More specifically, it is detected that the cut sheet CS has been inserted by first blocking the light receiving surface on the light receiving element side of the photosensor PS2, and then the notch 91 reaches the position of the photosensor PS2. Thus, when the light reaches the light receiving element, it is detected that the cut sheet CS has reached the printing position.
[0035]
Note that the cut sheet CS used in the present embodiment is configured by an adhesive seal having a release sheet on the back surface. Therefore, after printing, the printing surface 93 in the central portion can be peeled off and attached to the upper surface of the handle 75 of the stamp body STP.
[0036]
Here, after describing the photosensor PS2 for detecting the cut sheet CS, other sensors provided near the printing unit will also be described.

The cam 42 is rotated to the state shown in FIG. 1 in the state where it is laid down in the horizontal direction, and the platen 44 is moved to a position away from the thermal head 41.
[0047]
Accordingly, by providing the front frame FR2 with the lock opening 121 having the shape as described above, the lever 49 is caught by the lock opening 121 when the platen 44 is pressed against the thermal head 41, and the front side It is devised so that the frame FR2 cannot be opened. As a result, the thermal transfer ribbon 50 is not accidentally removed when the ribbon RBN is sandwiched between the platen 44 and the thermal head 41, and damage to the ribbon RBN can be prevented. Similarly, the drawer unit 120 is not pulled out while the transparent film FLM is sandwiched between the platen 44 and the thermal head 41, and damage to the transparent film FLM due to an erroneous operation can be prevented.
[0048]
By the way, as shown in FIG. 10, the lever 49 is configured to engage with the back side of the opening / closing knob 131 of the front panel 130 and rotate in conjunction with the rotation of the knob 131. A micro switch MS3 is provided on the back side of the front panel 130 to detect when the lever 49 is raised, that is, when the platen 44 is pressed against the thermal head 41. The front frame FR2 described above is fixed to the back surface of the front panel 130.
[0049]
Next, the drive mechanism of the conveyance part of thermal transfer ribbon RBN, transparent film FLM, and cut sheet CS is demonstrated.
[0050]
As shown in FIG. 11, one step motor SM is provided as a drive source for the transport mechanism. FIG. 11 shows a state in which the drive system mounting frame FR3 provided on the further back side of the back frame FR1 is viewed from the front side.
[0051]
Here, the power is transmitted to the ribbon take-up roll drive shaft 151 of the thermal transfer ribbon cassette 50, the film take-up roll drive shaft 152 of the take-up roll cassette 30 of the transparent film FLM, and the transport roller 46 provided in the printing unit. And one feed roller 62 for the cut sheet CS.
[0052]
The rotation of the step motor SM is transmitted to the ribbon take-up shaft 151 via gears G1 to G5. The gears G1 to G3 are provided with two gears having different gear ratios on the same axis. Further, rotation is transmitted to the conveyance roller 46 of the printing unit via gears G1 to G3. Here, the ribbon take-up shaft 151 is configured to be able to slide in the reverse direction by the one-way clutch. The gear ratio is set so that the rotational speed of the ribbon take-up shaft 151 is about twice the rotational speed of the transport roller 46. This is because the ribbon RBN can be wound with the tension always applied even when the winding amount of the thermal transfer ribbon RBN around the ribbon winding shaft 151 changes.
[0053]
The film take-up shaft 152 is configured such that a driving force is transmitted by pulleys 153 and 154 and a timing belt 155. Further, a tension pulley 156 is provided in the middle so that the tension can be adjusted. The power of the step motor SM is transmitted to the pulley 153 on the left side of the figure via the gears G1 to G3 and the gear G6. A timing belt 158 is stretched between a pulley 156 having a small diameter provided coaxially with the pulley 153 and a pulley 157 fixed to the feeding roller 62. The film take-up shaft 152 is also attached with the same one-way clutch as the ribbon take-up shaft 151 so that the rotation speed of the film take-up shaft 152 is about twice that of the transport roller 46. Gear ratio and pulley diameter are set. This is because the transparent film FLM can be conveyed in a tensioned state even if the winding amount of the transparent film FLM around the film winding shaft 152 changes. Note that the rotational speed of the feeding roller 62 for the cut sheet CS is set to be slow, which is approximately 0.9 times the rotational speed of the conveying roller 46. This is because the cut sheet CS is pulled slightly when the cut sheet CS is fed so that the cut sheet CS can reach the printing unit with tension. The feeding roller 62 is also provided with a sliding mechanism using a one-way clutch.
[0054]
Next, drive control of the stamp manufacturing apparatus 1 of the present embodiment will be described.
As shown in FIG. 12, the stamp manufacturing apparatus 1 is connected to a personal computer PC so as to execute various operations such as printing a document, printing a label, and making a stamp plate according to control from the personal computer PC. It is configured.
[0055]
Next, drive control of the stamp manufacturing apparatus 1 of the present embodiment will be described.
As shown in FIG. 12, the stamp manufacturing apparatus 1 is connected to a personal computer PC so as to execute various operations such as printing a document, printing a label, and making a stamp plate according to control from the personal computer PC. It is configured.
[0056]
For this reason, the microcomputer 200 serving as a control center on the stamp manufacturing apparatus 1 side includes a PC interface control circuit 203 for fetching data from the personal computer 201, a thermal head control circuit 205 for driving the thermal head 41, and a step motor SM. Is connected to the step motor control circuit 207 for driving the Xenon tube, the xenon tube light emission control circuit 210 for causing the xenon tube 11 to emit light, the various photosensors PS1 to PS4 and the micro switches MS1 to MS3, and the liquid crystal display LCD. . A stamp size detection sensor 101 built in the stamp setting unit 100 is also connected to the microcomputer 200. This stamp size detection sensor 101 detects the length of the stamp body STP from the amount of movement of the front and rear clamping members when the stamp body STP is sandwiched from the front, rear, left and right by the stamp setting unit 100 so that the stamp size can be determined. It is composed of.
[0057]
Here, the stamp size detection sensor 101 and the stamp setting unit 100 will be described in detail.
The stamp setting unit 100, as shown in FIGS. 18 and 19, can be moved toward and away from the fixed frame 102 by sliding in the film transport direction with a fixed frame 102 provided on the original roll cassette 20 side. A main opening / closing door 103 provided, and driven doors 104 and 105 that slide in the film width direction and move toward and away from each other in conjunction with the sliding operation of the main opening / closing door 103, the fixed frame 102, the main opening / closing door 103. The stamp setting window W for sandwiching the skirt portion 73 of the stamp main body STP from the front, rear, left and right by the driven doors 104 and 105 is formed.
[0058]
The fixed frame 102 is cut to align the center line of the stamp body with the center line of the transparent film FLM by engaging the alignment protrusion 73d provided on the skirt portion 73 of the stamp body STP at the center in the film width direction. A notch 102a is provided.
[0059]
The main opening / closing door 103 is in contact with the fixed frame 102 by coil springs SP1 and SP1 stretched between an inverted U-shaped frame 103a fixed to the rear end (right side in the figure) and the fixed frame 102. It is energized so that it will be drawn to. The main opening / closing door 103 has parallelogram openings 103b, 103b as shown in the figure. The parallelogram-shaped opening 103b is another set of parallel so that the side H2 on the center line side of the sides H1 and H2 parallel to the film conveying direction is shifted backward from the side H1 on the outside. Sides (hereinafter referred to as “slanted sides”) H3 and H4 are formed. Moreover, the rear end edges 103c and 103c of the main door 103 are formed in parallel with the oblique sides H3 and H4.
[0060]
The driven doors 104 and 105 are connected by coil springs SP2 and SP2 that urge both ends of the driven doors 104 and 105 in a direction in which they are attracted to each other. In addition, two pins 104a, 104b, 105a, 105b are projected from the upper surfaces of the driven doors 104, 105, respectively. When the main opening / closing door 103 is in the closed state as shown in FIG. 18, when the main opening / closing door 103 is moved to the right in the drawing with the knob 103d, the driven doors 104, 105 are initially closed. However, when the pins 104a and 105a come into contact with the hypotenuses H3 and H3 and the pins 104b and 105b come into contact with the rear end edges 103c and 103c, they are pushed by the hypotenuse H3 and the driven doors 104 and 105 are opened. The state shown in FIG. 19 is the most open state. In this state, the stamp main body STP is placed so that the alignment projection 73d of the skirt portion 73 is aligned with the notch 102a of the fixed frame 102, and the main opening / closing door 103 is moved in the closing direction. As a result, the pins 104a and the like of the driven doors 104 and 105 are not obstructed by the hypotenuse H3 and the like, so that the driven doors 104 and 105 are moved toward each other by the action of the coil springs SP2 and SP2, and the side surfaces of the stamp body STP Sandwich. In this sliding operation, guide slits 106a to 106d are provided so that the driven doors 104 and 105 do not tilt, and guide pins 104c, 104d, 105c and 105d are inserted into the guide slits 106a to 106d. Yes.
[0061]
The frame 103a of the main opening / closing door 103 has a contact 103e that contacts a resistance wire 107 provided in the back of the stamp setting unit 100, thereby forming a slide volume type stamp size detection sensor 101. Yes.
[0062]
Next, the contents of the control process executed by the microcomputer 200 will be described based on a flowchart.
As shown in FIG. 13, when the stamp manufacturing apparatus 1 receives a document printing and plate making execution command from the personal computer 201 (S10), it drives the step motor SM and the thermal head 41 in accordance with the input stamp surface shape data. And a positive document is printed on the upper surface of the transparent film FLM (S20). Then, the step motor SM is driven by a predetermined amount so that the positive document reaches the plate making position, and the document setting operation is executed (S30). Then, it waits for the completion of the preparation of the stamp main body STP for plate making and the like to give a light emission command by the user (S40). When the user gives a light emission command (S40: YES), the process proceeds to a plate making operation described in detail later (S50). In the present embodiment, it is assumed that a light emission command is given by the user when the lid closed state is detected by the photosensor PS1 by closing the upper lid 3 and the upper front lid 5. On the other hand, when a heading label print command is received (S15), the heading label printing process is executed without performing the above-described processes of S20 to S50 (S60).
[0063]
Here, the plate making operation will be described in more detail.
Before that, first, the xenon tube light emission control circuit 210 will be described in detail. As shown in FIG. 14, the xenon tube light emission control circuit 210 includes a light emitting capacitor 211 that stores electric power for causing the xenon tube 11 to emit light, and a xenon tube light emitting capacitor charging that charges the light emitting capacitor 211. The circuit 213, a xenon tube light emitting capacitor charging voltage detection circuit 215, and a xenon tube light emitting circuit 217 that actually emits light from the xenon tube 11 are configured.
[0064]
In the plate making operation, as shown in FIG. 15, it is first determined whether or not the document is set at a predetermined position (S110). This is determined based on whether or not each of the document printing and document feeding operations is normally completed in accordance with a command from the personal computer 201. Next, it is determined whether or not the stamp body STP is set (S120). Here, it is determined that the stamp body STP is set when the detection voltage of the stamp size detection sensor 101 is larger than the minimum level by a predetermined value or more. Subsequently, it is determined whether or not the stamp size is correct (S130). This determination is performed by identifying the length of the stamp body STP from the detection signal of the stamp size detection sensor 101 and comparing this length with the length of the positive document input from the personal computer 201.
[0065]
Further, it is determined whether or not the upper lid 3 and the upper front lid 5 are closed (S140). This determination is performed based on the detection signal of the photosensor PS1 as already described. The detection signal of the photosensor PS1 has already been confirmed at the stage when it is determined in S40 that there has been an execution command for the plate making operation from the user, but the first light emission command itself may have been an erroneous determination. Because there is, there is again confirmation here.
[0066]
Next, it is determined whether or not the stamp main body STP is in a state where an appropriate amount of pressure is applied (S150). Specifically, this determination is made based on whether or not a predetermined time has elapsed since the upper lid 3 and the upper front lid 5 were closed. This is because it can be determined that the stamp main body STP is stable in a state where an appropriate amount of pressure is applied after a predetermined time has elapsed. Finally, it is determined whether or not the xenon tube 11 is in a state capable of emitting light (S160). This determination is made based on the detection voltage of the xenon tube light emitting capacitor charging voltage detection circuit 215.
[0067]
Only when it is determined “YES” in each of the above steps S110 to S160, a light emission command is output to the xenon tube 11 to emit it (S170), while any step of S110 to S160 is performed. If "NO" is determined in step S1, the emission to the xenon tube 11 is stopped (S180), and this process is terminated. As described above, when the stamp is made by making the xenon tube 11 emit light, a number of checks are performed to prevent a situation where an unnecessary plate making operation is executed due to an erroneous operation.
[0068]
Next, the heading label printing process will be described.
When the heading label printing process (S60) is started in the heading label printing mode, as shown in FIG. 16, first, it is determined whether or not the front edge of the heading cut sheet CS is detected by the photosensor PS2 (S210). ). Then, after the front end is detected, the step motor SM is driven, and the cut sheet CS is fed in until the notch 91 is detected by the photosensor PS2 (S220). When it is determined that the cut sheet CS is set at a predetermined position by detecting the cutout 91 of the cut sheet CS (S230: YES), the thermal head 41 and the step motor 11 are driven to use for the heading label. Printing is executed (S240). When the leading edge of the cut sheet CS is not detected by the photosensor PS2 (S210: NO), and when the notch is still not detected even after the predetermined amount of feeding is performed after the cut sheet feeding operation is performed (S250: YES), Error processing is executed (S260). In this error processing, for example, an appropriate measure such as displaying a message prompting insertion of the cut sheet CS on the liquid crystal display LCD on the upper surface of the main body may be taken.
[0069]
As described above, according to the stamp manufacturing apparatus 1 of the present embodiment, using a positive document, melting is performed in a state where a predetermined amount of the surface of the porous stamp surface forming member in which the light absorbing material is dispersed is crushed. Since a method of producing a stamp by solidifying is employed, post-treatment is easier than in the prior art using an ultraviolet curable resin, and storage of materials before plate making is easy.
[0070]
Further, since the stamp shape can be determined based on data from the personal computer 201, any data that can be output to a printer, such as image information captured by a digital camera or the like as well as characters created by a word processor, can be used. It is possible to easily manufacture stamps having a wide variety of stamp face shapes.
[0071]
In addition, it is easy to create a heading label using the cut sheet CS, and the heading label is printed while detecting that the heading label has been sent to the correct position, and the feeding speed of the heading label cut sheet CS is intentionally reduced. By doing so, the cut sheet CS can be sent to the printing site in a tensioned state. Therefore, no misalignment occurs in the printing of the headline label, and unnecessary printing is prevented.
[0072]
Further, with respect to the path for transporting the transparent film FLM from the printing unit P1 to the plate making unit P2, the configuration in which the width direction of the transparent film FLM is guided is adopted, so that the positive document can be set without being shifted to the correct position.
[0073]
Further, since the various cassettes are inserted and removed from the front side along the horizontal bars 111 to 116, the cassettes can be easily exchanged. Further, due to the relationship between the lever 49 and the notch 121 provided in the front side frame FR2, it is configured so that various cassettes cannot be replaced unless the head is released. This prevents damage to the thermal transfer ribbon RBN and damage to the transparent film FLM.
[0074]
In addition, since the width of the transparent film FLM is wider than that of the thermal transfer ribbon RBN, and the transport roller 46 having protrusions 46b that pierce the transparent film FLM and the thermal transfer ribbon RBN at the same time is used, the transparent film FLM and the thermal transfer ribbon are used during printing. No slip occurs between the RBN. Therefore, it is possible to create a positive document that is clear and free from fading.
[0075]
Further, the frames 51 and 21 are provided in the thermal transfer ribbon cassette 50 and the original film roll cassette 20 so that the thermal transfer ribbon RBN and the transparent film FLM immediately after printing are immediately separated from each other, and the cut sheet CS is immediately used as a guide 64. Since the structure in which the sheet is brought into contact with and guided to the upper outlet 65 is adopted, the separation between the cut sheet CS and the transparent film FLM is improved. Ideally, as shown in FIG. 17, the three members of the thermal transfer ribbon RBN, the cut sheet CS, and the transparent film FLM may be separated from each other at an angle of 45 degrees or more. By doing this, even if a sticking state due to static electricity or the like occurs between the cut sheet CS and the transparent film FLM, the cut sheet CS cannot follow the angle change of 45 degrees or more, and is sure. It is because it can isolate | separate into.
[0076]
Further, in the present embodiment, as shown in FIG. 5, the upper surface of the handle portion 75 of the stamp body STP is a curved surface. As a result, even if the pressing plate PL hits the handle portion 75 at a slight angle, alignment is automatically performed as a function of the curved surface, and the stamping surface forming member 81b is compressed into a substantially uniform state for plate making. Can do.
[0077]
Furthermore, in this embodiment, the xenon tube is configured to emit light when a plurality of conditions such as whether or not the stamp size is correct are satisfied during the plate making operation. Thereby, it is possible to prevent unnecessary plate making operations from being executed.
[0078]
Although not specifically described in the above embodiment, according to the present apparatus 1, when the microswitch MS1 is off, the thermal transfer ribbon cassette 50 is not mounted. When the microswitch MS2 is off, the transparent film When the microswitch MS3 is turned off to the effect that no cassette is mounted, it can be configured to respectively notify that it is in a head released state and printing cannot be performed. When the light transmission state is detected by the photosensor PS3, a message for instructing replacement of the thermal transfer ribbon cassette 50 is displayed, and when the light blocking state is detected by the photosensor PS4, replacement of the transparent film is instructed. It is also possible to display a message.
[0079]
As mentioned above, although embodiment of this invention has been described, this invention can be implemented in a various aspect further in the range which does not deviate from the summary.
[0080]
For example, as pointed out in the problem to be solved by the invention, even in an apparatus that manufactures a stamp having a stamped surface of an outline character using a negative original instead of a positive original, forgetting to set the original and performing a plate making operation In this case, the stamp face forming member is wasted, but it is wasted if such a configuration is adopted in which the light emitting unit emits light after determining completion of document setting similar to the above-described embodiment. Plate making can be prevented, and the present invention can be implemented as it is.
[0081]
Similarly, as pointed out in the problem to be solved by the invention, as a technique for preventing unnecessary plate-making operation, a negative resin such as carbon black or a porous resin that does not contain a light-absorbing substance as described above is used. Even when a configuration that restricts the light emission conditions is applied to a stamp manufacturing apparatus that melts and solidifies a portion of a negative document that is in contact with carbon by irradiating light while being pressed against the document, unnecessary plate making is not performed. It is exactly the same in that it can be
[0082]
【The invention's effect】
As described above, according to the present invention, a stamp that forms an ink non-exuded portion by partially melting and solidifying a porous resin-made stamping surface forming member that does not require time-consuming storage and post-processing after plate making. In the manufacturing apparatus, useless plate-making operation can be prevented.
[0083]
In particular, according to the stamp manufacturing apparatus of the first aspect, the plate making operation is performed even though the original is not set on the light emitting unit, or conversely, the stamp forming member is not set. Since no plate making operation is performed, power is not wasted. In particular, when a porous resin containing a light-absorbing substance is used as the stamp surface forming member as cited in claim 5, the effect of preventing waste of the stamp surface forming member due to forgetting to set the document is exhibited.
[0084]
Further, according to the second aspect of the present invention, it is possible to prevent the occurrence of a situation in which the ink non-exuded portion is not sufficiently melted and solidified due to insufficient light emission.
[0085]
Moreover, according to the apparatus of Claim 3, a user is not made dazzling.
[0086]
According to the apparatus of the fourth aspect, it is possible to prevent unnecessary plate making using an inappropriate printing surface forming member that is too small or too large with respect to the document size.
[0087]
Furthermore, according to the apparatus of the sixth aspect, it is possible to execute from the creation of the positive document to the plate making with one device, and automatically determine whether the positive document is set correctly from a series of operations. can do.
