After printing <28), the total h1 amount is printed (29), and the printing paper is set and fed (30) to prepare for the next printing (31>. In the embodiment described in 11), Since there were two types of printing paper, the hole (() was detected without), but if there were printing papers with different label sizes and there were three or more types of printing paper, the hole (1) was detected. For example, a detector can be constructed by combining eight holes (I, J, and N/A) in two side configurations. That is, one hole (I) on the right, one hole (I) on the right, one hole (I) without a hole, and one (1) hole on the right. There is a method C in which the type of printing paper is set for each combination of , no holes, 1 hole, etc. In addition, the cassette (4) has 11 holes for detecting the cassette.
Since I wore 11, it lacks compatibility with Kasetsu 1-. Therefore, as shown in Figures 9 and 10, a slide plate (1-) is provided in the hole () on the back of the cassette (4) so that the distance between each hole (1) is +11. Compatibility can be improved.Furthermore, the detection of the type of printing paper described in R+!11 is not limited to the above-mentioned embodiment, and is also similar to the following. (I) A convex portion is provided in place of the hole (1), and detection is made by the presence or absence of the convex portion.

(Ii2) A translucent type sensor 4 is set up to sandwich two sheets of paper drawn from the roll in the cassette (), and a predetermined amount of paper is fed when the sensor is installed. Receipt 11) Detects the type of printing paper. The type of printing paper in the cassette (4) detected in the above manner is displayed by indicating the type with an arrow and turning on and off as shown in FIGS. 11 and 121. This display is not limited to the display f1K (11I), but should also be installed in the older brother's room. (

Control Zuru J is a software control system 911. Save the settings for both the label printing control program and receipt printing control program in ROM (!i9), and detect whether the printing paper in the cassette is label paper or Regi I-paper every time the print key on the operation panel is pressed. However, the control mode is changed each time. Moku Fengmei is not limited to the above, but the control means is made up of dedicated hardware, and the hardware that corresponds to the type of printing paper is selected by heat while the Kahit is attached to the attachment part. It also includes. Also, it is convenient to switch between printing modes 1 and 10 automatically when the cassette is replaced, but if the printing paper is not frequently replaced, a manual switch for mode switching may be installed. Then, the operator selects and sets the 7-card by pressing the button 1 to select the type of printing paper. With this configuration, the configurations of the Karen 1 and the mounting portion can be simplified. In the following, other embodiments of the paper transport device will be shown as "j", and those having the same structure will be shown as "-r", and the explanation will be omitted. Platen [A second embodiment in which the take-up reel is driven by the power from one noten roller is shown in Figures 13 to 18.

Let's take it off. The reason why the printer and the electronic scale were integrated in J3 in the embodiment is because the printer of the present invention has the electronic scale [(1) data that can be stored in the printers 1 to 7 l-!I. This is because we thought that the electronic scale and the printer are generally easy to use, but the present invention also includes a system in which the electronic scale and the printer are separate bodies and are electrically connected by a C connection cord or the like. If it is a separate product, it is possible to connect multiple electronic scales to one printer, and it is also possible to handle product delivery and cash receipt by different people. It's convenient. If you use ＞L\Light b IJ d3, put one label on the dispenser and peel it off.
