Of Jo which is formed on the cam surface, one of the cam surfaces on the lower guide, the other cam surface is engaged with the upper guide, the cam member moves
Movement causes the lower guide and upper guide to swing,
Between the guide surface of the upper guide and the guide surface of the upper guide
So as to move relatively separable direction, above and below the center of the print head, the width of each of the elongated recording medium a plurality of kinds of widths
The center of the is to be located .

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the present invention. 1 is a thermal print head (hereinafter referred to as a print head). Reference numeral 3 denotes a platen, 4 denotes a ribbon guide, and 5 denotes a recording medium transport roller (hereinafter, referred to as a transport roller). The transport roller 5 is driven by a motor (not shown). Reference numeral 6 denotes an idle roller, and the idle roller 6 is configured as a pair with the transport roller 5, and the transport roller 5 and the idle roller 6 constitute transport means for the recording medium 2.

Reference numeral 7 denotes a lower guide, which supports the recording medium 2 from below and includes a recording medium 2 including a print head.
The lower guide 7 is formed with an upstream guide surface 7a on the upstream side of the transfer path 8 and a downstream guide surface 7b on the downstream side starting from the print head 1. Outside, a hole 7c and a projection 7d are formed ,
The printer is configured so as to be swingable with respect to the printer main body, and further has a cam receiving portion 7e.

Reference numeral 9 denotes an upper guide, which is composed of an upper guide body 10 and an upper guide support 11. The upper guide body 10 is located above the upstream guide surface 7a, and is formed with the upper guide surfaces 10a, 10a and the support shaft 10b. At the center of the upper guide support 11, the support shaft 1 is provided.
0b is provided with a pair of holes 11a for pivoting itself.
Holes 11b and 11c are drilled, and a spring receiving portion 11e is provided at the distal end portion 11d, and a cam receiving portion 11f is formed below the spring receiving portion 11e . Upper guide body 10 records
Centering on the support shaft 10b in a direction perpendicular to the medium transport direction
The upper guide support 11 swings.
Alternatively, the upper guide support 11 itself is also provided on the printer body 12.
The holes 11b, 1
It swings via 1c. Reference numeral 13 denotes an elastic body made of a plate spring. The elastic body 13 is formed in a substantially U-shape, is fixed to the lower guide 7 by a screw 14, and has a narrow upper guide. Prevents floating in position. Reference numeral 15 denotes a coil spring. The coil spring 15 is located below the spring receiving portion 11e, and urges the upper guide 9 against the recording medium 2 by its elasticity. It is provided as biasing means for positioning.

Reference numeral 16 denotes a cam member.
Has a cam surface 16a which engages with the cam receiving portion 7e of the lower guide 7.
And a cam surface 16b engaging with the cam receiving portion 11f of the upper guide support 11, and the cam surface 16a and the cam surface 1 are formed.
6b is formed in a stepped shape opposite to each other.
A long hole 16c and a long hole 16d are formed so as to be movable back and forth, and a knob 16e is further formed. Although not shown, pins protrude from the printer body 12 in the long holes 16c and 16d.

[0010] With this configuration, the cam member
By moving the 16 knobs 16e back and forth,
Swing the guide and the upper guide,
The guide surface of the guide is relatively close to and separated from the middle of the guide.
Can be moved in any direction.

If a member for guiding the upper surface of the recording medium 2 is provided downstream of the print head 1 in the recording medium transport path 8, it becomes difficult to remove the recording medium 2 when the recording medium 2 is jammed. Therefore, a member for guiding the upper surface of the recording medium 2 is not provided downstream of the print head 1. Reference numeral 17 denotes an ink ribbon, and reference numeral 18 denotes a ribbon cassette.

[0012]

As described above, the present invention provides a cam member.
Movement causes the lower guide and upper guide to swing,
Center the center of each width of the long recording medium on the print head.
The center of the width is assured to be located at the top and bottom of the print head because the center of the width of each tape-shaped recording medium such as a terminal plate nameplate or label tape of multiple widths is located at the lower center. Thus, it is possible to provide a printed recording medium with good appearance. The upper guide includes an upper guide support that swings up and down by movement of the cam member, and a guide.
Surface of the guide surface,
Swingably supported on the upper guide support with the axis in the orthogonal direction
The upper guide main body can hold the recording medium in a well-balanced manner. Moves and successively different types of linear material are collected.
The mounting member is moved up with one hand C as shown in FIG. 3 together with the same type of linear material placed on the mounting member of the storage device and cut to a specific length on the mounting member. Let the other hand D
5, the linear material is gripped at the position of the notch of the side plate and the partition plate or the partition plate and the partition plate, and the bundle of the linear materials is successively moved out of the storage tray, or as shown in FIG. When the short linear material is moved, the short linear material is placed on the placing portion in the pair of standing portions of the placing member and moved upward,
After moving the same type of linear material together with the mounting member to the outside of the storage tray to take out a short linear material, the mounting member is returned to the original position via the positioning unit.
