As an example, a 2.5 inch HDD can be used instead of the 3.5 inch HDD.

  Referring to FIG. 28 (a), the storage device 161 is a 2.5-inch HDD, and similarly to the storage device 161 that is a 3.5-inch HDD, screw holes are formed on both sides thereof, and The connector 161c is provided on one end face thereof.

  Referring to FIG. 28 (c), the storage device holder 165 is formed by injection molding a resin material having a color such as a polymer alloy such as PC / ABS that is easy for the user to visually recognize. Yes. The storage device holder 165 has an interval corresponding to the width dimension of the storage device 161 in order to accommodate the storage device 161 or the storage device 161 on which the heat sink 163 shown in FIG. A pair of opposing wall portions 166, 166b connecting the pair of wall portions 166, a pair of lock levers 167 formed at the ends of the pair of wall portions 166, and an outer side of the pair of lock levers 167. The claws 167b are integrally made of the same material.

  In particular, the storage device holder 155 for the 3.5-inch HDD described above (FIG. 27 (b)) is different from (1) a protrusion for holding the heat sink 163 is formed inside the pair of wall portions. And (2) a point where the pair of wall portions 166 has a double structure with a space, and (3) a point where an extension fitting to be described later is provided.

  The storage device holder 165 is compatible with a 2.5-inch HDD in the storage device housing portion, but has the same external dimensions and shape as the storage device holder 155 for a 3.5-inch HDD. As a result, the POS terminal apparatus according to the present invention can use the common storage bracket 11H (FIGS. 27D and 28E) regardless of the size of the storage device to be accommodated, and it is necessary to replace this bracket. There is no.

  Furthermore, for example, four metal studs 168 are attached to the inner side surfaces of the pair of wall portions 166 of the storage device holder 165 corresponding to the screw holes on the side surfaces of the storage device 161. The metal stud 168 is the same as the metal stud 158 shown in FIG. 27B, and protrudes from the inner surface of the pair of wall portions 166 in the same manner as the metal stud 158, and is mounted on the storage device holder 165. The device 161 includes a portion that enters and contacts the screw hole portion of the device 161, and a double flange portion that is slidably attached to the funnel-shaped hole portion formed in the pair of wall portions 166.

  However, since the pair of wall portions 166 has a double structure, the back surface (outer surface) of the metal stud 168 is not exposed on the outer surface of the pair of wall portions 166. For this reason, in this example, an extension fitting 169 shown in FIG. 29 is provided outside each metal stud 168. Referring to FIG. 29, the extension fitting 169 has a spring property, and has an inner end portion 169i that contacts the back side surface of the metal stud 168, and an outer end portion exposed from the pair of wall portions 166 to contact the storage bracket 11H. 169o. As a result, even the small storage device 161 can be electrically connected to the housing frame via the storage bracket 11H when inserted into the POS terminal device.

  Further, since the storage device holder 165 is made of an elastic material including the connecting portion 166b, the user can expand the distance between the pair of wall portions 166. In particular, the region close to the pair of wall portions 166 of the connecting portion 166b has a corrugated shape, and has a large amount of deflection, but is excellent in durability without causing unnecessary stress concentration. With such a configuration, when the user introduces the storage device 161 between the pair of wall portions 166 in which the distance between the pair of wall portions 166 is extended and releases the expansion between the pair of wall portions 166, the metal stud 168 is removed. Is inserted into the screw hole on the side of the storage device 161, and the storage device 161 is fixed to the storage device holder 165.

  The storage device 161 is mounted on the storage device holder 165 shown in FIG. 28C together with the heat sink 163 shown in FIG. 28B, whereby the storage unit 16 shown in FIG. Can be handled as

  Since the storage device holder 165 has the same size and shape as the storage device 155, the storage unit 16 can be accommodated and removed from the POS terminal by the same operation as the storage unit 15. Therefore, the description is omitted.

  As shown in FIG. 16A, the storage device 151 or 161 (storage unit 15 or 16) includes the motherboard 171 described in detail in the third embodiment in the front-rear direction of the apparatus main body 10 (housing), It is accommodated and supported between the power supply unit 13 described in detail in the second embodiment.
