Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper supply mechanism capable of supplying both roll paper and folded paper.

For example, a printer that prints an address of a courier service on a label prints a roll paper or a fold sheet to which an address label is stuck, but both the roll paper and the continuous fold sheet are printed by the same printer. There is a need for a paper supply mechanism that can supply paper.

[0003]

2. Description of the Related Art For example, a paper supply mechanism provided in a label printer has two types of paper, one dedicated to roll paper and the other dedicated to folded paper.
Types, each of which is a separate paper supply mechanism.

A paper supply mechanism dedicated to roll paper has a roll paper storage unit 13 in front of a feed roller 11 for feeding a printing unit (not shown) as shown in a schematic side view of FIG. The roll paper storage unit 13 has a box shape with an open upper part capable of storing the roll paper 10, and includes a pair of U-shaped bearings 14 whose upper parts are cut off on the left and right sides in a direction perpendicular to the paper supply direction. The bearing 14 removably supports both ends of the support shaft 15 inserted through the hollow core tube 10a of the roll paper 10 with a spring property and without rotating.

[0005] The starting end of the loaded roll paper 10 is set by manually inserting it into a feed roller 11 that is driven to rotate under the guide bar 12, and the feed roller 11 feeds out to a printing section (not shown). .

On the other hand, a paper supply mechanism dedicated to folding paper is provided with a feed roller 11 as shown in a schematic side view of FIG.
Is set by inserting the start end of the folded sheet 20 by hand into the feed roller 11 which is driven to rotate under the guide bar 12, and the feed roller 11 is similarly fed to the printing section. ing.

[0007]

However, according to the above-described paper supply mechanism, the paper supply mechanism is different between the roll paper and the fold paper, and therefore, the roll paper and the fold paper are separate dedicated printers. If the user wants to change it, it is necessary to obtain a special printer suitable for the change, which is uneconomical.

Therefore, if a fold sheet is placed in front of the roll paper storage section of a printer dedicated to roll paper and the roll paper storage section is to be used, the operability is poor because the roll paper storage section is in the way. There is a problem that it cannot be used because it is a printer.

In view of the above problems, it is an object of the present invention to provide a paper supply mechanism that can easily supply both roll paper having various paper widths and continuous folded paper with the same apparatus.

[0010]

According to a first aspect of the present invention, there is provided a paper supply mechanism having bearings for supporting both ends of a support shaft for rotatably supporting roll paper. A roll paper storage section, a folding paper storage section provided in front of the roll paper storage section, and a pivotally pivotally attached to the front and rear upper edges of the roll paper storage section,
When the foldable paper is used, the foldable paper is composed of a pair of guide plates which are raised from both sides to the support shaft supported by the bearing and guide the foldable paper.

With this configuration, when the roll paper is used, the roll paper can be mounted on the support shaft, supported by the bearing of the roll paper storage unit, and supplied to the rear feed roller.
Also, when using foldable paper, turning the guide piece and raising it over the support shaft from both sides allows it to cover the roll paper storage unit and receive and guide the foldable paper from below. Similarly, it can be easily supplied with good operability.

According to a second aspect of the present invention, the support shaft includes a fixed flange for regulating one ear end of a sheet to be used to a reference position, and a movable flange capable of adjusting a distance between the fixed flange and the fixed flange. The guide plate is divided into a plurality of guide pieces so as to have a sheet width of a sheet to be used.

With this configuration, when the roll paper is used, the position can be easily adjusted for various widths of the roll paper to be used by moving the moving flange to sandwich the roll paper.

Also, when using folded paper, only the guide piece corresponding to the paper width is raised from among the divided guide pieces of the guide plate, and is bridged from both sides to the support shaft, and the raised guide piece is used as a gauge for the paper width. By moving the moving flange, the guide piece and both flanges can be easily adjusted in position according to different paper widths of the folded paper, and the folded paper can be smoothly guided over the roll paper storage portion. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The gist of the present invention will be described below in detail with reference to the embodiments shown in the drawings. Note that the same reference numerals are used for the parts described in the conventional drawings, and description thereof is omitted.

As shown in the schematic side view of FIG. 1, a paper supply mechanism of a printer according to an embodiment of the present invention includes a roll paper storage unit 1 in front of a feed roller 11 for feeding paper toward a printing unit (not shown). Further, the foldable paper storage unit 2 is juxtaposed adjacent to the front side.

The roll paper storage unit 1 includes a bearing 14 for supporting both ends of a support shaft 4 having a cross section through which the roll paper 10 is inserted (see also FIG. 2) in a detachable manner and without rotating, and a box-shaped roll. A pair of front and rear guide plates 3 for guiding the folded paper 20 when it is used before and after the paper storage unit 1 is provided.

The pair of guide plates 3 are pivotally attached to a pivot 1c formed on the upper edge of each of the rear and side walls 1a, 1b in front of the box-shaped roll paper storage unit 1. When the roll paper 10 is used, it is suspended along the front and rear side walls 1a and 1b and is retracted.

When the pair of guide plates 3 are raised around the respective rotating tines 1c, the stepped portions 4a-1 formed on the distal end surfaces of the cross projections 4a of the support shaft 4 are formed.
(See also FIG. 2) the mutual position and geometry are designed so that they are just engaged and bridged from both sides. When the roll sheet 10 is used by attaching the magnetic sheet 5 to the front end portions of the pair of guide plates 3, the front and rear inner walls 1a and 1b are magnetically attracted.

Further, the pair of guide plates 3 are arranged in a manner shown in FIG.
(Only the right guide plate 3 is shown, and the left guide plate located at the target position with respect to the support shaft 4 is not shown) as shown by the two-dot chain line in FIG. Divide into widths. For example, 114 mm width, 80
In order to cope with folding paper having a width of mm, the width is divided into an 80 mm width and a 34 mm width obtained by subtracting the 80 mm width from the 114 mm width.

When using folding paper having a width of 80 mm, only the guide pieces 3a are raised, and 114 mm
When a folded sheet having a width is used, the guide pieces 3a and 3b are raised. Other paper widths can be dealt with by further dividing based on the same idea.

On the other hand, as shown in the perspective view of FIG. 2, the support shaft 4 has a disk-shaped fixed flange 4b integrally extended to regulate one ear end of the roll paper at a predetermined position, and a roll. A movable flange 4c fitted movably in the axial direction to regulate the other end of the paper having a different paper width, the movable flange 4c being capable of adjusting the distance from the fixed flange 4b. Both ends have a rectangular cross section and a part of the center is a semi-cylindrical surface as in the conventional case.

Next, the operation when using roll paper will be described with reference to FIG. When the roll paper 10 is used, the left roll paper storage unit 1 is used. First,
The roll paper 10 is inserted through the support shaft 4 and inserted into and supported by the bearing 14 of the roll paper storage unit 1. The roll paper 10 is sandwiched between the movable flanges 4c with the fixed flange 4b as a reference, so that the gap between the roll paper 10 and the fixed flange 4b is adjusted to the paper width and fixed to the support shaft 4 by fixing means such as screws (not shown). Then, the leading end of the roll paper 10 is inserted into the feed roller 11 under the drawer guide bar 12 and set.

Next, the operation when using the folding sheet will be described with reference to the schematic side view of FIG. When using the fold sheet 20, the fold sheet storage unit 2 on the right side is used. Here, referring also to FIG. 2, first, when the paper width is, for example, 80 mm, the guide piece 3a
Just turn and wake up. (If the width is 114 mm, the guide pieces 3a and 3b are raised.) Then, only the support shaft 4 is supported on the bearing 14 of the roll paper storage unit 1. The raised end of the guide piece 3a is engaged with the stepped portion 4a-1 of the cross projection 4a of the support shaft 4 and bridges it.

Then, the movable flange 4c of the support shaft 4 is moved to sandwich the guide piece 3a with the fixed flange 4b, and after confirming that the guide piece 3a fits the paper width of the folded paper 20, the screw is fixed to the support shaft 4.

Then, the fold sheet 20 is placed in the fold sheet storage section 2, the leading end of the sheet is taken out, and guided between the bridged guide plate 3 and the flanges 4b and 4c and passed under the guide bar 12, It is inserted into the feed roller 11 and set. The set sheet is sent to the printing section on the other side by the rotation of the feed roller.

As described above, by providing the support shaft with the movable flange capable of adjusting the distance from the fixed flange in accordance with the paper width to be used, the movable flange can be adjusted to accommodate various paper widths of roll paper and folded paper. be able to.

Further, a guide plate is pivotably mounted on the front and rear of the roll paper storage section so as not to interfere with the loaded roll paper, and the guide plates are divided into guide pieces to be used according to the paper width. By raising only the guide piece corresponding to, and bridging the support shaft from both sides,
By using the raised guide piece as a gauge for the paper width, the moving flange can be easily adjusted in position according to different paper widths of the folded paper.

The fold sheet is guided by both flanges of the support shaft and supported by the guide plate so that the fold sheet can pass through the roll paper storage portion without any trouble. It can be easily set with good operability.

In the above description of the embodiment, the guide plate is provided separately along the front and rear side walls of the box-shaped roll paper storage unit, but the front and rear side walls themselves may be formed as guide plates. Although the above embodiment has been described with reference to the paper supply mechanism provided in the label printer, it is needless to say that the present invention can be applied to other apparatuses using roll paper or folding paper.

[0031]

As described in detail above, according to the present invention,
An extremely useful industrial effect is obtained in that the same printer can easily supply both roll paper having various paper widths and continuous folded paper with good operability.
