Even if the access target has an abutting surface such that the abutment of some of the switches is removed by allocating it to the object, it can be discriminated without reducing the total number of discrimination patterns. This means that it is possible to discriminate an access target having an abutting surface smaller than the area where the n switches are arranged, and conversely, it is possible to make the area where the switches are arranged large. Furthermore, if any one of the switches is operated with the type detection hole “absent”, the presence of the access target itself can be detected.

In the access object detecting apparatus for an electronic device of the present invention, it is preferable that the electronic device is an exposure device and the access object is a stamp main body on which a stamp surface is formed by exposure of the exposure device.

According to this structure, it is possible to detect the type of the stamp main body having various shapes and also detect that the seal main body is mounted in the pocket. At that time, it is possible to reliably detect various stamp main bodies mounted on the exposure apparatus so that the center of the stamp surface is located at the same position.

By exposing the portion of the ultraviolet curable resin (print surface Ad) of the stamp main body A to ultraviolet light using the ink ribbon C as a mask, the portion of the stamp surface Ad corresponding to the stamp character is cured. Seal body A in this state
Is taken out from the pocket 6 and washed to wash out the water-soluble uncured portion to complete the stamp. Reference numeral Ae in the drawing is a resin cap. Note that an ultraviolet softening resin may be used instead of the above ultraviolet curable resin, and in such a case, if the positive and negative of the ink ribbon C and the plate making sheet B are reversed, the same seal as that of the embodiment can be created. You can

As shown in FIG. 2, in this seal making apparatus 1, the ink ribbon C wound around the unwinding reel 13 is guided to the printing portion via the first path pin 51, and further the second path pin. It is guided to the exposure section via 52 and the first guide pin 53, and is taken up from the exposure section on the take-up reel 14 via the second guide pin 54 and the tension pin 55. In the printing section, the print head 56 and the platen roller 57, which are arranged so as to sandwich the ink ribbon C, perform printing while pushing the ink ribbon C.
In the exposure section, the ink ribbon C is sandwiched between the stamp main body A and the stamp main body A by the pressing plate 58, and the seal main body A is exposed to ultraviolet light.

As shown in FIG. 3, the mechanical device section 4 has a built-in ribbon feeding device 61 for rotating the take-up reel 13 and the platen roller 57 to run the ink ribbon C. Further, as shown in FIG. 4, in the mechanical device section 4, a lid open link 62a for locking / unlocking the opening / closing lid 7, a head moving link 62b for separating / contacting the print head 56 of the printing section from the platen roller 57, A ribbon pressing link 62c for moving the pressing plate 58 of the exposure section forward and backward,
The lid open link 62a and the head moving link 62
A function link mechanism 62 including b and a main link 62d for operating the ribbon pressing link 62c is built in.

First, the ribbon feeding device 61 will be described in detail with reference to FIG. Ribbon feeding device 61
Is a drive motor 10 built in below 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.
It is designed to rotate 03 and. 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. Then, from the main gear 107, one is a reel reduction gear train 108.
To the reel shaft 102, and the other roller reduction gear train 1
Power is transmitted to the roller shaft 103 via 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 the output shaft 1
The power transmission gear 106 meshes with the main gear 107 so that the power transmission gear 106 can freely come into contact with and disengage from the main gear 107 in association with the rotation of 04.
That is, when the drive motor 101 rotates, the clutch arm 110 rotates, and the power transmission gear 106 becomes the main gear 10.
7, the power of the drive motor 101 is transmitted to the take-up reel 13 and the platen roller 57. vice versa,
If 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 mesh. Thus, for example, when the erroneously inserted plate-making sheet B is pulled out, the platen roller 57 easily rotates (reverses) without receiving the load of the drive motor 101, and does not affect the ink ribbon C. Only B can be pulled out easily. However, the clutch arm 110 may be rotated in association with the switching of the function switch 8. The reel shaft 102 is a sliding shaft and absorbs a change in peripheral speed that increases as the ink ribbon C is wound around the take-up reel 13 by causing slippage.

And a pair of hook portions 130, 130 extending from both ends of the open link body 128 toward the opening / closing lid 7, and a lever portion 131 extending downward from the open link body 128 so as to correspond to the tongue piece of the main link 62d. And a switch actuating portion 132 that is bent forward from the open link body 128 and extends (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 biased 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.

Turn the function switch 8 from the "OFF" position to the "O" position.
Rotated to the "PEN" position, the tongue 1 of the main link 62d
25 rotates forward and pushes the lever portion 131 of the lid open link 62a against the coil spring 133, and the hook portion 1
The hooking of 30 to the hook receiving portion 7a is released.
On the other hand, a leaf spring 7b for stably pressing the stamp body A housed in the pocket 6 is attached to the back surface of the opening / closing lid 7, and when the hook portion 130 is removed, the opening / closing lid 7 is housed in the pocket 6. When receiving the stamp main body A, it is flipped up (see FIGS. 5 and 8). Even when the stamp body A is not accommodated in the pocket 6, the opening / closing lid 7 is flipped up by the lock member 171 of the lock mechanism 63 described later by "OPEN" of the function switch 8 (see FIG. 10).

Further, by releasing the hooking of the lid open link 62a, the switch operating portion 132 causes the detecting end of the detecting device 66, which will be described later, to project into the pocket 6. When the function switch 8 rotated to the "OPEN" position is released, the coil spring 133 causes the function switch 8 to move through the lid open link 62a and the main link 62d.

An engaging 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 stretched between the frame 121 and the engaging surface 136. The coil spring 137 urges the tip of the head movement link 62b to rotate about the support shaft 135 toward the platen roller 57, and also urges the engagement surface 136 to press against the first pin 126. . The engaging surface 136 has a first stationary surface 139 on the tip end side and a second stationary surface 140 on the tail end side which are arcs concentric with the support shaft 124 of the main link 62d with the inclined surface 138 interposed therebetween. When 62d is rotated and its first pin 126 is in contact with the second stationary surface 140, the print head 56 is separated from the platen roller 57 and is in contact with the first stationary surface 139. The print head 56 contacts the platen roller 57. When the ribbon cartridge 11 is attached and detached, a jig (not shown) is used to largely rotate the print head 56 in a direction in which it is further separated from the platen roller 57.

As shown in FIG. 6, the function switch 8 is set to "O".
When 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, and the coil spring 137 causes the head to move. The moving link 62b rotates, and the print head 56 is pressed against the platen roller 57. On the contrary, when the function switch 8 is rotated from the “input / plate-making” position to the “OFF” position, the first pin 126 moves the first pin 126 to the first position.
The second stationary surface 14 goes up from the stationary surface 139 to the inclined surface 138.
The head moving link 62b rotates against the coil spring 137 and the print head 56 separates from the platen roller 57.

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

The ribbon pressing link 62c is formed in a substantially "T" shape as a whole, and the guide grooves 142 formed at the left and right end portions and the front end portion are formed in the frame 12 respectively.
The three projections 143 that are erected at 1 are engaged with each other, and are attached to the frame 121 so as to be able to move back and forth in a slightly floating state. Each guide groove 142 is formed in a keyhole shape, while a disc-shaped retaining portion is formed on the upper end of the protrusion 143 (not shown), and the ribbon pressing link 62c has a circular portion of the guide groove 142. The frame 121 is attached to the frame 121 by being aligned with the retaining portion and pushed in, and is guided forward and backward by the protrusion 143 in the long hole portion of the guide groove 142. Further, two support pins 144 and 144 are provided at both ends of the ribbon pressing link 62c that has escaped from the guide groove 142.

Also, due to this rotation, the other end of the notch of the lower cam portion 150 is moved to the second pin 12
It rotates to a position where it almost comes into contact with 7 (see FIG. 7).

The guide groove 142 also serves as a stopper for restricting the forward end position of the ribbon pressing link 62c, and the end of the long hole portion of each guide groove 142 has the protrusion 14 at its end.
When it hits against 3, the ribbon pressing link 62c stops at the forward end position. Therefore, the above-mentioned upper cam portion 1
In the state where the engaging portion 147 of the ribbon pressing link 62c is in full contact with the chord portion of 49, the urging force of the coil spring 146 does not actually act on this portion, and the engaging portion 147 is in effect. The contact surface of 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 through the "input / platemaking" position to the "OFF" position, the second pin 127 pushes the other end of the notch of the lower cam portion 150, The ribbon pressing cam 122 is rotated clockwise. By this rotation, the engaging portion 147 of the ribbon pressing link 62c is relatively returned from the chord portion of the upper cam portion 149 to the peripheral end portion, and the ribbon pressing link 62c is rotated by the coil spring 1.
Retreat against 46. In this state, the coil spring 14
The freely rotatable ribbon pressing cam 122 is stretched against the ribbon pressing link 62c urged by 6, and the ribbon pressing link 62c is maintained in 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 portion 150, with which the second pin 127 is in contact, moves to the second position.
Since the pin 127 is substantially parallel to the moving direction of the pin 127, the ribbon pressing cam 122 is slightly rotated clockwise, and the ribbon pressing link 62c is maintained in the retracted position (see FIG. 5).

In this way, the function switch 8 is turned off.
From the position to the "OPEN" position, hook 1
30 is disengaged, and the opening / closing lid 7 becomes openable.
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 enable printing, 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 to be in a state where it can be exposed. If the opening / closing lid 7 is accidentally opened during exposure, or if exposure is performed with the opening / closing lid 7 open, ultraviolet rays leak to the outside, which is not preferable. Also, when printing, the opening / closing lid 7
Opening it may cause jamming of the ink ribbon C.
Therefore, in the embodiment, the lock mechanism 63 locks the opening / closing lid 7 in the closed state during the printing operation and the exposing operation, and prevents the printing operation and the exposing operation from moving when the opening / closing lid 7 is open. 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 ease of understanding. As shown in FIG. 9, the function switch 8 has a mark 16 for indicating the set position on the upper surface.
2 is provided with a dial 161, a click member 163 attached to the inner space of the dial 161, and an eccentric pin 123 that engages with the main link 62d. It is rotatably attached to the seat plate portion 2a of the case 2. The click member 163 is curved and extends in the radial direction of the dial 161.
A pair of click arms 165, 165 located in point symmetry
Due to the spring property of each click arm 165, the circular portion 165a at the tip thereof is pressed against each click engaging portion 166 formed on the seat plate portion 2a.

Each click engaging portion 166 has four convex portions 166a and three concave portions 166b toward the click arm.
When the circular portion 165a of each click arm 165 is depressed (engaged) in the three concave portions 166b, the above-mentioned "OFF" position, "input / plate-making" position, and "exposure" It corresponds to the position (see FIG. 9A). Further, the middle position of the convex portion at the outermost end corresponds to the “OPEN” position, and click-like engagement is not 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. In addition, "OFF" position and "OPE
There is a rotation angle of 15 degrees with the “N” position.
There are rotation angles of 30 degrees between the "FF" position, the "print" position, and the "exposure" position.

On the other hand, as shown in FIGS. 10 and 11, the lock mechanism 63 includes a lock member 171 provided at the boundary between the function switch 8 and the pocket 6, and the lock member 1
71 is attached to the seat plate portion 2a of the device case 2 so as to be vertically movable while being biased upward by the lock spring 172. The lock member 171 includes a member main body 173 guided by the seat plate portion 2 a so as to be vertically movable, a push arm portion 174 extending from the member main body 173 to the pocket 6 side and bending and extending upward, and the member main body 173 to the function switch 8. And a lock arm portion 175 that extends to the side and bends and extends upward.

The push arm portion 174 faces the lid seating portion 6a of the pocket 6 from the lower side. When the opening / closing lid 7 is opened, the push arm portion 174 projects from the lid seating portion 6a, and when closed, the push arm portion 174 is pushed into the lid seating portion 6a. That is, when the opening / closing lid 7 is opened, the lock member 171 is moved upward by the lock spring 172, and when 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 to prevent the function switch 8 from rotating. On the contrary, when the lock member 171 is moved 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, and when the function switch 8 is rotated between the "OFF" position and the "OPEN" position (normally, this operation is not performed. ) Is allowed to rotate. On the contrary, 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 opening / closing lid 7 is opened, the function switch 8 is prevented from rotating, and the printing operation and the exposure operation cannot be performed.

The mechanism for locking the opening / closing lid 7 in the closed state during the printing operation and the exposure operation is the main link 6 described above.
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 62a
Thus, the opening / closing lid 7 is closed and locked. As a result, exposure is not performed while the opening / closing lid 7 is open, and the opening / closing lid 7 is not opened while exposure is being performed.

Next, the printing device 64 provided in the printing unit will be described with reference to FIG. As described above, the printing device 64 includes the print head 56 that prints a stamp character on the ink ribbon C, and the platen roller 57 that sends the ink ribbon C in response to the printing operation of the print head 56.
Further, toward the contact portion between the print head 56 and the platen roller 57, the apparatus case 2 is formed with a feed passage 181 into which the plate-making sheet B is fed and a feed passage 182 from which the plate-making sheet B is fed. ing. The outlet 9a opened to the outside is formed at the upstream end of the delivery passage 181, and the outlet 9b opened to the outside is formed at the downstream end of the delivery passage 182.

The platen roller 57 is a drive roller as described above, and the ink ribbon C is unwound from the unwind reel 14, and the plate making sheet B is gripped between the print head 56 and the ink ribbon C and the plate making roller 57. The sheet B and the sheet B are overlapped and face the print head 56. Print head 5
A thermal head 6 transfers the ink applied to the ribbon tape of the ink ribbon C to the plate making sheet B by thermal transfer. By this transfer, the portion corresponding to the stamp character is peeled off from the ink ribbon C, and the background of the transparent ribbon tape appears on that portion, while the peeled ink adheres to the plate-making sheet B as the stamp character.

A sensor 183 for detecting the insertion and the feed reference position of the plate-making sheet B faces the feeding path 181, and the plate-making sheet B inserted in the feeding path 181 is exposed.
Is sent by the platen roller 57 according to 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 portion 184 is formed at the tip (upstream end) of the left wall of the delivery passage 182, and the separation claw portion 184 sends the ink ribbon C and the plate-making process sent in a stacked state. The sheet B is separated. Then, the ink ribbon C is sent to the former exposure section, and the plate-making sheet B is sent to the outside of the apparatus through the sending passage 182.

Next, with reference to FIGS. 13 and 14, an exposure device 65 provided in the exposure unit will be described. The exposure device 65 is a stamp surface Ad of the stamp main body A set in the pocket 6.
It is provided with an ultraviolet light source 191 provided so as to face each other, and a holding plate 58 provided between the ultraviolet light source 191 and the stamp surface Ad of the stamp main body A. Stamp body Ad of stamp body A and pressing plate 5
8 and the ultraviolet light source 191 are arranged in parallel with each other with a gap therebetween, and the ink ribbon C is arranged between the printing surface Ad and the pressing plate 58. The pressing plate 58 is made of a transparent resin or the like, and moves forward to press the ink ribbon C against the printing surface Ad of the stamp main body A.
That is, at the time of exposure, the stamp body A is pressed by the pressing plate 58.
After the ink ribbon C is pressed against the print surface Ad of the ink ribbon Ad, the ultraviolet light source 191 is turned on, and the ink ribbon C is pushed over the holding plate 58.
Is used as a mask (see FIG. 13).

The ultraviolet light source 191 is a self-heating type 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 temperature fuses 194 and 194 for detecting the life and failure of the ultraviolet light source 191 are provided at the left and right ends of the. Each of the temperature fuses 194 is formed in a cylindrical shape, and is provided so as to contact the ultraviolet light source 191 from below in a direction orthogonal to the longitudinal direction of the ultraviolet light source 191. Each thermal fuse 194 has a holding arm 1 extending from the fluorescent tube holder 193.
It is held from below by 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 reflecting plate behind the ultraviolet light source 191 to irradiate the ultraviolet light in a concentrated manner 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 is not conducted to the thermal fuse 194. In such a case, the rising of the light amount of the ultraviolet light source 191 becomes good.

The holding plate 58, as shown in FIGS. 17 and 18, is made of a transparent resin or the like formed in a rectangular shape.
Left and right pressing plate holders 201, 201 at both ends in the longitudinal direction
Attached to. In addition, each holding plate holder 201
Are attached so as to be inserted into the two support pins 144 and 144 provided upright at each end of the ribbon pressing link 62c (see FIG. 14). The holding plate 58 is a holding plate body 202 that is pressed against the stamp surface Ad of the stamp body A.
And 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 to the side opposite to the stamp body A in the longitudinal direction, that is, to the ultraviolet light source side, and when the ink ribbon C is pressed against the stamp surface Ad of the stamp body A by the pressing plate 58, On the other hand, the ink ribbon C can be pushed out. Further, 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. As a result, when the ribbon cartridge 11 is mounted, the ink ribbon C is properly guided between the pressing plate 58 and the stamp body A. Further, both ends of the pressing plate body 202 are chamfered in an arc shape, and the ink ribbon C is bent at the chamfered portion 207 at the time of exposure so as not to cause wrinkles (see FIG. 13). Note that 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 pressing plate holder 201 is formed with a pair of upper and lower V-grooves 210, 210 for guiding the pair of upper and lower guide claws 203, 203 of the pressing plate 58 in the front-rear direction, and the shaft projection 205 in the front-rear direction. Groove 2 for rotatably guiding
11 is formed. That is, the pressing plate 58 has the guide claw 203 in the V groove 210 and the shaft projection 205 at both ends thereof.
Are attached to the left and right pressing plate holders 201, 201 so as to be engaged with the recessed grooves 211, respectively, so as to be movable back and forth by a minute distance and swingable in the front and rear directions.
Further, in this state, a pair of upper and lower spring pieces 21 extending from the respective holding plate holders 201 are provided at the outer end portions of the holding plate 58.
2, 212 are pressed from the rear side, and the pressing plate 5
8 is urged by the spring piece 212 toward the forward end position where the claw portion of the guide claw 203 contacts the groove bottom portion of the V groove 210.

When the ribbon pressing link 62c moves forward from the state shown in FIG. 14 (FIG. 2), the pressing plate holders 201, 201 move forward accordingly, and the pressing plate 58 faces the stamp surface Ad of the stamp main body A. Move in parallel. The moving stroke of the ribbon pressing link 62c is slightly longer than the distance between the pressing plate 58 and the stamp surface Ad of the stamp main body A,
When the ribbon pressing link 62c reaches the forward position,
The pressing plate 58 and the stamp surface Ad of the stamp main body A have already abutted against each other, and the pressing plate 58 receives a reaction force from the stamp surface Ad, and slightly retracts relative to each pressing plate holder 201. Since the retreat of the pressing plate 58 is due to the reaction force from the stamp surface Ad, the reaction force opposes the pressing force of each part of the pressing plate 58, and the pressing plate 5
8 abuts on the stamp surface Ad of the stamp main body A (see FIG. 13).
reference). In other words, the holding plate 58 holds the ink ribbon C, and brings it into close contact with the printing surface Ad of the stamp main body A without any gap.

Further, as shown in FIG. 18, each holding plate holder 201 is integrally formed 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 shape in cross section, and is arranged with its arc surface facing the holding plate 58 side. A pair of left and right support pieces 216 each having a circular hole are formed in the upper and lower intermediate portions of the ribbon sliding contact member 215, and the circular hole of the support piece 216 is used for the guide pin holding portion 21.
The ribbon sliding contact member 215 is attached to the pair of shaft projections 217 formed in FIG. 4 from the outside so as to be swingable in the rotational direction with respect to the shaft of the guide pin holding portion 214.

The guide pin holding portion 214 and the ribbon sliding contact member 215 are arranged outside the pressing plate 58 and the stamp main 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 above-mentioned first guide pin 53, and the left guide pin holding portion 214 and the ribbon sliding contact member 215 constitute the above-mentioned second guide pin 54. That is, the first guide pin 53 and the second guide pin 54
As a result, the ink ribbon C running between the pressing plate 58 and the stamp surface Ad of the stamp main body A does not interfere with these,
It is designed to be guided in parallel with these.

As will be described later in detail, since the guide pin holding portion 214 constitutes a part of the pressing plate holder 201, the first guide pin is moved along with the forward movement of the pressing plate (ribbon pressing link 62c) 58. 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 reduced in its tension, that is, in the state where vertical wrinkles do not occur. It is pressed against the stamp surface Ad of the stamp body A.

This state will be described in more detail with reference to FIGS. 2 and 13. The ink ribbon C running in FIG.
On the other hand, a strong tension acts on the take-up reel 13, and as described above, the ink ribbon C has vertical wrinkles due to the extremely thin tape. Therefore, if the ink ribbon C is pressed against the stamp surface Ad of the stamp main body A as it is, the ink ribbon C is pressed against the stamp surface Ad with vertical wrinkles, and the stamp characters are distorted and exposed. On the other hand, when the ink ribbon C is loosened, the stamp characters are displaced and exposed. Therefore,
As shown in FIG. 13, as the pressing plate 58 moves forward, 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 that time, the tension pin 55 applies tension to the ink ribbon C with a weak force that does not cause vertical wrinkles. ing.

The ink ribbon C in the exposed state of FIG. 13 has the tension pin 55 and the second path pin 52.
Thus, the ink ribbon C is bent backward at both ends of the pressing plate 58, and the chamfered portions 207 formed at both ends of the pressing plate 58 prevent unnecessary wrinkles from occurring on the ink ribbon C.

Now, with reference to FIG. 19, the path of the ink ribbon C will be described. The ink ribbon C wound from the unwinding reel 14 is appropriately guided to the printing device 64 by the first path pin 51, and further largely bent by the second path pin 52 from the printing device 64, and the subsequent first guide pin. It is properly guided to the exposure device 65 by the 53 and the second guide pin 54, and finally wound on the take-up reel 13 via the tension pin 55. This route is used when the ink ribbon C is running and when it is waiting to run,
As described above, the route at the time of exposure is different from this, and also when carrying it as the ribbon cartridge 11, it is different. Here, before describing the route when carrying the ribbon cartridge 11, 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 including 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 attached to the apparatus body 5 by fitting the legs 223 of the accommodation section 5a of the apparatus body 5 with the base plate 222 facing upward. The legs 223 are provided at each corner of the cartridge case 221 as shown in FIG.

At the end on the short side of the base plate 222, the take-up reel 14 is rotatably provided vertically.
A take-up reel 13 is rotatably provided at the end on the long side. Further, a first path pin 51 with a reinforcing rib that hangs from the base plate 222 is provided ahead of the unwinding reel 14, and a path changing member 224 that is configured to be movable back and forth in the front-back direction is provided further ahead thereof. Has been. In front of the take-up reel 13, the tension pin 55
Is provided on the base plate 222 so as to be movable back and forth while being biased by the coil spring 225. As shown in FIG. 20B, the reel shaft 1 of the unwinding and winding reels 13 and 14 is provided in the housing portion 5a of the apparatus body 5.
02, 226, print head 56, platen roller 57,

8, an ultraviolet light source 191 and the like are provided.

As shown in FIG. 21, the take-up reel (same as the take-up reel 13) 14 is provided with a cylindrical shaft portion 228 around which the ink ribbon C is wound, and an 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 upper engaging portion 229 is rotatably supported by the base plate 222, and the lower engaging portion 230 is provided. Is rotatably supported on the apparatus body 5 side. The upper engaging portion 229 includes a cylindrical portion 231 and a flange-shaped crown portion 232 that is continuous with the upper side of the cylindrical portion 231, and correspondingly, the base plate 222 has a bearing with which the cylindrical portion 231 is rotatably slidably contacted. A portion 233 and a step portion 234 on which the lower surface of the crown portion 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.
In the state in which is in contact with (engaged with) the stepped portion 234, the unwind reel 14 can rotate only in 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, the engagement between the crown portion 232 and the step portion 234 is released, and the unwinding reel 14 is It becomes rotatable. On the other hand, when the ribbon cartridge 11 is not attached to the apparatus main body 5, the unwinding reel 14 is pushed down by its own weight, the crown portion 232 and the step portion 234 are engaged with each other, and the unwinding reel 14 is not stopped. work. This reverse rotation stop prevents the ink ribbon C from slackening, and the take-up reel 13
The rotation of the unwind reel 14 is blocked in the direction opposite to the running direction of the ink ribbon C, and the winding reel 14 is blocked in the running direction of the ink ribbon C. Of course, take-up reel 13 and unwind reel 14
Both can rotate in the direction in which the ink ribbon C is stretched. The ribbon cartridge 11 provided for replacement has a crown portion 232 on the upper surface of the base plate 222.
A plate (not shown) to be pressed against 34 is provided, and in this state, it is packaged and raised.

The route changing member 224 is 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 changing pin 237 integrally formed in 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 changing pin 237 is attached to the slider 236.
When the slide reel moves in the front-rear direction and moves rearward to the maximum, the take-up reel 13 and the take-up reel 14
The ink ribbon C, which is stretched between and, is stretched at a substantially right angle. In this case, the ink ribbon C is stretched at a right angle until the ribbon cartridge 11 is attached to the apparatus main body 5, and when the ribbon cartridge 11 is attached to the apparatus main body 5, the path changing pin 237 is moved to the maximum forward. (See Figure 22).

As a result, when the ribbon cartridge 11 is mounted, the path changing pin 237 and the tension pin 5
5 cooperates with each other to regulate the path of the ink ribbon C so as not to interfere with the pressing plate 58, the stamp main body A, the second path pin 52, and the like, and the path changing pin 237 and the first path pin 51 cooperate with each other. It works to regulate the path of the ink ribbon C 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, by moving the path changing pin 237, the ink ribbon C
The route of becomes the state at the time of traveling and at the time of traveling standby described above.

The tension pin 55 includes a sliding contact portion 239 having a semicircular cross section and a support plate portion 2 supporting the sliding contact portion 239.
40, and the coil spring 225 interposed between the base plate 222 and the base plate 222 biases the ink ribbon C in the tension direction. The spring force of the coil spring 225 is so weak that the tensioned ink ribbon C does not have vertical wrinkles, and the tension pin 55 functions so that the ink ribbon C is not loosened. That is, in the ribbon cartridge 11 for replacement, as described above, the take-up reel 13
Further, the unwinding reel 14 is in the reverse rotation stop state, the ink ribbon C is stretched between the reels 13 and 14, and the tension pin 55 abutted against the ink ribbon C is an ink ribbon caused by vibration or the like. Prevent loosening of C.

In the exposure operation as described above, the holding plate 58 and the first and second guide pins 53 and 54 are
The tension pin 55 prevents the ink ribbon C from being loosened when the seal body A is moved forward simultaneously.
And stretch it to the extent that vertical wrinkles do not occur. If it is not necessary to request the former function of 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-height shape like a general pulley and lie in a horizontal plane. The ink ribbon C running in the closed state does not drop off from the sliding contact portions 239 and 242. Further, even if the sliding contact portions 239, 242 and the ink ribbon C are not exactly orthogonal to each other, it is possible to prevent problems such as the ink ribbon C running unevenly. That is, the ink ribbon C that comes into contact with the sliding contact portions 239 and 242 travels so that the intermediate portion in the width direction thereof is slightly raised. Thereby, the second
Each sliding contact portion 24 of the route pin 52 and the tension pin 55

Next, the detecting device 66 that interlocks with the opening / closing of the opening / closing lid 7 will be described. 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 available in various shapes such as square stamps, name stamps, business stamps, and address stamps. These stamp bodies A have the same length but the same width. And the thickness is different. In order to set such various stamp main 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 FIG. 24 and FIG. Bottom 6b of 6
Four long and short bosses 251, 251, 251, 251 are erected on the boss, and correspondingly, the stamp body A is formed with a fitting hole Af into which the boss 251 is fitted (see FIG. 32).

Four bosses 251, 251, 251 and 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 depth of the fitting holes Af of the seal main body A are different depending on the type of the seal main body A, and the combination of the fitting holes Af and the boss 251 allows various seals mounted in the pocket 6. The center of the stamp surface Ad of the main body A is positioned so that it is always at the same position.

The back surface A opposite to the stamp surface Ad of the stamp body A
In g, a plurality of sub-holes (type detection holes) are arranged laterally symmetrically at the center position, that is, at an intermediate position in the thickness direction.
Ah is formed, and the type of the stamp main body A is determined by cooperation with the switch array 262 of the detection device 66 described later (see FIG. 31). In addition, the back Ag of the stamp body A
A stamp character label Bd of the plate-making sheet B, which is separated from the ink ribbon C after printing and sent to the outside of the apparatus after printing, is attached to the cover, thereby hiding the small hole Ah.

As shown in FIGS. 26, 27 and 28, the detection device 66 includes a switch holder (which also serves as the wall surface of the pocket 6) 261 arranged so as to face the back surface Ag of the stamp main body A, A switch array 26 including six detection switches 263 supported by a switch holder 261.
2 is provided. Each detection switch 263 is composed of a switch main body 264 composed of a push switch and the like, and a switch top 265 whose tip faces the inside of the pocket 6. The switch top 265 is a flat plate portion 266.
And a detection protrusion 267 that extends at a right angle from the flat plate portion 266. The switch holder 261 is provided below the flat plate portion 266.
The guide protrusion 268 formed on the
Is guided by the guide hole 269 formed in the switch holder 261, and moves in the front-back direction.

The switch main body 264 is fixed to the back surface of the substrate 270, and the plunger 271 is attached to the switch top 26.
5 is arranged so as to abut against the flat plate portion 266.
In this case, the plunger 271 biases the switch top 265 toward the pocket 6 side by its spring force, and the bias causes the tip of the detection protrusion 267 to project from the guide hole 269 of the switch holder 261 into the pocket 6. The state in which the detection switch 263 is depressed into the guide hole 269 against the 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 is abutted against the spring force of the plunger 271 so that all the switch tops 265 move in the front-rear direction with the rotation of the lid open link 62a. Note that the switch operating unit 132 and the switch top 265 may be integrally formed, or the switch top 265 and the detection switch 263 may be integrally formed and the switch operating unit 132 may move the substrate 270. .

As described above, when the lid open link 62a is rotated clockwise in the drawing and the opening / closing lid 7 is open, the switch top 265 moves forward (to the side of the substrate 270), and the detection protrusion 267 of the switch top 265 moves. Withdraw from 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 is rotated counterclockwise in the drawing to open and close the lid 7.
When the switch is closed, the switch top 265 moves rearward (toward the pocket 6), and the detection protrusion 267 thereof projects into the pocket 6. As a result, the detection device 66 is set to the detection mode. At this time, the stamp main body A is placed in the pocket 6.
Is attached, the switch top 265 abuts against this, the detection switch 263 is turned off, and it is detected that the seal body A is attached (FIG. 2).
9). On the other hand, if the stamp body A is not attached, the switch top 265 is in the most protruding state, and the detection switch 263 is turned on to detect that the stamp body A is not attached.

Actually, when any one of the detection switches 263 in the switch array 262 is turned off, it is detected that the stamp main body A is attached, and all the detection switches 263 are detected. , When it is turned on, it is detected that the stamp body A is not attached.

As described above, the various stamp bodies A mounted in the pockets 6 are positioned by the boss 251 so that the centers of the stamp surfaces Ad are always at the same position. Therefore, by abutting the detection switch 263 on the central position of the back surface Ag of the stamp main body A, it is possible to reliably detect any stamp main body A. Further, the detection switch 263 is interlocked with the opening / closing of the opening / closing lid 7.
Since the seal is abutted against the seal body A, the detection switch (detection protrusion 267) 263 does not project into the pocket 6 when the seal body A is attached or detached, and the seal body A is smoothly attached and detached. be able to. Instead of switching the detection mode, the detection protrusion 267 of the switch top 265 shown in FIG. 26 may be retracted from the inside of the pocket 6 to detect that the opening / closing lid 7 is opened. Further, this may be used as a priority detection signal for blocking exposure.

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

FIG. 31 shows the relationship between the small hole Ah of the stamp main body A and the six detection switches (detection protrusions) 263. From the relationship between the six detection switches 263 and the presence / absence of the small hole Ah, 2 ⁿ −1 types of discrimination patterns, that is, 63 types of discrimination patterns are possible. In this case, there is no small hole Ah for the two detection switches 263, 263 at both outer ends of the stamp body A having a narrow width such as a square mark, and these two detection switches 263, 263 are the seals. It projects toward the space on both sides of the main body A. That is, in the seal main body A having a narrow width such as a square mark, an imaginary small hole Ah is formed at the outermost end of the seal main body A.
Is recognized as a discrimination pattern having

In other words, the number of discrimination patterns is reduced by assigning the discrimination pattern having the small hole Ah at the outermost end among the 63 types of discrimination patterns to the seal body A having a narrow width such as a square mark. Without any detection switch 26
The stamp main body A having a width that cannot be dealt with by 3 can be discriminated. It should be noted that the six detection switches 263 include a spare, and actually, the four detection switches 26 are included.
3 is sufficient.

The method of detecting the stamp body can be applied not only to the stamp body and the stamp creating apparatus but also to various electronic devices that receive different access objects.
