Abstract

PURPOSE:To enable the position of the first printing line to be easily adjusted on each of various papers, by minutely feeding a paper by a re-depressing an operating key after intake of the paper and movement of a carriage are completed. CONSTITUTION:On receiving a minute paper feed driving command 115, a paper- feeding motor driving part 105 minutely drives a paper-feeding motor 10 to minutely move the paper upward. The position of an upper end detector 3 is so set that when taking in the paper 4 by depressing the operating key 9, the position of the first printing line on the paper other than a standard paper will be on the lower side of a marker 7. In this case, after the paper is taken in and the carriage 6 is moved to a predetermined position, the operating key 9 or an operating key 8 is again depressed to thereby minutely move the paper upward, and when the first printing line position comes to coincide with the market 7, the depression on the key is stopped, whereby a desired position is made to be the first printing line.

Description

TECHNICAL FIELD The present invention relates to a paper position adjustment circuit for a printer that is capable of adjusting the position of a first print line of a printer with a front inserter.

BACKGROUND OF THE INVENTION FIG. 1 is a perspective view showing a printer with a front inserter to which the present invention is applied, FIG. 2 is a front view showing the main parts of the front inserter, and FIG. 3 is a side view thereof. The front inserter is a mechanism that sucks paper vertically downward into the front of the platen and ejects it vertically in the negative direction.It allows multiple sheets of copy paper to be stacked on top of each other and is inserted into the platen without shifting each copy paper. It is possible to inhale in front of the body.

That is, insert the paper 4 along the guides 1 and 2, press the operation button 9 to rotate the paper feed motor IO, suck the paper 4 downward by the pair of rollers 11 and 20, and press the top edge of the paper. When the upper end detector 3 detects the upper end of the paper 4, the paper feed motor 10 is stopped, and the paper 4 is stopped at a predetermined position on the platen 5. Thereafter, the carriage motor 13 rotates to move the carriage 6 from side to side in the figure via the wire 12 to a predetermined position on the paper 4. In addition, carriage 6
A marker 7 indicating the position of the print line is marked. Also, by pressing the operation button 8, the paper feed motor 10
rotates in the opposite direction and discharges the paper 4 upward in the figure.

The conventional apparatus described above has a drawback in that the position of the first print line on the paper 4 is fixed, and therefore the position of the first print line cannot be changed depending on the type of printing paper. This is extremely inconvenient, and depending on the type of paper,
It is desirable to be able to arbitrarily adjust the position of the printed line.

OBJECTS OF THE INVENTION An object of the present invention is to provide a paper position adjustment circuit for a printer that can solve the above-mentioned conventional drawbacks and arbitrarily adjust the position of the first print line.

Structure of the Invention The paper position adjustment circuit of the printer of the present invention includes a pair of rollers for feeding the paper vertically to the front of the platen, and a printing unit located in front of the platen, which moves parallel to the platen. In a printer with a front inserter, the printer includes a top edge detector for detecting the top edge of the paper, an operation button for sucking the paper, an operation button for ejecting the paper, and a push button for the operation button. an operating section that starts the paper processing section by a command signal; and an operating section that starts a paper feed motor drive section in response to a paper suction command signal from the operating section and stops the paper feeding motor drive section in accordance with the output of the first end detector. a paper suction processing unit that sends a suction state signal to the machine and activates a carriage movement processing unit in response to a suction end signal; and a paper suction processing unit that activates a gear ridge motor drive unit in response to the suction end signal to move the carriage in a lateral direction. a carriage movement processing section that reports completion to the operation section using a completion report signal; and a paper adjustment processing section that sends a minute paper feed drive command to the paper feed motor drive section in response to an adjustment command signal from the operation section; The operation unit receives the termination signal and the inhalation state IE.
When the multiplication signal is received, the first printing unit adjustment mode is entered, and an adjustment command signal is sent to the paper adjustment processing unit by pressing the operation button, and when the paper feed motor drive unit receives a minute paper feed drive command, is characterized in that the paper feed motor is configured to be slightly driven.

Embodiments of the Invention Next, the present invention will be described in detail with reference to the drawings.

FIG. 4 is a block diagram showing one embodiment of the present invention.

That is, by pressing the operation button 9, the paper suction command signal l1 is
an operation unit 101 that outputs 1 and starts the paper processing unit;
A drive command signal 114 is output in response to a paper suction command signal 111 from the operation unit 101, and the paper feed motor drive unit 105
When the paper upper end detection signal 11B is input from the upper end detector 3, the drive command signal 114 is stopped and the suction state signal 1 is input.
12 to the operation unit 101 and further activates the carriage movement processing unit 104 in response to the suction end signal 113; and a paper feed unit that outputs a drive signal 118 upon receiving the drive command signal 114 to rotate the paper feed motor IO. Motor drive part! 05 and the inhalation end signal 1
13 outputs a carriage drive command 117 to start the carriage motor drive section 106 to move the carriage in the lateral direction, and to complete the movement of the carriage, an end signal 12 is output.
0 to the operating unit 101; and a paper adjustment processing unit 10 that sends a minute paper feed drive command 115 to the paper feed motor drive unit 105 in response to an adjustment command signal 110 from the operating unit 101.
It consists of 2.

When the operation unit lot receives the end signal 120 and the suction state signal +12, it enters the first printing unit adjustment mode and transmits the adjustment command signal 110 to the paper adjustment process by pressing the operation button 8 or 9. The paper adjustment processing section 102 sends a minute paper feed drive command 115 to the paper feed motor drive section 105. When the paper feed motor drive unit 105 receives the minute paper feed drive command 115, it slightly moves the paper in the -L direction by slightly driving the paper feed motor O.

In this embodiment, the paper 4 is initially pressed by pressing the operation button 9.
For most types of paper (standard paper), the position of the upper edge detector 3 is set so that the position of the first print line of the paper 4 matches the position of the marker 7, as in the past. However, for other types of paper, the position of the upper edge detector 3 is set so that the position of the first print line of the paper is below the marker 7. In that case, after the carriage 6 has moved to a predetermined position by sucking in the paper, press the operation button 9 or 8 again to move the paper slightly upward, and then move the paper upward until the first printing line By stopping the pressing of the button when the position coincides with the marker 7, it is possible to set an arbitrary position as the first printing line.

Effects of the Invention As described above, in the present invention, after the suction of the paper and the movement of the carriage are completed, the paper is moved slightly by pressing the operation button again. This has the effect that the position of the first printing line can be easily adjusted by using the method.
