In the printer device 7 having a paper feeding mechanism for storing the recording paper 1, a printer provided in the printer device for guiding the leading end of the recording paper to the discharge port of the recording device when the recording paper 1 is replaced or loaded. Not using the loading mechanism.

That is, in the loading mechanism, the leading end of the recording paper 1 is positioned at a predetermined recording position via the loading mechanism in the pentor recording device 7. In particular, in recent years, printers in this technical field are increasingly required to be smaller and lighter, and in the paper feeder of the printer as described above, in order to prevent dust or water droplets from entering the recording device, Generally, the opening / closing door 3 is provided so as to be openable / closable integrally with the printer device, and the leading end of the recording paper is loaded at a predetermined position without causing a paper jam or the like mainly when the recording paper is mounted. As described above, conventionally, the loading operation is performed with the opening / closing door opened.

[0004]

[Problems to be solved by the device]

 In a conventional printer having a loading mechanism, the recording paper is replaced or loaded with the door open as described above, and moreover, the recording paper does not get jammed to a predetermined position during loading. It is loaded without being raised, and a process to eliminate bending, bending, etc. at the leading edge of the recording paper is performed so that the leading edge of the recording paper discharge port formed on the opening / closing door will pass smoothly when the opening / closing door is closed. It was necessary.

That is, when the opening / closing door is closed, the leading end of the recording paper sent at the time of loading has to pass through the recording paper discharge port of the opening / closing door by manual feeding or the like. There was a big problem in actual use because of poor performance.

[0006]

[Means for Solving the Problems]

 The present invention is to solve the above problems, and a door open / close detection means for detecting the open / closed state of an open / close door having a discharge port for discharging the front end of a recording paper wound in a roll shape to the outside of the printer device. A recording paper position detecting means for detecting the position of the roll-shaped recording paper front end, and a control means for simultaneously controlling the respective detecting devices and the printer device and the printing operation of the recording portion for actually performing the printing operation. It is provided.

[0007]

[Action]

 According to this configuration, it is detected that the recording paper has reached the front of the opening / closing door according to the predetermined route through the position detecting means provided in the vicinity of the recording paper discharge outlet of the printer during the loading operation. At the same time, the paper feeding operation of the recording paper is once stopped, and then the door open / close detection means detects the open / closed state of the open / close door, and when the open / close door is closed, the recording paper discharge port formed in the open / close door. The paper feed operation is performed in two stages so that the paper feed operation is restarted so that the front end of the recording paper is ejected by a predetermined amount.

Therefore, according to the method of the present invention, the conventional processing of the leading edge of the recording paper for allowing the recording paper to pass through the recording paper discharge port provided on the opening / closing door without any trouble after loading is performed, unlike the conventional method. It is no longer necessary, and as described above, the recording paper replacement and loading operation at the time of loading are performed in two stages, and the detection means for detecting the open / closed state of the door is provided. The leading edge of the recording paper can be easily ejected.

[0009]

Embodiment Next, an embodiment of the present invention will be described in detail with reference to the schematic sectional view shown in FIG. In FIG. 1, 1 is a recording paper which is continuously wound in a roll shape, 2 is a recording device having a recording head for recording data on the recording paper, and 3 is a recording paper ejection section of the recording device. An opening / closing door that can be opened and closed, and has the recording paper discharge port 8. Reference numeral 4 is a detection means for detecting the open / closed state of the door. Reference numeral 5 is a recording paper position detecting means for detecting that the recording paper is loaded to a predetermined position as a result of loading the recording paper in the printer when the recording paper is loaded, and 6 is to be performed by these recording devices. The control unit controls the printing of the data and at the same time controls the recording paper position detecting means and the detecting means for detecting the open / closed state of the door. Reference numeral 7 denotes a printer device.

Next, the operation of the printer device of the present invention will be described. When the recording paper 1 is set in the printer, the opening / closing door 3 is opened and set in a recording paper storage unit (not shown). Next, the leading end of the recording paper 1 is inserted into the loading mechanism in the printer device 7. When the loading mechanism starts the loading operation, the leading edge of the recording paper 1 is sent to the recording paper position detecting means near the recording paper discharge section via a predetermined path in the printer device 7. At this time, the recording paper position detecting means detects that the leading end of the recording paper 1 has been sent to a predetermined position, and sends this detection signal to the control unit 6. The control unit 6 which has received the recording paper position detection signal temporarily stops the paper feeding operation of the recording paper 1 and waits for a detection signal from the next door opening / closing detection unit 4 that detects the door opening / closing state. Next, when the control section 6 receives a door closing detection signal from the door opening / closing detection means 4, the control section 6 sends a paper feeding operation command for the recording paper 1 to the recording device 2 again, and again feeds the recording paper 1 Take action. As a result, the leading edge of the recording paper 1 is sent out of the opening / closing door through the recording paper discharge port 8 provided in the opening / closing door.

Although a reflection type photo sensor is used in the present invention as the recording sheet position detecting means, it can be used in any case as long as it has a similar function such as a transmission type photo sensor. Needless to say. A limit switch was used as the detection means to detect the open / closed state of the door, but this detection means should be usable as long as it has a similar function such as a proximity sensor or photo sensor. Needless to say.

[0012]

[Effect of device]

 As described above, the position detecting means for detecting the position at the time of loading the recording paper and the detecting means for detecting the open / closed state of the door are provided, and by controlling them by the controller, the leading end of the recording paper at the time of loading is rolled. A smooth loading operation can be performed by stopping once just before the paper discharge port and performing the loading operation again when the open / close door is closed, improving the operability and improving the recording paper discharge port. Since there is no need to manually operate the insertion to the paper, it is possible to prevent paper jams.
