The large-diameter cylindrical shaft 20 is pushed down against this engagement force. Then, the guide protrusion 20 c is separated from the position restricting recess 23 b at the upper end portion and is disposed in the extendable guide groove 23 a of the storage cylinder portion 23.

  When the display case 14 is pushed down in this state, as shown in FIG. 8, the guide protrusion 20c of the large-diameter tube shaft 20 is inserted into the position restricting recess 23b located in the middle portion of the telescopic guide groove 23a of the storage tube portion 23. Once elastically engaged. For this reason, since the large-diameter cylindrical shaft 20 is not suddenly pushed into the storage cylinder portion 23, the large-diameter cylindrical shaft 20 can be safely pushed into the storage cylinder portion 23.

  Thereafter, as shown in FIG. 8, the guide protrusion 20c of the large-diameter cylinder shaft 20 moves further downward along the expansion / contraction guide groove 23a of the storage cylinder portion 23, and the large-diameter cylinder shaft 20 becomes the storage cylinder portion. When housed in 23, the guide protrusion 21a elastically engages with the position restricting recess 23b located at the lower end of the telescopic guide groove 23a. Thereby, as shown in FIG. 2, the display case 14 of the rotary display 4 is stored in the display storage unit 17 of the device main body 1.

  Thus, according to this electronic register, a plurality of support mechanisms 16 that support the rotation display 4 so as to be movable in the vertical direction with respect to the device main body 1 are provided along the vertical direction while supporting the rotation display 4. Since the support member 18 that expands and contracts in stages and the support attachment portion 19 that holds the support member 18 in the display storage portion 17 of the device body 1 so as to be able to appear and retract, the rotation indicator 4 can be formed large. The entire apparatus can be made compact without being affected by the length of the support member 18.

  That is, in this electronic register, the support member 18 can be contracted in a plurality of stages to shorten the entire length of the support member 18, so that the support member 18 can be stored compactly in the apparatus main body 1. Even if the length of the support member 18 when stored is shortened, the support member 18 can be elongated by extending it in a plurality of stages, so that the rotation indicator 4 can be reliably disposed above the device body 1. .

  Thereby, even if the rotation indicator 4 is formed large, the entire apparatus can be configured compactly without being affected by the length of the support member 18. In this case, in order to make the information displayed on the display panel 15 provided in the display case 14 of the rotary display 4 easy to see, the display panel 15 can be formed large and the display panel 15 can be enlarged. In order to increase the screen size of the display panel 15 as described above, even if the display case 14 is formed large, the overall length when the support member 18 is contracted can be shortened. The entire device can be configured compactly.

  In this case, the support member 18 has a different diameter, and a plurality of cylindrical shafts 20 and 21 are inserted into one of the support members 18 so that the other can protrude and retract. Since the cylinder restricting portion 22 that mutually restricts the position is provided, the support member 18 is inserted by inserting the small-diameter cylindrical shaft 21 into the large-diameter cylindrical shaft 20 among the multiple cylindrical shafts 20 and 21. The support member 18 can be lengthened by relatively pulling out the plurality of cylinder shafts 20 and 21, and even if the support member 18 is lengthened, the length of the support member 18 is ensured by the tube restricting portion 22. Can be maintained.

  The cylinder restricting portion 22 includes an expansion guide groove 20a provided on the inner peripheral surface of the large diameter cylinder shaft 20 among the plurality of cylinder shafts 20 and 21 along the axial direction, and the expansion guide groove 20a. A plurality of position restricting recesses 20b provided at predetermined intervals in the inside and provided on the outer peripheral surface of the small-diameter cylindrical shaft 21, and move in the telescopic guide groove 20a, and are elastically engaged with the plurality of position restricting recesses 20b. Since the guide projection 21a is detachably engaged, the support member 18 can be expanded and contracted reliably and satisfactorily, and when the support member 18 is stretched, the state of the support projection 18a is changed to the elasticity of the guide projection 21a. Can be maintained by force.

  That is, in this support member 18, the guide projections 21 a of the small-diameter cylindrical shaft 21 move in the telescopic guide groove 20 a of the large-diameter cylindrical shaft 20, so that the cylindrical shafts 20, 21 are relatively moved along the axial direction. Thus, the length of the support member 18 can be expanded and contracted. Further, when the support member 18 is expanded and contracted, the guide projection 21a of the small diameter cylindrical shaft 21 is elastically applied to any one of the plurality of position restricting recesses 20b provided in the expansion and contraction guide groove 20a of the large diameter cylindrical shaft 20. By engaging with each other, it is possible to elastically prevent the movement of the cylindrical shafts 20 and 21 in the axial direction, so that the expansion and contraction state of the support member 18 can be reliably and satisfactorily maintained.

  The support mounting portion 19 includes a storage tube portion 23 into which a large-diameter tube shaft 20 located at the outermost periphery among the plurality of tube shafts 20 and 21 of the support member 18 is inserted and retracted, and the storage tube portion 23. And a mounting restricting portion 24 for restricting the pulling position of the large-diameter cylindrical shaft 20 with respect to the support member 18 by pulling out the large-diameter cylindrical shaft 20 of the supporting member 18 from the storage cylindrical portion 23. The length can be increased, and even if the support member 18 is lengthened, the length can be reliably and satisfactorily maintained by the attachment restricting portion 24.

  That is, in the support mounting portion 19, when the support member 18 is stretched and the rotation indicator 4 is disposed above the apparatus main body 1, the large-diameter cylindrical shaft 20 of the support member 18 is pulled out from the storage cylinder portion 23. Thereby, the support member 18 of the part exposed outside can be further lengthened. In addition, when the large-diameter cylinder shaft 20 of the support member 18 is pulled out from the storage cylinder portion 23 in order to arrange the rotation indicator 4 above the device body 1, the attachment restriction portion 24 causes the large-diameter cylinder. The large-diameter cylindrical shaft 20 can be reliably held so that the shaft 20 is not pushed into the storage cylindrical portion 23.

  Further, the support mounting portion 19 regulates the position of the large-diameter cylindrical shaft 20 of the support member 18 with respect to the storage cylinder portion 23 when the rotary indicator 4 is stored in the display storage portion 17 of the device body 1. By releasing the position restriction by the mounting restriction part 24, the large-diameter cylindrical shaft 20 can be easily pushed into the storage cylinder part 23, and the support member 18 can be stored in the storage cylinder part 23. Thus, the portion of the support member 18 exposed to the outside can be shortened, so that the rotary indicator 4 can be stored compactly and satisfactorily in the display storage portion 17 of the device main body 1.

  In this case, the rotation indicator 4 is provided with the display panel 15 on the side surface of the display case 14, and the bottom of the display case 14 rotates to the upper portion of the small-diameter cylindrical shaft 21 positioned at the uppermost position when the support member 18 is extended. When the support member 18 is extended, the small-diameter cylindrical shaft 21 extends to the highest position, and the extended small-diameter cylindrical shaft 21 supports the display case 14 above the device main body 1. In addition, the display case 14 can be satisfactorily rotated in a state where the bottom of the display case 14 is disposed above the device main body 1, so that the display panel 15 provided on the display case 14 can be displayed by the customer. It can be oriented in an easy-to-see direction.

  Further, the device main body 1 is provided with a display storage portion 17 for storing the rotary indicator 4 so as to be able to appear and retract, and a support attachment for storing the support member 18 in a contracted state at the bottom of the display storage portion 17. By providing the portion 19, the support member 18 can be contracted and stored in the support mounting portion 19, and the rotary indicator 4 can be compactly and satisfactorily stored in the display storage portion 17 of the device body 1. Thus, the rotation indicator 4 can be well protected and the entire device can be made compact.

  In the first embodiment described above, the tube restricting portion 22 in the support member 18 of the support mechanism 16 is provided with the expansion / contraction guide groove 20a and the position restricting recess 20b on the inner peripheral surface of the large diameter tube shaft 20, and the small diameter Although the case where the guide protrusion 21a is provided on the outer peripheral surface of the cylindrical shaft 21 has been described, the present invention is not limited to this. The structure which provided the guide protrusion in the inner peripheral surface of the cylindrical shaft 20 of this may be sufficient. Even if comprised in this way, there exists an effect similar to Embodiment 1 mentioned above.

That is, the guide projection 36a is formed in a tongue-like shape having elasticity by providing a cut in the insertion cylinder 36, and protrudes from the inner peripheral surface of the insertion cylinder 36 so that the protruding portion can extend and retract. It moves in 34a, and it is comprised so that it may engage in a plurality of position control recessed parts 34b elastically so that engagement / disengagement is possible.

  Thereby, as shown in FIG. 13 and FIG. 14, the tube restricting portion 35 has the guide protrusion 36 a provided on the inner peripheral surface of the insertion tube 36 in the first tubular portion 33, and the second protrusion opposite to the guide protrusion 36 a.

In this case, when the guide protrusion 36a engages with the position restricting recess 34b located at the upper end portion in the telescopic guide groove 34a, the second cylindrical portion 34 is placed most into the insertion hole 36 of the first cylindrical portion 33. The position is restricted in the inserted state.

  Further, as shown in FIGS. 13 and 14, when the guide protrusion 36a engages with the position restricting recess 34b located at the intermediate portion in the telescopic guide groove 34a, the second tubular portion 34 is moved to the first tube. The position is regulated in a state where approximately half is inserted into the insertion hole 36 of the shaped portion 33. Further, when the guide protrusion 36a engages with the position restricting recess 34b located at the lower end portion in the expansion / contraction guide groove 34a, the second cylindrical portion 34 is moved the most from the insertion hole 36 of the first cylindrical portion 33. The position is regulated in the protruding state.

  On the other hand, as shown in FIG. 12, the support mounting portion 32 includes a storage cylinder portion 37 into which the first cylindrical portion 33 of the support member 31 is inserted and retracted, and a first cylindrical portion with respect to the storage cylinder portion 37. And an attachment restricting portion 38 that restricts the pull-out position of 33. The storage cylinder portion 37 is formed in a rectangular frame shape.

  As shown in FIGS. 11 and 12, the storage cylinder portion 37 has a vertical length in the first cylindrical portion 33 of the first and second cylindrical portions 33, 34. It is formed shorter than the length (height). The storage cylinder portion 37 is configured such that the lower portion is inserted into the device main body 1 and the upper portion is attached to the bottom portion of the display storage portion 17 provided on the back surface of the device main body 1.

  Further, as shown in FIG. 12, the attachment restricting portion 38 restricts the relative lifting position when the first tubular portion 33 of the support member 31 is lifted upward from the storage tubular portion 37. A pair of expansion / contraction guide grooves 33a provided on the outer surface of the first cylindrical portion 33, position restriction hook portions 33b provided at predetermined locations on the outer surface of the first cylindrical portion 33, and And a pair of guide protrusions 37 a provided on the inner surface of the opposing storage cylinder portion 37.

  In this case, as shown in FIG. 12, the pair of extendable guide grooves 33 a is provided on the outer surface of the first cylindrical portion 33 along the axial direction (vertical direction). The position restricting hook portion 33b is provided on the outer surface of the first cylindrical portion 33 at a location corresponding to the upper end portions of the pair of telescopic guide grooves 33a, and elastically removably engages the upper end portion of the storage cylinder portion 37. It is configured to lock.

  That is, as shown in FIG. 12, the position restricting hook portion 33 b is formed into a tongue-like shape having elasticity by providing a cut in the first tubular portion 33, and the position of the first tubular portion 33. It protrudes from the outer surface so that it can protrude and retract, and the protruding portion is configured to elastically engage and disengage the upper end portion of the storage cylinder portion 37.

  As shown in FIG. 12, the pair of guide protrusions 37a are provided so as to protrude from the inner surface of the storage cylinder portion 37, and are configured to be movably inserted into the pair of extendable guide grooves 33a. That is, the pair of guide protrusions 37a is formed in a tongue-like shape having elasticity by providing a cut in the storage cylinder portion 37, and protrudes from the inner surface of the storage cylinder portion 37 so that the protruding portions are a pair. It is configured to move elastically in the telescopic guide groove 33a.

  Thereby, as shown in FIG. 12, in the attachment restricting portion 38, a pair of guide projections 37a provided on the inner surface of the storage cylinder portion 37 is provided on the outer surface of the first cylindrical portion 33 opposed thereto. The first cylindrical portion 33 is configured to move in the axial direction (vertical direction) with respect to the storage cylindrical portion 37 by moving in the vertical direction within the pair of extendable guide grooves 33a.

  In addition, as shown in FIG. 12, the attachment restricting portion 38 is provided with a pair of guide projections 37a provided on the inner surface of the storage cylinder portion 37 on the outer surface of the first cylindrical portion 33 opposed thereto. When reaching the upper part of the pair of telescopic guide grooves 33a, the position restricting hook part 33b provided on the outer surface of the first cylindrical part 33 elastically locks the upper end part of the storage cylinder part 37, The first cylindrical portion 33 is configured to elastically prevent expansion and contraction movement in the axial direction.

Next, the operation of the rotation indicator 4 in such an electronic register will be described.
In order to make it easier for the customer to see the information displayed on the display panel 15 of the rotation display 4, the rotation display 4 is pulled up above the display storage portion 17 of the device body 1 and the customer is displayed on the display panel 15. What is necessary is just to rotate the display case 14 in the direction which is easy to see information. That is, when the rotary indicator 4 is pulled up, the support member 31 of the support mechanism 30 extends along the axial direction, and the support member 31 is pulled up from the support mounting portion 32.

  At this time, as shown in FIG. 14A, guide protrusions 36 a provided on the inner peripheral surface of the insertion cylinder 36 in the first cylindrical portion 33 are provided on the outer peripheral surface of the second cylindrical portion 34. Since the upper and lower guide grooves 34a are engaged with the position restricting recess 34b at the upper end, the second cylindrical portion 34 is pulled out from the insertion tube 36 against this engaging force. Then, the guide protrusion 36a provided on the inner peripheral surface of the insertion tube 36 moves along the oblique vertical direction that is the axial direction thereof in the expansion / contraction guide groove 34a provided on the outer peripheral surface of the second cylindrical portion 34. The support member 31 extends obliquely upward.

  Further, at this time, as shown in FIG. 12, the pair of guide protrusions 37 a provided on the inner peripheral surface of the storage cylinder portion 37 are provided on the outer peripheral surface of the first cylindrical portion 33 in the support member 31. The first cylindrical portion 33 is lifted upward along the axial direction (vertical direction) from the inside of the storage cylinder portion 37.

  When the guide protrusion 36a provided on the inner peripheral surface of the insertion tube 36 in the first tubular portion 33 moves relatively to the upper side of the expansion / contraction guide groove 34a in the second tubular portion 34, As shown in FIGS. 13 and 14 (a), the guide protrusion 36a is temporarily elastically engaged with the position restricting recess 34b located at the intermediate portion in the telescopic guide groove 34a. For this reason, the second tubular portion 34 is not suddenly pulled out from the insertion tube 36 of the first tubular portion 33.

  Thereafter, as shown in FIG. 13 and FIG. 14B, the guide protrusion 36 a in the insertion tube 36 in the first tubular portion 33 is the lower end portion in the extendable guide groove 34 a in the second tubular portion 34. It engages in the position restricting recess 34b located at the position so as to be detachably and elastically engaged. Thereby, the movement of the second cylindrical portion 34 in the up-down direction, which is the axial direction, with respect to the first cylindrical portion 33 is elastically prevented, and the second cylindrical portion 34 becomes the first cylindrical portion 33. Is pulled out most from the inside of the insertion cylinder 36.

  Further, when the pair of guide projections 37a of the storage cylinder portion 37 relatively move in the pair of expansion guide grooves 33a of the first cylindrical portion 33 and move to the upper portions of the pair of expansion guide grooves 33a. As shown in FIG. 12, the position restricting hook portion 33 b provided on the outer surface of the first tubular portion 33 elastically locks the upper end portion of the storage tubular portion 37. Thereby, the movement in the axial direction (vertical direction) of the first tubular portion 33 relative to the storage tubular portion 37 is elastically prevented.

  As described above, when the support member 31 of the support mechanism 30 is extended upward in a plurality of stages, and when the first cylindrical portion 33 of the support member 31 is pulled out from the storage cylinder portion 37 of the support mounting portion 32, As shown in FIG. 11, the rotation indicator 4 is disposed above the device main body 1. At this time, the rotation indicator 4 is separated from the device main body 1. For this reason, it is possible to prevent the input display unit 2 and the printer cover 10 of the printer unit 3 from interfering with the rotary display 4.

  That is, as shown in FIG. 11, when the unit case 5 of the input display unit 2 is rotationally moved to stand up rearward, the unit case 5 does not come into contact with the rotary indicator 4. Further, when the printer cover 10 of the printer unit 3 is opened and closed, the printer cover 10 does not come into contact with the rotation display 4.

  In this state, the display case 14 of the rotary display 4 can be rotated so that the display panel 15 provided on the display case 14 can be oriented in an easy-to-view direction for the customer. In other words, the rotation indicator 4 is attached to the upper portion of the second cylindrical portion 34 that is positioned at the uppermost position of the support member 31 in a state in which the rotation of the display case 14 is rotatable in the horizontal direction. The display case 14 can be rotated around the second cylindrical portion 34 so that the display panel 15 can be oriented in a direction that is easy for the customer to see.

  On the other hand, when the rotary indicator 4 is accommodated in the display accommodating portion 17 of the device main body 1, with respect to the position restricting recess 34b located at the lower end of the telescopic guide groove 34a in the second cylindrical portion 34, Since the guide protrusion 36a of the insertion tube 36 in the first tubular portion 33 is elastically engaged, the display case 14 is pushed down together with the second tubular portion 34 against this engagement force. Then, the guide protrusion 36a of the insertion tube 36 is detached from the position restricting recess 34b located at the lower end portion of the expansion / contraction guide groove 34a and inserted into the expansion / contraction guide groove 34a.

  In this state, when the display case 14 is further pushed down, the guide protrusion 36a is once elastically engaged with the position restricting recess 34b located at the intermediate portion in the telescopic guide groove 34a. For this reason, since the 2nd cylindrical part 34 is not pushed suddenly in the insertion cylinder 36 of the 1st cylindrical part 33, the 2nd cylindrical part 34 is safely 1st cylindrical part 33. Can be pushed into the insertion cylinder 36.

  After that, as shown in FIG. 14A, when the second cylindrical portion 34 is further pushed into the insertion tube 36 of the first cylindrical portion 33, the guide protrusion 36a becomes the upper end portion of the telescopic guide groove 34a. The second cylindrical portion 34 is accommodated in the insertion cylinder 36 in the first cylindrical portion 33 by elastically engaging with the position restricting concave portion 34 b located at the position.

  Further, since the position restricting hook portion 33b of the first cylindrical portion 33 is elastically locked to the upper end portion of the storage cylindrical portion 37 in the support mounting portion 32, this resistance is resisted. The display case 14 is pushed down together with the first cylindrical portion 33. Then, the locking by the position restriction hook portion 33 b of the first cylindrical portion 33 with respect to the upper end portion of the storage cylinder portion 37 is released.

  When the display case 14 is further pushed down in this state, the pair of guide projections 37a provided on the inner surface of the storage cylinder portion 37 is relatively moved along the pair of expansion / contraction guide grooves 33a provided on the outer surface of the first cylindrical portion 33. Therefore, the first cylindrical portion 33 is stored in the storage cylindrical portion 37. Thereby, the display case 14 of the rotation indicator 4 is accommodated in the display accommodating portion 17 of the device main body 1.

  As described above, in this electronic register as well as in the first embodiment, the support mechanism 30 that supports the rotation display 4 so as to be movable in the vertical direction with respect to the device main body 1 supports the rotation display 4 in the vertical direction. Since the support member 31 that expands and contracts in a plurality of stages along the direction and the support attachment portion 32 that holds the support member 31 in the display storage portion 17 of the device main body 1 so as to be able to appear and retract, the rotation indicator 4 is provided. Even if it is formed large, the entire apparatus can be made compact without being affected by the length of the support member 31.

  That is, in this electronic register, the length of the support member 31 can be shortened by contracting the support member 31 in a plurality of stages, so that the support member 31 can be stored compactly with respect to the apparatus body 1. Even if the length of the support member 31 when stored is shortened, the support member 31 can be extended and lengthened in a plurality of stages, so that the rotary indicator 4 can be reliably disposed above the device main body 1.

  Thereby, even if the rotation indicator 4 is formed large, the entire apparatus can be configured compactly without being affected by the length of the support member 31. Also in this case, in order to make the information displayed on the display panel 15 of the rotary display 4 easy to see, the display panel 15 can be formed large and the display panel 15 can be enlarged. 15, even if the display case 14 is formed large, the length of the support member 31 when contracted can be shortened. Therefore, it is not necessary to form the device main body 1 large, and the entire device It can be configured compactly.

  In this case, the support mechanism 30 is configured to expand and contract in a plurality of stages in the diagonally up and down direction with the support member 31 supporting the rotation indicator 4, so that when the support member 31 is stretched, Since the rotation display 4 can be extended obliquely upward, the rotation display 4 can be sufficiently separated from the device main body 1 when the rotation display 4 is moved above the device main body 1. Can be arranged so as not to interfere with the unit case 5 of the input display unit 2 and the printer cover 10 of the printer unit 3.

  That is, in the support mechanism 30, the support member 31 includes first and second cylindrical portions 33 and 34, and the insertion cylinder 36 is inclined in the front-rear direction of the device main body 1 in the first cylindrical portion 33. Thus, since the second cylindrical portion 34 is inserted into the insertion tube 36 in the first cylindrical portion 33 so as to be able to protrude and retract, the second cylindrical portion 34 is provided in the first cylindrical portion 33. When the first cylindrical portion 33 is pulled out from the insertion tube 36, the second cylindrical portion 34 can be pulled out obliquely upward. For this reason, when the rotation indicator 4 is moved above the device main body 1, the rotation indicator 4 can be reliably separated from the device main body 1.

(Embodiment 3)
Next, a third embodiment in which the present invention is applied to an electronic register will be described with reference to FIGS. Also in this case, the same parts as those in the first embodiment shown in FIGS.
As shown in FIGS. 15 and 16, the electronic register has a configuration that is different from that of the first embodiment in the support mechanism 40 that supports the rotation indicator 4, and has substantially the same configuration as that of the first embodiment.

Next, the operation of the rotation indicator 4 in such an electronic register will be described.
In order to make it easier for the customer to see the information displayed on the display panel 15 of the rotation display 4, the rotation display 4 is pulled up above the display storage portion 17 of the device body 1 and the customer is displayed on the display panel 15. What is necessary is just to rotate the display case 14 in the direction which is easy to see information. That is, when the rotary indicator 4 is pulled up, the support member 41 of the support mechanism 40 extends along the axial direction, and the support member 41 is pulled up from the support mounting portion 42.

  At this time, as shown in FIG. 17, the guide protrusion 46 a provided on the inner peripheral surface of the insertion tube 46 in the first cylindrical portion 43 is provided with an extendable guide provided on the outer peripheral surface of the second cylindrical portion 44. Since it engages with the position restricting recess 44b at the upper end in the groove 44a, the second tubular portion 44 is pulled out from the insertion tube 46 against this engaging force. Then, the guide protrusion 46a provided on the inner peripheral surface of the insertion cylinder 46 moves along the vertical direction in the extendable guide groove 44a provided on the outer peripheral surface of the second cylindrical portion 44, and the support member 41 is moved. It extends upward.

  Further, at this time, as shown in FIG. 17, the pair of guide protrusions 47 a provided on the inner peripheral surface of the storage cylinder portion 47 are paired with the pair of extendable guide grooves provided on the outer peripheral surface of the first cylindrical portion 43. Since it engages with the position restricting recess 43 b at the upper end in 43 a, the first tubular portion 43 is pulled out from the storage tubular portion 47 against this engagement force. Then, the pair of guide protrusions 47a provided on the inner peripheral surface of the storage cylinder portion 47 are relatively inclined upward in the pair of extension guide grooves 43a provided on the outer peripheral surface of the first cylindrical portion 43. The first tubular portion 43 is pulled up obliquely upward from the storage tubular portion 47.

  Then, as shown in FIG. 18, the guide protrusion 46a in the insertion tube 46 in the first cylindrical portion 43 moves in the expansion / contraction guide groove 44a in the second cylindrical portion 44, and the expansion / contraction guide groove 44a. When the lower end portion of the guide tube 46 is reached, the guide protrusion 46a in the insertion tube 46 is elastically engaged in a position restricting recess 44b located at the lower end portion in the telescopic guide groove 44a of the second tubular portion 44 so as to be detachable. Match. Thereby, the movement of the second cylindrical portion 44 in the up-down direction, which is the axial direction of the second cylindrical portion 44 with respect to the first cylindrical portion 43, is elastically prevented, so that the second cylindrical portion 44 is moved to the first cylindrical portion 43. Is pulled out most from the insertion tube 46 in

  Further, when the pair of guide projections 47a of the storage cylinder portion 47 move relatively in the pair of extension guide grooves 43a in the first cylindrical portion 43 and move to the lower portions of the pair of extension guide grooves 43a. As shown in FIG. 18, the pair of guide protrusions 47a are elastically engaged with each other in a position restricting recess 43b located at the lower end in the pair of telescopic guide grooves 43a. Thereby, the movement of the first cylindrical portion 43 in the diagonally up and down direction with respect to the storage cylindrical portion 47 is elastically prevented.

  As described above, when the support member 41 of the support mechanism 40 is extended upward in a plurality of stages, and the first cylindrical portion 43 of the support member 41 is pulled obliquely upward from the inside of the storage cylinder portion 47 of the support mounting portion 42. As shown in FIG. 18, the rotation indicator 4 is disposed above the device main body 1. At this time, the rotation indicator 4 moves away from the device main body 1 to the right side. For this reason, it is possible to prevent the input display unit 2 and the printer cover 10 of the printer unit 3 from interfering with each other with respect to the rotary display 4.

  That is, as shown in FIG. 18, when the unit case 5 of the input display unit 2 is rotationally moved to stand up rearward, the unit case 5 does not come into contact with the rotary indicator 4. Further, when the printer cover 10 of the printer unit 3 is opened and closed, the printer cover 10 does not come into contact with the rotation display 4.

  In this state, the display case 14 of the rotary display 4 can be rotated so that the display panel 15 provided on the display case 14 can be oriented in an easy-to-view direction for the customer. That is, the rotation indicator 4 is attached to the upper portion of the second cylindrical portion 44 positioned at the uppermost position of the support member 41 so that the bottom portion of the display case 14 is horizontally rotatable. The display case 14 can be rotated around the second cylindrical portion 44 so that the display panel 15 can be oriented in an easy-to-view direction for the customer.

  On the other hand, when the rotary indicator 4 is accommodated in the display accommodating portion 17 of the device main body 1, the position restricting recess 44 b located at the lower end of the extendable guide groove 44 a in the second cylindrical portion 44 is Since the guide protrusion 46 a of the insertion tube 46 in the first tubular portion 43 is elastically engaged, the display case 14 is pushed down together with the second tubular portion 44 against this engagement force. Then, the guide protrusion 46a of the insertion tube 46 is detached from the position restricting recess 44b located at the lower end portion of the expansion / contraction guide groove 44a and moves in the expansion / contraction guide groove 44a.

  When the display case 14 is further pushed down in this state, as shown in FIG. 17, the guide protrusion 46 a of the insertion tube 46 relatively moves in the telescopic guide groove 44 a of the second cylindrical portion 44, and the second The cylindrical part 44 is pushed into the insertion cylinder 46 of the first cylindrical part 43. Then, the guide protrusion 46 a elastically engages with the position restricting recess 44 b located at the upper end of the telescopic guide groove 44 a, whereby the second cylindrical portion 44 is inserted into the insertion cylinder 46 in the first cylindrical portion 43. It is stored in.

  At this time, the pair of guide protrusions 47 a of the storage cylinder 47 in the support mounting portion 42 is elastic to each position restriction recess 43 b located at the lower end in the pair of extendable guide grooves 43 a in the first cylinder 43. Therefore, the display case 14 is pushed down together with the first cylindrical portion 43 against this engagement force. Then, the pair of guide protrusions 47a located at the upper end of the storage cylinder 47 is separated from the position restricting recesses 43b of the first cylinder 43 and pulled out into the pair of extendable guide grooves 43a.

  In this state, when the display case 14 is further pushed down, a pair of guide protrusions 47a provided on the inner surface of the storage cylinder portion 47 is provided with a pair of guide protrusions 47a provided on the outer surface of the first cylindrical portion 43 as shown in FIG. The first cylindrical portion 43 is stored in the storage cylinder portion 47 because it moves relatively obliquely downward along the extendable guide groove 43a. Thereby, the display case 14 of the rotation indicator 4 is accommodated in the display accommodating portion 17 of the device main body 1.

  As described above, in this electronic register as well as in the first embodiment, the support mechanism 40 that supports the rotation display 4 so as to be movable in the vertical direction with respect to the device main body 1 supports the rotation display 4 in the vertical direction. Since the support member 41 that expands and contracts in a plurality of steps along the direction and the support attachment portion 42 that holds the support member 41 in the display storage portion 17 of the device main body 1 so as to be able to appear and retract, the rotation indicator 4 is provided. Even if formed large, the entire apparatus can be made compact without being affected by the length of the support member 41.

  That is, in this electronic register, the length of the support member 41 can be shortened by contracting the support member 41 in a plurality of stages, so that the support member 41 can be stored compactly with respect to the device main body 1. Even if the length of the support member 41 during storage is shortened, the support member 41 can be elongated by extending it in a plurality of stages, so that the rotary indicator 4 can be reliably disposed above the device main body 1.

  Thereby, even if the rotation indicator 4 is formed large, the entire apparatus can be configured compactly without being affected by the length of the support member 41. Also in this case, in order to make the information displayed on the display panel 15 of the rotary display 4 easy to see, the display panel 15 can be formed large and the display panel 15 can be enlarged. 15, even if the display case 14 is formed larger, the length of the support member 41 when it is contracted can be shortened. It can be configured compactly.

  In this case, the support mechanism 40 expands and contracts in a plurality of stages in the vertical direction with the support member 41 supporting the rotation indicator 4, and the support mounting portion 42 protrudes and appears in the vertical direction of the support member 41. Since the support member 41 is stretched and pulled out from the support mounting portion 42 by being configured to be able to be held, it can be lifted obliquely upward, so that the rotary indicator 4 is positioned above the device body 1. When moved, the rotation indicator 4 can be sufficiently separated from the device main body 1, so that the rotation indicator 4 does not interfere with the unit case 5 of the input display unit 2 or the printer cover 10 of the printer unit 3. Can be arranged as follows.

  That is, in the support mechanism 40, the support member 41 includes first and second cylindrical portions 43 and 44, and the second cylindrical portion is inserted in the insertion tube 46 provided in the first cylindrical portion 43. 44 is inserted in a retractable manner, and the first cylindrical portion 43 can be protruded and retracted in an obliquely vertical direction in a state where the first cylindrical portion 43 is inclined in the horizontal direction of the device main body 1 in the storage cylindrical portion 47 of the support mounting portion 42. Because of the inserted configuration, when the first cylindrical portion 43 is pulled out from the storage cylindrical portion 47 of the support mounting portion 42, the first cylindrical portion 43 can be pulled out obliquely upward. For this reason, when the rotation indicator 4 is moved above the device main body 1, the rotation indicator 4 can be reliably separated from the device main body 1.

  That is, as shown in FIGS. 19 to 21, the pair of guide protrusions 57 a are formed in a tongue-like shape having elasticity by providing cuts in the storage cylinder portion 57, and are projected and retracted from the inner surface of the storage cylinder portion 57. The protruding portions are configured to be elastically movable in the pair of extension guide grooves 53d and to be removably engaged with the plurality of position restricting recesses 53b. Further, the position restricting hook portion 53f is formed on the outer peripheral surface of the first cylindrical portion 53 so as to protrude in the shape of a tongue piece having elasticity, and the protruding portion is elastic so that the upper end portion of the storage cylinder portion 57 can be engaged and disengaged. It is comprised so that it may latch.

  Accordingly, as shown in FIGS. 19 to 21, the attachment restricting portion 58 has a pair of guide protrusions 57 a provided on the inner surface of the storage cylinder portion 57 on the outer surface of the first cylindrical portion 53 facing this. The first cylindrical portion 53 is configured to move in the vertical direction with respect to the storage cylindrical portion 57 by moving in the vertical direction within the pair of provided extension / contraction guide grooves 53d.

  In addition, as shown in FIGS. 19 to 21, the attachment restricting portion 58 has a pair of guide projections 57 a provided on the inner surface of the storage cylinder portion 57 on the outer surface of the first cylindrical portion 53 facing this. When the upper and lower end portions of the provided pair of extendable guide grooves 53d are reached, the position restricting recesses 53e provided at the upper and lower ends of the pair of extendable guide grooves 53d are elastically engaged, thereby One cylindrical portion 53 is configured to elastically prevent vertical movement in the vertical direction.

Next, the operation of the rotation indicator 4 in such an electronic register will be described.
In order to make it easier for the customer to see the information displayed on the display panel 15 of the rotation display 4, the rotation display 4 is pulled up above the display storage portion 17 of the device body 1 and the customer is displayed on the display panel 15. What is necessary is just to rotate the display case 14 in the direction which is easy to see information. That is, when the rotary indicator 4 is pulled up, the support member 51 of the support mechanism 50 extends along the axial direction, and the support member 51 is pulled up from the support mounting portion 52.

  At this time, as shown in FIGS. 19 to 21, the guide protrusion 54 a provided on the outer peripheral surface of the second cylindrical portion 54 is provided with an extendable guide groove provided on the inner peripheral surface of the first cylindrical portion 53. The second cylindrical portion 54 is pulled out from the first cylindrical portion 53 against the engaging force because it is engaged with the position restricting concave portion 53b of the upper end portion in 53a. Then, the guide protrusion 54a provided on the outer peripheral surface of the second cylindrical portion 54 moves along the vertical direction in the expansion / contraction guide groove 53a provided on the inner peripheral surface of the first cylindrical portion 53, The support member 51 extends upward.

  Further, at this time, as shown in FIGS. 19 to 21, the pair of guide protrusions 57 a provided on the inner peripheral surface of the storage cylinder portion 57 are paired with the pair of guide protrusions 57 a provided on the outer peripheral surface of the first cylindrical portion 53. Since the upper end portion of the telescopic guide groove 53d is engaged with the position restricting recessed portion 53e, the first tubular portion 53 is pulled out from the storage tubular portion 57 against this engaging force. Then, the pair of guide protrusions 57a provided on the inner peripheral surface of the storage cylinder portion 57 are relatively directed upward in the pair of extendable guide grooves 53d provided on the outer peripheral surface of the first cylindrical portion 53. The first cylindrical portion 53 is moved upward from the inside of the storage cylinder portion 57.

  Then, as shown in FIGS. 19 to 21, the guide projection 54a of the second cylindrical portion 54 moves in the expansion / contraction guide groove 53a in the first cylindrical portion 53, and the upper end of the expansion / contraction guide groove 53a. When reaching the portion, the guide protrusion 54 a of the second tubular portion 54 corresponds to the position restricting guide groove 53 b located at the upper end portion in the extendable guide groove 53 a of the first tubular portion 53. In this state, when the rotation indicator 4 is rotated in the horizontal direction, the second cylindrical portion 54 rotates with the rotation.

  At this time, the guide protrusion 54 a of the second tubular portion 54 is inserted into the position restricting guide groove 53 b that is continuous with the extendable guide groove 53 a of the first tubular portion 53. As a result, the rotary indicator 4 rotates together with the second cylindrical portion 54, but the movement of the second cylindrical portion 54 in the vertical direction, which is the axial direction of the second cylindrical portion 53, is prevented, and The second cylindrical portion 54 is maintained in the state where it is most pulled out from the first cylindrical portion 53.

  Further, when the pair of guide protrusions 57a of the storage cylinder portion 57 relatively move in the pair of extension guide grooves 53d of the first cylindrical portion 53 and move to the upper portions of the pair of extension guide grooves 53d. The pair of guide protrusions 57a are elastically engaged with each other in a position restricting recess 53e located at the upper end in the pair of extendable guide grooves 53d. At this time, the position restriction hook portion 53 f of the first tubular portion 53 elastically locks the upper end portion of the storage tubular portion 57. Thereby, the vertical movement of the first tubular portion 53 relative to the storage tubular portion 57 is elastically prevented.

  As described above, when the support member 51 of the support mechanism 50 is extended upward in a plurality of stages, and when the first cylindrical portion 53 of the support member 51 is pulled out from the storage cylinder portion 57 of the support mounting portion 52, As shown in FIGS. 20 and 21, the rotation indicator 4 is disposed above the device main body 1. In this state, the display case 14 of the rotary display 4 can be rotated so that the display panel 15 provided on the display case 14 can be oriented in an easy-to-view direction for the customer.

  That is, as shown in FIGS. 19 to 21, the rotary indicator 4 is provided integrally with the bottom portion of the display case 14 on the upper portion of the second cylindrical portion 54 positioned on the uppermost side of the support member 51. Accordingly, the display case 14 can be rotated around the second cylindrical portion 54 together with the second cylindrical portion 54 so that the display panel 15 can be oriented in an easy-to-view direction for the customer.

  On the other hand, when the rotary indicator 4 is stored in the display storage part 17 of the device main body 1, the rotary indicator 4 is rotated so that the guide projection 54a of the second cylindrical part 54 is moved to the first cylindrical part. By rotating and moving along the position restricting guide groove 53b provided on the inner peripheral surface of 53, the guide protrusion 54a is made to correspond to the extendable guide groove 53a. In this state, the display case 14 is pushed down together with the second cylindrical portion 54. Then, the guide protrusion 54 a of the second tubular portion 54 is inserted into the extendable guide groove 53 a of the first tubular portion 53.

  When the display case 14 is further pushed down, the guide protrusion 54a of the second cylindrical portion 54 relatively moves in the expansion / contraction guide groove 53a of the first cylindrical portion 53, and the second cylindrical portion 54 is moved. Is pushed into the first cylindrical portion 53. Then, the lower limit stopper portion 54c of the second cylindrical portion 54 abuts on a step portion (not shown) provided on the inner peripheral surface of the first cylindrical portion 53 and the lower limit position is regulated, The second tubular portion 54 is accommodated in the first tubular portion 53.

  At this time, the locking of the position restricting hook portion 53f of the first tubular portion 53 with respect to the upper end portion of the storage tubular portion 57 is released. The pair of guide protrusions 57 a of the storage cylinder portion 57 in the support mounting portion 52 are elastically engaged with the respective position restriction recesses 53 e located at the upper end portions in the pair of extendable guide grooves 53 d in the first cylindrical portion 53. Therefore, the display case 14 is pushed down together with the first cylindrical portion 53 against this engagement force. Then, the pair of guide protrusions 57a of the storage cylinder portion 57 are separated from the position restricting recesses 53e of the first cylindrical portion 53 and move in the pair of extendable guide grooves 53d.

  In this state, when the display case 14 is further pushed down, the pair of guide protrusions 57a provided on the inner surface of the storage cylinder portion 57 extends along the pair of extendable guide grooves 53d provided on the outer surface of the first cylindrical portion 53. Since it moves relatively downward, the first cylindrical portion 53 is stored in the storage cylindrical portion 57. Thereby, the display case 14 of the rotation indicator 4 is accommodated in the display accommodating portion 17 of the device main body 1.

  Thus, also in this electronic register, as in the first embodiment, the support mechanism 50 that supports the rotation display 4 so as to be movable in the vertical direction with respect to the device main body 1 supports the rotation display 4 in the vertical direction. Since the support member 51 that expands and contracts in a plurality of stages along the direction and the support attachment portion 52 that holds the support member 51 in the display storage portion 17 of the device main body 1 so as to be able to appear and retract, the rotation indicator 4 is provided. Even if it is formed large, the entire apparatus can be made compact without being affected by the length of the support member 51.

  That is, in this electronic register, the length of the support member 51 can be shortened by contracting the support member 51 in a plurality of stages, so that the support member 51 can be stored compactly with respect to the device main body 1. Even if the length of the support member 51 when stored is shortened, the support member 51 can be elongated by extending it in a plurality of stages, so that the rotary indicator 4 can be reliably disposed above the device main body 1.

  Thereby, even if the rotation indicator 4 is formed large, the entire apparatus can be configured compactly without being affected by the length of the support member 51. Also in this case, in order to make the information displayed on the display panel 15 of the rotary display 4 easy to see, the display panel 15 can be formed large and the display panel 15 can be enlarged. 15, even if the display case 14 is formed large, the length of the support member 51 when contracted can be shortened, so that it is not necessary to form the device main body 1 large, and the entire device It can be configured compactly.

  In this case, the support member 51 of the support mechanism 50 has a different diameter. And a cylindrical restricting portion 55 that mutually restricts the drawing position when being pulled out, so that the second cylindrical portion 54 having a small diameter among the plurality of cylindrical portions 53 and 54 has a large diameter. The support member 51 can be shortened by being inserted into one cylindrical portion 53, and the support member 51 is lengthened by relatively pulling out the first and second cylindrical portions 53 and 54. Even if the support member 51 is lengthened, the length can be reliably maintained by the tube restricting portion 55.

  In other words, the cylinder restricting portion 55 is provided on the inner peripheral surface of the first cylindrical portion 53 along the axial direction thereof, and on the inner peripheral surface of the first cylindrical portion 53 in the circumferential direction. Is provided on the outer peripheral surface of the second cylindrical portion 54 that faces the inner peripheral surface of the first cylindrical portion 53 and the position restricting guide groove 53b that is provided along the extension guide groove 53a. Since the guide protrusion 54a that moves in the guide groove 53a and moves in the position restricting guide groove 53b is provided, the support member 51 can be expanded and contracted reliably and well, and when the support member 51 is stretched Furthermore, the extended state of the support member 51 can be maintained by inserting the guide protrusion 54a into the position restricting guide groove 53b.

  That is, in the support member 51, the guide protrusions 54 a of the second cylindrical portion 54 move in the expansion / contraction guide groove 53 a of the first cylindrical portion 53, so that each cylindrical portion 53, 54 is moved in the axial direction. Accordingly, the length of the support member 51 can be expanded and changed. Further, when the support member 51 is stretched, the guide protrusion 54a of the second cylindrical portion 54 is inserted into the position restricting guide groove 53b from the expansion / contraction guide groove 53a of the first cylindrical portion 53 and moves in the rotation direction. By doing so, it is possible to prevent the first and second cylindrical portions 53 and 54 from moving in the axial direction, and thereby the extended state of the support member 51 can be reliably and satisfactorily maintained. .
