Description

  The present invention relates to a date stamp unit and a rotation stamp unit. For example, the present invention can be applied to a date stamp unit and a rotation stamp unit that perform date adjustment by automatically adjusting a print belt for date stamps and rotation marks.

  Conventionally, date stamps and rotation stamps are well known and are widely used especially in offices.

  Conventional general date stamps have a date stamp body and a slide type outer frame (hereinafter also referred to as a slide frame) that fixes the printing surface, and the user manually moves the slide frame relative to the date stamp body. For example, the date is adjusted by manually rotating multiple print belts with year, month, day, time, etc., and the date on the print surface is fixed by manually moving the slide frame again after setting the date. I try to let them.

  As described above, the general date stamp is manually set by the user. However, in order to eliminate the trouble of manual date setting by the user, for example, as described in Patent Document 1 There is a technology that automatically sets the date stamp.

  The technology described in Patent Document 1 includes a timekeeping circuit that always keeps time, and a date setting device that sets the date type on the printing surface of the date stamp by an output signal of the timekeeping circuit, and has a stamping force that pushes the date stamp into the device. It converts to a date type change drive source, and changes a date type by this.

Japanese Utility Model Publication No. 59-48864

  By the way, users who use date stamps need to avoid the trouble of daily date adjustment and incorrect date alignment, so they strongly desire to automatically and accurately adjust the date stamp. It is out.

  For example, it is desirable that a user of an office or the like attaches a date stamp to the controller when leaving the previous day and the date stamp is automatically set to the correct date when he / she goes to work the next day.

  In the technique described in Patent Document 1 described above, the date is mechanically adjusted using the stamping force of the date stamp. When the date stamp is used, the user puts the date stamp on the apparatus for date setting. Pushing work is required, and automatic date adjustment is not performed. Therefore, even if the technique described in Patent Document 1 is used, there is a problem that it is not possible to automatically perform date setting of the date stamp without saving the user's trouble.

  In addition, in order to perform accurate date setting, it is necessary for the controller to correctly grasp the marking positions such as the month and date imprinted on the print belt and rotate each print belt.

  For example, in the rotation control of the print belt, when adjusting the rotation amount of the gear according to the pitch of the engraving, even if the rotation amount of the gear is adjusted, there is a slight load when the print belt can be rotated. The print belt may move just by being added, and the date may not always be correctly led to the print surface. Further, once the marking position is deviated, the subsequent rotation of the printing belt is also deviated, and accurate date setting may not be performed.

  Further, as a method for accurately determining the position of the print belt, for example, it is conceivable to newly provide a mechanism for accurately grasping the stamp position of the date stamp print belt. However, when such a mechanism is provided, there is a problem that the configuration scale of the date stamp unit is increased and complicated.

  In addition, it is necessary to fix the date on the printing surface with the slide frame, but even if the slide frame is tightened, the print belt rotates slightly, so when the date stamp is removed from the controller, The printed parts such as the month and date of the surface are not neatly arranged in a line, and the printing of the month and date may be slightly shifted. For this reason, when using date stamps, it is desired to make fine adjustments so that the prints on the print surface are aligned to correct the positional deviation of the print on the print surface.

  The present invention has been made in view of the above problems, and can accurately grasp the stamp position of the date stamp print belt with a simple configuration, and can automatically and accurately set the date stamp date. A date stamp unit and a rotation stamp unit are provided.

  In order to solve such a problem, the date stamp unit according to the first aspect of the present invention is configured such that the rotation of the plurality of print belts is restricted or permitted by the relative movement of the slide frame with respect to the date stamp body. A date control device that adjusts the date by rotating the date stamp rotating stamped body stored in the date stamp storing portion by the control of the control unit having a clock function and the date stamp having the stamp (1) Each printing belt of date stamp has one or a plurality of detected parts for recognizing the respective positions. (2) The date control device is rotated by a belt rotation mechanism. It has a detection part which detects each detected part of each printing belt to perform.

  The rotation mark unit of the second aspect of the present invention includes a rotation mark having a rotation mark body in which rotation of the plurality of print belts is restricted or permitted by the relative movement of the slide frame with respect to the rotation mark body; In a rotation mark unit comprising a rotation control device that rotates a rotation mark body of a rotation mark stored in the rotation mark storage part to fit a desired printing part under the control of a control unit having a clock function, (1) Each print belt of the rotation mark has one or a plurality of detected portions for recognizing the respective positions, and (2) each rotation belt is rotated by a belt rotation mechanism. It has a detection part which detects a detection part, It is characterized by the above-mentioned.

  According to the present invention, it is possible to accurately grasp the marking position of the date stamp on the print belt with a simple configuration, and to automatically and accurately set the date of the date stamp.

(A) 1st Embodiment Below, 1st Embodiment of the date stamp unit and rotation stamp unit which concern on this invention is described, referring drawings.

  The first embodiment exemplifies an embodiment in which the present invention is applied to a date stamp unit that automatically adjusts the date stamp printing belt and accurately matches the date stamp date.

(A-1) External configuration FIG. 1 is an external view showing an image of an external configuration of a date stamp unit according to the first embodiment. As shown in FIG. 1, the date stamp unit 3 according to the first embodiment includes a date stamp 1 and a controller 2.

  The date stamp 1 is a rotating date stamp having a plurality of printing belts on which printing of year, month, day, etc. is imprinted. When the date stamp 1 is attached to the controller 2, it receives the rotational drive of the controller 2, and the date is adjusted by rotating the print belt. As the date stamp 1, an existing rotation date stamp may be used, but in the first embodiment, a dedicated rotation date stamp for rotating the print belt by the rotational driving force from the controller 2 is used. The configuration of this dedicated date stamp 1 will be described later.

  The controller 2 automatically changes the date appearing on the printing surface 13 of the date stamp 1 by rotating the print belt of the date stamp 1 attached in accordance with the date of the clock unit included therein. The controller 2 includes a date stamp storage unit 20 that stores the date stamp 1. When the date stamp 1 is stored in the date stamp storage unit 20, the date stamp 1 is set as a date adjustment target.

  FIG. 1A is a configuration diagram in a state in which the date stamp 1 is taken out from the controller 2. When the date stamp 1 is used, the date stamp 1 is removed from the controller 2 and used as shown in FIG.

  FIG. 1B is a configuration diagram of a state in which the date stamp 1 is attached to the controller 2. For example, the date stamp 1 is stored in the controller 2 after the end of business. When the date of the clock unit is changed in this state, the controller 2 automatically rotates the date stamp 1 print belt to set the date.

  The external configuration of the controller 2 shown in FIGS. 1A and 1B is an example, and is not limited to this external configuration. Accordingly, in FIGS. 1A and 1B, the date stamp storage unit 20 of the controller 2 is illustrated on the left side of the central part, but may be the right end or the left end, for example. 1A and 1B exemplify the horizontal type of the date stamp 1, the date stamp 1 may be inserted vertically or obliquely.

(A-2) Configuration of Date Stamp 1 FIG. 2 is an explanatory diagram illustrating the configuration of the date stamp 1. 2A and 2B are external views of the date stamp 1, and FIG. 2C is a perspective view of the inside of the date stamp 1 as viewed from above.

  2A and 2B, the appearance of the date stamp 1 is as follows: the date stamp body 11, the slide frame 12, the print surface 13, a pair of first convex portions 14 on the opposite side surface, and a pair of opposite side surfaces. It has the 2nd convex part 15, the long hole 16, and the shaft 18 at least.

  Further, in FIG. 2C, the date stamp 1 includes therein a rotating stamped body in which three print belts 17a to 17c in which, for example, year, month, date, etc. are imprinted are arranged in three rows. ing. A rotation drive mechanism of the rotary printing body for rotating the print belts 17a to 17c will be described later.

  A slide frame 12 is coupled to the front end of the date stamp main body 11. The slide frame 12 has a window part (for example, a through-hole part) for projecting the print part of the print belts 17a to 17c. The printing surface 13 is fixed to the tip of the slide frame 12, and the print belts 17a to 17c exposed from the window portion of the slide frame 12 and the master printing body are coupled to each other so that the date stamp is attached. Can provide.

  In the first embodiment, the date stamp 1 in which the master stamp is fixed to the slide frame 12 is exemplified. However, the date stamp 1 can be widely applied to rotation stamps in which the master stamp is not fixed.

  The slide frame 12 has a pair of first convex portions 14 on opposite side surfaces. Moreover, the date stamp main body 11 has a pair of second convex portions 15 on opposite side surfaces. In FIG. 2, the second convex portion 15 is illustrated as being located at the lower portion of the date stamp main body 11, but may be provided at the upper portion of the date stamp main body 11 or the central portion of the date stamp main body 11. Good.

  When the date stamp 1 is stored in the controller 2, the first convex portion 14 and the second convex portion 15 can move the slide frame 12 and the date stamp main body 11 relative to each other to rotate the print belts 17 a to 17 c. It contributes to making it.

  Further, when removing the date stamp main body 11 from the controller 2, the first convex portion 14 and the second convex portion 15 relatively move the slide frame 12 to the original position to limit the rotation of the print belts 17a to 17c. It contributes to the state.

  Further, the slide frame 12 has a shaft body 18 (for example, a bolt) and a long hole 16 on the opposite side surface. Here, the date stamp main body 11 and the slide frame 12 are joined by, for example, a hole in the date stamp main body 11, a shaft 18 inserted into one long hole 16 of the slide frame 12, and a hole in the date stamp main body 11. The shaft body 18 is passed through the shaft body 18, the shaft body 18 is passed through the other long hole 16 of the slide frame 12, and the shaft body 18 is screwed to be coupled.

  By connecting the slide frame 12 to the date stamp main body 11, the slide frame 12 can be moved relative to the date stamp main body 11.

  As shown in FIG. 2A, when the slide frame 12 relatively moves in the direction of the date stamp main body 11, the window portion of the slide frame 12 fits into the print belts 17a to 17c, and the print surface is fixed. At this time, each of the print belts 17a to 17c is in a state where rotation for date setting is restricted (hereinafter referred to as a belt rotation restricted state).

  On the other hand, as shown in FIG. 2 (B), when the slide frame 12 moves relatively away from the date stamp main body 11, the fixing of the print belts 17a to 17c by the slide frame 12 is released. At this time, the print belts 17a to 17c are in a state in which the print belts 17a to 17c can be rotated for date adjustment (hereinafter referred to as a belt rotatable state).

  Inside the date stamp main body 11, there are a plurality of print belts 17 a to 17 c on which year, month, day, and the like are imprinted, and a rotation drive mechanism for rotating the print belts 17 a to 17 c.

  Each of the print belts 17a to 17c is configured to have, for example, 32 convex portions, and the year, month, and day are imprinted on each convex portion. Hereinafter, one convex portion of the print belts 17a to 17c will be described as one frame. The number of convex portions of the print belts 17a to 17c is not particularly limited.

  Further, each of the print belts 17a to 17c has a detected portion 171 as shown in FIG. The detected portion 171 is for causing the controller 2 described later to grasp the positions of the print belts 17a to 17b. For example, the detected portion 171 is configured by a protruding portion having one of 32 protruding portions that is higher than the other protruding portions. The controller 2 can detect the positions of the print belts 17a to 17c by detecting the detected part 171. Based on the detected position of the detected part 171, a print unit corresponding to the date setting is prepared. The print belts 17a to 17c can be driven to rotate so as to be exposed.

  2D illustrates the case where each of the print belts 17a to 17c has one detected portion 171, two or more may be provided.

  In the first embodiment, the date stamp 1 includes three print belts 17a to 17c. However, when the present invention is applied to a rotation stamp, at least one print belt is provided. It can be widely applied to the rotation mark provided.

  Here, in the conventional date stamp, an operation rotor for rotating the print belts 17a to 17c protrudes, and the user rotates the print belts 17a to 17c by manually rotating the operation rotor. The date is adjusted.

  On the other hand, in the first embodiment, the operation rotor of each of the print belts 17a to 17c like the conventional date stamp is not protruded. By preventing the operation rotors of the print belts 17a to 17c from protruding, it is possible to prevent easy date adjustment by the user and to prevent date tampering. Further, if the operation rotor is configured to be rotatable only when the date stamp 1 is set on the controller 2, date adjustment without using the controller 2 becomes impossible, which is useful in terms of preventing date falsification. .

  From the viewpoint of preventing date alteration, a predetermined key may be provided so that the print belt 42 is not easily exposed. If the key is opened only when the date stamp 1 is set in the controller 2, an operation for opening the key becomes unnecessary and good date falsification prevention performance can be exhibited.

(A-3) Position Confirmation Mechanism FIG. 3 is a configuration diagram showing a configuration of a rotation drive mechanism that rotates the print belts 17a to 17c of the date stamp 1. FIG. 3 is a perspective view of the internal configuration of the date stamp 1 in a state where the belt can be rotated as viewed from the side.

  In FIG. 3, the date stamp 1 has at least a first rotating wheel 31, a second rotating wheel 32, a position confirmation mechanism 33, and a stamping surface pushing portion 34.

  The position confirmation mechanism 33 receives rotational driving from the belt rotating mechanism 26 of the controller 2 and rotationally drives the print belts 17a to 17c. The position confirmation mechanism 33 is configured to rotate the print belts 17a to 17c while checking the marking positions (positions of the print portions) of the print belts 17a to 17c by sending out the print portions one frame at a time. is there.

  The first rotating wheel 31, the second rotating wheel 32, and the stamping surface pushing portion 34 guide rotation of the print belts 17 a to 17 c while tensioning the print belts 17 a to 17 c rotated by the position confirmation mechanism 33. It is.

  For example, a roller or the like can be applied to the first rotating wheel 31 and the second rotating wheel 32. The first rotating wheel 31 is provided on the side close to the slide frame 12, and the second rotating wheel 32 is a slide frame. It is provided on the side far from 12.

  For example, a push plate or the like can be applied to the stamp surface pushing portion 34. When the belt is in a rotatable state, the stamping surface pushing portion 34 guides the rotation of the print belts 17a to 17c at the tip of the date stamp 1. In the belt rotation restricted state, the print portions of the print belts 17 a to 17 c are exposed from the window portion 41 of the print surface 13.

  FIG. 4 is a perspective view illustrating a configuration example of the position confirmation mechanism 33. FIG. 5 is an explanatory diagram for explaining how the position confirmation mechanism 33 sends out the print belts 17a to 17c.

  As shown in FIG. 4, in the position confirmation mechanism 33, a fitting portion 331 that fits the convex portions of the print belts 17 a to 17 c frame by frame and a gear portion 332 that receives rotation from the controller 2 are integrally coupled. It is a thing.

  When the date stamp 1 is housed in the controller 2 and the belt can be rotated, the gear portion 332 of the position confirmation mechanism 33 is engaged with the gear constituting the belt rotation starting mechanism 26 of the controller 2. Further, when the gear portion 332 receives rotational driving from the belt rotation driving mechanism 26 of the controller 2, the gear portion 332 rotates, and the fitting portion 331 integrated with the gear portion 332 also rotates.

  At this time, as shown in FIG. 5, the fitting portion 331 fits the convex portions of the print belts 17 a to 17 c one frame at a time, and sends out one frame at a time as it rotates.

  Thus, the fitting part 331 sends out the print belts 17a to 17c frame by frame, so that the marking positions (convex parts) of the print belts 17a to 17c can be accurately grasped. Therefore, the relationship between the rotation amount of the gear related to the rotation control by the controller 2 and the marking positions such as the year, month, and date printed on the printing belts 17a to 17c can be correctly adjusted, and the deviation of the marking position can be corrected. Can be prevented.

  Here, the fitting part 331 shown in FIG. 4 and FIG. 5 illustrates a case where seven convex parts are sent out per rotation of the position confirmation mechanism 33, but the number of pieces sent out by the fitting part 331 per rotation is As long as the rotation speed of the gear according to the rotation control of the controller 2 can be adjusted, there is no particular limitation.

  Moreover, the fitting part 331 is comprised from the several wing | blade provided radially centering on the axis | shaft, and the shape formed by adjacent wing | blades is trapezoid shape. This is because when the convex portions of the print belts 17a to 17c are rectangular or trapezoidal, when the first rotating wheel 31 or the second rotating wheel 32 is fed into the fitting portion 331, the fitting condition with the fitting portion 331 is obtained. The engraving position can be confirmed accurately.

  In addition, the structural example of the position confirmation mechanism 33 shown in FIG. 4 has illustrated what sends out one printing belt 17a-17c. As described above, the date stamp 1 of the first embodiment includes the three print belts 17a to 17c. In this case, the three position confirmation mechanisms for feeding the print belts 17a to 17c are used. 33 can be arranged side by side.

  3 illustrates the case where the position confirmation mechanism 33 is positioned below the date stamp main body 11. However, if the convex portions of the print belts 17a to 17c can be fitted, where is the position of the position confirmation mechanism 33? For example, you may make it arrange | position to the upper part of 11 of a date stamp main body. Moreover, although the number of parts increases, you may make it provide two or more mechanisms which send out printing belt 17a-17c by a fitting part.

(A-4) Printing surface correction mechanism Next, a printing surface correction mechanism that corrects the positional deviation of the printing portion exposed on the printing surface 13 of the date stamp 1 will be described with reference to FIGS. 6 and 7.

  The printing surface correction mechanism determines the position of the printing unit exposed to the window by suppressing the rotation of the rotary printing member when exposing the printing unit of the rotary printing member to the window portion of the slide frame. . The printing surface correction mechanism includes the printing surface pushing portion 34, the printing belts 17a to 17c, and the inner mechanism of the slide frame 12 as constituent elements.

  Hereinafter, the configuration of the slide frame 12 will be described with reference to FIG. 6, and the configuration of the printing surface correction mechanism and the operation of correcting the position of the printing surface 13 will be described with reference to FIG.

  FIG. 6 is a configuration diagram showing the configuration of the slide frame 12 for the date stamp 1. 6A is a front perspective view of the slide frame 12, FIG. 6B is a rear perspective view of the slide frame 12, and FIG. 6C is a rear front view of the slide frame 12. FIG. 4D is a side sectional view of the slide frame 12.

  As shown in FIGS. 6A and 6B, the slide frame 12 includes a pair of first convex portions 14 on the opposite side surface, a long hole 16 through which the shaft body 18 penetrates, and a print portion of the print belts 17a to 17c ( And at least a window portion 41 that exposes the convex portion. In addition, the slide frame 12 has a misalignment prevention unit 42 inside the slide frame 12 as shown in FIG.

  The window portion 41 is a window (opening) that exposes the printing portions of the printing belts 17a to 17c pushed out by the stamping surface pushing portion 34 in the belt rotation restricted state. The opening of the window portion 41 has a rectangular shape. For example, in FIGS. 6A to 6C, when the vertical direction of the slide frame 12 is the y direction and the horizontal direction is the x direction, the opening length in the x direction is Is longer than the opening length in the y direction.

  The misregistration prevention unit 42 prevents misregistration of the printing unit exposed from the window 41 of the printing surface 13 in the belt rotation restricted state. For example, as shown in FIG. 6D, the misregistration prevention unit 42 has a structure that forms a step at the edge of the opening in the x direction of the window 41 of the printing surface 13 inside the slide frame 12.

  When the misalignment prevention unit 42 has such a configuration, the print belts 17 a to 17 c can be sandwiched between the misalignment prevention unit 42 that is stepped from the window 41 and the stamping surface extrusion unit 34. Therefore, the movement of the printing belts 17a to 17c can be suppressed, and the positional deviation of the printing portion exposed from the window portion 41 can be prevented.

  FIG. 7 is an explanatory diagram for explaining the configuration of the printing surface correction mechanism and the operation for correcting the positional deviation of the printing surface 13. FIG. 7A shows a case where the belt can be rotated, and FIG. 7B shows a belt rotation restricted state.

  In FIG. 7, the shape of the stamp face extruding portion 34 has an inclined structure such that the thickness thereof decreases as it approaches the tip. Therefore, as shown in FIG. 7A, when the belt is in a rotatable state, the printing surface pusher 34 can smoothly guide the rotation of the print belts 17a to 17c.

  In addition, the leading end of the stamping surface pushing portion 34 has a length substantially equal to the width of the printing portion (convex portion) of the printing belts 17a to 17c. For this reason, as shown in FIG. 7B, when the belt rotation is restricted, the stamping surface pushing portion 34 accurately pushes the printing portion from the back side of the printing belts 17a to 17c and prints from the window portion 41 of the printing surface 13. Part can be exposed.

  Further, as shown in FIG. 7B, the position of the printing portion is determined by pressing the inside of the slide frame 12 with the side surfaces of the two printing portions (convex portions) adjacent to the printing portion exposed from the printing surface 13. Can be determined correctly. That is, since the printing part (convex part) adjacent to the exposed printing part serves as a stopper that stops the movement of the printing belts 17a to 17c, the position of the exposed printing part can be determined.

  Furthermore, as described above, the movement of the print belts 17a to 17c is stopped by sandwiching the print belts 17a to 17c between the misalignment prevention unit 42 and the stamping surface pushing part 34 that are stepped with respect to the window 41. Therefore, the position of the printing part exposed on the printing surface 13 can be fixed.

  Although FIG. 6D illustrates a structure in which the shape of the misregistration prevention portion 42 is a step at the edge of the opening in the x direction of the window portion 41, the print belts 17a to 17c are prevented from misalignment. Various configurations can be applied to the shape of the misregistration prevention unit 42 as long as the position of the exposed printing unit can be fixed by being sandwiched between the portion 42 and the window unit 41 and the stamping surface extrusion unit 34. be able to.

  For example, as shown in FIG. 7, the print belts 17 a to 17 c have the shape of the misregistration prevention unit 42 as an inclined portion in accordance with the shape of the stamping surface extruding portion 34 having an inclined portion whose thickness decreases as it approaches the tip. It is good also as a structure which pinches | interposes.

(A-5) Configuration of Controller 2 Next, the configuration of the controller 2 will be described with reference to the drawings.

  In FIG. 1, the controller 2 includes, as an external configuration, a date stamp storage unit 20 that stores the date stamp 1, and an operation unit 21 for the user to adjust the date of the date stamp 1 and the date and time of the clock function inside the controller 2. Is provided. Various operation means can be widely applied to the operation unit 21. For example, operation buttons, touch panel buttons, and the like can be applied.

  FIG. 8 is an internal configuration diagram illustrating an internal configuration example of the controller 2. FIG. 8A is a perspective view of the internal configuration of the controller 2 as viewed from above, and FIG. 8B is a side perspective view of the controller 2 when the date stamp 1 is attached.

  As shown in FIGS. 8A and 8B, the controller 2 includes at least an electric motor 51, a rotation transmission mechanism 52, a belt rotation mechanism 53, detection units 54-1 and 54-2, and a control unit 24.

  The electric motor 51 gives a rotational force to the rotation transmission mechanism 52 in order to rotate the print belts 17 a to 17 c that perform date setting under the control of the control unit 24. For example, a motor or the like can be applied to the electric motor 51. For example, the electric motor 51 causes the rotation direction to be rotated forward and backward between “day” and “month”.

  The rotation transmission mechanism 52 is composed of a plurality of gears, and transmits the rotation of the electric motor 51 to the belt rotation mechanism 53. The configuration of the rotation transmission mechanism 52 can take various configurations as long as the rotation can be transmitted to the belt rotation mechanism 53.

  FIG. 9 is a configuration diagram illustrating configurations of the electric motor 51 and the rotation transmission mechanism 52 illustrated in FIG. 8. FIG. 9A is a top view of the rotation transmission mechanism 52, and FIG. 9B is a side view of the rotation transmission mechanism 52. In the case of the example in FIG. 9, the rotation transmission mechanism 52 is configured by a gear train having at least three gears 521 to 523, and the rotation from the electric motor 51 is transmitted to the gear 523, and the gear 523 rotates. The rotation is transmitted to the belt rotation mechanism 53.

  The belt rotation mechanism 53 receives the rotation of the rotation transmission mechanism 52 and rotationally drives the print belts 17a to 17b.

  10 and 11 are configuration diagrams showing the configuration of the belt rotation mechanism 53 illustrated in FIG.

  10 and 11 show a case where, among the three print belts 17a to 17c, for example, the two print belts 17b and 17c indicating the month and the day are rotated. Of course, the three print belts 17a to 17c including the print belt indicating the year can be rotated by the operation of the belt rotating mechanism 53 described below.

  FIG. 10 shows a mechanism for rotating the print belt 17b indicating the month, for example. FIG. 11 shows a mechanism for rotating the print belt 17c showing the day, for example.

  As shown in FIGS. 10 and 11, the belt rotation mechanism 53 includes at least a gear 531, a clutch 532, a gear 533, a gear 534, a gear 535, a clutch 536, a counter unit 537, and a counter unit 538.

  The gear 531 receives the rotation from the rotation transmission mechanism 52 and transmits the rotation to the gear 533. The gear 531 has a plurality of (for example, four in FIG. 10) protrusions 539, and when the gear 531 rotates, the counter part 537 repels the protrusions 539 and counts the rotation amount of the gear 531. .

  The gear 535 receives rotation from the rotation transmission mechanism 52 and transmits the rotation to the gear 534 and the gear 533. Similarly to the gear 531, the gear 535 also has a plurality of protrusions 539. When the gear 535 rotates, the counter 538 repels the protrusion 539 and counts the number of rotations of the gear 535.

  The clutch 532 is a one-way clutch that fixes the rotation direction of the gear 531 in one direction. A gear 531 and a clutch 532 are fixed to the shaft, and the clutch 532 is disposed in the gear mechanism of the gear 531. For example, the gear 531 can rotate in the counterclockwise direction when receiving a rotational force in the counterclockwise direction. However, when the gear 531 receives the rotational force in the clockwise direction, the rotary clutch 532 receives the gear of the gear 531. Engage with a groove in the mechanism to stop the clockwise rotation of gear 531.

  The gear 533 receives the transmission of rotation from the gear 531 and rotates the print belt 17b. The gear 534 receives transmission of rotation from the gear 535 and further transmits rotation to the gear 533.

  The clutch 536 is a one-way clutch that fixes the rotation direction of the gear 535 in one direction. A gear 535 and a clutch 536 are fixed to the shaft, and the clutch 536 is disposed in a gear mechanism of the gear 535. For example, the gear 535 can rotate in the clockwise direction when it receives a rotational force in the clockwise direction. However, when it receives the rotational force in the counterclockwise direction, the rotation clutch 536 causes the gear mechanism of the gear 535 to rotate. And the gear 535 is stopped from rotating counterclockwise.

  The counter units 537 and 538 have switches that repel the projections 539 of the gears 531 and 535, and the switches repel the projections 539, thereby counting the rotation amount of the gears 531 and 535, and the count value. Is given to the control unit 24.

  The detection unit 54-1 gives a detection signal to the control unit 24 when detecting the detected portion 171 of the print belt 17c. Further, the detection unit 54-2 gives a detection signal to the control unit 24 when detecting the detected portion 171 included in the print belt 17b.

  FIG. 12 is an explanatory diagram illustrating a detection method of the detected unit 171 by the detection units 54-1 and 54-2.

  As shown in FIG. 12, the detecting units 54-1 and 54-2 have, for example, a switch for detecting the detected portion 171 under the print belts 17b and 17c, and the print belt on which the switch rotates. When the detected parts 171 of 17b and 17c are detected, the detection signal is given to the control part 24. As described above, the detection units 54-1 and 54-2 can grasp the position of the print belt by the physical contact of the switch, so that the detection accuracy can be improved.

(A-6) Functional Configuration of Controller 2 Next, the functional configuration of the controller 2 will be described with reference to the drawings.

  FIG. 13 is a block diagram illustrating a functional configuration of the controller 2. In FIG. 13, the controller 2 includes at least an adjustment unit 22, a clock unit 23, a control unit 24, and a belt rotation control unit 25.

  The clock unit 23 measures time. It can be widely applied if at least the current date is known. For example, a general electric timepiece or radio timepiece can be applied.

  The adjustment unit 22 is configured to change and adjust the date of the date stamp 1 and the date and time of the clock unit 23 in response to the operation of the operation unit 21 by the user. As a method of adjustment by the adjustment unit 22, a method of adjusting the year, month, and day by pressing the operation unit 21 for each of the year, month, and day of the controller 2 can be applied.

  The control unit 24 manages the function of the controller 2. The control unit 24 monitors the time counted by the clock unit 23 and adjusts the date of the date stamp 1 in accordance with the date change of the clock unit 23.

  Further, the control unit 24 can detect the positions of the print belts 17b and 17c by receiving the detection signals of the detected portions 171 of the print belts 17b and 17c from the detection units 54-1 and 54-2. .

  Further, the control unit 24 receives the counter values of the gears 531 and 535 from the counter units 537 and 538 and recognizes the rotation amounts of the gears 531 and 535.

  Under the control of the control unit 24, the belt rotation control unit 25 controls the rotation so that the print belts 17a to 17c have a desired date by driving the electric motor 51 when the clock unit 23 changes the date. The belt rotation control unit 25 stores a rotation amount corresponding to one pitch between the convex portions of the print belts 17b and 17c.

  Further, the belt rotation control unit 25 starts from the position detection of the detected portions 171 of the print belts 17b and 17c by the detection units 54-1 and 54-2, and then rotates according to the date setting. The positions of the print belts 17b and 17c are stored. Thereby, the current positions of the print belts 17b and 17c can be recognized.

  The belt rotation control unit 25 then detects the positions of the print belts 17b and 17c stored when the detection units 54-1 and 54-2 detect the positions of the detected portions 171 of the print belts 17b and 17c. The position is reset and the subsequent positions of the print belts 17b and 17c are stored again.

  The rotation amount corresponding to one pitch between the convex portions of the print belts 17b and 17c may be set in advance, or by detecting the position of the detected portion 171 of the print belts 17b and 17c. By dividing the number of convex portions from the length of one cycle of each of the print belts 17b and 17c recognized in advance, the rotation amount corresponding to one pitch of the convex portions of the print belts 17a to 17c is obtained. May be.

  When the date changes, the belt rotation control unit 25 drives the electric motor 51 by a rotation amount obtained by multiplying the rotation amount corresponding to one pitch by the desired number of days (or months).

  At this time, the belt rotation control unit 25 can know the count values (rotation amounts) of the gears 531 and 535 rotating from the counter units 537 and 538. As a result, the belt rotation control unit 25 confirms that the belt has been rotated by the amount of rotation necessary for date adjustment, and stops driving the electric motor 51 when this amount of rotation is reached.

  FIG. 14 is a flowchart showing belt rotation processing by the belt rotation control unit 25. FIG. 14 exemplifies a process in the case where the respective parts 17b and 17c are rotated in accordance with the date of the clock part 23 after the detected parts 171 of the respective print belts 17b and 17c are detected.

  It is assumed that the belt rotation control unit 25 recognizes the amount of rotation corresponding to one pitch between the convex portions of the print belts of the date stamp 1 as a premise.

  First, when the clock unit 23 gives a date change (step S101), the belt rotation control unit 25 starts driving the electric motor 51 (step S102).

  The rotation transmission mechanism 52 is rotated by driving the electric motor 51, the rotation from the rotation electric mechanism 52 is transmitted to the belt rotation mechanism 53, and the print belts 17b and 17c are rotated.

  When the print belts 17b and 17c rotate and the detection units 54-1 and 54-2 detect the detected portions 171 of the print belts 17b and 17c, the belt rotation control unit 25 resets the position of the print belt. (Step S103).

  Further, the belt rotation control unit 25 rotates the detection position of the detected unit 171 by the rotation amount necessary for date setting (step S104).

  Then, the belt rotation control unit 25 receives the counter values from the counter units 537 and 538, checks the rotation amounts of the gears 531 and 535 based on the count values (step S105), and when the required rotation amount is reached, the electric motor The driving of 51 is ended (step S106). If the rotation amount is not necessary, the electric motor 51 is continuously driven.

(A-7) Effect of First Embodiment As described above, according to the first embodiment, date setting of the date stamp 1 can be performed automatically and accurately.

  Further, according to the first embodiment, the print belts 17a to 17c are provided with the detected portion 171, and the detection portions 54-1 and 54-2 provided on the controller 2 side are connected to the detected portions 171 of the print belts 17a to 17c. By performing the detection, the positions of the print belts 17a to 17c can be accurately grasped with a simple configuration, and the size and complexity of the date stamp unit can be avoided.

  Furthermore, in the first embodiment, since the date stamp 1 includes the position confirmation mechanism 33, it is possible to accurately recognize the marking positions of the printing belts 17 a to 17 c, so that the correct printing unit is guided to the printing surface 13. be able to.

  In the first embodiment, since the slide frame 12 includes the misregistration prevention unit 42, the misalignment of the printing unit on the printing surface 13 can be corrected, so that the printing surface 13 that is neatly arranged is provided. be able to.

(B) Other Embodiments Although various modified embodiments have been described in the first embodiment described above, other modified embodiments will be described below.

(B-1) Modified Embodiment of Date Adjustment Processing by Belt Rotation Control Unit 25 In the first embodiment described above, in the belt rotation mechanism 53, in order to set the rotation direction of the gears 531 and 535 to one direction, The clutches 532 and 536 are provided.

  In general, for example, clutches 532 and 536 such as a one-way clutch have a high slip rate and may have a large error. Further, when the battery-type electric motor 51 is used, variations may occur depending on the battery voltage. Further, backlash can occur in forward / reverse inversion driving of gears.

  Therefore, in order to increase the printing belt conveyance accuracy, processing as shown in FIG. 16 is performed. As a result, the belt conveyance accuracy can be increased with minimum parts.

  In the first embodiment described above, the case where the print belts 17a to 17c are provided with one detected portion 171 has been exemplified. However, as shown in FIG. And two of the detected parts 171 and 172 may be provided.

  In this case, the belt rotation control unit 25 can perform a belt rotation process as shown in FIG. FIG. 16 illustrates a case where “day” is changed.

  In FIG. 16, when the date is received from the clock unit 23 (step S201), the belt rotation control unit 25 starts driving the electric motor 51 (step S202).

  When the print belt 17c is rotated by the drive of the electric motor 51, the detection unit 54-2 detects the detected unit 172 (step S203), and then detects the detected unit 171 (step S204).

  The belt rotation control unit 25 recognizes that the time difference between the detected portion 171 and the detected portion 172 is a rotation amount for rotating one frame of the convex portion of the print belt 17c (step S205). Therefore, the belt rotation control unit 25 rotates the electric motor 51 by the rotation amount corresponding to the number of frames necessary for date setting (step S206), and when the corresponding rotation amount is reached (step S207), the driving of the electric motor 51 is performed. Is finished (step S208).

  In addition, when changing "month", it can implement | achieve by rotating the electric motor 51 reversely and performing the process similar to FIG.

  By doing this, it is possible to detect the detected parts 171 and 172 while always feeding the belt at a constant speed. Therefore, the clutches 532 and 536 such as the one-way clutch start in an engaged state, so that an error occurs. There is little occurrence of backlash.

(B-2) In 1st Embodiment, the case where the to-be-detected part provided in the printing belt was higher than another convex part was illustrated. However, the type of the detected part and the type of the detection part are not limited to this.

  For example, you may make it provide the 1st to-be-detected part higher than another convex part, and the 2nd to-be-detected part higher than another convex part, but lower than a 1st to-be-detected part.

  Accordingly, the detection unit can detect one pitch section of the print belt by detecting the first detected portion having a high height and the second detected portion having a low height.

(B-3) Further, the detected portion of the print belt may be configured such that, for example, a magnet is embedded in the print belt and the detector detects the magnet as long as the position of the print belt can be specified. Thereby, there can exist an effect equivalent to 1st Embodiment.

(B-4) The mechanism for detecting the position of the print belt can be applied to all print belts of “year”, “month”, and “day” in the same manner as in the first embodiment.

  Since the “year” print belt rotates only once a year, the print belt position detection and belt feeding mechanism may not be provided.

(B-5) In the first embodiment, the description will be made on the assumption that the date stamp 1 and the controller 2 are associated with each other on a one-to-one basis. However, the controller 2 can cope with a plurality of date stamps 1 as well. Also good.

  In this case, identification information (for example, ID) for identifying itself is stored in an IC chip or the like for each of the plurality of date stamps 1, and the controller 2 reads the identification information that is attached, and based on this identification information Date adjustment management of each date stamp 1 may be performed. For example, the date when the previous date adjustment was performed for each date stamp 1 is stored, or the time for performing date adjustment (for example, one date stamp may be AM0 and another date stamp 1 may be AM1), Information such as restrictions (for example, not on weekends) may be set.

  On the other hand, if the controller 2 determines that the date stamp 1 is not managed based on the identification information of the date stamp 1 attached, the controller 2 does not adjust the date of the date stamp 1 attached. Can be.

(B-6) An image sensor for imaging the printing surface 13 is provided at a position opposite to the marking surface, and the control unit 24 checks the date displayed on the printing surface 13 using the image sensor after the date adjustment work, for example, It may be determined whether the setting (current date) is the same as the date shown on the printing surface 13. If they are not the same, the difference between the two is calculated, and the belt rotation control unit 25 is instructed to rotate the rotor with the date stamp 1 according to the difference. Thereby, the printing surface 13 can be in a more accurate state.

(B-7) Of course, the date stamp 1 can be applied to a rotation stamp. In this case, the clock unit 23 is not particularly necessary, and the control unit 24 may adjust the printing surface 13 according to a predetermined rule. Further, the print surface 13 may be adjusted based on a user instruction input from the adjustment unit 22.
