Description

  The present invention relates to a holder for supplying a material to be processed, a recording apparatus having the same, a method for switching supply of a material to be processed, and a recording method including the same.

  Conventionally, when recording on a web-like material to be processed (for example, continuous paper) by a recording device, a continuous paper is fed from the roll body using a holder that holds the roll body on which the continuous paper is wound. It is transported to the recording unit. On the other hand, when recording on a sheet-like material to be processed (for example, cut sheet paper), using a tray on which cut sheet sheets are stacked, the cut sheet sheets are taken out from the tray one by one and sent to the recording unit. Conveying. When switching between recording on continuous paper and recording on cut sheet paper, it is necessary to appropriately replace the holder for continuous paper and the tray for cut sheet paper. However, the work of exchanging the continuous paper holder and the cut paper tray is troublesome, and every time it is exchanged, the work of setting or removing the leading edge of the continuous paper in the transport mechanism of the recording device is necessary. Therefore, frequently switching between recording on continuous paper and recording on cut paper is very complicated and inefficient.

Therefore, Patent Document 1 discloses a paper feeding device that can easily switch between recording on continuous paper and recording on cut paper. In this apparatus, by operating the switching lever, the detection switch is activated and the CPU switches the paper feeding mode. That is, mechanically linked to the operation of the switching lever or electrically controlled by the CPU, the rotation direction of the gears and rollers, the position of the planetary gear, the meshing of the gears, and the like are switched, and the continuous paper Sheet feeding and cut sheet feeding can be switched.
JP-A-5-221541 ([0009] to [0012], FIGS. 1, 3 to 5)

  In the configuration described in Patent Document 1, the user can easily switch between recording on continuous paper and recording on cut paper by operating a switching lever. However, in order to enable this switching, a complicated mechanism consisting of a large number of gears, levers, and the like is required inside the paper feeding device, and further, in order to electrically control the driving of the gears, rollers, etc. An electric circuit including electric components such as a CPU and a detection switch is required. As described above, in the configuration described in Patent Document 1, even if the user's work is only the operation of the switching lever, various mechanical processes and electrical processes must be performed inside the apparatus. Therefore, the configuration is quite complicated.

  In the configuration of Patent Document 1, the cut sheet and the continuous sheet are sent to the sheet detector through different paths. That is, the cut sheet is sent to the paper detector through the lower part of the paper feed roller, and the continuous paper is sent to the paper detector through the upper part of the paper feed roller. Therefore, it may be necessary to provide a guide member in each of the two paths, and the apparatus may be increased in size to secure the two paths.

  Therefore, an object of the present invention is to switch between the supply of a web-like material to be processed such as continuous paper and the supply of a sheet-like material to be processed such as cut sheet paper, which does not require electrical processing and is very simple. A processing material supply holder and a processing material supply method that can be easily performed with an inexpensive configuration, a recording apparatus having the processing material supply holder, and a recording method including the processing material supply switching method are provided. There is.

  The holder for supplying a material to be processed according to the present invention is provided in a housing capable of accommodating a roll body around which a web-like material to be processed is wound, a sheet insertion opening provided in the housing, and the housing. The web-like material to be processed fed from the roll body and the sheet-like material to be processed inserted from the sheet insertion port can be sent to the outside of the housing, and can be rotatably attached to the housing. Lever, which is provided on the lever, and in which the roll body is held and the roll body can be rotated together with the rotation of the lever, and the roll body can be rotated independently of the lever. A holding portion capable of selectively taking a state, and a lid that is provided on the lever and is movable between a position for closing the sheet insertion opening and a position for opening the sheet insertion opening by rotation of the lever.

  In the description of the present specification, the “web-like material to be treated” mainly refers to continuous paper, but also includes materials other than paper, for example, a long material to be treated such as synthetic resin or cloth. The expression “sheet-like processed material” mainly refers to a cut sheet paper, but also includes a sheet-like processed material made of a material other than paper, for example, a synthetic resin or cloth.

  According to this configuration, the user can easily switch between the supply of the web-shaped material to be processed and the supply of the sheet-shaped material to be processed by manually operating the lever. Since electrical processing and complicated engagement operations are not performed at the time of supply switching, no special electric circuit configuration or complicated mechanism is required. In addition, since the web-like material and the sheet-like material can be supplied through the same route, the configuration is very simple and the cost can be reduced, contributing to the downsizing of the entire apparatus. In addition, since the sheet insertion port is closed by the lid when the web-shaped processing material is supplied, the user can be prevented from erroneously inserting the sheet-shaped processing material.

  The holding portion is provided at the center of rotation of the lever. By moving the lever in the horizontal direction, the holding portion is pressed into the core of the roll body to hold the roll body, and escapes from the center of the roll body. The non-bonded state may be switched. In this case, the operation is very simple because the user switches the supply of the material to be processed only by performing the operation of sliding the lever in the horizontal direction and the operation of rotating the lever around the rotation center portion.

  The recording apparatus of the present invention includes a workpiece supply holder configured as described above, a transport mechanism that transports a workpiece that is sent out from a delivery port of the workpiece supply holder, and a workpiece that is transported by the transport mechanism. And a recording unit for recording on the material.

  The processing material supply switching method of the present invention is provided at the center of rotation of a lever that is rotatably attached to a housing that houses a roll body around which a web-shaped processing material is wound. A first step of press-fitting the holding part into the core part of the roll body, and rotating the lever in the first direction around the rotation center part to reversely rotate the roll body integrally with the holding part, A second part that winds up a part of the web-like material to be processed and moves the lid provided on the lever from a position for closing the sheet insertion opening provided on the housing to a position for opening the sheet insertion opening. And a third step of inserting a sheet-like material to be processed from the opened sheet insertion port and projecting from the delivery port.

  By rotating the lever in the second direction around the center of rotation and rotating the roll body in a positive direction integrally with the holding unit, the tip of the web-shaped workpiece is projected from the delivery port, and the lid The step may further include a fourth step of moving the part from a position where the sheet insertion port is opened to a position where the sheet insertion port is closed, and then allowing the lever holding part to escape from the core of the roll body. Then, when switching from the supply of the web-like material to the supply of the sheet-like material, the first to third steps are performed in order, and the supply of the web-like material is supplied from the supply of the sheet-like material. When switching to, the fourth step may be performed. Thereby, the supply of the web-like material to be processed and the supply of the sheet-like material can be switched repeatedly by a very simple operation of the lever. There is no need to set or release the tip of the material to be processed each time the supply is switched, and the operation is very simple.

  The recording method of the present invention includes the steps of the above-described processing material supply switching method, and the step of conveying the processing material protruding from the delivery port and recording on the processing material.

  The method and apparatus described above are particularly suitable for a widespread type apparatus in which the frequency of supply of the material to be processed is high, or where cost reduction and downsizing are desired.

  According to the present invention, the user can easily and manually switch between the supply of the web-like processing material and the supply of the sheet-like processing material, and no electrical processing is required. An electric circuit configuration and a complicated mechanism are not required. In addition, since the web-like material and the sheet-like material can be supplied through the same route, the configuration is very simple and the cost can be reduced, contributing to the downsizing of the entire apparatus. Further, it is possible to prevent the user from mistakenly inserting the sheet-like material when supplying the web-like material.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 and 2 show a paper feed holder (processing material supply holder) 1 of the present embodiment. The paper feed holder 1 includes a housing 2 composed of an upper member 2 a and a lower member 2 b shown in FIG. 3 and a lever 3 attached to the housing 2. The housing 2 can accommodate a roll body 4 in which a web-like material to be treated (continuous paper in the present embodiment) is wound in a roll shape, and a delivery port 5 for delivering the material to be treated to the outside; A cut sheet paper insertion port (sheet insertion port) 7 into which a sheet-like material to be processed (in this embodiment, a cut sheet 19 (see FIG. 6A)) is inserted, and a bearing portion 8 are provided.

  The base portion 6 of the lever 3 shown in FIG. 4 is formed of a bent and elongated wire-like member, and both end portions of the elongated base portion 6 face each other with a space therebetween. A straight line portion connected to both end portions is a rotation center portion 9 held by the bearing portion 8 of the housing 2. Further, the lever 3 has a large-diameter holding portion 10 provided at the rotation center portion 9 and a lid portion 11 parallel to the rotation center portion 9. The entire width of the lever 3 is wider than the width of the housing 2, and the lid 11 is large enough to close the cut sheet insertion slot 7 of the housing 2. The holding unit 10 has a diameter that is the same as or slightly larger than the core (center hole) of the roll body 4, and is in a combined state that is press-fitted into the core of the roll body 4 and integrated with the roll body 4; It can escape from the core part of the roll body 4 and can be in a non-coupled state that is relatively rotatable with respect to the roll body 4.

  When the upper member 2 a and the lower member 2 b are joined while sandwiching the rotation center portion 9 of the lever 3, the housing 2 is configured, and the rotation center portion 9 of the lever 3 is supported by the bearing portion 8. Since the lever 3 has a width wider than the width of the housing 2, the lever 3 can slide in the horizontal direction (arrow A, B direction) with respect to the housing 2, and the rotation center 9 is the center, that is, It is held in the housing 2 so as to be rotatable about the bearing portion 8 (in the directions of arrows C and D). In the present embodiment, the lever 3 is positioned between the state in which the lever 3 stands vertically upward (the state shown in FIGS. 2 and 6) and the state in which the lever 3 is positioned horizontally (the state shown in FIGS. 1 and 5). It can rotate in an angle range of about 90 degrees.

  The operation of the paper feed holder 1 having the above-described configuration will be described with reference to FIGS. Here, a state in which the paper feeding holder 1 is attached to the recording unit 12 is illustrated. The recording unit 12 is provided with an inlet 14 and an outlet 15 for a material to be processed in a housing 13. Inside the housing 13, a platen roller 16 constituting a transport mechanism, a transport roller (not shown), and a sensor are provided. 17 and a recording head 18 that is in contact with the platen roller 16 constituting the recording unit.

  When the continuous paper is fed using the paper feeding holder 1, as shown in FIGS. 1 and 5, the roll body 4 is accommodated in the housing 2, and the continuous paper fed out from the roll body 4. The front end 4a of this is protruded from the delivery port 5. The leading end 4 a of the continuous paper protruding from the delivery port 5 enters the inside of the recording unit 12 through the introduction port 14 and passes between the platen roller 16 and the recording head 18.

  By rotating the platen roller 16 and a conveyance roller (not shown), the continuous paper is sequentially fed out from the roll body 4 and passes through the feed outlet 5 and the inlet 14 from the paper feed holder 1, and the casing 13 of the recording unit 12. It is conveyed inside. The continuous paper is recorded by the recording head 18 in contact with the platen roller 16, and the recorded continuous paper is discharged from the discharge port 15 to the outside of the housing 13. At this time, the lever 3 of the paper feed holder 1 is in a horizontal position (the state shown in FIGS. 1 and 5), and the lid 11 closes the cut sheet insertion slot 7, so that the user can mistakenly The slip sheet 19 is prevented from being inserted into the cut sheet insertion slot 7. The large-diameter holding portion 10 of the lever 3 is not press-fitted into the core portion of the roll body 4, and the roll body 4 can be freely rotated without being regulated by the holding portion 10 of the lever 3.

  When switching from continuous paper feeding to single-sheet paper 19 (see FIG. 6A) using the paper feeding holder 1, first, the lever 3 is moved in the lateral direction (paper width direction of the roll body 4). The large-diameter holding part 10 is press-fitted into the core part of the roll body 4 by horizontally sliding in the direction of arrow A. Subsequently, the lever 3 is moved from the horizontal position (the state shown in FIGS. 1 and 5) to the vertically raised state (the state shown in FIGS. 2 and 6) in the first direction (arrow C direction). Rotate about 90 degrees. By the rotation of the lever 3, the holding unit 10 and the roll body 4 in which the holding unit 10 is press-fitted into the core part are reversely rotated integrally, and the continuous paper that has been fed out from the roll body 4 and protrudes from the delivery port 5 is formed. The tip portion 4 a is rewound inside the delivery port 5, that is, inside the housing 2. In this embodiment, the unwinding amount of the continuous paper is about 3 to 5 cm. Further, by the rotation of the lever 3, the lid portion 7 moves from a position for closing the cut sheet insertion slot 7, and the cut sheet insertion slot 7 is opened.

  Therefore, as shown in FIG. 6A, the user inserts the cut sheet 19 from the cut sheet insertion slot 7 and pushes it in until it protrudes from the delivery port 5. When the leading end 19a of the cut sheet 19 reaches the inside of the housing 13 of the recording unit 12 from the introduction port 14, the sensor 17 detects it and drives a conveyance roller (not shown) to remove the cut sheet 19 It is conveyed to the position of the platen roller 16 and the recording head 18. Thereafter, the platen roller 16 and a conveyance roller (not shown) rotate, whereby the cut sheet 19 is conveyed and recorded by the recording head 18 and discharged from the discharge port 15 to the outside of the housing 13. At this time, the large-diameter holding portion 10 of the lever 3 is press-fitted into the core portion of the roll body 4, and the roll body 4 does not rotate unless the lever 3 rotates. Therefore, the roll body 4 accommodated in the housing 2 does not rotate carelessly and the continuous paper is not unnecessarily drawn out or rewound.

  When the recording of the cut sheet 19 is completed and discharged from the discharge port 15, when switching to continuous paper feeding again, the large-diameter holding part 10 of the lever 3 is press-fitted into the core part of the roll body 4. In a state where the lever 3 is left standing, the lever 3 is moved in the second direction (arrow D) from a state where the lever 3 stands vertically upward (a state shown in FIGS. Direction). By the rotation of the lever 3, the holding portion 10 and the roll body 4 in which the holding portion 10 is press-fitted into the core portion integrally rotate positively, the continuous paper is fed out from the roll body 4, and the leading end portion 4a is It protrudes from the delivery port 5 and enters the inside of the housing 13 of the recording unit 12 from the introduction port 14. When the sensor 17 detects the leading edge 4a, a conveying roller (not shown) is driven to convey the continuous paper leading edge 4a to the positions of the platen roller 16 and the recording head 18. The continuous paper is recorded by the recording head 18 while being transported by the platen roller 16 and a transport roller (not shown).

  By the rotation of the lever 3, the lid 7 moves from a position where the cut sheet insertion slot 7 is opened to a position where the cut sheet insertion slot 7 is closed. Therefore, the user does not accidentally insert the cut sheet 19 in a state in which continuous paper is fed. As described above, the cut sheet 19 can be inserted by the user only when the lever 3 is rotated and the cut sheet insertion opening 7 is opened.

  In this embodiment, as shown in FIGS. 5 (a) and 6 (a), the protrusion 2 is provided on the upper member 2a of the housing 2, and the lever 3 is raised vertically upward (FIGS. 2 and 6). 2) and a horizontally positioned state (shown in FIGS. 1 and 5), so that they are not inadvertently moved from these states. These protrusions 20 can be easily overcome by the lever 3 when the user intentionally rotates the lever 3, but are formed in such a size and shape that it is difficult for the lever 3 to get over by unintended vibration or external force. ing. Specifically, for example, a protrusion having a height of about several millimeters and a spherical cross section is formed. The protrusion 20 is shown only in FIGS. 5 (a) and 6 (a), and is omitted for simplification in other drawings.

  Although the holding part 10 of this embodiment consists of elastic members, such as rubber | gum, and it press-fits in the core part of the roll body 4, it is not limited to this structure. It is a mechanical lock mechanism provided in a part of the elongated wire-like base 6 (rotation center 9), in which the roll body 4 is locked and the roll body 4 is unlocked. It may be switched appropriately. Further, the holding unit 10 may incorporate a one-way clutch.

  In the configuration shown in FIG. 7, a guide portion 2 c is formed on the bottom surface of the lower member 2 b of the housing 2 to smoothly guide the continuous paper and the cut sheet 19 to the delivery port 5. Other configurations are the same as those described above with reference to FIGS. By this guide part 2c, the material to be fed can be smoothly guided to the delivery port 5 when the material to be treated is switched. In particular, when the feeding of the cut sheet 19 is started, the operation for the user to push the cut sheet from the cut sheet insertion slot 7 to reach the outlet 5 becomes very easy by the guide portion 2c. , Become more reliable. Although not shown, the guide portion 2c may be formed as a separate member from the lower member 2b of the housing.

  In the above-described embodiment, the recording apparatus in which the paper feeding holder 1 of the present invention is attached to the recording unit has been described. However, the paper feeding holder 1 of the present invention can be attached to various apparatuses other than the recording apparatus.
