The sheet storage portion 102 according to the present embodiment forms a recess protruding downward, which is a space for storing the roll main body 104, by forming an arc shape protruding downward as viewed from the left. The roll main body 104 is placed on the paper storage unit 102 with the width direction of the paper 103 constituting the roll main body 104 directed in the left-right direction. Thus, the roll main body 104 is accommodated in the recess of the paper accommodating portion 102 and is supported by the paper accommodating portion 102 from below so as to be rotatable around the axis of the roll main body 104.

  The paper storage unit 102 is provided with an opening 119 for allowing the paper 103 fed out from the roll main body 104 stored therein to pass therethrough.

  The printing unit 105 prints on the paper 103 fed out from the roll main body 104 as paper. Specifically, when the paper 103 fed out from the roll main body 104 is carried in, the printing unit 105 prints the paper 103 and discharges it. The printing unit 105 is physically a print head (not shown), a roller (not shown) for conveying the paper 103, a cutter (not shown) for cutting the paper 103, and a member for guiding the paper 103. The printing guide 120 is configured.

  The motor 107, the motor roller 108, the first guide roller 109, the second guide roller 110, and the belt 111 feed out the paper 103 from the roll main body 104 accommodated in the paper accommodating portion 102, and drive the paper 103 along the conveyance path. It is the structure for supplying the driving force to do.

  Specifically, the motor 107 is a member that supplies the above-described driving force, and the rotating shaft is rotated by electric power supplied from a power source (not shown). The motor roller 108 is a roller attached coaxially with the rotation shaft of the motor 107. The belt 111 is a flexible member forming a ring with a certain width for transmitting the driving force supplied from the motor 107, and is made of, for example, rubber or resin.

  The belt 111 is arranged so that the motor roller 108, the first guide roller 109, the second guide roller 110, the feed roller 115 (detailed later) and the transmission roller 113 (detailed later) are rotated in a predetermined direction in conjunction with each other. Has been. The first guide roller 109 and the second guide roller 110 are rollers for guiding the belt 111 and adjusting the tension of the belt 111.

  In FIG. 2, the rotation directions of the rollers 108 to 110, 112 to 113, and 115 to 116 are indicated by arrows on arcs, and the moving direction of the belt 111 is indicated by straight arrows.

  The pickup roller 112 and the transmission roller 113 are configured to rotate the roll main body 104 accommodated in the sheet accommodating portion 102.

  Specifically, as shown in FIG. 1, a part of the pickup roller 112 is disposed in the space of the sheet storage unit 102 in which the roll main body 104 is stored through the opening 119. As a result, the pickup roller 112 contacts the outer peripheral surface of the roll main body 104 accommodated in the paper accommodating portion 102 and rotates the roll main body 104 in a predetermined direction (counterclockwise in FIG. 1).

  The transmission roller 113 is a roller for receiving the driving force of the motor 107 via the belt 111 and transmitting the driving force to the pickup roller 112.

  The separator 114, the feed roller 115, the pinch roller 116, and the conveyance guides 117 a and 117 b are configured to convey the paper 103 constituting the roll paper 100 along a conveyance path through which the paper 103 passes from the paper storage unit 102 to the printing unit 105. It is a configuration.

  More specifically, the separator 114 is inserted between an extended portion 122 (details will be described later) included in the roll paper 100 and the roll main body 104 so that the fixing portion 123 (details will be described later) is separated from the roll main body 104 and conveyed. It is a member for guiding to the road.

  The separator 114 according to the present embodiment includes a tapered portion 121 that is tapered toward a space in which the roll main body 104 is accommodated when the printer 101 is viewed from the side (left or right). As shown in FIG. 1, the tip of the tapered portion 121 is positioned in the opening 119. By having such a tapered portion 121, it becomes easy to insert between the extended portion 122 (detailed later) and the roll body 104 as will be described in detail later.

  The side of the printer 101 is in the width direction of the paper 103 constituting the roll main body 104 accommodated in the paper accommodating portion 102, and in other words, in the axial direction of the roll main body 104 accommodated in the paper accommodating portion 102. is there.

  The feed roller 115 drives the paper 103 by rotating in close contact with the paper 103 fed out from the roll main body 104.

  The pinch roller 116 is a roller that sandwiches the paper 103 fed from the roll body 104 with the feed roller 115. The pinch roller 116 exerts a force on the paper 103 to press the paper 103 against the feed roller 115 by the action of a biasing member such as a spring.

  The conveyance guides 117a and 117b are members for guiding the paper 103 fed from the roll main body 104 along the conveyance path in the conveyance path from the paper storage unit 102 to the printing unit 105. The conveyance guides 117a and 117b according to the present embodiment are provided in portions that are not guided by the feed roller 115 and the pinch roller 116.

  More specifically, the conveyance guide 117a forms a conveyance path for guiding the paper 103 from between the pickup roller 112 and the separator 114 to the feed roller 115 and the pinch roller 116, as shown in FIG. The conveyance guide 117 b forms a conveyance path for guiding the paper 103 from the feed roller 115 and the pinch roller 116 to the printing unit 105.

  The sensor 118 detects that the paper 103 fed out from the roll main body 104 passes through a predetermined position on the conveyance path. In the present embodiment, the sensor 118 detects the passage of the paper 103 at a position downstream of the feed roller 115 and the pinch roller 116 in the conveyance path from the paper storage unit 102 to the printing unit 105.

  So far, the configuration of the printer 101 according to the present embodiment has been described. From here, the structure when the roll paper 100 which concerns on this Embodiment is not used is demonstrated.

  When the roll paper 100 according to the present embodiment is not used, the roll paper 100 includes an extending portion 122 in addition to the roll main body 104 as shown in FIG. Note that the two-dot chain line in FIG. 3 is a virtual line.

  The extending portion 122 is connected to the terminal end TP of the roll main body 104 and extends a predetermined length L in a direction perpendicular to the width direction of the strip-shaped paper 103 constituting the roll main body 104.

  The length of the extended portion 122 is longer than the length of the conveyance path from the position P where the extended portion 122 is extended from the paper storage portion 102 to the position Q where the feed roller 115 is in close contact (see FIG. 6). In the present embodiment, the position where the extended portion 122 is drawn out from the paper storage portion 102 is the position of the tip of the tapered portion 121.

  The roll main body 104 includes a fixing portion 123 that fixes the vicinity of the terminal end TP of the paper 103 constituting the roll main body 104 in a peelable manner. Specifically, the fixing unit 123 includes at least a part of the inner surface 125 of the paper 103 located in a predetermined range (fixing region) 125 from the terminal end TP, and the outer surface 126 of the paper 103 wound around the roll main body 104. The outer surface 126 facing at least a part of the inner surface is fixed to be peelable.

  Here, the inner surface 125 of the paper 103 is a surface facing inward, that is, a surface facing the axis of the roll body 104, and the outer surface 126 of the paper 103 is a surface facing outward, that is, the inner surface 125 of the paper 103. It is the opposite side.

  In FIG. 3, the fixing region 124 is a range sandwiched between the terminal portion TP and the separation portion VL. The separation portion VL is a portion that is separated from the end portion TP by a predetermined distance in a direction perpendicular to the width direction, and is a portion parallel to the end portion TP.

  The fixing portion 123 according to the present embodiment is provided at the center in the width direction of the paper 103 located in the fixing region 124.

  The fixing unit 123 fixes the inner surface 125 and the outer surface 126 of the paper 103 so as to be peelable as described above by an adhesive force such as glue, bond, double-sided tape, or the like.

  Here, the peelable means that the fixed paper 103 can be peeled without breaking the fixing portion 123 and its vicinity by pulling the extending portion 122 as described later. As such a fixing method, not only the above-described adhesive force, but also a method of pressing the papers 103 or folding the papers 103 together with a stapleless stapler, for example, may be employed.

  Up to this point, the configuration of the roll paper 100 according to the embodiment of the present invention and the printer 101 that uses the roll paper 100 as the paper has been described. The operation from when the unused roll paper 100 is set in the printer 101 until it can be printed on the paper 103 as shown in FIG. 1 will be described with reference to FIGS.

  4 to 7 are diagrams showing stepwise changes in the state from when the unused roll paper 100 is set in the paper storage unit 102 to when the fixing unit 123 is peeled off. 4 to 7 are left side views showing the vicinity of the conveyance path from the sheet storage unit 102 to the sensor 118 in an enlarged manner. Also, dotted ellipses F1 to F3 attached to the roll body 104 in FIGS.

  The unused roll paper 100 is placed on the paper storage unit 102 with the extending portion 122 extending in the forward direction. When the motor 107 is driven, the pickup roller 112 rotates, and the roll paper 100 rotates, for example, counterclockwise in FIG. The extending portion 122 is not glued to the roll body 104 and is peeled off from the beginning. Therefore, as shown in FIG. 4, the distal end of the extending portion 122 is guided by the distal end of the tapered portion 121 having a tapered shape, and proceeds to the lower side of the separator 114. As a result, the extending portion 122 is separated from the roll body 104.

  The leading end of the extending portion 122 is guided in order by the separator 114 and the conveyance guide 117a, and passes between the feed roller 115 and the pinch roller 116 as shown in FIG. Accordingly, the extending portion 122 is pushed in the transport direction by the rotational force of the pickup roller 112 and is pulled in the transport direction by the rotational force of the feed roller 115.

Subsequently, when the position of the fixing portion 123 exceeds the position of the pickup roller 112, the fixing portion 123 is gradually peeled from the roll body 104 by the pulling force of the feed roller 115. And
When at least a part of the fixing portion 123 has not been peeled off until it contacts the separator 114, the fixing portion 123 is peeled off by the pulling force of the feed roller 115 while hitting the tip of the taper portion 121 as shown in FIG. The

  Since the fixing portion 123 only needs to be peeled off by the pulling force of the feed roller 115, the strength against pulling of the paper 103 constituting the roll paper 100> the magnitude of the force with which the pinch roller 116 presses the paper 103 against the feed roller 115> fixed The fixing force of the portion 123 (in this embodiment, an adhesive force) is preferable.

  The separator 114 is a member for separating the extended portion 122 from the roll main body 104 and guiding it to the conveyance guide 117a, and is not a member for contacting the fixing portion 123 and peeling the paper 103 from each other. Therefore, the taper portion 121 included in the separator 114 may not be provided at a position where the tip thereof contacts the outer peripheral surface of the roll body 104. In this case, the position P at which the extended portion 122 is drawn out from the paper storage portion 102 may be considered as a position that contacts the pickup roller 112, for example.

  Eventually, as shown in FIG. 7, all the fixing parts are peeled off. Then, the paper 103 constituting the roll main body 104 is sequentially fed from the paper storage unit 102 and conveyed to the printing unit 105. If the loaded paper 103 is printable, the printing unit 105 prints on the paper 103. Further, the printing unit 105 cuts the paper 103 and discharges it to the outside when there is a possibility that the printing is shifted.

  According to the present embodiment, it is not necessary for the user or the like to peel off the fixing portion 123 of the unused roll paper 100, and the user can save time and effort.

  Further, since the extending portion 122 provided in the unused roll paper 100 is peeled from the roll main body 104 from the beginning, the end of the extending portion 122 is sandwiched between the feed roller 115 and the pinch roller 116 to feed the feed roller. Can be pulled with. Therefore, the paper 103 fixed by the fixing part 123 can be reliably peeled off.

  Therefore, it can be set easily and reliably without any user effort.

For example, the present invention includes a form in which some or all of the embodiments described above and the modifications described below are appropriately combined, and a form in which the form is appropriately changed.

  For example, in the embodiment, the example in which the fixing unit 123 is provided in the center in the width direction of the paper 103 positioned in the fixing region 124 has been described. However, the aspect of the fixing portion 123 is not limited to this.

  For example, like the roll paper 200 shown in FIG. 8, the fixing portions 223 may be provided at both ends in the width direction of the paper 103 positioned in the fixing region 124.

  For example, like the roll paper 300 shown in FIG. 9, the fixing portion 323 may be continuously provided in a straight line extending in the width direction of the paper 103 positioned in the fixing region 124. For example, like the roll paper 400 shown in FIG. 10, the fixing portion 423 may be continuously provided in a zigzag shape extending in the width direction of the paper 103 positioned in the fixing region 124. For example, like the roll paper 500 shown in FIG. 11, the fixing portion 523 may be continuously provided in a wave shape extending in the width direction of the paper 103 positioned in the fixing region 124.

  For example, like the roll paper 600 shown in FIG. 12, the fixing unit 623 may be provided intermittently in a straight line extending in the width direction of the paper 103 positioned in the fixing region 124. Although not shown, the fixing portion may be provided intermittently in a zigzag shape or a wave shape extending in the width direction of the paper 103 positioned in the fixing region 124.

  These modifications also have the same effects as the embodiment.
