At the same time, the function switch 8 functions as a switch for electrical mode switching. Then, by this switching operation, a lamp (not in the “OFF” position) 12 arranged beside the function switch 8 is turned on to display the switching position.

The ribbon cartridge 11 is configured to be detachable from the apparatus main body 5, so that the entire case can be replaced when the ink ribbon C is consumed. As shown in FIG. 2, a take-up reel 13 is provided at one end of the ribbon cartridge 11 and a take-out reel 14 is provided at the other end, and the ink ribbon C is taken out from the take-up reel 14 and is almost "L". It is bent in a letter shape and wound on the take-up reel 13. The ink ribbon C bent in an "L" shape
In the travel route, a printing portion faces a short side portion and an exposure portion faces a long side portion. In this case, the ink ribbon C and the plate making sheet B simultaneously face the printing section, and the printed ink ribbon C faces the exposure section.

The ink ribbon C is composed of a transparent ribbon tape and ink applied thereto.
m-thick one is used. When printing is performed on the ink ribbon C in the printing unit, the ink portion is transferred to the plate-making sheet B. As a result, a negative image in which the ink characters are peeled off is formed on the ribbon tape of the ink ribbon C, and a positive image on which the ink characters are adhered is formed on the plate making sheet B. Then, the ink ribbon C is sent to the exposure unit on the other side to use the ink ribbon as a mask, while the plate-making sheet B is
It is also sent out of the device in order to stick it on the created seal.

As shown in FIG. 33, the plate making sheet B is formed by laminating a base sheet Ba and an adhesive sheet Bb, and is formed in a strip shape as a whole. A cut line Bc is formed in the adhesive sheet Bb in a square shape, and a square portion of the adhesive sheet Bb peeled off from the base sheet Ba along the cut line Bc,
The seal character label Bd is attached to the back of the seal. The stamp body A is prepared in several types having different shapes according to the use as the stamp. In correspondence with this, the plate-making sheet B is also provided with the shape of the stamp character label Bd (the shape of the cut line). ) Are available.

On the other hand, as shown in FIG. 32, the stamp body A has a thin sponge (urethane foam) Ab adhered to the tip of a stock (made of resin in the embodiment) Aa, and an ultraviolet light is applied to the sponge Ab. A resin base Ac that is not affected is stuck, and an ultraviolet curable resin that forms the stamp face Ad is stuck to the resin base Ac. The portion of the stamp body A corresponding to the stamp character is cured by exposing the portion of the stamp body A to the ultraviolet curable resin (the stamp surface Ad) with ultraviolet rays using the ink ribbon C as a mask. In this state, the seal body A
Is removed from the pocket 6 and washed, whereby the water-soluble uncured portion is washed out to complete the seal. Reference symbol Ae in the figure is a cap made of resin. It should be noted that an ultraviolet softening resin may be used in place of the above ultraviolet curing resin. In such a case, if the positive / negative of the ink ribbon C and the plate making sheet B are reversed, the same seal as in the embodiment can be produced. Can be.

As shown in FIG. 2, in the stamp making apparatus 1, the ink ribbon C wound around the unwinding reel 13 is guided to the printing unit via the first path pin 51, and further the second path pin It is guided to the exposure section via the first guide pin 53 and the first guide pin 53, and is wound on the take-up reel 14 from the exposure section via the second guide pin 54 and the tension pin 55. In the printing section, printing is performed on the ink ribbon C while extruding the ink ribbon C by a print head 56 and a platen roller 57 disposed so as to sandwich the ink ribbon C.
Further, in the exposure section, the ink ribbon C is sandwiched between the stamp body A by the pressing plate 58, and the stamp body A is exposed to ultraviolet rays.

As shown in FIG. 3, the mechanical unit 4 has a built-in ribbon feeder 61 for rotating the take-up reel 13 and the platen roller 57 to move the ink ribbon C. As shown in FIG. 4, the mechanical unit 4 includes a lid open link 62 a for locking and unlocking the open / close lid 7, a head moving link 62 b for separating the print head 56 of the printing unit from and away from the platen roller 57, A ribbon holding link 62c for moving the holding plate 58 of the exposure unit forward and backward;
The lid open link 62a and the head moving link 62
b and a main link 62d for operating the ribbon holding link 62c.

First, the ribbon feeder 61 will be described in detail with reference to FIG. Ribbon feeder 61
Is a drive motor 10 built in the lower side of the function switch 8.
1 as a power source, a reel shaft 102 fitted to the take-up reel 13, and a roller shaft 1 fitted to the platen roller 57.
03 is rotated. Drive motor 10
An output gear 105 is fixed to the first output shaft 104, a power transmission gear 106 meshes with the output gear 105, and a main gear 107 meshes with the power transmission gear 106. One of the main gears 107 is a reel reduction gear train 108.
To the reel shaft 102 and the other to the roller reduction gear train 1
Power is transmitted to the roller shaft 103 via the control shaft 09.

A clutch arm 110 is rotatably supported on the output shaft 104 of the drive motor 101, and a power transmission gear 106 is rotatably supported on the clutch arm 110. The clutch arm 110 is connected to the output shaft 1
The power transmission gear 106 meshes with the main gear 107 so as to be able to freely move away from the main gear 107.
That is, when the drive motor 101 rotates, the clutch arm 110 rotates, and the power transmission gear 106
7, and the power of the drive motor 101 is transmitted to the take-up reel 13 and the platen roller 57. vice versa,
When rotational power is input from the take-up reel 13 or the platen roller 57 while the drive motor 101 is stopped,
The power transmission gear 106 is repelled by the main gear 107 to release the engagement.

Thus, for example, when the stencil sheet B inserted by mistake is pulled out, the platen roller 57 easily rotates (reversely rotates) without receiving the load of the drive motor 101, thereby affecting the ink ribbon C. And only the plate-making sheet B can be easily pulled out. However, the clutch arm 110 may be rotated in conjunction with the switching of the function switch 8. The reel shaft 102 is a sliding shaft, and absorbs a change in the peripheral speed that increases as the ink ribbon C is wound up on the take-up reel 13 by causing a slip.

Next, the function link mechanism 62 will be described in detail with reference to FIGS. The function link mechanism 62 includes a frame 121 and a lid open link 6 rotatably supported in an upright state on the frame 121.
2a, a plate-shaped head moving link 62b rotatably supported on the frame 121, a plate-shaped ribbon holding link 62c supported on the frame 121 so as to be able to advance and retreat, and a rotatable on the frame 121. It includes a supported plate-shaped main link 62d, and a ribbon pressing cam 122 interposed between the main link 62d and the ribbon pressing link 62c. The various gears of the ribbon feeder 61 are as follows.
The main link 62d is provided between the frame 121 and the ribbon holding link 62c, and the main link 62d is provided along the lower side of the frame 121.

The input side of the main link 62d is engaged with the eccentric pin 123 of the function switch 8, and is rotated about the support shaft 124 by forward and reverse rotation of the function switch 8. Also,
On the output side of the main link 62d, a tongue piece 125 is formed at the tip, a first pin 126 is provided at the front end, and a second pin 127 is provided at the base of the tongue piece 125. And this tongue piece 125 engages with the lower part of the lid open link 62a,
The first pin 126 is engaged with the head moving link 62b, and the second pin 127 is engaged with the ribbon pressing link 62c via the ribbon pressing cam 122.

The lid open link 62a includes an open link main body 128 and a pair of support shafts 129, 129 protruding from both ends in the longitudinal direction of the open link main body 128, respectively.
A pair of hooks 130, 130 extending from both ends of the open link main body 128 toward the opening / closing lid 7, and a lever 131 extending downward from the open link main body 128 so as to correspond to the tongue of the main link 62d. And a switch operating portion 132 that bends and extends forward from the open link main body 128 to be integrally formed (see FIG. 8). A coil spring 133 is stretched between the lever portion 131 and the frame 121, and the lid open link 6
2a is rotationally urged in a direction in which the tip of the hook portion 130 is hooked on the hook receiving portion 7a of the opening / closing lid 7.

When the function switch 8 is turned from the "OFF" position to the "O"
When rotated to the “PEN” position, the tongue 1
25 pivots forward to push the lever 131 of the lid open link 62a against the coil spring 133, and the hook 1
The latch of the hook 30 on the hook receiving portion 7a is released.
On the other hand, a leaf spring 7b for stably pressing the stamp body A accommodated in the pocket 6 is attached to the back surface of the opening / closing lid 7, and when the hook portion 130 is released, the opening / closing lid 7 is accommodated in the pocket 6. Receiving the stamp body A that is present, it is flipped up (see FIGS. 5 and 8). Note that, even when the seal body A is not stored in the pocket 6, the open / close lid 7 is flipped up by the lock member 171 of the lock mechanism 63 described later by the “OPEN” of the function switch 8 (see FIG. 10).

When the lid open link 62a is released, the switch operating section 132 causes the detection end of the detection device 66 described later to protrude into the pocket 6. Then, when the user releases the function switch 8 rotated to the “OPEN” position, the function switch 8 is turned by the coil spring 133 through the lid open link 62a and the main link 62d.
Automatically returns from the “OPEN” position to the “OFF” position. On the other hand, when closing the opening / closing lid 7,
By pressing the opening / closing lid 7 against the pocket 6 against the position b, the lever 131 of the lid open link 62a gets over the lever receiving part 7a of the opening / closing lid 7 and is locked.

The head moving link 62b is turned around a support shaft 135 provided in a holding portion of the print head 56 with the print head 56 mounted on the tip end thereof. An engagement surface 136 with which the first pin 126 of the main link 62d abuts is formed at the tail end of the head moving link 62b, and a coil spring 137 is bridged between the head moving link 62b and the frame 121. The coil spring 137 urges the tip of the head moving link 62 b around the support shaft 135 toward the platen roller 57, and also urges the engagement surface 136 to press the first pin 126. . The engagement surface 136 has a first stationary surface 139 on the distal end side and a second stationary surface 140 on the tail end side that are arcs concentric with the support shaft 124 of the main link 62d with the inclined surface 138 interposed therebetween. When the print head 56 is separated from the platen roller 57 while the first pin 126 is in contact with the second stationary surface 140 and the first pin 126 is in contact with the second stationary surface 140, The print head 56 contacts the platen roller 57. When the ribbon cartridge 11 is to be attached or detached, the print head 56 is further rotated in a direction away from the platen roller 57 by using a jig (not shown).

As shown in FIG. 6, the function switch 8 is set to "O"
When the main link 62d is rotated from the “FF” position to the “input / plate making” position, the first pin 126 of the main link 62d moves from the second stationary surface 140 down the inclined surface 138 to the first stationary surface 139. The moving link 62b rotates, and the print head 56 is pressed against the platen roller 57. Conversely, when the function switch 8 is turned from the “input / plate making” position to the “OFF” position, the first pin 126
The second stationary surface 14 is moved upward from the stationary surface 139 on the inclined surface 138.
0, the head moving link 62b rotates against the coil spring 137, and the print head 56 is separated from the platen roller 57.

When the function switch 8 is further turned from the "input / plate making" position to the "exposure" position, the first pin 12
6 moves toward the first stationary surface 139, the contact state of the print head 56 with the platen roller 57 is maintained (see FIG. 7). Similarly, the function switch 8 is set to “O”
When it is turned from the “FF” position to the “OPEN” position,
Since the pin 126 moves before the second stationary surface 140,
The separated state of the print head 56 from the platen roller 57 is maintained as it is (see FIG. 5). The coil spring 13
7, when the print head 56 is in contact with the platen roller 57, the first pin 126 actually floats slightly from the first stationary surface 139, and the print head 5
6 is reliably maintained in contact with the platen roller 57.

The ribbon holding link 62c is formed substantially in the shape of a letter "T" as a whole, and guide grooves 142 formed at both left and right ends and a front end, respectively, are formed in the frame 12a.
The projections 143 are mounted on the frame 121 so as to be engaged with the three projections 143, respectively, and slightly float on the frame 121 so as to be movable forward and backward. Each guide groove 142 is formed in a keyhole shape, and a disc-shaped retaining portion is formed at the upper end of the projection 143 (not shown). It is mounted on the frame 121 by being aligned and pushed into the retaining portion, and guided by the elongated hole of the guide groove 142 to the protrusion 143 so as to be able to advance and retreat. Also, two support pins 144 and 144 are provided at both ends of the ribbon holding link 62c which escaped the guide groove 142.
The support pins 144 and 144 are provided on the holding plate 58 and the first and second guide pins 53 and 54.
(See FIG. 13).

At the intermediate position of the ribbon holding link 62c,
A spring mounting piece 145 whose tip is bent extends rearward, and a coil spring 146 is stretched between the spring mounting piece 145 and the frame 121. Coil spring 146
Urges the ribbon holding link 62c forward, that is, in the forward direction. At the front of the ribbon holding link 62c, an engaging portion 147 is extended so as to be branched, and the engaging portion 147 is attached to the ribbon holding cam 122.
Is in contact.

The ribbon pressing cam 122 is integrally formed with an upper cam portion 149 and a lower cam portion 150 in which two plate cams are overlapped, and the frame 1 is supported by a support shaft 151.
21 is freely rotatable. Lower cam part 1
50 has a circular shape with a part cut out in a fan shape, and the upper cam portion 149 has a half-moon shape. Then, the engaging portion 1 of the ribbon holding link 62c is attached to the peripheral end portion of the upper cam portion 149.
The second pin 127 of the main link 62d is engaged with the notched portion of the lower cam portion 150 (see FIG. 6).

In the state shown in FIG. 6, the function switch 8 is in the "input / plate making" position. When the function switch 8 is rotated from this state to the "exposure" position, the main link 62 is turned on.
The second pin 127 of d presses one end of the notch of the lower cam portion 150, and rotates the ribbon pressing cam 122 counterclockwise. By this rotation, the engaging portion 147 of the ribbon holding link 62c falls from the peripheral end portion of the upper cam portion 149 to the chord portion, and the ribbon holding link 62c is moved by the coil spring 146.
It is urged to move forward. At this time, the ribbon holding cam 122
Is configured to be freely rotatable, the coil spring 14
6 and is instantaneously rotated to a position where the chord portion of the upper cam portion 149 and the contact surface of the engaging portion 147 of the ribbon pressing link 62c come into full contact with each other. Also, due to this rotation, the other end of the notch of the lower cam portion 150
7 (see FIG. 7).

The above-mentioned guide groove 142 also serves as a stopper for regulating the forward end position of the ribbon holding link 62c.
3, the ribbon holding link 62c stops at the forward end position. Therefore, the above-mentioned upper cam portion 1
In a state where the engaging portion 147 of the ribbon holding link 62c is entirely in contact with the chord portion of the forty-nine 49, the urging force of the coil spring 146 does not actually act on this portion, and the engaging portion 147 Is slightly separated from the chord portion of the upper cam portion 149.

On the other hand, when the function switch 8 is rotated from the "exposure" position to the "OFF" position via the "input / plate making" position, the second pin 127 pushes the other end of the notch of the lower cam portion 150, The ribbon holding cam 122 is rotated clockwise. By this rotation, the engaging portion 147 of the ribbon pressing link 62c relatively returns from the chord portion of the upper cam portion 149 to the peripheral end portion, and the ribbon pressing link 62c is
Retreat against 46. In this state, the coil spring 14
The free-rotatable ribbon pressing cam 122 is stretched against the ribbon pressing link 62c biased to 6, and the ribbon pressing link 62c is maintained at the retracted position (see FIG. 4). When the function switch 8 is rotated from the “OFF” position to the “OPEN” position, the other end of the notch of the lower cam 150 with which the second pin 127 is in contact
Since it is substantially parallel to the moving direction of the pin 127, the ribbon pressing link 122 is maintained at the retracted position only by slightly rotating the ribbon pressing cam 122 clockwise (see FIG. 5).

Thus, the function switch 8 is turned "OFF".
When rotated from the position to the “OPEN” position, the hook 1
30 comes off and the opening / closing lid 7 can be opened.
When the print head 56 is rotated from the "F" position to the "input / plate making" position, the print head 56 presses the ink ribbon C against the platen roller 57 to be in a printable state, and is further rotated from the "input / plate making" position to the "exposure" position. Then, the pressing plate 58 presses the ink ribbon C against the stamp main body A, and becomes ready for exposure. If the lid 7 is accidentally opened during the exposure, or if the exposure is performed with the lid 7 opened, the ultraviolet rays leak to the outside, which is not preferable. Also, when printing, the open / close lid 7
Opening may cause jamming of the ink ribbon C.
Therefore, in the embodiment, a lock mechanism 63 that locks the opening / closing lid 7 in a closed state during the printing operation and the exposure operation, and prevents a transition to the printing operation and the exposure operation when the opening / closing lid 7 is opened. It has been incorporated.

The lock mechanism 63 is provided in the portion of the function switch 8, and the structure of the function switch 8 will be described here for easy understanding. As shown in FIG. 9, the function switch 8 has a mark 16 indicating a set position on the upper surface.
2, a click member 163 attached to the inner space of the dial 161, and an eccentric pin 123 that engages with the main link 62 d. The case 2 is rotatably attached to a seat plate 2 a. The click member 163 is curved and extends in the radial direction of the dial 161,
A pair of click arms 165 and 165 located in point symmetry
The circularity 165a at the tip of the click arm 165 is pressed against each click engagement part 166 formed on the seat plate 2a by the spring property of each click arm 165.

Each click engaging portion 166 has four convex portions 166a and three concave portions 166b toward the click arm.
The state in which the circular portion 165a of each click arm 165 is dropped (engaged) into the three concave portions 166b is the above-mentioned "OFF" position, "input / plate making" position, and "exposure". It corresponds to the position (see FIG. 9A). The middle position of the outermost projection corresponds to the “OPEN” position, and no click-like engagement is performed at the “OPEN” position (see FIG. 9B). As a result, the automatic return from the “OPEN” position to the “OFF” position is smoothly performed. Note that the “OFF” position and the “OPE
A rotation angle of 15 degrees between the position “N” and the position “O”
The rotation angle between the “FF” position, the “print” position, and the “exposure” position is 30 degrees.

On the other hand, the lock mechanism 63 includes a lock member 171 provided at the boundary between the function switch 8 and the pocket 6, as shown in FIGS.
Reference numeral 71 is attached to the seat plate 2a of the apparatus case 2 so as to be vertically movable while being urged upward by the lock spring 172. The lock member 171 includes a member main body 173 guided vertically movably by the seat plate 2a, a push arm 174 extending from the member main body 173 toward the pocket 6 and extending upward by bending, and a function switch 8 from the member main body 173. And a lock arm 175 that extends to the side and bends to extend upward.

The push arm 174 faces the lid seating portion 6a of the pocket 6 from below. When the opening / closing lid 7 is opened, the push arm portion 174 projects from the lid seating portion 6a. That is, when the cover 7 is opened, the lock member 171 is moved upward by the lock spring 172, and when the cover 7 is closed, the lock member 171 is moved downward against the lock spring 172. On the other hand, when the lock member 171 moves upward, the lock arm portion 175 enters the locking groove 176 formed in the side wall portion of the function switch 8 and prevents the function switch 8 from rotating. Conversely, when the lock member 171 moves downward, the lock arm portion 175 is disengaged from the locking groove 176 of the function switch 8, and the rotation inhibition of the function switch 8 is released.

In this case, the locking groove 176 is a long groove extending in the circumferential direction. When the function switch 8 is rotated between the "OFF" position and the "OPEN" position (this operation is not normally performed, ) Is allowed to rotate. Conversely, when the function switch 8 is rotated from the “OFF” position to the “input / plate making” position or the “exposure” position, the rotation is blocked. With this configuration, when the cover 7 is open, the rotation of the function switch 8 is prevented, and it is impossible to shift to the printing operation and the exposure operation.

The mechanism for locking the opening / closing lid 7 in the closed state during the printing operation and the exposure operation is provided by the main link 6 described above.
This is achieved by 2d and lid open link 62a. That is, when the function switch 8 is in the “input / plate making” position or the “exposure” position, the lid open link 62 a
Thereby, the opening / closing lid 7 is closed and locked. Thus, the exposure is not performed while the opening / closing lid 7 is open, and the opening / closing lid 7 is not opened while the exposure is being performed.

Next, the printing device 64 provided in the printing section will be described with reference to FIG. As described above, the printing device 64 includes the print head 56 that prints a seal character on the ink ribbon C, and the platen roller 57 that feeds the ink ribbon C in accordance with the printing operation of the print head 56.
Further, in the apparatus case 2 toward the contact portion between the print head 56 and the platen roller 57, there are formed a feed passage 181 into which the above-described plate making sheet B is fed and a feed-out passage 182 through which the plate making sheet B is fed out. ing. The insertion port 9a opened to the outside is formed at the upstream end of the feeding passage 181. The outlet 9b opened to the outside is formed at the downstream end of the sending passage 182.

The platen roller 57 is a driving roller as described above, and unwinds the ink ribbon C from the unwinding reel 14 and holds the plate making sheet B between the print head 56 and the ink ribbon C and the plate making roller. The sheet B is made to face the print head 56 in a state of being overlapped. Print head 5
Reference numeral 6 denotes a thermal head which transfers the ink applied to the ribbon tape of the ink ribbon C to the plate B by thermal transfer. Due to this transfer, a portion corresponding to the seal character is peeled off from the ink ribbon C, and the transparent ribbon tape ground appears on the portion, while the peeled ink adheres to the plate making sheet B as a seal character.

A sensor 183 for detecting the insertion of the plate-making sheet B and the feed reference position faces the feeding path 181, and the plate-making sheet B inserted into the feeding path 181.
Is sent by the platen roller 57 based on the detection result of the sensor 183, and printing is started from the position of the leading end of the stamp character label Bd. A separation claw 184 is formed at the tip (upstream end) of the left wall constituting the delivery passage 182, and the separation claw 184 allows the ink ribbon C and the plate-making to be sent in an overlapped state. The sheet B is separated. Then, the ink ribbon C is sent to the exposure unit on the other side, and the plate making sheet B is sent out of the apparatus via the sending path 182.

Next, with reference to FIGS. 13 and 14, the exposure apparatus 65 provided in the exposure section will be described. The exposure device 65 includes a stamp surface Ad of the stamp body A set in the pocket 6.
And a pressing plate 58 provided between the ultraviolet light source 191 and the stamp surface Ad of the stamp body A. Seal surface Ad of stamp body A and presser plate 5
8 and the ultraviolet light source 191 are arranged in parallel with each other with a gap therebetween, and an ink ribbon C is arranged between the stamp face Ad and the holding plate 58. The holding plate 58 is made of a transparent resin or the like, and moves forward to press the ink ribbon C against the stamp surface Ad of the stamp body A.
That is, at the time of exposure, the stamp body A is
After the ink ribbon C is pressed against the stamped surface Ad, the ultraviolet light source 191 is turned on, and the ink ribbon C is
Exposure is performed using the mask as a mask (see FIG. 13).

The ultraviolet light source 191 is a self-heating hot cathode tube called a semi-hot tube, and is supported by a fluorescent tube holder 193 provided on a substrate 192 as shown in the front view of FIG. 15 and the plan view of FIG. ing. UV light source 191
A pair of thermal fuses 194 and 194 for detecting the life and failure of the ultraviolet light source 191 are arranged at the left and right ends of the fuse. Each thermal fuse 194 is formed in a cylindrical shape, is provided in a direction orthogonal to the longitudinal direction of the ultraviolet light source 191, and is in contact with the ultraviolet light source 191 from below. Each thermal fuse 194 is provided with a holding arm 1 extending from the fluorescent tube holder 193.
95, and is pressed against the ultraviolet light source 191 by a holding arm 195 having a spring property.

Although not shown, it is preferable to provide a reflector behind the ultraviolet light source 191 and to irradiate the ultraviolet light intensively forward. Further, the thermal fuse 194 may be provided separately from the ultraviolet light source 191 so that the heat of the ultraviolet light source 191 does not conduct to the thermal fuse 194. In such a case, the rising of the light amount of the ultraviolet light source 191 becomes good.

As shown in FIGS. 17 and 18, the holding plate 58 is made of a transparent resin or the like formed in a square shape.
Left and right holding plate holders 201, 201 at both ends in the longitudinal direction
Attached to. Also, each holding plate holder 201
Are attached so as to be inserted into two support pins 144 and 144 erected at each end of the ribbon holding link 62c (see FIG. 14). The pressing plate 58 is a pressing plate body 202 pressed against the stamp surface Ad of the stamp main body A.
A pair of upper and lower guide claws 203, 203 extending rearward from each end of the holding plate body 202, and a plate portion 204 extending from the holding plate body 202 between the pair of upper and lower guide claws 203, 203. The plate portion 204 is formed with a shaft projection 205 which is located at an intermediate position between the upper and lower sides of the holding plate 58 and guides the swinging movement of the holding plate 58 in the front-rear direction.

Although not shown in the drawing, the holding plate body 20
2 is slightly warped in the longitudinal direction on the side opposite to the stamp body A, that is, toward the ultraviolet light source side, and when the ink ribbon C is pressed against the stamp face Ad of the stamp body A by the pressing plate 58, the stamp face Ad is pressed. On the other hand, the ink ribbon C can be spread. Guide pieces 206, 206 extending upward are formed at both ends of the holding plate body 202, and each guide piece 206 is bent obliquely rearward. Thus, when the ribbon cartridge 11 is mounted, the ink ribbon C is appropriately guided between the pressing plate 58 and the stamp body A. Further, both ends of the presser plate body 202 are chamfered in an arc shape, and the ink ribbon C is bent at the chamfered portion 207 so as not to cause wrinkles during exposure (see FIG. 13). Reference numerals 208 and 208 in FIGS. 17 and 18 denote a pair of upper and lower ribs provided to increase the rigidity of the holding plate body 202.

On the other hand, each holding plate holder 201 is formed with a pair of upper and lower V-grooves 210 for guiding the pair of upper and lower guide claws 203 of the holding plate 58 in the front-rear direction. Groove 2 that guides to rotate freely
11 are formed. That is, the holding plate 58 has the guide claws 203 in the V-grooves 210 and the shaft projections 205
Are respectively engaged with the concave grooves 211, and are attached to the left and right holding plate holders 201, 201 so as to be able to advance and retreat in a front-rear direction for a small distance and to be swingable in a front-rear direction.
In this state, a pair of upper and lower spring pieces 21 extending from each holding plate holder 201 is attached to each outer end of the holding plate 58.
2,212 are pressed from behind, and the holding plate 5
8 is biased by the spring piece 212 toward the forward end position where the claw portion of the guide claw 203 comes into contact with the groove bottom portion of the V-groove 210.

When the ribbon holding link 62c moves forward from the state shown in FIG. 14 (FIG. 2), the two holding plate holders 201, 201 move forward, and the holding plate 58 faces the stamp surface Ad of the stamp body A. And move in parallel. The movement stroke of the ribbon holding link 62c is slightly longer than the distance between the holding plate 58 and the stamp surface Ad of the stamp body A,
When the ribbon holding link 62c reaches the forward position,
The pressing plate 58 and the stamped surface Ad of the stamp body A have already abutted, and the pressing plate 58 receives a reaction force from the stamped surface Ad, and slightly retreats relatively to each of the pressing plate holders 201. Since the retraction of the presser plate 58 is caused by the reaction force from the stamp surface Ad, the reaction force and the pressing force of each part of the presser plate 58 oppose each other, and the presser plate 5
8 is in contact with the stamp surface Ad of the stamp body A (FIG. 13).
reference). That is, the pressing plate 58 sandwiches the ink ribbon C and makes the ink ribbon C adhere to the stamp surface Ad of the stamp body A without any gap.

As shown in FIG. 18, each holding plate holder 201 is formed integrally with a guide pin holding portion 214 through which one support pin 144 is inserted. A ribbon sliding contact member 215 is attached. The ribbon sliding contact member 215 is formed in a half-moon cross section, and is disposed with its arc surface facing the holding plate 58 side. A pair of left and right support pieces 216 each having a round hole are formed at the upper and lower intermediate portions of the ribbon sliding contact member 215.
By being fitted into the pair of shaft projections 217 formed on the outside from outside, respectively, the ribbon sliding contact member 215 is attached so as to be swingable in the rotation direction with respect to the axis of the guide pin holding portion 214.

The guide pin holding portion 214 and the ribbon sliding contact member 215 are disposed outside the pressing plate 58 and the stamp body A (see FIGS. 14 and 17), and the guide pin holding portion 214 located on the right side. The ribbon sliding contact member 215 constitutes the first guide pin 53, and the guide pin holding portion 214 and the ribbon sliding contact member 215 located on the left side constitute the second guide pin 54, respectively. That is, the first guide pin 53 and the second guide pin 54
Accordingly, the ink ribbon C running between the press plate 58 and the stamp surface Ad of the stamp body A does not interfere with the ink ribbon C,
They are guided parallel to these.

Although the details will be described later, since the guide pin holding portion 214 forms a part of the holding plate holder 201, the first guide pin is moved with the advance of the holding plate (ribbon holding link 62c) 58. The 53 and the second guide pin 54 also move in the same direction. This movement loosens the tension of the ink ribbon C stretched between the first and second guide pins 53 and 54, and the ink ribbon C is in a state where the tension is reduced, that is, in a state where vertical wrinkles are not generated. The stamp body A is pressed against the stamp surface Ad.

This state will be described in more detail with reference to FIGS. 2 and 13. Ink ribbon C running in FIG.
, A stronger tension acts on the take-up reel 13, and as described above, the ink ribbon C has an extremely thin tape, so that vertical wrinkles are generated. Therefore, if the ink ribbon C is pressed against the stamp surface Ad of the stamp body A as it is, the ink ribbon C is pressed against the stamp surface Ad while generating vertical wrinkles, and the stamp characters are distorted and exposed. On the other hand, if the ink ribbon C is loosened, the stamp characters are misaligned and exposed. Therefore,
As shown in FIG. 13, the first
The guide pin 53 and the second guide pin 54 are also moved forward to loosen the tension of the ink ribbon C, and at this time, the tension pin 55 applies tension with a weak force that does not cause vertical wrinkles on the ink ribbon C. ing.

In addition, the ink ribbon C in the exposure state shown in FIG.
As a result, the ink ribbon C is bent rearward at both ends of the holding plate 58, and the use of the chamfered portions 207 formed at both ends of the holding plate 58 prevents unnecessary wrinkles from occurring on the ink ribbon C.

Here, the path of the ink ribbon C will be described with reference to FIG. The ink ribbon C wound from the unwinding reel 14 is appropriately guided to the printing device 64 by the first path pin 51, further largely bent by the second path pin 52 from the printing device 64, and is subsequently bent by the first guide pin. It is appropriately guided to the exposure device 65 by the 53 and the second guide pin 54, and finally wound up on the take-up reel 13 via the tension pin 55. This route is at the time of traveling of the ink ribbon C and at the time of traveling standby.
As described above, the route at the time of exposure is different from that described above, and also differs when the device is carried as the ribbon cartridge 11. Here, before describing the path when the ribbon cartridge 11 is carried, the structure of the ribbon cartridge 11 itself including each reel and each pin will be described.

As shown in FIGS. 20 and 21, the ribbon cartridge 11 has a cartridge case 2 composed of a base plate 222 formed in an inverted “L” shape and a plurality of legs 223 extending from the base plate 222.
21, each reel and each pin are attached in a cantilever manner. The ribbon cartridge 11 is mounted on the apparatus main body 5 by fitting the respective legs 223 into the accommodating portions 5a of the apparatus main body 5 with the base plate 222 facing upward. The leg 223 is provided at each corner of the cartridge case 221 as shown in FIG.

An unwinding reel 14 is rotatably suspended from the short side end of the base plate 222,
A take-up reel 13 is rotatably suspended from the long side end. Further, a first path pin 51 with a reinforcing rib hanging from the base plate 222 is provided at the front of the unwinding reel 14, and a path changing member 224 configured to be able to advance and retreat in the front-rear direction is provided at the front thereof. Have been. In front of the take-up reel 13, a tension pin 55
Are urged by the coil spring 225 and are provided on the base plate 222 so as to be able to advance and retreat. As shown in FIG. 20B, the reel shaft 1 of the unwinding and winding reels 13 and 14 is provided in the accommodation portion 5a of the apparatus main body 5.
02, 226, print head 56, platen roller 57,
Inlet and outfeed passages 181, 182, second path pin 52, first and second guide pins 53, 54, holding plate 5
8, an ultraviolet light source 191 and the like are provided.

As shown in FIG. 21, an unwinding reel (the winding reel 13 is completely the same) 14 is provided with a cylindrical shaft portion 228 around which the ink ribbon C is wound, and extends at the upper end of the shaft portion 228. An upper engaging portion 229, and a lower engaging portion 230 extending from the lower end of the shaft portion 228. The lower engaging portion 230 is rotatably supported by the base plate 222 by the upper engaging portion 229. And is rotatably supported on the apparatus main body 5 side. The upper engaging portion 229 includes a cylindrical portion 231 and a flange-shaped crown portion 232 connected to the upper side of the cylindrical portion 231. Correspondingly, the cylindrical portion 231 is rotatably slidably contacted with the base plate 222. A portion 233 and a step 234 on which the lower surface of the crown 232 is seated are formed. The lower surface of the crown portion 232 and the step portion 234 are formed in a sawtooth shape, and the crown portion 232 is formed.
Is in contact (engagement) with the step portion 234, the unwinding reel 14 can rotate in only one direction.

In this case, when the ribbon cartridge 11 is mounted on the apparatus main body 5, the unwinding reel 14 is slightly pushed up, and the engagement between the crown 232 and the step 234 is released. It becomes rotatable. On the other hand, when the ribbon cartridge 11 is not mounted on the apparatus main body 5, the unwinding reel 14 is pressed down by its own weight, the crown 232 and the step 234 are engaged, and the unwinding reel 14 is prevented from rotating backward. work. This reverse rotation prevention prevents the ink ribbon C from being loosened.
Thus, the rotation of the unwind reel 14 is prevented in the direction opposite to the running direction of the ink ribbon C, and the unwinding reel 14 is prevented from rotating in the running direction of the ink ribbon C. Of course, take-up reel 13 and unwind reel 14
Both can be rotated in the direction in which the ink ribbon C is stretched. The ribbon cartridge 11 provided for replacement has a crown 232 on the upper surface of the base plate 222.
A plate (not shown) is provided for pressing the plate 34, and is packaged and raised in this state.

The path changing member 224 is similar to that shown in FIGS.
As shown in FIG. 1, a slider 236 slidably attached to a corner portion of the base plate 222, and a path change pin 237 integrated with the slider 236.
It is composed of The upper surface of the slider 236 is exposed to the outside and is flush with the upper surface of the base plate 222. The path change pin 237 is
Is moved in the front-rear direction along with the sliding of the take-up reel 13 and the take-out reel 14
The ink ribbon C stretched between them is stretched almost at a right angle. In this case, the ink ribbon C is stretched at a right angle until the ribbon cartridge 11 is mounted on the apparatus main body 5, and when mounted on the apparatus main body 5, the path change pin 237 is moved forward to the maximum. (See FIG. 22).

Thus, when the ribbon cartridge 11 is mounted, the path changing pin 237 and the tension pin 5
5 cooperate to regulate the path of the ink ribbon C so as not to interfere with the holding plate 58, the stamp body A, the second path pin 52, and the like, and the path change pin 237 and the first path pin 51 cooperate. In operation, the path of the ink ribbon C is regulated so as not to interfere with the print head 56, the platen roller 57 and the like.
Then, after the ribbon cartridge 11 is mounted, the path change pin 237 is moved, so that the ink ribbon C
Is in the above-mentioned traveling state and traveling standby state.

The tension pin 55 has a sliding contact portion 239 having a semicircular cross section and a support plate portion 2 for supporting the sliding contact portion 239.
40, and is urged in a direction to stretch the ink ribbon C by a coil spring 225 interposed between the base plate 222 and the coil spring 225. The spring force of the coil spring 225 is weak enough not to cause vertical wrinkles in the stretched ink ribbon C, and the tension pin 55 functions so that the ink ribbon C does not loosen. That is, in the ribbon cartridge 11 for replacement, as described above, the take-up reel 13
And the unwinding reel 14 is in the reverse rotation stopped state, and the ink ribbon C is stretched between the reels 13 and 14. The tension pin 55 abutting on the ink ribbon C is Prevents C from loosening.

In the exposure operation as described above, the holding plate 58 and the first and second guide pins 53 and 54 are
When simultaneously moving to the front of the seal body A side, the tension pin 55 prevents the ink ribbon C from being loosened.
And it is stretched to such an extent that vertical wrinkles do not occur. When it is not necessary to request the former function from the tension pin 55, the tension pin 55 may be provided on the apparatus main body 5 side. By doing so, the tension function of the tension pin 55 becomes more stable.

As shown in FIG. 23, the sliding contact portion 242 of the second path pin 52 and the sliding contact portion 239 of the tension pin 55 are formed in a middle-high shape like a general pulley, and are laid on a horizontal plane. The ink ribbon C traveling in the inclined state does not fall down from the sliding contact portions 239 and 242. Further, even if the sliding portions 239 and 242 and the ink ribbon C are not exactly perpendicular to each other, it is possible to prevent the ink ribbon C from running unevenly. That is, the ink ribbon C that comes into contact with the sliding portions 239 and 242 travels with its middle portion in the width direction slightly rising. Thereby, the second
Each sliding contact portion 24 of the path pin 52 and the tension pin 55
2, 239 and the ribbon sliding contact members 215 of the first and second guide pins 53, 54, which are configured to be swingable, so that the ink ribbon C always keeps a constant height position. , And the exposure device 65.

Next, a description will be given of the detection device 66 which is linked to the opening and closing of the opening / closing lid 7. The detection device 66 detects that the stamp body A is mounted in the pocket 6 and determines the type of the stamp body A. The stamp body A is prepared in various shapes such as a square stamp, a name stamp, a business stamp, an address stamp, and the like. These stamp bodies A have the same length but width. And thickness are different. In order to set such various stamp bodies A having different widths and thicknesses at fixed positions in the pocket 6 in the width direction and the thickness direction, in this embodiment, as shown in FIGS. 6 bottom surface 6b
Bosses 251, 251, 251, 251 are provided upright, and a correspondingly formed fitting hole Af is formed in the stamp body A for fitting the boss 251 (see FIG. 25).

Four bosses 251, 251, 251 and 25
1 are arranged in a “T” shape, and correspondingly, for example, two fitting holes Af and Af are formed in a square mark (FIG. 25).
(A)), the business seal has four fitting holes Af, Af, A
f and Af (FIG. 25B) are formed. As described above, the number and the depth of the fitting holes Af of the stamp body A are different depending on the type of the stamp body A, and various combinations of the stamps mounted on the pocket 6 are provided by the combination of the fitting hole Af and the boss 251. The body A is positioned so that the center of the stamp surface Ad always comes to the same position.

The back surface A of the stamp body A opposite to the stamp surface Ad
g, a plurality of lateral holes (type detection holes) Ah are formed at an intermediate position in the thickness direction, and the type of the stamp body A is changed in cooperation with a switch array 262 of the detection device 66 described later. It is determined (see FIG. 31). Note that a stamp character label Bd of the plate making sheet B separated from the ink ribbon C after printing and sent to the outside of the apparatus is stuck to the back surface Ag of the stamp body A, whereby the child hole Ah is hidden. ing.

As shown in FIGS. 26, 27 and 28, the detecting device 66 includes a switch holder (also serving as a wall surface of the pocket 6) 261 disposed so as to face the back surface Ag of the stamp body A. Switch array 26 including six detection switches 263 supported by switch holder 261
2 is provided. Each detection switch 263 includes a switch body 264 configured by a push switch or the like, and a switch top 265 whose tip faces the inside of the pocket 6. The switch top 265 has a flat plate portion 266.
And a detection protruding portion 267 extending at a right angle from the flat plate portion 266.
And the detection projection 267
And is guided in a guide hole 269 formed in the switch holder 261 to move in the front-rear direction.

The switch body 264 is fixed to the back surface of the substrate 270, and its plunger 271 is attached to the switch top 26.
5 so as to abut against the flat plate portion 266.
In this case, the plunger 271 urges the switch top 265 toward the pocket 6 by the spring force, and the tip of the detection protrusion 267 projects from the guide hole 269 of the switch holder 261 into the pocket 6 by this urging. And the state of being immersed in the guide hole 269 against this bias corresponds to ON-OFF of the detection switch 263.

On the other hand, the flat plate portion 26 of the switch holder 261
6 includes a switch operating portion 13 of the lid open link 62a.
2 are pressed against the spring force of the plunger 271, and all the switch tops 265 move in the front-rear direction with the rotation of the lid open link 62 a. Note that the switch operation part 132 and the switch top 265 may be formed integrally, or the switch top 265 and the detection switch 263 may be formed integrally, and the substrate 270 may be moved by the switch operation part 132. .

As described above, when the lid open link 62a rotates clockwise in the figure and the lid 7 is opened, the switch top 265 moves forward (toward the substrate 270), and the detection protrusion 267 is moved. Retreat from inside the pocket 6 (see FIG. 26). As a result, the detection mode of the detection device 66 is released, and the seal main body A can be attached and detached without interfering with the detection protrusion 267. On the other hand, the lid open link 62a rotates counterclockwise in the
Is closed, the switch top 265 moves rearward (toward the pocket 6), and its detection protrusion 267 projects into the pocket 6. As a result, the detection device 66 is set in the detection mode.
Is mounted, the switch top 265 comes into contact with the switch top 265, and the detection switch 263 is turned off to detect that the stamp body A is mounted (FIG. 2).
9). Conversely, when the stamp main body A is not mounted, the switch top 265 is in a state of protruding to the maximum, the detection switch 263 is turned on, and it is detected that the seal main body A is not mounted.

Actually, when any one of the detection switches 263 in the switch array 262 is turned off, it is detected that the stamp body A is mounted, and all the detection switches 263 are turned off. , It is detected that the stamp body A is not mounted. Note that, instead of the mode switching of the detection mode, FIG.
The detection projection 267 of the switch top 265 may be retracted from the inside of the pocket 6 to detect that the opening / closing lid 7 has been opened, and this may be used as a priority detection signal for preventing exposure.

Each detection switch 263 of the switch array 262 is turned on or off as shown in FIG. 29 or FIG. 30, depending on the presence or absence of the small hole Ah of the corresponding stamp body A. Therefore, the type of the stamp body A is determined based on the ON / OFF patterns of the six detection switches 263.

FIG. 31 shows the relationship between the small holes Ah of the stamp body A and the six detection switches (detection projections) 263. From the relationship between the six detection switches 263 and the presence / absence of the small hole Ah, 2 ⁿ −1 types, that is, 63 types of determination patterns are possible. In this case, there is no small hole Ah for the two detection switches 263 and 263 at both outer ends of the narrow stamp body A such as a square mark, and these two detection switches 263 and 263 are not used. It protrudes toward the space on both sides of the main body A. That is, in the case of a narrow stamp body A such as a square mark, an imaginary small hole Ah is formed at the outermost end of the stamp body A.
Is recognized as a discrimination pattern having.

In other words, the number of the discrimination patterns is reduced by allocating the discrimination pattern having the small hole Ah at the outermost end of the 63 kinds of the discrimination patterns to the narrow stamp body A such as a square mark. Without detecting all the detection switches 26
The stamp body A having a width that cannot be accommodated by the stamp body 3 can be determined. Note that the six detection switches 263 include a spare, and in practice, the four detection switches 26
3 is enough.

Next, a dial input device 68 comprising the operation dial 23 and its internal mechanism will be described with reference to FIGS. 34 and 35. As shown in both figures, the operation dial 23 is provided with an execution key 3 arranged circularly at the center.
1, a cursor / conversion key 32 divided into four parts arranged in a ring outside the character, and a character input key 33 further arranged in a ring outside the part. The execution key 31
The key also serves as a decision key and a line feed key for the input character. The cursor / conversion key 32 is a conversion key 32 on the near side.
a, a non-conversion key 32b on the side of the triangular mark 25, an uppercase / lowercase selection key 32c on the left side, and a hiragana / katakana / alphabet selection key 32d on the right side, which also serve as front, rear, left and right cursor keys. Characters indicating the respective functions are printed on the surfaces of these various keys.

The character input key (dial) 33 is configured to be rotatable forward and backward, and the rotation is a click rotation divided into 54 in the circumferential direction. On the surface of the character input key 33, a character 33a composed of Japanese syllabary and punctuation is assigned (printed) so as to correspond to the 54 divisions. A character 33a composed of a comma or the like is allocated (printed).

To input a seal character, first, a predetermined button 22a of the push button group 22 is pressed to specify the type of the seal body A. Next, the character input key 33 is rotated, a predetermined character is aligned with the triangular mark 25, and the enter key 31 is pressed to input a character.
Conversion is performed using the conversion key 32. Then, when the desired seal character is created on the display 24, the enter key 31 is again displayed.
Press to confirm this.

FIG. 36 shows a cross-sectional structure of the operation dial 23. As shown in FIG. 36, the execution key 31, the cursor / conversion key 32, and the character input key 33 are formed of different members. The execution key 31 and the cursor / conversion key 32 are supported by a key frame 282 extending from the substrate 281 so as to be freely pushable, and the character input keys 33 are rotatably supported by the apparatus case (support member) 2.
Thereby, the execution key 31 and the cursor / conversion key 3
2 has a structure that does not rotate with the rotation of the character input key 33. Therefore, when the character input key 33 is operated, the execution key 31 and the cursor / conversion key 32 are simultaneously rotated, so that there is no uncomfortable feeling that the character printed on the surface is rotated.

Next, a click mechanism for clicking and rotating the character input key 33 will be described. As shown in FIG. 37, the click mechanism includes a wavy surface portion 283 formed on the lower surface of the character input key 33, a click ball 284 that engages with the wavy surface portion 283, and a click ball 284 formed on the device case 2 that can be freely retracted. Ball groove 285 to be stored in
And a ball groove 285 to urge the click ball 284.
And a coil spring 286 provided in the main body. The wavy surface portion 283 is formed of 54 continuous concave and convex portions formed in a ring shape in the circumferential direction of the character input key 33. The click ball 284 is urged upward by the coil spring 286 and is engaged with the wavy surface portion 283.

When the character input key 33 is rotated, the click ball 284 successively engages with the concave position while climbing over the convex portion of the wavy surface portion 283, and intermittent rotation in which one rotation is divided into 54, that is, click rotation is performed. Done. As described above, since the click rotation is performed by the engagement between the wavy surface portion 283 of the character input key 33 and the click ball 284, the click ball 284 is appropriately rotated by the friction generated between the wavy surface portion 284 and the click ball 284. . Therefore, the sliding resistance associated with the rotation of the character input key 33 is reduced, and the stop position is stabilized. Therefore, the operation is performed smoothly and disciplined, and the operation feeling is improved. Further, since the wear between the wavy surface portion 283 and the click ball 284 can be minimized, the durability of this portion can be improved. Further, the coil spring 28
6, the urging force can be easily adjusted, and the adjustment of lightness and weight in the operational feeling can be easily performed.

Next, the input structure of the character 33a will be described with reference to FIG. This input structure is composed of brushes and contacts, and the figure shows the relationship between the brushes provided on the character input key 33 side and the contacts provided on the substrate 281 side. Inside the character input key 33,
Two rows of the first contact members 291,
291 and a character input key 3 inside the first contact member 291
3 and a row of second contact members 292 arranged concentrically. Each first contact member 291 has two divided portions 291a and 291a in the circumferential direction.
In 1a, conductive / non-conductive portions serving as ON-OFF elements are mixed. Also, the second contact member 292 is
Divided portions 292a, 292a, 292a, 292a
, And each of the divided portions 292a includes only a conductive portion that is an ON element.

On the other hand, a total of four first contact brushes 293 and 2 are provided at point-symmetrical positions at an angle of 180 degrees corresponding to the divided portions 291a of the two rows of first contact members 291 respectively.
93, 293 and 293 are provided. Also, one second contact brush 2 corresponding to one row of second contact members 292
The second contact brush 294 is provided next to one of the two first contact brushes 293 and 293. Thus, when the character input key 33 is rotated forward or backward, these four first contact brushes 293 are in sliding contact with the four divided portions 291a of the first contact member 291 respectively.
In addition, one second contact brush 294 is used for the second contact member 29.
2 is in sliding contact.

The ON-OFF relationship between the contact brushes 293 and 294 and the contact members 291 and 292 is as follows.
FIG. 39 shows a pattern represented by “1” and “0”. As shown in FIG. 38, the four divided portions 291a of the first contact member 291 correspond to the bits from “NO1” to “NO4” in FIG. Correspond to bits from “NO5” to “NO8”. For example,
The divided portion 291a corresponding to “NO5” is the contact brush 2
94, the ON state, that is, when the bit of “NO5” is “1”, the ON-OFF state of the divided part 292a corresponding to “NO1” to “NO4”, that is, from “NO1” "1"-"NO4" bit
According to the “0” pattern, the character whose “NO5” bit in FIG. 39 is “1”, that is, any one of the characters “A” to “S” is determined. Similarly, when the divided part 291a corresponding to “NO6”, “NO7” or “NO8” is ON, “SO” to “SO”
Any one of the characters “HI”, “F” to “R”, or “RE” to “SP” is determined based on the patterns “NO1” to “NO4”.

In this case, for one rotation of the character input key 33, four divided portions 291a of the first contact member 291 are provided.
And 4 corresponding first contact brushes 293, 2 ⁴ = 16 bit patterns are obtained, and the four divided portions 29 of the second contact member 292 are obtained.
Since four classification patterns are obtained by the combination of 2a and the second contact brush 294, 16 × 4 = 64 discrimination patterns are obtained by these combinations. However, in this case, character 3 is used by using 54 of the 64 characters.
3a.

As described above, since the discrimination pattern is formed by the combination of the bit pattern and the classification pattern, a plurality of first contact brushes 293 correspond to each first contact member 291 constituting the bit pattern. Can be done. That is, each first contact member 291 is divided into a plurality of parts in the circumferential direction (divided portions 291a), and the first contact brushes 293 can be disposed on the respective first contact members 291. The first contact members 291 in each row can be used. A plurality of bit patterns can be configured. Therefore, it is not necessary to increase the number of rows of the first contact members 291 in order to obtain a desired number of bit patterns, and as a result, the character input keys 33 can be made relatively small. That is, the diameter and width of the character input keys 33 can be set to give priority to operability.

Next, another embodiment of the input structure of the character 33a will be described with reference to FIG. 40 and FIG. This input structure is basically the same as the input structure described above with reference to FIGS. 38 and 39, except that the second contact member 292 is divided into six in the circumferential direction. First contact member 291 and second contact member 292
Is different from the arrangement position of the conducting / non-conducting portion. These differences are caused by an unstable state that may occur in a character discriminating circuit or the like when the input structure of FIGS. 40 and 41 is changed by rotating the dial between adjacent characters, a so-called “hazard”. This is because a discrimination pattern having a larger number of bits is used to avoid the above problem.

Here, the discrimination code and the hamming distance used in the following description to help understand the present example will be described. FIG. 41 shows each of the contact brushes 293 and 294 and each of the contact members 291 and 29 in FIG.
41. The ON-OFF relationship of No. 2 is represented by patterning with “1” and “0”. The four divided portions 291a of the first contact member 291 in FIG.
The bits correspond to bits from “1” to “NO4”, and the six divisions 292a of the second contact member 292 are “N
It corresponds to bits from "O5" to "NO10".
A code in which the bits from "NO1" to "NO10" are arranged is hereinafter abbreviated as "determination code". For example, when the determination code of the character "?" In FIG. CA = “?” = [110
0100000]. Similarly, for the adjacent character “ki”, the discrimination code CB = “ki” = [1
00000000], the bit of which the value of the corresponding bit of the discrimination code CA differs from that of the discrimination code CB is only one bit of “NO2”. The Hamming distance H to the CB is represented by H (CA, CB) = 1.

Next, the possibility of erroneous character discrimination when the dial is rotated between adjacent characters and changed is described. For example, as shown in FIG. 41, when the discrimination code CC = “ku” = [100001000000], the hamming distance H (C
B, CC) = 2. In this case, when the dial is rotated from the character “K” to “K” or from the character “K” to “K”, which bit of “NO5” or “NO6” changes first? In other words, depending on the variation of the threshold value and delay time of the element such as the determination circuit
In the transient state, the discrimination code CD = [100011000]
0] or discrimination code CE = [1000000000000]
There is a possibility of the state. If characters corresponding to these discrimination codes CD or CE exist,
The character discriminating circuit or the like may erroneously discriminate the transient discrimination code CD or CE, and as a result, the dial input device 68 may malfunction.

On the other hand, in the input structure shown in FIGS. 40 and 41, the same divided portion 291a of the second contact member 292 is provided.
, For example, the characters "A" to "K" whose bit of "NO5" is 1 have the discrimination codes of the adjacent characters, for example, the discrimination codes CA and CB of "K" and "K" described above. Hamming distance H = 1
Therefore, other characters are not transiently determined. In addition, the adjacent divided part 291a
In between, for example, the hamming distance H = 2, such as the above-described determination codes CB and CC of “ki” and “ku”, and a determination code that may occur transiently during that, For example, since the above-described discrimination codes CD and CE are empty discrimination codes that do not correspond to any of the characters, similarly, other characters are not transiently discriminated. Therefore, with this input structure, a hazard can be avoided, and erroneous determination and malfunction due to the hazard can be prevented.

Note that any of the character discrimination codes is determined by contact brushes 293 and 294, contact members 291,
If the user wants to change the mechanical strength in order to reinforce the mechanical strength of 292, for example,
The bit of “NO4” is set to “1” and the discrimination code CF
In the case where it is desired to change "=" to "10011100000", the following examination is performed. Discrimination code CF =
[K] and one adjacent discrimination code CA = “?” =
Hamming distance H (CA,
CF) = 2, the transient discrimination code is discrimination code CG =
[1101110000] and the discrimination code CH = [100
0100000], and a hamming distance H (CC, CF) = 3 from the other adjacent discrimination code CC = “ku” = [100001000000], and a transient discrimination code C
I = [10001000000], CJ = [100100
0000], CK = [1001110000], CL =
[1000000000000], CM = [100001100]
00] and CN = [1001010000]
Individual. Of these, the discrimination code CN is equivalent to the discrimination code of "ke". Therefore, if the dial is rotated from "ki" to "ku" or "ku" to "ki", "ke" is misunderstood. May be different.

In this case, if the discrimination code of "ke" is set as the discrimination code CP = "ke" = [10100100000], the hamming distance H = 1 between the adjacent discrimination codes of "ku" and "ko" is maintained. In addition, the determination code CB of "" can be changed to the determination code CF, and the transient determination code C
Everything such as N becomes a blank discrimination code, and a hazard can be avoided, and erroneous discrimination of a character can be prevented.

That is, if the discrimination code of each character is determined in consideration of the hamming distance of the discrimination code of an adjacent character, any one of the characters (in the above case, “ki”) Hamming distance between the discrimination code (CF) and the discrimination code (CC) of a character ("ku") adjacent thereto is H ≧ 2 (H =
In the case of 3), among H (= 3) bits (“NO4”, “NO5”, “NO6”) having different values, G (G = 1, 2,..., H−1): In the above case, 1,
2) 2 ^H −2 (2 ³ −2 = 6) with inverted bits
Identification codes (one inverted: CI, CJ, CK, and two inverted: CL, CM, CN) can be null identification codes that do not correspond to any of the characters. It is possible to avoid a hazard that may occur at the same time, and prevent occurrence of erroneous determination of a character and the like. As a result, malfunction of the dial input device can be prevented.

In the above-described embodiments of FIGS. 38 to 41, the brush is provided on the character input key side and the contact is provided on the substrate side. Conversely, the contact is provided on the character input key side and the brush is provided on the substrate side. You may do so. Further, the dial input device of the present invention is also applicable as an input device of another electronic device. In this case, the number of rows and the number of divided portions of the first contact member, and the number of divided portions of the second contact member It is needless to say that is determined by the number of necessary determination patterns.

As described above, according to the dial input device of the present invention, since the push button does not rotate in accordance with the dial operation, the operation does not feel uncomfortable and erroneous operation can be prevented.
