However, the web used in the conventional recording apparatus is wound in a roll around a core or the like, and the starting portion of the web is attached to the core with an adhesive tape or the like. I have. As described above, the recording apparatus using the web wound on the core does not include a means for separating the web from the core when the web is completely unwound from the core. It is necessary to interrupt the recording by leaving it to some extent. In this case, the recording is not performed on the web remaining on the winding core or on the label of the web remaining from the storage section in which the roll-shaped web is stored to the recording area, and the webs are discarded. That is, there is a problem that a label near the end of the web cannot be used, and the web is wasted. Although the waste of the web can be reduced by shortening the distance between the storage unit and the recording area, it is a constraint when configuring the recording apparatus, and there is a problem that the degree of freedom decreases when designing the recording apparatus. .

In the conventional recording apparatus, even if the end of the web is separated from the core and conveyed to the recording area,
No means is provided for detecting the end of the web. Therefore, when the end of the web is conveyed to the recording area through the recording area detection means, the recording area detection means does not detect the front end of the recording area on the downstream side in the web transport direction, and the recording apparatus does not operate. An error message is output from the recording apparatus as a result of a paper jam. When the error message is output in this manner, there is a problem that it cannot be determined whether or not the roll-shaped web is completely unwound from the storage unit without checking the recording device.

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, an object of the present invention is to provide a recording apparatus using a web wound in a roll shape with a recording area formed on the surface thereof. It is an object of the present invention to provide a recording apparatus in which the web is used effectively by performing recording on the web and the waste of the web is reduced.

[0014]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a storage section for storing a web, which is provided with a plurality of recording areas on its surface and which is wound in a roll shape, A transport unit that unwinds the web and transports the web to a recording area where recording is performed by a recording unit; a first detection unit that detects the presence or absence of the web in the storage unit; A second detection unit that is disposed on a transport path of the web up to an area and detects at least a leading end of each recording area on the surface of the web on a downstream side in the transport direction of the web; and the first and second detection units. A control unit that controls the recording unit and the transport unit based on the detection result of the detection unit, wherein the control unit performs the first detection operation during recording by the recording unit. After a specific time has elapsed from the time when it is detected that there is no web in the storage section, the second detecting means moves the web in the recording area on the surface of the web within a preset time. When the leading end on the downstream side in the direction is not detected, the recording by the recording unit is interrupted and a standby state is set.

Further, the specific time is set to be longer than a time required for moving an arbitrary portion of the web from the storage section to the position of the second detecting means by the transport means. preferable.

Further, a recording apparatus wherein the web is stored in the storage portion in a state where the web is wound around the core in a roll shape after one end of the web is bonded to the core. And separating means for separating the web from the core.

Further, the separating means is a frame member disposed on a side of a web transport path from the storage section to the second detecting means, and the web is completely unwound from the winding core. The shape of the frame member is configured such that the core is pulled through the web by the transport means and the core is brought into contact with the frame member, whereby the web is separated from the core. Is preferably formed.

Further, it is preferable that the separating means cuts a portion of the web near the core.

Further, after the first detecting means detects that there is no roll-shaped web in the storage portion by completely unwinding the web from the core by the conveying means, Preferably, a portion of the web near the core is cut off.

In the invention as described above, when the first detecting means for detecting the presence or absence of the roll-shaped web in the storage section detects that there is no roll-shaped web in the storage section during the recording by the recording means. If the second detecting means does not detect the front end of the web surface in the recording area on the downstream side in the transport direction within a preset time after a specific time has elapsed from, the recording by the recording means is interrupted. Thus, a recording apparatus having control means for setting a standby state is established.
In this recording apparatus, since the roll-shaped web of the storage section is completely unwound from the storage section by the transport means and the roll-shaped web is eliminated from the storage section, the first detection means has no roll-shaped web in the storage section. Is detected. Thereafter, the end of the web is transported from the storage section toward the recording area by the transporting means within a specific time. Where, for example,
If the length of the specific time is set to be longer than the time required for any part of the web to move from the storage section to the position of the second detection means, the end of the web is set within the specific time. Pass through the second detection means. Therefore, after the specific time has elapsed, the web does not exist in the portion of the web transport path where the second detection means is arranged, and the second detection is performed within a predetermined time after the specific time has elapsed. The means does not detect the recording area on the web surface. That is, if there is no web in the storage part,
If the second detecting means does not detect the recording area on the web surface within a preset time after a specific time has elapsed from the time when the detecting means has detected, the end of the web is recorded from the storage section. It can be determined that the sheet has been conveyed normally toward the area, and at that time, by interrupting the recording, the recording is performed on the recording area closer to the end of the web. As a result, waste of the web is eliminated, and the web can be used more effectively. By adjusting the length of the specific time or adjusting the position of the second detection means, the web can be used to the end without waste. Further, there is no need to shorten the distance between the storage section and the recording area in order to avoid wasting the web, and the degree of freedom in designing the recording apparatus is improved.

A web used in the above-described recording apparatus may be wound around a core in a roll shape. This web is stored in the storage section in a state where the web is wound around the core in a roll shape after one end of the web is bonded to the core. The recording apparatus using the web wound on the core in this manner was provided with a separating means for separating the web from the core. Thus, even if the end of the web is adhered to the core, the end of the web is separated from the core and conveyed from the storage section toward the recording area. Therefore, it is possible to perform recording on the recording area closer to the end of the web from the time when the web is completely unwound from the winding core until the specific time elapses as described above, and the waste of the web is reduced. Less.

That is, after the specific time t ₁ , the recording detection means 7 is set within a preset time.
Does not detect the leading end 9b of the label 9a, the printing of the print head unit 11 is interrupted by the control means, and the printing apparatus enters a standby state. At this time, an out-of-paper message is output to the recording device.

Therefore, when the web 3a is completely unwound from the storage section 1a and the web 3a is separated from the core 3b, the recording of the recording apparatus is interrupted after the end of the web 3a has passed the recording area detecting means 7. . As a result, the web 3a wound in a roll can be used to the end without waste. When an out-of-paper error message is issued, the user removes the supply unit cover 2 and stores another new roll-shaped web in the storage section 1a.

On the other hand, after a particular time t ₁ has elapsed since when the roll detecting means 6 does not detect the web 3a in the recording of the print head unit 11, the leading end 9b of the recording area detection means 7 labels 9a If detected,
The recording of the print head unit 11 is interrupted, and an error message indicating an abnormality of the supply unit is displayed on a display portion of the recording device.

As described above, in the recording apparatus of this embodiment, the web 3a is wound around the core 3b, but the roll-shaped web 3a may not be wound around the core 3b. In this case, the shape of the supply frame 8 need not be a shape that separates the web 3a from the winding core 3b.

As described above, in the recording apparatus of the present embodiment, while the print head unit 11 is recording,
After a lapse of a particular time t ₁ from when the roll detecting means 6 and the web 3a is no detected in a, the recording area detection means 7 within a preset time the tip 9b of the web 3a surface label 9a If no detection has been made, a control device is provided for suspending recording by the print head unit 11 and putting it in a standby state. With this configuration of the recording apparatus, recording is performed on the label at a position closer to the end of the web 3a, so that the waste of the web 3a is reduced and the running cost of the recording apparatus is reduced. Further, it is not necessary to shorten the distance between the storage portion of the web and the recording area in order to avoid wasting the web as in the conventional recording apparatus, and the degree of freedom in designing the recording apparatus is improved. .

(Second Embodiment) FIG. 4 is a view well showing a recording apparatus according to a second embodiment of the present invention. The recording apparatus of the present invention is different from the first embodiment in the internal configuration of the supply unit, and the other configurations are the same as in the first embodiment. In FIG. 4, the same components as those in the first embodiment are denoted by the same reference numerals. In the following, the first
The following description focuses on the differences from the first embodiment.

In the recording apparatus of the present embodiment, as shown in FIG. 4, a storage unit 41a provided with drive rollers 4 and 5 is provided inside a supply unit 41. As in the first embodiment, one end of the web 3a is adhered to the core 3b with an adhesive tape or the like, and then the web 3a is wound in a roll around the core 3b. The roll portion 3c, which is a roll-shaped web 3a, is placed in the storage portion 41a by being placed on the drive rollers 4 and 5 provided in the storage portion 41a.

Further, inside the supply unit 41, there is provided a supply frame 48 extending along the transport path of the web 3a unwound from the storage section 41a. The end of the supply frame 48 on the side opposite to the recording area side is

In the same manner as in the first embodiment, the downstream end of the label adhered to the surface of the web 3a at the same interval by the recording area detecting means 7 on the downstream side in the transport direction of the web 3a, and the transport direction of the label in the web 3a. The upstream end is detected.

FIG. 5 is a partially enlarged view for explaining the structure of the separation unit 32. FIG. 5 shows a state where the web 3a is completely unwound from the core 3b. As shown in FIG. 5, inside the separation unit 32,
A rotary blade 32a disposed on one side of the transport path of the web 3a and a fixed blade 32b disposed on the other side of the transport path of the web 3a are provided so as to sandwich the transport path of the web 3a. ing. The rotary blade 32a is rotated by obtaining power from a drive device (not shown) such as a motor via a power transmission device (not shown) such as a belt. Normally, in the state where recording is being performed, the blade edge of the rotary blade 32a does not face the transport path of the web 3a, and the rotary blade 32a does not rotate, so that the blade edge of the rotary blade 32a does not contact the web 3a. Therefore, usually, the rotary blade 32a
Even when the web 3a passes between the web 3a and the fixed blade 32b, the web 3a is not cut or damaged by the rotary blade 32a or the fixed blade 32b.

The core sensor 31 serving as the first detecting means is provided on the leading end surface of the supply frame 48 on the separation unit 32 side.
Is provided. When the web 3a is unwound from the core 3b, the core 3b is pulled by the web 3a,
The core 3b is moved from the position shown by the two-dot chain line in FIG.
And comes into contact with the core sensor 31. Thus, the core sensor 31 detects that the core 3b has contacted the core sensor 31. At this time, the storage section 41a
Does not have the rolled web 3a, the fact that the core sensor 31 detects the core 3b means that the storage section 41a has the rolled web 3a.
"a" is the same as detecting the absence. Immediately after the core sensor 31 detects the core 3b, the rotary blade 32a is rotated, and the rotary blade 32a and the fixed blade 3 in the web 3a are rotated.
2b is cut off. Thereby, the unwound web 3a is separated from the core 3b.

In the recording apparatus of the present embodiment, the core sensor 31 detects the core 3b during recording of the print head unit.
After ₂ specific time t from the time of detection, the recording area detection unit 7 may not detect the leading end of the label web 3a surfaces, to interrupt the recording by the print head unit in a predetermined time wait The control means performs control so as to set the state. In the standby state, a message of out of paper is issued to the recording device.

The length of the specific time t ₂ is set to be longer than the time required for moving an arbitrary portion of the web 3 a from the storage section 41 a to the position of the recording area detecting means 7 by the transport means. The length of this particular time t _2, the conveying speed and the web 3a, the length of the transport path of the web 3a, is determined from such time that the cutting of the web 3a by separating unit 32.

Next, the operation of the recording apparatus when the web 3a is completely unwound from the core 3b will be described with reference to FIG.

Therefore, when a specific time t ₂ has elapsed, the recording area detection unit 7 does not detect the leading edge of the label web 3a surface, recording apparatus enters a standby state recording is interrupted within a predetermined time . At this time, an out-of-paper message is output to the recording device.

As described above, in the recording apparatus of the present embodiment, the storage section 41a
Core 3b is removed from the core 3b.
After a particular time t ₂ has elapsed from the time it is detected, the recording area detection means 7 within a preset time web 3
When the leading end of the label on the front surface a is not detected, control means is provided for suspending recording by the print head unit and setting a standby state. Since the recording apparatus is configured as described above, recording is performed on the label at a position closer to the end of the web 3a, and the waste of the web 3a is reduced.
The running cost of the recording device is reduced. Further, it is not necessary to shorten the distance between the storage portion of the web and the recording area in order to avoid wasting the web as in the conventional recording apparatus, and the degree of freedom in designing the recording apparatus is improved. . Furthermore, since the separation unit 32 that cuts a portion of the web 3a near the core 3b is provided, the web 3a is reliably separated from the core 3b. Therefore, a highly reliable recording apparatus can be obtained.

In the recording apparatuses according to the first and second embodiments described above, a case is described in which recording is performed on a label disposed on the surface of the web 3a. However, the recording apparatus according to the present invention performs recording on a label. Also, the web is not limited to those described above. For example, the label may not be adhered to the surface of the web 3a, and the recording area may be formed directly on the surface of the web 3a. Also, Web 3a
As such, a cutout perforated may be used.

[0051]

As described above, according to the present invention, during recording by the recording means, a predetermined time has passed since the first detection means detected that the roll-shaped web did not exist in the storage section. When the second detecting means does not detect the leading end of the web surface in the recording area on the downstream side in the transport direction within the set time, the recording means suspends the recording by the recording means and sets a standby state. Therefore, the end of the web is conveyed to a position near the recording area within the specific time, and the recording is performed in the recording area closer to the end of the web. Therefore, the waste of the web is reduced,
This has the effect of reducing running costs. Also,
There is no need to shorten the distance between the storage unit and the recording area in order to reduce the waste of the web, and there is an effect that the degree of freedom of design is improved when designing the recording apparatus.

Further, the web used in the above-mentioned recording apparatus is such that the web is wound around the core in a roll shape after one end of the web is adhered to the core, and the web is wound around the core. Since the separating means for separating from the core is further provided, the end of the web is separated from the core and conveyed to the recording area, and recording is performed in the recording area closer to the end of the web. Therefore, even when one end of the web is bonded to the core, there is an effect that the waste of the web is reduced and the running cost is reduced.
