[Figure 11] FIG. 11 is a side view of the electronic register shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment in which the present invention is applied to an electronic register will be described with reference to FIGS. As shown in Figures 1 to 3, this electronic cash register has an equipment case 1. This equipment case 1 has a lower case 2 and an upper case 3, which are formed into a substantially box-like shape.

[0012] As shown in Figures 1 to 3, the lower case 2 includes a bottom plate 2a and a pair of side plate portions 2b standing on both sides of the bottom plate portion 2a except for the rear end portion, which are integrally formed from synthetic resin. In this case, legs 2c are provided at the four corners of the lower surface of the bottom plate portion 2a. The upper case 3 includes a case main body portion 4 disposed on the lower case 2 and a register case portion 5 protruding from the case main body portion 4, which are integrally formed from synthetic resin.

[0013] As a result, in the device case 1, as shown in Figures 1 to 3, the lower case 2 and the case main body 4 of the upper case 3 form a drawer case 6, which is the drawer main body of the drawer device. This drawer case 6 is provided with a first opening 6a that is open on the front side (the right side in Figure 3), and is configured so that the drawer section 7 is stored inside so that it can be pulled out. In this case, the case main body 4 of the upper case 3 is formed in a substantially rectangular box shape that is open on the bottom side.

[0014] 1 to 3, the upper surface of the rear side of the case main body 4 is inclined upward toward the rear so that the rear end (left end in FIG. 2) is higher than the front end (right end in FIG. 2). Therefore, the case main body 4 is configured so that, with the upper surface of the rear side inclined upward toward the rear, it is placed on the upper part of the pair of side plate parts 2b of the lower case 2, and the rear end part is placed on the bottom plate part 2a.

[0015] As shown in Figures 1 to 3, the register case portion 5 of the upper case 3 is formed in an approximately rectangular box shape that is open on the bottom, with its front-to-back length being short, approximately 2 / 3 of the front-to-back length of the case main body portion 4, and its left-to-right length perpendicular to the front-to-back direction being slightly shorter than the left-to-right length of the case main body portion 4.

[0016] 1 to 3, the register case part 5 is provided on the rear side of the case body part 4 in a state of being inclined upward toward the rear, except for the front side and both sides of the case body part 4. Therefore, the register case part 5 is provided such that the front side rising surface 5a and the rear side rising surface 5b are inclined toward the front and are parallel to each other.

[0017] 1 to 3, the rear rising surface 4c of the case main body 4 is inclined at the same angle as the rear rising surface 5b of the register case 5. The case main body 4 has a flat mounting surface 4a on the top surface located forward of the register case 5. A tray recess 4b for placing small items such as writing implements is provided in the mounting surface 4a in front of the keyboard unit 8 described below.

[0018] 1 to 3, the register case part 5 has a front rising surface 5a that protrudes above the mounting surface 4a of the case body part 4 and is formed in a stepped shape between the mounting surface 4a of the case body part 4 and the front rising surface 5a of the register case part 5. The front rising surface 5a of the register case part 5 is inclined at an inclination angle of, for example, about 15° so that its upper side protrudes toward the front of the case body part 4 and its lower side bites into the register case part 5.

[0019] As shown in Figs. 1 to 3, the register case 5 is provided with a keyboard section 8, a panel section 9, and a printer section 10. The keyboard section 8 is used to input and register information such as sales data, and is provided with various keys required for settlement such as a numeric keypad, calculation keys, a registration key, and a print key, and is located on the right front side of the upper surface of the register case 5. In this case, a communication section 12 is provided below the keyboard section 8 for performing wireless communication such as Bluetooth (registered trademark) with a mobile terminal 11, which will be described later.

[0020] 1, the panel unit 9 has a locking unit 9a for locking and unlocking the electronic register, and is located behind the keyboard unit 8 on the top surface of the register case unit 5. The printer unit 10 prints information such as sales data entered on the keyboard unit 8 onto recording paper 13 and issues a receipt from an outlet 14, as shown in FIGS. 1 to 3, and is located to the left of the keyboard unit 8 and panel unit 9 on the register case unit 5.

[0021] 1 to 3, the upper case 3 includes a mounting portion 15 which is a platform for mounting the mobile terminal 11. The mounting portion 15 includes a first support portion 16 which engages one end portion 11a of the mobile terminal 11, and a second support portion 17 which supports the back surface of the mobile terminal 11 on the other end portion 11b side.

[0022] 1 and 4, the first support portion 16 is a substantially V-shaped groove including an inclined surface 16a with which the back surface of one end 11a of the mobile terminal 11 is placed in contact, and an abutment surface 16b with which the one end 11a of the mobile terminal 11 abuts. The first support portion 16 is formed on the left side of the mounting surface 4a located on the front side of the case main body 4, that is, on the front end side of the mounting surface 4a corresponding to the front of the printer unit 10, and is longer than the length of the mobile terminal 11 in the short side direction (width direction) perpendicular to the longitudinal direction.

[0023] 1 to 4, the second support portion 17 is provided at a higher position than the first support portion 16, and is provided on the front end portion of the printer portion 10 in the register case portion 5 with which the other end portion 11b of the mobile terminal 11 is placed in contact, with the extension line in the inclination direction of the inclined surface 16a of the first support portion 16 as a tangent line. As a result, the mobile terminal 11 is placed at an inclination angle θ1 within a range of 20° to 30°, preferably about 25°, so that the second support portion 17 side is higher, by the first support portion 16 and the second support portion 17.

[0024] 1 to 4, when the portable terminal 11 is placed at an angle on the placement section 15 by the first support section 16 and the second support section 17, a space 18 is formed between the front rising surface 5a of the register case section 5 corresponding to the printer section 10 and the placement surface 4a of the case main body section 4. In this case, when one end section 11a of the portable terminal 11 is engaged with the first support section 16 and the back surface of the other end section 11b side is supported by the second support section 17, the other end section 11b side of the portable terminal 11 is positioned so as not to reach the discharge outlet 14 of the printer section 10 and not to block the discharge outlet 14.

[0025] 1 to 4, the upper surface of the printer unit 10 is inclined at an inclination angle θ2 of, for example, about 10°, which is smaller than the inclination angle θ1 of the mobile terminal 11 that is inclined and arranged by the first support portion 16 and the second support portion 17. Therefore, the discharge opening 14 of the printer unit 10 is not blocked by the mobile terminal 11 even if the other end portion 11b side of the mobile terminal 11 is arranged above the discharge opening 14.

[0026] 1 to 4, the upper surface of the printer unit 10 is inclined at an inclination angle θ2 (θ2<θ1) that is smaller than the inclination angle θ1 of the mobile terminal 11 that is arranged at an incline by the first support portion 16 and the second support portion 17. Therefore, even if the other end portion 11b side of the mobile terminal 11 is arranged above the discharge opening 14, a gap that expands toward the rear of the mobile terminal 11 is provided between the upper surface of the printer unit 10 and the rear surface of the mobile terminal 11, and the recording paper 13 discharged from the discharge opening 14 is sent out through this gap.

[0027] As shown in Figures 3 and 4, the printer unit 10 is equipped with a recording paper storage section 20 that stores rolled recording paper 13, a printing section 21 that prints information such as sales data on the recording paper 13 stored in the recording paper storage section 20, an outlet 14 through which the recording paper 13 printed by the printing section 21 is discharged, a printer cover 22 which is an opening / closing cover that opens and closes the second opening 20a of the recording paper storage section 20, and an opening button 23 for opening the printer cover 22.

[0028] In this case, as shown in Figures 3 and 4, the printing unit 21 is equipped with a print head 21a and a platen roller 21b, and is configured to print information such as sales data on the recording paper 13 while the print head 21a presses the recording paper 13 against the platen roller 21b with the recording paper 13 sandwiched between them.

[0029] 3 and 4, the print head 21a is provided on the inside of the front edge of the second opening 20a of the recording paper storage unit 20. The platen roller 21b is provided on the underside of the front end of a cover body 24 (described later) of the printer cover 22 when the second opening 20a of the recording paper storage unit 20 is closed, and is configured to face the print head 21a in close proximity.

[0030] 3 and 4, the ejection port 14 is provided in a position that straddles the front edge of the second opening 20a of the recording paper storage unit 20 and the front end of a cover body 24 (described later) of the printer cover 22 when the second opening 20a of the recording paper storage unit 20 is closed, and corresponds to the print head 21a and platen roller 21b of the printing unit 21. In this case, too, the ejection port 14 is provided so as not to be blocked by the other end 11b of the mobile terminal 11 on the second support part 17 side when the mobile terminal 11 is supported by the first support part 16 and the second support part 17.

[0031] As shown in Figures 3 to 9, the printer cover 22 comprises a cover body 24 which opens and closes the second opening 20a of the recording paper storage section 20 provided in the printer section 10 of the register case section 5, a rotating holding mechanism 25 which rotatably holds the cover body 24, a release mechanism 26 which releases the hold of the cover body 24 by the rotating holding mechanism 25 when the second opening 20a of the recording paper storage section 20 is opened and in the fully open upright position, and a holding mechanism 27 which holds the cover body 24 in the upright position when the hold of the cover body 24 by the rotating holding mechanism 25 is released by the release mechanism 26.

[0032] As shown in Figures 4 to 9, the rotational holding mechanism 25 comprises a pair of arm portions 28 provided on the rear side (left side in Figure 4) of the underside of the cover body 24 when the second opening 20a of the recording paper storage section 20 is covered and inserted into the upper case 3 through the second opening 20a of the recording paper storage section 20, a pair of holding shafts 29 provided in the upper case 3 corresponding to the pair of arm portions 28 inserted into the upper case 3, and a pair of bearing portions 30 provided at each inner end of the pair of arm portions 28 and respectively rotatably held on the pair of holding shafts 29 in the recording paper storage section 20.

[0033] As shown in Figures 4 to 9, each of the pair of arm portions 28 includes a first arm 28a extending from the underside of the cover body 24 through the second opening 20a into the upper case 3 when the second opening 20a of the recording paper storage section 20 is covered, and a second arm 28b extending from the inner end of this first arm 28a toward a retaining shaft 29 provided on the inner surface of the rear side within the upper case 3.

[0034] 6 to 9, the pair of holder shafts 29 are provided between each pair of guide ribs 34a of a pair of guide sections 34 (described later) provided on the inner surface on the rear side within the upper case 3 so as to correspond to the rear ends of the second arms 28b of the pair of arm sections 28. The pair of bearing sections 30 have shaft holes 30a in which the pair of holder shafts 29 are rotatably arranged, and are provided at the rear ends of the second arms 28b corresponding to the pair of holder shafts 29.

[0035] As shown in Figures 6 to 9, the release mechanism 26 is configured to release the hold of the cover body 24 by the rotating holding mechanism 25 when the cover body 24 held by the rotating holding mechanism 25 is in a fully open state in which the cover body 24 stands up and opens the second opening 20a of the recording paper storage section 20, and the cover body 24 rotates in the opening direction due to an external force greater than the holding force of the rotating holding mechanism 25.

[0036] That is, as shown in Figures 6 to 9, this release mechanism 26 is provided with a pair of fulcrum abutment portions 31 that abut against the edge of the second opening 20a when the cover body 24 rotates around a pair of retaining shafts 29 to open the second opening 20a of the recording paper storage section 20 and stand up fully open, a pair of cutout portions 32 that allow the pair of retaining shafts 29 to be removably inserted into each of the shaft holes 30a of the pair of bearing portions 30, and a pair of notches 33 that facilitate elastic deformation of the pair of cutout portions 32 and the pair of shaft holes 30a so as to spread them apart.

[0037] 6 to 9, the pair of fulcrum abutment portions 31 are provided at locations on the cover body 24 side of each second arm 28b of the pair of arm portions 28. With this, the release mechanism 26 is configured such that when the cover body 24 in the fully open state in which the second opening 20a of the recording paper storage portion 20 is opened and stands upright is rotated by an external force greater than the holding force of the rotation holding mechanism 25, the pair of arm portions 28 rotate about the pair of fulcrum abutment portions 31 and the pair of holding shafts 29 are released from the respective shaft holes 30a of the pair of bearing portions 30 through the pair of cutout portions 32.

[0038] As shown in Figures 8 and 9, when the release mechanism 26 has disengaged the pair of retaining shafts 29 from the respective shaft holes 30a of the pair of bearing portions 30 through the pair of cutout portions 32, the retaining mechanism 27 is configured to hold the cover body 24 upright at two points: a first abutment point P1 where the lower end portion 24a of the cover body 24 abuts against the rear rising surface 5b of the register case portion 5, and a second abutment point P2 where each first arm 28a of the pair of arm portions 28 abuts from above against the rear edge portion of the second opening 20a of the recording paper storage portion 20.

[0039] As shown in Figures 8 and 9, the printer cover 22 has a fully open state in which the cover body 24 opens the second opening 20a of the recording paper storage section 20 and stands up, and when the rotational retention by the rotational retention mechanism 25 is released, the cover body 24 is held upright by the retention mechanism 27 in a first release state in which it is held at two points, and a second release state in which, when the cover body 24 is rotated further in the opening direction by an external force in this first release state, the cover body 24 detaches from the printer section 10 of the register case section 5.

[0040] In this case, the notch 32 of the release mechanism 26 is formed at a position where the retaining shaft 29 can be removed from the shaft hole 30a of the bearing part 30 when the cover body 24 is further rotated in the opening direction from the fully open state where the second opening 20a is opened, as shown in Fig. 8. That is, the notch 32 is provided from the shaft hole 30a of the bearing part 30 in which the retaining shaft 29 is disposed to the end face of the second arm 28b which is the outer periphery of the bearing part 30 when the cover body 24 is in the upright state. The notch 32 is formed at an incline so that the notch width on the side closer to the shaft hole 30a is slightly smaller than the outer diameter of the retaining shaft 29, and the notch width on the end face side of the second arm 28b which is the side farther from the shaft hole 30a is slightly larger than the outer diameter of the retaining shaft 29.

[0041] As shown in FIG. 8, the cutout portion 33 is intended to facilitate elastic deformation of the cutout portion 32 and the axial hole 30a by expanding the notch width of the cutout portion 32 and the inner diameter of the axial hole 30a when the retaining shaft 29 is inserted through the cutout portion 32, and is provided in a portion of the bearing portion 30 located opposite the cutout portion 32, i.e., on the inner periphery of the axial hole 30a.

[0042] That is, as shown in FIG. 8, when the retaining shaft 29 is inserted through the cutout portion 32 and into the axial hole 30a, the cutout width of the cutout portion 32 and the inner diameter of the axial hole 30a are gradually expanded by the cutout portion 33, and the bearing portion 30 is configured to elastically return to its original shape and retain the retaining shaft 29 when the retaining shaft 29 is fitted into the axial hole 30a.

[0043] As shown in Figures 8 and 9, when the retaining shaft 29 is inserted through the cutout portion 32 from within the axial hole 30a against the retaining force, the notch width of the cutout portion 32, which is smaller than the outer diameter of the retaining shaft 29, and the inner diameter of the axial hole 30a are rapidly expanded by the cutout portion 33, which facilitates elastic deformation, so that the retaining shaft 29 can be inserted through the cutout portion 32 and removed from the axial hole 30a.

[0044] 7 and 8, a pair of guide sections 34 are provided within the recording paper storage section 20 to guide the pair of bearing sections 30 provided on the pair of arm sections 28 to the pair of holder shafts 29. Each of the pair of guide sections 34 has a pair of guide ribs 34a provided along the up-down direction on the inner surface on the rear side within the upper case 3, and the holder shaft 29 is provided between the pair of guide ribs 34a.

[0045] As a result, when the cover body 24 is in an upright position and each second arm 28b of the pair of arm portions 28 is inserted into the upper case 3 through the second opening 20a of the recording paper storage section 20, as shown in Figures 7 and 8, the pair of guide portions 34 are configured to move the pair of bearing portions 30 in the vertical direction while guiding them with the pair of bearing portions 30 positioned between each pair of guide ribs 34a in the pair of guide portions 34.

[0046] 7 and 8, the pair of guide parts 34 are configured such that, with the pair of bearing parts 30 disposed between each pair of guide ribs 34a, the pair of bearing parts 30 are moved in the vertical direction to bring each of the cutout parts 32 of the pair of bearing parts 30 into correspondence with the pair of retaining shafts 29. As a result, the pair of retaining shafts 29 are configured to be fitted into each of the shaft holes 30a of the pair of bearing parts 30 by being inserted through the pair of cutout parts 32.

[0047] 1 and 4 to 6, the opening button 23 of the printer cover 22 is a push button provided on the left front side of the top surface of the printer unit 10 of the register case unit 5. This opening button 23 is configured to press one end 35a of an opening lever 35 provided inside the printer unit 10 when pressed from above. In this case, the opening lever 35 is configured to swing up and down around a fulcrum shaft 35c provided in the middle of the opening lever 35.

[0048] As a result, as shown in Figures 4 to 6, the printer cover 22 is configured such that one end 35a of the opening lever 35 is pushed from above by the opening button 23, causing the opening lever 35 to swing up and down around the fulcrum shaft 35c, and the other end 35b of the opening lever 35 is pushed up, whereby the pushed-up other end 35b pushes up the cover body 24, thereby opening the second opening 20a of the recording paper storage section 20.

[0049] In this case, when the printer cover 22 is in a fully open state in which the cover body 24 opens the second opening 20a of the recording paper storage unit 20 and stands up, as shown in Fig. 6, the cover body 24 stands upright and is positioned behind the rear of the rear of the second opening 20a. That is, the rear rising surface 5b of the register case unit 5 located in the printer unit 10 has its upper side inclined forward. Therefore, the cover body 24 in the upright state is configured to stand upright and inclined slightly backward from the state perpendicular to the device case 1.

[0050] 9, in the first release state, the printer cover 22 is released from rotational hold by the rotational hold mechanism 25, and is configured so that the cover body 24 is held and stands at two points: a first abutment point P1 where the lower end 24a of the cover body 24 abuts against the rear rising surface 5b of the register case section 5 located at the rear of the recording paper storage section 20, and a second abutment point P2 where each first arm 28a of the pair of arm sections 28 abuts from above against the edge of the second opening 20a of the recording paper storage section 20. Therefore, in the first release state, the printer cover 22 can be easily removed from the printer section 10 by simply lifting the cover body 24.

[0051] Furthermore, when the printer cover 22 is in the first release state shown in FIG. 9 and the cover body 24 is rotated further in the opening direction by an external force, the cover body 24 rotates about the lower end 24a of the cover body 24 at the first abutment point P1 that abuts against the rear raised surface 5b of the register case section 5 as a fulcrum, and each second arm 28b of the pair of arm sections 28 overcomes the edge of the second opening 20a of the recording paper storage section 20, thereby entering a second release state in which the cover body 24 detaches to the rear of the printer section 10.

[0052] Meanwhile, as shown in Figures 10 and 11, the drawer section 7 in the drawer case 6 of the drawer device of the equipment case 1 is formed so that the front panel 7a located on the drawer side tilts forward from the bottom surface of the drawer case 6 in the drawer direction of the drawer section 7 when blocking the first opening 6a of the drawer case 6.

[0053] 10 and 11, the drawer section 7 in the drawer case 6 has a front panel 7a located on the drawer side formed on an inclined surface inclined at an inclination angle, for example, an inclination angle θ3 of 15° (see FIG. 2), which makes it difficult for the front panel 7a to be seen from the line of sight of the operator when pulling out the drawer section 7. In addition, both sides of the first opening 6a of the drawer case 6 located on the side from which the drawer section 7 is pulled out, i.e., the front ends of the pair of side panels 2b of the lower case 2, are inclined at the same inclination angle θ3 as the front panel 7a of the drawer section 7.

[0054] As shown in Figures 10 and 11, a plurality of money storage sections 36 are provided inside the drawer section 7. These multiple money storage sections 36 store banknotes and coins by denomination, with a plurality of coin storage sections 36a arranged at the front side of the drawer section 7 and a plurality of banknote storage sections 36b arranged at the rear side of the drawer section 7. In this case, the multiple money storage sections 36 are formed integrally with the drawer section 7.

[0055] This makes the overall thickness of the drawer section 7 thinner than when the multiple money storage sections 36 are provided separately, as shown in Figures 10 and 11. Also, the multiple money storage sections 36 corresponding to the front panel 7a of the drawer section 7, i.e., the front inner surfaces of the multiple coin storage sections 36a, are inclined at the same inclination angle θ3 as the front panel 7a of the drawer section 7. Furthermore, the multiple banknote storage sections 36b at the rear side of the drawer section 7 each have a paper presser 36c for pressing down stored banknotes.

[0056] Next, the operation of such an electronic register will be described. When using this electronic register, first, the locking portion 9a of the panel portion 9 is unlocked. In this state, the mobile terminal 11 is placed on the placement portion 15, which is a placement stand of the upper case 3. At this time, one end portion 11a of the mobile terminal 11 is engaged with the first support portion 16 of the placement portion 15, and the other end portion 11b of the mobile terminal 11 is supported by the second support portion 17 on the placement portion 15, which is the register case portion 5.

[0057] In this case, when one end 11a of mobile terminal 11 is engaged with first support portion 16 of mounting portion 15, one end 11a of mobile terminal 11 abuts against abutment surface 16b of first support portion 16 with the back surface of one end 11a of mobile terminal 11 being placed in contact with inclined surface 16a of first support portion 16. As a result, one end 11a of mobile terminal 11 is engaged with first support portion 16 of mounting portion 15 in a stable state.

[0058] Also, the other end 11b of the mobile terminal 11 is supported by the second support part 17 on the register case part 5. At this time, the second support part 17 is provided on the front end part of the printer part 10 in the register case part 5, which is located at a higher position than the first support part 16, and the other end part 11b side on the back surface of the mobile terminal 11 is placed in contact with the second support part 17 with the extension line in the tilt direction of the inclined surface 16a of the first support part 16 as a tangent. As a result, the mobile terminal 11 is placed at an inclination angle θ1 of about 25° so that the second support part 17 side is higher due to the first support part 16 and the second support part 17.

[0059] Therefore, the mobile terminal 11 is stably placed on the placement unit 15 in a state in which the mobile terminal 11 is tilted by the first support portion 16 and the second support portion 17 so that the second support portion 17 side is higher. As a result, even if the mobile terminal 11 is placed in a tilted state by the first support portion 16 and the second support portion 17, the mobile terminal 11 can be operated smoothly, and does not get in the way of the printer portion 10 and the keyboard portion 8, allowing the printer portion 10 to print smoothly and allowing the keyboard portion 8 to perform input operations smoothly.

[0060] Furthermore, in this mobile terminal 11, wireless communication such as Bluetooth (registered trademark) is performed between the electronic register and the mobile terminal 11 by a communication unit 12 provided below the keyboard unit 8 of the register case unit 5. In this state, a space 18 is formed between the front rising surface 5a of the register case unit 5 corresponding to the printer unit 10 and the mounting surface 4a of the case body unit 4.

[0061] Therefore, the space 18 allows the portable terminal 11 to be placed in a tilted and stable state, and since both sides of the portable terminal 11 corresponding to the space 18 can be easily grasped, the attachment and detachment of the portable terminal 11 can be improved. In addition, it becomes possible to place small items such as writing implements on the placement surface 4a of the case main body 4 located in the space 18.

[0062] In this case, the other end 11b of the mobile terminal 11 does not reach the discharge outlet 14 of the printer unit 10, so the mobile terminal 11 is arranged so as not to block the discharge outlet 14 for the recording paper 13 in the printer unit 10. In this case, the other end 11b of the mobile terminal 11 may be arranged above the discharge outlet 14.

[0063] In this way, the portable terminal 11 can be easily and satisfactorily placed on the mounting portion 15 by simply engaging one end 11a with the first support portion 16 of the mounting portion 15 and supporting the other end 11b of the portable terminal 11 on the second support portion 17 on the front end of the printer unit 10 in the register case portion 5, which is the mounting portion 15. The portable terminal 11 can also be easily and simply removed from the mounting portion 15 by simply lifting both sides in the short direction perpendicular to the long direction. This gives the portable terminal 11 good attachment and detachment operability.

[0064] Next, a case where sales data is registered while the mobile terminal 11 is placed on the placement section 15 will be described. In this case, first, sales data and other information is entered by operating the keys on the keyboard 8 of the register case 5. Then, the registration key is operated to register the sales data and other information, and the print key is operated. Then, the printing section 21 of the printer 10 prints the sales data and other information on the recording paper 13, and the printed recording paper 13 is discharged from the discharge port 14 and issued as a receipt.

[0065] That is, when the printing unit 21 prints information such as sales data on the recording paper 13, the recording paper 13 wound in a roll stored in the recording paper storage unit 20 is fed between the print head 21a and the platen roller 21b of the printing unit 21, and in this state, the print head 21a presses the recording paper 13 against the platen roller 21b while printing information such as sales data on the recording paper 13. This printed recording paper 13 is discharged from the discharge port 14 of the printer unit 10.

[0066] At this time, the other end 11b of the portable terminal 11 placed on the placement section 15 has not reached the discharge outlet 14 of the printer section 10, so the discharge outlet 14 of the printer section 10 is not blocked by the portable terminal 11. Therefore, the printed recording paper 13 is discharged smoothly upward from the discharge outlet 14. In this case, even if the other end 11b of the portable terminal 11 is positioned above the discharge outlet 14, the recording paper 13 discharged from the discharge outlet 14 is discharged without causing a paper jam.

[0067] That is, the inclination angle θ2 of the upper surface of the printer unit 10 is inclined at a smaller inclination angle (θ2<θ1) than the inclination angle θ1 of the mobile terminal 11 arranged at an incline by the first support part 16 and the second support part 17. Therefore, even if the other end 11b side of the mobile terminal 11 is arranged above the discharge port 14, a gap that expands toward the rear is provided between the upper surface of the printer unit 10 and the back surface of the mobile terminal 11, and this gap allows the recording paper 13 discharged from the discharge port 14 to be sent out smoothly without causing a paper jam.

[0068] In this way, when the recording paper 13 is issued as a receipt and the recording paper 13 runs out and needs to be replaced, the opening button 23 of the printer unit 10 is operated to open the printer cover 22. That is, when the opening button 23 is operated, the opening button 23 pushes down one end 35a of the opening lever 35, causing the opening lever 35 to rotate around the fulcrum shaft 35c, and the other end 35b of the opening lever 35 pushes up the cover body 24 of the printer cover 22. This opens the cover body 24, opening the second opening 20a of the recording paper storage unit 20, and new recording paper 13 can be stored in the recording paper storage unit 20 through this opened second opening 20a.

[0069] At this time, the pair of bearings 30 provided on the pair of arms 28 of the rotation holding mechanism 25 in the printer cover 22 are rotatably held by the pair of holding shafts 29 inside the upper case 3, so that the pair of arms 28 rotate around the pair of holding shafts 29 as fulcrums. Accordingly, the cover body 24 rotates and stands up. In this state, with the pair of bearings 30 supported by the pair of holding shafts 29, that is, with the pair of holding shafts 29 fitted into the pair of shaft holes 30a, the pair of fulcrum abutment portions 31 of the release mechanism 26 abut against the edge of the second opening 20a of the recording paper storage section 20.

[0070] As a result, the cover body 24 stands up stably above the printer unit 10. Also, when the cover body 24 is positioned rearward of the rear of the second opening 20a, it stands up tilted slightly rearward from the perpendicular state to the device case 1. This also prevents the cover body 24 from accidentally rotating in the closing direction, and the cover body 24 stands up stably above the printer unit 10. In this state, the recording paper 13 wound in a roll is inserted and positioned in the recording paper storage unit 20 through the second opening 20a. Thereafter, when the cover body 24 is rotated in the closing direction, the second opening 20a of the recording paper storage unit 20 is blocked by the cover body 24.

[0071] At this time, the platen roller 21b provided on the cover body 24 approaches and faces the print head 21a of the printer unit 10. Also, at this time, the discharge port 14 for discharging the recording paper 13 is provided corresponding to the print head 21a and platen roller 21b of the print unit 21, straddling the cover body 24 and the printer unit 10.

[0072] Incidentally, when the cover body 24 is rotated further in the opening direction from the fully open state in which the cover body 24 stands up due to an external force greater than the holding force of the rotation holding mechanism 25, the cover body 24 rotates by the principle of a lever, with a pair of fulcrum abutment portions 31 of the release mechanism 26 abutting on the edge of the second opening 20a of the recording paper storage section 20 as fulcrums, and the pair of holding shafts 29 disengage from the pair of shaft holes 30a through the pair of cutout portions 32. That is, the cutout portion 32 is formed so that the cutout width on the side closer to the shaft hole 30a is slightly smaller than the outer diameter of the holding shaft 29, and the cutout width on the end face side of the second arm 28b, which is the side farther from the shaft hole 30a, is slightly larger than the outer diameter of the holding shaft 29.

[0073] Therefore, when the holding shaft 29 is inserted through the notch 32, the notch 32 and the shaft hole 30a of the bearing portion 30 are elastically deformed and pushed open by the notch 33 provided in the bearing portion 30. In other words, when the holding shaft 29 is to be removed from the shaft hole 30a, the notch 33 facilitates elastic deformation of the holding shaft 29 so as to push open the shaft hole 30a and the notch 32, and the holding shaft 29 is removed from the shaft hole 30a through the notch 32. This brings the printer cover 22 into the first release state.

[0074] In this first release state, the cover body 24 is held in an upright state by the holding mechanism 27. That is, the holding mechanism 27 holds the cover body 24 in an upright state at two points: a first abutment point P1 where the lower end 24a of the cover body 24 abuts against the rear rising surface 5b of the register case portion 5, and a second abutment point P2 where each of the first arms 28a of the pair of arm portions 28 abuts against the rear edge of the second opening 20a of the recording paper storage portion 20.

[0075] Therefore, even if the cover body 24 rotates in the open direction due to an external force greater than the holding force of the rotation holding mechanism 25, the printer cover 22 will not be damaged, and the cover body 24 is well held at two points, the first abutment point P1 and the second abutment point P2, by the holding mechanism 27. As a result, the printer cover 22 will not fall off the upper case 3 even if the holding shaft 29 comes out of the shaft hole 30a of the bearing portion 30.

[0076] Therefore, in this first release state, not only is printer cover 22 easy to handle, but printer cover 22 does not get in the way and does not interfere with the operation of printer unit 10. Also, in this first release state, printer cover 22 can be easily removed from printer unit 10 by simply lifting cover body 24.

[0077] Furthermore, when the cover body 24 receives an external force and rotates further in the opening direction in this first release state, the cover body 24 separates from the printer unit 10 of the register case unit 5 to enter the second release state. That is, when the cover body 24 receives an external force and rotates further in the opening direction in the first release state, the cover body 24 rotates about the lower end portion 24a of the cover body 24 at the first abutment point P1 that abuts against the rear rising surface 5b of the register case unit 5 as a fulcrum, and each second arm 28b of the pair of arm units 28 climbs over the edge of the second opening 20a of the recording paper storage unit 20. This places the printer cover 22 in the second release state.

[0078] In this second release state, the cover body 24 detaches to the rear of the printer unit 10. Therefore, even if the cover body 24 receives an external force in the opening direction and rotates further in the opening direction in the first release state, the printer cover 22 is not damaged, and the cover body 24 detaches to the rear of the printer unit 10, and the printer cover 22 is removed from the printer unit 10.

[0079] When attaching the printer cover 22 thus removed to the printer unit 10, first, with the cover body 24 in an upright position, the second arm 28b is inserted into the recording paper storage unit 20, and the pair of bearing parts 30 is positioned between each pair of guide ribs 34a in the pair of guide parts 34. In this state, the pair of bearing parts 30 are moved vertically while being guided by the pair of guide parts 34, so that the notches 32 provided in the pair of bearing parts 30 correspond to the pair of retaining shafts 29, respectively.

[0080] In this state, the pair of holding shafts 29 are inserted into the pair of cutouts 32, respectively, and pushed into the shaft holes 30a of the pair of bearing parts 30. This causes the pair of bearing parts 30 to be held by the pair of holding shafts 29. Therefore, even if the printer cover 22 is removed, it can be easily attached to the printer unit 10. At this time, the cover body 24 is positioned rearward of the rear of the second opening 20a of the recording paper storage unit 20, and is attached in an upright state to the printer unit 10 with the second opening 20a open.

[0081] Meanwhile, when information such as sales data is printed on recording paper 13 by printer unit 10 and this printed recording paper 13 is discharged from discharge port 14 to issue a receipt, drawer section 7 is pulled out from within drawer case 6 of the drawer device. At this time, front panel 7a of drawer section 7 is formed so as to tilt forward from the bottom surface of drawer case 6 in the direction in which drawer section 7 is pulled out when closing first opening 6a of drawer case 6.

[0082] That is, the front plate 7a of the drawer section 7 is inclined at a predetermined inclination angle θ3 so that its upper side protrudes forward and its lower side retracts, making it difficult to see from the operator's line of sight when pulling out the drawer section 7, thereby providing excellent security and preventing theft. In this case, both sides of the first opening 6a of the drawer case 6, i.e., the front ends of the pair of side plate portions 2b of the lower case 2, are also inclined at the same inclination angle θ3 as the front plate 7a of the drawer section 7, making them difficult to see from the operator's side, providing even better security and preventing theft.

[0083] Furthermore, when the drawer section 7 is pulled out from within the drawer case 6, the multiple money storage sections 36 within the drawer section 7 are exposed to the outside, allowing money to be handed over. In this case, the front inner surface of the coin storage section 36a arranged at the front side within the drawer section 7, among the money storage sections 36, is inclined at the same inclination angle θ3 as the front panel 7a of the drawer section 7, so that when coins are removed from the coin storage section 36a, the coins can be smoothly removed along the inclination of the inner surface of the coin storage section 36a.

[0084] Furthermore, the bills stored in bill storage section 36b arranged at the rear of drawer section 7 are held down by paper holder 36c, preventing the bills from accidentally scattering. In this case, because money storage section 36 is formed integrally with drawer section 7, the overall thickness of drawer section 7 can be made thinner than when multiple money storage sections 36 are provided separately from drawer section 7, thereby making drawer case 6 and device case 1 thinner overall.

[0085] Incidentally, in the device case 1 of this electronic cash register, the front and rear sides of the drawer case 6 formed by the case body 4 of the lower case 2 and the upper case 3 are formed parallel to each other while inclining forward, thereby improving the appearance and design of the device case 1.

[0086] In addition, the rear side of the upper surface of the case body 4 of this device case 1 is inclined upward toward the rear, and the register case section 5 is provided on this inclined upper surface. This also improves the appearance and design of the device case 1. In addition, the register case section 5 has a front rising surface 5a and a rear rising surface 5b formed parallel to each other while inclining toward the front side. This also improves the appearance and design of the device case 1.

[0087] In this case, the front-to-rear length of the register case part 5 of the equipment case 1 is short, approximately 2 / 3 of the front-to-rear length of the case main body part 4, and the register case part 5 is provided on the case main body part 4 except for its front side, so that a flat mounting surface 4a is provided on the case main body part 4 located in front of the register case part 5, and small items such as writing instruments can be easily placed on this mounting surface 4a.

[0088] In addition, the top surface of the register case section 5 of this equipment case 1 is inclined upward toward the rear, similar to the top surface of the rear side of the case main body section 4, which also improves the appearance and design, and makes it easier to see the various keys of the keyboard section 8 provided on the top surface of the register case section 5, improving key operability.

[0089] In this way, the printer cover 22, which is an opening / closing cover for this electronic register, comprises a cover body 24 which opens and closes the second opening 20a of the recording paper storage section 20 provided in the upper case 3, a rotational holding mechanism 25 which rotatably holds the cover body 24, and a release mechanism 26 which releases the holding of the cover body 24 by the rotational holding mechanism 25. The rotational holding mechanism 25 comprises a holding shaft 29 provided on the cover body 24 side, and a shaft hole 30a provided on the upper case 3 side into which the holding shaft 29 rotatably fits. The release mechanism 26 comprises a notch 32 provided on part of the outer periphery of the shaft hole 30a to allow the holding shaft 29 to be inserted and removed from the shaft hole 30a. The notch 32 is formed in a position which allows the holding shaft 29 to be removed from the shaft hole 30a when the cover body 24 is further rotated in the opening direction from the fully open state in which the second opening 20a is released. Therefore, even if the cover body 24 is rotated in the opening direction from the fully open state, damage to the printer cover 22 can be prevented.

[0090] In other words, in the printer cover 22 of this electronic register, when the cover body 24 is rotated further in the opening direction from the fully open state in which the second opening 20a is exposed, the retaining shaft 29 can be disengaged from the shaft hole 30a via the cutout portion 32 of the release mechanism 26, so that the release mechanism 26 can release the hold of the cover body 24 by the rotating holding mechanism 25, thereby preventing damage to the printer cover 22.

[0091] In this case, in the printer cover 22 of this electronic register, the rotating holding mechanism 25 has a holding shaft 29 provided in the upper case 3, and a bearing portion 30 having an axial hole 30a and a cutout portion 32 provided on an arm portion 28 inserted from the cover body 24 into the upper case 3, and the cutout portion 32 of the release mechanism 26 is formed so that the cutout width on the side closer to the axial hole 30a of the bearing portion 30 is smaller than the outer diameter of the holding shaft 29 and the cutout width on the side farther from the axial hole 30a of the bearing portion 30 is larger than the outer diameter of the holding shaft 29, thereby allowing the bearing portion 30 provided on the arm portion 28 to be held on the holding shaft 29 in the upper case 3, thereby enabling the cover body 24 to be supported reliably and satisfactorily, and the second opening 20a of the recording paper storage section 20 to be opened and closed satisfactorily by rotating the cover body 24 around the holding shaft 29.

[0092] In addition, in the printer cover 22 of this electronic register, the release mechanism 26 further includes a fulcrum abutment portion 31 provided on the arm portion 28 and abutting the edge of the second opening 20a of the recording paper storage section 20 in the fully open state with the second opening 20a open.Therefore, when the cover body 24 is rotated in the opening direction in the upright fully open state, the cover body 24 can be rotated smoothly using the principle of leverage, with the fulcrum abutment portion 31 of the arm portion 28 abutting the edge of the second opening 20a as the fulcrum.

[0093] As a result, in the printer cover 22 of this electronic register, when the cover body 24 is rotated in the opening direction in the upright, fully open state, the retaining shaft 29 can be disengaged from the shaft hole 30a of the bearing portion 30 through the cutout portion 32, so that the hold of the cover body 24 by the rotational holding mechanism 25 can be reliably and satisfactorily released by the release mechanism 26, thereby preventing damage to the printer cover 22 even if the printer cover 22 is rotated in the opening direction in the upright, fully open state.

[0094] In addition, the printer cover 22 of this electronic register is equipped with a cover body 24 which opens and closes the second opening 20a of the recording paper storage section 20 provided in the upper case 3, a rotational holding mechanism 25 which rotatably holds the cover body 24, a release mechanism 26 which releases the hold of the cover body 24 by the rotational holding mechanism 25 when the cover body 24 is rotated in the opening direction in the fully open state that opens the second opening 20a of the upper case 3, and a holding mechanism 27 which holds the cover body 24 in an upright position when the hold of the cover body 24 by the rotational holding mechanism 25 is released by the release mechanism 26, thereby preventing damage to the printer cover 22 and preventing the printer cover 22 from accidentally falling off the upper case 3.

[0095] In other words, in the printer cover 22 of this electronic register, when the cover body 24 is fully open with the second opening 20a of the upper case 3 exposed and rotates in the opening direction, and the retention of the cover body 24 by the rotating retention mechanism 25 is released by the release mechanism 26, the cover body 24 can be held in an upright position by the retention mechanism 27. Therefore, even if the retention of the cover body 24 by the rotating retention mechanism 25 is released, it is possible to reliably and effectively prevent the printer cover 22 from accidentally falling off the upper case 3.

[0096] In addition, in the printer cover 22 of this electronic register, when the hold of the cover body 24 by the rotating holding mechanism 25 is released by the release mechanism 26, the holding mechanism 27 holds the cover body 24 upright at two points: a first abutment contact P1 where the lower end 24a of the cover body 24 abuts against the outer surface of the upper case 3, and a second abutment contact P2 where the arm portion 28 abuts against the edge of the second opening 20a.Therefore, when the hold of the cover body 24 by the rotating holding mechanism 25 is released, the first abutment contact P1 and second abutment contact P2 of the holding mechanism 27 can reliably and satisfactorily hold the cover body 24 in an upright state.

[0097] As a result, the printer cover 22 of this electronic register can reliably and effectively prevent the cover body 24 from accidentally falling off the upper case 3, and since the cover body 24 is held in an upright position by the first abutment point P1 and the second abutment point P2 of the holding mechanism 27, the printer cover 22 can be easily removed from the upper case 3 by simply lifting the cover body 24, making it easy to handle the printer cover 22.

[0098] In addition, in the printer cover 22 of this electronic register, the arm portion 28 is provided with a first arm 28a extending from the inner surface of the cover body 24 when the second opening 20a is blocked, through the second opening 20a toward the inside of the recording paper storage section 20 of the upper case 3, and a second arm 28b extending from the inner end of the first arm 28a toward the retaining shaft 29 in the upper case 3.Therefore, even if the retaining shaft 29 is provided on the inner surface of the rear side inside the upper case 3, the first arm 28a and the second arm 28b can reliably and satisfactorily support the cover body 24 in a state in which it can be opened and closed, when the retaining shaft 29 is inserted into the shaft hole 30a of the bearing portion 30 to retain the bearing portion 30.

[0099] In this case, in the printer cover 22 of this electronic register, an axial hole 30a and a notch 32 of the bearing portion 30 are provided at the end of the second arm 28b corresponding to the holding shaft 29, so that even if the holding shaft 29 is provided on the inner surface of the rear side within the upper case 3, the holding shaft 29 can be inserted into the axial hole 30a of the bearing portion 30 through the notch 32, so that the bearing portion 30 can be easily and satisfactorily held to the holding shaft 29, and the holding shaft 29 can be easily and satisfactorily removed from the axial hole 30a of the bearing portion 30 through the notch 32.

[0100] Furthermore, in the printer cover 22 of this electronic register, the fulcrum abutment portion 31 is provided at the location of the second arm 28b located on the first arm 28a side, which eliminates the need to provide the fulcrum abutment portion 31 as a separate part, thereby simplifying the structure. Also, the location where the first arm 28a abuts against the edge of the second opening 20a is the second abutment point P2, which not only simplifies the structure but also allows the second abutment point P2 and the first abutment point P1 to reliably and satisfactorily hold the cover body 24 in an upright state.

[0101] In addition, in the printer cover 22 of this electronic register, the cover body 24 in the fully open state, which stands up by opening up the second opening 20a of the recording paper storage section 20 of the upper case 3, stands up behind the rear of the second opening 20a, so that the cover body 24 in the upright state does not get in the way.

[0102] In addition, in the printer cover 22 of this electronic register, the rear raised surface 5b located at the rear of the upper case 3 is inclined toward the front of the upper case 3, and the upright, fully open cover body 24 stands at a slight rearward incline relative to the vertical position relative to the upper case 3, thereby enabling the cover body 24 to stand in a stable state so that the upright, fully open cover body 24 does not inadvertently rotate in the closing direction.

[0103] In addition, in the printer cover 22 of this electronic register, a cut-out portion 33 is provided in the bearing portion 30 to facilitate elastic deformation of the retaining shaft 29 so as to push open the cut-out portion 32 and the axial hole 30a when the retaining shaft 29 is inserted through the cut-out portion 32. Therefore, when the retaining shaft 29 is inserted through the cut-out portion 32, the cut-out portion 33 facilitates elastic deformation so as to push open the notch width of the cut-out portion 32 and the inner diameter of the axial hole 30a. This allows the retaining shaft 29 to be reliably and satisfactorily removed from the axial hole 30a of the bearing portion 30, and also allows the retaining shaft 29 to be reliably and satisfactorily fitted into the axial hole 30a of the bearing portion 30.

[0104] In addition, the printer cover 22 of this electronic register is provided with a guide portion 34 that guides the bearing portion 30, which has an axial hole 30a and a cutout portion 32, and leads it to the holding shaft 29.This allows the guide portion 34 to guide the bearing portion 30 so that the cutout portion 32 of the bearing portion 30 corresponds to the holding shaft 29, so that the holding shaft 29 can be reliably and satisfactorily fitted into the axial hole 30a of the bearing portion 30 through the cutout portion 32.

[0105] In this case, the guide portion 34 has a pair of guide ribs 34a arranged in the vertical direction on the inner rear surface within the recording paper storage portion 20, and the retaining shaft 29 is provided between this pair of guide ribs 34a.With the bearing portion 30 positioned between the guide ribs 34a of the guide portion 34, the pair of bearing portions 30 can be guided and moved in the vertical direction to align the cutout portions 32 of the bearing portions 30 with the retaining shaft 29, and the retaining shaft 29 can be reliably and satisfactorily fitted into the shaft hole 30a of the bearing portion 30 through the cutout portions 32.

[0106] Furthermore, the printer cover 22 of this electronic register comprises a cover body 24 which closes the second opening 20a of the recording paper storage section 20 provided in the upper case 3 in an openable and closable manner, a rotational holding mechanism 25 which rotatably holds the cover body 24, and a release mechanism 26 which releases the hold of the cover body 24 by the rotational holding mechanism 25 when the cover body 24 in the fully open state with the second opening 20a open is rotated in the opening direction.The printer cover 22 has a first release state in which the cover body 24 is held in an upright position when the rotational hold by the rotational holding mechanism 25 is released by the release mechanism 26, and a second release state in which the cover body 24 detaches from the upper case 3 when it is further rotated in the opening direction in this first release state. This makes it possible to prevent damage to the printer cover 22 and to prevent the printer cover 22 from accidentally falling off the upper case 3.

[0107] That is, in the printer cover 22 of this electronic register, in the first released state, the cover body 24 is held upright at two points: a first abutment point P1 where the lower end 24a of the cover body 24 abuts against the rear rising surface 5b of the upper case 3, and a second abutment point P2 where the arm portion 28 provided on the cover body 24 abuts against the edge of the second opening 20a.By doing so, even if the rotational retention by the rotational retention mechanism 25 is released, the cover body 24 can be securely held in an upright state by the first abutment point P1 and the second abutment point P2.

[0108] As a result, with the printer cover 22 of this electronic register, when in the first release state, the cover body 24 can be reliably and effectively prevented from accidentally falling off the upper case 3, and since the cover body 24 is held in an upright position by the first abutment point P1 and the second abutment point P2 of the holding mechanism 27, the printer cover 22 can be easily removed from the upper case 3 by simply lifting the cover body 24, making it easy to handle the printer cover 22.

[0109] Furthermore, in the printer cover 22 of this electronic register, in the second release state in which the cover body 24 has been rotated further in the opening direction from the first release state, the cover body 24 rotates and detaches from the upper case 3, using the lower end portion 24a of the cover body 24 at the first abutment point P1 abutting against the rear raised surface 5b of the upper case 3 as a fulcrum. This allows the cover body 24 to be detached from the upper case 3 even if the cover body 24 rotates further in the opening direction in the first release state, thereby preventing damage to the printer cover 22.
